Harvester for rhizomatic crops

Abstract

The invention relates to a crop harvesting machine, in particular to a harvester for rhizomatic crops. The harvester comprises a rack, a compacted vibration type digging device and a pressure supporting type conveying and cleaning device, wherein the compacted vibration type excavating device comprises vegetable picking wheels, digging shovels and a digging shovel angle adjusting mechanism, wherein the digging shovels and the vegetable picking wheels are arranged at the front part of the rack; the digging shovels are arranged in pairs; each pair of digging shovels comprises two digging shovels; the two digging shovels are symmetrically arranged to form a wedge shape; one vegetable picking wheel is arranged above each pair of digging shovels; the pressure supporting type conveying and cleaning device comprises a sling chain and a conveying chain; the sling chain and the conveying chain are arranged at the middle part of the rack; the sling chain is located above the conveying chain and is fixed on the rack; a clearance is formed between the sling chain and the conveying chain. According to the harvester, angle adjustability of the digging shovels is realized, and the harvesting rate of the rhizomatic crops is improved.

Description

technical field [0001] The invention relates to a crop harvesting machine, in particular to a root crop harvesting machine. Background technique [0002] Rhizome crops include potatoes, sweet potatoes, peanuts, garlic, carrots, etc., which account for a large proportion of all crops in my country. Among them, beet is second only to sugarcane and ranks second in the sugar crops with high economic value. Its harvest is highly seasonal, labor-intensive, and takes up a lot of farming time. The lack of sugar beet harvesting machinery has seriously restricted the further development of the sugar beet industry. Harvesting operation is an important process in the sugar beet production process, and it is a key link to ensure the increase of sugar beet production and income. Harvesting machinery is an indispensable mechanical equipment for modern sugar beet agricultural production, which can greatly reduce the labor intensity of the sugar beet harvesting process, improve production...

AI Technical Summary

Problems solved by technology

Its existing defects are: (1) the angle of the excavation disc is fixed, but in the actual excavation process, the rhizome crops are not strictly grown in parallel ridges and rows. If the angle of the excavation disc is fixed, the excavation shovel The root crops will be directly cut up or missed, which greatly reduces the harvest rate of the root crops

(2) The structure of the lifting device is complicated, and it is troublesome to repair if a fault occurs during use, which reduces the working efficiency of the harvester
