Description

[Detailed description of the invention] [Industrial field of application] The invention consists of a seedling tray that can be moved back and forth in the horizontal direction, and a seedling vertical feeder that forcibly feeds the placed seedlings toward the seedling take-out port. The present invention relates to a seedling planting device of a rice transplanter, which is provided in a protruding position on the side of a seedling placement surface.

[Conventional technology]

In this type of seedling planting device, the vertical seedling feeder always protrudes from the seedling placement surface of the seedling stand, and has a braking action to prevent the placed seedlings from slipping off. Therefore, when replenishing seedlings, it is inevitable that the front end of the seedlings being replenished from the upper position of the seedling stand will get caught on the vertical seedling feeder and stop once. Currently, the front end of the supplied seedlings is lifted by hand and guided to move toward the seedling removal port.

Therefore, conventionally, as shown in Japanese Utility Model Application Publication No. 57-11919, the bottom plate of the seedling stand was moved to the upper part of an endless rotating belt-like body that was used as a vertical seedling feeder to transport the seedlings supplied from the upper part of the seedling stand. The front end of the supplied seedlings is configured to be switchable between a first state in which the seedlings are guided to the seedling take-out port side through the feeder, and a second state in which the endless rotating band serving as the vertical seedling feeder allows the vertically feeding action of the supplied seedlings. It was designed so that it could be refilled without having to lift it by hand.

[The problem that the idea aims to solve]

Switching of the bottom plate as a seedling feeding guide is done by parallel movement, so when feeding seedlings, the bottom plate, which is in the second state that allows vertical feeding of the seedlings, is used as a seedling vertical feeder to feed the seedlings fed from the top of the seedling stand. After replenishing the seedlings, the bottom plate in the first state is transferred to the first state in which the bottom plate is guided through the upper part of the endless rotary belt as a seedling feeder to the seedling outlet side. Separately from seedling replenishment, it was necessary to perform a switching operation to the second state that allows the vertical feeding action of the seedlings.

The present invention aims to speed up the supply of seedlings by devising the switching structure of the seedling supply guide.

[Means to solve the problem]

The characteristic configuration of this invention to achieve the above purpose is as follows:
A seedling tray that can be moved back and forth in the horizontal direction is provided with a vertical seedling feeder that forcibly feeds the placed seedlings toward the seedling take-out port so as to protrude from the seedling loading surface at all times, and , a first state in which the seedlings supplied from the upper position of the seedling tray are moved and guided through the upper part of the vertical seedling feeder toward the seedling take-out port side, and a second state in which the vertical feeder is allowed to vertically feed the supplied seedlings. In the seedling planting device of a rice transplanter, the seedling supply guide is provided with a seedling supply guide whose posture can be freely changed. The present invention is constructed in such a manner that it is provided with a part for placing supplementary seedlings on the upper side of the swing fulcrum, and this structure provides the following functions and effects.

[Effect]

When seedlings are placed on the upper side of the seedling supply guide, the lower side of the seedling supply guide seesaws and moves away from the seedling placement surface, allowing the seedlings supplied from the top of the seedling tray to pass through the top of the vertical seedling feeder. It is switched to the first state in which the movement is guided toward the extraction port side. Then, by seesawing the seedling supply guide due to the load of the supplied seedlings or by manually swinging the seedling supply guide, the system is switched to the second embodiment which allows the vertical feeding of the supplied seedlings by the vertical seedling feeder.

[Effect of idea]

As a result of the above configuration, the seedling replenishment guide can be switched between the first state and the second state while replenishing the seedlings, thereby speeding up the supply of replenishing seedlings.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

The seedling planting device of the riding type rice transplanter shown in Figs. 1 to 4 is constructed.
This is a transmission case that is driven from the transmission case 1 through a transmission shaft 2, and a planting case 3 extends rearward from the transmission case 1, and planting claws 4 are provided on both left and right sides of the rear part of the transmission case 1, respectively. A seedling planting mechanism 5 is provided which causes a forced circulation movement.

6 is a seedling stand that can be moved back and forth in the lateral direction along a sliding rail 7 attached to the upper part of the planting case 3; 8 is a support frame extending upward from the transmission case 1; This support frame 8
The upper end part fits into a U-shaped rail 9 provided at the upper part of the back surface of the seedling stand 6, and the seedling stand 6
A guide roller 10 is provided to guide the reciprocating movement.

Reference numeral 11 denotes a rotary star wheel-shaped seedling vertical feeder that protrudes toward the seedling placement surface through a notch 6b formed in the bottom plate 6a of the seedling platform 6, and is used to guide the reciprocating path of the seedling platform 6. The seedlings placed on the seedling stand 6 are sent to the side of the seedling take-out port 12 formed in the slide rail 7 by being driven and rotated in one direction at a fixed amount in conjunction with the movement to the end of the slide rail 7. ing.

Reference numeral 13 denotes a seedling supply guide, which includes a seedling supply plate 13a that is swingable on the upper side of the side frame 6c of the seedling table 6 and serves as a part for placing supplied seedlings around a horizontal axis P serving as a fulcrum. A lattice-shaped guide frame 13b using a rod-like member extending to the vicinity of the seedling take-out port 12 is attached to the seedling supply plate 13a, and a lattice-shaped guide frame 13b is attached to the bottom plate 6a of the seedling stand 6. A lattice-shaped groove 13c is recessed in which the seedlings can be stored flush or almost flush, and the seedling supply plate 13a and the lattice-shaped guide frame 13b are integrally swung around the horizontal axis P. , the first part moves and guides the seedlings supplied from the upper part of the seedling table 6 through the upper part of the vertical seedling feeder 11 to the side of the seedling take-out port 12.
and a second state in which the lattice-shaped guide frame 13b is fitted into the lattice-shaped groove 13c of the seedling table 6 to allow the vertical feeding of supplied seedlings by the vertical seedling feeder 11. .

When replenishing seedlings, by setting the seedling supply guide 13 provided on the seedling tray 6 to the first state, the seedlings are simply fed from the top of the seedling tray 6, and the seedlings are fed along the seedling supply guide 13. While sliding, the seedlings can be smoothly fed and guided to the side of the seedling take-out port 12 through the upper part of the vertical seedling feeder 11. However, when planting after replenishing seedlings, the seedling replenishment guide 13
By switching to the second state in which the seedlings are accommodated in the lattice grooves 13c, the supplied seedlings can be reliably sent to the side of the seedling take-out port 12 using the vertical seedling feeder 11.

Next, another example will be described.
