The pressure at the both ends of one piston 23 is different, and then drives and be slidably connected between first piston 23 and sleeve 21, makes first piston 23
It is slidably connected between driving hydraulic axis 22 and end cap 5, and then earth scraper is driven to promote；When first piston 23 drives hydraulic axis 22 to stretch
Out when end cap 5, the accommodating cavity between first piston 23 and end cap 5 becomes smaller, and makes the inside of air indentation Transmission Room 45, Transmission Room
Pressure inside 45 increases and then drives to be slidably connected between second piston 46 and Transmission Room 45, and second piston 46 is to wirerope 44
It does not limit, clockwork spring 49b, which resets, pulls wirerope 44 that second piston 46 is driven to reset, while clockwork spring 49b driving drive sleeve 49a is around end
It is rotatablely connected between lid 5, and then is slidably connected between the scraper plate 49 on drive sleeve 49a and hydraulic axis 22, make on cleaning set 49d
Lubrication, which has, to be uniformly applied in hydraulic axis 22, while the driving of second piston 46 is by the space of the Transmission Room 45 of one end of proximal cover 5
Becoming larger, passes the gas through check valve 47 and stomata 42 is discharged, gas is quickly discharged through air passing hole 42, brushes in hydraulic axis 22,
It smears the lubricating oil in hydraulic axis 22 uniformly, further improves lubricating quality, while avoiding hydraulic
The scrap such as cinder are gathered in hydraulic axis 22 in 22 dither process of axis；When hydraulic axis 22 is shunk, first piston 23 and sleeve 21
Memory space by the direction of proximal cover 5 becomes larger, and then the gas of the inside for a Transmission Room 45 for deviating from end cap 5 is made to enter set
Cylinder 21, and then under atmospheric pressure, second piston 46 drives wirerope 44 to pull drive sleeve 49a rotation, and drive sleeve 49a turns
Dynamic driving clockwork spring 49b is shunk, while air enters a biography by proximal cover 5 from filter screen 3 by another check valve 47
Dynamic room 45, filter screen 3 are hemispherical dome structure, effectively prevent scrap from assembling on filter screen 3 in 5 dither process of end cap, liquid
It is slided between last item 22 and dedusting set 41, dedusting set 41 deviates from the thickness of the end of end cap 5 from end cap 5 to the side for deviating from end cap 5
To being gradually reduced, and then convenient for preliminary cleaning waste residue, avoids scrap and assemble in hydraulic axis 22, while on drive sleeve 49a
Scraper plate 49 clears up dust, is discharged from through-hole 43, and drive sleeve 49a circumference array in the inner circle circumferential direction of dedusting set 41 is equipped with
Multiple sections are the scraper plate 49 of isosceles trapezoid, and the direction that the area of section of scraper plate 49 covers 41 from sleeve 21 to dedusting is gradually reduced,
It using the principle of ploughshare, slides waste residue toward the direction away from end cap 5, and then keeps the cleaning efficiency of dust higher, mention significantly
The stability that high hydraulic axis 22 and sleeve 21 slide；When adding lubricating oil, sealing-plug 62 is turned, it is past by charge pipe 61
The inside addition lubrication of locker room 63 has, and when drive sleeve 49a is rotated, the convex block 48 on drive sleeve 49a contradicts drive block 64, makes to pass
Oil filler point 65 and locker room 63 on motion block 64 are connected, and reset spring 69b is shunk, and lubricating oil is made to enter the inside of holding tank 66,
Retaining ring 68 is contacted with the end of fiber sliver 67 with the lubricating oil of the inside of holding tank 66, and lubrication is made to have sucking cleaning set 49d's
Inside carries out coating lubricating oil to hydraulic axis 22 by cleaning set 49d, and retaining ring 68 is hemispherical dome structure, is avoided in centrifugal force
Under the action of, the lubricating oil splash on fiber sliver 67, when retaining ring 68 is located at top, the lubricating oil on retaining ring 68 is made in gravity
With lower instillation fiber sliver 67, and then keep lubricant effect more preferable, when convex block 48 and 64 non-contravention of drive block, reset spring 69b
It drives drive block 64 to reset, is not turned on oil filler point 65 with locker room 63, and then effectively prevent lubricating oil from wasting, cleaning set
The use of 49d improves the lubricant effect to hydraulic axis 22, while cooperating drive block 64 is synchronous to use by convex block 48, and then keep away
The waste of lubricating oil is exempted from, the use of lubrication system 6 makes to be lubricated while dedusting, and then convenient for in hydraulic axis 22
Waste residue and its dust are moistened, and then substantially increase dedusting quality, and the hydraulic axis 22 after making dedusting is timely lubricated,
Improve the maintenance quality of hydraulic axis 22.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
