DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figures 1 to 4 , the utility model provides a technical solution:

[0024] A filtering structure for removing blocks from concrete comprises a crushing assembly for crushing lumps, the crushing assembly comprising two groups of symmetrically arranged crushing rollers 1, the crushing rollers 1 being rotatably mounted in a crushing box 2, the crushing teeth on the surfaces of the two groups of crushing rollers 1 being meshed with each other, the bottom of the crushing box 2 being fixedly connected to the top of an inclined channel 3, a feed hopper 7 being fixedly mounted on the top of the crushing box 2, two groups of first motors 8 being fixedly mounted on one side of the crushing box 2, the output ends of the first motors 8 being transmission-connected with the two groups of crushing rollers 1 respectively, the crushing box 2 being fixedly mounted on one side of a support frame 15, and by arranging two groups of mutually meshing crushing rollers 1 below the feed hopper 7, lumps in the concrete can be crushed, cement and sand can be remixed in the concrete, and the lumps can be prevented from affecting the use of the concrete, while ensuring the strength of the concrete.

[0025] It also includes a filtering component for filtering concrete. The filtering component includes a filtering box 4 and a synchronous belt 5. One side of the filtering box 4 is fixedly connected to the bottom of the ramp channel 3. The synchronous belt 5 is arranged inside the filtering box 4. A plurality of first filter plates 6 are fixedly installed on the surface of the synchronous belt 5. The first filter plates 6 are installed obliquely. An outlet is opened at the bottom of the filtering box 4. A driven roller 9 is rotatably installed at the bottom of the filtering box 4. The driven roller 9 is drivingly connected to a driving roller 10 through the synchronous belt 5. The driving roller 10 is rotatably installed at the top of the filtering box 4. The driving roller 10 is drivingly matched with the output end of the second motor 11. The second motor 11 is fixedly installed on one side of the filtering box 4. A second filter plate 12 is fixedly installed at the outlet of the bottom of the filtering box 4. A slag outlet 13 is opened on the other side of the filtering box 4. A slag discharge plate 14 is fixedly installed below the slag outlet 13. The filtering box 4 is fixedly installed on the other side of the support frame 15. By setting the second motor 11, the driving roller 10, the driven roller 9 and the synchronous belt 5, the first filter plates 6 can be driven to perform periodic movement, so as to continuously filter. And by installing the first filter plates 6 obliquely, when moving upward, the outer side of the first filter plate 6 is high and the inner side is low, avoiding the stones from sliding outward on the surface of the first filter plate 6. After passing through the highest point of the synchronous belt 5, the first filter plate 6 flips and moves downward, so that the outer side of the first filter plate 6 is low and the inner side is high, facilitating the stones to slide from the surface of the first filter plate 6 to the slag discharge plate 14, thus completing slag discharge, preventing the stones from accumulating inside the filtering box 4, and ensuring the filtering effect.

[0026] During specific use, move this device to the designated position, turn on the two first motors 8, control the output ends of the two first motors 8 to drive the two crushing rollers 1 to rotate towards each other, add concrete to the feed hopper 7. The concrete slides downward under gravity and enters the crushing box 2. The two rotating crushing rollers 1 crush the lumps and larger stones in the concrete. The sand, cement and stones after crushing are remixed in the concrete and slide downward together, enter the filtering box 4 through the ramp channel 3. At the same time, turn on the second motor 11. The output end of the second motor 11 drives the driving roller 10 to rotate, so that the synchronous belt 5 and the driven roller 9 rotate. The first filter plates 6 on the surface of the synchronous belt 5 start to rotate clockwise. The concrete entering the filtering box 4 moves downward. After passing through the first filter plates 6, the larger stones are filtered out on the top surface of the first filter plates 6. The concrete continues to move downward. After being filtered by multiple groups of first filter plates 6 moving from bottom to top, it finally gathers at the outlet at the bottom of the filtering box 4. After being filtered again by the second filter plate 12, it is discharged from the filtering box 4. At the same time, the stones on the surface of the first filter plates 6 are driven upward until after passing through the highest point of the filtering box 4, the top surface of the first filter plate 6 flips to the bottom, throwing the stones towards another group of first filter plates 6 below, and sliding towards the slag outlet 13 on the surface of the inclined first filter plates 6, and being discharged from the slag discharge plate 14.
