Problems solved by technology

[0004] However, the weight of the pruner is too large, and it is difficult for the staff to hold the pruner
Secondly, the weight of the scissors is relatively large, and the scissors are located on the top of the support bar, so when the branches are trimmed, the support bar is prone to overturning
There are also scissor-type high-branch shears and circular saw-type high-branch shears that are not easy to locate, and the branches are easy to slide

Abstract

The invention relates to the field of fruit tree planting, in particular to a handheld mulberry field shoot harvester which comprises a blade, a connecting column and a handheld rod. The handheld mulberry field shoot harvester is characterized in that the blade is in a half-elliptic shape, an inverted V-shaped cutting edge is arranged in the blade, a connecting portion is provided with at one endof the blade, the connecting portion of the blade is detachably fastened with the upper portion of the connecting column, the other end of the blade is an open free end, and the lower portion of the connecting column is welded with the top of the handheld rod. The shoot harvester has the advantages that the blade with the inverted V-shaped cutting edge solves the problems of difficult positioningof a disc saw blade or a high-branch scissor and sliding of branches, the shoot harvester is simple to operate, good in adaptability and carried with a user, a power supply and an air source are omitted, and trimming requirements of most orchards can be met.

Description

technical field [0001] The invention relates to the field of fruit tree planting, in particular to a hand-held mulberry field cutting machine. Background technique [0002] The mulberry trees in the mulberry garden are generally less than 3 meters in height, and the branches of the mulberry trees need to be pruned every year. During the pruning process, the branches that are too high cannot be reached by hand, and the positions that are too dense are difficult to operate. Working at heights is also very dangerous and the work efficiency is not high. Although there are high branch shears on the market, they are generally cumbersome. Moreover, these scissors usually use an air source or a power source, which is very inconvenient to operate in a mulberry garden. [0003] The Chinese patent with the application number 201420850689.2 published on June 17, 2015 discloses a tree pruner, including a trimmer and a wire puller. The support frame is connected with the third support ...
