Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically a chain structure for a cement scraper conveyor. Background Technology

[0002] Scraper conveyors are a common type of cement conveying equipment. They use chain-driven scrapers to transport cement within a closed casing, effectively reducing dust generated during cement transport. Currently, in most commonly used scraper conveyors, the scrapers are fixed to the chain plates or connecting plates on the chain plates by several bolts, which is relatively cumbersome to operate and inconvenient to replace when the scrapers are damaged or severely worn.

[0003] A search revealed that patent CN217295979U discloses a heavy-duty buried scraper conveyor chain. The chain plate and buried scraper are detachable, allowing for quick replacement of the chain plate and buried scraper and reducing replacement costs. It is equipped with a receiving groove and an inclined surface to further enable quick assembly and disassembly of the buried scraper and the chain plate. It is also equipped with a limiting block to prevent the end of the positioning block from sliding out of the inner cavity of the T-shaped insert and causing the positioning spring to be overstretched, thereby damaging the positioning spring.

[0004] While the above solution enables quick assembly and disassembly between the chain plate and the scraper, the scraper is only connected to the T-slot on the chain plate via a T-shaped insert at the end. The connection between the scraper and the T-shaped insert is relatively weak, making it prone to breakage when the scraper is under stress. Furthermore, it is difficult to guarantee the structural strength of the area where the T-slot is opened on the chain plate, resulting in poor reliability of the chain and requiring improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a chain structure for a cement scraper machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chain structure for a cement scraper conveyor includes several chain plates, pins, and scrapers. Each chain plate has a first connecting end and a second connecting end integrally formed at both ends, and both the first and second connecting ends are fitted onto corresponding pins through through holes. One end of each pin is fitted with a cotter pin. A connecting plate is fixedly connected to the middle of the outer wall of each chain plate, and an opening groove is formed at the top of each connecting plate. One end of each scraper is fixedly connected to a sleeve adapted to the connecting plate. A set screw is threaded through a threaded hole at the top of the sleeve, and the set screw is adapted to the opening groove. Baffles are fixedly connected to both outer walls of the sleeve, and the baffles are in contact with the outer walls of the chain plates.

[0008] As a further embodiment of this utility model: the inner wall of the opening groove on the side away from the chain plate is an inclined surface, and the bottom end of the top screw is provided with a conical surface, and the bottom conical surface of the top screw is in contact with the inclined surface.

[0009] As a further embodiment of this utility model: the outer wall of the baffle is welded and fixed with reinforcing ribs, and the reinforcing ribs are welded and fixed with the corresponding sleeves.

[0010] As a further embodiment of this utility model: rollers are rotatably mounted on the pin shaft.

[0011] As a further improvement of this utility model: each of the pins is symmetrically fitted with two first connecting ends and two second connecting ends, and the two first connecting ends and the two second connecting ends are symmetrically distributed on both sides of the roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when a scraper needs to be installed on the connecting plate, simply put the sleeve at the end of the scraper onto the connecting plate, and then rotate the set screw in the threaded hole so that the set screw is inserted into the open slot. The scraper can then be fixedly installed on the chain plate. The operation is simple and convenient. Furthermore, with the setting of two baffles, when the scraper is conveying cement, the force on the scraper will be transmitted to the chain plate through the baffles, thereby extending the service life of this chain structure.

[0019] Please see Figures 1-3 In this embodiment of the utility model, a chain structure for a cement scraper machine includes several chain plates 1, pins 5, and scrapers 11. The two ends of the chain plates 1 are integrally formed with a first connecting end 2 and a second connecting end 3, and the first connecting end 2 and the second connecting end 3 are both sleeved on the corresponding pins 5 through through holes 4. One end of the pins 5 is provided with a cotter pin 6. A connecting plate 8 is fixedly connected to the middle of the outer wall of each chain plate 1. The top of the connecting plate 8 is provided with an opening groove 9. One end of the scraper 11 is fixedly connected with a sleeve 12 that is adapted to the connecting plate 8.
