Here, in FIGS. 1 to 3, the invention according to the first aspect of the present invention is described in detail. As a configuration of a plant crushing device of a seedling planter, which is provided with a crushing wheel 2 for bringing the soil surface A to the inside of the inside of the beak 1 on the inner side, The plant is pierced into the surface A to form a planting hole in the soil surface A, and the held seedling is planted in the planting hole. When the planting beak 1 plants a seedling in the planting hole, the crushing wheel 2 on the side of the planting position B pulls the soil toward the planting beak 1 at the planting position B, and the planting beak 1 When the seedlings are removed upward, the planting holes in the traces where the seedlings have been planted are crushed from both the left and right sides to the center, thereby crushing the seedlings, thereby fixing the planting posture of the seedlings. Therefore, it is possible to reduce seedling disturbance such that seedlings that are planted adhere and rise as the planting beak 1 rises, and stable seedling planting can be performed.

Here, the pair of left and right pressure-reducing wheels 2 are provided rotatably around a shaft 30 at the tip of an arm 29 provided rotatably up and down around an arm shaft 28 with respect to the handle frame 13. . The compression ring 2 is formed in an oblique shape so that the lower end contact portion approaches the left and right side surfaces of the lower end of the planting beak 1 as much as possible.

1 can be fixed. The crushing position of the crushing wheel 2 can be adjusted by the height of the ridge C, the planting depth, and the like. This arm 29 can crush the soil surface A by its own weight of the crushing wheel 2, but it may have a structure in which a spring can be provided to crush the soil surface by springing. Thus, the arm 29 may be configured to be capable of intermittently lowering the pressure at a certain timing at the same time when the planting beak 1 is planted.

In the seedling planting operation, when the planting beak 1 pierces the soil surface A as shown in FIG. 2A, the soil surfaces A on both the left and right sides are crushed by the crushing wheel 2. When the planting beak 1 inserted in the soil surface A is opened back and forth, a planting hole E is formed, and the seedlings G held in the planting hole E are dropped and planted, and both right and left sides are formed. And press it against the root of the seedling G in the planting hole E.

In this state, since the planting beak 1 is moved upward with the planting beak 1 open as shown in (2), the planting hole E in which the seedlings G on the trace of the planting beak 1 being raised are placed. The soil surface A is pushed in so as to be buried from both right and left sides. For this reason, since the soil cover pressure by the compression ring 2 acts on the root part of the planting of the seedlings G, the seedlings G do not adhere to the planting beak 1 that is withdrawn upward and are not disturbed. The planting posture (3) of G can be maintained.
