Abstract
Description
Technical Field
[0001] This utility model is specifically a ore metering system, which relates to the field of mining technology. Background Technology
[0002] After ore is mined, it needs to be weighed and its grade tested. Currently, ore weighing and grade testing are done separately, and the results are recorded and compiled manually, a lengthy process that prevents mine managers from obtaining timely information about the ore's output. With technological advancements, especially in ore grade testing equipment, it is now possible to combine ore weighing and grade testing, allowing for simultaneous measurement and recording. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model discloses an ore output metering system, the purpose of which is to solve the problem that mine managers cannot obtain ore output information in a timely manner in the prior art.
[0004] The present invention adopts the following technical solution: A ore output metering system includes a mine car and an electronic weighbridge, an electric hoist, and a tipping platform located near the ore pass. The tipping platform has an unloading chute, on which an X-ray ore grade inspection device is installed. The electronic weighbridge is used to measure the weight of the ore in the mine car. The electric hoist works in conjunction with the tipping platform to tip the mine car and pour the ore onto the unloading chute, so that the ore can be inspected by the X-ray ore grade inspection device before entering or leaving the ore pass.
[0005] Further improvements to the technical solution: The front and rear ends of the mine car have push bars, and the tilting platform has a slot for locking the front push bar of the mine car; the electric hoist has a hook for hooking the rear push bar of the mine car, so that the mine car tilts towards the unloading chute.
[0006] Further improvements to the technical solution: Radio frequency electronic tags are installed on the mining trucks, and the ore output metering system also includes an electronic tag reader / writer, which is used to read and write the information in the radio frequency electronic tags on the mining trucks.
[0007] Further improvement to the technical solution: The electronic tag reader / writer is positioned above the electronic weighbridge.
[0008] Further improvements to the technical solution: The ore output metering system also includes a remote control unit, which is connected to an electronic tag reader, electronic weighbridge, and X-ray ore grade inspection equipment via a wireless network to automatically record and statistically analyze ore output.
[0009] Further improvement of the technical solution: The X-ray ore grade inspection equipment has an X-ray generator and an X-ray receiver, wherein the X-ray generator is set above the unloading chute and the X-ray receiver is set below the unloading chute.
[0010] Further improve the technical solution: A discharge baffle is installed above the discharge chute to control the flow rate of ore poured onto the discharge chute.
[0011] After implementing the above technical solution, the beneficial effects of this utility model compared to the prior art are: This utility model's ore metering system combines ore weighing, grade inspection, and mine cars, enabling simultaneous measurement, recording, and statistical analysis of ore production in each mining area, significantly improving the automation level and information management level of mining.

[0019] A mineral output metering system, relating to the field of mining technology, is mainly used to solve the problem in the background art where mine managers cannot obtain timely information on mineral output. The composition and working principle of this utility model are described in detail below.
[0020] See attached document Figure 1 The ore output metering system of this utility model includes a mine car 1 and an electronic weighbridge 2, an electric hoist 4, and a tilting table 5, which are installed near the ore chute 8. Among them, the electronic weighbridge 2 is existing technology, which can remove the weight of the mine car 1 itself and only measure the weight of the ore in the mine car 1, and display the weight of the ore in digital form.
[0021] See attached document Figure 2 Unlike existing mining cars, mining car 1 has a front push bar 1.1 at the front end and a rear push bar 1.2 at the rear end. An RFID tag 1.3 is fixed to mining car 1. The RFID tag 1.3 is existing technology; it is bound to mining car 1 and can record when and in which mining area the mining car 1 loaded ore.
[0022] To facilitate ore extraction management, an electronic tag reader 3 is installed above the electronic weighbridge 2. When the mine car 1 is weighed, the electronic tag reader 3 can read the information in the RFID tag 1.3 on the mine car 1 and write the new information into the RFID tag 1.3. In this way, the ore extraction metering system can know when and in which mining area the mine car 1 loaded the ore.
[0023] See attached document Figure 3A tilting table 5 is located at the edge of the ore pass 8. The tilting table 5 has a slot 5.1 for locking the front push bar 1.1 of the mine car 1, and also has an unloading chute 5.2 that tilts towards the ore pass 8. An X-ray ore grade testing device is installed on the unloading chute 5.2. The X-ray ore grade testing device has an X-ray generator 6 and an X-ray receiver 7. The X-ray generator 6 is located above the unloading chute 5.2, and the X-ray receiver 7 is located below the unloading chute 5.2. This X-ray ore grade testing device is a state-of-the-art device that uses X-rays to inspect ore grade. Its greatest advantage is its ability to batch test ore grades and display the results in real time.
[0024] See attached document Figure 1 and attached Figure 4 An electric hoist 4 is fixed above a tilting platform 5. The electric hoist 4 works in conjunction with the tilting platform 5 to tilt the mine car 1, dumping the ore onto the unloading chute 5.2. This allows the ore to be inspected by an X-ray ore grade testing device before entering and exiting the mine pass 8. Specifically, the electric hoist 4 has a hook. During unloading, the hook hooks onto the rear push bar 1.2 of the mine car 1, and the wire rope is retracted, causing the mine car 1 to tilt towards the unloading chute 5.2, dumping the ore onto it. To control the flow rate of ore dumped onto the unloading chute 5.2, an unloading baffle 5.3 is installed above the unloading chute 5.2. As the ore rolls on the unloading chute 5.2, an X-ray generator 6 emits X-rays to irradiate the ore. The X-rays penetrate the ore and are received by an X-ray receiver 7, forming an image. The ore grade can then be detected in real time through a transmission image analysis system. After testing, the ore is dropped into the ore chute 8 via the unloading chute 5.2, completing the ore extraction process.
[0025] See attached document Figure 5 The ore output metering system also features a remote control unit. This unit connects wirelessly to the electronic tag reader / writer (3), electronic weighbridge (2), and X-ray ore grade inspection equipment to automatically record and statistically analyze ore output. This allows mine managers to obtain timely information on ore output, such as the weight of ore extracted from a particular mining area in a day, the ore grade, and the logistics scheduling of the mining trucks (1). Based on this information, mine managers can then make production adjustments.
[0026] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
