Problems solved by technology

[0003] The existing continuous coal mining machine does not have a mining height display device. Therefore, when the continuous coal mining machine cuts coal by the drum, due to the influence of dust, the driver of the coal mining machine cannot clearly see the exact position of the drum, so it is difficult to ensure that the top and bottom plates smooth
In order to ensure the quality of the project, the coal machine driver often needs to leave or stick his body out of the cab, so there is a big safety hazard

Embodiment Construction

[0014] figure 1 It is a structural schematic diagram of a mining height instrument used for a continuous coal mining machine in an embodiment of the present invention. As shown in the figure, it includes a rack 1, a transmission device 2, and an indicating device 3, wherein the rack is used to be connected to the cutting arm of the continuous coal mining machine; one end of the transmission device is engaged with the rack, and the other end Connect with pointing device. figure 1 Also shows a schematic diagram of the pointing device 3 viewed along the A direction.

[0015] The rack 1 is installed on the cutting arm of the continuous coal mining machine, and the number of teeth and the modulus of the rack 1 are matched with the number of teeth and the modulus of the meshed gears in the transmission device 2 .

[0016] The transmission device 2 can be implemented in various ways according to the actual application situation. In this preferred embodiment, it includes a gear 4 an...

Abstract

The invention discloses a mining height instrument for a continuous miner, which comprises a rack, a transmission gear and an indicating device, wherein the rack is used for connecting to the cutting arm of the continuous miner; and one end of the transmission gear is jointed with the rack and the other end thereof is connected with the indicating device. Adopting the mining height instrument forthe continuous miner of the invention, the driver can definitely know the position of the roller without changing the operating posture or leaving the driving cab under the premise without substantially reforming the miner. Compared with the traditional visual inspection method by the driver, the invention can more accurately determine the height of tunnel.

Description

technical field [0001] The invention relates to a mining height instrument for a continuous coal mining machine. Background technique [0002] The cutting part of the continuous miner is composed of a cutting arm, a drum, and a height-adjusting oil cylinder. The cutting arm is the basis for fixing the drum. Position; the drum rotates on the cutting arm, and picks are installed on the outer circumference of the drum, which are used to cut the coal wall in front to form a roadway. [0003] The existing continuous coal mining machine does not have a mining height display device. Therefore, when the continuous coal mining machine cuts coal by the drum, due to the influence of dust, the driver of the coal mining machine cannot clearly see the exact position of the drum, so it is difficult to ensure that the top and bottom plates smooth. In order to ensure the quality of the project, coal machine drivers often need to leave or stick their bodies out of the cab, so there are grea...
