Problems solved by technology

And because the stems of stem and leaf vegetables are weak and fragile, when the clamping force is too large, the stems and leaves will be brittle, and if the clamping force is too small, the vegetables will fall off. Therefore, the suitable range of clamping force for each vegetable is different and relatively Small
Therefore, due to the uneven clamping force of the existing clamping and conveying mechanism, it is difficult to adapt to the workplace where the size of the stem changes greatly, resulting in a high damage rate. Structural adjustment, poor versatility

Embodiment 1

[0031] Such as Figure 2-4 As shown, a clamping and conveying device with approximately equal contact stress, the middle part of the contact part of the closed air bag body 1 and the conveyor belt 2 filled with compressed air in advance is connected as one by glue or other fastening methods; the air bag body 1 and the The clamping belt composed of the conveyor belt 2 surrounds the outer side of the driven roller 3, the support pipe 4 and the driving roller 6 to form a belt conveying mechanism. Two left-right symmetrical airbags injected with compressed air are in contact with each other, and their contact surfaces can generate clamping force on the vegetable stem clamped in the middle. Since the airbag body 1 is made of soft rubber material with extremely low rigidity, the stem The clamping contact stress on the rod is the pressure of the compressed air. Since the airbag body 1 is a closed space, the internal gas pressure will increase under the action of the compression defo...

Abstract

The invention discloses an approximately equal contact stress clamping conveying device. The approximately equal contact stress clamping conveying device comprises a left group of conveying mechanismsand a right group of conveying mechanisms which are arranged symmetrically; each group of the conveying mechanisms comprises a driving roller and a driven roller which are arranged back and forth, and a conveying belt which surrounds outside the driving roller and the driven roller; an airbag body is arranged outside the conveying belt; and compressed air is pre-inflated into the airbag body. According to the approximately equal contact stress clamping conveying device can adapt to a wide range of stem sizes or feeding amounts because of the airbag body has large deformation size, so that theuniversality is improved.

Description

technical field [0001] The invention relates to a vegetable harvesting device, in particular to an approximately equal contact stress clamping and conveying device. Background technique [0002] The orderly harvesting of stem and leaf vegetables generally adopts flexible clamping conveyor belts to complete the orderly collection and transportation of vegetables, such as patents CN201621390378. The flexible conveyor belt runs in the same direction, and the end support roller and the middle floating roller are used to make the conveyor belt produce pre-tension, such as figure 1 , when the vegetable stems are located between two flexible conveyor belts, the conveyor belts are bent and deformed, and the tension of the conveyor belts can exert pressure on the stems to generate clamping force. When the size of the vegetable stems changes, or when the clamping and conveying are at different positions, the angle of bending deformation produced by the flexible belt is different, so ...
