Description

[Detailed Description of the Invention] The present invention relates to a frame protection structure in a sieve device, hopper, etc.

Generally, in a sieving device, a sieve screen having a large number of through holes is placed on the top of a base frame, and the processed material transferred onto the sieve screen is sieved to a specific particle size.

A reinforcing frame is fixed to the lower part of the base frame of the sieve device to make the base frame strong, and the reinforcing frame has a plurality of reinforcing frames arranged vertically, horizontally, diagonally, etc. However, the reinforcing frame is subject to severe wear if left as it is because the processed material falls through the holes and collides with the reinforcing frame.

Therefore, conventionally, as shown in FIGS. 8 and 9, protective materials a and b are attached to the surfaces of reinforcing frames c and d to prevent the above-mentioned wear.

That is, the protective material a is formed by fixing an L-shaped metal liner e that covers the top and side surfaces of the groove-shaped reinforcing frame C to the reinforcing frame C using countersunk bolts f and nuts g.

However, in the above-mentioned protective material a, the metal liner e has inferior abrasion resistance compared to the rubber liner, so it is easily worn out by collisions with processing objects, has a short durability life, and increases in weight as the liner thickness increases. The problem is that it becomes difficult to handle, and if it wears out and falls, the lower equipment will be damaged.Furthermore, since it is made of metal and is heavy, replacement work is complicated, and the reinforcing frame is difficult to handle. C
Since the metal liner and the metal liner e are rigid bodies, a gap is likely to be formed between the metal liner e and the material to be processed, which causes the reinforcing frame C to wear out and provide insufficient protection.

The protective material is made by wrapping a flexible liner h such as an old belt around the outer circumferential surface of the cylindrical reinforcing frame d, overlapping both ends and securing with bolts i and nuts j. It is fixed at .

However, although the above-mentioned protective material is easy to install, it creates a gap and is unstable to fix.Furthermore, since it does not follow the cylindrical shape and is thin, it may be susceptible to collisions with objects to be processed. It has the drawbacks of being easily worn from the outside, having a short durability life, and falling off.

The present invention has been made in view of the above, and the frame protection material is made of a rubber liner having a substantially U-shaped, semicircular, or L-shaped cross section, and end portions on both sides of the rubber liner. It consists of a fixed piece embedded with a rubber liner and a fastening fitting installed between the fixing pieces on both sides, and a rubber liner is attached to the surface of the frame, the fastening fitting is tightened, and the protective material is fixed to the frame. The purpose of the present invention is to provide a frame protection structure that can be used in a sieve device or the like designed to reliably protect the frame.

EMBODIMENT OF THE INVENTION Hereinafter, the structure devised by this invention will be explained about an Example based on drawing.

<Example 1> As shown in FIGS. 1 to 4, 1 is a base frame of a sieve device 20, with a support frame 5 for a sieve screen 4 at the upper part between the side plates 3, and a reinforcing frame 6 at the lower part.

It is in close contact with the lower surface of the reinforcing frame 8b.

. Next, the operation of protecting and attaching the material 10 will be explained.

First, the rubber liner 11 is inserted into the reinforcing frame 8b from above.

At this time, the rubber liner 11 is temporarily fixed in close contact with the outer surface of the reinforcing frame 8b by slightly expanding both sides 11a using rubber elasticity.

After that, the tightening bolt 16 is inserted through the bolt hole 15 of one of the fixing pieces 1.2, and after the pipe rubber 18 is inserted, the tightening bolt 16 is inserted into the bolt hole 15 of the other fixing piece 12. Insert it into Natsu 1
7 and fix the protective material 10, reinforcing frame, 8b
Cover both sides and the top of the container to protect it from collisions with processing objects.

<Embodiment 2> In this embodiment, as shown in FIGS. 5 and 6, the reinforcing frame 19 is cylindrical, and a protrusion 20 having a bolt hole at the bottom is used.
On the other hand, the rubber liner 22 of the protective member 21 is formed to have a substantially semicircular cross section.

Both side edges 22a of the rubber liner 220 are formed thickly,
The inner edge interval is configured to be slightly smaller than the width (outer diameter) of the reinforcing frame 190.

The fixing piece 23 has a flat plate part 23a having a through hole 24, a flange part 23b1, a cylindrical part 23c, and a threaded part 23d connected in this order, and the upper half of the flat plate part 23a, flange part 23b, and cylindrical part 23c forms a side edge. It is embedded and fixed in 22a.

Cover and protect half of the road of 9.

Note that the flat plate portion 23a of the fixing piece 23 in this embodiment does not necessarily need to be formed.

The rest is the same as in Example 1.

<Embodiment 3> □ ゛In this embodiment, as shown in FIG.
1a and the vertical part 31b into an L-shape, and the vertical part 3
The lower part of 1b is a threaded portion 32.

The fixing piece 31 has a horizontal part 31a and an upper part of the vertical part 31b embedded in the rubber liner 22, and the horizontal parts 31a of the fixing pieces 31 on both sides are bent in the direction facing each other (inward), so that when tightened, When it is pulled, a reaction force is received within the rubber liner 22, and due to the reaction force, the tightening is sometimes tightened inward.

The rest is the same as in Example 2. In addition, each Example 1. a,
3 describes the sieving device 2, but it can be similarly applied to the frame such as the upper part of the Iri hopper of the present invention, and the rubber liner is made thicker at the part where the processed material collides than other parts. It may be formed.

Furthermore, canvas may be attached to the inner surface of the rubber liner to provide it with a high tensile strength.

Furthermore, the rubber liner may be formed to correspond to the cross-sectional shape of the frame, and may be formed into a cross-sectional shape.

As described above, according to the present invention, the frame protection material is composed of a rubber liner, fixing pieces whose ends are embedded in both side edges of the rubber liner, and a fastening fitting installed between the both side fixing pieces. In addition, since the protective material can be attached closely along the surface of the frame, the frame can be reliably protected from the processed material, and the work of replacing the protective material can be easily done, making the work easier. This significantly improves performance.

Furthermore, by making the distance between both side edges of the rubber liner smaller than the width of the frame, the rubber liner itself can be provided with a tightening force, making the fixation more reliable. On the other hand, if the tightening fittings are made up of a tightening bolt, nut, and pipe rubber, the tightening port will not come into direct contact with the frame, which will prevent frame wear and at the same time, provide the cushioning effect of the pipe rubber. It is also something that can be demonstrated.

In addition, by making a through hole in the embedded part of the rubber liner in the fixing piece, the adhesive area becomes larger, the adhesive strength improves, and the resistance against pulling out as well as the shear force of the rubber increases. By bending it into an L-shape, the tightening force can be further improved.
