A simple hand seed sowing tool tray is an agricultural machinery used to evenly sow seeds into the soil or in a tray. The design of these tools aims to reduce the labor intensity of farmers, improve sowing efficiency and accuracy, while reducing seed waste.
The working principle of a manual seeder usually involves the collaborative work of the following key steps and components:
1：Seed storage: Seeds are placed in a container or storage box, typically located above the seeder for easy flow and distribution.:
2：Seed flow control: There is a mechanism inside the seeder to control seed flow, which can be a simple funnel, a perforated plate, or a more complex metering device. This mechanism ensures that seeds flow towards the sowing point at a certain rate and quantity.
3：Sowing disk or sowing wheel: This is the core part of the seeder, usually a disk with holes or grooves. As the disk rotates, seeds are dropped into the soil through the holes or grooves. The design of the seeding tray determines the number of seeds released and the spacing between seeds per rotation.
4：Soil trencher: Under the sowing tray, there is usually a trencher or plow blade used to form grooves or holes on the soil surface so that seeds can be placed at the appropriate depth in the soil.
5：Seed placement: Seeds are placed into the soil through grooves or holes formed by a trencher from a sowing tray. The rotation speed of the sowing disc and the design of the trencher jointly determine the depth and spacing of sowing.
6：Soil Cover: After sowing, the soil needs to be covered to protect the seeds and maintain soil moisture. This is usually accomplished through a covering device or compaction wheel, which can be part of the seeder or a separate mechanical operation.
7：Manual operation: The entire sowing process is usually manually operated by farmers, who push or pull the seeder to control the speed and direction of sowing. Some seeders may be equipped with wheels for easy movement in the field.
8：Adjustment and calibration: In order to adapt to different seed types and sowing requirements, seeders can usually adjust sowing depth, sowing spacing, and sowing rate. This may involve adjusting the rotation speed of the seeder, the position of the trencher, or the overall height of the seeder.
The design of a hand seeder can be very simple, including only basic seed distribution and dispensing mechanisms, or more complex, including precision metering devices and adjustable components to adapt to different sowing conditions and crop needs. Although manual seeders require manual operation, they are still an effective seeding tool in small-scale agriculture and specific situations.
