Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, shown in Figure 3, it comprises drive disk assembly and two left and right transplant arms that structure is identical; The left and right two ends of central shaft in the drive disk assembly are connected with the identical left and right transmission case of interior respectively, stretch out on the outer left and right planet axis of left and right transmission case left and right transplant arm is installed respectively.Left and right center eccentric gear 4 ＇, 4 are installed respectively in left and right transmission case 3 ＇, 3 of central shaft 1 left and right end, sky be enclosed within on the central shaft left and right center eccentric gear 4 ＇, 4 respectively by left and right flanges 2 ＇, 2 and frame be fixedly connected, be installed on left and right jackshaft 6 ＇, 6 middle eccentric modified gear 5 ＇, 5 respectively with separately left and right center eccentric gear 4 ＇, 4 engagements, be installed on left and right planet axis 8 ＇, 8 left and right planet eccentric gear 7 ＇, 7 respectively with separately left and right in the middle of eccentric modified gear 5 ＇, 5 engagements; Left and right planet axis 8 ＇, 8 and left and right jackshaft 6 ＇, 6 be crisscross arranged, left and right planet axis 8 ＇, 8 stretch out left and right transmission case 3 ＇, 3 external ends are fixed with left transplant arm, right transplant arm 9 respectively, during transplanting mechanism work, since left and right planet axis 8 ＇, 8 alternate angle cause left and right transplant arm seedling pin 10 after seedling taking relatively the seedling taking position be offset to the left or to the right, thereby realize that institute's rice transplanting seedling line-spacing width distributes.
The relative position triangularity in three axle center of center eccentric gear, middle eccentric modified gear and planet eccentric gear three shaft gear planetary systems in the described left and right transmission case is arranged.As shown in Figure 4, right center eccentric helical gear 4 and right middle eccentric displacement helical gear 5 engagements, eccentric displacement helical gear 5 meshes with right lateral star eccentric helical gear 7 in the middle of the right side.
Center eccentric gear 4 ＇ in the described left and right transmission case, 4 and planet eccentric gear 7 ＇, 7 be eccentric angular gear, middle eccentric modified gear 5 ＇, 5 are eccentric displacement angular gear.

Center eccentric gear 4 ＇, 4 in the described left and right transmission case are eccentric spur gear, and middle eccentric modified gear 5 ＇, 5 are eccentric displacement spur gear, and planet eccentric gear 7 ＇, 7 are eccentric helical gear.
As shown in Figure 5, with the gear in the right transmission case 5,7 is that example illustrates the installation relation between middle eccentric displacement helical gear 5 and the planet eccentric helical gear 7, the α angle is identical with the α angle among Fig. 2 among Fig. 5, be the alternate angle between jackshaft and planet axis, the utility model also utilizes the space rice transplanting track of this characteristics design transplanting mechanism just.As shown in Figure 6, the rice transplanting track 17 of left and right two transplanting mechanisms push away seedling point (rice shoot implant ground 18 location points) distance greater than seedling taking point apart from being seedling door 16 distances; As shown in Figure 7, the rice transplanting track 17 of left and right two transplanting mechanisms push away seedling point distance less than seedling taking point apart from being seedling door 16 distances.
Being helical gear with center eccentric gear, middle eccentric modified gear and planet eccentric gear is example, illustrates that operation principle of the present utility model is:
Transplanting mechanism power is delivered to the center sprocket wheel by rice transplanter chain-wheel box drive sprocket through chain, the drive central shaft rotates, driving left and right transmission case rotates, in the left and right transmission case that rotates, fixing center eccentric helical gear is by middle eccentric displacement helical gear transmission planet eccentric helical gear, the helical gear helical angle rotation direction of eccentric displacement is opposite with the direction of center eccentric helical gear wherein, and the helical angle rotation direction of planet eccentric helical gear is identical with the helical gear helical angle rotation direction of middle eccentric displacement, and the alternate angle that makes jackshaft and planet axis double helical angle is arranged.When planetary gear with planet axis when gearcase rotates, transplant arm rotates with planet axis, because the existence of alternate angle, the rotational plane of transplant arm and the rotational plane of gearcase are not parallel planes, the relative motion of transplant arm and gearcase involves to rotate and syntheticly makes that seedling pin track becomes a space curve on the transplant arm like this, make the seedling pin push away seedling and put relative seedling taking point (as shown in Figure 6) or (as shown in Figure 7) skew to the right left, when seedling door and the utility model transplanting mechanism all equidistantly distribute, thereby realize the narrow arrangement mode of line space one wide of rice transplanting.And the rotation of transplant arm forms one and affects shift fork 13 to be fixed on the transmission case around stationary cam 15() swing, shift fork lifted through ascent stage of cam 15 before seedling taking, and transplanting rod 12 is increased to peak, and compression simultaneously pushes away seedling spring 14; Before rice transplanting, the extreme higher position that shift fork 13 is in cam 15 keeps section in seedling taking; When the seedling pin 10 arrival rice transplanting positions that are fixed on the transplant arm housing 11, shift fork 13 goes to cam 15 breach, pushes away seedling spring 14 returns and promotes the downward rapid movement of transplanting rod, and rice shoot is pushed in the soil.Thereby order has been finished seedling taking, the rice transplanting action of rice seedling, realizes the capable transplanting of mechanization width of rice seedling.
Work as a left side, center eccentric gear in the right transmission case is eccentric angular gear, middle eccentric modified gear is eccentric displacement angular gear, the planet eccentric gear is eccentric straight-tooth gear, perhaps left, center eccentric gear in the right transmission case is eccentric straight-tooth gear, middle eccentric modified gear is eccentric displacement straight-tooth gear, when the planet eccentric gear is eccentric angular gear, because having alternate angle between jackshaft and planet axis equally arranges, therefore, seedling pin track still is a space curve on the transplant arm, making the seedling pin push away seedling puts relative seedling taking point and is offset to the left or to the right, when seedling door and the utility model transplanting mechanism all equidistantly distribute, still can satisfy the requirement of the capable rice transplanting of paddy rice width.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
