Description

Technical Field

[0001] The utility model relates to the technical field of aquatic product breeding, in particular to a bait feeding device for deep-water cage breeding. Background Art

[0002] Cage culture is a common practice in aquaculture. The cage limits the range of movement of the cultured animals to provide them with a natural breeding environment. In order to increase production, artificial bait needs to be added while breeding in the natural environment. Since cage culture requires multiple feedings, automatic feeding devices are generally used to improve feeding efficiency. However, the water vapor evaporating from the water surface will corrode the traditional feeding device and cause the bait inside to deteriorate. Therefore, a feeding device that isolates water vapor is needed to extend the shelf life of the bait.

[0003] Chinese patent CN218184732U discloses a deep-water cage bait feeding device, comprising a box body, an annular cavity formed on the inner wall of the box body, a cavity formed at the center above the inner wall of the box body, an air inlet slot formed on the upper side of the right surface of the box body, a feeding port formed on the left side of the upper surface of the box body, a discharge trough formed on the lower side of the right surface of the box body, a conical feed port formed on the left side above the inner wall of the discharge trough, a motor slot formed on the lower side of the inner wall of the discharge trough, and a stirring mechanism provided on the inner wall of the cavity. The utility model can cool or dry the internal bait in hot weather or when the internal bait is easily damp, thereby ensuring the quality of the bait and preventing the problem that feeding deteriorated bait to aquatic products will affect the healthy growth of aquatic products, avoid causing a large number of aquatic product deaths, and avoid serious economic losses.

[0004] There are several points for improvement in the above scheme: single-stage feeding will cause water vapor to erode into the interior of the box along the feeding path; it takes a long time for the bait to spontaneously enter the deep water by gravity. Utility Model Content

[0024] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figures 1 to 6As shown, a bait feeding device for deep-water cage aquaculture includes a storage box 1 for isolating water vapor, a feeding pipe 5 for sealed feeding, and a conveying pipe 6 for feeding to the bottom of the water. The storage box 1 includes an isolation box 2 for preliminarily isolating water vapor, a switch shaft 3 as a feeding switch, and a downpipe 4 for secondary isolation of water vapor. The storage box 1 is set on the ground, the conveying pipe 6 is installed on the side of the storage box 1 and its lower half is immersed in water, the isolation box 2 is installed at the inner center of the storage box 1, the downpipe 4 is installed directly below the storage box 1 and is connected to the bottom of the isolation box 2, the switch shaft 3 is vertically inserted into the downpipe 4, the feed pipe 5 is connected to the downpipe 4 at an inclined angle, and the feed pipe 5 is also connected to the conveying pipe 6.

[0026] The feeding device first puts the bait into the storage box 1 and stores it, and then passes through multiple isolations of the isolation box 2, the discharge pipe 4 and the delivery pipe 6, which prevents the water vapor evaporated on the water surface from entering the storage box 1 along the delivery path when feeding the bait, causing the remaining bait to mold and deteriorate. At the same time, the bait is quickly sent into the deep underwater through the delivery pipe 5, which solves the problem of slow sinking speed of the bait during free feeding. The switch shaft 3 serves as a feeding switch to control the diversion of the isolation box 2. When the switch shaft 3 is rotated, the isolation box 2 first performs a preliminary diversion on the bait in the storage box 1 and stores part of the bait inside itself. When the switch shaft 3 is rotated again, the bait in the isolation box 2 enters the discharge pipe 4, is discharged into the delivery pipe 6 through the feed pipe 5 after uniform discharge, and is finally discharged directly into the bottom of the water through the delivery pipe 6.

[0027] See also Figures 1 to 4 As shown, the isolation box 2 is provided with a column 21, a baffle 22, a slide 23 and a bottom plate 24. The column 21 is installed at the inner center of the isolation box 2, the baffle 22 is rotatably installed on the column 21 and fits against the inner wall of the isolation box 2, the slide 23 is annularly arranged on the outer surface of the isolation box 2, and the bottom plate 24 is installed at the bottom of the isolation box 2.

[0028] The column 21 serves as the rotation center of the baffle 22. The size of the baffle 22 corresponds to the size of the chute 23. The bottom plate 24 is used to connect the discharge pipe 4. When the switch shaft 3 rotates, the baffle 22 rotates around the column 21 and opens the chute 23. The bait in the storage box 1 enters the isolation box 2 through the chute 23, and then the baffle 22 closes the chute 23 to complete the initial diversion.

[0029] See also Figure 4 As shown, a closing plate 211, a spring 212, a gasket 213 and a first bevel gear 214 are provided on the column 21. The closing plate 211 is slidably installed on the column 21, the first bevel gear 214 is installed at the bottom of the column 21, the spring 212 is arranged between the first bevel gear 214 and the closing plate 211, and the gasket 213 is arranged on the lower surface of the closing plate 211.

[0030] The sealing plate 211 and the bottom plate 24 are sealed to the bottom of the isolation box 2 to form a closed space inside. The spring 212 is used to control the reset of the sealing plate 211. When the switch shaft 3 rotates, the sealing plate 211 is lifted up, and the bait in the isolation box 2 enters the discharge pipe 4. The first bevel gear 214 is controlled by the switch shaft 3 to drive the baffle 22 to rotate.

[0031] See also Figures 1 to 5 As shown, a knob 31, a cam 32 and a second bevel gear 33 are provided on the switch shaft 3. The knob 31 is mounted on one end of the switch shaft 3. The cam 32 is fixedly mounted on the switch shaft 3 and is located in the discharge tube 4. The second bevel gear 33 is fixedly mounted on the switch shaft 3 and is located in the discharge tube 4.

[0032] The knob 31 is used to facilitate manual rotation of the switch shaft 3. As the switch shaft 3 rotates, the cam 32 hits the sealing plate 211 to lift it up, thereby discharging the bait in the isolation box 2. The second bevel gear 33 and the first bevel gear 214 engage with each other to ensure that the switch shaft 3 can drive the rotation of the baffle 22 on the isolation box 2.

[0033] See also Figures 3 to 5 As shown, the discharge pipe 4 is provided with a bracket 41, a nozzle 42, an air hole 43 and a third bevel gear 44. The bracket 41 is installed on the top of the discharge pipe 4, the third bevel gear 44 is installed on the upper surface of the bracket 41, the air hole 43 is arranged on the outer surface of the discharge pipe 4, and the nozzle 42 is installed at the bottom of the discharge pipe 4 and is connected to the feeding pipe 5.

[0034] The third bevel gear 44 is driven by the meshing of the second bevel gear 33 to drive the entire discharge pipe 4 to rotate. The bracket 41 provides installation positioning for the third bevel gear 44. The air hole 43 is used to balance the internal and external air pressure in the discharge pipe 4 to avoid blockage. The nozzle 42 is connected to the feeding pipe 5 to facilitate the provision of falling acceleration for the bait to avoid accumulation in the feeding pipe 5.

[0035] See also Figure 1 and Figure 2 As shown, the feed pipe 5 is provided with a rotating shaft 51, a rotating frame 52 and an inlet 53. The rotating shaft 51 is installed at one end of the feed pipe 5, the inlet 53 is provided at the other end of the feed pipe 5, and the rotating frame 52 is installed at the bottom of the storage box 1 and is rotatably connected to the rotating shaft 51.

[0036] The rotating frame 52 provides installation positioning for the feeding tube 5, and changes the inclination angle between the feeding tube 5 and the horizontal plane through the rotating shaft 51, ensuring that the bait in the feeding tube 5 can rely on gravity to tilt and accelerate, thereby speeding up the discharge speed of the bait from the feeding port 53.

[0037] See also Figures 1 to 6As shown, the delivery pipe 6 is provided with a boss 61, an inner tube 62, a delivery rod 63 and a gasket 64. The boss 61 is arranged at the top of the delivery pipe 6 and is on the water surface. The inner tube 62 is rotatably installed in the delivery pipe 6. The delivery rod 63 is arranged at the center of the inner tube 62, and the gasket 64 is installed at the top of the delivery pipe 6.

[0038] The boss 61 is used to connect the feeding pipe 5, the inner tube 62 rotates in conjunction with the delivery pipe 6, the delivery rod 63 is used to deliver the bait in the delivery pipe 6 to the bottom of the water against the water pressure, and the washer 64 is used to rotate the delivery pipe 6.

[0039] See also Figure 6 As shown, the inner tube 62 is provided with a through hole 621, a ring frame 622 and a motor 623. The through hole 621 array is arranged on the outer surface of the inner tube 62 and the conveying pipe 6, the ring frame 622 is installed at the bottom of the inner tube 62, and the motor 623 is installed at the top of the inner tube 62 and connected to the storage box 1.

[0040] The through hole 621 is used to discharge the bait in layers in the delivery pipe 6. When the delivery pipe 6 is rotated, the discharge speed of the bait from the through hole 621 is determined by the overlap between the through hole 621 on the inner tube 62 and the through hole 621 on the delivery pipe 6. The ring frame 622 is used to support the delivery pipe 6 to prevent it from falling to the bottom of the water. The motor 623 is used to fix the delivery rod 63 and provide power for it.
