DETAILED DESCRIPTION

[0019] like Figures 1 to 4As shown, a protective device for a conveyor belt drive motor, the drive motor 4 is arranged at a lower position on one side of the conveyor belt 1, the output end of the drive motor 4 is connected to the gear box 5, the gear box 5 is connected to the vertical output shaft 9, the upper end of the vertical output shaft 9 is connected to the drive shaft 6 of the conveyor belt 1 through a transmission gear, the drive motor 4 and the gear box 5 are arranged on a mounting plate 10, one end of the mounting plate 10 is arranged on the motor bracket 2 through a plurality of shock-absorbing pads, and the other end is connected to the motor bracket 2 through a vertical adjusting tube 11, and a protective shell 3 is provided on the outside of the drive motor 4 and the transmission gear.

[0020] The drive motor 4 is arranged at a lower position on one side of the conveyor belt 1, thereby avoiding the problem of lubricating oil leakage and product contamination caused by the motor being located above.

[0021] The driving motor 4 is connected to the transmission shaft 6 of the conveyor belt 1 through the gear box 5, the vertical output shaft 9 and the rotating gear, forming a stable transmission structure.

[0022] One end of the mounting plate 10 is arranged on the motor bracket 2 through a plurality of shock-absorbing pads, which can effectively reduce the vibration generated during the operation of the motor; the other end is connected to the motor bracket 2 through a vertical adjustment tube 11, which can fine-tune the position of the motor and facilitate the adjustment of the meshing clearance and meshing angle of the transmission gear, thereby improving the transmission efficiency and accuracy.

[0023] The driving motor 4 drives the conveyor belt 1 through the gear box 5 and the transmission gear. In order to facilitate the adjustment of the meshing clearance and meshing angle of the transmission gear, one end of the mounting plate 10 is set on the motor bracket 2 with the help of multiple shock-absorbing pads, and the other end is connected to the motor bracket 2 through a vertical adjustment tube 11, which can fine-tune the position of the motor. If it is found that the meshing of the transmission gear is not tight enough, the motor position can be fine-tuned through the adjustment tube 11 to achieve the ideal meshing state. Or when the meshing angle deviates, it can also be corrected by this fine-tuning method.

[0024] In the preferred embodiment, a second bevel gear 8 is provided at the upper end of the output shaft 9, and a first bevel gear 7 is provided at the end of the transmission shaft 6, and the first bevel gear 7 is meshed with the second bevel gear 8. The diameter of the first bevel gear 7 is larger than the diameter of the second bevel gear 8. The end of the mounting plate 10 close to the drive motor 4 is mounted on the motor bracket 2 by screws. Through the meshing of the first bevel gear 7 and the second bevel gear 8, effective power transmission is achieved to ensure stable operation of the conveyor belt 1. The diameter of the first bevel gear 7 is larger than the diameter of the second bevel gear 8, which can achieve a certain speed change effect and meet different transmission requirements. The design of the vertical output shaft 9 facilitates the precise meshing of the first bevel gear 7 and the second bevel gear 8, reduces transmission errors, and improves transmission efficiency.

[0025] In the preferred embodiment, a plurality of second shock-absorbing pads 15 are provided between the end of the mounting plate 10 close to the drive motor 4 and the motor bracket 2, and the first screw 16 passes through the mounting plate 10 and the second shock-absorbing pad 15 and is threadedly connected to the motor bracket 2. A plurality of second shock-absorbing pads 15 are provided between the end of the mounting plate 10 close to the drive motor 4 and the motor bracket 2, which can effectively absorb the vibration generated when the drive motor 4 is running and reduce the noise when the equipment is running. The first screw 16 passes through the mounting plate 10 and the second shock-absorbing pad 15 and is threadedly connected to the motor bracket 2, which ensures the stable connection between the mounting plate 10 and the motor bracket 2 while achieving shock absorption, thereby ensuring the stability of the motor when it is working.

[0026] During long-term operation, the second shock-absorbing pad 15 can reduce fatigue damage to equipment parts caused by vibration and extend the service life of the equipment; and the stable connection method can prevent the motor from loosening due to vibration, thereby ensuring the continuity and safety of production.

[0027] In the preferred embodiment, the first joint bearing 13 and the second joint bearing 14 are provided at both ends of the adjusting tube 11, the second screw 17 passes through the first joint bearing 13 and is connected to the other end of the mounting plate 10, the threaded section at the lower end of the first joint bearing 13 is threadedly connected to the adjusting tube 11, the threaded section at the upper end of the second joint bearing 14 is threadedly connected to the adjusting tube 11, and the third screw 18 passes through the second joint bearing 14 and is connected to the motor bracket 2. Figure 3 As shown,

[0028] The first joint bearing 13 and the second joint bearing 14 at both ends of the adjustment tube 11 can achieve angle adjustment, so as to accurately fine-tune the position of the motor, so that the meshing clearance and meshing angle of the transmission gear reach an ideal state, and significantly improve the transmission efficiency and accuracy.

[0029] The device can flexibly adapt to different working conditions and transmission requirements. When the load of the conveyor belt changes or the equipment has parts that wear out after a period of operation, resulting in a decrease in transmission accuracy, it can be corrected in time by adjusting the angle of the joint bearing.

[0030] Precise position fine-tuning effectively reduces errors caused by poor meshing of transmission gears, reduces energy loss, and improves the performance of the entire transmission system.

[0031] During the maintenance and commissioning of the equipment, the motor position can be adjusted conveniently and quickly, saving time and labor costs.

[0032] During the production process, if abnormal noise or overheating is found in the transmission, the problem can be quickly solved by adjusting the spherical bearing to avoid equipment failure and downtime.

[0033] In the preferred embodiment, the third screw 18 is sleeved with the first shock absorbing pad 12, and the first shock absorbing pad 12 is arranged between the second spherical bearing 14 and the motor bracket 2. It plays a buffering role, reduces the wear and fatigue damage caused by vibration to the third screw 18, the second spherical bearing 14 and the motor bracket 2, and prolongs the service life of these components.
