Detailed description of the invention
Below in conjunction with the accompanying drawings and application principle of the present utility model is further described by specific embodiment.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, the technical solution adopted in the utility model is, a kind of automatic folding type pneumatic equipment blades device, including main shaft 1 and primary blades 2, it is characterised in that primary blades 2 circular array centered by main shaft 1 is arranged on main shaft 1；
Primary blades 2 includes main lobe frame 3, weathercock 4, countershaft 5, gear train 6, movable vane axle 7 and moving vane 8；Weathercock 4 is arranged at countershaft 5 top, fixes with countershaft 5 and is connected；Being provided with multiple moving vane 8 in primary blades 2, moving vane 8 is evenly distributed in primary blades 2；Each action blade 8 is connected with a movable vane axle 7, and the two ends of each movable vane axle 7 are flexibly connected with main lobe frame 3, and movable vane axle 7 can be around self axle center rotating on main lobe frame 3；Countershaft 5 is parallel with main shaft 1, and is connected by gear train 6 with between movable vane axle 7.
Primary blades 2 is when main shaft 1 rotates, and weathercock 4 also drives countershaft 5 rotation, and the rotational kinetic energy of countershaft 5 passes to movable vane axle 7 by gear train 6, and movable vane axle 7 passes to moving vane 8, moving vane 8 servo-actuated rachis 7 uniform rotation, it is achieved that the automatic steady folding of moving vane 8 again.
The rotation of one countershaft 5 drives the servo-actuated rachis of multirow moving vane 87 to rotate.
Primary blades 2 quantity is even number, and quantity is more than or equal to 2.
