Abstract

The invention provides a corn threshing concave plate with adjustable grid intervals. The corn threshing concave plate comprises a fixing mechanism for grid circular steels, grid circular steels, an upper connecting plate, two grid circular steel slide slot plates and a lower connecting plate, wherein the fixing mechanism for grid circular steels comprises a fixing plate and a connecting plate; the upper end of the connecting plate is detachably connected with the upper connecting plate; the upper end of the fixing plate is fixedly connected with the lower end of the connecting plate; a hinge hole is formed at the lower end of the fixing plate and is hinged with the lower connecting plate; the top ends of the grid circular steel slide slot plates are respectively in fixed connection with the two ends of the upper connecting plate; the bottom ends of the grid circular steel slide slot plates are respectively in fixed connection with the two ends of the lower connecting plate; the grid circular steels can slide in the slide slots of the grid circular steel slide slot plates; the fixing mechanism for grid circular steels is started for adjusting the positions of the grid circular steels in the slide slots of the grid circular steel slide slot plates, so that the adjustment for the intervals of the grid circular steels can be realized. The corn threshing concave plate can adjust the intervals of the grid circular steels according to the variety and size of the corn, so that the crashed rate and loss rate of the corn can be reduced and the threshing effect of the corn can be promoted.

Description

technical field [0001] The invention relates to the field of corn grain combine harvester threshing and separation, and specifically designs a threshing concave plate with adjustable grid spacing, which can adjust the spacing of grid round steel according to the size of corn to realize corn threshing with high efficiency and low loss. Background technique [0002] Corn is one of the three major food crops in my country. Traditional corn harvesting mainly adopts the method of segmented harvesting, which has a large workload and is time-consuming and laborious, which cannot meet the situation of large-scale harvesting of corn in my country. The harvesting time of corn grain direct harvesting is short and the labor productivity is high. In recent years, it has attracted more and more attention in China, and it will be the main way of corn harvesting in the future. [0003] One of the key parts of corn grain direct harvesting is the corn threshing concave plate, which affects th...
