Description

Technical Field

[0001] The invention relates to the technical field of pruning, and in particular to a forestry tree trunk processing device and method. Background Art

[0002] After debranching, more nutrients and water can be concentrated on the trunk. The growth of fir trees also depends on apical dominance. Reducing the competition of side branches can make the trunk grow straighter and taller. In the seedling stage of fir trees, removing the lower side branches can increase the growth rate of the trunk by about 20%-30% within a year. Reasonable debranching can reduce the knots in the wood. The knots are the parts where the branches connect to the trunk. Too many knots will reduce the strength and appearance quality of the wood. The wood of the debranched fir trees is more valuable when used in construction, furniture manufacturing and other fields, because the texture of this wood is straighter, the processing performance is better, and it is more in line with the standards of high-quality wood.

[0003] When pruning branches at higher positions, tools such as high branch saws and high branch shears are needed. When using the high branch saw, the operator needs to accurately align the saw blade with the branch and keep the saw blade running stably, which is not easy for the higher branches of fir trees. At the same time, the length of the high branch tools is limited. For particularly tall fir trees, it is still difficult to reach the high branches for effective pruning. For this reason, we propose a forestry trunk processing equipment and method. Summary of the invention

[0013] In addition, the present invention also provides a method for forestry tree trunk processing equipment, comprising the following steps:

[0014] S1. First remove the limit plate from the mounting plate, and then place the mounting plate on the fir tree. Under the tension of the spring, one side of the transmission belt can be pressed against the surface of the fir tree.

[0039] Working principle:

[0040] First, remove the limit plate 8 from the mounting plate 1, and then place the mounting plate 1 on the fir tree. Under the tension of the spring 7, the two mounting plates 1 move relative to each other and drive the connecting plate 9 to rotate, so that the angle between the two connecting plates 9 is reduced, so that one side of the transmission belt 12 is against the surface of the fir tree.

The transmission belt 12 can adaptively clamp on the surface of the fir tree and can adapt to the thickness changes of the fir tree when moving. The branches on the surface of the fir tree are removed by the shovel blade 17 when moving. After trimming the branches on the surface of the fir tree, the staff can control the entire device to move to a suitable position. At this time, the first servo motor 5 is started to drive the threaded rod 4 to rotate, and the threaded rod 4 drives the reciprocating saw 3 to move. The reciprocating saw 3 is started to work and the fir tree is cut while moving. The fir tree can be cut into wood segments of the same length without having to cut down the entire fir tree. At this point, the entire work process ends.
