[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0033] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a steel fiber reinforced concrete crushing and recycling device, comprising a housing 1, a dispensing mechanism installed on the outside of the housing 1, the dispensing mechanism including a conveying component and a dust removal component, a dust removal component installed on the outside of the housing 1, and a crushing component installed inside the housing 1; the dust removal component includes a horizontal plate 5 to prevent the conveyed material from slipping to the side, the horizontal plate 5 is fixedly connected to the outside of the housing 1, and a bottom plate 3 is fixedly connected to the bottom of the horizontal plate 5 to support the entire conveying component and maintain conveying stability; a scraper 26 is fixedly connected to the outside of the bottom plate 3 to scrape off the steel fibers adhering to the magnetic conveyor belt 12. Double-headed bolts 25 are installed on the outside of the base plate 3 to securely fix the scraper 26. The conveying assembly includes a rotating shaft 22, and a magnetic conveyor belt 12 is sleeved on the outside of the rotating shaft 22 to convey the processed materials. A motor 6 is fixedly connected to the outside of the cross plate 5 to provide power to the entire magnetic conveyor belt 12. The rotating shaft 22 is fixedly connected to the output end of the motor 6. Driven by the motor 6, the rotating shaft 22 can be rotated, which in turn drives the entire conveying assembly to run. A support plate 7 is fixedly connected to the outside of the base plate 3. The support plate 7 is located at the bottom of the motor 6 to maintain the stability of the motor during operation.

[0034] Reference Figure 1 A support rod 15 is fixedly connected to the outside of the housing 1. A partition 13 is fixedly connected to one end of the support rod 15 to stabilize the entire partition 13. A spray bar 16 is fixedly connected to the bottom of the partition 13. Several atomizing nozzles 23 are fixedly connected to the bottom of the spray bar 16. A water supply pipe 14 is fixedly connected to the middle of the spray bar 16. Water is transported in through the water supply pipe 14, then enters the spray bar 16, and finally sprays out from the atomizing nozzles 23 to achieve dust suppression.

[0035] Reference Figures 1-3The box 1 has several inclined plates 20 fixedly connected inside, and filter plates 19 fixedly connected inside, which can gather materials together for easy crushing and conveying, and can also screen out qualified and unqualified materials. A feeding plate 24 and a baffle 2 are fixedly connected inside the box 1 to convey the processed materials to the next stage and prevent material leakage. A support column 4 is fixedly connected to the bottom of the base plate 3, and a trapezoidal base 8 is fixedly connected to the bottom of the support column 4 to stabilize the entire device by increasing the bearing area. The crushing component includes a second motor 21, which is fixedly connected to the outside of the box 1. The inside of the box 1 rotates... There are two crushing rollers 17 connected to the moving part, which can finely crush the input material. One end of each crushing roller 17 is equipped with a gear 18, and the two gears 18 mesh with each other. The operation of one crushing roller 17 can drive the operation of the other crushing roller 17 through the gear 18. One end of one crushing roller 17 is fixedly connected to the output end of motor 21. The operation of motor 21 can start the entire crushing assembly. A collection box 10 is set below the horizontal plate 5, which can collect the required material. A handle 11 is fixedly connected to the outside of the collection box 10. A universal wheel 9 is installed at the bottom of the collection box (10) for easy handling and transportation by staff.

[0036] Working principle: First, when using this equipment to separate steel fibers and aggregates, simply start motor 6. At this time, the rotating shaft 22 connected to the output end of motor 6 will rotate and drive the external magnetic conveyor belt 12 to operate. The magnetic conveyor belt 12 will transport the steel fiber concrete that has been screened and crushed. The non-magnetic aggregates will be transported to the next process along with the magnetic conveyor belt 12, while the magnetic steel fibers will be attracted by the magnetic conveyor belt 12 and conveyed downwards. When it is conveyed to the bottom, because there is a scraper 26 at the bottom, the steel fibers that have been conveyed will be scraped off and fall into the collection box 10 placed below.

[0037] Secondly, when the dust is too dense due to the crushing process, water can be introduced into the spray bar 16 through the water supply pipe 14. The spray bar 16 will spray water from the specific atomizing nozzle 23. At this time, since the magnetic conveyor belt 12 below continuously transports the decomposed material, the spray bar 16 can spray the transported material one by one, which not only reduces the dust density, but also cleans the surface of the material appropriately, ensuring the quality of the packaged material.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
