Abstract
The utility model discloses a two eccentric formula vibrating device of prickly ash sieve separator symmetry, including symmetrical eccentric formula transmission shaft, the symmetrical eccentric formula transmission shaft of installation on the prickly ash sieve separator, symmetrical eccentric formula transmission shaft pass through the bearing frame and link to each other with prickly ash sieve separator frame, symmetrical eccentric formula transmission shaft through last reel jointed connecting rod, round pin axle, go up fixed cover and link to each other with the combination of last reel, symmetrical eccentric formula transmission shaft through reel jointed connecting rod down, round pin axle, down fixed cover and down the reel combination link to each other, two eccentric shafts are the symmetries for the transmission shaft central line on the eccentric formula transmission shaft of symmetry, the eccentric formula transmission shaft of symmetry drives through the belt pulley to carry out rotary motion, the eccentric formula transmission shaft of symmetry is through last reel jointed connecting rod, round pin axle, goes up fixed cover and link to each other with the combination of last reel, the eccentric formula transmission shaft of symmetry be through lower reel jointed connecting rod, round pin axle, down fixed cover and down the reel combination link to each other. Eccentric transmission shaft drives reel combination carrying on horizontal reciprocating motion respectively through connecting rod, round pin axle, fixed cover when being rotatory. Because two eccentric pillow blocks are symmetrical for the transmission shaft central line on the transmission shaft, therefore the horizontal reciprocating motion who goes up reel combination and reel combination down is opposite, and to whole equipment, its internal action power cancel each other out so equipment is whole operates steadily, has eliminated the phenomenon of the violent shake of equipment. Again owing to two eccentric pillow blocks on the transmission shaft design for transmission shaft center line symmetry for the horizontal atress of transmission shaft also is cancel each other out, therefore has improved transmission shaft life.
Description
Technical field
The utility model relates to the one machinery of processing of farm products, a critical component in Chinese prickly ash screening machine, and a kind of symmetric double Link-Belt PD device relate to Chinese prickly ash screening machine performance quality, determines the height of Chinese prickly ash screening quality.
Background technology
Generally all need to carry out pulverizing, screening through the Chinese prickly ash of drying after harvesting, the impurity such as green pepper seed, green pepper stalk, green pepper leaf in Chinese prickly ash are cleaned out, improve the product hierarchy of Chinese prickly ash.
At present, the screening of Chinese prickly ash generally adopts artificial screening and screen frame single movement formula mechanical grading.
Artificial screening is screened Chinese prickly ash by push-and-pull screen frame before and after manpower, and Chinese prickly ash screening will totally need multiple working procedure progressively to complete by this mode, consumes a large amount of manpower, inefficiency.
Screen frame single movement formula mechanical grading, pull multilayer screen frame to be combined into the screening of row Chinese prickly ash with motor-driven single eccentric shaft, although this mode screening effeciency improves, but because multilayer screen frame Combination Welding is overall, when eccentric shaft pulls screen frame, mechanical oscillation are very large, eccentric shaft discontinuity, easy fracture, equipment fluctuation of service, noise is large.
Summary of the invention
The purpose of this utility model is to provide a kind of reliable and stable, symmetric double Link-Belt PD device of operating steadily.Use this device, Chinese prickly ash screening machine runs very steady, and noise is low, eccentric shaft uniform force, and impulsive force is little, occurs without phenomenon of rupture.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Chinese prickly ash screening machine symmetric double Link-Belt PD device, comprise symmetrical centering type power transmission shaft, it is characterized in that: Chinese prickly ash screening machine is installed symmetrical centering type power transmission shaft, symmetrical centering type power transmission shaft is connected with Chinese prickly ash screening machine frame by bearing block, symmetrical centering type power transmission shaft is combined with upper screen frame be connected by upper screen frame jointed connecting rod, bearing pin, upper fixed cover, and symmetrical centering type power transmission shaft is combined with lower screen frame be connected by lower screen frame jointed connecting rod, bearing pin, lower fixed cover.
According to described Chinese prickly ash screening machine symmetric double Link-Belt PD device, it is characterized in that: on symmetrical centering type power transmission shaft, two eccentric shafts are symmetrical relative to center transmission shaft line.
According to described Chinese prickly ash screening machine symmetric double Link-Belt PD device, it is characterized in that: symmetrical centering type power transmission shaft is driven by belt pulley and is rotated.
According to described Chinese prickly ash screening machine symmetric double Link-Belt PD device, it is characterized in that: symmetrical centering type power transmission shaft to be combined with upper screen frame by upper screen frame jointed connecting rod, bearing pin, upper fixed cover and (is connected.
According to described Chinese prickly ash screening machine symmetric double Link-Belt PD device, it is characterized in that: symmetrical centering type power transmission shaft to be combined with lower screen frame by lower screen frame jointed connecting rod, bearing pin, lower fixed cover and is connected.
The utility model has the advantages of and be: this vibrating device have employed symmetrical centering type power transmission shaft, drive screen frame to combine respectively by connecting rod, bearing pin, fixed cover when eccentric drive shaft rotates and carry out horizontal reciprocating movement.Because two eccentric pillow blocks on power transmission shaft are symmetrical relative to center transmission shaft line, thus it is contrary for going up the horizontal reciprocating movement that screen frame combination combines with lower screen frame, for whole equipment, its inertial forces is cancelled out each other, so Whole Equipment operates steadily, the phenomenon that the equipment that eliminates acutely is shaken.Again because two eccentric pillow blocks on power transmission shaft are relative to center transmission shaft line symmetric design, such that power transmission shaft is lateral stressed also cancels out each other, thus improve power transmission shaft service life.
