Specific embodiment
Below, the present invention is specifically described by exemplary implementation method.It should be appreciated, however, that not entering one
In the case of step narration, element, structure and features in an implementation method can also be advantageously incorporated into other embodiment
In.
In the description of the invention, it is necessary to explanation, " interior ", " outward " of feed mechanism for seed, " on ", D score, "front", "rear"
The orientation or position relationship of instructions such as " top " " bottoms " are, based on the position relationship shown in accompanying drawing 1, to be for only for ease of description
The present invention is described with simplified, must be with specific orientation, with specific rather than the device or element for indicating or imply meaning
Azimuth configuration and operation, therefore be not considered as limiting the invention.
Referring to Fig. 1, Fig. 2, Fig. 4 and Fig. 7, as illustrated, feed mechanism for seed of the invention, for the sowing of a ridge duplicate rows, wraps
Include housing 1, housing 1 is internally provided with rotatable discharge plate 2, discharge plate 2 by the inside longitudinal subdivision of housing 1 formed induction chamber and
Seed chamber, the top of housing 1 is provided with seed inlet, and the bottom of housing 1 is provided with sowing port, and the bottom of sowing port is provided with a point kind
Unit 3, point kind of unit 3 includes point kind of the box 31 just to sowing port, and the upper bottom surface of point kind of box 31 is opening and sets, point kind of box
Fixing axle 33 is crossed inside 31, left and right two chambers have been divided on the basis of point kind of box middle part longitudinal surface inside point kind of box 31, Gu
The axle sleeve 34 that can be rotated around fixing axle 33 is arranged with dead axle 33, being installed with axle sleeve 34 can block any chamber upper end and open
The baffle plate 37 of mouth, is also installed with reversal means 36 on axle sleeve 34, reversal means 36 can be against the lateral surface of discharge plate, and reversal means 36 is in seeding
Baffle plate 37 is promoted to rotate under the drive of disk 2, when baffle plate 37 turns to the chamber for sheltering from one of them, seed is fallen into another
Chamber, so can be achieved with the separation of duplicate rows seed, make sowing more accurate.
Referring to Fig. 3-Fig. 6.As shown in figures 3 to 6, discharge plate 2 includes the multiple disk teeth being distributed on the excircle of discharge plate 2
21, two feed outlets of adsorbable seed 22 are provided with the discharge plate 2 between adjacent disc tooth；The connection of baffle plate 37 and axle sleeve 34
Place is provided with opening, is provided with torsion spring 35 on axle sleeve 34, torsion spring 35 through opening sleeve on axle sleeve 34, reversal means 36 and baffle plate 37
Between it is at an acute angle, the angle Selection of the acute angle depends on the length of reversal means, and when acute angle, the length of reversal means without it is long i.e.
Can meet and drive at flapper to the upper end open of chamber, and in acute angle, the dynamics of the fluctuation disk tooth that reversal means is born is most
It is excellent, herein preferably 30o-60o, effect at an acute angle herein is, when reversal means is against on disk tooth, baffle plate can move in left side or
Right lateral position, and when baffle plate is continued to move to, baffle plate departs from disk tooth, because of the disk tooth in discharge plate bottommost and the upper end open of chamber
Between have certain distance, by reversal means be capable of achieving displacement variation；Under non-driving state, the end of reversal means 36 is against and turns
Move on the disk tooth 21 of bottommost discharge plate, and baffle plate is now in right lateral position or left lateral position, in the present embodiment, at baffle plate
At left chamber, one end of torsion spring 35 is against in reversal means 36, and the other end is against on point kind of the inwall of box 31.
It is the side view of point kind of unit in Fig. 1 referring to Fig. 5.As shown in figure 5, feed mechanism for seed also includes being arranged on point kind of a unit 3

The discharging tube 42 of first 41 bottom.Seeding first 41 is set to easily guide the hollow cone of seeds fall；Two dislocation of discharging tube 42 set
Put, so by adjusting the distance between discharging tube, you can on regulation ridge the interval of two row seeds.
By above structure, in seeding, seed is from seed inlet by the seed chamber into enclosure interior, air-breathing for feed mechanism for seed
Room air-breathing, makes to form pressure difference between induction chamber and seed chamber, and seed is adsorbed to the row of discharge plate from seed chamber under differential pressure action
Plant on hole, and operated to the sowing port of bottom with discharge plate, the reversal means in point kind of unit is against on the disk tooth of discharge plate, discharge plate
Rotate and promote reversal means motion, while baffle plate is moved, torsion spring is compressed, when baffle plate moves to right chamber top, shelter from right side
During chamber, opening state is in seeding unit, seed falls into seeding unit discharge from left chamber；With discharge plate after
Continuous to rotate, disk tooth departs from reversal means, and in the presence of torsion spring, baffle plate is returned to left chamber top, shelters from left chamber, plants
Son falls into seeding unit discharge from right chamber；Alternate cycles realize double row sowing.
In addition, the bottom of discharge plate 2 be provided with seed can be scraped from feed outlet scrape kind of tongue 5, under discharge plate turn
To sowing port, seed can be scraped in the presence of kind of tongue is scraped.
In the present invention, as shown in Fig. 2 the side of discharge plate 2 is provided with the sprocket wheel 6 that discharge plate 2 can be driven to rotate.
In order to point kind of a unit is connected on housing, the outside of point kind of box 31 is symmetrically arranged with the company being connected with housing 1
Fitting 32, connector 32 is bolted on housing with point kind of box, so, when kind of unit need not be divided, can be by tearing open
Unloading bolt will point kind of unit disassembling or replacing.
In addition, present invention also offers a kind of seeder, the bottom of the seeder is provided with above-mentioned feed mechanism for seed.
By feed mechanism for seed of the invention and seeder, seed in point kind of the unit by feed mechanism for seed, broadcast by seed demand
Plant during to ridge upper left side row, baffle plate moves to right lateral position and blocks right chamber mouthful, when thus sowing seed, can realize accurately broadcasting
Kind.
The above, is only presently preferred embodiments of the present invention, is not the limitation for making other forms to the present invention, is appointed
What those skilled in the art changed possibly also with the technology contents of the disclosure above or be modified as equivalent variations etc.
