Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
As shown in figure 1, the invention provides the secondary formula deep soil loosing shovel that breaks ground of one kind, including spade 110, resistance to sharpening 120 and
Spear protective case 130.
Fig. 2, the straight handle section 111 on the top of spade 110 and the bending active section 112 of bottom are referred in the lump.The staight shank
Section 111 is vertically attached on subsoiler.Bending active section 112 is extended downwardly and inwardly until spear 113.The depth that i.e. present invention is provided
Pine shovel is compared with conventional deep soil loosing shovel, and spade is formed in one with shovel body, spear, can make deep soil loosing shovel integrally with higher strong
Degree, increases service life.
Fig. 3 is referred in the lump, and the resistance to sharpening 120 is fixed to the inner side of bending active section 112, institute by bearing pin 114,115
Stating includes the cutting edge connecting portion 123 of preceding cutting edge 121, rear cutting edge 122 and the preceding cutting edge 121 of connection and rear cutting edge 122.It is described wear-resisting
Sword 120 is made using high-abrasive material, it is possible to increase deep soil loosing shovel soil cutting effect, improves Subsoiler efficiency, and increase deep soil loosing shovel is wear-resisting
Property and service life.Resistance to sharpening 120 can be changed at any time simultaneously, can greatly save cost.
As shown in figure 4, spear fixing groove 131 is provided with the bottom surface of the spear protective case 130, the spear fixing groove
131 coordinate with spear 113, spear protective case 130 is linked on spear 113, and are protected spear using bearing pin 116,117
Sheath 130 is fixed with spear 113.By setting spear protective case 130, the protection to spear is realized, is protected by spear
Sheath 130 replaces traditional spear to be operated.Simultaneously traditional changeable type spear, generally spear pass through bearing pin with shovel body
Fixed, active force is fully fallen on bearing pin during work, easily causes the fracture of bearing pin.Due to the spear protective case 130 of the present invention
It is linked on spear 113, also just increases the intensity of spear 113.Spear protective case 130 can be changed at any time again, can be saved significantly
Cost-saving.
In another embodiment, the secondary sword 132 that breaks ground is provided with the spear protective case working face, it is described secondary
The soldering of sword 132 break ground on spear protective case 130.The secondary sword 132 that breaks ground is triangular in shape, due to the secondary sword 132 that breaks ground
Setting makes the edge of shovel move forward, and increases secondary function of breaking ground, and improves soil and breaks ground effect, improves operating efficiency, reduce energy consumption, save energy
Source.
As shown in figure 5, angle α is 18 °~22 ° between working face and horizontal plane on the spear protective case 130, it is secondary broken
Angle β is the contour line of cutting edge 121 and plummet face before 63 °~67 °, resistance to sharpening 120 between the anterior sword line of native sword 132 and horizontal plane
Between angle γ be 9 °~11 °.
As Figure 6-9, in another embodiment, the equation of the bending active section 112 inner side contour curve OA is：
y1=0.0000004x4-0.00015x3+0.01671x2-0.09505x。
The equation of the bending active section 112 lateral profile curve OB is：
y2=0.0000002x4-0.00008x3+0.01277x2-0.49086x。
The equation of the curve MN of 120 connecting portion of resistance to sharpening 123 is：
Pass through the setting of the present invention, by increasing capacitance it is possible to increase secondary function of breaking ground, improve soil and break ground effect, improve operating efficiency,
Energy consumption is reduced, the energy is saved.So that certain breaks ground experiment as an example, soil parameters is as shown in table 1, the secondary formula of breaking ground that the present invention is provided
Deep soil loosing shovel loosens the soil experimental data as shown in table 2, and conventional deep soil loosing shovel experimental data of loosening the soil is as shown in table 3.
Table 1
Table 2
Table 3
Understood according to table 2, the contrast of table 3, under identical working depth, identical operating rate, offer of the invention
The secondary formula deep soil loosing shovel that breaks ground effect of loosening the soil is substantially good with conventional deep soil loosing shovel, is embodied in secondary formula deep soil loosing shovel pine of breaking ground
Working resistance is smaller, and working resistance reduces more than 8% compared with conventional deep soil loosing shovel.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
