Adjustable pavement crushing device and using method thereof

Abstract

The invention discloses an adjustable pavement crushing device in the technical field of pavement crushing devices. The adjustable pavement crushing device comprises a vehicle frame, a lifting columnis movably inserted into the right side of the outer wall at the top of a limiting plate, and the annular clamping grooves are both formed at the top and the bottom of the annular outer wall of a sleeve. The outer gear rings are clamped in the annular clamping grooves, at crushing, the telescopic length of an electric telescopic rod is a fixed value, and a screw rod can be rotatably adjusted, andby changing an initial position of the lifting column, the descending depth of the lifting column can be adjusted. During the crushing process, an electric push rod can be started to adjust the heightof a lifting plate, the lifting of the lifting plate can change the ground clearance of the sleeve, and the inner diameter of the sleeve is gradually increased from top to bottom, so that during thedescending process of the sleeve, the distance between the crushing plate and the annular inner wall of the sleeve is gradually decreased, the distance between the crushing teeth arranged at the opposite sides of the sleeve and the crushing plate is also gradually decreased, and because of the reverse rotation directions of a rotating motor and a motor, the two sets of crushing teeth are driven tocrush the stones to different degrees.

Description

technical field [0001] The invention relates to the technical field of pavement crushing devices, in particular to an adjustable pavement crushing device and its usage method. Background technique [0002] When crushing unqualified or damaged road surfaces, workers usually hold a crushing device (a device that drives the milling rotor to rotate for crushing by a motor) to crush the road surface, but the crushed stones are of different sizes, among which large stones Blocks are not conducive to post-processing, and need to be crushed for secondary use, which increases the follow-up workload, and the crushing depth of the road surface needs to be adjusted based on the experience of the operator, and the accuracy is poor. For this reason, we propose a An adjustable pavement breaking device. Contents of the invention [0003] The purpose of the present invention is to provide an adjustable road surface breaking device and its usage method, so as to solve the problems raised i...
