The right side fixed mounting of mount 13 has fan housing 18, the effectual intake that promotes mount 13, consequently has promoted the dust collection efficiency of this device to a certain extent to the practicality of this device has been promoted.

The front of the fixed frame 13 is fixedly provided with a switch 28, the top end of the fixed base 2 is provided with a first cavity 3, the bottom end of the inner wall of the first cavity 3 is fixedly provided with a first bevel gear 4 through a bearing, the first bevel gear 4 is engaged with a second bevel gear 5, the right side of the second bevel gear 5 is fixedly arranged with the right side of the inner wall of the first cavity 3 through a bearing, the inner side of the second bevel gear 5 is fixedly provided with a rotating shaft 6, the right end of the rotating shaft 6 passes through a through hole on the right side of the fixed base 2 and extends to the outer side of the fixed base 2, the inner part of the first bevel gear 4 is fixedly provided with a screw rod 7, the top end of the screw rod 7 is fixedly connected with the top end of the inner wall of the first cavity 3 through a bearing, the screw rod 7 is sleeved with a lifting platform 8, the bottom end of the, the top of connecting rod 12 all activity extends to the outside of fixing base 2, the top of two connecting rods 12 and the bottom fixed connection of mount 13, it is rotatory at this moment to drive second bevel gear 5 through the handle rotation on holding axis of rotation 6 right side, because second bevel gear 5 and first bevel gear 4 meshing, therefore at this moment first bevel gear 4 atress is rotatory, and then it is rotatory to drive lead screw 7, when lead screw 7 is rotatory, through thread groove 9 screw-thread fit's elevating platform 8 rebound in first cavity 3 on lead screw 7, and then drive connecting rod 12 rebound, thereby make mount 13 rebound, at this moment, the distance grow between mount 13 and the ground, can remove dust to more height departments inside the tunnel through this kind of mode, the effectual practicality that has promoted this device.

All seted up spout 10 in the fixing base 2 of 3 inner wall both sides of first cavity, and spout 10 all is linked together with first cavity 3, the inside slidable mounting that all of spout 10 has slider 11, and the slider 11 one side that is close to each other all with elevating platform 8 fixed connection, because slider 11 and elevating platform 8 fixed connection, consequently when elevating platform 8 reciprocated in first cavity 3, drive slider 11 and slide from top to bottom in spout 10 to stability when having promoted elevating platform 8 and having moved about from top to bottom.

The working principle is as follows: when the staff uses this device, at first transport this device to the tunnel inside through the universal wheel of supporting seat 1 bottom and the left handle of fixing base 2, with this device external power supply, thereby for this device provides electric power support, staff's accessible operating switch 28 starts fan 15 during the use, at this moment fan 15 work rotates, thereby inhale the inside of mount 13 with the near air in fan housing 18 right side, at this moment the inside of dust mixed air formation air current entering mount 13 in the air and the tunnel, when getting into mount 13 inside, dust in the air is blockked by filter screen 17 and is filtered, the air after the filtration passes filter screen 17 and wind hole 14 and discharges from protection storehouse 16 bottom, thereby remove dust to the tunnel inside.

When the fan 15 is turned off, dust on the filter screen 17 adsorbed by wind power and attached to the filter screen 17 falls downwards due to attraction, and then passes through the feed port 19 to enter the interior of the collection box 20, when a certain amount of dust is collected in the collection box 20, the pull plate 27 is held and shifted rightwards, at this time, the pull plate 27 drives the limiting insert block 25 to extrude the compression spring 24 and move inwards, when the limiting insert block 25 moves inwards to a certain position, the limiting insert block 25 is not connected with the connecting groove 26 for limiting, at this time, the insert plate 21 is not connected with the slot 22 for limiting, further, the collection box 20 is not connected with the fixed frame 13 for limiting, at this time, the collection box 20 can be detached from the fixed frame 13, and therefore the dust in the collection box 20 can be treated.

The handle on the right side of the rotating shaft 6 is held to rotate, the rotating shaft 6 drives the second bevel gear 5 to rotate at the moment, the second bevel gear 5 is meshed with the first bevel gear 4, the first bevel gear 4 is stressed to rotate at the moment, the screw rod 7 is driven to rotate, when the screw rod 7 rotates, the lifting platform 8 which is matched with the screw thread through the thread groove 9 on the screw rod 7 moves upwards in the first cavity 3, the connecting rod 12 is driven to move upwards, the fixing frame 13 moves upwards, the distance between the fixing frame 13 and the ground is increased at the moment, the handle on the right side of the rotating shaft 6 stops rotating after the proper height is adjusted, and then the dust removal work can be.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
