[0002] Tungsten concentrate is a high-grade tungsten raw material obtained through beneficiation and enrichment of tungsten ore. Its main component is tungstate minerals, and it is a key raw material for the production of tungsten metal and its alloy products. It is widely used in the manufacture of cemented carbide, special steel, superhard materials, and catalysts. Its unique physicochemical properties, such as high melting point, high density, and good electrical and thermal conductivity, make the processing and production of tungsten concentrate extremely valuable and significant. In the existing technology, when hoisting tungsten concentrate raw materials, the discharge port of the hopper has poor sealing performance, which easily leads to material jamming. During the raw material hoisting process, material spillage occurs, resulting in pollution of the production environment and waste of raw materials. Furthermore, the hopper uses an electronic control method to control the opening and closing of the discharge port, which has high energy consumption and failure rate, affecting production efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a gravity unloading hopper device, which solves the problems in existing technologies where the unloading port of the hopper has poor sealing performance when hoisting tungsten concentrate raw materials, making it easy for material to get stuck. This causes material to spill during the hoisting process, resulting in pollution of the production environment and waste of raw materials. Furthermore, the hopper uses an electronic control method to control the opening and closing of the unloading port, which has high energy consumption and failure rate, affecting production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gravity unloading hopper device, comprising a fixed frame, a hopper fixedly connected to the upper interior of the fixed frame, a discharge ramp fixedly connected to the inner wall of the hopper, a discharge port at the bottom of the discharge ramp, a hoisting hopper connected to the inner wall of the hopper, a load-bearing frame at the bottom of the inner wall of the hoisting hopper, unloading plates movably connected to both sides of the hoisting hopper, the unloading plates being connected to the hoisting hopper and the load-bearing frame, the two unloading plates being rotatably connected at their adjacent sides via a connecting shaft, connecting plates rotatably connected to both ends of the connecting shaft, unloading support rods fixedly connected to the top of the two connecting plates, a connecting rod fixedly connected to the adjacent side of the connecting plates above the connecting shaft, arc-shaped support frames fixedly connected to both sides of the top of the fixed frame, the unloading support rods being connected to the arc-shaped support frames, and rollers rotatably connected to both ends of the unloading plates, the rollers being connected to the load-bearing frame.

[0005] Preferably, the inner wall of the hoisting hopper is provided with sliding grooves on both sides, and a guide block is fixedly connected to the side of the connecting plate away from the connecting rod. The guide block is slidably connected to the sliding groove. The top of both sides of the hoisting hopper is provided with arc-shaped grooves, and the unloading support rod is connected to the arc-shaped grooves. Limiting plates are fixedly connected at equal intervals on both sides of the outer wall of the hoisting hopper. The limiting plates are connected to the hopper. Vertical plates are provided at equal intervals on the top of the hopper. Guide inclined plates are provided on the top of the vertical plates.

[0008] Preferably, a rubber pad is fixedly connected to the bottom of the limiting plate, and the rubber pad is connected in conjunction with the hopper.

[0009] This utility model provides a gravity unloading hopper device. This gravity unloading hopper device offers the following advantages: Through the coordination of a fixed frame, hopper, discharge ramp, discharge port, hoisting hopper, load-bearing frame, discharge plate, connecting shaft, connecting plate, discharge support rod, and arc-shaped support frame, a rectangular hinged door panel structure is used to seal the bottom of the hoisting hopper. This improves the sealing effect of the bottom of the hoisting hopper, preventing material spillage during hoisting due to jamming. During unloading, the discharge support rod is supported, which pulls the two discharge plates upward, causing them to flip at the connecting shaft, opening the bottom of the hoisting hopper. After unloading, the two discharge plates automatically return to a horizontal position under gravity, resealing the bottom of the hoisting hopper. Using a mechanical structure for unpowered, gravity-fed unloading eliminates the need for electrical control of the discharge port's opening and closing, reducing energy consumption and failure rate. Compared to traditional grid structures, it effectively improves unloading efficiency, thus contributing to increased enterprise production efficiency.

[0010] Through the coordination of the hopper, hoisting hopper, connecting plate, unloading support rod, chute, guide block, arc groove, limiting plate, vertical plate, and guide inclined plate, the unloading support rod is limited during hoisting to prevent accidental overturning of the unloading plate. During unloading, the hoisting hopper is guided to accurately fall into the hopper and supported by the limiting plate, thus preventing deviation or shaking during descent and improving the docking accuracy between the hoisting hopper and the hopper. The movement trajectory of the connecting plate is limited to prevent deviation or shaking during movement, ensuring smooth overturning of the unloading plate. The cooperation between these multiple structures helps to improve the overall stability and reliability of the unloading device. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In existing technologies, when hoisting tungsten concentrate raw materials, the discharge port of the hopper has poor sealing performance, which easily leads to material jamming. This causes material to spill during the hoisting process, resulting in pollution of the production environment and waste of raw materials. Furthermore, the hopper uses an electronic control method to control the opening and closing of the discharge port, which has high energy consumption and failure rate, affecting production efficiency.

[0019] In view of this, the present invention provides a gravity unloading hopper device. Through the cooperation of a fixed frame, hopper, discharge ramp, discharge port, hoisting hopper, load-bearing frame, discharge plate, connecting shaft, connecting plate, discharge support rod, and arc-shaped support frame, a rectangular hinged door panel structure is used to seal the bottom of the hoisting hopper, improving the sealing effect and preventing material spillage during hoisting due to jamming. During unloading, the discharge support rod is supported, which in turn pulls the two discharge plates upward, causing them to flip at the connecting shaft, thus opening the bottom of the hoisting hopper. After the unloading operation is completed, the two discharge plates automatically return to a horizontal position under gravity, resealing the bottom of the hoisting hopper. This achieves mechanical, unpowered, self-weight unloading, eliminating the need for electronic control of the discharge port's opening and closing, reducing energy consumption and failure rate. Compared with traditional grid structures, it effectively improves unloading efficiency and increases production efficiency.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Depend on Figure 1-5It is known that a gravity unloading hopper device includes a fixed frame 1, which supports and fixes a hopper 2 and is installed on the top of the loading end of the production equipment. The hopper 2 is fixedly connected to the upper part of the fixed frame 1. A discharge ramp 3 is fixedly connected to the inner wall of the hopper 2. A discharge port 4 is provided at the bottom of the discharge ramp 3. A hoisting hopper 5 is connected to the inner wall of the hopper 2. A load-bearing frame 6 is provided at the bottom of the inner wall of the hoisting hopper 5. Discharge plates 7 are movably connected to both sides of the hoisting hopper 5. The discharge plates 7 are connected to the hoisting hopper 5 and the load-bearing frame 6. The two discharge plates 7 are rotatably connected at their closest sides via a connecting shaft 8. Connecting plates 9 are rotatably connected to both ends of the connecting shaft 8. A discharge support rod 10 is fixedly connected to the top. A connecting rod 11 is fixedly connected to the side of the connecting plates 9 that are close to each other, located above the connecting shaft 8. The connecting rod 11 is used to improve the structural strength of the two connecting plates 9, ensure that the two connecting plates 9 will not deform during the discharge process, and ensure that the discharge plate 7 can be flipped smoothly. Arc-shaped support frames 12 are fixedly connected to both sides of the top of the fixed frame 1. The discharge support rod 10 is connected to the arc-shaped support frame 12. Rollers 13 are rotatably connected to both sides of the end of the discharge plate 7. The rollers 13 are used to improve the smoothness of the discharge plate 7 during the flipping process, reduce the frictional resistance between the discharge plate 7 and the bearing frame 6, and avoid jamming during the flipping process. The rollers 13 are connected to the bearing frame 6.

[0022] In the specific implementation process, it is worth noting that the fixing frame 1 is used to support and fix the hopper 2 and is installed on the top of the feeding end of the production equipment. Through the cooperation between the fixing frame 1, the hopper 2, the discharge ramp 3 and the discharge port 4, the material in the hopper 2 falls accurately into the feeding end of the production equipment through the discharge port 4 under the action of the discharge ramp 3 and gravity, avoiding material spillage. Through the cooperation between the hoisting hopper 5, the bearing frame 6, the unloading plate 7, the connecting shaft 8, the connecting plate 9 and the unloading support rod 10, the two unloading plates 7 are connected by the connecting shaft 8 to form a rectangular hinged door structure. When the two unloading plates 7 are in a horizontal position, the bottom of the two unloading plates 7 fits against the top of the bearing frame 6, sealing the bottom of the hoisting hopper 5, and... Under the influence of gravity, the hoisting hopper 5 is kept closed to maintain stability and prevent leakage of material particles during hoisting. When unloading is required, the unloading support rod 10 is moved upward, and under the drive of the connecting plate 9, the two unloading plates 7 are pulled at the connecting shaft 8, and then rotate around the connecting shaft 8 as the axis. The unloading plates 7 are adjusted from a horizontal posture to an inclined posture, and the bottom of the hoisting hopper 5 gradually opens, allowing the material to slide out of the hoisting hopper 5 under the influence of gravity. The connecting rod 11 is used to improve the structural strength of the two connecting plates 9, ensuring that the two connecting plates 9 will not deform during unloading and ensuring that the unloading plates 7 can be rotated smoothly. The roller 13 is used to improve the smoothness of the unloading plates 7 during the rotation process and reduce the friction between the unloading plates 7 and the supporting frame 6. To prevent resistance and jamming during the flipping process, the system utilizes the cooperation between the fixed frame 1, hopper 2, hoisting hopper 5, bearing frame 6, unloading plate 7, connecting shaft 8, connecting plate 9, unloading support rod 10, and arc-shaped support frame 12. After the hoisting hopper 5 is loaded with raw materials and hoisted above the hopper 2, it is moved downwards into the hopper 2. The unloading support rod 10 contacts the arc-shaped support frame 12, which then supports the unloading support rod 10, achieving automatic positioning for the hoisting docking and avoiding manual intervention. As the hoisting hopper 5 continues to descend, the unloading support rod 10 moves upwards relative to the hoisting hopper 5, causing the two unloading plates 7 to flip at the connecting shaft 8, gradually opening the bottom of the hoisting hopper 5. After completing the unloading operation, the hoisting hopper 5 moves upwards. Upon movement, under the influence of gravity, the two unloading plates 7 automatically return to a horizontal position, and the unloading support rod 10 separates from the arc-shaped support frame 12. The unloading plates 7 re-close the bottom of the hoisting hopper 5, facilitating the next hoisting operation. This achieves unpowered, self-weight unloading, reducing energy consumption and maintenance costs. Through the cooperation between the fixed frame 1, hopper 2, unloading ramp 3, unloading port 4, hoisting hopper 5, load-bearing frame 6, unloading plate 7, connecting shaft 8, connecting plate 9, unloading support rod 10, and arc-shaped support frame 12, a rectangular hinged door panel structure is used to close the bottom of the hoisting hopper 5, improving the sealing effect of the bottom of the hoisting hopper 5 and preventing material spillage during hoisting due to jamming. During unloading, the unloading support rod 10 is supported.This, in turn, pulls the two unloading plates 7 upwards, causing them to flip at the connecting shaft 8, opening the bottom of the hoisting hopper 5. After unloading, under gravity, the two unloading plates 7 automatically return to a horizontal position, re-closing the bottom of the hoisting hopper 5. This achieves mechanical, unpowered, gravity-based unloading, eliminating the need for electronic control of the unloading port's opening and closing, reducing energy consumption and failure rate. Compared to traditional grid structures, this effectively improves unloading efficiency and increases production efficiency.

[0023] Furthermore, both sides of the inner wall of the hoisting hopper 5 are provided with sliding grooves 14, and a guide block 15 is fixedly connected to the side of the connecting plate 9 away from the connecting rod 11. The guide block 15 is slidably connected to the sliding groove 14. Both sides of the top of the hoisting hopper 5 are provided with arc-shaped grooves 16. The unloading support rod 10 is connected to the arc-shaped grooves 16. Both sides of the outer wall of the hoisting hopper 5 are fixedly connected with limit plates 17 at equal intervals. The limit plates 17 are connected to the hopper 2. The top of the hopper 2 is provided with vertical plates 18 at equal intervals. The top of the vertical plates 18 is provided with guide inclined plates 19. The hoisting hopper 5 is connected to the vertical plates 18 and the guide inclined plates 19 respectively.

[0024] In the specific implementation process, it is worth noting that, through the cooperation between the hoisting hopper 5, the connecting plate 9, the chute 14, and the guide block 15, when the unloading support rod 10 pulls the connecting plate 9 to move, the guide block 15 slides in the chute 14, limiting the movement trajectory of the connecting plate 9 and ensuring that the connecting plate 9 can move stably in a straight line along the chute 14. This prevents the connecting plate 9 from shifting or shaking during movement, ensuring that the unloading plate 7 can be smoothly flipped. Through the cooperation between the hoisting hopper 5, the unloading support rod 10, and the arc-shaped groove 16, when the unloading plate 7 is in the position of... When the hoisting hopper 5 is in a closed position, the unloading support rod 10 forms support and limit within the arc-shaped groove 16, preventing the unloading plate 7 from accidentally overturning during hoisting and ensuring the sealing of the hoisting hopper 5. Through the cooperation between the hopper 2, the hoisting hopper 5, and the limiting plate 17, when the hoisting hopper 5 is unloading, the limiting plate 17 is locked at the top of the hopper 2 to limit its position, so that the hoisting hopper 5 forms support at the top of the hopper 2. Through the cooperation between the hopper 2, the hoisting hopper 5, the vertical plate 18, and the guide inclined plate 19, when the hoisting hopper 5 falls from above the hopper 2, it is positioned within the material storage area. The guide ramp 19 and vertical plate 18 at the top of bin 2 guide the hoisting hopper 5, ensuring that the hoisting hopper 5 falls accurately into the interior of bin 2, preventing deviation or shaking during descent, improving the docking accuracy between the hoisting hopper 5 and bin 2, and ensuring smooth unloading. Through the cooperation between bin 2, hoisting hopper 5, connecting plate 9, unloading support rod 10, chute 14, guide block 15, arc groove 16, limiting plate 17, vertical plate 18, and guide ramp 19, the arc groove 16 limits the unloading support rod 10 during hoisting, preventing the unloading plate 7 from being moved during hoisting. In the event of an accidental overturning during the unloading process, the hoisting hopper 5 is guided by the vertical plate 18 and the guide inclined plate 19, ensuring that the hoisting hopper 5 can accurately fall into the interior of the hopper 2. It is supported by the limiting plate 17 to prevent deviation or shaking during the descent, thereby improving the docking accuracy between the hoisting hopper 5 and the hopper 2. By limiting the movement trajectory of the connecting plate 9, deviation or shaking during the movement of the connecting plate 9 is prevented, ensuring that the unloading plate 7 can be smoothly overturned. Through the cooperation between multiple structures, the overall stability and reliability of the unloading device are improved.

[0025] Furthermore, lifting lugs 20 are provided at equal intervals on both sides of the top of the hoisting hopper 5, and fixing holes 21 are provided inside the lifting lugs 20;

[0026] In the specific implementation process, it is worth noting that through the cooperation between the hoisting hopper 5, the lifting lug 20 and the fixing hole 21, by setting the lifting lug 20 on the top of the hoisting hopper 5 and opening the fixing hole 21 inside the lifting lug 20, it is convenient to use external hoisting equipment to hoist the hoisting hopper 5, realize fast and stable hoisting operation, and improve the practicality and convenience of the unloading device.

[0027] Furthermore, polyurethane wear-resistant sleeves 22 are fitted onto the outer walls of both ends of the unloading support rod 10. The polyurethane wear-resistant sleeves 22 are used to improve the wear resistance of the unloading support rod 10. The polyurethane wear-resistant sleeves 22 are respectively connected to the arc-shaped support frame 12 and the arc-shaped groove 16.

[0028] In the specific implementation process, it is worth noting that the polyurethane wear-resistant sleeve 22 is used to improve the wear resistance of the unloading support rod 10, reduce the frictional resistance of the unloading support rod 10 in the arc support frame 12 and arc groove 16, and avoid wear during long-term use.

[0029] Furthermore, a rubber pad 23 is fixedly connected to the bottom of the limiting plate 17. The rubber pad 23 is used to improve the stability of the limiting plate 17 at the top of the hopper 2 and to act as a buffer when the limiting plate 17 comes into contact with the hopper 2. The rubber pad 23 is connected to the hopper 2 in cooperation.

[0030] In the specific implementation process, it is worth noting that the rubber pad 23 is used to improve the stability of the limiting plate 17 at the top of the hopper 2 and to act as a buffer when the limiting plate 17 comes into contact with the hopper 2, so as to avoid the limiting plate 17 causing a hard impact on the hopper 2, protect the surface of the hopper 2 from damage, and improve the accuracy and reliability of the unloading operation.
