(3) utility model content:
Technical problem to be solved in the utility model, is to provide one and realizes threshing, automatically separates grain, straw, and separates totally, reduces the paddy thresher of waste.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Paddy thresher; comprise hollow casing, be arranged on box house threshing cylinder, be arranged on the outer threshing cylinder power device being connected with threshing cylinder of casing and be arranged on the screen cloth below threshing cylinder; described screen cloth be horizontally set on threshing cylinder under; be connected with and can drive the driving rod of screen cloth along threshing cylinder axially reciprocating in the both sides of screen cloth; this driving rod is connected with screen cloth power set; the side of screen cloth is also provided with the gear being connected with threshing cylinder, on gear, be provided with extend to screen cloth, can stir straw stir piece.Conventionally straw is all to fall screen cloth from the two ends of threshing cylinder, makes the straw at screen cloth two ends a lot, above grain is also constantly fallen, be easy to wrap up in straw, screen cloth, along the axially reciprocating of threshing cylinder, can reduce the accumulation of screen cloth two ends straw, is easy to make grain to pass through screen cloth; And stir piece and can stir straw, the grain that makes to be rolled in straw is shaked out, and stirs in addition piece and can also beat spike of rice, makes grain threshing from spike of rice, reduces the grain of getting rid of in company with straw, and then cuts the waste.
In order to stir more frequently the straw on screen cloth, described gear is multiple, arranges successively, and on gear, be equipped with the described piece that stirs along the side of screen cloth.
In order further to improve the threshing efficiency of the spike of rice on screen cloth, described in stir piece termination be hammer shape structure.
In order to improve the threshing efficiency of grain, on the side of described threshing cylinder, be provided with strip scraping blade along its axis direction.
In such scheme, described scraping blade is 8, is evenly arranged on the side of threshing cylinder.
In order to separate shrivelled kernel grain, described screen cloth below is provided with fan blower, and this fan blower is connected with the side of casing.
In such scheme, the outlet of described fan blower is connected with an ajutage, the outlet of this ajutage be located at screen cloth one end under, and just under the screen cloth other end.
Compared with prior art, screen cloth of the present utility model can move back and forth along the axis direction of threshing cylinder, to reduce the accumulation of straw at screen cloth two ends, and then has reduced the grain being wrapped in straw, makes grain can pass through smoothly screen cloth; And be provided with and stir piece in the side of screen cloth, this stirs piece not only can shake off out by grain from straw, and can beat whole piece and drop to the spike of rice on screen cloth, make the grain threshing on spike of rice, reduce greatly the grain of discharging in company with straw, reduced waste, saved grain.
