[0026] According to the present specific embodiment, the lower hopper 102 is fixedly connected to the top of the casing 101 and communicates with the interior of the casing 101, the water tank 103 is fixedly connected to one side of the casing 101, the two water supply pipes 104 are fixedly connected to the top of the water tank 103 and communicate with the interior of the water tank 103, and are located on both sides of the casing 101, each of the water pumps 105 is arranged on each of the water supply pipes 104, the two water mist nozzles 106 are fixedly connected to the two sides of the lower hopper 102 and are arranged opposite to each other, and each of the water mist nozzles 106 is fixedly connected and communicated with each of the water supply pipes 104, the screening and transporting assembly is located in the casing 101, the re-crushing assembly is located on one side of the casing 101 and communicates with the interior of the casing 101, and the collecting box 107 is located between the casing 101 and the re-crushing assembly Below, when processing concrete waste, start the two water pumps 105, pump the water in the water tank 103 into the two water mist nozzles 106 from the two water supply pipes 104 respectively, and the water flow is sprayed out from the two water mist nozzles 106. When the concrete residue passes through the lower hopper 102 and enters the casing 101, it will be wetted by the water sprayed by the two water mist nozzles 106. At this time, the wetted concrete residue will not generate a large amount of dust during crushing, and the small amount of dust generated will also be wetted by the water sprayed by the two water mist nozzles 106 and fall down. The crushed concrete will fall on the screening and transportation component. If it is of suitable size, it will be discharged from the casing 101 and enter the collecting box 107. Otherwise, it will be transported to the re-crushing component by the screening and transportation component, and fall into the collecting box 107 after being crushed again, which can reduce dust while making the crushing effect of the device more powerful.

[0027] Among them, the secondary crushing box 108 is fixedly connected to one side of the casing 101, and the two secondary crushing rollers 109 are rotatably connected to the secondary crushing box 108 and are symmetrically arranged in the secondary crushing box 108. When the larger concrete residue enters the crushing box 108 for secondary crushing after crushing, the crushing box 108 provides a working place for secondary crushing. When the concrete residue touches the two rolling secondary crushing rollers 109, it is crushed into smaller concrete by the two secondary crushing rollers 109 and falls into the collecting box 107.

When transporting larger volumes of concrete, the transport motor 115 provides power for the entire screening and transport assembly, and the double-gear drive shaft 116 rotates with the transport motor 115 to transmit power.

[0030] At the same time, the auxiliary gear shaft 117 is rotatably connected to the housing 101 and is arranged opposite to the double gear drive shaft 116. The chain plate conveyor belt 118 is sleeved outside the double gear drive shaft 116 and the auxiliary gear shaft 117, and meshes with the double gear drive shaft 116 and the auxiliary gear shaft 117, and is provided with a large number of leakage holes. The chain plate conveyor belt 118 is composed of a plurality of hinged stainless steel plates and two endless chains. When the crushed concrete residue falls on the chain plate conveyor belt 118, the concrete of the appropriate volume will leak from the leakage holes and then be collected in the collection box 107 waiting for use; the larger concrete will be intercepted in the Above the chain-plate conveyor belt 118, the transport motor 115 is started, and the double-gear drive shaft 116 starts to rotate, driving the chain-plate conveyor belt 118 meshing therewith to rotate. At the same time, the auxiliary gear shaft 117 is also rotated under the drive of the chain-plate conveyor belt 118 to ensure that the chain-plate conveyor belt 118 will not get stuck or bulge. The large volume of concrete above the chain-plate conveyor belt 118 moves toward the crushing box 108 as the chain-plate conveyor belt 118 rotates, and rolls into the crushing box 108 when contacting the crushing box 108, and is crushed again, so that the size of the collected concrete particles is more uniform.

[0031] At the same time, the two protective pipes 119 are fixedly connected to the casing 101 and respectively wrap the two water supply pipes 104. The two protective covers 120 are fixedly connected to the top of the lower hopper 102 and are respectively connected to the two protective pipes 119.

When the concrete residue passes through the lower hopper 102 and enters the housing 101, it will be wetted by the water sprayed by the two water mist nozzles 106. At this time, the wetted concrete residue will not generate a large amount of dust when it is crushed, and the small amount of dust generated will also be wetted by the water sprayed by the two water mist nozzles 106 and fall down; When the crushed concrete residue falls on the chain plate conveyor belt 118, concrete of appropriate volume will leak from the leak hole and then be collected in the collection box 107 for use; larger concrete will be intercepted above the chain plate conveyor belt 118, the transport motor 115 is started, the double gear drive shaft 116 starts to rotate, driving the chain plate conveyor belt 118 meshing with it to rotate, and at the same time, the auxiliary gear shaft 117 is also rotated under the drive of the chain plate conveyor belt 118 to ensure that the chain plate The conveyor belt 118 will not get stuck or bulge. The large volume of concrete above the chain plate conveyor belt 118 moves toward the crushing box 108 as the chain plate conveyor belt 118 rotates, and rolls into the crushing box 108 when contacting the crushing box 108 for re-crushing, so that the size of the collected concrete particles is more uniform. When the concrete residue is crushed again, the crushing motor 111 is started, and the driving gear 112 starts to rotate, driving the transmission gear 113 to rotate in the opposite direction, thereby driving the two re-crushing rollers 109 to roll in the opposite direction, crushing the contacted concrete residue into smaller concrete, and then the concrete falls from the re-crushing box 108 into the collection box 107. The device can reduce dust and make the crushing effect of the device more powerful, avoiding the problem that the prior art cannot reduce dust when processing concrete, and a large amount of flying dust will be generated when the device is working, blocking the workers' sight and causing certain damage to the environment, thereby achieving the effect of reducing dust and protecting the environment.
