The driving unit includes an end rod that is movably supported and a bent portion is rotatably supported by the lower end of the link plate, and a filter cloth tapping rod that is fixed to the lower end of the end rod and taps the filter cloth. The filter cloth is suspended between filter plates in which the vibrating mechanism is opened by the driving of the means. When descending toward the bar, each end bar rotates about the connecting part with each link plate by pushing the bar up relative to the filter cloth hanging bar after pushing the bar relatively. Then, the filter cloth tapping rod provided at the end portion of the end rod is configured to vibrate the filter cloth by abutting against and hitting the filter cloth.

According to a second aspect of the invention, in the invention of the first aspect, when the upper end is fixed to the vibrating rod and the lower end is fixed to the pounding rod, the tapping rod rises against the biasing force. It is also possible to provide a spring for urging it to descend to the position. According to a third aspect of the present invention, in the first or second aspect of the present invention, the abutting rod protruding from the lower surface of the vibrating rod toward the knocking rod may be provided.

By using the rectangular link mechanism, the filter cloth suspension rod contacts the tapping rod and pushes it up relatively, so that the end rod rotates and the filter cloth tapping rod at the lower end of the end rod contacts the filter cloth. Then, the filter cloth was tapped to apply vibration. As a result, the single drive means can cause the vertical movement of the vibration mechanism and the transmission of the vibration from the vibration mechanism to the filter cloth suspension rod, and the structure of the drive means becomes simple and inexpensive. . Further, since the tapping rod, which is a part of the vibrating mechanism, is simply brought into contact with the filter cloth suspension rod without capturing the filter cloth suspension rod, the means for capturing the filter cloth suspension rod is simple. Will be things.
