Since the first example of the prior art is manually performed, it is a problem in terms of labor saving and is inefficient.
Not only against mechanization, but also when the adhesive force to the pot is high, there is a risk of the shape being deformed because the finger is pressed. Conventional example 2
Although 3 and 3 are advantageous in terms of labor saving and mechanization, 2 of the conventional example is one in which the seedling frame is curved, intermittently fed, and projected by an extruding tool, so that the seedling frame is durable by repeated bending deformation. However, there is a problem that the extrusion timing is apt to be misaligned and the leaf portion of the seedling is easily bent and damaged. On the other hand, the conventional example 3 has a problem in that the piercing member comes into contact with the leaf portion to cause frequent damage because the piercing member is pushed down from the leaf portion side.

Further, in both the conventional example 2 and the conventional example 3, the soil-grown seedlings are taken out in a state where the seedling frame is attached to the transplanter, so that a so-called empty box seedling frame is dropped in the field. And there was a common problem that the collection work was troublesome. It is an object of the present invention to provide a method for taking out soiled seedlings, a device for taking out soiled seedlings, and a soiled seedling feeding device that solve the above-mentioned problems.
