2 to 7, the belt conveyor 100 according to the present embodiment includes a belt 20, a hydraulic pressure providing unit 30 for providing hydraulic pressure to the belt 20, and a belt 20 and a hydraulic pressure providing unit. It may be configured to include a frame 11 for supporting the (30).

The belt 20 is formed in a continuous ring shape to enable the crawler movement. Then, the belt 20 is transferred to the transport (T) to be transported by lifting the transport (M) supplied from the chute for charging (S of FIG. 1), and transport the transport (M) to a desired position after The return unit R may be divided.

Here, the transfer part (T) is formed as a concave curved surface as shown in Figure 5, as the transport (M) is seated on its upper surface. Therefore, the conveying part T is conveyed with the cross section forming a curve.

On the other hand, since only the belt 20 is transported without the transport M, the return part R is transported in a state in which the cross section forms a straight line.

This, the crawler movement of the belt 20 can be made by the belt driving means (5). Belt drive means 5 may be configured to include a motor (motor, not shown) and the like.

The hydraulic pressure providing unit 30 provides a pressure by fluid injection to the lower surface of the belt 20. To this end, the hydraulic pressure providing unit 30 includes a belt support 32, an injection nozzle 34, a water level control unit 36, a water supply line 40, and a drain line 45.

The belt support part 32 is formed in a wider width than the belt 20 and is installed below the belt 20. In this case, the belt support part 32 is disposed to be spaced apart from the belt 20 by a predetermined interval, and fluid flows between the belt 20 and the belt support part 32 to support the belt 20.

Thus, the belt support part 32 is formed corresponding to the shape of the belt 20. That is, the belt support part 32a which supports the conveyance part T whose cross section is formed in the curve is formed in the curve which a cross section makes parallel with the conveyance part T. Similarly, the belt support part 32b which supports the return part R in which a cross section is formed in a straight line is formed in the straight line whose cross section is parallel to the return part R. As shown in FIG.

In addition, the belt support part 32 is formed with drainage passages 33 on both sides thereof along the traveling direction of the belt 20. The drainage path 33 is for sending the fluid supplied on the belt support part 32 through the injection nozzle 34 to the drainage line 45 to be described later, and the two are parallel at positions corresponding to both sides of the belt 20. Is formed.

In the present embodiment, the drainage passage 33 is formed on the lower surface of the belt support portion 32 in the form of a tube, so that the fluid on the belt support portion 32 flows into the drainage passage 33 through the plurality of drainage holes 33a. It is composed. However, the present invention is not limited thereto, and may be configured in various forms as long as the fluid on the belt support 32 can be easily drained to the drain line 45 without leaking to the outside.

The spray nozzle 34 is inserted into the belt support 32 and fastened to the belt support 32. The injection nozzle 34 injects the fluid flowing from the outside upwards, that is, in the direction in which the belt 20 is disposed.

The belt 20 floats upward by the fluid injected from the injection nozzle 34. In addition, as the fluid is continuously injected from the injection nozzle 34, the belt 20 is continuously maintained in a floating state in the belt support (32).

Here, as shown in Figure 6, the injection nozzle 34 according to the present embodiment is fastened so that the injection direction toward the traveling direction of the belt 20. Therefore, the fluid injected from the injection nozzle 34 causes the belt 20 to rise and simultaneously pushes the belt 20 in a specific direction (that is, the advancing direction of the belt).

A plurality of such spray nozzles 34 may be disposed as necessary. That is, if the entire surface of the belt 20 may not be in contact with the belt support 32, a plurality of them may be appropriately arranged in various positions.

The level control unit 36 adjusts the level of the fluid flowing between the belt 20 and the belt support 32. To this end, the water level control unit 36 according to the present embodiment includes a float valve 37 and a transfer pipe 38.

As shown in FIG. 7, one end of the transfer pipe 38 is installed at the bottom of the belt support 32, and a float valve 37 is disposed inside the one end. The water level control unit 36 flows the fluid between the belt 20 and the belt support 32 to the drain line 45 as the float valve 37 moves.

The float valve 37 is buoyant in the fluid such that its upper surface is always in contact with the lower surface of the belt 20. Therefore, when too much fluid flows between the belt 20 and the belt support part 32, the belt 20 is excessively injured, and the float valve 37 is also injured together. Accordingly, the fluid between the belt 20 and the belt support 32 flows out through the transfer pipe 38 to the drainage line 45, thereby causing an appropriate amount of fluid between the belt 20 and the belt support 32. Only fluid remains and the belt 20 and float valve 37 are also in place.

On the other hand, in this embodiment, the other end of the transfer pipe 38 is disposed to face the belt support portion 32b disposed below the return portion (R). Accordingly, the fluid introduced into the transfer pipe 38 is discharged onto the belt support part 32b and is recovered to the drain line 45 through the drainage path 33 of the belt support part 32b. However, the present invention is not limited thereto, and various applications are possible, such that the other end of the transfer pipe 38 is directly connected to the drain pipe 46.

The feed line 40 supplies fluid to the spray nozzle 34. To this end, the water supply line 40 according to the present embodiment includes a pump 44, a water supply pipe 41, a pressure regulator 43, and a water quantity control valve 42.

The pump 44 continuously supplies the fluid to the spray nozzle 34. At this time, the fluid supplied from the pump 44 is supplied to each injection nozzle 34 through the water supply pipe 41.

The pressure regulator 43 is coupled to the water supply pipe 41, and is provided to adjust the pressure of the fluid supplied from the pump 44.

The water supply control valve 42 is installed in the water supply pipe 41 connected to each injection nozzle 34 of the water supply pipe 41. This water quantity control valve 42 is provided to adjust the amount of fluid supplied to each injection nozzle (34).

The drain line 45 includes a drain pipe 46, a sump 47, and a supply tank 48, and serves as a passage for recovering the fluid introduced into the belt support 32.

The drain pipe 46 is used as a passage through which the fluid supplied to the belt 20 is drained to the sump 47 which will be described later. One end of the drain pipe 46 is fastened to the drain channel 33 of the belt support 32 described above, and the other end thereof is connected to the sump 47. Accordingly, the fluid flowing into the drainage passage 33 of the belt support 32 is moved to the sump 47 through the drainage pipe 46.

Sump 47 is where the fluid moving through drain 46 is temporarily stored. While the fluid is stored in the sump 47, the impurities contained in the fluid settle to the bottom of the sump 47. Therefore, the sump 47 also performs the function of purifying the fluid.

The fluid purified by the sump 47 flows into the supply tank 48 and is stored. The water supply pipe 41 described above is connected to the supply tank 48. Therefore, the fluid stored in the supply tank 48 is supplied to the water supply pipe 41 by the drive of the pump 44 mentioned above.

On the other hand, the drain line 45 according to the present embodiment may be provided with a pipe (not shown) for replenishing the fluid. In this case, a pipe for replenishing the fluid may be connected to the supply tank 48 to supply the fluid directly to the supply tank 48. However, the present invention is not limited thereto.

The frame 11 is configured to support the hydraulic pressure providing unit 30. That is, the frame 11 is fixed from the ground so that the belt support 32 supporting the belt 20 and the water supply pipe 41 and the drain pipe 46 fastened to the belt support 32 can be firmly fastened to each other. I support them. By the frame 11, the belt 20 and the hydraulic pressure providing unit 30 may be stably driven when the conveyor 100 is driven.

Hereinafter, the operation of the belt conveyor 100 according to the present embodiment will be described with reference to FIGS. 2 to 7. The configuration of the belt conveyor 100 described above will also be clearer from the following description.

First, a shipment (not shown) is loaded onto the conveying portion T of the belt 20 via a charging chute (not shown).

Subsequently, the belt 20 performs the tracked motion by the belt driving means 5. In this way, the transported object supplied to the conveying unit T of the belt 20 is conveyed to a specific position according to the movement of the belt 20, after which the transported product, which has been transported, is dropped from the belt 20.

In this process, the belt conveyor 100 according to the present embodiment floats the belt 20 through the hydraulic pressure providing unit 30 to transport the goods. This process is described in more detail as follows.

First, the pump 44 of the water supply line 40 is operated so that the fluid stored in the supply tank 48 moves along the water supply pipe 41. At this time, the fluid is maintained at an appropriate pressure by the pressure regulator 43, and only the necessary amount is supplied to the injection nozzle 34 by the water amount adjustment valve 37.

The fluid injected through the injection nozzle 34 is injected toward the lower surface of the belt 20. Accordingly, the belt 20 is lifted upward by the injection pressure, and the injured state is maintained due to the continuously supplied injection pressure.

In this process, the injection nozzle 34 injects fluid in the advancing direction of the belt 20. Therefore, the fluid injected from the injection nozzle 34 pushes the belt 20 in the advancing direction of the belt 20 to move the belt 20.

In addition, the upper surface of the conveying portion (T) of the belt on which the shipment is loaded is disposed from the return portion (R) to the lower surface. Accordingly, the belt 20 according to the present embodiment has a fluid sprayed on both sides by a plurality of injection nozzles 34, so that the effect of continuously cleaning the deposits or impurities remaining on the surface of the belt 20 can be obtained. have.

In addition, the hydraulic pressure providing unit 30 according to the present embodiment adjusts the fluid level on the belt support unit 32 at all times by using the water level adjusting unit 36. Accordingly, even if the pressure applied to the belt 20 varies depending on the weight of the transport object, the belt 20 can maintain a constant curved shape by automatically adjusting the water level.

On the other hand, the fluid injected into the belt 20 through the injection nozzle 34 is moved along the belt 20 and the belt support 32 to flow into the drain 33. In addition, the fluid introduced into the drainage passage 33 is stored in the sump 47 along the drain pipe 46, and precipitates a byproduct or impurities in the sump 47, and then moves back to the supply tank 48.

As the above process is repeatedly performed, the belt 20 continuously maintains the injured state and transfers the transported goods seated on the belt 20.

Since the belt conveyor according to the present invention configured as described above does not use the supporting roller as in the prior art, it is not necessary to replace the rollers, and the wear of the belt due to the friction between the roller and the belt can be prevented, thereby improving the life of the belt. Can be extended.

In addition, since the belt is continuously cleaned during the conveyance, by-products do not fall and accumulate in the lower portion of the belt conveyor, thereby preventing environmental pollution.

On the other hand, the belt conveyor according to the present invention described above is not limited to the above-described embodiments, various applications are possible. For example, in the above-described embodiment, the case of using water as a fluid is taken as an example. However, the present invention is not limited thereto, and various other liquids or gases may be selectively used as needed.

In addition, the belt may be formed of a material having a high buoyancy corresponding to the fluid so that the belt may float more easily.

In addition, the present embodiment has been described using the belt and the hydraulic pressure providing unit used in the belt conveyor as an example, but is not limited thereto, and may be widely applied to a device for transporting a cargo using a flat plate such as a belt or a belt.
