いから、その条数の変更等がきわめて厄介であった。A conventional multi-row rice transplanter is attached to a traveling machine body, and from a feed case with a built-in horizontal and vertical feed mechanism for the seedling platform, multiple transmission cases with seedling planting claws at the tips and ends are connected at appropriate intervals. Therefore, in order to change the spacing between seedling rows and the number of seedling rows between each transmission case, a feed case that is integrally equipped with the transmission case is manufactured each time. Since a plurality of feeding cases equipped with various functions had to be installed in parallel, it was extremely troublesome to change the number of threads.

れば良い)。In summary, the present invention provides a method for connecting and connecting a plurality of seedling planting units 25 each consisting of a transmission case 26 with a seedling planting claw 28 and a float 33 attached to the transmission case. Flange portions 50 and 51 are formed on both sides, and the respective transmission cases are connected by a cylindrical member 55 or 56 whose both ends are removably joined to the flange portion on the opposite inner side. A feed mechanism 61 is formed by inserting and holding a portion integrally protruding from a feed case 62 into a joint between the flange portion and the cylindrical member or a flange joint provided in the middle of the cylindrical member. Therefore, the transmission case and float in each seedling planting unit can be made into the same shape for each seedling planting unit).In other words, each seedling planting unit can be made into a unit with a common shape, and each seedling planting unit) can be made into the same shape. Since it can be joined at both the left and right sides, the seedling planting unit here can be removed from the 6-row planting state shown in the above embodiment and Fig. 10 to be planted in 4 rows as shown in Fig. 9 (in this case, the feeding case 62
If the protruding part of the feed case 62 remains inserted between the flange 50 and the cylindrical member 56 as in the case of six-row planting, the feed case 62 will be eccentric, but it should be installed at the center position. Sometimes, as shown in FIG. 9, flange joints 55' and 55'' are provided in the middle of the tubular member 55,
5' and 55'' by inserting the protruding part of the feeding case 62).

Because they are inserted and held in place, it is possible to assemble the feeding case integrally at the same time as the connection of each seedling planting unit, and it is possible to prevent an increase in the time and space required for assembling the feeding case, and also to prevent the case from protruding from the feeding case. The part is formed into a hollow shape as in the embodiment, and there is an effect that power can be transmitted between the feeding case and the seedling planting unit inside the part.
