When impurity volume is larger, though scroll wheel possesses avoidance ability, but after scroll wheel repeatedly scrolls through impurity, rolling
The structures such as driving wheel, perpendicular slide rail are still susceptible to damage.In the present embodiment, if impurity volume is larger, when scroll wheel is through impurity
Afterwards, the distance that scroll wheel, cross bar move right can more (now scroll wheel can make the action of a bounce, i.e., traversing dynamic
Distance can exceed the lateral dimension of impurity, and this is that, as foreign body is larger, the scroll wheel in movement touches impurity quickly, can be straight
Connect and outwards flick, just as the wheel advanced on level land, if ground is suddenly raised larger, when wheel is passed through can it is of short duration from
Ground), now cross bar right-hand member can push triggering piston and move to right, so as to the hydraulic oil pressure of triggering intracavity is pushed up knife chamber to each, so as to
Each top knife piston is driven to move to left, above scroll wheel, the shave hook of lower section is moved to the left, and extend in perpendicular slide rail that (contact is perpendicular
Chute bottom land), during continuing to rise or fall in railing body, (the erecting in chute) on perpendicular slide rail can be wiped off
Impurity.And after triggering piston is moved to right, in the presence of pin spring, alignment pin lower end can be entered in spacing hole, so triggering is lived
Plug will not reset, and shave hook is all the time to carrying out scraping cleaning in perpendicular chute.And until when railing body resets in place, being arranged on matrix
On perpendicular push rod upper end just can enter in spacing hole, so that alignment pin are lifted off spacing hole, finally contact is touched to erect push rod upper end
Send out piston.And after alignment pin have left spacing hole, under action of reset spring, piston reset is triggered, so as to each top knife piston is multiple
Position, shave hook move right and reset.Consequently, it is possible to both be not in that shave hook is scraped inside perpendicular chute and caused fast all the time
Speed abrasion, and automatic detection can be carried out when can ensure and have demand and cleaning is scraped.And scale removal process is completely effectively, and can be in railing
Body ensures that shave hook is isostructural after falling to resetting and automatically resets.
