Plant underground harvester

Abstract

The invention relates to a plant underground harvester which comprises a rack, land wheels, a gearbox, a scraper knife and two circulation chain screens. A separation impurity removal chain screen isarranged in the middle of the chain screen stacked portions, the impurity removal chain screen and a two-chain screen are arranged in a crossed mode, impurity removal chain screen shaft end gears areconnected through a bevel gear, the harvester is provided with two circulation chain screens, a chain support or a vibration wheel is arranged in the middle of the chain screens, sundries are separated rapidly, particularly, by arranging the impurity removal chain screen, seedlings, grass and sundries are separated from fruits, in addition, by arranging a soil pressing roller, soil blocks in harvested fruits and on the earth's surface are crushed so that separation can be facilitated, by arranging a storage box and adopting an oil pressing device, the harvester is reasonable in mechanical mechanism design, high in harvesting purity, thorough in seedling and weed separation, and the whole harvesting process is completed at a time.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an underground crop harvester. Background technique [0002] Underground fruits such as ground ring, Codonopsis pilosula, Bupleurum, potato, and sweet potato are mainly harvested by manual excavation. However, with the development of industrialization, large-scale and intensive operations, the production cost of manual operation is high and the efficiency is low. It is difficult to adapt to the needs of production and industrialization development. At present, there are also enterprises and manufacturers developing such machines. The applicant researched and improved 2015207967345 self-propelled ground ring harvester and 2015207973261 a drag-type ground ring harvester. Due to the limitation of land conditions and heavy mechanical equipment, it is difficult to adapt , can not harvest corners and depressions, etc., serious rolling, picking up is not clean, and the separation of grass and...
