For further setting forth that the present invention reaches technological means and effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to the detailed description of the invention of the present patent application, structure, feature and effect thereof, describe in detail as after. In the following description, what different " embodiments " or " embodiment " referred to is not necessarily same embodiment. Additionally, special characteristic in one or more embodiment, structure or feature can be combined by any suitable form.

As it is shown in figure 1, a kind of seeder that one embodiment of the present of invention proposes, including frame 1, ditcher mechanism 3, fertilizing mechanism 4, shaping wheel 5, elevating mechanism 6, duck-beak type seeder 7, casing mechanism 8 and press wheel 9.

As it is shown on figure 3, the upper front end of frame 1 is provided with hanger bracket 2, this hanger bracket 2 includes the first hanger bar the 21, second hanger bar 22 and the 3rd hanger bar 23. First hanger bar the 21, second hanger bar 22 and the 3rd hanger bar 23 three parallel interval successively are arranged. Second hanger bar 22 is placed between the first hanger bar 21 and the 3rd hanger bar 23, and the first hanger bar 21 second hanger bar 22 relative to both the 3rd hanger bar 23 is arranged symmetrically with. One end of first hanger bar 21, one end of the second hanger bar 22 and one end of the 3rd hanger bar 23 are all connected with the upper front end of frame 1, the other end of the first hanger bar 21, the other end of the second hanger bar 22 and the other end of the 3rd hanger bar 23 are free end, and the front end of all relative frame 1 forward extends out. One end that first hanger bar the 21, second hanger bar 22 and the 3rd hanger bar 23 three relative frame 1 front end are stretched out is equipped with hook 201. Hanger bracket 2 is suitable with the connecting portion on outside walking arrangement such as tractor, the connecting portion of tractor includes the hanging hole suitable with hook 201, the quantity of hanging hole is consistent with the quantity of hook 201, hook 201 in first hanger bar the 21, second hanger bar 22 and the 3rd hanger bar 23 hangs in the hanging hole on tractor respectively, so that tractor can be walked by tractor seeder between field. In the present embodiment, first hanger bracket the 2, second hanger bracket 2 and the 3rd hanger bracket 2 three constitute trifilar suspension system, hang relative to single-point, and the stability of the trifilar suspension in the present embodiment is preferably.

In an alternative embodiment, aforesaid hanger bracket 2 can also only include single hanger bar, and this single hanger bar is placed in the front center of frame 1, and seeder of the present invention is connected by the connecting portion of this single hanger bar with outside walking arrangement.

As it is shown in figure 1, ditcher mechanism 3 includes first connecting rod 31 and trench digging part 32. The upper end of first connecting rod 31 is connected with frame 1. As in figure 2 it is shown, trench digging part 32 includes upper side edge 321, front side edge 322, lower side 323 and the back side edge 324 that head and the tail connect successively. Lower side 323 is horizontally disposed with, and the angle α between front side edge 322 and lower side 323 is 45 degree, so that front side edge 322 opposite lower limit 323 tilts backwards, and the resistance in front side edge 322 during to reduce grooving. Side, front side edge 322 place opposite posterior limit 324 place lateral bend is also opening the arc groove 325 forming through upper and lower two ends on component. Front side edge 322 has the edge of a knife 3221, and one end opposing with arc groove 325 of trench digging part 32 is connected with the lower end of first connecting rod 31, and ditcher mechanism 3 offers groove by part 32 of ditching on soil to be sowed. In the present embodiment, front side edge 322 opposite lower limit 323 tilts backwards, and in the process that seeder of the present invention is advanced, front side edge 322 can be passed through the edge of a knife 3221 thereon and isolate soil to excavate groove. The soil that front side edge 322 is dug out by the edge of a knife 3221 can derive the side to groove along the upper end open of arc groove 325.

In an alternative embodiment, angle α between above-mentioned front side edge 322 and lower side 323 can also be other numerical value between 30 degree, 60 degree and 30 degree～60 degree, so can also reach the sweptback technique effect in front side edge 322 opposite lower limit 323, to reduce the resistance during edge of a knife 3221 grooving in front side edge 322.

Further, aforesaid lower side 323 also having the edge of a knife, the edge of a knife on lower side 323 cooperates with the edge of a knife 3221 in front side edge 322, and soil isolates and excavates groove jointly, and band is improved the technique effect of trench groove efficiency.

When outside walking arrangement tractor seeder advances, first traction wheel 11 rotates, the first drive sprocket 131 on first traction wheel 11 is along with rotating together, first drive sprocket 131 drives the first driven sprocket 132 to rotate, first driven sprocket 132 drives fertilizer gear 12 to rotate, fertilizer in fertilizing box 41 is derived in the process that fertilizer gear 12 rotates the upper end open to the pipe 42 that applies fertilizer, and fertilizer drops in groove in the effect of self gravitation then through by fertilising pipe 42. In the present embodiment, the fertilizer in fertilizing box 41 can be broken up when fertilizer gear 12 rotates, to prevent blocking fertilising pipe 42.

Further, as it is shown in figure 9, seeder of the present invention also includes body feed tank 52. Body feed tank 52 is arranged in frame 1. Body feed tank 52 is connected with the charging aperture of duck-beak type seeder 7 by seed spout 57, to carry seed in duck-beak type seeder 7 at any time by body feed tank 52.

For preventing the bonding caking of seed, blocking seed spout 57, the embodiment of the present invention also provides for following embodiment: as it is shown in figure 9, aforesaid seeder also includes the second traction wheel 53, seeding gear 54 and the second drive mechanism 55. Second traction wheel 53 is rotatably arranged in below the front end of frame 1 by rotating shaft. Seeder of the present invention is walked on the ground by this second traction wheel 53. Seeding gear 54 is rotatably arranged in the lower ending opening place of body feed tank 52 by rotating shaft. The upper end open of seed spout 57 is placed in the lower section of seeding gear 54. Seed in body feed tank 52 can be expelled to the upper end open of seed spout 57 by seeding gear 54. Second drive mechanism 55 includes the second drive sprocket the 551, second driven sprocket 552 and the second chain 553. Second drive sprocket 551 is in transmission connection by the second chain 553 and the second driven sprocket 552. Second drive sprocket 551 is set on the wheel shaft of the second traction wheel 53 circumferentially fixedly, and the second driven sprocket 552 is set on the wheel shaft of seeding gear 54 circumferentially fixedly. When outside walking arrangement tractor seeder advances, second traction wheel 53 rotates, the second drive sprocket 551 on second traction wheel 53 is along with rotating together, second drive sprocket 551 drives the second driven sprocket 552 to rotate, second driven sprocket 552 drives seeding gear 54 to rotate, in the process that seeding gear 54 rotates, the seed in body feed tank 52 being derived the upper end open to seed spout 57, seed is flowed in duck-beak type seeder 7 in the effect of self gravitation then through by seed spout 57. In the present embodiment, the seed in body feed tank 52 can be broken up when seeding gear 54 rotates, to prevent blocking seed spout 57.

As it is shown on figure 3, seeder of the present invention also includes two line parts 10. Two line parts 10 are respectively placed in the both sides, lower end of frame 1, and these two line parts 10 are for ruling in the both sides of frame 1. Which soil operating personnel can be clear that on finished kind, which soil is waited to sow by the lines that part 10 of ruling marks, it is possible to effectively prevent some soil from being wasted seed by repeat sowing.

The above, it it is only presently preferred embodiments of the present invention, not the present invention is done any pro forma restriction, according to any simple modification, equivalent variations and modification that above example is made by the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
