Description

TECHNICAL FIELD The present invention relates to a sprinkler for a crusher mounted on a construction machine, a work vehicle, or the like.

2. Description of the Related Art FIG. 3 is a side view showing a state in which a hydraulic shovel equipped with a crusher 1 is performing a crushing operation. The crusher 1 is attached to the tip of the work attachment 2 of the hydraulic shovel,
Crushes buildings and other structures.

Since a large amount of dust is generated during the crushing operation, the worker sprays water on the crushing portion with a watering hose (not shown) or attaches a hose to the work attachment 2 to spray water around the crusher 1. To prevent problems such as dust pollution.

Problems to be Solved by the Invention At the time of the crushing operation by the crusher, one worker had a hose for watering as a conventional watering means. For that purpose, a worker for watering is required, and the worker uses a nozzle of a considerably large diameter hose and pulls the hose around the crushing machine that moves one after another, while spraying water to the watering point. I was Workers were tired and dusted at the same time, which was a problem in terms of safety and health.

The present invention solves the above-mentioned problem, and aims to provide a watering apparatus that can eliminate watering workers and can automatically follow a location where a crusher performs crushing and perform watering. I do.

Means for Solving the Problems The means of this invention taken to solve the above problems are as follows. Attach a transmission sensor to the crusher attached to the tip of the work attachment. On the other hand, a hose for watering is installed around the construction machine,
The base of the hose is connected to a water supply source via a water discharge pressure adjusting unit, the nozzle is connected to the tip of the hose, the nozzle is attached to the nozzle direction angle drive unit, and the nozzle is provided with a reception sensor. . The receiving sensor receives the signal from the transmitting sensor, and the controller outputs the received signal to the nozzle direction angle driving unit and the water discharge pressure adjusting unit from the controller.

Action b. The crusher attached to the tip of the work attachment is equipped with a transmission sensor that can emit or transmit, for example, laser light or ultrasonic waves. Therefore, a signal from the transmission sensor is received by a reception sensor provided in the nozzle, and the signal is input to the controller.

B. The controller determines the relative distance and direction between the transmission sensor and the reception sensor based on the input signal, and outputs a command signal to the nozzle direction angle drive unit and the water discharge pressure adjustment unit. Thereby, the nozzle direction angle drive unit and the water discharge pressure adjusting unit can be adjusted and operated to a required watering state.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing a sprinkler according to the present invention. In the figure, 1 'is a crusher, 2 is a work attachment, 3 is a transmission sensor provided on the crusher 1', 4 is a hose for watering, 5 is a water discharge pressurizing and adjusting section equipped with a compressor, etc., 6 is a tap water etc. A water supply source, 7 is a nozzle, 8 is a nozzle direction angle drive unit having a control motor and the like, 9 is an arm of the nozzle direction angle drive unit 8, 10 is a reception sensor provided on the nozzle 7, and 11 is a controller. FIG. 2 is a block diagram showing functions of the controller 11.

Next, the structure of the sprinkler according to the present invention will be described with reference to FIGS. 1 and 2. FIG. The transmission sensor 3 is attached to the crusher 1 ′ mounted on the tip of the work attachment 2, while a hose 4 for watering is arranged around the hydraulic shovel, and the base of the hose 4 is adjusted to discharge pressure. A nozzle 7 is connected to a water supply source 6 via a part 5, and a nozzle 7 is connected to a tip of the hose 4. The nozzle 7 is attached to an arm 9 of a nozzle direction angle drive unit 8, and a reception sensor 10 is provided for the nozzle 7. The reception sensor 10 receives the signal from the transmission sensor 3, inputs the received signal to the controller 11, and issues a command to the nozzle direction angle drive unit 8 and the water discharge pressure adjustment unit 5 from the controller 11. It was configured to output a signal.

Next, the function of the watering device according to the present invention will be described. The crusher 1 'attached to the tip of the work attachment 2 is provided with a transmission sensor 3 capable of emitting or transmitting, for example, laser light or ultrasonic waves.
Therefore, the signal from the transmission sensor 3 is received by the reception sensor 10 provided in the nozzle 4, and the signal is input to the controller 11. Based on the input signal, the controller 11
The relative distance and direction between the transmission sensor 3 and the reception sensor 10 are determined, and a command signal is output to the nozzle direction angle drive unit 8 and the water discharge pressure adjustment unit 5. Thereby, the nozzle direction angle drive unit 8 and the water discharge pressure adjusting unit 5 can be operated to adjust to a required water spray state. Therefore, in the water sprinkling device of this invention, water can be sprinkled by automatically following the place where the crusher 1 'crushes.

Note that the controller 1 of the sprinklers
1, the water discharge pressure adjusting unit 5 and the like may be mounted on a construction machine, or the whole sprinkler may be provided independently of the construction machine.

Effect of the Invention At the time of the crushing operation by the crusher, one worker had a hose for watering as a means of watering in the prior art. For this purpose, a worker for watering is required, and the worker uses a considerably large-diameter hose nozzle to pull the hose around the crusher, which is moving one after another, while spraying water to the watering point. I was Workers were tired and dusted at the same time, which was a problem in terms of safety and health.

However, in the sprinkler according to the present invention, a transmission sensor is attached to the crusher, the base of the sprinkling hose is connected to the water supply source through the water discharge pressure adjusting unit, and the nozzle is connected to the tip of the hose. The nozzle is attached to the nozzle direction angle drive unit, and a receiving sensor is provided for the nozzle. The receiving sensor receives a signal from the transmitting sensor and inputs the signal to the controller. The controller determines the relative distance and direction between the transmission sensor and the reception sensor based on the input signal, and outputs a command signal to the nozzle direction angle drive unit and the water discharge pressure adjustment unit. Thereby, the nozzle direction angle drive unit and the water discharge pressure adjusting unit can be adjusted and operated to a required watering state.

Therefore, in a construction machine, a work vehicle, or the like provided with the water sprinkling device according to the present invention, a water sprinkling operator is not required, and water can be sprinkled automatically by following the place where the crusher performs crushing.
