Description

Technical Field

[0001] The invention belongs to the field of ore sorting, and in particular relates to an ore sorting device used for geological mining. Background Art

[0002] The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials.

[0003] After the ore is mined, it must go through multiple processes before it can be used. However, during the mining process, the ores obtained are of different sizes. The ore needs to be sorted according to the size before it can be processed later. In order to save time, workers will use sorting devices to sort the ore.

[0004] However, during sorting, workers will pour all the ore into the sorting device at once, and then start the machine for sorting. Because too much ore is poured in at one time and the volume of the sorting device is fixed, the excess ore will be stacked together, and only the ore at the bottom of the ore pile can be filtered by the filter screen, while the small particles of ore above the ore pile will be blocked by the large particles of ore below, making it impossible to filter and sort. The only option is to extend the filtration path, disperse and flatten the ore pile, and finally allow small particles of ore to pass through the filter screen. This method will increase the sorting time, reduce the sorting efficiency, and also reduce the sorting effect. Summary of the invention

[0005] The purpose of the present invention is to provide an ore sorting device for geological mining, aiming to solve the technical problem of low sorting efficiency in the prior art.

When the circulation mechanism continues to operate, the linkage mechanism is used to drive the rotating shaft to rotate back and forth, so that the rotating shaft drives the roller screen and the filter net to rotate back and forth. The reciprocating rotation angle range of the roller screen and the filter net is -70°~70°, which avoids the filter net flipping 180°, thereby causing the ore on the filter net to fall into the first collecting box, thereby making the ore screening more accurate.

Therefore, the circulation mechanism further includes a first reverse transmission mechanism, which is connected between the two second drive rods and is used to make the two second drive rods rotate synchronously in opposite directions. The linkage mechanism is installed between the two second driving rods and the rotating shaft.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1-Figure 10 As shown, an ore sorting device for geological mining provided by the present invention comprises a box body 1, a roller screen 6 is rotatably installed inside the box body 1, a feeding cavity and a collecting cavity are respectively provided on the upper and lower sides of the roller screen 6, the feeding cavity is connected with the collecting cavity only through the roller screen 6, a first collecting box 2 is provided inside the collecting cavity, the roller screen 6 is a hollow truncated cone, a plurality of filter holes are provided on the surface of the hollow truncated cone, the axis of the roller screen 6 is horizontally arranged, a filter screen 7 is fixedly connected to the inside of the roller screen 6, and the roller screen 6 is provided with a filter screen 7. The aperture of the filter screen 7 is smaller than that of the roller screen 6. The filter screen 7 is tilted toward the small-diameter end of the roller screen 6. The side of the box body 1 is provided with a first discharge port 3 connected to the bottom end of the filter screen 7. The side of the box body 1 close to the small-diameter end of the roller screen 6 is provided with a second discharge port 11 connected to the feed cavity. The top of the box body 1 close to the large-diameter end of the roller screen 6 is provided with a feed port 4 connected to the feed cavity. The large-diameter end of the roller screen 6 is fixedly connected to a rotating shaft 5, and the rotating shaft 5 is rotatably mounted on the box body 1. The box 1 is provided with a circulation mechanism, which includes two circulation components, which are symmetrically distributed about the roller screen 6. The circulation components are used to transport large particles of ore at the bottom of the ore pile to the top of the ore pile, so that small particles of ore at the top fall onto the roller screen 6, so that they can also contact the roller screen 6 and be filtered and screened by the roller screen 6, thereby shortening the sorting time and improving the sorting efficiency. A linkage mechanism 15 is connected between the circulation mechanism and the rotating shaft 5. When the circulation mechanism continues to operate, the linkage mechanism 15 is used to drive the rotating shaft 5 to rotate back and forth, so that the rotating shaft 5 drives the roller screen 6 and the filter screen 7 to rotate back and forth. The angle range of the reciprocating rotation of the roller screen 6 and the filter screen 7 is -70°~70°, which avoids the filter screen 7 from flipping 180°, thereby causing the ore on the filter screen 7 to fall into the first collecting box 2, thereby making the ore screening more accurate.

[0032] When the roller screen 6 rotates, the ore in contact with the outer surface of the roller screen 6 will also be moved by the roller screen 6, and the roller screen 6 will break up the ore pile, so that the ore slides along the surface of the roller screen 6, and the small particles of ore will pass through the roller screen 6 and fall onto the filter screen 7, and the large particles of ore will slide downward along the surface of the roller screen 6 under the action of gravity and be discharged from the second discharge port 11, so as to realize the sorting of large particles of ore and small particles of ore; Since the filter screen 7 is tilted, when the filter screen 7 rotates, the small particles of ore will slide along the filter screen 7, and the ore slag contained in the small particles of ore will pass through the filter screen 7 and the roller screen 6 in turn and fall into the first collecting box 2, thereby realizing the sorting of small particles of ore and ore slag.

[0033] like Figure 2-Figure 4 As shown, an ore sorting device for geological mining provided by the present invention, in this embodiment, the circulation component includes a drop channel 12 and a return channel 10, the drop channel 12 and the return channel 10 are both opened on the side of the upper material chamber, the drop channel 12 is set obliquely downward, and the opening of the drop channel 12 contacts the surface of the rolling screen 6, the return channel 10 is set obliquely upward, and the return channel 10 is located above the drop channel 12, the circulation component also includes an installation cavity 13, the return channel 10 and the drop channel 12 are both connected to the installation cavity 13, a feeding mechanism 9 is installed inside the installation cavity 13, the feeding mechanism 9 is used to transport the ore sliding from the drop channel 12 to the return channel 10, and then the ore slides from the return channel 10 into the upper material chamber, when the ore at the bottom of the ore pile slides into the drop channel 12, the ore at the top of the ore pile will fall down and contact the rolling screen 6, so that it continues to be filtered by the rolling screen 6, thereby improving the sorting effect.

[0034] like Figure 2-Figure 3 and Figure 7-10 As shown, an ore sorting device for geological mining provided by the present invention is provided. In this embodiment, the feeding mechanism 9 includes a second driving rod 96 rotatably mounted on the box body 1, and one end of the second driving rod 96 located inside the installation cavity 13 is fixedly connected to a first transmission roller 91, and a second transmission roller 94 is also rotatably mounted inside the installation cavity 13, and a conveyor belt 92 is transmission-connected between the second transmission roller 94 and the first transmission roller 91, and a plurality of equally spaced material transport plates 93 are fixedly connected to the surface of the conveyor belt 92; In order to make the ore on the material transport plate 93 fall into the return channel 10, a material discharge comb 95 is fixedly connected to the side of the return channel 10, and the material discharge comb 95 is arranged obliquely downward, and the end of the material discharge comb 95 contacts the surface of the conveyor belt 92. Each of the material transport plates 93 is provided with a plurality of comb slots 97 for the material discharge comb 95 to pass through, and the plurality of comb slots 97 are equidistantly distributed on the material transport plate 93; The circulation mechanism further includes a motor 17, which is fixedly mounted on the side of the box body 1, and the output shaft of the motor 17 is fixedly connected to one end of a second driving rod 96 extending out of the box body 1; Since the two circulation components are symmetrically arranged, the movement directions of the two circulation components need to be opposite to each other in order for the whole device to operate smoothly. Therefore, the circulation mechanism further includes a first reverse transmission mechanism 14, which is connected between the two second drive rods 96. The first reverse transmission mechanism 14 is used to make the two second drive rods 96 rotate synchronously in the opposite direction. The linkage mechanism 15 is installed between the two second driving rods 96 and the rotating shaft 5 .

[0035] The motor 17 drives the second driving rod 96 to rotate, the second driving rod 96 drives the first driving roller 91 to rotate, the first driving roller 91 drives the conveyor belt 92 to move, and the conveyor belt 92 drives the transport plate 93 to move. When the ore slides from the blanking channel 12 to the inside of the installation cavity 13, the ore will fall onto the transport plate 93, and the transport plate 93 drives the ore to rise. When the transport plate 93 contacts the unloading grate 95, as the transport plate 93 continues to drive the ore to rise, the ore will be squeezed by the inclined surface of the unloading grate 95, so that the ore will gradually move to the return channel 10. When the transport plate 93 completely passes through the unloading grate 95, the ore on the transport plate 93 will be squeezed down by the unloading grate 95, causing the ore to fall into the return channel 10, and then under the action of gravity, the ore slides back into the loading cavity to complete the ore circulation. Specifically, refer to Figure 3 As shown, for the feeding mechanism 9 on the left side of the rolling screen 6, the motor 17 will drive it to rotate counterclockwise, and when the ore slides from the drop channel 12 into the installation cavity 13, the ore will fall onto the transport plate 93 on the right side of the feeding mechanism 9, and the transport plate 93 will drive the ore to rise. When the ore moves to the return channel 10, since there is no longer any obstruction on the right side of the ore, the upper layer of the ore pile on the transport plate 93 will roll into the return channel 10, and the lower layer of the ore pile in contact with the transport plate 93 will encounter the unloading grate 95. Since the shape of the ore is irregular, the end of the unloading grate 95 will squeeze the edge of the ore, and under the squeezing of the inclined surface of the unloading grate 95, the ore on the transport plate 93 is squeezed into the return channel 10, so that the ore returns to the loading cavity again; Similarly, for the feeding mechanism 9 on the right side of the roller screen 6, the motor 17 will drive it to rotate clockwise, and the ore will slide from the drop channel 12 to the transport plate 93 on the left side of the feeding mechanism 9. The transport plate 93 will drive the ore to rise. When the ore encounters the discharge grate 95, the discharge grate 95 will squeeze the ore into the return channel 10, so that the ore returns to the loading chamber.

[0036] like Figure 2-Figure 4 and Figure 9-10 As shown, an ore sorting device for geological mining provided by the present invention is provided. In this embodiment, a plurality of the circulation mechanisms can be provided, and the plurality of the circulation mechanisms are distributed along the cross-sectional edge line of the rolling screen 6, but the motor 17 and the second driving rod 96 in the circulation mechanism can share one.

[0037] like Figure 9-10As shown, an ore sorting device for geological mining provided by the present invention, in this embodiment, the first reverse transmission mechanism 14 includes a first rotating rod 142 rotatably installed on the side of the box body 1, a first transmission pair 141 is connected between the first rotating rod 142 and a second driving rod 96, a second transmission pair 143 is connected between the first rotating rod 142 and another second driving rod 96, the first transmission pair 141 is a sprocket pair, and the second transmission pair 143 is a gear pair.

[0038] like Figure 2-Figure 4 and Figure 7-10 As shown, an ore sorting device for geological mining provided by the present invention is provided. In this embodiment, the linkage mechanism 15 includes two second rotating rods 152, and the two second rotating rods 152 are rotatably installed on the side of the box body 1, and are respectively arranged on both sides of the rotating shaft 5. A driving gear 154 is fixedly connected to the rotating shaft 5, and an incomplete gear 153 is fixedly installed on the two second rotating rods 152. The two incomplete gears 153 can be meshed with the driving gear 154, and the two incomplete gears 153 are not meshed with the driving gear 154 at the same time. The second rotating rod 152 is transmission-connected to the second driving rod 96 on the same side through the third transmission pair 151.

[0039] When the second driving rod 96 rotates, the second driving rod 96 drives another second driving rod 96 to rotate in the opposite direction through the first reverse transmission mechanism 14. The two second driving rods 96 respectively drive the two second rotating rods 152 to rotate in the opposite direction and synchronously through the third transmission pair 151. The two second rotating rods 152 drive the two incomplete gears 153 to rotate, so that the incomplete gear 153 can drive the driving gear 154 to rotate. Since the rotation directions of the two incomplete gears 153 are opposite, the directions in which different incomplete gears 153 drive the driving gear 154 to rotate are also opposite. When the second driving rod 96 continues to rotate, the driving gear 154 drives the rotating shaft 5 to rotate reciprocatingly, and the rotating shaft 5 drives the rolling screen 6 to rotate reciprocatingly.

[0040] like Figure 2-Figure 6As shown, an ore sorting device for geological mining provided by the present invention, when the rolling screen 6 drives the ore at the bottom of the ore pile to flow into the drop channel 12, the ore on the top of the ore pile will scatter. Since the drop channel 12 is always in an open state, part of the fallen ore will fall into the drop channel 12 on the other side, causing a part of the small-particle ore to circulate, reducing the sorting efficiency. Therefore, in this embodiment, the circulation component also includes a blocking mechanism 8, which is installed in the drop channel 12. When the rolling screen 6 drives the ore away from the drop channel 12, the blocking mechanism 8 is used to close the drop channel 12, thereby preventing the small-particle ore on the top of the ore pile from falling into the drop channel 12.

[0041] like Figure 2-Figure 6 and Figure 9-11 As shown, an ore sorting device for geological mining provided by the present invention is provided. In this embodiment, the material blocking mechanism 8 includes a first driving rod 82 rotatably mounted on the box body 1, and a material blocking plate 84 is installed at one end of the first driving rod 82 located inside the material dropping channel 12. A limiting block 81 adapted to the material blocking plate 84 is fixedly connected to the side wall of the feeding cavity, and the limiting block 81 prevents the material blocking plate 84 from rotating into the feeding cavity to avoid the material blocking plate 84 from getting stuck. The material blocking mechanism 8 further includes a second reverse transmission mechanism 16 , which is connected between the first driving rod 82 and the rotating shaft 5 . The rotating shaft 5 can drive the first driving rod 82 to rotate in the reverse direction through the second reverse transmission mechanism 16 .

[0042] When the rotating shaft 5 drives the ore to rotate toward the material drop channel 12 through the rolling screen 6, the rotating shaft 5 also drives the first driving rod 82 to rotate in the opposite direction through the second reverse transmission mechanism 16, and the first driving rod 82 drives the baffle plate 84 to rotate, thereby opening the material drop channel 12, so that the ore can slide into the material drop channel 12; when the rolling screen 6 drives the ore away from the material drop channel 12, the rotating shaft 5 drives the first driving rod 82 and the baffle plate 84 to block the material drop channel 12 through the second reverse transmission mechanism 16, so as to prevent the ore falling from the top of the ore pile from sliding into the material drop channel 12, thereby preventing the sorting efficiency from being reduced.

[0043] like Figure 2-Figure 6 and Figure 9-11As shown, an ore sorting device for geological mining provided by the present invention is provided. When the first driving rod 82 directly drives the baffle plate 84 to rotate, the baffle plate 84 will rotate synchronously with the rotating shaft 5. In the process of the rolling screen 6 driving the ore away from the material drop channel 12, the baffle plate 84 will slowly close, which will allow part of the ore to enter the material drop channel 12, which will still reduce the sorting efficiency. In this embodiment, the baffle plate 84 is rotatably installed on the first driving rod 82, and a round shell 83 is fixedly connected to the baffle plate 84. A clockwork spring 85 is installed inside the round shell 83. One end of the clockwork spring 85 is fixedly connected to the first driving rod 82, and the other end of the clockwork spring 85 is provided with a limiting protrusion 87. A plurality of limiting semi-grooves 86 that are compatible with the limiting protrusion 87 are opened on the inner side wall of the round shell 83, and the limiting protrusion 87 and the limiting semi-groove 86 are clamped.

[0044] When the rotating shaft 5 drives the first driving rod 82 to rotate through the second reverse transmission mechanism 16, the first driving rod 82 drives the clockwork spring 85 to rotate, and the clockwork spring 85 drives the round shell 83 and the baffle plate 84 to rotate. When the baffle plate 84 is blocked by the top wall of the blanking channel 12, the first driving rod 82 can continue to drive the clockwork spring 85 to rotate, so that the clockwork spring 85 drives the limiting protrusion 87 to disengage from the limiting half groove 86 and get stuck in the next limiting half groove 86, so that the baffle plate 84 can be quickly opened to allow ore to enter; when the rolling screen 6 drives the ore away from the blanking channel 12, the first driving rod 82 will first drive the baffle plate 84 to rotate through the clockwork spring 85, so that the baffle plate 84 is quickly closed to prevent subsequent small particles of ore from falling into the blanking channel 12, thereby improving the sorting efficiency.

[0045] like Figure 9-11 As shown, an ore sorting device for geological mining provided by the present invention, in this embodiment, the second reverse transmission mechanism 16 includes a fixing frame 164 fixedly connected to the side of the box body 1, a universal joint 165 is rotatably installed on the fixing frame 164, one end of the universal joint 165 is fixedly connected to the end of the first driving rod 82 extending out of the box body 1, and a third rotating rod 162 is also rotatably installed on the side of the box body 1, a fifth transmission pair 163 is transmission-connected between the third rotating rod 162 and the universal joint 165, a fourth transmission pair 161 is transmission-connected between the third rotating rod 162 and the rotating shaft 5, the fifth transmission pair 163 is a gear pair, and the fourth transmission pair 161 is a sprocket pair.

[0046] The rotating shaft 5 drives the third rotating rod 162 to rotate through the fourth transmission pair 161 , the third rotating rod 162 drives the universal joint 165 to rotate in the opposite direction through the fifth transmission pair 163 , and the universal joint 165 drives the first driving rod 82 to rotate in the opposite direction.

[0047] Working principle: Pour the ore raw material into the feeding chamber from the feeding port 4, and start the motor 17, the motor 17 drives the second driving rod 96 to rotate, the second driving rod 96 drives the material conveying plate 93 to circulate, and at the same time, the second driving rod 96 drives the rotating shaft 5 and the roller screen 6 to reciprocate through the linkage mechanism 15, and the roller screen 6 drives the ore at the bottom of the ore pile to reciprocate; Small particles of ore in the ore pile will pass through the roller screen 6 and fall onto the filter screen 7, and large particles of ore will slide along the surface of the roller screen 6 toward the small diameter end of the roller screen 6. When the rotating shaft 5 opens the baffle plate 84 through the second reverse transmission mechanism 16, the large particles of ore will also slide into the drop channel 12, and then the transport plate 93 transports the ore to the return channel 10. The large particles of ore will then slide from the return channel 10 to the top of the ore pile. After the ore at the bottom of the ore pile slides into the drop channel 12, the ore at the top of the ore pile will fall onto the surface of the roller screen 6, so that it is filtered by the roller screen 6, thereby improving the filtering effect. The large particles of ore that slide to the small-diameter end of the roller screen 6 will be discharged from the second discharge port 11, and the ore that falls on the filter screen 7 will be filtered by the filter screen 7. The ore slag passes through the filter screen 7 and the roller screen 6 in turn and falls into the first collecting box 2, while the ore on the filter screen 7 will slide along the surface of the filter screen 7 and slide out from the first discharge port 3, thereby realizing the sorting of ore particles of different sizes, which is convenient for the subsequent processing of the ore.
