Air-suction vibration disk type field precise seeder for grain

Abstract

The invention discloses an air-suction vibration disk type field precise seeder for grains, and the seeder provided by the invention is mainly used for precise field sowing and seedling culture for small and medium particle grains of irregular shapes, such as super rice and the like. The air-suction vibration disk type field precise seeder for grains comprises a field travelling rack, a power source, a negative and positive air pressure source, a vibrated seed disk mechanism, a hand-held profiling sucking disk and a control unit, wherein the vibrated seed disk mechanism and the negative and positive air pressure source are installed on the field travelling rack; power is provided by a small gasoline engine; seeds are subjected to upward throwing movement to be mutually separated under theshock excitation of the vibrated seed disk; a seed disk vibration parameter is reasonably regulated, thus the seeds are in a 'boiling' moving state, thereby obviously enhancing the mobility, and reducing the seed adsorption resistance; a sucking disk panel is provided with profiling adsorption holes; and the shapes and arrangement modes of the adsorption holes can be changed according to different requirements of sowing objects. According to the invention, the precise field sowing and seedling culture for small-particle grains can be realized, the sowing effect and uniformity can be effectively improved, the seedling culture cost is lowered, requirements on seed sizes are low, and the seeds can be prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of precision seeding, and in particular relates to an air-suction vibrating disc precision seeder for grain fields. Background technique [0002] Sowing is an important technical link in the agricultural production process, and the seeder is the core component for realizing mechanized precision sowing. In recent years, the planting area of ​​super rice in my country has continued to expand. Compared with conventional rice, super rice has the advantages of tall plant type, thick stalk, strong tillering ability, large panicle and many grains. Growth, forming a high-yield population structure, planting 5000-7000 holes less than conventional rice per mu on average, which puts forward a higher standard for sowing seedling technology, requiring the sowing accuracy to be increased from 3-5 grains / hole to 1-2 grains / hole . At present, the overall level of rice planting mechanization in my country is still relatively...

AI Technical Summary

Problems solved by technology

[0003] The present invention is to realize the field precision seedling sowing of grains such as super rice with irregular shape and medium and small grains, so as to solve the problem of poor sowing uniformity and low efficiency of artificial seedling cultivation in the field, and the cultivated seedling trays are prone to missing insertion when machine transplanting is carried out. However, the cost of industrialized seedling cultivation is high, and it is not suitable for the difficulties of agricultural production in my country.
