[0030] It also includes a self-lubricating mechanism for lubricating the shaft of the rotor 2;

[0031] The self-lubricating mechanism comprises an oil box 6, the oil box 6 is fixedly mounted on the surface of the hood 1, a sliding shaft 4 is slidably connected in the oil box 6, a through hole 7 is provided on the surface of the oil box 6, the sliding shaft 4 passes through the through hole 7 and is slidably connected to the oil box 6 through a spring, a pressure block 3 is fixedly connected to the surface of the sliding shaft 4 that passes through the oil box 6, a circular arc angle is provided on the surface of the pressure block 3, and the cross section of the sliding shaft 4 is rectangular;

[0032] The end of the sliding shaft 4 located in the oil box 6 is fixedly connected with a pressure plate 10, the surface of the oil box 6 is connected with an oil filling hole 13, the surface of the oil box 6 is connected with an oil outlet pipe 14, the oil outlet pipe 14 is provided with an elastic membrane 15, and the surface of the elastic membrane 15 is provided with shrinkage holes;

[0033] The support rod 8 is fixedly installed on the surface of the rotor 2 by bolts, and the surface of the support rod 8 is fixedly connected with the pressure shaft 5, and the side of the pressure block 3 with a circular arc angle contacts the pressure shaft 5; when working, the rotor 2 rotates in the hood 1, and the rotating shaft outside the hood 1 drives the support rod 8 to rotate, and at the same time, the support rod 8 drives the sliding shaft 4 to rotate, and squeezes the pressure block 3 through the sliding shaft 4, so that the pressure block 3 drives the sliding shaft 4 to slide downward, and at the same time, the sliding shaft 4 drives the pressure plate 10 to squeeze the lubricating oil in the oil box 6, so that the lubricating oil passes through the oil outlet pipe 14, and the lubricating oil is discharged. The oil is sprayed onto the rotating shaft of the rotor 2 to achieve the effect of self-lubrication, reduce wear and reduce the replacement frequency of the rotor 2. At the same time, the impurities on the surface of the rotating shaft can be washed away by the oil spray. The sliding shaft 4 is set to a rectangle so that it can only slide up and down but cannot rotate, so as to avoid the pressure shaft 5 being unable to squeeze the arc angle on the surface of the pressure block 3. The elastic membrane 15 set in the oil outlet pipe 14 has the shrinkage hole on the surface opened under the action of oil pressure, so that the lubricating oil flows out. After the sliding shaft 4 is reset under the drive of the spring, the oil pressure in the oil box 6 disappears, and the elastic shrinkage hole is closed, so as to avoid the lubricating oil in the oil box 6 from flowing out.

[0034] Two support rods 8 are provided, and a pair of the support rods 8 are symmetrically distributed with respect to the central axis of the rotor 2.

When the notch 22 on the surface of the sliding shaft 4 moves to the position of the rubber ring 11, the rubber ring 11 will restrict the sliding shaft 4, delaying the reset time of the sliding shaft 4, thereby preventing the lubricating oil from being sprayed out at a higher frequency and causing waste.

[0035] Embodiment 2

[0036] See also Figure 4-6 As shown, in contrast to Example 1, as another embodiment of the present utility model, a recovery box 19 is provided on the surface of the hood 1, a cardboard 21 is provided on the surface of the recovery box 19, a filter screen 20 is fixedly connected to the surface of the cardboard 21, and the filter screen 20 is a sponge block.

[0037] During operation, excess lubricating oil is collected through the recovery box 19 to prevent the leaked lubricating oil from flowing freely, which is inconvenient for the staff to clean up. At the same time, the lubricating oil is filtered through the sponge block for subsequent reuse. The detachable sponge block is easy to replace to ensure the filtering effect. The guide bar 24 can guide the lubricating oil. At the same time, the guide bar 24 lower than the slot 22 is combined with the chamfer to prevent the lubricating oil from hanging on the wall, which is inconvenient to remove the card plate 21.

[0038] At least two plug plates 17 are fixedly connected to the surface of the recovery box 19, and a fixing block 18 is fixedly connected to the surface of the hood 1 relative to the plug plates 17. The fixing block 18 cooperates with the plug plates 17 to fix the recovery box 19. During operation, the recovery box 19 can be disassembled by cooperating with the plug plates 17 and the fixing block 18, so that the staff can recover the lubricating oil and clean the recovery box 19.

[0039] Working principle: the rotor 2 rotates in the hood 1, and the rotating shaft outside the hood 1 will drive the support rod 8 to rotate. At the same time, the support rod 8 drives the sliding shaft 4 to rotate, and the sliding shaft 4 squeezes the pressure block 3, so that the pressure block 3 drives the sliding shaft 4 to slide downward. At the same time, the sliding shaft 4 drives the pressure plate 10 to squeeze the lubricating oil in the oil box 6, so that the lubricating oil passes through the oil outlet pipe 14 and sprays the lubricating oil to the rotating shaft of the rotor 2, so as to achieve the effect of self-lubrication, reduce wear and reduce the replacement frequency of the rotor 2. At the same time, the impurities on the surface of the rotating shaft can be washed away by oil spraying. The sliding shaft 4 is set to a rectangle so that it can only slide up and down but not rotate, so as to avoid the pressure shaft 5 from squeezing the arc angle on the surface of the pressure block 3. The elastic membrane 15 set in the oil outlet pipe 14 opens the shrinkage hole on the surface under the action of oil pressure, so that the lubricating oil flows out. After the sliding shaft 4 is reset under the drive of the spring, the oil pressure in the oil box 6 disappears, and the elastic shrinkage hole closes, so as to avoid the lubricating oil in the oil box 6 from flowing out.

[0040] The sliding shaft 4 slides downward, and when the notch 22 on the surface of the sliding shaft 4 moves to the position of the rubber ring 11, the rubber ring 11 will restrict the sliding shaft 4, delaying the reset time of the sliding shaft 4, thereby preventing the lubricating oil from being sprayed out at a high frequency, causing waste;

[0041] Excess lubricating oil is collected by the recovery box 19 to prevent the leaked lubricating oil from flowing freely, which is inconvenient for the staff to clean up. At the same time, the lubricating oil is filtered by the sponge block for subsequent reuse. The detachable sponge block is easy to replace to ensure the filtering effect. The guide bar 24 can guide the lubricating oil. At the same time, the guide bar 24 lower than the slot 22 is combined with the chamfer to prevent the lubricating oil from hanging on the wall. It is inconvenient to remove the card plate 21. The recovery box 19 can be disassembled by the plug plate 17 and the fixing block 18, which is convenient for the staff to recover the lubricating oil and clean the recovery box 19.
