Description

Bearing chain and cargo discharging device with same Technical Field The invention relates to the technical field of transmission devices, in particular to a bearing chain and a cargo discharging device with the same. Background In small-sized automatic object delivery equipment such as vending machines and game machine prize exchanging devices, a conveying chain structure which can be flexibly adjusted according to the length of a delivery channel and is convenient for on-site assembly is needed. The traditional conveying chain usually adopts a riveting mode to fixedly connect the outer chain plate with the pin shaft, and if a user needs to intercept or lengthen the chain according to the actual installation length, the riveting position is damaged by a special tool or an expensive special joint is used for connection, so that the operation is complex and the workload is large. The Chinese patent application CN115539572A discloses a simply detachable chain, which adopts the basic framework of the traditional roller chain and comprises an outer chain plate, an inner chain plate, a sleeve and a pin shaft, and is characterized in that a clamping groove is arranged at the inner side of the end part of the pin shaft, the inner side of the end part of the outer chain plate is provided with a gourd-shaped chute, the fixing is realized by sliding the clamping groove into the small end of the chute during assembly, and the outer chain plate can be taken out by sliding the clamping groove towards the large end of the chute by clamping related parts during disassembly. Although the technical scheme solves the problem that the traditional chain is difficult to disassemble and assemble after riveting to a certain extent, the chain still adopts the classical structure of the roller chain, and the assembly of one chain link can be completed only by the cooperative matching of the four different types of components of the outer chain plate, the inner chain plate, the sleeve and the pin shaft, wherein the connecting function is dispersed on the two components of the pin shaft and the outer chain plate, the two components must be used in pairs and cannot be interchanged, so that the components of the chain are various and the universality of the parts is poor. In summary, the chain disclosed in the prior art still has the technical defects of poor universality of parts and incapability of realizing direct interconnection between links due to the adoption of the multi-component distributed connection architecture, and is difficult to meet the actual requirements of the small-sized object shipment device on the assembly flexibility and the modularization degree of the chain. Disclosure of Invention The invention mainly aims to provide a bearing chain and a shipment device with the same, and aims to solve the technical problems that parts in the prior art are poor in universality and direct interconnection between chain links cannot be realized. In order to achieve the above purpose, the invention provides a bearing chain, which is formed by connecting a plurality of chain links, wherein each chain link comprises a hooking part and a pivot part, every two adjacent chain links are detachably clamped and connected through the hooking part and the pivot part, and can swing relatively, and at least one chain link is provided with a loading part. Further, the hooking portion defines a hooking cavity with an opening at one side, and the size of the transition position between the opening and the hooking cavity is smaller than or equal to the radial size of the pivot portion. Further, the opening size of the hooking portion expands from inside to outside. Further, at least one side of the opening is outwardly expanded in the form of an arc surface, an inclined surface or a combination of the arc surface and the inclined surface. Further, the region of the link where the pivot portion is provided and the region of the link where the hooking portion is provided form a stepped arrangement in the axial direction of the pivot portion, and the region of the hooking portion protrudes from the region of the link where the pivot portion is provided in the axial direction of the pivot portion. Further, the hook portion is formed by the hook body that the arc bending of chain link one end extends, and the step face that the chain link set up the region of pivot portion and the region that the chain link set up the hook portion formed is the cambered surface that suits with hook portion preceding terminal surface, and after adjacent chain link detachable block connects, the region that the chain link set up the pivot portion and the region that the chain link set up the hook portion overlap at least partially, and the region parallel and level or roughly parallel and level that two adjacent chain links set up the hook portion. Further, the end of the step surface extends out of a limiting portion for limiting the swing amplitude of the hooking p
