When the device is actually used, materials are poured into the feeding groove a2 and enter the multi-particle-size material feeding device a1 along the feeding groove a2, then the multi-particle-size material feeding device a1 conveys the materials to the material processing host a4 through the discharging pipe a3, and the material processing host a4 processes the materials; the assembly line type operation is high in processing efficiency and beneficial to automatic production.

Based on the above embodiment, further, the multi-particle-size material feeding device a1 includes a supply circular pipeline 1, a buckling-pressing type driving traction mechanism 2, a tensioning driven chain wheel mechanism 3 and a plurality of reducing scraper mechanisms 4;

the annular supply pipeline 1 is provided with a feed inlet 11 and a discharge outlet 12, the feed inlet 11 is connected with the feed chute a2, and the discharge outlet 12 is connected with the discharge pipe a 3; the buckling and pressing type driving traction mechanism 2 and the tensioning driven chain wheel mechanism 3 are respectively arranged at two ends of the supply annular pipeline 1, and the buckling and pressing type driving traction mechanism 2 is arranged close to the discharge hole 12; the reducing scraper mechanisms 4 are uniformly distributed in the supply annular pipeline 1 and are connected end to end sequentially through traction steel wires 5; the traction steel wire 5 is wound on the buckling type driving traction mechanism 2 and the tensioning driven chain wheel mechanism 3; the tension driven chain wheel mechanism 3 can adjust the tension of the traction steel wire 5;

the plurality of reducing scraper mechanisms 4 respectively comprise a reducing scraper body 41, a reducing guide cylinder 42, a reducing sliding shaft 43, a reducing reset spring 44 and a plurality of reducing scraper units 45 which are distributed in a circumferential array; the reducing scraper body 41 is disc-shaped, and a working cavity is arranged in the reducing scraper body 41; the reducing guide cylinder 42 is arranged in the center of the reducing scraper body 41 in a penetrating manner; one end of the reducing guide cylinder 42 is connected with the traction steel wire 5; a plurality of reducing guide holes which are in one-to-one correspondence with the plurality of reducing scraper units 45 are arranged on the circumferential wall of the reducing guide cylinder 42 at equal intervals along the circumferential direction; the reducing sliding shaft 43 is arranged in the reducing guide cylinder 42 in a sliding manner, and one end of the reducing sliding shaft extends out of the other end of the reducing guide cylinder 42 and then is connected with the traction steel wire 5; the other end of the reducing sliding shaft 43 is provided with a plurality of reducing connecting lugs at equal intervals along the circumferential direction; the reducing connecting lugs penetrate through the reducing guide holes in a one-to-one corresponding manner; the reducing return spring 44 is sleeved on the outer wall of the reducing sliding shaft 43, and two ends of the reducing return spring are respectively abutted against the other end of the reducing sliding shaft 43 and the reducing guide cylinder 42;

each reducing scraper unit 45 comprises a transmission assembly 451 and a fan-shaped slider unit 452; the transmission assembly 451 is correspondingly arranged in the working cavity, and one end of the transmission assembly 451 is correspondingly hinged to the reducing connecting lug; the fan-shaped sliding block unit 452 is arranged on the circumferential surface of the reducing scraper body 41, and the fan-shaped sliding block unit 452 is hinged with the other end of the transmission assembly 451; two ends of the fan-shaped slider unit 452 are respectively overlapped and attached to one end of the fan-shaped slider unit 452 of the two adjacent reducing scraper units 45.

The working mode of the embodiment is as follows: when the device works, materials are placed into the annular supply pipeline 1 from the feeding hole 11, then the traction steel wires 5 pull the variable-diameter scraper mechanisms 4 to move along the annular supply pipeline 1 under the action of the buckling type driving traction mechanism 2 and the tensioning driven chain wheel mechanism 3, and the materials are pushed to the discharging hole 12; for the material with smaller diameter, the tension driven chain wheel mechanism 3 adjusts the tension force of the traction steel wire 5, so that the tension of the traction steel wire 5 is increased, at the moment, the traction steel wire 5 pulls the reducing slide shaft 43 to slide and extend out relative to the reducing guide cylinder 42, the reducing slide shaft 43 compresses the reducing return spring 44, and drives the fan-shaped slider units 452 to synchronously extend through the variable diameter connecting lugs and the transmission assemblies 451, because the adjacent fan-shaped slider units 452 are overlapped and attached to each other, each fan-shaped slider unit 452 still forms a closed circle after being extended, meanwhile, the clamping stagnation caused by the material embedded between two adjacent fan-shaped sliding block units 452 in the diameter changing process is prevented, thereby enlarging the movable radius of each fan-shaped slider unit 452, so that the clearance between each fan-shaped slider unit 452 and the pipe wall of the supply ring pipeline 1 is reduced, thereby adapting to the conveying work of materials with smaller diameter; and when the material with larger diameter needs to be conveyed, the tension of the traction steel wire 5 is reduced by tensioning the driven chain wheel mechanism 3, at the moment, the reducing sliding shaft 43 slides and retracts relative to the reducing guide cylinder 42 under the action of the reducing return spring 44, and each fan-shaped slider unit 452 is driven to retract inwards through each transmission assembly 451, so that the movable radius of each fan-shaped slider unit 452 is reduced, the gap between each fan-shaped slider unit 452 and the pipe wall is increased, the conveying work of the material with larger diameter is adapted, and the fan-shaped slider units 452 are prevented from being in friction contact with the pipe wall all the time.

The movable radius of each fan-shaped slider unit 452 is adjustable, so that the fan-shaped slider unit is suitable for materials with different diameters, the structure is flexible, the application range is wide, and energy consumption can be saved.

In the present embodiment, the feed inlet 11 and the discharge outlet 12 are preferably located on the same side of the annular feeding duct 1. Through the arrangement, two sides of the supply ring pipeline 1 are divided into a load side and an idle side, so that when the device works, the tension of the traction steel wire 5 part positioned on the load side is greater than that of the traction steel wire 5 part positioned on the idle side, and the movable radius of the fan-shaped slider unit 452 in the reducing scraper mechanism 4 positioned on the load side is greater than that of the fan-shaped slider unit 452 in the reducing scraper mechanism 4 positioned on the idle side, so that a better sealing and pushing effect can be obtained.
