Description

[Detailed description of the invention] Conventionally, when planting on headlands, banks, etc., a seedling stopper attached to a seedling stand was used to prevent some pine seedlings from being sent out. Since the device was designed to receive the end face of the bed soil on the delivery side, the pine seedlings had to be pulled up each time, resulting in extremely poor work efficiency.

This invention allows the bed soil to be received with one touch without having to pull up the pine seedlings, and the seedling stopping arm of the seedling stopping device acts on the bed soil in the opposite direction to the direction in which the seedlings are sent out, thereby reliably preventing the sending out of the seedlings. The present invention aims to provide a seedling fixing device for a rice transplanter that can be used in a rice transplanter, and in which a rice transplanter is provided with a sending body attached to the sending side of the bottom plate of each seedling resting part of a seedling resting stand, a horizontal shaft is provided above the seedling resting part. A plurality of seedling retaining arms are suspended from the horizontal axis with respect to one seedling resting part, and the lower part of the seedling retaining arm is directed against the upper surface of the seedling near the transmitting body in the direction opposite to the sending direction. The seedling retaining arm is bent to pierce at an acute angle from the base, and the seedling retaining arm is rotated downward by an operating rod to pierce the upper surface of the seedbed to catch bed soil and press it against the bottom plate of the seedling stand; The device is characterized in that it is configured to take a retracted position in which it is rotated upward.

The embodiment shown in the drawings will be explained below.1
is a planting device for a riding rice transplanter that is connected to the rear of a traveling vehicle by a link holder 2, a top link 3, and lower links 4, 4 so as to be movable up and down, and includes a plurality of planting transmission cases spaced apart laterally. 5a is attached to the shaft case 5, a plurality of floats 7 are attached below it that are raised and lowered by levers 6, and a drive case 8 that receives input from the PTO shaft of the aircraft is attached to the center of the shaft case 5. A seedling platform 10 that reciprocates laterally is supported by a screw shaft 9 on the rear surface, and the planting transmission case 5
A planting rod is attached to the rear of the seedling stand 1.
0 is a plurality of partition walls 10b between both side walls 10a and 10a.
..., each side wall 10a and partition wall 10b
Supports 11... which are U-shaped in side view and have a U-shaped bearing portion at the upper end of the front part are erected, and these supports 11... have horizontal shafts 12 corresponding to the respective seedling mounting portions 10c... ...is rotatably supported.

The upper ends of a plurality of seedling retaining arms 13 whose lower portions are bent rearward in the seedling delivery direction are fixed to the horizontal shaft 12, and the bases are attached to arms 14 protruding from the end of the horizontal shaft 12. The operating rod 15 which is pivotally connected to the side wall 10a
Alternatively, it extends diagonally forward and upward along the partition wall 10b and is inserted into the receiver 16.

Moreover, between the arm 14 and the base of the support column 11, when the operating rod 15 is pulled as shown by the solid line in FIG. A toggle spring 14a is tensioned so that when the operating rod 15 is pushed, the toggle spring 14a moves to the lower side.

Reference numeral 16 denotes an apron that receives the end surface of the bed soil 17 for pine seedlings.By moving this apron back and forth, the amount of bed soil 17 scraped by the planting rod can be adjusted. The feeding wheel 18 serves as a feeding body that is supported on a shaft and partially protrudes above the bottom plate.
The pine seedlings are sent out by rotating intermittently at the end of the horizontal movement.

Further, at the upper part of the upright portion 11a on the lower side of the support column 11, a seedling holding rod 19 for pressing the upper surface of the soil bed is supported by a support shaft 20.

In the above-mentioned device, the planting rod moves up and down while drawing a rotation locus a and extends from the notch of the apron 16 by 1.
Scrape off the soil from the base of the plants and plant them on the rice field.

When planting on the headland or along the shore, the operator extends his hand from the driver's seat on the vehicle and presses the appropriate number of operating rods 15 on the side.
3 rotates in the opposite direction to the delivery direction and pierces the bed soil 17 as shown by the chain line in FIG. At this time, since the receiving direction of the seedling retaining arm 13 is opposite to the feeding direction, even if the feeding wheel 18 operates, the bed soil is reliably received, and the bent part of the lower part connects the seedling bed to the bottom plate of the seedling tray 10c. Hold it in the pressed position.

Note that the seedling retaining arm 13 may be provided on the upper side than the feeding wheel 18, as shown by the symbol A in FIG.
Moreover, it can be applied to a traveling rice transplanter by extending the grip part of the operating rod 15 to the control part.

The present invention provides a rice transplanter in which a sending body is attached to the sending side of the bottom plate of each seedling resting part of a seedling stand as described above, in which a horizontal shaft is supported above the seedling resting part, and the horizontal shaft is aligned with the rice transplanter. A plurality of seedling retaining arms are hung vertically from one seedling resting part, and the lower part of the seedling retaining arm is bent so as to pierce the upper surface of the seedbed near the sending body at an acute angle from the direction opposite to the sending direction. The seedling retaining arm is rotated downward and rotated using the operating rod to pierce the upper surface of the seedbed to catch the seedbed and press it against the bottom plate of the seedling stand, and the arm is rotated upward to take a retreating position. Therefore, when the sending out of pine seedlings on the seedling stand is partially stopped, when the seedling stop arm is rotated in the opposite direction to the sending out direction of the seedlings using the operating rod,
The bent part at the bottom pierces the surface layer of the seedbed with good rooting at an acute angle, and the bent part presses the seedbed against the bottom plate, reliably preventing the matsutoto seedlings from falling off even if the machine body vibrates. I can do it.
