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.

[0021] The utility model provides two technical solutions:

[0022] Figure 1-4 The first embodiment is shown: a concrete waste recycling device comprises a box body 1, a feed hopper 2 is fixedly provided at the upper left of the box body 1, a crushing structure 3 for crushing concrete is provided inside the box body 1, a dust reduction assembly 4 is fixedly provided on one side of the feed hopper 2, the crushing structure 3 comprises two crushing rollers 31 rotatably arranged inside the box body 1, a pulley 32 is fixedly provided at one end of the crushing roller 31, a multi-groove pulley 33 is rotatably provided on the outer wall of the box body 1 between the two crushing rollers 31, the multi-groove pulley 33 is fixedly connected to a motor 34, the pulley 32 is connected to the multi-groove pulley 33 through a belt drive, the multi-groove pulley 33 is connected to a grinding assembly 5 through a belt drive, the grinding assembly 5 comprises a transmission shaft 51, and a fixed motor 34 is provided at the end of the transmission shaft 51. A bevel gear A52 is fixedly provided, and a bevel gear B53 is meshed with the bevel gear A52. A rotating shaft 54 ​​is fixedly provided on the bevel gear B53, and a grinding block 55 is fixedly provided on the rotating shaft 54. A grinding plate 56 matching the grinding block 55 is fixedly provided inside the box body 1, and a plurality of groups of cleaning scrapers are evenly and fixedly connected to the side of the grinding block 55. The cleaning scrapers are used to clean the grinding block 55 to prevent the concrete from sticking to the grinding plate 56 and causing a decrease in grinding quality, thereby ensuring its grinding quality. The dust reduction component 4 includes a water tank 41 arranged on one side of the box body 1, and a water pump 42 is fixedly connected to the water tank 41 through a water pipe 43, and the output end of the water pump 42 is fixedly connected to a sprinkler plate 44 arranged on the top wall inside the box body 1 through a water outlet pipe.

[0023] The device crushes the concrete by means of the crushing roller 31 and at the same time, the water flow in the water tank 41 is sprayed on the concrete inside the box body 1 through the water pump 42 through the sprinkler plate 44, so as to achieve dust reduction treatment for the dust generated when the concrete is crushed, thereby reducing dust emissions and protecting the environment. At the same time, the crushing shaft can also be cooled, and then the crushed concrete is processed again by the grinding block 55 and the grinding plate 56, so that the crushed concrete maintains a relatively uniform size, which is convenient for the subsequent recycling of the concrete.

[0024] Figure 2-3 A second embodiment is shown, which mainly differs from the first embodiment in that a guide groove is fixedly provided below the crushing shaft, and a feeding auger is fixedly provided on the rotating shaft 54 ​​inside the guide groove, through which the crushed concrete is conveyed, thereby preventing the concrete from being blocked in the guide groove and ensuring its feeding efficiency, a partition plate with a higher left side and a lower right side is fixedly provided below the grinding plate 56, and a discharge port is fixedly provided at the lowest point of the partition plate, and two mutually engaged dustproof plates 6 are rotatably provided inside the feed hopper 2, and the dustproof plates 6 are fixedly connected to the inner wall of the feed hopper 2 by a reset spring 7.

[0025] The multi-groove pulley 33 fixedly connected to the motor 34 is used to rotate the crushing roller 31 and the grinding block 55, thereby crushing and grinding the concrete, thereby improving the utilization rate of its resources and reducing its recycling cost.

[0026] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0027] When in use, concrete is transported to the box body 1 through the feed hopper 2, and the dust plate is pushed open by the weight of the concrete itself. When the concrete enters the box body 1, the dust plate 6 returns to the initial position under the action of the return spring 7, thereby realizing the sealing of the feed hopper 2, and then the motor 34 and the water pump 42 are started, so that the motor 34 drives the crushing roller 31 to initially crush the concrete through the multi-groove pulley 33. At the same time, the water pump 42 sprays the water flow in the water tank 41 through the sprinkler plate 44 onto the concrete inside the box body 1 through the water pipe 43. The crushed concrete is transported to between the grinding block 55 and the grinding plate 56 through the guide groove, and the transmission shaft 51 is driven to rotate by the belt on the multi-groove pulley 33, and the rotating shaft 54 ​​on the bevel gear B53 is driven to rotate by the bevel gear A52 at the end of the transmission shaft 51, so as to realize the grinding of the crushed concrete, thereby ensuring that the crushed concrete maintains a relatively uniform size, and the ground concrete is discharged through the discharge pipe.
