Description

[Detailed Description of the Invention] The present invention relates to a seedling feeding device in a seedling platform of a rice transplanter that can intermittently feed out grouped seedlings placed on the seedling platform toward the seedling take-out side.

Conventionally, this seedling dispensing device has been provided with a bottom dispensing rotary body that rotates intermittently on the bottom of the seedling platform, or a side dispensing rotary body that rotates intermittently on a vertical axis on the upright wall of the seedling platform. Therefore, in the former case, the sideward feeding of the grouped seedlings is delayed due to the contact resistance between the standing wall of the seedling stand and the grouped seedlings, and in the latter case, on the contrary, the bottom side of the grouped seedlings is delayed. In any case, there was a drawback that the feeding of the seedlings could not be carried out uniformly. Therefore, it has been proposed to have both a bottom feeding rotor and a side feeding rotary body, but the structure is complicated and it is difficult to match the feeding timing of both rotating bodies, so it is still not ideal. However, it was not possible to uniformly feed out a group of seedlings.

In view of the above-mentioned actual situation, the present invention eliminates these drawbacks and is equipped with both a bottom feed-out rotary body and a side feed-out rotary body, yet has a simple structure, and has a structure that allows both rotary bodies to be fed out. It is an object of the present invention to provide a seedling feeding device in a seedling mounting stand of a rice transplanter, which is capable of uniformly feeding out grouped seedlings in an ideal manner by perfectly matching the timing.

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. 1 is a traveling body of a walking type rice transplanter implementing the present invention, and the front part of the body frame 1a of the traveling body 1 is is equipped with an engine 2, and a seedling stand 3 that is low in the front and high in the rear is installed at the rear so as to be able to reciprocate intermittently in the left and right directions. 4 is the aircraft propulsion wheel, 5
：Tamen sliding float, 6：driving handle, 7
is a planted nail.

A plurality of rising walls 8 are protruded from the seedling stand 3 in the front and back direction, and a group of seedlings A is provided between each rising wall 8.
The pine-shaped clustered seedlings A can each be placed on the seedling placement surface 3a. Notches 9, 9a are bored in the seedling mounting surface 3a of the seedling mounting table 3 at the lower end of the slope and in the side surface 8a of the rising wall 8 at substantially the same positions in the left and right direction. Reference numeral 10 denotes a rotating shaft supported in the left-right direction below the notch holes 9, 9a, and the rotating shaft 10 is interlocked and connected to an intermittent rotational drive mechanism (not shown) to interlock with the intermittent reciprocating movement of the seedling stand 3. It rotates intermittently by a predetermined amount. The rotating shaft 10 has a bottom feeding rotary body 11 corresponding to the notch holes 9 and 9a.
Although the side feeding rotary body 12 is fixed, the bottom feeding rotary body 11 corresponding to the notch hole 9 has an intermediate portion 11a slightly lower than the seedling mounting surface 3a in this embodiment.
The left and right end portions 11b are slightly higher and protrude above the seedling mounting surface 3a by a height l. On the other hand, the side feeding rotary body 12 corresponding to the notch hole 9a of the upright wall side surface 8a
One end on the side of the seedling surface is shaped like a truncated cone, with the radius becoming smaller toward the end.
The seedling loading side feeding surface 12a protrudes toward the seedling loading surface side, that is, inside the seedling loading table 3, by a protruding width L that is approximately equal to the protruding height l of the bottom feeding rotary body 11 with respect to the side surface 8a of the rising wall, and furthermore, The radius of the protruding feeding surface 12a is slightly larger than the radius of both left and right ends 11b of the bottom feeding rotor 11, and therefore the peripheral edge of the feeding surface 12a is equal to the protruding height of both left and right ends 11b with respect to the seedling loading surface 3a. l
It is now located at a height L' that is slightly higher than the previous one.

Next, in order to carry out seedling planting work using the rice transplanter implementing the present invention configured as described above, first, the group of seedlings A is placed on the seedling platform 3, and then the planting claws 7 are moved in a reciprocating circular motion. The method of dividing the group of seedlings A on the seedling stand 3, which moves intermittently in the left and right directions, into seedlings destined for planting and planting them on the rice field is the same as in the conventional method.

In such seedling planting work, the group of seedlings A on the seedling platform 3 is fed out by a predetermined amount in the seedling scraping direction by a feeding rotor that rotates intermittently in synchronization with the movement of the seedling platform 3. However, at this time, group seedling A is
The bottom surface and both left and right sides that are in surface contact with the seedling platform 3 are simultaneously fed out by a bottom feeding rotary body 11 and a side feeding rotary body 12, which are fixed to the same rotating shaft 10. The body 12 is the seedling side feeding surface 1
2a protrudes inward from the rising wall side surface 8a by a width L and feeds out both sides of the group seedlings A in a pinch-like manner.
The grouped seedlings A can be evenly fed out without causing any delay, lifting, or buckling due to friction with the seedling platform 3. Moreover, the side feeding rotary body 12 has a protruding seedling loading surface 12a that is slightly higher than the height l of the left and right ends 11b of the bottom feeding rotating body 11 from the seedling loading surface 3a by L'. Because of the protrusion, the amount of feeding of the bottom surface of the grouped seedlings A by the bottom feeding rotor 11 and the amount of feeding of the side surface of the grouped seedlings A by the side feeding rotor 12 are approximately the same, so that the grouped seedlings A can be fed more evenly. I can put it out.

In the above embodiment, the rising wall 8 located in the middle of the seedling stand 3 was provided with side feeding rotors 12 on both sides 8a of the rising wall, but as shown in FIG. In addition, the protrusion width L from the upright wall side surface 8a and the protrusion height L' from the seedling loading surface 3a on the seedling loading side feeding surface 12a of the side feeding rotating body 12 are as follows. Although optional, the important point is group seedling A
It is sufficient that the side surface protrudes to the extent that it does not come into contact with the rising wall side surface 8a and cause a delay in feeding.

In summary, the present invention provides a seedling stand for a rice transplanter in which the grouped seedlings placed on the seedling stand are intermittently fed out to the seedling take-out side. In addition to providing a bottom feed-out rotary body that comes into contact with the bottom surface, a side feed-out rotary body that rotates simultaneously with the bottom feed-out rotary body is provided on the upright wall of the seedling stand, and a seedling loading side feed-out surface of the side feed-out rotary body is provided. Since it is provided so as to protrude in the direction of the seedling loading surface from the side surface of the upright wall and come into contact with the side surface of the grouped seedlings, the structure is simple, and the bottom side of the grouped seedlings is fed out by the bottom feeding rotor. teeth,
By means of the side feed-out rotating body that protrudes from the side surface of the rising wall and rotates simultaneously with the bottom feed-out rotating body, the side surfaces of the grouped seedlings can come into contact with the side surface of the rising wall and be fed out almost simultaneously with the bottom surface without any delay. This makes it possible to uniformly feed out seedlings over the entire surface of the group of seedlings.
