Abstract

The utility model relates to a header assembly of a low vibrating harvester. The utility model comprises a spiral propeller, a cutting knife toothed rod which is distributed with tooth-shaped blades, a pushing and transporting toothed rod which is distributed with pushing and transporting teeth, and a swing rod which is provided with an eccentric shaft, wherein both sides of the swing ring are respectively connected with an inner rotary shaft and an outer sleeve pipe respectively through a connecting rod, and the cutting knife toothed rod and the pushing and transporting toothed rod are respectively connected with the inner rotary shaft or the outer sleeve pipe through respective swing arms. When the swing ring passes through the eccentric shaft to rotate and generate swing, the inner rotary shaft and the outer sleeve pipe are oppositely driven to rotate to and fro, the cutting knife toothed rod and the pushing and transporting toothed rod are driven by a cutting knife swing arm and a pushing and transporting swing arm to move repeatedly and oppositely, and thus, periodical driving force which is additionally added on a header is reduced or eliminated, motion inertia of the cutting knife toothed rod and the pushing and transporting toothed rod is counteracted mutually, and vibrations of the header are reduced.

Description

Low vibration harvester header assembly

Technical field

The utility model relates to a kind of low vibration harvester header assembly, belongs to agricultural machinery.

Background technology

Grain header is to be used to gather in paddy rice, the harvesting machinery of crops such as wheat, ceding of Taiwan assembly is the assembly of the main function components of grain header, it comprises cutter knife mechanism, push mechanism, spiral propeller and pendulum ring transmission executing agency, cutter knife mechanism and push mechanism simultaneously with the swing of pendulum ring, the direction and the hunting frequency that are the two reciprocally swinging are identical, the two produces periodic driving force to the ceding of Taiwan in high-speed synchronous in the process that moves back and forth, when this driving frequency that the adds frequency intrinsic with posting the ceding of Taiwan is identical, the amplitude of the ceding of Taiwan reaches maximum, resonance promptly appears, fierce vibration takes place in ceding of Taiwan this moment, powerful vibration force often makes the securing member of the ceding of Taiwan loosening, weld cracking, even parts fracture, parts can not run well, people can only adopt the increasing securing member for this reason, the method of reinforcement of weld, to avoid or to reduce to vibrate the damage that brings to machinery, but this is helpless way, it can not solve the bad working environments that the ceding of Taiwan is worked at all under the fierceness vibration, even the situation that complete machine can't be worked can occur.

Summary of the invention

The purpose of this utility model provides a kind of low vibration harvester header assembly, and it is by reasonably design, the outer periodicity driving force that is added on the ceding of Taiwan is weakened or eliminates the vibration of the reduction ceding of Taiwan.

The utility model harvester header assembly contains cutter knife mechanism, push mechanism, spiral propeller and pendulum ring transmission executing agency, wherein, cutter knife mechanism comprises the cutter ratch of flute profile blade and fixed blade, push mechanism and comprise the ratch that pushes that pushes tooth and fix this tooth, pendulum ring transmission executing agency comprises to be provided with puts ring, the execution rotating shaft that links to each other with the pendulum ring, with push the cutter swing arm that pushes swing arm and link to each other that ratch links to each other with the cutter ratch, feature of the present utility model is rotating shaft and an outer tube in said execution rotating shaft comprises, said pendulum ring each side links to each other with outer tube with interior rotating shaft respectively by a link rod, and the said upper end that pushes swing arm and cutter swing arm is connected respectively with interior rotating shaft or outer tube.Pendulum is equipped with eccentric shaft and central axle sleeve, and the main shaft of spiral propeller links to each other with pendulum ring eccentric shaft by drive disk assembly.

Rotating shaft or outer tube link with the left and right sides of pendulum ring respectively in above-mentioned, because the swaying direction of the pendulum ring left and right sides is opposite, therefore rotating shaft or outer tube reverse rotation each other in, the scheme of rotating shaft or outer tube in the utility model has adopted and will push swing arm and the cutter swing arm is connected respectively, make the swing that pushes swing arm and cutter swing arm opposite, cause the direction of motion that pushes ratch and cutter ratch opposite, the two alternately moves back and forth, their movement inertia is cancelled each other, the periodicity driving force that is added in the ceding of Taiwan is weakened or eliminate, reach the purpose that reduces ceding of Taiwan vibration.

Description of drawings

Fig. 1 is the example structure schematic diagram of the utility model ceding of Taiwan assembly.

Fig. 2 is that the E of Fig. 1 is to view.

Fig. 3 is that pendulum encircles the F of executing agency to view among Fig. 2.

Each label of above accompanying drawing is expressed as follows:

The pendulum ring, 2-interior rotating shaft, 3-outer tube, 3-1-, 4-push swing arm, 4-1-push swing arm lower end yoke, 4-2-push swing arm upper end adapter sleeve, the swing arm of 5-cutter, 5-1-cutter swing arm lower end yoke, 5-2-cutter swing arm upper end adapter sleeve, 6-cutter ratch, 6-1-cutter link rod, 7-push ratch, 7-1-push link rod, 8-flute profile blade, 9-push tooth, 10-pulley transmission mechanism, 11-header frame, 12-spiral propeller, 13,14-be respectively the left and right sides link rod of pendulum ring, 15-pendulum ring eccentric shaft, 16-pendulum ring central axle sleeve.

Embodiment

As shown in Figure 1, spiral propeller 12 and push ratch 6, cutter ratch 7 is installed on the frame 11, the eccentric shaft 15 of the rotating shaft of spiral propeller 12 by pulley transmission mechanism 10 and pendulum ring 1 link to each other (referring to Fig. 2 and Fig. 3); Push ratch 6 and be distributed with and push helical teeth 9, cutter ratch 6 is distributed with flute profile blade 8; Push ratch 7 and cutter ratch 6 respectively by push link rod 7-1 and cutter link rod 6-1 and push swing arm 4, cutter swing arm 5 links to each other, push swing arm 4 and be connected with outer tube 3 with interior rotating shaft 2 respectively, interior rotating shaft 3 and outer tube 3 and pendulum ring 1 link to each other (referring to Fig. 3) with cutter swing arm 5 upper ends.

As shown in Figure 2, pendulum ring 1 is provided with central axle sleeve 16, is provided with eccentric shaft 15 in the cover, and when eccentric shaft was rotated by belt pulley 10 transmissions, pendulum ring 1 was promptly swung.

Fig. 3 shows that the left and right sides of pendulum ring 1 is connected with interior rotating shaft 2 and outer tube 3 respectively with 14 by link rod 13, when pendulum ring 1 swings back and forth, interior rotating shaft and outer tube are promptly rotated back and forth by drive, because the swaying direction of the left and right sides of pendulum ring 1 is opposite, the rotation of therefore interior rotating shaft 2 and outer tube 3 is opposite; The upper end that pushes swing arm 4 links to each other with outer tube 3 with adapter sleeve 4-2, the lower end with yoke 4-1 with to push link rod 7-1 hinged; The upper end of cutter swing arm 5 links to each other with interior rotating shaft 2 with adapter sleeve 5-2, and the lower end is hinged and connected with cutter yoke 5-1 and cutter link rod 6-1.

This ceding of Taiwan assembly push ratch 6 and cutter ratch 7 produces reverse each other reciprocating motion with the rotation of interior rotating shaft 2 and outer tube 3 respectively by pushing swing arm 4 and cutter swing arm 5, be among Fig. 1 cutter ratch 6 to left movement, shear the crop cane by flute profile cutter 8, simultaneously, push ratch 7 and move right, helical teeth 9 pushes the crop of cutting forward, vice versa, the two alternately moves back and forth, and their movement inertia is cancelled each other, thereby reaches the purpose that reduces ceding of Taiwan vibration.
