Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaner device for removing deposits on a belt of a belt conveyor.

[0002]

2. Description of the Related Art In a belt conveyor in which a belt is spanned between a plurality of pulleys and the belt is moved to convey a transported material such as earth and sand, the adhered matter adhering to the surface of the belt causes the belt to return. There was a problem of falling on the road and polluting the surrounding area.

[0003]

SUMMARY OF THE INVENTION It is a technical object of the present invention to solve the above-mentioned problems and to provide a cleaner device capable of preventing the surroundings from being contaminated by deposits on the belt. There is.

[0004]

In order to solve the above-mentioned problems, in the first invention, in a belt cleaner device of a belt conveyor which conveys an article by moving a belt on the head pulley, An injection pipe extending in the width direction of the belt is rotatably provided at the lower outer periphery, and a fluid injection nozzle for injecting a fluid is provided at one end of the injection pipe, and a spiral blade is fixed inside the injection pipe. In addition, a structure is adopted in which the injection pipe is formed with an injection hole for allowing the fluid injected inside from the fluid injection nozzle to flow out to the outer periphery of the injection pipe.

According to the second aspect of the invention, in a belt cleaner device of a belt conveyor for transporting an article by moving the belt on the head pulley, an injection pipe extending in the width direction of the belt is provided under the outer periphery of the head pulley. It is rotatably provided, and at both ends of the injection pipe, fluid injection nozzles for injecting fluid into the injection pipe are provided, and a partition plate is fixed to the central portion in the axial direction inside the injection pipe. Adopting a configuration in which spiral blades in the opposite direction are attached, and an injection hole is formed in the injection pipe so that the fluid injected inside from each fluid injection nozzle flows out to the outer periphery of the injection pipe.

Here, air, water, cleaning water or the like can be used as the fluid to be injected into the injection pipe.

[0007]

In the first aspect of the invention, when a fluid is jetted from the fluid jet nozzle to the inside of the jet pipe, the fluid flows along the spiral blade, flows out from the jet hole and flows along the spiral blade. And the reaction of the fluid flowing out from the injection hole causes the injection pipe to rotate in one direction.

Therefore, the fluid flowing out from the injection hole to the outer periphery of the injection pipe rotates around the injection pipe and collides with the belt during the rotation to wash the belt and remove the adhered matter on the belt. it can.

As in the case of the second invention, by injecting the fluid from both ends of the injection pipe to the inside, the length of the injection pipe is the same as in the case of injecting the fluid from one end of the injection pipe to the inside. In this case, the velocity of the fluid flowing inside the injection pipe is less decreased, the ejection velocity of the fluid flowing out from the injection hole can be increased, and the belt can be effectively cleaned.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a belt 2 is wound around the head pulley 1, and the transported material A conveyed by the movement of the belt 2 is discharged from the front of the head pulley 1.

An injection pipe 3 is provided below the outer periphery of the head pulley 1. The jet pipe 3 extends in the width direction of the belt 2, and a fluid jet nozzle 4 is inserted into one end of the jet pipe 3 as shown in FIG. 2, and the jet pipe 3 is rotatably supported around the fluid jet nozzle 4. Has been done.

Here, as the fluid ejected from the fluid ejecting nozzle 4, air, water, cleaning water or the like is used.

A spiral blade 5 is attached inside the injection pipe 3. Further, the injection pipe 3 is provided with a large number of injection holes 6 in the axial direction and the circumferential direction. As shown in FIG. 2, the injection hole 5 may be formed of a slit extending in the axial direction, or the slit may be inclined with respect to the axial direction. It may also be composed of small holes.

Now, from the fluid jet nozzle 4 to the jet pipe 3
When a fluid is injected into the inside of the jet, the fluid flows along the spiral blade 5, and when the inside of the jet pipe 3 is filled with the fluid,
It flows out of each injection hole 6 toward the outside of the injection pipe 3.

At the time of jetting the fluid as described above, the jet pipe 3 rotates in one direction by the flow of the fluid flowing along the spiral blades 5 and the reaction of the fluid flowing out from the jet holes 6.

Therefore, the fluid flowing out from each injection hole 6 rotates around the injection pipe 3, collides with the belt 2 during the rotation, and the collision position changes in the longitudinal direction of the belt 2, The deposit can be removed by cleaning the surface of No. 2.

FIG. 4 shows a second embodiment of the present invention.
In this embodiment, a partition plate 8 is fixed to the central portion in the lengthwise direction inside the jet pipe 3 arranged below the outer periphery of the head pulley 1, and a pair of spiral blades 5a opposite to each other are provided on both sides of the partition plate 8. 5b are arranged and fixed to the injection pipe 3, and a large number of injection holes 6 are formed in the injection pipe 3.

Further, the tip end portions of the fluid jet nozzles 4a and 4b are inserted inside the both end portions of the jet pipe 3, and the jet pipe 3 is rotatably supported around the respective fluid jet nozzles 4a and 4b.

As described above, the spiral blades 5a, 5 in the opposite direction
By providing a pair of fluid injection nozzles 4a and 4b at both ends of the injection pipe 3 having b, the injection pipe 3 is provided with a fluid injection nozzle 4 at one end, as compared with the embodiment of FIG. When the lengths are the same, the decrease in the velocity of the fluid injected into the injection pipe 3 is small, and the injection velocity of the fluid flowing out from the injection hole 6 can be increased.

Therefore, the injection pipe 3 can be rotated at a high speed, and the belt 2 can be cleaned very effectively.

[0022]

Since the present invention is constructed as described above,
It has the following effects.

In the belt cleaner device according to the first aspect, when the fluid is jetted from the fluid jet nozzle into the jet pipe, the fluid flows along the spiral blade and flows out from the jet hole, and the fluid is discharged to the spiral blade. Since the injection pipe rotates due to the movement along it and the reaction caused by the injection of the fluid flowing out of the injection hole, the surface of the belt is cleaned by the collision of the fluid flowing out of the injection hole, and the deposits are removed by the cleaning. Therefore, in the return path of the belt, it is possible to prevent the surrounding flow due to the fall of the adhered matter.

Further, since the injection pipe rotates, the collision range of the fluid flowing out from the injection hole with respect to the belt can be made long, so that the deposit can be effectively removed.

Furthermore, since the jet pipe is rotated by utilizing the fluid flowing out from the fluid jet nozzle, it is not necessary to separately provide a rotating device for rotating the jet pipe, and the device can be downsized and the cost can be reduced. An easy-to-use cleaner device can be provided.

In the belt cleaner device according to the second aspect, the fluid jet nozzles are provided at both ends of the jet pipe having the spiral blades in the opposite directions, and the fluid is jetted from each nozzle into the jet pipe. The pipe can be rotated at a high speed, the injection speed of the fluid flowing out from the injection hole can be improved, and the belt can be cleaned more effectively.
