[0003] In a coal mining crushing equipment and method recorded in Chinese invention patent application No. 202211029347.X, the equipment has the ability of dust removal and transfer when in use. However, in actual application, due to directly spraying water on the coal mine, the crushed coal mines will stick to each other, easily accumulate in the crushing box, affecting the discharge, and ore debris will be pressed between the crushing teeth, affecting the particle size of subsequent ore crushing.

[0004] In a gravel screening device for mining recorded in Chinese invention patent application No. 202311285808.4, the device has the ability to flip the ore when in use, improving the screening effect and preventing problems of accumulation and blockage. However, in actual application, due to the ore being stuck in the pores of the screen due to vibration, and flipping the ore cannot remove the ore in the pores, the screen will still be blocked, resulting in a decline in the screening effect.

[0024] An embodiment of the present invention is described with reference to Figure 1 , Figure 2 , Figure 7 and Figure 12, a vein mining, crushing and transporting device, including a crushing box 1, a crushing roller 11 arranged inside the crushing box 1, a bottom bracket 12 located at the bottom of the crushing box 1, a screen 36 installed inside the bottom bracket 12, and a bottom conveying mechanism located below the screen 36. A dust removal cover 2 is arranged at the top of the crushing box 1, a feeding hopper 3 is arranged on one side of the dust removal cover 2, a dust removal mechanism is arranged at the top of the dust removal cover 2, a water tank 5 is arranged on the outer surface of the crushing box 1, the screen 36 is divided into two sections in a stepped shape, and a vibration mechanism is arranged at the bottom of the screen 36.

[0025] A power mechanism is arranged at the end of the crushing roller 11. The power mechanism consists of a main motor 13, a main belt pulley 14, a driven belt pulley 15, a transmission belt 16, a gearbox 17 and a synchronous gear 18. The main motor 13 is installed on one side of the bottom bracket 12. The output end of the main motor 13 is drivingly connected to the main belt pulley 14. The main belt pulley 14 is drivingly connected to the driven belt pulley 15 through the transmission belt 16. The driven belt pulley 15 is drivingly connected to the synchronous gear 18. The synchronous gear 18 is arranged inside the gearbox 17. The gearbox 17 is installed outside the crushing box 1. The synchronous gear 18 is drivingly connected to the crushing roller 11.

[0026] The dust removal mechanism consists of a filter element 6 and a water pump 7 arranged inside the water tank 5, and a mushroom nozzle 8 and a return pipe 10 arranged inside the dust removal cover 2. The drainage end of the water pump 7 is connected to the mushroom nozzle 8 through a pipeline. The mushroom nozzle 8 is arranged at the center of the dust removal cover 2. An annular collection groove 9 is opened at the top of the dust removal cover 2. The mushroom nozzle 8 is arranged at the center of the annular collection groove 9. The annular collection groove 9 is communicated with the water tank 5 through the return pipe 10.

[0027] The vibration mechanism consists of a fixed seat 40, a first motor 41 arranged on the fixed seat 40, a transmission shaft 42 drivingly connected to the first motor 41, and an abutting block 43. The fixed seat 40 is installed outside the screen 36. The abutting block 43 is installed on the transmission shaft 42, and the abutting block 43 is arranged below the screen 36. An elastic pad is arranged at the connection between the first motor 41 and the fixed seat 40.

[0028] The bottom conveying mechanism consists of a receiving hopper 64, a transmission auger 65 and an auger power box 66. A double-shaft motor is arranged inside the auger power box 66. The end of the double-shaft motor is drivingly connected to the transmission auger 65.

[0029] Working process: During use, ore is poured into the interior of the crushing box 1 through the feed hopper 3. Then, the ore pushes the rotating baffle 4 to rotate, thereby opening the feed hopper 3 and allowing the ore to enter the crushing box 1. Next, under the action of the power mechanism, the crushing roller 11 starts to rotate. When the crushing roller 11 rotates, the crushing teeth on its surface squeeze and crush the ore. Among them, the dust generated by crushing drifts towards the dust removal cover 2. Under the action of the dust removal mechanism, the water in the water tank 5 is transported through the pipeline under the action of the water pump 7 and introduced into the mushroom-shaped nozzle 8, causing the mushroom-shaped nozzle 8 to spray a hemispherical water curtain. Under the action of the water curtain, the dust generated by ore crushing can be adsorbed. In addition, the water curtain sprayed by the mushroom-shaped nozzle 8 is collected in the annular collection groove 9 and then re-introduced into the water tank 5, and can be recycled after being filtered by the filter element 6; when the ore is crushed, the ore is discharged from the discharge port 35 at the bottom of the feed hopper 3 and falls on the screen 36 below the discharge port 35. The first motor 41 drives the abutting block 43 to impact the bottom of the screen 36, realizing the vibration of the screen 36, so that the screen 36 screens the crushed ore; the ore after screening is divided into two parts. One part remains above the screen 36 and finally falls from the screen 36 to one side of the receiving hopper 64, while the other part remains below the screen 36 and thus enters the other side of the receiving hopper 64. The transmission auger 65 provided in the receiving hopper 64 can convey the two parts to different positions respectively.

[0030] Achieved effects: During use, when crushing the ore, the mushroom-shaped nozzle 8 can spray a hemispherical water curtain directly above the crushing roller 11, and the water curtain is continuously flowing, driving the surrounding air to flow, causing the ore dust under the water curtain to float upwards, making the airflow with dust contact the water curtain, enabling the water curtain to adsorb the dust and preventing the dust from escaping, having a good dust removal effect. In addition, the bottom conveying mechanism adopts a double-shaft motor setting, which can make the transmission auger 65 move in two directions, realizing separate conveying according to different screened materials, and improving the convenience of use.

[0031] As an implementation manner of the present invention, please refer to Figure 2 、 Figure 3 、 Figure 9 and Figure 10, a cooling mechanism is provided inside the crushing roller 11. The cooling mechanism consists of a central water inlet pipe 19 arranged at the center of the crushing roller 11, a shunt pipe rack 20 installed on the outer surface of the central water inlet pipe 19, a nozzle 21 installed at the end of the shunt pipe rack 20, and a drain port 75 arranged at the edge of the outer sidewall of the crushing roller 11. A number of shunt pipe racks 20 are provided on the central water inlet pipe 19. A spring seal terminal 76 is abutted against the inner side of the drain port 75, and the spring seal terminal 76 is installed on the inner wall of the crushing roller 11. A water receiving plate 74 and a top block 77 are arranged on the inner wall of the crushing box 1. The water receiving plate 74 is located below the crushing roller 11. One side of the water receiving plate 74 is connected with a drain pipe 73. A tooth wall cleaning mechanism is provided on the crushing roller 11. The tooth wall cleaning mechanism consists of a built-in hydraulic cylinder 22 arranged at the center of the central water inlet pipe 19, a piston 23 installed on the built-in hydraulic cylinder 22, a slide rod 24 arranged in the shunt pipe rack 20, a pressing plate 25 installed at the end of the slide rod 24, and a scraping blade 26 arranged on the surface of the pressing plate 25. The end of the piston 23 is connected to the bottom of the slide rod 24. The bottom of the piston 23 is slidably connected to the outer surface of the built-in hydraulic cylinder 22. The end of the slide rod 24 penetrates through the outer surface of the crushing roller 11. The scraping blade 26 abuts against the outer wall of the crushing teeth on the crushing roller 11. A rubber plug 27 is arranged at the bottom of the slide rod 24, and the outer surface of the rubber plug 27 abuts against the inner wall of the shunt pipe rack 20.

[0032] Working process: During use, the water inside the water tank 5 is pumped out by the water pump 7 and then guided into the central water inlet pipe 19 through an external pipe. When the crushing roller 11 rotates, the crushing teeth on it will abut against the tooth wall cleaning mechanism during ore crushing, causing the pressing plate 25 at the abutting position to be squeezed, driving the slide rod 24 connected to the pressing plate 25 to move downward, so that the rubber plug 27 at the end of the slide rod 24 and the piston 23 both move. The movement of the rubber plug 27 will cause the central water inlet pipe 19 to communicate with the shunt pipe rack 20, enabling the water in the central water inlet pipe 19 to enter the shunt pipe rack 20 and then spray out from the nozzle 21 at the end of the shunt pipe rack 20 to spray the inner wall of the crushing roller 11, cooling the crushing roller 11. And when the crushing roller 11 rotates one circle, the spring seal terminal 76 protruding from the drain port 75 on the outer wall of the crushing roller 11 will abut against the top block 77 on the inner wall of the crushing box 1 once, causing the spring seal terminal 76 to retract, so that the spring seal terminal 76 is separated from the drain port 75, enabling the cooled water to be discharged. Then the discharged water flows onto the water receiving plate 74 and finally is discharged from the drain pipe 73 at the end of the water receiving plate 74 out of the crushing box 1; while the piston 23 moves into the built-in hydraulic cylinder 22, increasing the oil pressure inside the built-in hydraulic cylinder 22, causing the piston 23 at this part to move outward, moving the slide rod 24 at other parts upward, driving the pressing plate 25 at other parts to move upward, and enabling the scraping blade 26 installed on the surface of the pressing plate 25 to clean the tooth wall of the crushing teeth, realizing the cleaning of the tooth wall of the crushing teeth.

[0033] Function: During application, water is sprayed onto the inner wall of the crushing roller 11 through the water supply of the water pump 7 to cool the crushing roller 11, preventing the temperature of the crushing teeth from rising after long-term use, which may affect its performance, and improving the service life of the crushing roller 11. Since the built-in hydraulic cylinder 22 is arranged inside the central water inlet pipe 19, the central water inlet pipe 19 can cool the cylinder body of the built-in hydraulic cylinder 22, improving the service life of the hydraulic oil in the built-in hydraulic cylinder 22. The tooth wall cleaning mechanism automatically cleans the tooth walls of the crushing teeth, which can improve the crushing efficiency and quality.

[0034] As an embodiment of the present invention, please refer to FIG. 2 and Figure 5 , a tooth surface cleaning mechanism is arranged on the inner wall of the crushing box 1. The tooth surface cleaning mechanism is composed of a first rotating seat 28 and a second rotating seat 34 installed on the inner wall of the crushing box 1, a swing rod 29 hinged to the first rotating seat 28, and a rotating cleaning brush 30 installed at the end of the swing rod 29. A slider 31 is slidably connected to the swing rod 29. An articulated connecting rod 32 is hinged to the outside of the slider 31. The end of the articulated connecting rod 32 is connected to an elastic telescopic rod 33. The bottom of the elastic telescopic rod 33 is rotatably connected to the second rotating seat 34.

[0035] Working process: When the crushing roller 11 rotates, the surface of its crushing teeth will first contact the surface of the rotating cleaning brush 30. As the crushing roller 11 rotates, the rotating cleaning brush 30 abuts and frictions against the crushing teeth to clean the ore debris adhered to the surface of the crushing teeth. The rotating cleaning brush 30 swings reciprocally under the action of the swing rod 29, the slider 31, the articulated connecting rod 32, the elastic telescopic rod 33, and the second rotating seat 34, so that the rotating cleaning brush 30 always abuts against the crushing teeth on the crushing roller 11 to complete the cleaning of the surface of the crushing teeth.

[0036] Function: The tooth surface cleaning mechanism can clean the surface of the crushing roller 11, further improving the cleanliness of the crushing roller 11, and further enhancing the sharpness of the crushing teeth, resulting in better crushing effect on the ore.

[0037] As an embodiment of the present invention, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8The screen 36 is provided with an auxiliary screening mechanism, which is composed of a second motor 45, a spline shaft 47, a rotating disk 48, a stirring blade 49, a fixed disk 50, a spline sleeve 53 and a second abutting spring 54. The spline shaft 47 is arranged at the segment of the screen 36 and is rotatably connected to the inner wall of the screen 36. The second motor 45 is transmission-connected to the end of the spline shaft 47. The second motor 45 is slidably arranged on the bottom bracket 12. The spline sleeve 53 is sleeved on the spline shaft 47. The stirring blade 49 is installed on the spline shaft. On the outer surface of the key sleeve 53, the rotating disk 48 is installed at the end of the spline sleeve 53, and the rotating disk 48 is slidably arranged with the spline shaft 47. The fixed disk 50 is fixedly installed on the inner wall of the screen 36. The fixed disk 50 and the rotating disk 48 are coaxially arranged. A plurality of flanges 51 are arranged on the outer surface of the fixed disk 50, and abutment balls 52 are arranged on the outer wall of the rotating disk 48; an annular groove is provided on the outer side of the rotating disk 48, and an insert rod 67 is slidably arranged inside the annular groove, and the end of the insert rod 67 is connected to a zigzag swing frame 68. The zigzag swing frame 68 is arranged on the surface of the screen 36; the bottom of the screen 36 is provided with a screen cleaning mechanism, which is composed of a rotating cam 46 connected to the end of the spline shaft 47, a fixed plate 55 fixedly mounted on the outer wall of the screen 36, a moving rod 56 slidably connected to the fixed plate 55, an abutting end 58 mounted on the moving rod 56, a rotating brush wheel 59, and a third abutting spring 57 sleeved on the moving rod 56. The rotating cam 46 abuts against the abutting end 58, and the rotating brush wheel 59 abuts against the moving rod 56. The rod 56 is rotatably connected, and the rotating brush wheel 59 abuts against the bottom surface of the screen 36; a cylinder 61 is fixedly connected to the outer wall of the screen 36, and a piston rod 62 is arranged inside the cylinder 61. The end of the piston rod 62 is connected to an air guide pipe 63, and the end of the piston rod 62 is fixedly connected to the tail of the moving rod 56. A one-way valve is arranged on the cylinder 61 and the piston rod 62. The interior of the rotating brush wheel 59 is hollow, and a plurality of air injection holes 60 are arranged on the surface of the rotating brush wheel 59. The rotating brush wheel 59 is connected to the air guide pipe 63.

[0038] Working process: When in use, the crushed ore falls on the screen 36. In order to screen the ore, the screen 36 is vibrated through a vibration mechanism, so that the ore on the screen 36 slides along the inclined screen 36. In addition, the auxiliary screening mechanism is turned on, so that the second motor 45 drives the spline shaft 47 to rotate. When the spline shaft 47 rotates, the spline sleeve 53 rotates, so that the stirring blades 49 turn over the ore. Under the mutual abutting action of the flanges 51, the abutting balls 52 and the second abutting spring 54 on the fixed disk 50 and the rotating disk 48, the spline sleeve 53 swings reciprocally when rotating, shaking the stirring blades 49 when turning over the ore to move the ore, improving the screening effect. The insertion rod 67 sliding on one side of the rotating disk 48 drives the zigzag swing frame 68 to move reciprocally, so that the zigzag swing frame 68 shakes the ore on the screen 36 left and right, further improving the screening efficiency; when the spline shaft 47 rotates, it drives the rotating cam 46 at its end to rotate. When the rotating cam 46 rotates, the abutting end 58 at the end of the moving rod 56 under the action of the third abutting spring 57 abuts on the rotating cam 46, enabling the moving rod 56 to move reciprocally, driving the rotating brush wheel 59 on the moving rod 56 to clean the bottom of the screen 36 within a certain range, preventing the screen 36 from being blocked. In addition, during the reciprocating movement of the moving rod 56, the air cylinder 61 can continuously move, so that the air jet holes 60 on the rotating brush wheel 59 jet air intermittently, further strengthening the cleaning of the screen 36.

[0039] Achieved effects: In practical applications, the auxiliary screening mechanism can turn over and shake the ore, improving the screening efficiency and quality. The setting of the screen cleaning mechanism can automatically clean the pores of the screen 36 in the area directly below the material falling port 35 during use, preventing the pores of the screen in this area from being blocked, and further improving the screening efficiency.

[0040] As an embodiment of the present invention, please refer to Figure 7 and Figure 11 , a lifting assembly is installed on the outside of the screen 36. The lifting assembly is composed of a chute 38 opened on the bottom bracket 12, a connecting plate 37 slidably connected to the chute 38, and a first abutting spring 39 arranged between the connecting plate 37 and the chute 38. A limiting post is arranged inside the chute 38. The limiting post penetrates through the connecting plate 37 and is slidably connected to the connecting plate 37. An auxiliary vibration mechanism is arranged on the bottom conveying mechanism. The auxiliary vibration mechanism is arranged below the screen 36. The auxiliary vibration mechanism is composed of a fixed bracket 69 installed on the receiving hopper 64, a lifting rod 70 installed inside the fixed bracket 69, an impact vibration block 71 arranged at the top of the lifting rod 70, and a bottom circular top block 72 arranged at the bottom of the lifting rod 70. The edge of the transmission auger 65 abuts on the bottom circular top block 72.

[0041] Working process: When there is a large amount of ore falling from the blanking port 35, the screen 36 bears a relatively large weight, so that the screen 36 moves downward through the lifting assembly, and the bottom of the screen 36 abuts against the top of the impact vibration block 71. Due to the movement of the transmission auger 65, the edge of the transmission auger 65 will abut against the bottom of the bottom circular top block 72 once every revolution, causing the bottom circular top block 72 to move upward a certain distance. Thus, the impact vibration block 71 is driven by the lifting rod 70 to impact the screen 36 once, which can increase the vibration frequency and vibration intensity of the screen 36 and further enhance the screening efficiency.

[0042] Achieved effect: When there is a large amount of ore on the screen 36 during application, it will affect the screening efficiency of the screen 36. Therefore, adding a power source can effectively improve the screening efficiency.
