[0036] EMBODIMENT

[0037] Please refer to Figures 1-7 The present application provides a novel sandstone separator, which comprises a shell 1, a feed inlet 2, a large stone screening structure 3, a small sandstone screening structure 4, a mud screening structure 5, a water flow discharge structure 6 and a conveying structure 7.

[0038] Further, the shell 1 covers all structures except the feeding port 2 and the conveying structure 7, provides support for various structures, and avoids the situation that part of the stones fall outside during the sandstone separation process, causing safety accidents.

[0039] The feeding port 2 is fixedly installed at the top of the shell 1, and external workers pour the sandstone raw materials into the feeding port 2 by using various conveying devices.

[0040] The feeding port 2 is connected to the front end of the large stone screening structure 3, the large stone screening structure 3 is obliquely arranged in the shell 1, the tail end of the large stone screening structure 3 is connected to the conveying structure 7, the conveying structure 7 is connected to the external environment, and the large stones that are too large and too heavy are separated alone through the screening of the large stone screening structure 3, so as to avoid damaging the separation structure when they are mixed with sandstone and separated together.

[0041] The large stone screening structure 3 comprises a first ring plate 301, a roller 302, a second ring plate 303, a bolt 304, a gear ring 305, a gear wheel 306, and a first motor 307.

[0042] Specifically, the first ring plate 301 is rotationally connected to the outlet of the feeding port 2 pipeline, the first ring plate 301 is rotationally arranged in the shell 1 through a connecting plate, and the first ring plate 301 is maintained in rotation while providing support, a plurality of rollers 302 are inserted into the plate surface of the first ring plate 301, the rollers 302 are uniformly circumferentially arranged along the axis of the first ring plate 301, the other end of the roller 302 is slidably arranged through the second ring plate 303, the second ring plate 303 is rotationally arranged in the shell 1 through a connecting plate, and the second ring plate 303 is rotationally arranged in the shell 1 through the roller 302 and the first ring plate 301, and the second ring plate 303 provides support.

[0043] There is a gap between adjacent rollers 302, the gap is a screen hole smaller than the volume of the large stone, which is used to separate the large stone and the smaller sandstone particles, so that the sandstone particles fall into the lower part for separate separation. Among them, the two ring plates and the rollers 302 are obliquely arranged, the second ring plate 303 is located at the obliquely lower end and above the conveying structure 7, so as to facilitate the large stones to fall into the conveying structure 7 through the inclination angle.

[0044] The gear ring 305 is fixedly arranged outside the outer ring of the first ring plate 301, the gear ring 305 is engaged with the gear wheel 306, the gear wheel 306 is fixedly installed on the driving shaft of the first motor 307, the first motor 307 is fixedly installed in the shell 1, the first ring plate 301 is driven to rotate by the first motor 307, so as to drive the roller 302 to rotate, the feeding port 2 is connected to the cylindrical internal space formed by the circumferential arrangement of the rollers 302, so as to roll and screen the sandstone raw materials.

[0045] Preferably, the large stone blocks are worn out more easily in the separation process due to their large size and heavy weight, so the smooth roller 302 is provided to reduce the frictional resistance with the large stone blocks and reduce wear and tear, and the sand and gravel particles are quickly leaked into the lower part through the rotation of the roller 302.

[0046] In addition, the bolt 304 is threadedly sleeved on one end of the roller 302 passing through the second ring plate 303, and the roller 302 is provided with threads at this end, which are matched and connected with the threads of the bolt 304.

[0047] When part of the roller 302 is damaged, the bolt 304 can be loosened, the damaged roller 302 can be pulled out from the second ring plate 303, a new roller 302 can be inserted, and then the bolt 304 can be tightened to fix the roller 302 between the two ring plates.

[0048] Preferably, since the rollers 302 are uniformly arranged in a circle, when separating stone blocks of different sizes, part of the rollers 302 can be pulled out at uniform intervals to adjust the gap between adjacent rollers 302, thereby adjusting the size of the large stone blocks.

[0049] Further, the large stone block screening structure 3 is inclined and provided below the small sand and gravel screening structure 4, the small sand and gravel screening structure 4 corresponds to the position of the large stone block screening structure 3, the end of the small sand and gravel screening structure 4 is connected to the conveying structure 7, and the small sand and gravel screening structure 4 is responsible for further screening the sand and gravel screened out by the large stone block screening structure 3 to separate the sand and gravel particles from the mud.

[0051] The coarse sieve plate 401 is arranged on the displacement structure one, the displacement structure is arranged in the machine shell 1, and the displacement direction of the displacement structure one is perpendicular to the conveying direction of the conveying structure 7.

[0052] Preferably, the coarse sieve plate 401 is inclined, and the inclined lower end of the coarse sieve plate 401 is located above the conveying structure 7. The sand and gravel raw materials falling on the coarse sieve plate 401 are laterally and reciprocally displaced by the displacement structure, so that the sand and gravel raw materials are evenly spread on the entire surface of the coarse sieve plate 401 and do not accumulate at a certain place on the surface, facilitating rapid screening. The sieve holes on the coarse sieve plate 401 will filter out the sand and gravel particles, only allowing the mud to fall below the coarse sieve plate 401, and then the filtered sand and gravel particles will fall into the conveying structure 7 along the inclined surface for conveying out.

[0053] Further, the mud screening structure 5 is placed below the small sand and gravel screening structure 4, and the two structures correspond in position. The mud screening structure 5 includes a fine sieve plate 501, a displacement structure two, and a scraper 504.

[0055] Preferably, the fine holes on the fine sieve screen filter out the silt in the mud, and only allow water to flow into the lower part, and the filtered fine silt is relatively fine and can be used for subsequent construction.

[0056] Further, the water flow discharge structure 6 is arranged below the fine sieve plate 501, and the water flow discharge structure 6 is communicated with the external environment, so as to discharge the water filtered out by the mud screening structure 5 into the external environment.

[0057] Please refer to Figure 2 In the embodiment, the displacement structure one includes a belt 402, a secondary shaft 403, a rotating rod 404, a connecting rod 405, a sliding block 406, and a fixed plate 407.

The secondary shaft 403 is rotationally arranged in the shell 1. When the first motor 307 works, the secondary shaft 403 is driven to rotate by the belt 402. The secondary shaft 403 is fixedly connected to one end of the rotating rod 404. The other end of the rotating rod 404 is rotationally connected to one end of the connecting rod 405. The other end of the connecting rod 405 is rotationally connected to the sliding block 406. The sliding block 406 is slidingly arranged in the sliding groove in the fixed plate 407. When the secondary shaft 403 rotates, the rotating rod 404 performs circular motion around the axis of the secondary shaft 403, thereby driving the connecting rod 405 to reciprocate and swing, and driving the sliding block 406 to reciprocate. The sliding direction of the sliding block 406 is perpendicular to the conveying direction of the conveying structure 7. The sliding block 406 is fixedly connected to the coarse sieve plate 401, thereby driving the coarse sieve plate 401 to reciprocate. The coarse sieve plate 401 is provided with a plurality of coarse sieve holes smaller than the diameter of the sand particles.

[0059] In the embodiment, a plurality of water spray heads 408 are further arranged on the fixed plate 407. The water spray heads 408 are communicated with the external water pump through pipelines, and the water spray heads 408 are directed towards the surface of the coarse sieve plate 401. Since the sieve holes of the coarse sieve plate 401 are already small, the situation of partial mud accumulation and blockage may occur. In order to ensure normal separation, the water spray heads 408 can be used to spray water on the surface of the coarse sieve plate 401 to flush away the accumulated mud.

[0060] Please refer to Figure 2 and Figure 6 The displacement structure two includes a second motor 502 and a screw rod 503.

[0061] The second motor 502 is horizontally fixedly arranged in the shell 1, a driving shaft of the second motor 502 is fixedly connected with a screw rod 503, the screw rod 503 is threadedly matched with a connecting block, the connecting block is fixedly arranged with a scraper 504, the bottom of the scraper 504 is slidably abutted with the plate surface of the fine sieve plate 501, the fine sieve plate 501 is arranged with a plurality of fine sieve holes smaller than the diameter of the silt particles, and the fine sieve plate 501 near the conveying structure 7 is arranged with an inclined table, so that the scraper 504 can scrape the silt and collect it.
