Embodiment
As shown in the figure, the bracing frame of corn picker corn snapping unit of the present utility model (1) is the seam structure, and front opening is splayed and outwards separates, and provides support for the installation of other parts.Snapping bar holder (7) is fixed on bracing frame (1) rear portion, and set bolt (4) is fixed on bracing frame (1) middle part, and rice-pulling chain support wheel (9) is fixed on bracing frame (1) front end.
snapping bar major axis (14) and snapping bar minor axis (24) are arranged on snapping bar holder (7), driving gear (15) and sprocket wheel (16) are arranged on snapping bar major axis (14) rear portion, be arranged on snapping bar minor axis (24) rear portion with the driven gear (25) of driving gear (15) engagement, when sprocket wheel (16) driven and when rotating, sprocket wheel (16) drives driving gear (15) by snapping bar major axis (14) and rotates, driving gear (15) drives driven gear (25) and snapping bar minor axis (24) rotates, the front portion of snapping bar major axis (14) and snapping bar minor axis (24) is fixed together by steady pin (6) and short snapping bar (13) and long snapping bar (23), short snapping bar (13) and long snapping bar (23) backward rotation simultaneously thus.
Stock worm gear case assembly (11) and quarter butt worm gear case assembly (21) are connected on set bolt (4) by attachment pegs (5), stock worm gear case assembly (11) is mainly to be made of worm gear case shell (101), worm gear (102), long worm screw (103), and quarter butt worm gear case assembly (21) is mainly to be made of worm gear case shell (101), worm gear (102), short worm screw (104).All stretch out outside worm gear case shell (101) at the two ends of the long worm screw (103) of stock worm gear case assembly (11), and wherein an end inserts the front end of short snapping bar (13), and the other end is equipped with leads fringe cone (12); The short worm screw (104) of quarter butt worm gear case assembly (21) only has an end to stretch out outside worm gear case shell (101), inserts the front end of long snapping bar (23).The top of stock worm gear case assembly (11) and quarter butt worm gear case assembly (21) all is equipped with group standing grain drive sprocket (3) coaxial with worm gear (102), dial on standing grain drive sprocket (3) rice-pulling chain (2) be housed, by the rice-pulling chain support wheel (9) on bracing frame (1) with rice-pulling chain (2) stretching.Short snapping bar (13) and long snapping bar (23) rotate respectively the worm gear case assembly input power to separately simultaneously, drive to dial standing grain drive sprocket (3) and rotate, thereby drive rice-pulling chain (2) transmission.
