The motor 501 is installed on the frame 4 by screws, one end of the first crushing roller 502 is rotatably connected to the inner wall of the crushing box 1, the other end of the first crushing roller 502 is fixedly connected to the output end of the motor 501 through a coupling, and one end of the second crushing roller 503 is rotatably connected to the inner wall of the crushing box 1. The other end of the second crushing roller 503 penetrates the outside of the crushing box 1 and is fixedly connected with the first gear 504. The connection between the motor 501 and the first crushing roller 502 is provided with a second gear 505. The first gear 504 and the second gear 505 are meshed and connected. A protective mechanism 7 is provided in the feed hopper 2. The protective mechanism 7 includes a protective plate 701 and a spring 703. The protective plate 701 is hinged to the feed hopper 2 through a hinge. A telescopic rod 702 is fixedly connected to the inner wall of the feed hopper 2. The other end of the telescopic rod 702 is hingedly connected to the bottom outer wall of the protective plate 701.

[0025] Start the motor 501, and the motor 501 drives the first crushing roller 502 and the second gear 505 to rotate. Since the first gear 504 is meshed with the second gear 505, it can also drive the second crushing roller 503 to rotate. Then, when the construction waste is poured into the feed hopper 2, the construction waste will come into contact with the protective plate 701, and the protective plate 701 will be driven to open downward by the gravity of the construction waste itself. After opening, the construction waste will fall into the crushing box 1. At this time, the protective plate 701 is not subjected to force, so it will be driven to return to its original position under the elastic action of the spring 703, so that the feed hopper 2 remains in a closed state, thereby preventing the construction debris generated during the crushing process from splashing to the outside world and causing harm to the operator, and also avoiding pollution to the external environment.

[0026] In order to improve the stability of the device during use, Figure 1 As shown, support legs 3 are installed on the bottom outer wall of the crushing box 1 . There are four support legs 3 , and the four support legs 3 are evenly distributed on the bottom outer wall of the crushing box 1 .

[0027] In order to facilitate the collection of building debris, such as Figure 1 As shown, a collecting box 6 is provided in the crushing box 1 , and the opening position of the collecting box 6 corresponds to the unloading position of the crushing mechanism 5 .

[0029] In order to deal with the dust generated during the crushing process, such as Figure 1 As shown, a dust collecting box 8 is provided on the outer wall of the crushing box 1, a dust suction port 9 is provided on the crushing box 1, a dust collector 10 is installed on the top outer wall of the dust collecting box 8, a dust inlet of the dust collector 10 is connected with the dust suction port 9 through a connecting pipe, and a dust outlet of the dust collector 10 is connected with the inside of the dust collecting box 8;

[0030] The vacuum cleaner 10 is started, and the vacuum cleaner 10 sucks the dust generated during the crushing process into the dust collecting box 8 through the dust suction port 9 .

[0031] When in use, start the motor 501, and the motor 501 drives the first crushing roller 502 and the second gear 505 to rotate. Since the first gear 504 is meshed and connected with the second gear 505, the second crushing roller 503 can also be driven to rotate. Then, when the construction waste is poured into the feed hopper 2, the construction waste will contact the protective plate 701, and the protective plate 701 will be driven to open downward by the gravity of the construction waste itself. After opening, the construction waste will fall into the crushing box 1. At this time, the protective plate 701 is not subjected to force, so it will be driven to return to its original position under the elastic action of the spring 703, so that the feed hopper 2 remains in a closed state, thereby preventing the construction debris generated during the crushing process from splashing to the outside. At the same time, the vacuum cleaner 10 can be started. The vacuum cleaner 10 can work to suck the dust generated during the crushing process into the dust collecting box 8 through the dust suction port 9, collect the dust generated during the crushing process, avoid the construction debris and dust from causing harm to the operator, and also avoid pollution to the external environment.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
