Abstract
The utility model discloses a locking device of a road sweeper dustbin door. The locking device of the road sweeper dustbin door comprises a door opening link mechanism, a locking cylinder (5) and a latch hook (6), wherein the door opening link mechanism consists of a dustbin (7), a door opening cylinder (1),a rocker panel (2), a draw rod (3) and a door body (4), one end of the locking cylinder is hinged with the dustbin, the other end of the locking cylinder is hinged with the latch hook, and the latch hook is hinged with the dustbin to form a door locking link mechanism. According to the technical scheme of the utility model, the door locking link mechanism is pushed by the locking cylinder, and a door frame of the door body is locked by the latch hook, so that a seam does not exist between the door body and the dustbin, secondary pollution on the road surface caused by muddy water mixture drippage is prevented, and the cleanness of the environment is kept. A hydraulic system is used, so that the structure is compact, and the fault rate is reduced.
Description
Technical field
The present invention relates to a kind of cleaning sweeper, relate in particular to the suction garbage can door locking device of cleaning sweeper.
Background technology
At present, the locking mode of latch in the middle of an oil cylinder pushed away in the middle of road-sweeper and cleaning sweeper back door of rubbish bin locking adopted mostly in the environmental sanitation vehicles is because Men Tida; Planeness is difficult to guarantee, causes having the slit between the Men Tiyu dustbin, and the door body can't be locked; Be that muddy water mixes in the dustbin; Occur in the rubbish process leaking with transporting in the cleaning gap, environment is caused secondary pollution, influenced the clean and tidy of road surface.
Summary of the invention
Goal of the invention: the objective of the invention is to deficiency to prior art; Providing a kind of can lock the suction garbage can door body; Seamless between the Men Tiyu dustbin, the road surface that protection was fully swept clean and tidy prevents the cleaning sweeper suction garbage can door locking device of secondary pollution.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the present invention adopted is:
A kind of cleaning sweeper suction garbage can door locking device; The linkage that opens the door that comprise dustbin, the oil cylinder that opens the door, rocker, pull bar and door body constitutes; Also comprise locking cylinder and latch hook; Described locking cylinder one end and the hinged end of dustbin and latch hook are hinged, the hinged formation of latch hook and the dustbin linkage of locking a door.
The linkage of locking a door that described locking cylinder, latch hook and dustbin constitute is provided with the locking dead point.
Be provided with the linkage of locking a door of symmetry two covers.
The described oil cylinder that opens the door, locking cylinder are connected with hydraulic system through hydraulic sequence valve.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
1, lock a door linkage under the promotion of locking cylinder, the door limit of the locked door of latch hook body makes between the Men Tiyu dustbin seamless; Prevent that mud mixture drippage road pavement from causing secondary pollution; Keep the clean and tidy of environment, adopted hydraulic system, compact conformation, reduced fault rate;
2, lock a door connecting rod be provided with locking the dead point; After locking cylinder is shifted latch hook onto appropriate location; Oil cylinder need not continue fuel feeding, and latch hook still can be locked a body, can not cause because of hydraulic slip having the slit between the Men Tiyu dustbin; Reduce the working time of hydraulic system, protected hydraulic system;
3, symmetry two is set and overlaps the linkage of locking a door, make the stressed symmetry of a body, prevent to have the slit between the Men Tiyu dustbin;
4, open the door oil cylinder, locking cylinder is connected with hydraulic system through hydraulic sequence valve, controls the order open and close of open the door linkage, the linkage of locking a door automatically, easy to operate simply, prevent interference.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, technical scheme of the present invention is elaborated, but protection scope of the present invention is not limited to said embodiment.
As shown in Figure 1, a kind of cleaning sweeper suction garbage can door locking device, the linkage that opens the door that comprise dustbin 7, the oil cylinder 1 that opens the door, rocker 2, pull bar 3 and door body 4 constitutes; Rocker 2 is hinged with dustbin; Realize supporting, the pull bar 3 that is arranged on the body 4 is hinged with rocker 2 respectively with the oil cylinder 1 that opens the door that is hinged on the dustbin, also comprises locking cylinder 5 and latch hook 6; Described locking cylinder one end and the hinged end of dustbin and latch hook are hinged, the hinged formation of latch hook and the dustbin linkage of locking a door.Described locking cylinder 5, latch hook 6 are provided with the locking dead point with the linkage of locking a door that dustbin 7 constitutes, and the described oil cylinder that opens the door, locking cylinder are connected with hydraulic system through hydraulic sequence valve, and the described linkage of locking a door is provided with two symmetrical covers.
When beating opening door body, under the effect of hydraulic sequence valve, at first locking cylinder is opened latch hook, the cylinder action that opens the door then pulling rocker, and rocker drives the pull bar motion, and the door body is followed and is opened; When closing body, under the effect of sequence valve, the oil cylinder that opens the door by the opposite direction fuel feeding after, drive rocker, pull bar cuts out the door body, locking cylinder promotes latch hook with the locked door of latch hook body edge then, realizes that the door body is locked.
