[0047] The adjustable ore discharge bin 1 includes a square bin and four... Figure 3 The telescopic bracket shown is one Figure 5 The removable baffle shown, one Figure 4 The adjustable ore discharge bin 1, as shown, consists of a pull-out base plate and an inclined baffle. Four telescopic supports are located at the four corners of the bottom of the square bin. The detachable baffle is fixed inside the bin via slots. The pull-out baffle is located inside the square bin's base plate, and the inclined baffle is fixed to the bottom of the square bin, directly below the rectangular ore discharge opening. The aforementioned adjustable ore discharge bin 1 utilizes the telescopic supports and detachable baffle to adjust the bin to the required inclination, inclination angle, segment height, ore discharge step distance, and ore discharge opening size for the experiment. Specifically, the adjustable ore discharge bin 1 is adjusted by changing the height of the four supports to obtain the required inclination, inclination angle, and height for the experiment, and by assembling and disassembling the detachable baffle and pull-out base plate to change the thickness and ore discharge opening size.

[0048] The arch-breaking device 2 is fixed at the bottom of the adjustable ore discharge bin 1 near the ore discharge port. After receiving the striking command, the arch-breaking device 2 releases its elastic force to strike the ore discharge port, causing the blocking particles to continue to be discharged. Then, it tightens its elastic force to return to the initial state.

[0049] The conveyor belt 3 has protective baffles on both sides, connecting the end of the inclined baffle at the bottom of the adjustable ore discharge bin to the inlet of the storage bin. The conveyor belt transports the particles discharged from the adjustable ore discharge bin to the storage bin.

[0050] The flow control plate 4 is composed of two rectangular baffles, as shown in Figure 2 The two rectangular baffles are opened at a certain angle, and the diameter that can be passed through is reduced, so that the particles pass through in order under the action of the conveying belt 3, and the number of particles passing through each time is controlled to be 1.

[0051] The impedance analyzer 5 is fixed on the conveying belt 3 and located behind the flow control plate 4 in the direction of the particle flow, and is fixed on the protective baffle on both sides of the conveying belt, as shown in Figure 6 The bottom of the impedance analyzer 5 has two soft probes, and the soft probes are fixed at a height of 1 / 2 of the protective baffle above the conveying belt.

The storage bin 6 is used to store particles that have passed through the impedance analyzer 5, and the particles reach the designated position under the action of gravity. The above-mentioned designated position is the position of the baffle in front of the inclined guide rail 8.

Whether the ore bin is filled is detected by measuring the change of the laser reflection distance, and a feedback signal is fed back to the computer control center 10. The laser detector two is fixed at a height of 1 / 2 of the protective baffle on one side of the conveying belt 3, located between the flow control plate 4 and the impedance analyzer 5. Whether there are particles continuing to pass through is detected by measuring the change of the laser reflection distance within a certain time, and a feedback signal is fed back to the computer control center 10.

After multiple repeated measurements, the non-intersecting allowable error interval between any particles is determined according to the median floating range. The particles within the measured allowable error interval are classified into the same category and assigned a unique ID, thereby achieving quick identification of the conductivity of the particles.

[0060] An indoor automatic ore release experimental simulation system can completely release the particles in the adjustable ore release bin 1 and completely store them in the storage bin 6, and then perform a new round of filling and placing operation to realize automatic and repeated experiments under the same parameters and modes.

[0061] The system can completely release the particles in the adjustable ore release bin 1, so when the system is used for experiments, the particles used do not need to be separately distinguished as waste rock and ore. The three-dimensional graph of the recorded particle ID, coordinates and release order obtained by the experiment is used to demarcate the boundary between waste rock and ore, and the release shape is obtained according to the release order and coordinates.

[0066] Step 4: The impedance spectrum of each particle is converted into a feature vector in the computer control center, and a unique ID is assigned according to the specified allowable error interval. If the ID has a corresponding coordinate value, record the coordinate value and the release order, and display it in the three-dimensional graph. If the ID has no corresponding coordinate value, it is not returned;

[0067] Step 5: In the order of X→Y→Z positive direction, that is, taking any one corner of the four corners of the square warehouse as the origin, a Cartesian coordinate system is established to include the square warehouse of the adjustable ore bin in the first quadrant. The coordinate values corresponding to the ID are rearranged in the order of length, width, and depth of the warehouse body;

[0068] Step 6: After passing through the impedance analyzer, the particles enter the storage bin in turn under the action of the spiral track and are stored upward and pass through the inclined guide rail in turn to reach the designated position;

[0069] Step 7: After all the particles enter the storage bin, if the experiment is to be ended, the information stored in the computer control center is emptied, and all the particles are taken out. If the experiment is to continue, the three-dimensional graph information recorded in the computer control center is saved, and the three-dimensional graph is initialized;

[0070] Step 8: The computer control center controls the mechanical linkage device to grab the particles at the designated position at the outlet of the storage bin and places them in the adjustable ore bin according to the corresponding coordinate values rearranged in step 5.

[0071] Step 9: The segmented height, inclination, inclination angle, and ore discharge opening size of the adjustable ore bin are adjusted according to the experimental design scheme;

[0072] Step 10: Steps 2 to 8 are repeated to repeat the experiment and obtain the three-dimensional graph results of each experiment.
