Arc-tooth saw type tree remover

Abstract

An arc-tooth saw type tree remover comprises a frame (1), a sawing mechanism (2), a feeding mechanism (3) and a fixing mechanism (4). The arc-tooth saw type tree remover is characterized in that a sawing hydraulic motor (2-2) drives an eccentric shaft (2-12), an arc-tooth saw blade (2-8) is driven to circumferentially reciprocate around its center, and accordingly, a tree is cut; a feeding hydraulic motor (3-1) drives a rotating shaft (2-17) to rotate, the arc-tooth saw blade (2-8) is driven to move by 360 degrees around the central line of the rotating shaft (2-17), and accordingly, the treeis separated from the soil. The arc-tooth saw type tree remover has the advantages that the tree remover is simple in structure and small in size, the labor intensity of nursery stock transplant can be really reduced, the survival rate of nursery stocks can be increased, and mechanized transplanting of the nursery stocks can be realized.

Description

technical field [0001] The invention relates to garden seedling transplanting, which is used for transplanting trees in nurseries and mountainous areas, and belongs to the technical field of forestry machinery. Background technique [0002] At present, the tree transplanting link in domestic nursery stock bases is mainly completed by manpower, but there are problems such as low efficiency, long operation time, and non-standard size of soil balls, especially with the increase of domestic labor costs. Reduce the cost of tree transplanting, so many seedling bases in China hope to have suitable machinery for transplanting trees to replace simple manual operations, so as to overcome the disadvantages of manual transplanting, improve operating efficiency, and reduce transplanting costs. [0003] Although there are various kinds of tree-digging machines on the market, both imported and domestic, and some use shovels, but because the shovels require high-power power, this kind of ma...

AI Technical Summary

Problems solved by technology

[0002] At present, the tree transplanting link in domestic nursery stock bases is mainly completed by manpower, but there are problems such as low efficiency, long operation time, and non-standard size of soil balls, especially with the increase of domestic labor costs. Reduced the cost of tree transplanting, so many seedling bases in China hope to have suitable machinery for transplanting trees to replace simple manual operations, so as to overcome the disadvantages of manual transplanting, improve operating efficiency, and reduce transplanting costs

[0003] Although there are various kinds of tree-digging machines on the market, both imported and domestic, and some use shovels, but because the shovels require high-power power, this kind of machine is very bulky and is not suitable for entering forests with small spacing between trees. Some machines use straight chain saws, but this kind of chain saws can only cut along the sides of the tree. It is difficult to cut the main root of the tree, and manual secondary construction is required.
