Hydraulic drilling rig primary filter linkage slag discharge device

Abstract

The invention discloses a hydraulic drill rig coarse filter linked slag discharge device, a chain guide wheel shaft is arranged on a propelling beam, and is in rigid connection with the propelling beam, a chain guide wheel is arranged on the chain guide wheel shaft, a chain is meshed with the chain guide wheel, a thread distributed on the chain guide wheel shaft is meshed with a thread on the inner side of the chain guide wheel, a coarse filter is connected with the a coarse filter swing arm, the coarse filter swing arm is installed on a coarse filter shaft seat by a swing arm pin, the coarse filter shaft seat is installed on the propelling beam, the end of the coarse filter swing arm is provided with a shifting fork, and the shifting fork contacts the chain guide wheel. The hydraulic drill rig coarse filter linked slag discharge device solves the problem of too high dust accumulation caused by incapability of swing of the coarse filter by better use of reciprocating movement of the chain to realize linkage of the swing of the coarse filter and the movement of the chain, and the hydraulic drill rig coarse filter linked slag discharge device has the advantages of being simple in structure, stable and reliable, and requires no external power and control device.

Description

technical field [0001] The invention relates to the field of construction machinery mechanisms, in particular to a linkage slag discharge device for a coarse filter of a hydraulic drilling rig. Background technique [0002] During the working process of the coarse filter of the hydraulic rock drilling rig, since the coarse filter will discharge a large amount of crushed stone with large particles, the crushed stone will accumulate under the coarse filter, causing the outlet of the coarse filter to be blocked, and the drill arm of the drilling rig cannot work when it is working. To move, there needs to be a mechanism that links the strainer with the working part of the drill arm, so that the falling gravel is no longer accumulated and does not affect the work of the strainer. SUMMARY OF THE INVENTION [0003] In view of the above existing problems, the purpose of the present invention is to provide a linkage slag discharge device for the coarse filter of a hydraulic drillin...

AI Technical Summary

Problems solved by technology

[0005] Beneficial effects of the present invention: the present invention makes better use of the reciprocating motion of the chain so that the swing of the coarse filter can be linked with the movement of the chain, solving the problem of excessive dust accumulation caused by the inability of the coarse filter to swing, and the structure is simple, stable and reliable , without external power and control devices
