[0028] The discharge conveying track 11 of the feeding vibration plate 1 is connected to the first conveying track 2. The discharge end of the first conveying track 2 is provided with a push opening 21 and a discharge opening 22 which are arranged opposite to each other. The second conveying track 3 is located beside the discharge opening 22 on the first conveying track 2, and the discharge opening 22 is connected to the feed opening of the second conveying track 3 correspondingly. The first pushing mechanism 14 is arranged beside the push opening 21. The first conveying track 2 and the second conveying track 3 are both made of metal. The feeding vibration plate 1 is conventionally used in the prior art. It will not be described in detail here. During operation, the loading vibration plate 1 is used to load batches of metal pipes one by one and transport them to the first conveying track 2 via the discharge conveying track 11. Then, during the continuous loading process, the metal pipes are transported to the discharge opening 22 of the first conveying track 2. Then, the first pushing mechanism is started to push the metal pipes at this position and displace them and enter the transfer channel 20 of the second conveying track 3 through the discharge opening.
