Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a dust box for a floor cleaning vehicle.

[Conventional technology]

In the floor cleaning vehicle, as shown in FIG.
The side brushes 21 provided on the bottom of the front part of the vehicle 20 scrape up dust on the walls of the vehicle running path, and as the vehicle 20 travels, the dust is collected on the main brush 22 provided on the bottom of the center part of the vehicle 20. It is swept up by rotation and sent into the dust box 23 inside the vehicle 20. After the cleaning is completed, the dust box 23 is removed from the vehicle 20 and the dust inside is thrown away.

The above-mentioned dust box 23 is arranged in an oblique manner that becomes lower toward the opening 24, and is configured to guide dust from the main brush 22 by a rubber guide plate 25 hanging from the opening 24 and send it into the opening 24. It becomes.

[Problem to be solved by the invention]

However, the guide plate 25 is supported near the opening 24 of the dust box 23 by a stepped support portion 27 that projects upwardly from the bottom surface 26. The collected dust gathers in front of the bottom surface 26 according to its inclination, and is deposited in front of the stepped support section 27. These dust particles are moist,
If it becomes viscous, the amount of accumulated dirt increases and may block the opening 24 of the dust box 23 as shown by the two-dot chain line, making it difficult to collect the dirt from now on and making efficient cleaning impossible.

This invention was made to solve the above-mentioned problems, and its purpose is to move the dust accumulated at the dust box opening to the back of the dust box, thereby creating a floor surface that can be cleaned efficiently. Our goal is to provide dust boxes for cleaning vehicles.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a main brush that rotates at the bottom of a vehicle and sweeps up dust on the floor surface, and a main brush that sweeps up dust and dirt that is swept up by the main brush at a position opposite to the main brush. An opening for guiding the inside, and a step that hangs from the opening and supports the guide part that guides dust from the main brush to the opening near the opening on the bottom surface which is sloped downward toward the opening. A floor cleaning vehicle is provided with a dust box having a shaped support part, and an operating means connected to the dust box, and the dust box is raised so that the bottom surface of the dust box is higher toward the opening side based on the operation of the operating means. (It is equipped with a rotation fulcrum for rotation to the desired posture.)

[Effect]

By employing the above-described means, this invention has the advantage that when the bottom of the dust box is in an inclined position where it is as low as the opening, the collected dust accumulates in front of the stepped support near the opening. When operated, the dust box rotates around the rotational fulcrum and is switched to an oblique position where the bottom surface is higher as the opening approaches. As a result, the dust accumulated near the opening is moved inside the dust box.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

When a main brush 1 provided at the center of the bottom of a known floor cleaning vehicle is rotated by a drive mechanism, dust on the floor is swept up and collected into a dust box 2 through an opening 3. The dust box 2 has a suspension shaft 4 as a rotation fulcrum provided at the front of both side walls, and is placed on a support piece 5 of the frame of the vehicle.
is suspended in a diagonal collection position that becomes lower as the opening 3 approaches. The lower end of the opening 3 of the dust box 2 is located close to the floor at a slight distance, and is supported by a stepped support 7 that projects upward on the bottom 6 near the opening 3. A guide plate 8 made of a resin material or the like is suspended so as to be in sliding contact with the floor surface. Of the dust sent by the rotation of the main brush 1, the dust that flies between the bottom end of the dust box 2 and the floor surface is guided into the opening 3 by the guide plate 8, allowing efficient collection of dust. be exposed. The dust collected in the dust box 2 gathers on the opening 3 side along the slope of the bottom surface 6 and accumulates in front of the stepped support section 7.

An abutment bolt 9 is attached to the upper part of one side of the dust box 2.
However, gripping portions 10 each formed by bending a tube material are fixedly provided on the upper surface of the front portion.

This grip part 10 is attached to the dust box 2 from the frame of the vehicle.
This is for grasping and lifting when separating.

There is a switching lever 11 as an operating means in the driver's cabin of the vehicle.
is provided so as to be rotatable back and forth, and its lower end is fixed to the rotation shaft 12. A first link lever 13 is fixed to the rotation shaft 12, and this link lever 13 is connected to a second link lever 15 which is rotatably supported on the vehicle frame by a rotation shaft 14 above the dust box 2. It is connected to via a rod 16. These first and second link levers 13, 15 and rod 16 constitute a rotating means.

The front end surface 17 of the lower end of the second link lever 15 contacts the abutting bolt 9, and when the switching lever 11 is switched to the operating position shown by the two-dot chain line, this operation is caused by the first link lever 13 and It is transmitted to the second link lever 15 via the rod 16, which rotates clockwise about the rotation shaft 14. Then, the second link lever 15
7, the abutting bolt 9 is pressed forward, and the dust box 2 receiving this pressing force rotates a predetermined amount counterclockwise around the suspension shaft 4, and the bottom surface 6 moves higher toward the opening 3. It becomes a posture.

When the dust box 2 is changed to the moving position, the dust accumulated on the opening 3 side of the bottom face 6 during the collecting position is moved inward of the dust box 2 along the bottom face 6. Therefore, if this attitude change is made appropriately, the opening 3 of the dust box 2
There is no possibility that a large amount of dust will accumulate on the surface and obstruct the collection of new dust.

Further, the dust box 2 is suspended from the support piece 5 of the frame via the suspension shaft 4, and is configured to be separable from the link device, so that when it needs to be removed, it can be easily removed from the vehicle by grasping the grip 10 and lifting it. Can be removed from the frame.

Further, by adjusting the screwing amount of the abutment bolt 9, the degree of inclination of the bottom surface 6 when the dust box 2 is in the moving position can be arbitrarily changed. Therefore, when highly viscous and moist dust accumulates, the slope can be changed depending on the nature of the dust, such as by increasing the slope, and the collected dust can be removed inward from the vicinity of the opening 3 of the dust box 2. can.

Note that the embodiments described above can also be implemented in the following embodiments.

■As shown in Fig. 2, the front part of the bottom surface 6 of the dust box 2 is formed deeply to form a retention part 18, and when the dust box 2 is changed from the collecting position to the moving position, dust is removed from the retention part 18. to enter. Then, when the dust box 2 returns to the collecting position again, the dust is prevented from moving toward the checkpoint section 3 side.

■As shown in FIG. 3, a link mechanism 1 is connected to the switching lever 11 at the center of the interior of the dust box 2.
A shielding plate 19a linked to the dust box 2 is provided so as to be openable and closable, and when the dust box 2 is in the collection position, the lower part of the dust box 2 is blocked from the front and back by the shielding plate 19a, so that the dust in the rear part moves to the opening 3 side. prevent. And the switching lever 1
When the dust box 2 shifts to the moving position by the operation 1, the shielding plate 19a is rotated in the opening direction by the action of the link mechanism 19 interlocked with the switching lever 11, and the dust on the opening 3 side is moved to the rear. shall be.

(2) The dust box 2 is held in the collecting position when the vehicle is moving forward, and is automatically shifted to the moving position when the vehicle is moving backward, and the dust in the dust box 2 is moved rearward as the vehicle moves backward.

〔effect〕

As described in detail above, according to the present invention, by moving the dust accumulated at the dust box opening to the back of the dust box, an excellent effect is achieved in that efficient cleaning work can be performed.
