Description

Technical Field

[0001] The invention relates to the technical field of fruit picking, in particular to a device for vibrating branches of fruit trees. Background Art

[0002] In the field of fruit picking, using a vibrating device to vibrate branches is a common and efficient method for fruit harvesting. Existing vibrating devices for fruit tree branches are typically equipped with a clamping mechanism and a drive mechanism. The clamping mechanism secures the branch, while the drive mechanism generates vibrations to dislodge the fruit. This improves harvesting efficiency to a certain extent and reduces the labor intensity of manual climbing.

[0003] However, existing shock devices have obvious deficiencies in practical applications. On the one hand, the limit adjustment function of its clamping mechanism is relatively simple, and it is difficult to adapt to branches of different diameters and shapes. Traditional rigid clamping structures often achieve clamping through fixed clamping claws or simple spring mechanisms. For branches with large variations in thickness, it is necessary to frequently replace the clamping claws or perform complex manual adjustments. The operation is cumbersome and time-consuming, resulting in low work efficiency. On the other hand, existing clamping structures mostly use hard materials to directly contact the branches. The bark is easily damaged due to concentrated pressure during the clamping process. Especially for fruit trees with thinner bark such as cherries and apricots, long-term use will affect the normal growth of branches and even lead to the invasion of pests and diseases. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a fruit tree branch shocking device.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a device for vibrating branches of a fruit tree, comprising a handle, the handle being provided with a limiting mechanism for clamping the branches of the fruit tree, and the handle being provided with a driving mechanism for driving the limiting mechanism to vibrate; The limiting mechanism includes a transmission rod, which is slidably connected to one side of the handle, one end of the transmission rod is fixedly connected to a C-shaped sleeve, the upper end of the C-shaped sleeve is provided with a limiting groove, the inner wall of the C-shaped sleeve is rotatably connected to a symmetrically arranged first circular shaft, the upper end of the first circular shaft is fixedly connected to a driving gear, the lower end of the first circular shaft is fixedly connected to a driving pulley, the inner wall of the C-shaped sleeve is fixedly connected to a first limiting belt, a middle side of the first limiting belt is fixedly connected to a traction belt, and the traction belt is fixedly connected to the inner wall of the C-shaped sleeve; The transmission rod is rotatably connected to a second circular shaft near the C-shaped sleeve plate, the upper end of the second circular shaft is fixedly connected to an adjusting gear, the lower end of the second circular shaft is fixedly connected to an adjusting pulley, and the adjusting pulley and the driving pulley are jointly covered with a belt; The limiting mechanism also includes a C-shaped toothed ring, the lower end of the C-shaped toothed ring is fixedly connected to a limiting bar, the limiting bar is slidably connected to the limiting groove, the upper end of the C-shaped toothed ring is fixedly connected to two mounting shafts, and a second limiting belt is fixedly connected between the two mounting shafts.

[0006] Specifically, the limiting mechanism also includes an adjusting component, which includes a limiting sleeve. The limiting sleeve is fixedly connected to the outer wall of the transmission rod. The outer wall of the limiting sleeve is fixedly connected to two limiting blocks, and the two limiting blocks are slidably connected to the transmission shaft.

[0007] Specifically, one end of the transmission shaft is fixedly connected to a rack, and the rack is meshed with the adjusting gear. The other end of the transmission shaft is sleeved with a return spring, one end of the return spring is fixedly connected to the limit block, and the other end of the return spring is fixedly connected to the limit plate, and the limit plate is fixedly connected to the transmission shaft, and a pull ring is fixedly connected to one side of the limit plate.

[0008] Specifically, the driving mechanism includes a transmission chamber, which is fixedly mounted on one side of the handle, a motor is fixedly mounted on the upper end of the transmission chamber, a transmission disc is fixedly connected to the output end of the motor, and an extrusion shaft is fixedly connected to the lower end of the transmission disc.

[0009] Specifically, a transmission plate is slidably connected to the inner wall of the transmission bin, the extrusion shaft is slidably connected to the transmission plate, and the transmission rod is fixedly connected to the transmission plate.

[0010] Specifically, the first limiting belt is arranged in a V-shaped structure under the traction of the traction belt, and the second limiting belt is arranged in a straight-line structure.

[0011] Specifically, the first limiting belt and the second limiting belt are both aramid fiber braided belts, and the widths of the first limiting belt and the second limiting belt are both greater than 2 cm.

[0012] Beneficial effects of the present invention: (1) The present invention provides a slidable transmission rod, adjustment gear, and pulley mechanism for limit adjustment. Simply by pulling the ring, the C-shaped toothed ring can be easily driven to slide along the limit groove, thereby driving the limit belt to clamp branches of different thicknesses. This adjustment method does not require the replacement of parts and can quickly adapt to branches of different diameters within a certain range, greatly simplifying the operation process and improving work efficiency.

[0013] (2) The limiting mechanism of the present invention adopts a first limiting belt and a second limiting belt woven with aramid fiber, which are matched with a C-shaped tooth ring to evenly distribute the clamping force on the surface of the branch. The high strength and flexibility of aramid fiber avoid the stress concentration problem of traditional rigid clamps, significantly reduce the contact pressure, and effectively protect the bark from damage. At the same time, the first limiting belt is V-shaped under the action of the traction belt, and the second limiting belt is a straight-line structure. The cross-limiting of the two forms a stable clamping system, which can not only firmly fix the branch, but also adapt to the irregular surface of the branch through flexible deformation, reduce friction damage during vibration, and provide protection for the long-term healthy growth of fruit trees.
