Technical Field

The utility model belongs to the technical field of garbage collection sorting equipment technique and specifically relates to a bury rubbish classification collection station directly on top.

Background

With the accelerating urbanization process of China, the phenomenon of 'enclosing a city with garbage' is increasingly serious. According to the data of the China Association for urban environmental sanitation, the annual production of domestic garbage in China reaches 440KG, the annual use of plastic snack boxes reaches 40 hundred million in China, instant noodle bowls reaches 7 hundred million, and one-off chopsticks are billion and double, and are continuously increased, wherein about 30% of the domestic garbage can be recycled, recyclable and non-degradable substances are removed, and the quantity of the garbage can be reduced by more than 50%, so that the domestic garbage collection, cleaning and classification are increasingly regarded by people. At present, most of sold garbage collection stations or garbage cans are installed on the ground, the garbage is always overflowed and scattered without being collected due to irregular daily garbage putting amount, secondary pollution can be caused to recyclable garbage if the garrulous garbage is mixed together, the environment pollution caused by odor smoking, sewage cross flow and breeding of rats and insects can be caused after long time or rain is met, the environment of garbage collection points is destroyed, the living environment of citizens is seriously influenced, and the burden of sanitation workers on secondary garbage classification is increased. An underground refuse collection station is a relatively new type of refuse collection station that solves the above-mentioned problems. The existing underground garbage collecting station comprises an outer frame, an inner frame, an elevating mechanism, a garbage can and a landscape feeding box with a feeding port, wherein the outer frame is placed in a pit, the inner frame and the elevating mechanism are arranged in the outer frame, the elevating mechanism drives the inner frame to rise and fall, a cover plate at the top of the outer frame of a sealing cover and a bottom plate used for supporting the garbage can are respectively arranged at the top and the bottom of the inner frame, a blanking port communicated with the landscape feeding box is formed in the cover plate above the opening of the garbage can, and garbage directly falls into the underground garbage can after being fed into the landscape feeding box from the feeding port. The garbage collection station needs cleaning personnel to replace a new garbage can regularly, during replacement, the lifting mechanism is started to lift the inner frame, the garbage can filled with garbage rises to the ground, and after the empty garbage can is replaced, the inner frame is reset, so that the garbage can be continuously used. The refuse collection station of this structure has the following disadvantages: 1. if the garbage can is replaced regularly and the garbage can is filled in the landscape feeding box, the garbage can still be fed in the landscape feeding box, and the garbage can overflow out of the can and is laid on the bottom plate, so that the garbage can is difficult to replace before the garbage overflows, and the subsequent cleaning workload is increased; 2. in severe cases, excessive garbage can be clamped between the bottom plate and the outer frame, so that the inner frame cannot be lifted normally, and the garbage even falls into the outer frame, so that the inner frame cannot be reset normally; 3. when raining, rainwater can form waterlogging from gap entering frame between dog-house or apron and the frame, and cause the damage of equipment easily, and unable normal work.
