[0029] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses that the auxiliary unloading device 5 includes two mounting blocks 51, and the two mounting blocks 51 are fixedly connected to the surfaces of the two curved rail bodies 3 respectively. The surfaces of the two mounting blocks 51 close to each other are rotatably connected with a rotating rod 52, and two connecting plates 53 are fixedly connected to the arc surface of the rotating rod 52. The surfaces of the two connecting plates 53 are fixedly connected with hammer rods 54, and one end of the rotating rod 52 is fixedly connected with a first gear 55. The surface of the curved rail body 3 close to the first gear 55 of the two curved rail bodies 3 is fixedly connected with a servo motor 56, and the output end of the servo motor 56 is fixedly connected with a second gear 57. The first gear 55 is meshed with the second gear 57. When the mine car passes the unloading station 1 for unloading, the drive motor 4 on the unloading station 1 will start, driving the mine car to move forward, and the body Supported by the supporting wheel 2 of the unloading station 1, the unloading wheel in the middle of the rear wheel of the mine car rolls along the curved track body 3, and the door falls at the same time, so that the ore is unloaded. At this time, the servo motor 56 on one side of the curved track body 3 is started. The rotation of the servo motor 56 will start the second gear 57 on its output end to rotate back and forth. Because the first gear 55 on the rotating rod 52 is engaged with it, the rotating rod 52 will rotate back and forth on the mounting block 51. At this time, the hammer rod 54 on the connecting plate 53 will repeatedly hit the opened door. At this time, the ore attached to the door will fall off and be discharged. At this time, when the unloading station 1 is unloading the ore from the mine car, the ore can be unloaded more quickly and the inner wall of the door is not easily attached to the ore, which reduces the carrying efficiency and collection efficiency of the ore and improves the working efficiency and practicality of the unloading station 1.
[0030] Reference Figure 1 and Figure 2 as well as Figure 3As shown, this embodiment discloses that the inner walls of the two mounting blocks 51 are respectively fixedly connected with bearings 58, the outer ring of the bearing 58 is fixedly connected to the inner wall of the mounting block 51, and the inner ring of the bearing 58 is fixedly connected to the arc surface of the rotating rod 52. Through the setting of the bearing 58, the wear between the two is reduced when the rotating rod 52 rotates on the mounting block 51, thereby making the rotation of the rotating rod 52 more stable and less prone to shaking, so that the car door can be hit stably, ensuring the stable unloading of the mine car, and the surfaces of the two connecting plates 53 are respectively provided with slots 59. The surfaces of the two curved rail bodies 3 are fixedly connected with the same limit plate 510, and the limit plate 510 is plugged into the inner wall of the slot 59. Through the plug-in setting of the limit plate 510 and the slot 59, when the hammer rod 54 hits the car door, it is not easy for the connecting plate 53 and the hammer rod 54 to rotate excessively, thereby affecting the movement and unloading of the rear mine car and causing damage to the mine car.

Through the setting of the limit frames 511, the connecting plate 53 is not easy to rotate excessively when rotating away from the car door, and the reverse limiting effect is activated, thereby better ensuring that the ore adhering to the car door is knocked down. The surface of the hammer rod 54 is fixedly connected to a protective pad 512, and the protective pad 512 is a rubber pad. Through the setting of the protective pad 512, when the hammer rod 54 repeatedly hits the car door, it is not easy to cause damage to the car door due to excessive knocking force, until the car door is deformed, affecting the subsequent ore transportation.
[0032] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, this embodiment discloses that the protective device 6 includes a mounting plate 61, which is fixedly connected to the surface of the curved rail body 3, and a mounting frame 63 is inserted into the surface of the mounting plate 61, and a protective shell 62 is fixedly connected to the surface of the mounting frame 63.

At this time, when the auxiliary unloading device 5 is in use, the driving components at the position of the servo motor 56 can be protected to a certain extent, and are not easily hit by falling ores, etc., causing damage to the device, thereby causing it to be used abnormally.
[0033] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, this embodiment discloses that the surface of the bolt 64 is fixedly connected with an operating block 65, and the surface of the operating block 65 is provided with a number of anti-slip protrusions.

[0034] Working principle: When the mine car passes the unloading station 1 for unloading, the driving motor 4 on the unloading station 1 will start, driving the mine car to move forward, and the body of the mine car is supported by the supporting wheel 2 of the unloading station 1. The unloading wheel in the middle of the rear wheel of the mine car rolls along the curved track body 3, and the car door falls at the same time, so that the ore is unloaded. At this time, the servo motor 56 on one side of the curved track body 3 is started. The rotation of the servo motor 56 will start the second gear 57 on its output end to rotate back and forth. Because the first gear 55 on the rotating rod 52 is engaged with it, the rotating rod 52 will rotate back and forth on the mounting block 51. At this time, the hammer rod 54 on the connecting plate 53 will repeatedly hit the opened car door. At this time, the ore attached to the car door will fall off and be discharged. At this time, when the unloading station 1 is unloading the ore from the mine car, the ore can be unloaded more quickly, and the inner wall of the car door is not easily attached to the ore, which reduces the carrying efficiency and collection efficiency of the ore and improves the working efficiency and practicality of the unloading station 1.
[0035] When the auxiliary unloading device 5 is assembled, the protective shell 62 is put on the surface of the servo motor 56, and the protective shell 62 covers the surface of the first gear 55 and the second gear 57. At this time, the mounting plate 61 on the curved track body 3 will be inserted into the inner wall of the mounting frame 63 on the surface of the protective shell 62, and then the bolt 64 is inserted through the surface of the mounting frame 63, and the bolt 64 is threadedly connected to the surface of the mounting plate 61 to fix the position of the protective shell 62. At this time, when the auxiliary unloading device 5 is in use, the driving components at the position of the servo motor 56 can be protected to a certain extent, and are not easily hit by falling ores, etc., which may cause damage to the device and cause abnormal use.
