This rotary sieving machine is of a so-called fin screen type, in which a plurality of drums rotating in the same direction are provided in parallel on a gantry, and the outer periphery of each drum is made of an elastic material such as rubber, and a projection is provided on the outer periphery. A plurality of circumferential flanges having at least one are attached at required intervals in the axial direction of the drum so as to form a sieve.

回転篩を提供することを他の目的とする。However, in the conventional rotary sieve, since a circumferential flange having a projection for catching an object such as dust is formed of an elastic body, foreign matter is caught. In this case, the circumferential flange partially bends to prevent the breakage, but the protrusion is thin and easily deformed, so that the conveying force of the workpiece is weak, and the front edge of the protrusion is in the radial direction of the drum. , There is a problem that the string-shaped object is easily entangled. Also, when the material to be treated is an adhesive raw material,
There is a problem that deposits accumulate on the circumferential collar and the sieving function is reduced. Further, there is a problem that the material to be processed is piled up in the charging portion, and the dispersion to the side is not performed well. Therefore,
The present invention does not cause breakage at the time of biting a foreign substance, but can significantly increase the conveying force of the product on the sieve and improve the discharge of the product under the sieve. An object of the present invention is to provide a rotary sieve capable of preventing entanglement of an object to be processed. It is another object of the present invention to provide a rotary sieve capable of preventing clogging of a sieve by an adhered substance and dispersing an object to be processed uniformly around a charging section.

And a large number (12 in this embodiment) of arms 10 projecting integrally from the outer periphery of the boss 8 at equal intervals and projecting backward in the rotation direction 9 of the rotating shaft 2.
It is composed of The sieve forming member 7 is fitted with a shaft hole of the boss 8 through a key when the intermediate portion of the rotary shaft 2 has a circular cross section, or a boss when the intermediate portion has a rectangular cross section. The shaft hole of No. 8 is fitted as a square to be fitted therewith. The arm 10 has a rectangular cross section,
And it is provided so that it becomes slightly thinner as it goes from the base to the tip, and as shown in FIG. 2, when the adjacent tips are located symmetrically with respect to the line L1 connecting the axes of the rotary shafts 2, in which the upper edge of the upper arm 10 is curved to substantially match the line L 2 connecting the upper ends of the bosses 8. On the other hand, the opening in the width direction of the sieve screen 1 by each sieve forming member 7 is the length of the boss 8 and a spacer (not shown) fitted to the rotating shaft 2 between the adjacent bosses 8. Alternatively, it is determined by the width of the arm 10, and the opening in the longitudinal direction of the sieve frame 1 is determined by the interval between the rotating shafts 2, the outer diameter of the boss 8, or the length of the arm 10.

きる。 [0008] The rotary sieve having the above construction is installed by setting the sieve frame 1 horizontally or inclined, or by bending the sieve frame 1 so as to have an inclined portion and a horizontal portion. Is used adjacent to the transport end. When the object to be processed is put on each sieve forming member 7 at the other end (the left end in FIG. 1) of the sieve frame 1, the arm 10 becomes larger as the rotation shaft 2 rotates. 1, the object to be processed is flipped up in the transport direction 11 indicated by the arrow in FIG. 1 and is transported and unraveled while being transported, and while the object to be processed smaller than the sieve formed by each sieve forming member 7 falls, An object to be processed larger than the sieve is transferred to one end and sieved. In this sieving, when the sieve frame 1 is horizontal, there are two kinds of products, an on-sieve product and a under-sieving product. Since it falls under its own weight along the slope of the sieve frame 1, it is classified into three types. Further, when a wind separation mechanism is additionally provided, the products on the sieve are classified into two types. Arm 10
Is curved, the arm 10 effectively applies the object to be processed on the upper portion of the boss 8 larger than the aperture to the flow of the main product on the sieve, so that the conveying force of the object to be processed can be greatly increased. The object to be processed, which has passed through the opening, can be dropped without being unnecessarily flipped up, and the object in the form of a string can easily escape from the arm 10, so that entanglement of the object can be prevented, while foreign matter is caught.

In the figure, reference numeral 15 denotes a spacer. Other configurations are the same as those of the first embodiment, and therefore, the same components are denoted by the same reference numerals and description thereof will be omitted. According to the rotary sieve having the above-described configuration, the crown is formed in the charging portion of the sieve at which the processing object is charged, so that the processing object can be evenly dispersed around the charging portion.

Since it is not flipped up, it is possible to greatly increase the conveying force of the product on the sieve, improve the discharge of the product under the sieve, and easily escape the string-shaped object from the arm. Therefore, the entanglement can be prevented, while the arm is easily flexed when the foreign matter is caught, so that the breakage of the sieve forming member can be prevented. Also , sieve forming member
With itself becomes provided with a scraper function, the scraping of the ball scan or arm attachment or entangled object to be processed is possible, the structure and mounting of the scraper, the adjustment easy
At the same time, it is possible to prevent the sieve from being clogged by deposits and the like. Further, by appropriately increasing the width and length of the arm of the sieve forming member corresponding to the input portion of the object to be processed, as compared with the other portions, a crown is formed at the input portion of the object to be processed in the sieve, The processing object can be evenly distributed around the charging section.
