Title:
MILLING MACHINE TAIL DOOR CONTROL METHOD, MILLING WORKING APPARATUS, AND MILLING MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/178832
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of engineering machinery, and specifically, to a milling machine tail door control method, a milling working apparatus, and a milling machine. The milling machine tail door control method comprises: obtaining milling depth information of a milling rotor of a milling machine; and controlling the working state of a tail door of the milling machine according to the milling depth information. By means of the technical solution of the present disclosure, the working state of the tail door can be adjusted according to the change of the milling depth of the milling rotor, so that when a step-like structure or a raised obstacle is generated on a road surface, the tail door can be controlled to perform a corresponding obstacle avoidance operation, so as to prevent the tail door from being stuck, thus the influence on an engine can be effectively reduced, the fault rate is reduced, the service life is prolonged, and the operation efficiency of the milling machine is improved.
