The working principle of the invention is as follows: when the conical mixer 1 is used for mixing polyethylene, the polyethylene batching box 2 and the feeding cylinder 3 synchronously perform proportioning operation of raw materials required by the next group of mixing process, after the current mixing operation is finished and output, the polyethylene batching box 2 directly conveys the proportioned raw materials into the conical mixer 1 to continue the next group of mixing operation, and the raw materials do not need to be proportioned and mixed in the processing process, so that the time is saved, and the processing efficiency is remarkably improved; the conical mixer 1 can synchronously mix polyethylene raw materials in various modes, so that the upper raw materials and the lower raw material particles of the conical mixer 1 are fully contacted and mixed, and the mixing efficiency is remarkably improved and the mixing effect is also improved;

when the raw materials are proportioned, the feed hopper 6 continuously enters the circular mixing sieve bin 31, the arc sieve material plate 36 screens raw material particles, the raw material particles meeting the particle size requirement fall into the arc filter bin 32 and enter the polyethylene proportioning bin 2 below, the mixing sieve motor 38 rotates the rotating shaft 33, the rotating shaft 33 drives the partition plate 34 and the shovel plate 35 to rotate, the partition plate 34 and the shovel plate 35 shovel the input raw materials to play a role of stirring the raw materials, so that the sieving efficiency is improved, various raw material particles can be premixed, and the mixing time of the conical mixer 1 is shortened after the raw materials are premixed;

after the current mixing operation in the conical mixer 1 is finished and the raw materials are output, starting a splash-proof receiving mechanism 4, extending and pushing a fixed plate 45 to move upwards by an electric cylinder 44, enabling an output port of a blanking pipe 51 in a material conveying opening and closing mechanism 5 to be positioned in a material receiving sleeve 41 along with the upward movement of the fixed plate 45, continuously lifting the fixed plate 45, continuously moving upwards by a conical jacking block 46 and jacking a conical sealing block 510 upwards by a jacking rod 54, enabling the conical sealing block 510 to move upwards and not seal a conical sealing groove 53 any more, opening the conical sealing groove 53, enabling the raw materials in a polyethylene batching box 2 to enter the conical mixer 1 through the blanking pipe 51, the material receiving sleeve 41 and a telescopic corrugated pipe 42, and helping to prevent the raw materials from splashing in the material conveying process;

meanwhile, the top of the fixing plate 45 finally presses the switch seat 52 to start the scraping and feeding motor 201, the scraping and feeding motor 201 rotates the driving shaft 202, the driving shaft 202 drives each group of loosening connecting rods 205 to rotate through the transmission vertical shaft 203, each group of scraping sheets 206 scrape the inner wall of the polyethylene batching box 2, so that the functions of stirring raw materials and scraping and cleaning the inner wall are achieved, smooth and rapid output of the raw materials is facilitated, and the premixing effect is improved; and the vertical transmission shaft 203 drives the driven shaft 204 to rotate, the cam 207 rotates along with the vertical rotation, under the combined action of the cam 207, the extrusion spring 212 and the energy storage spring 216, the connecting rope 213 is repeatedly loosened and the impact ball 217 is pulled, and the impact ball 217 repeatedly impacts the noise reduction protection pad 218, so that the polyethylene batching box 2 continuously vibrates, the smooth and rapid output of raw materials is further ensured, and the blockage of a discharge hole is avoided.
