The controller 80 is formed in the form of a box, and the controller 80 is provided with a plurality of joystick-type adjusting devices 82 to adjust the various devices described above. A necklace 83 is provided to adjust.

In FIG. 3, reference numeral 92 denotes a support member for supporting the external suction hose 40 that is flexible and long.

Referring to the operation of the cleaning vehicle employing the external suction hose control device according to the present invention having the configuration as described above are as follows.

Referring back to the drawings, it is preferable that the cleaning vehicle employing the external suction hose control device according to the present invention, for example, is mounted to the rear of the road cleaning vehicle as shown in FIG. The reason is that a control box 22a, a hydraulic drive pump 20, an upper engine 19, a turbo blower 1, a sludge stack 24, etc., which are basically installed in a road cleaning vehicle, can be used together. Because it can.

However, the cleaning vehicle employing the external suction hose control device according to the present invention does not necessarily have to be mounted on the road cleaning vehicle as shown in FIG. 1, and uses only the external suction hose 40 to use the external suction hose 40. That is, it is possible to manufacture a cleaning vehicle used only for the purpose of cleaning the sewer manhole on the roadside and the dirt and rubbish in the corners where it is difficult to enter the vehicle to be stacked on the sludge stacking unit 24.

This is explained in more detail.

The general road surface cleaning is performed by the road surface cleaning vehicle as shown in FIG. 1, and the operator uses the controller 80 to clean the sewer manhole on the side of the road, which is impossible to clean with the road surface cleaning vehicle, or the corner where it is difficult to enter the road surface cleaning vehicle. The external suction hose 40 is positioned at the position to be cleaned, and the turbo blower 1 is operated to suck garbage through the external suction hose 40 to be loaded on the sludge loading part 24.

That is, by using the controller 80, the front and rear positions of the external suction hose 40 is adjusted by the forward and backward cylinder 50, the left and right positions adjust the left and right moving device 60, for example, the external suction hose ( The distance between 40 and the road surface (or ground) to be cleaned may be adjusted by the elevating device 70.

At this time, the front and rear positions of the external suction hose 40 can be easily adjusted by the forward and backward cylinder 50, in particular, the forward and backward cylinder 50 is two side by side at a predetermined interval to move the left and right moving device (60) ) And the elevating device 70 can be stably supported.

And the left and right moving device 60 can easily adjust the left and right positions of the elevating device 70 to which the external suction hose 40 is fastened by interlocking the rack member 61 and the pinion device 62, in particular the rack member Guide rollers 63 are provided at the upper and lower portions of the 61 to smoothly move the external suction hose 40 to the left and right. In addition, since the sensors 64 are respectively provided at both ends of the rack member 61 of the left and right moving apparatus 60, the left and right operating range of the elevating apparatus 70 is limited to the rack member. Therefore, the lifting device 70 from the rack member 61 is prevented from falling or malfunction occurs.

In addition, since the external suction hose 40 is raised and lowered by the guide block 74 such as an L guide, the engaging protrusion 75 and the elevating cylinder 76, the elevating device 70 smoothly lifts and lowers the external suction hose 40. In particular, two hose fastening members 73 for fastening the external suction hose 40 on the rear surface of the elevating member 72 are provided at regular intervals so that the movable range of the external suction hose 40 can be improved. You can widen it.

In addition, one side of the forward and backward cylinder 50 is provided with a hydraulic control valve 91 that can adjust the degree of hydraulic pressure provided to each device can adjust the working speed. That is, since the operating speed of each device can be adjusted according to the opening and closing amount of the hydraulic control valve 91, for example, when the amount of garbage sucked into the external suction hose 40 is large, the opening of the hydraulic control valve 91 is performed. The operation speed of each device is reduced by reducing the accuracy, and when the amount of waste is small, the operation speed of each device is increased by increasing the opening degree of the hydraulic control valve 91.

In addition, the operator can be connected to the control box (22a) to the controller (80) to the neck using a necklace 83 to control each of the above devices, a plurality of adjusting devices 82 are provided in the form of a joystick Therefore, the cleaning operation can be carried out conveniently.

And the controller 80 is provided with an alarm device 81 can block the access of other vehicles or people during the cleaning operation may cause a safety accident in advance.

As described above, the cleaning vehicle employing the external suction hose control device according to the present invention has the following effects.

It is not possible to clean the road cleaning vehicle, i.e., to clean the sewer manhole on the side of the road or to clean the dirt and dust in the corner where it is difficult to enter the road cleaning vehicle. You can adjust the position with.

Therefore, it is possible to prevent fatigue or disease caused by the worker holding the external suction hose by hand and to avoid the worker's work avoidance, and to improve the work efficiency because the work can be performed quickly and cleanly.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
