Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for planting seedlings in a pot, in which adult seedlings grown in a seedling pot such as a paper pot are planted in a field, and in particular, a device for planting seedlings in a pot, in which seedlings are separated and planted. This is related to the improvement of.

In cold regions such as Hokkaido and the Tohoku region, if the seedlings for rice planting are small, they will be planted closer to maturity, which can have a negative impact on yield depending on weather conditions.

Therefore, the present applicant has previously proposed a pot seedling sheet that can be applied to a conventionally known rice transplanter for planting mat-shaped seedlings. As shown in FIGS. 8 to 11, this pot seedling sheet consists of a bot 1 made of paper and formed into an inverted truncated quadrangular pyramid shape, with its bottom surface open and a connecting portion 2 attached to the periphery of the bottom surface. A large number of them are successively connected in a base lattice shape to form a sheet of a predetermined size, and a seedling hole 4 is formed in the center of the top 3 of the bot 1. Then, with this potted seedling sheet housed in the seedling raising box 5, the seedlings are made to protrude from the seedling holes 4 to grow adult seedlings with soil to obtain a seedling sheet of the grown seedlings, and this sheet is used to form mat-like seedlings. The seedlings are supplied to the seedling stand of the rice transplanter for planting, and the seedlings are separated from each pot one by one using the body from one end of the seedling stand and planted in the field.

By the way, although the bot 1 is made of water-soluble paper, the conventionally well-known separating needle type or knife type of planting cannot be separated well with the body, and furthermore, the bot 1 has a reverse truncated shape. Because it has a square pyramid shape, it is not possible to securely hold the seedlings in the pot, causing them to fall or lose their posture while being moved to the stamp surface, making it impossible to plant them in the proper posture.

In view of the above-mentioned circumstances, the present invention improves the planting body so that the potted seedlings can be accurately separated from a continuous potted seedling sheet, held in a proper posture, and planted in the field in the proper posture. Pot seedling planting is an attempt to provide a device that can be used to plant seedlings in pots.

For this purpose, the present invention separates and holds the planting body using fingers that hold the bottom part of the potted seedling, a holding needle that pierces the root part of the potted seedling, and the separating claw and holding needle. The present invention will be described below with reference to embodiments shown in the drawings.

#! In FIG. 1, reference numeral 6 denotes a traveling vehicle body, which is adapted to travel by driving front wheels 1 and rear wheels 8. At the rear of the traveling vehicle body 6, a hydraulic cylinder 9 is used to move the vehicle up and down. Planting is carried out by the work machine 11 via the lifting link 10.
is installed.

For planting, the work machine 11 places the pot seedling sheet above the main body frame 12 which also serves as a transmission case, and uses a backward-tilting seedling platform 13 that reciprocates in the left and right direction at a predetermined stroke.
A seedling holder having a seedling outlet (not shown) is provided at the lower end of the slope of the seedling platform 13, and the plate 14 is connected to the main body frame 12.
At the same time, the seedling holder moves back and forth in a predetermined trajectory in the vertical direction facing the seedling take-out port of the board 14, and during the planting period, potted seedlings are taken out one by one from the seedling take-out port and planted on the rice field. Further, on the lower side of the main body frame 12, a float 16 is provided which supports the planting machine 11 on the field surface and is movable up and down.

As shown in detail in FIGS. 2 and 3, the implant 15 has a finger 18 and a retaining needle 1 on the front side of the main body 11.
9 are tightened with mounting screws 21 and 21 through washers 20, and this finger 18 and holding needle 19 are tightened.
A planting fork 22 is provided so as to be movable up and down, located behind the distal end side. The finger 18 has a mounting part 18a having an opening-shaped cross section, and extends downward from the mounting part 18a, and forms a window part 18b on the tip side, and is divided into two symmetrical parts. Both front corners (ridgeline portions) of the pot portion of the seedling are formed by finger portions 18c, 18c that abut and hold each other and have sharp tips. The holding needle 19 is bent into a U-shape and is attached to the washer 20 and the attachment screw 21 so as to be movable in the vertical direction. It extends downward along the front surface of the finger 18, is bent so as to enter the inside of the finger 18 through the window 18b of the finger, and further extends so that its tip protrudes slightly downward from the tip of the finger portion 18c, so that it can be used when taking out seedlings. It is formed with a needle part 19b that pierces the root part of the potted seedling.

Further, on the rear side of the main body 17, there are seedling guide claws 2 extending downward.
3 is attached by mounting screws 24.24.

On the other hand, an endless seedling feeding belt 25 is provided on the seedling mounting table 13 so that its upper surface is located on the seedling mounting surface as shown in FIG. It's starting to come out. In addition, as shown in FIG. 5, brackets 27ti! are provided on the left and right partition frames 26 (one is not shown) of the seedling stand 13. The supporting metal fittings 28 are passed to the rack,
Support frames 29, 29 are fixed to this support fitting 28. A frame 31 is attached to the support frame 29.29 so as to be vertically adjustable via adjustment screws 30.30. In the drawing, four (4) seedling guide rods 32 are attached, and as shown in FIG. The seedling sheet is pressed against the bottom side to prevent the seedling sheet from floating up.

Further, a seedling guide plate 33 is provided at the bottom of the plate 14 of the seedling tray.

In order to plant seedlings in pots with such a configuration, in the apparatus, a pot seedling sheet is placed on the seedling platform 13, and a spare pot seedling sheet is also placed on the preliminary seedling platform 34 provided on the traveling vehicle body 6. Then, rice planting work is carried out.

In the planting operation 1111, the float 16 slides in contact with a circular surface, and during the horizontal movement of the seedling platform 15, the seedling receiver separates and takes out the potted seedlings from the seedling take-out port of the board 14. Plant on the river surface.

At the time of taking out the seedling, the implant 15 is attached to the finger part 18c of the finger 18, as shown in FIGS. 2 and 4.
, 18c touch and hold the front ridgeline of the pot part of the potted seedling, and at the same time, the needle part 19b of the holder 1119 is inserted into the base of the potted seedling, and the finger 18 and the holding needle 1
9 securely hold the potted seedling, and in this state, place the transplanted body 1.
5 separates the potted seedling from the potted seedling sheet t, and in an untimely process, the lower part of the potted seedling comes into sliding contact with the guide plate 33 and is prevented from coming out, thereby increasing the holding power of the potted seedling by the finger and the holding needle. strengthened. Then, when the bottom of the seedling almost reaches the rice field surface, the planting fork 22 descends to push the potted seedling into the rice field surface and plant it in a predetermined proper posture. During this planting, the seedling guide claws 23 guide the seedlings to a predetermined posture. Then, the planting machine 15 moves upward along a predetermined trajectory and moves downward 1111j again to the position from which the seedlings are taken out, repeating the same movement, thereby continuously planting the seedlings.

When one row of seedlings has been taken out by moving the seedling platform 13 left and right, the seedling conveying belt 25 feeds the potted seedling sheet by one potted seedling. The seedling sheet is reliably prevented from floating up by the seedling guide rod 32, the work of taking out the seedlings by the planting body 15 is made more reliable, and the taking out position and the planting position are more accurate.

The pot seedling planting device of the present invention can be used not only as a walk-behind rice transplanter, but also for transplanting seedlings with soil, such as rice bran.

Thus, according to the present invention, it is possible to reliably hold and separate the potted seedlings from the potted seedling sheet on which the adult seedlings have been grown, and to plant them in the field in an accurate posture. It can be placed on the seedling stand of a well-known rice seedling machine for planting mats, and can be used as is by simply separating the body for planting and replacing the claws for planting, making it highly versatile.
