Description

The walking rice-wheat thresher

The utility model relates to a kind of crops thresher machine, particularly a kind of walking rice-wheat thresher.

The crops thresher machine mainly contains two types at present: a class is that power set and sheller unit are separated; during use the two is lifted; after shouldering selected fixed-site Installation and Debugging; the crops of harvesting are transported in the ground again that sheller unit is other to carry out threshing; mainly there is following defective in this sheller unit; the Installation and Debugging trouble; labour intensity is big; recruitment is many; the balloonflower root husk is the time-consuming worker employed in a plant nursery in field also; the volume of thresher is bigger; it is constant to turn round; another kind of is the full automatic combine grain header; power set and sheller unit are connected as a single entity; can be with harvesting; threshing and balloonflower root husk are also once finished in the field, this type thresher complex structure; power requires big; cost an arm and a leg; volume is big, is difficult to adapt to the knob operation.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of power and sheller unit to be connected as a single entity, and is simple in structure, easy to maintenance, power is little, price is low, saving of work and time, can adapt to the walking rice wheat tax grain machine of hills, mountain area operation.The utility model does not need interim Installation and Debugging when using, the crops that need not carry the band fringe of harvesting, and directly in the operation limit threshing of cropland the inside, the field is evenly gone back with the straw husk in the limit, the threshing performance height, the paddy bar separates thoroughly.

The purpose of this utility model realizes by following technical proposals:

Design a wheeled framing holder, framing holder one end is the push-and-pull handle, framing holder top by bolt respectively with power set and sheller unit Joint, the belt pulley of power set and sheller unit is connected by belt.

Said sheller unit is by loam cake, the cylinder of barbed nail, screen cloth, pneumatic separation device and frame constitute, on the frame between screen cloth and loam cake, be provided with the knife rest group, on each knife rest group several blades are housed, blade one end is fixed on the knife rest, the other end stretches out as cantilever, in the longitudinal direction perpendicular to the cylinder axis line, the blade cross section is a triangle, the adjacent knife blades gap guarantees that the cylinder spike-tooth can freely pass through, cylinder one end is provided with deflecting blade, its outer side frame is provided with the feed hopper bolt, link to each other with two hooks that are provided with or the collar of feed hopper, cover on the feed hopper end far away and be provided with careless shell outlet, the cylinder below is provided with metallic sieve, metallic sieve has a funnel affixed with frame, be used to collect the grain and the husk that fall from screen cloth, one opening is arranged at the funnel bottom, opening part is connected with a pneumatic separation device, pneumatic separation device is made of spiral case and flabellum, the belt pulley of flabellum axle head links to each other with the sheller unit belt pulley, spiral case is split into the husk outlet along air outlet tangent line extension, the opening part of aiming at funnel on spiral case is provided with the grain outlet, when grain and husk when the funnel opening part falls, the wind that flabellum blows out in the spiral case blows out the husk outlet with lighter husk, and heavier grain falls into the grain outlet, and the grain outlet is provided with a plate, so that change the pocket of collecting grain.

During use, with the utility model with manpower or animal power push-and-pull in the cropland, the threshing while walking, the crops of need threshing is sent into from feeding funnel, be involved in through cylinder upper deflecting blade, under spike-tooth and blade intense attrition, grain is separated from the paddy bar, and long simultaneously paddy bar shreds through blade, and grain and part husk fall by screen cloth, the shell grass is told also field with the part husk from the careless shell outlet that covers, because the vibration when power set and walking, grass separates more thorough with grain, separate through pneumatic separation device when grain falls with husk, husk evenly goes back to the field from the husk outlet, and grain then enters collection container from the grain outlet.

From above-mentioned situation as can be known; the purpose of this utility model can realize; because power and sheller unit all are fixed on the framing holder; the two assembly relation is constant; save interim assembling and setting; the framing holder downside is provided with road wheel; guarantee that its operation is convenient; be easier to move in the field, crops; in addition little, in light weight, the flexible operation of volume convenient, save and carry operation back and forth, save labour and time; it can evenly go back the field with the husk of straw uniformly simultaneously, is a kind of comparatively desirable thresher machine.
