Large-grain seed directional positioning precision seeding device

Abstract

The invention relates to the technical field of agricultural machinery, and particularly relates to a large-grain seed directional positioning precision seeding device. The large-grain seed directional positioning precision seeding device comprises a seed supply mechanism with a plurality of seed supply openings, wherein the output end of the seed supply mechanism is connected with a plurality ofgrooved wheel covers distributed corresponding to the seed supply openings; the inner side of each grooved wheel cover is rotationally connected with a seed falling grooved wheel; and the plurality ofseed falling grooved wheels are fixedly connected in the circumferential direction. The plurality of seed falling grooved wheels are arranged at the output end of the seed supply mechanism; the plurality of seed falling grooved wheels are fixedly connected in the circumferential direction; an included angle is formed in the circumferential direction; in the moving process of the equipment, the seed falling grooved wheels rotate; seeds in the plurality of seed falling grooved wheels sequentially fall off; the seeds are not in one row and are in one inclined line distribution; the falling angleon the ground is controlled according to a seed discharging mechanism; the controllable seed cotyledon growth direction is ensured; the seed falling grooved wheels are arranged at the tail end of theseed supply mechanism, so that the speed is low when the seeds slide down; and the position and the angle are controllable; the precision is high.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a device for directional positioning and precision sowing of large seeds. Background technique [0002] The cultivation of various crops and even the cultivation of various flowers are increasingly adopting plug seedling seeding or industrial seedling raising technology. In order to solve the problem that seeds have good growth conditions in the early stage of production, artificial 45° directional placement is usually used. Seeding, low operating efficiency, easy to fatigue, it is of great significance to develop a large seed directional positioning precision sowing device, and cultivate standardized seedlings with consistent cotyledons. [0003] In the prior art, the seedling precision seeding machine is generally used for seeding, but the existing equipment is generally positioned to plant seeds in rows, and the angle of inclination of 45° is easy to cause the g...

Problems solved by technology

[0002] The cultivation of various crops and even the cultivation of various flowers are increasingly adopting plug seedling seeding or industrial seedling raising technology. In order to solve the problem that seeds have good growth conditions in the early stage of production, artificial 45° directional placement is usually used. Seeding, low working efficiency, easy to fatigue, it is of great significance to develop a large-seed seed directional positioning precision seeding device, and cultivate standardized seedlings with consistent cotyledons

[0003] In the prior art, the seedling precision seeding machine is generally used for seeding, but the existing equipment is generally positioned to plant seeds in rows, and the angle of inclination of 45° is easy to cause the gap between the two rows of seeds at the wrong position. When growing to a certain size, there will be mutual obstruction between leaves, such as attached figure 1 As shown in (a), it will interfere with the growth of seedlings to a certain extent and affect the quality of seedlings
