Embodiment Construction
[0015] During operation, the grain divider (14) at the front end first separates the crops into ridges, and then stirs (16) the front end of the threshing drum on the upper threshing drum (18), and the threshing drum on the lower threshing drum (10). Stir the front end (13) to feed the ears of the crops into the feed port (33), and with the support of the "a" shaped grass support board (29), the combing produced by the upper and lower rollers against each other (11) , strike for threshing, and after preliminary screening by the concave plate sieve (9), the airflow generated by the grain suction fan is transported to the driver's cab by the stirring (8), the lifter (7), and the grain delivery pipe of the lifter (22). The cleaning mechanism at the end cleans again, and finally enters the warehouse. The cleaned crop stems are cut by the cutter (4), pulled out by the pulling wheel (5) and the grass pressing spring (28) and the grass pulling belt (26) mounted on the pulling wheel, ...

The invention relates to a seedling dividing thresher and a dust sucking device of a stem-preserving type (semi-feeding) rice-wheat combine harvester. The seedling dividing thresher comprises a seedling divider, a bracket, an upper packing auger, a lower packing auger, a bearing, a grain screw conveyer, a dispersing machine, a chain wheel, a drive chain, an iron sheet outer cover, and an a-shaped straw supporting plate, wherein the upper packing auger and the lower packing auger are arranged in parallel and respectively provided with a screw on a front end surface and an arch-shaped tooth on a rear end surface. In the dust sucking device, a dust sucking cavity in the shape of a cylinder or a cuboid is arranged on the rear upper end of an integral cutting table and provided with a narrow and long air suction opening facing forward hyponastically, the upper end of the rear side of the dust sucking cavity is provided with an air suction channel, the air suction channel is communicated by the air suction opening and an air suction cavity at the two ends of the air suction channel and is installed in parallel with the air suction cavity, the middle of the air suction channel is communicated with an air suction pipe, and the rear end of the air suction pipe is provided with an air blower used for sending air flow to the rear end of the whole machine. The invention realizes threshing before mowing by virtue of the tension of crop roots towards ground and can save complex and faultful straw conveying and clamping mechanism, thereby reducing the load, the dead weight and the manufacture cost of the harvester, and moreover, the dust suction device can reduce pollution and improve production efficiency.
Description
technical field [0001] The patent of the present invention relates to a threshing device and a dust-absorbing device of a straw-protecting (semi-feeding) rice-wheat combine harvester. Background technique [0002] Most of the existing stalk-protecting (semi-feeding) rice-wheat combine harvesters harvest first and then thresh, and have complicated and troublesome conveying and clamping mechanisms. The disadvantages are: a lot of extra power consumption, many faults, complex structure, high cost, limited cutting width, etc., and the dust on the crop stems is flying due to sowing, harvesting, and transportation during operation, which not only endangers the health of operators , affect the operator's line of sight, consume the energy of the operator, but also pollute the appearance of the machine, increase the degree of wear of the machine parts, and reduce the service life of the machine. [0003] In order to overcome the shortcomings and deficiencies of the existing harveste...
