In the embodiment of the utility model, the construction waste crushing device includes a crushing box 1, wherein two crushing rollers 2 are horizontally arranged inside the crushing box 1; guide blocks 4 are arranged around the inside of the crushing box 1; an inclined screen plate 5 is arranged inside the crushing box 1 just below the crushing roller 2; support plates 12 are installed on both sides of the inside of the crushing box 1; a screen 13 is arranged on the inclined surface of the support plate 12; a filter plate 14 is installed on the top of the support plate 12; a cleaning mechanism is installed above the filter plate 14; a secondary feeding mechanism is arranged on the right side of the crushing box 1 and communicated with one side of the screen plate 5, and the cleaning mechanism includes a screw rod 7 rotatably arranged inside the crushing box 1; guide rods 8 are horizontally arranged on the front and rear sides of the screw rod 7; a wire sleeve 9 is movably arranged on the outer wall of the screw rod 7 and the guide rod 8; a cleaning brush 10 is installed at the bottom end of the wire sleeve 9; the cleaning brush 10 is in contact with the filter plate 14; the left outer wall of the crushing box 1 A motor 2 11 is installed on the wall; the output end of the motor 2 11 is transmission-connected with the screw rod 7, and the screw rod 7 is threadedly connected with the wire sleeve 9, and the secondary feeding mechanism includes a conveying box 16 arranged on the right side of the crushing box 1; a rotating rod 17 is arranged vertically in the interior of the conveying box 16; a spiral conveying blade 18 is arranged on the outer wall of the rotating rod 17; a feeding pipe 19 is arranged on the upper end side of the conveying box 16; the feeding pipe 19 is connected to the crushing box 1; a motor 3 20 is arranged at the bottom end of the conveying box 16; the output end of the motor 3 20 is transmission-connected with the rotating rod 17, and the central axes of the two crushing rollers 2 penetrate the crushing box 1 and are respectively transmission-connected with the motor 1 3; the two crushing rollers 2 are meshed and rotationally arranged with each other, and a baffle 6 is arranged on the guide block 4 directly below the screen plate 5; the left side of the baffle 6 penetrates the guide block 4 and extends to the outer end of the crushing box 1, and a collecting box 15 is slidingly arranged inside the crushing box 1 below the screen 13 and the filter plate 14.

Usage process:

When in use, construction waste enters the crushing box 1 through the feed port at the top of the crushing box 1, and the motor 3 is started. The two motors 3 rotate relative to each other so that the two crushing rollers 2 rotate in meshing manner, so that the two crushing rollers 2 crush the construction waste. The crushed construction waste falls down and is filtered through the screen plate 5. The filtered construction waste falls onto the filter plate 14 by pulling and removing the baffle plate, and falls into the collection box 15 after being filtered through the filter plate 1. When the construction waste on the screen plate 5 does not fall down, the construction waste slides into the conveying box 16 through the inclined screen plate 5, and the motor 3 20 is started. The motor 3 20 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the spiral conveying blade 18 to rotate, and the uncrushed construction waste is conveyed to the feed pipe 19 through the spiral conveying blade 18, and enters the crushing box 1 again through the feed pipe 19 for The crushing operation is prone to blockage after the filter plate 14 is used for a long time. Start the motor 11, and the motor 11 drives the wire sleeve 9 to rotate, so that the wire sleeve 9 rotates on the screw rod 7, so that the wire sleeve 9 moves horizontally back and forth to clean the construction waste on the filter plate 14, and the garbage is cleaned to slide on both sides and filtered again through the screen 13. The filtered construction waste falls into the collection box 15, and the larger construction waste slides through the inclined screen 13 to the receiving box outside the crushing box 1. The brush repeatedly moves to brush the filter plate 14, which can clean the impurities blocked on the filter plate 14 to both sides, and filter again and move them out of the box, solving the problem of manual garbage cleaning. The filter plate 14 can be cleaned regularly to reduce the blockage of the filter plate 14, prevent blockage from reducing the feeding speed, and improve the filtering efficiency.

In the above process, through the setting of the cleaning mechanism, the cleaning brush moves back and forth on the filter plate, thereby cleaning the blocked filter plate, and the cleaned garbage is filtered and screened again and finally slides to the outside of the crushing box, solving the problem of manual garbage cleaning, facilitating regular cleaning of the filter plate, reducing filter plate blockage, preventing blockage from reducing the feeding speed, and improving the filtration efficiency; through the setting of the secondary feeding mechanism, the uncrushed construction waste can be repeatedly crushed, the crushing rate is improved, and the crushing effect is better; the present application has a simple structure, strong practicality, and simple operation, which is worthy of promotion.

The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
