Technical field
The utility model relates to driving mechanism, the especially power between the power and workpiece and the driving mechanism between farming wheel and the road wheel on the microtilling machine.
Background technique
The microtilling machine of conventional known has only a pair of coaxial cultivated wheel usually, and power is delivered on the cultivated wheel with chaindriven the combination through shaft drive, chain-driven or shaft drive, and cultivated wheel had both been made the usefulness on cultivated land ground, bearing walking function again, therefore handle very difficult, poor stability, the efficient of manufacturing operation is low.In recent years, begin to have the microtilling machine that farming function and walking function are separated on the market, promptly microtilling machine is provided with farming wheel and road wheel, farming wheel and road wheel are driven through driving mechanism respectively by power, but because whole employings is shaft drive, there is complex structure, heaviness, the problem that assembling, maintenance difficult and cost are high.
The model utility content
Problem to be solved in the utility model provides a kind of simple in structure, adjustable driving mechanism of the double-stranded bar of assembling is easy to maintenance and cost is low microtilling machine.
For solving the problems of the technologies described above, the adjustable driving mechanism of the double-stranded bar of the microtilling machine that the utility model provides, have transmission case, walking case, input shaft, plough wheel shaft and live axle, the transmission case upper end links to each other with walking case leading flank top and forms the man type housing structure, the inner chamber of transmission case and walking case communicates, plough wheel shaft by the bottom of Bearing Installation at transmission case, live axle by Bearing Installation at the walking lower box part; On the transmission shaft of walking in the case two sprocket wheels are housed, these two sprocket wheels link to each other with sprocket wheel on cultivated wheel shaft, the live axle by chain respectively, input shaft and be equipped with between the transmission shaft of sprocket wheel and be provided with the gear graduation driving mechanism.
Because transmission case and walking case are connected to the man type housing structure, the farming transmission system of microtilling machine and walking transmission system are except that shared input shaft, also shared set of gears variable transmission mechanism, power is ploughed on wheel and the road wheel through being delivered to respectively by two chains after the speed change again, thus the separating of realization farming and walking function.Adopt chain-driven, not only make simple in structurely, and can alleviate the weight of whole box body, reduce manufacture cost.The chain-driven mode also has easy to assembly, and maintenance is easy to characteristics.
Above-mentioned transmission case and walking case are the integrated structures that is welded through punching press with steel plate, the walking case open-topped and by cover plate for sealing, two madial walls are provided with the vertical groove of symmetry about the walking case, input shaft, transmission shaft and gear graduation driving mechanism are installed on the quadra made from steel plate, and the quadra that above-mentioned axle, gear and sprocket wheel are housed is done as a whole putting into and spacing vertical groove at the walking upper box part on the walking case.Adopt this structure both to overcome that traditional full punching structure casing intensity is low, the problem of sealing difference, overcome traditional full cast moulding casing heaviness, defect of high cost again, mounting or dismounting more convenient operation, quick.
The top of said frame and trailing flank all are connected with the adjusting bolt, and adjusting bolt one end of frame roof stretches out in cover plate and is with adjusting nut thereon, and adjusting bolt one end of framework trailing flank stretches out in walking case rear sidewall and is with adjusting nut thereon.During the turn adjusting nut, change the distance of sprocket wheel between transmission shaft and cultivated wheel shaft or the live axle by pulling or promotion framework, thereby reach the purpose of regulating the chain degree of tightness.
Above-mentioned live axle by about two semiaxis form, match for cylindrical or spherical convex-concave between two semiaxis, the sprocket wheel kink is on the smooth section of two-semiaxle junction, all can be set with clutch gear axially slidably by spline on two semiaxis, two clutch gears are resisted against on the sprocket wheel from the left and right sides under the effect of pressure spring respectively.Adopt the cylindrical or spherical convex-concave structure that matches, make between two semiaxis and interconnect support, rotational restraint each other not again, when one of them clutch gear is mobile laterally under shift fork drives, double wedge on the clutch gear separates with groove on the sprocket wheel, power on the sprocket wheel can not be delivered on the semiaxis at this clutch gear place, has only a road wheel this moment in running, thereby can realize turning to.
The beneficial effects of the utility model are: simple in structure, in light weight, sealing is reliable, assembles easy to maintenance and low cost of manufacture, makes the manipulation of microtilling machine easier.
