By adjusting the nozzle pressure or the rotation trajectory of the gun 300 differently, the effect of improving the blasting operation more efficiently is realized.

The rotation trajectory of the nozzle terminal of the shot gun 300 can be configured to be rotated in various forms and trajectories, as well as up, down, left, and right by adding a separate rotation control device capable of rotating at a free angle. .

In more detail, the ground control unit 10 and the control unit 20 intensively set the trajectory of the nozzle terminal of the shot gun 300 as a "Z"-shaped rotation trajectory when paint or foreign substances are relatively thick and attached to the surface of the hull. Control the area so that the shot ball can be sprayed, and when paint or foreign substances are generally attached to the surface of the hull, it is controlled so that the shot ball can be sprayed evenly and widely by making an “8”-shaped rotation trajectory, and coating the surface of the hull. However, when the foreign material is relatively thick and strongly attached, it is characterized in that the "spiral" type rotation trajectory is used to control the shot ball to be sprayed by partially overlapping the movement trajectory.

In addition, the ground control unit 10 is a space in which the work manager controls the blasting operation on the ground, the control unit 20 is a space in which the worker riding in the bucket controls the blasting operation, and the ground control unit 10 and the control unit 20 are electrically connected in parallel to control the blasting operation from either side, and the ground control unit 10 and the control unit 20 simultaneously perform operation control to prevent accidents (10) and the control unit 20 is characterized in that when either one starts the operation, the other side is characterized in that the control circuit is blocked so that the control operation is not made and the red light blinks at the same time.

In addition, a control panel is formed on the ground control unit 10 and the control unit 20, and an operation control device is configured on the control panel to control the blasting operation, and the operation control device is a joystick or other operation control device. It is possible.

On the other hand, the blasting apparatus of the present invention is characterized in that it comprises a collecting and separating part 900 to which the lower and upper one side of the discharge pipe 112, the upper part of which is connected to the lower part of the discharge hole 110 of the main housing 100, is connected. do it with

The collection and separation unit 900 collects scattering dust, various foreign substances, and peeled paint and shot ball fragments generated during the blasting operation, and collects only the shot ball fragments after the blasting operation is completed so that they can be recycled.

Specifically, the collection/separation unit 900 includes a body 910 to which a lower portion and an upper one side of the discharge pipe 112 are connected, and a blowing fan 920 installed on one side of the inner side of the body 910, and, It is installed on one side of the inner side of the body 910 to form a first collecting space 932, and a plurality of perforated holes (not shown) are formed on the upper surface to collect the shot balls in the first collecting space 932. A second collection space 940 divided by the shot ball collecting part 930 and the short ball collecting part 930 and formed on the other side of the body 910, in which scattered dust, peeled paint and foreign substances are collected. characterized in that it is composed.

That is, the collection and separation unit 900 includes relatively light scattered dust, peeled paint and foreign substances (hereinafter, 'foreign substances') contained in the short ball fragments collected from the discharge pipe 112 by the blowing fan 920. ) is flown to the other side of the body 910 and collected in the second collection space 940, and the relatively heavy shot ball fragments are not blown to the other side by the blowing fan 920, but rather, the short ball collecting unit. By passing through the perforated hole formed in the upper surface of the 930 and being collected in the first collection space 932, the recycling of short balls or short ball fragments realizes an easier effect.

At this time, it will be apparent that the air volume and wind speed of the blowing fan 920 are set in a range in which the short ball or short ball fragments do not fly, and the size of the perforated hole of the short ball collecting unit 930 is larger than the size of the short ball. It will be obvious that it is formed large, and it is also possible to separate and collect the shot ball or shot ball fragments, scattering dust, peeled paint and foreign substances by using an electromagnet instead of the blowing fan 920 .

In addition, the body 910 has an openable and openable door (not shown) formed on one side and the other side so that the collected shortball fragments and foreign substances can be more easily collected, and the first without being separated by the blowing fan 920 . Foreign substances collected in the collecting space 932 or accumulated on the upper surface of the short ball collecting unit 930 may be removed by a worker directly cleaning from the inside.

As a result, the blasting device of the present invention is more stably and firmly close to the outer surface of the hull by using the protective pad 200 of a flexible material to prevent the shot ball fragments from being discharged to the outside of the body housing 100 as well. Rather, as the body housing 100 is installed to be rotated up and down, it is more firmly close to the outer surface of the curved or inclined hull, thereby more effectively preventing the short ball fragments from being discharged to the outside of the body housing 100. It is possible to obtain the effect of further improving the work efficiency.
