An adjustable distance cutting coal cutting device for coal mining

Abstract

The invention provides an adjustable distance cutting type coal cutting device for coal mining, comprising: a main body, a rear part, a support part, a moving part, a guide groove and an adjusting part; the main body is a rectangular structure, and the bottom edge of the main body The angular position is provided with moving wheels; the rear part is arranged at the rear end of the main body, and the inner bottom of the rear part is connected with the rear end bottom of the main body through a connecting shaft; the support part is installed on the top of the main body, and the support part The bottom is connected above the front plane of the main body by welding; the rear part is used to be located at the rear end of the main body, so that when the device needs to be used, the rear part can be turned over by manpower using the foot control, so that the rear part The bottom of the outer end can be inserted into the soil, so that the device can be firmly fixed, so that even when the device encounters relatively hard coal, it will not move backwards, so that the cutting piece can be stably opened.

Description

technical field [0001] The invention belongs to the technical field of coal mining equipment, and more specifically relates to an adjustable distance cutting type coal cutting device for coal mining. Background technique [0002] When coal mines are mined, devices are usually required, while in layered mining, distance-adjustable cutting coal devices are usually required. [0003] For example, the application number: CN201510020432.3 relates to a coal mining device, including a motor traction part and a deceleration mechanism. There is a hydraulic transmission device and a spray cooling device, and the running parts are fixed at the lower end of the frame. The output shaft of the motor installed on the frame is connected to the transmission sprocket through a gear reduction device, and the sprocket is connected to the pin rail fixed on the conveyor on the working surface Mesh. [0004] Based on the findings of the prior art, when the existing distance-adjustable coal cutti...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an adjustable-distance cutting coal cutting device for coal mining, to solve the problem that the existing distance-adjustable cutting coal cutting device encounters relatively hard coal when it is in use. At that time, the coal cutting device could not cut the coal conveniently, and it was easy to generate a backward driving force, which led to the overall instability of the equipment. Moreover, when the existing distance-adjustable cutting coal cutting device was in use, it usually could only adjust the distance and could not be added according to the demand. With an appropriate number of cutting heads, it is impossible to simultaneously control multiple cutting heads for simultaneous mining, thus failing to improve work efficiency
