Description

Technical Field

[0001] This invention relates to the field of solid waste technology, and more specifically to a shearing and crushing mechanism based on an orthogonal layout. Background Technology

[0002] Solid waste treatment is a crucial link in environmental protection and resource recycling. As the core equipment for front-end processing, crushing equipment directly affects the efficiency of subsequent sorting, recycling, and disposal. Existing crushing equipment (such as jaw crushers, cone crushers, and twin-shaft shear crushers) generally suffers from problems such as poor uniformity of output particles, large footprint, and the need to replace equipment for multi-stage crushing.

[0003] Patent CN115445719A discloses a crushing device for aluminum shearing. Through a refeeding structure, it can perform repeated crushing to improve the uniformity of particle size. While this invention solves some of the particle uniformity issues, the orientation of the material entering the equipment may still affect the crushing effect and efficiency. Patent CN121087817A discloses a waste paper raw material crushing device. Through a three-stage series crushing design (biaxial shearing coarse crushing → high-speed single-axis shearing fine crushing → hammer mill fine crushing), it achieves progressive crushing of waste paper. Although this method can achieve multi-stage crushing and reuse of materials to some extent, it is applicable to materials without hard metals, such as plastics, textiles, and wood, and is not suitable for crushing solid metals. Furthermore, traditional crushing mechanisms rely on gravity for material feeding after shearing, and cannot function properly in microgravity environments.

[0004] To address the aforementioned shortcomings, this invention proposes a modular mechanism that integrates feeding, dual-shaft coarse crushing, and screw multi-stage fine crushing. It adopts an orthogonal layout to achieve directional particle conveying and multi-stage shearing in a microgravity environment. Summary of the Invention

At the same time, the screw assembly 308 drives the sweeping rod 307 to rotate, collecting the material after being coarsely crushed by the dual-axis shearing module 2 into the inside of the barrel 301 and causing it to fall between the two screw assemblies 308. During this process, the sweeping motor 314 drives the sweeping screw 309 to rotate, cooperating with the sweeping rod 307 to further improve working efficiency. The discharge motor 316 drives the discharge screw 315 to rotate, improving the discharge efficiency.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that the screw assembly 308 is divided into three regions along the axial direction: an upper region, a middle region, and a lower region, which are respectively a feeding region, a weak shearing region, and a strong shearing region. The upper feeding region has a traditional spiral structure for conveying materials. The middle weak shearing region is equipped with weak shearing elements, which are splined onto the screw shaft of the screw assembly 308 and arranged at a set spiral angle for the first stage of shearing of the materials. The lower strong shearing region is equipped with strong shearing elements, which are installed in the same way as the weak shearing elements, for further crushing of the materials. In use, the screw module motor 306 drives the second pulley 303 to rotate through the screw module reducer 302. The second pulley 303 drives the first pulley 304 through the synchronous belt 311. The first pulley 304 drives the screw assembly 308 to rotate. At the same time, the screw assembly 308 drives the sweeping rod 307 to rotate, thus crushing the materials after dual-axis shearing. After coarse crushing in Module 2, the material is fed into the feed hole of the barrel 301 through the sweeping rod 307 and finally falls between the two screw assemblies 308. Due to the characteristics of the screw assembly 308 itself, the crushed material is continuously conveyed downwards, entering the upper feeding zone of the screw assembly 308 to complete the first crushing, then being conveyed to the middle weak shear zone for the second crushing, and finally being conveyed to the lower strong shear zone of the screw assembly 308 for the final crushing. This ensures that the crushed material can be fully crushed into particles with high uniformity. Particles that meet the size requirements can pass through the gaps between the two screw assemblies 308 and between the screw assembly 308 and the inner wall of the barrel 301, and are conveyed out through the discharge screw 315 from the discharge hole at the bottom of the barrel 301, realizing multi-stage crushing of the crushed material. During this process, the sweeping motor 314 drives the sweeping screw 309 to rotate, cooperating with the sweeping rod 307 to further improve working efficiency.

Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
