For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] The utility model provides a structure of a slag discharge roller which is convenient for collecting coal slag. Figures 3 to 7 As shown, it includes a rotating shaft 4, the surface of which is connected to a cylinder assembly 1, and the cylinder assembly 1 can discharge coal slag from both ends; the cylinder assembly 1 includes a flat steel 11, a cone 12, a wheel rim 13, a rib plate 14 and a wheel hub 15, and two groups of wheel hubs 15 are provided. The two groups of wheel hubs 15 are respectively fixedly connected to the left and right ends of the rotating shaft 4, and the surface of the cylinder assembly 1 between adjacent wheel hubs 15 is fixed with a wheel rim 13, and the outer wall of the wheel rim 13 is installed with a flat steel 11, and both ends of the flat steel 11 are connected to the wheel hub 15. The surface of the flat steel 11 is fixedly connected, and the surface of the flat steel 11 is provided with slag discharge grooves 111 with equal intervals. Cones 12 are installed on the left and right sides of the rim 13. The diameter of the cone 12 decreases successively from the rim 13 to the hub 15, and the end of the cone 12 is fixedly connected to the surface of the hub 15. Ribs 14 with equal intervals are welded on the outer wall of the cone 12, and the number of the ribs 14 is equal to the number of spokes of the hub 15, and the two ends of the ribs 14 are welded to the spokes of the two hubs 15.

[0025] During implementation, the coal slag will fall on the surface of the flat steel 11, and then fall into the surface of the cone 12 through the slag discharge groove 111 during rotation. After falling, the rib plate 14 will block the spokes of the hub 15 to form a slag discharge channel to prevent the coal slag from leaking out from both sides. At the same time, since the cone 12 is a conical structure, the coal slag that falls on the surface of the cone 12 will be discharged from the gaps between adjacent spokes of the hub 15 at both ends.

[0026] Furthermore, if Figure 1 as well as Figure 2 As shown, the two ends of the rotating shaft 4 and the outer side of the cylinder assembly 1 are both installed with a bearing seat assembly 2, and the outer wall of the bearing seat assembly 2 is provided with a collecting assembly 3, which is used to collect the coal slag discharged from the two ends. The bearing seat assembly 2 includes a spherical roller bearing 21 and a housing seat 22. The inner ring of the spherical roller bearing 21 is fixedly connected to the end of the rotating shaft 4, and the outer ring of the spherical roller bearing 21 is fixedly connected to the housing seat 22, and the housing seat 22 is fixed at the place to be installed. The collecting assembly 3 includes a support frame 31, a collecting box 32 and a dovetail slider 33. The support frame 31 is provided with two groups, and the two groups of support frames 31 are fixedly connected to the outer wall of the bottom of the two housing seats 22 by screws. The bottom of the housing seat 22 is placed with a collecting box 32, which is used to collect the discharged coal slag, and the collecting box 32 and the support frame 31 are slidably matched with each other through the dovetail slider 33.

[0027] During implementation, the support frame 31 is fixedly connected to the surface of the outer shell seat 22 by screws, and then the collection box 32 is slid into the surface of the support frame 31 through the dovetail slider 33, and the coal slag discharged from the end is collected by the collection box 32, and after collection, it is poured into the belt for transportation.

[0028] Furthermore, if Figure 2 as well as Figure 8 As shown, the surface of the collecting component 3 is also connected to a slag cleaning mechanism 5, which is used to clean the slag from the surface of the flat steel 11. The slag cleaning mechanism 5 includes a hollow material receiving frame 51, a slag cleaning scraper 52 and an adjusting bolt 53. The hollow material receiving frame 51 is detachably connected between adjacent support frames 31, and the hollow material receiving frame 51 can receive the coal slag scraped off by the slag cleaning scraper 52 and discharge it from both ends to the collecting box 32; the surface of the hollow material receiving frame 51 is threadedly connected with an adjustable slag cleaning scraper 52 through the adjusting bolt 53, and the slag cleaning scraper 52 is in contact with the surface of the flat steel 11, and the slag cleaning scraper 52 is used for scraping away coal slag.

[0029] During implementation, the adjusting bolt 53 is rotated to loosen it and the slag scraper 52, and then the slag scraper 52 is pulled to fit the flat steel 11. When the flat steel 11 rotates, the coal slag attached to the surface is scraped off by the slag scraper 52 and falls into the hollow receiving frame 51, and then discharged into the collection box 32 from both ends of the hollow receiving frame 51, thereby completing the cleaning of the attached coal slag.

[0030] Furthermore, if Figure 2 As shown, a flow guide mechanism 6 is connected to the surface of the rotating shaft 4 between the cylinder assembly 1 and the bearing seat assembly 2, and the flow guide mechanism 6 facilitates the flow diversion of the coal slag; the flow guide mechanism 6 is composed of a flow guide sleeve 61 and a sealing ring 62, the flow guide sleeve 61 is fixedly connected to the two ends of the rotating shaft 4, and one side of the flow guide sleeve 61 is in contact with the surface of the flat steel 11, and the flow guide sleeve 61 is used to guide the discharged coal slag to the collection box 32, and a sealing ring 62 is installed on the side of the flow guide sleeve 61 away from the flat steel 11, and the sealing ring 62 is rotated and tightly fitted with the outer shell seat 22, and the sealing ring 62 is used for sealing.

[0031] During implementation, the coal slag will directly fall into the groove on the surface of the guide sleeve 61 when discharged from both ends of the slag discharge roller, and the guide sleeve 61 will automatically discharge the coal slag into the collection box 32 when rotating. In the process, the sealing is achieved by the closed ring 62 to prevent it from entering the interior of the bearing seat assembly 2, which solves the problem that the existing slag discharge roller will fall onto the rotating shaft 4 when discharging slag, and avoids the splashing of coal slag when the rotating shaft 4 rotates.

[0032] Working principle: When in use, first fix the slag discharge roller at the desired position through the outer shell seat 22, and then install the collecting component 3 on the outer shell seat 22. During the subsequent belt transportation, some coal slag will fall on the surface of the flat steel 11, and then fall into the surface of the cone 12 through the slag discharge groove 111 during rotation. After falling, the spokes of the hub 15 are blocked by the rib plate 14 to form a slag discharge channel to prevent the coal slag from leaking from both sides. At the same time, since the cone 12 is a conical structure, the coal slag that falls on the surface of the cone 12 will be discharged from the gap between the adjacent spokes of the hub 15 at both ends, which solves the friction problem between the belt and the roller caused by the presence of coal slag on the surface of the existing slag discharge roller, thereby extending the service life.

[0033] Subsequently, the coal slag is collected by the collecting component 3. When the collecting component 3 is implemented, the support frame 31 is fixedly connected to the surface of the outer shell seat 22 by screws, and then the collecting box 32 is slid into the surface of the support frame 31 through the dovetail slider 33. The coal slag discharged from the end is collected by the collecting box 32, and after collection, it is poured into the belt for transportation, thereby realizing the collection and transportation of the fallen coal slag by the slag discharge roller, avoiding the waste of coal slag.

[0034] At the same time, during slag discharge, the coal slag will fall directly into the groove on the surface of the guide sleeve 61 when discharged from both ends of the slag discharge roller, and the guide sleeve 61 will automatically discharge the coal slag into the collection box 32 when rotating. During the process, the sealing ring 62 is used to prevent the slag from entering the interior of the bearing seat assembly 2, thereby solving the problem that the existing slag discharge roller will fall onto the rotating shaft 4 during slag discharge, and avoiding the splashing of coal slag when the rotating shaft 4 rotates.

[0035] When the slag discharge roller is in use, the coal slag attached to the surface of the slag discharge roller is removed by the slag cleaning mechanism 5. When the slag cleaning mechanism 5 is implemented, the adjusting bolt 53 is rotated to loosen it and the slag cleaning scraper 52, and then the slag cleaning scraper 52 is pulled to fit the flat steel 11. When the flat steel 11 rotates, the coal slag attached to the surface is scraped off by the slag cleaning scraper 52 and falls into the hollow receiving frame 51, and then discharged into the collecting box 32 from both ends of the hollow receiving frame 51, thereby completing the cleaning of the attached coal slag and finally completing the use of the slag discharge roller.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
