[0037] The common structure of the belt conveyor is three-roller structure, the rollers on both sides are inclined upward, so that the both sides of the belt are higher than the middle area. When the belt conveyor transports upward or downward, the rollers are arranged correspondingly to limit the belt into horizontal section and inclined section. In actual application, it is found that the position between the horizontal section and the inclined section, the belt turning part is deformed, the state of the both sides being high and the middle being low defined by the previous rollers is tightened upward, which causes the material to scatter and overflow. The existing solution is to set a pressure roller device at the belt turning part, and the pressure roller of the pressure roller device is used to press the belt to avoid the belt being tightened upward. However, a new problem is caused, because the pressure roller device is set at the turning part, the sealing guide chute of the horizontal section and the inclined section of the belt conveyor plays a sealing and anti-overflow role, and the sealing guide chute is disconnected at the pressure roller device, so that the belt at the pressure roller device is exposed, and the dust generated in the material conveying process is diffused to the external environment.

[0038] Therefore, the utility model provides a pressure roller device of anti-overflow, which can be applied to the belt conveyor to effectively solve the above problems. Wherein, the belt conveyor includes a rack 500, a belt conveying assembly 510 and a sealing guide chute 520, the belt conveying assembly 510 includes a belt, a roller assembly and a driving mechanism, the belt includes a horizontal section and an inclined section and forms a turning part between the both, the horizontal section and the inclined section of the belt are correspondingly provided with the sealing guide chute 520, and the two sealing guide chutes 520 are spaced apart at the belt turning part.
