Description

A kind of four axis plant protection unmanned planes for being readily transported and loading and unloading

Technical field

Unmanned plane is the utility model is related to, belongs to unmanned air vehicle technique field, more specifically, the utility model is related to one kind The four axis plant protection unmanned planes for being readily transported and loading and unloading.

Background technology

Referred to as " unmanned plane ", english abbreviation is " UAV " to UAV, using radio robot and is provided for oneself The not manned aircraft that presetting apparatus manipulates, or fully or intermittently independently operated by car-mounted computer.[1]

Compared with manned aircraft, unmanned plane is often more suitable for the task of those too " slow-witted, dirty or dangerous ".Nobody Machine presses application field, can be divided into it is military with it is civilian.Military aspect, unmanned plane are divided into reconnaissance plane and target drone.Civilian aspect, unmanned plane + sector application, is that unmanned plane has really just needed；At present take photo by plane, agricultural, plant protection, miniature self-timer, express transportation, disaster relief, Observe wild animal, monitoring infectious disease, mapping, news report, electric inspection process, the disaster relief, movies-making, manufacture romance etc. field Application, greatly expanded the purposes of unmanned plane in itself, developed country is also in actively extension sector application and development unmanned plane Technology.

Plant protection unmanned plane, as the term suggests be for agriculture and forestry plant protection operation UAV, the type unmanned aerial vehicle By flying platform (fixed-wing, helicopter, Multi-axis aircraft), navigation fly control, spraying mechanism three parts form, pass through ground remote control Or navigation flies control, to realize spraying operation, can spray medicament, seed, pulvis etc..

Go out within 2016 according to space occasion net《The civilian unmanned plane market analysis of China and Potential Prediction (2016 examination distribution)》One book To introduce, the agricultural plant protection unmanned plane in China is still in the starting stage at present, according to statistics, China's plant protection unmanned plane ownership in 2014 For 695 framves, total 4,260,000 mu of working area；China's plant protection unmanned plane ownership in 2015 is 2324 framves (31 province's statistics), total to make 1152.8 ten thousand mu of industry area, increasing degree are respectively 234%, 170.6%.Although amount of increase is obvious, generally speaking, the plant in China It is not yet ripe to protect unmanned plane system.[1] domestic plant protection unmanned air vehicle technique and properties of product are uneven at present, in numerous products absolutely It is rare to disclosure satisfy that large area high intensity plant protection sprinkling requires.

Plant protection unmanned plane has gradually applied to the fields such as agricultural, planting industry, gardens environmental protection as emerging technology product, Although technology has tended to be ripe, in present plant protection unmanned plane product, during manufacture, assembling and use, still There are problems that some or defect, such as：1st, in the fabrication process, its main body and cantilever, propeller etc. are all integral types to unmanned plane Structure, it is extremely inconvenient in processing and transportational process, secondly also it is not easy to replace main body, cantilever or the propeller damaged；2nd, nothing Man-machine main body is substantially using integral structure, the i.e. flight control system of unmanned plane, navigation system, battery, all kinds of controls Device and sensor and medicine-chest processed etc. be all it is integrated be built in casing, whens handling, is extremely inconvenient, and when single electrical part damages Bad when, is extremely onerous, it is necessary to dismantling whole casing can be replaced, time-consuming and laborious, and is also unfavorable for maintenance maintenance.3rd, nobody For machine since electrical part is more, cabling is complicated, easily causes circuit mutually to wind, extremely chaotic, be unfavorable for malfunction elimination and Maintenance, or even overall electrical part failure caused by circuit damage can be caused.4th, unmanned plane also needs to during Standard The connection of circuit is realized at the same time, also to be looked into again when bringing inconvenience to assembling, and subsequently replace electrical part, structural member Corresponding circuit is looked for, inconvenience is brought to assembling, maintenance.5th, unmanned plane main body is all the monolithic construction of injection molding mostly, I.e. unique inconvenience after the completion of the manufacture of its structure and size, for no environment, sprinkling demand, then needs using different capabilities, type Number type, this undoubtedly limits the use scope of unmanned plane and field, can not meet unmanned plane a wide range of applicability requirement. 6th, the rack in unmanned plane main body can not fold after mounting, cause to occupy larger space in transportational process, waste transport material Material, adds cost of transportation.7th, the propeller of existing unmanned plane is directly installed on cantilever end, Wu Fagen generally by motor According to needing to select its spacing with main body, so that when there is 5 situation in main body, it is also necessary to corresponding cantilever is replaced, to meet Propeller acts on its lift.
