Utility model content
The purpose of this utility model is to provide a kind of Multifunctional micro-ploughing that mini-tiller can be made to have a variety of tillage system reforms
Machine transmission mechanism.
To reach above-mentioned purpose, base case of the present utility model is as follows：
Multifunctional small tiller transmission mechanism includes housing, and the clutch, walking transmission mechanism and operation in housing are passed
Motivation structure, the walking transmission mechanism and operation transmission mechanism are connected by engaging sleeve one, and the walking mechanism includes and housing
Rotate the first power transmission shaft, second driving shaft, reversing shaft and the walking output shaft of connection, first power transmission shaft, second driving shaft
It is be arranged in parallel with reversing shaft, the walking output shaft is vertical with second driving shaft, the clutch is by engine output shaft and the
One power transmission shaft one end is connected；The operation transmission mechanism includes commutation portion, gear shift portion and reduction part；
The first power transmission shaft other end is fixedly connected with one grade of driving gear and two grades of driving gears, second transmission
Being rotatably connected to that key on the first speed driven gear engaged all the time with one grade of driving gear, second driving shaft is connected with axle can be
It is fixed with two grades of driven gears on the sliding sleeve slided on two power transmission shafts, sliding sleeve, the opposite end of sliding sleeve and first speed driven gear is provided with
Mutually engageable engaging tooth；Output gear one and reverse driving gear, output gear one and one are fixed with the reversing shaft
Shelves driving gear or two grades of driving gears are engaged, and two grades of driven gears can be engaged with reverse driving gear；
The commutation portion includes the power input shaft and power transmission shaft for being mutually perpendicular to and being connected with housing into rotation, and power is defeated
Enter axle one end to be connected with engaging sleeve one, the power input shaft other end is fixed with input bevel gear, the two ends of the power transmission shaft

The principle of this programme multifunctional small tiller transmission mechanism is：
The output shaft of engine is connected by the clutch of the multifunctional small tiller transmission mechanism with the first power transmission shaft, works as clutch
Device is combined, and engine will drive the first drive axis.When sliding sleeve is engaged with first speed driven gear, two grades of driven gears and two grades
Driving gear is disengaged from, then first speed driven gear will drive second driving shaft to rotate by sliding sleeve, then output shaft of walking is with one
Shelves output；When sliding sleeve is disengaged from first speed driven gear, two grades of driven gears are engaged with two grades of driving gears, then two grades it is driven
Gear will drive second driving shaft to rotate by sliding sleeve, then output shaft of walking is with two grades of outputs；When sliding sleeve and first speed driven gear
It is disengaged from, two grades of driven gears are disengaged from two grades of driving gears, then output shaft of walking is in neutral state；As reverse gear master
Moving gear is engaged with reverse gear driven gear, then reverse gear driven gear drives second driving shaft to rotate by sliding sleeve, then walking output
Axle is exported with reverse gear.From the foregoing, walking transmission mechanism has four gears, respectively one grade, two grades, neutral gear and reverse gear；
One grade and two grades be drive shift, i.e. mini-tiller using one grade or two grades work when, along the direction of travel of mini-tiller, walking mechanism exists
The front of Working mechanism；When mini-tiller is worked using reverse gear, along the direction of travel of mini-tiller, walking mechanism is after Working mechanism
Side, and operating personnel are typically located at Working mechanism side, a therefore reverse gear more at a slow speed is only set, it is micro- when can prevent backward
The machine of ploughing walking is too fast, the cutter injury operating personnel in Working mechanism.
Operation transmission mechanism can realize main story and the reversion of Working mechanism cutter, make operation more flexible.Operation transmission mechanism
When the power input shaft in commutation portion is rotated, input bevel gear will drive Intermediate bevel gears to rotate, because Intermediate bevel gears distinguish position
In the both sides of input bevel gear, therefore the steering of two Intermediate bevel gears is opposite；Engaging sleeve two is stirred by shift fork, makes engaging sleeve two
Combined from different Intermediate bevel gears, then the steering that can change the steering of engaging sleeve two, i.e. power transmission shaft changes, so that subtracting
The steering of fast portion's deceleration output gear changes.The power of Working mechanism is exported by reduction part, and the power of reduction part is through commutation
