For the adjustment of eccentricity, for example, as shown in fig. 1-2, the vibration exciters 23 are set as four and divided into two groups of opposite angles, and the two groups of opposite angles are used, and the adjustment of the crushing force can be realized by adjusting the included angle between any one group of eccentric angles and the other group of eccentric angles, that is, under the condition of the same rotation speed, when the two groups of opposite angles are in the same direction, the included angle is regarded as 0 ° and the crushing force is the largest; when the two groups of eccentricities are just opposite, the included angle is 180 degrees, and the crushing force is minimum; the two groups of eccentricities can be adjusted at 0-180 degrees to realize the adjustment of the crushing force.
For adjusting the rotating speed, that is, the magnitude of the crushing force is in direct proportion to the square of the angular velocity, the rotating speed can obviously change the magnitude of the crushing force, specifically, the motor 41 is configured as a variable frequency motor, so that the stepless speed regulation of the variable frequency motor is realized through a frequency converter, and the higher the rotating speed is, the larger the crushing force is; the lower the rotation speed, the reverse is true.
Furthermore, the purpose of adjusting under the conditions of different materials, different feeding particle sizes, different required particle sizes and the like can be realized by adjusting the combination of the two variables, so that the application range is expanded, and the market competitiveness of the cone crusher is favorably improved.
It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. The invention is not described in detail in order to avoid unnecessary repetition.
The invention is not limited to the above alternative embodiments, and any other various forms of products can be obtained by anyone in the light of the present invention, but any changes in shape or structure thereof, which fall within the scope of the present invention as defined in the claims, fall within the scope of the present invention.
