[0023] In use, first make the box 1, then according to the box 1 front and rear reserved hole cover window 2, cover window 2 length size and height size are less than the reserved hole length size and height size 3mm, that is, cover window 2 can be through the reserved hole and the gap is small, further install the full enclosed shaft device 6 to the outside of the slide plate sealing device 4, further install the slide plate sealing device 4 in the slide groove 201 of the cover window 2 and adjust the height using the tensioning device 3, further use multiple slide plate pressing device 5 to press the slide plate sealing device 4 outside the cover window 2, at this time all the accessories on the cover window 2 are installed, further put the shaft 7 of the assembled traction wheel 8 into the box 1 and roughly adjust the position angle, the specific operation is, if the box 1 is not installed inside the hopper conveyor belt 9 and other accessories, then the shaft 7 can be lifted into the box 1 from the top through the crane, and then the bearing 603 is directly lifted in the box 1 and adjusted, if the box 1 has installed the hopper conveyor belt 9 and other accessories, then the shaft 7 is put into the hole opened in front and rear of the box 1 for installing the cover window 2 and directly hung below the hopper conveyor belt 9 and then adjusted, at this time the position of the shaft 7 is required to be about the position of the design drawing but offset to the rear, further the cover window 2 in front and rear is connected with the shaft 7 through the full enclosed shaft device 6, at this time the rear cover window 2 is outside the box 1 but the front cover window 2 is inside the box 1, further the worker lifts up the shaft 7 together with the cover window 2 through the crane or other lifting device through the full enclosed shaft device 6 at both ends of the shaft 7 and corrects the position to make the front and rear cover window 2 embedded in the hole opened in front and rear of the box 1, if the lifting equipment cannot meet the above operation, directly weld the handle on the outer surface of the cover window 2 and lift it manually, finally fix the cover window 2 with the box 1 through the bolt and nut, and then adjust the height of the shaft 7 and the tensioning hopper conveyor belt 9 by adjusting the height of the two height adjusting nuts 302 of the tensioning device 3, in this process, because the slide plate pressing device 5 is in contact with the slide plate sealing device 4 through the graphite block 503, the friction is small, so even if the slide plate sealing device 4 is always in the state of being pressed by the slide plate pressing device 5, the height can be directly adjusted, because the both ends of the shaft 7 have been sealed through the full enclosed shaft device 6, so the dust will not leak from the shaft head during use.
[0024] In summary, the totally closed elevator tightly presses the sliding plate sealing device 4 against the outer surface of the cover window 2 through the sliding plate pressing device 5 installed on both sides of the cover window 2 to reduce the gap between the fitting surfaces and further improve the sealing effect. Since the sliding plate pressing device 5 is in contact with the sliding plate sealing device 4 through the graphite block 503 of the head and the friction force is relatively small, the height of the sliding plate sealing device 4 can be directly changed through the tensioning device 3 without loosening the sliding plate pressing device 5, and further the effect of good sealing effect and convenient adjustment of the tightness degree is realized. The two oil seals 606 built in the totally closed shaft device 6 isolate the leakage of dust, and even if a small amount of dust adheres to the lubricating oil, it is finally mixed with the grease into a gel and discharged from the exhaust hole 607.
