coal loader

Abstract

The invention discloses a coal loader, which comprises a chassis and a spade opening assembly, wherein the chassis is provided with a front end and a tail end; the tail part of the spade opening assembly is assembled at the front end of the chassis; the spade opening assembly comprises a main spade plate, a turntable assembly, a motor and a baffle plate; the tail part of the main spade plate is used for connecting the spade opening assembly and the chassis; the front part of the main spade plate is used for spading coal so that the coal is loaded onto a spade point arranged on the main spade plate; a main shaft of the turntable assembly is assembled on the middle part of the main spade plate; at least two shifting claws are assembled on the main shaft; each shifting claw is a vortex spiral arm in the rotating direction of the rotating shaft or is of an arc-shaped structure, and is used for picking materials towards one side of the main spade plate; the motor is used for outputting to drive the main shaft; and the baffle plate is arranged at the other side of the main spade plate and is used for blocking materials at the side. The coal loader is applicable to operation at small-cross-section laneways, and the operation reliability of the coal loader is higher.

Description

technical field [0001] The invention relates to a coal charging machine, which belongs to a mining face coal charging machine. Background technique [0002] The main course of coal mining engineering "well and roadway engineering" tells about the section design of the roadway, through reasonable section design, to improve the safety and economic effect of coal mine production. There are two main sections of the roadway, one is a trapezoidal section, and the other is a straight wall semicircular arched section. Generally, the net end face of the roadway is used to characterize the roadway section. Due to the limitation of the size of the coal mining face, the size of the roadway section is considered to be economical and safe. There will be many relatively small-scale roadways, such as a roadway with a clear width of 1.3 meters and a clear height of 0.8 meters. The coal loader cannot enter it, so the coal therein cannot be mined, causing unnecessary waste. [0003] Chinese...

Problems solved by technology

Due to the limitation of the size of the coal mining face, the size of the roadway section is considered to be economical and safe. There will be many relatively small-scale roadways, such as a roadway with a clear width of 1.3 meters and a clear height of 0.8 meters. The coal loader cannot enter it, so the coal in it cannot be mined, causing unnecessary waste

[0003] Chinese patent document CN201165431Y discloses a small coal loader, the coal loader is based on a conveyor belt, and the conveyor belt mechanism to which the conveyor belt belongs is installed on a crawler chassis, wherein the front end of the conveyor belt mechanism is equipped with When the bucket of the material scraper is working, the conveyor belt mechanism must be turned up, which will inevitably occupy a relatively large height space, so the scope of application of the coal loader will be relatively limited

[0007] The coal loader used on some small working faces or small roadways can also be seen in, for example, Chinese patent document CN203716971U. This type of coal loader adopts the structure of a rake bucket and a baffle plate, and is used to rake raw coal into the conveyor. , the rake bucket needs to do reciprocating motion, and the reciprocating motion needs two drivers to drive, the driving structure is more complicated
