Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a device for attaching various attachments such as scrapers, blades, and slats for conveying objects to a conveyor chain.

Prior Art The various attachments mentioned above are attached to the conveyor chain by welding to the link plates of the chain, or by fixing them with bolts, pins, rivets, etc.
Conventionally, attachment mounting devices such as those formed integrally with the link plate or the like have been commonly used.

With such conventional mounting devices, the entire conveyor chain must be replaced every time the type of attachment changes, or if the attachment is removably mounted with bolts, the screwing and unscrewing operations of bolts and nuts are difficult. It was inevitable that this would be extremely troublesome and require a great deal of effort and time.

Problems to be Solved by the Invention This invention attempts to extremely easily attach and remove only the attachment by using the same chain when changing the attachment to a different type of attachment without replacing the entire chain. It is.

Means for Solving the Problems The present invention is characterized in that a pair of elastic brackets along the outer side of the outer link plate of a conveyor chain is fixed to an attachment at one end of each, and a semicircular notch is formed in the edge of the one end of the bracket. A connecting pin insertion hole is formed at the other end of the bracket, and the outer end of the next connecting pin is inserted through the recess to fit the link plate connecting pin, and the bracket is inserted outside the chain. Removably attached to the outside of the link plate,
The idea is to use the elasticity of the bracket to replace attachments.

Function: When attaching an attachment to a conveyor chain, the connecting pin is fitted into the semicircular cutout recesses of a pair of brackets integrated into the attachment, and then the connecting pin insertion hole of the bracket is drilled. The other end of the bracket is expanded outwardly using the elasticity of the bracket, and the outer end of the connecting pin is inserted into the insertion hole to attach the bracket to the link plate.

Further, when the bracket is removed, it is done by reversing the order in which it was installed.

Embodiment FIG. 1 is a front view of a scraper 1 of a scraper conveyor attached to a chain 2. A pair of brackets 4, 4 attached to the scraper 1 along an outer link plate 3 of the chain are attached to the surface of the scraper 1. It is set at a right angle.

Semicircular notch recesses 6, 6 that fit into the connecting pins 5 of the chain are formed at one end edge of the brackets 4, 4 where the scraper 1 is provided, and the other end of the brackets 4, 4, that is, the free end Insertion holes 7, 7 are bored in the portion for inserting the next connecting pin.

Therefore, first, the bracket is stood upright, the semicircular notch recesses 6, 6 are fitted from above the connecting pins 5, 5, and rotated downward, and the scraper 1 is attached to the chain 2 as shown in FIGS. 1 and 2. At the same time, the distance between the free ends of the pair of brackets 4, 4 is expanded to a length greater than the length of the connecting pin by utilizing the elasticity of the brackets, and the connecting pin is inserted into the insertion holes 7, 7.
When inserted, both ends of the brackets are fitted to the front and rear connecting pins, and the brackets 4, 4 are attached closely along the outside of the outer link plates 3, 3 of the chain.

In addition, when removing the brackets 4, 4 from the outer link plates 3, 3, the free ends of the brackets are expanded to remove the connecting pins from the insertion holes, and when the brackets are rotated upward and lifted, the half is removed. Since the circular notch recesses 6, 6 are easily separated from the connecting pin, the attachment 1 can be easily removed from the chain 2.

Effects As described above, the present invention provides a chain link by providing a semicircular notch in the edge of one end of a pair of elastic brackets where an attachment is attached, and an insertion hole in the free end of the other end where an attachment is not attached. Because it can be attached to and detached from the connecting pin of the plate,
Even if one end edge of each of the pair of elastic brackets fixed to the attachment cannot be expanded, the semicircular notch can be easily fitted into the connecting pin, making it easy to install and remove the brackets from the chain. It is very simple and therefore very easy to replace the attachments that are integrated with the brackets and attach them to the chain, so by using one chain and replacing the attachments, the function of the conveyor chain can be changed to the conveyor chain. Since it can be selected depending on the type of object, its practical effects are great.
