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.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Embodiment 1

[0033] See also Figure 1 , an intelligent photoelectric sorting device for regular material arrangement, comprising a screen distribution device 1, a vibrating distributor 2, a conveyor belt 3, an image acquisition and processing device 4, an array nozzle 5 and a material receiving assembly 6, the vibrating distributor 2 is arranged below the screen distribution device 1, and receives the mineral material dispersed by the screen distribution device 1, the conveyor belt 3 is arranged below the vibrating distributor 2, the vibrating distributor 2 vibrates to further disperse the mineral material, and the dispersed mineral material is transported on the conveyor belt 3, the image acquisition and processing device 4 is arranged above the conveyor belt 3, the image acquisition and processing device 4 collects and analyzes the mineral material image, and distinguishes coal from gangue, the array nozzle 5 and the material receiving assembly 6 are both arranged at the end of the conveyor belt 3, the array nozzle 5 is arranged between the conveyor belt 3 and the material receiving assembly 6, two material receiving modules are arranged in the material receiving assembly 6, the array nozzle 5 blows according to the analysis result of the image acquisition and processing device 4, and blows the mineral material into different material receiving modules.

[0034] See also Figure 2The screening and distributing device 1 comprises a support frame 11, on which a screening drum 12 is arranged, one side of the screening drum 12 is higher, and a feed hopper 13 is arranged on the higher side, and the ore entering the feed hopper 13 slides into the screening drum 12 under the action of gravity, and the screening drum 12 is divided into multiple sections along the axial direction, from the higher side to the lower side, and the diameter of the screened particles in each section increases section by section, and according to the range of the feed particle size, the filter diameter can be set to 3-5 levels, and after the ore enters, the section with the smallest screened diameter screens out the powder, and a powder discharge hopper 18 is arranged at the corresponding position, and the powder discharge hopper 18 conveys the powder away, and the other side of the screening drum 12 A large material discharging chute 16 is provided at the end, and the large material discharging chute 16 transports away materials with too large diameters. A group of first support wheels 14 are respectively provided on both sides of the screening drum 12, and a driving wheel 1 is provided on one side of the screening drum 12. The first support wheels 14 support the screening drum 12. Each group of first support wheels 14 includes two, which are arranged at both ends of the screening drum 12. One group of first support wheels 14 is connected to a driving motor 15. The driving motor 15 drives the first support wheels 14 to rotate, and then drives the screening drum 12 to rotate, so that the mineral material in the screening drum 12 moves. In this embodiment, the first support wheel 14 on one side is used instead of the driving wheel 1 to realize the drive.

[0035] See also Figure 3 The size and spacing of the nozzles in the array nozzle 5 correspond to the screening cylinder 12. The array nozzles 5 corresponding to the positions for screening out large particles of mineral material have large nozzle apertures and large spacings. Conversely, the array nozzles 5 corresponding to the positions for screening out small particles of mineral material have small nozzle apertures and small spacings.

[0036] Since the ore material can easily cause the screen holes of the screen drum 12 to be blocked, please refer to Figure 4 In the present embodiment, the screen surface of the screening drum 12 is composed of a plurality of screening coils 124, each of which has a different pitch. The screening coils 124 with different pitches can screen out mineral materials of different diameters. Both ends of the screening coils 124 are fixedly connected with a rotating drum 121. The first support wheel 14 supports the screening drum 12 by supporting the rotating drum 121. A support shaft 122 is provided at the axis of the rotating drum 121. The support shaft 122 is connected to the rotating drum 121 and the screening coils 124 through a support rod 123. The support shaft 122 and the support rod 123 improve the structural strength of the screening coil 124 and enhance its load-bearing capacity.

[0037] See also Figure 2, an anti-blocking device 17 is provided above the screening drum 12. If ore materials are stuck on the screening drum 12, the anti-blocking device 17 will clean the ore materials when they reach the highest position, allowing the ore materials to have sufficient time to fall down by themselves, thereby reducing the noise and energy consumption generated when the ore materials collide with the anti-blocking device 17. The anti-blocking device 17 includes an anti-blocking spiral coil 172 corresponding to the screening spiral coil 124. The anti-blocking spiral coil 172 has the same pitch as the corresponding part of the screening spiral coil 124. A part of the anti-blocking spiral coil 172 is stuck in the interval of the screening spiral coil 124. The anti-blocking spiral coil 172 rotates synchronously with the screening spiral coil 124, so that the position of the part stuck in the screening spiral coil 124 relative to the screening spiral coil 124 remains unchanged. When the screening spiral coil 124 rotates, the anti-blocking spiral coil 172 will contact the ore materials stuck in the interval of the screening spiral coil 124 and make it fall back into the screening spiral coil 124. The anti-blocking spiral coil 172 is fixedly connected to the anti-blocking center shaft 171 through a support rod. The anti-blocking center shaft 171 is installed on the support frame 11. A synchronous transmission assembly 173 is provided on one side of the anti-blocking center shaft 171. The anti-blocking center shaft 171 is connected to the screening drum 12 through the synchronous transmission assembly 173. The synchronous transmission assembly 173 is a rigid transmission, and the two transmission wheels have the same diameter, ensuring that the anti-blocking center shaft 171 and the screening spiral coil 124 have the same rotation speed. Embodiment 2

[0038] In Example 1, when the mineral material is stuck on the screening spiral 124 and the screening spiral 124 rotates, it will contact the side of the anti-blocking spiral 172, which will cause a collision, noise and energy consumption. On the other hand, the screening spiral 124 is spiral and lacks axial support. The mineral material can be easily stuck in the gap and clamped by the axial elastic force of the screening spiral 124. For this reason, the anti-blocking device 17 is further improved on the basis of Example 1.

[0039] See also Figure 5 and Figure 6 The anti-blocking device 17 includes an anti-blocking spiral ring 176, the axis of which is located inside the screening spiral ring 124, a portion of which extends out of the anti-blocking spiral ring 176 from the interval of the anti-blocking spiral ring 176, the axis of the screening spiral ring 124 is located above the axis of the anti-blocking spiral ring 176, the anti-blocking spiral ring 176 and the screening spiral ring 124 have the same wheelbase at the corresponding positions, and the anti-blocking spiral ring 176 rotates synchronously with the screening spiral ring 124, After being screened out by the screening spiral coil 124, the mineral material will fall through the gap of the anti-blocking spiral coil 176. Generally speaking, the mineral material that can be successfully screened out by the screening spiral coil 124 can also be screened out by the anti-blocking spiral coil 176, and the mineral material will not be stuck on the anti-blocking spiral coil 176. In order to further avoid the mineral material being stuck on the anti-blocking spiral coil 176, the anti-blocking spiral coil 176 is made of elastic material. The anti-blocking spiral coil 176 does not bear the weight of the mineral material and does not play a screening role. The temporary deformation of the anti-blocking spiral coil 176 does not affect its use.

[0040] The outer ring of the anti-blocking screw ring 176 is provided with a cylindrical support frame 174 coaxial with the anti-blocking screw ring 176. The cylindrical support frame 174 has a sufficiently large gap so as not to interfere with the falling of the mineral material. The cylindrical support frame 174 is connected to the anti-blocking screw ring 176 through a support column 177. Since the cylindrical support frame 174 rotates synchronously with the screening screw ring 124, the position change range of the support column 177 relative to the screening screw ring 124 is small and will not collide with the screening screw ring 124. Both ends of the cylindrical support frame 174 are fixedly connected with a driven cylinder 175. Second support wheels 20 are provided on both sides of the driven cylinder 175. The second support wheel 20 is fixedly mounted on the support frame 11. The second support wheel 20 supports the cylindrical support frame 174. The driven cylinder 175 is also transmission-connected with a driving wheel 21. The driving wheel 21 drives the driven cylinder 175 to rotate, thereby driving the cylindrical support frame 174 and the anti-blocking screw ring 176 to rotate.

[0041] The driving wheel 21 is in driving connection with the first supporting wheel 14 which is in driving connection with the driving motor 15. The first supporting wheel 14 is close to the rotating cylinder 121. The driving wheel 21 is located between the driven cylinder 175 and the rotating cylinder 121. The driving wheel 21 is in contact with the inner wall of the driven cylinder 175. The rotating cylinder 121 is provided with a groove 125 for accommodating the driving wheel 21 so that the driving wheel 21 does not contact with the rotating cylinder 121. The transmission ratio between the driving wheel 21 and the driven cylinder 175 is the same as the transmission ratio between the first supporting wheel 14 and the rotating cylinder 121. In order to reduce the deformation of the anti-blocking spiral ring 176 and the screening spiral ring 124, both ends of the anti-blocking spiral ring 176 and the screening spiral ring 124 need to be driven. Please refer to Figure 4 In the present application, the two first support wheels 14 are driven by the transmission shaft 19, and the second driving wheel 21 is coaxial with the first support wheel 14, which can reduce one set of transmission shafts.

[0042] See also Figure 7 and Figure 8 In the first embodiment, when the stuck mineral material contacts the anti-blocking spiral coil 172, the speed of the anti-blocking spiral coil 172 at the mineral material position is greatly different from the movement direction of the mineral material, and a collision will occur. In the second embodiment, when the mineral material contacts the anti-blocking spiral coil 176, the movement directions of the two are almost the same. Combined with the elasticity of the screening spiral coil 124, the material is slowly pressed back into the screening spiral coil 124, the collision is small, the noise and energy consumption are reduced, and the service life of the screening spiral coil 124 is increased. Embodiment 3

[0043] See also Fig. 9In order to enhance the axial restraint ability of the screening spiral 124 and reduce material jamming, on the basis of the second embodiment, the screening cylinder 12 also includes 2-3 groups of restraint rods 126, each circle of the screening spiral 124 is fixedly connected to the restraint rod 126, and the restraint rod 126 is welded to the inner wall of the screening spiral 124. The support column 177 is elastic, and when the restraint rod 126 contacts the second anti-blocking spiral 176, no excessive impact force will be generated. At the same time, the support column 177 is elastic to ensure that the restraint rod 126 will not be blocked by the second anti-blocking spiral 176.
