Description

Middle-size and small-size maneuver plough

Technical field

The utility model relates to a kind of agro-farming and dig, in particular motor-driven driving plough tool with the plough tool.

Background technology

The plough tool is widely used as traditional cultivating implement.Occurred diversified plough tool improvement technology in recent years, and according to different technical purposes, its structural design form is also various, each has something to recommend him, technique effect also has nothing in common with each other.But in the plough global design, the ubiquity structure constitutes complicated and the irrational technical problem of each component distribution, and cause housing construction huge, can't satisfy the diversity of farming operating environment, particularly existing driving wheel structure has adopted the sour jujube plate structure that is fixed in same rotation direction on the wheel bobbin, this structure has increased the driving resistance, can't operate operation in the arable land of soft soil property, also gives to turn to and has brought very big difficulty.

The utility model content

Easy to operate middle-size and small-size maneuver ploughs such as goal of the invention of the present utility model is to provide a kind of compact conformation, light and handy, shovel time operation, turn to.The middle-size and small-size maneuver plough technical scheme that the utility model patent application provides, its major technique content is: a kind of middle-size and small-size maneuver plough, it mainly includes the plow frame body, the horizontal plow frame body of this plow frame body is provided with driving pawl, the driving pawl front end support wheel with being provided with holding up of engine and both sides, its underpart, be positioned at the gearbox that driving pawl one side is provided with the engine variable speed drives, its horizontal plow frame body is provided with operation handrail frame by one section lift carriage, being connected to this operation handrail by gearbox is provided with the clutch control operating rod and handles handrail, in switching place of horizontal plow frame body and lift carriage the ploughshare setting is set and turns the hinged rotating shaft that frame and plow frame sports association connect, turn to be provided with between beam at handrail frame and this ploughshare and be used to handle the trussed beam that rises of adjusting the ploughshare working depth, evenly be fixed with the ratchet bar that some cross sections are dihedral along the driving pawl circumference.

The middle-size and small-size maneuver plough technical scheme that the utility model provides, because having changed conventional ADS driving, present technique takes turns the sour jujube plate structure that lands, it is reliable more, strong that the structural design of its driving pawl not only makes landing of driving wheel drive, and driving wheel rotate in landing part and the transition portion of its ratchet that lands all be to be that face contacts with ground, reduce ground and born pressure, so can be suitable for farming use on the arable land of different condition, it is applied widely, also greatly facilitate the complete machine steering operation, for peasant household provides operation, uses more flexibly, ploughed easily and plough.This middle-size and small-size maneuver plough overall structure is simple, in light weight, the weight configuration of plow frame body front and back is reasonable, so the operator exerts pressure to handrail slightly, just can finish the ploughing operation of appropriate depth, more since its fuselage width reasonable in design, more can be suitable for after crop grows tall the arable land making ridge, the shovel time or the intertill and clean tillage operation.
