Is discharged to the ground from the ground chain 61 provided on the lower surface of the dust collection path 13 via the vehicle body 12.

The duct 18 is provided with a blower port 63 for blowing dust on the outer periphery of the filter 31 to remove dust, and a switching valve 65 for switching the blower port to the blower port 64 communicating with the inside of the cylindrical portion 21 and the blower port 63 is provided as a lever. It is rotatably provided by 67.

The vehicle body 12 is provided with front wheels 69 and rear wheels 71, and a handle 73 is provided at the rear.

A dust container 75 made of a non-breathable material is fixed to the lower end of the large cylindrical portion 25 via an annular packing 77. A swing rod 81 is pivotally attached to the vehicle body 12 at its lower end by a shaft 79, and an engaging portion 83 having a concave upper surface is fixed to the upper end of the swing rod 81. An engaging piece 85 protruding downward is engaged with the upper part, and an upper part on the rear side of the dust container 75 is detachably engaged with the lower surface of the large cylinder 25 by an engaging device 87. The swing rod 81 is provided so that its length can be adjusted by a turn bag 89 on the way, and is connected to the vehicle body 12 by a chain 91 to regulate the position where it swings downward. Wheels 93, 93 are provided on the lower surface of the dust container 75. The locking tool 87 is configured as follows. That is, the upper end of the hook 99 is pivotally attached by the shaft 101 to the lever 97 pivotally attached to the large cylinder 25 by the shaft 95, and the lower end of the hook 99 is packed with the flange portion 103 on the upper surface of the dust container 75. It is locked via 77. Car body 1
2, a switch 105 is provided, and in a state where the dust container 75 is engaged with the air exhaust device 19, the switch 105 is brought into contact with the swing rod 81 to operate to release the short circuit of the ignition primary circuit of the engine 3, With the dust container 75 disengaged from the air exhaust device 19,
The switch 105 operates when the switch 105 is disengaged from the swing rod 81 to short-circuit the ignition of the engine 3 in the primary circuit and stop the ignition in the secondary circuit to stop the engine.
One end of the blower pipe 107 is opened inside the exhaust pipe 23, and the other end is opened toward one side of the vehicle body 12 toward the ground surface near the front of the dust collection port 11.

As shown in FIG. 13, the switch 105 includes an electromotive coil 111 and a primary coil 1 which are sensitive to the magnet wheel 109.
It is provided so that the primary circuit 115, which connects the switch 13 and the switch 13 via the main switch 113, is short-circuited during operation. An electronic ignition device 117 is provided in the primary circuit 115, and when the voltage of the primary circuit 115 reaches a predetermined voltage, the primary circuit 115 is short-circuited to generate a high voltage in the secondary circuit 121 of the secondary coil 119 and the ignition plug It discharges at 123.

In the above embodiment, the dust sucked from the dust collection port 11 by the air suction device 1 enters the cylindrical portion 21 from the discharge port 17 and descends while swirling. 23 is discharged through the filter 31 to the outside, and rough leaves, paper scraps, etc. descend along the inner surface of the cylindrical portion 21 and descend from the gap between the shielding plate 27 and the large cylindrical portion 25 to be stored in the dust container 75. To be done.

When discharging the dust in the dust container 75, the handle 97 of the locking tool 87 is tilted rearward to release the locking of the flange 103 of the hook 99. When the worker holds the rear flange portion 103 by hand and removes the hook 99 and pulls the dust container 75 backward, the swing rod 81 swings, the switch 105 operates, and the engine 3 stops. At the same time, the dust container 75 descends and is placed on the ground. Dust container 75
When mounting the dust container 75, the engaging piece 85 at the front of the dust container 75 is engaged with the engaging portion 83 at the upper end of the swing rod 81 positioned by the chain 91. When the rear part is lifted and pushed forward, the rocking rod 81 rocks forward to lift the dust container 75, the switch 105 operates, the stop state of the engine 3 is released, and the lower surface of the large cylindrical part 25 is released. In the engaged state, the lever 97 is rotated to rotate the locking member 87.
It is fixed by.

In order to remove the dust that has accumulated in the filter 31, the switching valve 65 is switched by the lever 67 to blow air to the air outlet 6
It is ejected from 3 and sprayed on the outer peripheral surface of the filter 31. At this time, if the screw handle 55 is loosened and the cover 43 is rotated by the handle 49, the filter 31
The outer peripheral surface of the filter 31 also integrally rotates, and air is blown over the entire outer peripheral surface of the filter 31 to remove dust that has accumulated on the inner surface and drop into the dust container 75. The static electricity stored in the filter 31 is discharged to the ground from the outer perforated plate 37, the contact piece 59, the cylindrical portion 21, the large cylindrical portion 25, the vehicle body 12, and the earth chain 61.

The dust accumulated on the corners such as the curb and the wall is blown off by the air blown from the blower pipe 107 and sucked from the dust collecting port 11.

In addition, in the present invention, the dust container is not limited to the cylindrical shape, and
It may be formed in a rectangular box shape, and the swing rod and the locking tool may be provided at two places on the left and right.

Also, when removing the dust container and removing the locking tool, the dust container rotates downward around the engaging part of the upper end of the swing rod so that the bottom part rides on the wheel. The operation can be further facilitated by supporting the weight and then pulling it out backward and lowering it to the ground. Further, a swinging rod for supporting the front upper portion and the rear upper portion of the dust container may be separately provided, and the front and rear portions of the dust container may be simultaneously lifted by pushing them forward.

The exhaust air outlet may be provided by providing a cover outside the filter 31 and opening one end of the blower pipe in this cover. Moreover, you may provide the opening / closing valve which opens and closes a ventilation pipe.
Further, the blower pipe may be provided as a flexible pipe so that the blowing position and direction can be freely changed.
