The invention discloses an energy-saving and environment-friendly unmanned helicopter including a body. A propeller apparatus is arranged on the body and includes a main shaft, an adjustment shaft andpropellers. The main shaft is rotatably arranged on the body and has a hollow structure, wherein the adjustment shaft is sleeved with the main shaft. A guiding groove is formed in the inner side wallof the main shaft axially. A guiding bar, which is matched with and slides in the guiding groove, is arranged on the outer side wall of the adjustment shaft axially. Three propeller linking rods areuniformly arranged on the outer side wall of the main shaft. One propeller blade is connected to each blade linking rod in a rotational manner. Three support rods are uniformly arranged on the outer side wall of the adjustment shaft. In the propeller apparatus, the axial position of the adjustment shaft is changed by driving an adjustment tap through a first air cylinder, thus driving second adjustment rods to adjust the dip angle of the blades. The unmanned helicopter is convenient to adjust, has simple structure and high reliability, and is long in service life.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an energy-saving and environment-friendly unmanned helicopter. Background technique [0002] At present, the structure for adjusting the blade angle in the propeller device used by unmanned helicopters has the problems of unreasonable design and short service life; Do not have the wheel hub device that can travel on land conveniently on the people's helicopter, need to improve. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide an energy-saving and environment-friendly unmanned helicopter, so as to solve the problems of unreasonable design and short service life of the structure for adjusting the blade angle in the propeller device used by the unmanned helicopter in the prior art; The structural design of the medicinal liquid mixing device is unreasonable, a...
