[0021] Example 1

[0022] A waste concrete recycling device comprises a shell 1, wherein the shell 1 is provided with a feed port, a crushing roller 3, a guide cylinder 4, a screening pipe 5 and a collection bucket from top to bottom. The crushing roller 3 is controlled and connected by a first drive motor 2, the driving end of the first drive motor 2 is fixedly mounted on the outer side of the shell 1, and there is a pair of crushing rollers 3, the two groups of crushing rollers 3 are arranged opposite to each other, and gears are mounted on the rotating shafts of the crushing rollers 3. After the two groups of gears are meshed, when the first drive motor 2 rotates to drive the crushing rollers 3 to rotate, the two groups of crushing rollers 3 rotate in opposite directions, so that concrete can be rolled in from the middle of the crushing rollers 3 and crushed.

[0023] A guide cylinder 4 and a screening pipe 5 are arranged in sequence below the crushing roller 3. The screening pipe 5 is arranged at an angle of 5° to the horizontal direction to facilitate the pushing of the material in the screening pipe 5. An opening is arranged at the upper end of the screening pipe 5, and the opening is aligned with the outlet of the guide cylinder 4. A plurality of sieve holes 8 are arranged at the lower end of the screening pipe 5, and the sieve holes 8 are used to screen the concrete fragments crushed by the crushing roller 3. A first auger 7 is installed in the screening pipe 5, and the first auger 7 is connected through a third drive motor 10, and the edge of the first auger 7 fits the screening pipe 5. The fragments that meet the standard size fall into the collection bucket at the bottom of the shell 1 through the sieve hole 8, and the fragments that do not meet the standard size are pushed to the waste material port of the screening pipe 5 by the rotation of the first auger 7. In this way, the screening step of concrete fragments is completed.

[0024] A rotating drum 9 is installed outside the housing 1. The rotating drum 9 has two groups of receiving chambers 11. Both groups of receiving chambers 11 are provided with openings. The receiving chambers 11 are connected to the waste port and the top of the crushing roller 3 through the openings. The rotating drum 9 is connected through the second drive motor 6. A pressure sensor 12 is installed at the bottom of the receiving chamber 11. The pressure sensor 12 is connected to the second drive motor 6 through the controller. The pressure sensor 12 is used as a detection standard to detect the weight of the fragments in the receiving chamber 11 below. When the weight exceeds a certain value, it indicates that the receiving chamber 11 has reached a certain capacity. At this time, the controller controls the second drive motor 6 to rotate, rotate the receiving chamber 11 with a certain capacity to the top, and rotate the empty receiving chamber 11 to the bottom for collection again. The fragments in the receiving chamber 11 that rotates to the top fall through the opening to the top of the crushing roller 3 for secondary crushing. An inclined surface is provided at one end of the receiving chamber 11 close to the second drive motor 6, so that the fragments in the upper receiving chamber 11 can be dumped more smoothly. The controller is connected to the second drive motor 6, and stops the second drive motor 6 during the rotation of the drum 9, thereby preventing the fragments from leaking. During the rotation of the drum 9, the opening of the accommodating chamber 11 is in close contact with the housing 1 to form a closed space, thereby preventing the fragments from leaking from the opening.

[0025] A storage barrel 13 is provided in the housing 1, and the storage barrel 13 is located above the crushing barrel, and the storage barrel 13 is connected to the outlet of the receiving chamber 11. A second auger 15 is provided in the storage barrel 13, and the second auger 15 is connected through a fourth drive motor 14. The secondary crushing of the fragments is a long-term collection, and the one-time feeding is easy to make the material at the crushing roller 3 too much in a short time, which is difficult to handle. The storage barrel 13 is provided between the receiving chamber 11 and the crushing roller 3, and the fragments can be put into the crushing roller 3 in a dispersed manner. The fragments are first stored in the storage barrel 13, and the fragments are evenly put into the crushing roller 3 through the rotation of the first auger 7.

[0026] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
