Description

A kind of header of corn picker
Technical field
The utility model relates to a kind of corn picker, the header in particularly a kind of corn picker.
Background technology
Corn picker commonly used at present has large-scale and small-sized branch, and large-scale corn picker machine power is very big, and it is provided with header in the front of tractor and is used for winning the collection corncob, and the mechanism of crushing straw is arranged in the back of tractor operated by rotary motion.Small-sized corn picker also comprises dynamic power machine, walking machine and header and spike transporting conveyer.Grain header the place ahead is provided with branch ridge plate and dials standing grain mechanism, also is provided with on the header and plucks fringe pair roller, drop-down pair roller and crushed stalk mechanism, is provided with spike transporting conveyer in a side of plucking the fringe pair roller.The header of small-sized corn picker has only three branch ridge plates at most, and three branch ridge plates are formed two ridge stalk inlets.During corn picker work, the thumb wheel of dialling standing grain mechanism will enter two maize straws between the plate of branch ridge drag on pluck the fringe pair roller after, maize straw separates maize straw by the drop-down pair roller of plucking fringe pair roller and below with corncob, corncob reclaims by spike transporting conveyer, maize straw is then pulverized by the disintegrating mechanism of drop-down pair roller below, and stalk is pulverized also field, back.
Header mainly comprises branch ridge plate, dials standing grain mechanism, plucks fringe pair roller and transmission mechanism.The present standing grain mechanism of dialling mainly comprises thumb wheel and the transmission mechanism that drives the thumb wheel rotation, is arranged at intervals with the gear piece of dialling the standing grain sheet of stirring thumb wheel on the transmission mechanism; During work, the gear piece on the transmission mechanism is stirred the standing grain sheet is rotated thumb wheel, thereby stalk is screwed in the header rear.This kind structure more complicated, and the transmission between the power is soft transmission structures such as chain, cause disconnection easily, make dial the standing grain sheet can not normal rotation, when touching the bigger stalk of resistance or other fixtures in the field, for example be embedded in the underground backguy that is used for fixing electric pole etc., standing grain sheet, gear piece even the disconnected phenomenon of connecting gear support just can occur to dial, cause the grain header can't operate as normal.And in the course of the work,, often have stalk and be stuck between gear piece and group standing grain sheet, in the course of time, the stall phenomenon will inevitably take place, and then cause the driving chain support disconnected because the field divides the ridge irregular.
Transmission mechanism is generally soft transmission when carrying out power transmission, promptly common employing chain etc. transmits, this kind structure causes disconnection easily, adopt the rigidity transmission of output shaft form in addition, when this kind structure changes suddenly when speed, moment of torsion is also being followed rapidly and is being changed, and causes the output shaft fracture easily; And the length of transmission axle is wayward, when carrying out the assembly work of corn picker, transmission axle takes place easily cause the phenomenon that can't assemble because of error in length.
The front end contact of plucking the fringe pair roller is generally level and smooth setting, the rear end roll body normally directly is welded on deformed steel bar on the pair roller, this just makes corn picker when thumb wheel is stirred maize straw, only can lean on the power of stirring of thumb wheel that stalk is dragged on and pluck the fringe pair roller, thereby pluck fringe work; And owing to pluck the deformed steel bar of fringe pair roller is directly to be welded on the pair roller, and long-time use causes easily and comes off, and can't pluck fringe; Two rollers plucking the fringe pair roller are generally and be arranged in parallel, are unfavorable for the transmission of fruit ear.
