Description

WATER DISCHARGER FOR WATERING-VEHICLE}

The present invention relates to a waterproof tarpaulin for the sprinkler, and more particularly, to a sprinkler tarpaulin that can be operated by a hydraulic motor to accurately and stably control the waterproof direction and the waterproof distance or the waterproof height.

Generally, sprinkler trucks are used to clean roads, sidewalks, roadside trees, factories where dust is generated, or to supply or spray water therein. Such a water tank is basically equipped with a water tank filled with water to be injected or supplied. In addition, the spray car is provided with a spray means such as a spray towel, spray can, tarpaulin, spray hose, etc. to spray the water filled in the water tank to a predetermined position.

For example, as shown in FIG. 1, the tarpaulin 1 is mounted to the sprinkler 3 by the bracket 2. The tarpaulin 1 is connected to the water tank mounted on the sprinkler by a water pipe, and can also be selectively installed in front of or behind the sprinkler. Such a tarpaulin 1 includes a base 4 fixed to a bracket 2 at a predetermined position, a connecting portion 5 rotatably mounted left and right with respect to the base, and a connecting portion 5 thereof. It is rotatably mounted up and down and includes a waterproof part 6 for actually spraying water. On the other hand, the electric motor 7 is spoken to the connecting part 5 to rotate the connecting part 5 to the left and right, and the electric motor 8 to rotate the waterproof part up and down to the waterproof part 6. Or the handwheel is spoken.

On the other hand, the connection part 5 and the electric motor 7 are connected to each other by a worm and a worm wheel method, and similarly, the waterproof part 6 and the electric motor 8 or the manual handle are also worms and worm gears. Connected in a way.

According to this configuration, when watering or watering the water tank using the tarpaulin (1), if you want to change the direction of water and the direction of watering, the operator changes the watering direction by operating the electric motor or manual handle You can. That is, in the case of changing the water spray or waterproof direction, if the electric motor 7 or the manual handle is rotated in one direction or the other direction, the worm formed on the electric motor rotates and at the same time, the worm gear of the connecting portion 5 engaged with the worm By rotating in the left or right direction, it is possible to control the watering direction. On the other hand, if you want to adjust the water spraying distance by rotating the electric motor (8) or manual handle in one direction or the other direction by rotating the waterproof part 6 in the upward or downward direction, the waterproof distance and waterproof height It is adjustable.

However, it has been shown that such a tarpaulin installed in a conventional watering can cause a variety of problems. First, each electric motor addressed to the tarpaulin has a problem that can not control the direction and height of the tarpaulin accurately can not control the speed can only control the rotation direction.

In addition, since the driving of the motor is to be controlled instantaneously, a phenomenon of concentration of load may occur and a failure may be easily caused, and there is a problem in that electricity is consumed due to burnout of the motor.

Moreover, since the speed cannot be controlled, there is a problem in that the waterproof part is excessively rotated to the left, right, or rotated up and down outside the safety distance, resulting in damage to the device or the vehicle and injury to the operator.

The present invention is devised to solve the above problems, the object of the present invention is to provide a waterproof tarpaulin for a stable and accurate control of the controllable speed of the waterproof direction, waterproof position and waterproof distance of the tarpaulin.

Another object of the present invention is to provide a tarpaulin that can be prevented from failure and burnout and electrical consumption can be prevented.

In particular, one side of the connecting portion 16 is provided with a bracket 18 extending downward. The bracket 18 has two parts for detecting the range in which the connecting portion 16 is rotated or the left and right rotation directions by selectively contacting the reference piece 12 formed on the outside of the base 10. Proximity sensors 20 and 22 are installed.

On the other hand, the one end of the connecting portion 16 is formed with a through-hole 24 into which the worm of the hydraulic motor can be inserted for rotation of the waterproof portion to be described later. In addition, it is preferable that two proximity sensors 26 and 28 are installed at one end of the connection part 16 to detect rotation of the waterproof part to be described later or to detect a rotation direction of up and down.

In addition, the base 10 is provided with an actuator, that is, a hydraulic motor 30 for rotating the connecting portion 16 to the left and right. The hydraulic motor 30 is, of course, provided with a worm 32 rotatably inserted into the through hole of the base 10 so as to be engaged with the worm gear formed at one end of the connecting portion 16. The hydraulic motor 30 is connected with a hydraulic supply pipe 34 for operating the hydraulic motor. Of course, the hydraulic supply pipe 34 is connected to a hydraulic pump or hydraulic supply source (not shown) and receives hydraulic pressure therefrom.

The connecting portion 16 is also rotatably provided with a waterproofing portion 36 for actually waterproofing or watering the water. The waterproof portion 36 is rotatably installed up and down to adjust the waterproof distance or waterproof height. For such up and down rotation, a worm gear (not shown) is formed at an end portion of the waterproof part 36 inserted into the connection part 16. Particularly, the outer side of the waterproof part 36 includes a reaction part that reacts to the proximity sensors so that the proximity sensors 26 and 28 provided at the end of the connection part 16 can detect the rotation range of the waterproof part 36. 38, 40 are marked at a distance along the perimeter.

In addition, the connecting portion 16 is formed with an actuator, that is, a hydraulic motor 42 for rotating the waterproof portion 36 to the left and right. The hydraulic motor 42 is, of course, rotatably provided with a worm 44 inserted into the through hole 24 of the connecting portion 16 so as to be engaged with the worm gear formed at one end of the waterproof portion 16. The hydraulic motor 42 is, of course, connected with a hydraulic supply pipe 46 for operating the hydraulic motor. Of course, the hydraulic supply pipe 46 is connected to a hydraulic pump or hydraulic supply source (not shown) and receives hydraulic pressure therefrom.

Of course, each of the proximity sensor (20, 22; 26, 28) and each of the hydraulic motors (30, 42) of the tarpaulin according to the present invention is connected to the control panel 48 that can be installed at a predetermined position of the sprinkler have. Accordingly, the control panel 48 may not only control the waterproof and the waterproof amount, but also control the operation of each of the hydraulic motors 30 and 42 in accordance with a signal detected from each sensor, thereby controlling the waterproof direction in three dimensions. It is.

Hereinafter, the operation method and the mode of operation of the waterproofing tarpaulin according to the present invention will be described in detail.

First, when the operator initially operates the control panel 48 to waterproof the water using the tarpaulin, the water passes through the base 10 of the tarpaulin through a discharge pipe (not shown) connected to a water tank mounted on the sprinkler. Passing through the connection portion 16 is waterproof or sprayed to the outside through the waterproof portion 36.

During the waterproofing operation, if the operator wants to change the waterproof direction, adjust the waterproof distance, or adjust the waterproof direction and the waterproof distance at the same time, the hydraulic motors 30 and 42 by using the control panel 48. By selectively or simultaneously operating water can be waterproof in the desired direction.

That is, for example, in order to waterproof in the left direction, when the hydraulic motor 30 is rotated in one direction, the worm 32 installed in the hydraulic motor 30 is rotated, so that the connecting portion 16 is rotated in one direction, thereby The waterproof part 36 connected to the connection part 16 is rotated in the left direction so that the waterproof direction is changed. On the contrary, for example, when the hydraulic motor 30 is rotated in the other direction in order to change the waterproof direction to the right or the original position, the worm 32 installed in the hydraulic motor 30 is reversely rotated. By rotating in a different direction, the waterproof portion 36 connected to the connecting portion 16 is rotated to the right direction so that the waterproof direction is changed or returned to its original position.

In particular, when changing the waterproof direction of each of the left and right, the maximum rotation range of the direction is sensed or detected by the respective proximity sensor 20, 22 and transmitted to the control panel 48, for example, the connection portion 16 Alternatively, the waterproof part 36 may be prevented from being excessively rotated beyond the rotation range, thereby preventing inoperability of the tarpaulin and injury to the operator.

On the other hand, when adjusting the waterproof distance or waterproof height, the operator rotates the hydraulic motor 42 by selectively supplying the hydraulic pressure through the supply pipe 46 using the control panel 48. For example, when the waterproof distance is far away or the waterproof height is increased, the worm 44 connected to the hydraulic motor 42 is rotated in one direction to raise the waterproof part 36 upward, thereby preventing the waterproof distance or being waterproof. You can raise the height. On the contrary, when the waterproof distance is increased or the waterproof height is increased, by rotating the worm 44 connected to the hydraulic motor 42 in the opposite direction, the waterproof part 36 is lowered downward, thereby making the waterproof distance close or waterproof. You can lower the height.

Of course, when the waterproof distance or the waterproof height of the waterproof part 36 is changed, the maximum rotation range in the direction is detected by each proximity sensor 26 and 28 in response to each reaction part 38 and 40. By being detected and transmitted to the control panel 48, for example, the waterproof portion 36 can be prevented from being excessively rotated beyond the rotation range, thereby preventing the control of the tarpaulin and injuries of the operator.

On the other hand, the waterproof direction and the distance or height can be controlled at the same time, that is, the operator or driver using the control panel 48 to rotate each hydraulic motor (30, 42) in the direction desired by the operator waterproof portion 36 By changing the direction of), you can control the waterproof distance and waterproof height in three dimensions.

In particular, the waterproof direction and the waterproof distance or the waterproof height of such a tarpaulin is controlled by the driving of the hydraulic motor using the hydraulic pressure as the operating source, it is possible to smooth and flexible all rotational driving and control. In addition, by the irregular supply of power, the failure caused by the burnout and overload of the motor can be prevented to accurately control the tarpaulin.

As a result, according to the waterproof tarpaulin for the sprinkler according to the present invention, by using a hydraulic motor using the hydraulic pressure as the power source, it is possible to control the speed stably and accurately during the control of the waterproof direction and waterproof distance, and also to prevent failure and burnout It works.

Although a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and variations can be made without departing from the scope of the appended claims.
