Abstract
Claims
1. A screw conveyor for a soybean harvester, comprising a roller (103) disposed between two side wall plates (1), characterized in that: The two side wall panels (1) are slidably mounted with slide blocks (102) on their opposite surfaces via slide rails (101), and the two ends of the roller (103) are rotatably connected to the two slide blocks (102) respectively. Two helical blades (104) are symmetrically arranged on the outer surface of the roller (103). A telescopic tooth (110) is provided in the middle of the outer surface of the roller (103). A screw (105) with a pair of reverse threads is rotatably installed inside the roller (103). A helical pair (106) is installed on both of the reverse threads of the screw (105). A support plate (107) is hinged to the outer surface of the helical pair (106). A first through groove (108) is provided at the middle position of the surface of the roller (103), and an arc plate (109) is provided inside the first through groove (108). The ends of the two support plates (107) are hinged to the arc plate (109).
2. The screw conveyor for a soybean harvester according to claim 1, characterized in that: The top wall of the roller (103) is provided with a groove (2), and a slide rod (201) is installed on the outer surface of the helical pair (106).
