[0002] It is generally believed that restaurant kitchen waste comes from the waste generated by residents in their daily lives. In recent years, with the rapid development of my country's economy and the improvement of people's living standards, the amount of restaurant kitchen waste has continued to increase, and the resulting environmental pollution problem has become increasingly serious. How to effectively deal with restaurant kitchen waste has become a major environmental problem that must be faced at home and abroad.

[0003] Before disposing of kitchen waste, it is necessary to unload and pre-treat it. There are a lot of plastic bags in the kitchen, and a lot of kitchen waste is still in the plastic bags. If you need to deal with the waste, you need to break the bags so that the waste in the bags can come out. Therefore, the first step of pre-treatment is to break the plastic bags in the waste and remove the heavy materials (metal, sand, etc.) in the kitchen waste to facilitate the next step and ensure the smooth progress of the subsequent steps. Summary of the invention

[0004] The invention provides a bag breaking and sorting machine for kitchen garbage, which solves the technical problem that the device using water flow to break garbage bags in the prior art is relatively complicated.

[0006] The tank body comprises a conical spiral, and the conical spiral comprises a main shaft. The upper end of the main shaft is connected to a reduction motor, and the lower end is connected to a spiral main shaft. The spiral main shaft has conical spiral blades, and the unfolded size of the spiral blades gradually decreases from top to bottom. A spiral blade is arranged on the outer edge of the spiral blade.

[0007] As a preferred embodiment, a semicircular baffle is provided at the light material discharge port, the bending direction of the baffle is opposite to the rotation direction of the conical screw, and the baffle is provided with a plurality of small holes.

[0008] As a preferred embodiment, the tank body is provided with two symmetrical light material discharge ports.

[0009] As a preferred embodiment, the outer edge of the spiral blade is wavy, and the concave portion of the spiral blade is provided with a spiral blade.

[0010] As a preferred embodiment, a main discharge pipe is provided at the main discharge port, and the main discharge pipe extends from the inside of the tank body to the outside of the tank body, and the top end of the main discharge pipe is higher than the inner surface of the bottom end of the tank body.
