[0025] In some material sorting scenarios, especially for coal and ore, ore sorting machines primarily use X-ray emission to identify ore content and employ a combination of conveyor devices, jet cleaning devices, and hoppers for mineral screening. The conveyor device, such as a conveyor belt, transports the material to the identification device. The identification device uses an X-ray emitter above the belt and a receiver below to detect the material, determining its category for sorting. The sorting device separates the materials based on the identification results, separating different categories. The hopper receives and discharges different categories of material. As the discharge point for the sorting machine, the hopper often experiences material accumulation, such as coal and ore, falling onto the machine frame and hindering equipment maintenance.

[0026] To overcome the problems existing in related technologies, exemplary embodiments of this disclosure provide a silo device for receiving materials sorted by a sorting machine, wherein, for example... Figure 1 , Figures 4 to 7 As shown, the hopper device may include: hopper frame 110, hopper door 120 and material conveying ramp 130.

[0027] 110 hopper frame, such as Figure 1 , Figures 4 to 7 As shown, the shell of the entire silo device, serving as the main frame, can be installed on the silo frame 110. The shell on the side of the silo device facing the material inflow direction is hollow to receive materials. A distribution baffle can be installed at the bottom of the silo device, and the remaining shell is hollow to facilitate material entry, distribution, and discharge for subsequent collection and processing. The silo frame 110 can include multiple sets of horizontal beams and multiple sets of vertical beams. These beams can be integrally formed or fixedly connected by bolts or other means. The silo frame 110 can be made of high-strength steel or alloy materials.

[0028] 120mm hopper door, such as Figure 1 , Figure 6 , Figure 7 As shown, the hopper door 120 can be hinged to one side of the hopper frame 110 and rotates relative to the hopper frame 110 to open and close. Multiple hopper doors 120 can be provided, all of which can be connected to the hopper frame 110. One side of the hopper door 120 can be hinged to the hopper frame 110, and the hopper door 120 can be opened and closed around a pivot. When the hopper door 120 is closed, the sorting machine performs identification, sorting, and material distribution. When the hopper door 120 is open, personnel can perform equipment maintenance.

[0029] Sliding ramp 130, such as Figure 1 , Figure 6 , Figure 7 As shown, a material sliding ramp 130 can be installed on the side of the hopper door 120 facing the inside of the hopper frame 110, and located in the bottom area of ​​the hopper door 120. This ramp guides the material to slide into the hopper frame 110, preventing material accumulation. The material sliding ramp 130, whose main body can be an inclined panel structure, can be installed on the inside of the hopper door 120 and can be connected to the bottom area of ​​the hopper door 120 by bolts or the like. The material sliding ramp 130 can be made of high-hardness steel or alloy material, capable of withstanding material impact. When the hopper door 120 is closed, the material can slide from the material sliding ramp 130 into the inside of the hopper frame 110, away from the hopper door 120 and the hopper frame 110, thereby preventing material adhesion and accumulation at the hopper frame 110.

[0030] In some embodiments, the width of the material conveying ramp 130 is consistent with the width of the hopper door 120. If the width of the material conveying ramp 130 is too wide, it will make it difficult to open and close the hopper door 120. If the width of the material conveying ramp 130 is too narrow, the material may accumulate at the hopper door 120 or at the hopper frame 110, making equipment maintenance more difficult.

[0031] In this embodiment, a hopper device is provided, with a material sliding ramp 130 located at the bottom inner side of the hopper door 120. This ramp guides the material to slide into the interior of the hopper device, preventing material accumulation at the hopper support 110 and the hopper door. This facilitates equipment maintenance by reducing the frequency of manual cleaning due to material retention and lowering maintenance costs. In some cases, the material is coal, ore, etc., which has recycling value, thus increasing the sorting output, saving resources, and improving sorting efficiency.

[0032] In some embodiments, the material conveying ramp 130 is detachably connected to the hopper door 120. One or more bolt holes may be provided on the material conveying ramp 130, through which bolts can be passed to securely connect it to the hopper door 120. After the material conveying ramp 130 wears out and needs to be disassembled, it can be easily replaced. In some embodiments, the material conveying ramp 130 can be connected to the hopper door 120 via a snap-fit ​​connection, pin connection, or the like. In this embodiment, by detachably connecting the material conveying ramp 130 to the hopper door 120 using bolts or the like, replacement or disassembly can be achieved without complex tools. This facilitates the replacement of the material conveying ramp 130 with a suitable one based on different material characteristics, such as viscosity and hardness. Maintenance is convenient, reducing equipment downtime, lowering manual maintenance costs, improving equipment flexibility and application range, and enhancing efficiency.

[0033] In some embodiments, such as Figure 3As shown, the material sliding ramp 130 includes a baffle plate 131, which is disposed in the bottom area of ​​the hopper door 120, and its height can be the same as the bottom installation area of ​​the hopper door 120. Material can slide down along the baffle plate 131 to enter the inner side of the hopper frame 110. The baffle plate 131 may include a first vertical portion 1311, an inclined portion 1312, and a second vertical portion 1313, which can be connected or integrally formed.

[0034] The first vertical part 1311, as shown Figure 3 As shown, it can be fixedly connected to the inner surface of the hopper door 120. The first vertical part 1311 can be a vertical plate structure with bolt holes, which can be fixed to the hopper door 120 by bolts. The lower end of the first vertical part 1311 can be connected to the upper end of the inclined part 1312, or it can be integrally formed.

[0035] Inclined part 1312, such as Figure 3 As shown, the upper end of the inclined portion 1312 can be connected to the lower end of the first vertical portion 1311, and the lower end of the inclined portion 1312 extends inclinedly into the interior of the hopper frame 110. The inclined portion 1312 is the part of the material guiding the material sliding ramp 130, and can be in the form of an inclined plate structure. The upper end of the inclined portion 1312 can be connected to the lower end of the first vertical portion 1311 or integrally formed. The lower end of the inclined portion 1312 extends inward away from the hopper frame 110, and can guide the material into the interior of the hopper frame 110.

[0036] In some embodiments, the angle between the inclined portion 1312 and the horizontal plane can be 60-80 degrees. If the angle is too small, material may remain in the inclined portion 1312. If the angle is too large, the lower end of the inclined portion 1312 will be closer to the hopper frame 110 or the hopper door 120, and the material will still slide down close to the hopper frame 110 or the hopper door 120, causing material accumulation. The angle of the inclined portion 1312 can be 70 degrees. A suitable angle can prevent material from remaining in the inclined portion 1312 and can also prevent material from accumulating at the hopper frame 110 and the hopper door 120.

[0037] The second vertical part 1313, as shown Figure 3 As shown, the upper end of the second vertical portion 1313 can be connected to the lower end of the inclined portion 1312, and the lower end of the second vertical portion 1313 extends downward. The upper end of the second vertical portion 1313 receives the lower end of the inclined portion 1312, and the lower end is vertically downward. When material falls into the inclined portion 1312, it can slide down the inclined portion 1312 under the action of gravity, reach the upper end of the second vertical portion 1313, and slide out from the lower end of the second vertical portion 1313, falling into the internal area of ​​the hopper device.

[0038] In this embodiment, a first vertical part 1311, an inclined part 1312, and a second vertical part 1313 are provided. The first vertical part 1311 can fix the entire baffle plate 131 to the hopper door 120. The inclined part 1312 uses gravity to guide the material to slide into the hopper device. The second vertical part 1313 can smoothly transfer the material to the bottom of the hopper for subsequent operation and processing. This can prevent the material from accumulating at the hopper frame 110 or the hopper door 120, reduce the frequency of manual cleaning, shorten the maintenance downtime, and improve the overall operating efficiency of the equipment.

[0039] In some embodiments, such as Figure 3 As shown, the material sliding ramp 130 may also include: a plurality of vertical plates 132 and at least one horizontal plate 133.

[0040] Multiple uprights 132, such as Figure 3 As shown, vertical plates 132 can be spaced apart on the back side of baffle plate 131, and can be perpendicular to baffle plate 131, at least partially supported by inclined portion 1312. Vertical plates 132 can be cut from steel plate or integrally formed with baffle plate 131. They can be straight plates, and their overall height can be slightly lower than the overall height of the back side of baffle plate 131. Their length can cover the transition area of ​​baffle plate 131 from inclined portion 1312 to second vertical portion 1313. Multiple vertical plates 132 can be arranged at even intervals along the transverse direction of baffle plate 131, covering the main stress-bearing area of ​​baffle plate 131. They can be appropriately densified in areas of concentrated material impact. Vertical plates 132 can be vertically welded to the back side of baffle plate 131, and the welding position can be the contact surface between vertical plate 132 and baffle plate 131. The upright plate 132 can be set at a perpendicular angle to the baffle plate 131. The top of the upright plate 132 can extend to the top of the inclined portion 1312 or slightly below the top of the inclined portion 1312, and the bottom can extend to the bottom of the second vertical portion 1313, which can be used to support the inclined portion 1312.

[0041] At least one horizontal plate 133, such as Figure 3As shown, a horizontal plate 133 can be connected to the side of multiple upright plates 132 away from the inclined portion 1312, and can fix multiple upright plates 132 to the hopper door 120. The horizontal plate 133 can be formed from steel plate and can be in the shape of a long, straight strip. In some embodiments, one horizontal plate 133 can be provided, horizontally arranged on multiple upright plates 132. In other embodiments, multiple horizontal plates 133 can be provided, with a length consistent with the distance between two upright plates 132, used to fix multiple upright plates 132. The width of the horizontal plate 133 can be set according to the support strength. Each horizontal plate 133 can have mounting holes to fix multiple upright plates 132 to the hopper door 120. The horizontal plate 133 can be attached to the back side of multiple upright plates 132 and can be connected to the upright plates 132 by bolts or welding. It can intersect the upright plates 132 perpendicularly. The horizontal plate 133 can connect multiple independent upright plates 132 into an integral frame. The vertical plate 132 can support the baffle plate 131, and the horizontal plate 133 can transfer the force of the vertical plate 132 to the hopper door 120, thus playing a certain supporting role.

[0042] In this embodiment, multiple vertical plates 132 and at least one horizontal plate 133 are provided. The vertical plates 132 are supported on the back side of the baffle plate 131 and fixed to the hopper door 120 by the horizontal plate 133. The multiple vertical plates 132 can enhance the overall rigidity of the baffle plate 131 by supporting it, resisting bending and denting deformation caused by material impact or heavy pressure, and ensuring the structural stability of the inclined part 1312. The frame structure formed by the horizontal plate 133 and the vertical plates 132 enhances the impact resistance of the material sliding ramp 130, increases the service life of the material sliding ramp 130, reduces maintenance steps, improves equipment operation reliability, and reduces maintenance costs.

[0043] In some embodiments, the baffle plate 131 has at least one or more longitudinally extending ribs (not shown in the figure) formed on the outer side of the inclined portion 1312. The ribs can extend longitudinally along the inclined portion 1312, i.e., in the direction of material sliding, and can be elongated protrusions. The cross-section of the ribs can be triangular, trapezoidal, or arc-shaped, etc. The length of a single rib can cover the length region of the inclined portion 1312, and can extend from the upper end of the inclined portion 1312 to the lower end of the inclined portion 1312. One or more ribs can be provided according to the width of the inclined portion 1312, and the multiple ribs can be distributed laterally at intervals along the inclined portion 1312 with uniform spacing. The ribs can be integrally formed with the outer side of the inclined portion 1312.

[0044] In this embodiment, a raised rib is provided on the outer side of the inclined portion 1312, and the longitudinal direction of the rib extends in the same direction as the trajectory of the material naturally sliding down. This guides the material to slide along the channel formed between the raised ribs, ensuring the stability of the material as it slides down. Furthermore, it increases the local thickness and rigidity of the surface of the inclined portion 1312, improving its resistance to bending and impact, and making it particularly suitable for long-term impact from large or hard materials.

[0045] In some embodiments, such as Figure 1 , Figures 4 to 7 As shown, the silo device may also include: a dust removal port 140 and a screen 150.

[0046] Dust collection port 140, such as Figure 1 , Figure 4 , Figure 5 , Figure 7 As shown, a dust collection port 140 can be formed through the top of the silo frame 110 for dust discharge. The dust collection port 140 can be a through-hole structure penetrating the shell at the top of the silo device, and the opening shape can be circular or rectangular. In some embodiments, the shell at the top of the silo frame 110 can extend outward to form a conical surface, with a through-hole at the top of the conical surface serving as the dust collection port 140. The dust collection port 140 can be connected to an external fan via a dust collection pipe, facilitating the fan to draw dust from inside the silo device along the dust collection port 140, preventing dust from spreading inside the silo device. In other embodiments, the dust collection port 140 can be directly formed on the shell at the top of the silo device, without needing to protrude outward.

[0047] 150 mesh screen, such as Figures 4 to 7 As shown, the screen 150 can cover the dust collection port 140 and is connected to the hopper frame 110 to prevent foreign objects from entering the dust collection port 140. The screen 150 can be made of metal. In some embodiments, the dust collection port 140 protrudes from the hopper frame 110, and the screen 150 can be positioned below the dust collection port 140. In other embodiments, the screen 150 can be positioned at the dust collection port 140, completely covering it, ensuring that all dust passing through the dust collection port 140 is filtered by the screen 150, preventing foreign objects such as plastics from entering the dust collection pipeline and clogging the fan. The screen 150 is detachably connected to the hopper frame 110 for easy removal and replacement.

[0048] In this embodiment, by providing a dust removal port 140 at the top of the hopper frame 110 and covering the dust removal port 140 with a screen 150, the dust inside the hopper device is discharged outward, which can intercept foreign objects such as plastics from entering the fan along the dust removal pipe, thereby avoiding blockage of the fan. The structure is simple, easy to disassemble and assemble, and can extend the service life of the equipment.

[0049] In some embodiments, such as Figure 2As shown, the screen 150 may include: a frame 151, multiple long iron plates 152, and a mounting plate 153.

[0050] Frame 151, such as Figure 2 As shown, it can be rectangular or circular, consistent with the shape and size of the dust collection port 140. The width of the frame 151 is moderate, ensuring overall rigidity.

[0051] Multiple long iron plates 152, such as Figure 2 As shown, the long iron plates 152 can be arranged in parallel at intervals on the inner side of the frame 151, and both ends can be connected to the frame 151 respectively. Multiple long iron plates 152 can be made of wear-resistant steel and can be in a straight, elongated shape. The long iron plates 152 can be arranged in parallel at intervals along the inner side of the frame 151, and the uniform spacing can form a uniform interception gap. The two ends of the long iron plates 152 can be fixed to the inner side of the frame 151 by welding.

[0052] Mounting plate 153, such as Figure 2 As shown, the mounting plate 153 can be fixed to the frame 151 for detachable connection to the hopper frame 110. In some embodiments, the mounting plate 153 can be parallel to the long iron plate 152, and can be in the shape of a flat plate, disposed on both sides of the long iron plate 152. Multiple mounting plates 153 can be provided, distributed at intervals along the inner circumference of the frame 151, and there can be two to four, arranged symmetrically. The mounting plate 153 can be provided with mounting holes for detachable connection to the hopper frame 110, which can be a bolt connection. The mounting plate 153 can be rigidly fixed to the frame 151, which can be achieved by welding, ensuring connection strength.

[0053] In this embodiment, a frame 151, multiple long iron plates 152, and a mounting plate 153 are provided. Dust can be discharged outward along the gaps between the long iron plates 152 to the dust removal pipeline, and foreign objects such as plastics can be prevented from being discharged outward and clogging the fan. The long iron plates 152 can be stably fixed to the frame 151 and fixed to the hopper frame 110 by the mounting plate 153, which can effectively intercept foreign objects, reduce the occurrence of dust removal pipeline blockage, fan impeller wear, and other failures caused by foreign objects entering the dust removal pipeline, reduce equipment maintenance costs and downtime frequency, and thus improve material sorting efficiency and sorting output.

[0054] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, the long iron plate 152 can be tilted, with the end closer to the material feeding direction higher than the other end. The tilt direction of the long iron plate 152 matches the material feeding direction, with the end closer to the material falling area (material feeding direction) being the high end and the end farther from the material falling area being the low end. The long iron plate 152 always maintains a stable tilt. This allows dust to follow the airflow when the fan extracts gas, being discharged outward along the side opposite to the material feeding direction without affecting the airflow on the material feeding side, thus achieving positive airflow circulation. The material feeding side (high end of the iron plate) mainly consists of local airflow driven by the falling material, while the dust removal side (low end of the iron plate) is the main exhaust airflow formed by the fan extraction. The tilted setting of the long iron plate 152 ensures that the airflow on the dust removal side (low end of the iron plate) flows unidirectionally to the dust removal port 140, while the airflow on the material feeding side (high end of the iron plate) circulates only around the material falling area.

[0055] In this embodiment of the disclosure, the long iron plate 152 is set at an angle, which can prevent the airflow on the material receiving side (the high end of the iron plate) from being disturbed by dust removal and air extraction, thus avoiding affecting the flight trajectory of the material and the sorting results. This allows the material to be sorted normally, which is beneficial to improving the sorting efficiency and further increasing the sorting output of the material.

[0056] In some embodiments, such as Figure 2 As shown, the screen 150 may further include one or more reinforcing ribs 154, both ends of which can be fixed to the frame 151, and are staggered and fixedly connected to multiple long iron plates 152. The reinforcing ribs 154 can be made of metal steel and can be long and narrow. Their length can be consistent with the transverse dimension of the frame 151. One or more reinforcing ribs can be set according to the size of the screen 150 and the distribution density of the long iron plates 152, and can be distributed along a direction perpendicular to the iron plates 152, with uniform spacing covering the main stress area of ​​the screen 150. The two ends of the reinforcing ribs 154 can be rigidly connected to the inner wall of the frame 151, and can be fixed by welding. The reinforcing ribs 154 can be fixedly connected to multiple long iron plates 152 at the intersection points, using welding or other methods. This ensures that the inclined long iron plates 152 form multi-point support and maintains the stability of the inclination angle.

[0057] In this embodiment, one or more reinforcing ribs 154 are provided to enhance the overall rigidity of the screen 150, prevent the long iron plates 152 from bending or tilting under the impact of materials, maintain the uniformity of the gaps and the stability of the tilt angle of the long iron plates 152, and ensure normal interception of foreign objects. This ensures that the dimensions of the airflow channel (gap between iron plates 152) remain unchanged, and that dust is discharged directionally away from the incoming material direction with the airflow, thus ensuring the stability of the airflow inside the hopper device.

[0058] Based on the same inventive concept, exemplary embodiments of this disclosure also provide a sorting machine that can be used for material sorting, including: a conveying device, an identification device, and a sorting device, such as the silo device in the foregoing embodiments.

[0059] A conveying device can be used to transport materials. The conveying device can be a conveyor belt, etc., which places materials on the belt and transports them to the identification device.

[0060] The identification device can be used to identify materials conveyed by belt conveyors, and can identify the content of ore by emitting X-rays.

[0061] A sorting device is used to sort materials based on the identification results of an identification device. The sorting device can be installed downstream of a belt conveyor and can separate materials according to their category, thus separating different types of materials.

[0062] The hopper device receives and discharges materials sorted by the sorting unit. A material conveyor ramp 130 is installed at the bottom inner side of the hopper door 120 to guide the material into the interior of the hopper device, preventing material accumulation at the hopper support 110 and the hopper door. This facilitates equipment maintenance, reduces the frequency of manual cleaning due to material retention, and lowers maintenance costs. In some cases, where the material is coal, ore, or other materials with recycling value, this device can increase sorting output and efficiency.

[0063] The sorting machine according to the embodiments of this disclosure can transport materials via a belt conveyor, facilitating identification and classification by the identification device. Based on the identification and classification of materials by the identification device, different types of materials are finally sorted by the sorting device, enabling accurate and rapid classification and sorting of the materials to be tested, with high identification and sorting accuracy.

[0064] The silo unit is a key piece of equipment connecting the sorting device and subsequent processing stages. It efficiently receives sorted materials and discharges them in an orderly manner, integrating functions such as load-bearing, flow guidance, and dust removal. The silo unit uses a silo frame 110 as a rigid foundation. The rectangular frame can be composed of columns, beams, and a base plate, providing support for all components and forming a temporary material storage space. A dust removal port 140 is opened at the top, and a hinged, openable silo door 120 is connected to the side. A material sliding ramp 130 can be fixed to the bottom inner side of the silo door 120. This ramp adopts a segmented design, including a first vertical section 1311, an inclined section 1312, and a second vertical section 1313. Combined with the upright plate 132 and horizontal plate 133 on the back side to enhance rigidity, the ramp ensures that materials slide down the slope into the silo, preventing material accumulation. The dust collection port 140 can cover the screen 150. The parallel and spaced inclined strip iron plates 152 in its frame not only intercept foreign objects but also guide the flow of dust. The reinforcing ribs 154 maintain structural stability, and the mounting plate 153 enables a detachable connection with the frame.

[0065] During operation, sorted materials fall into the silo through the feed inlet. The material sliding ramp 130 guides the material further into the silo, and longitudinal ribs further optimize the flow path. Dust generated by the falling material forms a directional airflow under the action of the fan, flowing along the inclined direction of the iron plate 152 of the screen 150 away from the incoming material side, and is discharged through the dust removal port 140, achieving positive airflow circulation. During the discharge phase, the material in the silo is output through the bottom discharge port, and the silo door 120 can be opened for easy cleaning and maintenance. The silo device, through directional flow guidance and rigid structure balance, ensures continuous and efficient material flow, prevents material accumulation at the silo frame 110, can adapt to different material characteristics, reduces maintenance costs, and significantly improves the working environment and operational efficiency.
