Description

Technical Field

[0001] This utility model relates to a seeding mechanism, and in particular to a high-speed seeding device suitable for large seeds such as cotton, corn or sunflower. Background Technology

[0002] Existing seeding mechanisms, especially air-suction roller seeders, use a roller assembly to pick up seeds. This assembly consists of a hollow shaft, an air-suction seed tray, a seed distribution tray, and a duckbill seeder. The seed tray has evenly distributed seed suction holes on its surface. The seeds are adsorbed by negative pressure. As the seed tray rotates with the roller, the seed suction holes adsorb the seeds under negative pressure. After reaching the seed unloading area, the air cut-off device cuts off the negative pressure, and the seeds are guided by the seed distribution tray to the duckbill for seeding.

[0003] When the machine is operating at high speed, the excessively high linear speed of the seed suction disc leads to insufficient seed filling time and poor seed filling effect, which can easily cause missed sowing and double sowing, seriously affecting the sowing quality. In order to ensure the sowing quality, it is necessary to sacrifice the efficiency of operation.

[0004] Therefore, a high-speed seeding and hill-planting device capable of handling multiple tasks was developed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-speed seeder that can significantly improve work efficiency while ensuring seeding quality.

[0006] This invention employs a secondary seed-guiding mechanism within an enlarged outer ring belt, which increases the diameter of the seeder and relatively reduces the size of the seed-collecting tray and negative pressure chamber. This significantly reduces the linear velocity of the seed-collecting tray, ensuring seed-collecting accuracy and enabling precise sowing. Furthermore, the secondary seed-guiding mechanism extends the seed delivery time, ensuring seed transfer quality and increasing sowing speed.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: it includes a seed chamber, a seed-taking mechanism, and a seed-dispensing mechanism. The seed-dispensing mechanism includes a front fixing plate (8), a rear fixing plate (1), a belt (2), and a duckbill (15). The seed-taking mechanism includes a hollow negative pressure shaft (11) and a seed-taking disc (7). The seed-taking disc (7) is provided with a seed-taking hole (7-1).

The feature is that: the seed-taking disc (7) and the seed-dispensing machine... A secondary seed guiding mechanism (3) is provided between the structures. The secondary seed guiding mechanism (3) includes annular clamps (3-1) on both sides and a second seed guiding plate (3-2) between the annular clamps (3-1). The second seed guiding plate (3-2) is a plate with a "spoon" shaped cross section that is radially erected between the second seed guiding plates (3-2).

[0011] Furthermore, the above-mentioned secondary seed guiding mechanism (3) is preferably composed of several independent individuals. The annular clamp (3-1) has at least one arc-shaped plate on one side. Each plate is provided with at least one second seed guiding plate (3-2) to form an independent individual. Several independent individuals are combined to form the secondary seed guiding mechanism (3).

[0012] Furthermore, the radial channel of the above-mentioned secondary seed guiding mechanism (3) is provided with a trumpet-shaped opening with a larger inner opening and a smaller outer opening on both the left and right sides.

[0013] Furthermore, a limiting pressure plate (4) is preferably provided between the above-mentioned secondary seed guiding mechanism (3) and the seed taking plate (7). The limiting pressure plate (4) includes an annular base plate (4-1), and a vertical first seed guiding plate (4-2) is provided on the annular base plate (4-1). The first seed guiding plate (4-2) divides the annular base plate (4-1) into several radial channels.

[0014] The limiting pressure plate (4) is located inside the secondary seed guiding mechanism (3). The secondary seed guiding mechanism (3) and the limiting pressure plate (4) have the same number of radial channels, and the outer opening of the radial channel of the limiting pressure plate (4) is connected to the inner opening of the radial channel of the secondary seed guiding mechanism (3).

[0015] Furthermore, the seed-taking plate (7) on the inner or outer side of the seed-taking hole (7-1) is preferably provided with a seed-disturbing device (6), which is a protrusion on the seed-taking plate (7), such as an upright plate or a finger.

[0016] Furthermore, the seed chamber on the trajectory line of the seed hole (7-1) of the seed tray (7) is preferably equipped with at least one of a forced seed unloading blade (5) and a seed cleaning saw (9).

[0018] Compared with existing technologies, this invention can significantly increase the diameter of the seeding roller by setting a secondary seed guiding mechanism, and set more seeding nozzles on the seeding roller, while relatively reducing the diameter of the seed picking tray. At the same sowing speed, the linear speed of the seed picking tray can be greatly reduced, the seed picking time can be extended, the reliability of seed picking can be guaranteed, and thus the sowing speed and work efficiency can be improved, and the sowing quality can be improved.
