Description

Garbage truck docking system

technical field

The utility model relates to the field of sanitation machinery, in particular to the non-leakage docking of large garbage trucks and small garbage trucks.

Background technique

With the rapid expansion of cities in our country and the rapid increase of urban population, the problem of urban domestic waste is becoming more and more serious, which directly affects the life and environment of urban people. At present, the collection and treatment mode of most urban garbage is: garbage can→garbage collection truck→garbage transfer station→outside the city garbage disposal site. However, setting up garbage transfer stations in cities will not only occupy a large amount of land, but also seriously affect the surrounding environmental sanitation, which is increasingly opposed by the public.

As a result, practitioners at home and abroad have proposed the technical concept of docking garbage trucks. Large garbage trucks replace traditional garbage transfer stations. Small garbage trucks collect garbage in garbage bins along the road. After they are full, they dock with large garbage trucks and transfer the garbage to Large garbage trucks, and finally the large garbage trucks are filled and transported to garbage disposal sites outside the city for disposal. However, the design of existing large and small garbage trucks does not consider the leakage of garbage during docking, and the process of docking and transferring garbage between large and small garbage trucks often causes secondary pollution.

Utility model content

In view of this, a non-leakage garbage truck docking system is provided to avoid secondary pollution when docking and transferring garbage.

A garbage truck docking system includes a small garbage truck and a large garbage truck, the small garbage truck is used to collect garbage in garbage bins along the road, the large garbage truck is used to transfer the garbage in the small garbage truck, and the tail end of the small garbage truck is Open and coupled with a rear door, the tail of the bottom plate of the compartment of the small garbage truck is tilted upwards, the rear end of the compartment of the large garbage truck is open and coupled with a rear door, when the small garbage truck docks with the large garbage truck to transfer garbage, the large garbage The rear door of the car is opened, the rear door of the small garbage truck is opened, and the tail end of the compartment of the small garbage truck extends into the compartment of the large garbage truck to form a seamless connection.

Compared with the prior art, in the garbage truck docking system of the utility model, the tail of the bottom plate of the compartment of the small garbage truck is tilted up, which facilitates the insertion of the tail end of the compartment of the small garbage truck into the compartment of the large garbage truck to form a seamless docking, To avoid garbage leakage from the gap between the docking vehicles, causing secondary pollution. In addition, there is no need to set up garbage transfer stations in the city. On the one hand, it can reduce the occupation of urban land, and on the other hand, it can beautify the urban environment.
