Description
Technical Field
[0001] The utility model relates to the technical field of weed cutting, in particular to a weed cutting device for forestry planting. Background Art
[0002] Forestry planting is an activity of selecting suitable tree species for planting, planting and managing in designated areas and environmental conditions by artificial means. In the process of forestry planting, in order to increase the growth rate of vegetation, it is necessary to regularly cut and clean the branches of the vegetation itself. When using some branch cutting devices for forestry planting, the staff holds the grip of the cutting device, and then applies external force to the grip to lift the cutting part of the device to the corresponding branch bifurcation position, so that the branches are located between the two cutting blades, and then rotates the rotating handle at the end of the grip to make the pull rope drive the active cutting blade relative to the stationary cutting blade The blade rotates and moves, and the cutting surface between the two cutting blades is reduced to cut the branches. However, in the process of cutting the branches in the forestry planting, the cutting blade will move away from the branches due to the cutting reaction force. Therefore, in order to avoid this phenomenon, the staff needs to apply pressing force to the cutting device all the time to make the cutting part fit closely with the branches. However, the staff applies the pressing force on the forestry planting branch cutting device for a long time, which will accelerate the loss of physical strength and needs to be improved. At the same time, the device itself has an integrated pole length structure and cannot be adjusted according to the height of the branches in the forestry planting, which is inconvenient to use.
