Structure and Working Principle

• Structure
  • Frame: It is made of sturdy steel, it serves as the main structure of the machine, providing support and stability, and is used to connect each component and ensure a secure connection with the tractor.
  • Seeding Device: It often includes a seed tank, a seeding mechanism, and a depth - control device. The seed tank is used to store potato seeds, and the seeding mechanism can accurately deliver the seeds to the soil at a set spacing and depth. The depth - control device can adjust the seeding depth according to different soil conditions and planting requirements.
  • Fertilizer Spreading Device: Consists of a fertilizer tank, a fertilizer - spreading mechanism, and a conveying system. The fertilizer tank holds the fertilizer, and the conveying system transports the fertilizer from the tank to the fertilizer - spreading mechanism, which then evenly spreads the fertilizer into the soil at a certain rate.
  • Ditching and Ridging Mechanisms: The ditching mechanism is used to open furrows in the soil before seeding and fertilization, providing space for seeds and fertilizer. After seeding and fertilization, the ridging mechanism can cover the seeds and fertilizer with soil and form ridges, which is beneficial for potato growth and water management.
  • Transmission System: Connects the power output of the tractor to each working component, usually including gears, chains, or belts, etc., to transfer the rotational power of the tractor to the seeding device, fertilizer - spreading device, ditching mechanism, and other components, enabling them to operate.
• Working Principle: The tractor provides power to drive the machine forward. During the forward movement, the ditching mechanism first opens furrows in the soil. Then, the fertilizer - spreading device evenly spreads the fertilizer into the furrows according to the set amount. Immediately after that, the seeding device accurately places the potato seeds into the furrows at a certain spacing. Finally, the ridging mechanism covers the seeds and fertilizer with soil to complete the planting process.

Advantages

• High Efficiency: By integrating seeding and fertilization into one operation, it can complete two tasks simultaneously, greatly improving the planting efficiency compared to separate seeding and fertilization operations, saving a lot of time and labor.
• Precision: Both the seeding device and the fertilizer - spreading device can be precisely adjusted. The seeding device can ensure accurate seed spacing and depth, and the fertilizer - spreading device can control the amount of fertilizer applied, ensuring that each potato seed has an appropriate growth environment and sufficient nutrient supply.
• Good Adaptability: It can be adjusted according to different soil conditions, planting varieties, and agronomic requirements. For example, the seeding depth, fertilizer amount, row spacing, and plant spacing can all be adjusted to adapt to different planting needs in various regions.

Models and Specifications

• 2 - row Potato Seeder and Fertilizer Spreader: Generally, it can be matched with tractors of 25 - 35 horsepower. The working width is usually about 1 - 1.5 meters, and the seeding depth can be adjusted in the range of 5 - 15 centimeters, and the fertilizer - spreading amount can be adjusted according to different fertilizers and planting requirements.
• Single - row Potato Seeder and Fertilizer Spreader: Such as the Chunming - brand potato planter, which is hand - operated and equipped with a diesel engine. It is suitable for single - row planting, has high flexibility, and is suitable for complex terrains such as mountains and hills. The plant spacing, fertilizer amount, and medicine amount can be freely adjusted according to local planting modes and user needs. The current model Hensen potato seeder and fertilizer spreader 2 in 1 is single row type.
