Above-mentioned clipping seeding unit, there is circular hole in described folder kind disk center, circular hole is corresponding with the circular flat cam, and folder kind of a sheet is a strip sheet, and the middle part is a round bar, round bar is fixed on folder kind of dish upper surface by snap ring, the two ends of folder kind of sheet have horizontal compressing tablet and rotor respectively, and rotor is pressed on the annular ring of circular flat cam, and compressing tablet surpasses the outer circumferential edges of folder kind of dish, be pressed on the side plane of disc holder, a side of folder kind of sheet has back-moving spring.
Above-mentioned clipping seeding unit, the lateral surface of described seed plate have a plurality of grids that have lath to be divided into, and these grids are that the center is radial arrangement along the seed plate circumference with the rotating shaft, and the position of each grid is corresponding with the folder kind sheet of disc holder opposite side.
Adopt the clipping seeding unit of this structure, folder kind of dish and seed tray rotate with rotating shaft, folder kind of sheet clamping seed in rotation enters seed the sowing chamber again, is sowed by below, sowing chamber, this method of clamping is not simply, reliably, can produce the broadcast leakage phenomenon, can not hinder kind yet, knock seed, not need supporting vavuum pump, reduce the power consumption of engine, save the energy, reduced peasant's financial burden.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the circular flat cam schematic diagram that amplifies.
Mark is as follows among the figure: housing 1, disc holder 2, seed chamber 3, sowing chamber 4, folder kind of dish 5, seed plate 6, rotating shaft 7, folder kind of sheet 8, sowing port 9, sowing opening 10, seed inlet 11, plane cam 12, snap ring 13, rotor 14, compressing tablet 15, back-moving spring 16, grid 17.
Embodiment
Show among the figure that the utility model is made up of housing 1, disc holder 2, seed chamber 3, sowing chamber 4, folder kind of dish 5, seed plate 6, rotating shaft 7.
Show among the figure, the end face of facing seed chamber 3 at the middle part of disc holder 2 has circular flat cam 12, the cylindrical annular ring of plane cam 12 is the height changing unit of cam, its peak drops to minimum point gradually along circumference, minimum point and peak are the step of vertical connection, in plane cam 12 annular rings is the plane, and its center is the axis hole of disc holder 2, and rotating shaft 7 passes from axis hole.
Show among the figure that a plurality of folder kind sheets 8 are arranged in seed chamber 3, folder kind of sheet 8 is that the center is radial arrangement along folder kind of dish 5 circumference with rotating shaft 7.Folder kind of a sheet 8 is a strip sheet, the middle part is a round bar, round bar is fixed on folder kind of dish 5 upper surfaces by snap ring 13, the two ends of folder kind of sheet 8 have horizontal compressing tablet 15 and rotor 14 respectively, rotor 14 is pressed on the annular ring of circular flat cam 12, compressing tablet 15 surpasses the outer circumferential edges of folder kind of dish 5, is pressed on the side plane of disc holder 2, and a side of folder kind of sheet 8 has back-moving spring 16.When folder kind of sheet 8 rotated along with folder kind of dish 5, the rotor 14 of folder kind of sheet 8 slided on plane cam 12, changed driving folder kind of sheet 8 and rotate with the height of plane cam 12, and folder is planted the compressing tablet 15 of sheet 8 other ends also just along with rotation.When compressing tablet 15 rotates, just can push down seed, allow seed also rotate, when turning to the sowing port 9 on seed chamber 3 tops, seed is discharged in the sowing chamber 4 with it; Rotor 14 promptly falls into the minimum point of plane cam 12 subsequently, under the effect of back-moving spring 16, compressing tablet 15 upwards rotates, and leaves disc holder 2 planes, is pivotally lowered into the storage seed position of seed chamber 3 bottoms always, after entering seed chamber 3 and filling the part of seed, along with rotor 14 slides to peak on plane cam 12 gradually, rotor 14 upwards rotates, and the compressing tablet 15 of the other end begins again to press down, the clamping seed repeats above-mentioned seeding action.The folder kind sheet 8 of these circumferential arrangement is do action in this manner all, successively seed is entered sowing chamber 4 from sowing port 9.
