Description

Technical Field

[0001] This invention belongs to the field of sorting and conveying technology, specifically, it relates to a quartz sand stratified conveying device and method based on visual inspection. Background Technology

[0002] Quartz sand is an important industrial mineral raw material, widely used in glass manufacturing, metallurgy, chemical industry, new building materials, and many other fields. Industrial quartz sand requires extremely high purity and particle uniformity. Large particles, agglomerated impurities, and hardened gravel lumps in the raw material can severely affect the quality of the finished quartz sand. Therefore, screening for impurity removal and stratified conveying are core processes in quartz sand production and processing. Currently, the industry commonly uses ore color sorting equipment for visual screening and impurity removal of quartz sand raw materials. Visual recognition technology distinguishes qualified quartz sand from large-particle waste materials, which are then diverted and conveyed by a conveying mechanism.

[0003] In existing technologies, after the quartz sand color sorting and screening, the qualified finished product and large particle waste are mostly conveyed directly to the corresponding conveyor belt through a fixed feed chute. However, in actual production conditions, it has been found that large particle waste has a large self-weight and strong falling kinetic energy. During the synchronous falling of multiple particles, they are very prone to collision and interference. After the collision, the large particles will splash and scatter in all directions, which will not only cause quartz sand waste to be scattered and overflow, but also lead to the loss of production raw materials and a dirty and messy workshop environment.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A quartz sand stratified conveying device based on visual inspection includes an ore color sorter containing a visual inspection system, wherein the ore color sorter is provided with a finished material conveyor belt body and a waste material conveyor belt body at the material discharge position. The waste conveyor belt body is equipped with a second guide hopper, and a telescopic chute is installed at the bottom of the second guide hopper. A push plate is installed on the waste conveyor belt body. The push plate is used to drive the telescopic chute to swing back and forth, thereby changing the feeding position and preventing waste from falling and colliding with each other, which would cause waste to splash. The waste conveyor belt body is also equipped with a guide rail. The guide rail is arched. The bottom of the telescopic chute is slidably set in the guide rail, and the highest point of the guide rail is located at the center of the waste conveyor belt body. When it moves to slide on both sides of the guide rail, the vertical distance between the telescopic chute and the waste conveyor belt body is reduced, which reduces the kinetic energy of the material hitting the conveyor belt and causing splashing. Its outlet faces the center of the waste conveyor belt body, which reduces the situation of material scattering to the outside. A horizontal plate is vertically slidably installed on the waste conveyor belt body, and the horizontal plate is slidably connected to the bottom of the telescopic chute. When the telescopic chute moves to both sides of the guide rail, it drives the adjusting plug located inside the second guide bucket to move down, thereby reducing the material feeding speed and reducing the occurrence of raw material spillage.

[0006] In a preferred embodiment of the present invention, a positioning frame is installed at the bottom of the ore color sorter, and several pairs of reinforcing ribs are also installed on the upper part of the positioning frame. An adjusting rod is also installed at the bottom of the positioning frame by bolts. A pad is installed at the bottom of the adjusting rod, and the pad is in the shape of a boss. An indicator light is installed on the ore color sorter, and a controller is also installed on the side wall of the ore color sorter.

[0007] In a preferred embodiment of the present invention, the ore color sorter has a feeding port on the top, and an observation window is also installed on the outer shell of the color sorting position of the ore color sorter.

[0008] In a preferred embodiment of the present invention, a support frame is installed on the finished material conveyor belt body. The support frame is L-shaped, and a first guide bucket is installed on the top of the support frame. The first guide bucket corresponds to the finished material discharge position of the ore color sorter, and the second guide bucket corresponds to the waste material discharge position of the ore color sorter. A bracket for support is also installed on the side wall of the second guide bucket.

[0009] In a preferred embodiment of the present invention, a collar is installed on the top of the push plate, the collar is sleeved on the outer wall of the telescopic chute, a reciprocating electric push rod is provided on the outer wall of the collar, the outer shell of the reciprocating electric push rod is provided with a boss for support, and the reciprocating electric push rod is used to drive the push plate to swing back and forth.

[0010] In a preferred embodiment of the present invention, a connecting frame is installed at the bottom of the telescopic chute, a slider is installed on the side wall of the connecting frame, a sliding rod is installed at the end of the slider, and a strip groove is provided on the push plate, the strip groove being slidably connected to the sliding rod.

[0011] In a preferred embodiment of the present invention, the guide rail is provided with fixed seats at both ends, the fixed seats are installed on the outer frame of the waste conveyor belt body at both ends, and the guide rail is provided with a sliding groove, which is slidably connected to the slider.

[0012] In a preferred embodiment of the present invention, a slot is formed in the horizontal plate, and a sliding rod is slidably installed inside the slot. Slide plates are installed at both ends of the horizontal plate, and a limiting rod is movably installed through the slide plate. The limiting rod is in a vertical state, and the bottom of the limiting rod is installed on the outer frame of the waste conveyor belt. A limiting plate is installed at the top of the limiting rod, and the cross-sectional area of ​​the limiting plate is larger than the cross-sectional area of ​​the limiting rod. The limiting plate is used to prevent the slide plate from separating from the limiting rod.

[0013] In a preferred embodiment of the present invention, a top plate is installed on the horizontal plate, the top plate is movably connected to the second guide hopper, a guide block is installed at the center of the top plate, and the top of the guide block has an inclined surface. An adjusting plug is installed at the bottom of the guide block, the adjusting plug is aligned with the telescopic chute, and the adjusting plug is conical.

[0014] A method for layered conveying of quartz sand based on visual inspection, comprising the following steps: Step 1: Start the entire machine through the controller on the side wall of the ore color sorter. The indicator lights will light up simultaneously and show the standby working status of the equipment. The staff can check the internal working condition of the equipment through the observation window. After the debugging is completed, put the quartz sand raw material to be sorted into the feed port at the top of the ore color sorter. Step 2: The quartz sand raw material is fed into the ore color sorter and falls evenly and horizontally. The high-speed, high-definition vision detection module built into the equipment scans the material flow frame by frame at a high frame rate, and collects data on the particle size, shape, and grayscale color difference of the quartz sand in real time. It accurately identifies large particles with excessive particle size, agglomerated impurities, hard lumps of sand and gravel, and other large particle defects, and transmits the collected data to the controller in real time. The controller, based on the built-in high-precision particle identification algorithm, compares the real-time material parameters with the preset qualified standard threshold, and distinguishes qualified quartz sand material from unqualified waste material containing large particle impurities. Step 3: The visual inspection system determines that the quartz sand material is qualified. No rejection operation is required. It falls naturally along the material channel inside the ore color sorter and falls into the first guide bucket at the top of the L-shaped support frame at the finished product discharge position. This allows the qualified quartz sand to fall steadily and centrally onto the surface of the finished product conveyor belt. The finished product conveyor belt then continuously and directionally transports the quartz sand, completing the independent conveying operation of the pure finished quartz sand. Step 4: For the large particle impurities and unqualified quartz sand waste detected and identified, the controller responds at high speed and triggers the high-pressure jet removal mechanism inside the equipment to blow the waste away from the normal material channel and push it to the waste material discharge position of the ore color sorter, so that it falls into the second guide bucket reinforced by the support frame. After the initial flow is guided by the second guide bucket, it enters the telescopic chute at the bottom, completing the directional collection and transportation of the waste. Step 5: Adaptive anti-splash and anti-overflow conveying adjustment for waste materials. During operation, the controller controls the periodic extension and retraction of the reciprocating electric push rod fixed by the boss, which drives the push plate and collar to drive the telescopic chute to swing back and forth. At the same time, the connecting frame at the bottom of the telescopic chute slides along the groove of the arched guide rail through the slider. When the telescopic chute slides to the low position on both sides of the guide rail, the drop of the material in the chute is reduced, which greatly reduces the kinetic energy of the material hitting the waste conveyor belt. At the same time, the outlet of the connecting frame faces the center of the conveyor belt to avoid the waste splashing to the side. The sliding rod moves down and pulls the horizontal plate, so that the sliding plate slides down vertically along the limit rod, which drives the top plate, guide block and conical adjusting plug to move down synchronously, enters the material channel to reduce the flow cross-sectional area, reduces the waste discharge speed and instantaneous discharge volume, and reduces the problem of material overflow at the edge. Finally, the waste falls stably to the waste conveyor belt body through the telescopic chute, completing the centralized layered conveying of impurities and waste. The whole process realizes the precise layering and stable diversion of quartz sand finished product and waste.

[0015] Compared with the prior art, the present invention has the following advantages: This invention utilizes an arched guide rail combined with a reciprocating telescopic chute structure. When the chute is offset to the lower areas on both sides of the conveyor belt, it can appropriately reduce the vertical drop of the material, effectively weakening the impact energy of large particles hitting the conveyor belt. At the same time, the outlet of the telescopic chute can remain facing the center of the conveyor belt during the offset state, which helps to reduce the splashing and scattering of large particles to the outer edge of the conveyor belt. This reduces the loss of quartz sand raw materials to a certain extent and maintains a clean workshop environment. In addition, it is equipped with an adaptive feeding speed regulation structure that can be adjusted in conjunction with the sliding position of the chute. It can adapt to the feeding conditions according to the actual spatial layout after the chute is offset. When the telescopic chute slides to both sides of the conveyor belt, the feeding area is relatively concentrated, and the buffer space is limited, the sliding rod can be linked to the horizontal plate to move down, driving the conical adjusting plug to extend into the material channel. This appropriately reduces the material flow cross-sectional area, reduces the instantaneous feeding speed and feeding amount of waste, and alleviates the material overflow and accumulation jamming risks that are easily caused by the constant feeding amount and concentrated feeding on one side of the traditional equipment.

[0016] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0020] Example 1:

[0021] like Figures 1 to 8 As shown, a quartz sand layered conveying device based on visual inspection includes an ore color sorter 1 containing a visual inspection system, and a finished material conveyor belt body 5 and a waste material conveyor belt body 8 are provided at the material discharge position of the ore color sorter 1. A second guide hopper 9 is installed on the waste conveyor belt body 8. A telescopic chute 11 is installed at the bottom of the second guide hopper 9. A push plate 16 is installed on the waste conveyor belt body 8. The push plate 16 is used to drive the telescopic chute 11 to swing back and forth, thereby changing the feeding position and preventing waste from falling and colliding with each other, which would cause waste to splash. A guide rail 20 is also installed on the waste conveyor belt body 8. The guide rail 20 is arched. The bottom of the telescopic chute 11 is slidably set in the guide rail 20, and the highest point of the guide rail 20 is located at the center of the waste conveyor belt body 8. When it moves to slide on both sides of the guide rail 20, the vertical distance between the telescopic chute 11 and the waste conveyor belt body 8 is reduced, which reduces the kinetic energy of the material hitting the conveyor belt and causing splashing. Its outlet faces the center of the waste conveyor belt body 8, which reduces the situation of material scattering to the outside. A horizontal plate 23 is vertically slidably installed on the waste conveyor belt body 8, and the horizontal plate 23 is slidably connected to the bottom of the telescopic chute 11. When the telescopic chute 11 moves to both sides of the guide rail 20, it drives the adjusting plug 31 located inside the second guide bucket 9 to move down, thereby reducing the material discharge speed and reducing the occurrence of raw material spillage.

[0022] like Figures 1 to 8 As shown in the specific embodiment, a positioning frame 2 is installed at the bottom of the ore color sorter 1. Several pairs of reinforcing ribs are also installed on the upper part of the positioning frame 2. An adjusting rod 3 is also installed at the bottom of the positioning frame 2 by bolts. A pad 4 is installed at the bottom of the adjusting rod 3, and the pad 4 is in the shape of a boss. An indicator light 33 is installed on the ore color sorter 1, and a controller 32 is also installed on the side wall of the ore color sorter 1. The positioning frame 2 and the adjusting rod 3 with the pad 4 can realize the overall horizontal leveling and stable support of the equipment. The reinforcing ribs can improve the structural strength of the equipment frame. At the same time, the controller 32 and the indicator light 33 can monitor and display the operating status of the equipment in real time, which is convenient for the staff to monitor the overall working condition of the machine in real time and ensure the long-term stable operation of the equipment.

[0023] like Figures 1 to 8 As shown, the ore color sorter 1 further includes a feed inlet 34 at its top, and an observation window 35 is installed on the outer casing of the color sorting position. The feed inlet 34 ensures stable feeding of quartz sand raw materials, and the observation window 35 at the color sorting position allows operators to easily and intuitively observe the color sorting and material identification status inside the equipment in real time, promptly detect any abnormal operating conditions, and improve the controllability and ease of maintenance of the equipment.

[0024] Example 2:

[0025] The difference between the above embodiments and this embodiment is that: Figures 1 to 8As shown, a support frame 7 is installed on the finished material conveyor belt body 5. The support frame 7 is L-shaped, and a first guide bucket 6 is installed on the top of the support frame 7. The first guide bucket 6 corresponds to the finished material discharge position of the ore color sorter 1, and a second guide bucket 9 corresponds to the waste material discharge position of the ore color sorter 1. A bracket 10 for support is also installed on the side wall of the second guide bucket 9. By fixing the first guide bucket 6 with the L-shaped support frame 7 and reinforcing the second guide bucket 9 with the bracket 10, the finished material and waste material discharge channels are precisely aligned. This allows for the collection and guidance of qualified quartz sand and impurity waste materials, preventing material dispersion and spillage, achieving precise stratified and diverted conveying of finished and waste materials, and improving the regularity of the sorting and conveying process.

[0026] like Figures 1 to 8 As shown in the specific embodiment, a collar 15 is installed on the top of the push plate 16. The collar 15 is sleeved on the outer wall of the telescopic chute 11. A reciprocating electric push rod 13 is provided on the outer wall of the collar 15. A boss 14 for support is installed on the outer shell of the reciprocating electric push rod 13, and the reciprocating electric push rod 13 is used to drive the push plate 16 to swing back and forth. The boss 14 provides stable support for the reciprocating electric push rod 13. Together with the collar 15 and the push plate 16, they form a linkage drive structure, which can stably drive the telescopic chute 11 to swing back and forth in a regular manner. This provides reliable power support for dynamic adjustment of the material feeding position and anti-splash operation. The structure has stable transmission and a low failure rate.

[0027] like Figures 1 to 8 As shown, a connecting frame 12 is further installed at the bottom of the telescopic chute 11, a slider 19 is installed on the side wall of the connecting frame 12, and a sliding rod 18 is installed at the end of the slider 19. A strip groove 17 is also provided on the push plate 16, and the strip groove 17 is slidably connected to the sliding rod 18. Fixed seats 22 are installed at both ends of the guide rail 20, and the fixed seats 22 are installed at both ends on the outer frame of the waste conveyor belt body 8. A sliding groove 21 is provided on the guide rail 20, and the sliding groove 21 is slidably connected to the slider 19. The guide rail 20 is securely installed by the fixed seats 22. By utilizing the sliding cooperation of the slider 19, the sliding groove 21, the sliding rod 18 and the strip groove 17, the reciprocating sliding process of the telescopic chute 11 can be guaranteed to be smooth and stable, effectively limiting the sliding trajectory, avoiding deviation and jamming, and ensuring the continuity and stability of the dynamic feeding adjustment action.

[0028] Example 3:

[0029] The difference between the above embodiments and this embodiment is that: Figures 1 to 8As shown, a slot 27 is formed on the horizontal plate 23, and a slide rod 18 is slidably installed inside the slot 27. Slide plates 24 are installed at both ends of the horizontal plate 23, and limit rods 25 are movably installed through the slide plates 24. The limit rods 25 are in a vertical state, and the bottom of the limit rods 25 are installed on the outer frame of the waste conveyor belt body 8. A limit plate 26 is installed on the top of the limit rods 25. The cross-sectional area of ​​the limit plate 26 is larger than that of the limit rods 25. The limit plate 26 is used to prevent the slide plates 24 from separating from the limit rods 25. By adapting the linkage displacement of the slide rods 18 through the slot 27, and with the limit rods 25 and the limit plate 26, the slide plates 24 are vertically limited and guided, ensuring that the horizontal plate 23 slides up and down accurately, without deviation or falling off, providing a stable mechanical linkage basis for the subsequent adaptive adjustment of the material flow rate.

[0030] like Figures 1 to 8 As shown, in a specific embodiment, a top plate 28 is installed on the horizontal plate 23, and the top plate 28 is movably connected to the second guide hopper 9. A guide block 29 is installed at the center of the top plate 28, and the top of the guide block 29 has an inclined surface 30. An adjusting plug 31 is installed at the bottom of the guide block 29, which is aligned with the telescopic chute 11. The adjusting plug 31 is conical. By driving the guide block 29 and the conical adjusting plug 31 to rise and fall synchronously through the top plate 28, the cross-sectional area of ​​the material flow inside the second guide hopper 9 and the telescopic chute 11 can be dynamically changed, realizing adaptive control of the feeding speed. At the same time, the inclined surface 30 of the guide block 29 can guide the material, reduce the accumulation and jamming of large particles and impurities, and ensure a smooth and stable feeding adjustment process.

[0031] This invention also discloses a method for layered conveying of quartz sand based on visual inspection, the steps of which are as follows: Step 1: Start the whole machine through the controller 32 on the side wall of the ore color sorter 1. The indicator light 33 will light up simultaneously and show the standby working status of the equipment. The staff can check the internal working condition of the equipment through the observation window 35. After the debugging is completed, put the quartz sand raw material to be sorted into the feed port 34 at the top of the ore color sorter 1. Step 2: The quartz sand raw material is fed into the ore color sorter 1 and falls evenly and flat. The high-speed and high-definition vision detection module built into the equipment scans the material flow frame by frame at a high frame rate, and collects the particle size, shape and outline, and gray color difference data of the quartz sand in real time. It accurately identifies large particles with excessive particle size, agglomerated impurities, hard sand and gravel lumps and other large particle defects, and transmits the collected data to the controller 32 in real time. The controller 32 relies on the built-in high-precision particle identification algorithm to compare the real-time material parameters with the preset qualified standard threshold, and distinguishes qualified quartz sand material from unqualified waste material containing large particle impurities. Step 3: The visual inspection system determines that the quartz sand material is qualified. No rejection operation is required. It falls naturally along the material channel inside the ore color sorter 1 and falls into the first guide bucket 6 at the top of the L-shaped support frame 7 at the finished product discharge position. This allows the qualified quartz sand to fall steadily and centrally onto the surface of the finished product conveyor belt body 5. The finished product conveyor belt body 5 then continuously and directionally conveys the quartz sand, completing the independent conveying operation of the pure finished product quartz sand. Step 4: For the large particle impurities and unqualified quartz sand waste detected and identified, the controller 32 responds at high speed and triggers the high-pressure jet removal mechanism inside the equipment to blow the waste away from the normal material channel and push it to the waste material discharge position of the ore color sorter 1, so that it falls into the second guide bucket 9 reinforced and supported by the support 10. After the initial flow is guided by the second guide bucket 9, it enters the telescopic chute 11 at the bottom, completing the directional collection and conveying of waste. Step 5: Waste material adaptive anti-splash and anti-overflow conveying adjustment. During operation, the controller 32 controls the reciprocating electric push rod 13 fixed by the boss 14 to periodically extend and retract, driving the push plate 16 and collar 15 to drive the telescopic chute 11 to swing back and forth. At the same time, the connecting frame 12 at the bottom of the telescopic chute 11 slides along the slide groove 21 of the arched guide rail 20 through the slider 19. When the telescopic chute 11 slides to the low position on both sides of the guide rail 20, the material drop of the chute is reduced, which greatly reduces the kinetic energy of the material hitting the waste conveyor belt body 8. At the same time, the outlet of the connecting frame 12 faces the... To prevent waste from splashing sideways towards the center of the conveyor belt, the slide bar 18 moves down to pull the horizontal plate 23, causing the slide plate 24 to slide vertically down along the limit bar 25. This causes the top plate 28, guide block 29, and conical adjusting plug 31 to move down synchronously, entering the material channel to reduce the flow cross-sectional area, reducing the waste discharge speed and instantaneous discharge volume, and reducing the problem of material overflow at the edge. Finally, the waste falls stably down to the waste conveyor belt body 8 through the telescopic chute 11, completing the centralized layered conveying of impurities and waste. The entire process achieves precise layering and stable diversion of quartz sand finished products and waste.

[0032] The implementation principle of a vision-based quartz sand stratified conveying device of the present invention is as follows: When the equipment is running, the quartz sand raw material to be tested and sorted is fed into the feed port 34 at the top of the ore color sorter 1. The material quality is identified by the internal visual inspection system. The operator can view the internal color sorting operation status in real time through the observation window 35 on the side wall of the equipment. The controller 32 on the equipment serves as the core control unit to control the operation of the whole machine. The indicator light 33 displays the working status of the equipment in real time, which is convenient for the staff to monitor the operating conditions of the equipment in real time.

[0033] After precise sorting and identification by the internal visual inspection system of the ore color sorter 1, it can accurately identify and remove large particles of impurities in the quartz sand, completing the stratified sorting of qualified quartz sand and waste containing large particles of impurities. During operation, the quartz sand raw material is fed into the ore color sorter 1 and falls evenly and flat. The high-speed, high-definition visual inspection module scans the material flow frame by frame at a high frame rate, focusing on collecting the characteristics of large particles in the quartz sand material. Specifically, this includes coarse particles exceeding the particle size limit, agglomerated impurities, hard lumps of sand and gravel, and irregularly shaped large particles, etc. The real-time collected particle size, shape, and grayscale color difference data are transmitted to the controller 32. The controller 32 has a built-in high-precision particle identification algorithm that quickly compares the real-time detected particle parameters with the preset qualified particle size range and appearance standard threshold for quartz sand, accurately screening out large particles of impurities that exceed the specifications.

[0034] For qualified finished quartz sand with uniform particle size, no large impurities, regular shape, and meeting production standards, the visual inspection system determines it to be qualified material. No rejection action is required. The qualified quartz sand falls naturally along the material channel inside the ore color sorter 1, accurately aligning with the finished product discharge position of the ore color sorter 1, and falls into the first guide bucket 6 installed on the top of the L-shaped support frame 7. Through the gathering, guiding, and regulating limiting effect of the first guide bucket 6, the finished material is prevented from scattering and spilling. The finished quartz sand falls steadily and centrally onto the surface of the finished material conveyor belt body 5. The finished material conveyor belt body 5 continuously and directionally completes the conveying operation of the purified qualified quartz sand, realizing the independent and orderly conveying operation of pure finished material.

[0035] For various large particle impurities and unqualified quartz sand materials containing large particle impurities detected and identified, the controller 32 responds instantly and at high speed and triggers the high-pressure jet removal mechanism inside the equipment. It accurately blows the waste material containing large particle impurities away from the normal material channel and pushes it to the waste material discharge position of the ore color sorter 1, so that it falls into the corresponding matching second guide bucket 9. The second guide bucket 9 is reinforced and supported by the side wall bracket 10 to ensure the stability of the guiding structure. After being guided by the second guide bucket 9, the waste material containing large particle impurities enters the bottom telescopic chute 11 and is guided by the telescopic chute 11 to fall onto the surface of the waste conveyor belt body 8, thus completing the collection and transportation of large particle impurity waste. This realizes the automated and precise cleaning of large particle impurities in quartz sand raw materials and simultaneously completes the stratified diversion and transportation of qualified materials and impurity waste.

[0036] During the waste conveying process, the controller 32 controls the reciprocating electric push rod 13 to periodically extend and retract. The reciprocating electric push rod 13 is fixedly supported by the outer boss 14, and its output end is linked to the push plate 16 to achieve reciprocating swing. The push plate 16 is fixed to the outside of the telescopic chute 11 by the top collar 15, thereby driving the entire telescopic chute 11 to move back and forth synchronously. At this time, the internal slide rod 18 slides relative to the strip groove 17, while the slider 19 slides along the slide groove 21. When the telescopic chute 11 slides with the slider 19 to the highest point of the center of the guide rail 20, the distance between the bottom of the chute and the perimeter of the conveyor belt is uniform and there is sufficient space for diffusion. At this time, the kinetic energy of the material falling does not need to change.

[0037] When the telescopic chute 11 slides to the lower positions on both sides of the arched guide rail 20, the entire telescopic chute 11 sinks with the arc of the guide rail, the overall material drop is significantly reduced, and the impact kinetic energy of the material falling and hitting the conveyor belt is greatly reduced, which weakens the basic kinetic energy of material splashing from the source and further reduces the amount of splashing (because when it moves to the sides, the edge of one side of the waste conveyor belt body 8 is close to the material discharge position and is prone to splashing).

[0038] Furthermore, when the connecting frame 12 moves to both sides, the outlet of the connecting frame 12 is facing the center of the waste conveyor belt body 8, reducing the possibility of waste splashing out.

[0039] When the connecting frame 12 moves to both sides, the vertical height of the slide bar 18 on the connecting frame 12 decreases, and the horizontal plate 23 moves vertically downward, causing the top plate 28 to move vertically downward along the second guide hopper 9. The top plate 28 simultaneously drives the bottom guide block 29 and the adjusting plug 31 of the conical structure to move downward, penetrating into the material channel of the second guide hopper 9 and the telescopic chute 11, reducing the material flow cross-sectional area, actively reducing the waste discharge speed and the instantaneous discharge amount (because when it moves to both sides, the edge of one side of the waste conveyor belt body 8 is close to the discharge position, making it easy to overflow). Through this adaptive speed regulation structure, the spatial layout after the chute offset can be matched, avoiding the problem of material overflow and scattering caused by excessive empty space on one side and excessive discharge amount. Combined with the low-position small space anti-splash structure characteristics, it can fully adapt to the stable conveying of the entire stroke. At the same time, the inclined surface 30 on the top of the guide block 29 can guide the material, prevent material accumulation and jamming, and ensure the smoothness of the discharge adjustment process.

[0040] During the overall operation, the device accurately distinguishes between finished product and waste quartz sand through a visual inspection system, realizing the stratified and diverted conveying of the two types of materials.

10. A method for layered conveying of quartz sand based on visual inspection, characterized in that, A quartz sand stratified conveying device based on visual inspection, as described in any one of claims 1 to 9, and a quartz sand stratified conveying method based on visual inspection, comprising the following steps: Step 1: Start the whole machine through the controller (32) on the side wall of the ore color sorter (1). The indicator light (33) will light up simultaneously and show the standby working status of the equipment. The staff will check the internal working condition of the equipment through the observation window (35). After the debugging is completed, put the quartz sand raw material to be sorted into the feed port (34) at the top of the ore color sorter (1). Step 2: The input quartz sand raw material is evenly spread and falls inside the ore color sorter (1). The high-speed and high-definition visual detection module built into the equipment scans the material flow frame by frame at a high frame rate, and collects the particle size, shape and gray color difference data of quartz sand in real time. It accurately identifies large particles with excessive particle size, agglomerated impurities, hard sand and gravel blocks and other large particle defects, and transmits the collected data to the controller (32) in real time. The controller (32) relies on the built-in high-precision particle identification algorithm to compare the real-time material parameters with the preset qualified standard threshold, and distinguishes qualified quartz sand material from unqualified waste material containing large particle impurities. Step 3: The visual inspection system determines that the quartz sand material is qualified. No rejection operation is required. It falls naturally along the material channel inside the ore color sorter (1) and falls into the first guide bucket (6) at the top of the L-shaped support frame (7) at the finished product discharge position. This allows the qualified quartz sand to fall steadily and centrally onto the surface of the finished product conveyor belt body (5). The finished product conveyor belt body (5) then continuously and directionally conveys the quartz sand, completing the independent conveying operation of the pure finished quartz sand. Step 4: For the large particle impurities and unqualified quartz sand waste detected and identified, the controller (32) responds at high speed and triggers the high-pressure jet removal mechanism inside the equipment to blow the waste away from the normal material channel and push it to the waste material discharge position of the ore color sorter (1), so that it falls into the second guide bucket (9) reinforced by the support (10). After the second guide bucket (9) is initially guided, it enters the telescopic chute (11) at the bottom, completing the directional collection and transportation of waste. Step 5: Waste material adaptive anti-splash and anti-overflow conveying adjustment. During operation, the controller (32) controls the periodic extension and retraction of the reciprocating electric push rod (13) fixed by the boss (14), which drives the push plate (16) and collar (15) to drive the telescopic chute (11) to swing back and forth. At the same time, the connecting frame (12) at the bottom of the telescopic chute (11) slides along the groove (21) of the arched guide rail (20) through the slider (19). When the telescopic chute (11) slides to the low position on both sides of the guide rail (20), the drop of the chute is reduced, which greatly reduces the kinetic energy of the material hitting the waste conveyor belt body (8). At the same time, the connecting frame ( 12) The outlet faces the center of the conveyor belt to avoid the waste splashing to the side. The slide bar (18) moves down to pull the horizontal plate (23), so that the slide plate (24) slides down vertically along the limit bar (25), which drives the top plate (28), guide block (29) and conical adjusting plug (31) to move down synchronously, go deeper into the material channel to reduce the flow cross-sectional area, reduce the waste discharge speed and instantaneous discharge amount, reduce the problem of material overflow at the edge, and finally the waste falls stably to the waste conveyor belt body (8) through the telescopic chute (11), completing the centralized layered conveying of impurities and waste, and realizing the precise layering and stable diversion of quartz sand finished products and waste throughout the process.
