Abstract
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 and a thresher and structurally comprises the seedling divider, a bracket, an upper threshing cylinder, a lower threshing cylinder, 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 threshing cylinder and the lower threshing cylinder 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. By adopting a crop high-low indicator and hydraulic lifting, an optimum height required by threshing can be better ensured to be adjusted effectively. The scheme 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
Patent of the present invention relates to a kind of guarantor's straw formula (half feeding) rice/wheat combine and divides standing grain thrasher and dust exhaust apparatus.
Background technology
Existing guarantor's straw formula (half feeding) rice/wheat combine mostly is and gathers in threshing more earlier, and the conveying clamp mechanism of complicated many events is arranged.Shortcoming is: it is many to consume extra power, fault is many, complex structure, cost height, restriction swath etc., and owing to broadcast grass, harvesting, conveying the dirt ash on the cane of crops is flown upward during operation, both endangered health of operators, influence operating personnel sight line, consumed operating personnel's energy, also polluted the outward appearance of machine simultaneously, increase the machine members degree, reduced the service life of machine.
For the shortcoming and deficiency that overcomes existing grain header, patent of the present invention provides a kind of guarantor's straw formula (half feeding) rice/wheat combine to divide standing grain thrasher and dust exhaust apparatus.
Summary of the invention
It is such that patent of the present invention solves the technical scheme that its technical problem adopts: divide the standing grain thrasher to be made up of nearside divider and thrasher, its structure comprises that nearside divider, support, front end surface are equipped with two threshing cylinders up and down, bearing, the defeated grain that stir rear end surface the parallel installation of bow tooth is housed and stir, throw and raise device, sprocket wheel, driving chain, iron sheet outer cover and " a " shape and hold up careless plate composition.Dust exhaust apparatus is to be that back upper end, vacuum chamber that the vacuum chamber of cylinder or cuboid is fixedly mounted on the whole ceding of Taiwan have the narrow inlet scoop of grow, inlet scoop facing to the place ahead on the lower side, be provided with the air draught road on its rear side by shape, wind inlet by two ends is communicated with the air draught chamber, and with the parallel installation in air draught chamber, middle part, air draught road is communicated with aspiration channel, and the aspiration channel rear end is that blower fan is delivered to the complete machine rear end with air-flow.
During operation, nearside divider foremost becomes the crops on the ridge separately earlier, by up-down roller front end stir hold together with crops fringe portion feeding spout thereafter, hold up in the support of careless plate " a " shape, fight each other relatively by up-down roller, bow stripping fork reason, hit threshing, filter the back through concave grate and raise device, induced-draught fan and will take off the dressing mechanism that seed well is delivered to the driver's cabin rear end with air-flow and clean, put in storage at last by stirring, throwing.The crops cane that is purified is broadcast by broadcasting the standing grain wheel, and cutter cuts is broadcast the turf strip sowing and sent, and grass-removing wheel is emitted on the field in good orderly.The threshing height that crops height indicateing arm and hydraulic lifting more can guarantee to regulate accurately and effectively needs the best is installed.And the dust that flies upward that causes because of harvesting sends vacuum chamber by the air-flow suction that dust absorption fan produces to through aspiration channel, air draught road, wind inlet, grow than the inlet scoop is narrow greatly because of the vacuum chamber inner capacities again, air-flow is evenly distributed, the dust that harvesting is caused all siphons away, deliver to the grain header rear end, make it to reach zero and pollute.The grain header dust exhaust apparatus also can be installed on other type combine.
The beneficial effect of patent of the present invention is: use the crops root pulling force on ground is realized threshing prior to cutting, save the conveying grass-trap mechanism of complicated many events, load, weight and the manufacturing cost of grain header have been reduced, disperse threshing can make ceding of Taiwan swath do not fed quantitative limitation and increase the width of swath, increase work efficiency.Held together to connect really because the crops is stirred before this, reduced the percent of loss of grain, improved the threshing cleanliness, adopt crops height indicateing arm and to the hydraulic lifting of nearside divider can more accurate control to the feed quantity of crops fringe portion.Dust exhaust apparatus can reduce pollution, improves the comfort level of behaviour chamber, has guaranteed health of operators, has prolonged the service life of machine, has improved production efficiency.
