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 utility model; 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 non-circular 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 non-circular gear 4 ＇, 4 respectively left and right flanges 2 ＇ by separately, 2 and frame be fixedly connected, be installed in non-circular gear 5 ＇, 5 in the middle of left and right on left and right jackshaft 6 ＇, 6 respectively with separately left and right center non-circular gear 4 ＇, 4 engagements, be installed on left and right planet axis 8 ＇, 8 left and right planet non-circular gear 7 ＇, 7 respectively with separately left and right in the middle of non-circular 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 non-circular gear, middle non-circular gear and planet non-circular gear three shaft gear planetary systems in the described left and right transmission case is arranged.As shown in Figure 4, right center non-circular gear 4 and right middle non-circular gear 5 engagements, non-circular gear 5 meshes with right lateral star non-circular gear 7 in the middle of the right side.
Center non-circular gear 4 ＇, 4, middle non-circular gear 5 ＇, 5, planet non-circular gear 7 ＇, 7 in the described left and right transmission case are non-round angular gear.
Center non-circular gear 4 ＇ in the described left and right transmission case, 4 and middle non-circular gear 5 ＇, 5 be non-round angular gear, planet non-circular gear 7 ＇, 7 are non-round straight-tooth gear.
Center non-circular gear 4 ＇ in the described left and right transmission case, 4 and middle non-circular gear 5 ＇, 5 be non-round spur gear, planet non-circular gear 7 ＇, 7 are non-round angular gear.
With middle non-circular gear 5 in the right transmission case and the relation of the installation between the planet non-circular gear 7, Fig. 5 is the schematic diagram of two staggered gears, 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 α angle is to decide with respect to the offset distance of seedling taking point according to the rice transplanting point of agriculture requirement.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 non-round helical gear with center non-circular gear, middle non-circular gear and planet non-circular gear is example, and operation principle of the present utility model is described:
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, the fixing non-round helical gear in center is tiltedly taken turns by the centre non-circle of non-round helical gear transmission planet, the helical gear helical angle rotation direction of non-circle is opposite with the center helical gear direction of non-circle wherein, and the helical gear helical angle rotation direction of the non-circle of planet is identical with the helical gear helical angle rotation direction of middle non-circle, 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, make institute's rice transplanting seedling line-spacing become width to change, 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 13 lifted through ascent stage of cams 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 transplanting rod 12 downward rapid movements, 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 non-circular gear and middle non-circular gear in the right transmission case are non-round angular gear, the planet non-circular gear is non-round spur gear, perhaps left, center non-circular gear and middle non-circular gear in the right transmission case are non-round spur gear, when the planet non-circular gear is non-round helical 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.
