[0002] At present, with the rapid development of my country's economy, the construction industry is developing rapidly. In construction sites, sand is an indispensable technical raw material, but there are many small stones in the sand. In order to improve the quality of construction, the sand needs to be screened. The traditional operation is a combination of manual and screening methods, but it is time-consuming and labor-intensive, and the screening efficiency is low. Now, vibrating sand screening devices are mostly used to screen sand and stone.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Example 1
[0035] See also Figure 1-Figure 6As shown, the purpose of this embodiment is to provide an anti-clogging vibrating screen for sand and stone separation, including a vibrating part 100, the vibrating part 100 includes a frame 102, a side wall of the frame 102 is provided with a vibrating motor 103, the vibrating motor 103 is used to drive the frame 102 to vibrate, a screen body 101 is provided inside the frame 102, the screen body 101 separates the sand and stone on the surface when vibrating, and removes impurities in the sand, a toggle assembly 300 is provided above the screen body 101, the toggle assembly 300 is used to toggle the sand and stone on the surface of the screen body 101, so that the sand and stone accumulated on the surface of the screen body 101 are spread on the surface of the screen body 101, and the contact area between the sand and stone and the surface of the screen body 101 is increased, and at the same time, the toggle assembly 300 toggle the sand and stone, so that the rolling friction between the sand and stone is reduced, and the sand and stone are accumulated at the sieve holes on the surface of the screen body 101;
[0036] A transport assembly 400 is provided below the sieve body 101, and the transport assembly 400 is used to transport and collect the sand sieved by the sieve body 101. A vibration assembly 500 is provided above the transport assembly 400. When the transport assembly 400 transports and collects the sand, the transport assembly 400 is moved to knock and vibrate the sieve body 101, so that the sand attached to the sieve holes on the surface of the sieve body 101 is separated.
[0037] A supporting portion 200 is disposed below the vibration portion 100 , and the supporting portion 200 is used to adjust the angle of the vibration portion 100 .
[0038] The vibrating part 100 vibrates the sand and gravel to make it pass through the sieve body 101 for screening. The shifting assembly 300 shifts the sand and gravel on the surface of the sieve body 101 to make the accumulated sand and gravel spread on the surface of the sieve body 101, thereby increasing the contact area between the sand and gravel and the surface of the sieve body 101. The sand in the sand and gravel is separated through the sieve holes on the surface of the sieve body 101, thereby improving the separation efficiency of the sand and gravel. In the process of shifting the sand and gravel by the shifting assembly 300, the shifting assembly 300 shifts the stones stuck at the sieve holes on the surface of the sieve body 101. The stones are subjected to horizontal shifting force and thus move away from the inner wall of the sieve holes, thereby avoiding the sieve holes being blocked by the stones, thereby improving the separation efficiency of the sand and gravel. The screened sand is transported and collected by the transport assembly 400. When the component 400 is transporting sand, the transport component 400 collides with the vibration component 500, causing the vibration component 500 to rotate and hit the bottom of the sieve body 101, thereby enhancing the vibration effect of the sieve body 101, and causing the stones stuck at the sieve holes to loosen on the inner wall of the sieve holes due to the increased vibration force. When the shifting component 300 rotates to shift the stones stuck on the inner wall of the sieve holes, while the stones are loosened on the inner wall of the sieve holes due to the increased vibration force, the stones are subjected to horizontal shifting force, thereby moving away from the inner wall of the sieve holes, thereby increasing the service life of the sieve body 101. At the same time, the vibration component 500 resets after colliding with the transport component 400, and at the same time, the bottom of the sieve body 101 is hit twice, thereby improving the hitting efficiency of the sieve body 101 and improving the sand and stone separation speed.
[0039] When vibrating and separating sand and gravel, considering that sand and gravel are easy to accumulate, resulting in low separation efficiency, the toggle assembly 300 includes a servo motor 301 arranged on the side wall of the frame 102, and the output shaft of the servo motor 301 is provided with a transmission gear 302, and the end of the transmission gear 302 is meshed with a swing rod 303. By controlling the rotation direction of the servo motor 301, the transmission gear 302 drives the swing rod 303 to horizontally reciprocate the sand and gravel on the surface of the screen body 101, and the transmission gear 302 is driven to rotate by the output shaft of the servo motor 301. The swing rod 303 at the end of the transmission gear 302 is meshed and rotated, and the swing rod 303 toggles the sand and gravel accumulated on the surface of the screen body 101, so that the accumulated sand and gravel are spread on the surface of the screen body 101, increasing the contact area between the sand and gravel and the surface of the screen body 101, and under the action of the vibration motor 103, the sand in the sand and gravel is separated through the sieve holes on the surface of the screen body 101, thereby improving the separation efficiency of sand and gravel.
[0040] When the sand and gravel are separated, some stones are stuck in the sieve holes on the surface of the sieve body 101. When multiple sieve holes are blocked, the sand and gravel separation efficiency is low. Therefore, a rubber ball 304 is provided under the swing rod 303. The rubber ball 304 is used to sweep the stones stuck in the sieve holes on the surface of the sieve body 101 to keep the stones away from the inner wall of the sieve holes. When the swing rod 303 rotates, the swing rod 303 drives the rubber ball 304 to move the sand and gravel on the surface of the sieve body 101. When the rubber ball 304 moves the stones stuck in the sieve holes on the surface of the sieve body 101, the stones are subjected to horizontal pushing force, thereby staying away from the inner wall of the sieve holes, avoiding the sieve holes being blocked by the stones, thereby improving the sand and gravel separation efficiency.
[0041] When separating sand and gravel, in order to facilitate the rapid collection of the separated sand and detect the quality of the sand at the same time, the transportation component 400 includes a conveyor belt 401 arranged under the sieve body 101, and the conveyor belt 401 is used to transport and collect the separated sand. A plurality of partition plates 402 are arranged on the surface of the conveyor belt 401. When the sand falls on the surface of the conveyor belt 401 from the sieve holes on the surface of the sieve body 101, the sand is transported and collected by the conveyor belt 401, so as to avoid secondary transportation by the operators and save the operators' physical strength. At the same time, by arranging the partition plates 402 on the surface of the conveyor belt 401, the sand falling on the surface of the conveyor belt 401 is automatically separated into different areas, and the quality of the sand and gravel in different areas is observed to judge the quality of the sand and gravel, thereby improving the accuracy of the judgment on the quality of the sand and gravel.
[0042] When there is a lot of sand on the surface of the conveyor belt 401, the sand in the lower layer of the conveyor belt 401 is affected by gravity and may adhere to the end surface of the partition plate 402. When the partition plate 402 moves to the sand collection point, it is difficult for the sand to fall to the designated location, causing pollution to the environment. Therefore, the ends of the partition plates 402 are provided with through grooves 403. When the sand on the surface of the conveyor belt 401 is transmitted to the collection point, the sand falls freely through the through grooves 403. By providing the through grooves 403 at the ends of the partition plates 402, since the contact area between the partition plates 402 and the sand is small, when the sand is transmitted to the collection point through the conveyor belt 401, the sand falls freely under the action of gravity, so that the sand falls to the designated collection point to avoid polluting the environment.
[0043] Considering that in the process of separating sand and stone, the stone is subjected to vibration, and the sharp corners of the stone are stuck in the sieve holes, resulting in low screening efficiency of the sieve body 101. In order to avoid the sieve holes being blocked, the vibration component 500 includes a support rod 501 arranged above the conveyor belt 401, and a plurality of support plates are arranged on the surface of the support rod 501. The support plates are rotatably connected with striking members 502, and the striking members 502 rotate on the surface of the support rod 501. When the sand and stone are screened, the conveyor belt 401 drives the partition plate 402 to move. During the movement of the partition plate 402, the end of the partition plate 402 and the striking member 502 are in contact with each other. 02 end collides, causing the striking piece 502 to rotate on the surface of the support rod 501. At the same time, the end of the striking piece 502 away from the collision with the end of the partition plate 402 strikes the bottom of the screen body 101 during the rotation process, thereby enhancing the vibration effect of the screen body 101, so that the stones stuck at the screen hole are loosened on the inner wall of the screen hole due to the increased vibration force. When the rubber ball 304 rotates to push the stones stuck on the inner wall of the screen hole, while the stones are loosened on the inner wall of the screen hole due to the increased vibration force, the stones are subjected to horizontal pushing force, thereby staying away from the inner wall of the screen hole, avoiding the screen hole being blocked by stones, thereby improving the sand and stone separation efficiency.
[0044] In order to improve the striking efficiency of the striking member 502 on the screen body 101 and increase the sand and stone separation speed, elastic members 503 are provided on both sides of the striking member 502. The striking member 502 is at an angle of 45° to the horizontal under the action of the elastic member 503. When the striking member 502 rotates on the surface of the support rod 501 under the action of external force, the striking member 502 is quickly reset by the elastic member 503. When the conveyor belt 401 drives the partition plate 402 to collide with the end of the striking member 502, the striking member 50 2 rotates on the surface of the support rod 501, and the end of the striking member 502 away from the end of the partition plate 402 strikes the bottom of the screen body 101 during the rotation process. The screen body 101 is struck by external force to enhance the vibration effect. When the top of the partition plate 402 passes through the bottom of the striking member 502, the striking member 502 is reset by the force of the elastic member 503, and the bottom of the screen body 101 is struck for the second time, thereby improving the striking efficiency of the screen body 101 and improving the sand and stone separation speed.
[0045] When vibrating and screening sand and gravel, in order to facilitate timely understanding of the sand and gravel content and timely addition of sand and gravel after the sand and gravel separation is completed, a symmetrical observation window 104 is provided on the side wall of the frame 102. The observation window 104 is used to observe the sand and gravel content inside the frame 102. The sand and gravel separation status inside the frame 102 is observed in real time through the observation window 104, so as to facilitate technical understanding of the actual situation of sand and gravel separation and screening, and to facilitate timely addition of unscreened sand and gravel after the sand and gravel separation is completed.
[0046] When the screen body 101 is tilted, the contact area between the sand and the sieve holes can be increased, thereby improving the sand and stone screening efficiency. Therefore, the support part 200 includes a base 201 arranged under the frame 102, and the frame 102 and one end of the base 201 are provided with a symmetrical cylinder 202, and the end away from the cylinder 202 is rotatably connected with a support leg. By adjusting the height of the cylinder 202, the angle of the frame 102 is adjusted. When the screen body 101 needs to be tilted, the cylinder 202 is started, and the piston rod at the end of the cylinder 202 pushes the frame 102 to move upward, so that the frame 102 rotates along the support leg as a whole, thereby adjusting the angle of the screen body 101, increasing the contact area between the sieve holes on the surface of the screen body 101 and the sand and stones, thereby quickly screening the sand and stones.
[0047] In summary, the working principle of this solution is as follows: when in use, the vibration motor 103 is started to drive the frame 102 to vibrate, and the sieve body 101 provided on the inner wall of the frame 102 vibrates at the same frequency, and the unscreened sand and gravel are poured onto the surface of the sieve body 101. The sand and gravel on the surface of the sieve body 101 are affected by the vibration, and the sand bodies with small diameters are screened out from the sieve mesh on the surface of the sieve body 101, and the sand bodies fall on the surface of the conveyor belt 401 for transmission and collection. When more sand and gravel accumulate on the surface of the sieve body 101, in order to improve the screening efficiency, the output end of the servo motor 301 drives the transmission gear 302 to rotate, and the swing rod 303 meshed with the end of the transmission gear 302 rotates. Above the screen body 101, the accumulated sand and gravel are moved by the swing rod 303, so that the sand and gravel are spread flat on the surface of the screen body 101, increasing the contact area between the sand and the surface of the screen body 101, thereby improving the screening efficiency of the sand. Since the stones contained in the sand and gravel are mostly irregular in shape during the screening process, the screaming parts of the stones are easily stuck on the inner wall of the screen hole during the screening process, resulting in the blockage of the screen hole of the screen body 101, affecting the sand and gravel screening efficiency. Therefore, when the partition plate 402 provided on the surface of the conveyor belt 401 is in horizontal transmission motion, the end of the partition plate 402 collides with the end of the striking member 502 during the movement of the partition plate 402, so that The striking member 502 rotates on the surface of the support rod 501. At the same time, the end of the striking member 502 that is away from the end of the partition plate 402 strikes the bottom of the screen body 101 during the rotation process, thereby enhancing the vibration effect of the screen body 101, so that the stones stuck at the screen holes are loosened on the inner wall of the screen holes due to the increased vibration force. When the rubber ball 304 provided at the bottom of the swing rod 303 rotates to move the stones stuck on the inner wall of the screen holes, while the stones are loosened on the inner wall of the screen holes due to the increased vibration force, the stones are horizontally pushed by the rubber ball 304, so that the stones are away from the inner wall of the screen holes, thereby avoiding the clogging of the screen holes due to the stones, thereby improving the sand and stone separation efficiency. The rate is improved, and at the same time, the service life of the screen is improved. When the top of the partition plate 402 passes through the bottom of the striking piece 502, the striking piece 502 is reset by the force of the elastic piece 503, and at the same time, the bottom of the screen body 101 is struck for the second time, which improves the striking efficiency of the screen body 101 and the sand and stone separation speed. In order to improve the sand and stone separation efficiency, the stones are collected and cleaned at the same time. Therefore, the piston rod at the end of the support rod 501 pushes the frame 102, so that the frame 102 rotates along the supporting leg as a whole, thereby adjusting the angle of the screen body 101, increasing the contact area between the sieve holes on the surface of the screen body 101 and the sand and stones, thereby improving the sand and stone screening efficiency.
