Description
Technical field
A kind of seeding machinery is the utility model is related to, particularly sows the device of seed.
Background technology
At present, Mechanization sowing to have the advantages that to save seed, sowing accurate is agriculturally being popularized.It is existing to broadcast
Kind machine uses the structure of seed wheel mostly, and seed is fallen into the kind cave on seed wheel by gravity, under kind of the auxiliary of brush, plants in cave
Appropriate seed is included, when kind of a cave is rotated to seeding hole site, now drops out feed outlet by gravity without hairbrush, seed, most
Fall into eventually at sowing, reach sowing purpose.With Various Seasonal or different needs, different seeds is selected to be sowed, by
It is larger in the size difference of different seeds, therefore, it is necessary to which accurate sowing could be realized by changing different seed wheels.But due to
The structure of seeder is limited, and it is not a nothing the matter for most peasants to change seed wheel, is not only wasted time and energy, often
Adjustment is gone wrong frequently less than optimum state, directly increases the labor intensity of peasant, delay farming season.Further, since the knot in kind cave
Structure is that fixed size is constant, when seed size inequality, often occurs having more due amount in a kind cave, not only wastes kind
Son, it can also provide the thinning work increase workload of after seedling.
The content of the invention
The purpose of this utility model is to provide a kind of adaptation seed ranges extensively and can realize group seed device of precision drilling.
The technical solution of the utility model is：A kind of seeder dial seed device, including plants case, rotating disk, fixing axle and dial

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not formed to the utility model
Any restrictions.Shown in Fig. 1, Fig. 2 and Fig. 3, the utility model includes plants case 1, rotating disk 2, fixing axle 5 and toggle mechanism.It is described
One end of fixing axle 5 sequentially passes through the axis hole of rotating disk 2, cam 3 and plants case 1, and the cam 3 is fixed in fixing axle 5, the kind
Case 1 fixes as one with cam 3, the rotating disk 2 and the rotatable engagement of fixing axle 5.Shown in Fig. 4, the toggle mechanism, which is arranged on, to be turned
On disk 2, toggle mechanism includes dialling seed block 21, shell fragment 23 and connecting rod 22, and seed block 21, other end connection bullet are dialled in the connection of the one end of connecting rod 22
Piece 23, shell fragment 23 and group seed block 21 are hinged with connecting rod 22 to be coordinated.Bearing pin 26 is fixed on rotating disk 2, is dialled seed block 21 and is enclosed on bearing pin
It is fixed on 26 and with the rotatable engagement of bearing pin 26, spring catch on rotating disk 2, shell fragment 23 is enclosed on spring catch and matched somebody with somebody with spring catch rotation
Close, spring 25 is set with spring catch, the one end of spring 25 is withstood on limited post 24, and the other end is hooked on shell fragment 23, the limit
Position post 24 is fixed on the outside of shell fragment 23 on rotating disk 2 and between connecting rod 22 and spring catch.After above-mentioned installation, Fig. 1 and
Shown in Fig. 7, the seed inlet 11 of plants case 1 is located directly below, and inner side edge and the gap of rotating disk 2 of plants case 1 coordinate, a left side for the side wall of plants case 1
Top is provided with seed outlet.Shown in Fig. 3 and Fig. 4, the cam 3 is made up of reducing curved surface and interior concane gap, the interior notch on cam 3
Seed outlet described in mouthful face in plants case 1, shell fragment 23 be pressed in by elastic force on cam 3 and with the curved spring cooperation of the reducing of cam 3.
Being caught in toggle mechanism, can be set up between plants case 1 and cam 3 shown in Fig. 3 and Fig. 4, during to prevent that seed from dropping
Inner cover 4, the inner cover 4 are located in plants case 1, and inner cover 4 is fixed on rotating disk 2, and inner cover 4 covers cam 3 and shell fragment 23.
Shown in Fig. 5 and Fig. 6, seed is more effectively clamped to enable to dial seed block 21, the working face for dialling seed block 21 is provided with ditch
Groove, the groove are vertically used to logical form by transverse groove and cannelure.The groove direction of the transverse groove is parallel with rotating disk 2, described
The groove direction of cannelure is vertical with rotating disk 2.Cannelure is positioned at the one end for dialling remote bearing pin 26 on seed block 21.
During work, in frame, Chu Zi mechanisms and land wheel are fixed as one fixing axle 5 with rotating disk 2, before promoting seeder
OK, land wheel rolls forward, so as to drive rotating disk 2 to rotate.Seed is put into from the seed inlet 11 of plants case 1, and seed is dialled with what rotating disk 2 rotated
When block 21 is by 1 lower end of plants case, seed is scraped in the cavity that it forms with plants case 1, with the continuous rotation of rotating disk 2, convex
Under the effect of wheel 3, the angle dialled between seed block 21 and the inwall of plants case 1 diminishes, and cavity originally diminishes, therefore dials seed block 21 and clamp one
After grain seed, because the relation of angle is difficult to reclamp second seed, after rotating disk 2 turns over certain angle, in the work of gravity
Under, do not dialled the seed clamped of seed block 21 it is automatic under drop back into the bottom of plants case 1, gone to when dialling seed block 21 at the seed outlet of plants case 1
When, the shell fragment 23 of toggle mechanism is just slipped into the interior concane gap of cam 3, and now, in the presence of spring 25, energy is released
Put, the momentary reset of shell fragment 23, pulled by connecting rod 22 and dial the seed ejection that seed block 21 clamps group seed block 21, seed is just from kind
The seed outlet ejection of case 1, is finally sown into soil through land wheel, reaches sowing purpose.The structure of land wheel is prior art, its install and
Using to be public, will not be repeated here.Seed is more effectively clamped to enable to dial seed block 21, dials the transverse groove energy of seed block 21
Make seed along groove proper alignment, be easy to essence amount clamping seed, meanwhile, dial seed block to prevent the seed in transverse groove from departing from too early
21, dial the cannelure on seed block 21 and play a part of blocking seed transversely groove landing, after group seed block 21 presss from both sides steady seed, turn
Seed is spontaneously decoupled under gravity in the rotary course of disk 2 and dial seed block 21, prevent the empty phenomenon broadcast.
