Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a preliminary seedling resting tool above an inclined seedling resting table of a seedling planting device, and uses this preliminary seedling resting tool to hold the preliminary seedlings approximately horizontally. Place it in a posture and place it in a posture and! ! The present invention relates to a spare seedling feeding device for a seedling planting device that is configured to be able to switch between an inclined position and an inclined position in which placed spare seedlings are fed downward.

[Conventional technology]

As disclosed in Japanese Patent Publication No. 62-5561, a preliminary seedling feeding device for this type of seedling planting device is such that a roller is provided below the preliminary seedling holder, and the preliminary seedling holder is placed at a high position. When the placement position is changed to a lower inclined position, the roller protrudes from the hole formed in the seedling placement surface and comes into contact with the bottom of the preliminary seedling, and at the same time the roller is driven @
A device is known that is configured to send TLed spare seedlings to a seedling stand.

[Problem to be solved by the invention]

In the spare seedling supply device mentioned in the above reference, when taking out the remaining spare seedlings from the spare seedling holder in the placement position, the bottom of the spare seedlings gets caught in the hole in the seedling surface, so that it can be turned up. It was difficult to handle as it had to be taken out.

The present invention was devised in view of the above-mentioned circumstances, and an object of the present invention is to provide a spare seedling feeding device that can easily take out spare seedlings from a spare seedling holder in a mounting position.

[Means to solve the problem]

The characteristic configuration of the present invention is that the preliminary seedling holder is provided with a reversing roller for feeding seedlings, and is provided with a switching mechanism for switching the idling roller between an operating state and a non-operating state, so that when the preliminary seedling holder is placed in a position, The switching mechanism is configured to be in a non-active state and to be in a working state when the spare seedling holder is in an inclined position in contact with the fixing part on the machine body side, and its functions and effects are as follows. .

[For production]

In other words, according to the present invention, when the spare seedling holder is in the loading position, the idling rollers are in a non-acting state on the spare seedlings, so that the preliminary seedlings are in a stable state. . When the preliminary seedling placement tool is switched to the inclined position, the switching mechanism comes into contact with the body-side fixing part and puts the idle roller into a state in which it acts on the preliminary seedlings. By utilizing the rotation of this idle roller, the friction between the bottom of the preliminary seedling and the preliminary seedling mounting device is reduced, and the preliminary seedling is sent to the seedling platform by its own weight.

In addition, when taking out spare seedlings from the spare seedling holder that is in the loading position, the switching mechanism is brought into contact with the fixed part on the machine side, and the hand or tool is brought into contact with the switching mechanism, and the idle roller is switched to the operating state. Then remove the seedlings by pulling them out along the preliminary seedling placement tool.

〔Effect of the invention〕

Therefore, even if the spare seedling holder is in the placement position, the spare seedlings can be easily taken out using the idle rollers without getting caught in the holes of the seedling placing surface.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 6, a seedling planting device (C) is attached to the rear of the traveling body (A) via an elevating link mechanism (B) to constitute a riding type rice transplanter.
