Description
Technical field
The utility model belongs to agricultural mechanical field, relates to a kind of workpiece of grass root cutter of the grassland degeneration caused because of herbage perennation for rejuvenation, is specifically related to one and back and forth cuts root rejuvenation special saw Shi Qiegen cutter.
Background technology
Natural and meadow that is artificial planting is mostly herbage for many years, occurs that herbage root is degenerated after growing several years, and soil occurs hardening and physicochemical property and water-holding capacity decline, and grass industry is impaired, and the atrophy of severe patient herbage is withered and yellow.Existing existing rejuvenation herbage mode of loosening the soil all has stirred upper layer of soil, occurs soil bareness, accelerates grassland degeneration, desertification; Also disturbance grass roots, hinders the growth of herbage, reduces forage yield and quality.The method that research finds to adopt mechanization to break ground cuts root realizes low disturbance, without turning over upturned soil, locally loosening, recovers soil structure, cuts off side root, makes herbage rejuvenation, promotes that herbage growth is bred.
In existing associated cutter, lawn injury-root rejuvenation cutter is only applicable to lawn soil, and limitation is large.(number of patent application: 200720149419.9) complete by High Rotation Speed the course of work of being completely cured of breaking ground, its soil-entering resistance is comparatively large, has stronger soil disturbance to coil the tooth-like cutter that breaks ground.Multifunctional dot, bar formula vertical cut cutter have the feature that structure is simple, ability of burying is strong and working resistance is little, but exist to bury and cut root difficulty, cut root poor performance and the excellent not problem of working effect.Cutting knife and the loose soil of high efficiency lawn improving machine are fixed in " V " type frame, and many group cutting knifes are symmetrically arranged amongst on the both wings of this " V " type frame, complex structure, impracticable.2SB-2.1 type (cutting root) loosen the soil after culture machine cut root part chisel point and single-blade type plough shovel can exchange, root can be cut to the Leymus Chinensis Steppe of typical degradation to loosen the soil improvement, though it does not overturn upturned soil, just can loosen and herd sod layer soils, destroy meadow epidermis comparatively serious.When these cutters normally work, carry out cutting root though can scratch turf, destroy comparatively large to natural vegetation, it is undesirable to cut root effect.
Breaking ground and cutting root operation is a kind of low disturbance without the grassland soil structure repair mechanized farming method of turning over the not sand of turning up soil, in order to realize scratching top layer knotts clay skin and cutting off herbage root system, meadow formed thin narrow joint-cutting and loosens with local, seldom primary planting being damaged.Research and develop one according to this Theories and methods back and forth cuts root rejuvenation special saw Shi Qiegen cutter to the utility model people exactly.
Utility model content
The purpose of this utility model overcomes existing breaking ground to cut the deficiency of root effect cutter for same, one is provided back and forth to cut root rejuvenation special saw Shi Qiegen cutter, it has low disturbance without turning over the not sand of turning up soil, slight damage turf, feature that tillage resistance is little, what can realize natural or artificial degeneration herbage preferably cuts root rejuvenation, and this cutter can be arranged on hydraulic saw type forage grass root cutter and use.
For achieving the above object, the technical solution adopted in the utility model is as follows:
One back and forth cuts root rejuvenation special saw Shi Qiegen cutter, comprise a cutter hub, this cutter hub comprises handle of a knife and blade, its special character is, the top of described handle of a knife is with blade center line for reference symmetry is provided with two row's installing holes, and described blade is straight knife, the side of described blade arranges blade, blade arranges knife saw tooth in the side that blade is relative, and described knife saw tooth is vertical working On The Sawteeth Shape, and described blade is double-sided blade.
Further, the tooth pitch t of described knife saw tooth is 15-20mm, tooth depth h is within the scope of 10-15mm, and cutting angle δ is 15 °-45 °, and angle of wedge β is 10 °-40 °.
Further, the cross section of described cutter hub is shuttle-type, and cutter hub length is 650-850mm, and thickness is 5-7mm, and width is 120-180mm.
Further, the point of a knife angle of described cutter hub is 20 °-45 °.
Further, the length of described handle of a knife is 200mm.
Further, the diameter of described installing hole is 8-12mm.
Further, described cutter hub adopts 65Mn spring steel to make.
What the utility model provided back and forth cuts root rejuvenation special saw Shi Qiegen cutter, can effective sawing radical operators, cut off herbage within the scope of 100-250mm soil layer horizontal walk rhizome, and it is little to the disturbance of grass roots, cutter makes simple, it is convenient to change, penetration performance, sliding cutting is functional, effectively can reduce energy ezpenditure during facility work, raise the efficiency, reduce the requirement to tractor power, it can realize width of slit and be not more than 8mm, the utility model is produced realizing grass root cutter toolization, improve grassland integrated production capacity, realize environmental protection and livestock breeding benign development is significant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the broached-tooth design schematic diagram of knife saw tooth 5 in Fig. 1.
Wherein, 1, handle of a knife, 2, blade, 3, installing hole, 4, blade, 5, knife saw tooth.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
See Fig. 1, the utility model embodiment back and forth cut root rejuvenation special saw Shi Qiegen cutter, comprise a cutter hub, this cutter hub comprises handle of a knife 1 and blade 2, the top of handle of a knife 2 with blade center line for reference symmetry is provided with two row's installing holes 3, blade 2 is straight knife, and the side of blade 2 arranges blade 4, and blade 2 arranges knife saw tooth 5 in the side that blade 4 is relative, knife saw tooth 5 is vertical working On The Sawteeth Shape, knife saw tooth 5 uses as main work cutting edge, and blade 4 is double-sided blade, and the line of demarcation of blade 2 and blade 4 is streamlined.
In fig. 2, knife saw tooth 5 is designed to vertical working On The Sawteeth Shape, and the tooth pitch t of knife saw tooth 5 is 15-20mm, tooth depth h is within the scope of 10-15mm, and cutting angle δ is 15 °-45 °, and angle of wedge β is 10 °-40 ° sawtooth side lines is straight line or curve.
The cross section of cutter hub is shuttle-type, and successively decrease to blade 4 edge and knife saw tooth 5 edge thickness along camber line in the blade center of cutter hub, cutter hub length is 650-850mm, and integral thickness is 5-7mm, and width is 120-180mm.
