Description

[Detailed Description of the Invention] This invention relates to a sorting net device for a vibrating sieve that aims to improve the separation efficiency when separating elongated workpieces.

Conventionally, the mesh surface of a blind screen was simply made of thin rods lined up at a predetermined interval, so workpieces often bridged onto two adjacent thin rods and moved as they were, making it impossible to screen them. .

However, in this invention, protrusions were provided on the rod or the protrusions were suspended from above the rod, so when separating a workpiece and a polishing stone, for example, the workpiece, which is moving in the form of a bridge, collides with these protrusions. The polishing stone then changes direction, becomes parallel to the rod, and easily falls through the gap, and the polishing stone moves from above the rod toward the exit, and the workpiece and the polishing stone are screened out.

Therefore, all of the mass thrown onto the blind screen is separated into polishing stones and workpieces, thus solving the above-mentioned problems of the conventional method.

That is, to explain this invention with reference to the embodiment shown in FIG. Mounting plates 3, 3 are installed at right angles, and the rods 2, 2 are mounted on the lower surface of the mounting plate 3.3.
A sieve screen is constructed by hanging projections 4, 4 that reach the upper surface of the screen.

The protrusion may hang down so as to touch the upper surface of the rod, but usually it hangs down so as to slightly protrude into the gap on the adjacent rod.

However, it is desirable that at least adjacent protrusions are arranged, for example, in a staggered manner so that they are not parallel to each other in the direction perpendicular to the rod.

Next, the embodiment shown in FIG. 2 has a large number of rods 6 inside the frame 5,
6 are arranged in parallel at a predetermined interval, and protrusions 7, 7 are provided on the upper surface of the rods 6.6 so as not to be adjacent to the rods in a perpendicular direction to constitute the sieve screen of this invention.

In each of the above embodiments, a vibration motor (not shown) is attached to the frames 1 and 5, and when the motor is started, the mass vibrates. Move in the appropriate direction.

Therefore, when the workpiece 10 moves onto the rod in a bridge-like manner, it collides with the protrusions 4 and 7 and is forcibly changed in direction, and finally becomes parallel to the rod and falls from the gap between them. become.

Therefore, even if the sieve screen is not made long in the direction of movement,
Screening can be easily completed in a relatively short period of time, and there can be no workpieces that are not screened.

That is, according to this invention, since the protrusions are provided on the rods of the blind screen, it is possible to prevent the workpiece from moving in a cross-linked manner, thereby eliminating any sieving defects.

Furthermore, since the sieving efficiency is improved, the length of the sieve can be made relatively short.
