A kind of unit row seeding machine

Abstract

The invention relates to the field of agricultural machinery equipment, and in particular relates to a seed metering single body for a plant-to-row drill seeder with high sowing efficiency. The seed metering single body comprises a seed metering deice and a seed storing device which are fixedly arranged on a machine body, wherein the seed metering device comprises an installing base, a seed metering opening is formed in one side of the installing base, a machine drives a rotating bevel gear, the upper part of the bevel gear is sequentially provided with a cone base and a hollow cone which are linked with the bevel gear, a tensioning roller is arranged at one side of the cone, the seed metering opening is formed between the cone and the tensioning roller, and a driving woven belt is packed outside the cone and the tensioning roller; the seed storing device comprises a glass seed storing sleeve and a seed storing hopper, and the lower part of the seed storing sleeve is tightly clamped with the top end of the cone. The seed metering single body provided by the invention has the advantages of being simple in structure, even in seeding, high in self-cleanliness, and small in seed damage.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a row seeder seeding unit with high seeding efficiency, small damage and high self-cleaning degree. Background technique [0002] During the trial planting period in the breeding area, the structure of the seeding unit of the drill used in conjunction with the drill machine is various, but it is usually a relatively complicated frame structure. The damage is large, and a large amount of seeds are often left in the seed storage device after the seeding work is completed. [0003] The plant row drill plays an important role in ensuring the smooth completion of the plant row sowing operation and improving the accuracy of the plant row comparison test in the cultivation stage of new agricultural varieties. At present, there is no machine specially suitable for row-by-row seeding breeding in China. The seeding device of the plot drill used in the trial ...

AI Technical Summary

Problems solved by technology

At present, there is no machine specially suitable for row-by-row seeding breeding in China. The seeding device of the plot drill used in the trial planting process in the breeding area cannot meet the sowing requirements of row-by-row seeding, and the damage to the seeds is serious. The uniformity cannot be guaranteed, and the requirement of self-cleaning cannot be better realized

Therefore, most of the existing breeding units still mainly use artificial sowing, low degree of mechanization, high labor intensity, and poor sowing effect, which affects the accuracy of breeding experiments to a certain extent and hinders the development of the breeding industry. Therefore, it is urgent to develop A self-cleaning degree, good seeding uniformity, simple structure, reliable operation, and a single seeding unit for plant row breeding plots
