Fruit tree pruning device

Abstract

The invention discloses a fruit tree pruning device, and relates to the technical field of agricultural machinery. The fruit tree pruning device is characterized in that a small arm is connected with the tail end of a mechanical arm, a rotating part is rotationally connected to the end, away from the mechanical arm, of the small arm, a first driving mechanism is used for driving the rotating part to rotate relative to the small arm, a shaft rod is rotationally connected to the rotating part, the axial direction of the shaft rod is perpendicular to the axial direction of the rotating part rotating relative to the small arm, a cutting-off assembly is arranged on the shaft rod and comprises a saw blade, a second driving mechanism is used for driving the shaft rod to rotate relative to the rotating part, an anti-adhesion assembly comprises two parallel strip rods, the two strip rods are fixedly connected to the rotating part, and a cutting-off groove is formed between the two strip rods. The cutting-off assembly and the shaft rod can be driven to rotate on the rotating part through the second driving mechanism, branches can be conveniently and thoroughly cut off in cooperation with the anti-adhesion assembly, the cut branches are thoroughly separated from a parent body and fall down, and therefore, illumination, growth vigor and fruiting of fruit trees can be facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a fruit tree pruning device. Background technique [0002] The pruning of fruit trees is an important link in the production of various fruits. It is related to the growth of trees, the yield and quality of fruits. For example, the trellis-shaped planting mode of pear trees requires pruning off the upper branches (leggy branches) of pear trees. , to decapitate the secondary molecules and the tops of the current year's branches can achieve the purpose of optimizing the structure of the tree, improving care, balancing the growth of the tree, and promoting the transformation from vegetative growth to reproductive growth. At present, the mechanization level of domestic orchards is relatively low, and cannot keep up with the development needs of the forestry and fruit industry. There is a lack of supporting equipment for fruit tree pruning, fertilization, spraying and o...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, pruning is generally performed by special pruning scissors, which is time-consuming and laborious. Part of it is to use a chainsaw to cut off. Although the efficiency has been improved, on the one hand, the movement of the chainsaw between the branches is not flexible enough. On the other hand, the branches After being cut off by a chainsaw, it is common for the branch to be cut incompletely, that is, the branch to be cut falls down due to gravity after being cut off, but it is still connected to the parent body through its bark and phloem. After research and comparative experiments, it is found that These severed branches cannot be completely separated from the parent body, and still affect the light, growth of fruit trees and fruiting, etc.
