Description

[Detailed description of the device]

[0001]

[Industrial applications]

  This proposal relates to a repulsion plate used for an impact crusher for crushed stone. .

[0002]

[Prior art]

  Conventionally, a rotating disc is provided on the upper end of an upright rotating shaft provided in a machine box, The bases of a plurality of impactors are loosely supported on the outer periphery by upright pins, and a large number of them are arranged along the outer periphery. An impact crusher with repulsive square bars arranged in parallel was used.

[0003]   Each of the large number of repulsive angle bars (30 or more) has a heavy weight (20 to kgf). However, the replacement work and the upside-down work are performed manually, which requires a long time and is a heavy labor. There was a problem that it was working, and the crushed fragments released outside from the gap between the repulsive square rods There was a problem that the casing was broken due to.

[0004]

[Problems to be solved by the device]

  The idea is to hang up a small number of repulsion plates with a hoist and attach / detach them in a short time or turn them upside down. However, there is no risk of crushed pieces being released to the outside, and it is stable during mounting work. The purpose is to obtain the impact crusher repulsion plate.

[0005]

[Means for Solving the Problems]

  To achieve the above objectives   Multiple convex and concave stripes are formed alternately on the inner surface of the arc-shaped plate in the direction parallel to the center line of curvature. An impeller having side surfaces facing the side surfaces of the adjacent arc-shaped plate on both sides of the arc-shaped plate. Repulsion plate of ct crusher   The above-mentioned invention is characterized in that the opposite side surfaces are obliquely intersected with the diametrical direction passing through the center line of curvature. Impact crusher repulsion plate   An arcuate support step is formed on both end surfaces of the arcuate plate, and the support step is formed into a cylindrical support ring. Of the impact crusher according to the first or second invention, which is formed so that it can be fitted into Repellent board   In the first, second or third invention, the arc-shaped plate can be inverted in the direction of the center line of curvature. Impact crusher repulsion plate listed   The above-mentioned first, second, third or fourth invention in which a suspension projection is provided on the outer surface of an arc-shaped plate is provided. Impact crusher repellent plate listed   Composed by.

[0006]

[Action]

  In this proposal, a cylindrical support ring 8 provided inside the impact crusher casing 10 is used. Along the ring 8 by fitting the arcuate support step 7 at the lower end of the arcuate plate 1 which is erected upright Then, a plurality of arc-shaped plates 1 are sequentially placed to form a cylindrical shape as shown in FIG.

[0007]   When mounting, the opposite side surfaces 5 and 5'on both sides of the arc-shaped plate 1 are paired with each other. The facing side surfaces 5 ′ and 5 ′, which are adjacent to each other when facing the facing side surfaces 5 ′, 5 ′, intersect the diametrical direction obliquely. And the arcuate support steps 7 are supported, so that they fall inward. Prevent.

[0008]   Also, the upper cylindrical support ring 8'is fitted to the arcuate support step 7 of the arcuate upper end surface 6. This prevents the plurality of arc-shaped plates 1 from falling inward.

[0009]   The plurality of circular arc-shaped plates 1 erected in a cylindrical shape (the state is shown in FIG. 1) are The uneven lines 3 and 4 are worn, but this wear is unevenly distributed in the upper part. Therefore the upper circle Remove the cylindrical support ring 8'and hook the suspension projection 9 on the outer surface of the arc-shaped plate 1 with a chain. And hoist it with a hoist and turn it upside down to lower the arc-shaped plate 1 to its original position and wear it. The part without can be placed on top.

[0010]

【Example】

  On the inner surface of the arc-shaped plate 1 made of casting, 5 to 6 chevron projections are formed in the direction parallel to the center of curvature c. 3 and the valley-shaped concave streak 4 are formed alternately. The arc-shaped plate 1 has an opening angle of about 60 degrees, It has a width that divides the circumference into six equal parts.

[0011]   On both sides of this arc-shaped plate 1, side surfaces 5'of adjacent arc-shaped plates 1 arranged on the above-mentioned circumference. Side surfaces 5 and 5 ′ facing 5 and 5 ′ are formed. The facing side surfaces 5 and 5'are straight lines of the circumference. It intersects with the radial direction. As shown in Fig. 3, it is recommended that the diagonal directions be almost the same. However, it does not matter in the opposite direction.

[0012]   An upright fixed hook 12 provided on a machine case 10 is engaged with the central portion of the outer surface of the arc-shaped plate 1. A horizontal hook 13 is provided, and the suspension projections 9 and 9 are provided at both upper corners of the outer surface, and the lower both projections are provided. Protrusions 9 and 9 for suspension are provided at corners at symmetrical positions upward, and the protrusions 9 and 9 for suspension are hoisted. Or it can be hung by a crane.

[0013]   Arc-shaped support steps 7 and 7 are formed on the arc-shaped end faces 6 and 6 of the arc-shaped plate 1 respectively. The support step 7 at the lower end is fitted to a cylindrical support ring 8 provided in the lower part of the machine casing 10 with a thing. The upper circular cylindrical support ring 8'is fitted to the upper circular arc-shaped support step 7 to form a plurality of supporting members. The upper end of the cylindrical repulsion plate 11 formed by the circular arc-shaped plate 1 is fixed (see FIG. 1, See FIG. 2).

[0014]   Opposing side faces 5 and 5'are parallel to the curvature center line c and the arc-shaped plate 1 is turned upside down ( It can be used by reversing in the direction of the curvature center line c). But opposite sides 5, 5 ' Does not necessarily have to be parallel to the center line c, and the adjacent arc-shaped plates 1 and 1 are trapezoidal. Then, they can be arranged alternately.

[0015]   Reference numeral 14 in the drawing indicates a material inlet provided at the center of the upper end of the machine case 10, and 15 indicates a rotation. Disc, 16 is a striker, 17 is an upright support shaft of the base of the striker 16, and 18 is a rotating shaft. Bearing housing.

[0016]

[Effect of device]   Since the present invention is configured as described above, the arc-shaped plate is installed in the impact crusher machine box 10. 1. A small number of repulsion plates 11 by 1 can be quickly replaced by a hoist or the like and turned upside down. Not only the safety, but also the stability of the arc-shaped plate 1 during replacement and reversal work. There is a benefit that can secure the nature.   Further, there is no fear that the crushed pieces will be released to the outside of the repulsion plate 11, and the machine box 10 may be damaged. I don't have it.
