A cutting knife driving mechanism 5 is arranged below the other end of the gap bridge 12, a movable knife 6 is arranged at the front edge of the bottom of the cutting knife driving mechanism 5, the movable knife 6 and the bottom of the cutting knife driving mechanism 5 are installed in a matched mode, a pull rod 3 is arranged at one end of the movable knife 6, one end of the pull rod 3 is fixedly connected with one end of the movable knife 6, the pull rod 3 drives the movable knife 6 to do reciprocating motion, rapid cutting of rice is achieved, a toothed shaft 16 is arranged on the outer wall of one end of the cutting knife driving mechanism 5, one end of the toothed shaft 16 is movably connected with the pull rod 3 at one end of the movable knife 6 through a connecting piece, a conical gear is arranged at the other end of the toothed shaft 16, a feed port 30 is arranged near one end of the inside of the cutting knife driving mechanism 5, and a gap bridge roller 31 is arranged on the back face of the feed port 30.

Two ends above the cutting knife driving mechanism 5 are symmetrically provided with reel wheel frames 8, one end of each reel wheel frame 8 is matched and installed with the cutting knife driving mechanism 5 through a connecting shaft, a hydraulic cylinder is arranged between the lower part of the center of each reel wheel frame 8 and the cutting knife driving mechanism 5, an auger 9 and a reel wheel 4 are arranged inside the cutting knife driving mechanism 5, a chain is arranged between the reel wheel 4 and a driving mechanism 22, two ends of the auger 9 are matched and installed with the cutting knife driving mechanism 5, two ends of the reel wheel 4 are matched and installed with the other end of the reel wheel frame 8, and the reel wheel 4 can convey rice to the auger 9 inside the cutting knife driving mechanism 5.

The harvesting process of the small multifunctional combine harvester comprises the following steps: the driving mechanism 22 in the combine harvester body 1 drives the cutting knife driving mechanism 5 to the state that the rice is close to the root, the reel 4 on the cutting knife driving mechanism 5 rotates to press down the rice, the rice is pressed down to the bottom of the cutting knife driving mechanism 5, meanwhile, the pull rod 3 indirectly drives the movable knife 6 to do reciprocating motion, the movable knife 6 cuts off the pressed rice, the gear shaft drives the auger to rotate, the auger conveys the cut wheat to the feed inlet 30, the straw roller 11 at the back of the feed inlet 30 conveys the received wheat to the gap bridge chain in the gap bridge 12 at one end of the gap bridge 12 to convey the cut rice to the other end from one end of the cutting knife driving mechanism at a constant speed.

The rice enters the separating roller 17 to be threshed to separate the rice from the straws, the separated seeds fall into the bearing net 13 under the action of gravity, the straws are sent into the rice grain groove 25 under the action of the threshing roller 17, and the straws entering the rice grain groove 25 are bundled by the bundling rack 23 to be discharged in bundles.

The seed that holds in the net 13 falls to shale shaker 19 and carries out preliminary vibration screening, with partial weeds and seed separation in the seed, the seed after the separation enters into drying cabinet 27 and carries out the drying, heating wire 20 produces the heat in the drying process, fan mechanism 21 of heating wire 20 below is continuous lets in the warm braw to the inside of drying cabinet 27, the seed after the stoving enters into the mechanism 18 that sieves under the transport of carrying auger 14, sieve through the one-level on the mechanism 18 that sieves, the second grade sieves, the tertiary sieve sieves material step by step, divide into three kinds of seeds of variation in size with the seed.

Pressure sensor on the automatic charging device couple of crops weighs the collection bag, when pressure sensor weighed the material in the collection bag and reached preset weight, pressure sensor signals and seals the discharge gate, drive unit drives the collection bag that fills with the material and leaves, fixed a position sensor on the track of feed inlet below simultaneously, collude the relevant position when detecting second cover bag and prepare the back to, drive arrangement stop drive, the discharge gate is opened, reach again behind the predicted weight, repeat above-mentioned process.

This combine body 1 can carry out the multistage screening again after the edulcoration is dried to cereal that reaps the in-process convenience, sieves cereal evenly, the later stage process that significantly reduces.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
