たものがある。(Prior Art) In a transplanter for transplanting potted seedlings of vegetables, etc., after loading a seedling box having a large number of pots vertically and horizontally into the seedling box guiding means, the seedling box feeding means is used to put the seedling box into a seedling. It feeds intermittently from the top to the bottom along the box guiding means by one pitch,
The seedlings in the horizontal row of pots of this seedling box are extruded onto the lateral feeding means by the seedling pushing means, and each seedling is supplied to the planting means one by one by the intermittent operation of the lateral feeding means so as to be planted. There is.
第13、14図は、かかる移植機に採用される従来の苗箱
114を示す。Figures 13 and 14 show the conventional seedling boxes used in such transplanters.
114 is shown.

て構成されている。The seedling box 114 is made of a flexible material such as relatively thin plastic, and has a central seedling box body 122a composed of a large number of pots 122 and guide side plates 116 provided on the left and right sides of the seedling box guiding means of the transplanter. The left and right ends 122b that engage with are integrally provided.

Ａ′の送りが阻害されることがあった。(Problems to be solved by the invention) In the conventional seedling box 114, as shown in FIG. 13, the upper surface 122c of the seedling box main body 122a and the left and right end portions 122b are simply formed in a plane, for example, When the seedling A ′ is placed on the seedling box 114 side with respect to the seedling receiving device 163 as shown in the right side of FIG. 13, the bottom side of the seedling A ′ is the guide side plate 116. Of the seedlings A ′ are crushed by being caught on the tip of the pressing portion 116a or the feeding claw 129 protruding from the pressing portion 116a or the seedling receiving member 163.
In some cases, the seedling A may protrude from the seedlings, which hinders the subsequent feeding of the seedlings A ′.

もなる。On the other hand, in order to solve the above-mentioned inconvenience, it is conceivable to dispose the seedling receiver 163 as a whole in a more forward position (in the pushing direction of the seedling A ′). Since it directly receives the seedling A ', it is desirable to place it as close to the pot section 122 as possible. Further, an immovable chute or the like may be provided between the pot part 122 and the seedling receiving device 163, but this makes the mechanism complicated and increases the chances of damaging the seedling A ′.

大であり、また苗受具63相互間で苗Ａを挟む等の惧れも
少ない。As shown in FIG. 8, each seedling support 63 is provided with a bent edge 63a only on one side in the width direction. Therefore, this seedling receiver 6
No. 3 has a larger seedling receiving area than the one having bent edges on both sides, and there is little fear of sandwiching the seedling A between the seedling receiving devices 63.
植付け手段９は昇降自在な植付け筒86を有し、その下
降時に畝１上のマルチフイルム２を溶断した後、作穴し
て苗Ａを植付けるようになっている。なお、この植付け
手段９には覆土兼用の押え輪等が設けられている。The planting means 9 has a vertically movable planting tube 86, and when the planting means 9 is lowered, the multi-film 2 on the ridge 1 is melted and cut, and then a hole is made to plant the seedling A. Note that the planting means 9 is provided with a presser wheel and the like which also serve as soil covering.
この移植機３を用いて苗Ａの移植作業を行う場合に

すれば、第10図に示すように畝１の両肩部に苗Ａを夫々
植付けることができる。When the transplanting operation of the seedlings A is performed by using the transplanting machine 3, the seedling box 14 in which the seedlings A have been raised in the pot portion 22 is loaded into the seedling box guiding means 5 from above, and FIG. 1 and FIG. Each part is operated while running while straddling the ridge 1 as shown in FIG. As a result, the seedlings A in the seedling box 14 can be automatically planted one by one on the shoulders of the ridges 1 by the planting means 9, and therefore, when reciprocating, as shown in FIG. Seedlings A can be planted in each.
移植作業時には、苗箱送り手段６が苗箱14を１ピッチ

各苗Ａを順次植付け手段９の植付け筒86へと供給する。During the transplanting operation, the seedling box feeding means 6 feeds the seedling box 14 downward by one pitch, and after the feeding operation, the seedling pushing means 67 feeds the seedlings A in the pots 22 in a row in the row of the seedling box 14 to the front lateral feeding means 8.
Extrude up. Then, the transverse feeding means 8 intermittently operates seven times for each operation of the seedling box feeding means 6 and the like, and sequentially supplies each seedling A on the seedling receiving device 63 to the planting cylinder 86 of the planting means 9. .

し得るようになる。In this case, according to the present embodiment employing the seedling box 14 described above, the left and right ends 22b of the seedling box 14, the tip of the feed claw 29 at the time of engagement with the feed hole 23 is the upper surface 22c of the seedling box body 22a. Since it is formed so as to be displaced toward the bottom surface side of the pot portion 22 more than the upper surface 22c so as not to protrude further, the lateral feeding means 8 (seedling receiver 63)
Even if the seedling A sent to the machine is misaligned in the anti-extrusion direction due to mechanical vibration or the like, the seedling 14 can be reliably laterally fed without hitting the feed claws 23 and the like, and the seedling box main body 22a and The separation distance between the seedling receivers 63 can be reduced as much as possible, and the seedlings A can be transferred to the seedling receivers 63 more reliably.

る。Further, in the present embodiment, when the drive shaft 53 rotates in the direction indicated by the arrow a, the seedling box feed cam 49 first acts on the cam roller 39, and the feed arm 37 moves upward around the rotary shaft 26 (direction indicated by the arrow b). Since it rotates, the claw portion 33 of the feeding claw 29 engages with the feeding hole 23 of the seedling box 14. When the cam 49 is disengaged from the cam roller 39, the feed arm 37 is returned by the spring 38, so that the feed claw 29 is lowered, and the claw portion 33 engaging with the feed hole 23 pulls the seedling box 14 downward. Therefore, the seedling box 14 is fed downward by one pitch along the seedling box guiding means 5. Further, when the feed claw 29 descends, the regulating claw 31 enters the feed hole 23, but when the feed claw 29 descends to the lower limit, the regulating claw 31 comes into contact with the stopper 35 and is locked. Engage the rim. Therefore seedling box 14
After feeding, since the feeding claw 29 and the regulating claw 31 engage with the feeding hole 23 from above and below, they are positioned at the feeding position, and the weight of the bed soil of the seedling A in the pot portion 22 or mechanical Even if vibration is applied to the seedling box 14, it does not shift up and down, and each pot portion 22 can be surely matched with the pushing rod 40.

40はバネ46によって戻る。When the seedling box feeding operation is completed, the seedling pushing cam 50 acts on the cam roller 47, and the pushing arm 44 turns around the turning shaft 43 (in the direction shown by the arrow c).
Are pushed forward on the guide rods 42, and each push rod 40 is
The seedling A of the pot portion 22 is pushed from the floor soil side and pushed forward. For this reason, a row of seedlings A is simultaneously extruded and placed on each seedling receiver 63 of the lateral feed means 8. After extrusion, push rod
40 is returned by spring 46.

って行く。On the other hand, the transverse feeding means 8 operates intermittently seven times each time they operate once in synchronism with the seedling box feeding means 6 and the pushing means 7, so that the seedlings A on the seedling receiver 63 are sequentially planted. Means 9
Supply to. In other words, the Geneva mechanism 69 is a Geneva wheel
For one rotation of 73, the Geneva gear 71 rotates by four pitches of the seedling receiving device 63, and the gears 52 and 54
Since the large-diameter gear 52 makes one rotation in 3.5 rotations, the lateral feeding means 8 intermittently operates 7 times at 1 pitch intervals for one operation of the seedling box feeding means 6 and seedling pushing means 7. Will be sent in sequence.
そして、全ての苗Ａを押出した空の苗箱14は、苗箱案
内手段５の下端から斜め下方に排出されて行く。The empty seedling box 14 from which all the seedlings A have been extruded is discharged obliquely downward from the lower end of the seedling box guiding means 5.

Since the feeding claws 23 and the like do not project between the 22a and the seedling receiving device 63, they can be brought as close as possible, and the lateral feeding means 8 for the seedling A 8
Can be transferred more reliably.
