Description
Technical field
The utility model relates to agricultural machinery, especially a kind of two moving knife reciprocating cutterbar transmission cases that are used to reduce two moving knife reciprocating cutterbar volumes.
Background technology
At present, on harvester for both rice and wheat, all use single action cutter reciprocating cutterbar, 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 cutting blade; But in use; It exists following weak point: the one; Owing to fix one group of cutting blade on the moving knife bar; Its quality is big, and 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; Therefore machine vibration is bigger with wearing and tearing, very easily causes fault; The 2nd, because cutting blade 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 on harvester for both rice and wheat, using single action cutter reciprocating cutterbar, adopting two moving knife reciprocating cutterbars is a solution.During work; Two moving knife reciprocating cutterbars up and down moving knife do that speed is identical, stroke equates, reciprocating motion cutting crop in the opposite direction, 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.And the existing pair of moving knife reciprocating cutterbar be basically with in, the supporting use of large-scale combine; And its drive unit is installed in the one or both sides of working width; Adopt mechanism's realization reciprocating motions such as crank connecting link; Complicated when its version is installed to small farm machine, be unfavorable for arranging.
Summary of the invention
The utility model is to be solved to be exactly that existing two moving knife reciprocating cutterbar volume is big; Can't be installed in the problem of using on the small-sized farm implements; Provide a kind of volume little, be applicable to two moving knife reciprocating cutterbar transmission cases of the two moving knife reciprocating cutterbars of small-sized farm implements installation.
A kind of pair of moving knife reciprocating cutterbar transmission case of the utility model; Comprise casing, top link and swing arm down; It is characterized in that integrated power input shaft, bevel gear wheel, bevel pinion and eccentric stiffener assembly in the described casing; Power output shaft one end is that the spline form is connected with external power, and the other end is fixedlyed connected with the big vertebra gear; Bevel pinion is installed on the eccentric stiffener assembly, and meshes with bevel gear wheel; The eccentric stiffener assembly is connected respectively with top link, following swing arm, drives top link and moves reciprocatingly with following swing arm.
Described eccentric stiffener assembly comprises eccentric shaft, top link axle, following arm shaft, underarm and eccentric arm, and eccentric shaft and top link axle vertically are provided with, and are parallel to each other; The eccentric arm of upper and lower two levels is set on the eccentric shaft; The top link axle connects arm shaft and underarm down from top to bottom respectively, and following arm shaft and underarm are hinged through two eccentric arms of bearing pin and upper and lower setting respectively; Be provided with spline on top link axle and the following arm shaft, and be connected with top link, following swing arm respectively through spline.
Described transmission case casing front end end face is provided with four screwed holes, and transmission case is connected with cutter through screwed hole.
External power drives power input shaft through spline and rotates; Power input shaft go up hard-wired bevel gear wheel through it and the bevel pinion that meshes with bevel gear wheel with transmission of power to the eccentric shaft place; Drive the eccentric arm rotation of eccentric shaft and the upper and lower setting of eccentric shaft; Arm shaft was done reciprocal rotatablely moving under last eccentric arm was driven by bearing pin, and following eccentric arm drives underarm through bearing pin and rotates, and drives the top link axle with this and does reciprocal rotatablely moving; Arm shaft drove and moves reciprocatingly under top link was reached by the top link axle respectively with following swing arm, drove two moving knife reciprocating cutterbars with this and accomplished cutting work.
Two moving knife reciprocating cutterbar transmission cases of the utility model, compact conformation is convenient to connect; Can easily between small-sized farm implements and two moving knife reciprocating cutterbar, realize transmission agency, effectively reduce the volume of traditional double moving knife reciprocating cutterbar, be convenient to be installed on the small-sized farm implements and use; The kind of drive adopts the eccentric type transmission, makes things convenient for facility to connect, and reduces maintenance times; Utilization rate is provided, reduces production costs.
