Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drive roller conveying belt, in particular to a drive roller anti-skid conveying belt. BACKGROUND

[0002] The drive roller conveying belt is a continuous conveying equipment with roller shaft driving and belt body carrying as the core. The main roller is driven to rotate by the motor, and the friction between the roller shaft and the belt body drives the conveying belt to circulate, thereby realizing the stable and continuous transfer of materials. With the characteristics of stable structure, strong carrying capacity and low running noise, the drive roller conveying belt is widely used in industrial production and agricultural fields. In the agricultural product industry chain, the drive roller conveying belt is a highly adaptable transfer link that can cover the whole process requirements from field harvesting to processing and packaging. During the harvesting season, it can directly connect the combine harvester and transport truck to realize seamless conveying of wheat, rice and other grains, avoiding the loss caused by manual handling. A single device can convey dozens of tons of materials per hour, greatly improving the field work efficiency. For potato, sweet potato and other tuber crops, anti-skid belt body and flexible baffle can be customized to prevent rolling and knocking during conveying and reduce skin damage.

[0003] The anti-skid measures of the existing drive roller conveying belt are mainly designed for stable state. The surface friction coefficient is increased by driving roller rubber coating, and the grip is enhanced by adding belt body patterns or side anti-skid strips. These methods can deal with slight skidding under normal load, but they are difficult to resist abnormal resistance caused by overload. Heavy load can cause local deformation of the belt body, which destroys the fit with the roller shaft. The friction coefficient of the ceramic rubber coating and other friction increasing structures does not increase with the resistance, so the friction is not enough to resist the sudden increase of load torque.

[0022] As an embodiment of the present application, two support plates 101 are arranged on both sides of the belt 102, and a compression roller 2 is arranged inside the belt 102 and tightly contacts the bottom of the belt 102. The compression roller 2 arranged inside does not occupy the conveying space outside the belt 102, and the compression roller 2 can directly contact the bottom of the belt 102 to apply pressure, thereby efficiently transmitting driving force.
