[0002] With modern agriculture, environmental protection, environmental governance and other fields rapidly entering the mechanization and informationization era, the demand of amphibious operation vehicles that can enter lakes, canals, wetlands and other areas that traditional machines usually cannot enter is increasing, and since amphibious operation vehicles need to have the ability to run on water and land at the same time, they often use two sets of propulsion mechanisms to achieve this, resulting in complex propulsion equipment for operation vehicles, poor reliability and high operation difficulty, so a track device that can simultaneously satisfy amphibious operation has great significance.

[0003] Chinese patent publication No. CN112248730A discloses a track paddle integrated amphibious unmanned vehicle, which comprises a hull, two driving wheels and two driven wheels, the hull is of a rectangular structure, further comprises a track and a plurality of paddles, the two driving wheels are installed side by side along the width direction of the hull at the front end of the hull, the two driven wheels are installed side by side along the width direction of the hull at the rear end of the hull, the driving wheels are connected with the driven wheels through the track, and the plurality of paddles are installed on the outer surface of the track along the length direction of the track.

[0004] It can be seen that the track paddle structure used by the above-mentioned track paddle integrated amphibious unmanned vehicle requires precise intermeshing of the paddle structure in the movement process, and once the intermeshing timing is not accurate or the intermeshing precision is not high, the water cavity will be filled with water, which has high processing difficulty and poor reliability; the paddles in the underwater part are mostly in the intermeshing state and cannot push the water to generate power, resulting in poor power of the design in water; the amphibious unmanned vehicle supported by this track design obtains its buoyancy from the cavity formed by the intermeshing of the paddles in the middle parallel section, which has small buoyancy and poor load-carrying capacity, so it can only be used as the mechanism of the unmanned vehicle and cannot carry various large operation tools, and the application range is narrow.
