Description

Technical Field

[0001] The utility model belongs to the technical field of reclaimer chains, and in particular relates to a reclaimer chain structure. Background Art

[0002] A reclaimer is a material-reclaiming device used to take out materials. Driven by a column structure, the reclaimer moves around the column structure, driving the material rake to rake the accumulated loose materials to the ground through the rake teeth. Through a series of movements of the scraper mechanism, the scraper scrapes the materials away from the center to the center of the stacker-reclaimer, and falls into the transfer chute, and then the belt conveyor under the stacker-reclaimer transports the materials away. Most reclaimers need to frequently use chain structures for the reciprocating motion of the reclaiming structure.

[0003] The chain structure of the reclaimer currently on the market has the following problems when in use:

[0004] 1. In the actual use of the traditional reclaimer chain structure, since the pin is sleeved inside the casing, when the chain structure is running, the gear teeth will come into contact with the surface of the casing when rotating. The casing of the traditional reclaimer chain structure has no protective structure on the outside. After long-term use, the surface of the casing is easily worn, and it does not have a good anti-wear effect;

[0005] 2. When most reclaimer chain structures are in use, because the joints between the ends of the pins and the panels are mostly directly exposed to the outside, some dust may get stuck in the gaps when the chain structures are running, causing the chain structures to run unsmoothly and affecting the normal operation of the chain structures, making it difficult to achieve the purpose of dust prevention. Utility Model Content

[0006] The utility model aims to provide a reclaimer chain structure to solve the technical problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a material reclaimer chain structure, including a back plate, the surface of the back plate is fixedly connected to a pin, a connecting plate is provided on the outside of the pin, the number of the connecting plates is two, a sleeve is provided between the connecting plates, the sleeve is sleeved on the outside of the pin, a protective sleeve is provided on the outside of the sleeve, the protective sleeves are connected by a rotating shaft, the surface of the protective sleeve is fixedly connected to a mounting plate, and bolts are provided inside the mounting plate.

[0008] Preferably, a panel is provided on the outside of the pin, the end of the pin passes through the panel, the panel is close to the connecting plate, and a cover plate is provided on the outside of the panel, and the cover plate is sleeved on the end of the pin.

[0009] Preferably, the surface of the panel is fixedly connected to an external threaded ring, the surface of the cover plate is fixedly connected to an internal threaded ring, and the outside of the internal threaded ring is connected to the external threaded ring by means of a threaded connection.

[0010] Preferably, the surface of the cover plate is fixedly connected to the turntable, the end of the pin is embedded and connected to the inside of the turntable, and a sealing ring is bonded to the surface of the turntable, and the sealing ring is sleeved on the outside of the pin.

[0011] Preferably, an annular groove is provided inside the protective sleeve, a gasket is provided inside the annular groove, and the inner wall of the gasket is in close contact with the sleeve.

[0012] Preferably, a positioning block is fixedly connected to the inner wall of the protective sleeve, a positioning groove is provided on the surface of the sleeve, and the positioning block is embedded and connected inside the positioning groove.

[0013] The utility model has the following advantages:

[0014] 1. A reclaimer chain structure is provided with a protective cover on the outside of the casing, the surface of the protective cover is fixedly connected to the mounting plate, the mounting plate is provided with bolts inside, and the protective cover covers the outside of the casing. In this way, when the chain structure is running, the gear teeth of the gear will contact the protective cover instead of directly contacting the surface of the casing, thereby preventing the outer part of the casing from being worn due to long-term contact, and making it have an anti-wear effect;

[0015] 2. This kind of reclaimer chain structure has a cover plate on the outside of the panel, and the pin passes through the connecting panel.
