Abstract

The utility model discloses a back back knotter, include: the reel, fix sieve on the reel, be provided with a plurality of louver sieve piece on the sieve regularly, the louver sieve piece with the angle that the sieve became is 15~30, the three limit of louver sieve piece all with the sieve is moulded plastics as an organic wholely, the louver sieve piece with form the fish scale sieve mesh between the sieve, the fish scale sieve mesh is rectangle fish scale sieve mesh. The utility model discloses a with the louver sieve piece fix on the sieve, to mould plastics as an organic whole, fish scale sieve mesh be rectangle fish scale sieve mesh for trilateral and the sieve of louver sieve piece for back back knotter can prevent that the straw from blockking up, reduces " race grain " loss.

Description

Rear tail sheet

Technical field

The utility model relates to grain header field, particularly relates to a kind of rear tail sheet.

Background technology

Grain header refers to and disposablely can complete harvesting, threshing, and grain is focused on repository, then by conveyer belt grain is being transported to the plant equipment on transport vehicle, it is compared to traditional hand harvest's mode, harvesting function gathers in the crops such as paddy rice, beans, barley and wheat fast in nonirrigated farmland, paddy field, without the need to hunch during harvesting, harvesting efficiency is high.But grain header, when gathering in paddy, all there will be " race grain " phenomenon in various degree, causes foodstuff waste.

Usually four kinds of methods are adopted to be used for solving " race grain " problem, 1 in prior art) pace of adjustment grain header and feed quantity; 2) rotary speed of rice pulling wheel is controlled well; 3) Reasonable adjustment cylinder-concave clearance; 4) adjustable rear tail sheet is adopted.Problem that although said method alleviates to a certain extent " race grain ", " race grain " loss is still very serious.

Utility model content

In view of this, the utility model proposes a kind of after tail sheet, this rear tail sheet solves current grain header " race grain " problem in various degree when gathering in paddy.

The technical solution of the utility model is achieved in that

Tail sheet after a kind of, comprising:

Screen frame;

Be fixed on the sieve plate on described screen frame;

Described sieve plate is provided with regularly several fish scale sieves, described fish scale sieve and described sieve plate angulation are 15 ° ~ 30 °; Three limits of described fish scale sieve are all injected into one with described sieve plate, form fish scale sieve aperture between described fish scale sieve and described sieve plate; Described fish scale sieve aperture is rectangle fish scale sieve aperture.

Preferably, the described sieve of described fish scale sieve rear end is provided with manhole, the diameter of described manhole is 3 ~ 6mm.

Preferably, the length of described rectangle fish scale sieve aperture and described fish scale sieve (3) is 1 ~ 2cm, and the height of described rectangle fish scale sieve aperture is 0.5 ~ 1.5cm.

As can be seen from technique scheme, the utility model by lip(ped) sieve sheet is fixed on sieve plate regularly, three limits and the sieve plate of fish scale sieve be injected into integrally, fish scale sieve aperture is rectangle fish scale sieve aperture, make rear tail sheet to prevent straw blockage, reduce " race grain " loss.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is the structural principle left view of Fig. 1;

Fig. 3 is the structural principle vertical view of Fig. 1.

In figure:

1, screen frame; 2, sieve plate; 3, fish scale sieve; 4, manhole; 5, fish scale sieve aperture.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, Figure 2 and Figure 3, the rear tail sheet that the utility model provides, comprising: screen frame 1; Be fixed on the sieve plate 2 on described screen frame 1; Described sieve plate 2 is provided with regularly several fish scale sieves 3, described fish scale sieve 3 is 15 ° ~ 30 ° with described sieve plate 2 angulation; Three limits of described fish scale sieve 3 are all injected into one with described sieve plate 2, form fish scale sieve aperture 5 between described fish scale sieve 3 and described sieve plate 2; Described fish scale sieve aperture 5 is rectangle fish scale sieve aperture.

In technique scheme, screen frame 1, for fixing, supporting screening plate 2, is avoided when separating objects, because rocking the problem causing sieve plate 2 to be separated from screen frame 1; Sieve plate 2 plays the effect of separation of material, and this sieve plate 2 has that intensity is large, percent opening is high, the function of not easily plug-hole; Between fish scale sieve 3 and sieve plate 2, there is certain aperture, being arranged so that rear tail sheet plays and preventing straw blockage of this aperture, reduce " run grain " effect of losing, when fish scale sieve 3 and sieve plate 2 angulation be 15 ° ~ 30 °, three limits of fish scale sieve 3 are all injected into integrally with sieve plate 2, when formed fish scale sieve aperture 5 is rectangle fish scale sieve aperture 5 between fish scale sieve 3 and sieve plate 2, prevent straw blockage, effect that reduction " race grain " is lost is best.

It should be noted that, in order to reduce " race grain " loss further, the described sieve of described fish scale sieve 3 rear end is provided with manhole 4, and the diameter of manhole 4 is 3 ~ 6mm.

It should be noted that, in order to avoid causing " race grain " problem that problem is serious because of straw blockage sieve aperture, the length of rectangle fish scale sieve aperture and described fish scale sieve 3 is 1 ~ 2cm, and the height of rectangle fish scale sieve aperture is 0.5 ~ 1.5cm, can reduce " race grain " loss.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
