The stalk cutter has the characteristics of simple and reasonable structure and low noise, the vibration of a cutting table is slight, and service lives of machines are long.

Description

Hydraulic-driven double-pole bar reverse sync moves back and forth stem stalk cutter

Technical field

The utility model belongs to agricultural machinery, relates generally to a kind of rice wheat and cuts the ceding of Taiwan structure of shining on harvesting equipment and the combining facility.

Background technology

The stem stalk of used various rice and wheat harvester and combined harvester upper header moves back and forth cutter, no matter ceding of Taiwan swath is big or small, all is employed on one the whole knife bar riveting and adorns the knife section group.During operation, hydraulic-driven power drives from the end input of knife bar, and whole knife bar done straight reciprocating motion fast in the same way in the ceding of Taiwan, accomplish the cutting of stem stalk.Facts have proved that such structure inertia is big, vibration is big, and noise is big, is prone to cause mechanical failure, and facility are short service life, and working condition is poor.In recent years, along with the raising of China's harvest operation mechanization level, the harvesting equipment swath increases; The thickening of knife section size; Mechanically the crack requires to increase, and therefore cause the reciprocating vibration force of the ceding of Taiwan increases thereupon, and the problem reflection that the facility fault rate generally increases substantially is more outstanding.

Summary of the invention

The purpose of the utility model is exactly the problem that exists to above-mentioned prior art; Actual needs in conjunction with agricultural production; Design provides a kind of hydraulic-driven double-pole bar reverse sync of new construction to move back and forth stem stalk cutter, reaches the purpose that reduces the operation vibration, reduces facility fault rate and noise.

The basic design of the utility model is; Equipped respectively left knife bar and right knife bar on front portion, frame front beam left side and front portion, right side; Left side knife section group and right knife section group are packed in respectively on left knife bar and the right knife bar; Installing left knife bar drive seat and right knife bar drive seat on the left knife section group left part and on right knife section group right part respectively; Equipped cycloid hydraulic motor on the rear side position in the middle of the frame front beam, on the frame front beam, be positioned at cycloid hydraulic motor left side and place, position, right side be hinged respectively equipped left rocking arm and right rocking arm, left driving rod two ends are hinged with left knife bar drive seat and left rocking arm front end respectively; Right driving rod two ends are hinged with right knife bar drive seat and right rocking arm front end respectively; Cover is joined setting-up eccentricity shell type double link on cycloid hydraulic motor, and two interlinking lever ends of eccentric shell type double link are hinged with left rocking arm rearward end and right rocking arm rearward end respectively, protects and presses the sword nearside divider to be fitted on the frame front beam middle part; And left knife section group right-hand member and the adjacent spacing of right knife section group left end are blocked sealing, so far constitute hydraulic-driven double-pole bar reverse sync and move back and forth stem stalk cutter.

The utility model is employed in a left side and right two lever structures is set on the ceding of Taiwan left and right side; With cycloid hydraulic motor as driving power; Make the both sides knife bar do rightabout linear reciprocating motion synchronously during operation; Solved thoroughly that whole lever structure of the ceding of Taiwan and machine power drive the technical problem that exists in the prior art, had that structural design is simply new reasonable, ceding of Taiwan vibration is little, noise is low, the operation fault is few, the characteristics of facility long service life, especially be fit to the wide cut ceding of Taiwan and use.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of hydraulic-driven double-pole bar reverse sync moves back and forth stem stalk cutter; Equipped left respectively knife bar 4 and right knife bar 9 on front portion, frame front beam 2 left sides and front portion, right side; Left side knife section group 5 is packed in respectively on left knife bar 4 and the right knife bar 9 with right knife section group 7; Installing left knife bar drive seat 1 and right knife bar drive seat 10 on left knife section group 5 left parts and on right knife section group 7 right parts respectively; Equipped cycloid hydraulic motor 14 on rear side position in the middle of the frame front beam 2; On frame front beam 2, be positioned at cycloid hydraulic motor 14 left sides and position, right side place be hinged respectively equipped left rocking arm 13 and right rocking arm 11, left driving rod 3 two ends are hinged with left rocking arm 13 front ends with left knife bar drive seat 1 respectively, right driving rod 8 two ends are hinged with right rocking arm 11 front ends with right knife bar drive seat 10 respectively; Cover is joined setting-up eccentricity shell type double link 12 on cycloid hydraulic motor 14; Two interlinking lever ends of eccentric shell type double link 12 are hinged with left rocking arm 13 rearward end and right rocking arm 11 rearward end respectively, protect and press sword nearside divider 6 to be fitted on frame front beam 2 middle parts, and left knife section group 5 right-hand members and the adjacent spacing of right knife section group 7 left ends are blocked sealing.

During operation; The cycloid motion of cycloid hydraulic motor 14 is done reciprocally swinging in the opposite direction, that the amplitude of oscillation equates through eccentric shell type double link 12 driven in synchronism left side rocking arm 13 with right rocking arm 11 on frame front beam 2; Left side rocking arm 13 is through left driving rod 3, left knife bar drive seat 1 left knife bar 4 of driving and left knife section group 5 linear reciprocating motions; Synchronously; Right rocking arm 11 through right driving rod 8, right knife bar drive seat 10 drives right knife bars 9 and right knife section group 7 is accomplished and the reciprocal straight reciprocating motions of left knife section group 5 locking phases, completion ceding of Taiwan view picture stem stalk cutting operation.Protect and press in left knife section group 5 that sword nearside divider 6 sends into the stem stalk of frame front beam 2 left and right sides respectively left and right side and the right knife section group 7, avoid the stem stalk to get into a left side and right knife section group 5, between 7 in the spacing, cause ceding of Taiwan obstruction.
