Problems solved by technology

However, none of these studies can fundamentally change the high wear condition of the subloose cutting edge, and can only prolong its service life in a short period of time, but at the same time greatly increase the manufacturing cost and use cost
At the same time, there has also been a waste of high-quality, expensive materials used in ordinary working conditions

[0037] Example 1 Refer to Figure 1a, Figure 2a, Figure 2b, Figure 2c:

[0038] Fig. 1a and Fig. 2a are the structural diagram and size diagram of the regularly distributed pack-shaped bionic subsoiler blades, and Fig. 2b and Fig. 2c are the dimension diagrams of the cross-distributed and randomly distributed pack-shaped subsoiler blades. The sliding speed of the soil on the surface of the subsoiler blade is 1.94m / s, the size of the soil particles is 0.214-0.420mm, and the direction of the impact velocity of the soil is at an angle of 35° to the surface of the blade. According to the above conditions and considering the size of the deep loose cutting edge, the height of the envelope is determined to be 2 mm, the radius of the ball where the envelope is located is 5 mm, and the ratio of the height of the envelope to the diameter of the bottom circle is 2:8. Therefore, the contour equation of the envelope is obtained for: x 2 +y 2 +z 2 =5 2 , where, 4mm≤x≤5mm, 4mm≤y≤5mm, 3mm≤...

Abstract

The invention relates to a bionic wear-resisting deep-digging shovel blade, which comprises two bionic wear-resisting structural forms, i.e. a rib form and a lug form. The bionic wear-resisting deep-digging shovel blade is based on the characteristic of a geometry structure on the shell surface of aquatic mollusk which can resist the abrasion of grinding materials. The bionic wear-resisting ribbed structural shape is that: y=asin(bx+c), wherein a indicates amplitude, b indicates frequency, c indicates an initial phase position, a is more than 0 and is less than or equal to 10mm, bx minus c is more than or equal to 0 and is less than or equal to pi, and x is more than or equal to 0 and is less than or equal to 20mm, and the distance between two adjacent ribs is that: L is more than 0 and is less than or equal to 50mm; and the lug bionic wear-resisting structure is characterized in that a contour of the lug bionic wear-resisting structure is a spherical-crown shape: x<2>+y<2>+z<2>=r<2>, wherein x is more than or equal to 0 and is less than or equal to 10mm, y is more than or equal to 0 and is less than or equal to 10mm, z is more than or equal to 0 and is less than or equal to 10mm, r is more than or equal to 0 and is less than or equal to 12mm, and a distance L between every two lugs is that: L is more than 0 and is less than or equal to 50mm. The ribbed structure and the lug structure are suitable for different deep-digging shovel blades of different forms. The wear resistance of the bionic wear-resisting deep-digging shovel blade is improved by 50 percent compared with that of a traditional shovel blade with a smooth surface.

Description

Technical field: [0001] The invention relates to a bionic wear-resistant deep loosening blade, in particular to a bionic wear-resistant sub-loosening blade with two bionic wear-resistant geometric structures of a ribbed shape and a bag shape. These two bionic wear-resistant geometries can be applied to subsoiler blades with a variety of top surfaces in contact with the soil, including chisel, duck-foot and double wing shapes. technical background: [0002] Soil subsoiling is a soil cultivation method developed with the need for conservation tillage techniques such as low-tillage and no-tillage to replace traditional tillage-ploughing. The core working part of this tillage method is the subsoiling shovel. However, during the tillage process, the wear of the subsoiler blade, especially the subsoiler blade, is the most serious. The wear caused by the contact between the soil and the subsoiler blade is abrasive wear, which is one of the main forms of failure of the subsoiler bla...
