Description

[Detailed description of the invention] This invention relates to a device for preventing clogging of the mesh of a vibrating sieve machine that sieves various ores, earth and sand, etc., and its purpose is to prevent block rolling and block and wire rolling. Therefore, it is an object of the present invention to provide a clogging prevention device that has a wide range of action, makes little noise, is wear resistant, and can withstand long-term use.

Conventionally, as this type of clogging prevention device, for example,
Various devices have been proposed as disclosed in Japanese Utility Model Publication No. 28275, Japanese Utility Model Publication No. 46-1476, and Japanese Utility Model Publication No. 48-32070, etc., but the conventional products have a limited and narrow action range of the block. For example, there are disadvantages such as clogging at the corners of the mesh, resulting in poor working efficiency, high noise, and excessive wear, which makes it difficult to withstand long-term use.

This idea was devised in consideration of these points.The idea is to form a through hole approximately in the center of a block made of a wear-resistant polymer, and insert a wire coated with an abrasion-resistant polymer into the through hole. Then, a large number of blocks are fixed to the wire at intervals, and a rotating metal fitting is rotatably provided on a frame over which a mesh is stretched, and one end of the wire is connected to the metal fitting. The main point is that the blocks and wires are configured to roll on a mesh body.

Next, an embodiment of the clogging prevention device of the present invention will be described based on the drawings.

1 is a wire, and the wire 1 is formed by coating a steel wire 2 with a wear-resistant polymer 3 such as polyurethane, nitrile rubber, or polyester. The steel wire 2 may be passed through the tape, or the polymer solution may be applied to the surface of the wire 2 and dried to form a film.

4 is a block that is more durable than wear-resistant polymers such as polyurethane, polyamide, acrylic resin, phenolic resin, melamine resin, nitrile rubber, and polybutadiene, and its shape may be a truncated cone as shown in Figure 1. It may have a cylindrical shape as shown in FIG. 2, or it may have a plurality of straight protrusions 5 integrally formed on the outer peripheral surface of the cylinder as shown in FIG. As shown by the imaginary line in FIG. 3, the shape is one in which a plurality of linear protrusions 5a are integrally formed, protruding in the radial direction and extending at an angle to the axis. The shape may be arbitrary.

The outer circumferential surface of the block 4 may be arbitrarily divided into two halves in the axial direction, as shown in FIG. In some cases, a large number of protrusions 6 having a shape are formed so that the transfer direction of the block 4 is guided by the protrusions 6.

A large number of blocks 4 are attached to the wire 1 at intervals as shown in FIG. 5, and the means for attaching them will now be explained in detail.

As shown in FIG. 1, a through hole 10 consisting of a large diameter portion 7 and a small diameter portion 8 and having a stepped portion 9 is formed around the four blocks, and a metal ring 11 is fitted over the wire 1.
The metal ring 11 is fixed to the wire 1 by pressing a part of the metal ring 1, and the wire 1 is inserted into the through hole 10 and the metal ring 11, and the metal ring 11 is positioned inside the large diameter part I. In the drawings, the step part 9 is mounted so as to be supported on the upper surface.

Therefore, when the block 4 is attached to the wire 1 in this way, the block 4 can freely rotate with respect to the wire 1,
It also moves along the wire 1 within the range shown in FIG. 5d.

Also, it is installed as shown in FIG.

That is, a circular recess is formed in the center of one end face of the block 4, and a metal ring 15 having a screw hole 14 formed in the peripheral wall is fitted and fixed into the recess to be connected and integrated with the block 4. A through hole 16 having a diameter equal to the inner diameter of the screw hole 15 is formed continuously in the metal ring 15, and a round hole 17 in the radial direction communicating with the screw hole 14 is formed in the block 4.
The wire 1 is inserted into the metal ring 15 and the screw hole 1 is inserted into the metal ring 15.
Block 4 is tightened by tightening screw 18 screwed onto block 4.
A large number of blocks 4 are attached to the wire 1 at intervals, and in this case, the block 4 rotates together with the wire 1.

The clogging prevention device of the present invention is constructed as described above, and is used by being placed on the mesh of a vibrating sieve. In the case of a device that rotates all at once, a rotating fitting is connected to the end of the wire 1 as shown in Fig. 6, and the wire 1 and the block 4 are transferred on a mesh through the rotating fitting. It is placed there.

The rotating fitting is constructed as shown in FIG.

That is, 19 is a rotating metal fitting body which has a hook part 20 that can be opened and closed freely on one side and a locking body 21 on the opposite side.
The ring 22 is rotatably attached to the locking body 21 of 9, and the layer 22
While connecting the end of the wire to the wire, the hook 20 is connected to the hook 25 fixed to the mesh 230 frame 24 shown in FIG. 7, and the wire and block 4 are placed on the mesh 23 and rolled as described above. This is how it is used.

In the case where the block 4 rotates with respect to the wire shown in FIG. 1, an annular portion 26 is formed at the end of the wire as shown in FIG.
It is used by locking it in.

That is, in any of the embodiments, the blocks 4 are used by being placed on the mesh 23 freely.

Next, the effects will be explained in detail.

Since the block 4 is made of a wear-resistant and elastic material such as polyurethane, polyamide, acrylic resin, phenol resin, melamine resin, nitrile rubber, or polybutadiene as described above, the block 4 has appropriate elasticity and has a mesh structure. 23, and the jumping does not generate any noise.

In addition, the mesh 23 is struck with an appropriate force to prevent clogging, and since it is made of a wear-resistant material as described above, it is resistant to wear and can withstand long-term use.

Further, the wires that attach the blocks 4 at intervals are coated with a wear-resistant polymer, so that they are wear-resistant and can withstand long-term use like the blocks 4.

Further, the wire is configured to be located approximately at the center of the block 4.

In other words, the mesh 23 is formed at a height corresponding to the radius of the block 40.
Since the wire is located above the mesh 23, the wire has less chance of directly touching the earth and sand flowing on the mesh 23 or being buried in the earth and sand, so there is less abrasion with the earth and sand, and the wire is less likely to wear out.

In addition, the block 4 rotates around the wire that passes through the approximate center of the block 4 or together with the wire, and from the moment it falls from the jumping position and hits the mesh 23, it rolls on the mesh 23 and hits the mesh 23. Remove the clogged powder and granules.
The rolling pressure causes it to peel off and fall.

In addition, since the wire jumps and rolls as described above, the action range of the plot and wire is wide, and the mesh at the corner is not clogged.

In addition, since the flock is transferred from one place to another, the flock is fixed to a fixed wire in the past, and unlike the case where one part of the block hits the mesh 23, uneven wear does not occur, and wear occurs on average, resulting in long-term use.

In addition, in the case where the outer peripheral surface of the block 4 is formed with a large number of protrusions 6 that are inclined in a certain direction as shown in FIG. If you fall on a surface with a raised protrusion 6a, the protrusion 6a
a, the block 4 rolls to the left, and when the surface on which it falls is a protrusion 6b that slopes downward to the right, the block 4 and the wire 1 are guided by the protrusion 6b. It rolls to the right.

That is, when the protrusion 6 as described above is formed, the block 4 and the wire are guided by the protrusion 6, so the block 4
And the rolling range of the wire 1 becomes wider.

As is clear from the above explanation, since the block 4 is made of a wear-resistant polymer, it is durable, has little noise, and can be obtained with a striking force due to appropriate repulsion.

Furthermore, since the block 4 and the wire 1 can be transferred, the range of movement of both is wide, and the meshes 23 at the corners do not get clogged, and the wires 1 do not wear out unevenly.

In addition, since the wire 1 coated with a wear-resistant polymer is used and is located in the center of the block 4, there is less wear and durability, and in combination with the block 4, long-term use is possible. It is.

Since the clogging prevention device of the present invention is constructed as described above, the movement range of the block and wire is wide and the mesh does not become clogged, and it is also less noisy, has long needle wear resistance, and can withstand long-term use along with the mesh.
