Description

Technical Field

[0001] The utility model relates to a discharge mechanism used for coal mine transportation, belonging to the technical field of coal mine transportation. Background Art

[0002] Coal transportation refers to the process of transporting mined coal from mines to factories, markets, or other destinations. It is an essential component of the coal industry, crucial not only to the development of the coal industry but also to the national economy. It is a critical link in the entire coal mining and utilization process, directly impacting coal production efficiency and utilization value. A sound transportation plan is the foundation of coal transportation management. By developing a detailed transportation plan, we can rationally arrange transportation time and capacity, improving transportation efficiency.

[0003] Coal mine transportation is an important process used in the transfer of coal production. Usually, material boxes are used to transport some coal over short distances. However, after the material box transports the coal to the designated location, some coal may easily remain during the unloading process, making it impossible to achieve fast and effective unloading. Although setting a slope at the bottom of the material box can achieve fast unloading, it will affect the loading capacity and bring inconvenience to subsequent operations. Coal may also fall due to overloading or bumpy roads. Dust will also be caused to spread during unloading, which can easily affect construction workers. Utility Model Content

[0029] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0030] like Figure 1-6 As shown, the unloading mechanism for coal mine transportation includes:

[0031] The material box 1 has two guide rails 8 fixedly mounted on its side walls, a cover plate 9 is provided between the two guide rails 8, a connecting shaft 10 located inside the guide rails 8 is fixedly connected to the side end of the cover plate 9, and the cover plate 9 overlaps the top edge of the material box 1, and a discharge plate 13 for coal unloading is hingedly provided on one side of the material box 1;

[0032] The bottom plate 2 is arranged at the bottom of the material box 1, and a mounting seat 6 is fixedly connected to the surface of the bottom plate 2, and the mounting seat 6 is rotatably connected to one side of the material box 1, and a stabilizing mechanism is installed on the surface of the bottom plate 2 on the other side of the material box 1. A limiting mechanism is provided at the bottom of the bottom plate 2, one side of the limiting mechanism is in contact with the blanking plate 13, and the other side of the limiting mechanism extends to the outside of the bottom plate 2.

[0033] The bottom plate 2 of the material box 1 is provided with a gentle slope surface 24, and the gentle slope surface 24 is distributed correspondingly to the blanking plate 13, and the blanking plate 13 is fitted and connected to the surface of the material box 1, and the bottom side wall of the material box 1 on the other side of the blanking plate 13 is fixedly connected with an extension shaft 7; the surface of the bottom plate 2 is fixedly connected with the armrest 3 and the pad 5 respectively, and the pad 5 is correspondingly arranged under the material box 1 and contacts the bottom surface of the material box 1; the stabilizing mechanism includes a guide plate 4, which is an arc-shaped structure and is fixedly connected to the surface of the bottom plate 2, the guide plate 4 is located between the material box 1 and the armrest 3, and the extension shaft 7 is slidably connected inside the guide plate 4.

[0034] In this technical solution, by setting a gentle slope 24, most of the coal in the material box 1 can be unloaded, and at the same time, the loading capacity will not be affected by the large slope. When in use, the material box 1 is supported by the pad 5 to realize the loading of coal, and the handrail 3 is used to push the bottom plate 2 and the material box 1 to move to realize coal mine transportation. After unloading through the unloading plate 13, the material box 1 rotates on the bottom plate 2, so that the material box 1 rotates around the mounting seat 6 to allow the residual coal to continue to be discharged, ensuring complete unloading, and no subsequent cleaning of the residue is required, thereby improving ease of use.

[0035] The guide rail 8 is a U-shaped structure and is located at the top of the material box 1. Two cover plates 9 spliced ​​together are provided on the top of the material box 1, and the side ends of the cover plates 9 are fixedly connected to the handles 11; the middle part of the guide rail 8 is fixedly connected to the top of the material box 1 through a limit rod 23, and the surfaces of the material box 1 on both sides of the limit rod 23 are respectively provided with cover plates 9, and the connecting shafts 10 at the side ends of the cover plates 9 are located on both sides of the limit rod 23. The other side of the cover plate 9 is threadedly connected to a screw rod 12, and the screw rod 12 extends to the inner wall of the material box 1.

[0036] In this technical solution, when loading, the screw 12 is unscrewed to separate it from the inner wall of the material box 1, and then the handle 11 is pulled to pull the cover 9 to both sides, so that it drives the connecting shaft 10 to rotate inside the guide rail 8. When the connecting shaft 10 moves to the corner of the guide rail 8, the cover 9 is placed in a vertical position and moved downward, thereby realizing the opening of the cover 9, and the loading operation is performed at this time. When the loading is completed, the cover 9 is pushed upward and the two cover plates 9 are fitted together. At this time, the connecting shaft 10 is limited by the limit rod 23, and then the screw 12 is tightened to move the end to the inside of the material box 1, restricting the outward movement of the cover 9, thereby realizing the closure of the top of the material box 1, avoiding the problem of coal and dust being discharged during transportation, and improving the protection performance.

[0037] The bottom edge of the bottom plate 2 is rotatably connected to the roller 14, and a discharge port 15 corresponding to the discharge plate 13 is opened on one side of the bottom plate 2, and the side ends of the bottom plate 2 on both sides of the discharge port 15 are fixedly connected to the limit plate 16; the limiting mechanism includes a connecting seat 17, a rotating shaft 18 and a push rod 19, the connecting seat 17 is fixedly connected to the bottom of the bottom plate 2, and the interior of the connecting seat 17 is rotatably connected to the rotating shaft 18, one end of the rotating shaft 18 is fixedly connected to the push rod 19, and the push rod 19 contacts the bottom of the discharge plate 13; the push rod 19 is located inside the limit plate 16 of the U-shaped structure, one end of the rotating shaft 18 is fixedly connected to the rocker arm 20, and the top of the rocker arm 20 is rotatably connected to the handle 21; two limit shafts 22 are fixedly connected to the side wall of the material box 1, and the limit shafts 22 are correspondingly arranged above the rocker arm 20 of the bending structure.

[0038] In this technical solution, the roller 14 is used to move the bottom plate 2 to facilitate the transportation of coal. When unloading, the handle 21 is lifted upward to drive the rocker 20 to rotate. The rocker 20 drives the shaft 18 to rotate inside the connecting seat 17, so that the shaft 18 drives the push rod 19 to rotate. The push rod 19 rotates to both sides and separates from the unloading plate 13. At this time, the coal is discharged from the material box 1 and discharged from the unloading port 15. At this time, the rocker 20 is located below the limit shaft 22. When most of the coal is discharged, continue to rotate the handle 21 to make the rocker 20 contacts the limit shaft 22 and pushes it upward. The limit shaft 22 drives the material box 1 to rotate around the mounting seat 6 so that all the coal on the gentle slope 24 is discharged. When the material box 1 rotates, the limit rod 23 slides on the surface of the rocker arm 20 and stops when it contacts the end of the limit rod 23, so that the limit can be achieved. After the unloading is completed, the material box 1 is rotated to the pad 5 for support. At this time, the discharge plate 13 is in a vertical position due to its own weight. Continue to rotate the handle 21 to drive the push rod 19 to press against the discharge plate 13, thereby achieving the closing of the discharge plate 13.
