Description

A kind of garbage sorting recycling and pretreatment device for smart community

technical field

The invention belongs to the technical field of garbage classification, and in particular relates to a garbage classification, recycling and pretreatment device for smart communities.

Background technique

With the rapid development of the economy and the improvement of people's living standards, domestic waste as a product of urban metabolism has become a major problem, and the negative effects brought about by it have gradually emerged, beginning to interfere with the lives of residents and restrict the urban environment. develop.

Since this year, the country has vigorously promoted garbage classification, and the community is also an important area for classification. At present, the garbage classification in the community is mainly based on the setting of different types of garbage cans, which are opened regularly. Such a model will cause many office workers to fail to take into account the time when garbage is placed, so that they cannot throw away the garbage in time, which is very inhumane.

There are also garbage throwing devices suitable for residential areas in the prior art. For example, a low-cost residential garbage sorting and recycling device disclosed by publication number CN207566239U includes a bottom plate, a side plate, a top cover, a public connection plate, a step, and a number of classified and recycled garbage. Buckets and video collectors, the bottom plate is fixed on the ground, the upper surface of the bottom plate is provided with slide rails, the bottoms of the sorting and recycling bins are all mounted on the common connecting plate, and the bottom of the common connecting plate is provided with a sliding rail mounted on the bottom. Several rollers, the two ends of the slide rail are provided with limit parts to prevent the common connection plate from falling off, etc. However, the device can only play the role of sorting and throwing garbage, and cannot pre-treat the garbage, which will reduce the utilization rate of the garbage can, and cannot provide timely disinfection, sterilization and deodorization treatment, and the garbage can will spread germs after a long time. And odor, there are serious hidden dangers for the densely populated communities.

Therefore, combined with the above problems, it is necessary to develop a garbage sorting device that can carry out intelligent management in the community, improve the environmental sanitation of the community, and also increase the garbage capacity and improve the convenience of transportation.

SUMMARY OF THE INVENTION

In view of the above existing technical problems, the present invention provides a garbage sorting, recycling and preprocessing device for smart communities.

The technical scheme of the present invention is: a garbage sorting, recycling and pre-processing device for smart communities, the device includes a base, a support column arranged at the center of the base, a beam laterally arranged on the top of the support column, and a beam fixed above the beam shelter;

Two sets of double guide rails are arranged on the base along the front and rear directions. The two sets of double guide rails are symmetrical about the support column. The middle of each set of double guide rails is provided with a pair of electric push rods in opposite directions. The electric push rods are fixed on the base platform. The electric push rod is movably connected with a trash can. The bottom of the trash can is slidably connected with the double guide rails, and can advance and retreat along the front and rear directions of the abutment under the push of the electric push rod. There is a slope on the outer edge of the abutment, which is convenient for garbage the movement of the barrel;

The bottom of the beam is provided with a garbage pre-processing mechanism that is opposite to the trash can. The garbage pre-treatment mechanism includes a cover connected to the bottom of the beam through a fixing rod. The cover is located directly above the trash can. The cover is a double layer containing a cavity Structure, the cavity is connected with the low-temperature plasma generator arranged in the beam through the hose, which is used to spray the low-temperature plasma gas from the spray nozzle located on the inner wall of the cover to disinfect, sterilize and deodorize the garbage in the trash can. , the garbage pretreatment mechanism also includes an electro-hydraulic push rod fixed under the beam, the lower end of the electro-hydraulic push rod penetrates the cover body and is connected with a pressure plate for compressing the garbage in the trash can;
