Embodiment

By Fig. 1 to Fig. 7 as can be known, it comprises hull 19, be installed in hull 19 the rear end gearbox 11 and be sleeved on the roller 32 that axle is produced in gearbox 11 both sides, when farming, power set rotate by gearbox 11 driving rolls 32, advance or fall back thereby make volume mud farming limit, roller 32 limits drive hull 19.Frame 21 is hinged with hull 19 by the frame rotating shaft 14 that is packed in hull 19 rear portions, the lower end of frame suspension rod 4 and frame 21 anterior hinged, frame suspension rod 4 upper ends and frame arm 5 front ends are hinged, frame arm 5 other ends by rotating shaft or directly and frame lift control lever 7 affixed.Be sleeved on barrel 36 closed at both ends of the roller 32 that installs on the left and right output shaft in gearbox 11 both sides, clean so that barrel 36 increases buoyancy and is convenient to.When needs are deep ploughed, by the anterior pull-up of frame lift control lever 7, and the roller 32 that is installed in frame 21 rear portions is sunk, thereby the degree of depth of farming is deepened frame 21.

The clutch operating lever 9 that is hinged on the hull 19 joins by clutch linkage 15 clutch with the clutch gear shaft 41 of gearbox 11, thus solenoidoperated cluthes deciliter.In gearbox, be sleeved on the clutch gear shaft 41 driven wheel be sleeved on back gear on the back gear axle 46 or the drive shift gears engaged on the drive shift gear shaft 42, back gear or drive shift gear and the travelling gear engagement that is sleeved on the tooth sector axle 43, under normal circumstances travelling gear respectively with left steering gear that is sleeved on both sides and right turn gears engaged, be sleeved on the left driven wheel engagement Left Drive gear driving gearshaft 44 on and left output shaft 39 on of left steering gear by being engaged with, the right turn gear meshes with right driven wheel on the right output shaft by the right travelling gear that is sleeved on the driving gearshaft 44 that is engaged with.

When the needs gear shift falls back or advances, control axle sleeve and join because of being hinged on the gear of gear operating lever 24 by gear connecting rod 28 and gear shift fork and gearbox 11 on the hull 19, therefore, can the gear Control Shaft be enclosed within on the clutch gear shaft 41 of gearbox 11 slide by handling gear operating lever 24 control gear shift forks, make the driven wheel that is sleeved on the clutch gear shaft 41 and be sleeved on back gear on the back gear axle 46 or certain the drive shift gears engaged on the drive shift gear shaft 42, and by back gear or certain drive shift gear and the travelling gear engagement that is sleeved on the tooth sector axle 43, because of travelling gear under normal circumstances respectively with left steering gear that is sleeved on both sides and right turn gears engaged, be sleeved on the left driven wheel engagement Left Drive gear driving gearshaft 44 on and left output shaft 39 on of left steering gear by being engaged with, be sleeved on the right driven wheel engagement right travelling gear driving gearshaft 44 on and right output shaft on of right turn gear by being engaged with, thereby hull 19 and roller 32 are fallen back or advance with certain grade of speed.

Because of being hinged on left steering bar 3 on the frame 21 by the connection that matches of the left steering gear on the tooth sector axle 43 of steering link 20 and gearbox 11, right turn bar 26 is by the connection that matches of the right turn gear on the tooth sector axle 43 of steering link and gearbox 11.When needs turn left, left steering bar 3 is pulled back, make the left steering gear of gearbox 11 break away from engagement with the travelling gear that is sleeved on the tooth sector axle 43 by steering link 20, thereby left wheel is stopped operating, and this moment, right turn gear and travelling gear still meshed, thereby right roller is rotated further, and makes hull 19 to left movement.In like manner, when needs were turned right, only need pull back right turn bar 26 and get final product.

The utility model also can be installed disk plow, plough arm rotating shaft 22 is sleeved on frame 21 or the hull 19, the upper end of hold-down arm 30 is affixed with plough arm rotating shaft 22, and plough 29 is installed in the lower end, and the end that arm 23 is turned round in rotating shaft and the plough arm rotating shaft 22 affixed other ends join by connecting rod or backguy and plough lift control lever 25.By handling that plough lift control lever 25 makes hold-down arm 30 backspins and disk plow is transferred and farming, adjust tilth by the different angles of adjusting hold-down arm 30, also can make and revolve on the hold-down arm 30 and break away from farming face and disk is not worked,

When need are walked on road, can be at the outside of two rollers 32 suit road wheel 13, and front-wheel 1 is installed and is turned to handrail 2 at hull 19 front ends, at this moment walking and steering operation are convenient.Be sleeved on the front-wheel 1 of hull 19 front ends and turn on the handrail 2 brake assembly can be installed, so that realize braking control.
