Embodiment Construction

[0012] The specific content and implementation of the present invention will be further described below with reference to the embodiments shown in the drawings.

[0013] The exponential function type bionic drag reduction subsoiling shovel handle involved in the present invention is mainly composed of a fastening part H1 section (fastened connection with the frame) and a curved soil cutting section H2 (shearing damage to the soil and assisting subsequent soil crushing) It is composed of three parts, H3 (installation of deep loose blade). According to the general subsoil shovel handle design requirements, H1+H2+H3=600mm (according to the actual subsoil requirements, the value can be increased appropriately), where the length of H2+H3 section is 362mm, and the length of H1 section is 238mm , Width W is 60mm (according to JB / T9788-1999 standard), thickness T is 25mm (according to JB / T9788-1999 standard). The H3 section is the installation section for installing the deep loose blade...

Abstract

The invention relates to a sub-soiling shovel, i.e. a typical soil working part of agricultural machinery, in particular to an exponential function curve type biomimetic resistance-reducing sub-soiling shovel handle with a biomimetic structure, aiming at solving the technical problems of excessive working resistance of the traditional sub-soiling shovel. The sub-soiling shovel handle is based on outlines of the upper surfaces of claw toes of a mus musculus and in the shape of an exponential function curve mode. The technical scheme of the invention is that the front-surface cutting edge of the biomimetic resistance-reducing sub-soiling shovel handle, which cuts soil, is in the shape of a longitudinal outline (in the exponential function curve mode) of the upper surface of a middle toe of a front claw of the mus musculus; and an exponential function equation is as follows: y=-66.61e<0.0117x> +17.78e<-0.1835x>, wherein x is more than or equal to -2 and less than and equal to 40, and x is more than or equal to -0.04 and less than and equal to 0.8 mm in terms of mm. A wedge angle alpha of the biomimetic resistance-reducing sub-soiling shovel is more than or equal to 15 degrees and less than or equal to 25 degrees. According to the biomimetic resistance-reducing sub-soiling shovel handle with exponential function characteristics, the working resistance of the sub-soiling shovel canbe reduced by 15 percent.

Description

Technical field: [0001] The invention relates to a bionic drag-reducing deep loosening shovel, in particular to an exponential function type bionic drag-reducing deep loosening shovel handle with drag reducing effect. Background technique: [0002] At present, with the development of modern agricultural technology in the direction of energy saving, consumption reduction, sustainability, and environmental protection, the operation quality and requirements of agricultural farming machinery are also continuously improved, especially for various typical soil working parts. Requirements. The subsoil shovel is a typical soil plowing part of agricultural machinery, and the excessive working resistance of the traditional subsoil shovel has been a problem that people have long been concerned about. The working resistance of the subsoil shovel mainly comes from two aspects: one is the friction resistance between the subsoil shovel and the soil; the other is the shear resistance of the sub...
