The diameter of the feed hole is larger than the outer diameter of the rigid bottom ring. The hole wall of the feeding hole is provided with magnet blocks 51 which correspondingly adsorb the rigid vertical swing rods one by one. The tapered flexible pipe may be located outside the space surrounded by the rigid vertical swing rods or inside the space surrounded by the rigid vertical swing rods, or in this embodiment, the tapered flexible pipe is located inside the space surrounded by the rigid vertical swing rods. The rigid vertical swing rod is connected with the conical flexible pipe to form a framework of the conical flexible pipe, and the magnet blocks adsorb the rigid vertical swing rod to suspend the feeding pipe in the feeding hole. The rigid bottom ring is provided with a plurality of blocking blocks 52 which are distributed along the circumferential direction of the rigid bottom ring, and when the feed pipe is pulled out of the feed hole to the limit position, the blocking blocks abut against the lower end surface of the feed hole to prevent the feed pipe from being pulled out of the feed hole. The upper end of the rigid vertical swing rod is provided with an elbow 53. When the feeding pipe is inserted into the feeding hole to the limit position, the feeding pipe is hooked at the upper end of the feeding hole through the elbow to prevent the feeding pipe from falling into the material storage tank, and specifically: the upper end of the feed port is provided with a large-diameter section, a limit step 61 is formed between the large-diameter section and the feed port, and the elbow is hooked on the limit step when the feed pipe is inserted into the feed port to the limit position. The feeding hole cover is arranged in the large-diameter section in a penetrating mode. The wall of the feed hole is provided with a plurality of horizontal sliding holes which are distributed along the circumferential direction of the feed hole and extend radially, and a horizontal ejector rod 54 and an ejector rod driving spring 55 which drives the horizontal ejector rod to extend out of the horizontal sliding hole are arranged in the horizontal sliding holes in a penetrating way. The magnet blocks are arranged on the horizontal ejector rods in a one-to-one correspondence mode. The upper end face of the storage tank is provided with a plurality of vertical sliding holes which are communicated with the horizontal sliding holes in a one-to-one correspondence manner, and vertical insertion rods 56 are arranged in the vertical sliding holes. The horizontal ejector rod is provided with a driving through hole for inserting the vertical inserted rod, the end face of one end, away from the feeding hole, of the driving through hole is provided with a guide surface 57 which inclines upwards, and when the vertical inserted rod is pulled out of the driving through hole, the guide surface is aligned with the vertical inserted rod. All of the vertical rods are connected to drive ring 58.

Referring to FIG. 6 in conjunction with FIGS. 3-5, the feed tube is withdrawn first and then

When adding pig feed raw materials to the storage tank in, open the feeding handhole door, then upwards pull out the inlet pipe, the outside swing that the pendulum rod used the horizontal axis to make the toper flexible tube open as the axial inlet pipe is erected to the rigidity at the magnet piece to the rigidity under the pendulum rod adsorption makes the conveying pipe 59 insert the upper end at the inlet pipe after the inlet pipe was pulled out, then shift up and erect the inserted bar, make ejector pin drive spring drive ejector pin move towards the import downthehole, thereby the upper end that the pendulum rod was erected to the drive rigidity folds each other and the centre gripping realizes that the upper end of inlet pipe wraps up on the conveying pipe reliably, make pig feed raw materials can not produce more and fall the phenomenon production outside the storage tank. After the pig feed raw materials are added, the vertical insertion rod is pressed downwards, the transmission insertion rod is matched with the guide inclined plane to drive the ejector rod to shrink into the horizontal sliding hole, then the feeding pipe is pressed downwards, the feeding pipe shrinks in the radial dimension under the limiting action of the feeding hole to enter the feeding hole and the storage tank, and then the feeding hole cover is covered.
