Description

  The present invention relates to a planting machine technique, and more particularly to a planting machine technique for planting seed balls in soil covered with a multi-sheet.

  Conventionally, seed balls such as garlic have led to a decrease in yield and grade due to poor germination, etc., unless planted so that the seed ball buds are on top and the seed ball roots are on the bottom. . Therefore, in order to harvest high-quality crops, we had to manually plant seed balls.

However, in the case of commodity crops, manual labor has been a heavy burden on workers due to the expansion of the cropping area. For this reason, a number of planting machines for planting seed balls in the field have been proposed.
For example, as shown in Patent Document 1, a seed ball holder unit composed of a planting holder and a push-in body is attached to an orbiting movement mechanism, and the orbiting movement mechanism rotates and the seed ball holder unit rotates. The planting holder is configured to hold a bulb such as garlic and plant the bulb by pressing it against the field with a pusher while moving to the planting position by the orbital movement mechanism. In the insertion position where the bulb is inserted into the planting holder, the planting holder is located in the upper part of the seed ball holder unit, and in the planting position, the planting holder is located in the lower part. Therefore, the direction of the bulb was upside down between the insertion position and the planting position.
In addition, a planting hole is provided in a multi-film (multi-sheet) in advance, and a technique of a planting machine that matches the planting position of the bulb by detecting the position with a sensor attached to the airframe is known. ing.
