Between the ram assembly and the cam 13, supported on the right fixed plate 6 and the left fixed plate 14 and the mechanism On the stationary lever shaft 9 parallel to the mandrel 1, a row of levers 10 acting on the jack by a cam is provided; the end of the lever 10 away from the lever shaft 9 is provided with a projection on a side facing the jack 21, and the lever 10 is close to the lever shaft. One end of the pin 9 is provided with a projection on the side facing the cam 13, and the movable end of the lever 10 is placed on the other side of the retaining shaft 11 which is fixedly supported by the left and right fixing plates 14, 6 in parallel with the lever shaft 9.

The ejector pins are evenly distributed in the axial direction corresponding to the cams 13, and are uniformly distributed in the circumferential direction at a certain angle N. The seedlings in each row falling into the same row in the field are successively ejected to ensure equal spacing. When the cam 13 rotates, the protrusion of the end of the lever 10 is actuated, the lever 10 is pushed to swing about its axis 9, and the protrusion of the other end pushes the ejector pin 21 to compress the spring 29 to wrap the rice in the bowl of the bowl on the rotating cage. The seedlings are topped out, and the seedlings fall into the field along the guiding seedling tube to complete the orderly transplanting operation. Preferably, the bottom of the bowl (30) is provided with a "plum" type slit 31 to enhance the seedling ejection effect.

3) The disc replica mechanism comprises: a rotating "star" shaped replica wheel 25 at the position between the lower rear side of the cage and the guide tube; the "finger" tooth rotates to the same direction In the empty bowl of the cage rotating the disc, the bowl of the bowl deformed by the ejector 21 is restored to its original state.

4) The automatic disc separation mechanism comprises: under the outer part of the cage, at the front lower position of the replica wheel 25, a disc separation stopper 26 fixed on the frame is arranged, and the empty disc falling from the cage is touched. After the block 26, that is, it slides down along the block 26, and at the same time, due to the support blocking action of the block 26, the buckles on the trays which are originally coincidently connected are separated, and the lower tray is detached from the frame. Recycled in the tray.

The cam 13 and the turntable are rotated at a certain speed ratio, and the direction of rotation is related to the transmission mechanism in the transmission case 3.

If the transmission box 3 is a three-axis transmission transmission box, there is one input rotation, the coaxial reverse output of the two large transmission ratios rotates, the high-speed central shaft 1 drives the cam 13 to rotate, and the low-speed output drives the rotating cage to rotate, and the two turn oppositely. The lever mechanism is disposed in the lower left portion of the cage, and the free end of the lever 10 is inverted on the lever shaft 9. As shown in Figures 9 and 10, in the transmission case, the first pinion gear 3-8 fixed to the center shaft 1 is meshed with the first large gear 3-7 fixed to the first intermediate shaft 3-2, and is fixed at the first The second pinion gear 3 - 3 on the intermediate shaft 3 - 2 meshes with the second large gear 3 - 4 fixed to the second intermediate shaft 3 - 5 , and the third pinion gear fixed to the second intermediate shaft 3 - 5 3-6 is engaged with the third large gear 3-1 of the sliding sleeve on the central shaft 1, and the third large gear 3-1 extends out of the sleeve at the outer end of the transmission box and is fixedly connected with the rotating cage, and the cam 13 and the cymbal cage Turning the opposite, as shown in Fig. 1, the free end of the lever 10 is inverted on the lever shaft 9. If the transmission box 3 is a four-axis transmission transmission box, there is one input rotation, the coaxial transmission of the two large transmission ratios is in the same direction, the high-speed central shaft 1 drives the cam 13 to rotate, the low-speed output drives the rotation of the cage, and the lever mechanism is set at the rotation. In the upper left part of the cage, the free end of the lever 10 is supported downward on the lever shaft 9. As shown in Figures 11, 12 and 13, in the transmission case, the first pinion gear 3-19 fixed to the center shaft 1 is meshed with the first large gear 3-18 fixed to the first intermediate shaft 3-10, and is fixed at The second pinion gear 3-11 on the first intermediate shaft 3-10 meshes with the second large gear 3-12 fixed to the second intermediate shaft 3-13, and is fixed to the third intermediate shaft 3-13 The pinion gears 3-17 are meshed with the third large gears 3-16 fixed to the third intermediate shaft 3-15, and the fourth pinion gears 3-14 fixed to the third intermediate shaft 3-15 and the sliding sleeve are at the central axis The fourth large gear 3-9 is engaged with the fourth large gear 3-9, and the sleeve extending from the outer end of the transmission box is fixedly connected with the rotating cage, and the cam 13 is turned in the same direction as the tray rotating cage, as shown in FIG. The free end of the lever 10 is supported downward on the lever shaft 9.

During operation, the second drive sprocket 17 drives the transport roller 18 to drive the conveyor belt 16 and the sling plate thereon, and feeds the platform 19 through a boring plate flush with the conveyor belt 16, which is driven by the transmission case 3. Rotating and rotating together, the conveying roller is slightly faster than the rotating cage, so that the conveyor belt has a forward pushing effect on the boring plate, which can be smoothly and accurately wound onto the rotating cage; 16 fixed on the central shaft 1 The cams are divided into two groups and are driven by the transmission sprocket to rotate at a constant speed. The eight cams in each group push the corresponding levers in turn, and the corresponding ejector pins are sequentially pushed by the levers to wrap the same row of the cymbals on the rotating cage. The rice seedlings in the bowl are topped out in turn, and the seedlings fall into the field along the guiding seedling tube to complete the orderly transplanting operation. A rotating "star"-shaped replica wheel 25 is mounted at the position between the lower rear side of the cage and the guide tube, and the "finger"-shaped tooth rotates into the empty bowl of the tray that rotates with the cage. , the bowl of the bowl deformed by the action of the ejector pin 21 is restored to its original state. Below the outside of the cage, the front and lower positions of the replica wheel 25 are provided with a stopper 26 fixed to the frame. When the empty tray falling from the cage hits the stopper 26, it slides down the stopper 26. At the same time, due to the support blocking action of the stopper 26, the buckles on the trays which are originally overlapped and joined together are separated, and the lower trays are dropped into the recovery trays on the frame. The rotation speed of the cam and the rotating cage is different. In this embodiment, the rotation speed ratio is 52. When the rotating cage rotates through the same circle phase, the winding angle between the two bowls is adjacent, and the central axis just rotates once. This kind of seedling transplanting machine, because of the differential transmission of the disc and the cam, and the amplification of the lever mechanism, greatly improves the speed of the topping out of the seedling, and the phase difference between the eight cams is theoretically calculated and The high-speed camera experiment analysis confirmed that the uniformity of the ejection of the same row of seedlings and the uniformity of the plant spacing were ensured. The tray-reversing device makes the tray reusable and reduces the input cost of farmers.
