Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seedling holding device for a rice transplanter that can hold seedlings on the lower side of a seedling mat placed on a seedling placing table in the vicinity of a seedling take-out plate from above.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 6, in a rice transplanter configured by arranging a plurality of lower seedling mat retainers made of fine rods in parallel above the lower portion of the seedling placing table 2 in the vicinity of the seedling taking-out plate 1, In each lower seedling mat retainer a which is hung vertically from the support plate 6, the front end portion 5a of the lower portion 5 on the seedling mat B side is bent upward, but the rear end portion 5b is straight rearward. It was shaped so that it would extend out and project.

[0003]

[Problems to be solved by the device]

 Therefore, the lower end of the seedling mat B is pressed too much by the rear end portion 5b protruding straight, and the remaining seedlings remaining on the lower side of the seedling mounting table 2 are pulled out to the upper side of the seedling mounting table 2. When removing the seedlings, the rear end portion 5b extending straight is left behind and stuck to the seedlings so that it is difficult to remove, and the seedling residue is damaged or the lower seedling mat retainer a itself is deformed. When carrying out, there was a problem that the seedlings were pressed down.

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such a problem and to implement it suitably, and therefore, the front and rear end portions of the lower part of the seedling mat side of each lower seedling mat holder are bent upward to form a curved shape. Each of the lower seedling mat retainers is formed so as to be pivotable to the upper side of the seedling mounting table about the upper fulcrum axis and elastically urged downward to be pivotally mounted on the fulcrum axis. ..

[0005]

[Operation] Therefore, since the rear end side portion of the lower part of the lower seedling mat retainer is also bent upward and biased downwardly, the lower part of the lower seedling mat can be pressed upward and the seedling retainer can be pressed down properly. In addition, when pulling out the remaining seedlings left under each lower seedling mat retainer upwards and taking them out, while the entire lower seedling mat retainer rotates upward, the bent rear end part becomes the seedling mat. By just putting it in that state, you can take it out smoothly.

【Example】

 1 to 4, a vertical feed belt 7 is provided at the bottom above the seedling taking-out plate 1 having a seedling taking-out port through which a planting claw that moves along a trajectory A passes, and reciprocates in the lateral direction. A movable seedling placing table 2 is installed obliquely, and the seedling mat B is placed on the seedling placing table 2 in the same manner as the conventional structure. Support frames 8 are erected on the ribs 2a of each of the support frames 8. Both ends of a fulcrum shaft 4 having a cross-section cutout 4b formed on the inner surface are fitted to the upper portions of both support frames 8 respectively. , And the engaging projection having an L-shaped cross section which can abut against the notch 4b on the inner peripheral surface of the mounting hole 10 of the wide mounting base 9 which is fitted and vertically installed on the fulcrum shaft 4. 10a is formed and is a fulcrum projecting from the support frame 8. One end side of the torque spring 11 which is fitted into the tip end portion 4a of the shaft 4 is engaged with the pin 12 above the end portion of the mount 9. In addition, the other end side is engaged with the pin 13 on the outer side of the support frame 8, and the upper end portions of the lower seedling mat retainers A juxtaposed side by side at predetermined intervals in the lateral direction are attached to the lower portion of the mount 9. Each side of the lower seedling mat holder A is fixed to the side surface via a bolt 14a and a nut 14b, but each lower seedling mat retainer A has one thin rod that contacts the seedling mat B. Is bent upward so as to have a curved shape and is bent so as to have a triangular loop shape as shown in FIG.

FIG. 5 shows another embodiment, in which the lower seedling mat retainer A is formed in substantially the same manner as indicated by the same reference numeral as the above embodiment, but the upper portion of the rear end side portion 3b is bent further inward. It was formed.

Therefore, as shown in FIG. 1, the lower seedling mat retainer A is moved downward by the torque spring 11 until one side of the engaging projection 10a abuts against one side of the notch 4b, as shown by an arrow B. Since the rear end side portion 3b of the lower part 3 of the lower seedling mat retainer A is bent upward due to the urging force, the lower part of the seedling mat B can be properly restrained from above. When the remaining seedlings left under each lower seedling mat retainer A are pulled out upward as shown in FIG. 4 as indicated by the arrow C, the other side of the engaging protrusion 10a is notched. The entire lower seedling mat retainer A can be pulled against the torque spring 11 and pivoted upward as indicated by arrow D until it abuts against the other surface of the portion 4b. Smoothly remove the side part 3b along the seedling mat B Can be issued.

[0009]

[Effect of the device]

 In this way, according to the present invention, since the rear end side portion 3b of the lower part 3 of the lower seedling mat retainer A is also bent upward and biased downward, the lower part of the seedling mat is properly pressed from above. The seedlings can be pressed, and when the remaining seedlings left under each lower seedling mat retainer A are pulled out and taken out, the entire lower seedling mat retainer is rotated upward around the fulcrum axis 4. By simply sliding the bent rear end side part 3b along the seedling mat, it can be taken out smoothly without being caught or deformed by the seedling mat as in the conventional case, and a simple structure is suitable. It has features that can be implemented.
