Description

Profiling land wheel assembly of seeder

Technical Field

The utility model belongs to the technical field of agricultural machinery, and relates to a profiling land wheel assembly of a seeder.

Background

The existing seeder which relies on land wheels to provide power drives the seeding wheels and the fertilizer discharging wheels to perform seeding and fertilizer discharging operations. The existing seeder land wheels lack automatic adjusting function, cannot adapt to topography fluctuation, so that the straw cleaning effect of the seeder is reduced, the seeder is dragged to pile and block, the land wheels are easy to separate from the ground due to the fluctuation of the ground in the use process, and once the land wheels are suspended, the seeding wheels and the fertilizer discharging wheels cannot rotate, so that seeding and fertilizer discharging cannot be performed. The operation quality of the seeder is seriously influenced, the emergence rate of corresponding crops is low, and based on the low emergence rate, a profiling land wheel assembly of the seeder is studied to solve the problem.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, and provides the profiling land wheel assembly of the seeder, which can automatically adjust the position of the land wheel on the undulating ground, so that the land wheel can always walk on the ground, the operation effect of the seeder is ensured, and the straw blockage of the seeder is reduced.

The utility model is realized by the following technical scheme: the utility model provides a seeder profile modeling land wheel assembly includes profile modeling four poles and land wheel extension board combination, spring damping device combination, hydraulic pressure regulation combination, its characterized in that: the lower part of the land wheel support plate is provided with a land wheel and positioned through a bearing seat; the middle part of the ground wheel support plate is connected with the rear side of the profiling four-bar and can rotate around a shaft, an upper pin shaft is arranged at the upper part of the ground wheel support plate, a spring damping shock absorber is arranged on the upper pin shaft in the downward direction, the lower part of the spring damping shock absorber is connected with a lower pin shaft, the lower pin shaft is connected with the rear part of the inner support plate, and the front part of the inner support plate is connected with the rear part of the profiling four-bar; the front part of the profiling four-bar is connected with a connecting side plate, a hydraulic cylinder supporting seat and an upper hanging lug are welded on the upper parts of the connecting side plate and the hanging plate, an oil cylinder is arranged on the upper hanging lug, the other end of the oil cylinder is connected with a lower hanging lug, and the lower hanging lug is welded on the profiling four-bar.

The utility model is used on a seeder, the height of the land wheel is quickly adjusted by utilizing the hydraulic cylinder, and the utility model is suitable for different working modes of ridge culture flat-working; the land wheel has elasticity and shock attenuation effect under the effect of spring damping bumper shock absorber, runs into the high and low relief road surface land wheel and can reciprocate, can guarantee that the land wheel is hugged closely ground all the time, ensures that seeder seeding and fertilizer discharging power is uninterrupted, and the land wheel vibration can weaken gradually under the effect of damping, reduces to cause seeder frame vibration because of the land wheel reciprocates to ensure seeding, fertilizer discharging effect fruit, improve and broadcast deep stability assurance clear straw effect, reduce straw jam.
