Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, and in particular to a screening device for plastic particles used in rubber running tracks. Background Technology
[0002] Rubber track plastic granules are the core raw material for laying plastic running tracks. They are mainly made from waste tires, recycled rubber products, or virgin rubber through crushing and granulation processes. They have good elasticity, wear resistance, and weather resistance, and are key components of the elastic buffer layer and wear-resistant surface layer of the track.
[0003] The uniformity of particle size directly affects the quality of track laying. Inconsistent particle size can lead to uneven distribution during the paving process, resulting in deviations in the flatness of the track surface. This affects the foot feel and cushioning protection for athletes, and may even cause cracking of the structural layer due to excessively dense or sparse local particles. Therefore, it is necessary to screen the plastic particles. However, most existing screening equipment adopts an open structure. Since the plastic track particles themselves are recycled from waste tire rubber, dust is easily generated during screening, which has a certain impact on workers and the environment. Utility Model Content
[0004] The purpose of this invention is to solve the technical problems mentioned above, and to propose a rubber track particle screening device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a particle screening device, comprising a box body, a hopper fixedly installed on the top surface of the box body, a control panel fixedly installed on one side surface of the box body, a sieve plate fixedly installed on one side inner wall surface of the box body, a vibrating motor fixedly installed on one side surface of the sieve plate, a slag discharge plate fixedly installed in a through groove on one side surface of the box body, an inclined plate fixedly installed on one side inner wall surface of the box body, two guide plates fixedly installed on one side surface of the inclined plate, a feed pipe fixedly installed on one side surface of the box body, and a dustproof device provided inside the box body. The dustproof device includes two rotating shafts, both of which are rotatably connected between the two side inner walls of the box body. Baffles are fixedly installed on the surfaces of both rotating shafts. Two long plates are fixedly installed between the two side inner wall surfaces of the box body. The rotating shafts enable the baffles to rotate.
[0006] Preferably, two first springs are fixedly installed on the top surfaces of the two long plates, and the ends of each pair of first springs away from the long plates are fixedly connected to the baffle. Two vertical rods are fixedly installed on the top surface of the box, and circular plates are fixedly installed at the top ends of the two vertical rods. Two long extension plates are fixedly installed on the arc-shaped surface of the hopper, and the two long extension plates are fixedly connected to the vertical rods. The first springs have the effect of driving the baffle to rotate.
[0007] Preferably, a cover plate is slidably connected to the surface of both vertical rods, and a second spring is fixedly installed on the bottom surface of both circular plates. The ends of the two second springs away from the circular plates are fixedly connected to the cover plates, and a handle is fixedly installed on the top surface of the cover plates. The second springs are designed to drive the cover plates to slide on the surface of the vertical rods.
[0008] Preferably, a dredging device is provided on one side of the box body. The dredging device includes a rotating motor, which is fixedly installed on one side surface of the box body. A turntable is fixedly installed at the output end of the rotating motor, and a round rod is fixedly installed on one side surface of the turntable. The rotating motor is configured to drive the turntable to rotate.
[0009] Preferably, a short plate is rotatably connected to the surface of the round rod, a limiting groove is formed on one side surface of the short plate, and a limiting rod is fixedly installed on one side surface of the box body. The limiting rod passes through the limiting groove, and the cooperation between the limiting groove and the limiting rod has the effect of restricting the movement direction of the short plate.
[0010] Preferably, a rectangular plate is fixedly installed on one side surface of the box body, and a through hole is opened on one side surface of the rectangular plate. A rubber hammer is fixedly installed on one side surface of the short plate, and the rubber hammer passes through the through hole. The through hole restricts the movement direction of the rubber hammer.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] In this invention, by incorporating a dustproof device, when screening plastic granules is required, the vibrating motor is first activated, causing the screen plate to vibrate. Then, the handle is moved upwards, causing the cover plate to slide upwards on the vertical rod surface. This upward sliding of the cover plate compresses the second spring, allowing the plastic granules to be poured into the hopper. The granules then fall onto two baffles. When the granules accumulate to a certain level, the baffles rotate and compress the first spring, causing the granules to fall onto the screen plate. Once the granules have been poured in, the baffles are released. Open the handle, and the rebound force of the second spring will cause the cover plate to slide down the vertical rod until the cover plate is tightly attached to the surface of the hopper. As the plastic granules fall, the weight on the baffle plate becomes less and less. With the rebound force of the first spring, the baffle plate will gradually rotate and return to its original position. When the baffle plate is fully returned to its original position, the dust prevention work is completed. Through the cooperation of the above structure, the screening device can be sealed during the sorting of plastic granules, preventing dust and debris from flowing back from the hopper to the outside of the box during feeding, avoiding air pollution, reducing the harm of dust to workers, and improving the safety of the device during use.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Please see Figure 1-4This utility model provides a technical solution: a plastic particle screening device for rubber running tracks, including a box body 1, a hopper 4 fixedly installed on the top surface of the box body 1, a control panel 5 fixedly installed on one side surface of the box body 1, a screen plate 6 fixedly installed on one side inner wall surface of the box body 1, a vibration motor 7 fixedly installed on one side surface of the screen plate 6, a through groove 8 opened on one side surface of the box body 1 and a slag discharge plate 9 fixedly installed thereon, an inclined plate 10 fixedly installed on one side inner wall surface of the box body 1, two guide plates 11 fixedly installed on one side surface of the inclined plate 10, and a feed pipe 12 fixedly installed on one side surface of the box body 1.
[0023] The specific setup and function of its dustproof device 2 and unblocking device 3 will be explained below.
[0024] In this embodiment: the interior of the box 1 is equipped with a dustproof device 2, which includes two rotating shafts 201. Both rotating shafts 201 are rotatably connected between the inner walls on both sides of the box 1. Baffles 202 are fixedly installed on the surface of both rotating shafts 201. Two long plates 203 are fixedly installed between the inner walls on both sides of the box 1.
[0025] In this embodiment, the rotating shaft 201 enables the baffle 202 to rotate.
[0026] Specifically, two first springs 204 are fixedly installed on the top surface of each of the two long plates 203. The end of each pair of first springs 204 away from the long plate 203 is fixedly connected to the baffle 202. Two vertical rods 205 are fixedly installed on the top surface of the box 1. A circular plate 206 is fixedly installed at the top end of each of the two vertical rods 205. Two long extension plates 207 are fixedly installed on the arc-shaped surface of the hopper 4. Both long extension plates 207 are fixedly connected to the vertical rods 205.
[0027] In this embodiment, the first spring 204 serves to drive the baffle 202 to rotate.
[0028] Specifically, cover plates 208 are slidably connected to the surfaces of the two vertical rods 205, and second springs 209 are fixedly installed on the bottom surfaces of the two circular plates 206. The ends of the two second springs 209 away from the circular plates 206 are fixedly connected to the cover plates 208. A handle 210 is fixedly installed on the top surface of the cover plates 208. The second springs 209 are designed to drive the cover plates 208 to slide on the surfaces of the vertical rods 205.
[0029] In this embodiment: a clearing device 3 is provided on one side of the housing 1. The clearing device 3 includes a rotary motor 31, which is fixedly installed on one side surface of the housing 1. A turntable 32 is fixedly installed at the output end of the rotary motor 31, and a round rod 33 is fixedly installed on one side surface of the turntable 32. When it is necessary to clear the discharge pipe 12, the rotary motor is started first. The start of the rotary motor will drive the turntable 32 to rotate. The rotation of the turntable 32 will drive the round rod 33 to perform circular motion. The circular motion of the round rod 33 will drive the short plate 34 to move back and forth. With the cooperation of the limiting rod 36 and the limiting groove 35, one end of the short plate 34 moves up and down back and forth. The reciprocating movement causes the rubber hammer 39 to move up and down repeatedly. The rubber hammer 39 is limited by the through hole 38. The reciprocating movement of the rubber hammer 39 continuously impacts the outer wall surface of the feed pipe 12. The continuous impact on the outer wall surface of the feed pipe 12 causes the feed pipe 12 to vibrate. The vibration of the feed pipe 12 causes the plastic particles that are blocked inside to scatter and clear the blockage. With the cooperation of the above structure, it is not necessary to clear the blockage of the feed pipe 12 in time, avoiding the situation where the feed pipe 12 cannot discharge material. At the same time, it avoids the accumulation of plastic particles caused by the blockage of the feed pipe 12, thereby avoiding the inclined plate 10 from bearing an overload of weight, or even the accumulation and blockage of one side of the screen plate 6.
[0030] Specifically, a short plate 34 is rotatably connected to the surface of the round rod 33. A limiting groove 35 is opened on one side surface of the short plate 34. A limiting rod 36 is fixedly installed on one side surface of the housing 1, and the limiting rod 36 passes through the limiting groove 35.
[0031] In this embodiment, the combination of the limiting groove 35 and the limiting rod 36 effectively restricts the movement direction of the short plate 34.
[0032] Specifically, a rectangular plate 37 is fixedly installed on one side surface of the box 1, and a through hole 38 is opened on one side surface of the rectangular plate 37. A rubber hammer 39 is fixedly installed on one side surface of the short plate 34, and the rubber hammer 39 passes through the through hole 38.
[0033] In this embodiment, the through hole 38 serves to restrict the movement direction of the rubber hammer 39.
[0034] Working principle: By setting up the dustproof device 2, when it is necessary to screen plastic granules, the vibration motor 7 is first started, which drives the screen plate 6 to vibrate. Then, the handle 210 is moved upward. The upward movement of the handle 210 causes the cover plate 208 to slide upward on the surface of the vertical rod 205. The upward sliding of the cover plate 208 on the surface of the vertical rod 205 compresses the second spring 209. At this time, plastic granules can be poured into the hopper 4. After entering the hopper 4, the plastic granules fall onto the two baffles 202. When the plastic granules accumulate to a certain extent, the baffles 202 will rotate and compress the first spring 209. 04. At this point, the plastic granules will fall onto the screen plate 6. When the plastic granules have been poured in, release the handle 210. With the help of the rebound force of the second spring 209, the cover plate 208 will slide downward on the vertical rod 205 until the cover plate 208 is tightly attached to the surface of the hopper 4. As the plastic granules fall, the weight on the baffle 202 decreases. With the help of the rebound force of the first spring 204, the baffle 202 will gradually rotate and reset. When the baffle 202 is completely reset, the dust prevention work is completed. Through the cooperation of the above structure, the screening device can be sealed during the sorting of plastic granules to prevent them from falling into the dust. During material handling, dust and debris are poured back from hopper 4 to the outside of housing 1, preventing air pollution, reducing the harm of dust to workers, and improving the safety of the device during use. When it is necessary to unclog the discharge pipe 12, the rotary motor is started first. The start of the rotary motor will drive the turntable 32 to rotate, which will drive the circular rod 33 to perform a circular motion. The circular motion of the circular rod 33 will drive the short plate 34 to move back and forth. With the cooperation of the limiting rod 36 and the limiting groove 35, one end of the short plate 34 will move up and down. The up and down movement of one end of the short plate 34 will drive the rubber hammer 39 to move up and down. By using the through hole 38 to limit the rubber hammer 39, the rubber hammer 39 moves up and down repeatedly and will continuously hit the outer wall surface of the feed pipe 12. The continuous impact on the outer wall surface of the feed pipe 12 will cause the feed pipe 12 to vibrate. The vibration of the feed pipe 12 will cause the plastic particles that are blocked inside to scatter and clear the blockage. With the cooperation of the above structure, it is not necessary to clear the blockage of the feed pipe 12 in time, avoiding the situation where the feed pipe 12 cannot discharge material. At the same time, it avoids the accumulation of plastic particles caused by the blockage of the feed pipe 12, thereby avoiding the inclined plate 10 from bearing an overload of weight, or even the accumulation and blockage of one side of the screen plate 6.
