Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of agricultural cultivator tool, particularly a kind of mini-size tillage machine.
Background technology
Mini-size tillage machine is a kind of agricultural equipment for carrying out farming operation to farmland, and it has the features such as lightweight, volume is little, structure is simple, user-friendly and deposit, be widely used in Plain, mountain area, hills nonirrigated farmland, paddy field, orchard etc. farming in.Mini-size tillage machine mainly with small diesel engine or gasoline engine for power, also can carry out after mixing corresponding utensil drawing water, generate electricity, spray the operation such as medicine, spray, also can draw towed vehicle and carry out short-distance transport, freely can travel in field, solving the worry that large-scale farm machinery cannot enter field, mountain area, is that vast farmers consumer substitutes the cultivated optimal selection of ox.
Existing mini-size tillage machine promotes painstaking, inconvenient operation, cultivated land weak effect problem of walking.As Chinese patent application (notification number: CN 2316798Y) discloses a kind of miniature rotary cultivator, primarily of headstock, diesel engine, gearbox, walk, drive handle, chain cover, revolve blade row plough, depth control device composition, headstock is equipped with diesel engine, speed changer, travelling wheel and driving handle, after headstock, is connected with chain cover, revolve blade row plough, depth control device and splash-back etc.Travelling wheel and the depth control device of above-mentioned miniature rotary cultivator all together land, and are unadjustable switching between the two, and need up to lift handrail during walking and make depth control device depart from ground, operation is comparatively inconvenient, painstaking; And it does not have special cultivated cutter, is completed by travelling wheel the farming in field yet, the effect of cultivating is poor.
And for example Chinese patent application (notification number: CN 2720786Y) discloses a kind of Miniature rotary hand tillage, its gearbox is contained in above the middle part of frame, engine is arranged on gearbox front end above frame, handrail connector is housed above gearbox rear end, handrail connector rear end is provided with handrail, the power take-off of gearbox is arranged on gearbox lower end, and this output shaft overlaps wheel-mounted or cultivated cutter, depth adjustment bar is contained in frame rear end; The power take-off of engine is directly contained on the clutch in gearbox, and gearbox sends device built with clutch, device is sent in gearshift and reverse gear sends device, and handrail is equipped with gear level, Oil Switch, clutch handle and reverse gear handle.Wheel and the cultivated cutter of above-mentioned Miniature rotary hand tillage are installed separately, and wheel installed by cultivated cutter of need dismantling during walking, and cultivated cutter installed by wheel of then dismantling during farming, and operation comparatively bothers.The depth adjustment bar of this rotovator is one and touches can't regulate with ground simultaneously, needs up to lift handrail when walking and makes depth adjustment bar depart from ground, operation comparatively inconvenience, painstaking.
And for example Chinese patent application (notification number: CN 202160386U) discloses a kind of roller support mechanism for micro rotary tillage machine, and it comprises roller, transmission mechanism, support transverse slat, degree of depth connecting rod, connecting hole, connection rivet, transverse slat internal chute and wheel shaft; Degree of depth connector is provided with in the middle part of wheel shaft between roller, degree of depth connector is provided with several connecting hole, support transverse slat front end and be provided with transverse slat internal chute, degree of depth connector is fixed by rivet and connecting hole through internal chute, supports transverse slat end and is connected with transmission mechanism.This rotovator is when farming and walking switch, and what needs were exerted oneself lifts roller, then degree of depth connecting rod is pulled lower support, and whole handoff procedure is comparatively painstaking, and operation also comparatively bothers.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of convenient, labour-saving easy and simple to handle mini-size tillage machine of walking.
Object of the present invention realizes by following technical proposal: a kind of mini-size tillage machine, comprises support; Be positioned with cultivated cutter below described support, be fixed with above support to drive and plough the dynamic internal combustion engine of swivel, described support is fixed with handrail; It is characterized in that, be provided with support, described support be positioned with tilling depth adjusting part and wheel, be articulated and connected between described support and support by jointed shaft on rear side of described cultivated cutter, described support is provided with the limit journey assembly for limit bracket oscillating stroke.
This mini-size tillage machine can the support of installing wheel and tilling depth adjusting part by arranging on support, by being articulated and connected between support and support, tilling depth adjusting part and wheel can only one and earth surface, tilling depth adjusting part and the switching of wheel when achieving walking or farming, i.e. wheel and earth surface during walking, tilling depth adjusting part and earth surface during farming, when well solving walking, wheel and tilling depth adjusting part land the inconvenience caused simultaneously, light pressure handrail driven forward is only needed to walk, operation more for convenience, laborsaving, installation and removal during maintenance also more for convenience.Meanwhile, be also positioned with special cultivated cutter below the support of this mini-size tillage machine, the effect of farming is better.
In above-mentioned mini-size tillage machine, described limit journey assembly comprises the locating part two being arranged on the locating part one of side oscillation stroke and the limit bracket side oscillation stroke backward forward of limit bracket on support.By support, around jointed shaft, side oscillation is to leaning with locating part one forward, and now wheel wheel face and ground lean, and tilling depth adjusting part departs from bottom surface, and this state is applicable to promoting mini-size tillage machine walking.By support around jointed shaft backward side oscillation lean as locating part two, then wheel depart from ground, tilling depth adjusting part and ground lean, this state be applicable to plough plough operation.
In above-mentioned mini-size tillage machine, when described support and locating part one lean, wheel hub is between jointed shaft and cultivated swivel axle.When support and locating part one lean, wheel and ground lean, and wheel hub is between jointed shaft and cultivated swivel axle, thus make whole mini-size tillage machine have the trend retreated, when promoting mini-size tillage machine walking, only need press down handrail gently and push away forward, what operate more is easy, laborsaving.
