Abstract

The invention discloses a combined incompletely eccentrically circular and non-circular gear planetary train vegetable seedling pick-up mechanism. An existing pick-up mechanism gains a wide-range variation in a transmission ratio of a pick-up trajectory through a locking arc and has high transmission impact. In the mechanism, a center shaft and a planet carrier are fixed; a central incompletely eccentrically circular gear is fixed to a frame, a central incompletely non-circular gear is fixed to the central incompletely eccentrically circular gear, and both the two gears loosely sleeve the center shaft; a first middle non-circular gear is connected with a first middle shaft through splines, and a first middle incompletely non-circular gear is fixed to a first middle non-circular gear; a second middle non-circular gear is connected with a second middle shaft through splines, and a second middle incompletely non-circular gear is fixed to the second middle non-circular gear; a first planet non-circular gear is connected with a first planet shaft through splines, and a second planet non-circular gear is connected with a second planet shaft through splines; both one end of a first planet shaft and one end of the second planet shaft are fixed to a shell of a pick-up claw. This mechanism has stable transmission and low impact.

Description

technical field

[0001] The invention belongs to the field of agricultural machinery, and relates to a vegetable seedling picking mechanism, in particular to a combined incomplete eccentric circle-noncircular gear planetary gear train vegetable seedling picking mechanism. Background technique

[0002] Transplanting has the comprehensive benefits of early crop growth and climate compensation. It can make full use of light and heat resources, and its economic and social benefits are very considerable. Potted seedling transplanting operations in paddy fields and dry land require the development of transplanting and seedling picking mechanisms.

[0003] The planetary gear train transmission mechanism has been used in the seedling picking mechanism of transplanting machinery. In order to complete the working process of picking seedlings-pushing seedlings-returning, the tip of the transplanting arm must complete the required motion trajectory. In the existing planetary gear The lo...

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] Such as figure 1 , 2 As shown in and 3, the combined incomplete eccentric circle-non-circular gear planetary gear train vegetable seedling picking mechanism includes a central shaft 1, a planet carrier 2, a central incomplete eccentric circular gear 3, a central incomplete non-circular gear 4, the first Intermediate shaft 5, second intermediate shaft 6, first intermediate non-circular gear 7, first intermediate incomplete non-circular gear 8, second intermediate non-circular gear 9, second intermediate incomplete non-circular gear 10, first planetary shaft 11. The second planetary shaft 12, the first planetary non-circular gear 13, the second planetary non-circular gear 14 and the seedling claw 15. One end of the central shaft 1 is connected to the power unit, and the other end is fixed to the planet carrier 2; the center incomplete eccentric circular gear 3 is fix...
