Description

[Detailed description of the invention] The present invention relates to a chain for a pipe conveyor, and more specifically, the purpose of the invention is to provide a chain for a pipe conveyor that is excellent in transporting extremely fine objects such as powder, granules, and muddy substances. .

Depending on the nature of the material to be conveyed and its arrangement, the pipe conveyor chain is most suitable for flights of various shapes, such as offset circular flights a, facing half-moon flights b and b, as shown in Figures 1A and 2A. Use the selected one.

However, in the pipe conveyor chain in the prior art, flights a, b,
Due to the shape of b and the state of its attachment to chain link c, a gap d is inevitably created as shown in Figures 1B and 2B, which has the disadvantage that the transported items may leak, especially when transporting small items. Was.

The pipe conveyor chain of the present invention was developed in consideration of the above points, and the entire shape is a flat plate approximately in the shape of a half-moon.
A required chain piece for configuring a chain for a pipe conveyor, in which two divided flights each having a chain link tight-fitting recess formed approximately in the center of the straight side thereof are brought into contact with each other at the straight side thereof. A pipe that is closely fitted vertically facing the chain link of the chain link, and that the split flight is detachably attached to an attachment formed integrally with the chain link, thereby eliminating gaps and preventing cargo from leaking. The purpose is to provide a conveyor chain.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 and 7. In the figure, 1 is a half-moon-shaped flat plate, and two chain pieces 4 (to be described later) are attached to two locations approximately at the center of the straight side 3. The chain for a pipe conveyor of the present invention is a divided flight formed with chain link tight-fitting recesses 2, 2 for tightly fitting the chain links 5, 5, and the chain for a pipe conveyor of the present invention has a divided flight 1 having such a shape.
Attach and use the required number of sets of two. Therefore, in order to install the required chain pieces 4 constituting the chain for a pipe conveyor, the chain pieces 4 are placed vertically facing each other on the chain links 5, 5 so that the divided flights 1, 1 are in contact with each other at their straight sides 3, 3. The abutting straight side portions 3, 3 between the divided flights 1, 1 are tightly fitted.
In addition, the tightly fitted portion between the divided flights 1, 1 and the chain links 5, 5 is completely closed, so that there is no risk of leakage of the transported goods. In addition, in order to fix the above-mentioned divided flights 1, 1 to the chain links 5, 5,
The divided flights 1, 1 are integrally formed with the chain links 5, 5, and the chain links 5, 5
Bolts 7, 7... and nuts 8, 8... are held between four pieces of attachments 6, 6, which form the same plane perpendicular to the traveling direction of the pipe conveyor chain at both ends in the longitudinal direction. Therefore, the attachments 6, 6, . . . and the divided flights 1, 1 are provided with bolt through holes 9, 9, . . ., 10, 10, .

As explained above, the pipe conveyor chain of the present invention has a configuration in which the split flights, which are installed in pairs, are brought into contact with their straight sides, and the split flights and the chain links are tightly fitted. It is possible to transport objects, especially small objects such as powder, without leaking them. In addition, in the pipe conveyor chain of this invention, the above-mentioned divided flights are attached to the chain links with bolts and nuts, so they can be attached and detached freely, and not only is it easy to disassemble and clean, but it is also easy to change the items to be transported. It can be replaced with a flight that takes the appropriate shape,
The practical effects of the present invention are extremely large, as it not only reduces the manufacturing cost but also facilitates inventory management.
