[0013] The present utility model provides a concrete waste crushing and separating device. By setting a screen mesh and controlling the start of the vibration motor, the conveying frame body can be driven to vibrate on the bottom surface of the crushing box. The crushed concrete blocks fall downward. Since the screen mesh and the conveying frame body are fixedly installed, the screen mesh can be driven to vibrate synchronously. Also, because the length of the baffle is greater than the length of the conveying frame body and is inclined, the larger crushed blocks after vibrating screening will be discharged to one side through the screen mesh, while the smaller crushed blocks will be discharged outward through the conveying frame body, thus achieving the purpose of effectively screening crushed concrete blocks of different sizes.

[0014] The present utility model provides a concrete waste crushing and separating device. By setting a humidifying component and controlling the start of the water pump, during the start of the water pump, the external water source can be conveyed to the inside of the water distribution frame through the connecting pipe. Finally, through the continuous conveyance of water by the water pump, the internal pressure of the water distribution frame gradually increases, and finally sprays into the inside of the feeding box through the water outlet pipes and the atomizing nozzles. The misty water source can humidify the concrete blocks and reduce the dust generated during crushing. Description of the Drawings

[0023] The following gives specific embodiments.

[0024] Please refer to Figures 1-4 , the present utility model provides a concrete waste crushing and separating device, including a main frame body 1, a crushing box 2 is fixedly installed inside the main frame body 1, a feed box 3 is fixedly installed on the top surface of the crushing box 2, a humidifying component 4 is arranged on the top surface of the feed box 3, a rotating shaft 21 is rotatably installed inside the crushing box 2, a crushing roller 22 is fixedly installed on the outer surface of the rotating shaft 21, a driving motor 5 is fixedly installed on the top surface of the main frame body 1, and pulleys 6 are fixedly installed at the output end of the driving motor 5 and one end of the rotating shaft 21 respectively, and a transmission belt 7 is sleeved between the two pulleys 6.

[0025] During operation, first, the concrete blocks to be crushed are added into the inside of the feed box 3, and they fall into the inside of the crushing box 2 under their own gravity. Then, by starting the driving motor 5, the crushing roller 22 is driven to rotate at a high speed inside the crushing box 2, and the concrete blocks entering the inside of the crushing box 2 are squeezed and crushed during the rotation.

[0026] Extension frames 9 are fixedly installed on the two side surfaces of the main frame 1, a conveying frame 8 is arranged below the extension frame 9, a mounting frame 10 is fixedly installed on the bottom surface of the conveying frame 8, a vibration motor 11 is installed on one side surface of the mounting frame 10, a fixing frame 12 is fixedly installed above the conveying frame 8, a screen 13 is fixedly installed inside the fixing frame 12, a connecting frame 15 is fixedly installed on the bottom surface of the extension frame 9, a connecting shaft 16 is fixedly installed inside the connecting frame 15, a hanging frame 17 is arranged below the connecting frame 15, a hook 20 is movably connected to the inside of the hanging frame 17, one end of the hook 20 is located inside the hanging frame 17, and a clamping plate 19 is arranged on the outer surface, the hook 20 is hung on the outer surface of the connecting shaft 16, and the bottom end of the hanging frame 17 is hung on the outer surface of the conveying frame 8, baffles 14 are fixedly installed on both ends of the top surface of the fixing frame 12, and a spring 18 is fixedly connected between the clamping plate 19 and the bottom surface of the hanging frame 17.

[0027] During operation, the vibration motor 11 is started by control. During the process of starting the vibration motor 11, the conveying frame 8 can be driven to vibrate on the bottom surface of the crushing box 2, and the crushed concrete blocks fall downward and first fall on the top surface of the screen 13. Since the screen 13 is fixedly installed with the conveying frame 8, the screen 13 can be driven to vibrate synchronously during the vibration of the conveying frame 8. Since the length of the baffle 14 is greater than the length of the conveying frame 8 and is inclined, the larger fragments that have been vibrated and screened will be discharged to one side through the screen 13, while the smaller fragments will be discharged outward through the conveying frame 8, thereby achieving the purpose of effectively screening the crushed concrete blocks of different sizes.

A plurality of water outlet pipes 43 are fixedly installed on the inner side of the water distribution frame 42. The plurality of water outlet pipes 43 are all fixedly connected to the inner side of the water distribution frame 42, and an atomizing nozzle 44 is fixedly installed at one end of the plurality of water outlet pipes 43.

[0029] During operation, before crushing, firstly, an external water pipe is used to connect to the external pipe 46, and then the water pump 41 is controlled to start. During the start-up process of the water pump 41, the external water source can be transported to the inside of the water distribution rack 42 through the connecting pipe 45. Finally, the internal pressure of the water distribution rack 42 is gradually increased by the continuous delivery of the water source by the water pump 41, and finally, it is sprayed toward the inside of the feed box 3 through the water outlet pipe 43 and the atomizing nozzle 44. The mist water source can, on the one hand, humidify the concrete blocks and reduce the dust generated during crushing, and on the other hand, it can achieve the effect of dust reduction in the crushing process.
