7 is a hydraulic circuit diagram applied to the present invention, the hydraulic pressure from the hydraulic pump 71 controls the hydraulic cylinder 11 for the up and down movement of the first frame 9 via the relief valve 73. The structure which can move to the 1st solenoid valve 75 and the 2nd solenoid valve 77 which controls the hydraulic motor 77 is shown. That is, in the hydraulic circuit of the present invention, the relief valve 73 and the first solenoid valve 75 are connected to the hydraulic pipe, and the hydraulic pressure discharged from or passed through the first solenoid valve 75 is transmitted to the second solenoid valve 77. Has a structure that can be supplied. Therefore, the hydraulic cylinder 11 may be driven even during the operation of the hydraulic motor 43 to implement the up and down movement of the first frame 9. In addition, when an overload occurs on the contact surface when the brush member 45 rotates, the hydraulic pressure may be returned through the relief valve 73 to protect the equipment. Preferably, the first and second solenoid valves 75 and 77 are connected to separate operation buttons so as to be operated from the driver's seat of the vehicle.

In addition, the hydraulic motor 19 for driving the mount 23 to move horizontally to the left and right may have a structure that can be driven by a conventional separate hydraulic circuit.

The operation of the central separator of the road or the fan cleaning device made in this way will be described in more detail as follows.

First, when an operator in a vehicle operates a switch for driving the first solenoid valve 75 (not shown), the hydraulic pressure supplied by the hydraulic pump 71 passes through the relief valve 73 to the first solenoid valve 75. ) To drive the hydraulic cylinder (11). Then, since the first frame 9 is coupled in a parallelogram structure by the links 5 and 9, the first frame 9 is raised or lowered while maintaining the horizontal state. The position of the first frame 9 is determined, and a switch (not shown) is operated to operate the hydraulic motor 19 connected to a separate hydraulic circuit. Then, the power transmission member made of the rotary screw 21 rotates in accordance with the rotation of the hydraulic motor 19 to horizontally move the mount 23 to the left or right. At this time, the mount 23 moves along the guide members 13 and 15. 1 illustrates a state for cleaning a pan disposed on the left side when viewed from the front of the vehicle, and FIG. 3 illustrates an example of cleaning the upper surface of the center separator disposed on the right side when viewed from the front of the vehicle. As the mount 23 is disposed on the left or the right side, the side and the upper surface of the central separator or the safety pan, the protective wall, etc. can be cleaned regardless of the driving direction of the vehicle.

Subsequently, the second frame 25, which is rotatably coupled to the mount 23 horizontally, is disposed at a predetermined position, and then the first frame 9 and the second frame 25 are fixed to the fixing member 27. Fix it. Of course, in another embodiment, when the fixing member 27 is formed of an actuator such as a hydraulic cylinder, the horizontal position of the second frame 25 may be automatically adjusted by a general hydraulic driving circuit. In this case, the tip of the second frame 25 can be fixed at any position on the circumference, thereby increasing the degree of freedom.

When the second frame 25 is fixed in this way, the distance and height adjustment link 29 is adjusted so that the horizontal plane is rotated in the vertical direction with respect to the horizontal plane. That is, when the bolts 37 are rotated in one direction, the surfaces on which the first and second members 31 and 33 and the bars 35 and bar are fixed are separated from each other by the spring 39. At this time, when the bar 35 is placed horizontally, the height is lowered, and when the bar 35 is disposed close to the vertical position, the bar 35 can be cleaned at a high position, that is, the upper surface of the central separator. When the proper position is set, the operator rotates the bolt 37 again in one direction so that one surface of the first and second members 31 and 33 and the bar 35 are brought into close contact with each other and the threads 31a, 33a, and 35a are bitten together. To do that. Of course, the direction of the third frame 41 is adjusted by adjusting toward the second member 33 so that the brush member 45 may be disposed horizontally or vertically.

And when the operator operates the switch (not shown) to operate the second solenoid valve 77 to drive the hydraulic motor 43, the brush member 45 is rotated while the hydraulic motor 43 is rotated. In this case, when the brush member 45 is horizontally disposed, the upper surface of the central separator may be cleaned, and when the brush member 45 is vertically disposed, the side of the central separator, the side of a safety fence, or the side of a firewall such as a highway. Can be cleaned.

Subsequently, if the operator operates a switch (not shown) to spray water or the cleaning liquid with the spray nozzle for spraying the cleaning liquid, water or the cleaning liquid is sprayed onto the brush member 45 or the cleaning object to remove the foreign matter adhering to the cleaning object. It can be.

On the other hand, when the operator manipulates the first solenoid valve 75 to operate when the height of the object to be cleaned is changed during the cleaning operation as described above, the hydraulic pressure is maintained even while the hydraulic motor 43 for rotating the brush member 45 is operated. The cylinder 11 is driven to adjust the height of the first frame 9, which makes the operation very convenient.

As described above, the central separator or pan cleaning apparatus of the present invention is not only a side and top surface of the central separator of the road, a safety fan having a large number of spaces, a firewall installed on a highway, a concrete central separator, etc., but also a place requiring cleaning work. It can be applied in various ways.

As such, the present invention provides a center separator or a pan cleaning device having a mechanical structure capable of moving a brush member that is rotated by a hydraulic actuator and a third frame in which the brush members are coupled to the upper, lower, left, and right sides. By providing a technology that can be mounted on the vehicle, there is an effect that can effectively remove the foreign matter adhering to the side, the upper surface of the road, the safety fan, the security barrier, and the like.

In addition, the present invention has the effect of providing a structure for cleaning the cleaning object disposed on the left or right side regardless of the traveling direction of the vehicle to promote the safety of the operator in the working vehicle.

In addition, the present invention has the effect of reducing the traffic jam by reducing the cleaning time by quickly removing the foreign matter attached to the side or the upper surface of the central separator, a fan or a firewall.
