Embodiment 1
[0031] As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11 and Fig. 12, the present invention uses a long-ring type piezoelectric vibrator as the exciter The vibration body, the long-ring piezoelectric vibrator is composed of a long-ring metal ring 3 and a piezoelectric ceramic sheet 12, and the long-ring metal ring 3 is composed of upper and lower straight beam segments and two arc segments; The conveying surface of the metal ring 3 can be pasted with friction materials to improve the conveying efficiency; a hopper 7 is installed on the upper part of the long-ring piezoelectric vibrator, and the hopper 7 can evenly output materials to the long-ring piezoelectric vibrator according to the set parameters; The long-ring piezoelectric vibrator is installed on the support rod 2 through the elastic element 1, and the elastic element 1 is made of rubber or other elastic materials; the support rod 2 is installed on the base 5, and the b...
Embodiment 2
[0033] As shown in Figure 13, its structure is the same as that of Embodiment 1, the difference is that two long-ring piezoelectric vibrators are arranged in parallel along the conveying width direction, or a plurality of them can be arranged in parallel along the conveying width direction to increase the Material delivery volume.
