[0003] In the prior art, Chinese Patent Publication No. CN220131837U discloses a convenient pallet transfer trolley for coating production, belonging to the technical field of pallet transfer equipment. This utility model includes a trolley body and forks mounted on the trolley body. The forks include two parallel, spaced-apart fork plates. At least one side of each fork plate has a side surface. The side surface is not coplanar with the bearing surface of the fork plate. It also includes a pair of stop structures. Each stop structure includes a base plate fixedly connected to the side surface. The base plate is rotatably connected via a shaft to a stop block that can selectively protrude from the bearing surface of the fork plate, for contacting the side wall of the pallet. This utility model achieves stable pallet transport and has the advantages of good practicality, high safety and reliability, simple structure, and convenient use.

[0004] However, in actual use, this utility model has a limited number of pallets that can be transferred at the same time, making it inconvenient to transfer multiple pallets simultaneously. In the traditional technology, the pallets containing small dough pieces are manually placed into the fermentation chamber for fermentation, which is not only time-consuming and labor-intensive, but also affects the health of workers who stay in the high-temperature fermentation chamber for a long time. Therefore, a pallet transfer trolley is needed. Utility Model Content
