[0025] Step 1: The cylinder of the blocking structure drives the door panel to move upward along the guide rail structure, and the guide rail structure opens the front end of the box body.

[0026] Step 2: The first motor of the adjustable material guiding structure drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the horizontal axis to rotate, the horizontal axis drives the connecting plate to rotate, the connecting plate drives the material guiding plate to rotate, the front end of the material guiding plate rotates to the upper end of the discharge conveyor belt close to the box body, the rear end of the material guiding plate rotates to the lower front side of the rotating roller at the upper end of the front side, the cylinder of the blocking structure drives the door plate to move downward along the guide rail structure, the guide rail structure closes the front end of the box body, and the closed guide rail structure is slidably connected with the adjustable material guiding structure through the groove, and the blocking structure combines the groove and the material guiding plate to close the box body;

[0027] Step 3: The driving structure drives the rotating roller to rotate clockwise, and the rotating roller drives the hollow crawler to rotate clockwise along the annular plate. The hollow crawler drives the photovoltaic module frame connector to roll, and the sandblasting machine pulls the sand in the collection box for sandblasting.

The ground sand body falls directly into the circulating sandblasting structure through the rolling driving part of the crawler drive structure, and the sand body does not fall to the bottom of the crawler drive structure, so as to avoid the sand body falling to the bottom of the crawler drive structure and protect the crawler drive structure. After grinding, the sealing structure is opened, and the crawler drive structure rotates counterclockwise again. The crawler drive structure drives the ground photovoltaic component frame connector to fall onto the adjustable material guide structure, and falls onto the discharging conveyor belt through gravity for discharge, so as to realize automatic loading and unloading and protect the crawler drive structure at the same time.
