The above is an example of the general shape of the horizontal hammer crusher, but there are many other shapes. For example, the one in which the supply port 2 is provided in the upper center or the upper side, the one in which the inspection cover 13 is provided on both sides or the side 11 of the side surface 12, and the great bar arranged in an arc shape have one end of the arc attached to the rotor spindle. 3 and the other end is disposed below the horizontal plane, or only one end of the arc is disposed above or below the horizontal plane of the rotor spindle 3. Further, as shown in FIG. 3, the shape of the great bar 5 is not only a box shape including a curved plate portion having a large number of regularly-perforated square holes 50 and a leg portion provided under the curved plate portion, but also a horizontal shape. A method in which a large number of protrusions are provided in a comb shape on both sides or one side of a rod, and the protrusions abut each other between adjacent great bars to form a desired outlet gap is often adopted.

[0005] Only the crushed material that has been crushed to a particle size smaller than the gap between the square hole and the exit gap is discharged downward through the gap and collected as a product. Crushed material is supply port 2
When it is supplied from the crushing chamber R, it collides with the hammer 4 at the tip of the rotor disk 31 rotating at high speed in the crushing chamber R, and is repelled and crushed by the impact energy. The repelled crushed object draws a line of action formed by the direction of the received energy and its own weight, scatters downward, and collides with an arc surface formed on the top surface of the great bar.

In recent years, there has been a remarkable tendency to improve the crushing efficiency of a horizontal hammer crusher as well as other models. In order to reduce soaring labor costs, it is necessary to increase the efficiency of the apparatus and suppress production costs. It is a time when it does not become. Naturally, it is of the utmost demand to increase the speed or increase the size of the device, and improvements regarding various parts of the horizontal hammer crusher have been proposed and implemented.

With the aim of improving the productivity of the horizontal hammer crusher, the hammer, which is the main element of the crushing action, naturally becomes more severe than before, and there is a need to improve the material properties in order to improve the wear resistance. Many have been proposed. There have also been provided some improvements in the shape of the hammer that are advantageous for replacement with new ones after the wear. However, the wear is not merely caused by the hammer, but all surfaces inside the crushing chamber R formed in the casing are subjected to the collision of the crushed objects which are repelled and scattered with the rotation of the rotor. Is unavoidable, even to varying degrees.

The great bar forms a curved surface that is closest to the locus drawn by the hammer mounted on the rotor disk at a high speed, and is opposed to the bar. The crushed object collides with a repulsion plate or the like on the inner surface of the casing. Since it corresponds to an outlet that passes through the gap and is discharged to the outside of the crushing chamber, the crushed material having a high hardness always passes while colliding or rubbing, so that the wear of the crushed material is not necessarily small. As the wear of the great bar progresses, the area of the open voids increases and the particles pass through and discharge large particles of a predetermined particle size or more. This amplifies the error in the particle size distribution of the product, and if left as it is, this tendency is further exacerbated. Then, since it may eventually cause a quality defect, checking the progress of wear and properly updating are one of the important items in work management.

However, the replacement of the great bar has conventionally been a complicated and extremely difficult operation for the operator, and has been one of the difficulties in maintenance. As shown in FIG. 4, the replacement method of the worn great bar is as follows. The inspection cover 13 provided in the upper half of the casing 1 is opened to open the crushing chamber R, and as shown in FIG. Usually, they are lifted and carried out one by one. The great bar 5 is fitted into a concave groove 18 formed between the upper guide 16 and the lower guide 17 which protrude in an arc shape on the inner surface of the side surface 11 of the casing 1.

FIG. 5 is a view taken along the line Y--Y in FIG. 3 (A), showing the state of the conventional great bar 5a fitted between the upper and lower guides. FIG. 6 is an XX development view of FIG. 3 (A). This is a state in which the conventional great bar 5a is attached, and is also a view showing the problem of the present invention. As shown in the figure, a gap c is provided between the side surface 11 of the casing 1 and the side end surface 54 of the great bar 5a facing this surface. Great bar material is made of high-hardness wear-resistant material such as high-manganese cast steel to extend its useful life. Therefore, precision finishing by machining is difficult, and distortion and length during casting are naturally difficult. It is a fact that some gaps are unavoidable in order to absorb the allowable error. However, due to the presence of the gap c, a large amount of crushed dust, fine powder, and the like enter therein during operation, and vibrations, collisions, swings of the great bar, and the like are spurd and condensed to change into a solidly aggregated sedimentary layer P. . Therefore, once such a strong deposited layer P is formed, even if an attempt is made to slide inside the groove formed by both guides to replace the great bar, the gap c
The stiffness makes it hard to move even with a small blow, making its removal extremely difficult. Even inspection cover 1
Even if one of the three near can be removed, the next great bar will be less workable, the difficulty of unloading will increase further as it goes in, and it will be extremely alarming for managers in terms of workplace safety. There is a problem that it frequently occurs.

FIG. 1 is a development view of a great bar according to a first embodiment of the present invention, which corresponds to FIG. 6 of the prior art.
In the figure, 5A is a box-shaped great bar composed of a curved plate portion 55 having a large number of square holes 50 and legs 56 provided below the curved plate portion 55. Both sides of the great bar 5A oppose the side surface 11 of the casing. The end is provided with an inclined surface 51A that increases toward the carry-out side. Therefore, a tapered gap C is formed between the side surface 11 of the casing and the inclined surface 51A. The great bar 5A may have a structure without the legs 56, or may have a round hole or a slit instead of the square hole 50.

In FIG. 1 or FIG. 2, a large amount of crushed dust, fine powder, and the like enter into the tapered gap C during operation.
Vibrations, collisions, swings of the great bar, and the like are also spurred, and the sedimentary layer P changes into a solidified and firmly aggregated layer P. For this reason, unless the inclined surface is provided on both side surfaces of the great bar, in order to replace the great bar, it is attempted to slide in the concave groove 18 formed by the upper guide 16 and the lower guide 17 as shown in FIG. However, since the gap is tight, it does not move even if given a small impact, making it extremely difficult to remove it. Even if one near the inspection cover 13 can be removed, the next great bar will be less workable and the difficulty of removal will increase as it goes in. However,
Since the great bar of the present invention has inclined surfaces on both side ends, if a slight impact is applied, the edge of the deposited layer that has stayed between the tapered gaps C is easily cut off, which induces the action of easily detaching the great bar. I do.
