Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, of the invention is to include cterpillar drive 13, frame 12, hair with existing harvester something in common
Motivation 14, sheller unit 5 and grain lifter etc., difference is：Grain lifter includes wind regime 1, and wind regime 1 can drive air by cutting
Moved after the front direction of knife 7.
Wind regime 1 can drive air to be moved by after the front direction of cutter 7.Can be specifically that induced-draught fan is set at the rear of cutter 7,
But the way of recommendation of the present invention is that, using air blower 2, air blower 2 produces wind-force that grain ear is blown to harvester rear.For example：Such as Fig. 1
With shown in Fig. 8, wind regime 1 includes guide duct 3 and the air blower 2 with the first air outlet 10, after air blower 2 is arranged at cutter 7
The connection of side, the rear end of guide duct 3 and the first air outlet 10, the front portion of guide duct 3 is provided with the second air outlet 6, the second air outlet 6
Positioned at the front of cutter 7 and towards the rear of harvester；Wind regime 1 is located at harvester bottom, wind regime 1 shown in Fig. 8 wherein shown in Fig. 1
Positioned at harvester top.As shown in figure 9, air blower 2 is arranged at the front upper place of cutter 7, the first air outlet 10 is towards harvester
The back lower place.Far according to engine 14 when being arranged at 7 front of cutter due to air blower 2, the driving of air blower 2 is more inconvenient, therefore
It is preferable that air blower 2 is arranged at the rear of cutter 7.
When carrying out rice harvesting using the present invention, harvester is advanced, and when cutter 7 reaches paddy rice, wind regime 1 drives air to produce
Wind-force paddy rice is blowed into cutter 7, play and help standing grain to act on.After cutter 7 cuts off grain ear, wind-force continuation effect, can by grain ear to
Blow at harvester rear so that grain ear can enter sheller unit 5, play auxiliary charging effect；Wind-force can even continue effect,
After the threshing of sheller unit 5, stalk is blown out into sheller unit 5 by the stalk outlet 22 of sheller unit 5.
As it was previously stated, grain ear can be blowed to sheller unit 5 by grain lifter, therefore the present invention can save prior art
The feeding device that grain ear is drawn in and conveyed backward, it is only necessary to which passage of the grain ear by cutter to sheller unit 5 is set, specifically such as
Under：Wind-force help standing grain formula harvester include sheller unit 5, conveying base plate 8 and shield 4；Sheller unit 5 is located at the rear of cutter 7, takes off
Material inlet is provided with grain device 5；Conveying base plate 8 extends to cutter 7 by material inlet lower edge；Shield 4 is located at conveying bottom
The top of plate 8, around material inlet, the front end of shield 4 extends to the front of cutter 7 for the rear end of shield 4；The shield of the top of conveying base plate 8
Space is material channel 11 in cover 4；Second air outlet 6 is located in material channel 11.Grain ear enters threshing and fills by material channel 11
Put 5, shield 4 and conveying base plate 8 are grain ear motion guide, grain ear can be avoided to be blown down outside harvester, reduce Grain Loss rate.
As it was previously stated, air blower 2 is preferably arranged at the rear of cutter 7, but if wind regime 1 is located at harvester top as shown in Figure 8,
Then need to be dried to rear under harvester, be unfavorable for gathering in the paddy rice of certain lodging.Therefore best mode is as shown in Figure 1：
The drive shaft 9 of air blower 2 is located at the lower section of conveying base plate 8, and the second air outlet 6 is located at the bottom of material channel 11, before guide duct 3
Portion is pre-small post-large structure.Second air outlet 6 is located at the bottom of material channel 11, and position is relatively low, and wind-force will can have necessarily to fall
The paddy rice of volt is blown afloat, and is conducive to gathering in the paddy rice of certain lodging.Before cutter being located at because guide duct 3 is anterior, guide duct 3 pairs
Paddy rice has certain stop, and the front portion of guide duct 3 is that the effect of pre-small post-large structure is to reduce guide duct 3 to greatest extent to stop water
Rice enters harvester.
In order to air-out is more evenly distributed in conveying passage 11.The anterior setting front and back position of guide duct 3 is different at least
Two the second air outlets 6, the second air outlet 6 rearward does not stop the air-out of the second forward air outlet 6.
Grain lifter should be set according to the swath of harvester, when swath is narrow, can be as shown in Figures 2 and 3：The quantity of wind regime 1 is
Two pieces, two pieces wind regime 1 is symmetrical arranged, and the second air outlet 6 of two pieces wind regime 1 is located at the both sides of material channel 11.
When swath is medium, can be as shown in Figure 4 and Figure 5：The quantity of wind regime 1 is three；The both sides of one wind regime 1 are provided with
Two air outlets 6, the air outlet 6 of wind regime 1 second is located at the middle part of material channel 11；Other two pieces wind regime 1 is symmetrical arranged, this two pieces wind
Second air outlet 6 in source 1 is located at the both sides of material channel 11.
When swath is wide, can be as shown in Figure 6 and Figure 7：The quantity of material inlet, conveying base plate 8 and shield 4 is two, defeated
Material base plate 8 and shield 4 are corresponded to set with material inlet and form two material channels 11；The quantity of wind regime 1 is five；One wind
Source 1 is located between two material channels 11, and the both sides of the wind regime 1 are provided with the second air outlet 6, and the second of the both sides of wind regime 1
Air outlet 6 is located in two material channels 11 respectively；The both sides of other two pieces wind regime 1 are equally provided with the second air outlet 6, this
Second air outlet 6 of two pieces wind regime 1 is located at two middle parts of material channel 11 respectively；6 points of second air outlet of last two pieces wind regime 1
Wei Yu not two outsides of material channel 11.
The driving of each air blower 2 when having multiple air blowers 2 for convenience, each air blower 2 is coaxially disposed, and by same drive
Moving axis 9 drives.
The present invention can also be provided with lifting device 15, and the effect of lifting device 15 is that the grain that sheller unit 5 is exported is kicked up, and is easy to
Grain is exported to outside harvester.Lifting device 15 specifically can be as shown in Figure 10 to Figure 12：The paddy of lifting device housing 19 and sheller unit 5
Grain outlet is correspondingly arranged；Lifting device axle 16 is horizontally arranged with glassware housing 19, the middle part of lifting device axle 16 is connected with lifting device leaf
Piece 21, the both sides of lifting device blade 21 are provided with the conveying spiral 18 being connected with lifting device axle 16；Discharge nozzle 20 tilts upward setting,
The lower end of discharge nozzle 20 is connected with lifting device housing 19, and corresponding with the material outlet position that the middle part of lifting device housing 19 is set；Raise
Lifting device housing 19 is stretched out in the one end of glassware axle 16, and is connected with driving wheel 17.The course of work of lifting device 15 is as follows：Sheller unit 5
The grain of output enters the bottom of lifting device housing 19, and engine 14 drives driving wheel 17 and lifting device axle 16 to rotate, lifting device axle
16 drive conveying spirals 18 and lifting device blade 21 rotate, and conveying spiral 18 draws at lifting device blade 21 grain in, lifting
Device blade 21 rotates kicks up into discharge nozzle 20 grain, and grain is exported outside harvester by discharge nozzle 20.
The present invention is described by taking rice harvester as an example, but grain lifter of the invention is applicable not only to rice harvesting
Machine, applying also for wheat harvester etc. needs to help the harvester of standing grain.What accompanying drawing of the invention was represented is small harvester, but this hair
Bright grain lifter is applicable not only to small harvester, applies also for big-and-middle-sized harvester.
