[0002] AGV is the abbreviation of automatic guided vehicle. It is an unmanned transportation equipment with automatic navigation, handling, positioning, obstacle avoidance and other functions. AGV plays an important role in the production process of roller presses. It is mainly responsible for the transportation of wheat materials and semi-finished products. Through automated handling and scheduling, it reduces manual operations, improves production efficiency, and reduces cost investment. It is one of the important technologies that are indispensable in modern industrial production. In the workshop of modern production of roller presses, AGV is an indispensable equipment in the workshop.

[0003] In existing AGV transport vehicles, such as Chinese patent application CN113023620A, the composition of the rotating component makes its structure simple and compact, and can realize the smooth rotation of the pallet relative to the chassis for a long time and reliably, effectively reducing the shaking of the pallet, and by adding a second gear, a transmission shaft and a bushing between the first gear and the crank, the reducer only undertakes the output torque task and no longer bears the radial force. The radial force is borne by the second power component. Therefore, the risk of damage to the reducer can be reduced and the reliability of the lifting drive mechanism can be improved.
