[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a casting weir, a runner, and a crushing / breaking device for defective products , which have become unnecessary by utilizing hydraulic pressure and natural fall.

[0002]

2. Description of the Related Art Conventionally, this type of casting weir, runner, defective
As a device for crushing an unnecessary product of a product (hereinafter, simply referred to as an unnecessary product), a device having the following configuration is generally used. That is, through a pressing means such as a cylinder,
It is composed of a moving knife device that moves forward and a fixed knife device that faces the moving knife device, and is configured to crush unnecessary products through a constant surface pressure of the moving knife device that moves forward.

As a technical document which has the same structure as the above-mentioned structure, there is, for example, a crushing device disclosed in Japanese Patent Laid-Open No. 60-241939. A pressing member having a blade and a front wall (fixing member) having a plate-shaped receiving blade that fits with the pressing blade of the pressing member are provided, and unnecessary products are crushed by the pressing force and the receiving blade. It is configured to fall into. However, in the present invention, the fitting relationship between the plate-shaped pressing blade and the plate-shaped receiving blade is only in the vertical direction.

Another crushing device has a structure usually called a shreter. The gist of the device is that a drum with a hammer is rotatably supported in a casing equipped with a shooter, and the hammer and the impact are struck. It is configured to be crushed by using an impact with a piece (a liner or a damper with a liner).

[0005]

In the conventional crushing device and the prior art documents described above, since the moving blade device is structured to move forward in the horizontal direction, a large lump is formed in the unnecessary product. If there is, or if there is a long columnar, etc., an abnormal load is applied to a part of the movable blade device, the movable blade or the blade frame tilts, and sufficient crushing cannot be performed, workability It is possible that there are problems such as a bad condition and a device failure.

In particular, in the above technical literature, a plate-shaped pressing blade,
Fitting relationship of the plate-shaped receiving blade, because only the vertical direction, the operation of the pressing member, it requires a great power and efficient crushing can not be expected, also Oridan the Ru hardly impossible der
At the same time, in the crushing device for castings of this kind into which unnecessary products of various sizes are put, this is a process that occurs occasionally, and the present inventor often observes it.

As a similar technical content, a hydraulic cylinder

In the above-mentioned conventional crusher, in the case of this kind of heavy unnecessary product, the load on the drum becomes large, there is a structural problem, or the wear of the hammer, liner, etc. is severe, It is a place that cannot be put to practical use.

[0009]

Therefore, according to the present invention, an unnecessary product having various shapes, materials, and forms having a heavy weight can be crushed and broken surely and with one touch, and the optimum size and weight for a cupola or an electric furnace can be obtained. And swinging the swinging blade device

And a slanted fall passage .

[0011]

The function of the present invention (the condition of crushing and breaking) will be described below.

As shown in FIG. 2, the oscillating plate and the oscillating blade (hereinafter, in principle, the oscillating plate and the oscillating blade) constituting the oscillating blade device contract the piston rod of the cylinder. In the state of the retreat limit, the swing plate and the swing side blade, and the fixed plate and the fixed side blade constituting the fixed blade device (hereinafter, in principle, the fixed plate and the fixed side blade). A large opening is formed between and.

However, it is provided at the lower end of the swing side blade,
Moreover, the belt-shaped blade provided at the lower position of the fixed-side blade is configured to close the lower portion (the discharge port) of the opening portion, and the belt-shaped blade exactly constitutes the bottom surface. For example, a long blade is simple. It has a structure in which a rod-shaped object, a runner, and the like having various shapes can be reliably positioned between the swing-side blade and the fixed-side blade.

As described above, in the state where the large opening is formed, the unnecessary products are sequentially introduced from the opening. In this case, as described above, since the strip-shaped cutting tool is provided on the bottom surface of the opening, it is assumed that the swivel-side cutting tool and the fixed-side cutting tool have slipped between the staggered cutting tools, for example, the long tool. Even a rod-shaped object or a runner can be held by the band-shaped blade.

When a predetermined amount of unnecessary product is put into the opening , the piston rod of the cylinder is extended,
When the swing-side tool is moved forward, the opening formed by the swing-side tool and the fixed-side tool is gradually narrowed from the lower side, and first, the lower tool is fitted into each other to fit into each other. is, in a mountain-shaped end face of the chevron-shaped blade, but continue to crushing or Oridan the in many fields manner each of the required product, this time, the
In the invention, the pivoting position of the piston rod is such that
Since it is above the table, the pressing force of the cylinder is sufficient.
It is transmitted to the rocking plate and becomes a mountain-shaped tool on the rocking side.
A large crushing / breaking force is applied to reduce the size of unnecessary products.
Irrespective of, reliable and smooth crushing and breaking can be performed.

On the other hand, above the opening, since the above-mentioned mutual fitting relationship between the swing side blade and the fixed side blade is not established, mainly the swing side blade and the fixed side blade and their respective blades. Through the approach (compression) with the table, for example, the large unnecessary product in the portion is broken.

In this way, above the opening, a large unnecessary product that has been thrown in is broken, and the unnecessary primary products that have been subdivided by the breaking work are then shaped into a mountain shape that is in a fitting relationship. Secondary processing, that is, crushing and breaking work, is performed between the blades, and is further subdivided.

As described above, the sloping falling passages formed by the end faces between the blades which are subdivided and have a mountain shape (hereinafter
Below, let's just use the fall path. Unprocessed unnecessary products which have become ready to pass through (1 ) sequentially pass through the drop passage and naturally fall toward the discharge port due to their own weight. Therefore, the processed unnecessary products that cannot pass through the drop passage are
When it cannot fall naturally toward the discharge port, and in such a state (the same applies when unnecessary products become lumpy), for example, when more pressure is applied to the rocking side blade, the piston rod of the cylinder advances. Is a control mechanism for stopping, specifically, the swing-side tool device is once retracted and then is swung forward again.

After that (the above-mentioned normal time), when the oscillating side blade is further advanced, for example, as described above, the secondary-processed unnecessary product is further crushed and broken, and further divided into smaller pieces. At this time, as described above,
The pivot position of the piston rod is pivoted above the swing blade device.
Therefore, the pressing force of the cylinder is sufficiently oscillated.
It is transmitted to the moving plate and the size of the rocking side tool is increased to a mountain-shaped tool.
Crushing / breaking force is applied, and it is related to the size of the unnecessary products.
Without, it can crush and break reliably and smoothly. did
Therefore, it is more reliable and subdivided, and this subdivision
The unnecessary product that has undergone the tertiary processing is naturally dropped toward the discharge port as described above. Such crushing and breaking operations are repeated, and as the oscillating side cutter approaches the forward limit, the normally subdivided normally processed unnecessary products gradually fall.

Then, the final processed unnecessary product slides down the inclined surface of the strip-shaped blade and is discharged to the outside of the apparatus through the discharge port. Normally, the unnecessary product is thrown in when the swing-side blade reaches the forward limit. Almost all of the products are subdivided into specified dimensions,
Most of them are discharged from the device through the discharge port. In addition, some of the subdivided unnecessary products that remain between the mating blades are
All are discharged by retracting the swing-side blade at the forward limit. After that, the rocking-side knife retreats through the contraction of the piston rod of the cylinder, and when it reaches the retreat limit, the opening becomes an enlarged opening and returns to the initial state.

The lower half of the fixed blade device is constructed so that it can be moved toward and away from the swing blade device via a pressing device, and is fixed when it moves (swings). (Thus, in the present invention, the fixed blade device is fixed over time.) Using this fixation over time, for example,
It has a structure that can cope with the size of the unnecessary products to be thrown in, or the size of the unnecessary products subdivided.

Specifically, when the regulating plate is moved up and down through a pressing device, in this example, a nut is screwed in or unscrewed, and, for example, the regulating plate is lowered, almost the lower half of the fixed blade device is When it swings clockwise in 1 and raises the regulating plate, almost the lower half of the fixed blade device returns to the original position,
As shown in FIG. 1, it is configured to return to a substantially drooping state.
