Problems solved by technology

When working, the working mechanism swings up and down and left and right to gradually complete the crushing of the full-section coal and rock. However, when the working mechanism is working so far, the cutting area is relatively small, and lateral force will be generated when the working mechanism is swinging and cutting.

Embodiment 1

[0048] A new type of roadheader cutting device, such as Figure 1-8 As shown, it includes a main body 10, a supporting driving device 4 and an adjusting hydraulic cylinder 8, the main body 10 is fixedly connected with the supporting driving device 4, and the main body 10 is provided with a sprocket 1, a chain 2 and a scraper 11;

[0049] The supporting driving device 4 is located at one end of the body 10, and is provided with a motor 5 and a reducer 9, the output shaft of the motor 5 is connected with the input shaft of the reducer 9, the output shaft of the reducer 9 is connected with the sprocket 1, and the sprocket 1 is connected with the sprocket 1. The chain 2 meshes and drives the rotation of the chain 2. The chain 2 is provided with a plurality of scrapers 11, and the scraper 11 is provided with picks 12 for cutting;

[0050] One end of the supporting driving device 4 is connected with the connecting ear plate 6 on the upper part of the car body of the roadheader 7 thr...

Embodiment 2

[0055] A new type of roadheader cutting device, the structure of which is shown in Embodiment 1, the difference is that the number of adjustment hydraulic cylinders 8 is two, which are respectively located on both sides of the support drive device 4 and the roadheader 7, and the two adjustment hydraulic cylinders The cylinder expands and contracts at the same time to adjust the angle between the body and the horizontal plane, which improves the stability of the adjustment process.

Embodiment 3

[0057] A new roadheader cutting device, the structure of which is shown in Embodiment 2, the difference is that the upper and lower surfaces of the body 10 are provided with nozzles 3 for removing dust when cutting coal and rocks, and there are multiple nozzles 3, preferably The upper surface and the lower surface of the main body are provided with 12 nozzles, and a water supply pipe is provided inside the main body 10. The water supply pipe is connected with the nozzle 3 to provide water for the nozzle 3. The source of the water in the water supply pipe is the same as that of an ordinary roadheader. unanimous.

Abstract

The invention relates to a novel heading machine cutting device and a working method thereof, and belongs to the field of coal rock crushing of a heading roadway of a stope face. The novel heading machine cutting device comprises a body, a support driving device and an adjusting hydraulic cylinder; the body is provided with a chain wheel, a chain and a scraper; a motor and a speed reducer are arranged in the support driving device; an output shaft of the speed reducer is connected with the chain wheel; the chain wheel is meshed with the chain and drives the chain to rotate; the multiple scrapers are arranged on the chain; cutting teeth for cutting are arranged on the scrapers; one end of the support driving device is rotationally connected with a connecting lug plate at the upper part of a vehicle body of a heading machine through a pin shaft; the other end of the support driving device is connected with the lower part of the heading machine through the adjusting hydraulic cylinder; the upper surface, the lower surface and the end, away from the support driving device, of the body are all working faces; and the ratio of the length to the width of the body is 2:1-3:1. According to the novel heading machine cutting device and the working method thereof, coal rock can be cut by adopting various angles and various cutting areas, so that the cutting area is large, and the purpose of rapidly tunneling a roadway can be achieved.

Description

technical field [0001] The invention relates to a novel roadheader cutting device and a working method thereof, which belong to the field of coal and rock crushing in excavation roadways of mining working faces. Background technique [0002] With the continuous improvement of the mechanization level of the coal mining face, the speed of coal mining is also accelerating, and the roadway excavation and the preparation of the coal mining face must also be accelerated accordingly. Only relying on the drilling and blasting method to manufacture the roadway can no longer meet the current coal mining requirements. It is an effective measure to increase the speed of excavation. Compared with the drilling and blasting method, the excavation machine has the advantages of fast speed, low cost and low cost. Good safety, conducive to the preparation of coal mining face, small amount of work, good working conditions and other advantages; [0003] Partial section tunnel boring machine is ...
