It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0043] Embodiment 1:

[0044] The embodiment of the present application provides a concrete regeneration aggregate device, comprising: a main body 1, a feed hopper 2 is arranged on the top of the main body 1;

[0045] It also includes: a crushing chamber 3, which is arranged in the main body 1 and is located below the feed hopper 2; a crushing roller group 4, which includes two crushing rollers 40 rotatably arranged in the crushing chamber 3, and a crushing gap for concrete waste to pass through is provided between the two crushing rollers 40; a crushing chamber 5, which is arranged in the main body 1 and is located below the crushing chamber 3; a crushing roller group 6, which includes a left crushing roller and a right crushing roller, and the left crushing roller and the right crushing roller are both rotatably arranged in the crushing chamber 5; a scraper 7, which is obliquely arranged in the crushing chamber 5, and the lower end of the scraper 7 is tangent to the surface of the left crushing roller; a discharge bucket 8, which is arranged on the left side of the main body 1, and the inlet of the discharge bucket 8 is located below the scraper 7; a recycled aggregate chamber 9, which is arranged at the bottom of the main body 1;

[0046] Among them, the feed hopper 2, the crushing chamber 3, the pulverizing chamber 5 and the recycled aggregate chamber 9 are interconnected, the crushing roller group 4 and the pulverizing roller group 6 can be driven to rotate through the driving member and the transmission member, and an electromagnet is arranged inside the left pulverizing roller.

[0047] Moreover, the driving member and the transmission member are both conventional structures, such as the driving member can be a driving motor, and the transmission member can be a gear transmission structure. Specifically, in this embodiment, the driving motor can be installed on the side of the main body 1, and the driving point of the driving motor is connected to a driving gear. The roller end of the crushing roller 40 or the pulverizing roller is connected to a driven gear meshing with the driving gear.

[0048] The crushing roller 40 further includes: a plurality of crushing rings 400, which are evenly spaced apart along the axial direction of the crushing roller 40 and are concentrically arranged with the crushing roller 40; and a plurality of crushing protrusions 401, which are evenly spaced apart along the circumference of the crushing roller 40 and are located between two adjacent crushing rings 400.

[0049] In this embodiment, the concrete waste is input into the main body 1 through the feed hopper 2, and the concrete waste moves into the crushing chamber 3 after passing through the feed hopper 2. The crushing roller group 4 in the crushing chamber 3 performs preliminary crushing on the concrete waste to separate the concrete from the steel bars. The crushing ring 400 and the crushing protrusion 401 on the crushing roller 40 can further improve the crushing effect of the crushing roller 40 on the concrete waste. Then, the preliminary crushed concrete waste enters the crushing chamber 5 downward, and the crushing roller group 6 further crushes the concrete waste and separates the small pieces of concrete attached to the steel bars. Finally, the concrete waste enters the recycled aggregate chamber 9, and the left crushing roller The separated steel bars are adsorbed by the electromagnet, and the steel bars move to the scraper 7 as the left crushing roller rotates. The scraper 7 scrapes the steel bars off the left crushing roller. At the same time, since the scraper 7 is tilted, the gap between the steel bars and the left crushing roller will gradually increase during the scraping process, thereby reducing the adsorption effect of the electromagnet on the steel bars, ensuring that the steel bars can be fully scraped off. After being scraped off, the steel bars fall downward into the discharge bucket 8. Compared with the prior art, the utility model can fully crush concrete waste to form recycled aggregate, and has a good effect on separating steel bars in concrete waste, effectively reducing the production cost of concrete.

The remaining crushed concrete waste continues to fall downward onto the second screen plate group, and the second screen plate group screens out medium particles in the concrete waste. The remaining small particles finally fall into the recycled aggregate cavity 9. Compared with the prior art, the utility model can effectively grade and screen the crushed concrete waste to obtain recycled aggregates of different sizes, and can also re-crush large particles of recycled aggregate as needed, thereby improving the practicality of the concrete recycled aggregate device.

[0055] Embodiment 3:

[0056] The present embodiment provides a concrete regeneration aggregate device, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features, including: an automatic closing bucket cover 13, which is arranged at the feeding port of the feeding hopper 2, and the automatic closing bucket cover 13 can be opened under the pushing of concrete waste and automatically closed after the pushing is lost.

[0057] The material further comprises: a support rod 14, one end of which is rotatably connected to the inner wall of the feed hopper 2, and the other end of which is rotatably provided with a roller 15; a return spring 16, one end of which is connected to the support rod 14, and the other end of which is connected to the inner wall of the feed hopper 2;

[0060] In this embodiment, the input of concrete waste into the feed hopper 2 causes pushing on the automatic closing bucket cover 13, and the automatic closing bucket cover 13 flips downward after being pushed. At the same time, the roller 15 is also pushed by the automatic closing bucket cover 13, thereby driving the support rod 14 to rotate. The roller 15 can move along the lower surface of the automatic closing bucket cover 13. When the support rod 14 rotates, the reset spring 16 is stretched. After the concrete waste is transported to the feed hopper 2, the automatic closing bucket cover 13 loses external pushing. At this time, the reset spring 16 contracts and drives the support rod 14 to reset. During the reset process of the support rod 14, the roller 15 supports the automatic closing bucket cover 13 to reset and close the opening of the feed hopper 2. Compared with the prior art, the utility model can prevent the dust generated by the crushing in the main body 1 from escaping outward through the feed hopper 2 without affecting the input of concrete waste, and can also block the transmission of noise.
