Vertically shaking working device

A vertically oscillating working device which has a body to be oscillated comprising:

• an inner space that is formed by a cover member and a body to be worked, and receives working materials in it,
• an oscillating means for vertically oscillating the body to be oscillated, and which works the body to be worked by colliding the working materials with the body by oscillation, the oscillating means has an oscillating mechanism having a prime mover, a revolving shaft connected to the prime mover, a crank provided at the revolving shaft, an oscillating plate connected with the crank through a connecting rod, and two or more linear motion guides which are fitted to the oscillating plate and vertically reciprocate the oscillating plate, and the rotary motion given by the prime mover is converted to vertical motion by the crank provided at the revolving shaft, and the oscillating plate connected with the crank reciprocates vertically along the linear motion guide, thereby to vertically oscillate the body to be oscillated fixed at the oscillating plate, and
• an air spring being provided between the oscillating mechanism and a floor on which the oscillating mechanism is placed.
