The middle groove carries the function of carrying materials in the entire coal mining scraper conveyor. It is made by two methods: integral casting and casting welding. Although the middle groove can be formed, the actual effect of the product on the coal mining scraper conveyor is that there will be differences between the names, which can be found in the amount of wear.
Through the comparison of the use of one surface, it is found that the wear of the middle casting groove of the coal mining scraper conveyor is very good; the deformation and damage are basically not; the connection part of the rolling lug and the dumbbell pin has no obvious deformation and fracture; but the situation of the welding casting middle groove Different, there is severe wear and tear.
The results show that the middle groove of the coal mining scraper conveyor is cast as much as possible, so that the middle plate of the middle groove can be oriented along the running direction of the scraper; and the total number of wave patterns helps to reduce the scraper in the coal mining scraper conveyor. The contact area of the intermediate plate significantly reduces the friction resistance of the scraper and prolongs its service life.
However, when it is necessary to integrally cast the middle groove of the coal mining scraper conveyor, the entire material has as high strength and high wear resistance as possible, so the problem of welding and cracking of the middle plate and bottom plate completely overcomes the influence of the welding middle groove. It also avoids the situation that the groove of the other middle welding groove is easy to wear and the middle plate has relatively poor wear resistance.
Since the amount of wear is controlled, this means that the coal mining scraper conveyor basically does not need to be repaired during use, which greatly saves maintenance costs and improves production efficiency. The results show that, under the same conditions of use, the entire casting high strength, high wear and non-welded middle groove life is more than twice that of the welded middle groove, and the ratio of medium to medium is very obvious.
