のである。BRIEF DESCRIPTION OF THE DRAWINGS FIG. Reference numeral 1 denotes a bucket, which is attached to the tip of the operation arm 3 of the civil engineering machine 2. A pair of right and left rotating shafts 4 and 5 are supported in the bucket 1, and spur gears 6, 6 and 7 and 7 shown in FIG. Hydraulic motor 10, 1
1 and rotate in opposite directions. Rotary axis 4
A plurality of crushing tooth plates 12 are fixed to the
3 is fixed in the same number. The crushing tooth plate 14 of the illustrated embodiment forms a recess 15 between the three arc-shaped crushing teeth 14, and the crushing tooth plate 12 of the rotating shaft 4 is crushed by the crushing tooth plate 1 of the other rotating shaft.
3 is shown as opposed to the recess 15, but the spacing between the rotating shafts 4 and 5 is changed, or a small crushed tooth is attached to the tooth plate to prevent the teeth from entering the recess 15. Sometimes they are used. The crushing teeth 14 of the crushing tooth plates 12 and 13
A square tooth 16 is formed at one end and a sharp cutting blade 17 is provided at the other end. When the rotating shafts 4 and 5 rotate inward each other (see FIG. 4), the square teeth 16 and 1 of the crushing tooth plates 12 and 13 are rotated.
The concrete mass K is destroyed in 6 and the finely crushed mass is discharged to the outside through a drop port 19 provided at the bottom of the bucket 1. When the rotary shafts 4 and 5 are turned outwardly as shown in FIG. 5, the large concrete mass K hits the outer peripheral surface of the bucket and is stabbed and broken by the sharp piercing blade 17, and the small mass K is divided into two crushed tooth plates. It is guided between 12 and 13 and crushed by the sharp piercing blade 17. In the present invention, in order to prevent the concrete mass K from flying up at this time, the holding plate 20 is connected to the shaft 2.
1, the operation arm 3 and the holding plate 20 are connected via the connecting rod 22 so as to be openable and closable above the bucket 1, and the operation arm 3 is moved to open and close the holding plate 20, thereby continuing the crushing operation smoothly. It is like that. Various ideas for operating the holding plate 20 are conceivable as shown in FIG. FIG. 5 (I) shows that a ridge 30 is protruded from the outer surface of the holding plate 20, and the ridge 30 is pressed by the base of the operating arm 3 to be pressed down.
Normally, the presser plate 20 is urged upward by a spring 31. FIG. 5 (II) shows that a hydraulic cylinder 33 is interposed between the bucket 1 and the presser plate 20 to utilize hydraulic pressure. The holding plate 20 is moved. 5 (III), the holding plate 20 is pivotally attached to the base of the operating arm 3 with the pin 35, and the holding plate 2
FIG. 2 shows a state in which the receiving tool 36 integrated with the reference numeral 0 contacts the operation arm 3 to operate the presser plate 20 with the operation arm 3. Further (IV)
Attaches the holding plate 20 to the base of the bucket 1 with a pin 38. The pin 38 is connected to a middle rod 40 connected to the tip of the hydraulic cylinder 36 by a pin 37 via a connecting rod 39 with the pin 37, and the pins 37, 38 are supported. The holding plate 20 opens and closes.
