Abstract
The utility model relates to a vertical type axial-flow threshing machine which is used for the threshing, the separating, the wind separating and the filtrating of the rice and wheat. The utility model is composed of an outer shell, a machine frame, a cylinder, fans, an escape grid, wind selecting panels with annular openings, a grain scraping speed reduction mechanism, an eccentric wheel four connecting rods transmission mechanism and a vibration sieve. Because the wind selecting panels with annular openings which are used as the outlet of the glume mixture are arranged on the upper part of the escape grid and the bottom of the fans, which make the wind selecting of the separated object have a long time, big space and a thorough wind selecting; because an eccentric wheel four connecting rods transmission mechanism is arranged on the grain scraping speed reduction mechanism, and drives the vibration sieve filtrating, so the cleanliness of the threshing is exceed 99%. The utility model has the advantages of safe using and light weight.
Description
The utility model is a kind of annular aperture selection by winnowing plate that is provided with, double-deck outlet, the vibratory sieve that direction is opposite, the vertical axial-flow thresher of the selection by winnowing that suspends and vibration screening.This machine is applicable to rice-wheat threshing, separation, selection by winnowing, screening, and can with the supporting use of combine.
Existing a kind of vertical axial-flow thresher, its dressing mechanism are that the ejecting port of concave grate top, grass outlet downside communicates with the inlet scoop at the grain-scraping plate place, bottom of concave grate by the separation chamber, and the top, space between concave grate and the shell is closed.Its selection by winnowing process be separator by concave grate after, seed, grain husk assorted drop to grain-collecting disc, become to heap shape, scrape by grain-scraping plate and carry out selection by winnowing to the inlet scoop.Its defective is: under the fan effect above the cylinder, air-flow moves from bottom to top, the clever foreign material that proportion is little rise with air-flow, but the top, space between concave grate and the shell is closed, the assorted No way out of the grain husk that rises, poly-more many more, must result in blockage, seed can't separate with grass, working condition worsens.Separator drops to grain-collecting disc and becomes the heap state, has increased the weight of the easy stuck and gross distortion of load, grain-scraping plate of grain-scraping plate.Drop to separator on the grain-collecting disc have only be pushed into the place, inlet scoop by grain-scraping plate could be by selection by winnowing, the selection by winnowing time is short, selection by winnowing is not thorough.Cleannes are less than 90%(national standard 98%).
The purpose of this utility model be solve that the separation process of present vertical axial-flow thresher is easily stifled, seed percentage of impurity height, insecure shortcoming of working; provide and have the assorted outlet of grain husk on the circular openings selection by winnowing plate of a kind of top, fan bottom at concave grate; has the seed of making under action of centrifugal force; carry out selection by winnowing when being in suspended state when separating with the stem grass, and the vertical axial-flow thresher of screening function is arranged by concave grate.
The said a kind of vertical axial-flow thresher of the utility model is to be made of shell, frame, cylinder fan, concave grate, annular aperture selection by winnowing plate, grain-scraping plate reducing gear, eccentric wheel four jointed gear units, vibratory sieve assembling.Its technical characterictic is: below the top of concave grate, fan annular aperture selection by winnowing plate is housed; Eccentric wheel four jointed gear units are housed on the grain-scraping plate reducing gear, are contained on the fork on the frame vibratory sieve is housed.
Being peripherally equipped with concave grate, below the top of concave grate, fan, being provided with annular aperture selection by winnowing plate at cylinder, have the assorted outlet of grain husk on the selection by winnowing plate, the assorted outlet of its grain husk top communicates with grass outlet, the assorted outlet of grain husk lower end communicates with the annulus of concave grate, shell formation.And the air admission hole of opening with the shell circle wall constitutes the selection by winnowing passage.Four jointed gear units that eccentric wheel constitutes are housed on the grain-scraping plate reducing gear on the drum shaft, and driving has the opposite vibratory sieve of double-deck Way out.
When operation start, wait to take off thing and feed from feeding mouth, under the cylinder action of centrifugal force of high speed rotating, make and wait to take off the thing threshing, seed, grain husk be assorted to be separated with the stem grass, the stem grass is discharged outside the machine at a high speed from grass outlet.Export by the grain husk on the annular aperture selection by winnowing plate is assorted in the effect of grass outlet fan, the negative pressure that high velocity air produces, annulus at concave grate and shell forms the air-flow that rotation is risen, when seed and clever foreign material pass concave grate, become suspended state, the clever foreign material that proportion is little are rotated the air communication of rising and cross the assorted outlet of grain husk outside grass outlet discharge machine.Seed and heavy cane drop on the chassis, scrape to vibratory sieve by grain-scraping plate and screen.Bigger clever foreign material are discharged for assorted mouthful from the grain husk of screen cloth, discharge from the mouth of putting out cereal of grain-collecting disc through the seed of screening.
The utility model has the advantages that: this machine novel structure, simple, compact, because circular openings selection by winnowing plate is positioned at the top of concave grate, air-flow moves from bottom to top, make that the selection by winnowing space is big, the time is long, cereal is in separation process, and separator is suspension, big, the easily effusion in windward side, selection by winnowing is thorough; Fall into and have only seed and cane at the bottom of the chassis, alleviated the load of grain-scraping plate, reduced power consumption, eliminated the stuck phenomenon of grain-scraping plate; Owing to eccentric wheel four jointed gear units are housed on the grain-scraping plate reducing gear, have simplified the vibration transmission mechanism; Owing to whole double-deck oppositely outlet vibratory sieve is housed, can screens again, thereby make the threshing cleannes surpass 99%(national standard 98%).Complete machine is in light weight, and is safe and reliable, the social benefit height.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
