ている。[Problems to be solved by the invention] By the way, there are many places where rocks cannot be directly accessed by car, such as construction sites and rocky mountains. Therefore, the hose is usually extended to the rock crusher while the truck equipped with the air compressor is stopped on the road. Then, you can rest after interrupting the work, or when removing the rock crusher from the hose after the end of working hours and transporting it separately from the hose, extend your legs to a truck equipped with an air compressor, etc. The main switch of the air compressor is stopped by a method of calling out loud. However, since the air compressor is installed in a place away from the rock crusher, even if you go to a truck etc. by walking or contact a worker resident on a truck etc. However, there is a problem that the work completion cannot be smoothed, and unnecessary work is forced or time is uselessly cut, and the rock breaking work, which becomes heavy labor, is cut more sharply. In addition, if the wing nut that constitutes the tightening part of the connection part with the rock crusher in this type of rock crusher hose joint loosens and comes off due to vibration, etc., the hose is swayed by the jet pressure of compressed air, and the operator There is also a problem that the hose side connecting metal fittings may collide with rocks and be damaged, and an urgent solution is urgently needed.

It is possible to stop the blowout of compressed air from the free end of the hose at the rock breaking place without stopping the operation without waiting for the operation of the air compressor to be stopped. Therefore, it is not necessary to stop the operation switch of the air compressor far away from the rock crusher when the work is interrupted, when the working hours are over, when the rock crusher is removed from the hose for transportation, etc. This contributes to the relaxation of working conditions, which in turn improves the efficiency of rock breaking and reduces labor. Moreover, even if there is an accident such that the hose is gradually loosened due to vibrations during work and the hose is separated from the hose, there is a risk that a dangerous phenomenon may occur in which the hose is swung by the jet pressure of the compressed air jetted from the free end of the hose. In addition, it is possible to ensure the safety of the worker and prevent damage to the hose joint itself. Moreover, even if the valve element falls out of the valve shaft due to deterioration due to long-term use and does not function as a valve, the drop-out prevention protrusion remains in the recess formed in the nipple and remains in the valve shaft. Since it does not fall off, the cylindrical socket portion with the flange portion that is connected to the valve shaft portion does not fall off. Therefore, the flange portion of the cylindrical socket portion can be sandwiched between the connection screw pipe of the rock breaking machine and the base end portion of the nipple portion, and a hose joint for a rock breaking machine that is always airtight can be provided. Also, the machine end of the nipple
By the action of the steel ball and the rotary socket attached to the
After the wing nut is screwed into the rock crusher,
The nipple is rotatable and the wing nut is fastened to the rock crusher.
The rotary mechanism continues to function even after mounting, and the hose is twisted.
Workability is improved and the wing nut is crushed
The nipple does not rotate together when tightened on the machine.
In addition, connection work can be performed easily.

る。Next, the operation of the hose joint for a rock crusher of this embodiment will be briefly described. The connection screw pipe a of the rock crusher A is screwed into the female screw portion 21a of the wing nut 21 and the inside of the tip of the connection screw pipe a is screwed. While making the inclined surface a ′ of the peripheral surface and the tapered inclined surface 12b ′ of the outer peripheral surface of the flange portion 12b into surface engagement, the flange portion 12b
Is hermetically sandwiched between the connection screw tube a and the base end surface of the nipple portion 11 (specifically, the rotary socket 41). As a result, the valve body 32 at the tip of the valve shaft portion 22, which is continuously provided to the cylindrical socket portion 12, moves from the seating surface 11a at the tip surface of the nipple portion 11 to the hose 200.
The valves are separated inward and opened, and the air supply line 100 to the rock crusher A is opened (Fig. 1). On the other hand, when the connection between the connecting screw a of the rock breaking machine A and the wing nut 21 is artificially or naturally released, the rock breaking machine A holding the flange portion 12b therebetween.
Since the connection screw pipe a is eliminated, the valve body 32 is seated on the seating surface 11a and the valve is closed to automatically close the air supply line 100 (FIG. 3). Further, even if the valve body 32 falls out or is torn due to secular change due to permanent use, there is concern that the valve shaft portion 22 and the cylindrical socket portion 12 may fall out due to the action of the retaining protrusion 4. Since there is none, at least the connecting screw pipe a of the rock breaking machine A and the base end portion of the nipple portion 11 have a cylindrical socket portion 12
The hose joint for a rock crusher which can hold the flange 12b of the above and is always airtight. Reference numeral 6 is an O-ring.
