Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for receiving empty trays in a seedling transplanting machine for transplanting seedlings such as vegetables one by one into a field.

[0002]

2. Description of the Related Art Generally, when transplanting seedlings such as vegetables to a field, as shown in FIGS. 1 and 2, a large number of soft synthetic resin sheet pots a are integrated into a vertical and horizontal grid pattern. After using a tray A that is continuously connected to each other and growing one plug seedling in each pot a in this tray A,
For example, as described in Japanese Utility Model Laid-Open No. 2-127105 and Japanese Utility Model Laid-Open No. 3-108314, this tray A is loaded in a traveling type seedling transplanter such that it can be fed longitudinally and laterally, The plug seedlings in each pot a in the tray A are picked up from inside the pot a by the nail body of the seedling transplanter and transplanted to the field scene.

[0003]

However, since the above-mentioned tray is made of a soft synthetic resin sheet, it is easily deformed. Therefore, in the conventional seedling transplanting machine, the plug seedlings after being extracted from each pot are removed. The empty tray is designed to be discharged from the seedling transplanting machine to the field scene. For this reason, the empty trays discharged from the seedling transplanting machine to the farm scene must be collected so that they can be collected one by one later. There is a problem in that the released seedlings often damage the transplanted seedlings when they are released and when the empty trays released in the field fly by the wind.

In order to solve this problem, it is a technical object of the present invention to provide a device capable of sequentially receiving empty empty trays in a seedling transplanter. is there.

[0005]

In order to achieve this technical object, "claim 1" in the present invention is "an empty tray in a seedling transplanter using a tray made of a soft synthetic resin sheet having a large number of pots. A guide member extending in the discharge direction of the empty tray is attached to the discharge part of the
A support body that supports the tip of the empty tray from its lower surface side is slidable along the longitudinal direction of the guide member, and biases the support body toward the discharge portion of the empty tray. On the other hand, an empty tray receiving box is provided below the guide member. "."

According to the "claim 2" of the present invention, "the left and right side edges of the empty tray are fitted to the empty tray discharge part in a seedling transplanter using a tray made of a soft synthetic resin sheet having a large number of pots. A pair of left and right guide bodies having a round guide groove are attached so that the guide grooves in both guide bodies are inclined obliquely upward, while a receiving box for an empty tray is arranged below these guide bodies. " I made it a structure to say.

Further, the "claim 3" in the present invention is
"In the discharge section of the empty tray in the seedling transplanter using a tray made of a soft synthetic resin sheet with a large number of pots, a pair of left and right rotary shafts extending in the discharge direction of the empty tray are rotatably disposed, A plurality of receiving vane plates are provided on each of the two rotating shafts so as to extend in the axial direction of the rotating shafts, and a stopper body that abuts the lower surface of the receiving vane plates on both the rotating shafts is provided between the ends of the rotating shafts. , Is provided so that it can be moved backward, and a spring for urging the stopper body to receive the stopper body toward the blade plate is provided on the stopper body, while an empty tray receiving box is provided below the both rotary shafts. I made it a structure to say.

Furthermore, "claim 4" in the present invention
Says, "In the empty tray discharge part in a seedling transplanter that uses a tray made of soft synthetic resin sheet with many pots,
A pair of left and right guide rods having guide grooves into which the left and right side edges of the empty tray are fitted are arranged so that both guide rods extend in the discharge direction of the empty tray, and both guide rods are

[0009]

[Operation] In the above-mentioned "claim 1", when the empty tray sent out from the empty tray discharge portion of the seedling transplanter comes into contact with the support member slidably provided on the guide member, This support follows the feeding of the empty tray and moves backward while supporting the front end of the empty tray, and eventually, when the entire empty tray is fed from the discharge section, the empty tray is , By dropping and entering the receiving box disposed therebelow, the support returns repeatedly toward the discharging section,
It is possible to receive the empty trays sent out from the discharge section so as to be sequentially put in the receiving box.

In the above-mentioned "Claim 2", the empty tray sent out from the empty tray discharge part in the seedling transplanter has a pair of left and right guide bodies on the left and right edges of the empty tray. It will fit in the guide groove. In this case, the empty trays are curved so that their cross sections are upward convex by inclining the guide grooves in both guide bodies obliquely upward.
Due to this bending, the empty tray becomes straight, so that it is sent out along both guide bodies without drooping from both guide bodies, and then the next empty tray is fed between both guide bodies. At this time, the next empty tray is pushed out from both guide bodies and falls, and then repeatedly enters the receiving box disposed below the empty guide tray, so that the empty tray sent out from the discharging section is You can receive them by putting them in the inbox one by one.

In addition, in the structure of claim 3,
The empty tray sent out from the empty tray discharge part of the seedling transplanter is sent out with both left and right edges of the empty tray supported on the upper surfaces of the receiving blades of both rotary shafts, and eventually the tip of the empty tray is a stopper body. The stopper body retracts against the spring and comes off from the end of the receiving blade plate on both rotary shafts.
Since the weight of the empty tray placed on the upper surface of the receiving vane plate in each of them rotates inward, the empty tray falls and enters the receiving box disposed therebelow, while the stopper body is By repeatedly returning to the state in which the spring is engaged with the next receiving vane plate on both rotary shafts, the empty tray sent out from the discharge section is
It can be received by sequentially putting it in the receiving box.

Further, in the structure of "Claim 4", the empty tray sent out from the empty tray discharging portion of the seedling transplanter has a pair of left and right side edges on the left and right sides of the empty tray. It fits in the guide groove in the guide rod, and in this state, it is sent out along both guide rods. In this case, since both guide rods are attached to the body of the seedling transplanter via a parallel link mechanism, when the tip of the empty tray eventually comes into contact with the stoppers at the ends of both guide rods, both guide rods are attached. Open outwardly from each other and move away from the left and right side edges of the empty tray, the empty tray falls and enters the receiving box disposed below the empty tray, while the guide rods are returned by their return springs. By repeating the return to the original state, the empty trays sent from the discharging section can be received so as to be sequentially put in the receiving box.

[0013]

As described above, according to the present invention, when transplanting seedlings by the seedling transplanter, empty trays discharged from the seedling transplanter can be sequentially received in the receiving box attached to the seedling transplanter. Since it is possible to eliminate the trouble of collecting empty trays discharged to the field scene as in the past, it is possible not only to significantly improve the work efficiency but also to reliably reduce the damage to the transplanted seedlings by the empty trays.
