Description

Technical Field

[0001] This utility model relates to the field of unattended weighing devices, and more specifically, to an unattended weighing device for mines. Background Technology

[0002] A mine refers to an independent production and operation unit that extracts ore within a defined mining boundary. A mine mainly includes one or more mining workshops and some auxiliary workshops. Most mines also include ore dressing plants. When transporting ore, it is necessary to weigh the ore trucks to control the weight of the ore. Unmanned weighing devices have functions such as automatic vehicle identification and intelligent gate control, reducing manual intervention and lowering the company's labor costs. Companies only need to perform regular maintenance and management of the system, without needing to assign dedicated personnel for weighing operations. The system can complete vehicle weighing and generate relevant data in a short time, significantly shortening weighing time and improving work efficiency compared to traditional manual weighing. However, during the weighing of ore trucks, spillage often occurs. If the spilled material on the weighing platform is not cleaned up in time, it will lead to inaccurate weighing data for subsequent vehicles. Therefore, we propose an unmanned weighing device for mines. Utility Model Content

[0021] Please see Figure 1-4An unattended weighing device for mines includes a platform 1, a weighing platform 2 fixedly connected to the top of the platform 1, two second sliding grooves 15 respectively opened at both ends of the top surface of the weighing platform 2, and two second sliding rods 16 slidably connected to the inner cavities of the four second sliding grooves 15. A scraper 17 is fixedly connected between every two second sliding rods 16. A weighbridge 23 is installed on the top of the weighing platform 2, and the bottom surface of the scraper 17 is in contact with the top surface of the weighbridge 23. First sliding grooves 12 are opened on both sides of both ends of the weighing platform 2, and the inner cavities of the four first sliding grooves 12 are rotatably connected to the second sliding rods 16. A threaded rod 14 is provided, and a first slide rod 13 is threadedly sleeved on the outer side of the first threaded rod 14. The end of the first slide rod 13 extends to the outer side of the weighing platform 2 and is connected to the second slide rod 16. A first transmission groove 18 is provided inside both ends of the weighing platform 2. A first rotating shaft 19 is rotatably connected to the inner cavity of the first transmission groove 18. The two ends of the first rotating shaft 19 are respectively connected to the ends of the two first threaded rods 14. A first bevel gear 20 is fixedly sleeved on the outer side of the first rotating shaft 19. A drive mechanism 30 is provided inside the weighing platform 2.

[0022] For details, please refer to Figures 1 to 4 The drive mechanism 30 includes a second transmission groove 24 opened inside the weighing platform 2 and two second rotating shafts 25 rotatably connected inside the weighing platform 2. A servo motor 29 is fixedly installed in the inner cavity of the second transmission groove 24. The output shaft of the servo motor 29 is fixedly connected to a third rotating shaft 27. A fourth bevel gear 28 is fixedly sleeved at the end of the third rotating shaft 27. One end of each of the two second rotating shafts 25 extends into the inner cavity of the second transmission groove 24 and is fixedly sleeved with a third bevel gear 26. The two third bevel gears 26 mesh with the fourth bevel gear 28 respectively. The other end of each of the two second rotating shafts 25 extends into the inner cavity of the first transmission groove 18 and is fixedly sleeved with a second bevel gear 22. The second bevel gear 22 meshes with the first bevel gear 20.

[0023] In this embodiment, the servo motor 29 drives the third rotating shaft 27 and the fourth bevel gear 28 to rotate. The meshing transmission between the fourth bevel gear 28 and the two third bevel gears 26 drives the two second rotating shafts 25 to rotate in opposite directions. The two second rotating shafts 25 drive the two second bevel gears 22 to rotate in opposite directions. The meshing transmission between the two second bevel gears 22 and the two first bevel gears 20 drives the two first rotating shafts 19 to rotate in the same direction, thereby driving the four first threaded rods 14 to rotate in the same direction. The threaded engagement between the first threaded rods 14 and the first slide rods 13 drives the first slide rods 13 to move outward, thereby driving the second slide rods 16 and the scraper 17 to move outward, so that the scraper 17 can clean up the material falling from the top of the weighing platform 2.

[0024] For details, please refer to Figure 1A vehicle identifier 4 is fixedly installed on the top of the platform 1. Two vehicle barriers 5 are fixedly installed on the top of the platform 1. An installation rod 7 is fixedly installed on the top of the platform 1. A horn 8 is installed inside the installation rod 7. A weighing computer 9 is fixedly installed on the top of the installation rod 7.

[0025] In this embodiment, the vehicle identifier 4 can identify the license plate of the mining truck, and then transmit the data wirelessly to the control terminal. The control terminal then activates the vehicle stop 5 to allow the mining truck to drive onto the top of the weighbridge 23. After weighing, the control terminal can activate another vehicle stop 5 to allow the mining truck to pass. Through the cooperation of the infrared transmitter 6 and the horn 8, the driver is reminded by sound alarm when the mining truck does not stop on the top of the weighbridge 23.

[0026] For details, please refer to Figure 1 An ID card reader 3 is fixedly installed on the top of the platform 1.

[0027] In this embodiment, the ID card reader 3 can identify the driver's ID card and transmit the information wirelessly to the control terminal for recording.

[0028] For details, please refer to Figure 1 Two sets of infrared transmitters 6 are fixedly installed on the top of the platform 1.

[0029] In this embodiment, two sets of infrared transmitters 6 can assist the driver in parking the ore truck on top of the weighbridge 23.

[0030] For details, please refer to Figure 1 The platform 1 has two corresponding placement slots 10 inside, and a collection hopper 11 is inserted into the placement slot 10.

[0031] Working principle: When the driver drives the ore truck to platform 1, the vehicle identification device 4 can identify and record the license plate. Simultaneously, the driver places their ID card on the outside of the ID card reader 3. The ID card reader 3 identifies the ID card information of the ore truck and then transmits the data wirelessly to the control terminal. The control terminal then activates the vehicle stop 5 to allow the ore truck to pass. When the ore truck enters the weighing platform 2, two sets of infrared transmitters 6 can locate the truck's position. If the ore truck does not stop at the top of the weighbridge 23, the control terminal can activate an alarm via horn 8 to remind the driver. After weighing the ore truck, the control terminal activates another vehicle stop 5 (this is existing technology and will not be elaborated further). After the ore truck leaves, the control terminal activates the servo... Motor 29 drives the third rotating shaft 27 and the fourth bevel gear 28 to rotate. The meshing transmission between the fourth bevel gear 28 and the two third bevel gears 26 drives the two second rotating shafts 25 to rotate in opposite directions. The two second rotating shafts 25 drive the two second bevel gears 22 to rotate in opposite directions. The meshing transmission between the two second bevel gears 22 and the two first bevel gears 20 drives the two first rotating shafts 19 to rotate in the same direction, thereby driving the four first threaded rods 14 to rotate in the same direction. The threaded engagement between the first threaded rods 14 and the first sliding rods 13 drives the first sliding rods 13 to move outward, thereby driving the second sliding rods 16 and the scraper 17 to move outward, so that the scraper 17 can clean up the material falling from the top of the weighing platform 2, and at the same time improve the accuracy of weighing subsequent vehicles.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
