Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to an external auxiliary door opening and closing device for a top door of a garbage transfer box applied to a vertically split horizontally compressed garbage station. Background Art

[0002] In the existing vertical garbage compression stations, the garbage transfer box is fed from the top of the box. To ensure the closed transportation of garbage, a top door is designed on the top of the box, and the top door is opened and closed by a cylinder. Considering the factors such as reducing the weight of the transportation equipment to load more goods and improving the transportation efficiency, the garbage transfer box is generally not equipped with a driving power unit. Therefore, to drive the box top door cylinder, only a quick-change joint can be used to connect the cylinder pipeline. The quick-change joint is connected to the hydraulic power source. The hydraulic energy delivered by the power unit drives the top door opening and closing cylinder on the box to drive the box top door opening and closing. The problems with this technology are:

[0003] (1) After the vertical garbage transfer box enters the station, it is necessary to manually plug in the quick-change connector. When the garbage transfer box leaves the station, it is necessary to manually separate the quick-change connector from the box. If the quick-change connector is not unplugged when leaving the station due to carelessness, it will cause the power unit to be pulled out and the pipeline to be damaged. On the other hand, the working environment of the garbage station is harsh. This link is manually operated and cannot be automated. The garbage station is unmanned;

[0004] (2) Due to the design of the quick-change joint, it is inevitable that the hydraulic oil in the joint will leak out when the quick-change joint is removed, thereby polluting the environment and wasting hydraulic oil;

[0005] (3) The oil cylinder has a certain weight. When transported with the garbage container, it will increase the weight of the container itself. Under limited load transportation conditions, the amount of garbage transported will be reduced, thereby increasing the transportation cost.

[0006] (4) Each vertical garbage transfer box is equipped with a door opening and closing cylinder, which increases the cost of the box and causes waste of resources. Summary of the invention

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an external auxiliary switch device for the top door of a garbage transfer box, so as to realize automatic opening and closing of the top door of the garbage transfer box, with high operating efficiency, energy saving and environmental protection.

[0008] The purpose of the utility model is achieved in this way:

[0009] A garbage transfer box top door external auxiliary switch device comprises a garbage transfer box, the garbage transfer box has a garbage transfer box top door, and also comprises a top door external auxiliary switch device, the top door external auxiliary switch device has a box top door moving frame base, the box top door moving frame base has an entrance space for the garbage transfer box, the top of the box top door moving frame base slides longitudinally and is cooperated with the box body top door moving frame, a door opening and closing oil cylinder is connected between the box body top door moving frame and the box top door moving frame base, the door opening and closing oil cylinder is used to drive the box body top door moving frame to move forward and backward, a lock plate driving cylinder is vertically installed on the box body top door moving frame, a box body top door lock plate is installed on the lock plate driving cylinder, the lock plate driving cylinder is used to drive the box body top door lock plate to swing up and down, a garbage transfer box top door lock slot is installed on the garbage transfer box top door, the box body top door lock plate is used to be clamped with the garbage transfer box top door lock slot, and the door opening and closing oil cylinder is used to drive the garbage transfer box top door.

[0010] Preferably, the door opening and closing cylinder adopts a segmented two-stage cylinder.

[0011] Preferably, a box position sensor is installed on the base of the top door movable frame, and a box position sensing piece is correspondingly provided on the garbage transfer box. The box position sensor is used to sense the placement status of the garbage transfer box through the box position sensing piece.

[0012] Preferably, a top door position sensor is provided on the moving frame of the box top door, and a top door position sensing piece is correspondingly provided on the top door of the garbage transfer box. The top door position sensor is used to sense the position status of the top door of the garbage transfer box through the top door position sensing piece, and automatically find the top door lock slot of the garbage transfer box corresponding to the top door lock plate of the box body.

[0013] Preferably, a top door magnetic lock is provided on the top door of the garbage transfer box, and a top door magnetic lock column is provided on the garbage transfer box. When the top door of the garbage transfer box is in a closed state, the top door magnetic lock column and the top door magnetic lock are in an attracted state to lock the top door.

[0014] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0015] 1. The top door switch does not require quick-change connectors for plugging and unplugging, which is highly efficient, safe and reliable;

[0016] 2. Since the quick-change joint plug-in operation is cancelled, there is no oil leakage pollution and oil waste from the quick-change joint, which is energy-saving and environmentally friendly;

[0017] 3. It can realize the automated operation of garbage transfer boxes and enable unmanned operation of garbage transfer stations 24 hours a day.

[0018] 4. The driving cylinder of the top door of the garbage transfer box is cancelled, which reduces the weight of the garbage transfer box. Under limited load conditions, the loading capacity of the garbage box is increased, thereby improving the garbage transfer efficiency and reducing the manufacturing cost of the garbage transfer box.
