Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete block breaking device for breaking a concrete block into several pieces to manufacture a decorative block having a breaking surface.

[0002]

[Technical field to which the device belongs]

 Conventional breaking machines for manufacturing concrete blocks having a breaking surface include one in which the lower blade rises and one in which the lower blade is fixed and the breaking table descends at the time of breaking by a spring. In the former case, since the block is lifted by the rising of the blade, the vertical pressure between the upper blade and the upper blade is out of order and is often damaged. In the latter, since the breaking table and the front and rear feeders are independent, a loss time occurs in the continuous breaking process.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to eliminate the risk of breakage in a conventional fixed lower blade type device and to increase the speed of continuous breakage to improve productivity.

[0004]

[Means for Solving the Problems]

 According to the present invention, a concrete block supply device and a breaking table are fixed to a table device that can be raised and lowered by adjusting the air pressure of an air spring, and the upper end of the fixed block is projected near the breaking table when the breaking table descends. A concrete block comprising a blade, an upper blade vertically pushed by a cylinder, a side blade horizontally pushed by the cylinder, and a device for discharging a fracture block from a fracture table. It is a breaking device. According to the present invention, since the concrete block supply device and the breaking table are provided in the same table device, it is possible to cut at a correct position even when performing high-speed work. The air spring increases / decreases the air in time by an electric switching valve that works in conjunction with the supply of concrete blocks to raise / lower the table device. The concrete block supply device is suitably a chain conveyor with a hook for feeding the concrete block.

【Example】

 Embodiments will be described below with reference to the drawings. FIG. 1 is a front view, and 1 is a breaking machine frame, on which an upper blade 4 fixed to an upper blade mounting member 3, a hydraulic cylinder 2 for vertically pressing the upper blade 4, and a cylinder from the front and back of the drawing are shown. The side blade 6 fixed to the No. 5 is fixed, and the lower blade 7 fixed to the lower part by a fixing jig 7'is fixed to the lower part, and a breaking table 18 is provided in the vicinity thereof. The breaking table 18 is provided with a slit so that the lower blade can be projected and retracted. Reference numeral 9 is a table device, both wings of which are connected to air springs 10 and 10 ′ fixed to an air spring fixing device 8. The air springs 10 and 10 'can increase or decrease the amount of air inside by an electric switching valve (not shown). Further, the table device 9 is provided with a chain conveyor 14 with a hook 17 for feeding the concrete block 16 to the breaking table 18, and an electric motor 13 for driving the chain conveyor 14 via a pulley. 15 is a product delivery conveyor. Further, 11 is a front and rear tuning arm receiver, 11 'is a rotary shaft, and 12 is a tuning arm.

When the concrete block 16 is sent out by the hook 17 attached to the chain conveyor 14 to a predetermined position on the breaking table 18 which is integrated with the table device 9, the upper blade 4 and the side blades 6 respectively break positions of the concrete block 16. Touch. Then, when the upper blade 4 is pushed by the action of the hydraulic cylinder 2, the bottom surface of the concrete block 16 is pushed by the breaking table 18. At the same time, the air pressure of the air springs 10 and 10 'is released, and the entire table device 9 descends as shown in FIG. 2 to absorb the pressure impact of the lower surface of the concrete block and the upper blade, and the lower blade 7 breaks the breaking table 18. The concrete block 16 is cut out while protruding from the slit and the pressing force of the upper blade 4 and the side blade 6. In this way, the concrete block 16 is stably held until the table device 9 is pressed by each blade, so that the cutting is performed accurately. After the breakage, the upper blade 4 rises and the side blade 6 retracts, and at the same time, the air springs 10 and 10 'are filled with air to raise the table device 9 and the lower blade 7 retracts from the breaking table 18. Next, the next concrete block 16 is fed to a predetermined position on the breaking table 18, and the cut concrete block is fed by the product feeding conveyor 15. The tilt of the table device 9 is adjusted by mounting the tuning arms 11 and 12 which are connected to the table device 9 and lift the table device 9 in an equilibrium direction.

[0007]

[Effect of device]

 According to the present invention, the concrete block breaking device of the lower blade fixed type with the least breakage is improved, and the feeding device and the breaking table are integrated as a table device to move up and down, so that the concrete block can be continuously and rapidly. The production efficiency is extremely high.
