1results about How to "Efficient threshing" patented technology

This invention discloses a low-loss, high-efficiency grain threshing device, relating to the field of agricultural machinery and equipment technology. It includes a threshing drum, a concave screen, a forced-feed auger, and a flow guide hood. The concave screen is fitted around the outside of the threshing drum, the forced-feed auger is located at the feed end of the threshing drum, and the flow guide hood is fitted around the forced-feed auger and connected to the front end of the concave screen. The threshing drum is equipped with threshing elements. The threshing rods on the front, middle, and rear of the threshing drum are respectively a first threshing rod group, a second threshing rod group, and a third threshing rod group. The first threshing rod group consists of 3-4 rods per group, the second threshing rod group consists of 4-6 rods per group, and the third threshing rod group consists of 2-3 rods per group. The height of the second and third threshing rods is twice the height of the first threshing rod. The gap between the first and third threshing rods in the same group is greater than the gap between the second threshing rods in the same group. This invention is beneficial for improving threshing efficiency, reducing threshing losses, and achieving high-efficiency grain threshing with low loss.
