Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing and example.

[0012] Such as figure 1 As shown, the planetary carrier 2 is arranged in a "one" shape along its length direction to install five cylindrical gears meshing with each other, which are a crank planetary cylindrical gear 3, a planetary cylindrical gear 4, fixed cylindrical gear 5, and b planetary cylindrical gear 6 and b crank planetary cylindrical gear 7, O is the rotation center of the planet carrier 2, and the rotation centers of the remaining 4 cylindrical gears are O 2 , O 1 , O 3 , O 4 . The a crank 9 is consolidated with the a crank planetary spur gear 3, and the b crank 12 is consolidated with the b crank planetary spur gear 7. The a planting arm and the b planting arm are installed at the two ends of the planet carrier 2, the a planting arm 1, the a connecting rod 8, the a crank 9 and the O on the planet carrier 2 2 B 1 The straight line constitutes...

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 [0001] The invention relates to an agricultural machinery rice transplanter, in particular to a rotary double crank splitting mechanism. Background technique [0002] At present, the splitting mechanism of the high-speed rice transplanter adopts a rotary splitting mechanism, and its mechanical transmission mechanism has non-circular gears. The trajectory of the needle. The manufacture of non-circular gears is difficult, and the backlash of the teeth is large, which brings a lot of inconvenience to the design, manufacture and installation of the split mechanism. Contents of the invention [0003] In order to overcome the disadvantages of the existing rotary non-circular gear structure insertion and insertion mechanism, the present invention provides a rotary double crank insertion and insertion mechanism. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a rotary double crank splitting mechanism for ...
