Abstract
The utility model discloses a locking device of a grain discharging screw conveyor of a harvester. The locking device comprises a fixed seat, a movable clamping hook, a tension spring and a lock pin, wherein the back side of the fixed seat is fixedly connected with a harvester body of the harvester; the front side of the fixed seat extends towards the outer side of the harvester body to form a fixed seat extending side; a U-shaped notch is formed on the fixed seat extending side; the middle part of the movable clamping hook is hinged with the fixed seat; one end of the tension spring is hooked and hung on the lower side of the harvester body, and the other end of the tension spring is hooked and hung at the upper end of the movable clamping hook; the lock pin is arranged on the grain discharging screw conveyor; the position of the lock pin corresponds to the position of the U-shaped notch on the fixed seat; and when the grain discharging screw conveyor of the harvester is locked, the lock pin is connected into the U-shaped notch on the fixed seat in a clamping manner, and a hook head at the lower end of the movable clamping hook is hooked to the upper end of the lock pin. The locking device has the advantages of simple structure, reliable locking and high work efficiency, and is convenient to operate.
Description
Technical field
The utility model relates to a kind of grain header unloading screw conveyor, and especially a kind of locking device of grain header unloading screw conveyor belongs to agricultural machinery accessory technical field.
Background technology
The silo that the grain header unloading screw conveyor the is installed in grain header mouth of putting out cereal when grain header is in the harvesting state, is packed up unloading screw conveyor and be locked on the body, after silo is filled, opens the unloading screw conveyor unloading.The locking device of existing grain header unloading screw conveyor is the annular anchor ear of being made up of two semi-rings, two semi-ring one ends are hinged by hinge, the other end also lumps together, merging end locks by bolt and nut, annular anchor ear is fixed on the grain header body, during locking grain header unloading screw conveyor, unclamp bolt, open anchor ear, unloading screw conveyor is rotated in place, embrace unloading screw conveyor with anchor ear then, bolt is screwed, thereby unloading screw conveyor is locked on the body, when needing unloading, unclamp bolt, open anchor ear, unloading screw conveyor can be taken out and carry out unloading.Above-mentioned unloading screw conveyor locking device complex operation, inefficiency.
Summary of the invention
The purpose of this utility model provides the grain header unloading screw conveyor locking device of a kind of simple in structure, reliable lock, easy to operate, high efficiency.
The utility model is achieved by the following technical programs:
A kind of grain header unloading screw conveyor locking device, comprise holder, movable grab, extension spring, lock pin, described holder rear side is fixed on the grain header body, the holder extension edge is extended to the body outside in the holder front side, described holder extension edge is provided with the U-shaped recess, described movable grab middle part is hinged with holder, described extension spring one end hook hangs over the body downside, the extension spring other end is hooked on described movable grab upper end, described lock pin is arranged on the grain header unloading screw conveyor, the lock pin position is corresponding with U-shaped recess position on the holder, during locking grain header unloading screw conveyor, described lock pin is connected in the U-shaped recess on the holder, and the gib head of described movable grab lower end catches on the lock pin upper end.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid grain header unloading screw conveyor locking device, wherein said holder are T shape structure.
The utility model is simple in structure, easy to operate, during locking grain header unloading screw conveyor, upwards lift movable grab, the stressed stretching of extension spring, the gib head of movable grab leaves holder U-shaped recess, then unloading screw conveyor is turned to lock pin and snap in position in the holder U-shaped recess, unclamp movable grab this moment, under the effect of extension spring restoring force, the gib head of movable grab catches on lock pin, thus the locking unloading screw conveyor; When needing unloading, repeat above-mentioned action, make the gib head of movable grab throw off lock pin, unloading screw conveyor can be taken out unloading; The utility model reliable lock, high efficiency.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a locking state schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises holder 1, movable grab 2, extension spring 3, lock pin 4; Holder 1 rear side is fixedlyed connected with grain header body 5 by securing member, and the holder extension edge is extended to body 5 outsides in holder 1 front side, and the holder extension edge is provided with U-shaped recess 11, and holder 1 integral body is T shape structure; Movable grab 2 middle parts are hinged by bearing pin 6 and holder 1, and extension spring 3 one end hooks hang over body 5 downsides, the other end be hooked on movable grab 2 on, lock pin 4 is welded on the unloading screw conveyor 7, the position of U-shaped recess 11 is corresponding on the position of lock pin 4 and the holder 1.
During locking grain header unloading screw conveyor 7, upwards lift movable grab 2, extension spring 3 stressed stretchings, movable grab 2 rotates counterclockwise around the center of bearing pin 6, the gib head of movable grab 2 leaves the U-shaped recess 11 of holder 1, then unloading screw conveyor 7 is clockwise rotated, lock pin 4 is snapped in the U-shaped recess 11 of holder 1, unclamp movable grab 2 this moment, under extension spring 3 restoring force effects, movable grab 2 clockwise rotates around the center of bearing pin 6, and the gib head 21 of movable grab 2 catches on lock pin 4, thereby with unloading screw conveyor 7 lockings; When needing unloading, repeat above-mentioned action, make the gib head 21 of movable grab 2 throw off lock pin 4, unloading screw conveyor 7 can be taken out unloading.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drops on the protection of the utility model requirement.
