Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crusher capable of pre-screening metallurgical waste residues. Background Art

[0002] A crusher is a kind of machine equipment that can crush or grind solid materials to make them finer or smaller. Crushers are widely used in industries such as mining, construction, metallurgy, railway, and cement. There will be larger-sized waste residues in metallurgical waste residues. Direct crushing will damage the crusher, so it is necessary to pre-screen the larger waste residues in advance.

[0003] The Chinese utility model patent discloses a crushing device for metallurgical slag processing (authorization publication number: CN210646619U), which includes a crusher, a crushing plate, and bolts. A driving motor is fixedly installed in the middle of the bottom of the inner cavity of the crusher. For this crushing device for metallurgical slag processing, by installing a driving motor at the bottom of the crusher, the top of the driving motor is connected to a threaded rod. A lifting tube is movably sleeved on the outer surface of the threaded rod. Connecting rods are welded to the left and right sides of the lifting tube. The other ends of the connecting rods are fixedly connected to sliders on the outer surface of the slide rail. At the same time, support rods are installed at the tops of both connecting rods. The top end of the support rod is connected to a screening plate. When the driving motor is started, the left and right rotation of the threaded rod can drive the up and down movement of the lifting tube, and the screening plate will also move synchronously with the up and down movement of the lifting tube, thereby changing the distance between the hammer head and the screening plate, facilitating the selection of crushed materials with different diameters, and meeting various requirements of the factory.

[0004] For the above-mentioned existing technology, there are the following problems:

[0005] During the use of this existing technology, since this device filters metallurgical waste residues through a filter screen, leaving the larger waste residues inside the filter screen. However, the area of the filter screen is limited. The large waste residues remaining on the surface of the filter screen will block the screening openings, and it is necessary to clean up the large waste residues before continuing the screening. When the amount of waste residues is large, frequent manual cleaning is required, which not only consumes labor but also affects work efficiency. Therefore, it is necessary to improve a crusher capable of pre-screening metallurgical waste residues to solve the above problems. Summary of the Utility Model

[0028] In this embodiment, the screening mechanism 2 includes a screening component 21 and a collection component 22.

The screening component 21 includes a first motor 211, the first motor 211 is fixedly connected to the right side of the crushing box 1, the output end of the first motor 211 is fixedly connected with a cam 212, a slide rail 213 is fixedly connected inside the crushing box 1, a slide bar 214 is slidably connected inside the slide rail 213, a first spring 215 is fixedly connected between the slide bar 214 and the slide rail 213, and a screening frame 216 is fixedly connected to the inner side of the slide bar 214. By shaking the screening frame 216, waste residues of different sizes are separated to prevent waste residues with larger sizes from entering and damaging the device.

[0029] There are two slide rails 213, and the two slide rails 213 are symmetrically and fixedly connected inside the crushing box 1. The cam 212 is in contact with the screening frame 216. The screening frame 216 is limited by the slide bar 214 so that the screening frame 216 can only move linearly to prevent the screening frame 216 from shifting. A through groove is opened at the corresponding position of the crushing box 1 for the screening frame 216, and the screening frame 216 passes through the through groove. The screening frame 216 passing through the through groove facilitates the discharge of larger waste residues for subsequent treatment. The collection component 22 includes a mounting frame 221, the mounting frame 221 is fixedly connected to the right side of the crushing box 1, a collection box 222 is movably connected inside the mounting frame 221, a clamping rod 223 is slidably connected inside the mounting frame 221, a connecting disc 224 is fixedly connected to the top of the clamping rod 223, a second spring 225 is fixedly connected between the connecting disc 224 and the mounting frame 221, and a pull ring 226 is fixedly connected to the top of the connecting disc 224.

The second spring 225 is used for the reset of the connecting disk 224, so that the clamping rod 223 disengages from the clamping hole of the collection box 222. Then the collection box 222 can be taken out from the inside of the mounting frame 221, so as to process the larger waste residue. The smaller waste residue enters between the two crushing rollers 34 through the guide of the crushing box 1. The second motor 31 drives the rotating roller 32, the rotating roller 32 drives the gear 33, and the gear 33 drives another gear 33, so that the two rotating rollers 32 rotate synchronously.
