Embodiment:

Double-boat type reaper-thresher for rice of the present invention comprises running gear, cutter sweep, threshing collecting device.

boat form kickboard

20,21, and arrange with road wheel 17,18 one-tenth vertical linears respectively, be separately installed with

reference column

backstay

divider

37,38, last cutter 39, following knife edge 40, arc feed well 41.The collar 43, fulcrum 44, the tail collar 45, driver 46 are installed on the cutting arm 42 driving rod 47, spring 48, pogo barrel 49, bearing 50, bearing block 51, gathering sill 52, support 53 are arranged, be installed on the side plate 58, bearing 54, bearing block 55 are installed on the fulcrum 44.

boat form kickboard

After people's controlled clutch driving lever 77 separates clutch 8, ato unit 1, the loosen the clutch driving lever 77 again, clutch 8 engagements, engine 1 drives 5 rotations of gearbox power shaft by shaft coupling 3, thereby makes gearbox 2 speed changes transmission power, and the sprocket wheel 9 on the output shaft 6 of gearbox 2 rotates by the sprocket wheel 14 that chain 12 drives on the walking axle 13, thereby ground-engaging wheel 17,18 rotations, complete machine is advanced forward.Because double-

boat type kickboard

20,21 arranges that with road wheel 17,18 one-tenth vertical linears complete machine can run in the guide paddy rice seedling line space ground, not spreading rice stub and root system respectively.

Belt wheel 11 on the output shaft 6 of gearbox 2 drives rice-pulling shaft 27 by belt 35 and belt wheel 28 and rotates, rice-pulling shaft 27 drives gripper 34 synchronous rotations by

backstay

31,32,33 can bring spike of rice together, delivers to charging aperture 57 along arc feed well 41 after cutter on frame 4 front ends 39 are sheared.When 65 rotations of the belt wheel on the threshing axle 60, clapboard 68 contact bearings 50 on the belt wheel 65 and impeller-hub bearing 51 and driving rod 47 move laterally along gathering sill 52, thereby ordering about the collar 43 and cutting arm 42 outwards moves around fulcrum 44, cutting arm 42 orders about cutter 39 by the tail collar 45 and moves, and shears the rice bar that enters down in knife edge 40 grooves.Disengage with bearing 50 when belt wheel 65 continues rotation clapboards 68, under spring 48 tension force effects, driving rod 47 returns also drive cutting arm 42 and move inward, and cutting arm 42 orders about 39 returns earnestly by the tail collar 45, promptly realizes moving back and forth the work of cutting.

Belt wheel 10 on the output shaft 6 of gearbox 2 drives 60 rotations of threshing axle by belt pulley 66, regulating wheel 67, belt wheel 65, the hemi-closure space that cylinder 63 that connects firmly on the threshing axle 60 and spirality broach 64 are formed the spike of rice precession top cover 56 at charging aperture 57 places, arc orifice plate 69, side plate 58,59 revolves and stirs, and progressively the rotation of rice bar is dished out outside the machine by side plate 59 tops.The grain that stirs falls through the arc orifice plate, drops into collecting box 74,75 by gradation plate 70, rubber 71, so promptly advances, brings together spike of rice, cutting, transmission, threshing, throwing bar for intact one, collects the working procedure of grain.And not spreading damages the fringe stake can hold ratoon rice.Regulate the reference column 22 upper end spiral ducts 25 on the

boat form kickboard

20,21, can adjust the angle of inclination of complete machine front portion, be convenient to cut corresponding height and spike of rice.
