The multifunctional adjusting sieve of the harvester has simple structure and reasonable design, is provided with a blast orifice, can completely separate straws from seeds, and avoids grain leakage, in addition, the angle of the rear sieve is adjustable, the bent part of the rear sieve is short, more rear sieves can be distributed, and the multifunctional adjusting sieve is adaptive to different harvesting speeds and is suitable for various models of harvesters.

Description

The multi-functional adjustment sieve of grain header

Technical field

The utility model belongs to field of agricultural machinery, relates in particular to a kind of multi-functional adjustment sieve of grain header that is used to screen grain.

Background technology

At present, when crops are ripe, can significantly enhance productivity with the grain header harvesting.Grain header is the collection harvesting, and the threshing function is the machine of one, is cutting down on the basis of cereal, and it can separate crops straw with seed, and collects and take care of oneself.Sieve is the important component part of grain header, and its effect is that seed is separated with stalk, on traditional sieve; The slot size design is unreasonable; Do not have the air port on its original sieve, can't guarantee that not only stalk is all blown away and screens out, and when the seed that falls is too much, sieve aperture can occur blocking; Cereal falls into phenomenons such as external container, causes economic loss.

Summary of the invention

The purpose of the utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, can stalk be separated with seed fully, does not leak grain, is suitable for the multi-functional adjustment sieve of grain header that on multiple model grain header, uses.

In order to achieve the above object, the technical scheme that the utility model adopts is: comprise back sieve, back sieve angle adjustment lever, fore worker, vertical pole, fore worker is fixed on the bottom of pedestal; Be distributed with a plurality of sieve apertures on it, be fixed with a stalk scraping teeth between every row's sieve aperture, the both sides of back sieve angle adjustment lever are connected with the back sieve; Sieve middle part, back is affixed with control stick; Back sieve angle adjustment lever two ends are connected with through hole on the vertical pole, and vertical pole and cross bar are fixed on the pedestal, and the control stick adjuster is fixed in pedestal top.

The utility model has the advantages that:

1, simple in structure, reasonable in design, this device is provided with blast orifice, can stalk be separated with seed fully, does not leak grain;

The bending part of 2, back sieve adjustable angle, and back sieve is short, sieves behind the greater number of arranging, and adapts to different harvesting speed, is suitable on the grain header of multiple model, using.

Embodiment

Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.

Can be known that by Fig. 1-Fig. 7 the utility model comprises back sieve 2, back sieve angle adjustment lever 3, fore worker 4, vertical pole 7, fore worker 4 is fixed on the bottom of pedestal 8; Be distributed with a plurality of sieve apertures on it, be fixed with a stalk scraping teeth 5 between every row's sieve aperture, the both sides of back sieve angle adjustment lever 3 are connected with back sieve 2; Sieve 2 middle parts, back and control stick 1 are affixed; Back sieve angle adjustment lever 3 two ends are connected with through hole on the vertical pole 7, and vertical pole 7 and cross bar 9 are fixed on the pedestal 8, and control stick adjuster 10 is fixed in pedestal 8 tops.

Sieve 2 bottoms, described back are distributed with a plurality of blast orifices 6, and its bottom is bent.

Described control stick adjuster 10 is provided with arc chute, and right angle handle 11 is tightened on the arc chute through bolt, and its left lower end is connected with control stick 1.

Described vertical pole 7 is provided with a plurality of through holes.

Described orbital canal,anterior internal 12 is shaped as elliptical aperture.

The utility model is the harvesting soya bean, and with fore worker 4, both sides were parallel about the shape of orbital canal,anterior internal 12 became during harvesting corn during granule cereal such as paddy rice, and the left and right sides is radian.According to the difference of harvesting crops, fore worker 4 can only be installed on the pedestal 8 of the utility model or back sieve 2 only is installed.During use pedestal 8 is installed on the grain header, fore worker 4 is fixed in pedestal 8 bottoms, and the bending place that back sieve angle adjustment lever 3 is welded on back sieve 2 is installed on the pedestal 8 afterwards, and this moment, fan blower was arranged at the bottom of pedestal 8.After the start, matrix 8 is with reciprocating, and the seed of impurity such as the stalk that mixing at first drops on the fore worker 4, and seed is heavier, falls in the sieve aperture of fore worker 4, and stalk is lighter, and some wind of being derived by sieve aperture blows away, and some stalk scraping teeth of being shaken is drained.Back sieve 2 plays booster action, anti-leak-stopping grain.According to the different sizes of harvesting seed, its elevation angle is adjustable.When control stick 1 moved forward, the elevation angle of back sieve 2 became big, and it is big that its spacing becomes, and when control stick 1 moved backward, the elevation angle diminished, the pitch smaller of back sieve 2.When seed that falls when the some time and stalk were too much, some seed and stalk can fall into sieve 2 tops, back, and this moment, seed fell from the gap of back sieve 2, and stalk is blown away to the wind that goes out by blast orifice 6.
