In conclusion, the tree pruning machine can more efficiently clean branches on a trunk, the service life and the use stability of the blade are improved, and the branch cleaning is more efficient, smooth and tidy.
Preferably, the transmission wheel is an accelerating gear set; this structure can improve the frequency that the sword row popped out, and then improves felling efficiency, can prevent simultaneously that the blade from blocking, guarantees the efficiency of removing the branch.
Preferably, two transmission rods are hinged and symmetrically arranged on each cutting wheel in the center; the two transmission rods are hinged with the two rows of cutter rows in a one-to-one matching manner; the structure can realize that the knife rows are alternatively popped out from the mechanical arm, and the motion states of the knife rows are opposite, so that the mechanical arm is ensured to be always provided with the blades for cutting branches; so as to improve the stability of debranching.
Preferably, the blades are made of permanent magnetic materials, and the magnetic opposite poles of each row of blades are attracted; so as to guarantee two blade in close contact with, effectively prevent the saw-dust card between the sword row, lead to the deformation of blade.
