That is, the seedling mounting surface of the seedling mounting stand 8 of the planting section 11 is the second seedling mounting surface.
As shown in the figure, the seedling loading section 8A has multiple rows corresponding to the number of seedling planting rows by the illustrated riding rice transplanter, and is divided in the width direction by partition protrusions 14. are each provided with a seedling stopper 15.

As shown in FIG. 2-5, each seedling stopper 15 is
A plurality of (three) curved stopper frame rods 1 that are gate-shaped in plan view are attached to the frame plate 16 that is aligned along the width direction of the seedling loading section 8A.
7 are fixed at both leg ends of each frame rod 17.

A pair of brackets 18 are fixed to the frame plate 16 at both ends thereof, and a pair of brackets 18 are provided at the lower end of the seedling stand 8 along the width direction of the stand 8 in a through hole 18a formed in the bracket 18. The stopper frame rod 17 is attached to the frame board 16 by inserting one of the multiple rod-shaped seedling leaf retaining bodies 19 for preventing the seedling leaves from drooping. Around the leaf locking body 19, the stopper frame rod 17 protrudes toward the surface of the seedling table 8, as shown by the solid line in FIG. As shown in phantom lines in FIG. 3, the stopper frame rod 17 is pivoted to a standby position where the stopper frame rod 17 is lifted up from the surface of the seedling table 8 and the lower portion of the frame rod 17 is wide open.

Further, another bracket l-20 is fixed at one end of the frame plate 16 at an appropriate angle to the bracket 18, and the following operating rod 21 is attached to this other bracket 20. I've let it happen.

That is, as shown in FIG.
A stopper head 22 and a pin hole 23 are formed in the tip bent into a letter shape, and the tip is inserted into the through hole 20a of the bracket 20. By supporting the bracket 20 with a pin (not shown) to prevent it from coming out, the tip of the bracket 20 can be attached to the frame plate 1.
It is rotatably connected to 6.

As shown in FIGS. 2 and 3, this operating rod 21 is guided along the vertical direction of the seedling platform 8 to the upper end position of the seedling platform 8. As shown in FIG. 2, the two operating rods 21 for the seedling loading section 8A are provided in parallel with each other at a position above the partition ridge 14 between the two seedling loading sections 8A.

Further, as shown in FIG. 3, the base end of each operating rod 21 is curved semicircularly in a direction protruding from the surface of the seedling table 8 to form a handle portion 24.

The leg portion 25 at the end of the handle portion 24 is connected to the partition protrusion 14.
The base end of the seedling stand 8 is inserted into a long hole 26-\ as shown in FIG.

Both brackets on the frame board 16 of the seedling stopper 15} 18. 20, by moving the operating rod 21 forward and backward,
When the operating rod 21 is in the retracted position, the stopper frame rod 17 is positioned at the operating position shown in solid lines in FIGS. The stopper frame rod 17 is provided in such a way that the base end of the elongated hole 26 is formed with a horizontally bent portion 26a.
In the retracted position of the operating rod 21, in which the lever 7 is placed in the operating position, the handle portion 24 is slightly moved laterally at the base end of the elongated hole 26, and the leg portion 25 is brought into contact with the inner end surface of the bent portion 26a. The retracted position of the operating rod 21 is regulated.

Further, the forward position of the operating rod 21, which places the stopper frame rod 17 in the standby position, is such that the leg portion 25 at the base end of the rod 21 comes into contact with the inner end surface of the elongated hole 26 as shown by the imaginary line in FIG. In this state, the fifth
As shown by imaginary lines in the figure, the through hole 20 to which the tip of the operating rod 21 is pivoted passes over the position of the through hole 18, which constitutes the rotational fulcrum of the stopper frame rod 17, in the vertical direction of the seedling stand 8. This is designed to prevent unexpected rotation of the stopper frame rod 17 in the direction of the operating position.

In addition, in the vicinity of the lower end of the seedling stand 8, upper and lower support rods 27 and 28 are attached along the width direction of the seedling stand 8, as shown by the two-dot chain line in FIG. A pair of seedling mat holding rods 29 are provided in the loading section 8A.

The seedling stopper device shown in FIGS. 1-7 according to this invention is constructed as described above, so that when planting seedlings at the edge of a ridge, seedlings can be planted on one or more specific rows. If not, the operator extends his hand from above the passenger seat 5 in the direction of the seedling platform 8, and presses the operating rod 21 for the seedling loading section 8A of the specific row.
By holding the handle portion 24 at the base end and pulling it backward, the seedling stopper 15 or its stopper frame rod 17 is brought from the standby position shown by the imaginary line in FIG. The stopper frame rod 17 that comes into contact with the 8 sides of the seedling table prevents the seedling mat in the same section 8A from descending, so that the seedlings can be stopped as required.

To release the seedling stop, the operator similarly holds the handle 24 and pushes the operating rod 21 forward, moving the seedling stopper 15 or its stopper rod 17 from the operating position shown by the solid line in FIG. 2 to the operating position shown by the imaginary line. By bringing it to the standby position, the lower part of the frame rod 17 that has been sprung up can be opened.

During such operations, the elongated hole 26 not only regulates the position of the operating rod 21 using the inner end surface of its proximal bent portion 26a and the inner end surface of the elongated hole 26 itself, as described above. , performs a guide function of guiding the operating rod 21 with its proximal leg portion 25.

In particular, since the two operating rods 21 for the two adjacent seedling loading sections 8A are provided in parallel in both sections 8A as described above, the supply of seedlings from the two adjacent seedling loading sections 8A is stopped. and when such suspension of supply is lifted,
The two parallel operating rods 21 can be moved forward and backward at once with one hand, making it possible to operate the seedling stopper 15 extremely quickly in such a case.

Next, another embodiment shown in FIGS. 8-10 will be explained. In this other embodiment, as shown in FIGS. 8 and 9, the upper support rod 27 for the seedling mat holding rod 29 is A gate-shaped seedling stopper 30 for one seedling, which is rotatably supported at the ends of both side legs 30a, is provided at the lower end position of each seedling loading section 8A.

Then, an operating rod 32 extending along the vertical direction of the seedling platform 8 is attached to the curved lever 31 attached to each seedling stopper 30.
The two ends of the operating rod 32 are pivotally connected and guided to the upper end of the seedling stand 8.

As in the case of the previous embodiment, the two operation rods 32 for the two adjacent seedling compartments 8A are connected to the partition protrusion 14 between the two compartments 8A.
They are arranged in parallel above each other.

In another embodiment, as shown in FIG. 10, an elongated hole 33 is formed in the seedling stand 8 in the shape of a notch from the upper end at the position of the partition protrusion 14, as shown by the solid line in FIG. When the operating rod 32 is pulled back and the seedling stopper 30 is brought to the operating position where its distal horizontal rod portion contacts the surface of the seedling platform 8, the seedling stopper 30 is brought into contact with the upper end surface of the seedling platform 8 on the side of the base of the elongated hole 33. As shown by the solid line in FIG.
By making contact with the seedling stopper 30, the operating rod 32 is pushed forward as shown by the imaginary line in FIG. When the bending operation section 3 is brought to the standby position, the bending operation section 3
2a are brought into contact with the inner ends of the elongated holes 33, so that the forward and backward positions of the operating rods 32 are regulated.

As shown in FIG. 9, when the seedling stopper 30 is in the standby position, the tip of the operating rod 32 is designed to exceed the position of the support rod 27, which is the rotational fulcrum of the seedling stopper 30, toward the lower end of the seedling platform 8. is the same as in the previous embodiment, and this prevents the seedling stopper 30 in the standby position from unexpectedly rotating toward the operating position.

In the other embodiments of the seedling stopper device, the seedling stopper 30 is rotated between the operating position shown by the solid line in FIG. 9 and the standby position shown by the phantom line in FIG. It can be used in the same way as the example, and when stopping the supply of seedlings from the two adjacent rows of seedling compartments 8A, and when canceling such a stop on the supply of seedlings, the operation for that purpose is performed using the two rows. This can be done by simultaneously operating the operating rods 32.

Note that, as described above, the elongated hole 26 or 33 that guides the operating rod 21 or 32 at the proximal bent portion of the rod and restricts the forward and backward positions of the operating rod with the inner end surface and the proximal side end surface is this. may be changed to a long groove 40 as illustrated in FIG. 11a.

The long groove 40 shown in FIG. 11a is shaped like a notch from the upper end of the seedling stand 8, similar to the long hole 33, and FIG. It is drawn in relation to the long groove 40 described above.

Note that instead of the elongated hole 26 or 33 or the elongated groove 40, two circular locking holes 50, as illustrated in FIG. 11b,
51 is provided at the upper end of the seedling stand 8, and each of the locking holes 50,
By selectively inserting and locking the base end of the operating rod in 51, it is also possible to restrict the forward and backward positions of the forward and backward movement lever.

FIG. 11b shows that the base end of the operating rod 21 is connected to the locking hole 50.
, 51.

As described above, the seedling stopper device in the rice transplanter of this invention is provided at the lower end position of each seedling loading section 8A of the seedling loading platform 8 in the rice transplanting machine equipped with the seedling loading platform 8 that is inclined upward in the direction of the operating position. A seedling stopper 15 or 30 is rotatably supported between an operating position and a standby position, and a seedling stand 8 is provided.
The operating rod 21 or 32 is movable forward or backward along the inclination direction, and its tip is connected to the seedling stopper 15 or 30 of each seedling loading section 8A by moving the operating rod forward or backward. The operating rods 21 or 32, which are interlocked and connected so that they cannot be rotated or rotated, are arranged so that the two operating rods for two adjacent rows of seedling loading sections are parallel to each other between the two seedling loading sections. The operating rod, which has its base end guided to the upper end of the seedling table, can be operated very easily by the operator. Since the seedling stopper can be moved forward and backward, it is not only easy to move the seedling stopper between the working position and the standby position, but it is also possible to move the two operation rods for two adjacent rows of seedling loading sections in parallel. In addition, since the two seedling stoppers in both seedling loading compartments can be operated at the same time, when stopping and canceling the supply of seedlings in two adjacent seedling loading compartments, such operations can be performed all at once. The operation time is shortened, and as a result, the seedling stopper device can be operated as easily as possible and improve work efficiency.

According to one embodiment of this invention, the bent portion 25 or 32a'M of the base end of each operating rod is inserted into the elongated hole 26 or 33 or the elongated groove 40, which is shaped along the direction of movement of the operating rod; When configuring the seedling stopper device according to the present invention so that the bent portion is brought into contact with the inner end surface and the proximal side end surface of the elongated hole or elongated groove to regulate the forward and backward positions of each operating rod, Compared to the case where such an operating rod is attached to and removed from a support part in order to regulate its position, redundant operations are omitted and the simple structure makes it easier to operate. In addition, the long hole or groove described above also serves as an operating guide for the operating rod, allowing smooth operation of the seedling stopper.
