Abstract

PROBLEM TO BE SOLVED: To improve sieving efficiency. SOLUTION: A base plate 6 is installed in a stand 5 in a manner that the pate 6 can swing. Consequently, since a sieve in the upper side of stacked sieves swings considerably and the sieves swing less as the sieves are in a lower side and object substances to be sieved existing in a higher mixing ratio among object substances including those with higher mass and those with lower mass mixed together can be sieved by the sieves which are swung significantly, the object substances to be sieved can be efficiently stirred and the sieving efficiency can be improved. Further, a rotation plate 7 is installed above the base plate 6 while being made movably up and down, and since the rotation plate 7 is moved up and down, clogging of the sieves and uneven distribution of the object substances to be sieved owing to scooping up of them can be solved. A plurality of sieves 2a to 2g are stacked in the rotation plate 7 and a hitting part 8 is uprightly installed in the base plate 6 in a manner that a hitting part 8 hits the side faces of the sieves, and accordingly, the sieving effect is collectively improved owing to the swinging movement, solution of the clogging and uneven distribution problems, and hitting force applied to the sieves.

In the above-mentioned conventional sieving apparatus, when the rotation center of the rotary plate is eccentrically rolled, the sieves 2a to 2g are rolled with the same amplitude. However, for sieves 2a to 2g, the particle size (mass) passed through the sieve mesh
Since the objects to be sieved are different from each other, the objects to be sieved include both large and small masses such as sieve 2a.
Is insufficient and the sieving takes a long time.

[0005] In addition, since the state in which the large and small masses are mixed increases as the sieves 2d, 2c, and 2b move upward, the shaking force of the sieve is insufficient, and it takes time to screen. There's a problem. Ideally, it is preferable that the sifting force of the sieve 2a is large and the swaying force is reduced toward the sieves 2b to 2g.

Further, in the conventional sieving apparatus, since a beating is applied to the side surface of the sieve only in one direction, an impact force is applied only to the object to be sieved in the sieve from one direction. In addition, there is a problem that an object to be sieved may be biased in the sieve, and the sieving takes time.

According to the first aspect of the present invention, since the base plate is provided on the base so as to be swingable, the stacked upper sieve shakes greatly, and the shaking is reduced toward the lower sieve, and the mass is reduced. A large sieve in which a large sifted object and a small sifted object are mixed can be greatly shaken, so that the sifted object can be efficiently stirred and the sieving efficiency can be improved. Also, since a rotating plate is provided on the base plate so as to be able to move up and down, and the rotating plate can be moved up and down,
The rotating plate can be moved in a figure 8 and precession movement can be performed in combination with the above-mentioned swinging, so that clogging of the sieve can be eliminated and deviation due to jumping of the object to be sieved can be eliminated. A plurality of sieves are stacked and placed on a plate, and a hitting portion is erected on the base plate so as to hit the side surface of the sieve, and the swing, clogging and bias can be eliminated, and an impact force can be given to the sieve. In addition, the sieve efficiency can be improved.

According to the second aspect of the present invention, a projection is provided on the back surface of the rotating plate, and a vertical driving unit that generates vertical vibrations on the sieve in accordance with the rotation of the rotating plate by passing over the projection is used as a base. It is erected on a plate, and the sieve is subjected to rocking, striking by the hitting portion and vertical vibration, and the vertical vibration eliminates clogging and deviation of the sieve, so that the sieve can be sieved. Sieve efficiency can be improved.

According to the third aspect of the present invention, a cam portion is provided so as to protrude from the peripheral edge of the rotating plate, the striking portion is rotated by a rotating arm abutting on the cam portion, and the striking element is sieved by a tension spring. By changing the rotation speed of the rotating plate by striking against the side, the longitudinal vibration caused by the protrusions and the cycle of the impact by the impact part can be adjusted according to the type of the object to be sieved, improving the sieving efficiency. can do.

According to the fourth aspect of the present invention, a vibration generator is attached to the rotating plate support shaft, and in addition to the longitudinal vibration caused by the projections, a vertical vibration is applied to the sieve according to the type of the object to be sieved. Since bias due to clogging and splashing can be eliminated, sieve efficiency can be improved.
