[0002] Solid waste refers to solid and semi-solid items that have lost their original value or have not lost their value but have been discarded in production and life. Unlike wastewater and waste gas, solid waste cannot be migrated and spread everywhere. It must occupy a large amount of land. Every year, 10 million tons of solid waste cannot be processed and piled up into mountains, resulting in a waste of land resources. The main treatment methods are landfill or resource utilization. Solid waste needs to be crushed before treatment, but the existing solid waste crushing devices have many defects and cannot meet the use requirements.

[0004] In the prior art, there is a single crushing bin. This type of structural setting results in low crushing efficiency and poor crushing strength. For the multi-stage crushing structure, most of them are within three stages. During the crushing process, the particles that fall from the first stage to the next stage are crushed again. This structure has the problem that after the crushing at the previous stage, the crushed particles that can be marked will be crushed again at the next stage, resulting in repeated crushing, which leads to the technical problem of slow crushing progress and low efficiency of particles that do not meet the standards.

[0005] Secondly, there is a technical problem that the existing equipment has poor stability in horizontal adjustment. For example, in the prior art, horizontal adjustment is mostly carried out by leveling the crushing equipment using a "raising" leveling method, which has a long operation time and poor stability.

[0006] For this purpose, it is necessary to provide a crushing device for making sand and powder from solid waste. Utility Model Content

[0022] Specifically, in the prior art, there is a single crushing bin. This type of structural setting results in low crushing efficiency and poor crushing strength. For the multi-stage crushing structure, most of them are within three stages. During the crushing process, the particles that fall from the first stage to the next stage are crushed again. This structure has the problem that after the crushing at the previous stage, the crushed particles that can be marked will be crushed again at the next stage, resulting in repeated crushing, which leads to slow crushing progress and low efficiency of the particles that do not meet the standards.

[0023] The structure of the utility model aims to improve the crushing efficiency and achieve the purpose of crushing particles to meet the standards. Specifically, the crushed solid waste is fed through the inlet on the upper part of the primary crushing bin 1 and crushed through the primary crushing bin 1. The qualified particles are screened out from the sieve plate 4 arranged at the bottom of the primary crushing bin 1, and the qualified particles are transported to the conveyor belt 6 for recycling through the inclined baffle 5; the unqualified particles are transported to the secondary crushing bin 2 through the sieve plate 4, and the qualified particles screened out through the sieve plate 4 are transported to the conveyor belt 6 for recycling through the inclined baffle 5, and the unqualified particles are transported to the tertiary crushing bin 3. Similarly, the qualified particles are transported and recycled through the conveyor belt 6, and the unqualified particles or debris are recovered through the conveyor belt 2 7. After screening, the unqualified particles are returned to the primary crushing bin 1 for crushing, thereby completing the sand making and powder making processing of the solid waste.

[0024] In at least one embodiment, the adjustment foot assembly 11 includes a threaded barrel 12, a screw 13, a base 14, a rotating disk 15, and a nut 16. The threaded barrel 12 is arranged at the bottom circumference of the crushing device, and the threaded barrel 12 is connected to the inside of the crushing device. The screw 13 is installed on the internal thread of the threaded barrel 12, and the rotating disk 15 is installed on the middle thread of the screw 13. The nut 16 is integrally arranged on the upper part of the rotating disk 15, and the bottom of the screw 13 is provided with a base; protrusions 17 are evenly arranged on the upper circumference of the base 14, and a limiting groove 21 is arranged on the bottom circumference of the rotating disk 15. The limiting groove 21 is provided with a slide groove 22 in the opposite direction of the rotating disk 15 in the descending state.

[0025] In order to solve the technical problem that the existing equipment has poor stability in adjusting the levelness of the uneven ground of the construction site, in the prior art, the leveling is mostly done by "raising" the crushing equipment, which takes a long time to operate and has poor stability. This patent adopts a threaded adjustment method for leveling, which achieves the characteristics of fast adjustment and stable levelness.

[0026] Specifically, the rotating disk 15 and the screw rod 13 are threadedly arranged to slide to the top of the base 14. A protrusion 17 is arranged above the base 14. During the rotation of the rotating disk 15, the slide groove 22 contacts the protrusion 17 first. As the threaded connection descends, the protrusion 17 slides along the slide groove 22 and slides into the inside of the limiting groove 21. The protrusion 17 is clamped by the limiting groove 21, so that the rotating disk 15 drives the base 14 to rotate, and the screw rod 13 is threadedly rotated in the threaded barrel 12 to achieve the height adjustment and leveling setting of the crushing device. After the horizontal adjustment is completed, the rotating disk 15 is reversed, and the protrusion 17 slides out of the limiting groove 21 and rotates out along the slide groove 22. At this time, the rotating disk 15 continues to be rotated, so that the nut 16 arranged on the upper part of the rotating disk 15 is fastened and installed with the bottom of the threaded barrel 12, so as to achieve the horizontal fixation of the crushing device and complete the stable horizontal adjustment.

[0027] In at least one embodiment, in order to enable the rotating disk 15 to be quickly adjusted to above the base 14, a slope structure 23 is provided inside the slide groove 22, and the height of the slope structure 23 is gradually decreased along the rotation direction of the rotating disk 15 in the descending state. The protrusion 17 can slide smoothly along the slope structure 23 and engage with the limit groove 21 to limit, or slide out.

[0028] In at least one embodiment, the angle between the sieve plate 4 and the inclined baffle 5 is 20 degrees to 60 degrees, preferably 45 degrees, at which time the screening is uniform and the particle flow is stable.

[0029] The embodiments of the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent alternatives that can be thought of by those skilled in the art are all within the protection scope of the present invention.
