Description

Two moving knife reciprocating cutterbars

Technical field

The utility model belongs to agricultural machinery technological field, particularly a kind of two moving knife reciprocating cutterbars that are used on the full feeding rice wheat combine.

Background technology

At present, all use single action cutter reciprocating cutterbar on all feeding-in combine, its structure is the guard that some is installed on the cutter beam, and ledger-plate is all arranged on each guard, and tongue is protected on ledger-plate top, and guard body tip is used to lead standing grain.Moving knife bar and knife section are positioned at and protect the hypogloeeis.When knife section when ledger-plate is reciprocating, utilize ledger-plate and protect tongue and cut off crop as lateral support.The characteristics of single action cutter reciprocating cutterbar are only to need to drive one group of reciprocating getting final product of knife section, but in use it exists following weak point: the one,, owing to fix one group of knife section on the moving knife bar, its quality is big, the inertia force that work acts on the cutter driving mechanism when moving back and forth at a high speed is bigger, and can only make partial equilibrium, so machine vibration and wearing and tearing are bigger, very easily cause fault; The 2nd, because knife section moves, to decide moving plate and fix, average cutting speed is not high, if increase cutting speed, essential raising driving mechanism rotating speed, and the rotating speed increase further increases inertia, has therefore also limited raising machinery operation efficient.

In order to overcome the deficiency of using single action cutter reciprocating cutterbar on all feeding-in combine, adopting two moving knife reciprocating cutterbars is a kind of schemes.During work, two moving knife reciprocating cutterbars up and down moving knife do that speed is identical, stroke equates, direction moves back and forth the cutting crop on the contrary, therefore, its cutting speed is two times of single action cutter when stroke is identical, cutting speed is big, and the reciprocating motion inertia force that acts on the driving mechanism cancels out each other, therefore vibrate little, wearing and tearing less, fault is few.Two moving knife reciprocating cutterbars on half-feeding combine, have been adopted, the longitudinal supporting problem was solved by standing header nearside divider and pocket-wheel when it led standing grain problem and cutting, lateral support problem during cutting, because cut under the clamping of carrier chain on crop top, so the lateral support problem has also obtained solution.And on all feeding-in combine, have only straw shift wheel to make longitudinal supporting, therefore no lateral support is in the difficult problem of installing on all feeding-in combine that the existing two moving knife reciprocating cutterbars that adopted exist that crop is led standing grain, cuts the crop lateral support on half-feeding combine, connecting between two moving knife reciprocating cutterbar and the header.

Summary of the invention

The utility model is in the difficult problem of installing on all feeding-in combine that the existing two moving knife reciprocating cutterbars that adopted exist that crop is led standing grain, cuts the crop lateral support on half-feeding combine, connecting between two moving knife reciprocating cutterbar and the header, when a kind of cutting crop cane is provided, adopt straw shift wheel to do the two moving knife reciprocating cutterbars that use on all feeding-in combine of longitudinal supporting, to reach the purpose that improves cutting speed and balance reciprocating motion inertia force.

The technical scheme that two moving knife reciprocating cutterbar adopted that the utility model is used for feeding entirely on the combining device is finished in the following way: two moving knife reciprocating cutterbars comprise cutter beam, pressuring blade device, wearing piece, upper cutter, go up the moving knife bar, down knife section, down moving knife bar, guide, down moving knife bar positive stop strip, go up the moving knife slideway, go up the moving knife driving head, moving knife driving head, moving knife slideway, two moving knife drive unit, guide mounting rail, pressuring blade device pad down down.Wherein, cutter beam and header frame are linked together; Some knife sections quantitatively are fixed on the moving knife bar, and knife section is fixed on down on the moving knife bar under some quantity; Upper cutter pastes mutually with the working face of following knife section, and last moving knife bar and following moving knife bar are installed on the cutter beam, and pressuring blade device and pressuring blade device pad are fixed on the cutter beam, and wearing piece is fixed on the pressuring blade device and is pressed on the upper cutter; The leading flank of last moving knife bar leans on mutually with wearing piece, and the trailing flank of last moving knife bar leans on mutually with the pressuring blade device pad; The leading flank of following moving knife bar leans on mutually with following moving knife bar positive stop strip, and the trailing flank of following moving knife bar leans on mutually with the pressuring blade device pad; Guide is fixed on the guide beam by certain spacing, and the guide beam connects with cutter beam and frame; Last moving knife driving head and following moving knife driving head join with driving mechanism respectively, and last moving knife driving head and last moving knife bar join, and following moving knife driving head joins with following moving knife bar; Last moving knife slideway and following moving knife slideway are located on the cutter beam.

During work, move back and forth about last moving knife bar is done, two directions of motion about having, its forward and backward, upper and lower four directions of motion are spacing by facade, wearing piece lower plane and following knife section working face before facade, the pressuring blade device pad after the wearing piece respectively; Following moving knife bar moves back and forth about doing, and two directions of motion about having, its forward and backward, upper and lower four directions of motion are spacing by plane on facade, upper cutter working face and the cutter beam before facade, the pressuring blade device pad behind the following moving knife bar positive stop strip respectively.

The utility model provides a kind of pair of moving knife reciprocating cutterbar for all feeding-in combine, during use, the utility model improved greatly cutting speed and again balance reciprocating motion inertia force, compare with single action cutter reciprocating cutterbar, the utility model has also that vibration is little, wearing and tearing less, characteristics that fault is few.
