[Prior art and its problems] Japanese Patent Application Laid-Open No. 2-99174 discloses a method in which a trough on which a sieve net is stretched is vibrated to transfer a material on the sieve net. A plurality of sieve mesh vibration drive units that apply vibration force to rod-shaped members extending in the vertical direction are attached to a mounting plate that is stretched across both edges of the trough and fixed. The lower end of the rod-shaped member is fixed to a sieve net, and when the drive unit is driven, the rod-shaped member vibrates in its axial direction, vibrating the sieve attached to its lower end, and causing the sieve to pass through the sieve. The sieving part of the above material improves efficiency, but when replacing the sieve screen with a new one, not only the mounting plate but also the rod-shaped member of the sieve screen vibration drive unit fixed to this is required. The bolts, etc. that are used to fix the lower end of the screen and the sieve screen must be removed. What is the drive part for sieve mesh vibration? ! Since there are several screens, all of them must be removed and the sieve screen must be replaced with a new one, but as mentioned above, this replacement work is extremely troublesome.

In Fig. 1, when the pair of vibrating motors (8a) and (8b) are energized, the unbalanced weights rotate synchronously, as is well known, and the combined linear vibration force of these forces causes the trough to move in the direction shown by arrow a. Vibrates in a straight line. In addition, each sieve mesh vibration drive unit (
12) is also energized. In Figure 1, the sieve material is transferred from the hopper (13) to the electromagnetic vibration feeder (1
4) through the sieve material feed opening (6) of the trough (2)
supplied to Since the trough (2) is vibrating linearly in the direction of arrow a, the sieve material supplied from the supply port (6) forms a certain layer thickness and is transferred to the right in Fig. 1 due to vibration. . During this process, the sieve net (3) separates the sieve into an upper sieve and a lower sieve, and according to this embodiment, five sieve net vibration drive units (12) are fixed to the sieve net. As shown in Figure 4, the current coil (29
) is energized with alternating current, so an alternating attraction force is generated between it and the movable core (27), which causes the rod (26) to vibrate in the vertical direction. Therefore, the sieve screen (3) fixed at its tip is vibrated. Note that this drive unit (12
) The frequency of the alternating current applied to the coil is set to be sufficiently high, and the sieve net (3) vibrates at a correspondingly high frequency to apply an impact force, and the sieve material on top of this vibrates at a high frequency. The material can be sieved sharply into the top and bottom of the sieve without clogging. Therefore, in Figure 1, the sieve material carried to the right side of the trough (2) is discharged to the outside from the sieve material outlet (4), and the sieve material is discharged to the outside from the sieve material outlet (5). is discharged.

As described above, the material is sieved on the sieve net (3), and the material under the sieve falls onto the bottom wall (2a) of the trough (2). The trough is then transported over this bottom wall by linear vibration, and during this process, the bottom wall (2a) of the trough has a cylindrical protrusion (25 ) is formed, so
It is transported around this circumference and does not enter into this cylindrical protrusion (25). The vibration drive unit (12) will not enter the casing (21). Furthermore, according to this embodiment, a cylindrical rubber covering member (3
51 is fixed, so that the material under the sieve is completely prevented from entering the casing (21) of the drive section (12). Furthermore, since the umbrella member (31) is attached to cover the increased diameter part (32), the material under the sieve avoids the protrusion (25) and falls onto the bottom wall (2a) of the trough (2). Therefore, the casing (2) of the drive section (12)
1) Not only does it prevent intrusion into the inside of the screen, but it also extends the life of the rubber covering member (35) (because the material under the sieve does not leak directly). Also, the sieve net (3) and the bottom wall (2al) of the trough (2) perform relative vibrations, but this is because the cylindrical member (31) is made of rubber.
The vibration of the rod (26) is absorbed by this deflection and does not have any harmful effect.
