Pneumatic bucket rock loading machine

Abstract

The invention discloses a pneumatic bucket rock loading machine. The pneumatic bucket rock loading machine comprises a machine body chassis and a raising bucket system. The raising bucket system comprises a rock loading bucket, a bucket bracket, a raising bucket chain and a raising bucket winding drum. The bucket bracket comprises bucket mounting support arms and semicircular rotary supports, wherein each semicircular rotary support comprises a lever straight-edge portion and an arc rolling portion, and the arc rolling portion of each semicircular rotary support is located on the machine body chassis; a raising bucket cross shaft is arranged on the lever straight-edge portions of the semicircular rotary supports, and the raising bucket chain is arranged between the raising bucket cross shaft and the raising bucket winding drum. The raising bucket system further comprises limiting steel wire ropes, one end of each limiting steel wire rope is fixedly arranged at the front operation end of the machine body chassis, and the other end of each limiting steel wire rope winds across the corresponding semicircular rotary support by one circle and then is fixedly arranged at the rear operation end of the machine body chassis. The pneumatic bucket rock loading machine can be operated in an environment with gas and inflammable gas, and the bucket can be turned over and reset smoothly.

Description

technical field [0001] The invention relates to a pneumatic bucket rock loader, which belongs to the technical field of mine transportation equipment manufacturing. Background technique [0002] The loading equipment of mine horizontal roadway mainly includes scraper, rock loader, electric raking winch, etc. Among them, rock loader is a kind of loading equipment mainly used in mine underground roadway. Excavate and transport to the mine car or conveyor belt or scraper machine to transport to the mine car. Rock loaders in the prior art can be divided into two types from the operating mode: bucket type and rake bucket type; also can be divided into two types from the walking mode: steel wheel track walking rock loader and motor drive crawler loader. rock machine. When the steel wheel track walking rock loader is working, a track should be laid on the working surface, and the rock loader walks on the track and performs loading operations; the motor drives the crawler rock loa...

AI Technical Summary

Problems solved by technology

[0003] First of all, the rock loaders in the prior art are mainly driven by electric power. On the one hand, the electric drive mechanism has a large volume and weight, and the operation intensity and difficulty are relatively large when transported underground by lifting equipment; on the other hand, There are certain safety hazards in the underground operation of the electric drive mechanism, so the application occasions are limited, and it is not suitable for operation in an environment with gas and flammable gas. It is difficult to ensure the safety of underground operations

Secondly, the bucket frame of the rock loader in the prior art is prone to slippage during operation, which makes the bucket easily misplaced, resulting in unsmooth reset, and accelerates the collision wear between the internal components of the rock loader
