Abstract

The invention provides a bionic earthworm device and a working method thereof. The earthworm device comprises a plurality of telescopic units which are connected through a steering unit; the telescopic unit comprises a push rod mechanism and an elastic piece arranged in the head-tail direction. The telescopic action of the telescopic unit is driven by the deformation of the elastic piece under the action of the push rod mechanism and the natural recovery of the elastic piece; when the earthworm device moves, the telescopic units execute telescopic actions according to a preset telescopic sequence so as to drive the earthworm device; the steering unit is provided with driving force by a micro screw rod sliding table; when the earthworm device steers, micro lead screw sliding tables of the steering unit are matched with one another to push a fisheye rod end joint bearing, and then the mutual included angle of each telescopic unit with the ball center of a single-rod ball joint bearing as the original point is controlled so that the body of an earthworm can be bent. The miniature electric push rod and the miniature lead screw sliding table serve as power sources, rapid restoring force is provided through the metal spring piece, and the operation speed is high.

Description

technical field [0001] The invention relates to the technical field of bionic machinery, in particular to a bionic earthworm device and a working method thereof. Background technique [0002] In recent years, the rapid development of industry and agriculture has caused soil pollution and soil degradation to become a global environmental crisis. The problem of soil pollution and degradation needs to be solved urgently, and how to realize economical and rapid soil detection and restoration is the key. Earthworms dig burrows to loosen the soil and decompose organic matter, creating good conditions for the growth and reproduction of soil microorganisms. They play special roles in soil improvement, pollution elimination, protection of the ecological environment, material cycle, and biodiversity. Combining the above-mentioned advantages of earthworms, bionic earthworms can play an important role in soil restoration, geological exploration, pipe plugging and emergency rescue. How...
