Exhibition serves irreplaceable effect.But during the work of major part vibrating machine shaken with certain amplitude and frequency at present
Dynamic, it has not been convenient to be adjusted, which has limited application of the vibrating machine in the operating mode that many amplitudes and frequency change.
Utility model content
To solve the above problems, the utility model provide it is a kind of can be with adjusting amplitude and the vibrating device of frequency, can be with
The need for meeting more vibration working environments, the application of vibrating machine is further expanded.
In order to realize the purpose, the utility model is adopted the following technical scheme that：A kind of vibration dress of amplitude and frequency-adjustable
Put, including linkage and driving element, the linkage is made up of crank, connecting rod, rocking bar and vibrating arm, passing through hinge will
It is connected, and has a notch on the connecting rod, and the roller of crank end can be freely rolled crank-guide way is intraoral, the driving member
Part is made up of hydraulic cylinder and motor, and the hydraulic cylinder bottom is fastened on base by flange, and top passes through spiral shell with motor
Bolt is connected, and is formed a fixed connection between the motor and crank, can make vibration by the cycle movement of drivening rod mechanism
Bar up-and-down movement.
Further, the hinged connecting shaft diameter of axle is identical with connected piece aperture, during connection on the inside of connected piece
The connecting shaft shaft shoulder is close in face, and lateral surface is close to the circlip for shaft for connecting shaft end, it is ensured that connected piece can only be around connecting shaft
Rotate.
Further, the external diameter of the roller is identical with connecting rod width of rebate, it is ensured that roller is close to notch rolling.
Further, being vibrated outside the vibrating arm provided with one on rod bearing, the flat board on its top has an internal diameter and vibrating arm
External diameter identical through hole, vibrating arm is passed through from through hole, vibrating arm is movable in a vertical direction.
After technical scheme described in the utility model, following beneficial effect is brought：
The vibrating device of a kind of amplitude and frequency-adjustable described in the utility model, can change motor by hydraulic-driven
Upright position and then the amplitude for changing vibrating arm, can also realize the adjustment of vibration frequency by the rotating speed of regulation motor, meet
The need for more vibration operating modes.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
As shown in figure 1, the vibrating device of a kind of amplitude and frequency-adjustable, including linkage and driving element, the company
Linkage is made up of crank 5, connecting rod 7, rocking bar 11 and vibrating arm 9, is connected by hinge, has one on the connecting rod 7
Notch, the roller 6 of the end of crank 5 can freely be rolled in the notch of connecting rod 7, and the driving element is by 4 groups of hydraulic cylinder 2 and motor
Into the bottom of hydraulic cylinder 2 is fastened on base 1 by flange, and top is bolted fixation with motor 4, described
Formed a fixed connection between motor 4 and crank 5, the vertically reciprocating fortune of vibrating arm 9 can be made by the cycle movement of drivening rod mechanism
It is dynamic.
With reference to shown in Fig. 1 and Fig. 2, all revolute pairs are connected through the hinge in device, the hinged diameter of axle of connecting shaft 12
Identical with connected piece aperture, connected piece medial surface is close to the shaft shoulder of connecting shaft 12 during connection, and lateral surface is close to the end of connecting shaft 12
The circlip for shaft 13 in portion, it is ensured that connected piece can only be rotated around connecting shaft.
With reference to shown in Fig. 1 and Fig. 3, the external diameter of the roller 6 is identical with the width of rebate of connecting rod 7, and roller 6 can be close to during motion
Notch is rolled, and is solely subjected to force of rolling friction, it is possible to reduce the abrasion of part and the consumption of the energy.
As shown in figure 1, the outside of vibrating arm 9 is vibrated on rod bearing 8, the flat board on its top provided with one has an internal diameter with shaking
The external diameter identical through hole of lever 9, vibrating arm 9 is passed through from through hole, vibrating arm 9 is movable in a vertical direction.
As shown in figure 4, the initial position of motor 4 can be adjusted by changing the extension elongation of hydraulic cylinder 2, and then it can adjust and shake
The amplitude of lever 9, the vibration frequency of vibrating arm 9 is identical with the rotating speed of motor 4, therefore can be real by changing the rotating speed of motor 4
The adjustment of existing vibration frequency, the need for meeting different operating modes.
It the foregoing is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of this area
