苗ケースの土付き苗を反転した苗ケースから一株ずつ突
落し圃場に植込むことは従来公知である。It is conventionally known that seedlings with soil in a seedling case are dropped one by one from an inverted seedling case and planted in a field.
この方法では、土付き苗はその葉先を下方にして突落さ
れるため、田地表面に落下し゛た土付き苗の植込みが不
確実になり、その後の生育が不良であるので、突落した
土付き苗の毛根部を確実に先に着地させることが要求さ
れている。In this method, the seedlings with soil are dropped with their leaf tips facing downwards, making it difficult to plant the seedlings with soil that have fallen onto the field surface, and their subsequent growth is poor. It is required to ensure that the hairy roots of the seedlings land first.
本発明の目的は、反転した苗ケースから突落した土付き

って植付けられる。The operation of the device will be explained below. The seedling case 2a on the stacking stand 6 is placed on the feed belt 8 with the tips of the seedlings 1a with soil therein facing downward. The placed seedling case 2a is sent on the seedling case feed table by power transmission from the engine, and the seedlings 1a with soil inside the seedling case 2a, which are sent below the protruding crank 14 that works at the required speed, are transferred to the seedling case 2a. The seedling is thrown down by the protruding rod 18 passing through the bottom hole 3 and falls with its leaf tip downward into the guide tube 31 located below the protruding rod 18, and the hair root part of the seedling falls downward in the slanted bottom plate part 32 of the guide tube. The lower end part 33 of the guide tube is turned over so that the hair root is facing down.
It is received on the seedling stopper 35 of. The seedling IC on the seedling stopper 35 then has a wedge-shaped opening piece 39 that fits between each pair of opening protrusions 38 and 38 protruding from the left and right outer surfaces of the lower end 33 of the guide tube to open the lower end 33 of the guide tube. It is planted by a presser claw inserted into the lower end portion 33 of the guide tube from the opening 40 in synchronization with the above.

収容室内に一枚ずつ積重ねられる。The tip of the empty case 2b that has dropped the seedlings with soil reaches the empty case tip holder 30, but when it is further pushed out by the succeeding seedling case 2a, the tip reaches the horizontal support section 24 of the seedling case feeder.
Since the empty cases 2b are notched, the empty cases 2b fall downward due to their own weight, and are stacked one by one in the empty case storage chamber by the holding frame 28 and the outer frame 29.
本発明によれば、育苗された土付き苗を有する苗ケース
を裏返し状で搬送装置上に載置するだけで、土付き苗を
自動的に確実に植込むことができる。According to the present invention, the seedlings with soil can be automatically and reliably planted by simply placing the seedling case containing the grown seedlings with soil upside down on the conveying device.

に植付けられる。11 is a side view for explaining the structure and operation of the apparatus for planting seedlings, and FIG. 12 is a plan view taken from the line X--X in FIG. 11 in the direction of the arrow. The seedling planting device 41 has a planting arm 43 having at its rear end a seedling scissor claw 42, 42 and a wedge-shaped opening piece 39, 39 that fits between the opening projections 38, 38 at the lower end of the guide tube. For planting, arm 43 is
At its intermediate portion, it is rotatably attached to a crank pin 46 of a drive crank 45 whose crankshaft is supported by a support plate 44 fixed to the rice transplanter in the front-rear direction of the rice transplanter, and at its rear end 47. is rotatably connected to a free end 49 of a swing arm 48 attached to the support plate so as to swing in a plane substantially parallel to the plane of rotation of the crank arm of the drive crank 45. In the figure, 50 is a chain wheel for rotating the crankshaft of the drive crank 45. When the drive crank 45 rotates clockwise (in FIG. 11) as the rice transplanter advances, the wedge-shaped opening piece 39
．． 39 and the seedling scissor claws 42, 42 act almost simultaneously on the opening protrusion 38, 38 at the lower end of the guide tube and the seedlings 1c, ensuring that the seedlings supplied at intervals to the lower end 33 of the guide tube are planted one after another. It will be done.
