Abstract
The invention discloses a two-stage seed metering and sowing machine for natural grassland re-sowing, belonging to the technical field of agricultural machinery. The device comprises a stirring unit, a first-stage seed box, a remaining seed receiving box, a second-stage seed box, an eccentric shaft structure, a vibrating sieve plate unit, an eccentric shaft chain wheel, a first-stage seed metering unit, a stirring shaft chain wheel and a first-stage seed metering unit transmission chain wheel. After seeds enter the first-stage seed box, the stirring shaft chain wheel drives a plurality of rows of flexible brushes on the stirring shaft to rotate, so as to prevent the phenomenon that the seeds with poor flowability in the first-stage box are underlay-free. The seeds discharged from the first-stage seed box can uniformly flow in a split manner into four seed metering ports of the second-stage seed box via two sieve plates of the vibrating sieve plate unit, to solve the problems of a general seed metering unit such as large discharge capacity and unstability of small-size seeds of such as pasture. The vibrating sieve plate unit applies the eccentric shaft structure so that the sieve plate can reciprocate. The remaining seed receiving box can receive the remaining seeds that fail to fall into the second-stage seed box from the vibrating sieve plate.

The one-level dispenser adopts the outer groove wheel seeding unit.
Be uniform-distribution with many row's Flexible brushes on the shaft circumference of agitating device.
One-level kind case and secondary kind case are the height layered arrangement, and the seed of from one-level kind case, discharging can evenly be diverted in four sowing ports of secondary kind case through two sieve plates of oscillating screen plate device.
Surplus kind of inoculating hood entrance location is lower than the outer of secondary kind case and oscillating screen plate.
Beneficial effect of the present invention is:
(1) one-level kind case and twice minute kind of secondary kind case, the seed that can let outer groove-wheel discharge is still less more even.
(2) agitating device in the one-level kind case can solve the built on stilts phenomenon of seed in the one-level kind case effectively.
(3) the oscillating screen plate device can be good at solving the problem of the mobile difference of seed, prevents that seed from causing sieve pore blockade on sieve plate.
(4) surplus kind of inoculating hood can receive seed unnecessary on the sieve plate, and it is crowded to prevent that too much seed from causing on sieve plate.
