BACKGROUND OF THE INVENTION
In this invention, a rice seedling that has been nurtured by laying a rooted sheet such as a non-woven fabric or a thin foamed urethane resin in a hydroponic tank with a predetermined width in the front and back, and seedling seedlings on it is grown. A long mat-shaped seedling wound in a spiral shape so that the seedlings and stems are wound inside is placed on the seedling placement table of the rice transplanter and rewound while the seedling is placed on the seedling placement table. It is related with the rice transplanting device using the long mat seedlings transplanted in.

[Prior art and problems to be solved by the invention]
Conventionally, there has been a rice transplanting apparatus using a long mat seedling disclosed in JP-A-8-319442. In this prior art, long mat seedlings are spirally wound around a roll on a seedling mounting base of a rice transplanter and supplied to the seedling transplanter while being unwound and planted. However, this type of technology has a feature that a considerable area can be transplanted with a single loading of a long mat seedling. However, each seedling is provided with a roller in which the mat seedlings are wound around a seedling mounting table arranged side by side. The seedling roots protruding from the left and right lateral edges of each long mat seedling pivotally supported via a bracket attached to the upper part of the partition frame of the mounting table were entangled, making smooth feeding difficult.

It is configured to be planted in the lower paddy field scene.
[0008]
31 is a leveling float, which is attached to the lower side of the longitudinal transmission case 20c so that the front side can move up and down, and comprises a center float 31a and side floats 31b and 31b. At each of these floats, the seedling planting field is leveled, and seedlings are planted in that area.
No. 32 is a long mat seedling wound in a roll, and a root sheet 33 such as a non-woven fabric or a thin foamed urethane resin is laid in a hydroponic tank long in the front and back with a predetermined width. Paddy rice seedlings that have been grown by thickening seed pods are wound into a roller 34 in a spiral shape so that the stalks are wound inside to facilitate transportation, etc., and this is loaded onto the seedling mounting table 21 of the rice transplanter. And use it. In a specific embodiment, the rollers are provided on a rotary arm 36 with a handle 35 via brackets on the left and right frames (including the partition frame) of each of the seedling mounting bases 21 that are partitioned in the left and right directions. 34 is provided with a fitting hole 38 that rotatably supports a support shaft 37 that protrudes from the left and right sides of the support 34, and the support shaft 37 is inserted into the hole 38 to form a spiral on the seedling mounting table 21. The seedling 32 is supported as a support.
[0009]
The bottom end of the outer periphery of the long mat seedling 32 is brought close to the upper surface side of the transfer belt 22 of the seedling mounting table 21 so that the seedling mounting table 21 is fed out when the left and right lateral ends are turned back. As a configuration in which the lower end of the outer periphery of the mat seedling 32 is held close to the seedling mounting table 21, a receiving member 40 biased upward by a spring 39 is configured on a side frame portion of the seedling mounting table 21 via a support rod 41. ing. Reference numeral 42 denotes a roller for pressing the leaf stem portion of the seedling 32 to be placed. The rotating arm 36 can be freely rotated to the rear side as indicated by the phantom line in FIG. 1 so that the seedling 32 can be easily replaced.
[0010]
Reference numeral 43 denotes a partition, which is a front / rear intermediate portion of the partition frame 21a located at the left / right intermediate portion of the seedling mounting table 21, and a portion on which a roller 34 that winds the long mat seedling 32 in a spiral shape is supported. Are provided so as to partition the supported long mat seedlings 32, 32,. That is, the partition 43 divides the adjacent portions of the long mat seedlings 32 that are mounted on the seedling placement bases 21 in the rolled-up state, and the seedlings protrude from the left and right edges of the long mat seedlings 32. It is configured so that the roots do not entangle with each other.
[0011]
As another embodiment, as shown in FIG. 5, the partition body 43 has a disk shape, and the disk-shaped partition body 43a is rotatably provided on the support shaft 37 of the roller 34. The long mat seedling 32 to be combined is partitioned. The disk may be fixed to the support shaft 37 and rotated together with the roller 34. In the case of the partition body 43a, a slit 44 into which the disk sinks is required in the partition frame 21a of the seedling placement table 21, and the partition body 43a is fitted into the slit 44.
[0012]
The long mat seedling 32 wound around the roller 34 in a spiral shape is loaded on the seedling mounting table 21 in a state of being rotatably supported by the arm 36, and the lower side of the long mat seedling 32 is placed on the transfer belt 22. The seedling planting device 28 is replenished by placing it on the upper surface. At this time, since the partition body 43 is erected on the partition frame 21a, the left and right side edges of the long mat seedlings 32 adjacent to each other are kept loaded without interfering with each other.
[0013]
In this state, when each part of the rice transplanter 19 is driven while propelling the traveling vehicle body 1, the seedling placing table 21 reciprocates horizontally to the left and right, and the long mat seedling 32 is received by the transfer belt 22 and reaches the left and right lateral ends. The belt 22 rotates to the rear side, and the rear end portion of the long mat seedling 32 is received by the seedling receiving frame 26 and fed to the seedling dividing port 27. That is, since the seedling placing table 21 moves to the left and right sides, the long mat seedling 32 is fed from the lateral direction to the seedling dividing port 27.
[0014]
The long mat seedlings 32 fed out to the seedling dividing port 27 are divided and held by the planting claws 30a of the seedling planting device 28, and planted one after another in the paddy field field leveled by the lower leveling float 31. In such a seedling planting operation, the long mat seedling 32 mounted on the seedling mounting table 21 is unwound and supplied to the seedling planting device 28 because the partition 43 separates the adjacent parts. Further, there is no interference between adjacent long mat seedlings 32, and each long mat seedling 32 is reliably rewound by the transfer belt and supplied.
[0015]
When the long mat seedling 32 is rewound, when the long mat seedling 32 is rewound, it is rewound smoothly and supplied to the planting device 28 when the long mat seedling 32 is rewound.
When the long mat seedling 32 is brought into contact with the upper surface of the seedling placing table 21 and fed out, smooth feeding and replenishment are difficult when the contacting pressure is not appropriate. As a means to solve this problem, A -該A fulcrum of arm 36 and (b) on the opposite side - provided 44a, the lever - - integrally shaped lever to arm 36 selects the weight 45 to 44a, allowing desorption balance It may be configured to keep Thereby, it is possible to easily cope with the growth state and water absorption state of the long mat seedling 32. Of course, the length of the lever 44a from the fulcrum (A) may be changed and adjusted without selecting and detaching the weight 45. In this case, the length of the lever 44a can be expanded or contracted. What is necessary is just to change the axis | shaft which attaches 45 back and forth.
[0016]
[Effects of the invention]
According to the invention, b long mat seedlings each seedling mounting table - if placed on the rewind state through the La and Ru is supplied to the seedling planting apparatus, the partition member is fitted in slits, each seedling The seedling roots protruding from the left and right lateral edges of the long mat seedling placed on the mounting table are held by the partitioning body without being touched, and are smoothly rewound without resistance. The seedlings can be reliably supplied without being strained or stretched, and the variation in the number of seedlings can be reduced. In addition, a lever integrated with the arm is provided on the side opposite to the fulcrum of the arm, and the lever is configured to be able to attach and detach the weight or extend and retract from the fulcrum so that the balance can be maintained. It is possible to easily cope with the growth state and water absorption state of the long mat seedling.
