The potato harvester

The potato harvester is a special harvesting machine for harvesting potato root crops such as potatoes and sweet potatoes. It can also harvest peanuts, carrots, onions, garlic and other stem crops and agricultural products. It can complete excavation, lifting, cleaning, separation, laying, etc. Multiple assignments. The machine has advanced principles, good adaptability and high reliability. This machine works with a 20-60 horsepower tractor and is mainly used for harvesting, piles, and other processes of underground potatoes such as potatoes, sweet potatoes, peanuts, etc. The net recovery rate is greater than 99% and the peel rate is less than 1%. It is suitable for sandy soil, sandy loam, medium cohesive soil and other soil qualities.

The potato harvester is connected to the transmission shaft of a small four-wheel tractor, and the shovel is driven back and forth by the eccentric block and the connecting rod on the main transmission shaft, and then the gear at the left end of the transmission shaft drives the transmission gear on the bridge shaft and changes the transmission direction. Then the main drive shaft of the separation chain is driven by the chain, and the eccentric block at both ends of the main drive shaft drives the vibrating screen to shake up and down. Under the tractor, the potatoes (garlic, sweet potatoes, etc.) excavated by the digging shovel are laid on the separation chain. The soil falls under the separation chain under the rotation of the separation chain. The potatoes (garlic, sweet potatoes, etc.) and The unfalling soil blocks fall on the vibrating screen on the separation chain, and are cleaned and separated again and placed on the ground behind the machine. Special forced vibration system, good separation effect and strong adaptability. The net yield is high, the destruction rate is low, and the cost recovery is fast. Extracting the mulch film remaining in the soil will not affect the growth of crops in the next season.
