Description
Technical field
The utility model relates to a kind of parts of agricultural machinery, particularly double-screw type farming propeller.
Background technology
China is a large agricultural country, but farming utensil aspect, especially plow harrow that the ancestor hands down etc. is also taken in south, because south is with a varied topography, the mountain area is arranged, the hills, the branch in Plain, the rice field complexity has size, do wet, the depth, soft or hard is not, make large-scale tillage machinery be difficult to exercise one's ability, can only use middle-size and small-size tillage machinery, but the workpiece in the present tillage machinery remains plow harrow, the someone attempts to use helical element to replace old-fashioned farming utensil in recent years, contemporary for wheel, they explore, and propose some schemes, and its weak point is, single-screw can not force balance in earth, can only do irregular movement; Single double helix generally all adopts the fan-type blade, and its rigidity is difficult to bear the huge torsion in the earth; The problem of advancing in all unresolved dry ground fortunately of single double helix, the scope of application is limited to the paddy field; The effect of fan-type blade is limited to incision earth, propelling machinery, and still needing is provided with cultivating member such as plow harrow harrow-like implement for pulverizing soil etc.
Summary of the invention
The purpose of this utility model is to overcome the disadvantages of background technology part and proposes two double-screw type farming propellers.This utensil is applicable to various agricultural machinery, combines with prime mover, transmission mechanism, operating mechanism etc., can substitute old-fashioned cultivator tool effectively, and advance this machinery neatly; First of the present utility model is applicable to dry ground, and second is applicable to paddy field and wet soil.
The utility model is taked following technical proposals for this reason: the spiral of establishing some, rotation directions parallel to each other to axis and switched in opposite, thread depth can increase and decrease, the spiral front end is equipped with the self-tapping type parts, if some axles are parallel to each other to line, the hollow shaft of switched in opposite, be wound with the screwer that highly can increase and decrease on the every hollow shaft, rotation direction is opposite each other for the screwer on the every pair of hollow shaft, and several farming parts are equipped with on the screwer or hollow shaft surface.
The utility model is compared the beneficial effect that background technology has: because taked double-screw type and improved helical member shape and structure.So guaranteed the rigidity of these parts, it can be advanced in earth smoothly; Owing to taked self-tapping type, solved the problem of in dry ground, breaking ground and advancing, make the utility model both be applicable to paddy field and wet soil, also be applicable to dry ground; Owing to be provided with multiple farming part, make the utility model not only can substitute wheel, can also substitute old-fashioned cultivator tool; Since of the present utility model open, from then on can collect farming and gather in a machine, will significantly improve agricultural production efficiency.
