Description

Technical Field

[0001] This utility model relates to the field of crayfish farming, specifically an aerator for crayfish farming. Background Technology

[0002] Lobster is rich in nutrients, high in protein, low in fat, and contains many essential trace elements that help stabilize the nervous system and maintain normal organ function. The astaxanthin in lobster meat is one of the most powerful antioxidants among all natural foods, preventing aging and leading to its development into health supplements. In traditional Chinese medicine, lobster can relieve coughs and phlegm, and also aid in wound healing for surgical patients. Currently, lobsters are mainly farmed in ponds and rice paddies, with pond farming being the most common method.

[0003] Current aerators used in crayfish farming, as described in patent CN210782590U, include a float plate, a fan on the upper surface of the float plate, and the base of the fan connected to the float plate; a float tube on the lower edge of the float plate, with its sidewall connected to the float plate; a ventilation pipe on the lower surface of the float plate, one end of which is connected to the air outlet of the fan, and the other end of which is an air outlet pipe. The air outlet pipes are interwoven to form a mesh structure, one side of which is connected to the ventilation pipe, and the other side of which is provided with an air outlet hole.

[0004] Regarding the aforementioned technologies, the inventors believe that placing the microporous aerator head in water can lead to problems. Since the water in shrimp ponds often contains a large number of impurities, and the microporous aerator head remains in the water for an extended period after aeration, the impurities in the water can easily clog the microporous aerator head, which can reduce the service life of the entire aerator. Utility Model Content

[0005] The purpose of this invention is to provide an aerator for crayfish farming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4An aerator for crayfish farming includes an aeration mechanism 1, which comprises a hollow box 101. A float 102 is fixedly connected to the bottom of the hollow box 101, and the float 102 is designed to float the entire aerator in water using its own buoyancy. An aeration pump 103 is fixedly connected to the inner top wall of the hollow box 101. An air inlet pipe 104 is fixedly connected to the input end of the aeration pump 103, and the air inlet pipe 104 passes through the top of the hollow box 101. An air distribution pipe 108 is fixedly connected to the output end of the aeration pump 103, and the air distribution pipe 108 is fixedly connected to the hollow box 101. The aeration pump 103 is designed to draw air from inside the air inlet pipe 104 into the air distribution pipe 108 when it starts working.

[0025] A support block 105 is fixedly connected to the outer side of the air intake pipe 104. The support block 105 is fixedly connected to the hollow box 101. The support block 105 is provided to further support the air intake pipe 104, thereby improving the stability of the air intake pipe 104. The end of the air intake pipe 104 away from the hollow box 101 is set downwards to reduce the probability of rainwater flowing into the air intake pipe 104. The end of the air intake pipe 104 away from the aeration pump 103 is threadedly connected to a threaded pipe 106. A filter screen 107 is fixedly connected to the bottom of the threaded pipe 106. The filter screen 107 is provided to filter the air drawn into the air intake pipe 104 to reduce the probability of debris being drawn into the air intake pipe 104.

[0026] Multiple connecting pipes 111 are fixedly connected in a ring array on the outer side of the air distribution pipe 108. A rotary joint 109 is fixedly connected to the end of each connecting pipe 111 furthest from the air distribution pipe 108. An L-shaped pipe 110 is fixedly connected to the end of each rotary joint 109 furthest from the air distribution pipe 108. The L-shaped pipe 110 penetrates the hollow box 101. The rotary joint 109 connects the connecting pipe 111 to the L-shaped pipe 110, allowing air from the air distribution pipe 108 to be discharged into the interior of the L-shaped pipe 110 through the guiding flow of the connecting pipe 111 and the rotary joint 109. Multiple aeration nozzles 113 are evenly fixedly connected to the outer side of the L-shaped pipe 110. The aeration nozzles 113 allow air to be discharged from the interior of the L-shaped pipe 110, thereby aerating and oxygenating the shrimp pond.

[0027] A vent pipe 112 is fixedly connected to the top of the hollow box 101. The end of the vent pipe 112 away from the hollow box 101 faces the hollow box 101. The vent pipe 112 allows the hollow box 101 to communicate with the outside, facilitating heat dissipation when the aeration pump 103 is working. The adjustment mechanism 2 includes a driving bevel gear 201 rotatably connected to the outside of the air distribution pipe 108. Each set of L-shaped pipes 110 has a driven bevel gear 205 fixedly connected to its outer side, meshing with the driving bevel gear 201. The driving bevel gear 201 is used to drive each set of driven bevel gears 205 and each set of L-shaped pipes 110 to rotate during rotation, thereby adjusting the L-shaped pipes 110 and the aeration nozzles 113 to be out of the water, thus reducing the probability that the aeration nozzles 113 will be easily clogged by impurities in the water if they are submerged for a long time.

[0028] Each driven bevel gear 205 has a rotating tube 206 fixedly connected to its opposite side. The rotating tube 206 is fixedly connected to the L-shaped tube 110. Each rotating tube 206 is rotatably connected to the hollow box 101. Each rotating tube 206 has an L-shaped plate 207 fixedly connected to its opposite side. The end of each L-shaped plate 207 away from the rotating tube 206 is fixedly connected to the L-shaped tube 110. The rotating tube 206 and L-shaped plate 207 provide auxiliary support for the L-shaped tube 110, reducing the probability of deformation. A worm gear 202 is fixedly connected to the top of the driving bevel gear 201. A worm 203 is meshed with the outer side of the worm gear 202. The worm 203 is designed to drive the worm gear 202 and the driving bevel gear 201 to rotate during rotation. A stepper motor 204 is fixedly connected to one side of the interior of the hollow box 101. The output end of the stepper motor 204 is fixedly connected to one end of the worm gear 203. The stepper motor 204 is configured to drive the worm gear 203 to rotate when the machine starts working.

[0029] In use, place the entire aerator in the shrimp pond water, allowing it to float on the surface under the buoyancy of the float plate 102. Then, start the aeration pump 103, which draws outside air through the air inlet pipe 104 into the air distribution pipe 108. Air is then discharged through the connecting pipes 111 into the L-shaped pipes 110, and finally into the shrimp pond water through the aeration nozzles 113, thus aerating the shrimp pond. After aeration, the next step can be started. The stepper motor 204 drives the worm gear 203 to rotate, which in turn drives the worm wheel 202 and the driving bevel gear 201. The driving bevel gear 201, in turn, drives each set of driven bevel gears 205 and the L-shaped tube 110 to rotate until the L-shaped tube 110 is adjusted to be out of the water surface. At the same time, each set of aeration nozzles 113 is also out of the water surface, which reduces the probability that the aeration nozzles 113 will be blocked by some debris in the water due to long-term immersion in the water.

[0030] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
