Abstract
The invention relates to a bionic core moldboard type sowing boot which belongs to the technical field of agricultural machinery. The bionic core moldboard type sowing boot is based on the scale surface structure and the bulge-shaped structure of a soil cave animal pangolin, has the characteristics of abrasion resistance, visbreaking and drag reduction and is determined according to optimized analysis and geometric measurement. The scale-shaped geometric structure and the bulge-shaped geometric structure are regularly distributed on the upper surface of the front base body of a core moldboard; the center distance L between the scale-shaped geometric structure and the bulge-shaped geometric structure is 5-25 millimeters; and the scale-shaped geometric structure, the bulge-shaped geometric structure and the base body are processed into an integer. The bionic core moldboard type sowing boot disclosed by the invention has good technical effect of reducing the soil adhesion and the working resistance and can enhance the sowing and fertilizing quality and reduce the power consumption.
Description
Technical field
The invention belongs to agricultural machinery technological field, be specifically related to a kind of bionical core share type seed opener.
Background technology
In farming operation, all need to form a ditch, to carry out sowing and applying fertilizer on surface, soil.The ditch shape that agricultural production requires seed opener to output is neat, and the depth is consistent, and sowing evenly.But seed opener is under different soil regime, and the ditch formed has very big difference.When it works in the soil that humidity is larger, soil adhesion, at its working surface, causes tractive resistance to increase, and the ditch shape outputed is irregular, deep mixed in ditch of seed is caused, have impact on seeding quality.Therefore reducing adhesion resistance is the major issue that seed opener should solve.
Summary of the invention
Order of the present invention solves problem, the scale surface texture providing a kind of surface to have soil burrowing animal pangolin and the ploughs of convex closure type structure such as existing sowing and ditching parts clay, resistance increase.Its adopts touches native surface design at common core share type seed opener and goes out Palta type structure and convex closure type structure is formed, and these two kinds of biomimetic features make it have the function alleviating soil adhesion and reduce working resistance.
The present invention is by core ploughshare 1, ploughshare handle 2, wing plate 3, connecting plate 4, grain tube 5 and to protect kind cover 6 and form, it is characterized in that the upper surface rule of core ploughshare 1 forward base 9 is distributed with Palta type geometry 7 and convex closure type geometry 8, both Palta type geometry 7 and convex closure type geometry 8 centre-to-centre spacing L is 5 ~ 25mm.
The present invention has wear-resisting, visbreaking based on the scale surface texture of soil burrowing animal pangolin and convex closure type structure, falls the feature of resistance, according to Optimization analyses and dimensional measurement determined.
