Description

Technical Field

[0001] The invention relates to an intelligent coal mining machine with an integrated automatic spray dust reduction system and a use method thereof, belonging to the technical field of coal mining equipment. Background Art

[0002] As global energy demand continues to grow, coal remains important as a basic energy source. However, coal mining operations face many challenges, among which dust pollution is one of the problems that needs to be solved urgently. Traditional coal mining machines generate a lot of dust during operation, which not only seriously pollutes the working environment and poses a threat to the health of workers, but also may become a hidden danger of safety accidents such as explosions.

[0003] Although the existing coal mining machines have improved the coal mining efficiency to a certain extent during their design and use, they still have obvious deficiencies in dust control. Traditional dust removal methods, such as manual watering, ventilation, etc., often have poor effects and require a lot of manpower and material resources. At the same time, these traditional methods cannot be adjusted in real time according to the actual working state and dust concentration of the coal mining machine, resulting in unstable dust removal effects, and sometimes even failing to achieve the expected goals. For this reason, the present invention is proposed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an intelligent coal mining machine with an integrated automatic spray dust reduction system. The automatic spray dust reduction system is designed and combined with an intelligent control system to achieve effective control of dust in the coal mining process, while improving the overall performance of the coal mining machine to meet the coal mining industry's needs for efficient, safe and environmentally friendly mining.

[0005] The present invention also provides a method for using the intelligent coal mining machine with integrated automatic spray dust reduction system.

[0006] The technical solution of the present invention is as follows:

[0007] An intelligent coal mining machine with an integrated automatic spray dust suppression system comprises a control system, a cutting part and a traction part, wherein the cutting parts are respectively provided at both ends of the traction part through a movable joint, and the cutting part and the traction part are both connected to the control system;

[0008] The cutting part includes a rocker arm, a roller, a motor and a bracket. The rocker arm is connected to the traction part through a joint. A rotating shaft is arranged at one end of the rocker arm, a roller is arranged at one end of the rotating shaft, and the other end is connected to the motor through a reducer. Cutting teeth are evenly arranged on the outside of the roller, and a number of dust sensors are evenly arranged on the side wall of the roller. A bracket is arranged on the upper side of the rocker arm, and a number of atomizing nozzles are evenly arranged on the lower side of the bracket. The atomizing nozzle is connected to a water tank through a water pipe.

[0009] The traction part, rocker arm and hinge are all commercially available automatic adjustment devices, which are prior art.

[0010] Preferably, according to the present invention, a water spray pipe is provided on the lower side of the rocker arm through an angle adjustment mechanism, the water spray pipe is connected to a water pipeline, and a solenoid valve is provided on the water spray pipe.

[0011] Preferably, according to the present invention, the angle adjustment mechanism includes an adjustment shaft, a rotating motor A and a rotating motor B. One end of the adjustment shaft is connected to a rocker arm through a pin A, and the other end is connected to a water spray pipe through a pin B. The pin A is externally connected to the rotating motor A, and the pin B is externally connected to the rotating motor B. During specific use, the pin A is fixedly connected to the adjustment shaft and movably connected to the rocker arm through an outer sleeve. When the motor A drives the pin to rotate, the adjustment shaft rotates synchronously. The pin B is connected in the same way. The rotating motor A and the rotating motor B are used to drive the pin A and the pin B to rotate respectively, thereby realizing the height and angle adjustment of the water spray pipe.

[0012] Preferably according to the present invention, a booster pump is provided on the water pipeline to increase the water flow pressure.

[0013] Preferably, according to the present invention, a plurality of lighting lamps are arranged on the lower side of the bracket to facilitate observation.

[0014] Preferably according to the present invention, the material of the roller and the rocker arm is alloy steel, and the strength, hardness and wear resistance of the steel are improved by adding alloy elements (such as chromium, molybdenum, nickel, etc.).

[0015] The method for using the intelligent coal mining machine with integrated automatic spray dust suppression system is as follows:

[0016] (1) The traction unit moves to the position where the coal seam is to be mined, the cutting unit starts, and the motor drives the drum to rotate to cut the coal seam;

[0017] (2) During coal mining, the dust sensor detects the dust concentration. When it is detected that the overall dust concentration exceeds the set value, the atomizing nozzle is opened and the booster pump is started to perform atomization and dust reduction;

[0018] (3) During atomization dust reduction, if the dust sensor detects that dust is concentrated in a certain area and exceeds the threshold, the angle adjustment mechanism is used to adjust the water spray pipe so that the water outlet is aimed at the dust concentration area, and then the solenoid valve is opened to spray water to achieve rapid dust reduction.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention designs an automatic spray dust reduction system, uses a nozzle to achieve large-area atomization dust reduction, uses a water spray pipe to spray water on dust concentrated areas, uses a large flow rate to achieve rapid dust reduction, and combines with an intelligent control system to achieve effective control of dust in the coal mining process, while improving the overall performance of the coal mining machine to meet the coal mining industry's needs for efficient, safe, and environmentally friendly mining.

[0021] 2. The present invention installs the water spray pipe on the rocker arm so that the water spray pipe and the rocker arm are linked. The dust concentration area is mainly concentrated in the drum coal mining area. The water spray pipe and the rocker arm are linked to ensure that the water spray pipe can always point to the dust concentration area. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings, but is not limited thereto.

[0027] Embodiment 1:

[0028] like Figure 1-2 As shown, this embodiment provides an intelligent coal mining machine with an integrated automatic spray dust suppression system, including a control system, a cutting part 1 and a traction part 2, wherein the cutting part 1 is provided at both ends of the traction part 2 through a live joint 3, and the cutting part 1 and the traction part 2 are both connected to a control system;

[0029] The cutting part 1 includes a rocker arm 11, a roller 12, a motor and a bracket 13. The rocker arm 11 is connected to the traction part through a joint 3. A rotating shaft is arranged at one end of the rocker arm 11, a roller 12 is arranged at one end of the rotating shaft, and the other end is connected to the motor through a reducer. Cutting teeth are evenly arranged on the outside of the roller, and a number of dust sensors 14 are evenly arranged on the side wall of the roller 12 to monitor the operating status of the coal mining machine and the dust generated around it in real time. A bracket 13 is arranged on the upper side of the rocker arm 11, and a number of atomizing nozzles 15 are evenly arranged on the lower side of the bracket 13. The atomizing nozzle 15 is connected to a water storage tank 16 through a water pipe.

[0030] The cutting part is the core working mechanism of the coal mining machine. It is mainly responsible for completing the tasks of dropping and loading coal, reducing the speed of the motor to the speed required by the drum, and driving the cutting teeth on the drum to break the coal on the coal wall. The work of the cutting part directly affects the production efficiency of the coal mining machine and the quality of coal mining.

[0031] The main function of the traction unit is to move the coal mining machine so that the cutting unit can cut into the coal wall to drop coal or perform other necessary adjustments. The traction unit 2, rocker arm 11 and articulation 3 are all commercially available automatic adjustment devices, which are existing technologies. The traction unit can select MG300 / 700-AWD traction unit or MG500 / 1200-WD series traction unit according to different geological conditions. The figure shows a partial traction unit structure, and the lower part is provided with a sliding shoe, a walking wheel and other mechanisms.

[0032] The sliding shoe plays a supporting and guiding role. The sliding shoe is usually made of high-strength and wear-resistant materials to cope with harsh working environments and high-intensity usage requirements. The walking wheel works with the sliding shoe to realize the movement of the coal mining machine.

[0033] The traction unit is also equipped with an overload protection device, which is an existing circuit protection component. When the coal mining machine is subjected to an overload shock or the load exceeds the rated value, it can quickly cut off the power supply to protect the motor and other key components from damage.

[0034] The right cutting part in the figure has the same structure as the left cutting part, both of which are equipped with a rocker arm. In order to avoid looking cumbersome, the right cutting part is not marked in the figure.

[0035] A water spray pipe 18 is provided at the lower side of the rocker arm 11 through an angle adjustment mechanism 19 . The water spray pipe 18 is connected to a water pipeline, and a solenoid valve is provided on the water spray pipe 18 .

[0036] The angle adjustment mechanism 19 includes an adjustment shaft, a rotating motor A and a rotating motor B. One end of the adjustment shaft is connected to a rocker arm through a pin A, and the other end is connected to a water spray pipe through a pin B. The pin A is externally connected to the rotating motor A, and the pin B is externally connected to the rotating motor B. During specific use, the pin A is fixedly connected to the adjustment shaft and movably connected to the rocker arm through an outer sleeve. When the motor A drives the pin to rotate, the adjustment shaft rotates synchronously. The pin B is connected in the same way. The rotating motor A and the rotating motor B are used to drive the pin A and the pin B to rotate respectively, thereby realizing the height and angle adjustment of the water spray pipe.

[0037] A booster pump is provided on the water pipeline to increase the water flow pressure.

[0038] A plurality of lighting lamps 17 are provided on the lower side of the bracket 13 for easy observation.

[0039] The material of the roller 12 and the rocker arm 11 is alloy steel, and the strength, hardness and wear resistance of the steel are improved by adding alloy elements (such as chromium, molybdenum, nickel, etc.).

[0040] The method for using the intelligent coal mining machine with integrated automatic spray dust suppression system is as follows:

[0041] (1) The traction unit 2 moves to the position where the coal seam is to be mined, the cutting unit 1 is started, and the motor drives the drum 12 to rotate to cut the coal seam;

[0042] (2) During coal mining, the dust sensor 14 detects the dust concentration. When it is detected that the overall dust concentration exceeds the set value, the atomizing nozzle 15 is turned on and the booster pump is started to perform atomization and dust reduction;

[0043] (3) During atomization dust reduction, if the dust sensor 14 detects that dust is concentrated in a certain area and exceeds a threshold, the angle adjustment mechanism 19 is used to adjust the water spray pipe so that the water outlet is aimed at the dust concentration area, and then the solenoid valve is opened to spray water to achieve rapid dust reduction.

[0044] The above descriptions are only preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be considered as within the protection scope of the present invention.
