DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanting plant which includes a seedling table for reciprocating movement to the left and right, and a planting claw for taking out and planting a seedling of one strain from the seedling table. The present invention relates to a planting device for a machine.

[0002]

2. Description of the Related Art Conventionally, Japanese Unexamined Patent Publication No. 60-199309 is disclosed.
Alternatively, as disclosed in Japanese Utility Model Publication No. 56-21212, a technology has been developed in which a rotary case is provided that rotates at a constant speed in one direction, and planting claws are disposed symmetrically about the rotation axis of the rotary case.

[0003]

In the above prior art, interference between the planting claw and the rice field surface can be prevented by stopping the front planting claw from the time of cutting the seedling to reaching the rice field surface. The seedlings cut off by the planting nails are easy to fall off, and by stopping the front planting nails before cutting the seedlings, the stop position of the rear planting nails is extremely low, so that the rear planting can be planted on ridges etc. There was a problem that the claws collided and were easily damaged.

[0004]

According to the present invention, there is provided an apparatus in which a planting claw is attached via a claw case to a rotary case which rotates in one direction at a constant speed. the planting claw of the way after you disposed symmetrically while stop configured to be capable of stopping at a high position than the already Uenae length, so that the planting Tsuketsume tip than the bottom surface of the planting case that So設the rotary case is upwards to the the planting claw configured to stop, seedling taking out further from the both sides seedling blocks sandwiched between pushing pawl in the planting claw of the front has been stopped between leading after load platform seedlings cut seedlings paddy which was constructed as sandwich the guide, with planting claw at planting stroke ends can be prevented from disturbing the paddy projects into the soil, by stopping the rear of the planting claw above the already Uenae , Nails to plant the last planted seedlings or nail cases to attach them The planting work can be stopped more safely than before, the planting operation can be completed more safely than before, the occurrence of stock loss due to the lodging and floating of the planted seedlings can be reduced, and the planting claw tip is higher than the planting case bottom. Even if the float is damaged due to foreign matter colliding with the lower surface of the planting part, the planting case can protect the planting claws, reducing the damage range in case of an accident and simplifying repair. Further, it is possible to prevent the falling of the seedlings held between the forward planting claws and the pushing claws at the time of stoppage by the seedling removal guide, and to eliminate the occurrence of lack of stock at the time of restarting planting.

When the planting stop operation is performed via the clutch lever (43), the eccentric pin (45) comes into contact with the upper stop cam (41) to disconnect the unit clutch (42). As described above, the planting claw (17) on the front side is stopped in the seedling removal guide (56) above the float (34), and the falling of the seedling that is cut and held by the planting nail (17) is used as a seedling removal guide. (56) to prevent the occurrence of stock-out when restarting planting and to float the planting claw (17) on the rear side with the float (3).
4) The seedling is stopped at a position higher than the upper end of the last planted seedling (57) to prevent the planting claw (17) from rushing into the rice field and disturbing the rice field. ), And prevent the planting nail (17) or the nail case (22) from falling down in contact with the already planted seedling.

[0014]

As is apparent from the above embodiments, the present invention relates to an apparatus in which a planting claw (17) is attached via a claw case (22) to a rotary case (21) that rotates at a constant speed in one direction. wherein while configured to stop the planting claw (17) of the way after you disposed symmetrically about the rotation axis at a high position than the already Uenae length to the rotary casing (21), rotary case (21) was constructed as pawl (17) distal planting than the bottom surface of the planting case (20) to So設stops the planting claw (17) so that the upward, further seedling mounting table (1
6) The seedling blower which is clamped by the pushing nail (17a) to the front planting nail (17) stopped from the cutting of the seedling to the rice field surface.
The seedling removal guide (56) sandwiches the seedlings from both sides.
7) can be prevented from entering the soil and disturbing the rice field, and the last planting seedling (57) can be planted by stopping the rear planting claw (17) above the planted seedling (57). Pushing down with the nail (17) or the nail case (22) to which the nail is attached can be prevented, and the planting operation can be completed more safely than in the past. Since the occurrence can be reduced and the tip of the planting claw (17) stops above the planting case (20) bottom surface, foreign matter collides with the lower surface of the planting part (15) and the float (34) is damaged. Even so, the planting case (20) can protect the planting claws (17), reduce the damage range in the event of an accident and simplify repairs, etc., and furthermore, the planting in front of the plant when stopped. Claw (17) and push claw (1
The seedling removal guide (56) prevents the falling off of the seedlings clamped by 7a), thereby making it possible to eliminate the occurrence of stock deficiency when planting is resumed.
