[0059] It can be understood that, in order to realize the convenient cooperation of the hopper 1 and the feeding rack 2, the shovel openings 13 are arranged at the bottom of the hopper 1 in the embodiment, and the shovel openings 13 are rigid cylindrical structures that can cooperate with the forklift to be lifted. The shape, size and number of the shovel openings 13 can be designed and adjusted according to actual needs, and the shovel openings 13 can be adapted to the forklift. The shovel openings 13 and the hopper 1 can be an integral structure or can be formed by welding. In the embodiment, the shovel openings 13 are arranged to realize the flexible cooperation of the hopper 1 and the forklift. The hopper is lifted to the working platform of the feeding rack 2 by the forklift, and the transfer of the hopper 1 can be completed by using the existing conventional equipment in the production line without the need to increase other equipment, which is convenient, fast and ensures cost control.

[0066] In some embodiments, referring to the accompanying drawings Figure 2 The feeding device provided by the embodiment further includes the limiting frame 6, which includes a first limiting rod 62 and a second limiting rod 63 in specific implementation. The first limiting rod 62 and the second limiting rod 63 are arranged at intervals along the first direction a at the first end of the workbench 4 to form the opening between the first limiting rod 62 and the second limiting rod 63.
