Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment technology, and in particular to an automatic unloading mechanism for a coal hopper car. Background Technology

[0002] Coal hopper cars are important equipment for transporting bulk materials and are widely used in railways, mines and ports. Their core function is to enable the rapid unloading of materials such as coal through the bottom hopper structure, thereby improving transportation and loading / unloading efficiency.

[0003] Traditional coal hopper cars are usually opened manually, with the doors opened manually to unload the coal, or a crane is used to lift the coal and dump it out. Both methods require frequent manual intervention and adjustment, which not only increases the risk of operation but also reduces unloading efficiency.

[0004] To address the above issues, we have developed an automatic unloading mechanism for coal hopper cars. Utility Model Content

[0005] This utility model discloses an automatic unloading mechanism for a coal hopper car, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic unloading mechanism for a coal hopper car includes a car body. A discharge chute is provided on one side of the car body. Inclined rods are fixedly connected at equal intervals above the discharge chute inside the car body. An inclined groove with the same inclination as the inclined rods is provided at the bottom of the car body. Limiting protrusions are fixedly connected at equal intervals on the inclined groove. A baffle is provided above the inclined rods. A limiting groove is provided at the bottom of the baffle to cooperate with the limiting protrusions. The baffle slides with the inclined rods through the cooperation between the limiting groove and the limiting protrusions.

[0008] The vehicle body is equipped with a positioning mechanism for fixing the baffle.

[0009] The vehicle body is equipped with an adjustment mechanism for adjusting the baffle.

[0010] The baffle has symmetrical adjustment grooves on one side, and toothed plates are fixedly connected inside each adjustment groove. The baffle is connected to the adjustment mechanism through the toothed plates.

[0011] In a preferred embodiment, the adjusting mechanism includes a rotating shaft and gears. A groove is provided inside the vehicle body, and the groove communicates with an inclined groove. The rotating shaft is rotatably connected inside the groove. Sliding sleeves are symmetrically slidably connected to the outside of the rotating shaft. The gears are fixedly connected to the outside of the corresponding sliding sleeves. A keyway and a flat key structure for limiting the position are provided between the sliding sleeves and the rotating shaft. The gears are all used in conjunction with corresponding gear plates.

[0012] In a preferred embodiment, an adjusting rod is rotatably connected between the two sliding sleeves, a through groove is provided on one side of the vehicle body, the through groove communicates with the groove body, and one end of the adjusting rod extends to the outside of the vehicle body through the through groove.

[0013] In a preferred embodiment, a drive slot is provided inside the vehicle body, and a drive motor is installed inside the drive slot. The output end of the drive motor extends into the interior of the slot and is connected to a rotating shaft.

[0014] In a preferred embodiment, the positioning mechanism includes a hydraulic press unit and a wedge block. A blocking groove is provided inside the vehicle body, and the blocking groove communicates with the inclined groove. The hydraulic press unit is installed inside the blocking groove, and the wedge block is installed on the output end of the hydraulic press unit. The wedge block is used in conjunction with a baffle.

[0015] In a preferred embodiment, a sealing flange is bolted to the inside of the discharge trough.

[0016] The automatic unloading mechanism for a coal hopper car provided by this utility model has the following advantages:

[0017] This device uses a hydraulic unit to drive a wedge block to contact the bottom of a baffle, achieving baffle limiting when fully loaded. During unloading, the hydraulic unit retracts, and the baffle moves downward along the inclined rod under pressure, exposing the gap between the inclined rod and allowing coal particles to automatically flow into the discharge chute through the gap. After unloading, pulling the adjusting rod engages the gear and toothed plate inside the sliding sleeve, driving the motor to rotate the rotating shaft. The gear rotation drives the baffle to rise and reset, covering the inclined rod to form a bearing surface. Subsequently, the gear and toothed plate separate, and the hydraulic unit pushes the wedge block against the baffle to complete positioning. The entire process requires no manual intervention, achieving automatic unloading and resetting of the coal hopper car, significantly reducing labor intensity and improving operational efficiency.

A discharge chute 2 is provided on one side of the car body 1. Inclined rods 3 are fixedly connected at equal intervals inside the car body 1 and above the discharge chute 2. An inclined groove 4 with the same inclination as the inclined rod 3 is provided at the bottom of the car body 1. Limiting protrusions 5 are fixedly connected at equal intervals on the inclined groove 4. A baffle 6 is provided above the inclined rods 3. A limiting groove 7 is provided at the bottom of the baffle 6 to cooperate with the limiting protrusions 5. The baffle 6 is slidably connected to the inclined rods 3 through the cooperation between the limiting groove 7 and the limiting protrusions 5.

[0029] The interior of the vehicle body 1 is equipped with a positioning mechanism for fixing the baffle 6;

[0030] The interior of the vehicle body 1 is equipped with an adjustment mechanism for adjusting the baffle 6;

[0031] A symmetrical adjustment groove 8 is provided on one side of the baffle 6. A toothed plate 11 is fixedly connected inside the adjustment groove 8. The baffle 6 is connected to the adjustment mechanism through the toothed plate 11.

[0032] In this embodiment, coal is loaded inside the vehicle body 1 by placing a baffle 6 on a diagonal bar 3, and the baffle 6 and the vehicle body 1 are used to load the coal.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, the adjustment mechanism includes a rotating shaft 13 and a gear 15. A groove 12 is provided inside the vehicle body 1, which communicates with the inclined groove 4. The rotating shaft 13 is rotatably connected inside the groove 12. Sliding sleeves 14 are symmetrically slidably connected to the outside of the rotating shaft 13. The gear 15 is fixedly connected to the outside of the corresponding sliding sleeve 14. A keyway and a flat key structure for limiting are provided between the sliding sleeve 14 and the rotating shaft 13. The gears 15 are used in conjunction with the corresponding toothed plates 11. An adjustment rod 16 is rotatably connected between the two sliding sleeves 14. A through groove 10 is provided on one side of the vehicle body 1, which communicates with the groove 12. One end of the adjustment rod 16 extends to the outside of the vehicle body 1 through the through groove 10. A drive groove 17 is provided inside the vehicle body 1. A drive motor 18 is installed inside the drive groove 17. The output end of the drive motor 18 extends into the groove 12 and is connected to the rotating shaft 13.

[0034] In this embodiment: In actual use, firstly, pull the adjusting rod 16, which drives the sliding sleeve 14 to move, so that the gear 15 inside the sliding sleeve 14 moves along the rotating shaft 13, and the gear 15 slides into the toothed plate 11, so that the gear 15 meshes with the toothed plate 11. Then, by starting the drive motor 18, the drive motor 18 drives the rotating shaft 13 to rotate, so that the gear 15 can be rotated. The rotation of the gear 15 drives the baffle 6 to rise, so that the baffle 6 covers the inclined rod 3 to form a bearing surface.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, the positioning mechanism includes a hydraulic unit 20 and a wedge block 21. A blocking groove 19 is provided inside the vehicle body 1. The blocking groove 19 communicates with the inclined groove 4. The hydraulic unit 20 is installed inside the blocking groove 19. The wedge block 21 is installed on the output end of the hydraulic unit 20. The wedge block 21 is used in conjunction with the baffle 6.

[0036] In this embodiment, the hydraulic unit 20 is composed of multiple hydraulic cylinders. The hydraulic unit 20 drives the wedge block 21 to move, so that the wedge block 21 contacts the bottom surface of the baffle 6. This allows the baffle 6 to be pressed against and thus limit its movement, ensuring that the baffle 6 will not move even under full load. In the unloading state, the hydraulic unit 20 only needs to perform a return stroke. The baffle 6 will be pressed and move along the inclined rod 3, thus exposing the inclined rod 3. The coal particles can then flow into the discharge chute 2 through the gap between the two inclined rods 3.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, a sealing flange 9 is bolted to the inside of the discharge trough 2;

[0038] In this embodiment, when no material is being discharged, the discharge chute 2 can be sealed by installing the sealing flange 9 to ensure that the material will not spill out.

[0039] Working principle: In actual use, the hydraulic unit 20 drives the wedge block 21 to move, so that the wedge block 21 contacts the bottom surface of the baffle 6, thus abutting the baffle 6 and limiting its movement. This ensures that the baffle 6 will not move even under full load. During unloading, the hydraulic unit 20 simply returns, and the baffle 6 moves along the inclined rod 3 under pressure, exposing the inclined rod 3. Coal particles can then flow into the discharge chute 2 through the gap between the two inclined rods 3. After unloading, the adjusting rod 16 is pulled, which drives the sliding sleeve 1. 4. Move the gear 15 inside the sliding sleeve 14 along the rotating shaft 13, so that the gear 15 slides into the toothed plate 11, and the gear 15 meshes with the toothed plate 11. Then, start the drive motor 18, and drive the rotating shaft 13 to rotate, so that the gear 15 can be rotated. The rotation of the gear 15 drives the baffle 6 to rise, so that the baffle 6 covers the inclined rod 3 to form a bearing surface. Then, pull the adjusting rod 16 to separate the gear 15 from the toothed plate 11. Finally, control the hydraulic unit 20 to make the wedge block 21 abut against the bottom of the baffle 6 to achieve positioning.

[0040] It should be noted that the adjusting rod 16 can be positioned by drilling holes and installing screws, depending on the actual use. The screws will contact the surface of the vehicle body 1 to achieve the positioning of the adjusting rod 16.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
