[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones and other waste generated in the production activities of the construction industry, such as demolition, construction, decoration and repair. Construction waste crushing is an important link in the resource utilization of construction waste. Through waste crushing, the volume of waste can be effectively reduced, the resource utilization rate can be improved, and the recycling of resources can be realized.

[0003] Publication No. CN220610577U discloses a construction waste crushing device, including a crushing box with a chute on one side. A crushing mechanism is installed inside the crushing box, comprising two housings. A screening mechanism is located below the crushing mechanism. The two housings are slidably connected within the chute in the crushing box. An adjustment mechanism is located on the other side of each housing. The advantages are: the adjustment mechanism allows for adjustment of the gap between the two crushing rollers when the crushing teeth are worn, ensuring optimal crushing performance; dustproof cloths are installed between the housings and the chute sidewalls of the crushing box, as well as between the two housings, preventing dust generated during crushing from escaping through the gaps; a pointer is fixedly connected to the bottom of one housing, and a scale is provided on the same side of the crushing box, facilitating precise adjustment of the gap between the crushing rollers through the interaction of the pointer and the scale.

[0004] However, after the auger lifts the garbage, it cannot push the garbage out of the connecting pipe. The garbage is easily blocked at the top of the auger due to the upward force, which affects the normal use of the device. At the same time, the stepper motor adjusts the spacing between the crushing rollers, which increases the manufacturing cost. The lead screw is also prone to wear and deformation due to long-term use. Utility Model Content

[0005] The technical problem this utility model aims to solve is that existing construction waste crushing devices used in construction engineering cannot push the waste out of the connecting pipe after the auger lifts the waste. At the same time, the stepper motor adjusts the spacing between the crushing rollers, which increases the manufacturing cost, and the lead screw is also prone to wear and deformation due to long-term use.

[0006] To address the aforementioned problems, this utility model provides a construction waste crushing device for building engineering, comprising a crushing box, crushing mechanisms, and a filter screen. The crushing box has a feeding pipe and a discharge port at its upper and lower ends, respectively. Two crushing mechanisms are located at the upper end of the crushing box.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Combined with appendix Figure 1-4This utility model provides a construction waste crushing device for construction engineering, including a crushing box 1, a crushing mechanism 2, and a filter screen 3. The crushing box 1 has a feeding pipe and a discharge port at its upper and lower ends, respectively. Two crushing mechanisms 2 are located at the upper end of the crushing box 1. Each crushing mechanism 2 includes a housing 21 and a crushing roller 22. A motor is housed inside the housing 21, and the crushing roller 22 is sleeved outside the output shaft of the motor. The filter screen 3 is inserted into one side of the crushing box 1 and located below the crushing mechanism 2. An adjusting groove 11 is provided on one side of the upper end of the crushing box 1. The upper end of the adjusting groove 11 has several limiting grooves 12 adapted to the adjusting component 4. A connecting pipe 13 is provided on the other side of the crushing box 1. A connecting ring 23 is provided at one end of the motor output shaft, and the motor output shaft is rotatably connected to the side of the connecting ring 23. The connecting ring 23 is slidably connected to the connecting pipe 13. An adjusting component 4 is provided at one end of the crushing mechanism 2, and the adjusting component 4 includes an adjusting handle 41. Adjusting rod 42 and limiting block 43 are provided. The two ends of adjusting rod 42 are fixedly connected to adjusting handle 41 and machine box 21 respectively. The upper end of adjusting rod 42 is provided with a slot that is compatible with limiting block 43. Limiting block 43 is fixedly connected to the slot by spring. Limiting block 43 and limiting groove 12 are compatible. When it is necessary to adjust the distance between the two crushing rollers 22, press the limiting block 43 to make it enter the slot. Adjust the position of adjusting rod 42 in adjusting groove 11 by adjusting handle 41. At this time, the connecting ring 23 at the other end of crushing roller 22 slides synchronously on connecting pipe 13. Then release limiting block 43. Limiting block 43 enters the corresponding limiting groove 12 upward by spring action, thus completing the fixation of the position of crushing roller 22. The distance between the two crushing mechanisms 2 can be adjusted manually to reduce manufacturing costs. Limiting block 43 is not easy to wear and is easy to use for a long time because it is in contact with limiting groove 12.

[0024] Combined with appendix Figure 1 , 2 4. A limiting mechanism 5 for limiting the filter screen 3 is provided on one side of the crushing box 1. The limiting mechanism 5 includes a rotating shaft 51 and a connecting plate 52.

After a period of use, by rotating the connecting plate 52, the contact post will no longer limit the filter screen 3. The filter screen 3 can be pulled out by the pull ring provided on one side of the filter screen 3. During this process, the inner wall of the crushing box 1 will scrape the garbage on the filter screen 3 and discharge it from the discharge port. After the staff collects the garbage, it can be poured back into the crushing box 1 for re-crushing.

[0025] The working principle of this application is as follows:

[0026] When it is necessary to adjust the distance between the two crushing rollers 22, press the limiting block 43 to make it enter the slot, and adjust the position of the adjusting rod 42 in the adjusting groove 11 by adjusting the adjusting handle 41. At this time, the connecting ring 23 at the other end of the crushing roller 22 slides synchronously on the connecting pipe 13. Then release the limiting block 43, and the limiting block 43 enters the corresponding limiting groove 12 upward under the action of the spring, thus fixing the position of the crushing roller 22. By manually adjusting the distance between the two crushing mechanisms 2, the manufacturing cost is reduced. The limiting block 43 abuts against the limiting groove 12, and the limiting block 43 is not easy to wear, which is convenient for long-term use. After a period of use, by rotating the connecting plate 52, the abutting column will no longer limit the filter screen 3. The filter screen 3 can be pulled out by the pull ring set on one side of the filter screen 3. During this process, the inner wall of the crushing box 1 will scrape the garbage on the filter screen 3 and discharge it from the discharge port. The staff can collect the garbage and pour it back into the crushing box 1 to crush it again.
