With the development of society and the continuous improvement of people's living standards, the amount of domestic waste is constantly increasing. At present, there are almost no mechanical products on the market for waste sorting and most waste transfer stations use manual sorting. In this article we will introduce a waste bin that can sort waste intelligently. This product intelligently identifies the waste put in, matches it with the information in the database, determines the type of waste and puts it into the appropriate bin. The device also has a conveyor belt and a laser distance measuring device. When several pieces of rubbish are put on the conveyor belt together, the laser distance measuring device will intelligently determine the quantity and position of the rubbish and the mechanical claws will sort the rubbish out, identifying and sorting it in turn. This ensures that the waste enters the waste portal one by one and enables precise sorting of individual waste. This has the effect of intelligently sorting the waste. The device also has an ultrasonic full detection module, which alerts people to change their rubbish bags when the bin is full, so that residents can simply put the appropriate rubbish bag into the corresponding bin at the rubbish drop-off point, saving time and reducing the sorting pressure at the city transfer station (Qu 2011).
