Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing equipment technology, and in particular to a mobile construction solid waste crushing and treatment device. Background Technology
[0002] Construction solid waste refers to solid waste generated during the construction, repair, and demolition of buildings, structures, and pipelines. It includes concrete fragments, bricks, slag, metal, wood, asphalt, mortar, decorative materials, and other waste. Through crushing, the particle size and volume of construction solid waste can be reduced, thereby saving space and costs required for transportation and landfill.
[0003] A search revealed Chinese patent CN216172681U, which discloses a crushing device for treating solid waste from construction concrete. This device addresses the issue of existing crushers that feed concrete into the device through an inlet, where crushing rollers break it down. During crushing, aggregates tend to splash out of the inlet, and the concrete often retains some of the reinforcing steel, requiring secondary screening by the operator. This new device places the concrete on a baffle plate. The weight of the concrete causes the baffle to deflect downwards, allowing the concrete to slide inwards into the crushing chamber. An inclined plate then guides the concrete between two crushing rollers for further crushing. Once the concrete is fully inside the crushing chamber, a spring returns the baffle to its original position, preventing aggregates from splashing out of the inlet. Water mist is sprayed from nozzles to reduce dust generation during crushing. The crushed concrete falls onto a screening plate, separating it from the reinforcing steel, eliminating the need for secondary screening by the operator.
[0004] While the aforementioned device can prevent flying debris, existing technologies for crushing construction solid waste typically only facilitate the crushing of solid waste of the same size. When using crushing rollers designed for crushing small solid waste to crush large solid waste, the distance between the two crushing rollers for small solid waste is too close, making it difficult to capture the large solid waste. Forcibly crushing large solid waste can easily damage the crushing rollers for small solid waste. On the other hand, when using crushing rollers designed for crushing large solid waste to crush small solid waste, the distance between the two crushing rollers for large solid waste is too large, making it difficult to crush the small solid waste effectively. This makes it inconvenient for the device to classify and crush solid waste of different sizes. Utility Model Content

[0034] As attached Figure 1 As shown, the two first gears 8 are meshed together, which facilitates the simultaneous rotation of the two small material crushing rollers 6. One end of the large material crushing roller 7 is fixedly connected to a second gear 9, and the two second gears 9 are meshed together, which facilitates the simultaneous rotation of the two large material crushing rollers 7. The two large material crushing rollers 7 are located on one side of the two small material crushing rollers 6. Two variable speed motors 10 are fixedly installed on one side of the crushing frame 1. One of the second gears 9 is fixedly connected to the output end of one of the variable speed motors 10, and one of the first gears 8 is fixedly connected to the output end of the other variable speed motor 10.
[0035] As attached Figure 3As shown, a partition plate 11 is fixedly connected to the middle of the inner side of the crushing frame 1 to separate the large material crushing roller 7 from the small material crushing roller 6. A guide plate 13 is fixedly connected to the upper surface of the partition plate 11 to guide the large material. A discharge plate 12 is fixedly connected to one side of the guide plate 13, and a discharge chute is opened inside. Baffle plates 14 are fixedly connected to both sides of the inner wall of the crushing frame 1 and one side of the partition plate 11, which helps to prevent materials from getting stuck on both sides of the crushing roller. A hydraulic cylinder 15 is fixedly installed on one side of the crushing frame 1. A push plate 16 is fixedly connected to the output end of the hydraulic cylinder 15. Two limit rods 17 are fixedly connected to one side of the push plate 16 to limit the push plate 16.
[0036] As attached Figure 5 As shown, two through holes 18 are opened on one side of the crushing frame 1, and the limiting rod 17 is slidably connected inside the through hole 18. The limiting rod 17 can move inside the through hole 18 to follow the movement of the push plate 16.
[0037] As attached Figure 2 As shown, a push handle 19 is fixedly connected to the outside of the crushing frame 1 for pushing the device to move. A base plate 20 is provided below the crushing frame 1, and multiple casters 21 are fixedly installed on the lower surface of the base plate 20 to facilitate the movement of the device.
[0038] As attached Figure 1 As shown, a lifting assembly is provided on the upper surface of the base plate 20. The lifting assembly includes a shell rod 25, which is fixedly connected to the upper surface of the base plate 20. A stepper motor 22 is fixedly installed on one side of the feed frame 2. A stud 23 is fixedly connected to the output end of the stepper motor 22 to facilitate the rotation of the stud 23. The shell rod 25 is slidably connected to the outside of the fixed rod 24 to limit the movement of the crushing frame 1.

[0040] Working principle: In use, the two variable speed motors 10 are started first. The output ends of the two variable speed motors 10 drive the corresponding first gear 8 and second gear 9 to rotate. Under the action of the two first gears 8 meshing and the two second gears 9 meshing, the corresponding two small material crushing rollers 6 and large material crushing rollers 7 are driven to rotate relative to each other. Then, the construction solid waste is put into the dropping plate 12 through the feeding frame 2. The small particles will fall between the two small material crushing rollers 6 and be crushed by the small material crushing rollers 6 under the action of the dropping trough in the dropping plate 12. The large particles will be driven by the hydraulic cylinder 15, which drives the push plate 16 to move. The push plate 16 drives the limit rod 17 to slide inside the through hole 18, thereby pushing the large particles. Under the guidance of the guide plate 13, it is easy to push them between the two large material crushing rollers 7 for crushing. Then, the small particles are discharged through the small material discharge frame 4 and the large particles are discharged through the large material discharge frame 5.
[0041] During material discharge, the stepper motor 22 is started according to the height of the receiving frame, so that its output end drives the stud 23 to rotate. Under the action of the threaded groove 27, the stud 23 drives the feeding frame 2 and then drives the crushing frame 1 to move upward. At the same time, the fixing rod 24 slides inside the shell rod 25, thereby widening the gap between the small material discharge frame 4, the large material discharge frame 5 and the bottom plate 20. Then the receiving frame is placed below the corresponding small material discharge frame 4 and large material discharge frame 5 to facilitate material receiving.
