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. A plurality of vertical sliding holes which are communicated with the horizontal sliding holes in a one-to-one correspondence way are arranged on the upper end surface of the bin body, and vertical inserting 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 vertical bayonet rods are connected to the drive ring 58.

Referring to fig. 9 in combination with fig. 6 to 8, when the additive is fed into the silo, the feeding hole cover is opened, the feeding pipe is pulled upwards, the rigid vertical swing rod swings outwards with the horizontal shaft as the axial feeding pipe under the adsorption effect of the magnet block on the rigid vertical swing rod after the feeding pipe is pulled out, so that the tapered flexible pipe is opened, the feeding pipe 59 is inserted into the upper end of the feeding pipe, then the vertical insertion rod moves upwards, the ejector rod driving spring drives the ejector rod to move towards the inlet hole, and therefore the upper ends of the rigid vertical swing rods are driven to be folded and clamped on the feeding pipe, the upper end of the feeding pipe is reliably wrapped on the feeding pipe, and the phenomenon that the pig feed raw materials fall outside the silo is avoided. After adding pig feed raw materials, push down perpendicular inserted bar for defeated inserted bar cooperation direction inclined plane drive ejector pin contracts to the horizontal slide opening in, then pushes down the inlet pipe, thereby makes the inlet pipe produce radial dimension shrink and get into feed port and the internal of storehouse under the limiting action of feed port, then cover the feed hole lid can.
