Sowing-fertilization linked ground wheel profile driving device

Abstract

The invention belongs to the technical field of a sower in agricultural machinery and relates to a sowing-fertilization linked ground wheel profile driving device. The sowing-fertilization linked ground wheel profile driving device comprises a transmission system and a ground wheel profile driving unit. The transmission system comprises a wheat seed sowing shaft, a wheat seed sowing device, a fertilization shaft, a fertilization device, a transition shaft and a rapeseed sowing device. The ground wheel profile driving unit comprises a ground wheel group, a ground wheel transmission chain wheel, a profiling rack assembly, a middle transmission chain wheel, a middle shaft, a support assembly and a turning gear case assembly. The sowing-fertilization linked ground wheel profile driving device has a simple structure and reliable performances, is suitable for the basically-flat ground with small uneven parts, greatly reduces a slippage rate, reduces a miss-sowing rate, realizes linkage of sowing and fertilization of crops such as rape and wheat, and avoids seedling breaking and fertilization stopping in sowing. The sowing-fertilization linked ground wheel profile driving device can be used as a sowing and fertilization driving device for a plurality of sowing machines.

Description

technical field [0001] The invention belongs to the technical field of seeders in agricultural machinery, and in particular relates to a profiling drive device for ground wheels linked with sowing and fertilization. It is simple in structure and reliable in operation, and can adapt to large and small unevenness of the surface, and realizes the linkage of sowing and fertilization of rapeseed, wheat and other crops. Background technique [0002] At present, the power of the seed and fertilizer discharge devices of domestic sowing operation tools mainly comes from the ground wheel. Under the traction of the tractor, the ground wheel drives the seeding and fertilizer discharge devices to achieve the uniformity and consistency of seeding and fertilization of the seeder. Therefore, the ground wheel is the key factor affecting the seeding performance of the seeder. The spike-toothed ground wheel device equipped with existing seeding machines, on the one hand, because the depth of ...

AI Technical Summary

Problems solved by technology

The spike-toothed ground wheel device equipped with existing seeding machines, on the one hand, because the depth of the ground wheel is fixed through the threaded hole, the ground wheel cannot adapt to the fluctuation of the ground surface, which affects the quality of sowing; Increase

However, for land wheels running on rice stubble fields or dry land covered by a large amount of straw, due to sticky soil, uneven surface, more straws or weeds, etc., problems such as land wheel clay blockage, slippage and overhead problems often occur, resulting in sowing In the process, the phenomenon of broken seedlings and fertilizers will affect the sowing quality of the equipment. In severe cases, it will even cause severe wear and tear on the parts of the planter and the loss of the sowing function.
