Embodiment 1 referring to fig. 1 and 2, a deformed hole forced seeding apparatus includes a housing, a seeding wheel and a seeding cam; the housing comprises a left housing 1 and a right housing 19; the seed discharging cam 11 is fixed on the left shell 1 through a bolt 13, and a nut 12 is arranged on the bolt; the seed sowing wheel comprises a left seed sowing wheel 2, a right seed sowing wheel 16 and six groups of multi-stage type hole matching parts, wherein the six groups of multi-stage type hole matching parts are uniformly distributed on the periphery of the seed sowing wheel; the seed sowing wheel is fixed on the seed sowing plate through a fixing bolt 21; a groove is arranged in the circumference formed by the left seed sowing wheel 2 and the right seed sowing wheel 16; the groove is internally provided with a multistage type hole matching part.
In the present embodiment, referring to fig. 3, the multi-stage bore coupling includes a first-stage bore coupling 10, a second-stage bore coupling 5, a third-stage bore coupling 4, and a fourth-stage bore coupling 3. The primary orifice coupling 10 passes through the base 17 and forms a coupling with the base 17. The primary hole coupling piece 10 penetrates through the secondary hole coupling piece 5 to form coupling; the secondary type hole coupling piece 5 penetrates through the tertiary type hole coupling piece 4 to form coupling; the tertiary type hole coupling piece 4 penetrates through the quaternary type hole coupling piece 3 to form coupling; the quaternary bore coupling 3 is coupled through the bore coupling housing 20.
Specifically, the second-stage hole matching part 5 is connected to a base 17 through a second-stage matching part spring 6 in a tensioning mode, the third-stage hole matching part 4 is connected to the base 17 through a third-stage matching part spring 7 in a tensioning mode, and the fourth-stage hole matching part 3 is connected with the base 17 through a fourth-stage matching part spring 8 in a tensioning mode; the primary hole matching part 10 is connected to a base 17 through a seed metering spring 9 in a tensioning manner, and simultaneously, a bearing 15 is connected to a seed metering cam 11 in a tensioning manner; the bearing 15 is fixed to the primary orifice fitting 10 by a pin 14. Wherein, the second-stage matching part spring 6, the third-stage matching part spring 7 and the fourth-stage matching part spring 8 have different rigidity coefficients and are increased step by step.
In this embodiment, the housing 20 of the hole matching part is connected with the oil port 18 through a thread, and the oil port 18 is externally connected to a hydraulic system of the tractor.
When the deformed hole forced seeding apparatus provided by the invention works, the oil port 18 is externally connected to a hydraulic system of a tractor, and when the size of the operation hole corresponding to the seeding apparatus needs to be changed, an operator adjusts the size of the hole by adjusting the pressure of hydraulic oil.
