Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to a pneumatic centralized seed supply device for precise hole seeding of corn. Background Art

[0002] Hole seeding is an agricultural planting technique, the main feature of which is to sow seeds into holes at specified row and plant spacings and sowing depths. This sowing method can ensure that the seedlings are evenly distributed in the field and improve the emergence ability. Hole seeding has a wide range of applications and can be applied to a variety of crops, including corn, cotton, sugar beets, sunflowers, etc. Before sowing, it is usually necessary to prepare the land and select plots with convenient drainage, irrigation, sufficient sunlight, and deep soil for planting.

[0003] For corn hole sowing, the existing corn hole sowing device usually includes dozens of sowing units in order to improve sowing efficiency, and each sowing unit must be equipped with a seed box and a seed meter. When the existing seed meter discharges seeds, the seed movement speed is low, and the seeds usually fall into the seed inlet of the corresponding sowing unit only by gravity. This requires that the seed meter and the seed box must be set directly above the corresponding sowing unit, and the distance between the sowing units is large, which leads to a large distance between each seed meter and each seed box, resulting in a large overall mass and volume of the seeder, which is not convenient for the machine to be folded and stored, and is inconvenient for transportation and storage. The machine is inconvenient to operate and maintain, and the transmission structure is complex and inefficient. Utility Model Content

[0004] In view of this, it is necessary to provide a pneumatic centralized seed supply device for precision hole seeding of corn to solve the technical problems that the various seeders and seed boxes of the existing corn hole seeding device cannot be centrally arranged, resulting in a large overall mass and volume of the seeder, inconvenient folding and storage of the machine, inconvenient transportation and storage, inconvenient operation and maintenance of the machine, and a complex transmission structure and low efficiency.

[0009] In some embodiments, each of the seeding devices includes a seeding shell, a turntable and a rotating drive component. The seeding shell is located below the hopper. The upper end of the seeding shell is provided with a feed inlet connected to the outlet of the hopper, and the lower end of the seeding shell is provided with a discharge port. The turntable is rotatably arranged in the seeding shell, and a plurality of seed grooves are formed on the outer side wall of the turntable. The rotating drive component is connected to the turntable and is used to drive the turntable to rotate.

[0010] In some embodiments, each of the seed metering devices further includes a rotating shaft, which is rotatably disposed on the seed metering housing, and the turntable is fixed on the corresponding rotating shaft.

[0011] In some embodiments, each of the seed metering devices shares a rotating shaft, and the rotating drive member is connected to the rotating shaft and is used to drive the rotating shaft to rotate.

[0012] In some embodiments, the rotary drive member includes a rotary drive motor and a reducer, the output shaft of the rotary drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the rotating shaft.
