In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0029] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

[0034] Furthermore, when the belt conveyor is in a non-working state, start adjusting the transition section four-bar linkage roller group. First, loosen the fastening bolts of the brake frame 12, then loosen the brake disc 11, and start adjusting the rocker 9 to allow it to rotate clockwise or counterclockwise around the rotating shaft 16, which will correspondingly drive the rotation of the connecting rod 6 and the side roller 2, so that the rotating end of the side roller 2 can rotate freely clockwise or counterclockwise around the fixed end, so as to adjust the inclination angle of the side roller 2. When the side roller 2 is adjusted to a suitable position, the fastening bolts of the brake frame 12 are locked again.

[0035] Furthermore, by adjusting the adjusting top screw 15 on the roller beam 14, the belt surface and the middle roller 1 can be more closely fitted to ensure a better force effect of the belt.

[0036] Furthermore, both sides of the connecting rod 6 adopt a hinged structure, one end is fixed to one side of the side roller, and the other end is fixed to one side of the rocker 9.

[0037] Furthermore, one end of the rocker arm 9 is fixed to the connecting rod 6 by a hinge structure, and the other end is passed through the rotating shaft 16 , and the rotating shaft 16 is fixed to the rotating bracket 17 .

[0038] Furthermore, the brake disc 11 is mounted on one end of the rotary shaft 16 and locked with fastening bolts, and the brake frame 12 is mounted on the roller beam 14 and locked with fastening bolts, so as to ensure that the brake frame 12 holds the brake disc 11 tightly when not working.

[0039] Furthermore, the adjusting top screw 15 is fixed on the roller beam.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
