A V-shaped sand lump inlet is formed between them, and a V-shaped crushing portion is formed between the swing-side blade of the swing blade device and the fixed-side blade of the fixed blade device. You. That is, a double V is formed between the V-shaped sand block inlet and the V-shaped crushing portion.
A Z-shaped zone is configured (FIG. 7). This double V-shaped
The sand mass generated by the foundry that has been charged into the sand is first pressed and crushed between the fixed plate and the rocking plate of the sand mass inlet, and the crushed sand mass that has been primary crushed to a predetermined size is When it falls and reaches the crushing section, it is stopped between the blades, and the drop is stopped.

Through the bypass crushing space formed between the blades, the fall is stopped in a state of being stopped between the next blades. Thereafter, the detour crushing space B between the next blades is further narrowed by the extension of the piston rod, and at the same time, the crushed sand mass between the blades is further pressed and crushed by the unevenness between the blades, and further crushed to a predetermined size. Turned into crushed blocks that are subdivided into dimensions. Thereafter, the same operation and crushing operation as described above are repeated, and the crushing flow passage B1 formed by the fixed-side blade and the oscillating-side blade sequentially flows down to a reusable approximately 150 mm square to 300 mm square. It is crushed and discharged out of the device through a crushing block discharge port formed by the fixed blade device and the swing blade device.

こともあり得る。In a situation where the sand mass is larger than necessary and cannot be crushed, the control is automatically performed.
That is, since excessive pressure is applied to the oscillating-side blade, the control is controlled so as to temporarily stop the advance of the piston rod of the cylinder. Specifically, the swing-side blade is retracted once, and then swings forward again, which is a structure for avoiding a failure of the device and efficiently and reliably breaking the device. Of course, this control may be performed automatically.

に破砕できる。According to the present invention, there is provided a fixed-side blade provided with a half-cut-shaped blade provided on a frame in a staggered manner, and a half-cut-shaped blade having a fitting relationship with the fixed-side cut-shaped blade. Oscillating-side blades in which staggered blades are arranged in a zigzag manner, and pressing the upper side of the oscillating-side blades to apply a large crushing force and breaking force to the oscillating-side blades, which are produced in a foundry. This is a structure in which a sand block is crushed to form a crushed block subdivided into a predetermined size, and then guided to a discharge port through a natural fall through an inclined fall passage. Therefore, the lattice-shaped bypass crushing space formed between the semi-cut-shaped blades and the fitting relationship by the semi-cut-shaped blade can be used, and the sand lump generated in the foundry can be reduced by this effect. It can be crushed reliably, simply and quickly.

ある。The present invention is an upward pressing system in which a piston rod of a cylinder is pivotally mounted above an oscillating blade device opposed to a fixed blade device, and cooperates with a half bowl-shaped blade and its fitting relationship. It is a configuration by action. Therefore, not only the large crushing force and breaking force with a small operating force, but also useful for crushing all sand lumps, or the rocking blade device is not displaced by the input amount or size of the sand lumps, it is reliable and reliable. It has excellent effects such as functioning smoothly and being useful as an optimal recycled casting material from the crushing subdivision. Further, the pressing force of the cylinder can be sufficiently transmitted to the rocking plate, and a large crushing force and a crushing force can be imparted to the rocking-side blade, which is useful as a sand crushing device.
