Description
Technical field
The utility model belongs to agricultural machinery technological field, specifically, going out in particular to a kind of maize harvesting machine
Stubble knife.
Background technique
Maize harvesting machine, according to its planting patterns, agriculture requirement, is completed with mechanical to corn in corn maturation
The work tool of the production links such as rotary tillage soil after stem cutting, harvesting, peeling, threshing, stalk processing are even gathered in.Existing jade
Blade for cleaning stubble on rice cropper is made of single straight knife, can be only done the cutting of stalk radial direction, when only relying on high speed rotation
Stalk is blown down carry out transversely cutting by the air-flow of generation, therefore is only suitable for thinner, soft stalk crushing and is used, and the characteristic of cornstalk
Sturdy, flexible, using traditional blade for cleaning stubble cannot sufficiently, completely crushing straw.
Utility model content
In view of the above drawbacks of the prior art, the technical problem to be solved by the utility model is to provide a kind of corn receipts
Obtain machine stubble-cleaning knife.
Technical solutions of the utility model are as follows：A kind of maize harvesting machine stubble-cleaning knife, it is characterised in that：Along it on movable arbor
Axial that multiple flail knife blade units are arranged, each flail knife blade unit has two groups of circumferentially equally distributed flail knives, every group of flail knife
It is made of the first curved flail knife, the second curved flail knife and the straight flail knife between two curved flail knives, the free end of each curved flail knife is equal
Away from the direction bending of straight flail knife, bending section is formed, the angle a between the bending section and straight flail knife is acute angle.
Using above technical scheme, every group of flail knife is made of the first curved flail knife, the second curved flail knife and straight flail knife, every group of flail knife
Cooperate with two ledger-plates, when work its revolving speed at 1300-1800 revs/min, can sufficiently, completely crushing straw, make to go out
Stalk after stubble was both short and broken.The utility model structure is simple, and production and installation easy to process are effectively improving stubble-cleaning effect
Meanwhile functional requirement is able to achieve just with lower revolving speed, greatly reduce energy consumption.
Preferably, the two sides of the straight flail knife free end are symmetrically arranged with the first cutting edge face, each first cutting edge is set on face
Set the first sawtooth.
Preferably, the two sides of each curved flail knife bending section are symmetrically arranged with the second cutting edge face, each second cutting edge is set on face
Set the second sawtooth.
Preferably, the first curved flail knife and the second curved flail knife are symmetrical in the two sides of straight flail knife, each curved flail knife bending section
Angle a between straight flail knife is 30 °.Angle a is excessive or too small all easy and ledger-plate generation is interfered, and in turn results in blade quilt
It breaks；Angle a selects 30 °, while preventing blade interference damage, it can be ensured that stubble-cleaning effect.
In order to simplify structure, convenient for assembly, keep flail knife installation firm, two groups of flail knives of each flail knife blade unit are installed on together
On one tool apron, the installation end of every group of curved flail knife of flail knife first, straight flail knife and the second curved flail knife is respectively positioned on the two pieces small vertical of tool apron
Between plate, and it is fixedly connected by pin with small vertical plate.
Preferably, between the installation end of the in group first curved flail knife and the installation end of straight flail knife and the installation of straight flail knife
Washer is provided between end and the installation end of the second curved flail knife.
Beneficial effect：The utility model structure is simple, is easily assembled, can compared under the slow-speed of revolution sufficiently, completely crush
Stalk, the stalk after making stubble-cleaning was both short and broken, not only reduced energy consumption, and ensured stubble-cleaning effect, for various types of
Cornstalk is all suitable for.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figures 1 to 5, multiple flail knife blade units, the number of flail knife blade unit are axially set along it on movable arbor 1
Determine according to actual needs, the present embodiment is preferably four, and the distance between two adjacent flail knife blade units are equal.Each flail knife piece
Unit has two groups of circumferentially equally distributed flail knives, and every group of flail knife is by the first curved flail knife 2, the second curved flail knife 3 and positioned at two
Straight flail knife 4 between a curved flail knife forms, and two groups of flail knives of each flail knife blade unit are installed on the same tool apron 7, and tool apron 7 is solid
Surely it is sleeved on movable arbor 1.
As shown in Figure 1, the installation end of every group of curved flail knife 2 of flail knife first, straight flail knife 4 and the second curved flail knife 3 is respectively positioned on tool apron 7
