Fig. 4 is a partial cross-sectional view before water is poured into the water storage bag, and Fig. 5 is a partial cross-sectional view showing water being poured into the water storage bag. It is a later partial sectional view. A detailed explanation will be given below based on the drawings.

[0011] The automatic irrigation device according to this invention consists of a hollow pillar 1 installed upright on the ground 10. 2, a water tank 18 for the plants 16 provided on the upper part 14 of the column 12, and the inside 2 of the column 12. 0 and which generates water pressure that pushes water 22 up into the water tank 18 by contraction force. A flexible water storage bag 24, a water pipe 26 that communicates the water tank 18 and the water storage bag 24, and a water supply A constant water level valve 28 is provided in the tank 18 and controls the water flow in the water pipe 26. The main structure is Moreover, as shown in FIGS. 4 and 5, when the water storage bag 24 is expanded, It may also be configured to include an inscribed bag-like body 30.

0012 The pillar 12 can be composed of a hollow cylindrical metal tube with a height of approximately 4 m or more, and the top is Thin and thicker at the bottom. The water conduit 26 is in the thin part at the top, and the water pipe 26 is in the thick part at the bottom. A water bag 24 is accommodated. Note that the pillar 12 is installed upright on the ground. However, the term ``upright'' here includes cases where it is erected diagonally.

[0013] The plant 16 is a flower or the like planted in a pot 48, and is immersed in the water tank 18 together with the pot 48. has been done. There is a hole (not shown) in the bottom of the pot 48, so that a certain amount of water can be poured into the water tank 18. 22, water 22 will be sucked up from this hole.

[0014] The constant water level valve 28 can be configured by a ball tap valve. In other words, 50 floats and 50 floats. A rotating rod 52 fixed to the shaft 50 and a support portion to which the rotating rod 52 is rotatably attached. The rotating rod 5 is inserted into or removed from the water outlet 56 of the water conduit 26. 2 and a stopper 58 provided at the end. The float 50 corresponds to the water level in the water tank 18. It moves up and down. When the water level in the water tank 18 is sufficient, the buoyancy of the float 50 closes the stopper. 58 fits into the water outlet 56 to stop the flow of water 22 from the water pipe 26 to the water tank 18. make it stop If the water level in the water tank 18 is insufficient, the weight of the float 50 will cause the rotation The movable rod 52 rotates around the support member 54, and the stopper 58 is removed from the water outlet 56. In this way, water 22 is supplied from the water pipe 26 to the water tank 18.

[0015] The water storage bag 24 is made of an elastic rubber-like material, and has a water inlet hole 60 and a water outlet. It has a hole 62. The water inlet hole 60 and the water outlet hole 62 are connected to the water inlet pipe 64 and the water outlet hole 62, respectively. It is fixed to the water pipe 26 with fasteners 66 and 68. The water injection pipe 64 is connected to the outside of the pillar 12. It has a water inlet 70 and a manual operation valve 72.

[0016] The bag-like body 30 is attached to the inside 20 of the column 12 so as to cover the water storage bag 24. . Furthermore, the bag-like body 30 may have no bottom or be elastic, and may be made of cloth, net, string, etc. is formed.

[0017] Next, the operation of the automatic irrigation device according to this invention will be explained.

[0018] First, as shown in FIG. 2, when the water 22 in the water storage bag 24 is empty or low, The manual operation valve 72 is opened and water is injected from the water inlet into the water storage bag 24 by applying pressure. this pressure The force needs to be greater than the contraction force of the water storage bag 24. Please note that water is injected under pressure. To do this, use water pressure from the tap, water pressure from a pump, the weight of water from a high place, etc. do it.

[0019] In this way, when water is injected against the contraction force of the water storage bag 24, as shown in FIG. The water storage bag 24 expands. When the water storage bag 24 is full, close the manual operation valve 72 and Finish the water. At this time, the water pressure inside the water conduit 26 is reduced by the contraction force of the water storage bag 24. The value becomes sufficient to push water up to the water tank 18, and it passes from the water storage bag 24 to the water conduit 26. water is supplied to the water tank 18. When the water level in the water tank 18 becomes constant, the constant water level valve 2 8 operates to stop the water 22 in the water conduit 26. Additionally, the water level in the water tank 18 decreases. Then, the constant water level valve 28 operates to cause water 22 to flow from the water pipe 26. This repetition will save This continues until the water bag 24 is completely deflated. Therefore, the number of times of irrigation can be greatly reduced.

[0020] Furthermore, as shown in FIGS. 4 and 5, when the water storage bag 24 expands due to water injection, Since it is inscribed in the bag-like body 30, it expands along the shape of the bag-like body 30. In other words, bag-shaped By shaping the body 30 into a desired shape, the water storage bag 24 when inflated can be shaped into a desired shape. I can do it. In particular, if the water storage bag 24 partially expands abnormally, The expanded portion is pressed when it first comes into contact with the bag-shaped body 30, causing abnormal expansion. can be suppressed.

[0021] Next, this embodiment will be described with specific numerical values.

[0022] Two rubber sheets with a thickness of 0.4 mm are stacked to form a bottomed circle with a diameter of 5 cm and a length of 60 cm. Water is poured into the cylindrical water storage bag 24 by applying pressure against the contraction force of the water storage bag 24. Then, it can be expanded to a size of 20 cm in diameter and 100 cm in length. this In this case, it can store 31.4 liters of water. In addition, water storage bag 24 will shrink until the remaining water volume is about 3 liters, so the amount of water pushed up to the water tank 18 will be is approximately 28.4 liters.

[0023] In addition, for the water storage bag 24 of the above dimensions, a diameter 20cm made of canvas fabric is used. A bottomed cylindrical bag-like body 30 having a length of 100 cm and a length of 100 cm can be provided.

[0024] FIG. 6 shows a water storage bag in still another embodiment of the automatic irrigation device according to this invention. It is a partial sectional view after water injection. The same parts as in Fig. 5 are given the same reference numerals and explanations are omitted. .

[0025] A water injection pipe 80 is connected to the water supply pipe 26 in a branched manner. In this way, the water storage bag 24 Since there is no need to provide the water injection hole 60 in FIG. 5, the structure becomes simpler. Also note A check valve 82 is inserted into the water pipe 80. Therefore, the water 22 flows inside the water injection pipe 80. Since water flows only in the injection direction and not in the opposite direction, there is a manually operated valve 72 shown in Fig. 5. It is easier to operate than before. In addition, in this embodiment, the bag-like body 30 is provided. However, the bag-like body 30 may be omitted.

[0026]

[Effect of the idea]

According to the automatic irrigation device according to this invention, the contraction force of the water storage bag is used to plant the plants at the top of the column. Water can be pushed up to the water tank for objects, so once you pour water into the water storage bag, water will be supplied. Irrigation can be performed automatically using simple equipment using a constant water level valve in the tank without requiring any power source. I can do it.

[0027] In addition, by providing a bag-like body that is inscribed when the water storage bag expands, when the water storage bag expands, The shape of the water storage bag can be made to match the shape of the bag, and abnormal local expansion of the water storage bag can be suppressed. I can do that.
