Abstract

The utility model relates to a turbine disk blade, which comprises an assembly area for being connected with a power device and a working area for breaking the soil. The turbine disk blade is characterized in that the working area is a circular disk surface formed by harrow teeth. The harrow teeth are equipped with cutting edges. The edge lines of the harrow teeth are vortex-shaped lines diffusing outwardly and uniformly from the center of the disk blade. The cross section of the working area of the disk blade is uniformly corrugated. When entering the soil, the turbine disk blade is at an angle of close to 90 degrees with respect to the soil surface. Therefore, only a minimum force is required for the turbine disk blade to enter the soil and the power consumption is also lowest. Meanwhile, the disturbance and the destroy to the soil are also reduced so as to realize the purpose of protective cultivation.

Description

The turbine disc blade

Technical field

The utility model relates to a kind of disc that uses on agricultural soil preparation machine and the no-tillage seeding machine, specifically refers to a kind of turbine disc blade.

Background technology

Conventional tillage technology such as a kind of farm tools suppression are ploughed and harrowed to the most of long-term mouldboard plow that adopts of ploughing of northern China, and this traditional mouldboard plow is turned over makes that the farmland is exposed, water and soil loss and wind erosion are desertified, and not only causes soil fertility to descend, and nibbles soil capable of using.Therefore, country advocates the conservation tillage mode, breaking on without the soil of ploughing, cuts soil, loosens the soil etc.Often be plane disc blade, cutaway disk blade and all kinds of ripple disc at China's power-actuated breaking instrument that do not need commonly used at present.Plane disc blade (Fig. 1) is cut soil better, but plane disc blade round edge is too narrow, and its area that buries is narrower, and is little to the disturbance of soil, and the performance of loosening the soil is bad.Ripple disc (Fig. 2) can be cut the band that loosens the soil of extruding broad, but the increase of the required power of burying, operation under the condition of heavy soil does not suit.To above problem, this just needs us that existing breaking disk is improved.Develop a kind of novel disc, make it when cutting the band that loosens the soil of extruding broad, reduce the required power that buries as much as possible.

The utility model content

The utility model aim to provide a kind of required power that buries little, can cut the band that loosens the soil of extruding broad, the turbine disc blade little to the disturbance of soil layer; In order to realize above-mentioned technique effect; The technical scheme of the utility model is: the turbine disc blade; Comprise and be used for assembly section that is connected with power set and the workspace that is used to break ground; The circular card that the workspace of said disc is made up of rake teeth, said rake teeth has cutting edge, and the crest line of rake teeth is the vortex-like line that outwards evenly spreads from the center of circle of disc; The cross section of the workspace of said disc is uniform corrugated.

The beneficial effect of the utility model is: the turbine disc blade is assemblied on agricultural soil preparation machine or the no-tillage seeding machine, because the cross section of the workspace of turbine disc blade is corrugated, and when blade buries, the band broad that loosens the soil that cuts out.Because agricultural soil preparation machine or no-tillage seeding machine are walked forward, drive blade and rotate along assembled shaft, when the moment that blade breaks ground, the break ground direction of power of blade is perpendicular to the ground.Like this, the required power of breaking ground is less, improves the operating efficiency of blade, and is little to the disturbance of soil layer simultaneously, reduces water and soil loss, plays the purpose of conservation tillage.

For characteristic and the technology contents of further understanding the utility model, see also following detailed description and accompanying drawing about the utility model, however appended graphic reference and the explanation usefulness of only providing, not as restriction to the utility model.

Embodiment

Embodiment 1

As shown in Figure 3, present embodiment provides a kind of turbine disc blade 3, and the turbine disc blade comprises two parts, is respectively the assembly section 32 of disc inner circle and the workspace 33 at cylindrical place.Disc is assemblied on the assembled shaft of agricultural soil preparation machine or no-tillage seeding machine and uses, disc can rotate along assembled shaft when burying work.The workspace of disc is made up of 60 rake teeths, is interconnected between each rake teeth, makes the card of workspace be wavy, and the crest line 31 of wave is from the disc center of circle, the vortex-like line that outwards evenly spreads.The quantity that should be pointed out that rake teeth can be confirmed according to the hardness in soil and the degree of depth in needs farming soil, can be the arbitrary number between the 50-80.As shown in Figure 4, the cross section of the workspace of turbine disc blade is undulatory, and the outer circumferential edges of whole turbine disc blade has certain width, can form the crowded band of cutting of certain width after burying.

Fig. 2 is existing common ripple disc 2, and the ripple crest line 21 of common ripple disc 2 is disk RADIALs, and common ripple disc is breaking ground in an instant, and the ripple crest line becomes certain acute angle with ground, and the required power of burying is bigger.And the turbine disc blade in the present embodiment is as shown in Figure 3, and the ripple that its outer circular edge forms approaches 90 degree with the angle on ground 4 when burying, and its breaking, to cut the required moment of soil just minimum, and little to the disturbance of soil layer, is not easy to destroy the topsoil structure.

Should be noted that: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; For a person skilled in the art; Still can make amendment, perhaps part technical characterictic wherein is equal to replacement the technical scheme that aforementioned each embodiment put down in writing.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.

Claims
