A fixed block 6 is arranged on one side of the rotating block 5, and an adjusting mechanism 7 is arranged on the top of the rotating block 5, which can further seal the rotating shaft 4. A sealing mechanism 8 is arranged on the top of the adjusting mechanism 7, which can prevent dust from entering the interior of the equipment, and a screw 9 is arranged on the top of the sealing mechanism 8.

[0031] Reference Figure 2 and Figure 3 The adjusting mechanism 7 includes a first baffle, a second baffle 11 is provided at the bottom of the first baffle 10, a first sealing ring 12 is provided on one side of the second baffle 11, a first spring 13 is provided on one side of the second baffle 11, and an elastic member 14 is provided at the bottom of the second baffle 11, which can be deformed so as to always fit with the outer surface of the rotating shaft 4. A second sealing ring 15 is provided at the bottom of the first baffle 10, which can further seal the rotating shaft 4, thereby extending the service life of the equipment. One end of the first spring 13 is fixedly connected to the second baffle 11, and the other end of the first spring 13 is fixedly connected to the second baffle 11, which can squeeze the first baffle 10 and the second baffle 11, thereby improving the sealing effect. The first baffle 10 is fixedly connected to the connecting tube 3, which can make the second baffle 11 move, thereby improving the sealing effect, thereby extending the service life of the equipment.

[0034] The implementation principle of this embodiment is:

[0035] The bucket elevator head and tail sealing structure is provided with a mounting seat 1, and the mounting seat 1 is installed on the outer shell of the elevator by screws. When the rotating shaft 4 rotates, the rotating shaft 4 can drive the rotating block 5 to rotate, and the rotation of the rotating block 5 can drive the external thread 21 to rotate. Since the fixed block 6 is fixed, the rotating block 5 and the fixed block 6 can rotate relative to each other, and the external thread 21 and the thread groove 22 can rotate relative to each other, which can drive the lubricating oil inside to rotate, and the rotating shaft 4 can be sealed, thereby preventing the equipment from leaking, preventing the equipment from being damaged, and extending the service life of the equipment.

[0036] An adjusting mechanism 7 is provided, which can squeeze the first baffle 10 through the connecting tube 3, so that the first baffle 10 can squeeze the first sealing ring 12. At this time, the first sealing ring 12 will squeeze the second baffle 11, so that the second baffle can be moved. The movement of the second baffle 11 can squeeze the first spring 13, so that the second spring 17 can squeeze the first baffle 10, so that the first baffle can be moved, and then the second sealing ring 15 can be squeezed, so that the second sealing ring 15 can be fitted with the rotating shaft 4, and the elastic member 14 can be deformed, so that the rotating shaft 4 can be sealed, and the rotating shaft 4 can be further sealed, so as to extend the service life of the equipment.

[0037] A sealing mechanism 8 is provided. When the end cover 16 is connected to the connecting tube 3, the end cover 16 will move downward. The downward movement of the end cover 16 can squeeze the second spring 17, thereby causing the second spring 17 to deform, thereby causing the movable plate 18 to move downward. The downward movement of the movable plate 18 can squeeze the sealing filler 19, thereby squeezing the rotating shaft 4, and the second spring 17 can continuously apply pressure to the sealing filler 19, thereby causing the sealing filler 19 to finally fit with the outer surface of the rotating shaft 4, thereby preventing dust from entering the interior of the device, thereby extending the service life of the device.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The bucket elevator head and tail sealing structure, the rotating block 5 and the fixed block 6, can rotate relative to each other, thereby enabling the lubricating oil to rotate, and can seal the inside of the rotating shaft 4, thereby preventing the equipment from leaking. An adjusting mechanism 7 is provided, and the rotating shaft 4 can be further sealed by the adjusting mechanism 7, thereby extending the service life of the equipment;

[0040] 2. The bucket elevator head and tail sealing structure is provided with a sealing mechanism 8, through which the outside of the rotating shaft 4 can be sealed, thereby preventing dust from entering the interior of the equipment, and the second spring 17 can squeeze the honey-sealed filler, thereby extending the service life of the sealing point material and thereby extending the service life of the equipment.
