Embodiment 1

[0034] refer to Figure 1-9 , a coal shovel with anti-collapse function, including a body 1, a feeding plate 103 and a conveyor belt 109 connected to the body 1, and a cab 603 located on the body 1, and the front end of the body 1 is also connected with a The coal digging plate 102, or the coal digging teeth, the angle of which can be adjusted.

[0035] The function of the feeding board 103 is to automatically transport the coal mined by the coal digging board 102 to the conveyor belt 109 , and then transport it to an external conveyor belt through the conveyor belt 109 for transporting out.

[0036] The conveyor belt 109 is driven by a motor, or a power machine.

[0037] How the feeding plate 103 realizes the automatic transfer of coal to the conveyor belt 109 is explained as follows:

[0038] like figure 1 and 9, the feeding plate 103 is inclined and one end is attached to the ground. At the same time, two sets of first rotating shafts 104 are rotatably connected to the ...

Embodiment 2

[0083] refer to Figure 1-9 , which is basically the same as Example 1. On the basis of Example 1, it is added that the gas in the cab 603 is simultaneously replaced while the coal is broken and whether there are cracks on the top of the tunnel, and the glass of the cab 603 is replaced simultaneously. Cleaning is carried out to ensure the clarity of the operator's field of view.

[0084] Because in the underground tunnel, the environment is relatively harsh, and there is a lot of dust in the air. In order to ensure the health and safety of the operators in the cab 603 of the coal excavator, it is necessary to constantly replace the gas in the cab 603 to improve the fluidity. In addition, due to the large amount of dust, if the glass of the cab 603 is not cleaned, a layer of dust will adhere to it after a period of time, which reduces the clarity of the operator's observation field and makes it inconvenient to accurately operate the shovel.

[0085] like figure 1 , 3 8. In o...

Abstract

The invention discloses a coal mining machine with an anti-collapse function, and belongs to the technical field of coal mining, the coal mining machine with the anti-collapse function comprises a machine body, a feeding plate and a conveying belt which are connected to the machine body, and a cab located on the machine body, and further comprises a driving box and an inclined plate which are fixedly connected to the machine body, the inclined plate is located between the feeding plate and the conveying belt. The second motor is arranged in the driving box, the crushing rod slides on the inner wall of the bottom of the driving box, and when the second motor is started, the crushing rod automatically and periodically gets close to or away from the inclined plate; the second straight movement device is arranged in the driving box; in the mining process, a second motor is started, a knocking rod is driven to crush coal briquettes, meanwhile, a second straight moving device is synchronously driven to horizontally move through a transmission mechanism, different positions of the top of the tunnel are knocked, and the detection range is enlarged.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a coal excavator with an anti-collapse function. Background technique [0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open pit coal mines. With the huge demand for coal in my country, coal mining is becoming more and more frequent. At this time, there are fewer and fewer open-pit coal mines that are relatively easy to mine, and the mining of coal mines is gradually developing to underground coal mines. [0003] The mining of underground coal mines is all carried out underground. A tunnel is carried out underground, and it is automatically mined through a coal excavator. After being broken into small pieces, it is transported to the outside world through a conveyor belt. At this time, the coal excavator is underground. When the tunnel is being mined, the tunnel will get longer ...
