[0028] Working principle: The utility model is a height-adjustable material box conveying device. During use, when the height of the conveyor belt 21 needs to be adjusted, the two rocking wheels 9 are rotated, the rocking wheels 9 drive the rotating rod 6 to rotate in the inner cavity of the second bearing 8, the rotating rod 6 drives the worm 5 to rotate, the worm 5 drives the worm wheel 4 to rotate, the worm wheel 4 drives the threaded tube 23 to rotate in the inner cavity of the first bearing 3 and the outer edge of the threaded rod 11, the threaded rod 11 moves relative to the threaded tube 23 under the action of the thread, the threaded rod 11 drives the top plate 10 to move, and the top plate 10 drives the conveyor belt 21 to move, so as to adjust the height of the conveyor belt 21;

[0029] When the inclination angle of the conveyor belt 21 needs to be adjusted, the right-side wheel 9 is rotated to make the two threaded rods 11 on the right side move relative to the threaded tube 23. When the two threaded rods 11 on the right side move upward relative to the threaded tube 23, the height of the right side of the conveyor belt 21 rises and tilts. When the two threaded rods 11 on the right side move downward relative to the threaded tube 23, the height of the right side of the conveyor belt 21 drops and tilts. During this process, the slider 15 moves in the inner cavity of the slide groove 16, and at the same time, the top plate 10 rotates around the adjacent pin shaft 14, and the slider 15 rotates around the adjacent pin shaft 14, so as to complete the adjustment of the inclination angle of the conveyor belt 21.

[0030] The material box is lifted and transported by adjusting the height of the conveyor belt 21. After the conveyor belt 21 is transported to an appropriate height, the motor 22 is started to drive the conveyor belt 21 to rotate and transport the material box laterally. This device can not only play the role of lifting and transporting, but also can transport the material box laterally, making transportation more convenient. At the same time, the inclination angle of the conveyor belt 21 can be adjusted as needed, so that the device can be suitable for slope transportation, which greatly improves the scope of application of the device.
