Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment 1 of the combine harvester of the utility model is pacified on car body as shown in Figure 1 to Figure 3, including car body
Equipped with cleaning plant is taken off again, take off cleaning plant again includes paddy code paddy code re-threshing roller and cleaning plant again.Paddy code paddy code is multiple de-
Roller includes outer barrel 6 and the inner cylinder 8 with the coaxial arrangement of outer barrel 6, and the front end of outer barrel 6 passes through outer barrel spring bearing
2 fix on the car body, 6 both ends open of outer barrel, and front opening is to enter to for the mixed material after master rotor threshing separation
Feed inlet inside paddy code re-threshing roller, the rear end of cylinder passed through by inner cylinder, and with 8 rolling assembling of inner cylinder, the present embodiment
In inner cylinder 8 and outer barrel 6 pass through 10 rolling assembling of planetary gear transmission mechanism.The advantages of designing in this way is that planetary gear passes
Motivation structure 10 is compact-sized, and transmission stability is high, helps to realize the reasonable disposition of device, and inner cylinder 8 is nibbled with outer barrel 6
10 transmission ratio of planetary gear transmission mechanism of conjunction is not equal to 1, and the purpose designed in this way is poor in order to realize inside and outside cylinder 8,6
Speed movement rolls duration to facilitate growth and treat threshing paddy code, and then improves and roll Threshing.Inner cylinder in the present embodiment
Drive pulley 11 on body 8, which is driven by transmission belt by driving motor, realizes that inside and outside cylinder relatively rotates, certainly in other implementations
Drive pulley 11 may also be arranged on outer barrel 6 in example.6 inner surface of outer barrel is welded with screw feeder 7 in outer barrel, inside outer barrel
Leading portion is equipped with pressure roller 4, and the pressure roller 4 in the present embodiment is four, wherein two-by-two positioned at the same circumference of outer barrel and in circumference
On be evenly arranged, the pressure roller 4 in outer barrel axial direction is located along the same line, the benefit designed in this way be meet can purify paddy
Using less pressure roller 4 while object, the manufacturing cost of the utility model is on the one hand reduced, on the other hand reaches and purifies paddy code
Purpose.Certainly, in other embodiments, the quantity of pressure roller 4 can also be two, three, six, the arrangement form of pressure roller 4
Other forms can be used.4 outer surface of pressure roller in the present embodiment is machined with helicla flute 401, and the purpose of setting helicla flute 401 is
In order to make helicla flute 401 convey paddy material.Outer barrel 6 the rear side of pressure roller 4 partially circumferentially on be covered with sieve pore, the diameter of sieve pore is slightly larger
In grain partial size, grain is enable to fall by sieve pore.
Inner cylinder 8 in the present embodiment is cylinder closed at both ends, and the front end of cylinder is close to the one of 6 feed inlet of outer barrel
End is taper approach section 1, and the purpose designed in this way is to enter paddy code re-threshing roller for the ease of the cereal to threshing.With outer barrel
It is provided with the corresponding inner cylinder 8 of sieve pore section on 6 and is equipped with sieve pore, the sieve pore that grain can be allowed to fall is set simultaneously on inside and outside cylinder,
Be conducive to cereal and fall into discharge port.Meanwhile the grain fallen into inside inner cylinder 8 in order to prevent cannot be introduced into discharge port, inner cylinder 8
Interior welds have screw feeder 3 in inner cylinder, and the grain for falling into inner cylinder can be moved backward by screw feeder 3 in inner cylinder falls into outer barrel
Discharge port.The rear end of inner cylinder is equipped with impurities removal plate 9, and the miscellaneous remaining and broken stem of the paddy code after threshing can be by being arranged on outer barrel
Impurity discharging port discharge.
Cleaning plant 12 in the present embodiment includes tubular shell, tubular shell character form structure for it, zigzag tubular shell
The break of the both ends of body and its two bending places sets gradually feed hopper 14, grain outlet 15, crossflow fan 13 and clever bran outlet 16.
Feed hopper 14 and grain outlet 15 have certain slope, and the purpose designed in this way is the paddy material for making to be discharged from 6 discharge port of outer barrel
Can easily it enter inside cleaning plant 12, grain outlet 15 is located at 12 lower part of cleaning plant, and grain can be sliding by gravity
It falls.Crossflow fan 13 in the present embodiment is located at the oblique upper of grain outlet 15, and clever bran outlet 16 is located at the oblique of crossflow fan 13
Lower section, in this way design help so that the clever chaff being entrained in grain is extracted out and be smoothly discharged by crossflow fan 13.
The combine harvester of the utility model is in use, the mixed material separated through sheller unit notch board（Grain, paddy
Code, clever chaff, broken stalk）Crawl and push feeding are realized by the screw feeder blade that welds on taper approach section 1, first through pressure roller 4 with
The operation de- again of the upper grain of coordinating operation completion paddy code of cylindrical section before inner cylinder 8, the mixed material after taking off again is outside inner cylinder
It is conveyed under the common push effect of helicla flute 401 on 5 blade of screw feeder and pressure roller 4 to back segment.Then 7 leaf of screw feeder in outer barrel
Under the conveying of piece, tiny grain and clever chaff enter cleaning plant through the discharge port on outer barrel.The miscellaneous remaining and broken stalk warp of paddy code
Impurities removal plate 9 by impurity discharging port discharge machine outside.Wherein 3 blade of screw feeder also ensures the grain and grain husk fallen into inside inner cylinder in inner cylinder
Chaff is moved to device back segment.Grain and clever chaff by cleaning plant during being fallen, due to the air of the two in the gas flow
Kinetic characteristics are different, by controlling the revolving speed of crossflow fan, it can be achieved that the clever chaff of lighter weight is sucked out by crossflow fan
And by clever bran outlet discharge, and the grain of heavier mass is then fallen into silo due to the effect of gravity from grain outlet.
