Problems solved by technology
[0006] Limited by the width of rural roads, the existing "tangential flow + transverse axial flow" threshing and separation device cannot be too long due to the horizontal arrangement, the threshing and separation capacity is limited, the feeding amount is difficult to break through, and the machine's working efficiency is low, which can no longer satisfy modern users. need
In addition, the harvesting of different crops or crops with different degrees of maturity is not enough for the current harvesters.

Embodiment Construction
[0018] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings, but this does not constitute any limitation to the present invention.
[0019] figure 1 and figure 2 A schematic diagram of a grain combine harvester according to one embodiment of the present invention is shown. Such as figure 1 As shown, a vertical axial flow grain combine harvester according to an embodiment of the present invention includes a header assembly 31 to complete support, cutting and feeding of crops. The downstream of the header assembly 31 is provided with a bridge crossing device 32, which completes the conveying of the crops fed from the header assembly 31. A threshing and separating device 36 is provided downstream of the bridge device 32 to complete threshing and separation of the crops transported by the bridge device 32 . An arc plate 44 is arranged on the right side of the straw outlet at the rear of the t...

The invention discloses a grain combined harvester and a threshing and separating device thereof. The threshing and separating device comprises a threshing cylinder, a threshing concave plate, a concave plate fixing beam and a concave plate adjusting device, wherein the threshing concave plate is located at the lower part of the threshing cylinder, and the upper part of the threshing concave plateis provided with a concave plate connecting part; the concave plate fixing beam (26) is provided with a fixing beam connecting part, and the concave plate connecting part and the fixing beam connecting part are matched with each other so that the threshing concave plate (25) can move up and down and be connected with the concave plate fixing beam (26) through the concave plate connecting part andthe fixing beam connecting part; the lower part of the threshing concave plate (25) is connected with the concave plate adjusting device, and the concave plate adjusting device can make the threshingconcave plate (25) move up and down relative to the concave plate fixing beam (26).
Description
technical field [0001] The present invention relates to a grain combine harvester. Background technique [0002] At present, the concentration of land transfer in the country has further intensified, family farms have gradually formed, and it has become a trend to form harvesting teams in the form of agricultural machinery cooperatives. [0003] With the adjustment of the planting structure of the country, the support for crops with high yield per unit area, such as wheat and rice, has been increased, and the planting area has been increased, which has promoted the demand for large-feeding grain harvesting machinery. [0004] In order to ensure good air quality, the state has stepped up strict investigation and punishment on straw burning, and returning straw to the field has become one of the conditions for harvesting. [0005] With the continuous improvement of rural living standards and user knowledge, modern users pay more attention to the comprehensive economic benefit...
