(Prior Art) Conventionally, as a means for punching a planting hole for transplanted seedlings by a transplanter in a multi-sheet stretched on the surface of a ridge, a planting hole is formed in the multi-sheet by heating and burning using a gas burner. There are a type of punching and a type of punching the sheet in a tear-like shape by utilizing the operation of driving the nail into the soil by the implanting nail itself.

(Problems to be solved by the invention) However, in the former case described above, the moisture contained in the soil evaporates with the passage of time after the multi-sheet is stretched, and becomes a water drop and adheres to the back surface of the sheet. Therefore, the heating temperature of the gas burner that is going to burn out the sheet is lowered, and burnout of the sheet becomes difficult, or the multi-sheet of the resin-based material is toxic gas when heated by the gas burner. There was a problem that it occurred and adversely affected crops and workers.

Further, in the latter case described above, the planting holes are not cut into holes in the multisheet, but are torn at the tip of the transplanted nail in a tearing manner, so the multisheet is pulled into the soil at the time of tearing. Other seedlings to be transplanted, or the tear piece of the sheet remains after the transplant nail is withdrawn, the tear piece covers the upper surface of the transplant seedling or is embedded in the soil together with the transplant seedling. However, there is a problem that the transplanted seedlings are adversely affected.

The present invention has been devised in view of the above-mentioned problems in the prior art, and its purpose is to cut out a circular shape by using the rotation of the rotary blade under the condition that the multi-sheet is pressed and to make a hole. In this way, a circular planting hole can be surely punched in the multi-sheet without pulling the multi-sheet to pull down other transplanted seedlings, and the punching piece is used for the drilling. It is an object of the present invention to provide a multi-cutter for a transplanting machine which is collected at the same time as the drilling work and does not hinder the growth of transplanted seedlings due to the remaining of the drilled pieces on the traces of the drilled holes.
