Description
Technical field
The present invention relates to a kind of flexible grain threshing devices, belong to agricultural machinery technological field.
Background technique
Grain threshing is as the core component in crop harvester and thresing machine, harvest product of the threshing performance to crop
The safe storage in matter and later period has important influence.Cropper and thresing machine most at present all uses rasp bar formula or plate tooth
Formula sheller unit, although it has the characteristics that threshing efficiency is high, since its threshing unit is high speed rigid contact, so
Cause the percentage of damage of seed more, so as to cause the rising of seed damage rate, especially to the moisture content higher cereal problem table
It is existing particularly pertinent.Secondly as threshing of axial unit with axial feeding there is also feeding process by conversion tangentially in the axial direction, so working as paddy
When object feeding is uneven or larger, the blockage problem of threshing cylinder entrance is often shown, thresing machine or cropper are seriously affected
The functional reliability of threshing system, for this purpose, developing the flexibility grain threshing device.
Summary of the invention
According to the above-mentioned deficiencies in the prior art, the problem to be solved in the present invention is: it is simple to provide a kind of structure, and design is closed
Reason can be improved Threshing, reduce the flexible grain threshing device of seed damage rate.
The technical solution adopted by the present invention to solve the technical problems is:
The flexible grain threshing device, including rack threshing cylinder are arranged in rack, above threshing cylinder in setting
Bolter, bolter sealed set upper housing on the outside in correspondence are arranged concave grate below threshing cylinder, threshing cylinder, recessed
Screen, upper bolter and upper housing are each attached in rack.
Flexible grain threshing device can effectively prevent occurring in threshing course by the cooperation of upper bolter and concave grate
Clogging improves threshing efficiency, while cooperating threshing cylinder that can easily carry out grain threshing, and structure is simple, and design is closed
Reason has stronger practicability.
Further preferred, upper bolter includes stamped sieve and deflector, and along axial direction, helically the distribution of line shape welds deflector
It connects on stamped sieve, helix angle is 68-78 °, and the sieve pore on stamped sieve is in long trough, and its orientation and deflector are flat
Row.When cereal takes top to by threshing cylinder, the setting of deflector can carry out water conservancy diversion to cereal, improve grain stream movement
Smoothness and improvement later period Threshing.
It is further preferably, the setting of deflector uniform pitch, and the height of deflector along threshing cylinder rotation direction gradually
Increase.The design that deflector gradually increases can effectively prevent cereal to block on detachment roller top, improve threshing effect
Rate.
Further preferably concave grate includes Turbogrid plates and steel wire, and 4-6 root is arranged in Turbogrid plates, and 4-6 root Turbogrid plates are along threshing
It the axial direction of roller and is distributed perpendicular to steel wire, steel wire is uniformly distributed along the circumferencial direction that threshing cylinder rotate, and interval is greater than seed
The maximum length 1-3mm of grain.The cooperation of Turbogrid plates and steel wire, since space increases, obtains cereal when cereal turns over Turbogrid plates
Fluffy chance is obtained once, is separated so that the seed taken off be made to more easily pass concave grate, grain threshing efficiency is improved.
Further preferred, Turbogrid plates are higher by steel wire 30mm-40mm.The preferably separation of cooperation seed.
Further preferred, arranging plate tooth and elastic threshing unit on threshing cylinder, plate tooth crest is equipped with hangs down with its top margin
Straight tooth-shape structure, plate tooth and elastic threshing unit are arranged 4-8 and are in that the axis angle of installation site and threshing cylinder is
35-75°.Plate tooth helically the distribution of line shape and use trapezium structure, the blocking of threshing cylinder entrance, while threshing section can be prevented
Using elastic threshing unit, the rubbing effect to crops can not only be improved, and can reduce the percentage of damage of seed.Threshing
Roller is welded with 4-8 head plate tooth in front according to its diameter, and plate tooth and threshing cylinder axis are in 45-75 °, and plate tooth is along threshing cylinder
Axis direction shares 3 rows, and the plate tooth height is gradually reduced along the circumferencial direction that threshing cylinder rotates.Threshing cylinder is according to it
Diameter is equipped with 6-8 and with threshing cylinder axis at 40-60 ° of elastic threshing unit at rear portion.
Further preferred, the arrangement screw pitch of elastic threshing unit is 3-5 times of plate gear mutation screw pitch.Prevent the hair of blocking
It is raw, improve threshing efficiency.
Further preferred, one end of elastic threshing unit welds or is connected to threshing cylinder using screw connecting mode
On, the other end of elastic threshing unit is hanging, and elastic threshing unit surface is equipped with threshing cylinder axis angle is 25-35 °,
Spacing is the helicitic texture of 5-10mm.
Further preferred, one end of elastic threshing unit is welded on threshing cylinder, and other end moveable support is in threshing
The outer surface of roller.
Further preferred, elastic threshing unit one end connects hinged seat, and the other end of elastic threshing unit is hanging, hingedly
Seat is welded on the surface of threshing cylinder, and torsional spring is arranged on the inside of hinged seat, and torsional spring and elastic threshing unit are mounted on hinge by pin shaft
On joint chair.
Elastic threshing unit using front and threshing cylinder weld perhaps with pin shaft be articulated and connected rear portion be in vacantly or
The elastic outer surface for being movably pressed in threshing cylinder, makes it together with the Turbogrid plates on concave grate, the deflector on upper bolter, complete
At the threshing of cereal.
The present invention has the beneficial effects that
1, flexible grain threshing device of the present invention above threshing cylinder by being arranged the upper separation with deflector
Sieve can carry out effective water conservancy diversion to the cereal for reaching top, avoid blocking in threshing course, improve the threshing effect in later period
Fruit.
