Therefore, as disclosed in Japanese Unexamined Utility Model Publication No. 57-100833, the upper part of the upper path of the seedling feeding belt is retracted to the back side of the seedling stand by manual operation via a wire, thereby preventing the mat-shaped seedlings from slipping and falling. Measures have been proposed to make it easier.

The characteristic configuration of the present invention is that a guide for feeding seedlings is arranged along the lateral side of the upper path of the seedling feeding belt, and this guide is attached to the seedling stand so as to be able to swing freely around a horizontal fulcrum in the middle of the guide. It is located at a certain point, and its functions and effects are as follows.

In other words, if a sufficient amount of cloak-like surface is placed on the seedling-resting surface of the seedling-resting stand, the moment due to the load of the mat-like seedlings will be above the upper part of the guide for feeding seedlings, and the guide will be attached to the seedling feeding belt. It maintains a posture along the side of the upper path of the guide, and a projection protruding upward from the guide acts on the lower surface of the mantle-shaped surface. Next, when the mantle-like surface on the seedling stand is used and its upper end decreases to near the fulcrum of the mantle-like surface, the moment acting on the guide part above the horizontal fulcrum acts on the guide part below. The moment becomes smaller, and the guide swings around the horizontal fulcrum, causing the upper guide portion to rise slightly and the lower guide portion to sink slightly. As the upper guide part lifts up, the protrusion of the seedling feeding belt relative to this guide part becomes relatively small, and even if the cloak-shaped replenishment surface slides down from the top of the seedling stand, the raised upper part will not be removed. Since it slides on the guide part, the protrusions no longer act strongly and the cloak-like surface can be refilled smoothly. When the mat-like seedlings are replenished to a certain extent, the moment due to the load on the mantle-like surface rotates upwards above the guide, and the guide returns to its normal position, and the protrusions along the entire upper path once again fully act on the mantle-like surface. .

Therefore, according to the present invention, the load of the cloak-like surface remaining on the seedling stand is used to float above the seedling feeding guide, so that no manual operation is required when replenishing the cloak-like surface. Moreover, since it has a simple structure in which the guide is only pivotally attached to the seedling stand, it can be constructed at low cost, which is advantageous in practice.

As shown in FIG. 4, the width center of the seedling surface (1a),
That is, between the left and right seedling feeding mechanisms (3), a strip-shaped guide (7) for feeding seedlings is arranged along the lateral side of the seedling feeding belt (6). As shown in Fig. 1, this guide (7) is capable of swinging the scale around a horizontal fulcrum (X) in the middle in the longitudinal direction, and has a protrusion ( It is pivoted to the seedling stand (1) so that it is lower than 6a). A switch (SW) is provided on the back side of the lower part of the guide (7) to detect that the lower end of the guide (7) has come into contact with the seedling placement surface (1a). This switch (SW) is linked to an alarm device (not shown) of the operating section (not shown).
