[0026] The support assembly is arranged on the mounting base 1, and the support assembly is used for rolling support of the conveyor belt; the position of the mounting member 2 on the mounting base 1 is fixed by bolts 7, and the spacing between the two groups of mounting members 2 can be adjusted by providing a long slot hole on the mounting member 2. The size of the deviation-correcting conveyor belt is increased by adjusting the spacing between the two groups of mounting members 2. The swing member 4 is rotatably supported on the mounting member 2 through the positioning column 3, and the deviation-correcting roller 6 is rotatably supported on the swing member through the mounting column 5. After the conveyor belt is deviated by the deviation-correcting roller 6, the swing member 4 is driven to rotate around the positioning column 3. The reset force is provided by the reset assembly to enable the deviation-correcting roller 6 to correct the conveyor belt. Here, the deviation-correcting roller 6 limits the conveyor belt, and the conveyor belt is supported by the support assembly to ensure long-distance transportation of materials. The structure is simple and the deviation-correcting timeliness is high.

[0027] like Figures 1 to 4As shown, as a preferred solution, the reset assembly includes a connecting member 8 arranged on the mounting member 2, an adjusting assembly is arranged on the connecting member 8, a spring 9 is arranged on the adjusting assembly, the other end of the spring 9 is arranged on the swing member 4, a first limiter 10 is arranged on the swing member 4, the spring 9 is sleeved outside the first limiter 10, a blocking member 11 is arranged on the mounting member 2, the swing member 4 is in contact with the blocking member 11, and the blocking member 11 and the connecting member 8 are respectively located at both ends of the swing member 4;

[0029] like Figures 1 to 4 As shown, as a preferred solution, the support assembly includes a fixing member 15 arranged in the middle of the mounting base 1, auxiliary components are symmetrically arranged on the mounting base 1 at both ends of the fixing member 15, a transmission member 16 is arranged on the fixing member 15, and a support roller 17 is rotatably arranged on the transmission member 16, and the support assembly is located on the side where the barrier member 11 is arranged on the swing member 4; the fixing member 15 is installed at the center of the mounting base 1, providing a solid foundation for the entire support assembly, ensuring stability during long-distance and heavy-load material transportation, and reducing the conveyor belt deviation or wear caused by the unstable support structure. Auxiliary components are provided to achieve precise centering support of the conveyor belt. This design not only balances the pressure distribution on both sides of the conveyor belt, but also improves the smoothness of the conveyor belt operation, effectively reduces the vibration and noise caused by off-center loading during transportation, and extends the service life of the conveyor belt and the entire system. The combined design of the transmission member 16 and the support roller 17 enables the support component to flexibly adapt to slight changes in the conveyor belt during operation, such as tension fluctuations or slight offsets. The rotation of the support roller 17 reduces the direct friction between the conveyor belt and the support point, protects the conveyor belt from unnecessary damage, and ensures the continuity and efficiency of material transmission.

[0030] like Figures 1 to 4As shown, as a preferred embodiment, the auxiliary component includes two groups of auxiliary parts 18 arranged on the mounting base 1, the two groups of auxiliary parts 18 are symmetrically arranged at both ends of the fixing part 15, an auxiliary roller 19 is rotatably arranged on the auxiliary part 18, threaded rods 20 are rotatably arranged in the through holes at both ends of the fixing part 15, the threaded rods 20 are arranged in the threaded inner holes of the auxiliary part 18, a positioning slide rail 25 is arranged on the mounting base 1, the positioning slide rail 25 is symmetrically arranged at both ends of the fixing part 15, the positioning slide rail 25 is arranged in the inner groove of the auxiliary part 18, and the rotation axis of the auxiliary roller 19 is arranged at an angle of 90° to the rotation axis of the deviation correcting roller 6; by symmetrically arranging the auxiliary parts 18 at both ends of the fixing part 15 and rotatably configuring the auxiliary rollers 19 on the auxiliary parts, an auxiliary support structure for both sides of the conveyor belt is formed, which not only significantly enhances the stability of the overall frame, but also improves the stability of the overall frame through the auxiliary rollers and the deviation correcting roller shape. The 90° cross layout realizes the fine centering adjustment of the conveyor belt and greatly improves the correction accuracy and efficiency. The threaded rod 20 and the threaded design inside the auxiliary part 18 allow the position of the auxiliary part to be adjusted by rotating the threaded rod according to actual working conditions, thereby adjusting the support strength and position of the auxiliary roller 19 on the conveyor belt. This dynamic adjustment mechanism can effectively cope with the tension changes or deviations that may be encountered in the operation of the conveyor belt, and maintain the continuity and smoothness of the conveying process. The auxiliary roller 19 and the axis of the correction roller 6 are set at a 90° angle, which ensures that the conveyor belt is balanced and effectively supported in two directions, reduces the direct friction of the conveyor belt during the correction process, reduces the risk of wear, protects the conveyor belt material, and extends its service life. At the same time, it reduces the heat and noise generated by friction, creating a safer and more environmentally friendly working environment.

[0031] like Figures 1 to 4 As shown, as a preferred solution, a driving shaft 21 is arranged in the mounting hole of the mounting base 1, a driving bevel gear 22 is coaxially arranged on the driving shaft 21, a driven bevel gear 23 is coaxially arranged on the threaded rod 20, the driving bevel gear 22 is meshed and transmission-connected with two sets of driven bevel gears 23, and an adjusting wheel 24 is coaxially arranged on the driving shaft 21; by inserting the driving shaft 21 into the mounting hole of the mounting base 1, and installing the driving bevel gear 22 thereon, the threaded rod 20 is driven to rotate by the meshing of the driving bevel gear 22 and the driven bevel gear 23, and then the relative positions of the two sets of auxiliary parts 18 and the fixing part 15 are synchronously adjusted, and the design of the adjusting wheel 24 on the driving shaft 21 provides an intuitive and simple adjustment means for the operator, and the speed and direction of the driving shaft 21 can be easily adjusted manually. This design enhances the adaptability of the device, and can make real-time compensation according to the changes in the conveyed material or the aging degree of the conveyor belt to maintain the optimal support and deviation correction state.

[0032] like Figures 1 to 4 As shown, as a preferred solution, its working process is as follows:

[0033] First, install the correcting device at the key position of the long-distance belt conveyor, fix the mounting part 2 at the predetermined position of the mounting base 1 by means of bolts 7, and use the long slot holes on the mounting part 2 to adjust the spacing between the two sets of mounting parts 2 to adapt to conveyor belts of different widths. Then, ensure that the correcting roller 6 is located at the edges of both sides of the conveyor belt, and prepare to correct the deviation of the conveyor belt. After the conveyor is started, the conveyor belt begins to carry materials and run. If the conveyor belt deviates, the conveyor belt on the deviated side will contact the correcting roller 6. Since the rotation center of the correcting roller 6 is inconsistent with the center line of the conveyor belt, the contact will generate a lateral force, driving the swinging part 4 to rotate around the positioning column 3, thereby changing the position of the correcting roller 6 and applying a reverse force to the conveyor belt to cause the conveyor belt to return to the center line. When the correcting action is completed, the reset component will function to return the correcting roller 6 to the initial position or the preset position as required, thereby ensuring the accuracy and timeliness of the correcting action.

[0034] The long-distance belt conveyor deviation correction device of the utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effects.
