Technical field
The invention belongs to agricultural mechanical field, in particular to a kind of cutting type corn harvester.
Background technique
Corn is food, feed and the important source material of industry, total output occupies at present as one of China's Three major grain crops
Second place of the world.Corn harvesting machine plays the important and pivotal role in the harvest of corn.However, current maize harvesting machine
The problems such as development is simultaneously immature, and loss late is high, stability is poor, bad adaptability, high energy consumption seriously constrains the harvest corn in China
Mechanization Level.
Ear-snapping unit determines the key technical indexes of complete machine harvesting performance, such as grain loss in maize harvesting machine
Rate, percentage of damage etc..Currently, ear-snapping unit is broadly divided into screw thread harvesting roll-type and harvesting plate and stem pulling roller from working principle
Combined type；It is horizontal harvesting roll-type, vertical harvesting roll-type, horizontal type harvesting roll-type respectively there are mainly four types of from structure type
It is board-like with vertical sleeping harvesting.Seed breakage rate caused by existing ear-snapping unit, loss late, fruit ear loss late and existing country
There is also certain gaps for standard.Horizontal harvesting roll-type ear-snapping unit is inevitably resulted in due to its working principle to fruit
The damage of fringe.Structure is complicated for vertical harvesting roll-type ear-snapping unit, and energy consumption is also larger.Horizontal type harvesting roll-type corn picker
Device easily chews fruit ear or brings fruit ear into snapping bar and causes to lose.Stalk meeting is broken in the vertical board-like rice ear-picking unit pressure of sleeping harvesting
A large amount of power are consumed, percentage of impurity is high.
Recent some scholars have devised in the principle of research bendable harvesting and convey cornstalk stem by clamping and conveying device, pluck
Fringe roller generates the bionical ear-snapping unit of bending power to corn ear；And it is rotated in plant side by fruit by wheeled ear poking roller
Ear poking roller formula ear-snapping unit under fringe " beating ".By the ear-snapping unit of clamping and conveying device conveying, structure is complicated, sprocket wheel work
There is unstable hidden danger, and corn ear is directly acted on by snapping bar, fruit ear can be caused to damage.Ear poking roller formula corn picker dress
Set that structure is complicated, poor work stability.
Summary of the invention
In view of the above technical problems, the object of the present invention is to provide a kind of saving energy, be effectively reduced fruit ear loss late and

15。
2 front end of cutter device mounting plate is connected with tensioning wheel mounting plate 4.
The rice-pulling chain 1 is set in driving wheel group 6, and passes through the driving rotation of driving wheel group 6.The driving wheel group 6 is wrapped
Include driving gear, driven gear and Tension gear；Driving gear and the line at driven gear center are parallel to the work of harvesting monomer
Face A.Driving gear is mounted in the drive shaft of cropper, and driven gear is mounted on cutter device mounting plate 2, Tension gear peace
On tensioning wheel mounting plate 4.
The grain lifter 3 covers on 1 top of rice-pulling chain, fixes pacify with cutter device mounting plate 2 and tensioning wheel mounting plate 4 respectively
Dress.
The snapping bar 5 is located at the lower section of cutter device mounting plate 2, and is parallel to harvesting Single working face A, and with harvest
The snapping bar of machine drives axis connection.5 surface of snapping bar is equipped with spiral boss, and two snapping bars 5 of harvesting monomer turn in opposite directions
It is dynamic.
As shown in Fig. 3 a~Fig. 3 c, the cutter device 15 includes rubber buffer cover 7, cutter 8 and spring regulating device 9.
Cutter 8 is vertically fixed on cutter device mounting plate 2 near and parallel to harvesting Single working face A.The left and right sides of cutter 8
It is evenly distributed with multiple spring regulating devices 9.Rubber buffer cover 7 has elastic sidewall and top plate, is covered on cutter 8 and spring is adjusted
The top of device 9；The height of 7 side wall of rubber buffer cover is equal to the height of cutter 8；Offered on the top plate of rubber buffer cover 7 with
The corresponding slot of cutter 8, when the top plate of rubber buffer cover 7 is not affected by external force extruding or smaller external force, rubber buffer cover 7
Deformation occurs or deformation is smaller for side wall, and the blade of cutter 8 can cut off to avoid cutter 8 and tilt in rubber buffer cover 7
Corn stem and leaf；When the top plate of rubber buffer cover 7 is squeezed by larger external force, i.e., compared to corn stem and leaf compared with
When having squeezing action for top plate of the hard corn ear to rubber buffer cover 7, larger shape occurs for the side wall of rubber buffer cover 7
Become, exposes the blade of cutter 8 from the slot on the top plate of rubber buffer cover 7, corncob shank position is cut off.Rubber
The lower surface of the top plate of impact-absorbing shell 7 is contacted with spring regulating device 9, adjusts rubber buffer cover 7 by adjustment spring regulating device 9

On the nut fixation hole opened up on cutter device mounting plate 2；The head end for adjusting bolt 14 is worn from 2 bottom of cutter device mounting plate
Fixture nut 13 is crossed, it is affixed with spring lower gasket 12.The following table of the top plate of the upper surface and rubber buffer cover 7 of spring Upper gasket 10
Face contact；Bolt 14 is adjusted by rotation to adjust the compression degree of spring 11, for adjusting the support of rubber buffer cover 7
Power, and then realize that cutter 8 does not cut off corn stem and blade, only there is dissection to corn ear.
The course of work of the invention is as follows:
When work, plant moves backward relative to cutting type corn harvester, is fed into plucking for harvesting monomer
Between two snapping bars 5 of fringe Single working face A, 5 surface of snapping bar is equipped with spiral boss, and two snapping bars 5 rotate towards each other, band
Dynamic plant moves backward while moving downward.When plant moves downward, grain lifter 3 plays the work for propping up stalk
With so as not to topple over.When corn leaf and plant are pulled to cutter device 15 by snapping bar 5, since leaf softness is deformable,
So that leaf does not have enough extruding forces to the top plate of rubber buffer cover 7, the blade of cutter 8 is maintained in rubber buffer cover 7, from
Without being cut to stalk and leaf.
When corn ear is pulled to cutter device 15 by snapping bar 5, since fruit ear is more hard and flexible poor, Bu Nengshun
Benefit has biggish squeezing action, rubber buffer cover 7 to the top plate of rubber buffer cover 7 by the gap between two snapping bars 5
Side wall larger deformation occurs, expose the blade of cutter 8 from the top plate of rubber buffer cover 7, to generate to corncob handle
Cutting action.The corn ear cut is stirred backward through rice-pulling chain 1, is collected.
