The horizontal support means is configured to support the vehicle so that it can be tilted forward only in the direction of jumping upward from. The stopper 11 is composed of a bracket 11a fixed to the dust box 8 and a screw shaft 11b attached thereto, and the contact position of the screw shaft 11b with respect to the restriction piece 9c can be adjusted.

When the dust box 8 is supported by the horizontal posture support means, the sweep port 7 is always opposed to the main brush 4. However, in this state, the pin 10 is used as a pivotal fulcrum. 7 side can jump up,
Therefore, when the sweeper is running, the dust guide lip 8a provided at the sweeping port 7 can get over large dust on the road surface.

As shown in FIG. 2, the machine body 1 is provided with a pair of upper and lower guide rails 12 and 13 as supporting means for supporting the dust box 8 when the dust box 8 is tilted forward for dumping dust. This guide rail 12,
13 is set at a position higher than the horizontal posture support means and is attached to the left and right inner wall surfaces of the box storage portion 6, and is engaged with a roller 14 attached to the outer surface of the dust box 8 near the sweep opening 7. It is possible. That is,
When the dust box 8 is tilted forward with the pin 10 engaged with the pin engaging portion 9b on the front side of the support rail 9, the position of the roller 14 is adjusted so that the upper guide rail 12 has an eyebrow shape. On the other hand, the rear portion of the lower guide rail 13 is opposed to the upper guide rail 12 at a predetermined interval and has a chevron portion 13a so that the roller 14 can easily move. The lower guide rail 13 extends forward horizontally or slightly upward to form a guide portion 13b of the roller 14 when the box is pulled out, and the roller 14 is fitted to the front end portion of the guide portion 13b. Therefore, the dust box 8 is provided with the recess 13c that constitutes the falling support portion.

That is, the upper guide rail 12 provided on the machine body 1
However, when the dust box 8 is tilted forward, it engages with the roller 14 to form a high position support means for supporting the dust box 8 at the tilted position. A lower guide rail 13 provided on the machine body 1 and provided with a roller rolling guide portion 13b and a recess 13c formed at a front end portion of the guide portion 13b.
Of the dust box 8 constitutes a drawer fall support means for pulling out the dust box 8 forward and falling down. The concave portion 13c of the lower guide rail 13 serves as a tipping support portion, and the roller 14 serves as a tipping fulcrum of the dust box 8.

A ring-shaped stopper 16 is provided on the upper surface of the dust box 8 to hold the dust box 8 in a fallen posture by engaging with a hook 15 provided on the body 1 side. Further, in FIG. 1, reference numeral 19 is an auxiliary brush for bringing dust on the road surface to the center during cleaning work.

The support device for the dust box 8 of the present embodiment is configured as described above, and the operation of discharging dust manually will be described with reference to FIGS. 4 to 8. FIG. 4 shows normal cleaning, and the dust box 8 is supported by the support rails 9 of the machine body 1 in a substantially horizontal posture. As shown in FIG. 5, by engaging the handle 17 of the dust box 8 and pulling it forward while getting into the garbage dumping place, the engagement position of the pin 10 with respect to the support rail 9 is changed to the rear pin engagement portion 9b. From the front to the pin engaging portion 9a on the front side, and the dust box 8 is supported by using the pin engaging portion 9a as a fulcrum.
When the vehicle is tilted forward, the roller 14 comes into contact with the bent portion of the upper guide rail 12, and further forward tilt is restricted.

In this state, when the roller 14 is pressed against the upper guide rail 12, the front side of the dust box 8 is lifted and pulled toward you, so that the roller 14 moves the chevron portion 13a of the lower guide rail 13 as shown in FIG. You will get over it. By operating in this way, the support point of the dust box 8 with respect to the machine body 1 becomes the support rail 9 up to that point.
From the side to the side of the lower guide rail 13 located at a higher position than that. Then, when the dust box 8 is pulled toward you, the roller 14 rolls along the guide portion 13b of the lower guide rail 13 and the roller 14 fits into the recess 13c as shown in FIG. That is, the dust box 8 is pulled out to the front of the machine body 1, and the movement in the front-rear direction is regulated to some extent by the fitting of the roller 14 into the recess 13c serving as the falling support portion.

Therefore, when the front side of the dust box 8 is pushed up in this state, the dust box 8 is tumbled with the sweep port 7 facing downward with the concave portion 13c as the fulcrum of rotation as shown in FIG. If so, the stopper 16
It is held by hooking the hook 15 on. Thus, the dust box 8 that has been turned over has its sweeping port 7 largely separated from the road surface, so that the dust in the dust box 8 can be discharged by one turn operation.

The operation of returning the dust box 8 to the original position after the dust is discharged is performed in the reverse order described above after the aircraft 1 is slightly retracted from the dump site. If necessary, the dust box 8 can be detached from the machine body 1 by pulling it forward as it is from the horizontal support state shown in FIG.

In this embodiment, when the dust box 8 is tilted forward as shown in FIG. 6, the engaging position of the pin 10 with respect to the support rail 9 is changed to the front side. This is because the rear end of the dust box 8 is the main brush 4. Alternatively, it is carried out to avoid interference with the front plate forming the brush chamber 5. Therefore, when the dimensions are set so as to avoid this interference problem, the engagement position of the pin 10 is not changed and the front position is changed. It does not matter even if the tilting operation is performed.

(Effect of the Invention) As described in detail above, according to the present invention, the dust box is pulled out to the front of the machine body to perform the tipping operation for discharging the dust, and at that time, the sweep opening is separated from the ground. As a result, it is possible to effectively discharge dust with one overturning operation, which is very useful for improving work efficiency. Further, since the dust box is pulled out while the sweeping port side is pulled up, the lip is not damaged at the time of pulling out.
