Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a fully automatic constant-quantity water supply device that supplies water at regular intervals.

[0002]

[Prior art]

 For example, in the cultivation of plants that require a large amount of water, such as sprouts, it is necessary to supply water continuously at regular intervals, since failure to supply water causes damage to plant growth.

However, since the conventional water supply device is generally carried by human power, it takes time and effort to supply water, and the efficiency is extremely low. Loss of water supply to plants can have a significant impact on growth and severely reduce commercial value.

【Example】

 Next, a fully automatic quantitative water supply device 1 according to the present invention will be described based on an embodiment shown in the drawings. FIG. 1 shows a case in which the fully automatic constant-quantity water supply apparatus 1 is applied to a sprouts 30. For convenience, portions having the same function are denoted by the same reference numerals, and description thereof is omitted. First, there is a tank 3, an opening is provided in the bottom surface 3 a of the tank 3, and a valve holder 5 is provided in the opening. The valve holder 5 has an outlet 6 at the bottom 5b and an upper portion 5a protruding from the inner surface of the tank 3 to accommodate a valve body 7 made of a ball. The valve body 7 is connected to the float 9 by a connecting rod 8. The float 9 can be raised and lowered by the amount of water in the tank 3, and the valve body 7 can be raised and lowered by raising and lowering the float 9 to open and close the outlet 6. By appropriately adjusting the length of the connecting rod 8, it is possible to adjust the opening state of the outlet 6 at a desired time. On the other hand, a spring 11 urged upward is attached to the bottom 5b of the valve holder 5. The spring 11 supports the self-weight of the valve element 7 when the water surface descends for a certain period of time, thereby increasing the dimensional accuracy of the connecting rod 8. 13 is a divergent watering can attached to the bottom 5b.

A water supply unit 15 is provided above the tank 3. The water supply unit 15 includes a nozzle 19 connected to the water pipe 17 and a cock 21 that is adjustably screwed to the nozzle 19 to adjust the amount of water. Reference numeral 23 denotes a knob of the cock 21, reference numeral 25 denotes a cap of the nozzle 19, and reference numeral 27 denotes packing. A scale (shown in FIG. 3B) is provided on the upper surface of the cap 25, and a time is set by adjusting a mark 23a provided on a knob 23 of the cock 21 in accordance with the scale to adjust a water supply amount.

The opening areas of the outlet 6 and the watering can 13 are larger than the amount of water supplied from the water supply unit 15.

The bean sprouts cultivator 30 is formed by stacking upper and lower two-tiered containers 31 and 32 containing bean sprouts 35 in an outer container 33. The outer container 33 has a large number of holes 34 on the bottom surface.

In the above configuration, water for water supply is continuously supplied from the water supply section 15 into the tank 3 via the water pipe 17. The amount of water supply is set in advance according to the degree of opening of the cock 21. When the water surface is initially low, the valve element 7 closes the outlet 6 as shown by the solid line in FIG. When the water in the tank 3 accumulates in this state, the float 9 floats upward as shown by a dashed line in FIG. As a result, the valve element 7 connected to the float 9 also moves upward, so that the outlet 6 is opened. Therefore, the water 27 in the tank 3 is sprayed from the outlet 6 through the watering can 13.

On the other hand, when the watering from the watering can 13, that is, the water supply to the seeds 35 of the sprouts proceeds, the float 9 tends to gradually move downward. However, since a spring 11 urged upward is attached to the bottom 5b of the valve holder 5, the self-weight of the valve body 7 when the water surface descends is supported by the spring 11 for a certain period of time. Prevent 7's descent. Therefore, the opening state of the outlet 6 is maintained for a predetermined time, and water supply to the seeds 35 of the sprouts is ensured for a predetermined time.

When the water supply proceeds in this way and the water level drops so that the support of the valve element 7 by the force of the spring 11 cannot withstand, the float 9 moves downward as shown by the solid line in FIG. As a result, the valve element 7 also moves downward, and eventually closes the outlet portion 6.

By repeating such an operation, water supply from the outlet 6 and the watering can 13 is performed continuously and fully automatically at regular intervals. Therefore, water supply to plants can be efficiently performed over a long period of time, and labor can be saved. Therefore, it is convenient for use in dry land.

The present invention is not limited to the above embodiment. For example, the plant to be cultivated is not limited to bean sprouts, but may be other vegetables or bonsai. If the dimensional accuracy of the connecting rod 8 corresponds to the amount of water supplied at regular intervals, the installation of the spring 11 is unnecessary. The shape of the valve element 7 is arbitrary as long as it can move in conjunction with the float 9.

Further, as shown in FIG. 4, a hose 29 can be connected to the outlet 6. In this case, if a plurality of hoses 29 are provided in series, water can be supplied to a plurality of plant cultivation facilities 40, which contributes to an increase in scale.
