Abstract

The utility model discloses a light portable reciprocating double-wheel plow harrow tillage machine, comprising a plowshare part and a road wheel. The utility model is characterized in that the utility model also comprises a plowed depth regulator, rockers, a plow frame, a road wheel, a transmission shaft, a transmission wheel, a wheel sleeve, a ratchet and pawls. With the principle adopted that inscribed teeth of the ratchet mechanism are in mesh, the utility model adopts a shaking pressure arch rod and a pull rod of pull pawls to drive a big sprocket that is transmitted to a star pinion arranged on the transmission shaft by chains so as to drive a grounding road wheel to plow. With wide adaptability, simple structure, safety and reliability, the utility model has the advantages that the utility model can be applied in plains as well as in narrow dry lands and paddy fields in the hilly areas; and the utility model not only saves energy and livestocks but also overcomes the disadvantage that the cultivated soil is compacted by the traction machinery for a long time, thereby relieving the labor intensity of the farmers.

Description

Two-wheel plow harrow tiller

Technical field

The utility model relates to a kind of agricultural machinery, the two-wheel plow harrow tiller without power in mountain area, particularly a kind of suitable hills.

Background technology:

In general, in the flat-bottomed land, the farming plow harrow that the field is used, major part all is to use diesel engine, electromotor etc. drive as power, yet, because the complex structure of this plow harrow machinery, too heavy, so, in narrow field, mountain area, hills, the farming plow harrow is still come with ox in most of area, all must put into a large amount of energy and material resources in the cowboying every year to the peasant who makes the mountain area, at this situation, someone has invented novel plow harrow machine relatively simple for structure, as: small-sized pushing walking hand plough-harrow machine (patent No.: 03250320), it is characterized in that: it reductor as frame, the hinged colter of its front end, its upper end is connected with engine by spline, the fixedly connected arm-rest frame in its rear end, and arm-rest frame is equipped with backguy, be used to operate the throttle of engine, fixedly connected two drives impeller in the two ends of the gear output shaft of reductor.And for example: the Chain driven plow-harrow machine (patent No.: 99237653), comprise chain, sprocket wheel, shift fork, driving cucurbit, plough body, gasoline engine, petrol tank, stay cord, bevel gear, starting handle, chain drive-belt spud pile, be characterized in: drive cucurbit and meshing the chain drive-belt walking under the drive of gasoline engine and driving chain, sprocket wheel, also corresponding the advancing under the driving of gasoline engine of plough body does to plough an operation that harrows a field.Cooperate the chain walking with driving cucurbit, saved wheel.Though the weight of above plow harrow machine alleviates to some extent, but be unable to do without heavy engine, so, also be far from reaching the requirement of hill farmer.Therefore, design in area, mountain area, hills, the peasant can use in the fritter field, without ox, without diesel engine, electromotor; Not power consumption, overall dimensions are little, simple in structure, and the plow harrow machine that cost is low is people's a an urgent demand.

Summary of the invention

The purpose of this utility model is utilized the principle that connects tooth-type in the ratchet mechanism, press arch bar to press, draw the ratchet pull bar to drive hinge wheel to shake, drive the ground-engaging wheel by the minor sprocket of chain biography on power transmission shaft and carry out plow harrow work, provide a kind of light to people, can be in the flat-bottomed land, the portable reciprocating type two-wheel plow harrow tiller that also can in narrow nonirrigated farmland, mountain area, hills, paddy field, use.

The utility model comprises the plow harrow parts, road wheel, be characterized in: this tiller also comprises the plow-depth control device, rocker shaft, frame, rocking bar, draw lacing film, driving shaft, ratchet, hinge wheel, power transmission shaft, minor sprocket, chain, ratchet, drive, wherein the plow harrow parts connect with frame, the plow-depth control device is installed between them, two rocking bars are connected on the rocker shaft, draw lacing film to be installed on the driving shaft, also be with ratchet on the driving shaft, hinge wheel, drive is installed on the power transmission shaft, drive has ratchet, ratchet also is installed between the two, and chain is enclosed within on hinge wheel and the minor sprocket, and road wheel is installed on the power transmission shaft.

The utility model has following advantage:

1. wide adaptability.Provide a kind of light, be convenient to promote the popularization use, can be in broad area, length and breadth of land Plain, the also small-sized farming plow harrow machine that can in narrow paddy field, mountain area, hills, nonirrigated farmland, use, since the plow-depth control device not only can up-down adjustment the tilth of plough, rake, can also left and right adjusting the plowing direction of plough, rake, so, this two-wheel plow harrow tiller can plow harrow to each corner in field.

2. simple in structure.Easy to manufacture, cost is low, volume is little, body weight is light, easy to carry, energy savings, saving livestock, cost is low, especially because this device is portable reciprocating structure, overall dimensions is little, eliminated for a long time, big model plow harrow machine moves inconvenience, and is special in darker paddy field during operation, often be absorbed in the earth, and the soil after the farming is pulled the defective of mechanical ramming.

3. safe and reliable.Because this mechanism is without ox, horse, without the power of electromotor, diesel engine, so, using reliable, job safety, favorable working performance, easy to operate, the men and women all can operate, easy to maintenance, the labour intensity of having liberated the peasant greatly.
