Abstract
The invention discloses a revolving double-crank transplanting mechanism of a seedling planting machine. A planet carrier rotates around the center of fixed cylindrical gears; a transplanting mechanism consisting of two double-crank mechanisms are mounted on the two ends of the planet carrier; the frame of the double-crank mechanisms is the planet carrier; the cranks of the double-crank mechanisms are driven to rotate by two cylindrical gears; the mechanism which is composed of the cylindrical gears and a plurality of member bars has no non-circular gears, thus realizing two seeding actions for one rotation around the planet carrier, and the track of seedlings meets the requirements of agricultural technology.
Description
Technical field
The present invention relates to the agricultural machinery rice transplanter, particularly relate to a kind of transplanting mechanism of rotary type double crank.
Background technology
At present, the transplanting mechanism of high-speed rice seedling planter is to adopt revolving transplanting mechanism, and non-garden gear is all arranged in its mechanical transmission mechanism, and its principle is to utilize the not uniform rotation of planet carrier and non-circular gear to realize the movement locus of seedling pin on the transplant arm.The manufacturing of non-circular gear is difficult, backlash is bigger, brings many inconvenience for design, manufacturing and the installation of transplanting mechanism.
Summary of the invention
For the deficiency of the transplanting mechanism that overcomes existing rotary non-garden gear structure, the invention provides a kind of transplanting mechanism of rotary type double crank.
In order to achieve the above object, the technical solution used in the present invention is: a kind of rice transplanter rotary type double crank insert division mechanism, and it comprises planet carrier, a crank planet roller gear, a planet roller gear, fixed cylinder gear, b planet roller gear, b crank planet roller gear, a transplant arm, a connecting rod, a crank, b transplant arm, b connecting rod, b crank; Wherein, described a crank planet roller gear, a planet roller gear, fixed cylinder gear, b planet roller gear, b crank planet roller gear are engaged with each other and become " one " word arrangement to be installed on the planet carrier, described a crank and a crank planet roller gear are fixed, and b crank and b crank planet roller gear are fixed.Described a transplant arm and b transplant arm are installed in the two ends of planet carrier.O on described a transplant arm, a connecting rod, a crank and the planet carrier

4B
2Section constitutes double-crank mechanism.
Further, also comprise seedling pin on a transplant arm that links to each other with a transplant arm with b transplant arm that the b transplant arm links to each other on the seedling pin.
The present invention compares with background technology, and the beneficial effect that has is:
1, do not have non-circular gear in the machine driving of transplanting mechanism, make and make and install simply;
2, whole transplanting mechanism is made up of simple roller gear and double-crank mechanism, and motion of mechanism and dynamic analysis are simple, less, the easy control in the gap of kinematic pair.

Embodiment
The invention will be further described below in conjunction with accompanying drawing and example.
As shown in Figure 1, planet carrier 2 is along becoming " one " word arrangement that 5 ground roller gears that are engaged with each other are installed on its length direction, be respectively a crank planet roller gear 3, a planet roller gear 4, fixed cylinder gear 5, b planet roller gear 6 and b crank planet roller gear 7, O is the center of rotation of planet carrier 2, and the center of rotation of all the other 4 garden stud wheels is respectively O

4Two rod members are quarter butt.Seedling pin 13 links to each other with a transplant arm 1 on a transplant arm, and seedling pin 14 links to each other with b transplant arm 10 on the b transplant arm.
During work, rotate at the center of planet carrier 2 fixed gear 5 in the middle of it, and a planet roller gear 4 rotates relative to planet carrier 2 under the drive of planet carrier 2 with b planet roller gear 6.A planet roller gear 4 drives a crank planet roller gear 3 rotations with its engagement again, thereby drive a crank 9 rotates, and drives 1 rotation of a transplant arm by a connecting rod 8, thus seedling pin 13 motions on a transplant arm that drive a transplant arm 1 links to each other; The b crank planet roller gear 7 that b planet roller gear 6 drives again with its engagement rotates, rotate thereby drive b crank 12, and drive b transplant arms 10 by b connecting rod 11 and rotate, thereby drive with b transplant arm that b transplant arm 10 links to each other on seedling pin 14 move.
The movement locus of a seedling pin 13 of a transplant arm 1 and the b seedling pin 14 of b transplant arm 10 is by the rotation of planet carrier 2 and two a cranks 9 and b crank 12, and the resultant motion that drives the rotation of a transplant arms 1 and b transplant arm 10 by a connecting rod 8 and b connecting rod 11 obtains.
The foregoing description is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
