Description

  The present invention relates to a multipurpose scrap demolition machine suitable for carrying out scrap demolition work of various waste materials such as discarded automobiles, building waste materials, and further pipe waste materials, and in particular, a hydraulic pressure mounted on a self-propelled vehicle so as to be turnable and prone. An operating boom, a scrap dismantling work pen that is opened and closed by a remote operation attached to the tip of the boom, and a pair of left and right working arms that can be driven up and down and that can be opened and closed, provided at the front or rear of the vehicle It is related with the scrap demolition machine provided with.

  Conventionally, scrap scrapping work of scrap cars is done by dropping piled scrap cars one by one on the ground with a crane, holding them sideways with a transport vehicle, cutting them to an appropriate size with a cutting torch etc. at a scrap factory workplace, or The engine parts were being removed.

  In addition, for example, a pair of left and right work arms that can be opened and closed by power are provided at the front or rear of a self-propelled vehicle equipped with a hydraulically operated boom having an opening and closing work penetrator at the tip so as to be able to turn and prone. Various work hands such as a pair of opposing cups for holding the scrap object in a rotatable manner from both sides and a pair of breaking tools for crushing or breaking the scrap object from both sides are attached. There are also known demolition machines (see, for example, Patent Document 1). With such a demolition machine, the efficiency of scrap demolition work is dramatically improved, and it is possible to separate and collect scrap materials by high efficiency. That is true.

  In recent years, not only discarded automobiles but also various other scrap objects such as household appliances such as refrigerators and washing machines, building waste such as reinforcing bars and window sashes, or pipe waste such as water supply pipes and water distribution pipes are usually used. In this dismantling operation, various scrap objects are accumulated in various places and waiting for dismantling. For example, in a discarded electric washing machine, the outer casing and washing tub must be separated from the internal motor by disassembling work, and in the case of an electric refrigerator, the casing and inner heat insulating material and compressor are separated and disassembled. However, with conventional dismantling machines, it is not possible to directly remove these internal motors and compressors with the opening and closing work pen at the tip of the hydraulically operated boom. Processing such as doing was performed.

  Under such circumstances, multipurpose scrap that can efficiently separate and dismantle various scrap objects including scrapped vehicles by expanding the range of handling for separating and collecting scrap objects in terms of size and strength. Dismantling machines are also known (see, for example, Patent Document 2).

Furthermore, pipe waste materials such as water supply and drainage pipes generally have valves connected to the middle of the pipe portion, which means that the dissimilar metal member to be separated and recovered is relatively small and firmly fixed. Such waste materials were difficult to handle with conventional dismantling machines, and in many cases were disposed of without being separated and collected. In this case, the piping portion should be collected and collected mainly as iron scrap useful as a steelmaking raw material, and the valve portion should be recovered as a relatively expensive gunmetal recycling raw material. However, for example, a screw portion of a steel pipe remains screwed and fixed to a socket portion of a gunmetal valve, and if these can be separately collected, it is predicted that the economic effect of material recycling will be further improved.

  In recent years, the trend of recycling resources has increased, and for recyclable raw materials, including scrapped automobiles, construction waste materials, and piping waste materials, can be collected separately with the highest possible quality / component purity rather than landfill waste. Is required. For example, in the dismantling of a reinforced concrete building, the distribution lines stretched around the internal compartments are reused as copper resources, window sashes and partition panel frames are reused as aluminum resources, and handrails and fire doors are reused as iron resources. Is possible. In addition, reinforcing bars in the building frame can be reused as iron resources, and concrete pieces can also be reused as road pavement materials.

Furthermore, pipes used for indoor water supply pipes are iron pipes or steel pipes having a diameter of about 30 to 100 mm, and many of them are connected to valves such as water stop valves. In addition, some of the covered electric wires used for indoor distribution lines have a cross-sectional area of about 400 mm ² , and the core wire is made of high-quality copper. When recycling these pipe wastes and waste wires, it is too thin to handle with the work pens equipped with conventional scrap dismantling machines and difficult to cut, and it is coated to collect and collect high-quality copper materials. Peeling the outer sheath (often made of soft plastic) from the electric wire was also a situation that had to rely on manual work in a separate process.

  An object of the present invention is to solve the above-mentioned conventional problems, and to provide a multipurpose scrap demolition machine suitable for scrap demolition work of various waste materials such as construction waste materials, as well as piping waste materials as well as discarded automobiles. is there.

And a pair of link levers that pivotably connect each other end of each of the pair of cutting blades and each of the pair of work arms. Since the blade blade pivot support shafts are pivotably connected to the vehicle body, the support shafts can be firmly fixed to the vehicle body.

  Therefore, the length of the scissors blade pivot support shaft that extends between the pair of cutting scissors blade that the scissors blade pivot support shaft supports and the vehicle main body to which the support shaft is fixed can be increased. More preferably, the length of the blade pivot support shaft can be made longer than the diameter of the blade pivot support shaft. For this reason, it is possible to make the pivot support shaft portion, which is loaded at the time of cutting, robust, and to reduce distortion and deterioration over a long period of time.

  This cutting rod is not only used in scrap dismantling work of discarded automobiles, but is also effectively used particularly for separating and dismantling construction waste materials and pipe waste materials. The waste materials to be mainly cut are, for example, long and irregular shaped waste materials such as reinforcing bars, window sashes, indoor water supply pipes and water distribution pipes in building demolition waste materials.

  When the pair of work arms are in the open state, the long waste material to be cut is gripped with a pen, and the hydraulic operation boom and the pen are moved by hydraulic operation to cut the length by which the pair of work arms are open. The scrap material is positioned between the pair of cutting blades in the open state. Next, by driving both working arms to the closed state, the pair of cutting blades are closed, whereby the long waste material between them is sheared.

  According to a preferred embodiment of the present invention, each of the pair of cutting scissors blades includes a single blade having a sharpening surface on the opposite side of the rubbing surface between the cutting scissors blades. This makes it difficult for chips to be produced during cutting and avoids the loss of recovered resources.
