As shown in Figures 1 and 2, the pillar 1 is vertically erected on the base 4 of the conveyor; and the pillar 1 is circled and surrounded by a chain plate rack 2, which plays the role of mainly supporting the transmission chain; To improve the bearing capacity of the chain plate rack 2, a supporting rod 7 is provided on the bottom surface of the chain plate rack 2, and the supporting rod 7 extends to the pillar 1 and is fixed on the pillar 1, so that the chain plate rack 2 is more stable when transporting heavy objects.

One end of the chain plate rack 2 near the bottom of the pillar 1 extends outward to form a material port 201, which can be connected with an ordinary linear conveyor belt to directly transport the goods transported by the linear conveyor belt to the spiral chain plate rack 2. The second end of the chain plate rack 2 near the top of the pillar 1 extends outward to form a second delivery port 202, which can also be connected to a linear conveyor belt.

The extension direction of the first 201 and the second 202 can be adjusted according to the actual transportation situation, and in this embodiment, the first 201 and the second 202 extend in the same direction, so that the goods are from Feeding in one direction can also be discharged from the same direction, which can further save space.

And a return bracket 3 is assembled on the side of the pillar 1. One end of the return bracket 3 is connected with the material conveying port 202 of the chain plate frame 2, and the other end of the return bracket 3 extends to the material conveying in a way that surrounds the pillar 1. After port one 201, it is connected with material transport port one 201 to provide a return path for the transmission chain.
