2results 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.

The utility model discloses a semi-feeding type rice thresher, and relates to the technical field of agricultural machinery. The semi-feeding type rice threshing machine comprises a machine body, a threshing cylinder and a feeding plate, the feeding plate is assembled on the upper portion of the machine body, a material guiding plate is assembled on the lower portion of the machine body, the threshing cylinder is installed between the feeding plate and the material guiding plate and is designed in a left-right sectional mode, the left section is a primary threshing cylinder, V-shaped arch teeth are distributed on the surface of the primary threshing cylinder, and the right section is a secondary threshing cylinder. And the right section is a secondary threshing cylinder. In order to overcome the defect that threshing is not thorough due to the fact that a threshing machine mostly adopts a single arch tooth structure for threshing, through the design of a left sectional type threshing roller and a right sectional type threshing roller, the V-shaped arch teeth on the left side can be rapidly inserted into the connecting position of rice and rice straw through sharp cutting edges, primary efficient threshing is achieved, residual grains are loosely connected with rice ears after primary threshing, and the threshing effect is good. The U-shaped arch teeth can be attached to rice ears, residual rice is gently and accurately stripped, excessive impact on grains is avoided, threshing cleanliness is improved, grain waste is reduced, and meanwhile straw treatment cost is reduced.
