[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Reference Figure 1-5 The angle-adjustable ultrasonic vibrating screen shown in the figure comprises a base 1, a mounting base 2, and a screen body 3. The base 1 is connected to the mounting base 2 via a spring. The top of the mounting base 2 is also connected to the screen body 3 for screening materials. The mounting base 2 is also connected to an exciter 4 for driving its vibration.

[0025] The output shaft 41 of the exciter 4 is connected to the eccentric mass 5 through a connecting assembly 6. The output shaft 41 is provided with two groups and is symmetrically arranged at the upper and lower ends of the exciter 4. A through hole 51 is provided on the eccentric mass 5, and the output shaft 41 is connected to the eccentric mass 5 through the through hole 51.

[0026] Under the action of the connecting assembly 6, the angle between the two groups of eccentric blocks 5 can be adjusted.

[0027] The connecting assembly 6 includes an adjusting bolt 61 and an adjusting block 66. The eccentric block 5 is also provided with a slide groove 67 connected to the through hole 51. The adjusting block 66 is slidably connected in the slide groove 67. The adjusting block 66 is an arc-shaped block. The adjusting block 66 adjusts its position relationship in the slide groove 67 through the adjusting bolt 61. The eccentric block 5 is provided with a threaded hole engaged with the adjusting bolt 61. The threaded hole is connected to the slide groove 67. One end of the adjusting bolt 61 passes through the threaded hole and is rotatably connected to the adjusting block 66. When the adjusting bolt 61 rotates, it will only drive the adjusting block 66 to slide in the slide groove 67 and cannot drive the adjusting block 66 to rotate.

[0028] The adjusting block 66 and the output shaft 41 are provided with teeth on their facing surfaces. The output shaft 41 is provided with tooth grooves 43 meshing with the teeth. The angle between the two sets of eccentric blocks 5 is adjusted by the meshing relationship between the teeth and the tooth grooves 43.

[0029] A protrusion 42 is provided at the end of the output shaft 41 away from the exciter 4, and the protrusion 42 is connected to the end plate 62 by a connecting bolt 63. A sliding sleeve 64 is also slidably connected to the output shaft 41. The sliding sleeve 64 limits the eccentric block 5 under the limitation of the limiting bolt 65. The end plate 62 and the sliding sleeve 64 are used in conjunction to limit the eccentric block 5, preventing the eccentric block 5 from sliding along the output shaft 41, and will not affect the rotation of the eccentric block 5 around the output shaft 41.

[0030] The end plate 62 is also provided with a groove 68 that is adapted to the size of the protrusion 42. The side wall of the end plate 62 is also provided with scale lines, and the eccentric block 5 is provided with indicator lines corresponding to the scale lines. The cooperation between the protrusion 42 and the groove 68 is to make the scale lines and the indicator lines correspond to each other, thereby ensuring the installation position and accuracy of the end plate 62.

[0031] The working principle of the utility model is as follows: when in use, according to the characteristics of the material to be screened, the angle between the two sets of eccentric wheels is adjusted so that the equipment can better screen the material; the staff rotates the adjusting bolt 61 counterclockwise, and the adjusting bolt 61 engages with the threaded hole on the eccentric weight 5, so that the adjusting bolt 61 drives the adjusting block 66 to slide in the slide groove 67, and the end of the adjusting bolt 61 is rotatably connected to the adjusting block 66 without affecting the rotation of the adjusting bolt 61, so that the adjusting block 66 is away from the output shaft 41, and the teeth on the adjusting block 66 slide out from the tooth groove 43 on the output shaft 41, releasing the limit between the eccentric weight 5 and the output shaft 41, and the eccentric weight 5 can be rotated. The eccentric weight 5 rotates around the output shaft 41 and is slidably connected with the sliding sleeve 64 and the end plate 62, so as to adjust the angle between the two sets of eccentric weights 5. After the adjustment is completed, the adjusting bolt 61 is rotated clockwise to drive the adjusting block 66 to return to its original position, completing the limit of the eccentric weight 5 to adapt to the screening of different materials.
