Description

[Detailed description of the invention] This invention relates to a support mechanism for a transfer device in a roadside cleaning vehicle, which makes it possible to clean the edges of roadside obstacles such as guardrail poles, which was previously impossible. be.

Generally, roads are formed with convex surfaces, so dirt, garbage, etc. (hereinafter referred to as earth and sand), which are objects to be cleaned, accumulate on the sides of the road. However, even if cleaning was done using a cleaning truck, there were guardrails, etc., which made it impossible to clean the edges beyond this.

Therefore, the inventors of the present invention made it possible to clean the side of the road by passing the cleaning device itself under the guardrail and extending it to the end.

However, for cleaning the end side A of road side obstacles such as guardrail poles (see Figure 1), the cleaning device is attached to the front of the aircraft so that it can be moved left and right and up and down via two links. This was impossible even with roadside cleaning vehicles.

This invention solves this problem by adding a twist to the two links that connect and support the cleaning device and the machine body.

Hereinafter, specific embodiments of this invention will be described based on the drawings.

A road side cleaning vehicle implementing this invention is a self-propelled vehicle 1 with a cleaning object transfer device 2 attached to the front of the vehicle.

The self-propelled vehicle 1 is a crawler or wheel running device 3
A chassis 4 is installed on top of the vehicle, and an engine 5, a seat 6, a driving device 7, etc. are installed on top of this chassis 4.

The transfer device 2 accommodates a transfer body 9 such as a spiral screw in a cover 8 having an arcuate cross section, and is configured to be rotatable using an independent power source or the power of an engine 5. .

And a base 1 provided at the front of the self-propelled vehicle 1
0 and the cover 8 of the transfer device 2 are connected and supported by a link 11 and a link 13 provided with a hydraulic cylinder 12, and the transfer device 2 is connected and supported by the expansion and contraction operation of the hydraulic cylinder 12. In order to enable rocking movement in the front and back direction about the fulcrum P, that is, to make the transfer device 2 parallel or inclined to the base 10 in plan view, and also to make the link 11 parallel to or inclined to the base 10 or the chassis 4. By interposing the hydraulic cylinder 14 between the links 11, it is configured to be movable to the left or right as the hydraulic cylinder 14 is extended or contracted.

On the other hand, the arm 15 extending from the base 10
is pivotally supported on a pin 16 installed horizontally on the chassis 4, and a hydraulic cylinder 17 is similarly interposed between the arm 15 and the chassis 4.
7, the transfer device 2 is configured to be able to move upward or downward via a link 11 and a link 13 provided with a hydraulic cylinder 12.

By the way, when this cleaning vehicle having the above configuration cleans the side of the road, first the self-propelled vehicle 1 is brought to the guardrail 18 side, and then the self-propelled vehicle 1 is moved toward the guardrail 18.
After operating the hydraulic cylinder 14 forward near the position of the pole 19 of 8, passing under the guardrail 18 and extending it to the side, the hydraulic cylinder 12
is activated so that the left end of the transfer device 2 is tilted backwards from the right end in plan view, and the hydraulic cylinder 17 is activated to lower the transfer device 2 downward, that is, the transfer device 2 is in the state shown by the imaginary line in FIG. 3. The hydraulic cylinder 12 is operated while the transfer body 9 of No. 2 is rotated to move the transfer device 2 from an inclined state to a parallel state and move it forward while performing cleaning work. When the pole 19 of the guardrail 18 is reached, the hydraulic cylinder 12 is actuated to move the transfer device 2 from the parallel state to the opposite inclined state, that is, the state shown by the solid line in FIG. After cleaning part side A, return the transfer device 2 to the parallel state again, move the transfer device 2 to the right to evacuate it from the guardrail 18, and after passing the pole 19 repeat the same operation as described above again to clean the guardrail 18 and its Continue the cleaning work on the end side of the pole 19.

This idea is a simple improvement in which a hydraulic cylinder is installed in at least one of the two links that connect and support the transfer device and the self-propelled vehicle, as described above, so that the transfer device can be moved from left to right as in the past. In addition to being able to move up and down, it is also possible to move parallel or inclined to the base in plan view, so that the end side of the road, which would otherwise be the uncleaned area when an obstacle such as a pole was on the side of the road, Now you can reduce it to a large extent.

Note that sensors 20, 21, 22, and 23 are provided in front, above, behind, and on the sides of the transfer device 2, respectively, and when these sensors 20 to 23 come into contact with an obstacle such as a pole 19, a signal is emitted. By interlocking the hydraulic cylinders 12, 14, and 17 to perform the required operations, it is easily possible to automatically perform the cleaning work on the end side of the guardrail 18 and its pole 19, and with this configuration. In addition to improving work efficiency, it can also be expected to prevent damage to the transfer device 2.

In addition, if a soil guide plate 24 is provided to guide the soil transferred from near the end of the transfer body 9 of the transfer device 2 to a part of the traveling device 3 that is not the tread surface (the center of the machine body), later soil collection work will be made more efficient. can be expected to increase.
