点があつた。 In general, a seedling feeding rotary body that intermittently feeds out pine-shaped clustered seedlings is mounted on the lower end of the slope of a seedling stand mounted on a traveling machine, and the pine-shaped clustered seedlings are fed out through seedling planting claws. However, the conventional seedling feeding rotary unit separates the seedlings into seedlings with raised parts installed on the seedling platform. Since it was positioned within the left and right width of the surface, when the pine-like clustered seedlings are fed out, the left and right end surfaces of the pine-shaped clustered seedlings come into contact with the rising part, generating resistance such as frictional resistance and sliding resistance. As a result, the amount of feeding is different between the central part and both left and right sides of the pine-like clustered seedling, which has the disadvantage that uniform feeding cannot be performed over the entire width of the left and right sides.

欠点があつた。 Moreover, the above-mentioned resistance of the left and right end surfaces of the pine-shaped clustered seedlings differs depending on the width of the pine-shaped clustered seedlings, the state of rooting, etc., which causes unevenness in the amount of seedlings released, and the seedlings are divided into an appropriate number of planted seedlings. There was a drawback that I couldn't do it.

置を提供せんとするものである。 The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation, and its purpose is to provide a seedling feeding rotor that feeds out both left and right sides of pine-like group seedlings. It is formed so that its position can be freely adjusted in the left and right directions, and it is configured so that it can be inserted into the inside of the rising part, so that the pine-like group seedlings can be uniformly spread over the entire width in the left-right direction, regardless of the width or rooting condition of the pine-like group seedlings. To provide a seedling feeding device for a rice transplanter, which can be fed out, and which can always divide an appropriate number of planted seedlings from a pine-like group of seedlings and plant them on the rice field.

る。 The structure of the present invention will be explained with reference to an embodiment shown in the drawings. 1 is a running body of a rice transplanter, and the running body 1 includes an engine 2, a float 3,
The aircraft is equipped with propulsion wheels 4 and a drive case 5. Numeral 6 is a seedling stand provided above the drive case 5, and a driving operation handle 7 is provided on the rear side of the seedling stand 6. Reference numeral 8 denotes a helical shaft built into the drive case 5, and the helical shaft 8 is operatively connected to the engine 2 via a transmission chain 9, a transmission shaft 9a, a transmission chain 9b, and the like. As the helical shaft 8 rotates, the slide bar 10, whose both ends are connected to the right and left ends of the seedling stand 6 via brackets 10a, is guided by the helical groove carved in the helical shaft 8. , so that it can reciprocate from side to side together with the seedling table 6. Reference numeral 11 denotes a seedling dispensing mechanism, and a rotary shaft 12 of the seedling dispensing mechanism 11 is provided with a ratchet gear 13 and a rotation operating arm 14. Immediately after the seedling planting claw 15 performs the final division operation, the rotation arm 14 is rotated against the booster 17 by the rotation cam 16 provided on the transmission shaft 9a, thereby intermittently It is supposed to rotate.

プロンである。 Reference numeral 18 denotes a rising portion provided on the seedling platform 6, and a seedling mounting surface 6a for pine-shaped clustered seedlings is formed on the seedling platform 6 sandwiched between the rising portions 18.
Seedling feeding rotors 19 and 19a are provided on the rotary shaft 12 located at the lower end of the slope of the seedling platform 6, and as the rotary shaft 12 rotates, the seedling surface 6
The seedling dispensing rotary body 1 is arranged so that the pine-shaped clustered seedlings placed on the surface a are brought into contact with the bottom surface of the bed soil and disbursed by a predetermined amount.
9 and 19a are designed to protrude from a working hole 6b formed in the seedling stand 6. Among these seedling dispensing rotors, the seedling dispensing rotors 19a at both left and right ends of the seedling loading surface 6a are slidably inserted into the rotary shaft 10, and are fitted with pins 20 and pin holes 20a provided in the rotary shaft 12.
Accordingly, the side surface of the seedling delivery rotary body 19a can be freely adjusted to move in the left-right direction from a position substantially the same as the rising surface 18a to a position reaching inside the rising portion 18. 21 is a key body interposed between the seedling feeding rotary body 19a and the rotating shaft 12. Further, 22 is an apron.

とは、従来どおりである。 Next, the operation of the present invention constructed as described above will be explained. When planting seedlings,
As the traveling machine 1 travels, the pine-shaped group of seedlings placed on the seedling mounting surface 6a is divided into seedlings for unit planting by the seedling planting claws 15, and the seedlings are planted on the rice field. That's right.

ツト状集団苗の繰出しをすることができる。 In this case, when the seedling platform 6, which reciprocates from side to side, moves to the end of left and right movement and the seedling planting claw 15 performs the final dividing operation, the rotating shaft 12 rotates by a predetermined amount together with the seedling feeding rotors 19, 19a, The grouped seedlings will be sent out towards the bottom of the slope. At this time,
Depending on the rooting condition and width length of the pine-like group seedlings, the left and right edges and the rising surface 1 of the rising part 18
The resistance will be different from 8a, but if this resistance is large, the left and right sides of the pine-like collective seedling will be delayed, whereas if the resistance is small, the central part will be delayed. Therefore, by removing the pins 20 from the pin holes 20a and adjusting the seedling feeding rotary bodies 19a located at both left and right measuring ends of the seedling loading surface 6a in the left-right direction, the amount of contact with the bottom surface of the bed soil can be adjusted. , the amount of pine-shaped clustered seedlings that are fed out can be made uniform across the left and right sides. That is, when the resistance with the upright surface 8a is large, the seedling feeding rotary body 19a is positioned on the side of the seedling loading surface 6a so that the contact surface with the bottom surface of the bed soil is large; If it is located on the side of the rising part 18 so that the contact surface with the bottom is small, the seedling pulling force by the seedling feeding rotary body 19a can be adjusted, and therefore, regardless of the state of the pine-like clustered seedlings. , it is possible to always unroll the pine-like clustered seedlings evenly from side to side.

の分割を確実に行うことができるものである。 In short, the present invention provides a rice transplanter in which a seedling feeding rotary body that rotates intermittently is provided on the lower end side of a slope of a seedling loading table mounted on a traveling machine body. The seedling dispensing rotor on the side of the rising section is formed so that its position can be freely adjusted in the left and right direction and can be inserted into the inside of the rising section. Even if the rooting condition and width are different, the width of contact with the bottom of the bed soil can be adjusted freely by adjusting the position in the left and right directions according to these.
Therefore, the pine-like clustered seedlings can always be fed evenly and uniformly over the entire width, regardless of the amount of resistance with the rising part, and the appropriate number of seedlings to be planted can be reliably divided. It is something that can be done.
