[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0034] An electric gear machine for an eel feed hopper in this embodiment relates to the technical field of aquaculture. By improving the internal structure and material of the gear machine, the noise is reduced and the volume is lightened.

[0035] See also Figures 1 to 5 In this embodiment, an electric gear machine for an eel feed hopper includes: an electric motor 100, a low-carbon steel gear set 200, a low-carbon steel support body 300 and a gear box 400. All three are encapsulated in the gear box 400 and are used to drive the mobile feeding of the eel feed hopper.

[0036] The motor 100 has a rotation output end, which can transmit the generated rotational motion to other devices.

[0037] The low carbon steel gear set 200 is composed of a plurality of low carbon steel gears 210 and corresponding low carbon steel gear shafts 220, and the low carbon steel gears 210 and the corresponding low carbon steel gear shafts 220 can cooperate with each other. One of the low carbon steel gear shafts 220 is fixedly connected to the rotation output end of the motor 100, and the other low carbon steel gear shafts 220 are used to adjust the speed ratio of the power output end of the motor 100. By adjusting the gear ratio, more precise power transmission and speed control can be achieved, so that the motor 100 can operate efficiently under different working conditions, thereby reducing the noise caused by overload or unstable operation of the motor 100, thereby significantly reducing the operating noise of the motor 100 and alleviating the stress response of the eel.

[0038] The mild steel support body 300 includes a mild steel panel body 310. The panel body 310 has a first mounting area for the motor 100 and a second mounting area for the mild steel gear set 200. These mounting areas are isolated from each other and accommodate the motor 100 and the mild steel gear set 200 separately, ensuring a tight fit and stable operation. The panel body 310 makes the entire electric gear machine more compact, reducing its size and weight, thereby alleviating the strain on the feeder's load capacity.

[0039] The gearbox 400 is a carbon fiber gearbox, which encapsulates the motor 100, the low-carbon steel gear set 200, and the low-carbon steel support body 300. Carbon fiber material has excellent lightweight properties. Compared with traditional metal materials, carbon fiber greatly reduces the weight of the gearbox 400 while maintaining strength. The weight reduction contributes to the portability and adaptability of the overall equipment and reduces the burden on the equipment support structure. Carbon fiber material has excellent strength and rigidity, enabling the gearbox 400 to withstand large mechanical loads and working stresses. Carbon fiber material is not easily corroded and has strong chemical corrosion resistance. It has a strong protective effect on the gearbox 400 used in humid or corrosive environments, which can improve the durability of the equipment and reduce maintenance costs. Compared with metal materials, carbon fiber has better vibration attenuation performance, which can effectively reduce the noise output of the gear transmission system and improve the comfort of the working environment.

[0040] It should be noted that the low-carbon steel gear set 200 and the low-carbon steel support body 300 are both made of low-carbon steel, which has good strength, hardness and toughness, is not prone to deformation, and has a long service life.

[0041] In some embodiments, see Figure 1The low carbon steel support body 300 further includes a low carbon steel auxiliary panel 320 for noise reduction. The low carbon steel auxiliary panel 320 is mounted on one side of the low carbon steel panel body 310. The thickness of the low carbon steel auxiliary panel 320 is greater than that of the low carbon steel panel body 310.

[0042] The mild steel auxiliary panel 320 is thicker than the mild steel panel main body 310, improving its overall mass and rigidity. This effectively absorbs and blocks the vibration and noise generated by the motor 100 and gear shaft during operation. The thicker material better dissipates energy and reduces noise transmission, further reducing the noise level of the gear motor 100. This creates a quieter living environment for the eels and reduces their stress response to noise.

[0043] The low-carbon steel auxiliary panel 320 is formed with a motor slot 321 for mounting the motor 100 and multiple shaft holes 322 for the shaft of the low-carbon steel gear 210 to pass through. The motor slot 321 and multiple shaft holes 322 provided on the low-carbon steel auxiliary panel 320 can partially enclose the motor 100 and the gear shaft, making the positioning of the motor 100 and the gear shaft more precise and effectively reducing the play (axial or radial movement) of the motor 100 and the gear shaft. With the relative reduction in play, the stability and transmission accuracy of the gear transmission system are improved, and the mechanical wear and operating noise caused by play are reduced.

[0044] In some embodiments, see Figure 1 The low-carbon steel auxiliary panel 320 forms an embedded arc-shaped structure corresponding to the motor slot body 321. The arc-shaped structure can prevent stress concentration. Stress concentration usually occurs at sharp corners or irregular shapes of the structure, which can easily lead to excessive local stress and cause material fatigue or fracture. By providing an embedded arc-shaped structure in the motor slot body 321, stress concentration can be effectively alleviated. The arc shape can evenly distribute the stress applied by the outside world and avoid stress concentration points caused by sharp angles, thereby reducing the risk of damage to the material near the motor 100 and the gear shaft.

[0045] The arc-shaped structure evenly distributes stress, preventing stress concentration and cracking or other fatigue damage to the entire mild steel auxiliary panel 320 during long-term use. This significantly improves the strength and durability of the supporting structure for the motor 100 and gear train, extending the overall service life of the equipment.

[0046] In some embodiments, the low-carbon steel auxiliary panel 320 has rounded corners in the area where the shaft hole 322 is installed. The area around the shaft hole 322 is prone to stress concentration, especially in high-load or vibration environments. Sharp edges can cause stress concentration, increasing the risk of material fatigue and damage. By providing rounded corners in the area where the shaft hole 322 is installed, stress can be effectively dispersed, reducing stress concentration and, consequently, the risk of material cracking or deformation.

[0047] The rounded corners reduce fatigue cracks caused by stress concentration and significantly improve the fatigue resistance of the auxiliary panel and its connections. This provides a more durable structure over long-term use, provides more stable support for the motor 100 and gear train, and extends the overall service life of the equipment.

[0048] In some embodiments, see Figure 1 The mild steel panel body 310 is provided with mounting holes 311 through which bolts can pass to connect the mild steel panel body and the gear box 400. With the help of the mounting holes 311 and the bolts, the mild steel panel body 310 and the gear box 400 can be easily disassembled and assembled, providing convenience for relevant personnel to repair the gear set.

[0049] The low-carbon steel gear assembly 200 and the low-carbon steel support body 300 are integrated as a module, meeting the requirements of standardization and modularization. During production and maintenance, no additional drilling or adjustment work is required, thereby reducing installation time and labor costs, and lowering the probability of error.

[0050] In some embodiments, see Figures 2 to 5 The motor 100 includes the motor 100 body and the gear transmission unit 120. The torque of the motor 100 body is transmitted to the mild steel gear set 200 through the gear transmission unit 120. The gear transmission unit 120, which is directly connected to the motor 100, has the highest speed and generates the most noise. By improving the structure of the gear transmission unit 120, the transmission efficiency can be improved, the noise intensity can be reduced, and the noise generated by the electric gear machine as a whole can be reduced.

[0051] As a further implementation, see Figure 3 and Figure 4 The gear transmission unit 120 includes a housing 121 and a planetary gear set 122 disposed within the housing 121. A water jacket 121b is provided in the housing 121 to reduce noise transmission. The water jacket 121b is filled with flowing fluid. The fluid can absorb and scatter sound waves, reducing the propagation of sound.

[0052] During operation, the fluid filling water jacket 121b absorbs and scatters the sound waves generated by planetary gear set 122, reducing direct noise transmission. The physical properties of the fluid medium effectively attenuate vibration noise, especially during high-speed gear rotation. By absorbing sound energy and converting it into tiny amounts of heat, the transmitted noise level is significantly reduced. This contributes to a quieter working environment, reduces stress reactions in sensitive environments, such as eels, and improves the device's adaptability in specialized environments.

[0053] While absorbing noise, the fluid also cushions and attenuates the vibrations generated during gear operation. Reduced vibration transmission reduces fatigue and wear on gear sets and other mechanical components, extending the overall life of the equipment and maintaining its long-term stable working condition.

[0054] The flowing fluid not only absorbs sound waves but also provides a certain damping effect, making the gear transmission unit 120 more stable during operation. The damping effect helps eliminate minor vibrations during operation, allowing the gear set to transmit power in a more stable manner, improving the operating efficiency and reliability of the equipment.

[0055] It should be noted that the ends of the housing 121 are connected to the mild steel panel body 310 via bolts, forming a relatively sealed housing 121 structure. The housing 121 can be fixedly connected to the mild steel panel body 310 to secure the motor 100. The relatively sealed housing 121 structure protects the planetary gear set 122 from external interference.

[0056] In some embodiments, see Figure 4 The inner wall of the box body 121 is provided with gear teeth to form a gear ring 121a. The gear ring 121a is arranged relative to the water jacket 121b. The gear ring 121a can increase the contact area between the inner wall of the box body 121 and the outside world. The water jacket 121b is arranged relative to the gear ring 121a, which can absorb the heat inside the box body 121 and prevent the planetary gear set 122 from overheating.

[0057] Planetary gear set 122 is mated with gear ring 121a, which is mounted directly on the inner wall of housing 121. This allows for more precise and stable meshing between the two gear rings, effectively reducing vibration and noise caused by poor gear meshing. This improves the accuracy and reliability of the transmission system and ensures smooth power output.

[0058] In some embodiments, see Figure 5The planetary gear set 122 includes a sun gear 122a, planetary gears 122b and a planetary carrier 122c. The sun gear 122a is connected to the rotation output end of the motor 100 body, and the planetary carrier 122c is connected to the low-carbon steel gear set 200. Multiple planetary gears 122b are arranged on the planetary carrier 122c and are meshed with the sun gear 122a. The motor 100 transmits the torque to the sun gear 122a. The sun gear 122a rotates and drives the planetary gears 122b to revolve along the gear ring 121a. When the planetary gears 122b revolve, the entire planetary carrier 122c is mobilized to rotate. While reducing the speed, the torque can be output more stably and the noise generation can be reduced.

[0059] It should be noted that the planetary gear set 122 can effectively resist instantaneous impacts and load changes due to its structural characteristics, ensuring the smooth operation of the system during operation and reducing noise generation.

[0060] Compared with a directly connected gear system, the planetary gear set 122 can increase the output torque during deceleration, thereby meeting application scenarios with higher driving force requirements and ensuring that the equipment can operate normally under heavier loads.

[0061] In some embodiments, see Figure 4 On either side of the housing 121 are provided a liquid inlet 121c and a liquid outlet 121d, each of which is connected to the water jacket 121b. Pipes and a pump connect both the inlet 121c and the outlet 121d to the aquaculture waters. The pump drives the water flow, providing circulating water in the water jacket 121b, absorbing noise while cooling the housing 121. Furthermore, the circulating water increases the dissolved oxygen content in the eel aquaculture waters, promoting their growth and reproduction.

[0062] The process begins by starting the water pump to supply circulating water to the water jacket 121b. Then, the motor 100 is activated, running at high speed and driving the planetary gear set 122, reducing the speed while stabilizing torque transmission. The water in the water jacket 121b continuously absorbs noise and cools the housing 121. The output of the planetary gear set 122 drives the mild steel gear set 200, further reducing the reduction ratio and automatically feeding the eel feed hopper.

[0063] The above description is only a preferred specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the present invention.
