This method is time-consuming, labor-intensive and has unstable effects. At the same time, although some existing mechanical deviation correction devices can automatically detect and adjust the belt position, during the deviation correction process, the friction between the belt and the deviation correction roller is large, resulting in severe wear on the bottom of the belt.

[0021] (2) During the process of correcting the belt deviation, the mounting frame is driven to rotate in the opposite direction of the belt deviation, thereby causing the material on the belt to tilt and reduce the weight of the material on the belt. Subsequently, the adjusting roller is driven to rotate, and the adjusting roller and the belt are subjected to rolling friction to drive the belt to move, so that the friction force and wear of the belt during the correction process are reduced, thereby reducing damage to the belt and increasing the service life of the belt.

[0022] (3) When the conveyor belt is in operation, the belt drives the adjusting tube and the guide roller to rotate, thereby driving the first mounting tube and the second mounting tube to rotate.

A third telescopic rod 295 is fixedly connected to the support frame 23, and a trigger delay switch 296 is fixedly connected to one end of the third telescopic rod 295. A fifth spring 297 connected to the support frame 23 is fixedly sleeved on the outer surface of the third telescopic rod 295. The trigger delay switch 296 is connected to the electric hydraulic push rod 191 and the adjusting drive mechanism. A return oil pipe 31 fixedly connected to the oil storage tank 26 is fixedly connected to the outer surface of the first connecting pipe 27, and an electromagnetic valve 32 is provided on the return oil pipe 31.

[0045] The adjustment drive mechanism includes a transmission rack 41 slidably connected to the transmission plate 11, one side of the transmission rack 41 is meshedly connected with a one-way gear 42 fixedly sleeved with the mounting shaft 18, a second hydraulic oil tank 43 is fixedly connected in the adjustment tube 4, a second push plate 44 is slidably connected in the second hydraulic oil tank 43, one side of the second push plate 44 is fixedly connected to a fourth spring 45 fixedly connected to the second hydraulic oil tank 43, the other side of the second push plate 44 is fixedly connected to a second transmission column 46, one side of the second transmission column 46 is fixedly connected to a second transmission disk 47, and one side of the second transmission disk 47 is connected to the transmission rack 41 through a connecting column Then, the second hydraulic oil tank 43 is connected to the first mounting tube 3 through a pipeline, the mobile transmission of the first mounting tube 3 is connected with a driving mechanism connected with the mounting frame 2, the driving mechanism is connected with the trigger delay switch 296, the driving mechanism includes a driving box 51 fixedly connected with the mounting frame 2, an electric hydraulic rod 52 is fixedly connected in the driving box 51, one end of the electric hydraulic rod 52 is fixedly connected with a third push plate 53 fixedly connected with the driving box 51, the electric hydraulic rod 52 is connected with the trigger delay switch 296, and one side of the driving box 51 is fixedly connected with a fourth connecting pipe 54 rotatably connected to the first mounting tube 3 through a pipeline.

[0046] When the belt deviates, the belt contacts the transmission roller 24 in the support frame 23, thereby driving the transmission roller 24 to rotate, and the transmission roller 24 drives the oil pump 25 to rotate, and the oil pump 25 pumps the oil in the oil storage tank 26 into the second connecting pipe 28 through the first connecting pipe 27, and then the second connecting pipe 28 passes the oil into the first hydraulic oil tank 290 through the third connecting pipe 29, and then pushes the first push plate 291 in the first hydraulic oil tank 290 to move, and the first push plate 291 drives the first transmission column 293 to move, and the first transmission column 293 drives the first transmission disc 294 to move, and the first transmission disc 29 4 drives the transmission plate 11 to move. When the correction is completed, the belt no longer contacts the transmission roller 24. At this time, the oil pump 25 stops working, and then the electromagnetic valve 32 on the oil return pipe 31 is opened. Then the first push plate 291 moves under the action of the third spring 292, and the oil returns to the oil storage tank 26 through the oil return pipe 31. Then the electromagnetic valve 32 is closed. At the same time, the belt drives the transmission roller 24 to rotate, triggering the trigger delay switch 296 on the support frame 23. At this time, the trigger delay switch 296 starts to start, and the electric hydraulic rod 52 is opened to work. At the same time, the electric hydraulic rod 52 drives the oil in the drive box 51. The third push plate 53 reciprocates, and the third push plate 53 passes the oil in the drive box 51 into the first mounting pipe 3 through the fourth connecting pipe 54. Then the first mounting pipe 3 passes the oil into the second hydraulic oil tank 43 through the pipeline. When the third push plate 53 moves downward, the second hydraulic oil tank 43 is filled with oil, driving the second push plate 44 and the second transmission column 46 to move outward. When moving upward, the second hydraulic oil tank 43 is sucked to drive the second push plate 44 and the second transmission column 46 to move inward. At the same time, the second push plate 44 in the second hydraulic oil tank 43 is driven by the cooperation of the fourth spring 45. The second hydraulic oil tank 43 performs reciprocating movement, the second push plate 44 drives the second transmission column 46 and the second transmission plate 47 to perform reciprocating movement, the second transmission plate 47 drives the transmission rack 41 to perform reciprocating movement, and the transmission rack 41 drives the one-way gear 42 to rotate (the one-way gear 42 can only drive the installation shaft 18 to rotate when it rotates forward, and the reverse rotation does not drive the installation shaft 18 to rotate. For example, the one-way gear 42 design on the existing rear wheel axle of a bicycle is a prior art and will not be described in detail here), thereby driving the installation shaft 18 and the adjusting roller 19 to rotate toward the center position of the mounting frame 2.

[0047] When the belt is offset, the offset belt drives the hydraulic transmission control mechanism to work. At this time, the hydraulic transmission control mechanism starts to control the electric hydraulic push rod 191 to move. The electric hydraulic push rod 191 drives the mounting frame 2 on this side to rotate upward, and at the same time drives the belt to move upward, tilting the material on the belt to one side, reducing the weight borne by this side of the belt, and at the same time the hydraulic transmission control mechanism drives the transmission plate 11 to move, and the transmission plate 11 drives the first transmission block 12 to move, and the first transmission block 12 pushes the second transmission block 13 to move upward, and the second transmission block 13 drives the connecting plate 14 and the mounting frame 17 on the connecting plate 14 to move outside the adjusting groove 190 on the adjusting tube 4, so that the adjusting roller 19 contacts the bottom of the belt. At this time, the belt continues to move and drives the adjusting tube 4 to rotate. At the same time, the hydraulic transmission control mechanism drives the adjusting drive mechanism to operate, and the adjusting drive mechanism belt The movable mounting shaft 18 rotates unidirectionally toward the center position of the mounting frame 2, and the mounting shaft 18 drives the adjusting roller 19 to rotate. At this time, the adjusting roller 19 rubs against the bottom of the belt to drive the belt to move toward the center position of the mounting frame 2. At the same time, the material on the belt is driven by the electric hydraulic push rod 191 to drive the mounting frame 2 to rotate to the other side, so that a part of the material is moved to the center position, so that the pressure on the belt on this side is reduced, and the friction between the belt and the adjusting roller 19 is reduced, which facilitates the movement of the belt and moves it to the center position, while reducing damage to the bottom of the belt. At the same time, during the movement, the belt and the adjusting roller 19 on the adjusting tube 4 roll and rub, so that the friction force on the belt during the deviation correction process is small, and the wear is low, thereby reducing damage to the belt, thereby realizing automatic correction of the offset belt, and at the same time, the loss of the belt during the correction process is small, thereby increasing the service life of the belt.

[0048] Implementation Three

[0049] Based on Example 2, please refer to Figure 1 and Fig.10 As shown, the belt cleaning mechanism includes a first gear 61 fixedly connected to the first mounting tube 3 and the second mounting tube 5, the outer surface of the first gear 61 is meshingly connected to the second gear 62, the middle of the second gear 62 is fixedly connected to the first rotating shaft 63 rotatably connected to the mounting frame 2, the outer surface of the first rotating shaft 63 is connected to the second rotating shaft 64 connected to the mounting frame 2 through a transmission wheel and a transmission belt, one end of the second rotating shaft 64 is fixedly connected to a cleaning roller 65, and a plurality of cleaning brushes 66 are fixedly connected to the cleaning roller 65.

[0050] The belt moves on the adjusting tube 4 and the guide roller 6, thereby driving the adjusting tube 4 and the guide roller 6 to rotate, and the adjusting tube 4 and the guide roller 6 drive the first mounting tube 3 and the second mounting tube 5 to rotate, and the first mounting tube 3 and the second mounting tube 5 drive the first gear 61 to rotate. Since the first gear 61 is designed to be larger than the second gear 62, the first gear 61 drives the second gear 62 to rotate quickly, and the second gear 62 drives the first rotating shaft 63 to rotate. The first rotating shaft 63 drives the second rotating shaft 64 to rotate through the transmission wheel and the transmission belt, and the second rotating shaft 64 drives the cleaning roller 65 and the cleaning brush 66 to rotate. The cleaning brush 66 cleans the dust at the bottom of the belt, thereby automatically cleaning the dirt adhered to the bottom of the belt, reducing the contact between the dirt at the bottom of the belt and the conveying roller, causing the conveying force to be offset, causing the belt to offset, thereby reducing the incidence of belt offset and improving the stability of the conveyor.

[0051] The working principle of the present invention is as follows: by installing multiple correcting devices on the belt conveyor, that is, fixing multiple mounting plates 1 on the belt conveyor, the belt is then fitted onto the two adjusting tubes 4 and the guide rollers 6 in the mounting frame 2. When the conveyor is in conveying operation and the belt deviates, the correcting device automatically corrects the belt in a timely manner. At the same time, the correcting device reduces the wear on the belt during the correction process, thereby increasing the service life of the belt. At the same time, when the belt drives the adjusting tube 4 and the guide roller 6 to rotate, it drives the first mounting tube 3 and the second mounting tube 5 to rotate. The first mounting tube 3 and the second mounting tube 5 drive the belt cleaning mechanism to rotate. The belt cleaning mechanism cleans the dirt at the bottom of the belt in a timely manner to prevent the dirt adhering to the belt from fitting onto the conveying rollers, thereby causing the belt to deviate during the conveying process, thereby improving the stability of the belt conveying.

[0052] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
