Was.

[0003]

In a conventional cleaning car, when setting a dust box on a mounting portion, a pin must be locked to a hook while lifting a heavy dust box, and when the dust box is removed, the locking is released. After that, you have to pull it out so that it does not drop, even if you use attachments such as auxiliary wheels and lever arms,
It was difficult to accurately position the hook and the pin so that the positions coincided with each other, and the attaching / detaching operation was complicated. Further, there is a possibility that the dust box jumps due to the vibration when the vehicle climbs over the step, or that the dust box is disengaged due to a beat when a foreign object hits the bottom of the dust box during traveling, and the dust box may be inclined or fall off.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a cleaning truck which is easy to put on and take off, and in which a set dust box does not shift or come off during traveling. A supporting member is provided to abut on the bottom surface of the dust box so that a rotational moment acts on the dust box toward the rear lower side, and the supporting member is supported, and the supporting member is mounted on the supporting member between the dust box mounting portion and the dust box. There is provided a stopper means for preventing the mounted dust box from rotating rearward and downward in a predetermined posture state. The support member may be constituted by a rod body extending between left and right side plates in the dust box mounting portion, or a bottom surface of the dust box may be in contact with the support member and at least prevent movement backward from the mounting position. Means can be provided.

[0005]

The dust box can be securely mounted by placing the dust box so that the bottom is in contact with the support, and then pushing the dust box as it is, and can be easily removed by pulling it out. In addition, even if the dust box is lifted or vibrated up and down during traveling, it immediately returns to its original position due to its own weight. By configuring the support member with a rod body, the mounting operation of the dust box at the time of mounting becomes easy, and the reinforcing effect of the dust box mounting portion can be expected. In addition, by providing the positioning member, the user can feel the confirmation of mounting, and is excellent in stability at the time of mounting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment in which a self-propelled walking type cleaning machine according to the present invention is implemented will be described with reference to the drawings.
FIG. 1 shows a schematic structure of the entire cleaning truck. A body frame 1 has driving wheels 2 on a lower front side, a caster 3 is mounted on a lower rear side, and an engine 4 is mounted on a central portion. Have been. The upper surface of the body frame 1 is covered with a hood 5, and a blower 6 is provided in the hood 5.
A dust collector 6 composed of a and a filter 6b is accommodated, and a rotating brush 7 is provided between the drive wheel 2 and the caster 3. The driving wheel 2 includes a clutch mechanism 8 that can switch the rotation direction via a belt with respect to an output shaft 4 a of the engine 4, and a differential mechanism 9 and a chain 10 disposed in front of the clutch mechanism 8. On the other hand, the blower 6a and the rotary brush 7 are directly connected to the output shaft 4a of the engine 4 and the belts 11 and 12 so that the rotational force can be transmitted.

The above-mentioned clutch mechanism 8 is used for the body frame 1.
In the rear part, the switching operation is performed by the operation of a clutch lever 14 projecting obliquely upward along the steering handle 13, and the cleaning vehicle of the embodiment moves forward by pushing down the clutch lever 14. And then retreat by raising. The driving wheels 2 are provided independently on the right and left sides of the body frame 1, respectively. The output of the clutch mechanism 8 is transmitted to a differential mechanism 9 disposed above the driving wheels once, and the differential mechanism 9 From the drive wheels 2. As a result, between the left and right driving wheels 2,
2 is provided with a space, and the space is used as the dust box mounting portion 15.

As shown in FIG. 2, a rod 16 as a support member is provided below the dust box mounting portion 15 between the left and right side plates 15a, 15a.
On the inner wall surfaces 15a of the left and right side plates, regulating plates 17, which constitute stopper means together with stoppers 19 described later,
(17) is fixed. On the other hand, the dust box 18 mounted on the dust box mounting portion 15 has a rear side surface opened, and has handles 18a, 18a at upper right and left sides.
On both sides, stoppers 19 and (19) which constitute stopper means together with the regulating plate 17 are provided. The rod body 16 is provided forward of the center of gravity of the mounted dust box 18 so as to exert a moment on the mounted dust box 18 in a direction of turning rearward and downward, and a stopper 19 is provided. The regulating plate 17 (1
7) Dust box 1 mounted by contacting
8 is provided such that the height of the lower edge of the rear end thereof becomes an appropriate predetermined posture. It is more preferable that the contact portion of the stopper 19 be movable so that the height of the lower edge of the rear end of the mounted dust box 18 can be adjusted. Further, instead of the contact portion of the stopper 19, the regulating plate 17 may be movable.
A rubber grounding blade 18b is attached to the lower edge of the rear end of the dust box 18, and a positioning member 20 as positioning means is provided before and after a contact portion of the dust box 18 at the mounting position with the rod body 16. 2
0 is added. The positioning member 20 restricts the dust box 18 from moving backward at least from a predetermined mounting position. The positioning member 20 may be provided only on the front side.
If the positioning of the rod body 16 in 8 can be performed, the positioning member 20 does not necessarily need to be provided. For example, a structure in which the bottom surface of the dust box itself is grooved is used. The grounding blade 18b is for preventing dust from leaking from a gap between the dust box and the road surface, and for reliably taking the dust into the dust box. Therefore, the distance between the dust box and the road surface is small, and it is not always necessary to provide the dust box if there is no fear of dust leaking.

In the cleaning truck constructed as described above, when the engine 4 is started, the dust collecting device 6 and the rotating brush 7 operate, and the rotating brush 7 removes the dust scattered just below the cleaning truck from the front upper side. And the dust collecting device 6 sucks the fine dust soared up. Therefore, if the vehicle is moved by operating the clutch lever 14, dust is removed from the road surface in the movement locus, and the vehicle is cleaned evenly without being swept.

The mounting of the dust box 18 simply requires the rear bottom portion of the dust box 18 to be placed on the rod body 16 and slid backward in the pushing direction. Therefore, troublesome positioning is not required. The dust box 18 which is about to rotate is mounted in a state where the stopper 19 is brought into contact with the restricting plate 7 so that even if a foreign object collides with the bottom, the rear portion escapes upward so as to absorb the impact. In this case, the dust box does not fall off even if it jumps greatly.

In the above-described embodiment, the support member is constituted by a rod body having a horizontal structure. However, if a dust box can be put on the rod member, a pair of left and right protrusions partially contacting the bottom surface of the dust box. As shown, a pair of right and left rollers 21 and (21) may be used. Also, the stopper is not limited to the embodiment, and a structure for locking the rear lower edge, the front upper edge, or the side edges can be adopted as long as the rotation of the rear lower side can be prevented. It can also be used as positioning means.

Although the embodiment has been described with reference to a self-propelled walking type vehicle equipped with an engine, the invention is also applicable to a riding type, a battery driven vehicle and the like.

[0013]

According to the present invention, the dust box can be easily attached and detached, and even if the dust box jumps due to vibration or lifts up due to contact with foreign matter, the dust box will immediately return to its original position and fall off. Absent. In addition, the structure is simple, the utility value is high, and the rigidity can be increased if the supporting member is constituted by a laterally suspended rod body, and the stability at the time of mounting can be secured by providing the positioning means.
