Description
Technical field
The present invention relates to agricultural mechanical field, more particularly to a kind of Lysimachia sikokiana supporting with multiple roll sheller unit is crushed and is shed
Device.
Background technology
With the development of mechanization of agriculture, domestic by-products achieve the mechanization of results substantially, but in rural area, whenever
On the one hand harvest season receives grain Gui Cang, the process of one side stalk.Stalk treating method is generally burned, and is crushed, is filled or make compost,
But burning method meeting serious environment pollution, with the continuous improvement of people's environmental consciousness, environmental protection problem is increasingly subject to complete
The common concern of society, and the crop straw burning processing mode that to be also government department prohibite.And straw chopping and returning be then by
Field is shed after crushed stalk, is easy to directly cultivate, be a kind of processing mode of time saving and energy saving, convenient environmental protection again.
One kind disclosed in Chinese patent CN203691993U feeds threshing cylinder of grain combine harvester and its Lysimachia sikokiana entirely
Device, it increase Lysimachia sikokiana plate on threshing cylinder, and the threshing tine length on threshing unit is different.Chinese patent
Grass arranging device under a kind of united reaper disclosed in CN203801348U, it are arranged around wheel in the end of threshing cylinder, are passed through
The weeds such as stalk are discharged downwards by the guide plate on wheel with the Lysimachia sikokiana passage in 60 ° of directions of ground inclination.Although above scheme has
Effect improves operating efficiency, effectively prevents threshing cylinder from blocking, but crop stem is discharged along threshing cylinder tangential direction, discharge
The dispersion of distribution is limited to grass outlet width, and Lysimachia sikokiana fabric width can not be expanded, and easily causes local stalk and piles up.If in combining
Stalk crushing device is provided with machine threshing cylinder straw outlet, then parallel with the moving knife of pulverizer when stalk is discharged, cause stalk powder
Broken precision is relatively low, and power consumption is big, additionally easily causes that pulverizer partial load is excessive, and cutter utilization rate is low, it is impossible to meet big
Lysimachia sikokiana under the conditions of feed quantity is crushed and sheds demand.
Chinese patent CN202364588U proposes to weld stationary knife on threshing box, welds moving knife, Lysimachia sikokiana on threshing cylinder
Wheel and the scheme of threshing spike-tooth, are made stalk smash in threshing cylinder and be discharged it by tilting grass-removing wheel blade, and are taken off
Threshing tine length on grain part is different.Although this kind of grass arranging device improves Lysimachia sikokiana efficiency, it is possible to achieve the expansion of Lysimachia sikokiana fabric width
Exhibition, but the length of threshing cylinder is constrained to, moving knife and stationary knife arrangement limited amount in threshing cylinder, crop crush precision not
Height, can cause the crop stem that crushes entrance cleaning plant to increase cleaning load additionally, crop is crushed in threshing cylinder, it is impossible to
Meet the Lysimachia sikokiana under the conditions of big feed quantity and crush demand, and tilting swath board realizes that the extension of Lysimachia sikokiana fabric width is limited.
A kind of pulverizer suitable for self-propelled combine disclosed in Chinese patent CN204031820U, by setting
Having and coordinating the housing that installs with united reaper grass outlet, crushing knife assembly is loaded in housing, and guiding is provided with pulverizer
Plate is realized Lysimachia sikokiana over the ground and can uniformly shed crushing straw etc. being laid in ground, although this kind of scheme easy accessibility, and can realize
Stalk is discharged over the ground and is uniformly spread out, but, when entering pulverizer from the stalk that threshing cylinder is discharged, crop stem is put down with pulverizer
OK, the crushing precision of crop stem is not high, and the power consumption of pulverizer is larger, and the fabric width that stalk is discharged effectively can not extend.

304 can be monoblock type or segmented, and when curved surface swath board 304 is monoblock type, the quantity of curved surface swath board 304 is 2～6；
When curved surface swath board 304 is segmented, the quantity of curved surface swath board 304 is 4～12, and stair staggered is fixed on threshing unit
On 303.Curved surface swath board 304 is projected in 1/5～1/2 that the length on horizontal axial drum axle 302 is 3 overall length of horizontal axial drum.
In order to improve chopping result, drop lower powered loss, curved surface swath board 304 joins end to end the plane and transverse axis to be formed
The axis of stream roller axle 302 is in 0 °～20 ° angles, and the angle opening direction is to incline from Lysimachia sikokiana end to careless end is entered.
In conjunction with Fig. 1 and Fig. 2, the course of work is as follows：6 flow direction of crop stem as shown by the arrows in Figure 1, crop stem 6
First cylinder 1 is entered into by delivery chute (being not drawn in figure), is transported subsequently into second tin roller 2 and along 2 axial screw of second tin roller
Move and enter careless end to horizontal axial drum 3 and complete threshing course, the crop stem 6 for being basically completed threshing enters edge after horizontal axial drum 3
Its axis direction screw is to the further threshing of the grass-feeding end that is provided with curved surface swath board 304.Act in curved surface swath board 304
Under, crop stem 6 changes the direction of motion and dishes out uniformly, at a high speed along the normal direction of curved surface swath board 304, realizes that crop stem 6 is dished out
When distribution first time extension, crop stem 6 is tangential and be in θ with horizontal axial drum axle 302 along horizontal axial drum 3 is favoured
Angle is oblique to dish out.The first grass guide board 502 and second that crop stem 6 is inclined by after being dished out by 304 high speed of curved surface swath board again
Grass guide board 503 is divided into three straw cords and changes the direction of motion again realizes the extension of fabric width along dispersed the dishing out of careless base plate is gone out；
Enter after crushing scattering mechanism 4, contact in 90 ° of-θ with the moving knife for crushing scattering mechanism 4, realize sliding cutting, and the effect in moving knife
Under diagonally dish out again, realize second of fabric width extension, realize that full width width is shed.The axis of broken scattering mechanism 4 is less than horizontal stroke
Axis 440mm～the 670mm of axial-flow type drum 3.
In conjunction with Fig. 4 and Fig. 5, in order to preferably improve chopping result, reducing power consumption and and make crop stem 6 crush throwing
Spread dispersed on device, load is uniform, increased crushing and sheds effect, in first grass guide board 502 and the second grass guide board
A hinge hole and a mounting hole is each respectively equipped with 503, careless base plate is bolted on out, is existed by changing bolt
Position in mounting hole can change the angle of the first grass guide board 502 or the second grass guide board 503 and concave grate side wall 504.Institute
It is 0 °～20 ° that the first grass guide board 502 or the second grass guide board 503 are stated with the angle of concave grate side wall 504.Further, it is also possible to institute
