Description
Technical field
The invention belongs to agricultural machinery technological field, more particularly to a kind of longitudinal axial flow united reaper.
Background technology
At present, under the driving of the factors such as national policy guiding, country labor force transfer, domestic land transformation speed is accelerated,
Single block area increases, and wide paths for tractors in the countryside broadens, the continuous improvement of crops per mu yield.User wants to united reaper operating efficiency
Seek more and more higher.
Central Plains region at home, crop-planting situation are：Wheat and Corn Rotation System, wheat and soybean crop rotation, wheat and water
Rice crop rotation.User generally wishes that united reaper does not have to change or change less parts substantially, only carries out roller speed governing can
Wheat can not only be zoomed in, moreover it is possible to take in soybean, rice, seeding corn and other crops concurrently.But main flow united reaper is difficult to the above at present
Function, take in concurrently reluctantly, harvest effect is undesirable, is mainly shown as that percentage of damage is high, entrainment loss is big, operating efficiency is relatively low.
On the other hand, user requires more and more higher to united reaper rate of return on investment, and the harvest of simple single cropping crop is
The requirement of user's income can not be met.
The main flow united reaper in Central Plains market is " cutting stream+transverse-axis-flow " machine of single horizontal axial drum or one and half rollers
Type, its threshing cylinder landscape configuration, crop enter from roller one end, are discharged from the other end.Because complete machine structure limits, transverse-axis-flow
Roller can not be oversize, and otherwise complete machine width is too big.Such type threshing and separating capacity are restricted, and harvest wheat feed quantity is dashed forward
Broken 5 ㎏/s difficulty is larger, causes machine operation efficiency to meet user's request.When particularly harvesting moist wheat, entrainment damage
Lose greatly, roller easily blocks, and machine operation is less efficient.In the market also has double transverse-axis-flow roller type, but type harvest is dry
During dry wheat, emersion object is more, and cleaning load is big, and operating efficiency is equally relatively low.
In addition, being required according to national legislation, united reaper should match somebody with somebody straw chopper, to realize straw-returning, and it is current
" transverse-axis-flow " type matches somebody with somebody straw chopper chopping result and particularly shreds that rice straw effect is unsatisfactory, and major defect is stem
Stalk is oversize after shredding, it is too narrow etc. to shed breadth.
A kind of in addition, full feed type joint of wheels travel formula disclosed in Chinese utility model patent ZL201320484653.2
The full feed type combine harvester of wheels travel formula disclosed in harvester and Chinese utility model patent ZL201320484703.7,
Its essence is a kind of single longitudinal axial flow united reaper, the engine arrangement of the type is led in the side of single longitudinal axial flow release unit
The defects of cause is the cleaning room restricted width in the case of complete machine restricted width, clean area deficiency, cause operating efficiency compared with
It is low.It is poor to the adaptability of crop varieties and the type roller can not realize stepless speed regulation.
At present, another single longitudinal axial flow united reaper of in the market, the extra configuration of straw chopper make in machine afterbody
Machine length of wagon is obtained to lengthen.And the type, which can not be realized, easily changes notch board, poor to the adaptability of crop varieties.
The content of the invention

Cylinder emersion object makes emersion object uniform on cleaning plant, cleaning loss is small to the middle guide of the cleaning plant.
Because the bottom of the stalk outlet is provided with slide plate, the stalk of discharge is smoothly slided to the cane by slide plate and shred
Device.
Because the type shredder includes the movable arbor by actuator drives, the axial direction of the movable arbor is transversely set
Put, some moving knife are distributed with the movable arbor, thus moving knife direction of rotation and longitudinal axial flow roller direction of rotation are inconsistent, favorably
In straw chopping, straw chopping length meets stalk returning to the field needs, can perfuse whole swath, will not cause became uneven；Due to
The type shredder also includes chopper cover and sheds device, and the upper end for shedding device is articulated with the bottom of the chopper cover
Portion；Stopping means is provided between the threshing body shed above device and the type shredder, when cleaning plant is tieed up
When repairing, make to shed device by stopping means and be in recovery state, shed device and surround moving knife together with stationary knife support, play peace
Full protection acts on；When machine is transported, also make to shed device by stopping means and be in recovery state, fuselage is short, is easy to transport；When
During machine operation, make to shed device by stopping means and be in and shed state.
Due to the row's of being formed chaff passage, the threshing body afterbody between the stationary knife support and the tail sheet of the cleaning plant
Both sides are respectively equipped with auxiliary row's chaff mouth at the upper screen box of the cleaning plant so that cleaning loss is small, and seed cleannes are high.
Because the both ends of the tail sheet are equipped with the antennular plate for stretching into the auxiliary and arranging chaff mouth, the antennular plate extends to institute
The outside of threshing body is stated, when antennular plate moves with tail sheet, can play a part of preventing auxiliary row's chaff mouth from being blocked by chaff.
Drum drive case and stepless speed change device due to the propulsion plants design, thus by stepless speed change device and
Drum drive case ensures that installed threshing separator carries out effective threshing separation to various crop.
