Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to an LM device used to supply air, ship cranes, etc. to aquaculture ponds for cultivating crayfish, fish, and the like. (Conventional technology) Aquaculture has become more and more popular in recent years, but if we take crayfish as an example, the time when crayfish consume oxygen is concentrated between 9pm and 6am. During this time, the crayfish tend to suffer from a lack of oxygen, which causes stress on the crayfish, making them less likely to feed and causing poor growth. This tendency was especially noticeable during low temperatures in winter. Therefore? Using JI number of barges, air supply devices such as blowers are installed on these to supply air to the aquaculture pond, or water from the aquaculture pond is sprayed using a submersible pump installed on the barge. Alternatively, it has conventionally been possible to supply air by installing an air pipe at the bottom of the aquaculture pond. (Policy B to be solved by the invention) In the conventional example, the barge is moored at a fixed position, so multiple barges are required to supply the necessary amount of air to the aquaculture pond. Also, the fuel consumption for the air supply system was considerably wasted. This problem has also been common in the case of spraying water.In addition, equipment for piping air pipes to the bottom of aquaculture ponds is expensive and poses a problem in terms of profitability. It was made to solve the
The purpose is to provide an aquaculture device that is inexpensive and can uniformly supply air and feed. (Means for Solving the Problem) The present invention aims to achieve the above object. A movable floating body is provided in a water reservoir for breeding, and the floating body has a first nozzle whose opening is located below the water surface, and a suction body that is located inside the first nozzle and uses negative pressure generated inside the first nozzle. A second nozzle to which a force is applied, a pressure-feeding means for force-feeding a liquid to the first nozzle, and a feeding section connected to the second nozzle via a ship conduit are provided. As mentioned above, since the floating body is movable, uniform air supply and feeding can be achieved by making the floating body draw an appropriate trajectory. Also, since it uses the Venturi effect to supply air and feed,
A sufficient air supply effect can be obtained with a small drive source. Moreover, if a third nozzle is provided and air is pumped to this as in claim (2), the Venturi effect becomes even more effective. Furthermore, as in claim (3), air can be supplied by rotating the floating body! 8 Bait: = Can be done more uniformly. (Effects of the Invention) As described above, since air supply and feeding are performed uniformly, one barge is sufficient, and therefore it is advantageous in terms of cost. Also, since it uses the Venturi effect to supply air and feed,
This will help reduce fuel consumption. (English Example) The following example will be explained based on the drawings. Figures 6 and 7
As shown in the figure, 100 is a barge, and a supply vibrator 1o1, a first connecting tube 102, and a second connecting tube 103 are attached to the rear end of one #9100, and the supply vibe 101 has a plurality of The first nozzles 104 are connected at an arbitrary interval in the lateral direction, and the primary connecting pipe 102 and the secondary connecting pipe 1
03 are connected to the same number of first nozzles 104 and the same number of air supply vibrators 11) 5 and feeding vibrators (second nozzles) 1o6. A third nozzle 107 is connected to the tip of the first nozzle 104 and to the outside thereof.
The tip of an air supply vibrator 05 is connected to the side surface of the nozzle 104, and the tip of a wire pipe 106 penetrates the side wall of the first nozzle 104 to reach the tip of the same nozzle 104. As shown in FIG. 8, the supply vibration] 01 is the link mechanism 10
It is attached to the barge 100 via 8. This link mechanism 108 allows the angle of inclination of the first nozzle 104 to be changed, and by appropriately setting this angle, bubbles can be injected toward the bottom of the aquaculture pond. Returning to FIGS. 6 and 7, 109 is a pump, 11
0 is the blower, 111 is the morph, and the pump 1098 and blower 110 are the morph 111! ! jA is designed to be moved. The blower 110
It is connected to the next connecting pipe 102. Further, the pump 109 is connected to a nl suction hood 114 via a discharge vibrator 113. As shown in FIG. 9, a hopper 115 is attached to the suction hood 114. This hopper 115 (
It is also used to supply crushed feed into the hood 114. The pump 109 is located inside the suction hood 114! In order to suck water from the breeding pond, feed will be mixed with the water in the same hood 14. This F4 mixed liquid (plate-like material) is further sucked by the pump 109 and sent to the secondary connecting pipe 103 via the discharge pipe 113 and the discharge pipe 113a. A feeding section is provided in which food is supplied. As shown in FIG. 10, this feeding section 116 includes an input hopper 117 having a bottom formed by an inclined surface, a partition wall 118 arranged at an arbitrary distance from the bottom of the hopper 117 and extending upward, and a partition wall 118 extending upward. The hopper 117 is provided in the hopper 118 so as to be movable up and down.
It consists of an elevating plate 119 that sets the distance between the bottom part of the partition wall 118 and the partition wall 118 to an arbitrary length. [-1 charged into the hopper 117 is determined by the vertical position of the elevating plate 119
8 is determined. The bottom of this hopper 117 is provided with one end of a suction pipe 120 facing thereto. The other end of the suction pipe 120 is connected to the secondary connecting pipe 103. When the pump 109 is operated in the above configuration, water from the aquaculture pond sucked through the suction hood 114 is sent to the first nozzle 104 via the discharge pipe 113, the discharge pipe] 13a8, and the supply pipe 101, Negative pressure is generated at the tip of the first nozzle 104. As a result, a suction force is generated in the candy vibrator 106, and the lees is passed through the secondary connecting pipe 103 and the suction pipe 120! The fill in part 116 is aspirated. If it is necessary to further increase this suction force, the blower 110 is operated. This is because negative pressure is generated between the first nozzle 104 and the second nozzle 107 because air is force-fed to the air-feeding vibrator 105 by the operation of the blower 110. A suction force acts on the first nozzle 104, and this suction force further increases the suction force against the feeding vibrator 106. In this way, the liquid material, pelleted feed, and air are ejected from the third nozzle 107 into the aquaculture pond. Next, the means for turning the barge 1004 will be described. In FIG. 1, reference numeral 2 denotes a support column, which is fixed to a support tube 3 attached to a fixed pile 4 with a beam 5. 9 is pillar 2
