[0034] Working principle of the present invention: When the mulberry leaf delivery device is in use, the personnel can conveniently rotate the adjustment stud 22 through the hexagonal adjustment block 25, so that it can rotate in the adjustment screw hole opened in the stabilizing plate 21, and the adjustment stud 22 is connected to the stabilizing seat 24, which can ensure the overall stability of the working frame 1, turn on the drive motor 16 and the stepper motor 41, the drive motor 16 drives the conveying roller 15 to rotate, and the stepper motor 41 drives the rotating roller 42 to rotate, so that the conveyor belt 14 can move on the adjusting roller 7, the pulling roller 37, the tensioning roller 36, the direction adjustment roller 43, the rotating roller 42 and the conveying roller 15, and the mulberry leaf delivery device can be used for conveying leaves. The leaves fall on the conveyor belt 14 on one side of the fixed frame 13 and can be conveyed to the conveyor belt 14 on the side of the adjusting frame 6. At this time, the electric telescopic rod 40 works to drive the telescopic slider 39 to slide in the telescopic slide hole 38 opened in the working frame 1, and then drives the movable frame 4. The movable frame 4 drives the adjusting frame 6 to move, and the positioning slider 3 connected to the movable frame 4 slides in the positioning slide groove opened by the positioning rod 2. At the same time, the adjusting frame 6 is connected to the positioning chain 9 through the fixed block 8 to ensure the overall stable operation of the movable frame 4 and the adjusting frame 6. When the movable frame 4 drives the adjusting frame 6 to move, the total length of the conveyor belt 14 remains unchanged. In this case, the pulling roller 37 on the movable frame 4 acts on the conveyor belt 14 to ensure stable delivery of the conveyor, and the adjustment roller 7 on the adjustment frame 6 can move to change the landing point of the mulberry leaves, thereby ensuring uniform delivery of the mulberry leaves. When the mulberry leaves are delivered, the scraper 28 connected to the bottom plate 29 acts on the conveyor belt 14 at the bottom, and the scraper 28 scrapes off the mulberry leaves adhering to the surface of the conveyor belt 14 to avoid waste of resources. At the same time, the connecting stud 26 connected to the scraper frame 11 is connected to the movable hole opened in the connecting plate 10 and is fixed by the fixing cap 12. The angle of the scraper frame 11 can be adjusted to improve the scraping effect. At the same time, the bottom The plate 29 is connected to the guide slide block and the guide slide groove 27 provided in the scraper frame 11 for sliding connection. When a person rotates the turntable 31, the pressing stud 30 can rotate in the pressing screw hole provided in the scraper frame 11. The pressing stud 30 rotates in the fixed bearing, which can drive the bottom plate 29 to move, thereby changing the force of the scraper 28 on the conveyor belt 14 to ensure the scraping effect. If the conveyor belt 14 of the delivery device is loose, the person can rotate the crank 35 to drive the tensioning screw 34, and the tensioning screw 34 rotates in the fixed bearing connected to the tensioning slide block 33, thereby driving the tensioning slide block 33 to slide in the tensioning slide hole 32 provided in the tensioning frame 17, which can drive the tensioning roller 36 to move, thereby adjusting the tightness of the conveyor belt 14 to ensure the delivery efficiency of the delivery device.
