Detailed description of the invention
As shown in Figure 1, the foliage pressure-vacuum machine of strap brake system, comprises casing 1, is provided with motor in described casing 1, and described casing is connected with protective cover 3 and airduct 2, and airduct is detachable, and then protective cover can closing air flue mouth.Described casing 1 is provided with main switch 12(K1) and safety switch 13(K2).
As shown in Figures 2 and 3, described foliage pressure-vacuum machine comprises main circuit 14 and a brake circuits 15.Described main circuit is in series with power supply, main switch 12, safety switch 13 and motor, described brake circuits is in series with safety switch 13 and motor, wherein safety switch 13 is a single-pole double-throw switch (SPDT), and safety switch is switched, in main circuit between main circuit and a brake circuits, when main switch 12 and safety switch 13 are all opened, main circuit conducting, motor normally works, in brake circuits, safety switch is switched to brake circuits from main circuit, brake circuits and conducting.
When deployed, first load onto protective cover 3 or airduct 2, due to protective cover 3 or airduct 2 being all provided with the device opening safety switch 13, safety switch is opened, then staff is opened switch trigger and is opened by main switch 12, and machine is in normal operating conditions, and its circuit diagram is as Fig. 2.
When protective cover 3 or airduct 2 take off, the device opening safety switch K2 that protective cover 3 or airduct 2 are arranged is separated from safety switch 13, make safety switch 13 brakes on loop, because rotor has along inertia motion during original normal work, this inertia motion makes the coil of rotor create inverse electromotive force, this inverse electromotive force stops again the inertia motion of rotor, thus make rotor stop in a short period of time not turning, also just make the fan blade be fixed together with rotor stopped rotation, circuit is now as Fig. 3.
As shown in Fig. 4 to Fig. 8, be provided with airduct fixed disassembly structure between casing 1 and airduct 2, the air channel in casing 1 is provided with air port, and airduct 2 tail end is provided with the ladder head that a diameter diminishes, and this ladder head just in time inserts air port after airduct 2 is installed.It is hinged with casing 1 that described airduct 2 tail end outer wall is provided with hinged seat 21, this hinged seat is located at ladder head front, hinged seat 21 is provided with an axis of rotation, and casing 1 is provided with the bearing 11 that can rotate for the axis of rotation of airduct, and bearing is provided with the pivot point rotated for axis of rotation.Described airduct 2 tail end outer wall and hinged seat circumference 180 degree, interval are provided with gland 22, and this gland is located on ladder head, and the corresponding described gland of described casing is provided with gland self-locking device 10.
