[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 As shown, a bottom-discharge mine car unloading station includes:

[0032] The load-bearing pallet 1 is the main body of the device and is used for unloading and storing ore. Supporting rollers 2 are provided on all four sides of the load-bearing pallet 1.

[0033] Electronic control structure 3, installed on the outside of the load-bearing pallet 1, is used to control the operation of the device; electronic control structure 3 includes:

[0034] The intelligent controller 301 is embedded inside the control mounting slot opened on one side of the load-bearing tray 1;

[0035] Control switches 302 are respectively installed at one corner of the load-bearing tray 1 and are electrically connected to the intelligent controller 301. Control switches 302 include, but are not limited to, inductive switches and push-button switches.

[0036] The bottom-discharge mine car unloading station uses a load-bearing pallet 1 as its main body, which can not only bear the weight and collect the ore to realize the unloading function, but also has support rollers 2 on its four sides to assist in stable operation. The electronic control structure 3 is installed on the outside of the load-bearing pallet 1 to control the operation of the device. The intelligent controller 301 embedded in the control mounting slot is the core. The induction switch, push button switch and other control switches 302 are set in one corner of the load-bearing pallet 1 and electrically connected to the intelligent controller 301, which can send signals to the intelligent controller 301. In use, by operating the control switch 302, the intelligent controller 301 receives the signal and controls the device to complete the ore unloading and other related operations.

[0037] Rotating rollers 4 are located on the lower surface of the four corners of the load-bearing pallet 1, and hub motors 5 are installed inside each rotating roller 4; the supporting rollers 2 are connected to the load-bearing pallet 1 by means of a fuma wheel for mutual rotation.

[0038] Rotating rollers 4 are provided on the lower surface of the four corners of the load-bearing pallet 1, and hub motors 5 are installed in each wheel. This allows the device to move flexibly and can be driven and adjusted autonomously as needed. At the same time, the four sides of the load-bearing pallet 1 are connected to the support rollers 2 through rotatable trolleys. The rotatable trolleys have good support and flexibility, can adapt to different ground conditions, and facilitate the device's turning. The electronic control structure 3 is installed on the outside of the load-bearing pallet 1. The intelligent controller 301 is embedded in the control mounting groove. The induction switch, push button switch, and other control switches 302 at one corner of the load-bearing pallet 1 are electrically connected to the intelligent controller 301. In use, the operation of the control switch 302 sends a signal. After receiving the signal, the intelligent controller 301 controls the operation of the hub motors 5 and other components, thereby realizing the movement of the device and the precise unloading of the ore.

[0039] The shifting roller 6 is rotatably installed at the center of the load-bearing pallet 1, and a drive motor 7 for moving the load-bearing pallet 1 is installed inside it; the upper end of the shifting roller 6 is designed with a rotating connecting shaft, and a rotating mounting groove is opened on the lower surface of the load-bearing pallet 1. A connecting bearing 601 is fixedly installed inside the rotating mounting groove, and the rotating connecting shaft is fixedly connected to the inside of the connecting bearing 601.

[0040] In this bottom-discharge mine car unloading station, the shifting roller 6 is a key component that assists in the flexible movement and position adjustment of the device. It is rotatably installed at the center of the load-bearing pallet 1 and has a drive motor 7 inside, which provides power to push the load-bearing pallet 1 to move. The rotating connecting shaft at its upper end is connected to the connecting bearing 601 fixedly installed in the rotating mounting groove on the lower surface of the load-bearing pallet 1, so that the shifting roller 6 can rotate flexibly relative to the load-bearing pallet 1. In use, the drive motor 7 inside the shifting roller 6 is started through the electronic control structure 3. Under the power drive, the shifting roller 6 moves the entire device. At the same time, its flexible rotation characteristic allows the device to easily change direction and achieve precise shifting at different positions to meet the unloading needs of ore at different locations.

[0041] The U-shaped guide rail 8 is used to guide the shifting roller 6 to move in a predetermined direction. The lower surface has a positioning mounting threaded hole, and a fixing bolt 9 is set inside the mounting threaded hole. Limiting grooves are opened on both sides of the interior of the U-shaped guide rail 8, and the two sides of the shifting roller 6 are located inside the limiting grooves. There is a gap between the center position of the shifting roller 6 and the interior lower surface of the U-shaped guide rail 8 to prevent it from contacting the fixing bolt 9.

[0042] The U-shaped guide rail 8 plays a crucial role in the precise guidance and stable positioning of this bottom-discharge mine car unloading station. The threaded holes on its lower surface, combined with the fixing bolts 9, ensure the guide rail is securely installed in the designated position. The limiting grooves on both sides of the interior effectively constrain the shifting roller 6, ensuring it can only move in a predetermined direction and preventing deviation. During use, the shifting roller 6 is placed inside the U-shaped guide rail 8, with the limiting grooves embedded on both sides, and a gap between the center position and the lower surface of the guide rail to prevent contact with the fixing bolts 9 and subsequent wear. When the drive motor 7 of the shifting roller 6 starts and the device moves, the U-shaped guide rail 8, with its own structure and limiting design, guides the shifting roller 6 along the set route, ensuring the entire unloading station can accurately reach different workstations for ore unloading operations.

[0043] Storage frame 10, designed around the load-bearing tray 1, is used to prevent ore from slipping off; storage frame 10 includes:

[0044] The fixed middle plate 1001 is designed at the center of the four sides of the load-bearing pallet 1 and is welded and fixed to the load-bearing pallet 1.

[0045] The curved corner plate 1002 is welded and fixed to the four corners of the load-bearing pallet 1;

[0046] The operating baffle 1003 is installed on both sides of the fixed middle plate 1001 and hinged to the load-bearing pallet 1.

[0047] The operating baffle 1003 is designed with fixed lugs on both sides, and a fixed threaded hole is opened in the center of the fixed lug. The fixed threaded holes at both ends pass through the fixed middle plate 1001 and the arc-shaped corner plate 1002 respectively, and the connecting bolt 1004 is installed in the internal thread of the fixed threaded hole.

[0048] The storage frame 10 is designed around the load-bearing tray 1 to effectively prevent ore from slipping during unloading, ensuring operational safety and site cleanliness. Its fixed middle plate 1001 is welded to the center of the four sides of the load-bearing tray 1, providing stable support for the frame. The arc-shaped corner plates 1002 are fixed at the four corners to enhance the overall structural strength of the frame and prevent ore from spilling out from the corners. The operating baffle 1003 is hinged between the fixed middle plate 1001 and the load-bearing tray 1 on both sides, and can rotate flexibly. When in use, if it is necessary to open the load-bearing tray 1 for unloading or cleaning, the connecting bolts 1004 can be unscrewed and the operating baffle 1003 can be lowered. If it is necessary to block ore, the operating baffle 1003 can be raised so that the fixing threaded holes of the fixing lugs are aligned with the fixing middle plate 1001 and the arc-shaped corner plates 1002, and then the connecting bolts 1004 can be screwed in to fix it. The operation is simple and practical.
