Crank slider type forestry trimming head

Abstract

The invention relates to a crank slider type forestry trimming head which mainly solves the technical problem that an existing cutting head is good in cutting effect and high in manufacturing cost. According to the technical scheme, the crank slider type forestry trimming head comprises a fixed cutting blade, a movable cutting blade, a tool apron, a spline shaft, a motor, a transparent cover, a roller bearing, a slide plate, a rotating plate, a rotating plate blocking cover, a bearing slider, copper plates, a slide guiding plate, a cushion block, a plug, a connecting seat, a blocking cover anda pin. The fixed cutting blade and the slide guiding plate are fixed to a cutting blade supporting plate of the tool apron. The movable cutting blade is arranged between the fixed cutting blade and the cutting blade supporting plate. The copper plates are fixed to the upper edge and the lower edge of the cutting blade supporting plate. The slide plate is fixed to the middle of a non-cutting faceof the movable cutting blade. A bearing of the bearing slider is arranged in a slide guiding groove of the slide plate. The roller bearing is arranged at the front end of the spline shaft. The splineshaft and the roller bearing are arranged in a power bin of the tool apron. The spline end of the spline shaft is arranged in a shaft hole of the motor. The motor is fixed to a rear supporting plate of the tool apron.

Description

technical field [0001] The invention relates to a crank slider type forestry pruning head, which belongs to the technical field of forestry machinery used for tree twig pruning and shrub stubble cutting. Background technique [0002] The forestry pruning head that is used for tree twig pruning and shrub stubble mainly contains two types at present, and a class is a rotary disc saw blade type, and another kind is a reciprocating double-knife shearing type. The efficiency of trimming thick twigs with the rotating circular saw blade pruning head is low; when it is used for shrub stubble, the long section of the cut is easy to be broken, which affects the germination rate of shrubs after stubble. The reciprocating double-knife shearing trimming head currently has two structures, one is the crank-link type driven by a hydraulic motor or an electric motor, and the other is the oil cylinder reciprocating type. Among them, the crank-link type trimming head driven by a hydraulic mot...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problems of poor shearing effect and high cost of the existing shearing head, and provide an economical and applicable slider crank type that can cut thicker branches and shrubs with a diameter of 100 mm or more and has a good shearing effect.
