[0016] 2. After adjusting the height of the support frame, the inclination of the conveyor belt needs to be adjusted. At this time, drive motor one, which drives lead screw one to rotate. Lead screw one drives the sliding block to slide in the support block. The sliding of the sliding block ultimately drives connecting rod two, i.e., the U-shaped rod, to slide on the support plate, adjusting the angle between the conveyor belt and the support plate. Since there are two adjustment mechanisms, the angle between the conveyor belt and the support plate is finally adjusted to a suitable position, ensuring that the feed end on the higher side and the discharge end on the lower side of the conveyor belt reach the appropriate height, which facilitates the conveying of rice. It is simple to adjust, easy to operate, has an expanded range of applications, and enhances practicality.
[0017] 3. By setting inclined baffles, extension plates, and leak-proof plates on both sides of the conveyor frame, the rice is ensured to be transported in the middle of the conveyor belt. The setting of sponges prevents rice from leaking from both ends of the conveyor belt due to its small size, thus avoiding waste and affecting the conveying efficiency.
[0018] 4. The omnidirectional wheels allow for easy movement as needed, making it compatible with equipment of different heights and expanding its applicability. Attached Figure Description

[0025] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] An example is a height-adjustable rice conveying device, such as... Figure 1-4 As shown, the system includes a support frame 1, which also includes a lifting mechanism for driving the support plate 6 to rise and fall. The lifting mechanism includes four drive rods 12 connected to connecting rods 11. Each connecting rod 11 is vertically fixed to four points on the bottom surface of the support plate 6. Each connecting rod 11 is slidably connected to a hollow support column 13. The other ends of the four drive rods 12 are hinged to the two ends of two parallel rotating rods 14. Gears 15 are fixed in the middle of each rotating rod 14. A rack 16 is provided in the middle of each of the two gears 15. One end of the rack 16 is connected to the piston rod of cylinder 22. The rack 16 has teeth on both sides that mesh with the two gears 15. A U-shaped limiting sleeve 17 is provided at one end of each drive rod 12. The limiting sleeve 17 is hollow in the middle. A cylindrical rod 18 is rotatably connected to the bottom side of the connecting rod 11. The cylindrical rod 18 is locked in the limiting sleeve 17. When the device is used to transport rice, the entire device is first moved to the rice storage area. Then, the height of the conveyor belt 3 is adjusted according to the height of the rice discharge port. First, the cylinder 22 is started. The cylinder 22 drives the rack 16 to slide. The gear 15 meshing with the rack 16 rotates, which drives the rotating rod 14 to rotate. The rotating rod 14 rotates, which drives the drive rod 12 to rotate, which drives the connecting rod 11 to slide up and down in the support column 13. Finally, it drives the entire support plate 6 to rise and fall. The whole process is simple and easy to operate. The limiting sleeve 17 at the end of the drive rod 12 and the cylindrical rod 18 at the bottom of the connecting rod 11 ensure that the connecting rod 11 slides smoothly in the cylindrical tube.
[0027] Furthermore, a conveyor frame 2 is provided in the support frame 1, and a conveyor belt 3 is provided in the conveyor frame 2. The conveyor frame 2 is characterized by having mirror-shaped adjustment mechanisms on both sides. Each adjustment mechanism includes a U-shaped rod 4 hinged to the bottom surface of the conveyor frame 2. A connecting rod 5 is hinged to the middle of the two side rods of the U-shaped rod 4, and the other end of the connecting rod 5 is hinged to the support plate 6. A connecting rod 7 is hinged between the ends of the two side rods of the U-shaped rod 4. A sliding block 8 is provided in the middle of the connecting rod 7. A lead screw 9 passes through the sliding block 8. The lead screw 9 is located in an L-shaped support block 24. A guide groove is provided in the crossbar of the support block 24. The sliding block 8 is slidably connected to the guide groove of the support block 24. A motor 27 is coaxially fixed to the end of the lead screw 9. Two adjustment mechanisms... The motors 1 and 27 in the structure are close together. After adjusting the height of the support frame 1, the inclination of the conveyor belt 3 needs to be adjusted. At this time, the drive motor 27 drives the lead screw 9 to rotate. The lead screw 9 drives the sliding block 8 to slide in the support block 24. The sliding of the sliding block 8 ultimately drives the connecting rod 27, i.e., the U-shaped rod 4, to slide on the support plate 6, adjusting the angle between the conveyor belt 3 and the support plate 6. Since there are two adjustment mechanisms, the angle between the conveyor belt 3 and the support plate 6 is finally adjusted to a suitable position, ensuring that the feed end of the high side and the discharge end of the low side of the conveyor belt 3 reach a suitable height, which is convenient for conveying rice. It is simple to adjust, easy to operate, has an expanded range of applications, and enhances practicality.
[0028] Furthermore, inclined baffles 19 are symmetrically arranged on both sides of the conveyor frame 2. The baffles 19 on both sides gradually move closer to the conveyor belt 3. An extension plate 20 is vertically fixed to the bottom edge of the baffle 19. A leak-proof plate 21 is slidably connected to the opposite sides of the two extension plates 20. A sponge is provided at the bottom of the leak-proof plate 21. A spring 23 is connected to the upper end of the leak-proof plate 21. The other end of the spring 23 is connected to the bottom surface of the baffle 19. The spring 23 drives the leak-proof plate 21 to fit against the conveyor belt 3. A discharge plate 25 is provided on both opposite sides of the conveyor frame 2. The bottom edge of the discharge plate 25 is hinged in the conveyor frame 2. The side of the discharge plate 25 is connected to the piston rod of the second cylinder 26. The other end of the second cylinder 26 is hinged in the conveyor frame 2. By setting inclined baffles 19, extension plates 20 and leak-proof plates 21 on both sides of the conveyor frame 2, the rice is ensured to be transported in the middle of the conveyor belt 3. The sponge prevents the rice from leaking from both ends of the conveyor belt 3 due to its small size, thus avoiding waste and affecting the conveying efficiency.
[0029] Furthermore, the inner side of the discharge plate 25 near the conveyor belt 3 is in contact with the ends of the extension plate 20 and the leak-proof plate 21.
[0030] Furthermore, each of the four support columns 13 is equipped with a self-locking caster wheel 10 on its bottom surface.
[0031] Working principle of a height-adjustable rice conveying device:
[0032] When the device is needed to transport rice, the entire device is first moved to the rice storage site. Then, the height of the conveyor belt 3 is adjusted according to the height of the rice discharge port. First, cylinder 22 is started. Cylinder 22 drives rack 16 to slide. Gear 15 meshing with both sides of rack 16 rotates, driving rotating rod 14 to rotate. Rotating rod 14 drives drive rod 12 to rotate, driving connecting rod 11 to slide up and down in support column 13. Finally, the entire support plate 6 is lifted up and down. The whole process is simple and easy to operate. The limiting sleeve 17 at the end of drive rod 12 and the cylindrical rod 18 at the bottom of connecting rod 11 ensure that connecting rod 11 slides smoothly in the cylindrical tube.
[0033] After adjusting the height of the support frame 1, the inclination of the conveyor belt 3 needs to be adjusted. At this time, the drive motor 27 drives the lead screw 9 to rotate. The lead screw 9 drives the sliding block 8 to slide in the support block 24. The sliding of the sliding block 8 ultimately drives the connecting rod 7, i.e., the U-shaped rod 4, to slide on the support plate 6, adjusting the angle between the conveyor belt 3 and the support plate 6. Since there are two adjustment mechanisms, the angle between the conveyor belt 3 and the support plate 6 is finally adjusted to a suitable position, ensuring that the feed end on the high side and the discharge end on the low side of the conveyor belt 3 reach a suitable height, which is convenient for conveying rice. It is simple to adjust, easy to operate, has an expanded range of applications, and enhanced practicality.
