Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a water sprinkling prevention structure for a watering machine of a seedling-raising seeding device.

(Prior Art) A seedling-raising seeding device is conventionally well known, in which a seedling-raising box is sequentially transferred in one direction to a soil-filling machine, a watering machine, and a seeding machine using a transfer mechanism, thereby continuously supplying bed soil, watering, and sowing.

The irrigation machine of such a seeding device for raising seedlings is equipped with an irrigation pipe that sprays water from above into the nursery box. A pair of guide plates was installed in order to prevent the seedling box and peripheral equipment from getting wet by watering outside the area.
- Shown in Publication No. 114614. In this case, to completely prevent water sprinkling, a pair of water sprinkling prevention guide plates are installed.
It is arranged on the inner side of the peripheral wall of the seedling raising box and extends below the lower end of the peripheral wall of the seedling raising box. Since the peripheral wall of the seedling box comes into contact with the guide plate when the seedling box is transferred, the guide plate is supported via the irrigation machine frame so as to be swingable in the direction of transfer of the seedling box. Thereby, the peripheral wall of the seedling growing box pushes and swings the guide plate during transfer, so that the guide plate can climb over the peripheral wall.

(Problems to be Solved by the Invention) The seedling-raising seeding device disclosed in the above-mentioned publication transports the seedling-raising boxes in only one direction. Therefore, although supplying bed soil to the seedling nursery boxes using a soil-filling machine, watering using a watering machine, and sowing seeds using a seeding machine can be carried out continuously, supplying soil to the seedling nursery boxes with covering soil must be performed in a separate process. Therefore, the guide plate of the irrigation machine can also swing in the transfer direction by being pushed by the surrounding wall of the seedling box, but it is not allowed to swing in the anti-transfer direction by providing a stopper.

Furthermore, in the system disclosed in the above-mentioned publication, the guide plate is supported via the irrigation machine frame. In this case, since the guide plate needs to be swingable, it is not supported directly on the irrigation machine frame, but rather on a support shaft protruding from the irrigation machine frame and supported by this support shaft. Therefore, a separate support shaft is required, which increases the number of parts and the number of assembly steps.

In view of the above, the present invention is based on soil supply, irrigation, seeding,
The present invention provides a sprinkler prevention structure for a watering machine that is applied to a seedling seeding device that can continuously supply covering soil, and further reduces the number of parts and assembly man-hours compared to conventional systems.

(Means for Solving the Problems) The features of the present invention in order to solve the problems of the prior art include a transfer mechanism 3 for reciprocating the seedling nursery box 2, and a transfer mechanism 3 for reciprocating the seedling nursery box 2; A soil-entering machine 6 that sometimes supplies bed soil and also supplies cover soil when returning, an irrigation machine 7 having an irrigation pipe 41 that sprays water from above into the seedling-raising box 2, and the seedling-raising box 2.
A pair of guide plates 65 are provided to prevent the irrigation pipe 41 from sprinkling water to the outside of the irrigation area D.
In the seedling-raising seeding device 1 which is disposed inwardly from the peripheral wall of the seedling-raising box 2 and extends downward from the upper end of the peripheral wall of the seedling-raising box 2, the guide plate 65 moves reciprocally toward the surrounding wall of the seedling-growing box 2. The seedling box is fitted and supported by the irrigation pipe 41 so as to be able to swing freely in the reciprocating direction of the seedling box so that the seedling box can be moved over the peripheral wall when pushed by the user.

(Function) By being reciprocated by the seedling raising transfer mechanism 3, the seedling raising box 2 can receive bedding soil supply and covering soil supply by the soil insertion machine 6 in one step. Both when the seedling raising box 2 moves forward and backward, the guide plate 65 is pushed by the surrounding wall of the seedling growing box and swings, thereby being able to climb over the surrounding wall.

The guide plate 65 is fitted into the irrigation pipe 41 and supported in a swingable manner, thereby eliminating the need for a separate support member.
