Bionic sand-crossing walking wheel

Abstract

The invention discloses a bionic sand-crossing walking wheel. The bionic sand-crossing walking wheel consists of a plurality of wheel legs and a hub, wherein each wheel leg comprises a moving bottom plate, a fixed bottom plate and wheel stabs. The effects of limiting the flow, fixing the sand under the wheel and effectively preventing the wheel from sinking and sliding are achieved through the enlightenment is obtained according to the structure and the shape as well as the sand touching mode of the toe of the Affrican ostrich with excellent sandy-land passability, and by ingenious mutual matching of the moving bottom plates and the fixed bottom plates of the wheel legs; simultaneously the wheel stabs are controlled to stab into the sand under the wheel so as to play a role in increasing the traction and adhesion force; when the bionic sand-crossing walking wheel is separated from the sand and crosses forwards, the moving bottom plates of the wheel legs form backward pedaling to the compacted sandpile under the wheel under the action of the reaction force of the spring, so that the traction force of hooks is further increased, and at the moment, due to returning of the moving bottom plates and the retraction of the wheel stabs of the wheel legs, the disturbance to the sand is reduced when the wheel crosses forwards; and simultaneously, by retraction of the wheel stabs and optimization of the bottom plates of the wheel legs, the bionic sand-crossing walking wheel has good smoothness on the hard road.

Description

technical field [0001] The invention relates to a walking wheel, in particular to a bionic sand-surfing walking wheel. Background technique [0002] With the depletion of non-renewable resources such as easy-to-exploit mineral deposits and oil and gas fields, my country's energy strategy has already aimed at the Gobi desert, which has harsh natural conditions and is difficult to mine. Judging from the current energy exploration situation, the oil and gas reserves in my country's Tarim Basin, Turpan Hami Basin and Junggar Basin account for 70% of my country's total oil and gas resources. However, due to the harsh natural environment of the Gobi desert and the limitations of desert engineering transportation equipment, most of the proven rich mineral deposits and oil and gas field resources are still unexploited. The development and utilization of agricultural resources in sandy land environment has extremely far-reaching significance to the survival and development of human ...
