Crop harvester

Abstract

A crop harvester comprises a machine frame, a shovel blade located at the front end of the machine frame, and a vibrating screen located on the rear middle portion of the machine frame, wherein vertical rotary rollers are arranged at the two sides of the front end of the machine frame respectively, gaps are reserved between the rotary rollers and the machine frame, and the two rotary rollers are connected with a power shaft; at least one pair of annular male and female sealing parts is arranged in each rotary roller and located in a gap between a bearing seat and a bearing seat shaft, the outer sides of the male and female sealing parts are in interference fit with the bearing seat, and the bearing seat shaft is arranged in center holes of the male and female sealing parts; a rear ridge roller is arranged below the rear portion of the machine frame and hinged to the machine frame. The harvester is suitable for various soil types including sandy soil, sandy loam and medium clay soil; by the adoption of a three-wheel vibration system, crop and soil separating effect is good, yield rate is higher than 99%, and damage rate is lower than 1%; through the design of the rear ridge roller and a collection baffle, damage to crops is reduced, and crops are gathered after falling onto the ground and are easy to harvest; weed blocking is avoided, soil leakage is quick, and 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 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 harvesting...
