Distance adjustable cutting type coal mining device for coal mining

Abstract

The invention provides a distance adjustable cutting type coal mining device for coal mining. The distance adjustable cutting type coal mining device comprises a main body, a rear piece, a support piece, a movable piece, a guiding groove and an adjusting piece; the main body is of rectangular structure; movable wheels are arranged at the bottom corners of the main body; the rear piece is arrangedat the rear end of the main body; the inner bottom of the rear piece is connected with the bottom of the rear end of the main body through a connecting shaft; the support piece is mounted at the top end of the main body; and the bottom of the support piece is connected above a front end plane of the main body through welding. The rear piece is arranged at the rear end of the main body, so that when the distance adjustable cutting type coal mining device is used, a foot of a person can control the rear piece to overturn, the bottom of the external end of the rear piece can be inserted in soil to firmly fix the distance adjustable cutting type coal mining device, the distance adjustable cutting type coal mining device does not move backward even if meeting harder coal, and a cutting piece can steadily mine coal.

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
