Abstract

The utility model discloses a device is loopbacked to back chain harrow formula, include no. I chain of constituteing by a plurality of chain links, no. II chains, no. I chain, no. II chains all mesh mutually with head sprocket, vice sprocket, head sprocket, vice sprocket be the duplex chain wheel, no. I chain, no. II chain inner circle departments be provided with with no. I parallel a plurality of scraper blades of chain axis, the layer board of scraper blade and harvester on the end clearance cooperation. The utility model discloses a scraper blade of the rotation impurity on with the layer board strikes off to filter impurity through the screen cloth device, have that the face of cover is wide, occupation space is little, among a transportation process characteristics such as less, easy maintenance of loss and low in production cost, reduced the dirt percentage of harvester seed grain, the utility model discloses the suitability is strong, the operation of being convenient for.

Description

Rear chain-and-harrow type loop back device

Technical field

The utility model belongs to a kind of adjusting device of grain header, is specifically related to rear chain-and-harrow type loop back device.

Background technology

Grain header is the machinery of integration harvesting crops.Disposablely complete harvesting, threshing, and grain is focused on repository, then by conveyer belt, grain is being transported on transport vehicle.Also can use hand harvest, the straw of the crops such as paddy and wheat is laid in field, and then carry out picking up threshing with cereal harvesting machinery.The crop harvesting machine of the cereal seeds such as results paddy and wheat and stalk.Comprise grain header, swather, mow binder, grain combine and grain separator etc.Cereal harvesting machinery grows up on the basis of various harvesting, threshing instrument.

Grain header can be divided into side hanging grain header, Backpack type harvester, walking type reaping machine, Horizontal type reaping machine, vertical type harvester according to structure function.

But current grain header also also exists in all many-sides such as use procedure, interior, function patterns the various problems needing solution badly.

Summary of the invention

The utility model proposes for solving prior art Problems existing, its objective is and provides rear chain-and-harrow type loop back device.

The technical solution of the utility model is: rear chain-and-harrow type loop back device, comprise No. I chain be made up of multiple chain link, No. II chain, No. I described chain, No. II chain are all meshed with head sprocket, auxiliary chain wheel, described head sprocket, auxiliary chain wheel are duplex chain wheel, No. I described chain, No. II chain inner ring place are provided with the multiple scraper plates with No. I chain shaft line parallel, the supporting plate upper surface matched in clearance of described scraper plate and grain header.

The connected mode of described No. I chain, No. II chain and scraper plate for welding, rivet.

The supporting plate upper surface gap value of described scraper plate and grain header is less than the particle diameter of cereal.

Described multiple scraper plates are equally spaced is arranged on No. I chain, No. II chain inner ring place.

Screen device is provided with below described supporting plate.

Impurity on supporting plate is struck off by helicoid scraper plate by the utility model, and by screen device, impurity is screened, there is broad covered area, lose the features such as less, easy to maintenance and production cost is low in little, the course of conveying of taking up room, reduce the percentage of impurity of grain header seed, the utility model applicability is strong, convenient operation.

Accompanying drawing explanation

Fig. 1 is front view of the present utility model;

Fig. 2 is vertical view of the present utility model;

Wherein:

1 No. I chain 2 head sprockets

3 auxiliary chain wheel 4 scraper plates

5 No. 6 II, supporting plate chains.

Embodiment

Below, with reference to drawings and Examples, the utility model is described in detail:

As shown in Figure 1, 2, rear chain-and-harrow type loop back device, comprise No. I chain 1, No. II chain 6 be made up of multiple chain link, No. I described chain 1, No. II chain 6 is all meshed with head sprocket 2, auxiliary chain wheel 3, described head sprocket 2, auxiliary chain wheel 3 are duplex chain wheel, No. I described chain 1, No. II chain 6 inner ring place is provided with the multiple scraper plates 4 with No. I chain 1 axis being parallel, described scraper plate 4 and the supporting plate 5 upper surface matched in clearance of grain header.

No. I chain 1, No. II chain 6 rotates under the drive of head sprocket 2, auxiliary chain wheel 3, and the impurity on supporting plate 5, along with No. I chain 1, No. II chain 6 synchronizing moving, when scraper plate 4 moves to above supporting plate 5, can strike off by multiple scraper plate 4.

Scraper plate 4 length in the utility model is greater than the width of supporting plate 5.

The connected mode of described No. I chain 1, No. II chain 6 and scraper plate 4 is for welding, riveting or bolt is connected.

When No. I chain 1, No. II chain 6 is connected for bolt with scraper plate 4, the height of nuts is not higher than scraper plate 4.

Described scraper plate 4 and the supporting plate 5 upper surface gap value of grain header are less than the particle diameter of cereal.The efficiency struck off can be increased, and increase the effect struck off.

Described multiple scraper plates 4 are equally spaced is arranged on No. I chain 1, No. II chain 6 inner ring place.

Screen device (not shown) is provided with below described supporting plate.
