Description

A kind of self-propelled minisize plough

Technical field

The utility model is related to plough technical field, particularly to a kind of self-propelled minisize plough.

Background technology

China is a large agricultural country, has the cultivation culture of thousand of years, in traditional Farming Culture, employment and livestock The agronomy drawing plough plowed soils has just been used thousand of years.In recent years, with the raising of Tendency of Agricultural Machinery in China level, in Plain Area and entirely block, this agricultural is substituted completely by four-wheel tractor and hand tractor traction turnplow or disc plough ?；But, nearly ten years, in mountain area, peasant in order to save man-hour, in the case of there is no suitable plough, using miniature plough Cultivated machine progressively substitutes traditional ploughing.

Because mountain area physical features is uneven, thus, it is ensured that miniature plough stablizes operation it should be ensured that the drive of miniature plough Resistance between driving wheel and soil, wherein mainly driving wheel grab ground ability.

The driving wheel of existing self-propelled minisize plough mainly has three kinds of forms: the first is the cylindrical driving for tire Wheel, the resistance between tire and soil is less, easily skids in the soil that humidity is larger or viscosity is larger；Second is outer Circle installs the driving wheel of rectangular slab, and the resistance and soil between is good compared with tire, but for the harder soil of soil property, however it remains It is difficult the shortcoming buried；The third is the cylindrical driving wheel installing double helical tooth, the China of such as Publication No. cn203681131u Utility model patent discloses a kind of micro-cultivator walking wheel device, and double helical tooth is fixing on the supporting plate, and is tied by cross The reinforcing plate of structure fixes double helical tooth and gripper shoe although the ground ability of grabbing of double helical tooth grabs ground ability by force than rectangular slab, but from Clearly find out in the Figure of abstract of this patent, the outer face of double helical tooth is generally flush with, and still has and is difficult in harder soil The shortcoming buried.

Further, since it is more to laying of markstone in soil in the arable land of mountain area knob, plough point is easily pushed up and is laying of markstone, and leads to miniature Plough cannot normal operation.Only pass through in existing plough screw mandrel and nut cooperation adjust plough tilling depth it is impossible to Plough point is run into situation about layinging of markstone and makes emergency processing, often result in plough point and damage.
