Abstract
The utility model relates to a dedusting device, in particular to an interval reversing groove wheel mechanism used for a single suction type dedusting unit, and belongs to the technical field of dedusting equipment. The interval reversing groove wheel mechanism comprises a groove wheel (1) and a crank wheel (2) which are matched with each other. A limiting wheel (2.1) and a driving lever (2.2) are arranged on the crank wheel (2). The excircle of the groove wheel (1) is in step shape. The small circle radius R of the groove wheel (1) maintains unchanged. The big circle radius of the groove wheel (1) is enlarged to be equal to the center distance a of the crank wheel (2).
Description
Technical field
The utility model relates to a kind of dusting apparatus, especially relates to a kind of gap reversing groove wheel mechanism for single-suction dedusting unit, belongs to the dusting apparatus technical field.
Background technique
Gap reversing groove wheel mechanism in the single-suction dedusting unit is mainly used in realizing the gap commutation of suction inlet, the sheave clearance mechanism is in design, as crankwheel centre distance a, when groove is counted Z and is determined, sheave external diameter R is fixed value, limited wheel on the crankwheel and driving lever gap pass in and out arc groove and the U-shaped groove of sheave in turn, when limited wheel is about to throw off the arc groove of sheave, driving lever not yet enters U-shaped groove, this moment, there were the free zone in crankwheel and sheave mutual alignment, vibrations during the equipment operation, very easily occur the U-shaped notch mechanical interference of crankwheel driving lever and sheave under the causations such as the imbalance of driving mechanism, then cause the faults such as crankwheel fracture.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of gap reversing groove wheel mechanism is provided, and it has prolonged the guide section of the U-shaped groove of sheave, has eliminated the free zone that crankwheel and sheave mutual alignment exist, and has avoided the hidden danger of mechanical interference.
The purpose of this utility model is achieved in that a kind of gap reversing groove wheel mechanism, be characterized in: it comprises sheave and the crankwheel that cooperatively interacts, be provided with limited wheel and driving lever on the described crankwheel, described sheave cylindrical is step-like, the roundlet radius R of described sheave remains unchanged, and the large circle radius of described sheave increases to the centre distance a of crankwheel.
Compared with prior art, the utlity model has following beneficial effect:
A kind of gap of the utility model reversing groove wheel mechanism, its sheave cylindrical is designed to step-like, the roundlet external diameter keeps R constant, limited wheel on the crankwheel is not interfered when sheave turns round, large circle radius increases to a, prolong the guide section of U-shaped groove, eliminated the mutually free zone of position existence of crankwheel and sheave, avoided mechanical interference hidden danger.
