[0038] Among them, the plurality of slats include a surrounding slat 111 and a limiting slat 112, and the ore discharge port 101 is surrounded by the surrounding slats 111 and the limiting slat 112. Specifically, the surrounding slats 111 are used to surround the wide side of the ore discharge port 101, and the limiting slat 112 cooperates with the surrounding slats 111 to surround the long side of the ore discharge port 101. The position distribution state of the ore discharge port 101 is adjusted by moving the position of the limiting slat 112, thereby simulating the influence of factors such as the position of the ore discharge port 101 on the ore discharge efficiency, and providing accurate design guidance for mine mining design; in this embodiment, the surrounding slats 111 are used to surround the wide side of the ore discharge port 101, and the limiting slat 112 cooperates with the surrounding slats 111 to surround the long side of the ore discharge port 101. The position distribution state of the ore discharge port 101 is adjusted by moving the position of the limiting slat 112, thereby simulating the influence of factors such as the position of the ore discharge port 101 on the ore discharge efficiency, and providing accurate design guidance for mine mining design. The cross-sections of 11 and the limiting slats 112 are both rectangular, so that the surrounding slats 111 and the limiting slats 112 can be placed stably on the beam 102. When the position distribution of the ore discharge port 101 needs to be changed, it is only necessary to move one or more limiting slats 112 on the left to the right, and at the same time, the position of the surrounding slats 111 is also moved to the left by the width of one or more limiting slats 112, or move one or more limiting slats 112 on the right to the left, and at the same time, the position of the surrounding slats 111 is also moved to the right by the width of one or more limiting slats 112.

The limiting slats 112 can also be composed of a plurality of shorter slat structures spliced ​​together. In this embodiment, the limiting slats 112 are an integrated longer slat structure design, which is convenient for shifting and placing.

[0040] Furthermore, the height of the enclosing slats 111 is consistent with the height of the limiting slats 112 to ensure the flatness of the upper surface of the bottom panel 110 and avoid the unevenness of the bottom panel 110 affecting the test effect of ore placement; in addition, the width of the enclosing slats 111 is consistent with the width of the limiting slats 112, and the width of the bottom panel 110 is an integer multiple of the width of the enclosing slats 111 or the width of the limiting slats 112 to facilitate the placement of the enclosing slats 111 and the limiting slats 112, so that the enclosing slats 111 and the limiting slats 112 can form a complete bottom panel 110 structure after they are placed.

[0041] In one embodiment, a plurality of fixing holes are opened on the beam 102, and a plurality of positioning holes are also opened on the bottom ends of the surrounding slats 111 and the bottom ends of the limiting slats 112. The bolts pass through the fixing holes and are clamped in the positioning holes, thereby firmly fixing the surrounding slats 111 and the limiting slats 112 on the beam 102.

[0042] In one embodiment, the model box 100 also includes a steel bracket 120 and a transparent wear-resistant tempered plastic baffle 130. The steel bracket 120, the baffle 130 and the bottom panel 110 are arranged to form the overall structure of the model box 100. The model box 100 as a whole is a square cylindrical structure. The overall frame corresponding to the steel bracket 120 is formed by welding to ensure the stability of the structure of the model box 100.

[0043] Furthermore, the steel bracket 120 includes a plurality of vertically arranged pillars 121 and a cross bar 122 arranged on the periphery of the bottom panel 110. A first card slot is provided on the side of the pillar 121, and a second card slot 1221 is provided on the cross bar 122. The periphery of the baffle 130 is correspondingly clamped in the first card slot and the second card slot 1221, thereby realizing the fixed assembly operation of the baffle 130.

[0044] In one embodiment, the cross bar 122 is arranged in the middle of the support 121, so that the bottom panel 110 of the model box 100 is at a distance from the ground, which facilitates the ore in the model box 100 to fall out of the ore discharge port 101 without hindering the subsequent fall of ore in the model box 100, thereby facilitating the present invention to simulate the influence of factors such as the position of the ore discharge port 101 on the ore discharge efficiency, and provide accurate design guidance for mine mining design.

[0045] In one embodiment, the crossbeam 102 is fixed on the crossbar 122. Specifically, the crossbeam 102 is fixed to the crossbar 122 by welding, thereby ensuring the stability of the connection between the crossbeam 102 and the crossbar 122, and ensuring that sufficient support can be provided for the ore in the model box 100; the crossbeam 102 is a sheet structure, thereby ensuring that the slats can be firmly placed on the crossbeam 102, and will not cause the problem of tilting due to unstable center of gravity; in this embodiment, the number of crossbeams 102 is 4, which are respectively arranged at the two end edges and the middle of the bottom panel 110. In addition, the design size of the crossbeam 102 must also be based on not blocking the ore discharge port 101, so as to ensure that the ore discharge ports 101 in different positions can fully simulate the impact on the ore discharge efficiency, thereby providing accurate design guidance for mine mining design.

[0046] In one embodiment, a reinforcing column 123 is provided between two adjacent pillars 121, and the reinforcing column 123 is fixedly connected between the two adjacent pillars 121 by welding, thereby ensuring the stability of the steel support 120 structure; specifically, the reinforcing column 123 is provided on the outer wall of the baffle 130, effectively avoiding the reinforcing column 123 being designed on the inner wall of the baffle 130 and interfering with the simulation results of the ore falling of the present invention.

[0047] In one embodiment, a camera 200 is provided at the upper end of the steel support 120 above the baffle 130. The camera 200 is used to record the ore discharge process in the model box 100. When the stacking form of the ore in the model box 100 no longer changes, it can be known that the ore in the ore discharge test device of the present invention is in a blocked state or the end time of ore discharge can be known, and then the optimal ore discharge design can be determined by comparing the ore discharge rate and blockage conditions obtained at different ore discharge ports 101 positions, thereby providing accurate design guidance for mine mining design.

[0048] Furthermore, a support rod 141 is provided at the upper end of the steel bracket 120 in parallel above the baffle 130. Specifically, the two ends of the support rod 141 are respectively connected to the two adjacent pillars 121, and a fixed rod 142 is connected between the two support rods 141. The camera 200 is fixed on the fixed rod 142 to record the ore discharge process of the ore in the model box 100. When the stacking form of the ore in the model box 100 no longer changes, it can be known that the ore in the ore discharge test device of the present invention is in a blocked state or the end time of ore discharge can be known, and then the optimal ore discharge design can be determined by comparing the ore discharge rate and blockage conditions obtained at different ore discharge port 101 positions, thereby providing accurate design guidance for mine mining design.

[0049] In one embodiment, the model box 100 is fixedly provided with a ore discharge funnel 300 at the ore discharge port 101, and the height of the bottom panel 110 is greater than the height of the ore discharge funnel 300 itself, so that the bottom of the ore discharge funnel 300 still maintains a distance from the ground, so that the ore in the model box 100 will not be blocked at the bottom of the ore discharge funnel 300 after flowing out through the ore discharge funnel 300 and affect the subsequent falling of ore, thereby facilitating the present invention to simulate the influence of factors such as the position of the ore discharge port 101 on the ore discharge efficiency, and provide accurate design guidance for mine mining design.

[0050] In one embodiment, the side of the ore-discharging funnel 300 is a trapezoidal structure, and the ore-discharging port of the upper end of the ore-discharging funnel 300 gradually becomes smaller to the lower end of the ore-discharging funnel 300. A limiting plate 310 is protruding outward from the side of the ore-discharging port of the upper end of the ore-discharging funnel 300, and the limiting plate 310 is fixed on the bottom panel 110; specifically, the limiting plate 310 is fixed on the slats, and further, the limiting plate 310 is fixed on the surrounding slats 111. As the surrounding slats 111 shift, the limiting plate 310 also shifts synchronously, thereby ensuring the stability of the ore-discharging funnel 300 fixed on the bottom panel 110; when the ore in the model box 100 falls from the ore-discharging port 101 into the ore-discharging funnel 300, and then slowly falls to the ground along the inner wall of the ore-discharging funnel 300, it is convenient for the present invention to simulate the influence of factors such as the position of the ore-discharging port 101 on the ore-discharging efficiency, and provide accurate design guidance for mine mining design.

[0051] In one embodiment, a gasket funnel 400 is provided in the ore-discharging funnel 300. The side of the gasket funnel 400 is a trapezoidal structure. The slope of the inner wall of the gasket funnel 400 is greater than the slope of the inner wall of the ore-discharging funnel 300. By placing gasket funnels 400 corresponding to inner walls with different slopes in the ore-discharging funnel 300, the slope angle of the ore when it falls can be adjusted, which can simulate the influence of inner walls with different slopes on the ore-discharging efficiency, thereby providing accurate design guidance for mine mining design; in addition, the gasket funnel 400 is designed to be a detachable structure, and there is no need to replace the model box 100 as a whole. It is only necessary to replace the gasket funnels 400 with inner walls with different slopes separately to simulate the influence of different slope angles on the ore-discharging efficiency, thereby providing accurate design guidance for mine mining design.

[0052] Furthermore, a fixing plate 410 is protruding outward from the upper end of the gasket funnel 400, and openings 401 / 301 are provided on the fixing plate 410 and the limiting plate 310. The gasket funnel 400 is firmly fixed on the ore-discharging funnel 300 by bolts; specifically, the bolts pass through the openings 401 / 301 to connect the gasket funnel 400 and the ore-discharging funnel 300 together and then are fixed on the bottom panel 110, thereby realizing the fixing operation of the ore-discharging funnel 300 and the gasket funnel 400.

[0053] When assembling a mineral drawing test device according to the present invention, after the steel bracket 120 is welded and fixed together, the surrounding slats 111 and the limiting slats 112 are combined according to the design of the preset mineral drawing port 101 using the supporting effect of the crossbeam 102 to form a bottom panel 110 structure; in order to further simulate the influence of different inner wall slopes on the mineral drawing efficiency, the mineral drawing funnel 300 with the gasket funnel 400 is fixed to the bottom panel 110 by bolts, and then the baffle 130 is fixed to the steel bracket 120 to form a complete model box 100 structure, and finally the ore particles are poured into the model box 100, thereby simulating the mineral drawing test process; then, by moving the surrounding slats 111 and the limiting slats 112 to change the position of the mineral drawing port 101, replacing the gasket funnel 400 with different inner wall slopes and placing it in the mineral drawing funnel 300, the influence of factors such as the position of the mineral drawing port 101 and the inner wall slope on the mineral drawing efficiency is simulated, thereby providing accurate design guidance for mine mining design.
