the first lead screw 120 drives the first gear 118 to rotate, so that the second gear 119 meshed with the first gear 118 is driven to rotate, and the first shaft 121 and the first lead screw 120 are driven to synchronously rotate;
in the rotation process of the first shaft 121, the third sliding groove 123 on the outer side wall of the first shaft 121 and the second sliding block 124 on the second lead screw 122 slide relatively, so that the second sliding block 124 slides along the third sliding groove 123, the right end of the second lead screw 122 is gradually inserted into the first connecting block 128 and is in threaded transmission with the second threaded hole in the first connecting block 128, and the sleeve 105 is driven to slide towards the direction close to the furnace mouth of the reduction tank 4 by the first shaft 121;
when the sleeve 105 moves to the leftmost end of the second screw 122, the sleeve 105 gradually disengages from the second screw 122, the first shaft 121 and the second screw 122 at this time idle, the sleeve 105 stops sliding on the bracket 101, and the left end of the sleeve 105 at this time stretches into the interior of the sleeve 105;
the material taking cylinder 104 continuously slides in the sleeve 105 along the first straight sliding groove 110 through the third sliding block 109 on the material taking cylinder 104, when the third sliding block 109 slides to the rotary sliding groove 111, the material taking cylinder 104 rotates spirally relative to the sleeve 105, so that the first material taking plate 112, the second material taking plate 113, the third material taking plate 114 and the fourth material taking plate 115 are driven to be unfolded in sequence, the left end of the material taking cylinder 104 at the moment just moves to the leftmost end in the reduction tank 4, and the first material taking opening 127 on the sleeve 105 is just aligned with the second material taking opening 108 on the material taking cylinder 104;
the feeding machine inputs materials into the material taking cylinder 104 through the aligned first material taking opening 127 and the aligned second material taking opening 108, the second motor 125 is started to drive the auger 126 to rotate in the material taking cylinder 104, and the materials in the material taking cylinder 104 are conveyed into the reduction tank 4;
the first motor 103 is reversed to drive the material taking cylinder 104 to move rightwards, and because the reduction tank 4 is in a horizontal state at this time, slag in the reduction tank 4 is concentrated at the bottom of the reduction tank 4, and the slag at the bottom of the reduction tank 4 is scraped through the first material taking plate 112, the second material taking plate 113, the third material taking plate 114 or the fourth material taking plate 115, so that the purpose of scraping slag while feeding is realized.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions will be apparent to those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered to be within the scope of the present invention.
