Description

Technical Field

[0001] This invention relates to the field of aquaculture, and in particular to an aeration and feeding mixing device for aquaculture. Background Technology

[0002] Aquaculture is the practice of raising aquatic economic animals and plants using aquatic waters available for cultivation (including planting), according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions, and employing aquaculture technologies and facilities. It is one of the agricultural production sectors.

[0003] A feeding aeration pump is an aquaculture device that combines an aeration pump and a feeding machine. It can both feed the fish and aerate the water. However, existing feeding aeration pumps are mostly fixed in structure, which means they can only feed the fish in a fixed direction and aerate the water in a fixed area. The aeration and feeding area is relatively limited. Therefore, an aquaculture aeration and feeding mixing device is proposed. Summary of the Invention

[0004] To overcome the above-mentioned technical problems, the present invention provides an aeration and feeding mixing device for aquaculture.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an aquaculture oxygenation and feeding mixing device, including a driving device, a feeding device, and an oxygenation device; The driving device includes a support plate and a rotating plate. The top of the support plate is connected to the rotating plate via a slewing bearing. The rotating plate is cylindrical in shape. A dual-axis motor is installed on the rotating plate. Both output ends of the dual-axis motor are connected to propellers. The lowest side of the propellers is lower than the rotating plate. One end of a support plate is connected to the side of the rotating plate, and a buoyancy block is fixedly connected to the other end of the support plate. The feeding device includes a feeding cylinder, on which a support plate is connected to the bottom via a telescopic rod. A first through hole is located at the top of the feeding cylinder, and a feeding tube and a rotating support are located at the first through hole. The rotating support includes an inner ring and an outer ring. The inner side of the inner ring is fixedly connected to the outer wall of the feeding tube. The inner and outer rings are rotatably connected by rolling elements, which are in two layers. Two outer rings are connected via a connecting rod, and each outer ring is connected to one of the upper or lower layers of rolling elements. Gear teeth are located on the outer side of the inner ring between the two outer rings. A drive motor is fixedly connected inside the feeding cylinder, and a drive gear is located at the output end of the drive motor, meshing with the gear teeth. The feeding cylinder contains an intermediate cylinder, a storage cylinder, a rotary motor, and a drainage pump. The intermediate cylinder has a second through hole for use with the feeding pipe. A lifting rod is located inside the intermediate cylinder, and a sealing block is located at the lifting end of the lifting rod. The sealing block cooperates with the opening of the feeding pipe. The top opening of the storage cylinder is located outside the feeding cylinder. The bottom of the storage cylinder is connected to a discharge pipe via a one-way valve. The bottom of the discharge pipe is connected to a conveying pipe, which is connected to the intermediate cylinder. An auger is located inside the conveying pipe, and the output shaft of the rotary motor is fixedly connected to the auger. One end of the inlet pipe of the drainage pump is located inside the intermediate cylinder, and one end of the drain pipe of the drainage pump is located outside the feeding cylinder. The oxygenation device includes an oxygenation pump, an air inlet pipe, and an air delivery pipe. The oxygenation pump is fixedly installed inside the feeding cylinder. One end of the air inlet pipe passes through the support plate and is located on the top surface of the support plate. The other end of the air inlet pipe is connected to the input end of the oxygenation pump. One end of the air delivery pipe is connected to the output end of the oxygenation pump. The other end of the air delivery pipe is connected to the inside of the intermediate cylinder through an electronic valve.

[0006] Preferably, the cross-sectional shape of the delivery tube is Y-shaped.

[0007] Preferably, the rolling element is a ball or a roller.

[0008] Preferably, the cross-sectional shape of the sealing block is hexagonal or spherical.

[0009] Preferably, the discharge pipe is provided with a through hole, and a rotating shaft is provided in the through hole. The part of the rotating shaft located inside the discharge pipe is provided with a stirring rod. One end of the rotating shaft is connected to the outer wall of the intermediate cylinder through a bearing, and the other end of the rotating shaft is provided with a driven gear. The output shaft of the rotary motor is provided with a driving gear, and the driving gear and the driven gear are connected by a chain.

[0010] Preferably, the top opening of the storage cylinder is connected to the cover via a threaded connection.

[0011] The beneficial effects of the present invention are as follows: 1. When the device is placed on the water surface, the support plate can float on the water surface under the action of the buoyancy block. The operation of the dual-shaft motor drives the propellers on both sides to rotate, which can drive the device to move on the water surface. The rotation of the slewing bearing drives the propeller to adjust the direction, which can adjust the forward direction of the device. When the slewing bearing rotates, the position of the buoyancy block is adjusted by the support plate at the same time, so that the entire device is in a balanced state.

[0012] 2. As the propeller rotates and drives the bearing plate forward, the one-way valve opens, and the feed enters the discharge pipe through the one-way valve. The rotating motor drives the rotating shaft and stirring rod to rotate via the chain, stirring the feed. After the feed is mixed, it enters the conveying pipe. Under the action of the auger, the feed is conveyed to the intermediate cylinder. The lifting rod drives the sealing block away from the inlet of the feeding pipe, and water enters the intermediate cylinder. The feed enters the feeding pipe under the action of gravity, and under the action of the rotating support driving the feeding pipe to rotate, it spreads and sprinkles into the water, increasing the feeding range. After the feeding is completed, the sealing block enters the inlet of the feeding pipe, and the drainage pump runs to drain the water inside the intermediate cylinder.

[0013] 3. When oxygenation of the water is required, the lifting rod moves the sealing block away from the inlet pipe, water enters the intermediate cylinder, the oxygenation pump runs, air is injected into the water in the intermediate cylinder and discharged into the water through the inlet pipe, or the oxygen-rich water in the intermediate cylinder can be discharged into the water through the drain pump to carry out the oxygenation operation.
