Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fruit harvesting equipment, and specifically relates to a fruit picking device. BACKGROUND

[0002] The fruit is generally collected by mechanical vibration or artificial knocking to make the ripe fruit on the tree fall down, and then the fruit is picked up and cleaned by a ground fruit picking and cleaning device. The jujube, walnut or tea fruit can be harvested by this method.

[0003] The applicant applied for a utility model patent application for a cleaning device for picking up fruits on December 6, 2024, with the application number 202423024823.6. The patent application discloses a fruit picking assembly, which includes a first driving wheel, a first transmission chain, a first crossbar and a first driven wheel. The first driving wheel, the first driven wheel and the first transmission chain are all provided with two and are symmetrically distributed left and right. The two first driving wheels are fixedly connected with the third transmission shaft. The first driving wheel and the first driven wheel on the same side are both connected with a first transmission chain. The two first transmission chains are fixedly connected through a plurality of first crossbars parallel to the third transmission shaft. A plurality of tines are fixedly arranged on the side of the first crossbar away from the first transmission chain. The tines are arranged at equal intervals along the first crossbar. The bottom of the tine is provided with an inclined fruit picking plate. The bottom of the frame is provided with wheels on both sides. The top of the tine is flush with the lowest part of the wheel and the ground when it moves to the lowest part.

[0004] Since the tines are fixedly connected with the first crossbar and the tines themselves do not have elasticity, when the cleaning device moves and encounters a protruding hard stone on the ground, the collision between the tines and the stone will cause the tines at that position to deform rigidly. After a long period of use, the distance between the tines that move to the bottom and the ground will increase, causing the tines at that position to be unable to move the fallen fruit on the ground, resulting in the problem of missed picking. Frequent maintenance is required, and during maintenance, the mounting plate needs to be removed, the deformed tines need to be ground off, and then new tines need to be welded, which is time-consuming and laborious.

[0005] Secondly, when the frame continues to move, since the two sides of the fruit picking plate are fixedly connected with the frame, when the bottom of the fruit picking plate collides with the protruding hard stone on the ground, the frame will be lifted as a whole by the protruding stone, causing a gap between the bottom and the top of the fruit picking plate. The fallen fruit moved by the tines will leak from the bottom of the fruit picking plate and cannot be moved to the upper surface of the tine plate, resulting in the problems of easy deformation and damage of the fruit picking plate and missed picking.

[0006] Chinese Patent No. ZL202122604150.1 discloses a floor fruit picking device with profiling function, which is composed of a cross beam, a first picking part, a second picking part, a third picking part, a first fruit collector and a second fruit collector. The first picking part, the second picking part and the third picking part are evenly arranged on the cross beam in sequence. The first fruit collector and the second fruit collector are arranged on the first picking part and the second picking part respectively. The first picking part, the second picking part and the third picking part have the same structure and are composed of a profiling roller frame, a harvesting plate, a roller brush, a transition plate and a common shaft. The profiling roller frame is fixed on the cross beam. The common shaft is arranged at the lower end of the profiling roller frame. The roller brush is arranged in the harvesting plate and is arranged on the common shaft. The transition plate is arranged on the rear side of the harvesting plate. The picking device can be applied to picking fruits on uneven ground and has the advantages of high picking rate and low missed detection rate. Although the floor fruit picking device uses the roller brush to hit the fallen fruits into the harvesting plate, it can prevent damage caused by encountering protruding stones. However, the roller brush always brushes the ground when picking fruits with the forward movement of the frame, which raises a large amount of dust, seriously affecting the working environment, and the roller brush is severely worn and needs to be replaced and repaired frequently. In addition, the bottom of the harvesting plate needs to be close to the ground to make the fallen fruits be hit into the harvesting plate. When the harvesting plate moves to the ground protrusion, the bottom of the harvesting plate will collide with the ground protrusion, and the harvesting plate is prone to deformation and damage.
