Each crushing component includes two rotating rollers 305 that cooperate to squeeze and grind the construction waste. The external parts of the rotating shaft 303 and the driven shaft 304 are fixedly connected to the interior of the two rotating rollers 305, allowing them to drive the rollers 305 to rotate. Multiple crushing rings 307 are fixedly connected to the exterior of each roller 305.

The outer portion of the transmission column 3014 is slidably connected with an open plate 3015, and the open plate 3015 reciprocates under the drive of the transmission column 3014. The bottom side of the open plate 3015 is fixedly connected with a connecting block 3016, and the bottom side of the connecting block 3016 is fixedly connected with a compression plate 3017. The connecting block 3016 transmits the motion of the open plate 3015 to the compression plate 3017, and the compression plate 3017 is driven by the connecting block 3016 to compress the construction waste. The outer portion of the compression plate 3017 is slidably connected to the inner wall of the collecting box 401, and this sliding connection mode ensures the linear motion of the compression plate 3017 during the compression process. The inner wall bottom end of the crushing box 1 is fixedly connected with an inclined plate 6, which is used for guiding the larger crushed waste out, so as to facilitate secondary crushing;

[0038] The collecting mechanism 4 comprises a collecting box 401, which is used for collecting the treated construction waste and provides a temporary storage space for the waste. The left side of the collecting box 401 is fixedly connected to the right side of the crushing box 1, and the communication between the collecting box 401 and the crushing box 1 facilitates the collection of the waste. The inner wall of the collecting box 401 is slidably connected with a right-angle plate 402 for supporting the compressed waste.

The bottom side of the screening plate 502 is fixedly connected with two concave plates 503, which provide power for the screening of the screening plate 502. The inner walls of the concave plates 503 are fixedly connected with limit columns 504 on the same side, which are used for limiting the movement range of the concave plates 503. The outer portions of the two limit columns 504 are slidably connected to the inner walls of the left and right ends of the circular plates 501, and the rotation of the circular plates 501 drives the screening plate 502 to produce up-down reciprocating motion, thereby realizing the screening function.

[0041] During the crushing process or after the crushing is completed, the crushed construction waste will fall on the screening plate 502, at this time the driven shaft 304 will also drive the driving wheel 308 to rotate, thereby driving the belt 3011 to rotate, in turn driving the driven wheel 3010 to rotate, driving the rotating shaft 309 to rotate through the driven wheel 3010, thereby driving the two circular plates 501 to rotate, at this time the circular plate 501 far from the inside of the center of the circle is fixed with the rotating shaft 309, which makes the circular plate 501 be able to push the two limit columns 504 to slide up and down reciprocating, thereby driving the concave plate 503 to slide up and down reciprocating, in turn driving the screening plate 502 to slide up and down reciprocating, so that the larger construction waste can slide down to be collected, in order to be crushed again, and the smaller construction waste will pass through the vibration of the screening plate 502 and pass through the screening plate 502 and fall on the inclined plate 6, and then through the action of the inclination of the inclined plate 6, the crushed construction waste falls into the inside of the collecting box 401.

[0042] The rotating shaft 309 also drives the rotating plate 3013 to rotate, thereby driving the transmission column 3014 to make circular motion around the rotating shaft 309 as the center, pushing the opening plate 3015 to slide up and down reciprocating through the transmission column 3014, thereby driving the connecting block 3016 to slide up and down reciprocating, in turn driving the compression plate 3017 to slide up and down reciprocating, with the reciprocating sliding of the compression plate 3017, the construction waste in the collecting box 401 is reciprocally compressed, so that the construction waste can be compressed, thereby reducing the vehicles used during transportation, in turn saving transportation cost.
