Embodiment:

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4,12 among the figure is arch (bridge) type frames, is fixed with 18 4 wheels of front-wheel 11 and trailing wheel below arch (bridge) type frame 12, and two wheels 11 of front are deflecting roller, and two wheels 18 of back are driving wheel.Trailing wheel 18 is installed in the both sides, rear portion of frame 12 by the semiaxis housing, in the semiaxis housing jack shaft is housed, and by jack shaft mechanical transmissions 24 is transmitted the transmission of power of coming and gives trailing wheel 18.Two front-wheel wheels 11 all are connected with connecting plate 9 by two shock absorbers 10, connecting plate 9 adopts key connecting with the lower end of knuckle vertical shaft 8, knuckle vertical shaft 8 by two bearings up and down in the knuckle vertical shaft sleeve of frame 12 front part sides, knuckle vertical shaft 8 upper ends are connected with the lower end of knuckle power transmission shaft 4 by shaft coupling (following steering arm) 6, bearing is passed through on the top of knuckle power transmission shaft 4, bearing block is fixed on the frame 12, the upper end of knuckle power transmission shaft 4 and steering arm 2 adopt key joint, the steering arm 2 of left and right sides is hinged by drag link 1, forms the overhead system steering.5 biasings of direction machine are fixed on a side of arch (bridge) type frame 12, the pitman arm 14 of direction machine 5 is hinged by longitudinal tie 7 with following steering arm 6, when rotation direction machine 5, the power of direction machine 5 outputs is realized turning to through pitman arm 14, longitudinal tie 7, two deflecting roller deflections in the same way of steering arm 6 drivings down.Engine 16, basic transmission 21, auxiliary transmission 17 and other parts all are fixed on the bottom of a side of arch (bridge) type frame 12, the power of engine 16 passes to auxiliary transmission 17 by V-type band 19, clutch 29, by auxiliary transmission 17 speed changes become turn round after, give basic transmission 21 by mechanical transmissions 22 with transmission of power, after the change of basic transmission 21 speed changes is turned round, power is exported from two semiaxis respectively by differential mechanism.Power on one of them semiaxis is directly passed to the trailing wheel 18 of speed changer place side through mechanical transmissions 24, and the power of another semiaxis output is delivered to the trailing wheel 18 of opposite side again through mechanical transmissions 24, behind the gap bridge axle 30 on frame 12 tops.The engine front is equipped with the driver and takes with seat 28, hydraulic oil pump 15 is installed below the seat 28; The hydraulic jack 27 that promotes farm implements is installed in the top of frame 12, lift shaft 33, interior lift arm 25, outer lift arm 26 etc. all are installed in frame 12 by lift shaft bearing 32 top; Lift shaft 33, outer lift arm 26 are driven by same hydraulic jack 27, and lift shaft 33 is hinged with connecting rod 31 by interior lift arm 25, forms double rocker mechanism, realizes that 4 of farm implements articulate or trifilar suspension.A part of power of engine drives hydraulic oil pump 15 by the V-type band and produces hydraulic oil, behind reversal valve, enter farm machinery and promote hydraulic jack 27, the power of hydraulic jack 27 outputs drives former and later two lift shaft 33 swings respectively through interior lift arm 25, connecting rod 31, four outer lift arm 26 swings before and after lift shaft 33 drives, outer lift arm 26 makes the farm machinery lifting by raising rod, hoisting mechanism both can with the farm implements trifilar suspension, also can with the facility four-point suspension.Power output wheel 20 is housed on the power input shaft of basic transmission 21, and the power of power output wheel 20 outputs can drive the farm machinery that need the power input, the needs of finishing traction and driving.

When the present invention carried out farm work, at first ato unit 16, depress clutch pedal, hung up suitable gear, release the clutch pedal, and the power of engine 16 rotates by the transmission system drives trailing wheel, and the traction farm implements advance.When needs turn to, driver's steering wheel rotation, the power of pitman arm 14 outputs of direction machine 5 is realized two front-wheel 11 deflections in the same way by parts such as longitudinal tie 7, following steering arms 6, form steering moment for the reaction force of front-wheel 11 by ground, make differential mechanism produce differential, interior side drive wheel 18 slow-speeds, outer side drive wheel 18 is changeed soon, realizes smoothly turning to.When needs promote farm implements, the driver's operation reversing handle, change-over valve core is slided, the high-pressure and hydraulic oil that control hydraulic oil pump 15 produces flows to single-acting hydraulic jack 27, hydraulic oil promotes hydraulic piston, piston rod moves, the power of piston rod output is through interior lift arm 25, connecting rod 31, lift shaft 33, and outer lift arm 26 is put on lift shaft 33 synchronously before and after making, and by raising rod farm implements is promoted; In the time of need putting down farm implements, the operation reversing handle slides change-over valve core, reversal valve makes the hydraulic oil in the single-acting hydraulic jack 27 communicate with hydraulic oil container, hydraulic oil in the hydraulic jack 27 flows back to hydraulic oil container under the effect of farm implements gravity, the outer lift arm 26 in front and back realizes that by raising rod farm implements descend synchronously around lift shaft 33 bottoms.

Compare with existing tractor, tiller, the present invention has adopted arch (bridge) type frame, overhead system steering, engine, transmission system offset placement, its outstanding advantage is the high and low center of gravity in crack, ground, the walking device lateral dimension is little, in light weight, trafficability characteristic is good, satisfy the needs of farm work in the whole growth cycle of high bar crops, utilization rate height, operating maintenance are easy.

Adopt arch (bridge) type frame, overhead system steering that the crack, ground of working rig is increased substantially; Adopt engine, auxiliary transmission, basic transmission offset placement in the bottom of a side of arch (bridge) type frame, reduced the center of gravity of machine, reduced the width of running gear, improved and passed through performance.
