The utility model discloses a loader and its conveying system. The loader consists of a tube body, the tube tail of the tube body is connected with the tube seat, and the tube seat is connected with the three-way valve through the connecting tube. The tube body is composed of a skeleton tube, an inner protecting tube and an outer protecting tube. The skeleton pipe is a solenoid with equal diameter and pitch. Alternatively, the skeleton tube is a grid tube with equal diameter and density. The spiral pipe with equal diameter and pitch is made up of cylindrical steel wire winding, and the spiral pitch of the spiral pipe is equal. The inner surface of the spiral pipe with equal diameter and pitch is cylindrical, while the outer surface of the spiral pipe with equal diameter and pitch is cylindrical. The grid pipe with equal diameter and density is composed of cylindrical steel wires interwoven by equal density. The conveying system includes sheath, expander, conveyor rod and loader. The loader is the loader as described above. The rigidity of the loader tube body of the conveying system is large, and it is easy to connect with the sheath tube, and the strength is also large. It is not easy to be braced by the blocker, which is conducive to the loading and conveying of the blocker.
