Patent number: 7117661Abstract: A method and a system for collection of harvested tree-fruit having a collection device mounted on a hauled cart. For fruit collection, two arms are extended under the foliage of a tree to spread an apron hung between them, in a fruit receiving position. After harvesting is completed, and the apron contains the harvested fruit, the arms draw the apron away from under the tree, and swing through an arc of a circle to stop in a fruit discharge position, where fruit is discharged by gravity into the open top opening of the cart. Then, the arms are returned back from the discharge position to the fruit receiving position.Type: GrantFiled: December 10, 2004Date of Patent: October 10, 2006Assignee: Dotan Ltd.Inventors: David Chiel, Eitan Zehavi

Patent number: 6978591Abstract: A vehicle-carried Tree-Trunk Shaker (TTS) for harvesting tree fruit is configured to prevent the transmission of vibrations from a vibration generator (4) to the TTS and to the vehicle, and for optimal shaking efficiently. Currently, TTSs are allowed to shake multi-directionally and chaotically, convey destructive vibrations to the TTS and to the vehicle, and have low harvesting efficiency. The remedy consists of shaking the trunk only in perpendicular to a pair of jaws (6, 8) clamping the trunk (T), with a unidirectional linear vibration generator vibrating transversally to the trunk. A beam (16) is configured to support the clamping jaws and the vibration generator to form a rigid structure restricted to swivel about a vertical pivot shaft (42) coupled to the vehicle. Thereby there is allowed but a single lateral degree of freedom of motion. Possibly, two vertical pivot shafts (42, 48) are used to that end.Type: GrantFiled: February 26, 2002Date of Patent: December 27, 2005Assignee: Dotan Ltd.Inventors: Eitan Zehavi, David Chiel

Patent number: 6952914Abstract: A deflector (10) for collecting and guiding harvested tree-fruit is implemented for resilient recovery from collisions with obstacles in the field. The deflector is coupled in cantilever to boom harvester (4) mounted on a vehicle (2). The harvester has a telescopic boom (8) with a mobile portion (14) terminated by a clamp (6) able to move in horizontal and in vertical translation towards and along a tree trunk (T). The deflector is coupled to the mobile portion for slaved translation with the clamp. Implemented as an array of separate ribs (32) flexibly coupled together and made of flexible elastic plastic material such as fiberglass, the deflector is lightweight and flexes upon collision to resiliently recover shape after the collision. Being lightweight, the cantilever does not destabilize the vehicle. The structure and the materials of construction of the deflector prevent transmission of vibrations generated by the vibrator (12) used to shake the trunk when harvesting.Type: GrantFiled: November 5, 2003Date of Patent: October 11, 2005Inventors: Eitan Zehavi, David Chiel

Patent number: 5860273Abstract: A compliant engagement member for use with tree-shaking apparatus that resists deformation along the axis of vibration, thereby avoiding dissipation of vibrational energy, yet allows sufficient off-axis deformation to prevent slippage and consequent abrasion of the tree. The engagement member includes a pouch for containing a variable amount of a liquid lubricant; means for conducting a liquid lubricant to and from the pouch; and means for flexibly coupling the pouch to the tree-shaking apparatus. The invention preferably also includes a blanket surrounding at least part of the pouch and frictionally engaging both the pouch and the tree, adding further resistance to slippage against (and consequent injury to) the tree. Lateral inward movement of the shaking device compresses the lubricant pouch against the interior of the contact blanket. The pouch either releases lubricant or is packed sufficiently tightly with lubricant to resist deformation as a result of this compression.Type: GrantFiled: January 17, 1996Date of Patent: January 19, 1999Assignee: Eitan ZehaviInventors: Matti Laserson, Eitan Zehavi

Patent number: 5816037Abstract: A tree-shaking apparatus includes a vibration mechanism of conventional design mounted on a movable, tilted frame support that serves to deflect falling harvest onto a conveyor and collection assembly, which is mounted on a separately movable frame support. The shaker assembly has a peaked configuration with grooves extending away from the peak and toward the shaker. A pair of upwardly inclined walls flank the peaked walls at their outer edges, preventing harvested material from rolling or bouncing off the sides of the frame. Uniting the two units are a series of cooperative, pivotable guides extending from each of the units. When extended during collection, the guides from the shaker assembly overlay the guides from the collection assembly, forming a substantially continuous downward path from the shaker assembly to the conveyor.Type: GrantFiled: September 24, 1996Date of Patent: October 6, 1998Inventors: David Chiel, Eitan Zehavi

Patent number: 5513484Abstract: A transfer station for collecting and transferring harvested material to large transport vehicles includes a hopper, in which harvested material accumulates, supported on a rigid frame. The hopper may be elevated from a lower "collection" height to an upper "transfer" height that facilitates release of harvested material into the transport vehicle. In one embodiment, the contents of the hopper are poured into a collection vehicle by tilting the entire transfer-station frame. In a second embodiment of the invention, the transfer-station frame does not tilt. Instead, the hopper is equipped with a sloped floor member. When lifted vertically and positioned over a collection vehicle, the hopper discharges by gravity as soon as an opening is established at the base of the slope.Type: GrantFiled: July 21, 1994Date of Patent: May 7, 1996Inventors: Eitan Zehavi, Matti Laserson, Steven Frank

Patent number: 5473875Abstract: A tree-shaking apparatus that includes a pair of vibration units whose eccentric rotators turn at identical speeds but in opposite directions. During operation, rotation of the eccentric members is coordinated by a controller such that their asymmetric portions align at two diametrically opposed points but lie precisely out of phase during the remainder of the rotation cycle. This action causes the tree to shake along a single axis, specified by the chosen alignment of the rotators, with vibratory forces along all other directions canceling out. A controller systematically alters the direction and frequency of shaking and monitors the resulting change in vibration amplitude, selecting, as a final shaking axis and frequency, those which correspond to the largest amplitude.Type: GrantFiled: December 9, 1993Date of Patent: December 12, 1995Inventors: Eitan Zehavi, David Chiel
