Currently, the exciting source in vibrating feed (screening) equipment that the industries such as coal in China, metallurgical mine use, a kind of
It is vibrating motor (electric activator or vibration source three-phase abynchronous motor), another kind is driven by ordinary motor with bias
The vibrator of mechanism.The vibration excitor vibration force of both forms all cannot in equipment running process its size of on-line tuning, all
Under shutdown status, the coincidence angle of vibrating motor eccentric block or the eccentric block quality of eccentric stiffener vibrator big must be adjusted
It is small, to change the size of exciting force.Now, coal in China, metallurgical mine vibratory equipment in, it is accordingly required in particular to it is a kind of to run
The size for easily changing exciting force in the process, thus the vibration excitor of on-line tuning production capacity size.
Summary of the invention
To adapt to the shortcomings that mine needs, overcomes current various vibration excitors, the purpose of the utility model is to provide a kind of energy
Change the size of exciting force, easily in equipment running process so as to adjust the online acceleration variable force exciting of production capacity
Device.
To achieve the above object, the technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of add online
Fast variable force vibration excitor, is made of slide block device, fixed eccentric block, motor, key and shield, in special double output shaft motors
Both ends pass through key respectively and are equipped with fixed eccentric block, are provided with slide block device outside fixed eccentric block, slide block device it is outer
Face shaft end is fixed with circlip for shaft, and there are certain intervals between fixed eccentric block and slide block device, makes the cunning of slide block device
Block can be slided up and down freely, and shield is connected with the both ends of motor.
The online acceleration variable force vibration excitor of above structure, slide block device is by screw, spring bearer plate, spring, limit plate, cunning
Block, lead adjustment block and slideway composition, two springs are separately positioned in the hole of limit plate, are provided with spring bearer plate above, are led to
Cross screw spring bearer plate, spring, limited block and sliding block are fixed together, by adjusting between spring bearer plate and limited block away from
From H, the distance of glide of sliding block can be changed, H is bigger, and sliding block is remoter apart from the center of circle in operation, and exciting force is bigger；Two slideways point
The both sides of sliding block are not set, and are linked together by screw and fixed eccentric block, the boss and slideway groove kissing of sliding block
It closes, sliding block can be free to slide in slideway；Lead adjustment block is the different muti-piece composition of thickness, according to the big of required exciting force
It is small, it determines the quantity of lead adjustment block, is fixed by screw and sliding block.
The utility model has following features compared with prior art using the above structure.
1, the utility model is to axle center according to the size of exciting force and the quality of sliding block and sliding block center of gravity apart from directly proportional
Relationship and design, the quality of sliding block is bigger, sliding block center of gravity to axle center distance it is remoter, exciting force is bigger.The utility model skill
Art is exactly that exciting force is increased or reduced in motor operation course, and motor is in compared with slow-speed of revolution operational process, and sliding block is in bullet
Under spring pulling force effect, not slide downward, the exciting force of generation is smaller, when need it is online increase exciting force when, increased by frequency conversion
The revolving speed of big motor, sliding block overcome spring tension to move out, and sliding block center of gravity to axle center distance increases, and exciting force increases online
Greatly.If necessary to increase exciting force during exercise, the vibrating motor of the prior art is irrealizable, it is necessary in shutdown status
Under, increase the registration of eccentric block, increases exciting force.
2, the utility model according to requirements, there is the size that exciting force can also be adjusted at two: one is adjustment spring
The distance of glide of sliding block can be changed in the distance between pressing plate and limited block H, and H is bigger, and sliding block is remoter apart from the center of circle in operation,
Exciting force is bigger；The second is the density due to lead is bigger, the quantity of lead adjustment block is changed, the size of exciting force also can be changed.
3, the utility model is a big innovation of vibration excitor design aspect, has filled up domestic online acceleration variable force vibration excitor side
The blank in face.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model accelerates variable force vibration excitor online.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
In figure: 1.5 sliding block of 1- slide block device 1.1- screw 1.2- spring bearer plate 1.3 spring, 1.4 limit plate, 1.6 lead
Adjustment block 1.7- slideway 2- fixed eccentric block 3- key 4- motor 5- shield.
Specific embodiment
Comparative diagram 1~2, the utility model accelerate variable force vibration excitor online, by slide block device, fixed eccentric block, motor,
