Fruit wood shears with bionic blade and differential clamping mechanism

Abstract

The invention discloses a pruner provided with a bionic blade and a differential clamping mechanism. The pruner comprises a blade layer, a middle plate layer and a branch clamping layer, wherein a movable blade, a blade layer plate, a middle layer plate, a branch clamping plate and a movable branch clamping plate are fixedly connected in sequence, and the blade layer plate is tightly connected with the middle layer plate through screws; a handle I and a handle II are fixed between the branch clamping plate and the blade layer plate respectively, the movable blade is hinged with the handle II through a connecting rod I, a connecting rod III is connected with the handle I, the movable branch clamping plate is riveted with a connecting rod II, and the connecting rod II and the connecting rod III are hinged through a round slider screw which is glidingly connected between the branch clamping plate and a cover II; a cylinder compression spring is fixed between the handle I and the handle II through a spring seat, a cylinder torsion spring is arranged in an end groove of the handle II, one end of the cylinder torsion spring is clamped in the groove wall, and the other end is clamped in a groove formed in the middle layer plate. The pruner can clamp a fruit when a branch is cut by the blade, and fruit cutting and picking and branch pruning are realized by a single hand.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a fruit tree shear with a bionic blade and a differential clamping mechanism. Background technique [0002] In the daily management of fruit trees, pruning is one of the essential links. Agronomically, the pruning of fruit trees can make the fruit trees form backbone branches and crowns and maintain a certain structure and shape, so as to achieve the purpose of ensuring high quality, high yield and stable yield of fruit trees. When ordinary fruit tree shears are used for pruning and fruit picking, one hand needs to cut the branches while the other hand needs to catch the fruit to prevent the fruit from falling to the ground and ensure the quality of the fruit. This will reduce labor efficiency and increase the labor of fruit farmers. Therefore, adding a differential clamping device on the basis of ordinary fruit wood shears can reduce the cost while freeing the othe...

AI Technical Summary

Problems solved by technology

Although the existing fruit tree shears (or pruning shears) with clamping mechanism on the market have realized the clamping function, because the clamping part is only simply attached to the blade and moves with the blade, the branches will be cut off, but the The phenomenon that the branch is not clamped; or the phenomenon that the branch is larger than the gap between the clamps and is clamped but cannot be cut

This kind of scissors is generally only suitable for pruning of branches that can be flattened or thinner, and the scope of application is limited
