And so on.

A third aspect of the present invention is a crushing packet for a casting using the crushed casting as an aggregate.

[0017]

FIG. 5 shows an example of the procedure, operation, and the like of overlaying by the coating method for overlaying fixed and movable blades according to the present invention. At least a scooping portion of a packet body and a semi-bowl are shown. Curved crests of fixed and semi-bowl-shaped movable blades,
The tip-side peak and the tail-side peak are built up by using steel welding having physical properties such as hardness, strength, and abrasion resistance. The method of overlaying is intended to improve the hardness and / or strength of the fixed / movable blade. In the configuration in which the lift piece is provided between the fixed and movable blades, the operation is performed also on the lift piece. Then, welding A of a welding material having a low hardness and a low elongation is performed. Welding of welding material with hard intermediate build-up and wear and impact resistance B
do. The upper cladding performs welding C of the super soft material. In addition, this welding is made approximately 11 mm to 17 mm as a whole. Of course, the coating can be replaced with welding A, welding B1, welding B2, and welding C. In addition, welding A is arc welding, welding B, welding B1,
It is preferable that welding B2 is CO2 welding, welding C is arc welding, and welding D is arc welding. Then, after performing the welding A to welding C, a hening effect is given by hitting with a hammer or the like, and the strength of each of the welding A to welding C surfaces is improved and hardened.

Next, an example of crushing will be described. In a state where the movable plate is set at the raised position, the arm is turned downward, and the casting is scooped by using the scooping section in the downward state. After scooping, this time, use the arm to make the packet substantially upward and horizontal, move the movable plate sequentially in this state, and use the engagement (fitting) between the fixed blade and the movable blade to remove the casting. Crush. Specifically, the cutting between the tip-side ridges of the opposed blades, the cutting by the curved ridges of the fixed-side cutter and the movable cutter, or the tip-side ridges, and the butt-side peaks. Breaking and / or crushing through the cutting of the fixed / movable blade by the curved ridge and the break by the rifle piece, or the individual breaking of each of the above-mentioned breaks, or the total breaking by the combination of the breaks, etc. Crushing). By moving the packet sequentially upward while performing this breaking, the shattered crushed casting falls sequentially from the gap between the two blades and is discharged from the discharge port. Therefore, the above operation is repeated for the crushed casting that is not discharged. If necessary, the packet can be moved in the vertical direction or swung in the swiveling direction with respect to the floor, and the movement of the arm and the heavy equipment can be used as necessary. It is also possible to work while moving in the crushing process.
