DETAILED DESCRIPTION

[0016] The present invention will be further explained and illustrated below with reference to the accompanying drawings:

[0017] For example, see Figure 1-Figure 2 , a belt conveyor anti-deviation device includes a bracket 1, a first base plate 2 is connected to the bracket 1 by bolts, a first guide roller 5 is arranged above the middle of the first base plate 2, and a second bracket 6 is arranged at both ends of the first base plate 2, a support block 7 is rotatably connected in the second bracket 6, a guide wheel 8 is rotatably connected to the inner side of the support block 7, a spring 10 is arranged at the bottom of the support block 7, at least two U-shaped rings 11 are provided on the first base plate 2 below the spring 10, and the bottom of the spring 10 is connected to one of the U-shaped rings 11 through a hook, the second base plate 3 is connected to the brackets 1 on both sides of the first base plate 2 by bolts, a second guide roller 14 is arranged above the middle of the second base plate 3, and inclined rollers 15 are arranged on both sides of the second guide roller 14.

[0018] Positioning grooves are respectively provided at the bottom of the first bottom plate 2 and the second bottom plate 3 at positions corresponding to the bracket 1 , the positioning grooves are sleeved on the bracket 1 , and the first bottom plate 2 , the second bottom plate 3 and the bracket 1 are fixed by bolts.

[0019] First brackets 4 are provided at both ends of the first guide roller 5 . The first brackets 4 are provided on the first bottom plate 2 , and the first guide roller 5 and the first brackets 4 are rotatably connected together.

[0020] The guide wheel 8 is distributed in an inclined shape, and a circular tray 9 is provided at the outer end of the guide wheel 8 .

[0021] A third bracket 12 is provided at both ends of the second guide roller 14 , and the second guide roller 14 and the third bracket 12 are rotatably connected together. An outer support plate 13 is provided at both ends of the second bottom plate 3 , and an inclined roller 15 is rotatably connected between the outer support plate 13 and the third bracket 12 .

[0022] In the above description, the position of the first base plate is determined according to the usage of the belt.

[0023] In the above description, by arranging the oblique rollers at both ends of the second guide roller, a certain limiting effect is also played, and the use of the guide wheel can provide double protection for the belt.

[0024] In the above description, since the support block and the second bracket are rotatably connected together, the inclination angle of the support block can be adjusted by changing the position of the U-shaped ring.
