Abstract
The utility model discloses a cutter platform driving device of a harvester, which comprises a drive shaft, one end of the drive shaft is fixedly connected with a crank shaft which is vertical to the drive shaft, the crank shaft is connected to an eccentric shaft through a kinematic link, the kinematic link is in universal connection with the crank shaft and the eccentric shaft, the other end of the drive shaft is fixedly connected with the middle part of a dog driver which is vertical to the drive shaft, and the two ends of the dog driver are respectively provided with a cutter platform drive shaft which is respectively inserted into runners of drive boxes of an upper cutter platform and a lower platform, so as to toggle the upper cutter platform and the lower platform to do straight reciprocating motion. The cutter platform driving device of the harvester can drive the upper cutter platform and the lower platform synchronously, and the structure is simple.
Description
Technical field
The utility model relates to a kind of grain header, is the cutter platform transmission device of grain header specifically.
Background technology
Be used to gather in the grain header of paddy rice and wheat, have the upper slitter platform to be used to cut off spike of rice and the wheat head to deliver to sheller unit, also having down, the cutter platform is used for from the root certain altitude rice straw or wheat straw being cut off.The upper slitter platform of present grain header and following cutter platform respectively have a cover transmission device, with following cutter platform it is done reciprocating linear motion by stirring the upper slitter platform in the chute on the cutter platform driving shaft insertion cutter platform box respectively, adopt two cover transmission devices to make whole frame for movement more complicated, there was a mechanical failure easily, and increased the deadweight and the material cost of grain header.
The utility model content
The purpose of this utility model just is to provide a kind of harvesting machine knife platform transmission device, and this transmission device can drive upper slitter platform and following cutter platform simultaneously, and is simple and reasonable.
The utility model adopts following technical scheme: a kind of harvesting machine knife platform transmission device, comprise a power transmission shaft, power transmission shaft one end is fixedly connected with a perpendicular axle that turns, turning axle is connected on the eccentric shaft by kinematic link, kinematic link with described turn the axle and eccentric shaft adopt universal the connection, the power transmission shaft other end is fixedly connected on a perpendicular driving lever middle part, and described driving lever two ends respectively have a cutter platform driving shaft to insert respectively in the chute of the driving box on upper slitter platform and the following cutter platform to do reciprocating linear motion with following cutter platform to stir the upper slitter platform.
This harvesting machine knife platform transmission device of the present utility model, utilize the axle that turns of an eccentric shaft and connecting rod and transmission axle head, can do alternately rotating clockwise and counterclockwise of certain angle by the rotating drive power transmission shaft of eccentric shaft, the rotation of power transmission shaft makes that the driving rod of its end is that reciprocal arcuate movement is made in the center of circle with the axle center of power transmission shaft, thereby drives the upper slitter platform and following cutter platform is done linear reciprocating motion.The cutter platform moved simultaneously about this structure drove by a power transmission shaft, and simple in structure, therefore reliable equipment failure rate is low, and in light weight.
Description of drawings

Fig. 2 is the right view of harvesting machine knife platform transmission device shown in Figure 1.
Fig. 3 is turn clockwise the state diagram behind the certain angle of the driving shaft of harvesting machine knife platform transmission device shown in Figure 2.
Fig. 4 is the another kind of frame mode schematic diagram of eccentric shaft.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further, to help understanding content of the present utility model.
As Fig. 1 and Fig. 2, shown in Figure 3, it is harvesting machine knife platform transmission device of the present utility model, comprise a power transmission shaft 5, power transmission shaft 5 one ends are fixedly connected with a perpendicular axle 3 that turns, turn axle 3 and be connected one by driving shaft 13 by kinematic link 2, on the driving shaft 13 on fixing disk 12 and the disk on the eccentric shaft (axle is an eccentric structure for driving shaft 13 1 time) that constitutes with respect to the axle 1 of the axle center off-centre of driving shaft, kinematic link 2 is with eccentric shaft and turn axle employing universal joint syndeton, make kinematic link 2 and to turn axle and to rotate, by can be along its axial wobble in certain angle with eccentric shaft around its axle center.Power transmission shaft 5 other ends are fixedly connected on perpendicular driving lever 7 middle parts, and driving lever 7 two ends respectively have a cutter platform driving shaft 9,11 to insert respectively in the chute of the driving box 8,10 on following cutter platform 15 and the upper slitter platform 14.
As shown in Figure 1, when the work of grain header, eccentric shaft is driven in rotation, because kinematic link 2 is with eccentric shaft and turn axle and be the universal joint connected mode, so turning axle 3 by kinematic link 2 drives when the axle 1 of eccentric shaft rotates moves by making rotation direction around the axle center of power transmission shaft 2 clockwise and counterclockwise in certain angle, make power transmission shaft 2 also back and forth do clockwise and counterclockwise rotation direction motion around its axle center, then as shown in Figures 2 and 3, power transmission shaft 2 is made clockwise and counterclockwise rotation direction when moving moving in certain angle, the driving lever 7 of its end is also done synchronous clockwise and counterclockwise rotation direction motion, then the cutter platform driving shaft 9 and 11 at its two ends is done reciprocal movement in a curve, and because cutter platform driving shaft 9 and 11 is the driving boxes 8 that are inserted in down cutter platform and upper slitter platform respectively, in the vertical chute on 10, cutter platform driving shaft is merely able to sliding with corresponding cutter platform vertical direction upper edge chute, therefore can make upper slitter platform and following cutter platform make left and right sides linear reciprocating motion simultaneously by driving box, the vertical chute of determining that drives box have then absorbed driving rod at top offset easy for going up and down.
As shown in Figure 1 to Figure 3, two bearings 5,6 are housed, to be installed on the grain header on the power transmission shaft 2.Eccentric shaft also can adopt the structure of no disk as shown in Figure 4.
As shown in Figures 2 and 3, respectively there is a ball chamber at described kinematic link 2 two ends, described axle 1 end of turning axle 3 and eccentric shaft has bulb to be embedded in the ball chamber at described kinematic link 2 two ends respectively, and the opening in ball chamber in the length of the direction consistent with kinematic link greater than turning axle accordingly, the diameter of eccentric shaft, can swing certain angle around bulb to guarantee kinematic link, turn axle needs in the little displacement of its length direction when moving to adapt to, form a kind of gimbal structure, other existing gimbal structure be can certainly adopt, connecting rod and the universal syndeton that turns axle and eccentric shaft constituted.
