Technical Field

[0001] This utility model relates to the field of coal mining machine technology, and in particular to a high-efficiency coal mining machine. Background Technology

[0002] Dust pollution has always been a major challenge hindering the development of the coal mining industry. Traditional coal mining machines generate significant amounts of dust during drilling and other operations. This dust permeates the working environment, severely impairing workers' vision and greatly increasing safety risks. Furthermore, the inhalation of large amounts of dust can cause irreversible damage to workers' health. Moreover, traditional mining machines have very limited dust suppression methods, often relying solely on water spraying from fixed-angle nozzles. This approach is not only ineffective but also wastes water resources. Therefore, we have introduced a new, high-efficiency coal mining machine. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A high-efficiency coal mining machine includes a mining machine body 1, a door 2 located on the upper left side of the mining machine body 1, protective shells 4 located on the upper right front and upper right rear of the mining machine body 1, a spraying device 3 fixedly installed on the upper right middle part of the mining machine body 1, telescopic cylinders 5 fixedly installed inside the two protective shells 4, mounting boxes 6 fixedly installed at the output ends of the two telescopic cylinders 5, a first motor 7 fixedly installed in the middle of the mounting box 6, a rotating rod 8 fixedly installed at the output end of the first motor 7, and a drill bit 9 fixedly installed at the right end of the rotating rod 8.

[0030] In this embodiment, the spraying device 3 includes a water tank 31. A water inlet 32 ​​is provided on the upper left side of the water tank 31. A hydraulic pump 33 is fixedly installed on the upper middle part of the water tank 31 through a connecting pipe. A telescopic hose 34 is fixedly installed on the upper end of the hydraulic pump 33. A water supply horizontal pipe 35 is fixedly installed on the right end of the telescopic hose 34. Five nozzles 36 are fixedly installed on the right end of the water supply horizontal pipe 35 through a connecting pipe. An adjusting device 37 is provided on the lower middle part of the outer surface of the water supply horizontal pipe 35. The nozzles 36 are connected to the inside of the water tank 31 through the water supply horizontal pipe 35, the telescopic hose 34 and the hydraulic pump 33. The adjusting device 37 is fixedly installed on the upper part of the inside of the mounting box 6. The rotating rod 8 passes through the inner right wall of the mounting box 6 and extends to the outside of the mounting box 6.

[0031] The above scheme works as follows: First, water for spraying is injected into the water tank 31 through the inlet 32 ​​on the upper left side. When spraying is required, the hydraulic pump 33 is started, drawing water from the tank 31. The water then passes through the connecting pipe, the hydraulic pump 33, and the telescopic hose 34 before entering the horizontal water supply pipe 35. The water in the horizontal water supply pipe 35 is then transported to the five nozzles 36 through the connecting pipe, and finally sprayed from the nozzles 36 to achieve the spraying operation. Since the nozzles 36 are connected to the inside of the water tank 31 through the horizontal water supply pipe 35, the telescopic hose 34, and the hydraulic pump 33, the smooth delivery of water is ensured.

[0032] In this embodiment, the adjusting device 37 includes a second motor 370, a rotating rod 371 is fixedly installed at the output end of the second motor 370, a universal ball 372 is fixedly installed at the middle of the outer surface of the rotating rod 371, and a connecting rod 373 is fixedly installed at the upper part of the outer surface of the universal ball 372; the connecting rod 373 is fixedly connected to the lower part of the middle of the outer surface of the water supply horizontal pipe 35.

[0033] Through the above scheme: when it is necessary to adjust the spray angle, the second motor 370 in the adjustment device 37 is started. The second motor 370 drives the rotating rod 371 to rotate. When the rotating rod 371 rotates, the universal ball 372 in the middle of its outer surface rotates accordingly. Since the connecting rod 373 is fixedly installed on the upper part of the outer surface of the universal ball 372, and the connecting rod 373 is fixedly connected to the lower part of the middle of the outer surface of the water supply horizontal pipe 35, when the universal ball 372 rotates, it will drive the connecting rod 373 to move, thereby adjusting the angle of the water supply horizontal pipe 35, and finally realizing the adjustment of the spray angle of the nozzle 36.

[0034] It should be noted that this utility model is a high-efficiency coal mining machine. Before the mining machine body 1 performs mining operations in the coal mine, water is first injected into the water tank 31 through the water inlet 32 ​​on the upper left side of the water tank 31. When drilling is required, the telescopic cylinder 5 is activated. The output end of the telescopic cylinder 5 pushes the mounting box 6 to a suitable position. The first motor 7 in the middle of the mounting box 6 is activated. The output end of the first motor 7 drives the rotating rod 8 to rotate. The rotating rod 8 passes through the inner right wall of the mounting box 6 and extends to the outside of the mounting box 6. A drill bit 9 is fixedly installed at the right end of the rotating rod 8. The rotating drill bit 9 performs drilling operations. When spraying is required, the hydraulic pump 33 is activated. The hydraulic pump 33 draws water from the water tank 31. The water passes through the connecting pipe, the hydraulic pump 33, and the telescopic hose 34 in sequence before entering the water tank. Water is supplied through a horizontal water pipe 35, and the water in the horizontal water pipe 35 is then transported to five nozzles 36 through connecting pipes, and finally sprayed out from the nozzles 36. Since the nozzles 36 are connected to the inside of the water tank 31 through the horizontal water pipe 35, the telescopic hose 34 and the hydraulic pump 33, the smooth delivery of water is ensured. At the same time, the adjusting device 37 can adjust the spray angle of the nozzles 36. The second motor 370 in the adjusting device 37 is started, and the second motor 370 drives the rotating rod 371 to rotate. The universal ball 372 on the rotating rod 371 rotates accordingly, which in turn drives the connecting rod 373, which is fixedly connected to the upper part of the outer surface of the universal ball 372, to move. Since the connecting rod 373 is fixedly connected to the lower middle part of the outer surface of the horizontal water pipe 35, the angle of the horizontal water pipe 35 can be adjusted to realize the adjustment of the spray angle of the nozzles 36.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
