Description

A kind of secondary formula deep soil loosing shovel that breaks ground
Technical field
The present invention relates to agro-farming field of mechanical technique, particularly a kind of secondary formula deep soil loosing shovel that breaks ground.
Background technology
The reality such as the deterioration of the ecological environment facing along with enhancing and the countries in the world of people's ecological environment consciousness are pressedPower, protective farming technique arises at the historic moment as a novel farming technique. Subsoiling technology is as protectivenessOne of four technology of farming more and more come into one's own. Subsoiling can be improved cultivated soil layer soil texture, activation ploughBottom, improves soil water storage and crop drought resistance, lodging tolerance, reduces environmental pollution, increases cropsOutput, realize agricultural sustainable development. Therefore develop Multifunction subsoiler and subsoiling componentIt is the task of top priority of subsoiling Technique Popularizing. Deep soil loosing shovel, as the vitals of subsoiler, is representing subsoiling skillThe level of art.
The shape of deep soil loosing shovel affects many factors, as tractive resistance size, operating speed, the subsoiling degree of depth,Operation quality etc. It forms by shoveling head and shoveling post two parts. Shovel head is the critical component of deep soil loosing shovel. ConventionalShovel capitiform formula have scalpriform shovel, duck's foot shovel, double-vane shovel etc. The width of scalpriform shovel is narrower, and shovel post widthClose, its shape has plane and breakover shape. Breakover shape hack better performances, and there is certain diggingEffect; The working resistance of plane is less, simple in structure, and intensity is high, easy to make, after wearing and tearing, is easy toChanging, be both applicable to subsoiling in the ranks, be also applicable to deep loosen, is most widely used a kind of deep soil loosing shovel.Duck's foot shovel and double-vane shovel shovel head are larger, and this class shovel head is mainly used in subsoiling in the ranks. Double-vane shovel is more usually used in pointWhen layer depth pine, subsoiling topsoil, in the time that resistance of soil is lower, also can be used for subsoiling deep soil.
Summary of the invention
The present invention has designed and developed a kind of secondary formula deep soil loosing shovel that breaks ground, and has overcome prior art deep soil loosing shovel spearDefect easy to wear, the function that uses changeable type spear protective sleeve to realize spear is protected spear simultaneouslyProtect, improved the service life of deep soil loosing shovel.
Technical scheme provided by the invention is:

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art's referenceDescription word can be implemented according to this.
As shown in Figure 1, the invention provides a kind of secondary formula deep soil loosing shovel that breaks ground, comprise spade 110, resistance toSharpening 120 and spear protective sleeve 130.
Consult in the lump Fig. 2, the straight handle section 111 on described spade 110 tops and the bending active section 112 of bottom.Described straight handle section 111 is vertically installed on subsoiler. Bending active section 112 extends internally downwards until shovelPoint 113. Be deep soil loosing shovel provided by the invention compared with conventional deep soil loosing shovel, spade with shovel body, spear isOne-body molded, can make deep soil loosing shovel entirety there is higher intensity, increase service life.
Consult in the lump Fig. 3, described wear-resisting sword 120 is fixed to bending active section 112 by bearing pin 114,115Inner side, described in comprise front cutting edge 121, rear cutting edge 122 and connect front cutting edge 121 and rear cutting edge 122Cutting edge connecting portion 123. Described wear-resisting sword 120 uses high-abrasive material to make, and can improve deep soil loosing shovel and cutSoil effect, improves Subsoiler efficiency, increases deep soil loosing shovel wearability and service life. Wear-resisting sword 120 simultaneouslyCan change at any time, can greatly save cost.
As shown in Figure 4, on the bottom surface of described spear protective sleeve 130, be provided with spear holddown groove 131, instituteState spear holddown groove 131 and coordinate with spear 113, make spear protective sleeve 130 can be linked in spear 113Upper, and use bearing pin 116,117 that spear protective sleeve 130 and spear 113 are fixed. By arrangingSpear protective sleeve 130, has realized the protection to spear, replaces tradition shovel by spear protective sleeve 130Point carries out work. Simultaneously traditional changeable type spear, is generally spear and fixes by bearing pin with shovel body,When work, active force all drops on bearing pin, easily causes the fracture of bearing pin. Because spear of the present invention is protectedSheath 130 is linked on spear 113, has also just increased the intensity of spear 113. Spear protective sleeve 130Can change at any time again, can greatly save cost.
In another embodiment, on described spear protective sleeve working face, be provided with the secondary sword 132 that breaks ground,Described secondary breaks ground sword 132 seam on spear protective sleeve 130. The described secondary sword 132 that breaks ground is triangleShape, because the break ground setting of sword 132 of secondary makes edge of shovel reach, increases the secondary function of breaking ground, and improves soilThe effect of breaking ground, improves operating efficiency, reduces energy consumption, saves the energy.
As shown in Figure 5, on described spear protective sleeve 130 between working face and horizontal plane angle α be 18 °～22 °, the secondary angle β between the anterior sword line of sword 132 and horizontal plane that breaks ground is 63 °～67 °, wear-resisting swordBetween the outline line of 120 front cutting edges 121 and plummet face, angle γ is 9 °～11 °.
As Figure 6-9, in another embodiment, described bending active section 112 inner side contour curve OAEquation be:
y1＝0.0000004x4-0.00015x3+0.01671x2-0.09505x。
The equation of described bending active section 112 lateral profile curve OB is:
y2＝0.0000002x4-0.00008x3+0.01277x2-0.49086x。
The equation of described wear-resisting sword 120 connecting portion 123 curve M N is:
y 3 = 0.00134 x 3 - 0.10609 x 2 + 3.6407 x , x ∈ [ 0 , 26.2 ] 22.668 e 0.0258 x , x ∈ ( 26.2 , 93 ] .
By setting of the present invention, can increase the secondary function of breaking ground, improve the soil effect of breaking ground, improveOperating efficiency, reduces energy consumption, saves the energy. Taking certain experiment of breaking ground as example, soil parameters is as table 1Show, the secondary provided by the invention formula deep soil loosing shovel experimental data of loosening the soil of breaking ground is as shown in table 2, conventional deep soil loosing shovelThe experimental data of loosening the soil is as shown in table 3.
Table 1
Table 2
Table 3
Contrast according to table 2, table 3 known, in identical working depth, under identical operating rate, thisThe secondary providing of invention break ground formula deep soil loosing shovel loosen the soil effect will be obviously good and conventional deep soil loosing shovel, concrete bodyNow the break ground working resistance of formula deep soil loosing shovel pine of secondary is less, and working resistance reduces compared with conventional deep soil loosing shovelMore than 8%.
Although embodiment of the present invention are open as above, it is not restricted to description and enforcement sideListed utilization in formula, it can be applied to various applicable the field of the invention completely, for being familiar with abilityThe personnel in territory, can easily realize other amendment, therefore do not deviate from claim and etc. homotypeEnclose under limited universal, the present invention is not limited to specific details and illustrates here and the figure describingExample.
