[0025] Among them, one end of the floating screen frame 4 is provided with a first connecting member 13. There are two first connecting members 13 in total, and the first connecting members 13 are arranged on both sides of the screen frame 1.

[0026] Among them, the third vibration assembly includes a vibration beam 10 and a second vibration motor 11.

[0027] Among them, the screen 3 is connected to the vibration beam 10 through a second connecting member 14.

[0028] Among them, the second vibration motor 11 is a two-stage vibration motor.

[0029] A three-mass energy-saving high-frequency vibrating screen and its method, applied to the described three-mass energy-saving high-frequency vibrating screen, includes; Driven by two groups of first vibration motors 2, the screen frame 1 makes a simple harmonic linear vibration at 45 degrees under the support of the rubber support springs 6, so that the materials put into the screen frame 1 can move forward quickly on the screen 3, realizing the layering and separation of the input material particles; The specific process of the screen frame 1 making a simple harmonic linear vibration at 45 degrees is as follows: During the working process, two groups of first vibration motors 2 are started simultaneously, but the rotation directions of the shafts of the two groups of first vibration motors 2 are opposite; the flywheel 21 with eccentric mass on the half shaft of the first vibration motor 2 generates a centrifugal force F during high-speed rotation. Due to the opposite rotation directions, through the superposition and cancellation of two groups of centrifugal forces F in opposite directions, finally, under the force coupling effect, an effect of a force at 45 degrees to the horizontal is formed, driving the screen frame 1 and the rubber support springs 6 to vibrate on the support 7, so that the screen frame 1 makes a simple harmonic linear vibration at 45 degrees, enabling the materials put into the screen frame 1 to move forward quickly on the screen 3, screening the input materials, realizing the layering and separation of the material particles, and achieving the effects of material conveying and passing through the screen; Driven by the first vibration motor 2, the floating screen frame 4 makes a back-and-forth swinging motion under the support of the first shear spring 8. The purpose of this motion is to imitate manual hand shaking screening, so that the qualified particles in the materials can smoothly pass through the screen 3 and do not get lost with the material flow; The specific process of the floating screen frame 4 making a back-and-forth swinging motion is as follows: Driven by the first vibration motor 2, the floating screen frame 4 and the first shear spring 8 move back and forth in the fixed plate 12, and the floating screen frame 4 drives the screen 3 to make a back-and-forth swinging motion. The purpose of this motion is to imitate manual hand shaking screening. Manual hand shaking screening can achieve the maximum screening efficiency, greatly improving the passing rate of the materials moving forward on the screen 3, enabling the qualified particles in the materials to smoothly pass through the screen 3 and not get lost with the material flow; Driven by the second vibration motor 11, the vibrating beam 10 makes an up-and-down beating motion on the screen 3 through the support of the second shear spring 9, making it difficult for the materials moving forward on the screen 3 to block the screen holes of the screen 3 and reducing the blockage rate of the screen holes; The specific process of making an up-and-down beating motion on the screen 3 through the support of the second shear spring 9 is as follows: Driven by the secondary vibration motor, the vibrating beam 10 and the second connecting member 14 move up and down, and the second connecting member 14 makes an up-and-down beating motion on the screen 3. Since this beating motion has a high frequency and a low amplitude, it has unique advantages for screening fine-grained materials. At the same time, through the high-frequency beating of the screen 3, it is difficult for the materials moving forward on the screen 3 to block the screen holes of the screen 3, reducing the blockage rate of the screen holes, realizing the function of cleaning the screen, improving the screening performance of the equipment, and having a good screening effect especially for materials with a higher moisture content.
