Among the figure, 1 is tractor, and 2 are the tractor dynamic power wheel, and 3 is belt, and 4 is pull bar, 5 is driving lever, and 6 is link, and 7 is handle, and 8 is bearing block, 9 is block set, and 10 is castle wheel, and 11 is drive A, and 12 is hitch frame, 13 is clutch shaft, and 14 is spring, and 15 is clutch-plate, and 16 is belt, 17 is drive B, and 18 is field-returning machine, and 19 is cross bar, and 20 is vertical pole, 21 is lower connecting plate, and 22 is brace, and 23 is upper junction plate, and 24 is fixed pulley.
Embodiment:
Below in conjunction with embodiment, the utility model is done further narration.
Embodiment 1: as shown in Figure 1 and Figure 2, the power wheel 2 of tractor 1 connects castle wheel 10 by belt 3, castle wheel 10 is fixed in an end of clutch shaft 13 by the bearing activity, be combined with clutch-plate 15 with castle wheel 10, clutch-plate 15 inboards are provided with spring 14, and spring 14 withstands clutch-plate 15 laterally, make convex and concave teeth on the clutch-plate 15 and the convex and concave teeth interlock on the castle wheel, be provided with driving lever 5 in the outside of clutch-plate 15, driving lever 5 is controlled by pull bar 4, and the other end of pull bar 4 is connected with handle 7; Operating grip 7 forms and to push away or when drawing pull bar 4, clutch-plate 15 is stirred or decontroled to driving lever 5, thus cause clutch shaft 13 not with or follow castle wheel 10 and rotate; Clutch-plate 15 striking gears can also be following structures: driving lever 5 is by driving lever lever control clutch-plate 15, movable fixing in the middle of the driving lever lever by axle, one end cylinder lever connecting rod (or backguy) of driving lever lever, the other end is used to control driving lever 5, and the other end of pull bar 4 is connected with handle 7; At this moment, operating grip 7 makes pull bar 4 pulling driving lever levers, and the driving lever lever is stirred driving lever 5, and driving lever 5 is stirred clutch-plate 15 and broken away from castle wheel 10, thereby clutch shaft 13 is not rotated with castle wheel 10.The other end of clutch shaft 13 is fixed with drive A11, drive A11 drives drive B17 by belt 16, field-returning machine 18 front portions are provided with hitch frame 12, the leading section of hitch frame 12 is provided with bearing block 8, be placed with bearing in the bearing block, one side of bearing block is provided with a horizontal short pipe, penetrate clutch shaft 13 in this weak point pipe, the internal diameter of short pipe is slightly larger than the diameter of clutch shaft, short pipe is outer can be inserted in and around its rotation, the internal diameter of block set 9 is slightly larger than the external diameter of short pipe for block set 9, and block set 9 can be around short pipe rotation, block set 9 is fixed on the link 6, and link 6 front portions are connected on the tractor 1.
The structure of link also can be set to as shown in Figure 3, two cross bars, 19 rear ends connect two vertical poles 20 respectively, cross bar 19 is connected by brace 22 with vertical pole 20, vertical pole 20 bottoms, middle part, top connect by connecting rod respectively, thereby form " day " font, " day " font frame upper back (vertical pole back) is fixed with sleeve pipe 9.Be fixed with lower connecting plate 21 in the bottom of brace 22, be connected with tractor by two connecting rods; (or top of brace) fixing upper junction plate 23 on the vertical pole of jib head connects tractor by screw mandrel, regulates screw mandrel, also the tensioning degree of adjustable straps 3; Be provided with fixed pulley 24 in the upper end of vertical pole 20, be installed with stay cord on the fixed pulley 24, be used for the lifting field-returning machine.This machine can also adopt hydraulic lifting.
Under normal circumstances, under the effect of spring 14, clutch-plate 15 and castle wheel 10 near, thereby castle wheel 10 can drive the rotation of clutch shaft 13, thereby drive the work of drive A, B; When needs turned round or travel, operating grip 7 can make clutch-plate 15 separate with castle wheel 10, and at this moment, castle wheel 10 still rotates under the drive of tractor dynamic power wheel 2, but can not drive the rotation of clutch shaft 13, and rise field-returning machine and get final product this moment.Because tractor dynamic power wheel 2 and castle wheel 10, the distance between drive A and drive B all can not change when lifting, thereby the phenomenon that belt degree of tightness inequality can not occur takes place.
