Abstract

PURPOSE:To provide a shell removing rotary wire brush having a high efficiency and a long life without imparing the coated surface. CONSTITUTION:Multiple steel wire bundles each twisted with multiple small- diameter hard steel wires on the outer periphery of a horizontal circular presser plate are twisted to form a unit wire brush 1 so that the cross section is located at each vertex position of a regular polygon, and multiple equal-length unit wire brushes 1 are radially protruded along the conical surface at uniform intervals to form a shell removing rotary wire brush. The tip section of the unit wire brush 1 is protruded into a circular arc shape, roots are integrally brought into contact with each other to form a tear drop shaped loop R, the loop root is caulked with a ring-shaped holding metal 4 to form the loop-shaped unit wire brush 1, and the faces R of the loop sections of the unit wire brushes 1 are arranged along the conical surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating wire brush for shellfish removal, which is mounted on a robot for cleaning shellfish underwater.

[0002]

2. Description of the Related Art As a rotating wire brush attached to an underwater shell removing robot, a rotating wire brush having a structure as shown in a vertical sectional view of FIG. 3 is conventionally known. That is, a rotary wire brush is fitted to the lower end of the rotary shaft of the vertical submersible motor 11, and the rotary wire brush is attached by the pressing plate 13 and the mounting plate 14 so as to rotate in sliding contact with the cleaning surface. In this type of rotary wire brush, a large number of rod-shaped wires are radially projected from the outer periphery of the pressing plate 13 along the generatrix of the conical surface as a unit wire brush, and as a whole, a deformed shape that expands downward in a skirt shape. It has a flat cone shape. Here, a hard steel wire is used as the material of each unit wire brush, and as shown in FIG. 4, a steel wire bundle formed by twisting a plurality of steel wires having the same diameter is shown in FIG. To
Each vertex of the regular hexagon is arranged like a snowflake, and the center of the brush is crimped by crimping metal fittings (lead) 16 to prevent the wires from coming apart.

[0003]

However, in the wire brush having such a crimping metal fitting for preventing the brush from coming loose in the central part of the brush, the crimping metal fitting does not come into contact with the cleaning surface on a flat cleaning surface. However, when there is unevenness such as a welding beat on the cleaning surface, there is a problem that the caulking metal fitting contacts the convex portion and scratches the painted surface.

The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a highly efficient and long-life economical rotating wire brush for shellfish removal without damaging the painted surface. .

[0005]

To this end, according to the present invention, a plurality of steel wire bundles formed by twisting a plurality of small-diameter hard steel wires are provided on the outer periphery of a horizontal circular pressing plate at each vertex position of a regular polygonal cross section. In a rotating shell brush for shellfish removal, in which a plurality of unit wire brushes of equal length that are twisted so as to project radially along a conical surface at equal intervals, each unit wire brush has an arcuate tip. To form a teardrop-shaped loop in which the bases are in contact with each other to form a teardrop-shaped loop, and the loop bases are crimped with an annular loop holding metal fitting to form a loop-shaped unit wire brush, and the loop portion of each unit wire brush Is arranged along the conical surface.

[0006]

According to this structure, the following actions are performed. (1) Since the distal end is formed into a deformed elliptical loop having a long teardrop shape that is curved in a substantially semi-circular shape in the radial direction, the elliptical loop portion at the distal end does not stimulatingly contact the cleaning surface. Further, since the root portions of the many oval loop portions are fixed to the pressing plate by the ring-shaped holding metal fittings, each unit wire brush does not come apart. (2) In addition, the root of each unit wire brush is located near the brush mounting metal, and that part is fixed with a ring-shaped metal holder made of rigid metal. Do not make direct contact. Therefore, the painted surface is not damaged.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. FIG. 1 is an overall plan view of the wire brush, and FIG.
It is an enlarged view which shows the unit wire brush of.

In the above figure, the unit wire brush 1 has the same waist strength as that of the conventional one in order to make the shell removal ability the same as the conventional one, and twists a plurality of hard steel wires having excellent wear resistance. The steel wire bundles are combined together, and further, they are bundled in a hexagonal snowflake shape and twisted to form a loop type brush wire 2. The tip of the unit brush wire 1 is an arc having a radius R, and the root A of the loop is the brush mounting bracket 3
It is as a part close to. Then, the portion is fixed by the ring-shaped loop holding metal fitting 4. The root A of each unit wire brush is located near the brush mounting member 3, and that part is crimped and fixed by the ring-shaped loop holding member 4. Here, the loop portion R of each unit wire brush 1 is arranged at a position along the conical surface of the wire brush. According to this structure, even if the cleaning surface has irregularities, the ring-shaped holding metal fitting 4 does not directly contact the irregular surface.

[0009]

According to such a rotating wire brush for shellfish removal, the following effects can be obtained. (1) Since the caulking metal fitting of the unit wire brush is located at the root of the loop, it does not come into direct contact with the irregularities on the cleaning surface, so that the coating on the cleaning surface is not damaged. (2) Further, since the twisted wires are bundled and further twisted, each wire does not come apart. This significantly extends the life of the brush and significantly reduces brush wear costs. (3) Furthermore, since the unit wire brush has a loop shape instead of the conventional rod shape, the number of wires that are useful for shell removal is doubled, and it is not the effect of simply doubling the number of rod wires, By forming a loop portion that is made into a flat shape, and this loop surface makes sliding contact with the surface to be cleaned, the strength and rigidity are optimized, and the shell removal performance is excellent. (4) The unit wire brush has a loop shape. Therefore, by using this loop, the wire brush can be stored, replaced, disassembled, and
Easy to assemble.

In short, according to the present invention, a plurality of steel wire bundles, each of which is formed by twisting a plurality of small diameter hard steel wires, are twisted around the outer periphery of the horizontal circular pressing plate so that the cross section is at each vertex of a regular polygon. In a shell wire removal brush for shellfish removal, in which a plurality of unit wire brushes of equal length are radially projected along a conical surface at equal intervals, the tip of each unit wire brush is curved in an arc shape. A loop-shaped unit wire brush is formed in which the roots come into contact with each other to form a single teardrop-shaped loop, and the loop roots are swaged with an annular loop holding metal fitting, and the surface of the loop portion of each unit wire brush is the conical shape. The present invention is extremely useful industrially because the rotary wire brush for shelling which is highly efficient and has a long life without damaging the painted surface can be obtained by arranging the shell along the surface.
