[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] See also Figures 1 to 15 , the present invention provides a technical solution:

[0065] A stone washing and mud removing device for roadbed and pavement construction of a highway project comprises a mounting support plate 1. The mounting support plate 1 is generally L-shaped, but the front and rear positions of the top protrude outwards, such as Figure 1 As shown, the next step is to install the left and right sides of the lower end surface of the support plate 1 using the vertical plates in a suspended state.

[0066] A main motor 2 is fixedly installed at the rear end of the upper part of the mounting support plate 1, and the output shaft of the main motor 2 faces the right side. Two groove rings 201 are eccentrically fixedly installed on the circumferential surface of the output shaft, and a ring 202 is rotatably installed at the position of the groove on the circumferential surface of the groove ring 201 (because in the subsequent operation, due to the limitation of the screening box 204, the ring 202 will not rotate synchronously with the groove ring 201), and a first connecting rod 203 is fixedly installed on the outer circumferential surface of the ring 202, such as Figure 5 shown.

[0067] A screening box 204 is fixedly installed at the front end of the first connecting rod 203, and an inclined screening plate 205 is fixedly installed at the lower end of the interior of the screening box 204 in an inclined state. Then, a first discharge port 206 is opened at the center position of the lower end of the right side surface of the screening box 204, and a first dust removal port 207 is opened from the inner bottom surface to the lower end surface of the screening box 204. Then, a first dust removal pipe 208 is fixedly connected to the lower end of the screening box 204. (It should be noted that since the screening box 204 needs to move back and forth, in order to prevent the first dust removal pipe 208 from affecting the movement of the screening box 204, an extendable cloth bag is used at the position where it is fixedly connected to the screening box 204. Therefore, the screening box 204 will not be unable to move during operation), and then two second connecting rods 209 are fixedly installed at the front end of the screening box 204. Then, two fixed connecting rods 210 matching the second connecting rod 209 are fixedly installed at the front right side of the upper part of the mounting support plate 1, and the front and rear of the fixed connecting rod 210 are hollow structures, and a first spring 211 is fixedly installed inside the fixed connecting rod 210, and the rear end of the first spring 211 is fixedly connected to the corresponding second connecting rod 209, as shown in FIG. Figure 3 and Figure 4 shown.

[0068] In addition, a first motor 3 is fixedly installed at the upper right corner of the screening box 204, and a water spray pipe 301 is fixedly installed on the output shaft of the first motor 3. The water spray pipe 301 is located inside the screening box 204, such as Figure 4 As shown, a row of water spray holes are provided on the circumferential surface of the water spray pipe 301 from left to right, so that the water inside the water spray pipe 301 can be sprayed out under the action of pressure, and then two water injection pipes 302 are fixedly installed on the outer circumferential surface of the water spray pipe 301, and the upper ends of the water injection pipes 302 can be connected to external pipelines, and then clean water is continuously transported to the inside of the water spray pipe 301 under the action of an external water pump.

[0069] Finally, a first triangular tube 212 is fixedly installed on the right side of the screening box 204 outside the first discharge port 206 , and a hose 213 is fixedly installed on the right end of the first triangular tube 212 .

[0070] Therefore, during use, the main motor 2 is started, and the output shaft of the main motor 2 will rotate with the groove ring 201. At this time, the ring 202 will not rotate with the groove ring 201, because it is restricted by the first connecting rod 203 and the screening box 204, and the ring 202 can only move back and forth. Since the groove ring 201 and the output shaft of the main motor 2 are in an eccentric setting, the groove ring 201 will move the ring 202 back and forth, and the ring 202 will move back and forth synchronously with the first connecting rod 203, and the first connecting rod 203 will move back and forth with the screening box 204, and the screening box 204 will move synchronously with the inclined screening plate 205 when moving. Under the action of the inclined screening plate 205, the stones inside the screening box 204 can be filtered at a primary level.

[0071] The filtered waste soil will pass through the first dust collecting port 207 into the first dust collecting pipe 208 , and then pass through the first dust collecting pipe 208 to be collected by an external container.

[0072] Then, when the screening box 204 moves, it will move synchronously with the second connecting rod 209, and the second connecting rod 209 will pull up the first spring 211. At the same time, the second connecting rod 209 slides inside the fixed connecting rod 210, and its front end will not slide out of the fixed connecting rod 210, thereby avoiding the screening box 204 from collapsing.

[0073] Secondly, under the action of the water injection pipe 302, the water spray pipe 301 can continuously perform the first flushing operation on the stones inside the screening box 204. The first motor 3 is started, and the output shaft of the first motor 3 will drive the water spray pipe 301 to adjust the angle, so that clean water can flush the stones at farther and closer positions.

[0074] Finally, under the operation of the screening box 204, the stones filtered for the first time will pass through the first discharge port 206 into the interior of the first triangular tube 212, and then enter the interior of the hose 213. It should be noted that when the screening box 204 moves, it will move synchronously with the first triangular tube 212, and because the hose 213 is dynamic, it will not affect the first triangular tube 212, and thus will not affect the movement of the screening box 204.

[0075] The stones entering the hose 213 will enter the screening box 401 in the screening assembly 4, such as Figure 1 As shown, three second discharge ports 402 are provided on the right side of the screening box 401 from top to bottom, a second dust removal port 403 is provided on the inner bottom surface of the screening box 401, and a second dust removal pipe 404 is fixedly installed on the lower surface of the screening box 401 at the outer side of the second discharge port 402, as shown in FIG. Figure 7 and Figure 1 shown.

[0076] Then, the first screening plate 405, the second screening plate 406 and the third screening plate 407 are rotatably installed inside the screening box 401 by using hinges (wherein the hinge connection position is located on the right side of the lower end of the first screening plate 405, the second screening plate 406 and the third screening plate 407), and the upper end surfaces of the first screening plate 405, the second screening plate 406 and the third screening plate 407 are respectively in a flush state with the lower side of the second discharge port 402 corresponding to the right side, as shown in FIG. Figure 7 shown.

[0077] Then, a limiting plate 408 in a front-to-rear symmetrical state is fixedly installed on the right side of the upper end surface of the first screening plate 405, the second screening plate 406 and the third screening plate 407, and the right side openings of the two limiting plates 408 are consistent in size with the opening of the second discharge port 402. Therefore, during use, the stone can pass through the second discharge port 402 smoothly under the action of the limiting plate 408.

[0078] In addition, there is a certain distance between the left sides of the first screening plate 405, the second screening plate 406 and the third screening plate 407 and the inner wall of the screening box 401, so as to avoid the first screening plate 405, the second screening plate 406 and the third screening plate 407 from contacting the inner wall of the screening box 401 during subsequent rotation, causing the first screening plate 405, the second screening plate 406 and the third screening plate 407 to be unable to rotate.

[0079] In addition, a vibrator 410 is fixedly installed on the left side of the lower end surface of the first screening plate 405, the second screening plate 406 and the third screening plate 407. Under the action of the vibrator 410, the first screening plate 405, the second screening plate 406 and the third screening plate 407 can be vibrated to speed up the stone screening operation. Figure 7 shown.

[0080] In addition, symmetrical third connecting rods 411 are fixedly installed at the positions near the edges of the left front and rear of the upper end surfaces of the first screening plate 405, the second screening plate 406 and the third screening plate 407, and the tops of the third connecting rods 411 are fixedly installed with second springs 412, and the tops of the second springs 412 are fixedly installed with cavity tubes 413, and the upper ends of the third connecting rods 411 are slidably installed inside the cavity tubes 413, such as Figure 7 shown.

[0081] The top cavity tube 413 is fixedly installed on the inner upper end of the screening box 401, the middle cavity tube 413 is fixedly installed on the lower end surface of the first screening plate 405, and the lower cavity tube 413 is fixedly installed on the lower end surface of the second screening plate 406.

[0082] In addition, the filtering holes of the first screening plate 405 are larger than those of the second screening plate 406, and the filtering holes of the second screening plate 406 are larger than those of the third screening plate 407. This is because during use, stones smaller than the first screening plate 405 will fall to the upper end surface of the second screening plate 406, while stones larger than the first screening plate 405 will be blocked. Stones smaller than the second screening plate 406 will fall to the upper end surface of the third screening plate 407, while stones larger than the second screening plate 406 will be blocked. Moreover, the vibrator 410 can prevent stones from getting stuck in the filtering holes.

[0083] An inclined plate 409 is fixedly installed on the inner bottom surface of the screening box 401. Under the action of the inclined plate 409, stones smaller than the third screening plate 407 can smoothly pass through the second dust outlet 403 and then enter the second dust outlet pipe 404, thereby preventing stones from accumulating inside the screening box 401.

[0084] Then, a telescopic cylinder 414 is fixedly installed on the outer left side surface of the screening box 401, and a U-shaped rod 415 is fixedly installed on the telescopic rod of the telescopic cylinder 414. The other end of the U-shaped rod 415 passes through the screening box 401 and the upper end surface of the first screening plate 405 for rotational connection.

[0085] Therefore, during use, after the stone enters the screening box 401, under the action of the vibrator 410, the first screening plate 405, the second screening plate 406 and the third screening plate 407 are in a vibrating state, and the fallen stones are screened by the first screening plate 405, the second screening plate 406 and the third screening plate 407 and pass through the second discharge port 402 one by one under the action of the limiting plate 408.

[0086] Secondly, during the vibration of the first screening plate 405 , the second screening plate 406 and the third screening plate 407 , the third connecting rod 411 will move synchronously, and the third connecting rod 411 will stretch the second spring 412 .

[0087] In addition, in order to cope with the speed of the stone rolling down, the telescopic cylinder 414 is started, and the telescopic rod of the telescopic cylinder 414 moves upward with the U-shaped rod 415, and the U-shaped rod 415 will move the first screening plate 405, and the first screening plate 405 will move the second screening plate 406, and the second screening plate 406 will move the third screening plate 407 upward synchronously. Under the action of the hinge, the first screening plate 405, the second screening plate 406 and the third screening plate 407 can only rotate, so the inclination angle of the first screening plate 405, the second screening plate 406 and the third screening plate 407 becomes larger, thereby increasing the speed of the stone. On the contrary, the telescopic rod of the telescopic cylinder 414 moves downward with the U-shaped rod 415, and the inclination angle of the first screening plate 405, the second screening plate 406 and the third screening plate 407 becomes smaller, and the speed of the stone sliding out of the screening box 401 will slow down.

[0088] Under the action of the first screening plate 405, the second screening plate 406 and the third screening plate 407, smaller stones can pass through the second dust removal port 403, and then pass through the second dust removal pipe 404 into the container prepared outside.

[0089] Finally, a second triangular tube 416 is fixedly installed on the right side of the screening box 401 at the outer edge of the second discharge port 402, and a connecting tube 417 is fixedly installed on the right end of the second triangular tube 416. Fig. 9 As shown, the stones passing through the second discharge port 402 will enter the interior of the second triangular tube 416, then enter the interior of the connecting tube 417, and finally enter the interior of the chemical cylinder 501 in the cleaning assembly 5, as shown in FIG. Fig. 9 shown.

[0090] The interior of the chemical cylinder 501 is a hollow structure, and the upper and lower ends are through-structured. Then, an injection hole 502 is opened on the outer circumferential surface of the chemical cylinder 501 to the inside, and the injection hole 502 is through-connected with the external pipeline. The required chemical solution can be continuously injected into the interior of the chemical cylinder 501 through the pipeline and the injection hole 502. Fig.10 shown.

[0091] Then, a material distribution plate 503 is fixedly installed at the upper end of the inside of the chemical cylinder 501. The material distribution plate 503 is a truncated cone structure, and three material distribution openings 504 are annularly opened from the upper end to the lower end surface of the material distribution plate 503. A second motor 505 is fixedly installed at the center position of the lower end surface of the material distribution plate 503. The second motor 505 is a double-axis motor, and the output shaft of the lower end of the second motor 505 extends to the outside of the chemical cylinder 501, as shown in FIG. Fig.10 shown.

[0092] The output shaft at the upper end of the second motor 505 passes through the material distribution plate 503, and three disturbing rods 506 are fixedly installed on the circumferential surface of the upper output shaft, and the first gear 507 is fixedly installed on the output shaft at the lower end of the second motor 505. Fig.11 shown.

[0093] Then, a fixing plate 508 is fixedly installed at the opening of the lower end of the chemical cylinder 501. Three through holes of a circular structure are arranged in an annular array from the upper end surface to the lower end surface of the fixing plate 508. In addition, the output shaft of the second motor 505 passes through the fixing plate 508. Cleaning tubes 509 are rotatably installed inside the three through holes on the fixing plate 508. The inner walls of the through holes are in a concave state, and the corresponding positions of the cleaning tubes 509 protrude outward, thereby ensuring that the cleaning tubes 509 can be in a vertical state, such as Fig.12 shown.

[0094] Moreover, the upper end of the cleaning tube 509 extends to the lower end of the material distribution port 504, and the lower end of the cleaning tube 509 extends to the outside of the chemical cylinder 501, and then, a second gear 510 is fixedly installed on the outer circumferential surface of the lower end of the cleaning tube 509, and the second gear 510 and the first gear 507 are in a meshing state.

[0095] In addition, a micro pump 511 is fixedly installed on the upper outer portion of the cleaning tube 509, and a soft brush 514 is fixedly installed on the inner circumferential surface of the cleaning tube 509. Fig.13 As shown, the soft brushes 514 are arranged longitudinally in a ring shape and are evenly distributed inside the cleaning tube 509, and six delivery tubes 513 are fixedly installed inside the cleaning tube 509 between adjacent soft brushes 514, and the delivery tubes 513 are fixedly connected to the upper end of the external micro pump 511.

[0096] Therefore, during use, a portion of the stones that enter the chemical cylinder 501 pass through the distribution port 504 and enter the bottom of the distribution plate 503, and a portion of them stay on the upper part of the distribution plate 503. At this time, the second motor 505 is started, and the output shaft of the second motor 505 will rotate with the disruptor rod 506. Under the action of the disruptor rod 506, the stones can be swept into the distribution port 504 one by one, and then pass through the distribution port 504.

[0097] After passing through the material distribution port 504, the stone will enter the interior of the cleaning tube 509, and under the weight of the stone itself, it will pass through the soft brushes 514 arranged in layers, and the soft brushes 514 can brush the surface of the stone passing through, so that the mud adhered to the surface of the stone after washing can be cleaned off, and during the operation of the soft brush 514, the micro pump 511 is started (the micro pump 511 is in a waterproof state and will not fail to operate when it encounters water), and the micro pump 511 can transport the chemical solution in the chemical cylinder 501 to the interior of the second annular nozzle 512 (The second annular nozzle 512 is fixedly installed on the outer circumferential surface of the multiple delivery pipes 513, and is used to connect the multiple delivery pipes 513). Under the action of the second annular nozzle 512, the chemical solution can be transported to the inside of the delivery pipe 513, and fine holes are opened on the circumferential surface of the delivery pipe 513. Under the action of the fine holes, the chemical solution can be sprayed out, and then the chemical solution can operate on the passing stone. In the case where there is some rust on the surface of the stone, the rust on the surface of the stone can be cleaned under the action of the chemical solution, thereby ensuring the long-term subsequent use of the stone.

[0098] Moreover, when the output shaft of the second motor 505 rotates, it will rotate synchronously with the first gear 507, and the first gear 507 will drive the second gear 510 to rotate synchronously. Under the action of the second gear 510, the cleaning tube 509 can rotate synchronously, so that the soft brush 514 and the conveying tube 513 can perform 360-degree operation on the surface of the stone.

[0099] Finally, a feed pipe 101 matching the cleaning pipe 509 is fixedly installed on the upper right side of the mounting support plate 1, and the stones passing through the cleaning pipe 509 will enter the interior of the feed pipe 101 because the upper end of the feed pipe 101 and the lower end of the cleaning pipe 509 are in a fitted state.

[0100] Then, three evenly distributed first annular nozzles 102 are fixedly installed at the inner upper end of the feed pipe 101, and the first annular nozzles 102 are connected to an external water pipe, so as to flush the passing stones and wash away the chemical components on the surface of the stones.

[0101] Working principle: First, the main motor 2, the output shaft of the main motor 2 will rotate with the groove ring 201, the groove ring 201 will rotate with the ring 202, the ring 202 will rotate with the first connecting rod 203, the first connecting rod 203 will rotate with the screening box 204,

[0102] The screening box 204 filters the internal stones for the first time, and the first motor 3 is started. The output shaft of the first motor 3 drives the water spray pipe 301 to rotate, and the water spray pipe 301 washes the stones inside the screening box 204.

[0103] The finished stones pass through the first triangular tube 212 , through the hose 213 and into the interior of the screening box 401 .

[0104] Under the action of the vibrator 410, the first screening plate 405, the second screening plate 406 and the third screening plate 407 are in vibration, and the stones will pass through the second discharge port 402 one by one under the action of the limiting plate 408 after being screened by the first screening plate 405, the second screening plate 406 and the third screening plate 407.

[0105] Start the telescopic cylinder 414, the telescopic rod of the telescopic cylinder 414 moves the U-shaped rod 415, and the U-shaped rod 415 moves the first screening plate 405, so that the second screening plate 406 and the third screening plate 407 can move synchronously, thereby changing the inclination angles of the first screening plate 405, the second screening plate 406 and the third screening plate 407.

[0106] Finally, the stones enter the interior of the corresponding chemical cylinder 501 through screening.

[0107] The second motor 505 is started, and the output shaft of the second motor 505 rotates with the disturbing rod 506 and the first gear 507 . The disturbing rod 506 sweeps the stones one by one into the material distribution port 504 , allowing the stones to enter the interior of the cleaning tube 509 .

[0108] The first gear 507 drives the second gear 510 to rotate, and the second gear 510 rotates synchronously with the cleaning tube 509. The cleaning tube 509 performs an all-round cleaning operation on the stone under the action of the soft brush 514 and the conveying tube 513.
