Description

Technical Field

[0001] The utility model relates to the technical field of accessories for scraper conveyors, and particularly to a chain connection structure for a scraper conveyor with high efficiency and wear resistance. Background Technique

[0002] A scraper conveyor is an important equipment for transporting bulk materials, and is widely used in fields such as coal mines, chemical mines, metal mines and power plants. A scraper conveyor is a conveyor that uses a scraper chain to tow and transport bulk materials in a trough. It mainly consists of three parts: a head, a middle part and a tail part, and also includes accessory components such as a hydraulic jack device for pushing the conveyor and a chain tightener for chain tightening.

[0003] Since a scraper conveyor uses a scraper chain for traction, a common scraper chain includes a chain. When using the chain for conveying, since the chain needs to mesh with the sprocket, at this time, wear between the chain and the sprocket will inevitably occur. However, most scraper conveyors lack components that can lubricate the connection part between the chain and the sprocket, which will cause an increase in friction, is not conducive to achieving the effect of high efficiency and wear resistance, and affects its service life. In view of this, we propose a chain connection structure for a scraper conveyor with high efficiency and wear resistance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a chain connection structure for a scraper conveyor with high efficiency and wear resistance to solve the defects mentioned in the above background technique.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a chain connection structure of a high-efficiency and wear-resistant scraper conveyor, including a sprocket 1, on which a chain 10 is engaged. The number of sprockets 1 is two, and the chain 10 is sleeved on the two sprockets 1. A driving motor 11 is coaxially arranged on one of the sprockets 1 to realize driving the chain 10 to rotate by the rotation of the sprocket 1;

[0026] Specifically, an oil lubrication assembly 2 is arranged below the chain 10. The oil lubrication assembly 2 includes an oil storage channel 20. A storage tank 201 is arranged inside the oil storage channel 20. The sprocket 1 and the chain 10 are located directly above the storage tank 201. A filter cartridge 23 and a micro oil pump 27 are arranged on one side of the oil storage channel 20. An outflow pipe 21 is fixedly installed at the end of the oil storage channel 20. The filter cartridge 23 is connected to the outflow pipe 21 through an outlet pipe 22. A filter screen 24 is arranged inside the filter cartridge 23. The micro oil pump 27 is connected to the filter cartridge 23 through a suction pipe 26. A three-way pipe 28 is fixedly installed at the oil outlet end of the micro oil pump 27. A three-way valve 281 is fixedly installed on the three-way pipe 28. Another pipe body of the three-way pipe 28 is fixedly installed with a spraying pipe 29. The end pipe body of the spraying pipe 29 is located directly above the sprocket 1, so as to realize lubricating the sprocket 1 by using the micro oil pump 27 to convey oil. After lubrication, the friction can be reduced, and the effect of high efficiency and wear resistance can be achieved.

[0027] In this embodiment, the remaining pipe body of the three-way pipe 28 is arranged vertically downward for discharging waste oil.

[0028] Specifically, a valve 211 is fixedly installed on the outflow pipe 21, and the inner diameter of the outflow pipe 21 is 1.3 cm to 1.8 cm, facilitating the opening of the valve 211 for the discharge operation of the oil fluid.

[0029] Furthermore, the end pipe body of the oil outlet pipe 22 is located above the filter screen 24, and the end pipe body of the suction pipe 26 is located below the filter screen 24, realizing the filtration operation of the oil fluid by using the filter screen 24.

[0030] In addition, a support ring 231 is fixedly installed on the inner wall of the filter cylinder 23, and a fixing ring 241 is fixedly installed on the filter screen 24. The fixing ring 241 is fixedly installed on the upper surface of the support ring 231 through a plurality of fastening screws, facilitating the fixing installation operation.

[0031] It is worth noting that a top cover 25 is hinged on the top surface of the filter cylinder 23, and a handle 251 is fixedly installed on the back surface of the top cover 25. Closing the top cover 25 can achieve the effect of dust-proof protection.

[0032] It should be noted that the height of each part of the oil outlet pipe 22 decreases successively from top to bottom, and the inner diameter of the suction pipe 26 is 0.5 cm to 0.8 cm, making it more smooth for the oil fluid to enter the filter cylinder 23 along the oil outlet pipe 22; the lower half of the chain body of the chain 10 is located above the plane of the top surface of the oil storage channel 20, and the sprocket 1 is located at the end of the storage tank 201, so that the existence of the oil storage channel 20 will not affect the normal operation of the chain 10 and the scraper conveyor.

[0033] When the high-efficiency and wear-resistant chain connection structure of the scraper conveyor of the present utility model is in use, the valve 211 is opened, and the oil fluid in the storage tank 201 can enter the filter cylinder 23 along the outflow pipe 21 and the oil outlet pipe 22. After the oil fluid is filtered by the filter screen 24, the micro oil pump 27 is connected to an external power supply and made to work. The micro oil pump 27 works to realize the delivery of the filtered oil fluid to drip from the end of the pouring pipe 29. The dripping liquid medicine will drip down onto the sprocket 1. Since the sprocket 1 meshes with the chain 10 during rotation, with the continuous dripping of the oil fluid, a comprehensive lubrication operation of the sprocket 1 and the chain 10 can be achieved. After lubrication, the friction can be reduced to achieve high efficiency and wear resistance.

[0034] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
