Description
Technical field
The utility model relates to a kind of farm machinery, particularly the left and right clutch transfer on the multifunction windrower.
Background technology
At present, along with being extensive use of of agricultural machinery such as cultivator, sower, transplanter, grain header, improved the mechanization level of China's agricultural production greatly.Swather is the special machine of crops such as harvester for rice wheat, in the mountain area, the hilly country is widely used.The output shaft of existing swather is generally an axis, on this axis road wheel is installed.Because the power of engine passes to output gear on the output shaft by the gear drive in the transmission case, load on the output shaft is big, when turning to, swather need very big power just can reverse road wheel, the one side operation is required great effort, labour intensity is big, on the other hand, the reliability of steering operation is relatively poor, and falls down easily because of operating personnel overexert when turning to, and has serious potential safety hazard.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of left and right clutch transfer of multifunction windrower of rapid operation.
The technical solution of the utility model is as follows: the left and right clutch transfer of a kind of multifunction windrower, bottom in casing is provided with output gear, its key is: described output gear is set in the middle part of alignment pin, in the both sides of output gear a semiaxis is set respectively, described semiaxis is bearing on the casing by bearing, oppositely stretch out outside the casing outer end of two semiaxis, and the inner of each semiaxis is sleeved on the alignment pin, and the inner of semiaxis is connected with output gear by clutch; All be connected with the shift fork combination on the clutch of described output gear both sides, each shift fork combination is connected with the lower end of pull bar, and the upper end of pull bar is connected with the inner of steering spindle, and stretch out outside the casing outer end of described steering spindle, and extension suit steering crank.
The utility model replaces with two semiaxis with the output shaft in the traditional structure by an axis, and semiaxis is connected with output gear by clutch.Turn to crank to be connected with handle by drag-line in the utility model, handle is arranged on the below of armrest handle.Clutch is in normal engagement, and the power that is delivered to output gear like this can pass to two semiaxis smoothly by the clutch of both sides, rotates forward with ground-engaging wheel.When needs turn to the left or to the right, grasp the handle on the left side or the right, handle is turned an angle by the drag-line drive steering crank of correspondence, when steering crank rotates, upwards spur pull bar, make pull bar stir clutch separation by the shift fork combination, power between the output gear and the left side or the right semiaxis is cut off like this, load reduces greatly on this semiaxis, and reverse handrail towards the direction of this limit semiaxis this moment, can realize very like a cork turning to.
Above-mentioned clutch is made up of outer cover, spring and steel ball, wherein the outer cover kink is on semiaxis, the annular boss at output gear end face middle part is stretched in the inner of semiaxis, on annular boss, have a circle by the equally distributed locating hole of circumference, be embedded steel ball in each locating hole, this steel ball is pressed between outer cover and the semiaxis, and the position of the close steel ball of outer cover inwall has a circle slot to make way; Described spring is installed in the outer cover, step surface butt, the other end of spring and the step surface butt on the semiaxis in an end of spring and the outer cover.In the above structure, output gear by steel ball to the semiaxis transferring power, when the shift fork combination is stirred outer cover when the direction of output gear is moved, slot to make way on the outer cover inwall moves to the position over against steel ball, outer cover unclamps the compressing to steel ball like this, steel ball skids, and the power between output gear and the semiaxis is cut off; The shift fork compound action is after the power on the outer cover disappears, and under the effect of spring, outer cover resets fast.This shows that clutch can be realized separating fast and engaging, and is not only simple in structure, easy to assembly, and running flexibly, good reliability.
The position corresponding with steel ball has a circle by the equally distributed shallow slot of circumference on the above-mentioned semiaxis, helps so on the one hand the steel ball location, and on the other hand, in transferring power, the contact area of steel ball and semiaxis is big, can keep the stationarity of transmission of power.
Above-mentioned shift fork combination is made up of shift fork, declutch shift shaft and pressing plate, and wherein the middle part of declutch shift shaft is connected with the lower end of pressing plate, and the upper end of pressing plate is fixed on the casing by screw; Described shift fork is " L " shape structure, and the flex point at this shift fork middle part and the end of declutch shift shaft are fixed, and the lower cantalever end of shift fork is connected with outer cover, and the upper cantilever end of one of them shift fork and the lower end of pull bar are hinged.More than simple and reliable for structure, easy accessibility, it is smooth and easy to guarantee that outer cover moves along semiaxis.
For parts such as drag-line, steering spindle, pull bar are resetted fast, above-mentioned steering crank by nut check on steering spindle, and near the small boss on the cabinet exterior, suit torsion spring on this small boss, one of them leg of this torsion spring rides on the casing, another leg of torsion spring and steering crank overlap joint.
Beneficial effect: the utility model can be realized turning in flexibility and reliability ground by the load that reduces on the semiaxis, simultaneously rapid operation, safety.
