For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0022] As Figures 1-4 shown, a construction waste crushing equipment, including crushing box 1, the inside of the crushing box 1 is provided with a crushing assembly, the crushing assembly includes two crushing rollers 2 rotatingly connected in the inside of the crushing box 1, the two crushing rollers 2 are arranged in parallel, the crushing teeth of the two crushing rollers 2 are staggered with each other, the inside of the crushing box 1 is provided with a return rack 201, the inside of the return rack 201 is fixedly provided with a plurality of filter screens 202, the inner wall of the return rack 201 is fixedly provided with a plurality of supporting plates 203.

[0023] As Figures 1-4As shown, in this embodiment, a first gear 204 is fixed at one end of each of the two crushing rollers 2 extending to the front side of the crushing box 1. The two first gears 204 mesh with each other. A motor is fixed at the front side of the crushing box 1. The output shaft end of the motor is fixed to the side of the first gear 204 near the left side of the crushing roller 2. A second gear 205 is rotatably connected to the front side of the crushing box 1. The second gear 205 meshes with the first gear 204 near the left side of the crushing roller 2.

[0024] like Figures 1-4 As shown, in this embodiment, a support plate 209 is fixed to the left side of the crushing box 1. A drive rod 206 is rotatably connected inside the support plate 209. A third gear 211 is fixed to the front end of the drive rod 206, and the third gear 211 meshes with the second gear 205. A fourth gear 207 is fixed to both the rear end and the outer wall of the drive rod 206. An extension opening 210 is provided on the left side of the crushing box 1 at a position corresponding to the fourth gear 207. Gear rings 208 are fixed to the outer wall of the return rack 201 near both the front and rear sides. The outer wall of the fourth gear 207 passes through the extension opening 210 and meshes with the gear rings 208. The two crushing rollers 2 are driven by a motor to rotate relative to each other, thereby crushing the construction waste. The crushed construction waste is filtered through a filter screen 202. Qualified construction waste will pass through the filter screen 202 and be discharged from the crushing box 1. Unqualified construction waste remains inside the return rack 201. When the motor drives the crushing roller 2 to rotate, the return rack 201 rotates in conjunction with the transmission of the first gear 204, the second gear 205, the third gear 211, and the support gear 3. This causes the construction waste remaining inside the return rack 201 to be lifted by the pallet 203 and transported to the top of the crushing roller 2 by the rotating frame of the return rack 201, where it falls back onto the crushing roller 2 for re-crushing. Simultaneously, the construction waste inside the return rack 201 moves on the filter screen 202 during rotation, increasing the filtration effect of the filter screen 202. This achieves the cyclic crushing of construction waste and ensures the crushing effect. A single motor can drive the crushing roller 2 and the return rack 201 to rotate simultaneously, reducing the cost of the device.

[0025] like Figures 2-4 As shown, in this embodiment, the inner front side of the crushing box 1 near the four corners and the inner rear side near the four corners are rotatably connected to the support gears 3. The support gears 3 mesh with the outer wall of the gear ring 208. By setting the support gears 3, the return rack 201 can be supported and limited, so that the return rack 201 can rotate stably inside the crushing box 1.

[0026] like Figures 2-4As shown, in the embodiment, the outer wall of the return rack 201 is fixed with two blocking rings 4, the blocking ring 4 is in contact with one side of the gear ring 208, by setting the blocking ring 4, the gear ring 208 can be isolated, prevent the construction waste from falling on the gear ring 208 when being screened by the filter screen 202, cause the gear ring 208 and the gear ring 208 to be stuck, so that the device cannot run.

[0027] As shown, Figures 2-4 As shown, in the embodiment, the front side of the crushing box 1 is provided with a feeding hole 5, the inside of the feeding hole 5 is fixed with a feeding hopper 501, by setting the feeding hopper 501, the workers can better put the construction waste into the inside of the crushing box 1.

[0028] From the above description, it can be seen that the embodiment of the utility model realizes the following technical effects: in use, by putting the construction waste from the feeding hopper 501 into the inside of the crushing box 1, then starting the motor to drive the first gear 204 to rotate, under the meshing effect of the two first gears 204, the two opposite first gears 204 rotate and drive the two crushing rollers 2 to rotate oppositely, realize the crushing of the construction waste, in this process, since the first gear 204 meshes with the second gear 205, the second gear 205 meshes with the third gear 211, the third gear 211 and the driving rod 206 rotate synchronously, the fourth gear 207 on the driving rod 206 rotates synchronously, since the fourth gear 207 meshes with the gear ring 208, the return rack 201 and the crushing roller 2 rotate synchronously, the crushed construction waste falls on the filter screen 202, the filter screen 202 filters the construction waste, the qualified construction waste passes through the filter screen 202 and is discharged from the crushing box 1, and the unqualified construction waste remains in the inside of the return rack 201, at the same time, the construction waste in the inside of the return rack 201 moves on the filter screen 202 during the rotation of the return rack 201, the filtering effect of the filter screen 202 can be increased, the unqualified construction waste remaining in the inside of the return rack 201 is conveyed to above the crushing roller 2 under the lifting of the supporting plate 203 and the rotation of the return rack 201 and falls on the crushing roller 2 under the action of gravity and is crushed again, so that the recycling crushing of the construction waste is realized and the crushing effect is ensured, by setting the supporting gear 3, the return rack 201 can be supported and limited, so that the return rack 201 rotates stably in the inside of the crushing box 1, by setting the blocking ring 4, the gear ring 208 can be isolated, prevent the construction waste from falling on the gear ring 208 when being screened by the filter screen 202, cause the gear ring 208 and the gear ring 208 to be stuck, so that the device cannot run.
