[0026] To facilitate understanding of the technical solution of this utility model by those skilled in the art, the technical solution of this utility model will now be further described in conjunction with the accompanying drawings.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically limited.

[0029] See Figures 1 to 4 This embodiment discloses a belt conveyor, including a support 1, a drive device 2, a drive roller 3, a driven roller 4, a conveyor belt 5, a vertical roller 6, and an annular stop block 7. The support 1 is equipped with the drive device 2 and the rotatable drive roller 3 and driven roller 4. In this embodiment, the drive device 2 is a hydraulic motor, and the output end of the hydraulic motor is coaxially connected to the drive roller 3. Using a hydraulic motor as the power drive not only has the advantages of small size and light weight, but also simple structure, good manufacturability, impact resistance and low inertia, meeting the requirements of portability.

[0030] The driving roller 3 and the driven roller 4 are rotatably fixed on the bracket 1 by a bearing seat structure, which is available on the market.

[0031] The conveyor belt 5 is wound in a ring around the driving drum 3 and the driven drum 4. Vertical rollers 6 that can rotate are fixed at both ends of the support 1 near the driving drum 3 to guide the end of the conveyor belt 5, prevent the conveyor belt 5 from running off-center, and ensure the conveying efficiency of the conveyor.

[0032] The driven roller 4 is fitted with annular blocks 7 at both ends. The opposite side of the annular blocks 7 is concave arc shape. When the tail of the conveyor belt 5 deviates, it contacts the arc-shaped section of the annular blocks 7 on the driven roller 4 and has a frictional effect with the edge of the conveyor belt 5. At this position, a component force is generated towards the middle of the driven roller 4 to achieve automatic correction of the conveyor belt 5, prevent the conveyor belt 5 from running off-track, and ensure the conveying efficiency of the conveyor.

[0033] Furthermore, the support 1 is also fixed with coal retaining plates 9 on both sides along the direction of movement of the conveyor belt 5 by fixing frames 8. The end of the coal retaining plate 9 away from the support 1 is close to the conveyor belt 5 to prevent material spillage during transportation.

[0034] For further details, please refer to [link / reference]. Figure 5 The belt conveyor also includes a tensioning mechanism 10, which includes a linear sliding assembly (not shown), a fixed plate 101, a lead screw 102, and a locking nut 103. The bearing seats at both ends of the driven roller 4 are movable along the direction of the conveyor belt 5 via the linear sliding assembly (not shown) and are mounted on the support 1. The fixed plate 101 is fixed to the support 1. One end of the lead screw 102 is connected to the bearing seat structure at the end of the driven roller 4, and the other end is positioned along the direction of the conveyor belt 5 and passes through the fixed plate 101. Locking nuts 103 are threaded onto the lead screws 102 on both sides of the fixed plate 101. The lead screws 102 are locked onto the fixed plate 101 by the locking nuts 103 on both sides of the fixed plate 101. At the same time, by changing the locking position of the locking nuts 103 on both sides of the fixed plate 101 on the lead screws 102, the position of the bearing seat structure at the end of the driven roller 4 on the linear sliding assembly (not shown in the figure) is changed, thereby realizing the movement of the driven roller 4 and thus realizing the tension adjustment of the conveyor belt 5, preventing the conveyor belt 5 from becoming loose and affecting the transportation efficiency.

[0035] The linear sliding assembly (not shown in the figure) includes a slide rail and a slider. The slide rail is mounted on the support 1 along the direction of the conveyor belt movement, and a slider that can slide is mounted on the slide rail. The bearing seat structure at the end of the driven roller 4 is located between the two sliders.

[0036] Furthermore, handles 11 are welded to both ends of the bracket 1 to facilitate the handling of the belt conveyor. In addition, the weight of the entire belt conveyor is controlled within 200KG.

[0037] In this embodiment, by setting vertical rollers 6 and annular blocks 7 at the beginning and end of the conveyor belt 5 respectively, the ends of the conveyor belt 5 are guided and the tail of the conveyor belt 5 is automatically corrected to prevent the conveyor belt 5 from running off-track and to ensure the conveying efficiency of the conveyor.
