Planing and milling wheel control mechanism of a milling machine

Abstract

The invention discloses a planing and milling wheel controlling mechanism for a planing and milling machine. One end of a rod 1 is connected to a rack; the other end of the rod 1 is connected with one end of a rod 2; the other end of the rod 2 is connected with one end of a rod 3 through an axial mobile pair; the other end of the rod 3 is connected to an actuator; one end of a rod 4 is connected to the rack while the other end of the rod 4 is connected with one end of a rod 5 through an axial mobile pair; the other end of the rod 5 is connected to a sliding bush; the sliding bush is mounted at one end of a rod 6 in a sleeving manner; the other end of the rod 6 is connected with one end of a rod 7 through an axial mobile pair; the other end of the rod 7 is connected to the actuator; one end of a rod 9 is connected to the rack while the other end of the rod 9 is connected with one end of a rod 10 through an axial mobile pair; the other end of the rod 10 is connected with one end of a rod 11; one end of a rod 13 is connected to the rack while the other end of the rod 13 is connected with one end of a rod 14 through an axial mobile pair; the other end of the rod 14 is connected to a sliding block; one end of a shaft rod is connected to the rod 10 through an axial mobile pair 21 while the other end of the shaft rod is connected to the rod 14 through an axial mobile pair 22.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a planing and milling wheel control mechanism of a milling machine. Background technique [0002] Road milling machine is one of the main types of asphalt pavement maintenance construction machinery, and also one of the main equipment for asphalt concrete pavement maintenance construction. Defects such as oil waves, textures, and ruts can also be used to excavate pits and grooves on the road surface, as well as roughening of the cement road surface and milling of the surface layer. Because of its high working efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good maneuverability, and the old milling materials can be directly recycled, etc., it is widely used in urban municipal roads and highway maintenance projects. [0003] A general milling machine is composed of an engine, a frame, a milling rotor (planing and milling wheel), a...

AI Technical Summary

Problems solved by technology

The power of the milling depth adjustment device comes from its hydraulic system. Although the hydraulic system has a compact structure, the hydraulic system is easily affected by oil temperature overheating, low mechanical efficiency, poor transmission stability, and poor reliability of the hydraulic system. Maintenance and maintenance are complicated and costly.
