Beneficial effect described in the utility model：
1) the utility model added on the basis of back-flexing stretching harvesting is carried out to fruit ear swing to fruit ear and
Impact, the harvesting tensile force of needs is further reduced while the success rate for improving harvesting, and then reduce corn stem
Stress, therefore the extruding force for the stem pulling roller for reducing corn stem and being subject to obtain enough stem drawing forces, reduce to corn
The destruction of stalk, avoid stalk from being broken in corn-cob picking procedure and cause harvesting failure and fruit ear percentage of impurity high；
2) structure stem pulling is realized before realizing the back-flexing stretching harvesting mode of corn relatively using four roll structures more
Reliably, and mode of the stem pulling roller as lifting conveying corn stem is used, corn stem force position is constantly changed, avoided
All the time acting on a little causes stalk to be broken；Traditional structure stem pulling structure and the angled configuration of harvesting structure, realize both synchronous fortune
Dynamic drive mechanism is complicated, the utility model four-roller configured in parallel, reduces the complexity of drive mechanism.
3) due to the up-thin-low-thick structure of corn stem, when stem pulling roller works, as corn stem is drawn above stem pulling roller
Go out, stem pulling roller increases the extruding force of corn stem, can when corn ear is not in contact with to snapping bar fast pull-up stalk, when
Fruit ear contact snapping bar carries out during harvesting stem pulling roller being made to clamp maximum intensity in the stalk of corn ear top as far as possible
Position, avoid stalk fracture cause harvesting to fail；
4) stem pulling roller continues extruding and is pulled up corn stem after harvesting success, because of corn stem diameter uneven distribution,
So stem pulling roller can carry out crushing silk to stalk fringe lower part, it is easy to follow-up straw chopping returning to the field or briquetting to handle；
5) haling section and can be separated with stem pulling roller on the utility model stem pulling roller, it is conveniently replaceable after section abrasion is haled；

Key connection is on axle, and the first sprocket wheel 210 and the second sprocket wheel 220 are by key connection on stem pulling roller 110a axle；Clutch shaft bearing 150
Installed with second bearing 160 in certain distance, to produce support torque to balance torque caused by stem pulling roller stress F.
As shown in Figure 1 and Figure 4, snapping bar 510a and 510b are organized in pairs, the equidirectional rotations of snapping bar 510a and 510b, are turned
Dynamic direction is as signified such as arrow in Fig. 6, snapping bar 510a and 510b synchronous axial system；Snapping bar 510a and 510b are eccentric rollers, with
Exemplified by snapping bar 510a, including：Starting taper section 510a-1, harvesting section 510a-2 and rear shaft part 510a-3, starting taper section 510a-1 are set
It is taper to put in snapping bar 510a-1, can import corn stem；Harvesting section 510a-2 one end and the one of starting taper section 510a-1
End connection, and it is provided with helical structure；Shaft part 510a-3 one end is connected with the other end of the harvesting section 510a-2 afterwards, directly
Footpath is less than the harvesting section；
Wherein starting taper section 510a-1 and rear shaft part 510a-3 axis are concentric, with harvesting section 510a-2 axis decentractions, skew
Distance is Δ, wherein snapping bar 510a (including rotary orientation is also identical) identical with snapping bar 510b structure.
Snapping bar 510a and snapping bar 510b synchronous axial systems, and have initial makeup location, as shown in figure 5, installation is initial
When ensure that established angle δ and δ ' is equal, the vertical line in snapping bar 510a-2 as shown in Figure 5 axle center and 510a-3 axle center and pluck
The axle center vertical line of fringe roller 510b harvesting Duan Yuhou shaft parts is parallel and the anglec of rotation is identical (i.e. δ=δ '), ensures that two eccentric rollers exist
Interfered in the middle part of synchronous equidirectional rotation, above-mentioned installation is to ensure snapping bar 510a and 510b bias with the kind of drive
Special construction is at work so that any point is moving in a circle around starting taper section axis on the outer surface of snapping bar harvesting section
Meanwhile swing effect is produced to the corn stem between two snapping bars.
The purpose of this working method is so that snapping bar 510a and snapping bar 510b is touched into wherein plant
Fruit ear when have one to fruit ear while swing and pull down impact, pass through the spiral knot on snapping bar 510a and snapping bar 510b
Structure conveys stalk and fruit ear backward, and realization is synchronous with stem pulling roller 110a and 110b conveying stalk, while improving harvesting success rate
Power consumption is further reduced, while conveying effect is also avoided that snapping bar 510a and snapping bar 510b is blocked.
Illustrate the course of work of this ear-picking unit with reference to Fig. 6；During work, corn stem conveys winder part by front and sent
Enter in front of two stem pulling rollers and two snapping bars, then by the starting taper part and the starting taper portion of two snapping bars of two stem pulling rollers
Divide and corn stem is sent into stem pulling roller 110a, 110b and snapping bar 510a and 510b；At the same time, cutter is by plant
Cut-out realizes that stalk separates with root, while then stem pulling roller 110a and 110b captures corn stem and pull up corn stem
Convey backward, while snapping bar 510a and 510b also convey corn stem is synchronous with stem pulling roller 110a and 110b backward, because of two
Gap between individual snapping bar is larger, and corn stem can rise with stem pulling roller stem pulling, and then between corn ear and snapping bar
Distance reduce until both be in contact, then stem pulling roller continues to pull up stalk, and corn ear is stopped by two snapping bars, harvesting
Roller 510a and 510b in rotary course because the corn ear that its eccentric structure can make to be in contact with it constantly swings, and
Impact fruit ear auxiliary harvesting downwards；Stalk and fruit ear can be also conveyed backward simultaneously, it is synchronous with the holding of stem pulling roller, avoid blocking,
Finally realize harvesting.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
