The present invention is a plastic working device that removes rust, oil, and other foreign substances from the surface of steel plate before painting work on steel plate such as ship's outer plate. The present invention relates to an automatic blasting apparatus on an outer surface of a steel plate, which is capable of blasting by spraying a blasting material, which is a blasting material, in a closed space, and recovering waste, while moving back and forth by a rear motor.

Hereinafter, the subject matter of the present invention will be described with reference to the accompanying drawings.

The spray material is sprayed through the spray nozzle 4 to the spray chamber 3 through the hose 2 connected to the air delivery motor 1, and the spray nozzle 4 is fixed shaft 5 and the spray chamber 3. It is connected to the moving shaft 8 as a motor 6 and a crank 7 provided outside, and is connected as a bellows 9 between the injection chamber 3 and the delivery hose 2.

Sealed rubber (10) (10 ') and " The spraying material that has been sprayed to prevent the leakage of the spraying material by attaching two types of sealed rubbers (11, 11 ') in the shape of the hose 13 by the suction motor 12 through the discharge hole " A " Accumulated in the diesel storage tank (14), some are dropped into the tank (15) and re-injected, some are sprayed by the filter (16) (16 ') and dust is discharged through the outlet (17).

Injector chamber 3 connects the tracks B and B 'formed of magnets 22 and 22' as connecting rods 18 and 18 ', and the tracks B and B' are motors 19 (19 ') and gears 20, 20' and brackets 21 and 21 'coupled to each other so as to be engaged with the gears 20 and 20' by the chains 23 and 23 '. The terminals 24 and 24 'attached to the inside of the magnets 22 and 22' are slid into the power supply rails 25 and 25 'to pass through the power supply rails 25 and 25'. The magnetizing force is generated only in the magnets 22 and 22 '.

In the description of the operation of the present invention configured as described above, first, the injection material supply and recovery apparatus will be described with reference to FIG. COPPERSLAG, an injection material that is pressurized by the air delivery motor 1 through the delivery hose 2 at a high pressure, is injected onto the surface of the iron plate through the injection nozzle 4 in the injection chamber 3. The work of polishing and removing the foreign substance by frictional resistance is achieved, and in order to perform effective spraying work with a wider range, the fixed shaft 5 is installed at the lower end of the spray nozzle 4 and the upper part of the upper part of the spray chamber 3 is The crank (7) connected to the motor (6) vibrates the moving shaft (8) located at the upper end of the injection nozzle (4) to the left and right by spraying the nozzle (starting from the fixed shaft (5) of the injection nozzle (4) The end of 4) is rotated to the left and right, and the blasting work is performed in a large area by dispersing the injection material in the injection chamber 3 by the distance of "C".

At this time, the injection nozzle 4 connected to the delivery hose 2 is vibrated left and right by the crank 7 in the injection chamber 3, so that the bellows 9 is stretched between the injection chamber 3 and the delivery hose 2. The air pressure in the injection chamber 3 is prevented from leaking and the simultaneous injection nozzle 4 smoothly vibrates from side to side.

In addition, the lower end of the spray chamber 3 is also equipped with a sealant rubber (10) (10 ') so that the spray material does not leak to the outside during the blasting operation and the " "A double elastic seal (11) (11 ') which is excellent in shape is attached, and the rubber (11) (11') receives a slight elasticity and adheres to the surface so that the spray material does not leak, thereby making the work efficient It is to increase the effectiveness of prevention.

Since the spraying material that has been sprayed in the spraying type (3) is recovered through the hose 13 from the spray chamber 3 by the suction force of the suction motor 12, and the kernel which does not crumble in the process of being recovered is stored in the storage tank ( If it falls to 14) and accumulates a certain amount, it is transferred to the lower tank 15 by self-centering and mixed with the strong air pressure of the air delivery motor 1 again and re-injected through the delivery hose 2, and the small and light grain Is first filtered by filter 16 (16 ') and then discharged through outlet 17.

Next, the attachment apparatus of the blasting apparatus, which is fixed to the iron plate surface by a magnet connected in an orbital manner, which is the subject of the present invention, is moved back, front, left, and right by a motor, as shown in FIGS. 2, 3, 4, 5, and 5. Referring to the figure 6 is as follows.

A plurality of rectangular magnets 22 and 22 'are connected at regular intervals to form an endless track B and B', and the chains 23 and 23 'coupled to the inside of the magnets 22 and 22'. Manufactured by the same length as the contact part (S) for the part that rotates and engages with the driving motor (6) (6 ') and the gear (20) (20') by contacting the steel plate surface of the lower part of the injection chamber (3) &Quot; + " terminal pins 26 "-" formed of long contact grooves on the side of the power contact rails 25 and 25 'to form the power contact rails 25 and 25'. &Quot; Attach the contact terminals 24 and 24 " passing through while contacting the inside of the terminal plate 26 'to the power contact rails 25 and 25' at the same time as the drive motors 19 and 19 'rotate. When current flows, the jars 24 and 24 'of the rotating magnets 22 and 22' are connected to the "+" terminal plate 26 and the "_" terminal plate 26 'of the power contact rails 25 and 25'. Magnet 22 only sliding to the bottom contact vial (S) that slides into the plate and is energized at the same time A magnetic force of (22 ') is generated and the terminals (24) and (24') of the magnets (22) and (22 ') raised to the top through the power contact rails (25) and (25') are turned off and have a self-adhesive force. To lose.

In addition, by using the speed converter of the two driving motors, the two can be rotated at the same speed at the same time or differently or reversely rotated to move forward, backward, left and right, and also on the surface in the vertical state or the surface in the reverse vertical direction. This can be done without this.

Therefore, by using the device of the present invention can be conveniently used for blasting work such as large steel structures such as ships to provide a blasting working apparatus having a high workability.
