Description

Technical Field

[0001] This utility model belongs to the field of ore processing, specifically, it relates to an ore crushing and screening device. Background Technology

[0002] Ore refers to a natural mineral aggregate containing economically valuable minerals (or components) extracted from the Earth's crust. Its core characteristic is its value for mining and processing—through physical and chemical methods, metals (such as iron, copper, aluminum, and gold), non-metals (such as limestone, gypsum, and quartz sand), or energy minerals (such as coal and oil shale) can be extracted. It is a fundamental raw material for industrial production. In the ore processing industry, crushing and screening are crucial steps. However, existing ore crushing and screening devices cannot effectively screen ore by size, and the screening plates are prone to clogging, causing ore to accumulate and resulting in low screening efficiency.

[0003] Chinese patent publication number CN220345943U discloses an ore crushing and screening device. This device can screen ores of different sizes through a screening structure and a vibration structure. During screening, the screening plate vibrates to prevent ore from clogging the screening plate, allowing the ore to spread on the screening plate and be screened quickly, thus improving screening efficiency. However, after the device continuously crushes the ore with crushing rollers, the crushed ore tends to accumulate on the screening structure because the crushing rollers and the screening mechanism are close together, which can easily lead to uneven screening. At the same time, the dust generated after crushing is large and can easily spread into the equipment and the surrounding environment, affecting the operation of the equipment and the surrounding workers. In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please see Figure 1-11 As shown, this embodiment provides an ore crushing and screening device, including a base 1, a crushing mechanism 2 and a auger conveyor 8, which are fixedly installed on the base 1 relative to the crushing mechanism 2. The inlet end of the auger conveyor 8 and the discharge end of the crushing mechanism 2 are connected through a connecting bucket 12. The base 1 is provided with a spraying assembly 7 for spraying water mist into the connecting bucket 12. The discharge end of the auger conveyor 8 is connected to a discharge pipe 3. The base 1 is provided with a screening assembly 9 relative to the discharge end of the discharge pipe 3.

[0020] Specifically, after the ore is crushed by the crushing mechanism 2, it falls into the auger conveying mechanism 8 through the connecting bucket 12. The spraying component 7 sprays water mist into the connecting bucket 12 to suppress dust. The auger conveying mechanism 8 transports the ore to the discharge pipe 3, and finally the screening component 9 completes the grading. The integrated design realizes continuous operation of crushing, conveying and screening, improving production efficiency. The connecting bucket 12 serves as a transition area and works with the spraying component 7 to effectively control the spread of dust.

[0021] It should be noted that in this embodiment, the structure and working principle of the crushing mechanism 2 and the auger conveying mechanism 8 are existing technologies and will not be described here. Each device is controlled by an external control device.

[0022] In this embodiment, as Figures 1 to 11 As shown, the spray assembly 7 includes a water pump 71, which is fixedly installed on the base 1. A water tank 72, which is connected to the water pump 71, is fixedly installed on the base 1. The water pump 71 has a discharge end connected to a conveying pipe 73 and a spray pipe 75, which is located inside the connecting hopper 12. A drain pipe 74 connects the spray pipe 75 and the conveying pipe 73. Specifically, the water pump 71 draws water from the water tank 72 and delivers the water to the spray pipe 75 through the conveying pipe 73 and the drain pipe 74. The nozzle atomizes the water and sprays it onto the surface of the ore inside the connecting hopper 12. The atomized water combines with the dust particles to increase their weight, suppressing dust from flying, which is environmentally friendly and efficient.

[0023] In this embodiment, as Figures 3 to 8 As shown, a flushing pipe 14 is connected to the conveying pipe 73. The other end of the flushing pipe 14 is connected to the conveying channel inside the auger conveyor 8. A mounting bracket 13 for installing the flushing pipe 14 and the water inlet pipe is fixedly installed on the auger conveyor 8. Valves 15 are provided on both the flushing pipe 14 and the drain pipe 74. Specifically, the conveying pipe 73 supplies water to the inside of the auger conveyor 8 through the flushing pipe 14. The valve 15 controls the direction of water flow, realizing the switching between dust suppression and equipment cleaning. The flushing function can remove residual ore inside the auger conveyor 8 and prevent material accumulation from affecting the conveying efficiency.

[0024] In this embodiment, as Figure 5 and Figure 6 As shown, an installation pipe 11 is rotatably mounted on the connecting bucket 12. One end of the installation pipe 11 is connected to the spray pipe 75, and the other end is connected to the drainage pipe 74 through a rotary joint 10. The connecting bucket 12 is equipped with a drive assembly 6 for driving the installation pipe 11 to rotate. A baffle 17 is fixedly installed in the connecting bucket 12 relative to the spray pipe 75 and is inclined downward. The drive assembly 6 includes a motor 61 fixedly mounted on the connecting bucket 12, a drive gear 62 sleeved and fixedly mounted on the drive shaft of the motor 61, and a driven gear 63 sleeved and fixedly mounted on the installation pipe 11. The drive gear 62 and the driven gear 63 mesh.

[0025] In this embodiment, as Figures 4 to 11As shown, the diameter of the driving gear 62 is smaller than the diameter of the driven gear 63. A vibration assembly 16 is provided on the connecting bucket 12. The vibration assembly 16 includes a first support plate 164, which is fixedly mounted on the connecting bucket 12. A rotating shaft 163 is rotatably mounted on the first support plate 164. A second bevel gear 162 is sleeved and fixedly mounted on the first end of the rotating shaft 163. A first bevel gear 161, meshing with the second bevel gear 162, is sleeved and fixedly mounted on the drive shaft of the motor 61. A cam 165 is sleeved and fixedly mounted on the second end of the rotating shaft 163. Multiple sets of second support plates 168 are fixedly mounted on the connecting bucket 12 at intervals. Each set of second support plates 168 is rotatably equipped with a striking rod 167. A tension spring 169 connects the striking rod 167 to the connecting bucket 12. One end of the striking rod 167 is attached to the connecting bucket 12, and the other end is fixedly mounted with an abutment plate 166. The abutment plate 166 abuts against the cam 165. Specifically, when the motor 61 is energized, the motor 61 drives the shaft to rotate at high speed. The first bevel gear 161, which is sleeved and fixed on the drive shaft, rotates synchronously. The rotation of the first bevel gear 161 drives the second bevel gear 162 to rotate, which in turn causes the rotating shaft 163, which is fixedly mounted at the center of the second bevel gear 162, to start rotating. The cam 165, which is sleeved and fixedly mounted on the second end of the rotating shaft 163, performs a circular motion as the rotating shaft 163 rotates. During the rotation, the contour curve of the cam 165 changes continuously, and it periodically contacts and presses against the abutment plate 166. When the cam 165 and the abutment plate 166... When contact and compression occur, the contact plate 166 is subjected to an external force applied by the cam 165, causing the striking rod 167, which is fixedly connected to it, to rotate around the rotation point on the second support plate 168. At this time, the end of the striking rod 167 that is in contact with the connecting bucket 12 gradually moves away from the connecting bucket 12, while the tension spring 169 is stretched, storing elastic potential energy. When the cam 165 continues to rotate and disengages from the contact plate 166, the tension spring 169 releases its elastic potential energy, pulling the striking rod 167 to quickly return to its original position. The end of the striking rod 167 that is in contact with the connecting bucket 12 quickly impacts the outer wall of the connecting bucket 12. With the motor 61 continuously running, the cam 165 rotates continuously, repeating the above process, causing multiple sets of striking rods 167 to alternately strike the outer wall of the connecting bucket 12 at a high frequency. During the process of crushing the ore and sending it through the connecting hopper 12 into the auger conveyor 8, some of the crushed ore may adhere to the inner wall of the connecting hopper 12 due to its own stickiness, moisture, or particle shape. Over time, this can easily cause blockage in the connecting hopper 12, affecting material conveying efficiency. The impact of the vibrating component 16 continuously applies impact force to the outer wall of the connecting hopper 12, causing the connecting hopper 12 to vibrate slightly. This vibration is transmitted to the inside of the connecting hopper 12, breaking the adhesion between the material and the inner wall of the connecting hopper 12, preventing the material from accumulating and sticking on the inner wall of the connecting hopper 12, and ensuring that the material can smoothly pass through the connecting hopper 12 into the auger conveyor 8, maintaining the continuous and stable operation of the entire ore crushing and screening device. This is achieved through the high-frequency impact of multiple sets of striking rods 167.The material inside the connecting hopper 12 is subjected to vibration during its descent, improving its flow. Material particles that might have clumped together are broken up by the vibration, increasing their fluidity and making it easier for them to enter the inlet of the auger conveyor mechanism 8 from the connecting hopper 12. This reduces the material's residence time in the connecting hopper 12, significantly improving the smoothness of material transport from the crushing mechanism 2 to the auger conveyor mechanism 8, and contributing to increased overall equipment efficiency.

[0026] In this embodiment, as Figures 1 to 8 As shown, the screening assembly 9 includes a fixed frame 91, which is fixedly installed on the base 1. A vibrating frame 93 is fixedly installed on the fixed frame 91 at an angle by multiple sets of spring mechanisms 92. The multiple sets of spring mechanisms 92 are arranged opposite to each other on both sides of the vibrating frame 93. An eccentric wheel vibration mechanism 95 for driving the vibration of the vibrating frame 93 is provided on the fixed frame 91. A vibrating screen 94 is fixedly installed inside the vibrating frame 93. A funnel-shaped discharge port 5 is defined at the bottom of the vibrating frame 93. A collection trough 4 is fixedly installed on the base 1 opposite to the discharge port 5.

[0027] Working principle: The ore to be processed enters the crushing mechanism 2 for crushing. The crushed ore is discharged from the discharge end of the crushing mechanism 2 and transitions to the inlet end of the auger conveyor mechanism 8 via the connecting bucket 12. At this time, the water pump 71, controlled by an external control device, draws water from the water tank 72 and delivers it through the conveying pipe 73 and the drainage pipe 74 (via the rotary joint 10) to the installation pipe 11 inside the connecting bucket 12. The spray pipe 75 atomizes the water and sprays it out. At the same time, the drive assembly 6 (motor 61 drives the drive gear 62 to mesh with the driven gear 63) drives the installation pipe 11 to rotate, causing the spray pipe 75 to rotate inside the connecting bucket 12, uniformly spraying water mist onto the crushed ore. The spray pipe is connected to multiple atomizing nozzles to fully wet the surface of the ore, suppressing dust generation and diffusion. Motor 61 drives the shaft to rotate at high speed, causing the first bevel gear 161, which is sleeved and fixed on the drive shaft, to rotate synchronously. The rotation of the first bevel gear 161 drives the second bevel gear 162 to rotate, which in turn causes the rotating shaft 163, fixedly installed at the center of the second bevel gear 162, to begin rotating. A cam 165, sleeved and fixedly installed at the second end of the rotating shaft 163, performs circular motion as the rotating shaft 163 rotates. During rotation, the profile curve of the cam 165 continuously changes, periodically contacting and pressing against the contact plate 166. When the cam 165... When the cam 165 contacts and presses against the contact plate 166, the contact plate 166 is subjected to an external force applied by the cam 165, which drives the striking rod 167, which is fixedly connected to it, to rotate around the rotation point on the second support plate 168. At this time, the end of the striking rod 167 that is in contact with the connecting bucket 12 gradually moves away from the connecting bucket 12, and at the same time, the tension spring 169 is stretched and stores elastic potential energy. When the cam 165 continues to rotate and disengages from the contact plate 166, the tension spring 169 releases its elastic potential energy, pulling the striking rod 167 to quickly return to its original position. The end of the striking rod 167 that is in contact with the connecting bucket 12 quickly strikes the outer wall of the connecting bucket 12. Under the continuous operation of the motor 61, the cam 165 does not... The rotation is interrupted, and the above process is repeated, so that multiple sets of striking rods 167 strike the outer wall of the connecting bucket 12 at high frequency, causing the material to adhere to the connecting bucket 12. The ore treated with water mist is transported in an orderly manner to the discharge pipe 3 through the auger conveyor mechanism 8, and finally discharged from the discharge pipe 3 to the vibrating screen 94 of the screening component 9. The eccentric wheel vibration mechanism 95 drives the vibrating frame 93 to vibrate (the spring mechanism 92 assists in the vibration). Because the vibrating frame 93 is inclined, the ore on the vibrating screen 94 moves along the inclined direction under the action of vibration to avoid accumulation. The smaller particle size ore falls into the bottom of the vibrating frame 93 through the vibrating screen 94 and is discharged to the collection tank 4 through the funnel-shaped discharge port 5.Larger ore particles move along the surface of the vibrating screen 94 and are discharged along the bottom of the vibrating frame 93, completing the grading and screening. Next, if cleaning the auger conveyor mechanism 8 is required, valve 15 can be switched to allow water to flow into the conveying channel through the flushing pipe 14 to remove residual ore. The overall structure and operation are simple, enabling water spraying to absorb the dust after crushing, reducing dust dispersion, and preventing crushed ore from falling directly onto the vibrating screen 94. The auger conveyor mechanism 8 increases the conveying distance, improving the overall screening uniformity.
