Abstract

The utility model relates to a universal grain threshing machine. The universal grain threshing machine is mainly characterized in that the universal grain threshing machine is provided with three drive threshing rollers 1a and two driven threshing rollers 1b; during operation, the drive threshing rollers and the driven threshing rollers rotate reversely so as to realize the purposes of automatic feeding, discharging and fast threshing during the harvest of grains. The universal grain threshing machine is especially suitable for the threshing of corn cobs; no matter how the thickness of the corn cobs change, the engaging of the threshing teeth on the rollers to the corn cobs is unchanged; when the corn cobs are threshed fast and efficiently, the corn cobs can be automatically extruded continuously; the universal grain threshing machine can replace a wheat scourer so as to be used for the threshing of the rice or the wheat, and wheat straws and straws are not easily rolled into the universal grain threshing machine; because of the winnowing of a windmill, the threshed grains or kernels are cleaner, which is convenient to dry; the utility model brings convenience to the harvest of the grains in countries.

Description

A kind of universal grain thresher

One, technical field

The utility model belongs to agricultural machinery, particularly a kind of grain thresher.

Two, background technology

At present, what the threshing after results of cereal crops paddy, wheat and corn was all adopted is special-purpose thresher, and for example husker sheller can only be used for the threshing of corn ear, and can not be used for the threshing of paddy and wheat; And the thresher of paddy or wheat (being commonly called as threshing machine or wheat scourers) can not be used for the threshing of corn ear; Be exactly the threshing machine of prior art, indrawn straw is more in the rice threshing process, though also can be used as the wheat threshing, easily the wheat head is fractureed, and the seed that wraps in the shell is difficult for stripping out, and the threshing effect is not good enough.Above-mentioned condition causes the inconvenience of peasant household when grain harvest, and uneconomical practicality.

Three, summary of the invention

Goal of the invention of the present utility model is the defective that exists at existing grain thresher, manufactures and designs a kind ofly can be used for corn rod threshing, can be used for paddy or wheat threshing again, and the universal grain thresher of threshing rapidly and efficiently.

Realize goal of the invention of the present utility model by the following technical solutions.

A kind of universal grain thresher, include electromotor, belt pulley, power transmission shaft, bearing, threshing tooth, box body and under-chassis frame, it is characterized in that: same horizontal line is provided with three initiatively threshing discaling rolls, they are assemblied in respectively on separately the final drive shaft, and be bearing on the box body by bearing, stretch out outside the box body at the final drive shaft two ends, and mutually same end the axle on assemble drive sprocket respectively, be with first drive sprocket the axle on assemble belt pulley; On the other end axle of first final drive shaft, assemble driving gear; At three initiatively above the threshing discaling rolls on the same horizontal line, be arranged with in parallel two with the driven threshing discaling rolls of threshing discaling roll dislocation arrangement initiatively, they be assemblied in respectively separately from power transmission shaft, and be bearing on the box body by bearing; Corresponding to the final drive shaft that is equipped with driving gear, mutually same end be respectively fitted with driven sprocket from power transmission shaft, first driven sprocket the axle on be equipped with the driven gear that is meshed with driving gear; On three drive sprockets and two driven sprockets, be with initiatively chain and driven chain respectively; Electromotor is arranged on under-chassis frame bottom, it with belt pulley between link to each other with the V-belt.Its feature also is to be provided with the uniform flat threshing tooth of at least 3 row axioversions on each active threshing discaling roll and driven threshing discaling roll; Back upper end at box body is provided with feed hopper, and front end is provided with closable corncob cellulose outlet; The upper end is provided with the outlet of straw, wheat husk before the under-chassis frame, and trailing flank is provided with the seed outlet, and inside is provided with the division board that separates seed and impurity, and is provided with the windmill that is connected as a single entity with division board in the posterior end, links to each other with the V-belt between windmill and the electromotor.

The grain thresher of the utility model structure, be specially adapted to the threshing of corn ear, owing to adopted the reverse rotation of a plurality of driving and driven threshing discaling roll to extrude, make the corn ear abdomen back of the body all be subjected to the active force of threshing tooth, no matter the thickness of corn ear changes, the threshing tooth is all constant to the engagement force of corn ear, can reach the purpose that makes corn ear threshing rapidly and efficiently, also constantly corncob cellulose is extruded automatically; Its also alternative threshing machine or wheat scourers; be used for the threshing of paddy or wheat; because what the threshing discaling roll adopted is the flat threshing tooth of the uniform arrangement of axioversion; in paddy, wheat threshing course; straw, straw are difficult for being involved in wherein; there is windmill to cooperate selection by winnowing in addition, makes grain or the wheat deviate from comparatively pure, be convenient to cool the solarization.The universal grain thresher of the utility model structure brings great convenience for the rural area grain harvest, and very economical practicality has vast market prospect.
