Abstract

(57) [Abstract] [Purpose] A screw 3 is disposed in a U-shaped trough 2 to prevent a trouble in which a conveyed product is stagnated at a portion of an intermediate bearing 5 of a screw conveyor 1 for transporting powder. [Structure] A semi-cylindrical guide plate 10 for guiding a transported object in the transport direction is provided close to the outer diameter of the screw blade 3 on a portion of the intermediate bearing 5 of the screw conveyor 1 and on the screw blade 3 before and after the intermediate bearing 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an intermediate bearing portion of a screw conveyor in which a screw is arranged in a substantially horizontal U-shaped trough.

[0002]

[Prior Art]

 In a screw conveyor that transports powder particles by arranging a screw in a substantially horizontal U-shaped trough and rotating this screw, if the length becomes long, the screw shaft must be supported midway. The bearing is suspended inside the trough and an intermediate bearing is provided.

FIG. 5 shows an intermediate bearing portion of a conventional screw conveyor 1, in which a U-shaped trough 2 is partially cut away to show a screw blade 3, a screw shaft 4, and an intermediate bearing 5. Since the blade of the screw 3 is omitted in such an intermediate bearing portion, as shown in FIG. 6, the transported object 6 is stagnant, and it does not pass through the bearing portion but protrudes above or to the side of the bearing. The stagnation of the transported material further hinders the transportation of the transported material 6, and in an extreme case, the transported material 6 circulates in the intermediate bearing portion, the rotational resistance of the screw becomes large, and the overload of the driving portion is interrupted.

[0004]

[Problems to be solved by the device]

 An object of the present invention is to provide a structure that prevents troubles occurring in the intermediate bearing portion of such a screw conveyor.

[0005]

[Means for Solving the Problems]

 The present invention has a semi-cylindrical guide plate for guiding a transported object in the transport direction on an intermediate bearing portion of a screw conveyor for transporting powder by arranging a screw in a U-shaped trough and the screw blades in front of and behind it. This is the structure of the intermediate bearing part of the screw conveyor, which is characterized by being provided close to the outer diameter. It is preferable to attach this semi-cylindrical guide plate to the casing of the intermediate bearing, and the inspection of the bearing is not hindered by providing the inspection hole of the bearing on the side surface of the U-shaped trough.

[0006]

[Action]

 Since the intermediate bearing of the screw conveyor does not have screw blades, the cargo is stagnant here and sticks out to the side or above the intermediate bearing. According to the present invention, the semi-cylindrical guide plate that guides the transported object in the transport direction is provided so as to cover the intermediate bearing and the screw vanes in front of and behind it. Since the thrust force of the screw blade is transmitted to the package without the screw blade via the guide tube, the package advances in the transport direction while filling the guide tube.

【Example】

 1 is a partially cutaway perspective view of an intermediate bearing portion of a screw conveyor 1 according to an embodiment of the present invention. A semi-cylindrical guide plate 10 was provided to cover the intermediate bearing 5 and the screw blades 3 before and after the intermediate bearing 5. FIG. 2 is an exploded view showing the disassembly and assembly. The intermediate bearing 5 is composed of the upper metal 5a, 5b, the binding bolt 5c, its nut 5g, the casing 5d, the lid 5f and the mounting bolt 5h, so that the guide plate 10 of the present invention is integrated with the casing 5d. When installed, the guide plate 10 is easily installed, and the intermediate bearing is easily installed and disassembled. FIG. 3 shows a state in which the inspection window 7 of the intermediate bearing portion is attached to the side portion of the U-shaped trough 2, and the installation of the guide plate 10 of the present invention makes it difficult to inspect the bearing. This is preferable in order to solve the problem. FIG. 4 is an explanatory view showing a state in which the article 6 is guided around the intermediate bearing 5 by the guide plate 10 of the present invention and is fed by the screw conveyor.

[0008]

[Effect of the device]

 According to the present invention, it is possible to prevent the stagnation of the conveyed object in the intermediate bearing portion of the screw conveyor.
