The methods of generating vibration generally include piezoelectric ceramics, electromagnetic and other methods, but the relatively complex structure requires many parts and a supporting power supply to realize.

Contents of the invention

In order to overcome the disadvantages of the complex structure of the vibrating device for tiny particle objects in the prior art, the utility model provides a mechanical vibrating device capable of vibrating tiny particle objects.

The technical scheme that the utility model solves its technical problem adopts is:

The mechanical vibrating device of the present utility model is characterized in that the mechanical vibrating device includes gears, vibrating rods, brackets, central shafts, and vibrating discs, wherein the bracket is L-shaped, and the two ends of the bracket are respectively opened with Hole I, through hole II. The vibrating rod is a stepped shaft structure consisting of a large end of the stepped shaft and a small end of the stepped shaft. The connection relationship is that the central shaft passes through the center hole of the gear and is fixedly connected with the gear, the large end of the stepped shaft of the vibrating rod passes through the through hole I at one end of the bracket, and is slidably connected with the bracket, and the small end of the stepped shaft of the vibrating rod Contact with the outer edge tooth surface of the gear. A spring is arranged between the vibrating rod and the support, and the spring is sleeved on the outer ring of the large end of the stepped shaft of the vibrating rod, and the spring is used for the vibrating rod to be tightly pressed on the surface of the gear. The central shaft passes through the through hole II at the other end of the support and is slidably connected with the support, and the top of the central shaft is fixedly connected with the vibrating plate.

The vibrating rod and the gear are arranged in the same plane.

The diameter of the spring is larger than the diameter of the through hole I.

The central axis is set to match the diameter of the through hole II.

In the utility model, the device is vibrated under the action of the elastic force of the spring to realize vibration and tumbling of tiny particle objects.

The application process of the utility model is as follows: put tiny particles into the vibrating plate, and when the central axis rotates, the gears are also rotated at the same time. Since the vibrating rod is tightly pressed on the surface of the gear, when the gear rotates, the concave and convex surface of the gear will cause the vibrating rod to vibrate. , the vibration of the vibrating rod is transmitted to the vibrating plate through the bracket and the central axis, so that the tiny particles in the vibrating plate can be vibrated.

The beneficial effect of the utility model is that the tiny particle objects can be vibrated. The utility model has the advantages of simple structure, convenient operation and good use effect.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Example 1

FIG. 1 is a schematic structural view of the mechanical vibration device of the present invention, and FIG. 2 is a top view of the mechanical vibration device of the present invention. In Fig. 1, 2, the mechanical vibrating device of the present utility model comprises gear 1, vibrating bar 2, support 4, central shaft 5, vibrating disc 6, wherein, described support 4 is L-shaped, and the two ends of support 4 are respectively There are through holes I7 and through holes II. The vibrating rod 2 is a stepped shaft structure consisting of a large end of the stepped shaft and a small end of the stepped shaft. The connection relationship is that the central shaft 5 passes through the central hole of the gear 1 and is fixedly connected with the gear 1, and the large end of the step shaft of the vibrating rod 2 passes through the through hole I7 at one end of the bracket 4, and is slidably connected with the bracket 4, vibrating The small end of the stepped shaft of the rod 2 is in contact with the outer edge tooth surface of the gear 1 . A spring 3 is arranged between the vibrating rod 2 and the support 4, and the spring 3 is sleeved on the outer ring of the large end of the stepped shaft of the vibrating rod 2, and the spring 3 is used for the vibrating rod 2 to be tightly pressed on the surface of the gear 1. The central shaft 5 passes through the through hole II at the other end of the support 4 and is slidably connected with the support 4 , and the top of the central shaft 5 is fixedly connected with the vibrating plate 6 .

The vibrating rod 2 and the gear 1 are arranged in the same plane.

The diameter of the spring 3 is larger than the diameter of the through hole I7.

The central axis 5 is arranged to match the diameter of the through hole II.

The application process of the utility model is as follows: put tiny particles into the vibrating plate 6, and when the central shaft 5 rotates, the gear 1 is also rotated at the same time. Since the vibrating rod 2 is pressed tightly on the surface of the gear 1, when the gear 1 rotates, the gear 1 rotates The concave-convex surface makes the vibrating rod 2 vibrate, and the vibration of the vibrating rod 2 is transmitted to the vibrating plate 6 through the bracket 4 and the central shaft 5, so that the tiny particles in the vibrating plate 6 can be vibrated, and the number of teeth of the gear 1 can be adjusted. To change the frequency of vibration, the intensity of vibration can be changed by adjusting the compression of spring 3 .
