DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. FIGS. 1 and 2 show a first embodiment, in which a bulky object crushing apparatus 1 comprises a pair of upper crushing rollers R1 and R2 in a housing 2 having upper and lower openings similarly to a known structure.
And a lower crushing roller R3 located thereunder,
Primary crushing is performed by the upper crushing rollers R1 and R2, and then crushing is performed again by one of the upper crushing rollers (for example, R2) and the lower crushing roller R3.

The housing 2 is divided into an upper housing 3 and a lower housing 4. The upper housing 3 is composed of a fixed frame 5 and a movable side wall 6. The upper housing 3 and the lower housing 4 have the same structure on the left and right, and only one of them will be described below. The movable side wall 6 includes a movable liner 7, a support frame 8 for supporting the movable liner 7, and a transition member 10 of the support frame 8. Transition member 10
A guide rail 11 attached to the fixed frame 5, a traveling frame 12 traveling on the guide rail 11 and attached to the support frame 8, a drive chain 15 for driving the traveling frame 12,
It comprises the chain drive motor M, the guide sprocket 16 and the driven sprocket 17 attached to the traveling member 12.

As shown in FIG. 2, the movable side walls 6 are provided on the left and right sides of the case except for the central portion to maintain the strength of the side walls. The traveling member 12 includes a knock pin 18. The knock pin 18 is operated by, for example, a solenoid, and is inserted into a fitting hole formed in a fixed plate 19 attached to the fixed side wall 6 by inserting the knock pin 18.
The movable side wall 6 is fixed at a predetermined operating position.

The other structure is the same as that of the known structure, and the same parts are denoted by the same reference numerals and description thereof will be omitted.

In the above configuration, when the crushed material accumulates in the vicinity of the upper crushing rollers R1 and R2, or when a difficult-to-crush iron lump or the like is accidentally thrown in, the foreign matter is discharged by the knock pin 18.
The chain 15 is driven by the operation of the drive motor M to move the movable side wall 6 through the traveling member 12 to the guide rail 1.
The position is shifted to the position indicated by the chain line in FIG. Thus, the upper part of the housing is opened, and the crushed material and the iron lumps that are difficult to crush, which have accumulated near the upper crushing roller, can be easily removed.

After the removal of the object to be crushed is completed, the movable side wall is returned to the predetermined operation position by the traveling member 12, and the knock pin 18 is fitted and fixed to the fixed plate 19 to be fixed and held at the predetermined operation position.

Further, the accumulation of crushed materials and the entry of foreign matter such as iron ingots are detected from the loads on the rollers R1, R2 and R3,
The housing may be automatically opened by the above operation, and the crushing roller may be rotated reversely to discharge the foreign matter.

FIG. 3 shows a second embodiment. The casing 21 of the bulky object crushing apparatus 20 of the present embodiment includes an upper side wall 22 and the lower side wall 4. The upper side wall 22 has an opening 24 at its lower part, and is provided with a slide plate 25 for shielding this.
Reference numeral 26 denotes an elevating cylinder of the slide plate 25. The other structure is the same as the previous example, and the description is omitted.

In the above configuration, when the crushed material accumulated in the housing is taken out, the opening 24 is opened by lifting the slide plate 25 by the lifting cylinder 26. Thereby, it is possible to take out the crushed material and the hard-to-crush iron lump and the like accumulated in the housing.

FIG. 4 shows a third embodiment. In the figure, the bulky object crushing apparatus 30 shows an example in which an upper side wall 32 and a lower side wall 33 of a housing 31 can be partially moved.
That is, the upper side wall 32 is composed of the fixed frame 5 and the movable side wall 6 having the same structure as in the first embodiment. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The lower side wall 33 is provided on the left and right support shafts 3 respectively.
5 and a fixed side wall 37
Knifes N1 and N2 provided opposite to the lower crushing roller R3 are attached to the movable side wall 36, and are transferred together with the knives by the transfer means 40. An example in which the rotation is performed by using the connecting arm 42 is shown. 45 is the fixed side wall 3
7 shows a fixing plate, which also serves to determine the mounting position of the movable side wall 36. When the movable side wall 36 is turned outward,
The height is set so as not to hinder the removal of the crushed material near the crushing roller.

In the above configuration, the upper crushing roller R1,
The removal of the crushed material accumulated near R2 is performed by moving the upper movable side wall 6, and the lower crushing roller R3, particularly when removing the crushed material accumulated near the knife or the iron lumps that are difficult to crush, is used to remove the lower portion. This is performed by moving the movable side wall 41.

Although the above embodiment shows an example in which both the upper and lower sides of the housing are opened, only the lower side wall 33 may be opened together with the knife.

[0026]

As described above, according to the first aspect of the present invention, in the crushing apparatus, when the crushed material accumulates near the upper crushing roller or when the difficult-to-crush iron lump or the like is erroneously thrown in, the crushing device does not detect the crushed material. By removing a part of the upper side wall of the housing as the removing means and attaching and detaching it by the transfer means, the removal can be easily performed. According to the second aspect, instead of making a part of the upper side wall of the casing detachable, a part of the upper side wall is opened, and a slidable shielding plate is attached to the opening. By pulling up the shield plate and removing the accumulated crushed objects, the hard-to-crush iron blocks, and the like from the opening, the crushed objects in the upper part of the housing can be easily removed in the same manner. According to the third invention,
When removing the lower crushing roller, in particular, the crushed material accumulated near the knife, a part of the lower side wall of the housing can be moved, and a knife provided opposite to the lower crushing roller is attached to the side wall. At the same time, by moving the side wall, the accumulated crushed object, hard-to-crush iron lump, and the like can be easily removed. Further, according to the fourth aspect, a part of each of the upper and lower side walls of the housing can be shifted, and a knife provided opposite to the lower crushing roller is attached to the side wall, and the upper side wall is shifted by the shifting means. By moving a part of and / or a part of the lower side wall together with the knife, it is possible to easily remove objects to be crushed, hard crushed iron blocks, and the like accumulated in the upper and / or lower part in the housing.
