Abstract

The utility model discloses a potato harvester, which comprises a frame, a suspension frame, an excavation shovel, a profile modeling wheel, a lifting chain, a swaying sieve, a transmission box and a transmission mechanism. The potato harvester is characterized in that the profile modeling wheel is capable of precisely locating the excavation position and rotary cutting knives remove weeds on two sides of the frame, thereby improving operating speed and preventing potatoes on two sides of the frame from leaking. The arch excavation shovel reduces the amount of earth being shoveled, improves the cleanliness rate and prevents the potatoes from being damaged. The chain link type lifting chain with a liner bushing is strong in flexibility, wear resistant, pulling durable, damage-free to potatoes and difficult to be fractured. The transmission box utilizing two-gear shifting fork to adjust the gear is applicable to both dry soils and moist soils, thereby improving the production efficiency. The staged swaying sieve lowers damage rate to potatoes in two-time separation and fully meets the requirements of potato planting and long-term storage of potatoes after harvesting. A main transmission shaft connected by a spline housing is stable in operation and free of operation failure. A double dust-resistant supporting chain wheel prolongs maintenance period and solves the problem of frequent maintenance of other machine models.

Description
