Background technology

Mini-size tillage machine is a power with small diesel engine or gasoline engine, has in light weightly, and volume is little; Characteristics such as simple in structure adaptable across the Plain, the nonirrigated farmland on mountain area, hills, paddy field, orchard etc., are mixed corresponding facility and can be drawn water, generate electricity, spray operations such as medicine, spray; Also can draw towed vehicle and carry out short-distance transport; Mini-size tillage machine can freely be exercised in the field, user-friendly with deposit, saved the worry that large-scale farm machinery can't get into field, mountain area piece.

Mini-size tillage machine of the prior art has unicity on function, in the time of promptly need carrying out a certain work, must shut down and change corresponding facility, because its power output is single, replacing facility not only consuming time have also reduced operating efficiency simultaneously; Simultaneously, because the characteristic of its handrail itself has significant limitation when some special landform work,, increased workload as reversing end for end or turning to inconvenience etc.

The utility model content

The utility model for solve existing mini-size tillage machine outputting power single and when some extreme terrain uses the big problem of limitation; A kind of full landform multipurpose mini-size tillage machine is provided; This machinery has two different clutch ends; Simultaneously, handrail also can omnibearingly turn to, and has improved the adaptability of mini-size tillage machine to different facility and landform greatly.

The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of full landform multipurpose mini-size tillage machine; Comprise arm assembly, gearbox, manual friction clutch, body and engine; Described gearbox comprises two planetary gearsets, active force output shaft, secondary power take-off, force transmission shaft, walking axis and power shift gear group; The power of engine output is connected to the power shaft of gearbox through manual friction clutch; Power shaft successively through two planetary gearsets with transmission of power to active force output shaft, secondary power take-off is parallel with the active force output shaft respectively with force transmission shaft, secondary power take-off is connected through driving gear set with the active force output shaft; Force transmission shaft is provided with the power shift gear group; The power shift gear group is meshed with the gear train that the active force output shaft is provided with, and walking axis and force transmission shaft are perpendicular, and is connected through angular wheel;

Described arm assembly comprises arm-rest frame, horizontally rotates seat and height adjustment wheel; The described seat that horizontally rotates is connected with body through vertical rotating shaft; Height adjustment wheel is for semicircle, and is fixed on an end of arm-rest frame, and the height adjustment wheel is connected with horizontally rotating through horizontally disposed rotating shaft; On the wheel rim of height adjustment wheel, be evenly distributed with detent, horizontally rotate seat and be provided with the alignment pin corresponding with detent.

In the utility model, also be provided with clutch on the active force output shaft, clutch be arranged on and power shift gear group meshed gears group and driving gear set between the position.

In the utility model, be provided with on the walking axis turn to, the forward-reverse clutch, through stirring the clutch shifter on any one side, transmission of power is broken away from, make rotating speed on one side reduce, thereby reach the purpose that turns to; Combination through changing bevel gear and clutch with separate the counter-rotating that makes power and determine retreating or advancing of mini-size tillage machine with just transferring.

In the utility model, handrail can be done the rotation of wide-angle around vertical rotating shaft through horizontally rotating seat in horizontal extent, simultaneously; Height of armrests can be through the adjustment of height adjustment wheel; After adjustment finishes, insert through alignment pin in the detent of respective heights, to fix and to keep this highly.

Be provided with two groups of planetary gearsets in the gearbox, can more accurately change gearratio flexibly, make the facility of the kinetic force better matching drive of output, satisfy agriculture requirements different on the different landform.

The effect of manual friction clutch be when reducing to shift gears to the impact of planetary gearsets, the protection gear train.

After power shift gear group and the gear train engagement, form different gearratio output, can change the rotating speed of walking axis, thereby change the gait of march of mini-size tillage machine.

Two gear numbers of teeth of the driving gear set of connection active force output shaft and secondary power take-off are different, cause the rotating speed of two power take-offs outputs different, can satisfy different facility demands.

On the active force output shaft and power shift gear group meshed gears group and driving gear set between the position clutch is set; Its effect is to cut off power output; Like this when changing facility without shutting engine down, but change accomplish after on-line operation, improved operating efficiency.

Beneficial effect: the utility model adopts unique handrail design, make among a small circle in the turning to conveniently of handrail, flexibly; Be provided with two groups of planetary gearsets in the gearbox, can change gearratio more flexibly, satisfy different gardening requirements; Double dynamical output can be used to different gardening facility are installed, and has improved operating efficiency; Through above design, the utility model can satisfy landform and gardening requirement arbitrarily, particularly under situation with a varied topography, and still can operate as normal.
