2. Description of the Related Art As shown in FIGS. 6 to 8, a conventional floor cleaning vehicle comprises a vehicle 51 and a dust box 52 provided on the front side thereof. The dust box 52 is rotatably provided by a support shaft (not shown) provided on the vehicle. When a telescopic cylinder (not shown) extends, the dust box 52 rises while rotating around the support shaft. Therefore, the dust box 52 can be stopped at the discharge position for discharging the dust. On the other hand, when the telescopic cylinder contracts,
The dust box 52 descends while rotating around the support shaft. Therefore, the dust on the floor surface can be swept into the dust box 52 and stopped at the collection position by the rotation of the main brush (not shown) that rotates at the bottom of the vehicle 51.

The dust box 52 is composed of a box portion 53 in the shape of a rectangular box and a connecting portion 54 in the shape of a rectangular box on the upper portion of the box portion 53. That is, the box portion 52 is formed with an opening 53a for collecting dust. The box portion 53 and the connecting portion 54 are in communication with each other, and the connecting portion 54 is provided with a filtering device (not shown). Therefore, the inside of the dust box 52 is brought into a negative pressure state by the filtering device provided in the connecting portion 54, and the dust is collected in the dust box 52.

In FIG. 6, the dust box 52 is located at a collecting position where dust can be collected in the box portion 53 by sweeping up a main brush (not shown). At this time, the worker S runs the vehicle 51 to clean the floor surface, and further sweeps the dust on the road shoulder into the work area of the main brush by the side brush 55.

[0005]

By the way, when the vehicle 51 is run so that the side brush 55 contacts the road shoulder, the operator S operates the vehicle 51 while checking how close the side brush 55 is to the road shoulder. Will be done. However, as shown in FIG. 6, since the connecting portion 54 of the dust box 52 has a rectangular box shape, the operator S cannot easily visually recognize the side brush 55 from the driver's seat. Therefore, the worker S has to lean out and visually check how much the side brush 55 has approached the road shoulder, which causes a problem of poor workability.

FIGS. 7 and 8 are views showing that the dust box 52 is stopped at the discharge position by an unillustrated telescopic cylinder and the dust in the dust box 52 is discharged. In this case, since the connecting portion 54 of the dust box 52 has a rectangular box shape, the operator S cannot easily see the opening 53a of the rising box portion 53 from the driver's seat. That is, the state of the dust discharged from the dust box 52 and the confirmation of whether the dust is completely discharged cannot be easily visually recognized from the driver's seat. Therefore, the worker S
Must lean out and visually recognize the opening 53a of the dust box 52, which causes a problem of poor workability.

The present invention has been made to solve the above problems, and an object thereof is to improve the visibility of the side brush from the driver's seat and the visibility of the state of dust discharged from the dust box. It is to provide a dust box for floor cleaning vehicles.

[0008]

In order to solve the above-mentioned problems, the present invention comprises a dust box in a floor cleaning vehicle comprising a storage portion for collecting dust and a support portion connected to the storage portion. , The dust box is rotatably provided around the base end of the support portion so as to be located at a collecting position for collecting dust on the floor surface and a discharging position for discharging the collected dust, respectively. The gist of the invention is that the support portion of the dust box is formed so as to expand toward the storage portion.

[0009]

In the state where the dust box is in the collecting position, the supporting portion is designed to expand toward the accommodating portion, so that the side brush can be easily visually recognized from the driver's seat of the floor cleaning vehicle. Also, when the dust box is in the discharge position, the accommodating part has a square box shape and the supporting part expands toward the accommodating part. Therefore, it is easy to visually recognize the accommodating part of the dust box from the driver's seat. You can
