A portable forest tending, branching and brush cutting machine

Abstract

The invention discloses a portable forest tending and pruning brush cutter. The portable forest tending and pruning brush cutter comprises a circular saw blade, a saw head, an intermediate transmission rod, a miniature gasoline engine and a handle, wherein a saw head input shaft in the saw head is connected with one end of a transmission shaft in the intermediate transmission rod through a concave and convex type joint; the other end of the transmission shaft in the intermediate transmission rod is also connected with an output shaft of the miniature gasoline engine through the concave and convex type joint; the concave and convex type joint mainly comprises a convex spindle head, a concave spindle head and a sleeve; the convex spindle head is matched with the concave spindle head; one end of the convex spindle head and the saw head input shaft are fixedly connected with each other or are integrally formed in a cutting manner; and two ends of the sleeve are respectively in threaded connection with the saw head and the intermediate transmission rod. The portable forest tending and pruning brush cutter is simple in structure, high in functionality and convenient to carry, and is economical and practical; the length of the body can be increased or decreased at any time according to heights of branches; and requirements on tending and pruning heights of woods at different ages are met.

Description

technical field [0001] The invention belongs to forest management application equipment, in particular to a portable forest tending, branching and bush cutting machine. Background technique [0002] In afforestation production, before afforestation, it is necessary to cut grass, cut and irrigate the forest land, so as to facilitate the afforestation operation and the growth of seedlings. In addition, during the growth process of trees, trees need to be pruned and trimmed timely to promote the growth of trees and obtain a good trunk shape. At the same time, pruning and tending can also reduce the occurrence of dead knots and improve wood quality. Yet at present such as above-mentioned forest tending operations such as weeding, cutting and cutting, also mainly rely on manpower to add machetes to complete. Manual machete debranching operations usually only trim some small branches below 2 meters of the trunk. When performing debranching and tending operations on taller trees, ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the heavy weight of the chain saw head of the pruning machine, in order to ensure the necessary rigidity of the transmission rod, the fuselage cannot be designed too long, so that the length of the whole machine is less than 3 meters. The holding length is about 1 meter (the holding position of the machine is located at the front of the engine), the actual effective working length of the machine is less than 2 meters, so the pruning height is very limited, and it can only be used for the pruning of low landscape trees and flowers in gardens. branch job

[0005] 2. The machine adopts an integrated structure design, the length of the fuselage is fixed, and the length of the fuselage cannot be lengthened or shortened according to actual needs, so the adaptability and flexibility are poor and it is inconvenient to carry, so it is not suitable for use in forest areas

[0006] 3. The machine cannot change the type of saw head according to the needs of the operation, so the type of operation is single, and other forest tending operations such as mowing, shrub cutting, and tip cutting cannot be performed.

[0007] 4. Expensive, high cost of use
