Description
Technical field
The utility model relates to a kind of ear-snapping unit, more particularly, especially relates to the accurate chopping of a kind of engageable revolution three-roller type ear-snapping unit.
Background technology
Ear-snapping unit is the important workpiece of corn ear combined harvester, to the service behaviour of ear-snapping unit, has designed many outstanding technical schemes.At present; Known ear-snapping unit all is to adopt a pair of taper of rotation in opposite directions to draw the stem roller; This taper is drawn and is had six blades that are uniformly distributed along the circumference on the stem roller, or this taper draws and have spiral on the stem roller and pluck the fringe pawl, above drawing the stem roller the left and right fringe plate of plucking is set in this a pair of taper of rotation in opposite directions; Pluck left and right that planar horizontal is provided with rice-pulling chain on the fringe plate; In order when plucking fringe, to handle the stem stalk, what have is provided with the revolution cutting knife, the special outfit flail knife formula straw crushing and field-returning machine that has in this a pair of taper of rotation in opposite directions below drawing the stem roller.This technical scheme efficiently solve corn stem drop-down, pluck fringe and stalk and handle problems.But part still has some deficits: the technique scheme stalk is handled and is not reached the straw chopping and returning requirement, and no matter revolution cutting knife or flail knife formula straw crushing and field-returning machine are set, all can not be fully to stalk processing pulverizing; Power consumption simultaneously is big, and the requirement for dynamic balance of flail knife rotor is high, solves the bad reliability that will directly influence maize harvesting machine.
The utility model content
The purpose of the utility model is to the problems referred to above that exist, and provides that a kind of stalks cutting quality is good, energy efficient, the accurate three-roller type ear-snapping unit that shreds of engageable revolution that reliability is high.
For realizing above-mentioned purpose; The utility model adopts following technical proposals: the accurate chopping of the engageable revolution three-roller type ear-snapping unit of the utility model; Comprise transmission case and be installed in left socle, the right support on the transmission case; Fringe plate and right picking board are plucked in a left side that is installed in respectively on this left socle and the right support, and are horizontally set on two rice-pulling chains that plane on fringe plate and the right picking board is plucked on a left side respectively.Below plucking fringe plate and right picking board on a said left side; Be provided with respectively and draw the stem roller greatly and draw the stem roller for a short time, be positioned at this and draw the stem roller greatly and draw stem roller below that cutting roller is set for a short time, this draws the stem roller greatly, draws three roller center lines of stem roller, cutting roller to be the del configuration for a short time; And be parallel to each other and be installed in rotation on the transmission case; This draws stem roller spaced set impeller vertically for a short time, make the end face of adjacent two impellers constitute the circular turned opening, and the leaf wing of this impeller is consistent vertically; This draws the stem roller spaced set vane plate vertically that is uniformly distributed along the circumference greatly; Make the end face of adjacent two vane plates constitute the circular turned opening; And the circular turned opening that the circular turned opening that this impeller constitutes and this vane plate constitute is axially aligned; This cutting roller is the spaced set cylinder blade vertically; And in the circular turned opening that each cylinder blade radially is embedded into respectively in the corresponding circular turned opening that is made up of this impeller and be made up of this vane plate, each cylinder blade is meshed with adjacent impeller, vane plate simultaneously.
As the improvement of the utility model, said impeller is designed to four leaf wings; Saidly draw the stem roller to be uniformly distributed along the circumference greatly six groups of vane plates are set.
As the further improvement of the utility model, be positioned at said transmission case below, be symmetrical set two flail knives rotationally.
After adopting technique scheme, the beneficial effect that the accurate chopping of the engageable revolution three-roller type ear-snapping unit that the utility model provides has is:
Owing to below this draws the stem roller greatly and draws the stem roller for a short time, cutting roller is set; This cutting roller is the spaced set cylinder blade vertically; And in the circular turned opening that each cylinder blade radially is embedded into respectively in the corresponding circular turned opening that is made up of this impeller and be made up of this vane plate, each cylinder blade is meshed with adjacent impeller, vane plate simultaneously.During operation; Draw the stem roller greatly and draw the stem roller to be rotated down in opposite directions for a short time, the cylinder blade that is meshed with impeller, vane plate is simultaneously followed high speed rotating, and maize straw is drawn the stem roller greatly and draws the clamping of stem roller to push downward drawing for a short time; Cylinder blade is followed shredding corn stalk and is shed the field; Cutting disc is meshed with impeller, vane plate under the rotation status, and stationary knife is realized the precision chopping of maize straw each other, compares with traditional revolution cutting knife or flail knife; Power consumption is few, does not have the dynamic equilibrium problems of rotor in addition.Therefore, reached that the stalks cutting quality is good, energy efficient, effect that reliability is high.
