[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figures 1-4 A highway dangerous bridge solid waste concrete crusher provided by an embodiment of the utility model comprises a box body 1 and a crushing assembly arranged in the box body 1. A conveyor belt 2 is arranged at the bottom of the box body 1. The highway dangerous bridge solid waste concrete is crushed into highway dangerous bridge solid waste concrete particles by the crushing assembly. The highway dangerous bridge solid waste concrete particles fall onto the conveyor belt 2 at the bottom of the box body 1. Dust suction boxes 5 are arranged on both sides of the box body 1 to absorb and collect the dust generated by crushing the highway dangerous bridge solid waste concrete into highway dangerous bridge solid waste concrete particles, thereby reducing the harm of dust.

[0023] See also Figure 2 , wherein a plurality of magnetic elements 3 are arranged at intervals on the inner side of the conveyor belt 2 along the conveying direction, and each magnetic element 3 is bonded to the inner side of the rubber conveyor belt 2 at equal distances along the conveying direction or is adsorbed to the inner side of the magnetic conveyor belt 2 at equal distances along the conveying direction, and moves with the conveyor belt 2. When each magnetic element 3 is adsorbed to the inner side of the magnetic conveyor belt 2 at equal distances along the conveying direction, a fence corresponding to each magnetic element 3 should be arranged at equal distances on the inner side of the conveyor belt 2 to prevent the magnetic element 3 from being offset when the conveyor belt 2 moves, thereby affecting the adsorption effect. The magnetic suction parts 3 arranged on the inner side of the conveyor belt 2 are used to absorb metal blocks such as steel bars, iron wires, steel plates, etc. in the solid waste concrete particles of dangerous highway bridges that have been crushed by the crushing assembly. When the crushed solid waste concrete particles of dangerous highway bridges are transported to the end of the conveyor belt 2 away from the box body 1, the solid waste concrete particles of dangerous highway bridges that are not absorbed by the magnetic suction parts 3 will fall into the second collecting box 7 directly below the conveyor belt 2 away from the box body 1, while the metal blocks absorbed by the magnetic suction parts 3 are absorbed on the outer surface of the conveyor belt 2, thereby realizing the separation of the metal blocks and the solid waste concrete particles of dangerous highway bridges, so as to facilitate the further processing of the crushed solid waste concrete particles of dangerous highway bridges.

[0024] See also Figure 3 , which also includes a scraper 4, which is located below the transmission belt and is fixedly connected to the box body 1, and is used to scrape the magnetic metal debris blocks adsorbed on the surface of the conveyor belt 2 by the magnetic suction member 3 off the conveyor belt 2 and drop them into the first collecting box 6 just below the scraper 4.

[0025] See also Figure 2and Figure 4 , wherein, as a preferred technical solution of this embodiment, the scraping plate 4 is movably connected to the box body 1 to adjust the distance between the scraping plate 4 and the lower surface of the conveyor belt. This embodiment provides two ways to realize the movable connection of the scraping plate 4 relative to the box body 1. One is that the scraping plate 4 is slidably connected to the box body 1. The implementation method is that a guide rod 8 is fixedly connected to the box body 1, a chute is provided on the guide rod 8, a slider is slidably connected in the chute, the slider is fixedly connected to the scraping plate 4, and a first locking nut 10 is provided at the fixed connection part. The scraping plate 4 is slidably connected to the chute. By sliding the scraping plate 4 on the guide rod 8, the distance between the edge of the scraping plate 4 and the surface of the conveyor belt 2 is adjusted, and the magnetic metal debris blocks adsorbed on the surface of the conveyor belt 2 by the magnetic part 3 are scraped off the conveyor belt 2. The other is that the scraping plate 4 is rotatably connected to the box body 1. The implementation method is that a connecting rod 9 is fixedly connected to the box body 1, and one end of the connecting rod 9 far from the box body 1 is rotatably connected to the scraping plate 4, and a second locking nut 11 is provided at the rotatable connection part. By rotating the scraping plate 4, the distance between the edge of the scraping plate 4 and the surface of the conveyor belt 2 is adjusted, and the magnetic metal debris blocks adsorbed on the surface of the conveyor belt 2 by the magnetic part 3 are scraped off the conveyor belt 2. In addition to the installation method of fixedly installing the above connecting rod 9 or guide rod 8 on the box body 1, the installation method of fixedly installing them on the first aggregate box 6 or the second aggregate box 7 can also be adopted.

[0026] By adjusting the distance between the edge of the scraping plate 4 and the surface of the conveyor belt 2, when the highway dangerous bridge solid waste concrete crusher operates for a long time, the distance between the edge of the scraping plate 4 and the surface of the conveyor belt 2 is increased to scrape off large metal chips, without affecting the conveying function of the conveyor belt 2. When the highway dangerous bridge solid waste concrete crusher is about to end its operation, the distance between the edge of the scraping plate 4 and the surface of the conveyor belt 2 is reduced, so that the edge of the scraping plate 4 contacts the surface of the conveyor belt 2, and the metal chips on the surface of the conveyor belt 2 are scraped clean. At the same time, the wear of the surface of the conveyor belt 2 caused by the long-term contact between the scraping plate 4 and the surface of the conveyor belt 2 can also be reduced.

[0027] Working principle: The highway dangerous bridge solid waste concrete particles crushed by the crushing component fall onto the conveyor belt 2. A plurality of magnetic parts 3 are arranged at intervals along the conveying direction on the inner side of the conveyor belt 2. Each magnetic part 3 is fixedly connected to the inner side of the conveyor belt 2. The magnetic part 3 adsorbs metal chips such as steel bars, iron wires, and steel plates in the highway dangerous bridge solid waste concrete particles and moves together with the conveyor belt 2. When the crushed highway dangerous bridge solid waste concrete particles are conveyed to the end of the conveyor belt 2 far from the box body 1, the highway dangerous bridge solid waste concrete particles not adsorbed by each magnetic part 3 will fall into the second aggregate box 7, while the ones adsorbed by each magnetic part 3 are adsorbed on the outer surface of the conveyor belt 2, realizing the separation of metal chips from the highway dangerous bridge solid waste concrete particles. The metal chips adsorbed on the outer surface of the conveyor belt 2 will be scraped into the first aggregate box 6 by the scraping plate 4 fixedly connected or movably connected to the first aggregate box 6 below the conveyor belt 2.

[0028] The above only describes some exemplary embodiments of the present utility model by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
