By arranging the arc seat 6 on the connecting rod 5, the arc seat 6 will rotate with the connecting rod 5, and the arc seat 6 will rotate to the position of the slide bar 13. The arc seat 6 will gradually push the slide bar 13 and then move away from the slide bar 13 as the connecting rod 5 rotates. When the arc seat 6 pushes the slide bar 13, the slide bar 13 will drive the push plate 16 to move to the edge of the placement platform 17, and then push the steel bar away. After the arc seat 6 moves away from the slide bar 13, the slide bar 13 will be driven by the reset spring 12 to reset, and the push plate 16 can be reset, so as to realize the next steel bar placement, and the steel bar can be pushed to the ladder platform 18 in sequence.

[0035] A convex seat 11 is welded on the input end of the slide bar 13, and the convex seat 11 is arranged vertically on the slide bar 13. The convex seat 11 overlaps the inclined surface of the ramp 7. The slide bar 13 and the convex seat 11 are arranged in an L-shape as a whole. A push plate 16 is welded on the other end of the slide bar 13, and the slide bar 13 is arranged vertically on the push plate 16. The push plate 16 is arranged along the length of the placement platform 17. By arranging the convex seat 11 on the slide bar 13, the convex seat 11 can first contact the ramp 7 of the arc seat 6, and when the inclined surface of the ramp 7 contacts the convex seat 11, it is convenient to push the slide bar 13, so as to realize the extension and retraction of the slide bar 13, and the slide bar 13 can drive the push plate 16 to reciprocate.

The top ladder 19 can reciprocate to push up the steel bars on the ladder platform 18, and the steel bars can move downward one by one and finally fall onto the conveyor bed 1. While the top ladder 19 moves up and down, the driving roller 15 and the push plate 16 will also continue to move. When the steel bars are continuously conveyed to the position of the driving roller 15, the steel bars will fall onto the placement table 17 in turn. After being pushed by the push plate 16, the steel bars can move to the position of the ladder platform 18, thereby realizing the sequential conveying of the steel bars.
