Description

The light-duty cultivator in paddy field

Technical field

The utility model discloses a kind of underwater cultivation (comprising plough, rolling is Pu, flat, down together) machinery, the light-duty cultivator in especially a kind of paddy field.

Background technology

The underwater cultivation machinery of prior art has multiple, as tractor, boat tractor, harvesting and tillage machine etc.Remove defective is alone respectively arranged, big as the tractor manipulation strength, the boat tractor hull bottom is easy to wear and when traction is monolateral and the belt serious wear, and the harvesting and tillage machine single wheel drives and easily turns over machine and cause outside the personal injury accident etc., tractor and harvesting and tillage machine also exist driving wheel to destroy at the bottom of the field, fall into the defective of car easily.Their common defects is: volume is big, and machine self is heavy, and favourable turn (going to another piece field from a field) difficulty all only is applicable to the bulk paddy field of flat-bottomed land only to be applicable to that also between twenty and fifty people manipulates.Above tillage machinery both be not suitable for the fritter terraced fields in mountain area, hills, the more between twenty and fifty big portion in inapplicable present rural area go out to do manual work and the present situation in the stay-at-home rural area of child old man women.

The utility model content

The technical problems to be solved in the utility model is, overcomes above the deficiencies in the prior art, provides a kind of paddy field light-duty cultivator, this body is long-pending little, in light weight, favourable turn easily, operate nimble (convenience) laborsaving, do not destroy at the bottom of the field, be difficult for falling into car, it is little to wear and tear, and security performance is good, and cost is low, be applicable to mountain area, hills fritter terraced fields, and old man, women can operate all.

Technical solution of the present utility model is, a kind of light-duty cultivator in paddy field with following structure is provided, and it comprises diesel engine, gearbox, frame, arm-rest frame, plough, driving rolls, field-finisher, arrangement of clutch etc., and it also comprises supporting ship; Described driving rolls double as Pu is rolled, and promptly is provided with the some blocks of broken mud plates of strip on the circumference of wheel; Described driving rolls is 2; Described frame is fixed on the waist of gear or chain wheel-speed regulating change box; Described supporting ship is fixed on the frame front lower place, and the supporting forward quarter has the detachable connecting device that field-finisher is installed; Described diesel engine is located at the front upper part of frame, and driving-belt connects the output wheel and the gearbox wheel for inputting of being located at gearbox top of diesel engine; Described 2 driving rolls are installed in to be located at the gearbox bottom and to stretch out on the output shaft of gearbox both sides; Described arm-rest frame is connected with the upper back of frame; There is the detachable connecting device that plough is installed at the rear portion of described frame.

After adopting above structure, the light-duty cultivator in the utility model paddy field is compared with the underwater cultivation machinery of prior art, has following remarkable advantage and beneficial effect:

One, owing to cancelled seat people part, driving rolls and Pu wheel (whole field wheel) unite two into one, plough and field-finisher all can be dismantled, required diesel engine horsepower is little (only to need 160 diesel engines, 1.65 kilowatt get final product, and original tiller needs 4-8 kilowatt) etc., this body amasss little, in light weight (complete machine weight is no more than 60 kilograms), cost low (price only be a head of cattle price 1/2).

Two, because frame is located at the waist (centre of height) of gearbox, and its center of gravity is low, and driving rolls is a left and right sides two-wheel in addition, so, being difficult for overturning, its security performance is good, and it is little to wear and tear.

Three, because roller adopts the broken mud plate contact of strip mud face, and roller is a two-wheel, and complete machine weight is lighter, and compressive load per unit area is little in addition, so, be difficult for falling into car, can not destroy at the bottom of the field yet.

Four, because own wt is light, volume is little, can walk at ridge, in addition supporting ship ditch more or on can make fulcrum in the process such as ridge and (replacing other people to lift complete machine) lift arm-rest frame complete machine got over ditch or turned over bank, so favourable turn is easy, convenient, a people both can operate.

Five, because above advantage, utilizing supporting ship to make fulcrum can replace Pu to roll ship (boat tractor) operation with farming field angle fritter with after utilizing supporting ship to load onto earth to gain in weight and not need advantages such as the people operates in addition in pivot turn, tune, field-finisher is contained in the front and makes sight line brighter and clearer in addition, advantages such as angle, field fritter etc. all can flatten, so, this machine operation is nimble laborsaving, and the elderly, women all can operate, and extensively is adapted to the plough, Pu of mountain area, hills fritter terraced fields, flat farming.

As improvement, can establish the device of lifting plough, the time spent does not rise to off position in short-term at plough; Can establish and regulate the bury device of the depth of plough point, to adapt to the needs of the different depths at the bottom of the field; Also can set up the device of regulating the arm-rest frame height, to adapt to the different human needs of height.More than improving all makes this machine operation more convenient, more laborsaving.

As further improvement, plough can be contained in the middle left or right position of frame posterior transversal, and be convenient to plough limit and Tanaka make this machine be more suitable for the fritter terrace cultivation.

As further improving, arrangement of clutch can have work, stopped status lock function concurrently again, and the setting of dashboard and restriction frame terrain clearance make this machine security performance better less than 45cm (restriction height of C.G.).
