Description

Technical Field

[0001] This utility model relates to the field of mineral processing feeding technology, and in particular to a feeding machine for gold ore beneficiation and processing. Background Technology

[0002] Gold deposits are naturally occurring gold-bearing deposits within the Earth's crust that have mining value. Gold deposits primarily exist in the form of gold and are generally classified into two main categories: primary gold deposits and placer gold deposits. In primary gold deposits, gold is often embedded in gangue minerals such as quartz and calcite in a free state or in association with sulfides, and is mainly found in igneous or metamorphic rocks. Placer gold deposits, on the other hand, are secondary deposits formed when primary gold has been weathered and eroded, then transported and deposited by water in rivers, lakes, or beaches.

[0003] In gold ore processing, feeding and conveying are typically achieved using equipment such as screw conveyors. However, existing ore feeders, lacking crushing and screening mechanisms, are prone to clogging and wear on the screw conveyor when larger pieces of gold ore are being transported. This not only affects the continuity and stability of feeding but also leads to significant load fluctuations in subsequent crushing and grinding equipment, thereby reducing beneficiation efficiency and increasing energy consumption and maintenance costs. Consequently, they fail to meet the requirements of continuous, uniform, and controllable material feeding in different process stages of gold ore beneficiation equipment. Therefore, their application has certain limitations.

[0004] Based on this, we propose a feeding machine for gold ore beneficiation and processing to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a feeding machine for gold ore beneficiation and processing, which can solve the problems of existing ore feeding machines, such as the lack of crushing and screening mechanisms, which leads to material blockage and wear of the spiral conveyor, large load fluctuations of subsequent crushing and grinding equipment, low beneficiation efficiency, and increased energy consumption and operation and maintenance costs, making it difficult to achieve continuous, uniform and controllable material feeding.

[0007] To solve the above technical problems, this utility model provides a feeding machine for gold ore beneficiation and processing, which adopts the following technical solution: it includes a feeding bracket, and a ore conveying component is installed inside the feeding bracket. An ore screening component is also provided at the top of one end of the ore conveying component. The ore conveying component includes a spiral conveying cylinder. The feed port of the spiral conveying cylinder is connected to a feed hopper. A conveying motor is also provided at the top of the end of the spiral conveying cylinder near the feed hopper.

[0008] The mineral screening component includes a mineral crushing component, and a mineral screening component is provided at the bottom of the mineral crushing component.

[0009] Optionally, the mineral screening component includes a first housing, a first pulley connected to the middle of one side of the first housing via a bearing, a motor drive box located at the bottom of the first housing near the first pulley, the motor drive box being connected to the first pulley via a transmission belt, and a screening screen plate being inclinedly arranged inside the first housing.

[0010] Optionally, the output end of the first pulley is connected to a vibrating turntable, which is located on one side of the inner wall of the first housing. Several sets of circumferentially arrayed cams are distributed on the outer side of the vibrating turntable, and the cams are in rolling contact with the edge of the screening screen plate.

[0011] Optionally, the top of the first box has an inner opening, and the bottom of the first box is connected to a first inner plate around the perimeter. The first inner plate is plugged into the feed inlet of the feed hopper. Two sets of guide slots are opened on both sides of the first box. A discharge plate is also inclinedly installed on the top of the side of the first box away from the guide slots. The installation angle of the discharge plate matches the screening screen plate.

[0012] Optionally, the ore crushing component includes a second housing, inside which two sets of crushing shafts are connected via bearings. A transmission connection box is installed on one side of the exterior of the second housing, and the transmission connection box is connected to the two sets of crushing shafts via transmission. A second pulley is provided at one end of the transmission connection box, and the second pulley is connected to the first pulley via a transmission belt. A second inner plate is also provided at the bottom of the second housing, and the second inner plate is inserted into the inner opening.

[0013] Optionally, two sets of guide blocks are installed on both sides of the screening screen plate. The guide blocks are matched with the guide groove structure and are in sliding fit with the guide groove. Compression springs are also connected to both sides of the guide blocks.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The gold ore feeding machine designed in this scheme can effectively improve the pre-processing efficiency of gold ore and achieve efficient feeding of gold ore by setting up a ore conveying component and an ore screening component inside the feeding bracket. The ore screening component includes an ore crushing component and an ore screening component. When the motor drive box is powered on, it can drive two sets of crushing shafts to rotate inside the second box. The rotating two sets of crushing shafts can crush the gold ore, which can reduce the particle size of the gold ore to be processed. This prevents the spiral conveyor from causing internal blockage or severe wear due to the large particle size of the gold ore when feeding and conveying it, thus achieving stable conveying of gold ore.

[0016] 2. The gold ore feeding machine designed in this scheme incorporates a ore screening component installed at the bottom of the ore crushing unit. This screening component mainly consists of a first box, a first pulley, and a screening screen. A powered motor drives the vibrating turntable and cam to rotate. The cam contacts the frame of the screening screen, causing it to vibrate at a high frequency inside the first box. When the crushed gold ore falls from the second box onto the surface of the screening screen, it filters and screens the ore, achieving particle size classification. Ore smaller than the mesh size enters the feed hopper and is conveyed to different process sections of the mineral processing equipment via a screw conveyor and a conveyor motor. Larger ore particles are discharged along the screening screen and discharge plate. This effectively prevents blockages or severe wear of the screw conveyor due to the large particle size of the gold ore during use, thus improving the practicality of the equipment in the field of mineral processing feeding technology.

[0027] 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.

[0028] Example: Refer to Figures 1 to 8This utility model provides an embodiment of a gold ore beneficiation and processing feeding machine, including a feeding bracket 1. The feeding bracket 1 is characterized by having an internal ore conveying assembly 2, with an ore screening assembly 3 located at one top end. The ore conveying assembly 2 includes a spiral conveyor 4, with a feed hopper 5 connected to its inlet port. A conveying motor 6 is located at the top end of the spiral conveyor 4 near the feed hopper 5. The ore screening assembly 3 includes an ore crushing component 7, with a ore screening component 8 located at its bottom. This gold ore feeding machine, through the coordinated use of a second housing 19, a crushing shaft 20, a transmission connection box 21, and a second pulley 22, can process ore fed into the second housing 19. The crushing process of the gold ore in the ore processing can reduce the particle size of the gold ore and prevent the spiral conveyor 4 from becoming clogged or severely worn due to the large particle size of the gold ore during feeding. The ore screening component 8 includes a first box 9. A first pulley 10 is connected to the middle of one side of the first box 9 via a bearing. A motor drive box 11 is provided at the bottom of the first box 9 near the first pulley 10. The motor drive box 11 is connected to the first pulley 10 via a transmission belt. A screening screen 12 is also inclinedly installed inside the first box 9. The gold ore falling from the ore crushing component 7 can be screened and filtered through the inclined screening screen 12 inside the first box 9.

[0029] The output end of the first pulley 10 is connected to a vibrating turntable 13, which is located on one side of the inner wall of the first housing 9. Several sets of circumferentially arrayed cams 14 are distributed on the outer side of the vibrating turntable 13. The cams 14 and the frame of the screening screen plate 12 are in rolling contact. Through this rolling contact design, when the motor drive box 11 is powered on, it can drive the vibrating turntable 13 and cams 14, which are mounted on one side of the inner wall of the first housing 9, to rotate. The rotating cams 14 can move the screening screen plate 12, which is inclined and installed inside the first housing 9, up and down. The top of the first housing 9 has an inset opening 15. The bottom of the body 9 is connected to the first inner plate 16. The first inner plate 16 and the feed inlet of the feed hopper 5 are connected by a plug-in fit. Two sets of guide slots 17 are opened on both sides of the first box body 9. The top of the side of the first box body 9 away from the guide slots 17 is also inclinedly provided with a discharge plate 18. The installation angle of the discharge plate 18 matches the screening screen plate 12. Through the structural design that the installation angle of the discharge plate 18 matches the screening screen plate 12, when the particle size of the crushed gold ore is larger than the mesh of the screening screen plate 12, the screened gold ore can be discharged outward along the inclination of the screening screen plate 12 and the discharge plate 18, which can prevent the gold ore with a larger particle size from entering the ore conveying component 2.

[0030] The ore crushing component 7 includes a second housing 19. Two sets of crushing shafts 20 are connected inside the second housing 19 via bearings. A transmission connection box 21 is installed on one side of the outer side of the second housing 19, providing a transmission connection between the transmission connection box 21 and the two sets of crushing shafts 20. A second pulley 22 is provided at one end of the transmission connection box 21, and the second pulley 22 is connected to the first pulley 10 via a transmission belt. A second inner plate 23 is also provided at the bottom of the second housing 19, and the second inner plate 23 is inserted into the inner opening 15. When the motor drive box 11 installed on one side of the bottom of the first housing 9 is powered on, the crushing shafts 20 installed inside the second housing 19 are connected to the first pulley 10 via a transmission belt, and the second pulley 22 is connected to the first pulley 10 via a transmission belt. The two sets of crushing shafts 20 are connected by a transmission mechanism. The motor drive box 11, which is powered on, can drive the two sets of crushing shafts 20 to rotate inside the second box 19. The two sets of crushing shafts 20 can crush the gold ore fed into the second box 19, thereby reducing the particle size of the gold ore. Two sets of guide blocks 24 are installed on both sides of the screening screen plate 12. The guide blocks 24 and the guide slots 17 are structurally matched and have a sliding fit. Compression springs 25 are also connected to both sides of the guide blocks 24. By adding two sets of guide blocks 24 and compression springs 25 to both sides of the screening screen plate 12, and by using the elastic effect of the compression springs 25, the screening screen plate 12, which is installed at a predetermined tilt angle, can be stably and elastically limited inside the first box 9.

[0031] Working Principle: The gold ore feeding machine designed in this scheme mainly consists of a feeding bracket 1, a ore conveying assembly 2, and an ore screening assembly 3. The ore screening assembly 3 includes an ore crushing component 7 and an ore screening component 8. The ore crushing component 7 is used in conjunction with the second housing 19, the crushing shaft 20, the transmission connecting box 21, and the second pulley 22. When the motor drive box 11 installed on one side of the bottom of the first housing 9 is powered on, the motor drive box 11 is connected to the first pulley 10 via a transmission belt. The transmission connection is such that the second pulley 22 is connected to the first pulley 10 via a transmission belt. The motor drive box 11, which is powered on, can drive the two sets of crushing shafts 20 to rotate inside the second box 19. The two sets of crushing shafts 20 can crush the gold ore fed into the second box 19, which can reduce the particle size of the gold ore and prevent the spiral conveyor 4 from causing internal blockage or severe wear due to the large particle size of the gold ore when feeding and conveying it.

[0032] The gold ore feeding machine designed in this scheme uses a ore screening component 8 installed at the bottom of the ore crushing component 7. The ore screening component 8 is mainly composed of a first housing 9, a first pulley 10, and a screening screen 12. The first housing 9 works in conjunction with the screening screen 12, the vibrating turntable 13, and the cam 14. When the motor drive box 11 is powered on, it can drive the two sets of crushing shafts 20 to rotate inside the second housing 19, and at the same time drive the vibrating turntable 13 and the cam 14 installed on one side of the inner wall of the first housing 9 to rotate. Because the cam 14 and The edges of the screening screen plate 12 are in rolling contact. The rotating cam 14 can move the screening screen plate 12, which is inclined and installed inside the first box 9, up and down. The screen plate 12, which is moved, can undergo high-frequency elastic vibration inside the first box 9 through the structural cooperation between the guide slot 17, the guide block 24, and the compression spring 25. When the crushed gold ore falls from the second box 19 onto the surface of the screening screen plate 12, the high-frequency elastically vibrating screening screen plate 12 can screen and filter the crushed gold ore.

[0033] The gold ore feeding machine designed in this scheme allows the crushed gold ore particles smaller than the mesh size of the screening screen 12 to pass through the screen 12 and enter the feed hopper 5. The feed hopper 5, through the cooperation of the screw conveyor 4 and the conveying motor 6, can transport the gold ore to different process stages of the gold ore beneficiation equipment. When the crushed gold ore particles are larger than the mesh size of the screening screen 12, the screened gold ore can be discharged outward along the inclination of the screening screen 12 and the discharge plate 18. This prevents larger gold ore particles from entering the ore conveying assembly 2 and effectively prevents the screw conveyor 4 from becoming clogged or severely worn due to the larger gold ore particles during use.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
