Description

Technical Field

[0001] The invention relates to the field of fruit trees, and in particular to a multi-directional adjustable branch and leaf pruning device for fruit trees. Background Art

[0002] Fruit tree pruning refers to adjusting the tree structure of fruit trees, improving the ventilation and light conditions of the tree crown, and promoting the healthy growth of fruit trees through manual pruning. The main purpose of pruning is to regulate the growth potential of fruit trees, improve ventilation and light conditions, and adjust nutrient distribution, thereby ensuring the stable growth of fruit trees and the output of high-quality fruits. Fruit tree pruning is divided into winter pruning and growing season pruning. Winter pruning is generally carried out during the dormant period of fruit trees, when fruit trees grow slowly and pruning causes less damage to fruit trees. Growing season pruning is carried out during the growth period of fruit trees, mainly including spring, summer and autumn pruning.

[0003] At present, in the process of fruit tree cultivation, it is necessary to regularly use pruning devices to prune the cotyledons of fruit trees. Conventional pruning devices mostly use pruning pliers for manual pruning. However, in the face of more complex branch and leaf distribution, it cannot meet the pruning of thicker branches well, and it cannot reasonably adjust the pruning angle according to the alignment of the branches to reduce the difficulty of pruning. Therefore, we make improvements on this and propose a multi-directional adjustable fruit tree branch and leaf pruning device. Summary of the invention

[0004] The object of the present invention is to provide a multi-directional adjustable fruit tree branch and leaf pruning device, which solves the problem that the pruning angle cannot be adjusted according to the distribution direction of branches by setting a driving structure and a connecting structure.

[0011] As a preferred technical solution of the present application, the connection structure also includes an adjustment ring sleeved on the surface of the connecting block and a driving ring threadedly sleeved on the surface of the adjusting ring, an abutment end is fixed at a position corresponding to the bevel groove on the inner side of the adjusting ring, and the driving ring is movably connected to the surface of the connecting column through a bearing, and rotating the driving ring can cause the adjusting ring to slide, so that the pressure plate is pressed tightly against the surface of the pruning saw blade.

[0012] As a preferred technical solution of the present application, the driving structure includes a servo motor fixed inside the installation cavity, a transmission shaft connected to the output end of the servo motor, a rotating disk fixedly installed at the end of the transmission shaft, and an adjustment arm hinged to the surface of the rotating disk;

[0015] As a preferred technical solution of the present application, a convex ring is fixed on the surface of the connecting column, and the convex ring is located on the outside of the housing and is tightly attached to it. The convex ring can be used to limit the connecting column.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. Through the set driving structure, when facing the branches and trunks of different fruit trees, the adjusting motor can be started to make its output end drive the gear to rotate, and the pruning angle of the pruning saw blade can be adjusted in coordination with the rotation of the gear ring, which is convenient for the actual application of the operator;

[0019] 2. Through the setting of the pruning saw blade and the driving structure, the servo motor can be started to drive the rotating shaft to rotate, so that the rotating shaft drives the inner column on the adjusting arm to slide back and forth, thereby promoting the reciprocating motion of the pruning saw blade to achieve the cutting of the branches, thereby facilitating the actual pruning work;

[0020] 3. Through the setting of the connecting structure, the driving ring can be rotated to form a threaded fit with the adjusting ring. The driven adjusting ring will drive the abutment end thereon to move, so that it will come into abutment with the bevel groove. In this way, the pressure plates can be brought closer to each other to clamp the pruning saw blade. Conversely, the two pressure plates can be moved away from each other to facilitate the removal and replacement of the pruning saw blade. BRIEF DESCRIPTION OF THE DRAWINGS
