The utility model belongs to and discloses a harvester which is characterized in that a chopping housing of the harvester is fixedly connected to a rack, and the chopping housing is provided with a chopping discharge port; the chopping assembly is arranged in the chopping housing and used for chopping materials. In the height direction of the harvester, a grass discharging opening of the threshing assembly is located between the top and the bottom of a chopping area of the chopping assembly. The grass skiing and chopping adjusting part is connected to the chopping housing and has a first working state and a second working state, an inlet is formed between the grass skiing and chopping adjusting part and the chopping housing in the first working state, the inlet is communicated with the grass discharging opening and the chopping discharging opening, and the grass skiing and chopping adjusting part is communicated with the chopping discharging opening in the second working state. A grass discharging channel communicated with the grass discharging opening is formed between the chopper and the screen box. The harvester is simple in structure, low in production cost and high in efficiency of chopping straws and directly discharging the straws without chopping, the risk that the chopped straws block the chopping discharge outlet in the process of discharging the chopped straws from the chopping discharge outlet can be effectively reduced, and the risk of blocking in the process of directly discharging the straws without chopping can be effectively reduced.

The invention relates to the field of silk yarns, in particular to a metallic yarn preparation process which comprises the following steps: S1, plating metal on a polyester film in vacuum, and then coating a transparent resin protective layer to obtain a basic raw material film; s2, the basic raw material thin film is wound into a roll, and the roll is installed on a shredding device; s3, the two ends of the basic raw material film roll are shredded at the same time through two cutters of a shredding device; and S4, winding and collecting the silk yarn at the same time to obtain the metallic yarn. The shredding device comprises a base transversely provided with a first transverse groove, two side supporting plates symmetrically sliding in the first transverse groove, two rotating bases rotationally connected to the upper ends of the two side supporting plates correspondingly, two conical heads fixed to the inner sides of the two rotating bases correspondingly, a two-way screw I transversely rotating in the first transverse groove, and a two-way screw II transversely rotating in the second transverse groove. The two side supporting plates are in threaded connection with the two ends of the two-way screw I respectively. According to the shredding device, shredding can be conducted through the two cutters at the same time, and the shredding efficiency is high.
