In actual application, the lifting driving member 3 drives the movable plate 2 to follow the pipe material to lift, so as to follow the change of the height of the material receiving plate 4 relative to the pipe material (especially for non-circular pipes), when the pipe material needs to be supported, the material receiving driving member 5 drives the material receiving plate 4 to be in a horizontal state, and then the movable plate 2 and the material receiving plate 4 follow up and down, when the pipe material needs to be discharged, the material receiving driving member 5 drives the material receiving plate 4 to be in an inclined state, so as to guide the pipe material placed on the material receiving plate 4 to the upstream position of the frame 6, that is, to the position of the driven wheel 72 in the embodiment, since the material storage notch arranged on the conveying chain 73 can be used to limit the movement of the pipe material, with the discharge of the pipe material, under the action of the rotating driving device 8, the conveying chain 73 is rotated from the upstream direction to the downstream direction by means of the driving wheel 71 and the driven wheel 72, so that the pipe material in each material storage notch can be conveyed in the downstream direction one by one, and when the pipe material is conveyed to the end of the downstream, the pipe material in the material storage notch waits to be discharged.

[0032] In the above arrangement, by splitting the material receiving mechanism 10 and the material receiving assembly 20, the occupied space of the combined material receiving rack can be reduced, the manufacturing cost is low, and it is also convenient for delivery and transportation. Furthermore, by arranging the lifting driving member 3, the movable plate 2 and the material receiving plate 4 can follow up and down, and follow up support can be realized; by arranging the material receiving driving member 5, the material receiving plate 4 can be used to support the pipe material when it is horizontal, and can be used for the discharge of the pipe material when it is inclined downward; in addition, the material storage notch formed by the conveying chain 73 and the material limiting block 74 can be used to store the pipe material, so as to avoid the displacement of the pipe material during the conveying of the pipe material, and the stable conveying and discharging of the pipe material can be realized.

Specifically, the lower surface of the second vertical beam 63 is further provided with a bottom plate 13, and the bottom plate 13 is provided with an adjusting foot cup. By using the waist-shaped hole on the fixing sheet 613, a screw is driven to fix the rack 6 to the sidewall of the bed body one by one, and the installation and disassembly are very convenient.

[0040] Please refer to Figure 3 In some embodiments, the end of the crossbeam 61 in the downstream direction is provided with a limiting shaft plate 65 for blocking the pipe from continuing to transport in the downstream direction. The limiting shaft plate 65 can avoid the inertia of the pipe moving in the downstream direction, so that the pipe can easily slide / roll out of the material receiving frame, thereby limiting the pipe to the end in the downstream direction.
