2. Description of the Related Art Screw conveyors are widely used for transporting powdered and granular materials such as cement, fine powder, grains, gravel, wood chips, and coal, and semi-fluid materials such as asphalt and coal tar. The spiral groove surrounded by is not only filled with the package during transportation, but also may be filled with the package during stop even depending on the installation location and application.

FIG. 7 shows an example of starting a screw conveyor in a stopped state when the screw conveyor is buried in the package and therefore the groove is filled with the package.

That is, in FIG. 7, the screw conveyor 63 is arranged in a cantilever manner with its base end positioned at the center of the bottom wall 62 of the storage 61 of the granular material which is a bulk material, and this screw conveyor 63 is rotated. While swinging along the bottom wall 62, the granular material stored in the storage 61 is sequentially moved from the bottom portion to the central portion of the bottom wall 62, and the belt conveyor arranged below the bottom wall 62 from the outlet 64. It is made to drop to 65 and carried out from the storage 61.

In this discharging facility, the screw conveyor 63 is used as a screw feeder for feeding the powdery material in the storage 61 to the belt conveyor 65 for carrying out, and is buried in the powdery material from the start of the storage of the powdery material to the end of the discharging. ing.

Therefore, the screw conveyor 6 is used for paying out.
Driving 3 requires a much higher starting torque than starting with an empty groove. Even if the storage is a fixed structure such as a silo, when it is stored for a long period of time, the granular material will naturally consolidate due to its own weight, and the structure will be subject to vibration and sway during navigation, such as the cargo hold of a cargo ship. In this case, the compaction is performed in a short time, and a larger starting torque is required.

On the other hand, the screw conveyor during transportation can be operated with a power that is a few times lower than the power required for startup, but the condition of the transported material, that is, the water and dirt on the surface of the granular material, the semi-fluid Depending on the viscosity of the elastic material, the frictional resistance against these blades is extremely large, and thus a considerably high power may be required.

In addition to this, when the screw conveyor 63 swivels the bottom portion of the layer of the granular material as shown in FIG. 7, it swivels while destroying the layer, so a large swiveling power against the resistance received from the side surface. Will be required.

For this reason, not only a high output rotary drive mechanism is used in order to withstand a high load during transportation that is applied due to a large starting torque and the state of a package, but also when it is used as a screw feeder for dispensing, a side surface is used. In order to overcome the resistance of the screw conveyor, a high-power swing drive mechanism must be used, and in order to withstand these loads and resistances, the screw conveyor and its supporting portion at the base end must be extremely strong.

In order to do so, not only a high output rotary drive mechanism and a swivel drive mechanism are required, but also the screw conveyor itself and its supporting portion need to have extremely high strength, which is extremely uneconomical.

When the groove is filled with a package to be started, first, the pressure fluid is ejected from the nozzle opening to form a lubricating surface at the contact portion between the front and rear surfaces of the blade and the package, or the package is transported. The fluidized state reduces the static frictional force and activates. Further, even when it is transported under a high load condition, the pressure fluid is jetted to reduce the kinetic frictional force. Further, when the screw conveyor swirls in the transported object, the jetted pressure fluid brings the transported object in the swirling front portion into a fluid state to reduce the pressure resistance from the side surface.

Embodiment 1 FIGS. 1 and 2 show an embodiment of the invention described in claim 1, which has an inlet 1 for an article to be transported at one end and an outlet for the other end. A screw conveyor 4 is installed in a pipe 3 having two and extending in the lateral direction,
Both ends of the shaft 5 are rotatably supported by both ends of the pipe 3 and are rotated by a prime mover (not shown).

When starting up in a state where the groove 8 is filled with the transported material, first the control valve 12 is opened and the accumulator 11 is opened.
When the pressurized air is introduced into the passage 7 and ejected from the nozzle port 9 to form a lubricated surface by an air film at the contact portion between the front and rear surfaces of the blade 6 and the transported object, or when the transported object is a granular material having a light specific gravity. Is blown up into a fluid state. As a result, the friction proportional to the vertical force exerted on the blades 6 by the transported object at the contact portion is reduced, so that the compressed air is activated while continuing to be ejected.

Since the front surface of the blade 6 is a portion that generates a static friction force at the time of starting and pushes and moves the transported object, resistance due to kinetic friction is always generated during transportation, whereas the rear surface of the blade 6 starts. Occasionally, a static friction force is generated, but since it is not directly involved in the movement of the transported object, almost no frictional resistance is generated during transportation. Further, since the kinetic frictional force is smaller than the static frictional force, it is possible to start the engine with a small starting torque in a state where the resistance due to the static friction is reduced by jetting the pressurized air. Further, after the start, even if the control valve 12 is operated to reduce the ejection amount or the ejection is stopped to carry the transported object, it can be driven with the same power as the conventional one.
If it is carried while continuing to eject at the same level as at startup, it can be driven with even lower power.
