Description
Technical field
The invention belongs to agricultural machinery technological field, be specifically related to a kind of agricultural machinery cultivating member of compacting soil--have the elasticity soil press wheel of double cavity structure.
Background technology
Press wheel is a kind of agricultural machinery parts commonly used; its major function is that soil is after planting suppressed, and with density and the consolidation of increase soil, thereby it is too fast to prevent that soil moisture runs off; soil protection soil moisture content, maintenance ground temperature are seed sprouting and the suitable kind bed environment of creation of emerging.
The suppression of soil wheel is applied to can realize on sower earthing, two operation functions of suppression, can make the structure of sower more compact.Existing suppression of soil wheel mainly contains concave surface press wheel, the compound press wheel of circular cone, two narrow V-type press wheel etc. of taking turns is several.
The compound press wheel of concave surface press wheel and circular cone is all to utilize its wheel rim profile to the centre, the effect of gathering to be arranged to kind of ditch both sides soil, thereby realizes earthing, suppression operation.But its wheel rim outer shape can only be fit to soil comparatively soft, that viscosity is little for what fix.On the contrary, two narrow V-type press wheels of taking turns are because its tire is narrower, and are long-pending less with soil contact, easily are absorbed in soil, so be not suitable for mellow soil.
When contacting with ground, contact-making surface produces crimp due to the rubber-like wheel body, can make wheel body produce radial load and side force, so that its bottom is expanded to both sides.Improvement through to the wheel body profile can make the press wheel wheel body in the actual job process, and the direction of the suffered bonding force in sidewall reaches consistent with the force direction of the required earthing power of seeding operation.This phenomenon provides theoretical foundation for the adjustment of design earth pack wheel surface structure and soil contact action power.
Natural rubber has higher at normal temperatures elasticity because of it, good mechanical strength, and hysteresis loss is little, and when repeatedly being out of shape, living heat is low, and its flexible resistance is high in addition, and this provides theoretical foundation for material that agricultural machinery adopts.
Above existing theoretical foundation and practical experience, all the realization for press wheel earthing and suppression function provides a kind of scheme of feasibility.
Summary of the invention
