After starting the second motor 17, the output end of the second motor 17 can directly drive the crushing roller 15 connected thereto to rotate. The currently rotating crushing roller 15 can drive the other crushing roller 15 to rotate through the two transmission gears 16. At this time, the two crushing rollers 15 rotate in opposite directions to each other, so that the construction waste can be crushed, and the crushed construction waste can fall into the screening box 4 through the first guide hopper 18.

[0028] Embodiment 2: On the basis of Example 1: a plug-in slot 29 is opened on one side of the screening box 4, and a support bar 30 is symmetrically connected to the inside of the screening box 4, and the top of the support bar 30 is flush with the bottom of the plug-in slot 29.

[0032] When the screening frame 31 is installed inside the screening box 4, it is necessary to pull the insertion rod 35 upward through the lever 38 so that the insertion rod 35 is retracted inside the fixed shell 33 to provide space for the screening frame 31. The guide rail 39 is in an inverted L shape. After the lever 38 moves to the top end of the guide rail 39, the inner wall of the guide rail 39 can abut against the lever 38, so that the insertion rod 35 remains in a retracted state. At this time, the screening frame 31 can be directly inserted into the screening box 4. When one side of the screening frame 31 abuts against the inner wall of the screening box 4 After that, the fixed block 40 on the screening frame 31 is just aligned with the fixed shell 33. At this time, the lever 38 can be moved to drive the insertion rod 35 to move. After the lever 38 reaches the bottom end of the guide rail 39, the insertion rod 35 can be inserted into the socket on the fixed block 40. In addition, the spring 37 can apply pressure to the insertion rod 35 through the ring piece 36, so that the insertion rod 35 can be stably inserted into the socket, thereby limiting the screening frame 31 and improving the stability of the screening frame 31 when it is installed inside the screening box 4.

[0033] A bracket 44 is fixedly connected to the top of the base plate 1, and a feed cylinder 19 is arranged on the bracket 44. A second material guide hopper 21 is fixedly connected to the side surface of the feed cylinder 19. The second material guide hopper 21 is inclined and arranged below the screen plate 5. A discharge cylinder 22 is fixedly connected to the side surface of the feed cylinder 19, and the discharge cylinder 22 is located at the top of the crushing box 3.

Under the guidance of the second guide hopper 21, the larger pieces of construction waste can come into the feed barrel 19. At this time, the third motor 23 is started. The output end of the third motor 23 can directly drive the feed shaft 20 inside the feed barrel 19 to rotate. The side surface of the feed shaft 20 is provided with turbine-shaped blades. The blades are in direct contact with the larger pieces of construction waste. When the blades rotate, they can drive the larger pieces of construction waste to move upward. When the larger pieces of construction waste come to the discharge barrel 22 at the top of the feed barrel 19, under the guidance of the discharge barrel 22, these larger pieces of construction waste will fall into the crushing box 3 and be crushed again, thereby improving the crushing effect of the device.

[0036] A cleaning port 24 is provided on the side surface of the feeding barrel 19, a sealing plate 25 is rotatably connected inside the cleaning port 24, a connecting rod 26 is fixedly connected to one side of the sealing plate 25, a clamping plate 27 is rotatably connected to the side surface of the feeding barrel 19, and a clamping port 28 matched with the connecting rod 26 is provided on the clamping plate 27.

[0037] When the device is in use, the sealing plate 25 needs to close the cleaning port 24, and the card plate 27 needs to be rotated so that the card plate 27 can clamp the connecting rod 26 on the sealing plate 25 through the card port 28, thereby restricting the sealing plate 25 to ensure that the sealing plate 25 can stably maintain the current state. When the device is not in use, the card plate 27 can be rotated in the opposite direction to release the restriction on the sealing plate 25, and then the sealing plate 25 can be directly rotated to open the cleaning port 24, so as to facilitate the staff to clean the garbage inside the feed barrel 19.

[0039] After the smaller construction waste reaches the inside of the screening frame 31, the construction waste other than steel and iron metal materials can fall onto the conveying platform 43 through the screening groove 42 on the magnetic plate 32. The conveyor belt on the conveying platform 43 can transport the crushed construction waste to one side of the device, avoiding the crushed construction waste from accumulating at the bottom of the device, thereby making it easier for the staff to handle it.

[0040] Working principle: after adding construction waste into the crushing box 3, start the second motor 17, the output end of the second motor 17 can drive the two crushing rollers 15 to rotate in opposite directions, so as to crush the construction waste in the crushing box 3, and after the crushed construction waste falls into the screening box 4 through the first guide hopper 18, start the first motor 13, the output end of the first motor 13 can drive the second bevel gear 12 to rotate, the rotating second bevel gear 12 can drive the eccentric shaft 8 to rotate through the meshing first bevel gear 11, the rotating eccentric shaft 8 can drive the push rod 10 to reciprocate vertically through the connecting bar 9, and the push rod 10 can drive the screening box 4 to move synchronously through the connecting plate 6 during the vertical reciprocating movement, thereby applying a vibration effect to the screening box 4 to reduce the possibility of blockage of the device. At this time, smaller construction waste The construction waste can fall into the screening frame 31 through the sieve hole 41, and the magnetic plate 32 can absorb the steel and iron metal substances in the construction waste. Then, the construction waste other than the steel and iron metal substances can fall onto the conveying platform 43 through the sieve slot 42 on the magnetic plate 32. The conveyor belt on the conveying platform 43 can convey the crushed construction waste to one side of the device, and the larger construction waste can roll into the second guide hopper 21 and enter the inside of the feed barrel 19. At this time, the third motor 23 is started, and the output end of the third motor 23 can directly drive the feed shaft 20 inside the feed barrel 19 to rotate. The side surface of the feed shaft 20 is provided with turbine-shaped blades. When the blades rotate, they can drive larger pieces of construction waste to move upward, so that the larger pieces of construction waste can fall into the crushing box 3 through the discharge barrel 22 and be crushed again.
