In addition, a predetermined inlet pipe 90 is connected to the drain pipe 20 between the auto valve 21 and the spray pump 30 by a branch, and an opening / closing valve 91 is installed in the inlet pipe 90 to provide a controller. It is preferable to open and close according to the control signal of 120 to store the water sucked from the outside along the passage of the water inlet pipe 90 to the spray tank 10 through the return pipe 40. The water inlet pipe 90 is intended to be used for a variety of purposes, such as for removing snow from the snow removal vehicle as well as pumping out the water in the puddle or supplying water during natural disasters.

In addition, by installing a flow meter (17) on the inner top of the spray tank 10 to detect when the aqueous solution is filled in the spray tank 10, and then displayed through the full water display means 19 under the control of the controller 120 It is configured to sound an alarm, and also by installing a water supply pipe 15 on the top of the spray tank 10 by interconnecting with an external storage tank (not shown) in which the snow removal aqueous solution is stored, Received and supplied is configured to store in the spray tank (10).

Looking at the operation of the snow removal vehicle configured as described above is as follows.

First, the water supply pipe 15 installed on the upper end of the spray tank 10 of the snow removal vehicle is connected to an external aqueous solution storage tank (not shown) through a predetermined hose to receive and receive an aqueous snow removal solution from the storage tank.

When the aqueous solution is filled in the spray tank 10 is detected by the flow meter 17, in accordance with the output signal of the flow meter 17, the controller 120 displays a display device or a warning light (19) indicating the state of full water It works.

When operating in the stirring mode through the operating panel 110 installed in the driver's seat while the aqueous solution is stored in the spray tank 10 in this way, the controller 120 opens the autovalve 21 and the automatic control valve 41 ( Open and each injection valve (51, 53, 55) is closed (Close) to operate the spray pump (30). Since the spraying pump 30 is the most important device for spraying snow removal agent, it is preferable to install a plurality of spraying pumps 30 in parallel as shown in case of failure.

Accordingly, the aqueous solution stored in the spray tank 10 is sucked through the '┍'-shaped drain pipe 20 located in the groove 13 (Sump) and returned via the auto valve 21 and the spray pump 30. It is returned to the spray tank 10 through, the aqueous solution returned to the spray tank 10 is injected through the injection hole of the stirring pipe 12, the aqueous solution stored in the spray tank 10 is stirred again by the vortex action of water Maintaining a uniform concentration. Producing the drain pipe 20 in a '┍' shape prevents a phenomenon in which the inlet of the drain pipe 20 is clogged due to solidification of the snow removing agent or the snow removing agent in the aqueous solution, and pumping of the aqueous solution in the groove 13 is also performed. To make it possible.

When the snow removal mode is selected through the operation panel 110 after completing the stirring operation, the controller 120 opens the auto valve 21 and the respective injection valves 51, 53, and 55 and automatically controls them. The valve 41 closes and then operates the spraying pump 30.

According to the operation of the spraying pump 30, the aqueous solution stored in the spraying tank 10 is sucked through the '자' shaped drainage pipe 20 located in the groove 13 to pass through the auto valve 21 and the spraying pump 30. Flows to the first to third injection valves 51, 53, and 55 of the injection means 50.

The aqueous solution flowing through the first to third injection valves 51, 53, and 55 is connected to the respective injection pipes 71, 73, and 75 through the ground, left side, and right side injection pipes 71, 73, and 75; (81, 83, 85) to be sprayed to the ground and side.

However, the injection pressure output through the injection nozzles (81, 83, 85) in the snow removal mode depends on the amount of the aqueous solution stored in the spray tank 10, which is installed on the discharge pipe 35 side of the spray pump (30) The pressure gauge 33 detects the discharge pressure and displays the measured pressure on the pressure display unit 130 installed in the driver's seat. When the detected pressure is higher than the set value, the controller 120 proportionally adjusts the automatic control valve 41. As the control is opened by a certain amount, the injection pressure is lowered. When the automatic control valve 41 is opened, some of the aqueous solution via the spray pump 30 is returned to the spray tank 10 through the return pipe 40.

Of course, when the pressure detected by the pressure gauge 33 is lower than the set value, the automatic control valve 41 is closed to close the passage of the return pipe 40.

In addition, the nozzles 81, which are installed on the ground, left and right sides of the first to third injection valves 51, 53, and 55 are selectively operated by using the operation panel 110 installed in the driver's seat according to the situation. Naturally, it is possible to selectively operate 83, 85).

In addition, the injection pipes 73 and 75 provided with the left and right injection nozzles 83 and 85 are formed in a curved line having a substantially ')' shape rather than a straight shape, and thus the injection angles of the injection nozzles 83 and 85 are different. The left and right side injection pipes 73 and 75 are made of a lap joint which is different from each other and the injection pipe support members 74 and 76 supporting the injection pipes 73 and 75 are double-adjustable. It can also be adjusted in the direction, allowing more freedom in adjusting the spray angle.

The agitation mode and the snow removal mode have been described, but a switch for designating and instructing the agitation mode and the snow removal mode on the operation panel 110 is installed, and the controller 120 automatically controls each valve by a control program according to each mode. It may also be, but it is natural that each valve can be individually controlled by providing a switch for operating each valve separately on the operation panel (110).

On the other hand, if you want to use the vehicle to inhale and store water instead of snow removal, the auto valve 21 and each injection valve (51, 53, 55) is closed and the on-off valve 91 and automatic control When the spray pump 30 is operated while the valve 41 is opened, the water sucked through the water inlet pipe 90 passes through the opening / closing valve 91, the spray pump 30, the return pipe 40, and the automatic control valve. It is to be transmitted to and stored in the spray tank 10 via 41.

Although a specific embodiment of the present invention has been described and illustrated above, the auto valve, the return valve and the injection valve are not automatically controlled by using a controller, but variously installed by a person skilled in the art, such as a manual valve installed by a user manually opening and closing. It is obvious that it may be modified. Such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, but should fall within the claims appended to the present invention.

Therefore, in the present invention, it is possible to increase the stirring performance of the snow removal solution by the self-stirring of the water and the snow removal agent injected from the outside, and the injection pressure is adjustable when the snow removal solution is injected, the reliability of the injection distance and snow removal area is excellent. In addition, by controlling the injection angle of the side nozzles, the snow removal area can be extended to the neighboring lanes in one operation, and the operation and work efficiency can be greatly improved by automating all operations such as stirring and spraying. have.
