Two ends of the screw shafts 130 are mounted by using bearing seats 131, one ends of the two screw shafts are connected with a power output shaft in the reducer 122 through chain transmission of a chain wheel and a chain, and the two screw shafts 130 synchronously rotate in the same direction. The other ends of the two spiral shafts are provided with a discharge barrel 113 and a discharge port 114, wherein the discharge barrel 113 is a section extending from the feed bin. The two screw axes 130 are of different lengths, i.e., one screw axis is long and the other screw axis is short. The discharge ports 114 of the two spiral shafts are positioned at different length positions of the discharge barrel, namely, are arranged in a staggered manner. One or two belt conveyors 200 are arranged below the two discharge ports 114, and materials output by the spiral shaft are continuously conveyed out through the belt conveyors, so that the next process can be carried out for crushing. Referring to fig. 4 to 7, in the conveying line, the belt conveyor and the quantitative tail vegetable feeder are used in various combinations, for example, in fig. 4, only one belt conveyor 200 is arranged below two discharge ports 114, and projections of the two discharge ports 114 in the same vertical plane do not intersect, and the tail vegetables on the belt conveyor 200 are uniformly distributed due to the same rotating speed of the two screw shafts 130. In fig. 5, two belt conveyors convey the tail vegetables quantitatively and directionally in opposite directions. In fig. 6, two belt conveyors convey the tail vegetables quantitatively in directions perpendicular to each other. In fig. 7, two belt conveyors convey the tail vegetables quantitatively and directionally in the same direction. Therefore, in this embodiment, the conveyor line has the characteristic of flexible arrangement.

That is, in this embodiment, the screw shafts 130 have different lengths, so that the material output from the screw shafts 114 is different, and the material output from the screw shafts can be distributed on the belt conveyor below, thereby avoiding the situation of material accumulation or uneven distribution.

The motor is fixed on the frame at the lower part of the storage bin, and the motor shaft is respectively in power transmission with the chain wheels on the two screw shafts above through the speed reducer and the two sets of chain wheel and chain transmission mechanisms.

Furthermore, the heights of the two inclined plates on the left side and the right side of the w-shaped bottom plate of the bin are different to form a certain height difference, so that the forklift can pour the tail vegetables into the bin conveniently, and specifically, the height of the inclined plate at the end, where the tail vegetables are rolled out from the spiral shaft, of the right end of the bin is lower than that of the inclined plate at the end, where the tail vegetables are rolled into one end from the spiral shaft, of the left end of the bin, so that the tail vegetables.

In this embodiment, the above-mentioned driving motor is a servo motor, and the rotation speed is adjustable, i.e. the higher the speed is, the faster the material is discharged, and the lower the rotation speed is, the slower the material is discharged, and is used for matching with equipment (such as a pulverizer) with different production capacities.

Furthermore, the belt conveyor also uses a servo motor with adjustable speed, and the speed can be adjusted and controlled according to the application occasions.

Furthermore, the two screw shafts in the embodiment rotate in the same direction, are in a space and are driven by the same motor, and the structure is simple, reliable and efficient.
