Positioning and clamping mechanism for vegetable grafted seedlings

Abstract

The invention discloses a positioning and clamping mechanism for vegetable grafted seedlings. It includes multiple convex clamping pieces, and concave clamping pieces with the same number and thickness as the multiple convex clamping pieces; the bottom of the convex clamping piece extends into a triangular intersection with a concave arc; the concave shape After the bottom of the clamping piece is extended, the intersection point of the triangle that is concave is concave arc; the top of the first mounting block is alternately stacked with the same number of concave and convex clamping pieces from bottom to top, and the top of the second mounting block is from The same number of convex and concave clamping pieces as the first mounting block are alternately superimposed from bottom to top; the two mounting blocks are respectively installed on the pneumatic gripper of the pneumatic finger; the pneumatic control system controls the movement of the pneumatic gripper so that the clamping The holding pieces are inserted crosswise to realize the positioning and clamping of the grafted vegetable seedlings. The present invention can realize positioning and clamping and keep the straight line state for different types of grafted seedlings, such as vegetable seedlings and fruit seedlings.

Description

technical field [0001] The invention relates to a gardening and vegetable grafting mechanical mechanism, in particular to a positioning and clamping mechanism for vegetable grafting seedlings. Background technique [0002] Grafting cultivation is the most effective way to overcome the continuous cropping diseases and low temperature obstacles of protected melons and vegetables. Many units at home and abroad have conducted research on mechanized grafting mechanisms and developed a variety of grafting machines. In the process of automatic vegetable grafting, the clamping and positioning of grafted seedlings is an important factor affecting the grafting effect. Especially for the plug-in type (divided into oblique insertion and straight insertion) grafting machines, if the grafted seedlings used as the rootstock are bent during the punching process, the perforating needles will not be able to act accurately relative to the rootstock, and it is easy to be biased, and it is diff...

AI Technical Summary

Problems solved by technology

Especially for the plug-in type (divided into oblique insertion and straight insertion) grafting machines, if the grafted seedlings used as the rootstock are bent during the punching process, the perforating needles will not be able to act accurately relative to the rootstock, and it is easy to be biased, and it is difficult to guarantee the grafted seedlings. The insertion hole of the scion is in a certain correct position, which directly affects the later scion insertion operation

In the grafting mechanisms based on the plugging method developed in China at present, the clamping mechanisms of the rootstock and the scion mostly adopt ordinary air claws, and an opening and closing mechanism is used to clamp the rootstock and the scion, but due to the growth conditions of the grafted seedlings themselves (such as growth bending ), the precise positioning of grafted seedlings during punching and plugging cannot be realized, which affects the success rate of grafting mechanism plugging operations
