Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a road cleaning vehicle in which a cleaning unit can be freely connected to and detached from a traveling body. For example, if a snow removal unit or the like is connected, the vehicle can be used as a snow removal vehicle, and is characterized by being economical and capable of being used for multiple purposes as a traveling body.

[Conventional technology]

All of the road surface cleaning vehicles that have been provided in the past have been constructed as dedicated cleaning vehicles, with a traveling device section and a cleaning device section constructed as one unit (Japanese Utility Model Publication No. 17934/1983).
Publication No. 55-41844, Publication No. 45-3163
Publication No. 3).

[Problem that the invention seeks to solve]

The above-mentioned conventional road cleaning vehicle has a traveling device part and a cleaning device part that are integrated, so it has only a single function as a cleaning vehicle, and the traveling device part cannot be used for other purposes, making it economical. I couldn't say that.

Therefore, the present invention focuses on the cleaning device part, ie.

The cleaning unit is connectable to and detachable from the traveling device part, that is, the traveling body.

Therefore, by removing the cleaning unit, the traveling body becomes independent and can be used as a traveling vehicle as is, or can be used as a snow removing vehicle by connecting other pre-configured units, such as a snow removal unit.

Furthermore, in the above-mentioned conventional road cleaning vehicles, the cleaning device part and the traveling device part cannot be separated, so internal maintenance and inspection is troublesome and time-consuming, and the whole vehicle is large and heavy. It was extremely time-consuming to handle during maintenance and inspection.

The present invention eliminates the above drawbacks.

[Means for solving problems]

The present invention solves the above problems, and includes a side gutter brush rotated by a hydraulic motor, a hopper provided above the brush and moved up and down by a hydraulic cylinder, and a side gutter brush provided from the rear toward the hopper opening. A cleaning unit consisting of a conveyor for sweeping up dirt, etc.;
The cleaning unit is configured to include a traveling body having a retaining and connecting portion for the cleaning unit at the tip end thereof.

[Made by Kou]

In the present invention, the cleaning unit (B) is attached to the traveling body (A).
) can be connected and removed freely, and by removing the cleaning unit (B) and connecting another unit, such as a snow removal unit, to the traveling body (A), it can be used as a snowplow, making the traveling body (A) multipurpose. available and economical.

In the present invention, when the traveling body (A) and the cleaning unit (B) are connected, the front surface of the retaining connection part (9) of the traveling body (A) and the contact surface (2) of the cleaning unit (B) are brought into close contact with each other. The stop part (9α) enters and locks into the lock receiving hole (to), the matching part α0 fits into the recess α◆, the mounting hole Ql) and the mounting hole (G) are matched, and the bolt is secured. It is worn.

Next, when removing the cleaning unit (B) from the traveling body (4), the cleaning unit (B) is stably supported by the support leg α'I) (to), and then the bolt) Then, the locking portion (9α) of the traveling body (A) is removed from the locking hole (to) of the cleaning unit (B).

In the case of the embodiment shown in the drawings, the removal work is performed by controlling the extension of the cylinder (B) to move the front wheel (1) provided at the tip of the front wheel arm (2) in the upward direction, and vice versa. 9), then lower the traveling body (A
) should be set back.

As a result, the traveling body (A) is made independent and can be used as a traveling vehicle as is, or can be used as a snow removing vehicle by connecting other pre-configured units, such as a snow removing unit.

〔Example〕

The drawing shows one embodiment of the present invention, and shows a traveling body (A
) and a cleaning unit (B).

The traveling body (A) is configured to be freely movable and includes front wheels (1), rear wheels (2), an engine room (3), a driver's cab (4), a tank (5), and the like.

In the case of the drawing example, the front wheel (1) is located in the engine compartment (3)
The front wheel arm (2) is provided at the tip of the front wheel arm (2) whose center portion is pivotally supported on the side, and the front wheel arm (2) is provided at the rear end of the front wheel arm (2).
2) Connects the piston rods of the two cylinders that rotate the cylinder.

That is, when the cylinder 3υ is controlled to extend, the front wheel (1) is moved in the upward direction, and as a result, the engine room (3), the driver's cab (4), and the cleaning unit CB) are lowered, and the cleaning unit (B) is moved upward. It is grounded,
Conversely, when cylinder 2 is compressed, the front wheel (1) is moved in the downward direction, and as a result, the engine (3) and driver's cab (
4) and the cleaning unit (B) are raised so that it can run at high speed as a traveling vehicle.

The cleaning unit (B) includes a side gutter brush (6), a hopper (8) provided above the brush and moved up and down by a hydraulic cylinder (7), and a hopper (8) that is moved up and down by a hydraulic cylinder (7) from the rear of the side gutter brush (6) to the opening of the hopper (8). It consists of a conveyor aI for sweeping up earth and sand.

In the present invention, the cleaning unit (B) is connectable to and detachable from the traveling body (A). Therefore.

A retaining connection part (9) for connecting the cleaning unit (B) is provided at the tip of the traveling body (A).

The locking connection part (9) is configured so that the cleaning unit (B) lockingly connected in front thereof does not move horizontally or vertically with respect to the traveling body (A).

That is, a locking connection part (9) having a substantially triangular side surface is formed in the approximate center of the tip of the traveling body (A), and an intermediate locking part (9α) is projected above the locking connection part (9) for engagement. Connecting part (9
), a substantially box-shaped fitting part 01 is formed on the upper surface of the above-mentioned engaging connecting part (9) and the locking part (9α). Inside the driver's cab (4) side of the compatible part (11), a pedal, operation panel, etc. are provided for driving operations.

Furthermore, mounting holes αω are provided below both sides of the engagement connection portion (9).
is provided.

Next, regarding the cleaning unit (B), the rear part of the cleaning unit (B) includes the retaining connection part (9), the locking part (9ff), and the matching part θQ at the tip of the traveling body (A).
The handle and handle are shaped to fit the hole α.

That is, the rear part of the cleaning unit (B) has a contact surface (to) with the front surface of the retaining connection part (9), a locking hole (to) into which the locking part (9α) is inserted, and a compatible part αO. A bracket 0Q is provided with a matching recess α◆ and a mounting hole QcJ that matches the mounting hole α■.
) is fixed.

In the figure, aη is a support leg used when removing or connecting the cleaning unit CB), and is configured to be able to advance downward and return freely.

Note that the support legs a are provided on both sides of the cleaning unit (B), and the cleaning unit (B) is stably supported by the two support legs (b) and the support leg α provided at the tip. It is.

The road cleaning vehicle of the present invention having the above structure differs from conventional road cleaning vehicles in that the cleaning unit can be removed from the traveling body, and therefore it can be used not only as a road cleaning vehicle but also as an independent vehicle with the traveling body. In addition, since the cleaning unit is provided with an engagement connection portion at the tip, it can be used by connecting other units, such as a snow removal unit, using the engagement connection portion.

〔Effect of the invention〕

According to the present invention, the present invention can be used for multiple purposes such as a traveling body, is economical, and has the effect of facilitating maintenance and inspection work.
