Abstract
A bidirectionally rotational roller type corn thresher is a positive-reverse rotation device, and when a center rotor is driven to rotate to thresh corn, a cylindrical screen around the center rotor is also driven to rotate reversely. Original spikes on the rotor are modified into 'U'-shaped blades. The surrounding cylindrical screen is capable of screening, threshing and guiding, so that breakage rate is lowered for the corn thresher. Threshing rate of corn in threshing is increased.
Description
Affiliated technical field
The present invention relates to a kind of by electromotor or explosive motor as power; The rotor of driving husker sheller also drives shaft screen reverse rotation on every side when rotating; Accomplishing the about threshing to corn ear by rotor and shaft screen acting in conjunction, is a kind of corn threshing novel mechanical equipment.
Background technology
At present known general husker sheller is electromotor or the rotation of internal combustion engine drives center roller, and spike-tooth is arranged on the rotor, on the corn ear corn particle in the bump that receives spike-tooth on the rotor, spreading, swat and come off; But in threshing course; What use is spike-tooth rather than bolt cutter, and threshing chamber does not have certain extendable room, causes the corn particle percentage of damage high; Particle is from the slit of corn ear, to pass during the rotation of internal layer rotor, causes and cleans shortcomings such as unclean threshing performance is low.
Summary of the invention
In order more effectively corn ear to be implemented threshing; The present invention is provided with the sheller unit of a kind of internal layer rotor and the both forward and reverse directions rotation simultaneously of outer shaft screen; Changed the motionless shortcoming of traditional notch board shaft screen, made the notch board shaft screen have three kinds of functions: 1, screening, 2, guiding, 3, threshing.
The technical scheme that the invention technical solution problem is taked is: husker sheller mainly contains feed arrangement, rotor and rotor assembly, notch board shaft screen, cylinder (machine shell), five part formations of frame; Whole sheller unit becomes (30 °-45 °) elevation angle with horizontal plane; Charging aperture is arranged on whole threshing part upper end; Between rotor and the notch board shaft screen, corn ear gets into threshing chamber thus, and promptly notch board shaft screen radius deducts the width that the difference of rotor radius is exactly the threshing chamber space; Electromotor or explosive motor are arranged on thresher fuselage lower end, drive the center rotor rotation through V-belt, belt wheel.Around shaft screen, be provided with gear ring, through the reverse rotation of gear driven shaft screen, respectively there are some balls at the two ends between shaft screen skin and cylinder (machine shell), keep shaft screen relative stability when rotating, and promptly rotate at grade.The rotor separated into two parts, the forward part upper end is near charging aperture, and an end is provided with tapered screw feeder, progressively corn ear is stirred into threshing chamber; The rotor rear section is bolt knife bar and the bolt cutter that threshing is used, and accounts for the 80%-90% of whole rotor, and the bolt cutter is arranged to " U " font, and two ends are enclosed within on the bolt knife bar; It is short elongated gradually that this bolt cutter handle of a knife is crossed cause from charging aperture, and when rotor high-speed rotated, because action of centrifugal force, corn particle came off from corn ear because receiving the bump of bolt cutter; The width of threshing chamber is about 1.5 corn ear in the upper end of charging aperture, and discharging opening is about a corn ear, guarantees that corncob cellulose freely overflows, and the bolt knife bar is between (8-24) root; General about 5 centimeters bolt cuttves, the bolt cutter is some on each bolt knife bar, is provided with according to the clean level of threshing, and the notch board shaft screen is a cylinder shape; Screen cloth is made up of horizontal glazing bar and vertical lattice silk, and glazing bar is not horizontal straight line, but horizontal helix, shaft screen is like the nut of an amplification; Several glazing bar positions of relative displacement, front and back, shaft screen plays the effect that corn ear is pushed ahead when rotated, and recessed partial width of the glazing bar of notch board shaft screen is about (1-3) centimetre, when high-speed reverse is rotated; Not only have the effect of pushing ahead, but also possess flailing action, directly from sieve aperture, flown out by the action of centrifugal force particle, corn ear does not stop to roll just as many balls in threshing chamber; About two sides is all in threshing, and discharging opening overflows cylinder to corncob cellulose from the lower end, and notch board shaft screen skin is cylinder (a machine shell); Corn particle flies out from sieve aperture, impinges upon cylinder (machine shell) and goes up free-falling, then; After collecting, dry, putting in order, particle outlet is discharged from the below, and threshing is so far accomplished.
The rotating speed of central cylinder adds the rotating speed of notch board shaft screen, and is suitable with the rotating speed of former husker sheller, and per minute 1000 changes.
The beneficial effect of the invention is: 1, from epitrochanterian spike-tooth of past, become " U " word bolt cutter on the bolt knife bar, reduced the percentage of damage of corn particle, guarantee the complete of corncob cellulose better; 2, threshing speed has not only been accelerated in outer rotaring tube sieve reverse rotation simultaneously, and corn particle cleans to become and be easy to, and has improved the threshing performance of corn.

Embodiment
In Fig. 1, corn ear gets into from feed arrangement 2, and under the acting in conjunction through rotor and the positive and negative two-way rotation of shaft screen, in the process of clashing into each other, corn particle comes off from corn ear, from sieve aperture, separates, and corncob cellulose overflows from the lower end of cylinder 1.
Claims (2)
1. two-way rotary drum-type husker sheller, it is characterized in that: it is a kind of two-way whirligig, also drives on every side shaft screen when rotor rotation is carried out threshing and makes backward rotation driving.
2. two-way rotary drum-type husker sheller according to claim 1; It is characterized in that: when corn ear gets into threshing chamber; Corn particle on " U " word bolt cutter and the shaft screen in the two-way rotation of glazing bar under the common bump, comes off from corn ear on rotor gradually, separates from sieve aperture; Respectively there are some balls at two ends between shaft screen skin and cylinder, keep shaft screen relative stability when rotating, and promptly rotate at grade.
