[0019] Embodiment 2: The technical solution of this embodiment different from that of Embodiment 1 includes: The shielding mechanism 5 includes a number of single-headed stepping motors 51.

The second winding wheels 52 are all drivingly connected to the second connecting lines 53. The other sides of the second connecting lines 53 are fixedly connected to the folding doors 54. The upper ends of the folding doors 54 are slidably connected to the inner chute of the cross plate through pulleys. The other sides of the folding doors 54 are fixedly connected to the telescopic dampers 55 with springs sleeved outside symmetrically arranged. The other sides of the telescopic dampers 55 and the springs are fixedly connected to the vertical plate. A number of telescopic cylinders with push plates are fixedly connected inside the storage box 1 separated by the cross plate and the vertical plate.

[0020] When in use, when the materials enter the inside of the storage box 1, the single-headed stepping motors 51 in different compartments inside the storage box 1 are started through the controller. The output end of the single-headed stepping motor 51 drives the second winding wheel 52. When the second winding wheel 52 rotates, it winds up the second connecting line 53. When the second connecting line 53 is wound up, it pulls the folding door 54. The folding door 54 will stably close the compartments inside the storage box 1 under the sliding limit of the inner chute of the cross plate through the pulley, so as to shield and limit the materials. When the materials need to be taken out, the telescopic cylinders inside different compartments are started through the controller. When the telescopic cylinders are started, the output ends drive the push plates to move. When the push plates move, they will push the materials from the corresponding compartments inside the storage box 1 to the support plate 34, and then the feeding is carried out through the limiting mechanism 3 and the lifting mechanism 4, improving the overall loading and unloading efficiency.
