With their efficient, continuous, and stable material conveying capabilities, they greatly improve production efficiency and automation levels. However, with the expansion of production scale and the increase in production intensity, the performance requirements for scraper conveyors are also increasing day by day.

A replenishing pipe 11 is fixedly communicated with the top of each water tank 10. Through the arrangement of the replenishing pipe 11, it is convenient for the user to replenish water and lubricating liquid. A stirring shaft 12 is rotatably connected between the front and rear inner side walls of each water tank 10. A group of stirring blades 13 are fixedly connected to the outer surface of each stirring shaft 12. Through the arrangement of the stirring blades 13, the purpose of stirring the lubricating liquid and water inside the water tank 10 can be achieved, achieving the dilution effect of the lubricant. Motors 14 are installed on the fronts of the two water tanks 10. The output end of each motor 14 is fixedly connected to the front end of the stirring shaft 12 close to it. Through the arrangement of the motors 14, power can be provided for the rotation of the stirring shaft 12.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3, at the top of each side plate 1, a set of brackets 15 are fixedly connected. At the top of each bracket 15, it is fixedly connected to the nozzle 7 closest to it. Through the setting of the brackets 15, the purpose of supporting the nozzle 7 can be achieved. On the sides of the two water tanks 10 away from each other, a pump body 16 is provided. The input end of each pump body 16 is fixedly connected to the water tank 10 closest to it. The output end of each pump body 16 is fixedly connected to a hose 17. The other end of each hose 17 is fixedly connected to the nozzle 7 closest to it.

[0036] In the middle trough of a wear-resistant scraper conveyor in this embodiment, through the rolling columns 6 provided on the bottom plate 4, when the chain returns, it can play a role in supporting the chain, effectively reducing the direct friction pressure between the chain and the bottom plate 4, greatly improving the overall wear resistance, and significantly extending the service life of the equipment. Continuous and stable lubrication supply: The lubrication system transports the lubricating fluid in the water tank 10 to the nozzle 7 through the pump body 16, and then sprays it onto the surface of the middle plate 2 at a downward inclined angle by the nozzle 8. This design ensures that the middle plate 2 can continuously obtain stable and appropriate lubricating fluid during operation, effectively avoiding dry friction and additional wear caused by insufficient lubrication, and at the same time, it can cool the high-temperature coal gangue or coal blocks.

[0037] The working principle of the above embodiment is as follows: First, when the scraper chain returns, the uniformly arranged rolling columns 6 on the bottom plate 4 can effectively support the chain, significantly reducing the direct contact and friction between the chain and the bottom plate 4, thereby enhancing the overall wear resistance and extending the service life of the equipment. Secondly, during the process of the scraper pushing the coal blocks to move, the control host 18 can regularly start the pump body 16. The pump body 16 extracts the lubricating fluid from the water tank 10 and transports it to the nozzle 7 through the hose 17. The multiple nozzles 8 on the nozzle 7 are set at a downward inclined angle to ensure that the lubricating fluid can be accurately sprayed onto the surface of the middle plate 2, forming a uniform lubricating film. As the scraper chain continues to operate, the lubricating film on the middle plate 2 is continuously replenished, effectively reducing the friction coefficient between the scraper and the middle plate 2, avoiding additional wear caused by dry friction. At the same time, the lubricating fluid can also cool the high-temperature coal gangue or coal blocks that may fall on the middle plate 2 during transportation to a certain extent, protecting the middle plate 2 from high-temperature damage.
