Problems solved by technology

However, due to adhesion and other reasons during the tillage process, the work resistance is large and the soil disturbance is large. Therefore, optimizing the structure of the opener, reducing tillage adhesion, and reducing soil resistance are of great significance for improving the quality of trenching and reducing energy consumption.
[0003] The discs of ordinary double-disc openers are flat. When in contact with the soil, the capillary force and viscous force caused by the continuous water ring or water film on the contact interface will cause adhesion, which will increase the disturbance of the soil. Reduce the quality of ditching, affect the yield of crops, and at the same time cause an increase in traction resistance to a certain extent

Embodiment Construction

[0015] specific implementation plan

[0016] Such as figure 1 As shown, in this embodiment, wedge-shaped protrusions 2 and spherical convex hulls 3 are arranged on the surface of disc 1 of the double-disc opener. The embodiment has three layers in total, and the wedge-shaped protrusion 2 of the adjacent layer is opposite to the spherical convex hull 3; T is the thickness of the disc 1; as figure 2 , image 3 and Figure 4 As shown, H1 is the height of the wedge-shaped protrusion 2, and L1 is the length of the wedge-shaped protrusion 2: as Figure 5 As shown, H2 is the height of the spherical crown of the spherical convex hull 3, D2 is the diameter of the spherical crown of the spherical convex hull 3; A is the angle between a wedge-shaped protrusion 2 and a spherical convex hull 3 adjacent on the same ring along the radial direction ; Wherein H1=T, L1=D2, H2=7%~13%D2, A=7.2°~12°.

Abstract

The invention discloses a coupled bionic disc structure of a double-disc ditcher, which is characterized in that wedge-shaped bulges and spherical convex hulls are formed on the disc surface of the double-disc ditcher, the wedge-shaped bulges and the spherical convex hulls are annularly distributed at intervals in multiple layers, and the wedge-shaped bulges and the spherical convex hulls of the adjacent layers are opposite to each other. In the ditching process of the ditcher, the wedge-shaped bulge and spherical convex hull coupled bionic structure can break the continuity of a water film formed when the disc surface contacts soil, reduce the adhesion of soil so as to reduce the adhesion of soil to discs, reduce the resistance of soil to the ditcher, improve the ditching quality and reduce the consumption of fuel.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, relates to a general double-disc opener, in particular to a double-disc opener coupling bionic disc structure. Background technique [0002] Double-disc openers are widely used in the soil-contacting parts of grain seeders and row crop precision seeders, and are suitable for high-speed operations with poor soil preparation conditions and high soil humidity. However, due to adhesion and other reasons during the tillage process, the work resistance is large and the soil disturbance is large. Therefore, optimizing the structure of the opener, reducing tillage adhesion, and reducing soil resistance are of great significance for improving the quality of trenching and reducing energy consumption. . [0003] The discs of ordinary double-disc openers are flat. When in contact with the soil, the capillary force and viscous force caused by the continuous water ring or water film on the contact interf...
