DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Embodiment

[0023] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a regenerated sand and gravel cleaning and pulverizing machine for concrete processing, including a bottom plate 1. A water tank 2 is fixedly connected to the top of the bottom plate 1. The water tank 2 is located on the left half of the bottom plate 1. A pulverizing box 3 is fixedly connected to the top of the water tank 2. A first feed port 4 is opened at the top of the pulverizing box 3. A pulverizing chamber is provided inside the pulverizing box 3. The pulverizing chamber is cylindrical. The inner wall of the pulverizing chamber is rotatably connected with pulverizing rollers 5. There are two pulverizing rollers 5. Grooves 7 are opened on the left and right inner walls of the pulverizing box 3. The left groove 7 is lower than the right groove 7. Both grooves 7 are located below the pulverizing chamber. The inner wall of the groove 7 is slidably connected with a first filter plate 8. The first filter plate 8 is in an inclined shape with the left side lower and the right side higher. Four springs 9 are fixedly connected to the top of the first filter plate 8. The springs 9 are respectively located at the four corners of the top of the first filter plate 8. A motor 6 is fixedly installed on the left side wall of the pulverizing box 3. There are two motors 6 and they are respectively in transmission connection with the two pulverizing rollers 5. A first discharge port 13 is opened on the left side wall of the pulverizing box 3. The first discharge port 13 is located above the left side of the first filter plate 8 and to the left of the left groove 7. The top of the spring 9 is fixedly connected to the inner top wall of the groove 7. A telescopic plate 10 is provided on the right side of the left spring 9. The telescopic plate 10 is located between the first filter plate 8 and the groove 7. A placement plate 11 is fixedly connected to the inner wall of the pulverizing box 3. The placement plate 11 is located below the first filter plate 8. A vibrator 12 is fixedly installed on the top of the placement plate 11. The top of the vibrator 12 is in close contact with the bottom of the first filter plate 8. The inner bottom wall of the pulverizing box 3 is in an inclined shape with the left side higher and the right side lower.

[0024] During use, when crushing, since some sand and gravel fall directly without being crushed through the gap between the crushing roller 5 and the inner wall of the crushing box 3, the size of the sand and gravel discharged from the crushing box 3 will be uneven, which is not conducive to concrete processing and production. Therefore, there is a regenerated sand and gravel cleaning crusher for concrete processing. When the sand and gravel need to be processed for concrete, it needs to be crushed first. At this time, the sand and gravel are put into the first feed inlet 4, and at the same time, the motor 6 is started, so that the crushing roller 5 starts to rotate to crush the sand and gravel. Subsequently, the crushed sand and gravel fall on the top of the first filter plate 8 for filtering. At this time, the vibrator 12 is started. Through the cooperation setting of the spring 9 and the vibrator 12, the first filter plate 8 can be vibrated up and down to prevent the sand and gravel from piling up and causing abnormal filtering of the sand and gravel. Through the inclined setting of the first filter plate 8 with the left end lower than the right end, the unqualified sand and gravel can slide from right to left on the top of the first filter plate 8 to the first discharge port 13 and be discharged, and then put into the first feed inlet 4 again for repeated crushing until it is qualified. Through the setting of the telescopic plate 10, it can prevent the sand and gravel from jamming the spring 9 when rolling, resulting in the spring 9 being unable to return to its normal position. When the qualified sand and gravel pass through the first filter plate 8 and fall on the inner bottom wall of the crushing box 3, through the inclined setting of the inner bottom wall of the crushing box 3 with the left end higher than the right end, the qualified sand and gravel can roll from left to right to the second feed inlet 14 and enter the inside of the cleaning box 15.

A second electric telescopic rod 22 is fixedly connected to the inner bottom wall of the cleaning box 15. There are two second electric telescopic rods 22 and they are symmetrically distributed left and right with respect to the cleaning box 15. The telescopic end of the second electric telescopic rod 22 is fixedly connected to a baffle 19. A first electric telescopic rod 18 is fixedly connected to the top of the baffle 19. The first electric telescopic rods 18 correspond to the second electric telescopic rods 22 one by one. The telescopic ends of the two first electric telescopic rods 18 are fixedly connected to the left and right bottom sides of the second filter plate 17. A second discharge port 23 is provided on the right side wall of the cleaning box 15. The size of the second discharge port 23 is smaller than that of the baffle 19. A drainage plate 20 is fixedly connected between the two baffles 19.

[0026] In use, when washing sand and gravel, due to the accumulation of sand and gravel, the surface cleaning of some sand and gravel is not clean enough, and some impurities will be mixed in during the concrete processing, affecting the quality of the concrete. Therefore, there is a regenerated sand and gravel cleaning and crushing machine for concrete processing. When the sand and gravel enter the inside of the cleaning tank 15 from the second feed port 14, the sand and gravel fall above the second filter plate 17. At this time, the telescopic ends of the left and right first electric telescopic rods 18 are successively extended and contracted, so that the left half and the right half of the second filter plate 17 can be successively raised, so that the sand and gravel on the top of the second filter plate 17 roll back and forth. At this time, start the water pump 25 to send the water in the water tank 2 into the inside of the water pipe 26, and then enter the water plate 27 from the water pipe 26 and spray out from the high-pressure nozzle 28 to wash the sand and gravel on the top of the second filter plate 17. The water flow carries the debris and dust and flows from the filter holes on the top of the second filter plate 17 to the top of the drainage plate 20. Through the inclined setting of the top of the drainage plate 20 with the front lower and the rear higher, the water flow can carry the debris and dust to flow to the front half of the drainage plate 20, and then be discharged from the inside of the cleaning tank 15 through the drain pipe 21.
