Automatic pruning device for poplars

Abstract

The invention relates to an automatic pruning device for poplars. The automatic pruning device comprises a climbing mechanism, a rotating mechanism and a pruning saw executing mechanism, wherein the climbing mechanism integrates a driving function and a compression function, wheels are enabled to tightly press the tree trunk, meanwhile, the required motive power is provided for the machine climbing, the rotating mechanism is fixedly arranged at the upper part of the climbing mechanism through a connection support rod, the whole cycle of rotation around the tree trunk is realized, the pruning saw executing mechanism is fixedly arranged on the rotating mechanism, a pruning saw motor and a disk saw realize the feeding in the radial direction under the effect of an electric push rod, the required pruning position is reached, a pruning saw rotates at high speed to realize the sawing along the lateral direction of branches, and the pruning operation is completed. The automatic pruning device for poplars has the advantages that the structure is simple, the operation is convenient, the positioning is accurate, in addition, the automation degree of the pruning is high, the manual direct participation is not needed, and the safety is good. The pruning near the trunk can be realized, the length of small branch piles is favorably reduced, the dead knot is reduced, and the wood quality is improved.

Description

technical field [0001] The invention belongs to the field of forestry machinery, in particular to an automatic pruning device applied to poplar. Background technique [0002] The total area of ​​poplar plantations in my country is more than 7 million hectares, ranking first in the world. With the development and expansion of poplar fast-growing forests, poplar cultivation requires not only fast growth and high yield, but also high-quality timber and high yield. Reasonable and timely pruning can promote the growth of trees, improve the straightness and fullness of trees; at the same time, pruning can also improve the growth environment of trees, such as ventilation and light transmission conditions, reduce pests and diseases, and improve forest fire prevention conditions , increase tree management income. The cost of pruning is high for tall poplar trees. In many areas, there are phenomena such as improper pruning methods or even no pruning. The main reason is that the curr...
