Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0016] Referring to the accompanying drawings, the rice-wheat combine harvester separation device among the figure includes the slag outlet 12 arranged on the top of the housing 2 and the concentrated material outlet 5 at the lower end, and the housing 2 wall opposite to the concentrated material outlet 5. A separator 1 composed of a coarse material inlet 4 and a dust fan 3 arranged in the middle and upper part of the housing 2, wherein: the coarse material inlet 4 of the housing 2 is docked with the discharge port 7 on the threshing box 13; the dust fan 3 is unilaterally connected to the side wall of the shell 2 adjacent to the coarse material inlet 4 through a bearing, and the shaft of the dust raising fan 3 is directly connected with the power output shaft 10 sprocket or belt arranged on the threshing box 13 .
[0017] In the above structure: a bypass exha...

The invention relates to agricultural machinery, in particular to a separation unit for a rice-wheat combine harvester. The separation unit for a rice-wheat combine harvester comprises a separator which is composed of a discharging port arranged at the top end of a casing, a fine fodder outlet arranged at the bottom end of the casing, a coarse fodder inlet arranged on the casing wall opposite to the fine fodder outlet, and a dirt raising fan arranged on the middle upper part of the casing, wherein the coarse fodder inlet of the casing is butted with a fodder discharging port on a threshing box; the dirt raising fan is connected to the side wall of the casing adjacent to the coarse fodder inlet through the singe side of a bearing, and a shaft of the dirt raising fan is directly connected with a power-output shaft sprocket wheel or belt on the threshing box. Due to the structure, the separation unit for a rice-wheat combine harvester has the advantages of high work efficiency and less loss of kinetic energy; and the separation unit can regulate amount of wind and variation of speed as required, and can also reduce use cost.
Description
technical field [0001] The invention relates to agricultural machinery, in particular to a rice-wheat combine harvester separation device capable of improving working efficiency. Background technique [0002] With the development of social productivity, miniature agricultural machinery is gradually popularized, and rice and wheat combine harvesters are especially popular in the hilly areas of our country. However, during the use of the rice and wheat combine harvester, the stalks in the threshing box are in a moving state and are easily cut off by the detachment teeth, resulting in short grains entering the grain container, thereby increasing the labor of farmers. In order to reduce the labor of farmers, the rice and wheat combine harvesters currently on the market are connected to a separator through a discharge pipe at the outlet of the escape box, and the short grains are separated from the grains or wheat grains through the separator, so that certain Reduced the workloa...
