Abstract

PROBLEM TO BE SOLVED: To provide a sieve shaker which prevents the generation of clogging. SOLUTION: A stretched rope 5 of a synthetic resin is welded to the lower surface 1d of a net main body 1 of a synthetic resin and fitting parts 8 are formed on both end sides of the rope and held by a fixture 9. When the fixture is set in a sieve shaker, the rope is stretched, but tension is not applied to the net main body. Therefore, when vibration is applied to the net main body in this state, the net main body is vibrated vertically and complexly to be prevented from being clogged.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrating screen used in a vibrating screen apparatus for removing and sorting mud components and the like from quarry, crushed concrete and the like.

[0002]

2. Description of the Related Art In a vibrating screen, a vertical line made of synthetic resin and a horizontal line made of synthetic resin are crossed to form a mesh of a predetermined size. When the net is set on a vibrating sieving apparatus, the net is always in tension because both ends of the net body are pulled by fixings.

[0003]

When the raw material is sieved by vibrating the tensioned net, clogging occurs because secondary vibration, that is, vertical vibration cannot be obtained. Therefore, it is conceivable to reduce the tension of the net so that the net can vibrate in the vertical direction. However, in this case, the net is hit and damaged.

[0004] In view of the above circumstances, an object of the present invention is to prevent clogging and to prevent breakage of a net.

[0005]

SUMMARY OF THE INVENTION The present invention provides a network body,
It is characterized by comprising a tension rope fixed to the lower surface of the net body, and mounting portions provided at both ends of the tension rope.

The present invention provides a net body formed of a synthetic resin wire, a synthetic resin tension rope welded to a lower surface of the net body, and both ends of the tension rope provided at both ends of the tension rope. And a mounting portion protruding from the mounting portion.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present inventor has conducted various experiments and studies to solve the above-mentioned problems. As a result, a plurality of synthetic resin tension ropes are arranged and welded in parallel on the lower surface of the synthetic resin net body, and at the time of setting, both ends of the tension rope are clamped by a fixture. It turned out that the fixture should be pulled and fixed. With this configuration, the net body can be vibrated in the vertical direction, and the net body is also fixed to the tension rope, so that the net body is not hit.

The synthetic resin wire and the synthetic resin tension rope are made of, for example, polyethylene, but may include a wire. The diameter of the wire is appropriately selected as needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The net body 1 is formed in a mesh by a synthetic resin vertical wire 2 and a synthetic resin horizontal wire 3 that intersect each other. The size (mesh) of the mesh is appropriately selected as needed. Polyurethane having high abrasion resistance is used as the synthetic resin, but is not necessarily limited thereto. The wires 2 and 3 are fixed by welding.

The vertical wire 2 is disposed in the flow direction A of the raw material, and the horizontal wire 3 is disposed in a direction perpendicular to the flow direction A of the raw material. The wires 2 and 3 include a wire 2
a and 3a are built in. The diameter of the wire 2a is
Although formed larger than the diameter of the wire 3a, the size of the diameter is appropriately selected as needed.

On the lower surface 1d of the net body 1, a plurality of tension ropes 5 made of synthetic resin are stretched in parallel with the horizontal wire 3 and fixed. The tension rope 5 is made of, for example, polyurethane, and has a wire 6 built therein. At both ends of the tension rope 5, mounting portions 8 are provided, and the mounting portions 8 protrude from both ends 1a and 1b of the net main body 1. The tension rope 5 and the vertical wire 2 are fixed by welding.

The tension rope 5 and the wire 6 are designed to have a diameter that can withstand tension. For example, the diameter of the tension rope 5 is 6 mm. The parallel interval L between the adjacent tension ropes 5 is also appropriately selected as needed, and for example, the interval L100 mm is adopted.

The attachment portion 8 of the tension rope 5 includes a fixing device 9.
, And fastened with screws 10. On the left end 1 a side of the net body 1, an edge protection sheet 11 whose tip is located on the fixing tool 9 is provided.

Next, the operation of this embodiment will be described. A clamping bar 15 is provided inside the casing C of the vibration sieving apparatus. This crumbing bar 1
5 is engaged with a fixing tool 9 holding the net body 1 and fixed. Then, the tension rope 5 is in a tension state.

When the vibration motor fixed to the casing C is driven, the casing C vibrates, and vibration is applied to the net body 1. At this time, the net body 1 has its both ends 1a, 1a.
Since b is not pulled by the fixture 9, it also vibrates in the vertical direction. Therefore, because it repeats complicated vibrations,
Clogging can be prevented. Further, since the net main body 1 is fixed to the tension rope 5, the net does not undulate and is not broken.

The embodiment of the present invention is not limited to the above. For example, instead of the synthetic resin wires 2 and 3 incorporating the wire and the synthetic resin tension rope 5, a synthetic wire not including the wire is used. It is also possible to use a resin wire and a synthetic resin tension rope, or a wire and tension rope consisting only of a wire.

[0017]

As described above, according to the present invention, the tension rope is fixed to the lower surface of the net body, and the attachment parts are provided at both ends of the tension rope. When the fixture is set on the vibrating sieving device, the tensioning rope is tensioned, but no tension is applied to both ends of the net body.
Therefore, when vibration is applied to the net body in this state, the net body also vibrates in the vertical direction, resulting in complicated vibration, and thus clogging can be prevented.

If a synthetic resin wire and a synthetic resin tension rope are used, they can be welded when they are fixed, so that the production becomes easy. When polyethylene is used as the synthetic resin material, the wear resistance can be improved.
