Description

[Detailed explanation of the idea] The present invention relates to a seedling supply warning device for a rice transplanter.

That is, a seedling feeder that engages with the bed soil of the mat seedlings is installed near the bottom of the seedling stand that extends from the guide rail where the tips of the mat seedlings collide and the planting claws are exposed. In a rice transplanter, an alarm device is activated when the bed soil part separates from the seedling feeder and it is necessary to supply seedlings when there are few remaining seedlings, which requires special installation of sensors and complicated wiring structure as in the past. The present invention is designed to have a simple structure, to operate reliably, and to be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the rice transplanter. Swing cases 6 and 6 each having wheels 5 and 5 mounted on the rear sides of the engine E installed above the front of the long float 12 are installed at the rear of the machine. handle rod 8 upward from the rear of the planting case 7,
8 is extended, and at the front lower part of the handle rods 8, 8,
The guide rail 2 installed horizontally has a notch 9.9 through which both planting claws 1, 1 can be seen, so that the lower part of the seedling stand B, which is reciprocally movable and installed diagonally, can be seen onto the guide rail 2. , a plurality of narrow grooves 11 are formed at intervals in the horizontal direction at positions a little apart above the lower ends of both the image mounting surfaces 10, 10 of the seedling mounting table B, and a shaft is provided below so as to rotate intermittently. The upper part of each suspended star foil 3 is installed so as to slightly protrude upward through the narrow groove 11, and is constructed in the same manner as the conventional structure.

A shows a conventional mat seedling, and the bed soil part a of the mat seedling A has electrical conductivity.

Further, as schematically shown in FIG. 3, the guide rail 2 and star foil 3 are connected to both ends of an electric circuit C to which a battery 13 is connected, and an alarm lamp is connected to the electric circuit C. 4 is installed on a support 14 attached to the handle bar 8a on the handle rod 8, 8 side, and both alarm lamps 4, 4 are installed so as to be connected to both the screen mounting surfaces 10, 10 side, respectively. Configure.

Note that in addition to the star foil, a rack or the like may be used as a seedling feeder, and in addition to the alarm lamp, for example, a buzzer or the like may also be used as an alarm device.

Furthermore, a plurality of star foils 3 are provided in the vertical direction of the defining surfaces 10, 10 (7), and the star foils 3, guide rails 2,
It is also possible to connect the circuits each consisting of the alarm lamps 4 in parallel so that the lamps 4 are turned off one by one as the number of mat seedlings A decreases.

Therefore, during the rice planting work, the planting claws 1, 1 are placed on one block of the mat seedlings A with the mat seedlings A, A placed on the screen surfaces 10, 10 and their tips abutting against the guide rail 2. The mat seedlings A are scraped off and planted on the rice field surface, and each star foil 3 that rotates intermittently engages with the lower surface of the bed soil part a to intermittently send the mat seedlings A to the guide rail 2 side, as shown in Fig. 4. To,
When the star foil 3 is engaged with the bed soil part a and the mat seedlings A do not need to be replenished yet, the star foil 3 and the guide rail 2 are energized via the bed soil part a, and the alarm lamp 4 is turned on. Light.

When there are few remaining mat seedlings A and it is necessary to replenish them, the rear part of the bed soil part a separates from the star foil 3, as shown in Fig. 5, and the current circuit is cut off. The warning lamp 4 goes out, and the operator sees this and knows that the mat seedlings A must be replenished.

In this way, the present invention has a seedling feeder that engages with the bed soil of the mat seedlings near the bottom of the seedling platform that extends from the guide rail where the tips of the mat seedlings collide and the planting claws are exposed. In the rice transplanter configured by installing an electric circuit, an electric circuit is connected to the guide rail and the seedling feeder, which can be energized through the soil bed, and an alarm device is interposed in the electric circuit. When it is necessary to supply seedlings when the bed soil is separated from the feeder and there are few remaining, the electricity can be cut off and an alarm can be issued.The structure is simple, without the need for special installation of sensors or complicated wiring structure as in the past. It has the feature that it can be operated reliably and suitably.
