Another pulley 8 is fixed on the outer surface of the connecting shaft 3 outside the crushing box 1, and the pulleys 8 between the two rotating rods 7 and between the rotating rod 7 and the connecting shaft 3 are all connected by a transmission belt 9.

[0025] The following is a detailed description of the specific settings and functions of this embodiment: the conveyor mesh belt 6 away from the end of the crushing box 1 is arranged to be inclined upward toward the side away from the crushing box 1, and an auxiliary groove is provided at the bottom of the end of the cleaning box 5 away from the crushing box 1 for placing a collection box. A support frame 14 is fixed to the top surface of the cleaning box 5 on the side of the crushing box 1, and water pipes 15 are symmetrically arranged inside the support frame 14. The two water pipes 15 are connected through, and a number of nozzles 16 are equidistantly arranged on the bottom surfaces of the two water pipes 15. One end of the water pipe 15 passes through the outer end of the support frame 14 and is fixed with a water inlet 17. A drain pipe 18 is fixed at one end of the bottom of the cleaning box 5. The crushed stones falling on the conveyor mesh belt 6 can be washed through the water pipe 15 and the nozzle 16, which is convenient for subsequent use as raw materials.

[0026] A stirring rod 11 is provided above the conveyor mesh belt 6 near the end of the crushing box 1, and the stirring rod 11 is rotatably connected to the inner wall of the cleaning box 5 through a bearing. A number of paddles 12 are fixed at equal intervals on the outer surface of the stirring rod 11, and a gear 13 is fixed to one end of the stirring rod 11 extending to the outside of the cleaning box 5, and another gear 13 is meshed and connected to the side of the gear 13. A connecting rod 10 is fixed on the front side of the other gear 13, and the connecting rod 10 is rotatably connected to the rear wall of the cleaning box 5 through a bearing. Another pulley 8 is fixed on the connecting rod 10, and the pulley 8 and the pulley 8 on the rotating rod 7 near the connecting rod 10 are connected by a transmission belt 9. The gravel is moved by the paddle 12 to avoid incomplete cleaning and air drying of the gravel.

[0027] Example 2

[0028] like Figure 1-5 As shown, a bellows 19 is fixed on the top surface of the support frame 14, and a fan is provided in the middle of the bellows 19. A dust box 21 is slidably inserted into the bellows 19 above the fan, and a support plate 24 is symmetrically fixed inside the bellows 19 on the bottom surface of the dust box 21 for supporting the dust box 21. A filter screen 22 is fixed through the bottom surface of the dust box 21. The top surface of the bellows 19 is connected to the feeding box 4 through an air duct 20, and an air outlet window 25 cooperating with the air duct 20 is provided on the side of the feeding box 4.

[0029] The effect achieved by the entire embodiment is that an air outlet pipe 23 is fixed through the side wall of the bellows 19 on the side below the fan in the bellows 19, and the lower part of the air outlet pipe 23 is set to be bent toward the inclined conveyor belt 6, so that the exhausted wind can dry the cleaned gravel. A handle is fixed on the end of the dust box 21 facing the outside of the bellows 19, the air duct 20 is set to be bent to match the bellows 19, and an inlet groove matching the air duct 20 is opened on the top surface of the bellows 19. Protective nets are fixed inside the air outlet window 25 and inside the bellows 19 above and below the fan to prevent gravel from entering the air duct 20.

[0030] The method of use and working principle of this device: when it is necessary to recycle concrete waste blocks and stones, pour the concrete waste blocks and stones into the feeding box 4, turn on the driving motor 2, and the driving motor 2 drives the connecting shaft 3 to rotate, thereby driving the crushing roller to rotate, and at the same time drives the rotating rod 7 to rotate through the conveyor belt 9 and the pulley 8, thereby driving the two conveyor belts 6 to move, and the crushed gravel falls on the conveyor belt 6 and moves outward under the drive of the two conveyor belts 6. During the movement, clean water enters the water pipe 15 through the water inlet 17 and is sprayed out through the nozzle 16, so that the gravel can be cleaned. While washing, the pulley 8 and the conveyor belt 9 drive the connecting rod 10 to rotate. Under the action of the two stirring rods 11, the paddle 12 can be driven to rotate asynchronously with the conveyor roller in the conveyor mesh belt 6, so as to poke the gravel on the conveyor mesh belt 6, and push the gravel away for convenient washing and air drying. When crushing, the fan in the bellows 19 is turned on, and the dust in the feeding box 4 enters the dust collecting box 21 under the action of wind force. After the dust is filtered and collected by the filter screen 22, the air flow is discharged through the air outlet pipe 23, and the gravel to be discharged after cleaning can be air-dried. After the dust collecting box 21 collects a lot of dust, the dust collecting box 21 can be directly pulled out for cleaning.
