These are the berry bushes that provide the blueberries that we often see at the local supermarket. Furthermore, according to the patent, the weight of the picking head is supported only by a pair of skids mounted to the ends of the picking head. A later development is reported in Canadian Pat. The falling berries encountered a conveyor running axially within the reel, which conveyor carried the berries laterally to another conveyor running to the rear of the harvester, from which they were deposited into a flat or other container. Developing a Lowbush Blueberry Harvester Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Transactions of … In the spring you'll see white flowers with a pink tinge growing in clusters. 6 is a partial elevation of the tine mounting arrangement. Many passes are required to harvest a large field. FIG. Although, in these types of conditions, mulching would be recommended. They aren't very often cultivated specifically for their berries on a large scale. FIG. The invention relates to a harvester for lowbush berries such as wild blueberries. Some varieties can grow in zone 2 or in zone 7. 8 is a partial plan view of the harvester of FIG. Once planted and waiting for the cutting to establish, it should be kept warm and moist. Vaccinium angustifolium Aiton – lowbush blueberry Subordinate Taxa. It's glossy foliage turns maroon-purple in the fall. 3 is a perspective view of one picking head and the conveyors associated therewith. Because this shrub doesn't like root disturbance, especially as it's growing, it's best to sow the seeds in pots. 2 that the two picking heads are laterally and longitudinally offset from each other, although there is a slight amount of lateral overlap to ensure that all bushes in the path of the harvester 10 are harvested. As the cable is pulled further downwardly the counterweights will rise to the upper limit 88 and will be prevented from any further upwards movement. Gemma is a Freelance Writer and Animal Welfare Advocate. 1,249,727 of Bragg Lumber Company. The brush preferably has a higher rotational speed than the reel to provide the necessary cleaning forces. This has the effect of simultaneously raising or lowering the counterweight 84 and the picking head 18 at the forward end of the harvester. A pair of vertical-members 236 extends downwardly from the rear frame member 232 adjacent the ends thereof and mount between them at the lower ends thereof a transversely extending roller 238 which spans the width of the reel 222 and supports the frame portion 228 on the ground. After the point Z the cam flattens somewhat to turn the tines more towards the vertical so that they Will contact and enter the rotating brush for cleaning and debris removal. The harvester of claim 1 wherein the tines carried by each reel are mounted to a plurality of laterally extending, circumferentially spaced rods Pivotally mounted to the reel, each rod having a roller member secured thereto at one end thereof for cam-following engagement with cam means carried by said frame means, said cam means being shaped to ensure a generally vertical orientation for said tines as they approach the Plants to be harvested, a generally horizontal orientation as they pass through the Plants, a generally circumferential orientation as they elevate harvested berries to the top of the reel, and a generally upright orientation to thereafter engage rotating brush means near the top of the reel. FIG. Owner name: At the upper end thereof and below the discharge portion 106 is a plastic or sheet metal pan 108 which spreads and redirects the berries, as well as debris such as leaves, stems, et cetera, backwards and downwards towards the reel 60. Nutrients Late lowbush blueberry, Vaccinium angustifolium Go to results page Mountain cranberry, Vaccinium vitis-idaea Go to results page Northern blueberry, Vaccinium boreale In the spring you'll see white flowers with a pink tinge growing in clusters. FIG. 13. Lowbush blueberry plants, also known as "Maine blueberries", vary in height and form and are comprised of 3 principal species: Vaccinium: angustifolium, pallidum, and myrtilloides.They are found throughout the Northeast and Midwest of the USA, and in Canada. 7 and 10 it will be seen that a generally cylindrical brush 272 extending the width of the reel 222 is mounted thereabove almost directly on the centreline of the reel 222. In spring, it features attractive clusters of small, waxy, white, pink-tinged, bell-shaped flowers. The operation of the counterbalance system is illustrated in FIGS. 14 in various positions depending on the operation thereof. All components of the harvester of this invention are operated hydraulically in a conventional manner. The frame 220 includes two distinct portions, namely an upper, outer portion 224 and a lower inner portion 226 which is movable vertically relative to the upper portion 224. Key words: agricultural engineering, blueberry harvester, picking reel, constructive and kinematics parameters. The kinematics parameters include the angular speed of the picking reel, the machine velocity and the kinematics number. 4, and assuming a counterclockwise rotation of the reel, it will be seen that the cam 68 is formed so that the tines 62 have a generally vertical orientation as they descend from the point X towards the point Y. 4 shows an end view of a picking head and reel with a simplified frame 58', without showing the reel per se. Just before the point A the cam track 270 jogs back to its circular path at point A to quickly bring the tines back to an orientation lying along a circular arc. Contained within each area 42, 44 is a picking head 18, it being seen from FIG. In the wild, these bushes are usually found in forest glades or meadows with sandy soils. 12. Walk Behind Harvesters At last a blueberry harvester that does not require a tractor. 10 and 11 are end and front views respectively of the picking head of FIG. Pickers are paid an average of 10 to 12 cents per pound. With this system there is less loss of berries from the "back " of the tines as they elevate towards the top of the reel. 1 and 2 illustrate a first embodiment of the lowbush berry harvester 10 of the present invention as being mounted to a typical farm tractor 12 which has been modified to run in reverse. A flat reinforcing bar 71 is also welded to the underside of the box member 70 for added strength and to prevent loosening of the tines. The truss section 20, in turn, is connected to the three-point hitch 22 of the tractor so that the truss section is pushed by the tractor as it proceeds in the direction of travel. The present invention relates to a berry harvester in general and, in particular, to a harvester for lowbush berries such as strawberries or wild blueberries. As seen in FIG. The rhizomes don't like to be dislodged during those early years. 12. The mulch will also help preserve soil moisture in drier regions. This reduces the number of tine Passes through a berry Plant for each rotation of the reel and avoids extensive damage to the Plants. FIG. In FIGS. These modifications have given yields equivalent to hand harvesting while retaining high quality fruit of lowbush blueberry (V. angustifolium and V. myrtilloides) (Yarborough, 2002). The tines, as the reel rotated, were combed through the bushes so as to pull the berries therefrom and then they carried the berries upwardly until they fell therefrom into the centre of the reel. 2 and 3 and comprise a laterally extending conveyor 98 housed within each reel 60 adapted, as is the Chisholm-Ryder conveyor, to receive berries that have been picked by tile tines 62, carried to the top of the reel thereby and then released to fall into the reel so o as to land on the conveyor 98. The harvester of claim 3 wherein a rotatable pulley is provided at the upper end of said tension support member, said tension member passing under said last-mentioned pulley. It will be appreciated that the picking head of the harvester is very heavy and that its weight can be damaging to the bushes over which it travels and can make it difficult for the head to travel smoothly over uneven ground. Midhigh, also called half-high, blueberries should be planted 2 to 3 feet apart. 1 and 2. Otherwise the tractor wheels will crush berries in its path. The harvester of claim 9 wherein said second conveyor means receives berries from said deflector shield and transports them rearwardly and upwardly for reception in container means Positioned below the free upper end thereof at the berry collection station. 1 and 2 each of the picking heads is provided with its own independent counterbalance system 26, whereby each picking head can be independently controlled by the operator such that one head can be raised to clear a rock or other obstacle while the other head continues to harvest berries in its path. 12 and 13. With two four foot wide picking heads the present invention can harvest a swath of seven to eight feet in width, a substantial increase over the prior patented harvesters. Lowbush Blueberries (Vaccinium angustifolium) are low-growing wild shrubs native to North America. The lower frame portion is slightly narrower and shorter than the upper frame portion 224. Because the harvest of the blueberry fruit is the largest expense in producing the crop (Yarborough, 1992b), there has always been interested in reducing this cost with a mechanical harvester. After passing through the brush 66 the tines start their descent again and tile process continues. … At one end of the box member 70 is a roller member 72 mounted within lugs 74. In this embodiment the truss section 204 includes a vertically oriented frame portion 208, connected to the tractor via the three-point hitch 210. This has the effect of again progressively opening the tines 62 outwardly so that as they approach the ground they are almost pointing vertically downwardly. Why wouldn't you want to harvest the berries growing on your shrub to take advantage of their health benefits and delicious flavor. 16E and 16F the counterweights 310 will be elevated to contact the limit stops 308, at which point no further elevation thereof is possible. B825: A Comparison of Lowbush Blueberry Harvesting Technologies: Experimental and Economic Results from the 1988 Field Tests in Washington County, Maine Michele C. Marra Timothy A. Each picking head mounts a rotating, tine-carrying reel therein and is connected to one end of a counterbalance system, the other end of the system being carried by the tractor. Sometimes they even grow along the edges of boggy wetlands. In particular, it is necessary to harvest a field in one direction only so that the tractor does not travel over bushes from which berries have not already been stripped. Continued retraction of the rod 298 will cause a pulling action only on that portion of the tension member 280 leading to the picking head 206 and consequently the head 206 will be elevated on its own relative to the ground. Key words: Lowbush blueberries, the height of which is … Forward of the cab, the tension member passes around another pulley 288 and extends vertically upwardly adjacent a counterweight member 290 mounted to the side of the tractor and shown in detail in FIGS. This picking head operates the same as the picking head 18 and can be used in place thereof. It should be noted strongly at the outset that the NIMCO harvester used in the field experiments was the prototype machine. Between these positions as seen in FIG. The present harvester uses a picking head that is based on the Chisholm-Ryder head, with a few modifications thereto that result in improved efficiency. It is illustrated in association with the harvester of the second embodiment. 4 to 6. 12 the cam track is preferably milled from a solid piece of metal such as steel, the track 270 being defined between inner and outer portions 274, 276 of the piece. She has been involved in the Pet Industry for over 15 years. The harvester of claim 1 wherein said counterbalance means includes, for each of said picking heads: a tension member attached at one end to the picking head and extending towards the tractor over a plurality of pulley members to counterweight means attached to the other end thereof; said counterweight means being movable vertically between upper and lower limits; and an adjustable hydraulic cylinder member engaging said tension member between a pair of said pulley members for adjusting said counterbalance means and for elevating or lowering the picking head as desired. This means that there will be little damage to the picking head if it encounters obstacles such as rocks or tree stumps during harvesting. These can then be planted out to their permanent position once the seedlings are established. Skids 96 or 96' provided at each end of a picking head can help to support the head above the ground and are intended to prevent the tines from digging into the ground if the harvester encounters a hummock or a sharp depression in the ground. FIGS. PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. The berry collecting aspects of tile invention are best seen in FIGS. 14 and 15 are side and end views of the operative component of the counterbalance means for this embodiment. The frame portions 208, 212 and 214 are conventional in construction, having suitable reinforcements to ensure rigidity. It will be appreciated that one of the tension members will extend along one side of the harvester and the tractor While the other tension member passes along the other side of the harvester and the tractor. 4), so as to interact with the tines 62 when they are at to top of the reel. Extending downwardly from each of the frame members 230 and 232 is a pair of hollow rectangular tube members 234. Starting at about the point B the berries cradled by the tines begin to fall into the interior of the reel 222 for collection by the internal conveyor system as in the first embodiment and the prior art. Turning now to FIGS. Once the necessity for raising the picking head has passed, the adjustable tension member 92 is operated in the opposite direction to lower the picking head by itself and then the picking head and the counterweights together. A rotating brush 66 is mounted in the frame 58 above the reel 60 so as to engage the tines 62 at the top of their travel, the brush removing debris from the tines and also dislodging therefrom berries that .did not fall from the tines of their own accord, as will be described below. 8. If you plan to feed your Lowbush Blueberry bush, make sure you select a fertilizer designed for acid-loving species. FIG. Using a thin layer of organic mulch to cover the ground around young shrubs can help to protect the roots and rhizomes. It is also a favorite of recreational berry pickers, black bears, coyotes, racoons, foxes, porcupines, white-tailed deer and birds. They are followed by abundant, juicy and edible blue berries in summer - a delight for birds, wildlife and humans alike! Lowbush blueberries should be planted 2 feet apart. 12 is an end view of the cam arrangement for the tines of the second embodiment. While it did work it was not particularly efficient and it did not operate satisfactorily on uneven ground. They're just rather picky about soil conditions. 11. Also, the harvested path is limited to the width of the picking head, typically 3 to 4 feet. 1. Blueberry jam is made from blueberries, sugar, water, and fruit pectin. Mechanical harvesters date back to the late 1960's, having been developed by individual berry farmers or by companies that see the business as a profitable one. FIG. Centrally of each frame member 254 there is provided a stub member 258 to which is connected one end of a two-way hydraulic cylinder 260, the rod 262 of which is connected to a corresponding stub member 264 affixed to the front and rear frame members of the upper frame portion 224. A counterbalance system reduces the effective weight of the picking heads acting on the ground and makes it easier to clear obstacles and to raise the heads for turning or road travel. FIGS. A vertical rectangular frame 46 is provided at the rear of the truss section and is connected to the tractor's three-point hitch 22 by connecting members 48, 50 in a conventional manner. 14 and 15. 9 is a partial plan view of the picking head of the second embodiment. After the point B at the upper rear thereof the cam track 270 deviates from its circular path, extending inwardly in stages towards the point C, almost in a direction tangential to the circular reel 222. The reel 222 is similar to the reel of the first embodiment and to that the Chisholm-Ryder harvester. Can be used as a ground cover. A tongue member 53 is pivotally connected to and extends rearwardly from the leg member for pivotal connection to the trailing picking head 18 so that the head is capable of roll and pitch movements to accommodate irregularities in the contours of the ground. The Spruce uses cookies to provide you with a great user experience. 12 and 13 it will be seen that the cam track 270 has a lower and rearward generally circular Portion of about 180° between about 4 o'clock and about 10 o'clock as identified by the letters A and B. 1 is an elevational view of a first embodiment of the harvester of this invention.
