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.
