In the grinding process, the grinding body driving mechanism 231 is started, so that the eccentric wheel 214 rotates under the action of the grinding body driving motor 209, the push rod 212 is pushed to move, then the push rod 212 drives the driving rod 211 to overcome the elastic force of the compression spring 213, the whole driving rod 211 moves towards the direction of the roller 204, and then the whole grinding body 205 is driven to move towards the roller 204, and the grinding of the garbage by the grinding block 207 and the roller 204 is realized; after rolling, as the eccentric wheel 214 continues to rotate to a position far away from the push rod 212, the compression spring 213 rebounds and pushes the driving rod 211, so that the crushing body 205 returns to the original position, and the crushed garbage falls to be rolled again by the lower part or falls into the discharge pipe 230 from the annular discharge hole 203 to be collected.

In this embodiment, the grinding block 207 is designed to be a structure with a wide top and a narrow bottom, so that garbage with a large volume can be gradually ground from top to bottom after entering the garbage grinding cavity 208, and garbage with a small volume can be gradually ground at the lower part of the garbage grinding cavity 208, so that garbage with any volume can be reasonably ground, and compared with the existing method of grinding by two rolling cutters, the method of grinding can enable the garbage to be more sufficiently ground. In addition, the roller 204 is matched with the grinding block 207 to grind the garbage, the grinding process is not complete extrusion grinding, the grinding process is carried out while extrusion grinding is carried out, the grinding degree of the garbage can be greatly improved in the grinding process, so that the garbage can be burnt more efficiently in the follow-up incineration process, the fuel consumption is reduced, the incineration is more sufficient, the slag emission is reduced, and the energy-saving and emission-reducing system can fully achieve the energy-saving and emission-reducing effects.

In summary, the above-mentioned embodiments are only preferred embodiments of the present invention, and all equivalent changes and modifications made in the claims of the present invention should be covered by the claims of the present invention.
