Finally, the case where the above-mentioned walking type seeding machine 1 is used as a vegetable seedling transplanting machine to transplant seedlings into a cocoon will be described.
First, the seed tank 58 is emptied, and the seed supply cup 40a is removed from each supply cup 40. In addition, the seed planting tool 60 of the planting device 5 is replaced with a general seedling planting tool 60 ′ that can be transplanted with cell-shaped seedlings. Then, two seedling trays on which the seedlings are grown on the seedling stage 55 and in which the seedlings are placed in each seedling pot section are arranged side by side in the left-right direction.

  Then, the main clutch lever 204 is turned on to move the left and right front wheels 3 and left and right rear wheels 2 along the ridges, and the planting lift lever 203 is operated to turn on the planting clutch and control the body. With the mechanism in a controlled state, the operator walks through the space A on the left side of the machine body (the rear groove of the left rear wheel 2), and turns the seedlings on the seedling tray placed on the seedling placing stand 55 on the turntable 41. To each seedling supply cup 40. Then, when each seedling supply cup 40 containing seedlings is rotated to the seedling supply position P by the rotation of the turntable 41, the shutter 52 opens and the seedlings fall into the seedling planting tool 60 'of the planting device 5. Then, after the seedling planting tool 60 ′ has planted the seedling in the cocoon, the pair of left and right pressing wheels 180 and 180 lightly press the left and right sides of the seedling. At this time, the operator can replenish seedlings in an easy posture from the space A on the left side of the machine body to the seedling supply cups 40 of the turntable 41, and the work efficiency is safe and high.

  In addition, in the said Example, although the example of an operation | work which seed | inoculates a seed or transplants a seedling was shown, it is the same also when seeding or transplanting a seedling to a flat farm field. In addition, seeds such as coated seeds of beans and vegetables may be sown for sowing work, and seedling transplanting work such as seedlings of leaf vegetables such as cabbage and Chinese cabbage, seedlings of root vegetables such as radishes and sweet potatoes, nanban and saiban Other seedlings such as grass or flowers may be used.
