Technical Field

[0001] The utility model relates to a coal forming machine, in particular to a spherical coal forming machine, and belongs to the technical field of coal processing. Background Art

[0002] Coal resources are abundant and are widely used in production and life. The larger the contact area with air during briquette combustion, the more oxygen will come into contact with the coal to aid combustion. Therefore, we need a better shape with a larger contact area and better production efficiency. Now the main mainstream shapes on the market are spherical and ellipsoidal, because the spherical area can have a larger contact area and is more convenient to manufacture.

[0003] A utility model disclosed in a Chinese patent document with the announcement number CN217671306U relates to the technical field of industrial coal processing, in particular to a spherical coal molding machine, which includes a shell, an active extrusion roller and a driven extrusion roller, a storage hopper is fixedly installed on the upper part of the shell, a driving shaft and a driven shaft are respectively installed in parallel in the middle cavity of the shell, an active extrusion roller is fixedly installed on the driving shaft, a driving gear and a driving gear are respectively fixedly installed on one end of the driving shaft, a driven extrusion roller is fixedly installed on the driven shaft, a driven gear is fixedly installed on one end of the driven shaft, the driving gear and the driven gear are meshed together, and arc-shaped concave dimples are evenly distributed on the outer sides of the active extrusion roller and the driven extrusion roller. The utility model has a reasonable and compact structure and is easy to use. Through the coordinated use of the active extrusion roller, the driven extrusion roller and the storage hopper, the purpose of pressing loose coal or pulverized coal into coal balls is achieved, and it has the characteristics of safety and reliability, is convenient for operation, improves combustion efficiency, and greatly reduces environmental pollution and waste of coal resources.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, the coal is broken up by the breaking rod during the falling process and then falls between the active extrusion roller and the driven extrusion roller, and is squeezed into spherical coal, which is convenient for operation. However, the shapes and sizes of coal are different, and the degree of dryness and wetness is different. If it is only broken up and then used to be squeezed into balls, it will affect the overall stability of the spherical coal after forming, which is not convenient for subsequent transportation and use.

[0005] Therefore, it is urgent to improve the spherical coal forming machine to solve the above-mentioned problems. Utility Model Content

[0030] Further, such as Figure 4 as well as Figure 1As shown, a first rotating shaft 13 and a second rotating shaft 14 are rotatably connected inside the square box 2, one end of the first rotating shaft 13 is connected to a first gear 15, a second motor 17 is provided outside the square box 2, an output end of the second motor 17 is connected to an end of the first rotating shaft 13 extending to the outside of the square box 2, a second gear 16 meshing with the first gear 15 is provided at one end of the second rotating shaft 14, the first gear 15 and the second gear 16 are both located inside the square box 2, a first extrusion roll 18 and a second extrusion roll 19 are fixedly connected to the first rotating shaft 13 and the second rotating shaft 14, respectively, the surface of the first extrusion roll 18 is in contact with the surface of the second extrusion roll 19, and under the action of the second motor 17, the first gear 15 and The second gear 16 drives the first rotating shaft 7 and the second rotating shaft 7 to rotate relative to each other, thereby driving the first extrusion roller 18 and the second extrusion roller 19 to rotate relative to each other.

The plurality of scraper rods 22 can effectively clean the coal accumulated at the plurality of feed ports 12.

[0032] like Figure 1-Figure 7As shown, the principle of the spherical coal forming machine provided in this embodiment is as follows: when in use, the first motor 4 drives the rotating rod 3 to rotate, and then drives the multiple baffles 21 fixed on the rotating rod 3 to make circular motion, and the coal enters the cylindrical box body 1 through the multiple feed ports 12 in the feed trough 23, and falls onto the umbrella-shaped circular screen 5. The lower end surfaces of the multiple baffles 21 are in contact with the upper end surface of the circular screen 5. The moving baffles 21 will push the coal located above the circular screen 5, and the coal particles that meet the size specifications will fall through the circular screen 5. Otherwise, they will fall to the outside of the cylindrical box body 1 through the discharge pipe 25. The coal screened by the circular screen 5 falls to the bottom of the cylindrical box body 1. At this time, the annular sprinkler pipe 601 will introduce the water from the water tank 603 into the water pipe 602 through the U-shaped water pipe 602. The water flow is evenly sprinkled on the coal. The coal absorbs water and has a certain viscosity. The rotating rod 3 drives the multiple rotating shafts 7 to rotate, and then drives the rotating tube 8 which is rotatably connected to the multiple rotating shafts 7. The third gear 10 at one end of the rotating tube 8 away from the rotating rod 3 makes a circular motion while the rotating shaft 7 makes a circular motion. The third gear 10 rolls forward on the annular toothed track 11 meshing with it, and then drives the rotating tube 8 and the multiple rake tooth plates 9 on the rotating tube 8 to roll forward. The moving rake tooth plates 9 will stir the coal that has absorbed water at the bottom of the cylindrical box 1, and push part of the coal through the guide trough 20 to fall to the position between the first extrusion roller 18 and the second extrusion roller 19 during stirring. Finally, the coal after extrusion forming is sent out of the square box 2 through the discharge trough 24.
