Next, referring to Fig. 5, turn swing ilX! The details 511) of the driving section (8) will be explained below.

This rotating vibration drive unit (8) is composed of an electric motor (morph pulley 126, which is driven once by J2 and fixed to the end of the rotating shaft (25) of the electric motor D*124), a belt (27), and a thick The rotary drive shaft (brown) is driven 11 times through the pulley (28) for 3 rotations 1. The rocking shaft 6G) is the housing (29)
The inner horizontal wall (130) (/'C) is rotatably supported by the upper bearing link (33) fixed to the earthen wall 051 of the fixed lower bearing (3υ and housing t29),
The lower end VC is the big goo! J (28+ is fixed, and a balance way f, 37) whose shape is clearly shown in FIG. 6A is fixed to its upper end (36a,). (321 (3 forces are oil seals.

On the upper surface of the balance weight 137), the outer ring side of the self-aligning bearing (1 part) is fixed so that it is eccentric in the direction opposite to the axis of the drive rotation shaft (gold) and the center of gravity G of the balance weight. 39, and four crank bins (39) are fixed to the inner ring side thereof. Crankbin (39)
On the other hand, as shown in Fig. 3, a nut (1 (1iK, t : The end of the crank bottle (39) is fixed with a thread), and the crank bottle (39) and 5 drive are connected by screwing a nut (4Ql threaded and cotton-plated) to this. It can be integrated with the mounting member (7).

The rotating vibrating sieve device according to the embodiment of the present invention is constructed as described above, and its operation and effects will be explained next.

When the electric motor (2) is driven, the drive rotation shaft (1) rotates,
Along with this, the balance weight 0η is shown in Figures 6A and 6B.
Rotate in the VC4 direction as shown in the figure. The rotating shaft (bearing 138 mounted eccentrically on the balance weight [371VζITsU], that is, the crank pin 69) rotates at a radius δ at one point of the axis of the rotating shaft (3G). As a result, the drive unit mounting member (7) fixed to the crankshaft (39) also undergoes a rotational movement 2 with a radius of δ.As shown in an exaggerated manner in FIG. The sieve screen (4) becomes elliptical,
It performs long elliptical vibration, and almost M-line vibration is performed at the exit end 91. Such so-called swirling vibration itself is well known. When the fine-grained material to be sieved is fed from the material input port (3) to the sieve screen (4), the material is immediately dispersed, and the material to be sieved is passed through the sieve screen (4). The material reaches the screen quickly and can be sieved efficiently.The material under the sieve is discharged to the outside through the discharge port (5), and the material on the sieve is discharged to the outside through the discharge guide (6).

The center of gravity G of the balance weight (37) is the crank bin 6J
are in opposite directions with respect to the axis of the rotating shaft (36), so the whole of the 1st section mounting member (7) is It is in the opposite direction to the inertial force F acting on the inertial force F. Note that j7. and )2 are the balance weights (3θ, Gushin (jlJ, etc.) are set -1 so that they have the same magnitude as X'. As shown in Figure 68 and Figure 6B, the center of the casing (1)
Both in the direction along C-C and in the direction perpendicular to this, the inertia force F1 and the centrifugal force) always cancel each other out, and the base (
9) V? - Although the transmitted vibration force is minimized, the moment of inertia of the center line C-C of the entire device is quite small. Since they always act to cancel each other out, it is best for the casing (Q+) to move stably as described above.In addition, the unbalanced force transmitted to the base (9) is absorbed by the vibration damping force 1.
) It is completely absorbed compared to VC.

In particular, in this example, a coil spring (II l) embedded in the rubber (I a In this way, the movement can be started and stopped stably without performing erratic movement.

In addition, in this embodiment, the casing (1) is supported by the support rod 4 (14) so as to be able to rotate and vibrate, but the structure is simpler than that of the conventional support rod 4 (14), which is supported by a so-called sliding metal. No need for troublesome adjustment work such as centering.
),,fr, There is no need to worry about wear and noise. On the other hand, since the drive unit (8) does not use a heher gear like the conventional one, it is much quieter.
