Embodiment
As shown in the figure, the bracing frame of corn picker corn snapping unit of the present invention (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 installed on the snapping bar holder (7), driving gear (15) and sprocket wheel (16) are installed in snapping bar major axis (14) rear portion, be installed in 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), thus short snapping bar (13) and long snapping bar (23) while backward rotation.
Stock worm gear case assembly (11) and quarter butt worm gear case assembly (21) are connected on the set bolt (4) by attachment pegs (5), stock worm gear case assembly (11) mainly is to be made of worm gear case shell (101), worm gear (102), long worm screw (103), and quarter butt worm gear case assembly (21) mainly is to be made of worm gear case shell (101), worm gear (102), short worm screw (104).All stretch out outside the 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 the 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 the standing grain drive sprocket (3) rice-pulling chain (2) be housed, by the rice-pulling chain support wheel (9) on the 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.
There is crowded fringe bar (8) rear end of long snapping bar (23) and short snapping bar (13), squeeze fringe bar (8) projection on the surface of long snapping bar (23) and short snapping bar (13), the front end of long snapping bar (23) is welded with carries screw feeder (22).
The course of work is: at first corn combine travels forward, rice-pulling chain (2) simultaneously reverse drive with maize straw to short snapping bar (13) and long snapping bar (23) third side to conveying, when stalk is sent to short snapping bar (13) and long snapping bar (23) front portion, by short snapping bar (13) and anterior the leading fringe cone (12) and carry screw feeder (22) that stalk is continued to deliver to short snapping bar (13) and long snapping bar (23) rear portion of long snapping bar (23), crowded fringe bar (8) on short snapping bar (13) and long snapping bar (23) rear portion is backward rotation simultaneously, the corncob on the stalk is forced down finished ear harvesting operation.Because corn variety is different with maturity, cause the thickness of stalk different, can adjust the distance between short snapping bar (13) and the long snapping bar (23) by the set bolt (4) on the retractable support frame (1), finish the ear harvesting operation of different thicknesses stalk.
