Description
Technical field
The invention belongs to agricultural machinery technological fields, specifically, the present invention relates to a kind of sheller units.
Background technique
Existing sheller unit includes threshing chamber and the threshing cylinder that is set in threshing chamber, and threshing is indoor most of empty
Between be used as the configuration space of threshing cylinder, and the only small space that remains in around threshing cylinder is used as threshing processing
Processing space, the processing space are formed between the inner wall of threshing chamber and the periphery of threshing cylinder (referring to patent document 1).
[existing technical literature]
[patent document 1] Publication No. CN103125217A
But in the sheller unit of patent document 1, smaller, the threshing roll of the processing space setting around threshing cylinder
Cylinder surrounding non-process space is arranged larger.Straw will be largely gathered in as threshing processed material in harvester high-speed job to supply
When being given to threshing chamber, there are the danger of processing space saturation, and when the saturation occurs, since threshing processed material is trapped in processing
In space, therefore it is easy to cause threshing processed material not carry out the unfavorable condition that sufficient threshing processing is just leaked down from bearing net and occurs,
Processing capacity reduces；And when the saturation occurs, threshing processed material increases so that threshing indoor threshing load becomes larger, then takes off
The cylinder of grain roller is by the load by thrashing cylinder axis (axis of the rotation center as threshing cylinder) side is pressed to, and there are barrel distortions
The problem of.What non-process space was arranged around threshing cylinder is larger, when the saturation occurs, since threshing processed material can be from processing
Space compressional movement is easy to cause threshing processed material not carry out threshing processing and is just discharged outside body to non-process space；In addition,
The problem of stalk of threshing processed material easily winds cylinder shaft, will lead to threshing cylinder blocking appearance.

3801 outside the first threshing finger 3802 outstanding of grain ratch protrudes into the first processing space 312.First threshing toothed bar 3801 with
Width disk 315 is fixedly connected, and multiple first threshing fingers 3802 are on the first threshing toothed bar 3801 for along the first threshing toothed bar 3801
Length direction interval setting.Second ratch soldering 309 include second threshing toothed bar 3901 parallel with thrashing cylinder axis 316 and
It is set on the second threshing toothed bar 3901 and towards the outside of the second threshing toothed bar 3901 multiple second threshing fingers 3902 outstanding,
It is protruded into the first processing space 312 towards 3901 outside the second threshing finger 3902 outstanding of the second threshing toothed bar.Second threshing
Ratch 3901 is fixedly connected with width disk 315, and multiple second threshing fingers 3902 are de- along second on the second threshing toothed bar 3901
The length direction interval setting of grain ratch 3901.
As shown in Figure 3 and Figure 5, the first threshing toothed bar 3801 and the second threshing toothed bar 3901 are cylindrical tube, and first is de-
Grain ratch 3801 and the axle center of the second threshing toothed bar 3901 are on same circumference, multiple first threshing toothed bars 3801 and multiple the
Two threshing toothed bars 3901 are being circumferentially about uniformly distributed in thrashing cylinder axis 316 using the axis of thrashing cylinder axis 316 as center line,
Each second threshing toothed bar 3901 is between two adjacent the first threshing toothed bars 3801 and each threshing toothed bar and two sides
The distance between two the first threshing toothed bars 3801 are equal.Preferably, two neighboring on the second threshing toothed bar 3901
Two threshing fingers 3902 are interlaced arrangement, have angle and the folder between the length direction of two neighboring second threshing finger 3902
Angle is acute angle, that is, the multiple second threshing fingers 3902 being set on the second threshing toothed bar 3901 arrange that respectively arranges is more in two rows
A second threshing finger 3902 is to be arranged along the length direction interval of the second threshing toothed bar 3901.It crosses the second ratch soldering 309
On threshing finger interlaced arrangement, can be further improved the processing capacity of sheller unit.
In the present embodiment, as shown in Figure 3 and Figure 5, the first ratch soldering 308 and multiple second ratch soldering 309 are divided equally
It She Zhi not be three.
