Description

Technical Field

[0001] The invention relates to the technical field of sorting equipment, in particular to an intelligent photoelectric sorting material distribution device with a large screen in the middle and small screens on both sides. Background Art

[0002] Mined mineral resources such as coal, tungsten ore, manganese ore, etc. are often accompanied by tailings, which must be sorted before they can be used. Sorting devices based on photoelectric technology can process materials without consuming water, and are gradually being used in my country. However, the current photoelectric sorting equipment for bulk materials uses random particle size arrangement when laying out the materials. The sorting principle is to use X-ray transmission to identify materials for sorting. X-rays are point light sources. X-rays are scattered from the top of the conveyor belt to the middle and both sides of the conveyor belt. Under chaotic arrangement, for example, when relatively large materials are distributed on both sides of the belt, they will be blocked and misidentified. It will also cause a large distortion of the shape after imaging, which is not conducive to identification and positioning during sorting. Ultimately, it results in a low recognition rate and a reduced effect of removing tailings after sorting.

[0003] To this end, our team has designed and developed an intelligent photoelectric sorting device with regular material arrangement. The device rotates the inclined screening spiral coil so that the material inside the screening spiral coil can flow out along the gaps with different pitches for screening. Since the pitch of the screening spiral coil increases successively in the axial direction, the specifications of the screened material can flow out in a successively increasing material arrangement. Although the regular arrangement of the material can solve the problem of light source obstruction on one side, there will still be a situation where large materials obstruct small materials on the other side, affecting identification.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 11 As shown, the present invention includes the following embodiments: Embodiment 1: An intelligent photoelectric sorting material distribution device with a large screen in the middle and small screens on both sides, comprising a distribution box 1 and a distribution bracket 11 arranged below the distribution box 1; a feed port 12 is arranged at the upper end of the distribution box 1; a discharge port 13 is arranged at the front side of the distribution box 1; the discharge port 13 is evenly arranged with a plurality of guide plates 2 from top to bottom; the discharge ends 21 of the plurality of guide plates 2 are gradually distributed toward both sides from top to bottom; the height of the guide plates 2 is set to decrease as they are away from the distribution box 1; the discharge end 21 of the guide plates 2 is supported below The vibrating cloth distributing device 3 is provided; a plurality of cloth pieces 4 are arranged on the inner side of the cloth box 1 from top to bottom; the number of the cloth pieces 4 is consistent with the number of the guide plate 2; the height of the cloth piece 4 is arranged to increase as it is away from the guide plate 2; the front position of the upper surface of the cloth piece 4 corresponds to the position of the feed end 22 of the guide plate 2; the cloth piece 4 includes a plurality of cloth belts 41 that drive forward and backward; the plurality of cloth belts 41 are evenly distributed in the left and right directions and form a cloth gap 42; the width of the cloth gap 42 on the cloth piece 4 decreases from bottom to top.

[0023] In this embodiment, the cloth member 4 also includes a roller 5, a rotating sleeve 6, and a cloth sleeve 7; there are two rollers 5, one of which is arranged at the front and the other is arranged at the rear; the roller 5 is rotatably connected to the left and right groove walls of the cloth box 1; the roller 5 is driven by a motor 51; the number of rotating sleeves 6 is consistent with the number of rollers 5; the rotating sleeve 6 is sleeved on and connected to the outer wall of the roller 5; the number of cloth sleeves 7 is consistent with the number of cloth belts 41; the cloth belt 41 is in the shape of an annular belt, such as an annular metal chain; the cloth sleeve 7 is sleeved on and connected to the outer wall of the rotating sleeve 6; the cloth belt 41 is transmission-connected to the outer walls of the two corresponding cloth sleeves 7 at the front and rear; the upper surface of the cloth belt 41 is transmitted from front to back under transmission.

[0024] In this embodiment, two pick-up rings 71 are provided on the outer wall of the fabric cover 7; the fabric belt 41 on the outer wall of the fabric cover 7 is located between the two corresponding pick-up rings 71; the spacing between the two pick-up rings 71 on the outer wall of the fabric cover 7 is adapted to the width of the fabric belt 41 in the left and right directions; the outer edge of the pick-up ring 71 protrudes from the outer edge of the fabric belt 41.

[0025] After the motor 51 is started, the motor 51 will drive 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 will be driven to rotate. During the rotation of the rotating sleeve 6, the cloth sleeve 7 set and connected to the outer wall will be driven to rotate. During the rotation of the cloth sleeve 7, the cloth belt 41 will be driven to transmit. The upper surface of the cloth belt 41 is transmitted from front to back. The height of the cloth belt 41 increases as it moves away from the guide plate 2. The transmission speed of the cloth belt 41 is less than the forward movement speed of the material on the upper surface of the cloth belt 41. As the material is poured into the feed port 12 of the cloth box 1, the material will first fall on the upper surface of the uppermost cloth piece 4, and the cloth piece 4 and the guide plate will be moved forward. Taking the setting number of three material plates 2 as an example, the cloth pieces 4 from top to bottom are named the first cloth piece 4, the second cloth piece 4 and the third cloth piece 4 in sequence. After the material falls on the upper surface of the first cloth piece 4, since the cloth piece 4 is tilted forward and a cloth gap 42 is provided through the cloth belt 41, when the material rolls forward along the upper surface of the first cloth piece 4, the material smaller than the cloth gap 42 on the first cloth piece 4 will fall to the upper surface of the second cloth piece 4, and the material larger than the cloth gap 42 on the first cloth piece 4 will roll forward along the cloth piece 4. In order to extend the activity time of the material on the cloth piece 4, The upper surface of the cloth belt 41 moves from front to back, thereby reserving enough time for the screening of the material, achieving full grading of the material and improving the grading effect. Of course, the transmission speed of the cloth belt 41 is lower than the forward moving speed of the material, so that the material can smoothly move from the upper surface of the cloth piece 4 to the corresponding guide plate 2. The large material sliding down from the upper surface of the first cloth piece 4 will enter the first guide plate 2 from top to bottom. The discharge end 21 of the first guide plate 2 is located in the middle position of the discharge port 13, so that the material on the first guide plate 2 will fall into the middle position of the vibrating cloth feeder 3 and continue to move under the vibration of the vibrating cloth feeder 3; the material falling on the upper surface of the second cloth piece 4 The material on the upper surface will continue to move forward along the upper surface, and the material smaller than the cloth gap 42 on the second cloth piece 4 will pass through the cloth gap 42 and fall to the upper surface of the third cloth piece 4, and the material larger than the cloth gap 42 on the second cloth piece 4 will slide along the cloth piece 4 and enter the second guide plate 2, and the material enters along the feeding end 22 of the second guide plate 2 and flows out along the discharging end 21. The discharging end 21 of the second guide plate 2 is biased to both sides compared with the discharging end 21 of the first guide plate 2, so that the material on the second guide plate 2 is biased to both sides after falling into the vibrating distributor 3, and continues to move under the vibration of the vibrating distributor 3;The material falling on the upper surface of the third cloth piece 4 will continue to move forward along the upper surface, and the material smaller than the cloth gap 42 of the third cloth piece 4 will pass through the cloth gap 42 and fall to the bottom of the cloth box 1 for collection. A material removal door can be provided at the bottom of the cloth box 1 to facilitate the removal of materials. The material larger than the cloth gap 42 of the third cloth piece 4 will slide along the upper surface of the cloth piece 4 and enter the third guide plate 2. The small material enters along the feed end 22 of the third guide plate 2 and flows out along the discharge end 21. The discharge end 21 of the third guide plate 2 is relatively The discharge end 21 of the second guide plate 2 is deflected to both sides again, so that the materials on the third guide plate 2 are more deflected to both sides after falling into the vibrating distributor 3, and continue to move under the vibration of the vibrating distributor 3. The vibration of the vibrating distributor 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 distributor 3. The discharge end 21 of the guide plate 2 will not affect the falling of materials at this height. Specifically, a buffer can be set in the vibrating distributor 3 to reduce the rebound of the falling materials. In addition, the cloth member 4 The cloth belt 41 is continuously driven, and the cloth belt 41 is connected to the outer wall of the corresponding cloth sleeve 7 at the front and rear positions. During the transmission process, the material removal ring 71 on the outer wall of the cloth sleeve 7 can remove the material stuck on the cloth belt 41 to prevent the material from being stuck in the cloth gap 42 and affecting the screening of subsequent materials, making the cloth more stable. The material removed from the cloth gap 42 will continue to move forward along the upper surface of the cloth piece 4; the number of cloth pieces 4 and guide plates 2 in the present invention is not limited to three, and can be four or five or more. The specific number depends on The material classification requirements are set and adjusted. In this way, when there are multiple distribution pieces 4, each distribution piece 4 can intercept materials of corresponding specifications. The intercepted materials will flow out along their respective guide plates 2. The discharge ends 21 of the multiple guide plates 2 are biased to both sides from top to bottom, so that the materials falling on the vibrating distributor 3 are arranged in a large middle and small on both sides. After passing through the vibrating distributor 3, the materials fall onto the conveyor belt. The image acquisition and processing device will collect and analyze the images to distinguish between coal and gangue. Finally, the nozzle will blow air to blow the mineral materials into different receiving modules. The present invention screens and intercepts materials of different specifications through the material distribution gaps 42 of different spacings, so that the materials fall into different guide plates 2 according to grade, and under the guidance of the discharge ends 21 of the guide plates 2 at different positions, the materials fall on the vibrating distributor 3 with a larger middle and smaller sides, thereby avoiding the problem of light source recognition causing obstruction of materials, thereby improving the ray recognition accuracy and sorting accuracy; The present invention controls the upper surface of the cloth belt 41 to transmit from front to back, and at the same time, the transmission speed of the cloth belt 41 is lower than the forward speed of the material, thereby extending the screening time of the material by the cloth member 4, so that the material can be fully screened and graded, and the grading effect is improved; in addition, the material stuck in the cloth gap 42 is removed by the removal ring 71, so as to avoid the material stuck in the cloth gap 42 affecting the screening of subsequent materials, and make the cloth more stable.

[0026] Embodiment 2: The end of the roller 5 extends to the outside of the fabric box 1; the outer wall of the roller 5 at the rear is fixedly connected to the driven gear 52; the motor 51 is fixedly connected to the lateral outer wall of the fabric box 1; the output shaft of the motor 51 is fixedly connected to the driving gear 53; the driving gear 53 is meshed with a plurality of driven teeth 52 through a chain 54 for transmission; the specifications of the driven teeth 52 increase from top to bottom.

[0027] After being started, the motor 51 will drive the active gear 53 to rotate, and the active gear 53 will drive the chain 54 to transmit during the rotation. The driven gear 52 and the active gear 53 are driven by the chain 54, so the driven gear 52 will be driven by the chain 54 to rotate. The driven gear 52 is an annular tooth. The rotation of the driven gear 52 will drive the roller 5 at the rear position to rotate. The rotation of the roller 5 at the rear position will drive the rotating sleeve 6 and the cloth sleeve 7 on the outer wall of the rotating sleeve 6 to rotate. The rotation of the cloth sleeve 7 will drive the cloth belt 41 to transmit. Due to the rotation of multiple driven teeth 52, The specifications increase from top to bottom, so that the rotation speed of the lower driven teeth 52 is less than the rotation speed of the upper driven teeth 52, so that 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, the material will gradually decrease after falling on the upper surface of the corresponding cloth piece 4. Therefore, the lower the material, the less time it needs to be filtered. Therefore, the transmission speed of the cloth belt 41 from top to bottom is adapted to the screening time of the material, thereby ensuring the forward movement efficiency of the material at the lower position, so that the cloth efficiency is guaranteed.

[0028] Embodiment 3: A notch 55 is provided on the outer wall of the roller 5 along the axial direction; a notch strip 56 is slidably connected in the notch 55; the notch strip 56 is fixedly connected to the inner wall of the rotating sleeve 6; the rotating sleeve 6 can slide axially along the roller 5; the left end of the rotating sleeve 6 is in contact with the left inner wall of the material box 1 through a first spring 61; the first spring 61 is sleeved on the outer wall of the roller 5; the right end of the rotating sleeve 6 is fixedly connected to a movable block 62 with a first guide surface 63; the right inner wall of the material box 1 is fixedly connected to 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 contact each other.

[0030] During the rotation of the rear roller 5, the front roller 5 will rotate with the rotation of the rear roller 5, and the rotating roller 5 will drive the outer wall missing strip 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 guide surface 63 will be driven to contact the second guide surface 65 on the fixed block 64. Under the inclined guide extrusion of the first guide surface 63 and the second guide surface 65, the rotating sleeve 6 will drive the missing strip 56 to slide along the corresponding missing groove 55, and the rotating sleeve 6 will move to the left along the outer wall of the 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 to the right on the outer wall of the roller 5, and the rotating sleeve 6 will drive the missing strip 56 to slide along the missing groove 55 again. After the movable block 62 passes the fixed block 64 again, the rotating sleeve 6 moves to the left again, so that the rotating sleeve 6 will move back and forth along the axial direction during the rotation of the roller 5, and the front and rear corresponding rotating sleeves 6 will move back and forth in the left and right directions, so that the multiple cloth belts 41 in the first cloth piece 4 will move back and forth in the left and right directions, so that the materials falling on the upper surface of the cloth piece 4 are quickly spread out under the left and right direction fluctuations, avoiding accumulation and affecting screening, so that the cloth effect is improved; the end of the rotating sleeve 6 on the outer wall of the roller 5 extends into the corresponding avoidance groove 14, so that even if the rotating sleeve 6 produces axial movement, the end of the rotating sleeve 6 will not move out of the avoidance groove 14, so that smaller materials can only pass through the cloth gap 42 and move downward, so that the cloth stability is improved.

[0031] Embodiment 4: An adjustment groove 66 is provided through the outer wall of the rotating sleeve 6 along the axial direction; the adjustment groove 66 is slidably connected to the adjustment bar 67 along the radial direction; the end of the adjustment bar 67 extends from the end of the notch 55; the adjustment bar 67 is connected to the groove wall of the adjustment groove 66 on the side facing the center of the rotating sleeve 6 through a second spring 68; the adjustment bar 67 is provided with a first tooth 69 on the side away from the center of the rotating sleeve 6; the adjustment groove 66 is slidably connected to the adjustment block 72 along the length direction; the adjustment block 72 is fixedly connected to the inner wall of the corresponding fabric sleeve 7; the adjustment block 72 is provided with a second tooth 73 at the end away from the fabric sleeve 7; the first tooth 69 is engaged with the second tooth 73.

[0034] In this embodiment, the distance between the adjustment bar 67 and the outer wall of the rotating sleeve 6 is smaller than the radius of the rotating sleeve 6 ; the adjustment bar 67 is subjected to centrifugal force after the rotating sleeve 6 rotates.

[0035] Before using the material distributing device to distribute the material, first, the adjusting bar 67 is toggled to slide along the adjusting slot 66 to move close to the center of the rotating sleeve 6. During the sliding process of the adjusting bar 67, the elastic force of the second spring 68 needs to be overcome. During the process of the adjusting bar 67 approaching the center of the rotating sleeve 6, the first tooth 69 and the second tooth 73 are driven to disengage, so that the adjusting block 72 is unlocked, so that the adjusting block 72 can move along the length direction of the adjusting slot 66. During the movement of the adjusting block 72, the distributing sleeve 7 is driven to move axially along the outer wall of the rotating sleeve 6, so that the cloth on each distributing piece 4 The gap 42 can be adjusted.
