[Prior art 1] Conventionally, there is a planting i*a in which seedlings placed on a seedling stand are taken out from a seedling take-out port and planted on the rice field. A gear case extending radially for a predetermined length from the center of rotation is pivotally supported so as to rotate in one direction.
A seedling retrieval/planting mechanism (planting body) is attached to the tip of this gear case, and a gear train is provided inside the gear case.
A planting device is known in which the attitude of the seedling take-out/planting mechanism is shifted between a seedling take-out attitude and a seedling planting attitude as the J car case rotates. [Problem to be solved by the invention 1] In the above-mentioned planting device, the planet W meshing with the sun gear via the intermediate gear: JIt! The tip of the planting body (seedling retrieval/planting mechanism) fixed to the shaft moves in an elliptical trajectory, but due to backlash between each FG model or manufacturing error in the distance between the gear axes, the planting The attached body has some play in the circumferential direction around the play gear shaft, and as a result, the trajectory of the tip of the planting body may change due to the magnitude of the load when taking out the seedlings, or the influence of centrifugal force due to the high or low rotation speed. There is a risk of instability. The trajectory of the tip of the planting body is a major factor in determining the amount of seedlings taken out, that is, the number of plants per plant, and if this is unstable, the amount of biting of the tip of the planting body into the seedling mat will not be constant, and - There is a risk that the number of stocks will be uneven. (Means for Solving the Problems) Therefore, the present invention provides a system in which the tip of the seedling retrieval/planting mechanism (planting body) is fixed from just before taking out the seedlings from the seedling retrieval port to planting the taken out seedlings on the field surface. The device is characterized in that it is configured to eliminate play in the seedling retrieval/planting mechanism that causes backlash of the gear or error in the axial distance of the gear. [Function] Constructed in this way As a result, the interlocking trajectory of the seedling extraction/planting mechanism operates stably in a constant trajectory from the time of seedling extraction until the seedling is planted, allowing accurate seedling extraction and planting operations.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 shows a riding-type rice transplanter to which the present invention is applied. This riding-type rice transplanter is provided with an elevating link 2 at the rear of a passenger vehicle body 1 that moves up and down by the expansion and contraction of a hydraulic cylinder 3, and a rear part of this elevating link 2. The seedling planting device 4 is installed at. This seedling planting device 14 is mounted on a main body 5 which also serves as a transmission frame, so that it can reciprocate in the left and right direction with a predetermined stroke.
and a seedling mounting stand 6 supported in a forward-leaning manner, and this seedling mounting stand 6
A planting body transmission case 8 that rotates forward (in the direction of the arrow) about the rotation axis 7 is provided at a position facing the seedling take-out port (8 not shown) provided at the lower end of the slope of the planting body. A pair of planting bodies 9.9 are attached to both ends of the transmission case 8. Further, on the lower side of the main body 5, a pair of front and rear link bodies 10°1
0, a float 11 is mounted so as to be movable up and down. As shown in FIGS. 2 to 4, the planting body transmission case 8 is fixed to a rotating shaft 7 that projects horizontally through mission cases 12 to 7 langes 13 provided on the main body 5 and a boss portion 13a. A sun tooth l114 consisting of an eccentric gear provided coaxially with the rotating shaft 7 at the center in the longitudinal direction of the transmission case 8 has an end portion protruding from the transmission case 8 toward the 7 flange 13 side. is fixed to the boss portion 13a so as not to rotate. An intermediate tooth l115 and a planetary gear 1G, which mesh with the sun gear 14 and have the same gear V ratio and the same amount of eccentricity as the sun tooth l114, are supported in the transmission case 8 so as to mesh with each other. The rotating shaft 1 of the planet 1116 protrudes outside the transmission case 8.
7, the planting bodies 9, 9 are attached, and by rotating the planting body transmission case 8 by the rotating shaft 7, the planetary gear 16
revolves around the sun gear 14, and since it is an eccentric gear, it swings around a certain direction when viewed from the outside. The planting body 9 has one end of the main body 18 fixed to the rotating shaft 11,
A planting claw 19 is attached to the front edge of the main body 1B, and
The implantation fork 20 is movable within a predetermined range by passing through the main body 18 in the length direction, and is always urged toward the extrusion side by a compression spring 21 provided within the main body 18. A cam follower 22 is provided at the base end of the implantation fork 20 and slides into contact with a cam 23 (see FIG. 5) provided on the implant transmission case 8 side, and the implantation fork 20 is moved by the elastic force of the spring 21. We are working together with them to advance and retreat. Then, the tip of the implantation mold 19 moves in an elliptical trajectory shown by A in FIG. The fork 20 descends along the planting mold 19 to place seedlings on the rice field, and the planting fork 2o rises during the return stroke of the planting mold 19. When the planting device is configured with such a gear train, the free tooth 11
16 generally operates stably when operated at low speed and under no load, and the implantable type 19 operates in a stable trajectory. However, due to backlash of each gear or an unavoidable manufacturing error between the axes, there is a slight gap between fa of each gear, and there is also a large amount of resistance when taking out the seedlings, or due to the transmission of the implant. The operation of the planting claws 19 becomes unstable due to centrifugal force when the case 8 rotates at a high speed, and the number of seedlings I (number) taken out is not constant. For this reason, the cam 23 that moves the planting fork 20 up and down is shaped as shown in FIG.
In addition to the seedling seedling 11i, a planting claw 19 is provided before the seedling M enters the mat section, and the component force C (see Fig. 6) when the planting fork 20 slides on the cam 23 and descends B causes the planting. The pawl 19 is pushed up by 111 spaces between the gears, and the tip trajectory of the planting pawl 19 is stabilized until the period E when the planting fork 20 descends. In order to stabilize the trajectory of the tip of the planting claw 19, as shown in FIGS. 3 and 4, 3127! ! A roller 25 is attached to the side of the 611116 at the tip of an arm 24 that rotates together with the rotating shaft 17, and a thick 1% 1lleI! The base end is pivoted on the outer periphery of the boss portion 13a on the side of the spring 2, and the spring 2
A lever 27 is provided which is pressed by G and whose tip extends to the side of the planet 111B. As the roller 25 rotates, it comes into sliding contact with the lever 21 within a predetermined rotation range, and pushes up the lever 27 against the spring 2G. Further, when the lever 27 is not in sliding contact with the roller 25, it is in contact with a bearing 2B provided on the side of the intermediate gear 15 and remains stationary. In the fourth cause, when the O-ra 25 comes to the G position, it contacts the lever 27 and moves the lever 27 to the H position.
lift up. The portion of the tip of the lever 27 that makes sliding contact with the row 525 is curved with the same curvature as the rotation radius of the row 525, and the portion of the lever 21 that contacts the bearing 2B is also curved with the same curvature as the outer circumference of the bearing 28. There is. The lever 27 remains at rest from the 11th position to the summer position, and ■
Push the roller 25 in the opposite direction. In this pressing, the planetary gear 1G is reversely driven by the distance between the gears, and the planting pawl 19 attached to the planetary gear 16 is pushed up, and the planting pawl 1
9 It is designed to stabilize the tip trajectory. In addition, in the cam 23 shown in FIG. 5, B is a descending part to take up the gap between gears, D is a planting fork stopping part, E is a seedling part (planting fork 20 is lowered), and G is a planting fork rising. It shows the part. With this configuration, the implant transmission case 8 is rotated by the rotation shaft 7, the rotation shaft 17 is rotated by the intermediate tooth l115 meshing with the fixed sun gear 14, and the planetary gear 1G, and the implant is rotated. The planting claw 19 operates as shown in FIG.
At the U position, the seedling M is taken out, and at the same time, the planting fork 20 is operated at the P position to insert the seedling into the rice field. The cam 23 that slides into contact with the cam follower 22 when taking out the seedlings and inserting the seedlings (with a hammer) is shown in B and D in FIG. When the roller 25 is in the G-1 position relative to the lever 27, the planetary gear 16 is reversely driven by the distance between the gears, and the planting pawl 19 attached to the rotating shaft 17 of the planetary gear 16 is rotated.
Push up to stabilize the trajectory of the tip of the planting claw 19.

As explained above, according to the planting device of the rice transplanter according to the present invention, the tip of the seedling retrieval/planting mechanism (planting claw 19) operates for a certain period of time from just before taking out the seedlings from the seedling retrieval port to when the seedlings are inserted. Since the play caused by the backlash of the gear or the error in the axis distance of the gear is removed, the operation of the seedling retrieval/planting mechanism becomes stable, and the seedling retrieval mold (-the number of seedlings per stock) becomes constant. , it is possible to plant 1J in a predetermined posture. Further, even if the rotation speed of the gear case is increased to increase work efficiency, the operation of the implant remains stable, so there is no problem and the planting work can be made more efficient.
