Auxiliary coal charging device of thin seam coal mining machine

Abstract

The invention discloses an auxiliary coal charging device of a thin seam coal mining machine. The device mainly consists of a right coal mining machine rocker arm, a coal plough I, a coal plough II, a coal plough III and a left coal mining machine rocker arm, wherein the coal plough I, the coal plough II and the coal plough III are symmetrically and uniformly distributed below one side of the right coal mining machine rocker arm and one side of the left coal mining machine rocker arm in turn; the coal plough I consists of a steel plate and two reinforcing ribs; the coal plough II consists of a steel plate and four reinforcing ribs; the coal plough III consists of a steel plate and a reinforcing rib; and the coal plough I, the coal plough II and the coal plough III are connected with the right coal mining machine rocker arm and the left coal mining machine rocker arm in a 35-degree mode respectively. The device enhances the coal charging capability of the thin seam coal mining machine only by means of a roller, and particularly enhances the coal charging effect of a slipper riding shovel plate type thin coal mining machine more remarkably; and the device is simple in operation, convenient in use, safe and reliable.

Description

technical field [0001] The invention relates to a coal charging device, in particular to an auxiliary coal charging device for a thin coal shearer. Background technique [0002] At present, the coal loading system of the thin coal shearer first relies on the rotation of the drum to throw the coal onto the scraper machine, and second relies on the forward push of the scraper machine to squeeze the coal into the middle groove. Due to the structure of the thin coal shearer Due to the limitation, the coal passing space between the rocker arm of the shearer and the side of the scraper machine is very small. The floating coal in the coal mining process is deposited on the front of the shearer's sliding shoe, which seriously hinders the forward movement of the shearer. It not only increases the traction resistance, but also easily damages the machinery and equipment. Therefore, it is necessary to install the floating coal in front of the shearer's sliding shoe on the scraper machi...

AI Technical Summary

Problems solved by technology

It not only increases the traction resistance, but also easily damages the machine equipment, so it is necessary to install the floating coal in front of the shearer's sliding shoe on the scraper machine with an auxiliary device, so as to realize the smooth implementation of the thin coal mining process
