As an example of the prior art watering means to be performed at the time of crushing work, an operator uses a water discharge nozzle at the tip of a water supply hose to spray water around a crushing machine which moves one after another. Was. The worker who sprays water is necessary, and since the worker who sprays water is not only tired but also wears dust, it cannot be said that safety and health are perfect. An object of the present invention is to provide a watering device for a crusher that can solve the above problems.

[0004]

A crusher is attached to the tip of a work attachment of a construction machine in order to disassemble a building or the like, and dust generated during the crushing work of the crusher is removed from the inside of the body of the construction machine. Or a sprinkler device for sprinkling water from a water supply source provided outside, a swivel joint for supplying hydraulic pressure to a crushing cylinder disposed in the center of the slewing bearing of the crusher, A water supply passage hole opened inside the swivel joint, and a sprinkling nozzle integrally attached to the swivel joint at a downstream end of the water supply passage hole, for supplying water from the water supply source to the water supply hole Water was sprayed from the inside of the crusher to the periphery of the crusher rocker beam through the passage hole and the watering nozzle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a hydraulic excavator equipped with the water sprinkling device of the present invention. In the figure, 1 'is a crusher,
2 'is a work attachment, 11 is a lower traveling body, 12 is an upper revolving body, 13 is a driver's cab, 14 is a water supply tank mounted on the upper revolving body 12, 15 is a water supply pump, 16 is a driving device for the water supply pump 15, Reference numeral 17 denotes a stop valve, reference numeral 18 denotes a water supply pipe, reference numeral 19 denotes a swivel joint provided at the center of the slewing bearing 6 of the crusher 1 ', and reference numeral 20 denotes a water spray nozzle attached to the lower end of the swivel joint 19. FIG.
Fig. 2 is a partially cutaway side view of the crusher 1 'in Fig. 1. In the figure, the same reference numerals are given to components using the same components as the conventional technology. 21 is a turning motor.
FIG. 3 is a detailed view of a portion A in FIG. In the figure, reference numeral 22 denotes a water supply passage hole.

Next, the structure of the sprinkler according to the present invention will be described with reference to FIGS. A water supply passage hole 22 passing through the inside of the swivel joint 19 is formed in the swivel joint 19 disposed at the center of the slewing bearing 6 of the crusher 1 ′, and water is sprayed on a downstream end of the water supply passage hole 22. A nozzle 20 is provided, and water from a water supply source (referred to as a water supply tank 14 or a water supply source outside the upper revolving unit 12) is directed from the inside of the crusher 1 ′ to the periphery of the rocker beam 8 through the water supply passage hole 22 and the watering nozzle 20. And sprinkled it. Further, an operation unit of a stop valve 17 for operating start and stop of watering (not shown, but refers to a handle, a lever, and the like for opening and closing the stop valve 17) is arranged inside the cab 13.

Next, the operation of the sprinkler according to the present invention will be described. When performing the crushing operation by the crusher 1 ', the driver opens the stop valve 17 as necessary.
The water in the water supply tank 14 (water supply source) is discharged from the water supply pump 15, the opening passage of the stop valve 17, the water supply pipe 18, the water supply passage hole 22 inside the swivel joint 19,
Water is sprayed toward the tip side of the rocker beam 8 via the water spray nozzle 20. That is, since the water from the water supply source is discharged from the watering nozzle 20 attached to the swivel joint 19, watering can be performed by automatically following the location where the crusher 1 'crushes. In addition, the start and stop of watering can be determined by the driver in the cab 13, which is very convenient.

[0008]

[Effects of the Invention] According to the watering device for the crusher of the present invention,
While the crusher can be pivoted with respect to the work attachment, the water discharged from the watering nozzle automatically follows the crushing portion of the crusher to perform reliable watering. In addition, since the operation unit of the stop valve for operating the start and stop of watering is disposed in the cab, it is very convenient because the driver can be in the cab, determine and operate as needed. Therefore, in the construction machine and the work vehicle equipped with the water sprinkling device of the present invention, it is possible to exert sufficient effects on labor saving and prevention of dust generation during crushing work.
