[0031] The working principle and usage process of this invention: When in use, the unloading device is placed at the target position, and then the conveyor belt 5 is moved by the drive roller 7. The unloading is then carried out by the conveyor belt 5. When it is necessary to adjust the orientation and tilt angle of the conveyor belt 5, the control position adjustment component 287 retracts. At this time, the pressure regulating piston 286 moves towards the first limit plate 288. The movement of the pressure regulating piston 286 synchronously extracts the transmission fluid 25 in the first liquid storage pipe 22 and the second liquid storage pipe 26. At this time, the first adjustable piston rod 285 and the second adjustable piston rod 289 move towards the liquid storage cylinder 24. At this time, the limiting support rod 27 and the annular support plate 20 are released from their limiting and fixing positions. At this time, the user can move the lifting base 6 up and down to tilt the conveyor belt 5 accordingly. At the same time, the user can rotate the annular support plate 20 relative to the support base 1 by moving the lifting base 6, thereby rotating the conveyor belt 5 relative to the support base 1. This allows the user to adjust the tilt angle of the conveyor belt 5 and rotate it at the same time according to the actual needs of the site. Through the dual customization of the orientation and posture of the conveyor belt 5, the unloading device can better meet the user's needs. After the posture adjustment of the conveyor belt 5 is completed, the control position adjustment component 287 extends. At this time, the pressure regulating piston 286 moves away from the first limit plate 288. Through the movement of the pressure regulating piston 286, the transmission fluid 25 is pressurized into the first liquid storage pipe 22 and the second liquid storage pipe 26. At this time, the first adjustable piston rod 285 and the second adjustable piston rod 289 both move away from the liquid storage cylinder 24. At this time, the deformable reinforcing plate 283 cooperates with the adjustable fixing plate 284 to lock and fix the limit support rod 27. The second adjustable piston rod 289 cooperates with the annular fixing plate 290 to lock and fix the annular support plate 20. When cleaning of the conveyor belt 5 is required, the limiting mounting frame 33 is vertically reciprocated by intermittently controlling the mutual repulsion between the first drive plate 32 and the second drive plate 37. At this time, the adjustable cleaning brush 34 also reciprocates vertically. The vertically reciprocating adjustable cleaning brush 34 beats the conveyor belt 5, which, combined with the lateral movement of the conveyor belt 5, achieves dual cleaning of the conveyor belt 5. At the same time, the adjustable scraper 35 contacts the conveyor belt 5 to scrape off residual debris, achieving further cleaning of the conveyor belt 5. After cleaning is completed, the first drive plate 32 is released. The intermittent mutual repulsion between the first drive plate 32 and the second drive plate 37 causes the limiting mounting frame 33 to fall back under the action of gravity, thereby causing the adjustable cleaning brush 34 and the adjustable scraper 35 to disengage from the conveyor belt 5. At this time, the driving force of the first drive plate 32 and the second drive plate 37 can be controlled to make the limiting mounting frame 33 move vertically in a small amplitude, thereby causing the guide side plate 36 to collide with the limiting brake plate 31 intermittently. The collision causes the adjustable cleaning brush 34 to vibrate, and the vibration causes the debris stuck on the adjustable cleaning brush 34 to fall off, thereby realizing the self-cleaning of the adjustable cleaning brush 34. Thus, through the cooperation of multiple structures, users can quickly and accurately adjust the orientation and tilt angle of the conveyor belt 5 according to the actual needs of the site, improving the applicability of the unloading device and enabling the unloading device to better meet the diverse unloading needs of users. Secondly, the invention has a cleaning function, allowing users to quickly and thoroughly clean the conveyor belt 5 according to actual needs, and the cleaning structure can achieve self-cleaning, making the functions of the unloading device more abundant. In addition, the invention has a simple structure and is easy to use, making it worthy of promotion and use.
