Description
Technical field
The present invention relates to seeders.
Background technique
Wheat is stooling crop, and under reasonable cultivation condition, the tiller of wheat can form yield, wheat point at fringe
Tiller number improves, and can increase secondary root to stem, wheat is made to absorb more nutrients during the growth process.Want to improve wheat
Tiller, it is necessary to which " the even strain of indention " gives the enough growing spaces of every wheat, existing outer groove-wheel strip sowing seed discharge device, due to this
There are pulsating natures for seeding in low speed operation for two kinds of seeding methods, so that seeding uniformity, stability are affected, however high speed
The breakage rate of seed can increase therewith again when operation, be difficult to realize the purpose of uniform wheat sowing, have when due to work by sheave
It imitates working area and dials lower wheat seeds progress operation, so that its operation line-spacing >=15 ㎝, because after 15 ㎝ of <, sheave effective operation area
Become smaller, job insecurity, and pulsating nature increases, uneven sowing is even, and it is extensive to there is sowing.Uneven sowing is even, and wheat seeds waste is serious
The shortcomings that.Therefore want sowing 15 ㎝ of <, it is also necessary to which more accurate wheat feed mechanism for seed is realized.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of duplicate rows can be achieved the list of wheat from feed mechanism for seed, the present invention is stirred
Grain sowing, belongs to Precision Seeding scope, and, for promoting wheat tillering, improving wheat yield has obvious action for this.
In order to solve the above technical problems, the technical solution used in the present invention is:
A kind of duplicate rows stirring wheat feed mechanism for seed, including kind of box certainly, it is identical to be symmetrical set two shape and structures in kind of box
Left side feed mechanism for seed and right side feed mechanism for seed, feed mechanism for seed include a seed wheel, hairbrush, two seed cleaning sheets and a discharging tube, seeding
The outer rim of wheel is equipped with such as flowering structure: flange is circumferentially in the middle part of ring seed wheel outer rim, the cross sectional shape of flange is intermediate high by two
Side is low, is provided at circumferentially spaced indent in the outer rim of two side ring seed wheel of flange, the indent of flange two sides is alternately arranged, in indent
Portion is equipped with seed cleaning sheet and is adapted to gap, and it is annular gap that seed cleaning sheet, which is adapted to gap, and bottom is the circular base concentric with seed wheel；
In in kind of box, seed wheel lower half kind cassette bottom portion, hairbrush is fixed on the kind box positioned at the front end of seed wheel for seed wheel upper portion
Bottom, for stopping seed to fall, a formation kind box front bottom end, the brush filament of hairbrush and the front outer of seed wheel are in close contact,
It is fixed close to the bottom of front end with two seed cleaning sheet one end in kind of box, two seed cleaning sheet other ends are inserted into two seed cleaning sheets respectively
