Problems solved by technology

[0004] Theoretically, the more the number of saw blades, the more data will be collected, so the recognition rate will be higher and more accurate. However, the increase in the number of saw blades will increase the force on the recognition device, thereby increasing the complexity and volume of its structure. At the same time, the system processing The burden of data will also increase, resulting in problems such as slow response of the entire system or recognition errors

Embodiment 1

[0041] A fully automatic coal mining machine with coal rock identification function, such as figure 2 , image 3As shown, including a shearer main body 11, a cutting portion, and an auxiliary cutting device, the two ends of the shearer main body 11 are provided with a rocker arm 10, and the rocker arm 10 is connected to the shearer main body 11 through a rocker hydraulic cylinder 14, and the rocker arm 10 is connected to the shearer body 11 through a rocker hydraulic cylinder 14. The upper part of the arm 10 is provided with a cutting part, the cutting part includes a helical blade 2 and a cutting drum 4, the helical blade 2 is connected with the cutting drum 4, the helical blade 2 is connected with one end of the rocker arm 10 through the cutting drum 4, and the helical blade 2 Picks 1 are provided on the edge.

[0042] Auxiliary cutting device comprises two rotating supports, three rotating mechanical arms 6, a cutting support, a telescopic support, such as figure 2 , ...

Embodiment 2

[0045] A fully automatic coal shearer with the function of coal and rock identification, its structure is as described in Embodiment 1, the difference is that a guide rod 20 is provided on the rotating support II 19, a through hole is provided on the telescopic support 27, and the telescopic support 27 Matching connection with the guide rod 20 through the through hole. The expansion and contraction of the first telescopic hydraulic cylinder 22 drives the telescopic bracket 27 to move linearly along the guide rod 20 , and the guide rod 20 is used to provide a movement route and reduce the bearing pressure of the first telescopic hydraulic cylinder.

Embodiment 3

[0047] A fully automatic coal shearer with coal rock identification function, its structure is as described in Embodiment 1, the difference is that the cutting support 29 is provided with a second telescopic hydraulic cylinder 24 and a guide rail 5, such as Figure 5-1 , Figure 5-3 As shown, the output end of the second telescopic hydraulic cylinder 24 is connected to the identification device 33 , and the identification device 33 is arranged on the guide rail 5 . The second telescopic hydraulic cylinder controls the expansion and contraction of the identification device on the guide rail.

Abstract

The invention relates to a full-automatic coal mining machine with a coal rock identification function and a working method of the full-automatic coal mining machine, belongs to the technical field ofcoal rock cutting identification. The full-automatic coal mining machine comprises a coal mining machine main body, a cutting portion and an auxiliary cutting device, wherein the coal mining machinemain body controls the height of the cutting portion through a rocker arm; the cutting portion comprises spiral blades and a cutting drum, and is used for cutting operation; the auxiliary cutting device is arranged on the rocker arm, an identification device cuts and judges a coal rock boundary through cooperation of a rotary support, a rotary mechanical arm, a cutting support and a telescopic support, the lifting operation of the cutting portion is judged through data acquired by the identification device, the full-automatic coal mining machine is suitable for underground coal mining operation under complex working conditions, is high in identification rate, is accurate, and is high in stability, the working environment of workers can be greatly improved, and meanwhile, the coal mining efficiency is also improved.

Description

technical field [0001] The invention relates to a fully automatic coal shearer with a coal rock identification function and a working method thereof, belonging to the technical field of coal rock cutting identification. Background technique [0002] my country's coal demand accounts for nearly 70% of the total energy, which shows that coal consumption is the main force in my country's energy consumption. At present, my country's coal mining has not yet realized automatic mining, especially in coal rock identification, which leads to low efficiency. There is an urgent need for a fully automatic coal mining machine with coal rock identification function. The shearer with coal-rock identification is mainly used in coal mining conditions where the boundary between coal and rock is irregular in shape and there is no clear boundary. [0003] The working principle of coal rock identification is to obtain the force of the saw blade through the saw blade's trial cutting of the coal ...
