Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of tensioning clutch that is used on the grain header, it includes and is arranged on the drive pulley on the output shaft 1 on the engine, be arranged on first driven pulley 2 on the grain header running gear, be arranged on second driven pulley 3 on the grain header transmission mechanism, first contact roller 4 and second contact roller 5, drive pulley 1 is connected with first driven pulley 2 by first driving belt 6, drive pulley 1 is connected with second driven pulley 3 by second driving belt 7, first contact roller 4 and second contact roller 5 are separately positioned on an end of first cursor 8 and second cursor 9, the other end of first cursor 8 and second cursor 9 is hinged on the grain header frame, on first cursor 8 and second cursor 9, be provided with a spring 10, the other end of spring 10 is connected with a drag-line 11 respectively, first contact roller 4 is corresponding with first driving belt 6, and second contact roller 5 is corresponding with second driving belt 7.
During work, ato unit, when grain header need be walked, pulling drag-line 11, drag-line 11 drives first cursor 8 by spring 10 and presses down, first cursor 8 drives first contact roller 4 and presses down, first driving belt 6 is pressed on the drive pulley 1 and first driven pulley 2, strengthen the frictional force between first driving belt 6 and drive pulley 1 and first driven pulley 2, drive pulley 1 drives first driven pulley 2 by first driving belt 6 and rotates, first driving pulley 2 drives the grain header walking, otherwise, unclamp drag-line, the frictional force that first driving belt 6 acts on the drive pulley 1 and first driven pulley 2 is not enough to drive 2 rotations of first driven pulley, drive pulley 1 idle running; When grain header need gather in threshing, pulling drag-line 11, drag-line 11 drives second cursor 9 by spring 12 and presses down, second cursor 9 drives second contact roller 5 and presses down, second driving belt 7 is pressed on the drive pulley 1 and second driven pulley 3, strengthen the frictional force between second driving belt 7 and drive pulley 1 and second driven pulley 3, drive pulley 1 drives second driven pulley 3 by second driving belt 7 and rotates, second driving pulley 3 drives transmission mechanism starts working header and threshing tube, otherwise unclamp drag-line 11, the frictional force that second driving belt 7 acts on the drive pulley 1 and second driven pulley 13 is not enough to drive 3 rotations of second driven pulley, drive pulley 1 idle running.
Also be provided with depression bar 12 on the grain header frame, depression bar 12 positions are corresponding with first driving belt 6 and second driving belt 7.If there is not depression bar 12, when unclamping drag-line 11, first driving belt 6 and second driving belt 7 can automatically reset, up and down the expansion, cause two ends, the left and right sides to shorten, strengthened and drive pulley 1, first driven pulley 2 and second driven pulley 3 between frictional force, the idle running effect is undesirable, after adding depression bar 12, can prevent first driving belt 6 and 7 expansions of second driving belt, make drive pulley 1 idle running better effects if.
