Description

The present invention relates to a piercing tool for planting, and is devised so that bulbs such as taro and potato can be planted comfortably on a ridge covered with a covering film such as a multi-film.

As a piercing tool for planting root crops and bulbs such as taro and potatoes on the ridge covered with the multi-film, it has a cylindrical shape at the time of uniting and has a cylindrical body consisting of a pair of half cylinders divided vertically. A pair of semi-cylindrical members is connected by a pivot and a gear at the upper end side, and is known to be rotatable by a handle operation (see Patent Document 1). At the time of perforation, the semi-cylindrical body is united into a cylindrical shape, and the handle is grasped with a hand, and the multi-film is addressed to the ridge. As a result, the cylinder breaks into the soil while breaking the multi-film. When the boring tool is pulled up after a predetermined depth in the soil is obtained, a hole is formed in the soil because the soil remains in the cylinder. Bulbs such as taro and potato are put in this hole. On the other hand, the half-cylinder is expanded by operation on the grip side, and the soil retained therein can be used to refill the hole.
