AI Technical Summary
Traditional rice harvesters are prone to excessive crushing and improper cutting height damage to rice stubble, reducing the germination rate and yield of ratooning rice. At the same time, debris is scattered randomly during threshing and transportation, clogging soil pores and affecting soil aeration and water retention.
A rice harvester suitable for storing ratooning rice was designed, comprising a cutting component, a conveying pipe, a threshing component, and a debris collection component. The cutting component protects the rice stubble with a semi-enclosed arc-shaped cover and a hydraulic rod. The threshing component uses blunt-toothed crushing blades and guide convex strips to separate the rice grains from the debris. The debris collection component collects the debris by negative pressure adsorption.
It effectively protects rice stubble, improves the germination rate and yield of ratooned rice, reduces soil compaction, ensures soil aeration and water retention, reduces debris coverage, and optimizes the rice field growing environment.
