Embodiment Construction
[0026] Such as Figure 1-7 As shown, a portable mountain grain harvester includes a straw threshing device 1 , a chaff separation and collection device 2 is arranged below the hay threshing device 1 , and the chaff separation collection device 2 is installed on a walking device 3 .
[0027] The described threshing device 1 includes an arc-shaped cover 11 with a front opening, and an upper threshing wheel 12 and a lower threshing wheel 13 are installed side by side up and down in the arc-shaped cover 11, and the upper threshing wheel 12 is in the front and rear positions. Relatively lower threshing wheel 13 moves forward a certain distance, and the front side of upper and lower threshing wheels has a part to stretch out outside the arc cover 11 to carry out the operation of pulling out grain.
[0028] The upper and lower threshing wheels 12, 13 are multi-edge wheels, each edge of the multi-edge wheel is provided with a row of threshing teeth 121 or 131 arranged at intervals, an...

The invention discloses a portable harvester for grains in mountainous regions. The harvester comprises a seedling pulling and threshing device; a grain screenings separating and collecting device isarranged under the seedling pulling and threshing device; the grain screenings separating and collecting device is installed on a traveling device; the seedling pulling and threshing device includes an arc-shaped hood with a front opening; an upper threshing roller and a lower threshing roller are installed in a vertical direction side by side in the arc-shaped hood, and the upper threshing rollermoves forward for a certain distance relative to the lower threshing roller in front-rear position; the front side of the upper threshing roller and the front side of the lower threshing roller partially extend out of the arc-shaped hood so as to perform seedling pulling operation; two sides of the upper threshing roller and two sides of the lower threshing roller are movably connected with the arc-shaped hood through rotating shafts; the rotating shafts at the same side of the upper threshing roller and the lower threshing roller extend out of the outer wall of the arc-shaped hood and are each connected with a driven gear; the driven gears are directly or through a transmission gear connected with a drive gear; and the drive gear is driven by a threshing roller motor. The harvester for the grains in the mountainous regions designed by the invention has a small equipment size, can realize modular disassembly and assembly transportation, and is especially suitable for harvesting the grains in the mountain regions.
Description
technical field [0001] The invention relates to a mountain agricultural machine, in particular to a portable mountain grain harvester. Background technique [0002] Due to limited geographical conditions, the mountainous fields are small in size and the terrain is very complicated, which makes it impossible for existing large-scale harvesters to work at all. This not only increases the labor intensity of operators, reduces work efficiency, and hinders agricultural mechanization Promotion brings a lot of inconvenience. Contents of the invention [0003] In view of the above problems, the present invention designs a portable mountain grain harvester, which is small in size and can be disassembled and transported in modules, and is especially suitable for harvesting mountain grains. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A portable mountain grain harvester, characterized in that: it includes a straw thr...
