Description
Technical field
The utility model relates to rotary cultivator tool cutter, specifically, relates to horizontal shaft type rotary cultivator tool cutter, belongs to technical field of agricultural machinery.
Background technology
The driving soil cultivating machine of rotovator to be a kind of with rotary cutter be workpiece, also known as rotary plow, because of its have hack ability strong, plough after the features such as earth's surface is smooth, be widely used in novel agricultural field.In addition, rotovator also possesses the function of chopping earth's surface following crop root stubble, and can be later stage sower provides and well plant bed, is conducive to high-efficient homework.
Rotovator can be divided into horizontal shaft type and vertical shaft type two class by its tool assembly mode, wherein more with the horizontal shaft type rotovator application that cutter shaft level is horizontal again.Horizontal shaft type rotovator is when operation, and its cutter cuts soil layer by after forward direction, and is kicked up rearwardly and upwardly by soil block, throw on case and planker, make it further fragmentation, there is stronger hack ability, one-stop operation can make soil in small, broken bits, evenly, Land leveling, reaches the requirement that nonirrigated farmland is sowed or paddy field is planted in clay fertilizer blending, be conducive to striving for farming season, improve work efficiency, greatly save manpower and materials, improve economic benefit.
But, it should be noted that, rotary cultivator tool cutter is as the workpiece of most critical on rotovator, and the scientific rationality in himself intensity, rigidity, wearability, reliability, service life and design determines combination property and the economic benefit of rotovator to a certain extent.Rotary cultivator tool cutter mostly in the market is scalpriform cutter and tulwar.Scalpriform cutter front end is narrower, there is ability of burying preferably, energy ezpenditure is little, but in the course of work, the curved groove part of cutter very easily twines grass, easily occurs rotary tool axis retardance stall phenomenon, motor dry combustion method is caused to generate heat, affect motor service life, directly may cause burn-down of electric motor what is more, cause economic loss to peasant household, therefore this kind of cutter is used for the shallow and few vegetable garden of weeds and garden, does not possess generalization widely.Compared to flute profile cutter, the curved cutting edge of tulwar has Sliding cutting action, weeds root can be cut off in the course of the work easily and straw winding, but because the cutting edge place of tulwar is through polishing processing, causing its skiving material at blade place while possessing sharpness, weakening its rigidity to a certain extent, once run into dryness compared with hard place matter or the stone under being imbedded in earth's surface, just be easy to cause cutter bending even to rupture, have a strong impact on cutting-tool's used life.In addition, blade place also easily with bury stone generation heavy wear or shock in soil, cause blade place tipping, affect its Sharpness, and then occur the phenomenon of cutting continuous weeds, bury and twine careless hidden danger.No matter this hidden danger is all cause certain economic loss to consumer or producer, has hit the confidence of consumer to a certain extent, has been unfavorable for the sound development of industry.Therefore, have the ability of breaking ground concurrently urgently to release by force, without twining the rational horizontal shaft type rotary cultivator tool cutter of careless hidden danger, long service life and design science.
