DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing / cutting machine capable of extremely efficiently cutting and dismantling a structure such as a tank made of a metal plate such as an iron plate or a waste iron plate.

[0002]

2. Description of the Related Art In recent years, various crushing attachments have been developed for further finely cutting remnants such as reinforcing bars, steel frames, pipes, etc. from dismantled reinforced concrete or steel structures (such as buildings). Many of them are very suitable for crushing concrete blocks or cutting reinforcing bars, steel frames and the like. However, there are few suitable ones for dismantling structures such as tanks and towers made of iron plates and the like.

[0003]

As described above, in the dismantling of structures such as tanks and towers made of an iron plate or the like, the iron plate is cut while being cut.
Such a conventional crusher is not suitable for cutting an iron plate. In a conventional type of crusher, the crushed material is crushed by opening and closing two crushing parts, and the crushed material is crushed by applying pressure from up and down or right and left directions. Lumps and reinforcing bars are cut into small pieces by a cutting blade attached to the crusher. Such a cutting blade is for crushing a reinforced concrete block and cutting an internal reinforcing bar. Therefore, it is not suitable for cutting a face plate such as an iron plate.

[0004]

The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, the present invention has provided a fixed jaw main body and a movable jaw main body in an outer casing so as to be freely opened and closed. At one end in the width direction of the fixed jaw main body, a rising portion to which a fixed cutting blade is attached is formed along the longitudinal direction of the fixed jaw main body. A rising portion is formed, an appropriate interval is provided between the rising portion and the tip rising portion, a fixed jaw-side projection is provided at a tip portion of the rising portion and the tip rising portion, and a tip of the movable jaw body is provided at a tip of the movable jaw body. A movable jaw-shaped projection in the form of a wedge that gradually becomes thinner as it moves toward the front, and a movable cutting blade provided along the longitudinal direction of the movable jaw main body, wherein the movable jaw-side projection has a rising portion and a distal end of the fixed jaw main body. So that it passes through almost the middle of the rising part, By using a crushing and cutting machine configured to be able to shear with the fixed side cutting blade and the movable side cutting blade, it is possible to efficiently dismantle structures such as tanks and towers made of iron plate etc. It is possible to solve the above problem.

This is an embodiment in which the cutting edge surfaces 8a and 10a are straight and flat. In this embodiment, the surface of the rising portion 5 is formed to be linear and flat. The tip rising portion 6 has the same shape (including substantially the same shape) as the tip rising portion 6 of the first embodiment.

[0013]

The crushing and cutting machine of the present invention is mounted on a boom 21 of a construction vehicle 20, as shown in FIGS. Then, a structure 22 such as a tank constituted by a plurality of iron plate materials
The work of cutting the iron plate T that constitutes is performed. Figure 1
As shown in FIGS. 0 to 12 and the like, the iron plate T is set between the fixed jaw main body 2 and the movable jaw main body 3 of the crushing and cutting machine.

Next, a state where the iron plate T is cut by the fixed-side cutting blade 8 and the movable-side cutting blade 10 while being clamped and fixed by the fixed jaw-side projection 7 and the movable jaw-side projection 9 is shown in FIGS. It will be described based on. Here, FIG. 13 shows the step of cutting the iron plate T as viewed from the side surfaces of the fixed jaw main body 2 and the movable jaw main body 3. FIG. 14 shows that the fixed jaw side projection 7 and the movable jaw side projection 9 bite into the iron plate T, and the movable jaw side projection 9
This shows the process of breaking through. Further, FIG. 15 shows a step of cutting the iron plate T with the fixed side cutting blade 8 and the movable side cutting blade 10.

First, by closing the fixed jaw main body 2 and the movable jaw main body 3, both sides of the iron plate T are fixed by the fixed jaw side projections 7, 7 and the movable jaw side projection 9, as shown in FIG. It is in a state of pressing and holding. At this time, the fixed jaw main body 2 of the crushing cutter is arranged inside the cylindrical structure 22, and the movable jaw main body 3 is positioned outside the structure 22. Next, when the movable jaw main body 3 is closed to the fixed jaw main body 2 side through the cylinder 4, the fixed jaw side projections 7, 7 of the fixed jaw main body 2
Pressing from the inside of the iron plate T of No. 2 and biting [Fig. 13 (B)]
And FIG. 14 (A)], and the movable jaw side projection 9 presses and bites from the opposite side of the iron plate T [see FIG. 14 (B)], thereby stabilizing the work state in which the crushing cutter cuts the iron plate T. . Then, when the movable jaw main body 3 further moves toward the fixed jaw main body 2 side, the movable jaw side projection 9 breaks through the iron plate T (see FIGS. 13C, 14C, and 14D). The iron plate T is easily cut. At the same time, the fixed-side cutting blade 8 and the movable-side cutting blade 10 also start cutting the iron plate T (see FIGS. 15A to 15C). At this time, the operator can also check the disconnected state from the cab of the construction vehicle 20.

As described above, first, in the process of cutting the iron plate T, the fixed jaw side projections 7, 7 of the fixed jaw main body 2 and the movable jaw side projection 9 of the movable jaw main body 3 press and hold the iron plate T. Since the cutting work of the iron plate T by the fixed-side cutting blade 8 and the movable-side cutting blade 10 is performed with a slight delay after biting into the iron plate T, slippage and deviation when cutting the iron plate T are prevented. , It can be in a stable cutting work state.
In addition, the fixed jaw main body 2 is formed only at the front end portion of the fixed jaw main body 2 on the front end rising portion 6 side. Therefore, the fixed side cutting blade 8 and the movable side cutting blade 10
15A and 15B, the cut portion of the iron plate T on the side of the leading edge 6 is the work bottom surface 2 as shown in FIGS.
a, and the iron plate T is cut satisfactorily.

FIG. 16 shows the progress of a cutting line appearing on the iron plate T as the fixed jaw main body 2 and the movable jaw main body 3 gradually close. According to this, first, in FIG. 16A, the fixed jaw side projections 7 and 7 and the movable jaw side projection 9
This shows a state in which the iron plate T is cracked because the movable jaw side projection 9 of the movable jaw main body 3 bites into the iron plate T by pinching and pressing the iron plate T. Next, FIG. 16B shows a state in which the cutting by the fixed-side cutting blade 8 and the movable-side cutting blade 10 has been started. Next, FIG. 16C shows a state in which the cutting by the fixed-side cutting blade 8 and the movable-side cutting blade 10 is completed.
