[Detailed explanation of the invention] In this invention, a storage tank 2 is provided at the bottom of the cupboard-like box 1,
A water tank 3 is provided above the tank 2, a prey storage chamber 5 is formed by a partition wall 4 provided in the tank 3, a shallow water level retaining weir 6 is formed at the lower part of the partition wall 4, and the weir is 6
A water filter 8 is formed with micro holes 7 in the upper part of the partition wall 4, and a deep water level holding pipe 11 is removably fitted into a drain hole 10 bored in the outer water tank bottom plate 9 of the partition wall 4. Water tank 2 and the above water tank 3
Water supply pipes 13 and 14 are connected to the water supply pipes 13 and 14, and water flow control valves 15 and 16 are connected to these water supply pipes 13 and 14, respectively.
The present invention relates to a bait and insect farming device provided with. The above-mentioned cupboard-like box 1 is a foamed heat-insulating synthetic resin board 17
(Fig. 6), the overtank 2 is filled with material 18, a water storage tank 21 is provided through the water passage hole 20 at the lower end of the side plate 19, and the circulation pump 1 is connected to the tank 21.
2 and a circulating water refrigerator 22 are provided. The water tank 3 is provided in multiple stages (3 to 4 stages) as shown in FIG. 1, but it may be provided in one stage if necessary. Two bait and insect storage chambers 5 are provided on both sides by two partition walls 4, 4 which are spaced apart from each other in the center of each stage of the aquarium 3. The shallow water level holding weir 6 is provided on the bottom plate 9 in contact with the partition wall 4, but the filter 8 may be formed above the shallow water level from the lower end of the partition wall 4. The diameter of the micropores 7 of this filter 8 is set to a size that does not allow prey to pass through, but allows water and excrement to pass through. The drain hole 10 is provided between the partition walls 4, 4, and as shown in FIG. 2, a drain pipe 23 hangs downward, and a taper is formed inside the drain pipe 23 to support the deep water level holding pipe 11 at the tapered part. do. The upper end opening of this holding tube 11 is held at the height shown in FIG. The water supply pipe 14 to the water tank 3 penetrates the water tank 3 and opens above the water tank 2, and a branch pipe 24 is provided above each water tank 3, and each branch pipe 24 can also be provided with a water flow control valve 25. , each branch pipe 24 is provided with a spray hole 26. There is also a spray hole 2 in the water supply pipe 13 to the tank 2.
Drill 6. In the figure, 27 indicates the water suction pipe of the circulation pump 12, 28 indicates the freezing pipe of the refrigerator 22, and 2
Reference numeral 9 indicates a water regulating plate provided in the water storage tank 21, 30 indicates a front gap opening/closing door between the upper and lower water tanks 3, 3, 31 indicates a back plate of the cupboard-shaped box 1, and 32 indicates a side plate.

Therefore, the pump 12 and the refrigerator 22 are operated, and the water that has flowed into the water storage tank 21 from the overtank 2 is supplied into the overtank 2 and the water tank 3 through the water supply pipes 13 and 14. By adjusting the valves 15 and 16, the amount of water supplied to the water tank 3 can be reduced and the amount of water supplied to the overtank 2 can be increased. Furthermore, when the deep water level holding pipe 11 is manually separated from the drain hole 10 for 12 hours in a day, the shallow water level in the storage chamber 5 is maintained by the weir 6 as shown in the uppermost water tank 3 in FIG. It is possible to provide low tide conditions to feeding insects (such as porcupines) in the same room 5. During the other 12 hours, when the deep water level holding pipe 11 is fitted into the drainage hole 10 by hand, the water level rises to the upper end opening of the pipe 11 as shown in the second and third stage water tanks 3 in Figure 1, and the water level increases. The water is kept high (deep) and provides high tide conditions for feeding insects. This holding tube 11
You can attach and detach it 4 times every 6 hours.

Conventionally, there is a case where an overtank is installed at the bottom of a cupboard-like box or frame, and a bait and insect cultivation tank is installed above it, but water is supplied to the aquarium from a circulation pump through a water supply pipe and descends into the overtank. Furthermore, since the action of being sucked into the circulation pump was repeated, the water flowing frequently came into contact with the surface of the prey insects in the aquarium, making them unsuitable for their living conditions and easily dying, and also causing problems such as oxygen breathing and semi-hibernation due to tides. Because the habitat conditions are not suitable for insect prey, they die in a short period of time, making medium- to long-term cultivation difficult.

This proposal was made in view of the above defects, and
Since the present invention is configured as described above, by adjusting the water volume control valves 15 and 16, the amount of water supplied to the water tank 3 can be reduced and the amount of water supplied to the overtank 2 can be adjusted to be increased, thereby improving overefficiency. At the same time, the frequency of running water (the number of water circulations) that comes into contact with the insect prey in the aquarium 3 can be reduced, and shallow and deep water levels can be alternately realized several times a day, providing natural habitat conditions of low tide and high tide. It is suitable for medium- to long-term cultivation of insect prey.
