Title:
SUCTION DUCT OPENING DEVICE FOR CLEANING MOTOR VEHICLE
Document Type and Number:
Japanese Patent JP3804714
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to operate a dust removing device continuously, intermittently and efficiently while a suction duct is tightly closed and a hopper chamber is completely still.
SOLUTION: A seal plate 16 is provided for a suction inlet 14 of a suction duct 6, and an operation lever 22 is supported near a driver's seat. A turn plate 17 of a seal plate 16 and a turn plate 28 of the operation lever 22 are coupled with a first spring 34 and a second spring 36. The first spring 34 keeps a constant length in the range of a first position and a second position of the operation lever 22, releases the seal plate 16 at the first position and closes the seal plate 16 at the second position. The second spring 36 pushes the seal plate 16 to an open stopper 18 or a close stopper 19 and holds it at the dead point passing position of the turn plate 17. At the third position of the operation lever 22, the turn plate 28 turns on a switch 27 of the dust removing device at the third position of the operation lever 22, and the first coil spring 34 automatically resets the operation lever 22 to the second position.
