Rhizomatic crop harvester

Abstract

The invention relates to a rhizomatic crop harvester. The rhizomatic crop harvester comprises a rack, a scraper knife located at the front end of the rack and a vibrating screen located on the rear middle portion of the rack; the two sides of the front end of the rack are each provided with a vertical rotating roller, gaps are reserved between the rotating rollers and rack, and the rotating rollers are connected with power shafts; at least one pair of annular child and mother sealing parts are arranged in the rotating rollers and located in gaps between bearing pedestals and bearing pedestal shafts, the exteriors of the child and mother sealing parts are in interference fit with the bearing pedestals, and the bearing pedestal shafts are arranged in central holes of the child and mother sealing parts; a rear ridge roller is arranged under the rear portion of the rack and hinged to the rack. The harvester is suitable for various soil types such as sandy soil, sandy loam soil and medium-viscosity soil; a three-wheel vibrating system is adopted, so that the crop and soil separation effect is good, the harvesting rate is higher than 99 percent, and the breakage rate is lower than 1 percent; the rear ridge roller and a collection baffle are designed, so that crop damage is reduced, crops are concentrated after falling to the ground and easy to harvest; grass cannot block the harvester, soil leakage is fast, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a rhizome crop harvester. 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. In particular, potatoes. Since January 2015, the country has begun to promote the strategy of turning potatoes into a staple food, becoming the fourth largest staple food crop after rice, wheat, and corn. The planting area of ​​potatoes will gradually expand to 150 million mu. It is estimated that by 2020 , More than 50% of potatoes in my country will be consumed as staple food. Traditional agriculture mainly relies on manual digging to harvest root crops, which is labor-intensive for farmers and low in harvesting efficiency. In recent years, harvesting machinery has been gradually promoted in large-scale planting areas, but most of these ha...
