Problems solved by technology
However, because this type of warehouse door has a certain degree of freedom of rotation, dirt is easily embedded between it and the door frame, resulting in seal failure
On the other hand, if multiple garbage tunnel bins are arranged together, the push-pull structure on both sides will inevitably cause the adjacent bin doors to conflict with each other.
It should be noted that there are generally at least 15 tunnel bins for domestic waste composting at present, and the problem of opening and closing conflicts near the bin doors must be considered

Embodiment Construction
[0040] Refer to attached figure 1 , each fermentation bin 10 is equipped with a pair of bin doors, i.e. the upper bin door and the lower bin door shown in the figure, each bin door is provided with three pairs of door shafts 12, and correspondingly three pairs of supporting hooks 13 are provided on the fermentation bin.
[0041] The effect of supporting hook 13 is supporting, and owing to need sealing, decoupling should have an inward guiding force, makes storehouse door can rely on self-weight to compress fermentation storehouse doorframe inwardly. The inward here is the normal direction to compress the door frame of the fermentation bin. image 3 It clearly reflects the structure of the hook.
[0042] According to the above structure, a hydraulic door opener is applied to the door with horizontal door shafts on both sides of the frame and relies on the supporting hook 13 to support the corresponding horizontal door shaft to realize closing. A working slope extending downw...

The invention discloses a hydraulic door opener, which is applied to a warehouse door, wherein horizontal door shafts are arranged on borders on two sides of the warehouse door, and tow hooks support the corresponding horizontal door shafts so as to realize closing of the warehouse door. Each tow hook is provided with a working inclined plane which downwards and inwards extends in a vertical normal plane of the warehouse door. The hydraulic door opener comprises a rack, two levers, a hydraulic driver, a manual oil pump, a support, a guide track and hand-operated running trolleys, the rack is parallel to the warehouse door when used, the left and the right of the rack are symmetrical, the two levers are respectively disposed on two sides of the rack, a rotating plane is the vertical normal plane of the warehouse door, an upward hook is disposed at an end on each side of the warehouse door, so that the hooks exactly hook the horizontal door shafts on the corresponding sides when the levers are located horizontally, the guide track is mounted on the support, is parallel to the upper border on the warehouse door and extends towards at least one side, the hand-operated running vehicles operate on the guide track, and the rack is hung on the hand-operated running vehicles. The hydraulic door opener brings convenience for opening the warehouse door.
Description
[0001] technical field [0002] The invention relates to a door opener, which is used for opening the door of a tunnel bin in a domestic garbage composting system. Background technique [0003] Because the hydraulic door opener in the present invention has its specific application, here at first explain the general structure of the tunnel bin door in the household waste composting system. The composting of domestic garbage tunnel warehouse (hereinafter referred to as the warehouse door) has the characteristics of large processing capacity, short aerobic fermentation cycle, and the storage space requires a relatively good seal. It is necessary to ensure that the odor is not leaked, making the warehouse door one of the key components. For example, some warehouse doors have a size of about 6x6 meters and a weight of 500-600 kg. The individual is relatively large. The structure itself and the opening and closing method will have a relatively large impact on the sealing effect an...
