Description

Technical Field

[0001] The present invention relates to the technical field of mineral vein mining equipment, in particular to a mineral vein mining crushing and transportation device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. According to different types, they are applied to different fields after being processed step by step such as crushing and grinding. In the mining process, ore crushers are needed to crush the ore. Ore crushers can be widely used in many departments such as mining, smelting, building materials, roads, railways, water conservancy and chemical industries.

[0003] A coal crushing device and method for coal mining described in Chinese invention patent application No. 202211029347.X has the ability to remove dust and transport when in use. However, in actual application, the device directly sprays water on the coal, which will cause the crushed coal to stick to each other and easily accumulate in the crushing box, affecting the discharge of materials. In addition, ore fragments will accumulate between the crushing teeth, affecting the particle size of the subsequent ore crushing.

[0004] A crushed stone screening device for mining described in Chinese invention patent application No. 202311285808.4 has the ability to flip the ore when in use, thereby improving the screening effect and preventing accumulation and clogging problems. However, in actual application, the ore will be stuck in the pores of the screen due to vibration, and flipping the ore cannot remove the ore in the pores, and will still clog the screen, resulting in a decrease in screening effect.

[0041] For an embodiment of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 12A mineral vein mining crushing and transportation device includes 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 on the inner side of the bottom bracket 12, and a bottom conveying mechanism located below the screen 36. A dust removal cover 2 is provided on the top of the crushing box 1, a feed hopper 3 is provided on one side of the dust removal cover 2, a dust removal mechanism is provided on the top of the dust removal cover 2, a water tank 5 is provided 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 provided at the bottom of the screen 36.

[0042] A power mechanism is provided at the end of the crushing roller 11, which consists of an active motor 13, an active pulley 14, a driven pulley 15, a transmission belt 16, a gear box 17 and a synchronous gear 18. The active motor 13 is mounted on one side of the bottom bracket 12, and the output end of the active motor 13 is connected to the active pulley 14 through a transmission belt 16. The active pulley 14 is connected to the driven pulley 15 through a transmission belt 16, and the driven pulley 15 is connected to the synchronous gear 18. The synchronous gear 18 is arranged inside the gear box 17, and the gear box 17 is mounted on the outside of the crushing box 1. The synchronous gear 18 is connected to the crushing roller 11 through a transmission belt.

[0043] 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 pipe. The mushroom nozzle 8 is arranged at the center of the dust removal cover 2. An annular collecting groove 9 is opened on the top of the dust removal cover 2. The mushroom nozzle 8 is arranged at the center of the annular collecting groove 9. The annular collecting groove 9 is connected to the water tank 5 through the return pipe 10.

[0044] The vibration mechanism consists of a fixed base 40, a first motor 41 arranged on the fixed base 40, a transmission shaft 42 and an abutment block 43 connected to the first motor 41. The fixed base 40 is installed on the outside of the screen 36, the abutment block 43 is installed on the transmission shaft 42, and the abutment block 43 is arranged below the screen 36. An elastic pad is provided at the connection between the first motor 41 and the fixed base 40.

[0045] The bottom conveying mechanism is composed of a receiving hopper 64 , a transmission auger 65 and an auger power box 66 . A double-shaft motor is provided inside the auger power box 66 , and the ends of the double-shaft motor are transmission-connected to the transmission auger 65 .

[0046] Working process: When in use, ore is poured into the crushing box 1 through the feed hopper 3, and 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. Then, 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, and the dust generated by the crushing floats toward the dust removal cover 2. Under the action of the dust removal mechanism, the water in the water tank 5 is guided into the mushroom nozzle 8 through the pipeline under the action of the water pump 7, so that the mushroom nozzle 8 sprays a hemispherical water curtain. Under the action of the water curtain, the dust generated by the ore crushing can be absorbed. In addition, the water curtain sprayed by the mushroom nozzle 8 is collected in the annular collection trough 9 and then re-introduced into the water tank 5. It can be filtered by the filter element 6 and recycled. After the ore is crushed, it is discharged from the drop port 35 at the bottom of the feed hopper 3 and falls on the screen 36 below the drop port 35. The first motor 41 drives the abutment block 43 to impact the bottom of the screen 36, causing the screen 36 to vibrate, thereby causing the screen 36 to screen the crushed ore. The screened ore 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 enters the other side of the receiving hopper 64. The two parts can be transported to different locations by the transmission auger 65 set in the receiving hopper 64.

[0047] Effect: When in use, when the ore is crushed, the mushroom nozzle 8 can spray a hemispherical water curtain from just above the crushing roller 11, and the water curtain is in continuous flow, driving the surrounding air to flow, so that the ore dust under the water curtain floats upward, and the air flow with dust contacts the water curtain, so that the water curtain adsorbs the dust to prevent the dust from escaping, and has a good dust removal effect. In addition, the bottom conveying mechanism adopts a dual-axis motor setting, which can make the transmission auger 65 move in two directions, realizing separate conveying according to different screening materials, and improving the convenience of use.

[0048] As an embodiment of the present invention, please refer to Figure 2 、 Figure 3 、 Figure 9 and Figure 10A cooling mechanism is provided inside the crushing roller 11. The cooling mechanism is composed of a central water inlet pipe 19 provided at the center of the crushing roller 11, a diverter pipe rack 20 installed on the outer surface of the central water inlet pipe 19, a nozzle 21 installed at the end of the diverter pipe rack 20, and a drain port 75 provided at the edge of the outer wall of the crushing roller 11. The diverter pipe rack 20 is provided with several spring sealing terminals 76 on the central water inlet pipe 19. The spring sealing terminals 76 are installed on the inner wall of the crushing roller 11. A water receiving plate 74 and a top block 77 are provided on the inner wall of the crushing box 1. The water receiving plate 74 is located below the crushing roller 11. A drainage pipe 73 is connected to one side of the water receiving plate 74. A tooth wall cleaning mechanism is provided, which 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 diversion pipe rack 20, a pressure plate 25 installed at the end of the slide rod 24, and a scraper 26 arranged on the surface of the pressure plate 25. The end of the piston 23 is connected to the bottom of the slide rod 24, and 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 passes through the outer surface of the crushing roller 11, and the scraper 26 abuts against the outer wall of the crushing teeth on the crushing roller 11. A rubber plug 27 is provided at the bottom of the slide rod 24, and the outer surface of the rubber plug 27 abuts against the inner wall of the diversion pipe rack 20.

[0049] Working process: When in use, the water inside the water tank 5 is pumped out through the water pump 7, and then introduced into the central water inlet pipe 19 under the guidance of the external pipe. When the crushing roller 11 rotates, the crushing teeth thereon will abut against the tooth wall cleaning mechanism when crushing the ore, causing the pressure plate 25 at the abutment to be squeezed, driving the slide bar 24 connected to the pressure plate 25 to move downward, causing the rubber plug 27 and the piston 23 at the end of the slide bar 24 to move, and the movement of the rubber plug 27 will cause the central water inlet pipe 19 to be connected with the diversion pipe rack 20, so that the water in the central water inlet pipe 19 enters the diversion pipe rack 20, and then is sprayed out from the nozzle 21 at the end of the diversion pipe rack 20 to spray the inner wall of the crushing roller 11, thereby cooling the crushing roller 11. When the crushing roller 11 rotates one circle, The spring sealing terminal 76 of the protruding 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 sealing terminal 76 to retract, thereby separating the spring sealing terminal 76 from the drain port 75, allowing the cooled water to be discharged, and then the discharged water flows onto the water receiving plate 74, and finally discharged from the crushing box 1 through the drain pipe 73 at the end of the water receiving plate 74; and the piston 23 moves toward the inside of the built-in hydraulic cylinder 22, increasing the oil pressure inside the built-in hydraulic cylinder 22, causing the piston 23 at its position to move outward, causing the sliding rod 24 at other positions to move upward, driving the pressure plate 25 at other positions to move upward, causing the scraper 26 installed on the surface of the pressure plate 25 to clean the tooth wall of the crushing tooth, thereby achieving cleaning of the tooth wall of the crushing tooth.

[0050] Effect: When in use, water is sprayed on the inner wall of the crushing roller 11 through the water supply of the water pump 7, so as to cool the crushing roller 11 and prevent the temperature of the crushing teeth of the crushing roller 11 from rising after long-term use, thereby affecting 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, thereby improving the service life of the hydraulic oil in the built-in hydraulic cylinder 22, and the tooth wall cleaning mechanism automatically cleans the tooth wall of the crushing teeth, thereby improving the crushing efficiency and quality.

[0051] As an embodiment of the present invention, please refer to FIG.

The end of the articulated connecting rod 32 is connected to an elastic telescopic rod 33, and the bottom of the elastic telescopic rod 33 is rotatably connected to the second rotating seat 34.

[0052] Working process: When the crushing roller 11 rotates, the surface of its crushing teeth will first abut against the surface of the rotating cleaning brush 30. As the crushing roller 11 rotates, the rotating cleaning brush 30 abuts and rubs against the crushing teeth to clean the ore debris stuck on the surface of the crushing teeth. The rotating cleaning brush 30 swings back and forth left and right under the swing rod 29, the slider 31, the hinged 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, thereby completing the cleaning of the crushing teeth surface.

[0053] Effect: The tooth surface cleaning mechanism can clean the surface of the crushing roller 11, further improving the cleanliness of the crushing roller 11, further enhancing the sharpness of the crushing teeth, and achieving a better crushing effect of the ore.

When the rotating cam 46 rotates, the abutting end 58 at the end of the moving rod 56, which is acted upon by the third abutting spring 57, abuts on the rotating cam 46, so that the moving rod 56 can move back and forth, driving the rotating brush wheel 59 on the moving rod 56 to clean the bottom of the screen 36 within a certain range, thereby preventing the screen 36 from being blocked. In addition, during the reciprocating movement of the moving rod 56, the cylinder 61 can move continuously, so that the air jet holes 60 on the rotating brush wheel 59 can indirectly spray air, further enhancing the cleaning of the screen 36.

[0056] Effect: In actual application, the auxiliary screening mechanism can flip and shake the ore to improve the screening efficiency and screening quality, and the setting of the screen cleaning mechanism can automatically clean the pores of the screen 36 in the area directly below the drop port 35 when in use, to prevent the pores of the screen in this area from being blocked, thereby further improving the screening efficiency.

[0057] 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, and the lifting assembly consists of a slide groove 38 opened on the bottom bracket 12, a connecting plate 37 slidably connected to the slide groove 38, and a first abutting spring 39 arranged between the connecting plate 37 and the slide groove 38. A limiting column is arranged inside the slide groove 38, and the limiting column passes through the connecting plate 37 and is slidably connected to the connecting plate 37. An auxiliary vibration mechanism is provided on the bottom conveying mechanism, and the auxiliary vibration mechanism is arranged below the screen 36. The auxiliary vibration mechanism consists 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 on 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 against the bottom circular top block 72.

[0058] Working process: When a large amount of ore falls from the drop port 35, the screen 36 bears a large weight, so the screen 36 is moved downward by the lifting assembly, so that the bottom of the screen 36 abuts against the top of the impact vibration block 71, and 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 every time it rotates one circle, so that the bottom circular top block 72 moves upward a certain distance, thereby driving the impact vibration block 71 to impact the screen 36 through the lifting rod 70, which can accelerate the vibration frequency and vibration intensity of the screen 36, and further enhance the screening efficiency.

[0059] Effect: When the ore on the screen 36 is large, the screening efficiency of the screen 36 will be affected, so increasing the power source can effectively improve the screening efficiency.
