An adjusting strip 62 is fixedly connected to the outer wall of the adjusting roller 61. One side of the adjusting strip 62 is in contact with one side of the outer wall of the feed pipe 29. One end of the feed pipe 29 is fixedly connected to the middle of the upper end of the protective shell 1.
[0032] In this embodiment, through the arrangement of the storage box 2 and the adjustment box 6, when the lubricating oil between the upper worm gears is exhausted during the operation of the multi-head worm gear reducer, the adjustment roller 61 is pushed. The adjustment roller 61 slides in the sliding groove 63, and the factory air enters the connecting pipe 27 through the vent pipe 28. Under the conditions of height and air pressure, the lubricating oil in the storage box 2 is squeezed out, and one end of the feed pipe 29 drips the lubricating oil onto the first worm gear reducer shaft 11. The cooperation between the storage box 2 and the adjustment box 6 can add lubricating oil between the first worm gear reducer shaft 11 and the drive worm shaft 13, thereby reducing the probability of damage to the worm gears during operation.

When the reducer is running, it will rotate the second fan 53, which will circulate the lubricating oil inside the protective shell 1. The cooperation between the semiconductor heat sink 41 and the second fan 53 can further cool down the worm gear and reduce the number of times the worm gear needs to be replaced. When the semiconductor heat sink 41 is in use, the temperature on the other side will be very high. The first fan 4 is turned on, which increases the airflow speed next to the semiconductor heat sink 41 to cool down the semiconductor heat sink 41 and reduce damage to the semiconductor heat sink 41. The side of the semiconductor heat sink 41 that is cooled is inside the protective shell 1.
[0035] Example 3: According to Figure 1-5As shown, a mounting base 14 is provided at the lower end of the protective shell 1. Buffer rubber pads 15 are fixedly connected to the four corners of the lower end of the mounting base 14. A mounting platform 3 is fixedly connected to the upper end of the mounting base 14.

[0036] In this embodiment, by setting the rotating block 31 and the limiting block 35, when the components inside the protective shell 1 need to be inspected and replaced after long-term use of the equipment, the rotating block 31 is turned, and the sliding rod 37 rotates in the mounting groove 33. At the same time, the sliding rod 37 is pulled, and the limiting block 35 is taken out from the limiting hole 32 and the limiting groove 16. The other three rotating blocks 31 are operated in the same way.

[0037] The operating method and working principle of this device are as follows: When the multi-head worm gear reducer is running, when the lubricating oil between the upper worm gears is exhausted, the adjusting roller 61 is pushed first. The adjusting roller 61 slides in the sliding groove 63. The factory air enters the connecting pipe 27 through the vent pipe 28. Under the conditions of height and air pressure, the lubricating oil in the storage tank 2 is squeezed out. One end of the feed pipe 29 drips the lubricating oil onto the first worm gear reducer shaft 11. When the temperature inside the protective shell 1 is high, the semiconductor heat sink 41 is turned on to cool down the protective shell 1. When the reducer is running, it will rotate the second fan 53. The second fan 53 will circulate the lubricating oil inside the protective shell 1. The cooperation between the semiconductor heat sink 41 and the second fan 53 can further improve the lubricating oil circulation in the worm gear reducer. The worm gear is cooled, reducing the frequency of worm gear replacement. When the semiconductor heat sink 41 is in use, the temperature on the other side will be very high. Turning on the first fan 4 increases the airflow speed next to the semiconductor heat sink 41, cooling the semiconductor heat sink 41 and reducing damage to the semiconductor heat sink 41. When the components inside the protective shell 1 need to be inspected or replaced after long-term use of the equipment, the rotating block 31 is turned, and the sliding rod 37 rotates in the mounting groove 33. At the same time, the sliding rod 37 is pulled, and the limiting block 35 is taken out from the limiting hole 32 and the limiting groove 16. The other three rotating blocks 31 are operated in the same way. The cooperation between the rotating block 31 and the limiting block 35 makes it easy to disassemble the reducer and improves maintenance efficiency.
