Description
Technical field
The invention belongs to cleaners, environmental technology field, and more specifically, in particular to the dedusting without device of cranking arm is taken out
Inhale arm configuration.
Background technique
It is that this sweep-up pipe for needing dust catcher of electric welding processing carries out dust suction work for a long time by it in industrial processes place
Place, for convenience absorb weldering cigarette, can generally select band aspirate arm (air suction arm) industrial dust collector.
Based on above-mentioned, the inventors discovered that, existing suction arm (air suction arm) structure design is more unreasonable, generally by song
Arm and sweep-up pipe are constituted, and crank arm and the inside of sweep-up pipe is arranged in, which exists following insufficient: 1., which crank arm, occupies sky in sweep-up pipe
Between, influence pick-up performance；2. the weldering cigarette of inspiration, dust etc. are fallen in crank arm on, easily blocking is cranked arm joint, keeps the activity of cranking arm ineffective
Setting card plug living, seriously affects using effect, shortens service life；3. aspirating arm (air suction arm) activity point of view via cranking arm
Limit, its own can not 360 ° arbitrarily rotate freely, cannot satisfy the use demand.
Summary of the invention
In order to solve the above technical problem, the present invention provides the dedustings without device of cranking arm to aspirate arm configuration, to solve to crank arm
Space in sweep-up pipe is occupied, pick-up performance is influenced；The weldering cigarette of inspiration, dust etc. are fallen in crank arm on, easily blocking is cranked arm joint, is made
The not flexible setting card plug of activity of cranking arm, seriously affects using effect, shortens service life；Aspirate arm (air suction arm) activity point of view
It is limited via cranking arm, its own can not 360 ° of the problem of arbitrarily rotating freely, cannot satisfying the use demand.
The purpose and effect of dedusting suction arm configuration of the present invention without device of cranking arm, are reached by technological means in detail below
At:
