The width of the lifting platform 14 only allows one pipe to be lifted each time. The top of the lifting platform 14 is arranged to slope forward, so that the lifted pipe can lean forward against the front wall of the storage bin 11 when rising. The pipe can be lifted by the lifting platform 14 to the entrance of the upper - feeding channel 12. At this time, the pipe can roll into the upper - feeding channel 12. A lifting channel 15 is provided between the upper - feeding landslide 13 and the outlet of the upper - feeding channel 12. The width of the lifting channel 15 only allows one pipe to be lifted.
