Height back adjustable belt cutting saw

Technical field

The utility model relates to pruning branch cutting to be sawed, especially a kind of height back adjustable belt cutting saw that can reduce labour intensity, improve safety and can highly regulate on the spot according to branch.

Background technology

The commodity trees [referring generally to fruit-bearing forest] of prior art all need unnecessary branch to prune away in process of growth, to ensure that commodity trees regulate the reasonable distribution of nutriment, suppress excessive growth, promote flower bud differentiation, reach treelet early flowering result, can extend again full-bloom stage, the full bearing period, also can make veteran rejuvenation.The winter pruning method of commodity trees is mainly divided into three kinds, may be summarized to be and cuts, dredges, removes tiller, the i.e. usually said sanction branch of people.

The sanction branch instrument of prior art generally comprises cuts out secateurs and cutting saw, the general manpower hand held hacksaw that adopts of cutting saw of prior art.When use, orchard worker or workman hold hacksaw and climb, to the sturdy branch place that needs cutting, it is carried out to cutting by the aid such as stair, stool; Or orchard worker climbs fruit tree hacksaw the sturdy branch that needs cutting is carried out to cutting.Be that workman ceaselessly moves commodity trees [fruit tree] in aid or climbing at a sanction branch process need, cause labour intensity large, the center of gravity of workman on aid or fruit tree is difficult to grasp, and is easy to throw from aid or fruit tree, danger coefficient is high, and labour intensity is large.Also have the hand held type electric saw of employing to carry out cutting to sturdy branch, but hand held type electric saw is because saw blade be banded, is easy to occur wrong saw or saws the situation of hindering other branch, its quality is large, when use, orchard worker or workman need aid or the upper commodity trees of climbing, and danger coefficient is high.

In sum, the cutting of prior art saw causes that workman's labour intensity is large and safety coefficient is low.

Summary of the invention

The purpose of this utility model is to provide a kind of height back adjustable belt cutting saw that can reduce labour intensity, improve safety and can highly regulate according to branch on the spot.

For achieving the above object and the technical scheme adopting is such, i.e. a kind of height back adjustable belt cutting saw, comprises the motor with base, is fixed with discoidal saw blade on the output shaft of motor; Wherein:

Described base bottom has been bolted connection supporting member, and this connection supporting member comprises again tube connector, is positioned at tube connector top and outer and stretches out the terminal pad of tube connector outer wall, is provided with connecting hole on terminal pad;

Stay pipe has been threaded in the endoporus of described tube connector, be disposed with at least two adjustable pipes of coupling mutually in the lower end of stay pipe, junction between adjustable pipe is fixed as one by stud, and the junction between adjustable pipe and stay pipe is fixed as one by another stud;

Described motor, by wire and accumulator conducting, is fixed with two braces on the shell of this accumulator.

The utility model is because the advantage that said structure has is: orchard worker or the workman cross cut saw that cuts into two exact halves on ground is assembled, determine the radical that uses adjustable pipe according to branch height, after assembling, orchard worker or workman stand in ground and can carry out branch cutting the commodity trees of higher position, have improved safety when reducing labour intensity.
