DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. Reference numeral 1 denotes an automatic cleaning device for a vibrating sieve according to the present invention, which comprises a known vibrating sieve 2 and a cleaning device 3 mounted on the vibrating sieve 2. The configuration of the vibration sieve 2 is as follows. A base tray 2C in which a sieve mesh 2B made of stainless steel mesh is mounted on a cylindrical base 2A having a built-in vibration mechanism is supported by a spring 2D. An undersize discharge port 2E is provided on the side surface of the base tray 2C, and an oversize discharge port 2G is provided on the side surface of the top rim 2F provided on the base tray.

A motor 2H is vertically mounted on the base tray 2C, and a top weight 2I and a bottom weight 2J are respectively mounted above and below a shaft of the motor, and a phase is set by a lead collar 2K at a shaft end.

The principle of the vibrating sieve is as follows. The vibrating sieve basically has a sieve surface vibrating about the center of gravity of the mass, and the vibration is generated by a top weight and a bottom weight attached to both ends of a motor or a shaft. The rotation of the top weight generates a circular vibration in the horizontal plane, and serves to move the material supplied to the center of the sieve surface in the peripheral direction. The rotation of the bottom weight causes the sieve surface to tip over, generating vertical vibration. These vibrations are combined to cause a special three-dimensional gyre movement on the sieve surface. By changing the phase of the bottom weight relative to the top weight, the nature of the vibration changes and the material on the sieve moves. Therefore, by changing the phase of the top weight and the bottom weight, it is possible to obtain the movement of the sieve suitable for the properties of the processed material.

[0008] The structure of the cleaning device 3 is a portal frame 4,
It comprises a charge nozzle section 5 and a cleaning nozzle section 6. The portal frame 4 is composed of columns 4A, 4A standing on the left and right sides of the vibration sieve 2 and a horizontal frame 4B suspended on the upper ends of the columns, and the horizontal frame is formed by a top rim 2 of the vibration sieve.

Numeral 1 is rotatably supported by a bearing 5A3 provided on a horizontal frame, and a washing water inlet case 5A4 is connected to an upper end of the inner vertical rotating pipe via a mechanical seal 5A41. A V-pulley 5A5 is attached near the upper end, and this V-pulley is connected to a geared motor 5A6 provided on a horizontal frame of the portal frame by a pulley.

The outer vertical pipe 5B is an inner vertical rotating pipe 5A.
And the upper end of the outer vertical pipe is fixed to the horizontal frame of the portal frame. The pipe-shaped feeding case 5C is configured to cover the outer vertical pipe 5B with the passage 5C1 remaining therebetween, and the upper end of the pipe-shaped feeding case is fixed to the horizontal frame of the portal frame.

To wash the sieve mesh 2B. In this case: a. Since the cleaning nozzle pipe 6A rotates around the inner vertical rotation pipe 5A, the entire surface of the sieve mesh 2B can be reliably cleaned. b. The driving force is transmitted from the geared motor 5A6 to the V-belt, and turns the V-pulley 5A5 to operate on the inner vertical rotation pipe 5A. In this case, the power used is as small as 0.1 kW, which is suitable for rationalization. b. Since the mechanical seal is used as the water sealing device for the washing water, the rotation of the inner vertical rotation pipe is slow, but there are few failures. c. When used as a vibrating sieve, the raw material is fed by passing it through the raw material feeding horizontal pipe 5C2 and the raw material discharge port 5D41 of the charge nozzle body 5D and dropping the raw material into the sieve net 2B of the vibrating sieve.
