[0040] The pushing assembly 27 comprises a pushing rod 271 located below the upper surface of the fixed frame 21 and a limiting rod 272 located above the fixed frame 21, the limiting rod 272 being provided with a baffle 2723 for limiting the materials, both ends of the pushing rod 271 being rotationally connected with the fixed frame 21 and the mounting rod 26, both ends of the limiting rod 272 being rotationally connected with the fixed frame 21 and the mounting rod 26, the length direction of the top surface of the pushing rod 271 extending along the first direction, one end of the top surface of the pushing rod 271 being located close to the baffle 2723, the other end of the top surface of the pushing rod 271 being located close to the positioning groove 241, the side of the pushing rod 271 close to the limiting rod 272 being located below the materials closest to the baffle 2723, and the driving cylinder 25 driving the mounting rod 26 to drive the end of the pushing rod 271 close to the baffle 2723 and the baffle 2723 to lift to make the baffle 2723 lift above the materials.

[0041] Specifically, the two push rods 271 are located between the two limiting rods 272. In this embodiment, the push rod 271 is preferably an L-shaped rod, the horizontal section of the push rod 271 extends in the first direction, one end of the horizontal section of the push rod 271 is close to the positioning groove 241 and is rotationally connected with the fixed frame 21, the other end of the horizontal section of the push rod 271 is connected with the top end of the vertical section of the push rod 271, and the bottom end of the vertical section of the push rod 271 is rotationally connected with the mounting rod 26. The limiting rod 272 is composed of a horizontal rod 2721, a vertical rod 2722 and a baffle 2723, the horizontal rod 2721 and the vertical rod 2722 are integrally connected, one end of the horizontal rod 2721 is close to the positioning groove 241 and is rotationally connected with the fixed frame 21, the other end of the horizontal rod 2721 is connected with the top end of the vertical rod 2722, and the bottom end of the vertical rod 2722 is rotationally connected with the mounting rod 26.

[0042] When the material pushing assembly 27 blocks the material, the horizontal section of the push rod 271 and the horizontal rod 2721 are in a horizontal state, the baffle 2723 abuts against a steel rod placed on the fixed frame 21 away from the side of the positioning groove 241, and the end of the horizontal section of the push rod 271 away from the positioning groove 241 is located below the steel rod in contact with the baffle 2723; when it is needed to transport the steel rod into the positioning groove 241, the extension end of the driving cylinder 25 is extended, the mounting rod 26 drives the push rod 271 and the limiting rod 272 to lift, the end of the horizontal section of the push rod 271 away from the positioning groove 241 is raised at the same time as the baffle 2723 is raised, the baffle 2723 is raised above the steel rod, the steel rod lifted by the horizontal section of the push rod 271 rolls along the inclined horizontal section of the push rod 271 to the positioning groove 241 until falling into the positioning groove 241.

After the top surface of the horizontal section of the pushing rod 271 and the baffle 2723 are lifted synchronously, the baffle 2723 also rotates, the length of the baffle 2723 in the first direction originally becomes the current vertical distance, that is, the vertical distance of the baffle 2723 decreases, the distance between the baffle 2723 and the top surface of the horizontal section of the pushing rod 271 expands to be greater than the diameter of the steel bar, the baffle 2723 is lifted above the steel bar, and after the horizontal section of the pushing rod 271 starts to contact the steel bar and lift the steel bar, the steel bar can smoothly pass below the baffle 2723. The specific arrangement of the baffle 2723 and the pushing rod 271 is selected according to the actual situation, as long as the distance between the baffle 2723 and the top surface of the horizontal section of the pushing rod 271 is greater than the diameter of the steel bar after the baffle 2723 is lifted above the steel bar and the horizontal section of the pushing rod 271 starts to contact the steel bar and lift the steel bar.
