Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1, Fig. 2, a kind of mini-size tillage machine steering, comprises walking case, and described walking case comprises walking case upper box 11, walking case lower box, longitudinal drive shaft 2 and two output axle shafts 3.Described longitudinal drive shaft 2 is located in walking case upper box 11, and its upper end is provided with an input bevel gear, and lower end is provided with an input bevel gear 4.During concrete enforcement, described walking case lower box comprises left shell 121 and the symmetrical both sides being located at lower box of right shell body 122, two output axle shaft 3, and corresponding the stretching into from left shell 121 and right shell body 122 in its one end is walked in case lower box.Two output axle shafts 3 are connected with walking case lower box respectively by a deep groove ball bearing; Thus make the operation of output axle shaft 3 more stable.
A horizontal power transmission shaft 5 is provided with in walking case lower box, the axial line of this horizontal power transmission shaft 5 overlaps with the axial line of two output axle shafts 3, power transmission shaft is arranged with a drive bevel gear 6, and described drive bevel gear 6 engages with the input bevel gear 4 of longitudinal turning cylinder lower end.The two ends of described horizontal power transmission shaft 5 axle body are connected with two output axle shafts 3 respectively by a separator disk 7, described separator disk 7 is sheathed on horizontal power transmission shaft 5 and output axle shaft 3 simultaneously, wherein, this separator disk 7 is fixedly connected with horizontal power transmission shaft 5, is rotationally connected with output axle shaft 3.The one end stretching into walking case lower box at two output axle shafts 3 is all axially arranged with a groove along it, and the spindle nose at described horizontal power transmission shaft 5 two ends inserts in the groove of two output axle shafts 3 respectively, and can freely rotate; Thus the stability that two output axle shafts 3 run can be ensured better.The part overlapped with output axle shaft 3 at separator disk 7 is provided with several ball in 7 one weeks around separator disk, and on output axle shaft 3, the position of corresponding each ball is equipped with deep-slotted chip breaker, is respectively equipped with a steel ball 8 in each ball.
The one end stretching into walking case lower box at output axle shaft 3 turns to driver plate 9 to be connected with separator disk 7 by one, described in turn to one end of driver plate 9 to be set on output axle shaft 3, the other end is set in and turns on driver plate 9, and can move along its axis.Be provided with one inside driver plate 9 and turn to clutch stage clip 10 turning to, described in turn to clutch stage clip 10 to be set on output axle shaft 3, its one end is connected with turning to driver plate 9, and the other end is connected with separator disk 7.When turning to clutch stage clip 10 to be in extended configuration, described in turn to driver plate 9 to act on steel ball 8, and steel ball 8 is pressed in the deep-slotted chip breaker on output axle shaft 3; Also be provided with a cannelure 101 turning to inside driver plate 9, move when turning to driver plate 9 and compress when turning to clutch stage clip 10, steel ball 8 can partly enter in this cannelure 101.
In walking case lower box, be also provided with two turn to shift fork 102, the described shift fork 102 that turns to is turning between driver plate 9 and walking case lower box, and be rotationally connected by rotating shaft and walking case lower box, turn to shift fork 102 to be connected with one end of clutch bracing wire 103, the other end of clutch bracing wire 103 stretches out from walking case lower box simultaneously; Pulling clutch bracing wire 103, can driving along turning to moving axially of driver plate 9, and drive turns to driver plate 9 to turn to the direction of clutch stage clip 10 to move towards compression.The left shell 121 and right shell body 122 of walking case lower box have a bracing wire hole, and described clutch bracing wire 103 is stretched out from this bracing wire hole.
In the course of work, when needs are turned, only need to pull side clutch bracing wire 103, thus this side clutch bracing wire 103 is driven along turning to moving axially of driver plate 9, and drive turns to driver plate 9 to turn to the direction of clutch stage clip 10 to move towards compression; When turning to the cannelure 101 of driver plate 9 and steel ball 8 just pair, steel ball 8 to move and part enters in cannelure 101, thus steel ball 8 departs from the deep-slotted chip breaker of output axle shaft 3, makes horizontal power transmission shaft 5 no longer drive output axle shaft 3 to rotate; But the output axle shaft 3 due to opposite side still keeps rotating, thus makes mini-size tillage machine turn to.Only clutch bracing wire 103 need be pulled in whole operating process, easy to operate, quick, and turning efficiency is good.
After having turned to, only need unclamp clutch bracing wire 103, turn to driver plate 9 to get back to original position under the effect turning to clutch stage clip 10, and again steel ball 8 is pressed in the deep-slotted chip breaker of output axle shaft 3, thus normally walk.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
