Description

Technical Field

[0001] This invention relates to the technical field of ore transportation, and more particularly to a gangue transfer device for coal mining. Background Technology

[0002] Coal has a very complex composition, typically consisting of organic matter, minerals, and gases. During coal formation, organic matter undergoes biochemical reactions under high temperature and pressure, gradually transforming into coal. Minerals are distributed around the organic matter particles, forming the ash in coal. Because minerals and organic matter are mixed together during coal geological formation, the rocks, sandstone, mudstone, etc., existing above, below, and at the boundaries of coal seams are collectively referred to as gangue. Gangue is waste rock produced during coal mining, and its ash and other components are similar to those of the main coal seam.

[0003] To reduce the impact of large-scale gangue accumulation on underground production, gangue is transported through a conveying device during mining. To prevent material spillage and injury, and to reduce dust spread, the conveying device transports the gangue to a buffer hopper. After passing through the buffer hopper, the gangue falls into the mine car, which then transports it out. However, excessively heavy gangue falling directly into the mine car can cause significant impact and affect its use. Summary of the Invention

[0041] Example 1

[0042] Reference Figures 1-2 A coal mine gangue transfer device is provided, comprising: a hopper 100 with a feed inlet 101 on one side and a discharge outlet 102 at the bottom; and a screening component 200, including a support assembly 201 located below the feed inlet 101 and a screening section 202 located in the hopper 100; wherein the support assembly 201 corresponds to the screening section 202.

[0043] A feed inlet 101 is opened on one side of the hopper 100. The feed inlet 101 corresponds to the conveying device, so that the gangue can be directly conveyed into the hopper 100 by the conveying device. A discharge outlet 102 is opened at the bottom of the hopper 100. The gangue in the hopper 100 is discharged from the discharge outlet 102 and falls into the mine car. A fan-shaped discharge gate can be installed below the discharge outlet 102. A hydraulic cylinder is installed on one side of the gate in the direction of movement. The extension and retraction of the hydraulic cylinder is reasonably controlled according to the amount of gangue. At the same time, when the amount of gangue is large, the discharge speed is controlled to prevent the material from spilling due to the mine car not pulling in time.

[0044] The screening component 200 is located in the hopper 100. The support component 201 corresponds to the ground of the feed inlet 101. The screening section 202 is located on the support component 201. The support component 201 can support the screening section 202. When the material enters the hopper 100 from the feed inlet 101, it is guided by the support component 201 and falls onto the screening section 202. Large gangue is blocked by the support component 201 and the screening section 202 to prevent large gangue from impacting the mine car.

[0045] Furthermore, the supporting component 201 includes a guide plate 201a disposed below the feed inlet 101, an arc-shaped plate 201b disposed at the bottom of the guide plate 201a, and a base plate 201c disposed at the bottom of the arc-shaped plate 201b; wherein, the guide plate 201a is located below the feed inlet 101, the arc-shaped plate 201b has multiple sets of through grooves 201d, and the screening part 202 is located on the base plate 201c;

[0046] Inside the hopper 100, below the feed inlet 101, a guide plate 201a is fixedly installed. The guide plate 201a is inclined and has multiple sets of elongated slots. An arc-shaped plate 201b is fixedly installed at the bottom of the guide plate 201a. Multiple sets of through slots 201d are opened on the arc-shaped plate 201b. The through slots 201d and the elongated slots can prevent larger pieces of gangue from falling, avoiding damage to the mine car due to the impact of heavy gangue falling. Simultaneously, the width of the elongated slots and the through slots 201d... The plates are relatively large, allowing most of the gangue to fall into the mine car for transportation, preventing gangue from clogging the hopper 100 and affecting the normal transportation of gangue. The bottom of the arc plate 201b is fixedly provided with a base plate 201c, which is inclined with a higher end. The screening part 202 is located on the base plate 201c, and the base plate 201c can support the screening part 202. The gangue entering the hopper 100 is guided by the guide plate 201a to fall onto the screening part 202.

[0047] Furthermore, the screening section 202 includes a rotating shaft 202a disposed in the hopper 100, an inclined plate 202b disposed outside the rotating shaft 202a, and a screen hole 202c opened on the inclined plate 202b; wherein, the end of the inclined plate 202b is located at the top of the bottom plate 201c.

[0048] A rotating shaft 202a is rotatably connected to the side of the hopper 100 away from the feed inlet 101. An inclined plate 202b is fixed on the outer side of the rotating shaft 202a. Multiple sets of screen holes 202c are opened on the inclined plate 202b. The end of the inclined plate 202b is placed on the bottom plate 201c, so that the inclined plate 202b is inclined with the end closer to the rotating shaft 202a being higher and the end closer to the support plate being lower. The inclination of the inclined plate 202b guides the gangue to fall after passing through the arc plate 201b. The through groove 201d and the screen holes 202c guide and screen the gangue. At the same time, the inclined plate 202b can make the gangue fall faster.

[0049] By setting up guide plates 201a, inclined plates 202b, and arc plates 201b, the gangue can be guided so that it falls into the mine car after being buffered by the hopper 100, thereby reducing the impact of the falling gangue on the mine car. As for the screening of gangue, larger gangue is blocked, preventing excessively heavy gangue from falling directly into the mine car and causing damage to the mine car, thus reducing the wear and tear on the mine car.

[0050] Example 2

[0051] In the above embodiment, when a large amount of gangue falls onto the inclined plate 202b at the same time, it is very easy for the gangue to block the inclined plate 202b, preventing the gangue from falling smoothly into the mine car.

[0052] Reference Figures 1-5 This embodiment differs from the first embodiment in that it also includes a vibration component 300, which includes a fixing component 301 disposed at the bottom of the inclined plate 202b and a rotating component 302 disposed below the inclined plate 202b; wherein, the rotating component 302 is disposed on the inner wall of the hopper 100, and the fixing component 301 cooperates with the rotating component 302 to enable the inclined plate 202b to reciprocate.

[0053] The fixed component 301 and the rotating component 302 cooperate. When the rotating component 302 operates, it abuts against the fixed component 301, causing the inclined plate 202b to repeatedly rise and fall. The rotation of the inclined plate 202b vibrates the gangue on it. When the inclined plate 202b falls and hits the bottom plate 201c, it also vibrates the curved plate 201b. This vibration helps the gangue fall more effectively, preventing it from clogging the inclined plate 202b. Simultaneously, the curved plate 201b... The angle is set with the axis of the rotating shaft 202a as the center, so that during the rotation of the inclined plate 202b, the end of the inclined plate 202b is always at the same distance from the arc plate 201b, preventing unscreened gangue from falling into the gap between the arc plate 201b and the inclined plate 202b. The bottom of the through groove 201d extends to the surface of the bottom plate 201c, and the bottom plate 201c itself is inclined, so that gangue is not easy to stay on the surface of the bottom plate 201c, and the inclined plate 202b can be reset normally.

[0054] Furthermore, the fixing component 301 includes a connecting plate 301a disposed at the bottom of the inclined plate 202b, and a fixing post 301b disposed on one side of the connecting plate 301a; wherein, the fixing post 301b corresponds to the rotating component 302; the connecting plate 301a is fixedly disposed at the bottom of the inclined plate 202b, and the fixing post 301b is fixedly disposed on one side of the connecting plate 301a. When the inclined plate 202b is placed on top of the base plate 201c, the fixing post 301b abuts against the rotating component 302. When the rotating component 302 moves, it can abut against the fixing post 301b, causing the inclined plate 202b to rotate up and down repeatedly.

[0055] Furthermore, the rotating assembly 302 includes a long shaft 302a disposed in the hopper 100, a rotating wheel 302b fixedly disposed outside the long shaft 302a, and multiple sets of helical teeth 302c disposed outside the rotating wheel 302b; wherein, the fixed column 301b can abut against the helical teeth 302c, a motor 302d is installed on the outside of the hopper 100, and the output end of the motor 302d is connected to the end of the long shaft 302a, and the long shaft 302a is located below the inclined plate 202b;

[0056] Long shafts 302a are rotatably connected to the inner walls on both sides of the hopper 100. The long shafts 302a are located below the fixed column 301b and are connected to the long shafts 302a through the output end of the motor 302d, enabling the motor 302d to drive the long shafts 302a to rotate. Multiple sets of rotating wheels 302b are fixedly provided on the outer side of the long shafts 302a, and multiple sets of helical teeth 302c are provided on the rotating outer side. When the end of the inclined plate 202b contacts the top of the bottom plate 201c, the bottom of the fixed column 301b is clamped between two sets of helical teeth 302c. In the angle, when the long axis 302a rotates in the first direction, i.e., the direction indicated by the arrow in the figure, the helical teeth 302c abut against the fixed column 301b, causing the fixed column 301b to rise. When the top of the helical teeth 302c moves away from the fixed column 301b, the drop between the top and bottom of the helical teeth 302c causes the fixed column 301b to fall. The fixed column 301b falls again between the two sets of helical teeth 302c, causing the inclined plate 202b to rotate upward and then fall. The gangue on its top vibrates with the arc plate 201b, and the gangue falls faster due to the vibration.

[0057] The rest of the structure is the same as in Example 1.

[0058] Operation process: In the initial state, the fixed column 301b is located in the angle between the two sets of helical teeth 302c, and the inclined plate 202b is located on top of the base plate 201c;

[0059] Gangue is transported from the feed inlet 101 into the hopper 100 by the conveying device. Guided by the guide plate 201a, the gangue falls onto the inclined plate 202b. The motor 302d is started, driving the long shaft 302a to rotate in the first direction. The long shaft 302a drives multiple sets of rotating wheels 302b to rotate. The helical gear 302c rotates and contacts the fixed column 301b, causing the inclined plate 202b to rotate upwards. When the fixed column 301b again aligns with the gap between the two sets of gears, it falls back down. The falling of 202b causes the arc plate 201b to vibrate, and the inclined plate 202b itself rotates and shakes repeatedly. The gangue on the top of the inclined plate 202b will also be vibrated. By vibrating the gangue, it can fall faster and avoid the inclined plate 202b and the arc plate 201b from blocking each other. At the same time, the outer side of the inclined tooth 302c is covered with a rubber layer to buffer the falling fixed column 301b and reduce the impact force of the falling fixed column 301b on the long axis 302a.

[0060] By incorporating the vibrating component 300, the feeding speed of the gangue is increased, preventing the gangue from clogging the device and ensuring the normal operation of the equipment. At the same time, it enables faster screening of the gangue, thereby improving the processing efficiency of the gangue screening.

[0061] Example 3

[0062] In the above embodiment, after a large amount of heavy gangue is screened out, the gangue remains between the inclined plate 202b and the arc plate 201b, making it difficult for the gangue on it to fall off, which in turn causes the equipment to be blocked.

[0063] Reference Figures 1-8 This embodiment differs from the above embodiments in that it also includes a crushing component 400, which includes a follower component 401 disposed on the rotating component 302, a crushing component 402 disposed on the arc plate 201b, and a connecting component 403 disposed between the inclined plate 202b and the crushing component 402; wherein, the inclined plate 202b can drive the crushing component 402 to move through the connecting component 403, and the crushing component 402 cooperates with the inclined plate 202b;

[0064] The rotary wheel 302b can drive the follower component 401 to move. The follower component 401 can lift the inclined plate 202b to a higher position. When the inclined plate 202b is raised to a higher position, it drives the crushing component 402 to move through the connecting component 403. The crushing component 402 cooperates with the inclined plate 202b to crush the gangue on its top, thereby preventing more gangue from staying on the inclined plate 202b and allowing the gangue to fall smoothly.

[0065] Furthermore, the follower assembly 401 includes a protrusion 401a disposed on the outer side of the rotating wheel 302b, and a fixing shell 401b disposed on one side of the rotating wheel 302b; wherein, the protrusion 401a and the fixing shell 401b cooperate to guide the fixing post 301b, and the fixing shell 401b is sleeved with the rotating wheel 302b.

[0066] A protrusion 401a is fixedly provided on the outer side of the cam. The length of the protrusion 401a is longer than that of the helical gear 302c. A fixed shell 401b is fixedly provided on one side of the rotating wheel 302b. The fixed shell 401b is sleeved on the outer side of the helical gear 302c and the protrusion 401a. The fixed post 301b is located in the fixed shell 401b. The fixed shell 401b is provided with an arc part S1. The end of the arc part S1 is connected to a guide part S2. The arc part S1 is sleeved with the helical gear 302c. The distance between the inner wall of the arc part S1 and the helical gear 302c is greater than the diameter of the fixed post 301b, so that the fixed post 301b has a certain amount of movement space to ensure the rotation of the inclined plate 202b.

[0067] The guide part S2 is sleeved on the outside of the protrusion 401a. The inner wall of the guide part S2 is parallel to the protrusion 401a, and the distance between them is slightly larger than the diameter of the fixing post 301b by a few millimeters. This reduces friction with the fixing post 301b while still guiding it. Since the fixing post 301b is always located in the fixing shell 401b, when the protrusion 401a rotates close to the fixing post 301b, the fixing post 301b is guided and limited by the fixing shell 401b, and is located within the protrusion 401a. Between the guide part S2 and the guide part S2, the fixed column 301b is lifted to a higher position, which in turn causes the inclined plate 202b to rotate upward. After the inclined plate 202b rises, it approaches the crushing component 402. At the same time, the inclined plate 202b drives the crushing component 402 to move through the connecting component 403. The two move in the same direction to crush the gangue. The setting of the guide sleeve and the protrusion 401a allows the inclined plate 202b to rotate to a higher position while reducing the impact on the long shaft 302a when the inclined plate 202b falls.

[0068] Furthermore, the compaction assembly 402 includes a fixed shaft 402a disposed in the through groove 201d, a rotating plate 402b disposed outside the fixed shaft 402a, and a pressure plate 402c disposed at the end of the rotating plate 402b; wherein, the connecting assembly 403 is connected to the rotating plate 402b.

[0069] A fixed shaft 402a is fixedly installed in the through groove 201d. A rotating plate 402b is rotatably connected to the outside of the fixed shaft 402a. A pressure plate 402c is fixedly installed at one end of the rotating plate 402b near the inclined plate 202b. The pressure plate 402c is located above the inclined plate 202b. The pressure plate 402c has a shape that is thicker near the end of the rotating plate 402b and narrower towards the end, so that its bottom surface and the surface of the inclined plate 202b are relatively parallel after rotation, which can better squeeze the gangue. The bottom of the pressure plate 402c is provided with multiple sets of protrusions to further improve the squeezing effect on the gangue. When the inclined plate 202b rotates upward, the connecting component 403 drives the rotating plate 402b to rotate, so that the pressure plate 402c rotates in the direction of the inclined plate 202b, and then the two work together to squeeze and crush the gangue.

[0070] Furthermore, the connecting assembly 403 includes a long plate 403a disposed at the end of the inclined plate 202b, and a cylinder 403b disposed on the long plate 403a; wherein, the rotating plate 402b has an oblong groove 402d, and the cylinder 403b is inserted into the oblong groove 402d.

[0071] The rotating plate 402b has a waist-shaped groove 402d, which is located at the end away from the pressure plate 402c. A cylinder 403b is inserted into the waist-shaped groove 402d. A long plate 403a is fixedly provided at the end of the inclined plate 202b. The ends of the two sets of long plates 403a are connected to the two sides of a set of cylinders 403b. When the inclined plate 202b rotates upward, the long plate 403a drives the cylinder 403b to move in the waist-shaped groove 402d, causing the rotating plate 402b to rotate around the fixed shaft 402a, which in turn drives the pressure plate 402c to rotate downward. The inclined plate 202b and the pressure plate 402c move closer to each other, so that the gangue can be crushed.

[0072] The rest of the structure is the same as in Example 2.

[0073] Operation process: In the initial state, the pressure plate 402c is inclined with the top higher, and the cylinder 403b is located at the end of the waist groove 402d near the arc plate 201b;

[0074] During the gangue conveying process, the rotor 302b rotates continuously, causing the inclined plate 202b to vibrate and screen the gangue. Because the inclined teeth 302c are arranged in multiple sets, the inclined plate 202b has a certain amount of time to screen the gangue. After a certain amount of gangue remains at its top, the gangue is shaken by the inclined plate 202b to a position near its bottom, i.e., below the pressure plate 402c. As the rotor 302b continues to rotate, the fixed column 301b enters between the protrusion 401a and the guide part S2. At this time, driven by the fixed column 301b, the inclined plate 202b gradually rotates upward to a higher position. During this process, the inclined plate... 202b drives the cylinder 403b to slide in the waist-shaped groove 402d via the long plate 403a, causing the cylinder 403b to push the rotating plate 402b to rotate. The pressure plate 402c is driven to rotate around the fixed shaft 402a, causing the pressure plate 402c and the inclined plate 202b to rotate towards each other, thereby crushing the gangue between them. When the inclined plate 202b vibrates, the pressure plate 402c can be driven to swing slightly, allowing the gangue on it to fall off. When the pressure plate 402c rotates downward, its top surface can rotate to a lower end, allowing the gangue on top to fall off.

[0075] By setting the crushing component 400, larger gangue can be crushed after being screened out, ensuring normal material feeding of the device and avoiding problems such as malfunction or shutdown caused by device blockage. At the same time, it can perform preliminary crushing treatment on gangue, thereby improving the processing efficiency of gangue.
