[0032] like Figures 1 to 3As shown, the embodiment of the present invention provides a construction waste crushing device, including a crushing box 1 and a crushing roller 12, a push-out assembly 2 is installed on the side of the crushing box 1, the push-out assembly 2 is connected to a clamping plate 11, a feed pipe 4 is provided on the top of the crushing box 1, the feed pipe 4 is large at the top and small at the bottom, there are two groups of crushing rollers 12, and the two groups of crushing rollers 12 are provided with multiple groups of evenly distributed crushing teeth 10, a support frame 8 is provided at the bottom of the crushing box 1, and a maintenance door 5 is provided on the side of the crushing box 1 away from the push-out assembly 2. A clamping hole is opened on the surface of the crushing box 1 9. A discharge port 6 is provided at the lower part of the inspection door 5. A guide plate 7 is provided at the lower part of the discharge port 6. The guide plate 7 is fixedly installed inside the crushing box 1. The guide plate 7 is tilted. The guide plate 7 is at the lower part of the discharge port 6 and extends to the inside of the crushing box 1. Two sets of first motors 3 are fixedly and symmetrically installed on the side of the card plate 11 away from the crushing box 1. The first motor 3 is connected to a roller 13. The roller 13 is rotatably connected to the card plate 11. The crushing roller 12 is sleeved on the outside of the roller 13. The side of the crushing roller 12 is provided with a first bolt 14 connected to the roller 13. The card hole 9 is smaller than the card plate 11, and the size of the card hole 9 is larger than the crushing roller 12. When the construction waste is actually crushed, the first motor 3 is started to drive the roller 13 to rotate. The rotation of the roller 13 drives the crushing roller 12 to rotate. The rotation of the crushing roller 12 drives the crushing teeth 10 to rotate, and the construction waste is fed into the crushing box 1 through the feed pipe 4. Under the action of the crushing teeth 10, large particles of construction waste are broken up and crushed. The crushed construction waste falls into the guide plate 7 and is then discharged through the discharge port 6. When the crushing teeth 10 need to be replaced or repaired, the crushing roller 12 is pushed out of the crushing box 1 using the pushing assembly 2, and then placed under the crushing roller 12 using a workbench. Then, the crushing roller 12 is fixed, and the second bolt 206 fixing the connecting plate 207 is released. Then, the crushing teeth 10 on the crushing roller 12 are repaired. When the crushing roller 12 needs to be replaced, the connection between the first bolt 14 and the roller 13 is released, the crushing roller 12 is taken out, and a new crushing roller 12 is inserted. After the repair or replacement is completed, the crushing roller 12 is restored to its original position.

[0033] like Figures 1 to 5As shown, the ejection assembly 2 includes a box body 201, which is fixedly mounted on the side of the crushing box 1. A limiting slot 208 is provided on the side of the box body 201. A second motor 202 is mounted on the side of the box body 201. The second motor 202 is connected to a screw 204. The screw 204 is rotatably connected to the box body 201. The screw 204 is threadedly connected to a moving plate 203. A push plate 205 is connected to the side of the moving plate 203. A connecting plate 207 is engaged with the push plate 205 on the side away from the moving plate 203. The second bolt 206 is threaded through the thread, and the second bolt 206 connects the connecting plate 207 and the push plate 205. The other end of the connecting plate 207 is fixedly connected to the side of the clamping plate 11. The movable plate 203 slides and fits with the limiting groove 208. The second motor 202 is started to drive the screw 204 to rotate. The screw 204 rotates and drives the movable plate 203 to move horizontally along the limiting groove 208. The horizontal movement of the movable plate 203 drives the push plate 205 to move horizontally. The horizontal movement of the push plate 205 drives the connecting plate 207 to move horizontally.

[0034] The working principle of the technical solution provided by the utility model is as follows:

[0035] When the construction waste is actually crushed, the first motor 3 is started to drive the roller 13 to rotate, the rotation of the roller 13 drives the crushing roller 12 to rotate, the rotation of the crushing roller 12 drives the crushing teeth 10 to rotate, and the construction waste is put into the crushing box 1 through the feed pipe 4. Under the action of the crushing teeth 10, large particles of construction waste are broken up and crushed (crushing has coarse crushing and fine crushing, and this device mainly has coarse crushing). The crushed construction waste falls into the guide plate 7 and is then discharged through the discharge port 6. The arrangement of the first motor 3, the crushing roller 12 and the crushing teeth 10 facilitates the crushing of the construction waste, thereby facilitating the next step of utilizing the construction waste.

[0036] When the crushing teeth 10 need to be replaced or repaired, the pushing assembly 2 is used to push the crushing roller 12 out of the crushing box 1. Specifically, the second motor 202 is started to drive the screw 204 to rotate. The rotation of the screw 204 drives the movable plate 203 to move horizontally along the limit groove 208. The movable plate 203 moves horizontally to drive the push plate 205 to move horizontally. The push plate 205 moves horizontally to drive the connecting plate 207 to move horizontally. The connecting plate 207 moves horizontally to drive the card plate 11 to move horizontally. The card plate 11 moves horizontally to drive the crushing teeth 10 and the crushing roller 12 to detach from the inside of the crushing box 1 (the length of the box body 201 is larger than the width of the crushing box 1 to ensure that the crushing roller 12 can be completely detached from the inside of the crushing box 1). Then, a workbench is used to place the crushing teeth 10 and the crushing roller 12 on the crushing box 1. The lower part of the roller 12 (the upper surface of the workbench is in contact with the clamping plate 11), then the crushing roller 12 is fixed, the second bolt 206 is released to fix the connecting plate 207, and then the crushing teeth 10 on the crushing roller 12 are repaired. When the crushing roller 12 needs to be replaced, the connection between the first bolt 14 and the rotating roller 13 is released, the crushing roller 12 is taken out, and the new crushing roller 12 is clamped in. After the repair and replacement are completed, the crushing roller 12 is restored to its original position. Through the setting of the pushing component 2, when the crushing teeth 10 need to be repaired or replaced, the crushing roller 12 can be easily pushed out from the inside of the crushing box 1, thereby providing a larger working space for the operator, facilitating the operator's work, and facilitating replacement and maintenance operations.

To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
