Lowbush Blueberries have been known to survive even when temperatures hit as low as -40°c. 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. 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. FIG. 16A to 16F show the component of FIG. This has the effect of progressively opening the tines upwardly between the points B and C so that they can be engaged by the cleaning brush 272, to be described later. The lower frame portion 226 is also rectangular in outline, having front and rear frame members 240, 242 and end members 244. 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. 13 the tines 62 are closed relative to the reel so that they form an enclosed arc as they strip the berries from the plants at the bottom of the reel and cradle and hold the berries therebetween and against the box member 70 as the tines move upwardly, to the left in FIG. FIGS. KOKAN 500S is a towed behind harvester that efficiently harvests blueberry, raspberry, blackberry, black currents, haskap and other berries. The reel 222 is similar to the reel of the first embodiment and to that the Chisholm-Ryder harvester. The Spruce uses cookies to provide you with a great user experience. show a counterbalance system 278 which can be used with either the harvester of the first embodiment or the harvester of the second embodiment. Lowbush Blueberry Information. 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. If you're using the shrub as a ground-covering across a wider space, it can be mowed to the ground in late fall once the leaves have fallen. The harvester of claim 1 wherein said tractor is a standard farm tractor suitably modified to operate in reverse, with said truss section and picking heads mounted at what would normally be the rear of the tractor, whereby said reels will pick the berries in advance of the tractor. (f) counterbalance means mounted on the tractor for automatically reducing the weight of said picking heads. A single counterweight member can be used, or as illustrated, a plurality of counterweights can be provided on the pole 86. Most of the debris will be flung from the brush away from the reel 222 and its internal conveyor, while most of the heavier berries will drop into the internal conveyor. Both of these wild blueberry whole-fruit powders are non-GMO, vegan, gluten-free, Kosher and contain no additives, excipients or carriers. As mentioned above, this pulls the tension member or cable 76 downwardly between the rearward compression supports 82 and raises both the counterweights 84 and the picking head. Vaccinium angustifolium (Lowbush Blueberry) is an American beauty that puts on a long-lasting show in the landscape. 11. In the spring you'll see white flowers with a pink tinge growing in clusters. However, the Present reel exhibits distinct differences in the manner in which the harvesting tines are controlled. 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. With this embodiment there are Preferably ten rods evenly spaced circumferentially about the reel 222, rather than the twelve of the first embodiment. After passing through the brush 66 the tines start their descent again and tile process continues. Application filed by Collins Border Holdings Ltd. It's possible to propagate Lowbush Blueberry from half-ripe wood cuttings, but it's a slow process, and it isn't always successful. They aren't very often cultivated specifically for their berries on a large scale. With reference to FIG. The harvester of claim 7 wherein said counterweight means comprises a tube member mounted to the tractor, the tube member mounting said hydraulic cylinder member therein with one of said pulley members being attached to said hydraulic cylinder member, said tube member also mounting said pair of pulley members opposite each other at one end thereof whereby said tension member extends around one of said pair of pulley members, around the pulley member attached to said hydraulic cylinder member and around the other of said pair of pulley members for connection to said counterweight means. Standing water can cause damage to the root system. It should be noted strongly at the outset that the NIMCO harvester used in the field experiments was the prototype machine. A slow-release, soluble, ammonium nitrogen granular variety that is marketed for plants like rhododendrons or azaleas will be a good option. At one end of the box member 70 is a roller member 72 mounted within lugs 74. 2 it will be seen that tile truss section 20 includes laterally and longitudinally extending frame members 28,30, 32, 34, 36, 38, and 40 which together define longitudinally and laterally offset rectangular areas 42 and 44. The counterbalance means 26 will now be described, with particular reference to FIGS. They produce sweet, healthy fruit … Needless to say, the skid 96,96' is mounted to the frame 58,58' at only a single point to allow for the pivotal adjustment movement controlled by the cylinder 124. With reference to FIG. During the summer the small, sweet, edible berries begin to ripen. This species will provide interest in your garden throughout the year. 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 compression support members to counterweight means attached to the other end thereof; said counterweight means being movable vertically between upper and lower limits; and at least one adjustable tension support member engaging said tension member between a pair of said compression support members for adjusting said counterbalance means and for elevating or lowering the picking head as desired. 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. 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. 16A through 16F, it being noted that the tension member 280 passes over the pulleys 300 then into the tube 292 and around the pulley 298, then upwards again to pass over the pulley 304, and then downwards for connection to the counterweights 310. A blower 110 mounted to the framework that supports the angled portion of the conveyor directs high speed air through a flat nozzle 112 back towards the exit end of the pan 108, the air exiting the nozzle serving to blow the debris away, while allowing the picked berries to fall down to a second conveyor 114. 16C and 16D, the effect will be to lift both the counterweights 310 and the picking heads 206 relative to the lowest positions thereof. 961,275 of The Chisholm-Ryder Company. Even though the picking heads may not come clear of the ground some, perhaps as much as 75%, of the weight thereof can be relieved. An elongated bar or rod 73 welded to the bar 71 at its outer edge acts as a berry shelf to help retain harvested berries against the bar 71 as the tines move upwardly on the reel towards their dumping position. The cylinders 260 are used to control the picking height and they help to keep the pitch angle of the tines constant with changes in the height of the picking head above the ground. The picking head 18 includes a surrounding frame 58 and a reel 60 bearingly supported within the frame for rotation about an axis which is transverse to the direction of harvester travel. Be aware that mowing will mean you won't see any harvest the following season, so you may want to only prune some of the plants one year, and the others the following. Blueberry. A later development is reported in Canadian Pat. 14 and 15 are side and end views of the operative component of the counterbalance means for this embodiment. When the rod 298 is fully retracted as in FIGS. 5 and 6). This has the effect of altering, albeit slightly, the pitch angle for each tine due to the pivoting nature of the height adjustment. The brush 66 forces debris from between the tines and also promotes the discharge of berries from the tines into the reel. If you're using a raking technique to gather up the ripe berries, this can be too harsh for the young plant. It prefers evenly moist conditions, especially during the growing season. Centrally of the offset area 42 is a forwardly extending arm member 52 having a depending leg member 54 at the free forward end thereof, the arm member 52 being braced by angled reinforcing member 56. The tractor operator will have appropriate controls to ensure that he can control the operation of each component on an individual basis in order to ensure safe and efficient harvesting of the berry crop. They can do well in sunny regions, and are also fairly hardy. 2 is a plan view of the harvester of FIG. Each skid is designed to have a long generally flat running surface 120 while a sharply curved 122 or angled 122' forward section helps the skid to ride over obstacles. 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. 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. The picking heads 206 are situated so that they are offset one from the other both laterally and longitudinally of the direction of travel. The invention relates to a harvester for lowbush berries such as wild blueberries. The conveyor 114 is similar to the conveyor 98, having a wide, sectioned belt 116 with flights 100 thereon about every 2 inches. 1 and 2. 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. FIG. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. Another pulley 304 is mounted to a bracket 306 on the side of the tube 292 opposite and in line with the pulleys 300. The brush 272 will engage the tines 62 as they are directed thereinto by the cam track 270 and will force from the tine berries that have become lodged in the tines and debris, such as leaves or stems that were caught by the tines during harvesting. If you just have one or two shrubs, pruning to remove old sections of growth or those that are not as healthy will be the main requirement. Box 79 Addison, Maine 04606. Key words: agricultural engineering, blueberry harvester, picking reel, constructive and kinematics parameters. This reduces the number of tine Passes through a berry Plant for each rotation of the reel and avoids extensive damage to the Plants. The brush will move much of the debris away from the reel itself but it will also cause some debris to enter the reel, which debris will be removed from the harvested berries by the blower system previously described. By mounting the blower at the discharge end of the angled portion of the conveyor 98 there is very little debris in the berries as they are collected in flats at the end of the conveyor 114. In the fall, the dainty foliage turns shades of vibrant red, providing a much-needed splash of color at that time of year. 5 is an end view of a berry picking tine and its mounting arrangement. Small, low growing 6" to 2' high plant produces berries in July and August. 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. 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. ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNORS:COLLINS, GEORGE E.;COLLINS, JOHN E.;COLLINS, MICHAEL G.;REEL/FRAME:006750/0780, Free format text: If the conditions are right, this shrub will make a pretty and low-maintenance ground cover option for areas without much footfall or for along border edges. The counterweight member 290 includes a hollow tube 292 having an hydraulic cylinder 294 mounted therein, with the bottom of the cylinder adjacent the bottom of the tube. Introducing "One Thing": A New Video Series, The Spruce Gardening & Plant Care Review Board, The Spruce Renovations and Repair Review Board, select a fertilizer designed for acid-loving species. A pair of stub members 246 is welded to each of the front and rear frame members 240, 242 in alignment with, and for sliding reception in, corresponding tube members 234. provide a double bonus when grown in the home garden. Nutrients An hydraulic cylinder 124 at the rear of the skid, mounted as well to the picking head frame 58 or 58' is used to adjust the height of the reel above the ground. The revised picking head is the subject of a copending, commonly assigned, concurrently filed patent application. This prepares the tines for a generally vertical entrance into the plants to be harvested. By mounting the picking heads so that they precede the tractor during harvesting it is possible to harvest the field in any direction without substantial damage to unharvested bushes, contrary to the situation with the Bragg harvester. FIG. The typical manner of blueberry picking has involved the use of a hand tool wielded by an individual picker, the tool being like a combination comb and scoop, which is moved through the berries to scrape them from the bushes and collect them in a funnel-like portion of the tool. 9. Lowbush blueberry cultivation on harvested peat fields is of recent interest and data about the pH demands of lowbush blueberry plants on these conditions are still insufficient, although some experiments have been made in this respect (Noormets et al., 2002).
