Abstract

The invention provides a corn kernel threshing and separating device. The corn kernel threshing and separating device comprises a threshing roller provided with combined threshing components, and eachcombined threshing component comprises thread rod teeth and retractable ball spike teeth; matched threshing concave plates are arranged below the threshing roller and installed on a rack, and the threshing concave plates comprise the upper fixed punched concave plate and the lower movable punched concave plate matched with the upper fixed punched concave plate. Through the threshing components with the retractable ball spike teeth, the threshing effect is enhanced, and the kernel damage is reduced; besides, through the threshing concave plates with the mesh size adjustable, continuous stepless regulation of the concave plate mesh size is realized, the adaptability of a corn kernel direct harvesting machine is enhanced, the kernel damage rate is further reduced, the threshing performance and the screening performance are improved, and thus direct harvesting of corn kernels at different moisture contents is met; meanwhile, the effect of harvesting rice and wheat crops at the same time can be achieved, and the use performances of a combine harvester is improved.

Description

technical field [0001] The invention relates to the field of corn grain harvesting, and specifically designs a corn grain threshing and separation device, which is used to adapt to corn grain direct harvesting machines with different moisture contents, and can perform stretching and stretching of threshing elements and continuous adjustment of the size of threshing concave plate sieve holes. Background technique [0002] At present, the direct harvesting of corn kernels has become the development direction of corn mechanized harvesting in my country. However, due to the limitation of farming time, most of the corn in my country has a high moisture content when harvested, which puts forward higher requirements for corn kernel threshing and separation devices. [0003] Chinese patent CN107535194A discloses "a single longitudinal axial flow rigid-flexible coupling corn threshing device", which further reduces the breakage rate of corn kernels, and improves the cleaning rate by i...
