Description
Technical field
The present invention relates to a kind of threshing apparatus, especially a kind of board-like threshing cylinder belongs to agricultural machinery technological field.
Background technique
Soybean is pod easy to crack, frangible crop, and the rigid threshing cylinder such as traditional spike-tooth, rasp bar and threshing element are in threshing
It is larger to the strike of soybean kernel when operation, cause soybean threshing, harvest percentage of damage high, extreme influence soybean harvest quality.
The prior art realizes that the typical structure of soybean threshing is application number 201120009390.0, title " soybean harvester
Threshing cylinder " Chinese patent literature disclose, using spiketooth type threshing element, traditional round width is substituted using three angular width disks
Disk, and replace 6 traditional rooted tooth bars using 3 rooted tooth bars, although being simplified in structure, not only rigid threshing toothed bar
It is high for soybean threshing percentage of damage, and do not have cylinder-concave clearance regulatory function, it is difficult to adapt to different cultivars soybean threshing operations
Needs.
Summary of the invention
It is an object of the invention to: in view of the problems of the existing technology, one kind is provided under the premise of keeping threshing efficiency,
Soybean threshing course percentage of damage can be significantly reduced and various soybean threshings are all had with the board-like threshing roll of adaptability
Cylinder.
To achieve the above object, the basic technical scheme of the board-like threshing cylinder of the present invention are as follows: including being connected in left and right fixation
Circular cross-section concave grate between dome lower part and the rotatable threshing roll being supported between left and right fixed dome, it is described de-
Grain rolling around the main board of rotation center equilateral triangle distribution mainly by constituting, and the one side of the board of the main board is by corresponding three
Extend the plate eaves of axially spaced-apart distribution perforation at angled peak, the rubber for continuing to extend is fixedly mounted by fastener in the plate eaves
Offset plate, the rubber slab have long slot hole corresponding with the perforation.
The present invention further improves, and the rubber slab is 70 ± 5HA, extension elongation with a thickness of 8-10mm, hardness
Range is 30mm-52mm.
The present invention further improves, and the plate face other side of the main board is bent into opposite with adjacent panels eaves and has
There are the clamping eaves of axially spaced-apart distribution perforation, the plate eaves and clamping eaves to pass through the fixed overhanging rubber slab of fastener clamp.
The present invention further improves, and the extension elongation of the rubber slab and plate eaves and clamps eaves clamping length difference
Than for 1:0.4-0.6.
In this way, rubber slab deformed when starting to touch beanpod it is small, have enough impact flailing action power, and then generate compared with
The carry of large deformation is sprung back, and is continued to generate in the high-speed rotation of threshing roll to brush and is hit flailing action, produces unexpected
Enhancing Threshing.
The present invention also further improve has:
It is serrated on the inside of the long slot hole of the rubber slab.
The concave grate is connected by the transverse slat of two sides, circular arc side plate and constitutes frame, the grating of immobilized preparation in the frame.

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.
The basic structure of the board-like threshing cylinder of the present embodiment is as shown in Figure 1, the left and right fixed dome 1,4 of annular passes through
Crossbeam 10 is connected, and the concave grate 9 of circular cross-section is fixed between the two lower part.Rotatable threshing roll 3 is turned by its rotation center
Axis 5 is supported between left and right fixed dome 1,4, and the drive pulley 7 of the outer end of shaft 5 and power input is connected.6 be that support turns
The bearing of axis 5.
Threshing roll 3 is as shown in Fig. 2, by two of main board 3-2 and equilateral triangle around the distribution of rotation center equilateral triangle
End plate soldering is constituted.The one side of the board of main board 3-2 extends axially spaced-apart distribution perforation by corresponding triangular apex
Plate eaves, the other side are then bent into opposite with adjacent panels eaves clamping eaves 3-3 also with axially spaced-apart distribution perforation, plate eaves and folder
It holds eaves 3-3 and the rubber slab 3-1 for continuing to extend is fixedly mounted by fastener clamp.
Rubber slab 3-1 is the key component for realizing ideal Threshing, and really up to the mark or too soft either percentage of damage is high or threshing is imitated
Fruit is bad, and the factors such as its flexibility and hardness, thickness, extension elongation (i.e. L2 in Fig. 2) are related, and applicant carried out depths thus
Enter research and repetition test, finally determined ideal rubber slab with a thickness of 9(± 1) mm, hardness be 70(± 5) HA, stretching
Length range is that 30mm-52mm(is adjustable according to soybean varieties, operating condition etc.).And in testing: when rubber slab extension elongation
Threshing when the ratio between L2 and plate eaves and clamping eaves clamping length difference L1 are 1:0.4-0.6 is even more ideal, application of tracing it to its cause
People's discovery, due to threshing roll direction of rotation be clamping eaves in preceding, plate eaves rear, and clamp eaves lower than plate eaves, as a result rubber slab is opened
Beginning deforms when touching soybean plant strain small, has enough impact flailing action power, and the carry for and then generating moderate finite deformation is sprung back,
Continue to generate in the high-speed rotation of threshing roll to brush and hit flailing action, to effectively enhance Threshing.
The specific structure is shown in FIG. 3 by rubber slab 3-1, has long slot hole corresponding with plate eaves and clamping eaves perforation, elongated slot
It is serrated on the inside of hole.It not only can be when rubber slab be clamped fixed, by the length surplus of strip hole, in certain model
It encloses and adjusts its extension elongation L2 on demand, to change cylinder-concave clearance when threshing roll work；And the sawtooth on the inside of long slot hole makes
There is " gear " sense when adjusting, and the frictional force with fixing bolt can be effectively increased, prevent threshing roll motion process rubber slab
Sliding, guarantees that the cylinder-concave clearance mixed up is constant always.
Concave grate 9 constitutes frame as shown in figure 4, transverse slat 9-1, the circular arc side plate 9-3 of two sides are connected, immobilized preparation in frame
Grating 9-2.
In addition, being inlaid in ring ladder groove of the present embodiment far from left fixed 1 outer end face of dome of power intake
Glass 8 is observed, and fixed by locking piece 2.The specific structure of locking piece 2 is as shown in figure 5, one end of its connecting plate 2-2 passes through
Locking bolt 2-1 is fixed on left 1 outer end face of fixed dome, and the other end pushes down observation by the locking pin 2-4 for being cased with rubber pad 2-3
Glass 8, so that it will not loosen to slide.Left fixed dome 1 using the structure of installation transparent observing glass among hollow out circular ring type with
Traditional closed threshing cylinder is compared, and can not only observe operation process Threshing, straw blockage situation etc., and simplicity can
The observation glass torn open can break down in threshing cylinder, card stalk or when need to adjust cylinder-concave clearance, pass through disassembly observation glass
Processing in time.
In use, mixing up suitable cylinder-concave clearance according to soybean varieties to be taken off, soybean plant strain to be taken off is above threshing cylinder
Feeding, external impetus are transferred to drive pulley 7, drive 3 unitary rotation of threshing roll to carry out threshing operations by shaft 5.After threshing
Soybean kernel fallen from the sieve pore of concave grate 9, stalk from drum front end export.
Experiments have shown that the present embodiment is compared to existing rigid threshing, not only rubber slab significantly reduces soybean threshing course
Fragmentation Phenomena, and threshing course soybean plant strain stress surface can be increased in the case where smaller hitting power using plank frame
Product, the effect of its " carry rebound " in addition, to significantly improve Threshing and threshing operations efficiency.
