[0015] (1) The second rectangular ring is driven to move in the vertical direction by the blanking angle adjustment component to change the height of the second rectangular ring. The second slider located in the second rectangular ring drives the height of the movable seat to change. The movable seat slides relative to the blanking plate to change the inclination angle of the blanking plate. After the inclination angle of the blanking plate is adjusted, the staff drives the lifting sleeve to rotate. The lifting sleeve drives the prism and the first screw rod to rotate, changing the length of the first screw rod in the first threaded sleeve, so that the first slider and the first threaded sleeve move vertically relative to the first rectangular ring. Through the design of the synchronous screwing mechanism, when the lifting sleeve rotates, the lifting sleeve drives the second screw rod to rotate synchronously, changing the length of the second screw rod in the second threaded sleeve, so that the second slider and The second threaded sleeve moves vertically relative to the second rectangular ring. When the lifting sleeve rotates, the first slider and the corresponding second slider move synchronously in the vertical direction to change the height of the blanking plate, thereby adjusting the distance between the two adjacent blanking plates. The distance between the two adjacent blanking plates and the inclination angle of each blanking plate can be adjusted according to actual conditions so that the blanking plates are in appropriate positions. The staff drives the blanking device to move so that the uppermost blanking plate is located below the material discharge port, and the lowermost blanking plate is located above the conveyor belt. The material is buffered by multiple blanking plates, reducing the force of the material hitting the conveyor belt, thereby reducing the wear on the conveyor belt, improving the service life, and facilitating practical use.

[0016] (2) The staff drives the top plate upward to disengage the limiting column from the corresponding limiting hole, and the tension spring is in a stretched state, releasing the limitation on the position of the connecting shaft and the lifting sleeve. The staff drives the lifting sleeve to rotate, so that the connecting shaft drives the first sprocket to rotate, and the first sprocket drives the second sprocket to rotate through the first chain, and the second sprocket drives the corresponding second screw to rotate synchronously. When there is no need to rotate the lifting sleeve, the top plate is released, and the tension spring drives the top plate downward to insert the bottom end of the limiting column into the corresponding limiting hole, limiting the position of the connecting shaft and the lifting sleeve to prevent the lifting sleeve and the connecting shaft from rotating due to non-human factors. When the second rectangular ring moves vertically relative to the first rectangular ring, the second rectangular ring drives the fixed sleeve to move vertically, so that the connecting shaft drives the lifting sleeve to slide relative to the prism. After the second rectangular ring moves vertically relative to the first rectangular ring, it will not interfere with the synchronous transmission between the lifting sleeve and the second screw.

[0017] (3) The blanking plate and the first slider are rotatably connected by the design of the first rotating shaft and the bearing, the movable seat and the second slider are rotatably connected by the design of the second rotating shaft and the bearing, the movable seat and the blanking plate are slidably connected by the design of the guide groove and the guide block, the first screw rod and the first rectangular ring are rotatably connected by the design of the first fixed plate and the bearing, and the second screw rod and the second rectangular ring are rotatably connected by the design of the second fixed plate and the bearing;

[0018] (4) The staff drives the bolt to rotate so that the bolt disengages from the corresponding threaded hole, thereby releasing the fixed relationship between the third fixing plate and the control box body. The staff manually drives one of the third threaded sleeves to rotate, and the third threaded sleeve drives the corresponding third sprocket to rotate. The third sprocket drives the other third sprocket and the third threaded sleeve to rotate through the second chain, so that the two third threaded sleeves rotate synchronously. The length of the third screw rod in the third threaded sleeve can be changed to move the third screw rod in the vertical direction. The third screw rod drives the second rectangular ring to move in the vertical direction through the support plate. When there is no need to adjust the height of the second rectangular ring, the staff drives the bolt to rotate, and the bottom end of the bolt is screwed into the corresponding threaded hole. The third fixing plate is fixed relative to the control box body, so that the third threaded sleeve is fixed relative to the control box body, thereby preventing the third threaded sleeve from rotating relative to the control box body due to non-human factors.

The staff drives the lifting sleeve 11 to rotate so that the connecting shaft 18 drives the first sprocket 19 to rotate. The first sprocket 19 drives the second sprocket 20 to rotate through the first chain 21, and the second sprocket 20 drives the corresponding second screw rod 16 to rotate synchronously. When there is no need to rotate the lifting sleeve 11, the top plate 24 is loosened, and the tension spring 25 drives the top plate 24 to move downward so that the bottom end of the limiting post 23 is inserted into the corresponding limiting hole 26, limiting the position of the connecting shaft 18 and the lifting sleeve 11 to avoid lifting. When the lowering sleeve 11 and the connecting shaft 18 rotate due to non-human factors and the second rectangular ring 7 moves vertically relative to the first rectangular ring 5, the second rectangular ring 7 drives the fixed sleeve 14 to move vertically, so that the connecting shaft 18 drives the lifting sleeve 11 to slide relative to the prism 10.

The design of the first fixed plate 31 and the bearing,The first screw rod 12 and the first rectangular ring 5 are rotatably connected, and the second screw rod 16 and the second rectangular ring 7 are rotatably connected through the design of the second fixing plate 32 and the bearing. The staff drives the bolt 39 to rotate so that the bolt 39 is disengaged from the corresponding threaded hole 40, thereby releasing the fixed relationship between the third fixing plate 38 and the control box body 1.

The third screw rod 34 drives the second rectangular ring 7 to move vertically through the support plate 33. When the height of the second rectangular ring 7 does not need to be adjusted, the staff drives the bolt 39 to rotate. The bottom end of the bolt 39 is screwed into the corresponding threaded hole 40. The third fixing plate 38 is fixed relative to the control box body 1 to fix the third threaded sleeve 35 relative to the control box body 1, preventing the third threaded sleeve 35 from rotating relative to the control box body 1 due to non-human factors.
