Abstract

The utility model relates to a rice seed coating and direct seeding machine which is a seeding machine for coated rice seeds in agricultural production. The utility model has the technical proposal that ditching dragging plates are changed from original one body to a plurality of bodies, and the front edges of the ditching dragging plates of both sides of a machine body are respectively provided with a mud baffle plate 20; seed fall points are moved backwards, which makes seeds fall in seed grooves with stabilized mud and water; the distance of outlets of seed guide grooves 7 and the seed grooves on ground is shortened, and mud baffle covers are additionally arranged on the seed guide grooves. The utility model has the advantage that the phenomena that the seeds are covered by the mud and the water are lightened, when the seeds fall off from the seed guide grooves, the seeds are free from the influence of the mud, the water and the wind, and the seeds can accurately fall into the grooves, which is favorable to the emergence of seedlings.

Description

A kind of coating paddy seeds seed-sowing machine

The utility model relates to sower, a kind of coating paddy seeds seed-sowing machine of definitely saying so.

Seed coating technology is an emerging technology in agricultural production, also there is not good special seeder tool behind the coating paddy seeds at present, utility model patent (patent No.: 94230522.1) preferably resolve the live ask for something of coating paddy seeds as save seed, reduce cost, simple to operate, main be not establish earthing and press kind of a device, the germination and emergence that helps seed, even so, still there are following 3 deficiencies in this machine:

1, because trench layering and seed guiding groove longitudinal separation is too near, so seed still has a small amount of earth to cover in the above after broadcasting kind of ditch, that is to say behind the trench digging that in a short period of time and then sowing has some earth to be slipped in kind of the ditch unavoidably, to plant subcovering, be unfavorable for emerging, finally influence output.

2, because the kind bed of this machine trench digging supporting plate is an integral body, to gather around mud comparatively serious so it gathers around water, the kind subcovering that muddy water can be sowed the last time.

3, former seed guiding groove so usually spatter some muddy water, is adhered to herein seed because of not installing lid additional, the uniformity of influence sowing.For fear of above-mentioned phenomenon, have no alternative but raisings such as seed guiding grooves, influenced the seed accuracy of placement so again, especially even more serious in the wind sky.

The seed that the purpose of this utility model is to provide a kind of trench digging to sow be difficult for by muddy water cover, seed accurate placement, the favourable coating paddy seeds seed-sowing machine of emerging, improve output.

The purpose of this utility model is achieved in that one is to change the trench digging supporting plate into many bodies by original one, and respectively is provided with a fender in the trench digging supporting plate front of body both sides outer rim.The 2nd, move after making kind of point, allow seed fall in the kind ditch of muddy water after stable.The 3rd, the distance of seed guiding groove outlet and ground seed channel shortens, and has installed seed guiding groove additional lid.

Advantage of the present utility model is: the phenomenon that muddy water covers seed alleviates greatly, and seed is not subjected to the influence of muddy water, wind when being fallen by seed guiding groove, can fall into accurately in kind of the ditch, helps emerging and improving output.

Introduce embodiment of the present utility model below in conjunction with accompanying drawing.Be welded into the round steel pipe of diameter one-inch and be wider than long square box 4.Be welded with the traction bars 6 of traction usefulness on the square frame 4, seeding unit 15 and kind cassette carrier 3, trench digging supporting plate 17 and road wheel 5 all will be fixed on the square frame 4, planting a bed trench digging supporting plate 17 is slab constructions, can determine the quantity of supporting plate 17 according to the quantity of seeding unit 15, the quantity of supporting plate of promptly ditching is corresponding with the quantity of seeding unit, the front of supporting plate 17 is upturned, available bolt and nut is fixed on the square frame 4, the outer rim at the place of being upturned, supporting plate the place ahead, the whole sower left and right sides is respectively established a fender 20, the back of supporting plate, between supporting plate 17 and square frame 4, be provided with a riser 8, in order to fixing and limit between supporting plate and the square frame distance, the back of supporting plate 17 and riser 8 is provided with empennage 9, and its effect is to help crossing field stalk, is provided with two kind bed trench layerings 2 below each piece supporting plate back.

The seeding part is planted case 1 by seeding unit 15, and seed guiding groove 7 is planted cassette carrier 3 and constituted.Seeding unit 15 can be selected the general outer groove wheel seeding units of sower such as wheat for use, is installed in kind of a case bottom and is having on the corresponding position of square hole, and seed guiding groove 7 has added mud retaining cover 13 on the prior art basis, and whole seed guiding groove is a trapezoidal square tube shape structure.Its top one side is provided with sowing tongue 10 lower middle position and is provided with branch kind fork 11, its the higher authorities are provided with a tubular structure 12, with pin be fixed on seeding unit 15 sowing port following, the effect of seed guiding groove 7 is that the seed that seeding unit is discharged is divided into two strands by a minute kind fork 11, the effect of sowing tongue 10 is by changing its angle, guarantee to aim at the tip on branch kind of fork 11 tops owing to the kind stream center that the adjustment amount of broadcasting changes, make two strands of kind streams evenly, the back of square frame 4 is provided with kind of cassette carrier 3, plants case 11 and is fixed on kind of the cassette carrier 3 by support 14.

The seeding drive part produces power by engine and drives seeding unit axle 18 by power transmission shaft 19, worm and gear 16, and the rotation of seeding unit axle 18 promptly begins seeding.

Traction element is assigned to finish by the tractive unit of " link-type petrol engine driven rice sprout transplanter ", as shown in Figure 1.
