Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seedling-raising seeding machine that sows seeds while continuously transporting seedling-raising boxes.

(Prior art) A seedling seeding sowing machine has a frame installed on a transfer mechanism that continuously transports seedling boxes, and a feed roll is rotatably supported on this frame around a horizontal axis, and is fed out in synchronization with the transfer of the seedling boxes. The roll is configured to be rotated to drop and supply rice seeds from a feeding recess of the feeding roll onto the floor of the seedling box. , a nine-figure shape or a concave shape are alternatively used.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, it is not possible to change the delivery roll to a delivery roll with a different shape of the delivery recess without removing the roll shaft or disassembling the roll from the frame. Therefore, it was extremely difficult to change the sowing pattern with a single seeding machine.

(Means for Solving the Problems) The present invention supports the feeding roll 7 in a cassette case 26, making the cassette case 26 freely insertable and removable into the frame 4 of the sowing m1, and in an inserted state, the feeding roll 7 is supported by a cassette case 26. By configuring it to be rotationally driven, the problems of the prior art described above can be solved.

That is, the specific structure of the problem-solving means of the present invention is characterized in that the sowing machine frame 4 is mounted on the support frame 11 of the transfer mechanism 8 for transferring the seedling growing box 13, and this frame 4
A hopper 5 is attached to the frame 4, and a drive mechanism 9 is disposed inside the frame 4, and a delivery roll 7 is driven by the drive mechanism 9 and supplies the seed rice 16 received from the hopper 5 into the seedling box 13 passing below the frame 4. In the arranged seeding machine, the feed roll 7 has a roll gear 27 on the side and is rotatably supported by a cassette case 26 via a roll shaft 29, and this cassette case 26 is connected to the support frame 11.
