Description

The multifunction micro motor plough

The utility model relates to miniature walking formula tractor technical field, especially a kind ofly plows in narrow and small field, can drive rotary tillage mechanism again and plough, and can also provide the multifunction micro motor plough of power for drawing water, beat farm implements such as rice, abrasive dust.

For a long time, hand tractor is with simple in structure, operate light, price is low, supporting with relevant farm implements, can plough, rake, insert, trench diggings such as receipts, mobile operatings such as level land, can also draw water, generating, grind paddy, threshing, fixed operations such as oil expression, be widely used in the mountain area, the nonirrigated farmland, Plain, also exist simultaneously and can not cross ridge, the defective that can not go up a slope, ZL97237687.9 patent have proposed to travel and have partly connected the drive sprocket that travels by output in the middle of the gearbox bottom, place ground before, back guide wheel, the technical scheme of the triangle transmission traveling mechanism that the loop chain crawler belt constitutes has solved above-mentioned defective, but still exists following shortcoming: 1 chassis transmission device is traditional V belt transmission device, must cause the power transmission loss big, belt easily skids; The weight of left side belt pulley flywheel is taken back structural focus, easy overturning during operation; Turning to of 2 chassis is still to adopt castellated steering cluth, by stirring clutch dog compression clutch dog spring, itself and final drive pinion are thrown off, power is cut off and realizes turning to, cause hand tractor when plowing, to turn to by manually lifting, in case any one side, wheel or crawler belt blocked by careless foreign material, flame-out easily, use very heavy and inconvenient.

The purpose of this utility model provides a kind of multifunction micro motor plough, and it accomplishes that not only chassis structure is reasonable, and is in light weight, and power loss is little and the turning of plowing is very convenient flexibly, can overturning not be difficult for stopping working, in the hope of overcoming the shortcoming that above-mentioned hand tractor exists.

The purpose technical scheme that realizes the utility model is such: a kind of multifunction micro motor plough, comprise diesel engine 1, chassis 2, transmission loop chain crawler belt and guide wheel 3 travel, vehicle frame and arm-rest frame 4, the mechanical type hitch 5 of plough, rotary tillage mechanism 6 is characterized in that the travelling gear 2.1 of I axle in the chassis, the driven gear 2.2 of II axle and the power wheel 1.1 of diesel engine 1 have constituted non-belt drive unit; Turning in the chassis is to have adopted differential gear 7, and rotary tillage mechanism 6 is by dismountable roller 6.1 that revolves, the axis hole 6.2 of the wounded in the battle key of X axle, and the travelling gear 6.3 of IX axle constitutes; The travelling gear 2.1 of described I axle respectively with the driven gear 2.2 of the power wheel 1.1 of diesel engine 1, II axle, chimeric being connected; The roller gear 7.1 of described differential gear 7 is meshed with the travelling gear 2.12 of VIII axle and obtains power, and its semiaxis outer end connects the drive sprocket 3.1 that hangs crawler belt; Travelling gear 6.3 on the IX axle of described rotary tillage mechanism 6 is meshed with the roller driving wheel 2.10 that revolves of IV axle in the chassis 2, the roller driving wheel 12.10 that revolves of described VI axle is to be meshed with the driving wheel 2.7 of IV axle by the driven gear 2.8 that coaxial driving gear 2.9 connects the V axle, and acquisition power.

Take technique scheme to make successful multifunction micro motor plough and overcome the problem that general hand tractor exists for a long time, have fairly obvious advantage: 1 adopts non-belt drive unit, weight obviously alleviates, complete machine weight is about 85 kilograms, reduce weight 26.7%, the structural focus equilibrium, the phenomenon of overturning left when not having operation.The loss of 2 power transmission is little, and maintenance is convenient.3 adopt differential gear, and the very light and flexible of turning of travelling, plow can be at 10m ²About the field on farming, more can be because of turning, mud grass card crawler belt and stopping working.4 dismountable rotary tillage mechanisms, for supportingly plough, harrow, insert, farm work such as receipts, trench digging, level land provides convenience.

Below in conjunction with accompanying drawing, provide embodiment, and be further described.

Described gears engaged schematic diagram in the transmission case body of Fig. 3 chassis.

From Fig. 1, Fig. 2, Fig. 3 as can be seen, the triangle driving pulley in diesel engine 1 left side of described multifunction micro motor plough is cancelled, the substitute is the power wheel 1.1 of diesel engine 1, the belt pulley of corresponding utilization on the right side of diesel engine 1 then can satisfy the power needs of matched farm tool as drawing water, thrashing, and the defective that center of gravity is taken back is repaired; Described power wheel 1.1 is meshed with the travelling gear 2.1 of I axle in the chassis 2, the travelling gear 2.1 of I axle is meshed with the driven gear 2.2 of II axle again, formed non-belt drive unit, it is to be noted and on driven pulley 2.2, be equipped with the flexible rubber shock absorbing ring, thereby constitute the flexible transmission of II axle, power passes to the driven gear 2.2 of II axle fast from diesel engine 1 driving wheel 1.1, power loss is very little, and described transmission device is in sealing device, the phenomenon of belt creep has thoroughly been abandoned in maintenance easy to lubricate.It can also be seen that from figure, power can be sent to the astern wheel 2.5 of IV axle or pass to mobile change pulley 2.6, the driving wheel 2.7 of IV axle by the friction disk clutch driven pulley on the II axle 2.3,2.4, the speed retaining of motor plough described here is distinguished by mobile change pulley 2.6.Driven pulley 2.8 on the V axle is being close to driving wheel 2.9, if driving wheel 2.7 promptly passes to driving wheel 2.9 with the fast retaining of driven pulley 2.8 engagements power, in addition, described VI axle is provided with and revolves roller driving wheel 2.10; The travelling gear 6.3 of the described rotary tillage of driving wheel output wheel 2.11. mechanism IX axle just in time is meshed and obtains rotary tillage power with the roller driving wheel 2.10 that revolves of VI axle, driving wheel output wheel 2.11 is meshed with the travelling gear 2.12 of VII axle, travelling gear 2.12 is meshed with the roller gear 7.1 of differential gear 7 again, it is emphasized that the important function that differential gear is brought into play especially in said motor plough, not only overcome the heaviness that hand tractor plows and turns and need manually move fully, and when one side crawler belt is blocked by the weeds foreign material, engine can be therefore not flame-out, and the predicament of can getting off quickly, really realized the characteristics that motor plough is flexible to operation.Described rotary tillage mechanism 6 by the axis hole 6.2 that has spline make revolve roller 6.1 can be for convenience detach, for the various supporting parallel mobile farm implements of custom replaceable provide convenience, alleviated the weight of motor plough simultaneously greatly.Diesel powered described in the utility model is 2.5～3.6 kilowatts, long (Armrest) 1.7M of fuselage, wide 0.6M, high 0.9M per hour ploughs 0.7～0.8 mu, preposition single ploughshare, 20 centimetres of the degree of depth of plowing, narrow and small field farming that can be about 10 square metres, two crawler belts can be climbed the slope below 45 °, farming turning light and flexible can the original place three-sixth turn.
