The illustrated earth covering member (141) is attached to a side surface of the cam case (125). Its shape is U-shaped in side view,
It is provided in a position that does not interfere with the opening and closing of the planting claws (130) and (131) when curved in a spoon shape in plan view.

A spring plate is used as the covering member (141), and its elastic deformation changes the vertical relative position with respect to the planting claws (130) and (131), and restores the elastic deformation of the covering member. The soil can be covered with force.

FIG. 4 shows an improved take-out claw (62a) (62b), in which the tip of each take-out claw (142) is bifurcated (142c) as shown in FIG. (142d), and furthermore, as shown in FIG.

42b) can rotate freely.

When the extraction nail is formed as described above, not only is it possible to adapt to the softness of the plug seedling by adjusting the width W, but also with the fact that the toe is configured to be forked, a large plug can also be used for seedling removal. Adjustment is also possible depending on the size of the seedling.

(Effects of the Invention) According to the present invention, the planting posture of the seedlings is disturbed because the covering member made of an elastic member having a U-shape in a side view that rotates integrally with the planting claws is provided. And the soil covering member does not interfere with the aerial part of the seedling and the planting nail.

Since the mechanism for moving the soil covering member can be shared with the planting claw, the configuration is simple.

Furthermore, since the operation is similar to the planting trajectory, there is a feature that the time for contacting the multi-use vinyl or the like is short and the tear of the vinyl is small. However, since the covering member is formed of an elastic member in a U-shape in a side view, the vertical relative position with respect to the planting claw changes, and the covering can be covered with a restoring force of the elastic deformation of the covering member. Since the soil is covered with the pressing surface instead of being pierced, the possibility of breaking the multi-use vinyl is further reduced.
