Abstract
The utility model discloses a bin gate structure of a feed bin, which comprises a hatch opening, a gate plate and a driving part of the gate plate, wherein the gate plate is hinged at one side of the hatch opening and matched with the hatch opening, the gate plate and the driving part are connected through a double-rocker mechanism, a first side link in the double-rocker mechanism is fixed on the hinged shaft of the gate plate, and a second side link is connected with the driving part. Compared with the prior art, the utility model has the advantages of flexible motion of the gate plate, reliable closing, no dust overflow, self-locking function and the like, conforms to environmental protection requirements and is suitable for all concrete mixing plants, particularly for urban commercial concrete mixing plants with high environmental protection performance requirements.
Description
Technical field
The utility model belongs to feed bin, is specifically related to a kind of door structure of feed bin.
Background technology
All use band conveyor to carry in the aggregate course of conveying of concrete mixing plant, cause the aggregate time of delivery also longer because of belt feeder is long, general all the setting in the conduct of transition feed bin on puddle mixer top stored up to improve the work efficiency of concrete mixing plant.The door of available coagulation soil mixing station transition feed bin has two kinds of forms in the market.A kind of is the arc door: establish the arc door-plate below Hatch Opening, hang on the semiaxis that is installed in the feed bin side plate at the door-plate two ends, carries out door by the air cylinder driven door-plate and open and close.Because door, arm, cylinder all are in the Hatch Opening outside and all are movable part, Hatch Opening can't seal, and causes a large amount of flour dust overflows in the puddle mixer during work.Another kind is a plate-turning door: door-plate places Hatch Opening inside, door-plate and the welding of door-plate axle, and axle head connects swing arm, drives door-plate axle and the switching of door-plate rotation carrying out door by the swing arm of cylinder direct drive.Because this structure adopts lever principle, it was from an end that weighs on lever when feed bin was filled the sandstone material, cylinder action is in the other end of lever, aging or leak material because sandstone material action of gravity door can be opened to form automatically when losing efficacy when cylinder packing, not enough or will form the miscarrying material when losing pressure and cause industrial accident if air pressure appears in gas path failure.
The utility model content
Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, provides a kind of and closes reliably, and non-flour dust overflow has the door structure of the feed bin of auto-lock function.
The technical scheme that its technical matters that solves the utility model adopts is: the door structure of feed bin comprises Hatch Opening, be hinged on the door-plate that Hatch Opening one side cooperates with Hatch Opening and the drive element of door-plate, be connected by double rocker mechanism between described door-plate and the drive element, first side link in the double rocker mechanism is fixed on the hinge of door-plate, second side link is connected with drive element, is self-locking state when door-plate cuts out.
Described drive element is air cylinder or hydraulic actuating cylinder.
The bottom of described Hatch Opening is provided with flanged (FLGD) tubular connecting portion.
Adopt the door structure of the feed bin of said structure, when driving door-plate by double rocker mechanism, drive element closes when making door-plate be in sealing Hatch Opening position, connecting rod in the double rocker mechanism and second side link shape in line make door-plate become self-locking state not rotate, and have effectively prevented to cause miscarrying material accident owing to other reason is opened door-plate.The connecting portion of Hatch Opening bottom can be connected the purpose that reaches the sealing Hatch Opening with the stirring cover by the flange on it, and door-plate is at osed top space motion, non-flour dust overflow during work.
The utility model has the door-plate motion flexibly compared with the prior art, closes reliably, and non-flour dust overflow has advantages such as auto-lock function, and compliance with environmental protection requirements is fit to the demanding city of all concrete mixing plants, particularly environmental-protecting performance commerical ready-mixed concrete mixing plant.
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Description of drawings
Fig. 1 is a front schematic view of the present utility model
Fig. 2 is a side schematic view of the present utility model
The specific embodiment
See Fig. 1, Fig. 2, the door structure of feed bin comprises Hatch Opening 9, be hinged on the door-plate 7 that cooperates with Hatch Opening 9 on the feed bin base plate 2 of Hatch Opening 9 one sides and the drive element 1 of door-plate 7, drive element 1 is air cylinder or hydraulic actuating cylinder, be connected by double rocker mechanism between door-plate 7 and the drive element 1, double rocker mechanism comprises first side link 6 and second side link 4 that is hinged on the feed bin base plate 2, with first side link 6 and second side link, 4 pivotally attached connecting rods 5, first side link 6 is fixed on the hinge 12 of door-plate 7, second side link 4 is connected with drive element 1 by the connecting arm 10 that is fixed on its hinge 11, the hinge 11 of second side link 4 is installed on the axle bed 3, and the bottom of Hatch Opening 7 is provided with flanged (FLGD) tubular connecting portion 8.
Under the door-plate closed condition:
Door-plate 7 cut out Hatch Opening 9 when drive element 1 promoted 4 rotations of second side link and makes itself and connecting rod 5 in alignment by connecting arm 10, and door-plate 7 is by Hatch Opening 9 mechanical position limitations, and feed bin can be feeded.Door-plate 7 is ordered about in the deadweight of sandstone material reverse trend, cause second side link 4 is in alignment with connecting rod 5, so door plate 7 forms self-locking and can not rotate, and has effectively prevented owing to other reason door plate is opened the miscarrying material accident that causes, shown in 7 solid lines of door-plate among Fig. 1.
When feeding intake:
Leak material because sandstone material action of gravity meeting opens to form automatically when door-plate can or not lose efficacy because of air cylinder (hydraulic actuating cylinder) seal aging, or press not enough or lose the pressure mistiming and feed intake and cause industrial accident because of gas (liquid) appears in gas (liquid) road fault.
Claims (2)
1. the door structure of a feed bin, comprise Hatch Opening, be hinged on the door-plate that Hatch Opening one side cooperates with Hatch Opening and the drive element of door-plate, it is characterized in that being connected by double rocker mechanism between described door-plate and the drive element, first side link in the double rocker mechanism is fixed on the hinge of door-plate, second side link is connected with drive element, is self-locking state when door-plate cuts out.
2. the door structure of feed bin according to claim 1 is characterized in that the bottom of described Hatch Opening is provided with flanged (FLGD) tubular connecting portion.
