A vibrating goji berry picking mechanism

Abstract

The invention relates to a vibration-type wolfberry fruit picking mechanism and belongs to the technical field of agricultural machinery. A fixed frame of the mechanism is formed by fixedly connecting door-shaped brackets on the left and right sides, front and rear slide ways and a middle connecting beam; the two sides of the front and rear slide ways, and left and right hoisting opening / closing frames from left and right horizontal movement pair respectively; two opening / closing air cylinders are mounted in the middle of the middle connecting beam; stretching-out piston rod ends of the opening / closing air cylinders are fixedly connected with the left and right hoisting opening / closing frames respectively; each hoisting opening / closing frame is a rectangular framework; front and rear vertical beams, and upper and lower vibration rod mechanisms with opposite vibration directions form vertical movable pairs respectively; a hoisting air cylinder is mounted in the middle of an upper transverse beam; a piston rod end of the hoisting air cylinder is fixedly connected with the vibration rod mechanisms; each vibration rod mechanism comprises horizontal slide rails, and the horizontal slide rails, and upper and lower rows of vibration rod rows form front and rear horizontal movement pairs; the vibration rod rows are in transmission connection with an output shaft mounted on a hydraulic motor. By virtue of the vibration-type wolfberry fruit picking mechanism, the picking efficiency and the picking rate are effectively improved; a needed excitation force is relatively small, and injuries to branches, caused by the picking excitation force, is remarkably reduced.

Description

technical field [0001] The invention relates to a picking mechanism, in particular to a vibrating wolfberry picking mechanism, which belongs to the technical field of agricultural machinery. Background technique [0002] The growth of wolfberry has the characteristics of "disordered inflorescences, continuous flowers and fruits", that is, flowering, fruiting, and maturity occur simultaneously, and the harvesting work is relatively difficult. Picking goji berries by hand is labor-intensive and inefficient. Cyborg picking can easily cause wrist fatigue. [0003] The search found that the Chinese patent application number 201410151606.5 discloses a vibrating wolfberry picking mechanism, which includes a power part, a picking part and a collection part. The power part includes a casing and a motor one arranged in the casing. The power storage device one and the switch, the motor one is connected to the transmission shaft, and the transmission shaft is connected to the picking ...

AI Technical Summary

Problems solved by technology

Because the branches of wolfberry are relatively long, have small stiffness, large deflection, and droop, when the excitation force is applied continuously on one side, the branches of wolfberry are easy to avoid the next excitation force under the action of the previous excitation force, so that the vibrating rod cannot act on the branches and carry out harvesting. Picking, so the picking effect is not ideal. At the same time, the transferability of the force of the fruit-bearing branches is relatively small. In order to make the mature wolfberry fall off, a relatively large excitation force needs to be applied. The result will inevitably damage the fruit-bearing branches, which will affect the subsequent growth of the wolfberry.
