[0010] Compared with the prior art, the utility model has the advantages that:

[0011] (1) The utility model discloses a garbage sorting system, which includes screening equipment, crushing equipment, and winnowing equipment. Through the three kinds of equipment, domestic garbage can be classified and processed, and the domestic garbage can be classified into fine garbage, heavy block garbage, and light material garbage, which is beneficial to classified processing and resource utilization.

[0012] (2) The first step of the utility model uses the roller screen to screen the garbage, the roller screen can quickly screen and grade a large amount of garbage, the fine garbage can leak to the lower part of the roller screen, and the large garbage can pass through the screen surface more smoothly under the rotating action of the roller, so that continuous operation can be realized, and the demand of large-scale garbage treatment of the garbage treatment place can be met.

[0013] (3) The second step of the utility model uses the roller crusher to crush the garbage, when the roller crusher works, the garbage is continuously crushed and sent out along with the rotation of the roller, the continuous feeding and crushing mode guarantees the high efficiency of garbage treatment, can adapt to the demand of large-scale garbage treatment, and continuously and stably crushes a large amount of garbage; it has good adaptability, whether it is plastic, wood, fabric in the domestic garbage or brick, concrete block and the like in the construction garbage, can realize crushing under the action of the roller.

[0014] (4) The air separation equipment of the utility model includes two vibration flow guide grooves, and the air separation process of the garbage is greatly optimized; when the crushed garbage enters the air separation equipment, first contacts the first-stage vibration flow guide groove; the flow guide groove makes the garbage preliminarily realize dispersion in the falling process through continuous and regular vibration, avoids the garbage to be concentrated and accumulated, and creates good conditions for the subsequent air separation operation. Subsequently, the garbage slides to the second-stage vibration flow guide groove along the first-stage vibration flow guide groove. The second-stage vibration flow guide groove further adjusts the distribution state of the garbage on the basis of continuing the first-stage dispersion effect, makes the garbage fall more uniformly and loosely, and ensures that each part of the garbage can be fully exposed to the subsequent wind action.

[0015] (5) The utility model sets up the air guide cover of the fan blowing at the upper part of the first vibration flow guide groove, between the first vibration flow guide groove and the second vibration flow guide groove and the lower part of the second vibration flow guide groove, under the action of the three groups of air blowing air guide covers, the wind force generated according to the preset wind speed and wind direction carries out the air separation of the falling garbage. In this process, the lighter garbage material such as paper sheet, plastic film and the like is blown to the first light material garbage conveying belt, the second light material garbage conveying belt and the third light material garbage conveying belt respectively under the action of the wind force, and finally is conveyed to the outside of the air separation room by the third light material garbage conveying belt; and the heavier blocky garbage such as metal block, stone block and the like is less affected by the wind force, continues to keep the relatively vertical falling path and falls into the heavy block garbage hopper, and then is conveyed to the outside of the air separation room by the heavy block garbage conveying belt. After the air separation of the three groups of air blowing air guide covers, the heavy block garbage and the light material garbage can be separated to the maximum extent.
