A New Grain Harvesting System for Single-Pass Grain Harvest, Biomass Collection, Crop Residue Sizing, and Grain Segregation

Abstract: A cereal grain harvesting system is introduced that combines existing technologies in a unique way to improve cereal grain harvest performance, increase profitability, and efficiently collect biomass. The harvesting system is comprised of three machines: one to reap grain, harvest biomass, and size crop residue for no-till seeding; a second to thresh and winnow the grain; and a third to separate the grain by quality for added value. This study describes the new harvesting system and the development of one of t… Show more

“…Wilkins et al [13] conducted a field test using a trial preharvest threshing device to examine the influence of operational parameters, such as the forward velocity, on harvesting losses. In [14], Siemens et al optimized the design of the structural variables of threshing combs without altering the overall structure of the preharvest threshing device, which led to a measurable reduction in harvesting losses. Tang et al [15] conducted bench tests on a preharvest threshing device, utilizing a high-speed imaging device to observe and investigate the process and mechanism of rice grain throwing and its distribution characteristics.…”

“…This method makes it possible to increase the productivity of combine harvesters many times with a significant reduction in their energy and metal consumption. Grain crops and rice harvesting by combing plants at the root is being carried out by scientists in many countries around the world [1][2][3][4][5]. But to increase the reliability of technological process of harvesting crops, it is necessary to improve the reliability of the working parts of the cutterbar of the combine harvester.…”

“…Through the dynamic analysis of the pickup, the mathematical model of the peanut harvester pickup is designed according to the torque and feeding quantity of the power input shaft of the peanut harvester pickup. The relationship between the feeding quantity of the combine harvester and the loss rate of the harvesting process was analysed to establish the mathematical model of them (Siemens and Hulick, 2008). However, there are many factors that affect the change of feeding quantity, and the actual working environment is complicate, which lead to a large measurement error.…”
