Environmental pollution is always a problem troubling people, and the recovery of garbage plays a key role in environmental protection. People throw the garbage into the garbage can at any time in life, and some garbage is valuable, people can trade money equivalent to the value of the garbage by picking and selling the garbage, meanwhile, the enthusiasm of people for recycling the garbage can be mobilized, the garbage is thrown into the garbage can, good environmental awareness and habits are developed, and therefore the environment protection is positively promoted.

The existing garbage can is mostly of a single cylindrical structure, and garbage can be directly thrown into the garbage can when the garbage can is used. With the development of society, the importance of garbage classification is more and more recognized by people, and as garbage is divided into two types, namely recyclable type and non-recyclable type, people design garbage cans into recyclable and non-recyclable garbage cans, so that the garbage can is beneficial to recycling of the garbage and meanwhile, the environmental pollution is reduced. However, in the actual life, people are not so clear to the classification of rubbish, often the wrong throw in recoverable garbage bin with unrecoverable rubbish, throw in unrecoverable garbage bin with recoverable rubbish, so not only cause very big pollution for can become can not recycle by the rubbish of retrieving recycling, the resource has been wasted, and it is troublesome to cause unnecessary for later stage rubbish letter sorting work moreover, has increased letter sorting work volume.

In addition, the existing garbage sorting method mainly relies on manual sorting, and has the disadvantages of low sorting speed, high labor intensity and poor working environment sanitary condition.

In summary, a fully automatic material classifying and recycling device is urgently needed.
