Description

Nonirrigated farmland plough, sowing hand tractor

Technical field

The utility model relates to a kind of agricultural machinery, especially hand tractor.

Background technology

Existing hand tractor is generally by diesel engine, transmission mechanism, front driving wheel, trailing wheel, steering control device, the cultivated girder of seat, plough or rotary cultivator attachment etc.Structurally all compact, the operation light and flexible, and reliability and adaptability are all better, the driver can sit straight and carry out the ploughing operation on the hand tractor operative position, also can fully be used for communications and transportation, draw water and field management etc., greatly reduce peasant's labour intensity, improve labor productivity, therefore, on agriculture and forestry, be used widely.But also have following weak point: the wheelspan of (1) two front-wheel is little, and is stable inadequately in tiltedly steep nonirrigated farmland operation walking.(2) rubber tire wheel face width before and after original-pack the dispatching from the factory, contact-making surface is big, and it is unhappy to run into loose and thicker surface dust sinking, and it is not enough to make consumption make the degree of depth, only 6～8cm.And the original-pack paddy field iron tyre that dispatches from the factory is too high, and area contiguously is wide, and the consumption cutter that revolves that hand is dragged does not reach the effectively degree of depth, can not use when the operation of nonirrigated farmland.(3) the original-pack ploughing device that dispatches from the factory consumes device because effect is different with revolving, and will load onto the ploughing device when ploughing; When the need rotary tillage, then to pull down the ploughing device, just can load onto rotary cultivator attachment, hand drags machine just can carry out the rotary tillage operation.Both needs are torn open mutually or are adorned, and use inconvenient.(4) former hand tractor is not provided with seeding apparatus, is unfavorable for ploughing broadcasting integration of operation.

Summary of the invention

The purpose of this utility model provides a kind of nonirrigated farmland plough, sowing hand tractor, and it should be able to overcome in the nonirrigated farmland shortcoming that tiltedly steep operation walking can not be stablized, depth of implements is not enough, can plough and rotary tillage and plough and sowing operation simultaneously.

The hand tractor that the utility model provides comprises front wheel driving wheel shaft, the cultivated girder of seat, plough or rotary cultivator attachment, and diesel engine and transmission mechanism and direction-control apparatus, it is characterized in that also comprising:

(a) respectively with former before the loose joint wheel hub that is fixedly connected of two-wheeled wheel hub;

(b) be fixedly connected nonirrigated farmland iron tyre on two loose joint wheel hub outer ends;

(c) the tail iron tyre of replacement protocercal tail trailing wheel;

(d) be located at the tail iron tyre and be fixed on the plough of starting of sitting cultivated girder downside before;

(e) the tail load bar that is fixedly connected by an end and the cultivated girder of seat is arranged on the seeding apparatus that tail is carried on a shoulder pole the bar other end and sat the basin back; This seeding apparatus obtains power by belt gear at front axle, realizes sowing automatically.

The nonirrigated farmland plough of said structure, sowing hand tractor, on former front-wheel hub again adjunction the loose joint wheel hub, increased the wheelspan of two front-wheels, and, nonirrigated farmland iron tyre and tail iron tyre kiss the earth area are little, run into pine or surface dust and sink, reduced the center of gravity that hand drags very soon, make it the balance of on tiltedly steep nonirrigated farmland, walking.Between rotary cultivator attachment and tail iron tyre, installed additional and started plough, made rotary tillage and start and to carry out simultaneously, and owing to be provided with seeding apparatus, rotary tillage, started and sow and to carry out simultaneously.Like this, in dry farming, can save time, few power and energy savings are increased work efficiency, and reduce labour intensity, liberate the productive forces, and are the good harvest of China's agricultural, realize the mechanization of farm work and make contributions.
