[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0022] like Figure 1As shown, the conveyor belt self-balancing structure includes a mounting plate 1, a worm gear screw jack 2 is fixedly connected to the mounting plate 1, a lifting bracket 3 is connected to the worm gear screw jack 2, and the lifting bracket 3 is located above the mounting plate 1; both ends of the lifting bracket 3 are provided with bearing seats 6, and a main shaft 4 is provided above the worm gear screw jack 2. The main shaft 4 includes a mounting shaft 5, which is rotatably connected to the bearing seats 6.

[0023] In the above structure, the mounting plate 1 is fixed to the frame 12. The upper two ends of the lifting bracket 3 are provided with holes to connect with the main shaft 4 and the bearing seat 6. The lower middle part is provided with a hole for connecting with the worm gear screw jack 2. The belt surface of the conveyor belt passes around the main shaft 4. The bearing seat 6 is used to meet the following rotation process of the belt surface. The worm gear screw jack 2 is used to provide power for the lifting process of the main shaft 4, thereby realizing the adjustment of the belt surface angle and thus adjusting the belt surface to a horizontal and stable position.

[0024] like Figure 1 As shown, the worm gear screw jack 2 includes a lifting block 7, which is hinged to the middle of the lifting bracket 3; both ends of the mounting plate 1 are fixedly connected to brackets 8, and the top of the brackets 8 is fixedly connected to a limit frame 10, which has a parallelogram structure, and the mounting shaft 5 passes through the limit frame 10. The lifting block 7 internally engages with the screw of the worm gear screw jack 2. The lifting block 7 externally is spherical, and the lifting bracket 3 is provided with spherical holes that engage with the lifting block 7, thus forming a ball joint structure to achieve the hinge between the two. That is, the lifting block 7 and the lifting bracket 3 are hinged through the ball joint. During the synchronous lifting and lowering process of the lifting block 7 driving the lifting bracket 3, the mounting shaft 5 is restricted by the limiting frame 10, and the lifting bracket 3 will rotate relative to the ball joint at a certain angle, thereby realizing the angle change process of the belt surface. The conveyor belt surface self-balancing structure is provided with two sets on the whole conveyor belt. The lifting bracket 3 of the two sets of mechanisms moves in opposite directions, which can avoid the belt surface from being damaged due to excessive stretching deformation caused by the above-mentioned angle change process. At the same time, the use of the two sets of mechanisms can expand the adjustment range of the tilt angle of the belt surface relative to the frame 12, which is more conducive to the use environment of uneven ground, adjusting the belt surface to a horizontal position and improving the balance effect.

[0025] like Figure 1 As shown, the limiting frame 10 is a vertical parallelogram structure and is symmetrically arranged at both ends of the frame 12. The limiting frame 10 has a limiting and anti-detachment effect on the main shaft 4, which is conducive to further improving the stability of the belt surface. Driven by the worm gear screw jack 2, the belt surface can be adjusted within a maximum angle range of ±30° according to the size selection of the limiting frame 10, thereby achieving the horizontality of the entire belt surface.

[0026] like Figures 1 to 3As shown, the main shaft 4 is located between the brackets 8 at both ends of the mounting plate 1. In the above structure, the brackets 8 located on both sides of the main shaft 4 restrict the relative movement between the belt surface and the main shaft 4 in the direction perpendicular to the belt surface running, so that the belt surface always cooperates with the main shaft 4, further reducing the instability of the belt surface.

[0027] like Figures 1 to 3 As shown, an extension rod 9 is fixedly connected to one side of the bracket 8. The extension rod 9 is used to connect to the frame 12 and provide overall support for the self-balancing structure of the conveyor belt surface.

[0028] like Figure 1 As shown, the lifting bracket 3 has a U-shaped structure. The U-shaped lifting bracket 3 enables the installation of the mounting shafts 5 at both ends of the main shaft 4, which helps to ensure that the main shaft 4 is level overall, thereby ensuring the balance of the conveyor belt surface.

[0029] like Figure 1 As shown, a motor 11 is located on one side of the worm gear screw jack 2, and both the worm gear screw jack 2 and the motor 11 are located at the bottom of the mounting plate 1. The input end of the worm gear screw jack 2 is connected to the motor 11 via a universal joint to achieve power transmission. Mounting the main body of the worm gear screw jack 2 and the motor 11 at the bottom of the mounting plate 1 does not occupy the space above the mounting plate 1, facilitates the connection of the wiring harness, and helps to avoid the complexity of the overall structure caused by the excessive concentration of components.

[0030] like Figure 1 As shown, the worm gear screw jack 2 is bolted to the mounting plate 1, and the bearing seats 6 are bolted to both ends of the lifting bracket 3. This structure, installed using multiple bolts, is simple and convenient to operate, and offers high installation stability.

[0031] The belt surface adjustment process is as follows: Motor 11 provides power to worm gear screw jack 2, which transmits the lifting power to lifting bracket 3. Lifting bracket 3 synchronously lifts the main shaft 4 installed on it. Because the lifting block 7 and lifting bracket 3 are connected by ball joint hinge and the movement of the mounting shaft 5 is restricted by the limit frame 10, the mounting shaft 5 moves within the limit frame 10, that is, the height of the main shaft 4 is changed. Since the belt surface is wrapped around the main shaft 4, the angle of the belt surface is changed. The belt surface is adjusted upward or downward according to the site environment and ground conditions to ensure that the overall belt surface is horizontal and to ensure the stability of the goods transported on the conveyor belt.

[0032] The self-balancing structure of the conveyor belt surface, through the use of the worm gear screw jack 2, enables the adjustable angle of the conveyor belt surface, expanding its application range; the limitation of the limiting frame 10 satisfies the movement process of the main shaft 4 along the oblique direction of the limiting frame 10, and ensures the stable operation of the conveyor belt surface, resulting in high stability of transported goods. The structure of each component is simple, the arrangement is reasonable, the number of connecting parts is small, reducing the structural complexity and the operating cost.

[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
