Description

[Detailed description of the invention] This invention is a feed-out roll for seed and powder fertilizer.
The machine is mounted so as to be rotatably switchable between a first mounting direction in which one of seed dispensing recesses and fertilizer dispensing recesses provided in a circumferential direction on the circumference acts, and a second mounting direction in which the other acts. The present invention relates to a feeding device for a rice transplanter with a seeding/fertilizing device that is interlocked and connected to a seedling planting pawl drive member via a type interlocking mechanism so as to be rotated back and forth within a certain angular range as the seedling planting pawl drive member operates.

In the above-mentioned rice transplanter, conventionally, in order to switch the feeding roll from one of the first mounting orientation and the second mounting orientation to the other, the feeding roll is pulled out from the feeding tube, the vertical direction is changed, and the feeding roll is assembled into the feeding tube. However, changing the mounting direction was time consuming.

The purpose of the present invention is to modify the feed roll so that the mounting direction of the roll can be easily changed.
