[0002] Aerator is a machine commonly used in fish farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be short of oxygen, and it can also inhibit the The aerator generally uses its own air pump to pump air into the water to increase the amount of oxygen in the water. The purpose of this is to reduce the amount of water in the gearbox. Traditional gearbox housings are often made of iron and are often submerged in water, which can lead to corrosion and failure. Typically, their service life is less than two years, and disassembly and maintenance are laborious and inconvenient. Utility Model Content

[0012] Figure 2 This is a schematic diagram of the shell body structure of the present utility model. DETAILED DESCRIPTION

[0013] like Figure 1-Figure 2 As shown, an aerator gearbox housing includes a shell body 1 and a sealing cover 2, with an enlarged opening for assembly and maintenance. The shell body 1 has an inlet port 3 and a secondary port 4 for power input on the top, and the shell body 1 has an outlet port 5 for power output on two opposite sides. The inlet port 3 serves as an assembly port for motor input, and the secondary port 4 is used to connect the required mechanism, and its caliber is generally small, while the outlet port 5 is used to connect the subsequent transmission mechanism for oxygenation. The bottom of the shell body 1 has an integrally connected fixed base 6, which is convenient for installation and fixation with fasteners, and can also ensure the structural strength of the connection. The inlet port 3 is provided with a sealing groove 7 for installation of the sealing cover 2, and the center of the sealing cover 2 is provided with a connection hole 8 for installation of the power supply motor. The sealing cover 2 is threadedly connected and fixed to the inlet port 3. The design of the sealing cover 2 is to ensure the sealing strength there, and to facilitate opening and closing for maintenance. The shell body 1 is formed as a whole by injection molding, which reduces weight and cost and can also meet structural strength requirements. A seal is provided between the sealing cover 2 and the shell body 1, typically a sealing ring or gasket, which will not be elaborated upon or limited herein. The walls of the sealing groove 7 are arranged in a stepped pattern, creating a labyrinth seal characteristic, whereby the medium passes through a tortuous and narrow passageway, achieving a throttling seal. Furthermore, the walls of the sealing groove 7 have an annular curved surface 9, which provides space for the installation of the seal and ensures a good fit. The shell body 1 is provided with a chamber connecting the various interface ports, which conforms to the external shape of the shell body 1.

[0014] The inlet port 3 and the sealing groove 7 are both disc-shaped structures. The chamber has a rectangular cavity 10 at the place where it communicates with the sealing groove 7, and the width of the cavity 10 is smaller than the inner diameter of the sealing groove 7. The shape of the inlet port 3 is consistent with the shape of the sealing cover 2 and the seal, which is convenient for installation and use, and the structural strength of this part is also improved. The relatively narrow size of the cavity 10 is conducive to supporting the sealing cover 2 during installation, and further constitutes the characteristics of the labyrinth seal. In addition, the use of sealing rings and the like when connecting the specific interface positions is a mature technical means. This embodiment mainly focuses on the sealing structure problem of the gearbox housing itself.

[0015] The secondary interface 4 is provided with first reinforcing ribs 11 on opposite sides, a second reinforcing rib 12 is provided between the housing body 1 and the base, and the outlet interface 5 is provided with evenly spaced third reinforcing ribs 13 along its outer edge. The outlet interfaces 5 are arranged in pairs on each side of the housing body 1, with a fourth reinforcing rib 14 connecting the outlet interfaces 5 on the same side, and a fifth reinforcing rib 15 is provided between the inlet interface 3 and the housing body 1. This strengthens the local structural strength, compensates for the deficiencies of the plastic material, particularly at the locations and joints of the interfaces, improves service life, and facilitates connection with motors and other mechanisms.

[0016] The four corners of the fixed base 6 are provided with slots 16 and fixing holes 17 located within the slots. The slots 16 and fixing holes 17 are designed for installation of the fixed base 6, saving installation space and not hindering use in compact environments. The bottom surface of the fixed base 6 is provided with hollow slots 18 distributed horizontally and vertically, eliminating the need for solidification while ensuring structural strength and enhancing toughness.
