Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a thresher with improved threshing rate. Background Art
[0002] Corn thresher is a small agricultural machine widely used in agricultural production and plays an important role in the agricultural field. It is a specially designed device that can efficiently separate corn kernels from corn stalks, providing great convenience for farmers to harvest corn.
[0003] Under current technological conditions, most corn threshers fail to fully consider the varying sizes of corn cobs encountered during actual operation during their design and use. Problems arise when threshing cobs of varying sizes. Due to a lack of targeted design, smaller cobs easily leak through the gap between the thresher's drum and concave plate. These leaking small cobs are not fully threshed, resulting in a large amount of corn kernels remaining on the cobs. This not only wastes food but also requires additional manpower and time to subsequently process these unthreshed cobs. This situation seriously affects the overall threshing efficiency of the corn thresher, failing to meet the demands of efficient agricultural production. This makes the threshing process, which could normally be completed quickly, become tedious, increasing the cost and time of agricultural production and causing unnecessary trouble for farmers.
