[0026] The discharge mechanism 2 includes a discharge assembly and a pushing assembly. The discharge assembly is used for discharging materials downward; the pushing assembly is used for pushing the discharge assembly to move. The discharge assembly includes an extrusion cylinder 21 arranged inside the rotating table 17. A blanking frame 23 is arranged inside the extrusion cylinder 21. A blanking plate 24 is arranged inside the blanking frame 23. A blanking groove 213 is arranged inside the blanking frame 23. One end of the blanking plate 24 rotates around the blanking frame 23.

[0028] By arranging the extrusion block 22 to abut against the pressure vessel, the extrusion block 22 drives the extrusion cylinder 21 to move. After the extrusion cylinder 21 moves, it extrudes the first rotating rod 212. The first rotating rod 212 pulls the first connecting pin 28, the first connecting pin 28 drives the first pull rod 27 to move, the first pull rod 27 drives the pulling ball 26 to move, the pulling ball 26 pulls the sliding of the pulling groove 25, and the pulling groove 25 drives the blanking plate 24 to turn over; thus, the metal powder is discharged downward from the inside of the blanking groove 213.

[0029] The locking mechanism 5 includes a first inner groove 52 and a second inner groove 53 arranged inside the extrusion cylinder 21, and the first inner groove 52 and the second inner groove 53 are perpendicular to each other; a push rod 51 is arranged inside the first inner groove 52, the push rod 51 slides inside the first inner groove 52, and a second connecting pin 54 is arranged at the end of the push rod 51; an inner cavity 58 is formed on the blanking frame 23, a third elastic member 57 is arranged inside the inner cavity 58, a locking rod 56 is arranged inside the second inner groove 53, a third elastic member 57 is sleeved on the locking rod 56, the third elastic member 57 is arranged inside the inner cavity 58, the third elastic member 57 is used to push the locking rod 56 to reset, a locking hole 59 is formed on the blanking plate 24, and the locking rod 56 is engaged with the locking hole 59; a connecting groove 55 is formed on the locking rod 56, and the second connecting pin 54 slides inside the connecting groove 55.

[0030] By arranging the movement of the extrusion cylinder 21, the extrusion cylinder 21 drives the push rod 51 to move, the push rod 51 drives the second connecting pin 54 to move, the second connecting pin 54 slides inside the connecting groove 55, the connecting groove 55 drives the locking rod 56 to move horizontally, and the locking rod 56 moves out of the inside of the locking groove; when the locking rod 56 moves out of the inside of the locking groove, the extrusion rod 214 just pushes the first rotating rod 212 to rotate, so that the blanking plate 24 turns over, and the metal powder inside the blanking groove 213 starts to be discharged downward; when it is necessary to discharge the metal powder, the extrusion cylinder 21 is extruded on the pressure vessel; when the extrusion cylinder 21 leaves the pressure vessel, the blanking plate 24 resets, and the locking rod 56 enters the inside of the locking groove, thereby locking the blanking plate 24, so that the blanking plate 24 plugs the metal powder when not blanking.

[0031] Two support plates 12 are arranged on the machine shell 1, an adjusting rod 11 is arranged on the support plates 12, the adjusting rod 11 is used to drive the support plates 12 to move, a guide rod 13 is arranged on the support plates 12, a blower 16 is arranged inside the rotating table 17, and the blower 16 is connected to the blanking pipe 38.

[0032] By arranging the adjusting rod 11, the support plates 12 can be driven to move. Preferably, the adjusting rod 11 is a lead screw; the blower 16 sends the metal powder to the inside of the discharge pipe 14 through the blanking pipe 38.

[0033] When the present invention is in use and performing linear welding, for example, when welding the side wall of a pressure vessel, only the adjusting rod 11 needs to be driven. The adjusting rod 11 drives the support plate 12 to move, and the support plate 12 drives the machine housing 1 to move. At this time, the laser welding head 15 melts the metal powder discharged from the discharging mechanism 2, and the laser welding head 15 completes the welding of the pressure vessel. When arc welding is required, the welding head needs to be rotated so that the rotated blanking pipe 38, laser welding head 15, suction pipe, and camera 33 can perform the operations of blanking, welding, adsorption, and imaging. When adjusting, the motor 18 inside the machine housing 1 is started to rotate. The motor 18 rotates to drive the first gear 19 to rotate, and the first gear 19 drives the second gear 110 to rotate. The second gear 110 drives the rotating table 17 to rotate. The rotation of the rotating table 17 drives the guide groove 112 to rotate synchronously. The second abutting rod 47 moves downward, and the second abutting rod 47 pushes the third pull rod 42 to move. The third pull rod 42 flips, and the third pull rod 42 pushes the limit pin 44 to move. The limit pin 44 drives the slide plate 41 to move, and the slide plate 41 moves to drive the slider 410 to slide on the adsorption chamber 36. Thus, the two slide plates 41 extend to limit the metal powder discharged from the discharging mechanism between the two slide plates 41. When the metal powder passes through the suction port 37, the suction port 37 sucks the metal powder into the inside of the discharging assembly. The metal powder is cleaned, facilitating the camera 33 to image the weld seam. When the extrusion block 22 abuts against the pressure vessel, the extrusion block 22 drives the extrusion cylinder 21 to move.

The first pull rod 27 drives the pulling ball 26 to move, and the pulling ball 26 pulls the pulling groove 25 to slide. The pulling groove 25 drives the blanking plate 24 to flip. Furthermore, the metal powder is discharged downward from the inside of the blanking groove 213. When the extrusion cylinder 21 drives the push rod 51 to move, the push rod 51 moves to drive the second connecting pin 54 to move. The second connecting pin 54 slides inside the connecting groove 55, and the connecting groove 55 drives the locking rod 56 to move horizontally. The locking rod 56 moves out of the inside of the locking groove. When the locking rod 56 moves out of the inside of the locking groove, the extrusion rod 214 just pushes the first rotating rod 212 to rotate, so that the blanking plate 24 flips, and the metal powder inside the blanking groove 213 starts to be discharged downward. When it is necessary to discharge the metal powder, the extrusion cylinder 21 is extruded against the pressure vessel. When the extrusion cylinder 21 leaves the pressure vessel, the blanking plate 24 resets, and the locking rod 56 enters the inside of the locking groove, thereby locking the blanking plate 24 and making the blanking plate 24 block the metal powder when not discharging.
