[0026] In addition, if Figure 4 As shown, this embodiment also provides a small package box bulk forklift loading device, including a fork tine 21 connected to a forklift mast 2, and the split loading special pallet as described above, wherein the shape of the fork tine 21 is adapted to the fork tine slot 13, and the forklift mast 2 slides down and lands and is inserted into the fork tine slot 13 of the split loading special pallet. It also includes a pressing mechanism 3 arranged on the mast 2 for pressing the package box 5 downward, and a pushing mechanism 4 arranged on the mast 2 for pushing the package box 5 forward.

[0027] The clamping mechanism 3 includes a slide rail 32 fixedly and vertically arranged on the forklift mast 2, and a clamping plate 31 slidably mounted on the slide rail 32 through a sleeve 311. The clamping plate can be set to be relatively long, which can be much longer than the length of the pallet, but not more than the length of the car body at most. Generally, the length of the clamping plate is twice as long as the pallet; it also includes a cylinder 33 with one end arranged on the clamping plate 31 and the other end arranged on the slide rail or the forklift mast 2.

[0028] In some embodiments, Figure 4 As shown, the pushing mechanism 4 includes a push plate 42, and a cylinder 41 with one end arranged on the push plate 42 and the other end arranged on the forklift mast 2. Figure 4 The middle push mechanism has pushed the goods forward.

[0029] In other embodiments, Figure 5 , 6 As shown, Figure 5 The middle push mechanism has pushed the goods forward. Figure 6 The pushing mechanism does not push the goods forward and is in the initial state. The pushing mechanism 4 includes a push plate 42, a slide 44, a scissor fork telescopic mechanism 43, and a second cylinder 41. The slide 44 is fixedly arranged vertically on the forklift door frame 2. The scissor fork telescopic mechanism 43 includes a connecting rod group 432 connected by a plurality of connecting rods that are cross-rotated and connected, and a horizontal shaft 431 arranged in the slide 44.
