Then the transmission shaft is supported on both sides of the support frame and the feeding gear is connected to the transmission shaft through a key and extends into the discharge port of the silo. Finally, the handle of the ratchet assembly is operated to drive the rotation of the ratchet assembly, thereby driving the transmission shaft and the feeding gear to rotate so that the semi-finished steel bars in the tooth groove of the feeding gear are ejected from the discharge port of the silo by the feeding gear and fall onto the pallet. Workers can take the semi-finished steel bars on the pallet.

[0017] This semi-finished steel bar placement rack has the following advantages and effects:

[0018] (1) Simple structure, easy to manufacture and low cost;

[0019] (2) The design of the silo can ensure that the steel bars are neatly arranged to avoid confusion and waste;

[0020] (3) The ratchet assembly is designed to be easily rotated and drive the transmission shaft and the retrieving gear to rotate so as to remove the steel bars from the discharging port;

[0021] (4) The design of the material taking component can ensure that only one steel bar can be taken out at a time, which improves work efficiency;

[0022] (5) The entire rack has good stability and strong load-bearing capacity and can accommodate steel bars of various diameters and lengths;

[0023] (6) It is easy to use, safe and reliable, and can greatly improve construction efficiency and quality. BRIEF DESCRIPTION OF THE DRAWINGS
