Reasonable recycling and use of urban garbage can create greater value and have far-reaching significance for resource utilization and environmental protection. Garbage classification and recycling are mainly divided into the following four categories: recyclable materials, hazardous waste, kitchen waste and other waste. However, the mechanism of garbage classification and treatment in China is not perfect, and the environmental sanitation system is disjointed in terms of garbage classification supporting facilities and operation management. The main problems are as follows: (1) Although the state has vigorously advocated garbage classification, mixed collection still exists in the process of garbage truck transfer and recycling, on the one hand, making garbage classification an "empty talk", and on the other hand, making the utilization rate of useful garbage low, which is a waste of resources; (2) The garbage cans used on urban roads are mostly split type, and there is a gap between the shell and the inner cylinder of the split type garbage can, and garbage is easy to be thrown outside the cylinder; (3) The garbage recycling process in urban roads and parks, schools and other places mainly relies on manual cleaning, which is labor-intensive, low-efficiency, and there is a phenomenon of garbage scattering during garbage dumping; (4) The stubborn stains inside the garbage can are difficult to clean thoroughly, breed bacteria and easily corrode and damage the garbage can. In view of the above problems, the present application designs a garbage cleaning and transporting vehicle based on pneumatic conveying technology and a garbage can, aiming to solve the problems of the split structure of traditional garbage cans, unclassified garbage in the process of vehicle transfer, labor-intensive manual cleaning, low efficiency, residual stains in the garbage can and other problems.
