Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be known from figures 1 to 5, the utility model discloses an inner diameter is greater than impeller apron diameter and with the first drum 1 of impeller apron coaxial arrangement, the outside cover of first drum 1 is equipped with one with the coaxial and interval arrangement's of first drum 1 second drum 2, the lower extreme fixed connection of first drum 1 and second drum 2, the section of thick bamboo wall upper end circumference equipartition of first drum 1 has multiunit and blade one-to-one's gear 3, the outside meshing of a plurality of gears 3 has an inner gear ring 4 of slidable mounting on second drum 2, the coaxial fixed with a telescopic link 5 of the lower extreme of every gear 3, the free end demountable installation of telescopic link 5 has a steel wire ball 6 of arranging in double-phase adjacent blade gap in, every telescopic link 5 goes up the cover and is equipped with an extension spring 7 that makes it have the shrink trend, the coaxial fixed with a bull stick 8 in the second drum 2.

In order to realize the detachable installation of the steel wire ball 6, the free end of each telescopic rod 5 is fixed with a steel wire ball 6 installation seat 9, the steel wire ball 6 is detachably installed on the installation seat 9 through a bolt, one end of the tension spring 7 is fixed on the rotating shaft of the corresponding gear 3, and the other end of the tension spring is fixed on the installation seat 9.

In order to realize the fixation and the driving of the rotating rod 8, the upper end of the second cylinder 2 is fixed with a cross rod 10, the rotating rod 8 penetrates through the cross rod 10 and can rotate on the cross rod 10, the upper end of the rotating rod 8 is provided with a shifting rod 11, the lower end of the rotating rod 8 is provided with a chuck 12 capable of being inserted into an impeller shaft hole, and the impeller is driven to rotate through the matching of the chuck 12 and the shaft hole.

The utility model discloses a concrete working process is: this device will treat the impeller of rust cleaning and arrange in a plane when using, make the blade up, with this device lock on the impeller, make the impeller arrange in first drum 1, keep every steel wire ball 6 to correspond respectively and install in the gap that forms rather than two adjacent blades of one-to-one this moment, and insert chuck 12 with driving lever 11 lower extreme in the shaft hole on the impeller apron, and carry out spacingly to chuck 12 through the keyway in the shaft hole, the blade height will be less than the height of telescopic link 5 this moment.

Keeping the second cylinder 2 fixed, driving the rotating rod 8 to rotate the impeller in a reciprocating manner through the chuck 12 by rotating the rotating rod 8 in a reciprocating manner, extruding the blades and driving the steel wire ball 6 to move in a reciprocating manner in a gap formed by the two blades by the reciprocating rotation of the impeller, polishing the surfaces of the blades and the bottom of the gap formed by the two blades by the steel wire ball 6 by the movement, thereby realizing the rust removal of the impeller, the telescopic rod 5 can extend under the extrusion of the blades in the reciprocating movement process, the tension spring 7 is stretched in the extension process of the telescopic rod 5 and has the rebound tendency and the elastic potential energy, the telescopic rod 5 can also swing while rotating the impeller, the swing of the telescopic rod 5 drives the gear 3 to rotate, the outer sides of the gears 3 are jointly meshed with an inner gear ring 4, under the action of the inner gear ring 4, the synchronous rotation of each gear 3 is ensured, so that the synchronous swing of the telescopic rod 5 is realized.

The significant benefits of the present device: this device is to the in-process of impeller lock, can have steel wire ball 6 not to arrange the condition in two blade gaps in, need manual movement telescopic link 5 this moment to make steel wire ball 6 arrange two blade gaps in, a plurality of gears 3 that are engaged with simultaneously by an inner gear ring 4 can realize the synchronous rotation of a plurality of gears 3 when rotating one of them gear 3, thereby satisfy and arrange a plurality of steel wire balls 6 in corresponding gap in step fast, thereby realize simple to operate, for the rotation of impeller, the impeller lower extreme can set up the rotation, steel wire ball 6 is flexible deformable simultaneously, therefore steel wire ball 6 can fully polish the blade when removing in two blade gaps and make the rust cleaning more abundant thoroughly.
