Abstract

The utility model discloses a locking device for a rear tail cover of a harvester, comprising a fixed base, a handle, and a handle support base, the rear side of the fixed base is fixed on a harvester body, the front side of the fixed base extends a fixed base extending edge to one side of the rear tail cover of the harvester, the fixed base extending edge is provided with a U-shaped recess. the handle support base is fixed on an inner side surface of the rear tail cover of the harvester, one end of the handle successively passes through the rear tail cover of the harvester and the handle support base, and is movably connected with the handle support base. When the rear tail cover of the harvester is locked, an inner side surface of the handle body is abutted against the fixed base extending edge, the central part of the handle is clamped in the U-shaped recess on the fixed base. The locking device for a rear tail cover of a harvester is advantaged by simple structure, reliable locking, easy operation, and low cost.

Description

Hood locking device behind the grain header

Technical field

The utility model relates to hood behind a kind of grain header, and the locking device of hood behind especially a kind of grain header belongs to agricultural machinery accessory technical field.

Background technology

Hood is the important component part of grain header behind the grain header, and what its quality quality directly had influence on grain header cleans, sheds performance, and the extended body knapsack of hood upside and grain header body rear side is hinged by hinge behind the grain header.As shown in Figure 1, behind the existing grain header locking device of hood 5 comprise the holder 1 that is fixed on body knapsack 6 one sides, by swivel pin 10 and holder 1 hinged movable grab 2, extension spring 3, be fixed on the lock pin 4 on the hood 5 behind the grain header, extension spring 3 one end hooks hang on the grab 2, and the other end is hooked on body knapsack 6 one sides.When opening behind the grain header hood, upwards lift movable grab 2, extension spring 3 stressed stretchings, movable grab 2 rotates counterclockwise around swivel pin 10 centers, and the gib head 21 of movable grab 2 is thrown off lock pins 4, at this moment can open hood 5 behind the grain header.When closing behind the grain header hood 5, repeat above-mentioned action, when hood 5 puts in place behind grain header, unclamp movable grab 2, under extension spring 3 restoring force effects, the gib head 21 of movable grab 2 clockwise rotates around swivel pin 10 centers, and the gib head 21 of movable grab 2 hooks lock pin 4 locking back hoods 5.Above-mentioned back hood locking device structure complexity, complex operation, service time, because extension spring 3 elasticity diminish, the gib head 21 of movable grab 2 broke away from lock pin 4 easily after long afterwards, and it is unreliable to cause locking.

Summary of the invention

The purpose of this utility model provides hood locking device behind a kind of grain header of simple in structure, easy to operate, reliable lock.

The utility model is achieved by the following technical programs:

Hood locking device behind a kind of grain header, comprise holder, handle, handle supporting seat, described holder rear side is fixed on the grain header body, and holder front side hood one side behind grain header is extended the holder extension edge, and described holder extension edge is provided with the U-shaped recess; Described handle supporting seat is positioned at the holder opposite, is fixed on behind the grain header on the hood medial surface; Described handle comprises fixedly connected handlebody, handle, and described handle one end passes hood behind the grain header, handle supporting seat successively, and flexibly connects with described handle supporting seat; When hood was locked behind the grain header, described handlebody medial surface was resisted against on the holder extension edge, was connected in the middle part of the handle in the U-shaped recess on the holder.

The purpose of this utility model can also further realize by following technical measures.

Hood locking device behind the aforesaid grain header, wherein said handle supporting seat are the trough plate that is fixed in the hood side, back; Be fixed with nut on the described handle supporting seat, handle is screwed on the nut.

The utility model is simple in structure, number of spare parts is few, after the back hood falls the locking grain header during hood, the handlebar stem middle part is sticked in the U-shaped recess on the holder, screws handle then, hood behind the grain header can be locked on the body.Reliable lock, easy and simple to handle, low cost of manufacture.

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.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 2～shown in Figure 4, the utility model comprises holder 1, handle 7, handle supporting seat 8, holder 1 rear side is fixed on the body knapsack 6 by securing member, and holder 1 front side hood 5 one sides behind grain header are extended holder extension edge 11, and holder extension edge 11 is provided with U-shaped recess 12.Handle 7 comprises fixedly connected handlebody 71, handle 72, and handle supporting seat 8 is positioned at holder 1 opposite, is fixed on behind the grain header on hood 5 medial surfaces.Handle supporting seat 8 is the trough plate structure, and the biside plate of trough plate bottom is welded on behind the grain header on hood 5 medial surfaces, is welded with nut 9 in the top board of trough plate.Handle 72 1 ends are screwed on the nut 9 after passing hood 5 behind the grain header, handle supporting seat 8 successively.Behind the locking grain header during hood 5, first turn handle 7 makes behind the inboard and grain header of handlebody 71 between hood 5 sides gap greater than the thickness of holder 1.After hood behind the grain header 5 falls, promote hood 5 behind the grain header gently downwards, handle 72 middle parts are sticked in the U-shaped recess 12 on the holder 1, then handle 7 is screwed, hood behind the grain header 5 is locked on the body knapsack 6.Handle 72 middle parts are connected in the U-shaped recess on the holder 1, screw handle 7, and handlebody 71 medial surfaces are resisted against on the holder extension edge 11, thus hood 5 behind the locking grain header.

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 drop in the protection domain of the utility model requirement.
