5) when turning over grain component close to tail component, tail gemmule pawl insertion ratchet II teeth groove, tail gemmule pawl is while promote spine Wheel II rotates one side around hinge II swings, until tail gemmule pawl departs from ratchet II opposite side；In the mistake of ratchet II rotations Check ratchet II and ratchet II is in disengaged condition in journey, and around check ratchet II pivots, when ratchet II stops operating Check ratchet II reinserts ratchet II teeth groove, prevents ratchet II opposite directions from rotating；Ratchet II rotations pass through ratchet II axle bands Dynamic drive bevel gear II rotations, front-wheel II rotations are driven by dynamic bevel gear II, then tail component is towards one section of M directions stepping Distance；Due to front-wheel II direction of the direct of travel deviation away from nose assembly, although there is remote trend, by head group Part is held by flat belt can not be very away from nose assembly, the result is that so that flat belt keeps larger tensile force；Turn over Grain component also can be with moving under the tensile force effect of flat belt towards step direction, drive pulley, the first bend wheel group, spiral shell Revolve component, the second bend wheel group and negative pulley wheel still it is horizontally arranged point-blank；

6) tail side impact head touching inclined-plane II, Shifting rack switching position, tail side impact head are switched to upper, head side impact by bottom Head is switched to bottom by upper, while upper plate stirs one section that pilled-in selvedge is between three footpaths wheel and the second bend wheel group down, Pilled-in selvedge is switched to by being wrapped in path section and is wrapped in big footpath section, and rotating diameter becomes big footpath section diameter D3, turns over the motion of grain component Speed, the direction of motion, the movement velocity of screw assembly and the same step 2 of operation principle；Tail gemmule pawl streaks from ratchet II Free state, ratchet II can't be driven to rotate, tail gemmule pawl also will not be by the resistance from ratchet II；

7) step 2) is repeated continuously to 6), then turning over grain component under the drive of nose assembly and tail component along fold-line-shaped road Footpath is moved, and the screw assembly for not stopping rotation does not stop then to stir the grain on ground.

Beneficial effects of the present invention：Automatic turning grain is completed by automated machine, manpower is saved, efficiency high, improves grain Efficiency is dried, reduces the moisture of grain, avoids food storage from getting up mouldy, infested evil, avoids because grain quality influences people Health.
