Problems solved by technology

[0002] Most of the existing improvements to coal shearers in our country are carried out in terms of traction and working knives. For coal seams with different hardness, the way of replacing working knives is adopted, which reduces the working efficiency when encountering different coal seams, and requires shutdown to replace working knives.

Abstract

The invention discloses an improved coal cutter. The improved coal cutter comprises rollers and a machine body. The rollers are located at the front end and the rear end of the machine body and connected to the machine body through supporting arms. The machine body is provided with hydraulic cylinders to control the lifting heights of the supporting arms. Force sensors are arranged in oil ways of the hydraulic cylinders and located in the machine body. Baffles are arranged between the rollers and the supporting arms. Blowholes are formed in the baffles. The baffles can swing in a certain angle range, and power is provided by gears located at the tail ends of stepping motors on the supporting arms. Driving motors at the tail ends of the supporting arms drive gearboxes to provide power for the rollers. A control cabinet and an air pump are arranged in the middle of the machine body. The control cabinet controls the operation process of the whole coal cutter and outputs control signals to motor achieving advancing and retracting. The coal cutter is reasonable in improvement.

Description

technical field [0001] The invention relates to an improved coal shearer, the main idea is to measure the hardness of different coal seams in mining by adding a force sensor to the oil circuit of the hydraulic cylinder acting on the roller arm, and then add it to the control box A speed change device is used to realize the change of speed, and the combination of the two makes coal mining more efficient. Background technique [0002] Most of the existing improvements to coal shearers in our country are carried out in terms of traction and working knives. For coal seams with different hardness, the way of replacing working knives is adopted, so that the working efficiency is reduced when encountering different coal seams, and it is necessary to stop work to replace the working knives. Contents of the invention [0003] The present invention provides the following technical solutions: an improved coal mining machine, including a drum and a fuselage, characterized in that ther...
