Abstract
The utility model discloses a pot clamp type separating and transplanting mechanism of a double-crank rice pot seedling transplanting machine, belonging to agricultural machinery. A second elliptical gear, a first elliptical gear, a driven cylindrical gear, a diving cylindrical gear and a driving chain wheel are assembled in a gear box body; the driven cylindrical gear and the first elliptical gear are coaxially and fixedly arranged; the driving cylindrical gear and the driving chain wheel are coaxially and fixedly arranged; the driving cylindrical gear is engaged with the driven cylindrical gear; the first elliptical gear and the second elliptical gear are assembled and engaged according to a set angle; a driving crank shaft and a driven crank shaft are fixedly arranged at rotation center positions of the first elliptical gear and the second elliptical gear respectively; the two ends of the driving crank are fixedly connected with the driving crank shaft and a cam of a planting arm assembly according to the set angle respectively; one end of the driven crank shaft and the driven crank shaft are fixedly arranged, and the other end of the driven crank shaft is hinged with one end of a connecting rod; and the other end of the connecting rod is hinged with a crank of the planting arm assembly. The mechanism has the advantages of simple and rational structure, low manufacturing cost, capability of meeting pot seedling picking and transplanting operation requirements, good operation effect and high production efficiency.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to the hyperbolic spindle clamp alms bowl formula transplanting mechanism of the elliptic gear variable speed transmission on a kind of rice seedling transplanter.
Background technology
At present, China's rice transplanter research and development level has been in the first place in the world, but still has problems such as hindering root, seedling-slowing stage length.Accurate rice pot seedling transplant do not have slow seedling, the morning of tillering, raising the output, remarkably productive characteristics, be the planting patterns of paddy rice the best.
Existing rice seedling transplanter transplanting mechanism mainly contains and ejects and press from both sides the seedling dual mode.The eject-type operation is adopted planting or is lost the seedling mode in order, and the field is required height wholely, otherwise the operation quality of planting is difficult for guaranteeing; Folder seedling formula job requirements rice shoot is upright, and transport difficulty is big, is not with pulling seedlings device, and production efficiency is low.
Summary of the invention
The purpose of the invention is exactly the problem that exists to above-mentioned prior art; Design provides a kind of double-crank rice seedling transplanter folder alms bowl formula transplanting mechanism, reaches raising potted-seedling transplanting operating efficiency, guarantees plant operation quality, adaptation field condition and the strong purpose of rice shoot ability.
The purpose of the invention is achieved in that double-crank rice seedling transplanter folder alms bowl formula transplanting mechanism comprises the transplant arm assembly; Equipped second elliptic gear, first elliptic gear, passive roller gear, active roller gear and drive sprocket in gear housing; Described passive roller gear installs with first elliptic gear is coaxial; Initiatively roller gear installs with drive sprocket is coaxial; Initiatively roller gear and passive roller gear engagement, first elliptic gear and second elliptic gear install driving crank axle and driven crank axle by the equipped engagement of the initial angle of setting respectively in the pivot position of first elliptic gear and second elliptic gear; It is affixed that the cam of set angle and driving crank axle and transplant arm assembly is pressed at the driving crank two ends respectively; Driven crank one end is packed on the driven crank axle, and the other end is hinged by set angle and connecting rod one end, and the crank of the other end of connecting rod and transplant arm assembly is hinged.
The non-circular gear transmission mechanism is adopted in the invention; The variable speed transmission can make seedling taking folder cusp form " olecranon-like " track that satisfies the seedling taking angle; Also can satisfy simultaneously " kidney " type bottom trace of needs when rice transplanting; And the alms bowl body that the variable speed transmission can make the seedling taking folder accomplish rapidly in the gripping alms bowl dish hole carries out the seedling taking action; Guaranteed the traversing amount of seedling case and seedling dish, can satisfy the agriculture requirement of alms bowl dish shoot transplanting equipment, accurate rice pot seedling is transplanted and is not hindered root, slow seedling, the morning of tillering, raising the output; Help the raising of paddy rice yield per unit area, have modern design, simple and reasonable, cheap for manufacturing cost, low, adaptive capacity to field and rice shoot conditional request strong, meet that the alms bowl dish is got seedling and the job requirements of planting, operation effectiveness is good, production efficiency is high characteristics.

Embodiment
Below in conjunction with accompanying drawing the invention embodiment is described in detail.
Double-crank rice seedling transplanter folder alms bowl formula transplanting mechanism; Comprise transplant arm assembly 1; Equipped second elliptic gear 3, first elliptic gear 7, passive roller gear 9, initiatively roller gear 10 and drive sprocket 12 in gear housing 2; Described passive roller gear 9 and first elliptic gear, 7 coaxial installing, initiatively roller gear 10 and drive sprocket 12 coaxial installing, initiatively roller gear 10 and passive roller gear 9 engagements; First elliptic gear 10 and second elliptic gear 3 are by setting the equipped engagement of initial angle; Install driving crank axle 8 and driven crank axle 4 respectively in the pivot position of first elliptic gear 7 and second elliptic gear 3, it is affixed that the cam 14 of set angle and driving crank axle 8 and transplant arm assembly 1 press at the two ends of driving crank 13 respectively, and an end of driven crank 5 is packed on the driven crank axle 4; The other end of driven crank 5 is hinged by an end of set angle and connecting rod 6, and the crank 11 of the other end of connecting rod 6 and transplant arm assembly 1 is hinged.
During operation; Outer defeated power passes to first elliptic gear 7 by drive sprocket 12 through active roller gear 10, passive roller gear 9; Make first elliptic gear 7 and second elliptic gear 3 do the rightabout variable speed and rotatablely move, and driving crank 13, driven crank 5 are moved with the mode of variable speed transmission, the transplanting mechanism of the variable speed transmission driving transplant arm assembly 1 of driving and driven crank 13,5 forms specific " olecranon " shape movement locus when realizing folder alms bowl formula seedling taking gripping seedling; Bottom " kidney " type movement locus requirement when also satisfying rice transplanting simultaneously; The variable speed kind of drive of this mechanism makes seedling taking speed fast, meets the alms bowl dish and gets seedling and plant job requirements, and operation quality is good; Operating efficiency is high, and adaptive capacity is strong.
