Description

Technical Field

[0001] The present invention relates to the technical field of sorting equipment, and specifically relates to an intelligent optoelectronic sorting material intermediate-large-and-two-side-small sieve distribution device. Background Art

[0002] Mined mineral resources such as coal, tungsten ore, manganese ore, etc. are often accompanied by tailings and must be sorted before they can be utilized. The sorting device based on optoelectronic technology can process materials without consuming water and has gradually emerged in China. However, for the current optoelectronic sorting equipment for bulk materials, the materials are randomly arranged in terms of particle size during the feeding process. The sorting principle is to identify the materials through X-ray transmission to achieve sorting. The X-ray is a point light source, and the X-ray is diffusely irradiated from above the conveyor belt towards the middle and both sides of the conveyor belt. Under the chaotic arrangement, for example, when relatively large materials are distributed on both sides of the belt, there will be occlusion and misidentification, and there will also be a large distortion of the shape after imaging, which is not conducive to the identification and positioning in the sorting process, resulting in a low recognition rate and a decline in the effect of removing tailings after sorting.

[0003] Therefore, our team has designed and developed an intelligent optoelectronic sorting device with regular material arrangement. Through the rotation of the inclined screening spiral ring, the materials inside the screening spiral ring can flow out along different pitch gaps to achieve screening. Since the pitch of the screening spiral ring increases sequentially in the axial direction, the sizes of the screened materials can flow out in an arrangement with increasing sizes. Although the regular arrangement of the materials can solve the problem of light source occlusion on one side, there will still be a situation where large materials occlude small materials on the other side, affecting the identification.

Specific embodiments

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] As Figures 1 to 11 shown, the present invention includes the following embodiments:

[0034] Embodiment 1: An intelligent optoelectronic sorting material middle-large and both-sides-small sieve distribution device, including a fabric box 1 and a fabric support 11 arranged below the fabric box 1; a feed inlet 12 is arranged at the upper end of the fabric box 1; a discharge outlet 13 is arranged on the front side of the fabric box 1; a plurality of material guide plates 2 are uniformly arranged from top to bottom at the discharge outlet 13; the discharge ends 21 of the plurality of material guide plates 2 are gradually distributed towards both sides from top to bottom; the height of the material guide plate 2 decreases as it is farther away from the fabric box 1; a vibrating fabricator 3 is received below the discharge end 21 of the material guide plate 2; a plurality of fabric members 4 are arranged inside the fabric box 1 from top to bottom; the number of the fabric members 4 is the same as the number of the material guide plates 2 arranged; the height of the fabric member 4 increases as it is farther away from the material guide plate 2; the position of the front part of the upper surface of the fabric member 4 corresponds to the position of the feed end 22 of the material guide plate 2; the fabric member 4 includes a plurality of fabric belts 41 that are driven front and back; the plurality of fabric belts 41 are evenly distributed in the left and right directions and form a fabric gap 42; the width of the fabric gap 42 on the fabric member 4 decreases successively from bottom to top.

[0035] In this embodiment, the fabric member 4 further includes a rotating roller 5, a rotating sleeve 6, and a fabric sleeve 7; the number of the rotating rollers 5 is two, one of the rotating rollers 5 is arranged at the front, and the other rotating roller 5 is arranged at the rear; the rotating roller 5 is rotatably connected to the left and right groove walls of the fabric box 1; the rotating roller 5 is driven by a motor 51; the number of the rotating sleeves 6 is the same as that of the rotating rollers 5; the rotating sleeve 6 is sleeved and connected to the outer wall of the rotating roller 5; the number of the fabric sleeves 7 is the same as that of the fabric belts 41; the fabric belt 41 is in an annular shape, such as an annular metal chain; the fabric sleeve 7 is sleeved and connected to the outer wall of the rotating sleeve 6; the fabric belt 41 is drivingly connected to the outer walls of the two corresponding fabric sleeves 7 at the front and rear; the upper surface of the fabric belt 41 is driven to move from front to back during transmission.

[0036] In this embodiment, two material removing rings 71 are arranged on the outer wall of the fabric sleeve 7; the fabric belt 41 on the outer wall of the fabric sleeve 7 is located between the two corresponding material removing rings 71; the distance between the two material removing rings 71 on the outer wall of the fabric sleeve 7 is adapted to the width of the fabric belt 41 in the left and right directions; the outer edge of the material removing ring 71 protrudes from the outer edge of the fabric belt 41.

[0037] After the motor 51 is started, the motor 51 drives the roller 5 connected to the motor 51 to rotate. During the rotation of the roller 5, the rotating sleeve 6 connected to the outer wall is driven to rotate. During the rotation of the rotating sleeve 6, the fabric sleeve 7 sleeved and connected to the outer wall is driven to rotate. During the rotation of the fabric sleeve 7, the fabric belt 41 is driven to move. The upper surface of the fabric belt 41 moves from front to back, and the height of the fabric belt 41 increases as it moves away from the material guiding plate 2. The transmission speed of the fabric belt 41 is less than the forward movement speed of the material on the upper surface of the fabric belt 41. As the material is poured into the feeding port 12 of the fabric box 1, the material will first fall on the upper surface of the uppermost fabric piece 4. Taking the number of the fabric piece 4 and the material guiding plate 2 as three as an example, the fabric pieces 4 from top to bottom are sequentially named the first fabric piece 4, the second fabric piece 4, and the third fabric piece 4. After the material falls on the upper surface of the first fabric piece 4, since the fabric piece 4 is inclined forward and there is a fabric gap 42 provided by the fabric belt 41, when the material rolls forward along the upper surface of the first fabric piece 4, the material smaller than the fabric gap 42 on the first fabric piece 4 will fall onto the upper surface of the second fabric piece 4, and the material larger than the fabric gap 42 on the first fabric piece 4 will roll forward along this fabric piece 4. In order to extend the movement time of the material on the fabric piece 4, the upper surface of the fabric belt 41 moves from front to back, so as to reserve enough time for the screening of the material, realize the full classification of the material, and improve the classification effect. Of course, the transmission speed of the fabric belt 41 is less than the forward movement speed of the material, so that the material can smoothly move from the upper surface of the fabric piece 4 to the corresponding material guiding plate 2. The large material sliding down from the upper surface of the first fabric piece 4 will enter the first material guiding plate 2 from top to bottom. The discharge end 21 of the first material guiding plate 2 is located at the middle position of the discharge port 13, so that the material on the first material guiding plate 2 will fall into the middle position of the vibrating fabricator 3 and continue to move under the vibration of the vibrating fabricator 3; the material falling on the upper surface of the second fabric piece 4 will continue to move forward along the upper surface. The material smaller than the fabric gap 42 on the second fabric piece 4 will pass through this fabric gap 42 and fall onto the upper surface of the third fabric piece 4, and the material larger than the fabric gap 42 on the second fabric piece 4 will slide along this fabric piece 4 and enter the second material guiding plate 2. The medium material enters along the feeding end 22 of the second material guiding plate 2 and flows out along the discharge end 21. The discharge end 21 of the second material guiding plate 2 is more biased towards both sides compared with the discharge end 21 of the first material guiding plate 2, so that the material on the second material guiding plate 2 will be biased towards both sides after falling into the vibrating fabricator 3 and continue to move under the vibration of the vibrating fabricator 3;The materials that fall on the upper surface of the third fabric piece 4 will continue to move forward along the upper surface. The materials smaller than the fabric gap 42 of the third fabric piece 4 will pass through the fabric gap 42 and fall to the bottom of the fabric box 1 for collection. A discharge door can be provided at the bottom of the fabric box 1 to facilitate the removal of materials. The materials larger than the fabric gap 42 of the third fabric piece 4 will slide along the upper surface of the fabric piece 4 and enter the third guide plate 2. The small materials enter along the feed end 22 of the third guide plate 2 and flow out along the discharge end 21. The discharge end 21 of the third guide plate 2 is more biased towards both sides compared to the discharge end 21 of the second guide plate 2, so that the materials on the third guide plate 2 are more biased towards both sides after falling into the vibrating fabricator 3 and continue to move under the vibration of the vibrating fabricator 3. The vibration of the vibrating fabricator 3 will not affect the confusion of large and small materials in the left and right directions. Materials of different specifications will move forward smoothly and stably under the vibration of the vibrating fabricator 3. The discharge end 21 of the guide plate 2 will not affect the material falling at this height. Specifically, a buffer can be provided in the vibrating fabricator 3 to reduce the rebound of the falling materials. In addition, the fabric belt 41 in the fabric piece 4 is continuously driven. The front and rear positions of the fabric belt 41 are drivingly connected to the outer wall of the corresponding fabric sleeve 7. During the driving process, the material removal ring 71 on the outer wall of the fabric sleeve 7 can remove the materials stuck on the fabric belt 41 to prevent the blockage of materials in the fabric gap 42 from affecting the subsequent screening of materials and make the fabric more stable. The materials removed from the fabric gap 42 will continue to move forward along the upper surface of the fabric piece 4. The number of the fabric piece 4 and the guide plate 2 in the present invention is not limited to three, and can be four, five or more. The specific number is set and adjusted according to the classification requirements of the materials. In this way, when the number of the fabric piece 4 is multiple, each fabric piece 4 can intercept materials of corresponding specifications, and the intercepted materials will flow out along their respective guide plates 2. The discharge ends 21 of the multiple guide plates 2 are biased towards both sides from top to bottom, so that the materials falling on the vibrating fabricator 3 are arranged with a large middle and small sides. After passing through the vibrating fabricator 3, the materials fall onto the conveyor belt. The image acquisition and processing device will acquire images and analyze them to distinguish coal and gangue, and finally cooperate with the nozzle to blow air to blow the ore into different receiving modules;

[0038] The present invention screens and intercepts materials of different specifications through the fabric gaps 42 with different spacings, so that the materials are classified and fall into different guide plates 2. Under the guidance of the discharge ends 21 at different positions of the guide plates 2, the materials are arranged with a large middle and small sides after falling on the vibrating fabricator 3, thus avoiding the problem of light source blocking when identifying materials, and improving the ray identification accuracy and sorting accuracy;

[0039] In the present invention, by controlling the forward-backward transmission of the upper surface of the cloth belt 41, and at the same time, the transmission speed of the cloth belt 41 is less than the forward movement speed of the material, the screening time of the material by the cloth member 4 is prolonged, so that the material can be fully screened and classified, improving the classification effect; in addition, the material stuck in the cloth gap 42 is removed by the material removal ring 71, thus avoiding the influence of the material stuck in the cloth gap 42 on the subsequent screening of the material and making the cloth more stable.

[0040] Embodiment 2: The end of the rotating roller 5 extends to the outside of the cloth box 1; the outer wall of the rear rotating roller 5 is fixedly connected with a driven gear 52; the motor 51 is fixedly connected to the outer wall on the side of the cloth box 1; the output shaft of the motor 51 is fixedly connected with a driving gear 53; the driving gear 53 and a plurality of driven gears 52 are meshed and driven by a chain 54; the specifications of the driven gears 52 increase sequentially from top to bottom.

[0041] After the motor 51 is started, it will drive the driving gear 53 to rotate. During the rotation of the driving gear 53, it will drive the chain 54 to drive. The driven gear 52 and the driving gear 53 are driven by the chain 54. Therefore, the driven gear 52 will be driven by the chain 54 to rotate. The driven gear 52 is an annular gear. The rotation of the driven gear 52 will drive the rear rotating roller 5 to rotate. During the rotation of the rear rotating roller 5, it will drive the rotating sleeve 6 and the cloth sleeve 7 on the outer wall of the rotating sleeve 6 to rotate. During the rotation of the cloth sleeve 7, it will drive the cloth belt 41 to drive. Since the specifications of the plurality of driven gears 52 increase sequentially from top to bottom, the rotation speed of the lower driven gear 52 is less than the rotation speed of the upper driven gear 52. In this way, the transmission speed of the lower cloth belt 41 is less than the transmission speed of the upper cloth belt 41. After the material is filtered from top to bottom and falls on the upper surface of the corresponding cloth member 4, the material will gradually decrease. Therefore, the less the material needs to be filtered, the less time it takes. Therefore, by adapting the transmission speed of the cloth belt 41 from top to bottom to the screening time of the material, the forward movement efficiency of the material at the lower position is ensured, and the cloth efficiency is ensured.

[0042] Embodiment 3: The outer wall of the rotating roller 5 is provided with a notch 55 along the axial direction; a strip 56 is slidably connected in the notch 55; the strip 56 is fixedly connected to the inner wall of the rotating sleeve 6; the rotating sleeve 6 can slide along the axial direction of the rotating roller 5; one end of the rotating sleeve 6 facing left and the left inner wall of the cloth box 1 are abutted by a first spring 61; the first spring 61 is sleeved on the outer wall of the rotating roller 5; one end of the rotating sleeve 6 facing right is fixedly connected with a movable block 62 with a first guide surface 63; the right inner wall of the cloth box 1 is fixedly connected with a fixed block 64 with a second guide surface 65 corresponding to the movable block 62; the first guide surface 63 and the second guide surface 65 can be in contact with each other.

[0043] In this embodiment, the left and right tank walls of the fabric box 1 bulge outward to form an avoidance groove 14; the avoidance groove 14 corresponds to the end of the rotating roller 5 and is rotatably connected; the end of the rotating sleeve 6 is located in the corresponding avoidance groove 14; the fabric belt 41 near the end of the rotating sleeve 6 can enter the avoidance groove 14.

[0044] During the rotation of the rear rotating roller 5, the front rotating roller 5 will rotate along with the rear rotating roller 5. The rotating rotating roller 5 will drive the outer wall notch 56 and the rotating sleeve 6 to rotate. During the rotation of the rotating sleeve 6, the movable block 62 at the right end will be driven to rotate. During the rotation of the movable block 62, the first guiding surface 63 will contact the second guiding surface 65 on the fixed block 64. Under the inclined guiding extrusion of the first guiding surface 63 and the second guiding surface 65, the rotating sleeve 6 will drive the notch 56 to slide along the corresponding notch 55. The rotating sleeve 6 will move leftward along the outer wall of the rotating roller 5 and squeeze the corresponding first spring 61. After the movable block 62 passes over the fixed block 64, the first spring 61 will push the rotating sleeve 6 to move rightward along the outer wall of the rotating roller 5. The rotating sleeve 6 will drive the notch 56 to slide along the notch 55 again. After the movable block 62 passes by the fixed block 64 again, the rotating sleeve 6 will move leftward again. In this way, the rotating sleeve 6 will move back and forth axially along with the rotation of the rotating roller 5. The two corresponding rotating sleeves 6 before and after will move back and forth in the left-right direction. In this way, the multiple fabric belts 41 in the first fabric piece 4 will move back and forth in the left-right direction. In this way, the materials falling on the upper surface of the fabric piece 4 will be quickly spread out under the left-right fluctuation, avoiding accumulation and affecting screening, and improving the fabric effect; the end of the rotating sleeve 6 on the outer wall of the rotating roller 5 extends into the corresponding avoidance groove 14, so that even if the rotating sleeve 6 generates axial movement, the end of the rotating sleeve 6 will not move out of the avoidance groove 14. In this way, smaller materials can only pass through the fabric gap 42 and move downward, improving the fabric stability.

[0045] Embodiment 4: An adjustment groove 66 is axially penetrated through the outer wall of the rotating sleeve 6; an adjustment bar 67 is slidably connected to the adjustment groove 66 along the radial direction; the end of the adjustment bar 67 extends out from the end of the notch 55; a second spring 68 is connected between the surface of the adjustment bar 67 facing the center of the rotating sleeve 6 and the groove wall of the adjustment groove 66; a first tooth 69 is provided on the surface of the adjustment bar 67 facing away from the center of the rotating sleeve 6; an adjustment block 72 is slidably connected to the adjustment groove 66 along the length direction; the adjustment block 72 is fixedly connected to the inner wall of the corresponding fabric sleeve 7; a second tooth 73 is provided at the end of the adjustment block 72 away from the fabric sleeve 7; the first tooth 69 is engaged with the second tooth 73.

[0046] In this embodiment, an elastic sleeve 8 is sleeved on the outer wall of the rotating sleeve 6; the elastic sleeve 8 is connected between two adjacent fabric sleeves 7 on the outer wall of the rotating sleeve 6; the elastic sleeve 8 can block the adjustment groove 66.

[0047] In this embodiment, an annular strip 81 is fixedly connected to the end of the elastic sleeve 8; an annular groove 74 is correspondingly arranged at the end of the fabric sleeve 7 and the elastic sleeve 8; the annular strip 81 is rotatably connected in the annular groove 74.

[0048] In this embodiment, the distance from the adjusting strip 67 to the outer wall of the rotating sleeve 6 is less than the radius of the rotating sleeve 6; the adjusting strip 67 is subjected to centrifugal force after the rotating sleeve 6 rotates.

[0049] Before using the fabric device to fabricate materials, first move the adjusting strip 67 along the adjusting groove 66 and slide it closer to the center of the rotating sleeve 6. During the sliding process of the adjusting strip 67, it is necessary to overcome the elastic force of the second spring 68. During the process of the adjusting strip 67 approaching the center of the rotating sleeve 6, it will drive the first tooth 69 to disengage from the second tooth 73, so that the adjusting block 72 is unlocked. In this way, the adjusting block 72 can move along the length direction of the adjusting groove 66. During the movement of the adjusting block 72, it will drive the fabric sleeve 7 to move axially along the outer wall of the rotating sleeve 6. In this way, the fabric gaps 42 on each fabric piece 4 can be adjusted. The elastic sleeves between adjacent fabric sleeves 7 are elastic, so it will not affect the movement of the fabric sleeve 7. After the size of the fabric gap 42 is adjusted, release the adjusting strip 67. The second spring 68 will transfer the elastic force to the adjusting strip 67. The adjusting strip 67 will move away from the center of the rotating sleeve 6. The adjusting strip 67 will drive the first tooth 69 to contact and engage with the second tooth 73, so as to lock the adjusting block 72. In this way, the adjusting block 72 is locked in the length direction of the adjusting groove 66, and the fabric sleeve 7 is locked in the axial direction on the outer wall of the rotating sleeve 6. In this way, the size of the fabric gap 42 is locked. After the material is poured on the upper surface of the fabric piece 4, the fabric gaps 42 of different sizes can intercept and screen materials of different specifications. The elastic sleeve 8 can shield and protect the adjusting groove 66 to prevent materials from getting stuck; since the end of the elastic sleeve 8 is rotatably connected in the annular groove 74 through the annular strip 81, when the elastic sleeve 8 is in contact with the material, the elastic sleeve 8 will not rotate with the rotation of the fabric sleeve 7 under the friction of the material, so that the material can move forward smoothly and fall into the corresponding guide plate 2, while reducing the damage of the elastic sleeve 8 and improving the service life; during the rotation of the rotating roller 5 and the rotating sleeve 6, the adjusting strip 67 will be subjected to centrifugal force, so that the adjusting strip 67 will cooperate with the elastic force of the second spring 68 under the action of centrifugal force to make the first tooth 69 and the second tooth 73 engage more tightly, so that the adjusting block 72 and the fabric sleeve 7 are further locked; in this embodiment, by adjusting the axial position of the fabric sleeve 7 on the outer wall of the rotating sleeve 6, the fabric device can fabricate materials of more specifications, greatly improving the fabric range of the fabric device and improving the practicability.
