[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 A wind-powered feeding automatic control device with noise reduction function comprises a feeding box 1, a feeding pipe 2, a control system 3, a sound absorbing panel 4, a shock absorbing seat 5 and a shock absorbing device. One side of the feeding box 1 is connected to the feeding pipe 2 through a flange 6, and the top of the feeding pipe 2 is connected to a feeding pipe 7. A chassis 8 is installed inside the feeding box 1, and a motor 9 is installed inside the chassis 8. A fan 10 is provided at the output end of the motor 9 through the chassis 8. Multiple groups of air inlet pipes 11 are installed on the top of the feeding box 1, and a muffler 12 is installed on the outside of the motor 9. The bottom of the feeding box 1 and the feeding pipe 2 The walls are all installed with support seats 13, and the two groups of support seats 13 share a sound absorbing board 4. The sound absorbing board 4 is installed with a shock absorbing seat 5 through the shock absorbing device. In this embodiment, the muffler 12 is used to reduce the noise generated when the motor 9 is running. The sound absorbing board 4 is a material and structure that can absorb sound, and there are many tiny holes on the surface. Therefore, the noise sound waves generated by the equipment will reflect part of the energy and absorb part of the energy during the propagation process, thereby reducing the noise generated by the equipment to the greatest extent, and can effectively reduce the sound energy of noise propagation, so as to achieve the effect of sound absorption, so that the device can achieve the function of noise reduction.

[0026] In actual use, in order to further reduce the noise generated by the vibration of the device during operation, in this embodiment, the shock absorbing device includes a damping cylinder 14, a damping rod 15 and a spring 16. The top wall of the shock absorbing seat 5 is provided with a groove 17, and the damping cylinder 14 is installed on the bottom wall of the groove 17. The damping rod 15 is slidably connected in the damping cylinder 14. The top wall of the damping rod 15 is connected to the bottom wall of the sound absorbing board 4. The spring 16 is installed on the outer wall of the damping rod 15 and the damping cylinder 14. The sound absorbing board 4 seat drives the damping rod 15 to move downward in the damping cylinder 14 and squeezes the spring 16. The rebound force of the spring 16 and the damping force of the inner cavity of the damping cylinder 14 are used to buffer the impact force to a certain extent. The shock absorbing device can reduce the transmission of structural vibration, thereby reducing structural noise, thereby improving the stability and reliability of the equipment, reducing the noise generated by vibration, suppressing the oscillation peak of the resonance frequency, and facilitating the damping of the device to achieve noise reduction.

[0027] In actual use, it is further convenient to control the operating status of the motor 9. In this embodiment, the control system 3 is arranged on the support seat 13, and the control system 3 is electrically connected to the motor 9. The control system 3 is used to monitor the operating status of the equipment and control the operation of the motor 9.

[0028] In actual use, in order to further reduce noise propagation, in this embodiment, the outside of the feeding box 1 and the feeding pipe 2 are wrapped with sound insulation cotton 18. The sound insulation cotton 18 wrapped around the outer wall of the feeding pipe 2 is a special sound insulation material, which can effectively reduce the ability of the feeding pipe 2 to conduct sound and achieve the purpose of sound insulation.

[0029] In actual use, the friction noise of the material in the feeding pipe 2 is further reduced. In this embodiment, the inner wall of the feeding pipe 2 is made of a smooth and wear-resistant pipe to reduce the friction noise of the material in the feeding pipe 2.

[0030] In actual use, the noise generated by the operation of the motor 9 is further reduced. In this embodiment, the motor 9 adopts a low-noise motor. The low-noise motor adopts a low-noise rotor material and an efficient structural design, so the noise is smaller than that of the ordinary motor 9, further reducing the noise generated by the operation of the motor 9.

[0031] In actual use, in order to further facilitate the detection of noise, in this embodiment, a noise detector is provided in the control system 3. The noise monitor can detect the noise in real time. When the noise exceeds a preset threshold, the operating state of the motor 9 is automatically adjusted to reduce the noise.

[0032] In actual use, in order to further facilitate the heat dissipation of the motor 9, in the present embodiment, a heat dissipation groove 19 is provided on the side of the feed box 1 away from the feed pipe 2. The design of the heat dissipation groove 19 can effectively increase the heat dissipation area of ​​the motor 9, so that the heat generated by the motor 9 during operation can be dissipated more quickly, thereby preventing the motor 9 from overheating.
