[0060] The structure and working principle of the utility model are further described in combination with the embodiments.

[0061] Embodiment 1:

[0062] The material sorting execution system in the embodiment comprises a PLC control unit, a feeding mechanism 100, a conveying mechanism 200, a detection mechanism 300, an execution sorting mechanism 400 and a material distribution bin 600.

[0063] The feeding mechanism 100 is arranged at the head end of the material sorting system to provide the material to the conveying mechanism 200.

[0064] The discharge port of the feeding mechanism 100 is connected with the head end of the conveying mechanism 200; the detection mechanism 300 is arranged in the rear section of the conveying mechanism 200 to send the screening information of the obtained ore to the PLC control unit to control the execution sorting mechanism 400 to sort.

[0065] The material distribution bin 600 for receiving the sorted material is arranged at the tail end of the conveying mechanism 200; the execution sorting mechanism 400 is arranged between the conveying mechanism 200 and the material distribution bin 600.

[0066] The PLC control unit is connected with the feeding mechanism 100, the conveying mechanism 200, the detection mechanism 300 and the execution sorting mechanism 400 respectively to realize the control of different actions of the mechanisms.

[0067] The execution sorting mechanism 400 comprises a nozzle 409 and a gas storage tank 410.

[0068] The nozzle 409 is fixedly arranged between the tail end of the conveying mechanism 200 and the material distribution bin 600; the height of the nozzle 409 is lower than the installation height of the conveying mechanism 200 and higher than the bin body height of the material distribution bin 600.

[0069] An electric valve is arranged at the outlet of the nozzle 409; the electric valve is connected with the PLC control unit to realize the control of the opening size of the electric valve through the PLC control unit, thereby realizing the control of the blowing strength.

[0070] The gas storage tank 410 is arranged below the conveying mechanism 200 and connected with the nozzle 409 through a gas pipe.

[0071] The embodiment 1 describes the structure design of the execution sorting mechanism, and the working principle is as follows:

[0072] The material sorting process starts from the feeding mechanism 100, which is located at the first end of the whole system, and the function is to stably and uniformly convey the ore material to be sorted to the conveying mechanism 200 according to the set rate and mode. The discharge port of the feeding mechanism 100 is closely connected with the first end of the conveying mechanism 200, so as to ensure that the material can smoothly enter the next process and avoid the accumulation or flow interruption of the material.

[0073] The conveying mechanism 200 usually adopts a conveyor belt device. The hopper at the first end of the conveyor belt receives the material from the feeding mechanism 100, and the material moves to the end of the system at a stable speed along with the continuous operation of the conveyor belt. When the material runs to the middle and rear section of the conveyor belt, the detection mechanism 300 arranged at this position starts to play a key role. The laser emitter 301 in the detection mechanism 300 emits a laser beam of a specific wavelength, which is vertically downwardly irradiated on the surface of the ore material on the conveyor belt. The photodiode detector 302 located vertically below the laser emitter 301 receives the laser signal reflected by the ore in real time. Since the reflection characteristics of the laser of the ore of different particle sizes and materials are different, the reflection light information obtained by the detector 302 is also different. These light signals are quickly processed and analyzed by the processor, and the key screening information such as the profile shape and size of the ore is converted into an electrical signal and transmitted to the PLC control unit in real time.

[0074] The PLC control unit as the “brain” of the whole system receives the ore information from the detection mechanism 300, makes a judgment according to the preset sorting program and parameters, and sends accurate control instructions to the execution sorting mechanism 400. According to the instruction action of the PLC control unit. If the ore of a certain particle size or characteristic needs to be sorted, the PLC control unit controls the electric valve at the outlet of the nozzle 409 to open, and accurately adjusts the opening size of the electric valve according to the specific situation of the ore. The greater the opening, the faster the gas flow rate and the greater the flow rate of the gas delivered from the gas tank 410 to the nozzle 409, and the stronger the air flow force blown out, and vice versa. When the ore is thrown out from the end of the conveyor belt at an initial speed in the horizontal direction, the different characteristics of the ore will change the flight trajectory due to different forces. The ore meeting the sorting requirements is blown to a specific area of the material bin 600, the waste rock is blown into the waste rock groove 601, and the useful ore is blown into the ore groove 602.

[0075] The sorting bin 600 is located at the end of the conveying mechanism 200. Waste rock troughs 601 and ore troughs 602 are arranged sequentially, both having the same size and shape, and their horizontal orientation is coaxial with the transport direction of the conveying mechanism 200. The intermediate partition plate 500 effectively prevents the mixing of different materials, ensuring that the sorted waste rock and ore fall precisely into their respective troughs, achieving efficient and orderly material collection and greatly facilitating subsequent processing. Through close cooperation and coordinated operation between the various mechanisms, the entire system achieves rapid and accurate sorting of ore materials, effectively improving the efficiency and quality of ore pre-disposal waste treatment.

[0076] Example 2:

[0077] This embodiment of a material sorting execution system includes: a PLC control unit, a feeding mechanism 100, a conveying mechanism 200, a detection mechanism 300, an execution sorting mechanism 400, and a material sorting bin 600;

[0078] Its specific connection structure is the same as in Embodiment 1, the difference being the structure of the sorting mechanism 400, specifically as follows: Figure 2 The diagram shown is a structural schematic of the sorting mechanism in this embodiment. Further, in this embodiment, the sorting mechanism 400 includes: a device housing 401, a connecting mechanism 402, a transition fixing device 403, a small particle blowing mechanism 404, a large particle blowing mechanism 405, a solenoid valve 406, an air storage and return device 407, and a fixing frame 408.

[0079] The device housing 401 is fixed on the fixed frame 408. The connecting mechanism 402 is mounted on the device housing 401 through the intermediate fixing device 403 to adjust the fixing angle of the connecting mechanism 402. The intermediate fixing device 403 is a commercially available product, and its function is only to adjust the fixing angle of the connecting mechanism 402. It can be a support frame, support stud, etc.

[0080] The connecting mechanism 402 is attached to the end of the conveying mechanism 200 to receive the material conveyed by the conveying mechanism 200;

[0081] At the outlet of the connection port 402, a small particle blowing mechanism 404 and a large particle blowing mechanism 405 are arranged side by side. The small particle blowing mechanism 404 and the large particle blowing mechanism 405 are respectively connected to the gas storage return device 407 through a solenoid valve 406 installed in the device housing 401. The solenoid valve 406 is connected to the PLC control unit to open the small particle blowing mechanism 404 or the large particle blowing mechanism 405 according to the instructions of the PLC control unit.

[0082] like Figure 3As shown, the small particle size blowing mechanism and the large particle size blowing mechanism in an embodiment are schematically shown, the small particle size blowing mechanism 404 is a plurality of rectangular air outlets, the rectangular air outlets are arranged side by side, and the interval between adjacent two rectangular air outlets is 1mm-2mm;

[0083] The large particle size blowing mechanism 405 is a plurality of circular air outlets, the circular air outlets are arranged side by side, and the center distance between adjacent two circular air outlets is 8mm-10mm.

[0084] The array length of the air outlet of the small particle size blowing mechanism 404 and the large particle size blowing mechanism 405 is greater than or equal to the width of the connecting mechanism 402.

[0085] The connecting mechanism 402 is a hollow cube structure with a trapezoidal cross section, the short side is an outlet, and the long side is a feeding port, which is attached to the end of the conveying mechanism 200 to receive the material after detection by the detection mechanism 300 and perform sorting.

[0086] In the embodiment, the detection mechanism 300 detects the size of the selected mineral, and selects different sorting methods based on the size of the selected mineral to perform sorting, that is, selects different blowing methods to perform blowing.

[0087] The sorting mechanism 400 performs sorting on the thrown mineral based on the result identified by the detection mechanism 300, so that the waste rock and the ore fall into the waste rock groove 601 and the ore groove 602 respectively, and the sorting of the waste rock or the ore is realized. Specifically, the sorting mechanism 400 is a blowing mechanism, which blows the selected mineral or the unselected mineral according to the result identified by the monitoring mechanism 300, so as to change the motion trajectory of the selected mineral or the unselected mineral, so that the selected mineral or the unselected mineral deviates from the original parabolic motion trajectory, and the selected mineral and the unselected mineral are sorted out. As Figure 3 As shown, the execution end of the sorting mechanism 400 can be arranged in the material distribution bin 600, and the sorting mechanism 400 is connected with the detection mechanism 300 to receive the identification result of the detection mechanism 300, so as to blow the selected mineral or the unselected mineral according to the identification result, that is, the sorting mechanism 400 blows the same kind of mineral, so that the motion trajectory of the mineral deviates from the motion trajectory of another kind of mineral, that is, the separation of the two kinds of minerals is realized, and then the selected mineral is obtained. The sorting mechanism 400 is arranged at the tail of the material sorting system to perform mineral sorting.

[0088] Figure 2The specific details of the implementation sorting mechanism are shown in the figure, where 402 is the connection between the transportation system and the implementation system, which can be made of wear-resistant and corrosion-resistant materials, not fixed materials, and the material can be selected according to the customer's on-site demand and processing capacity. The angle and size can be adjusted by the excess position fixing device 403, but the angle is usually fixed. In the figure, 403 is the excess position fixing device, the head is completely consistent with the plane of the excess material, so as to prevent the angle of the material in the air from changing after the material leaves the transportation system during transportation. The important thing is that the connection mechanism 402 and the excess position fixing device 403 can prevent the boring card from being stuck in the gap and causing the equipment to be paralyzed. Figure 2 The small particle size blowing mechanism 404 and the large particle size blowing mechanism 405 are used to determine the implementation method and the implementation quantity by setting the particle size vertically after identifying the vertical projection shape.

[0089] Figure 2 In the figure, 406 is an electromagnetic valve, and the type and size of the air jet valve are not fixed and can be changed according to the actual production needs. For example, Figure 2 As shown in the figure, it is a straight electromagnetic valve, and the flow and type of the small particle size blowing mechanism 404 and the large particle size blowing mechanism 405 are not the same, and the electromagnetic valve 406 is arranged directly below the air jet port. Eight air jet ports are arranged in a group, and the air jet port can be connected to the small particle size blowing mechanism 404 and the large particle size blowing mechanism 405 through different material hoses. The compressed gas used by the air jet valve is transmitted from the outside to the storage reflux device 407, and when the small particle size blowing mechanism 404 and the large particle size blowing mechanism 405 need to be implemented, the compressed gas is obtained from the storage reflux device 407.

[0090] Figure 3 The details of the air jet port of the small particle size blowing mechanism 404 and the large particle size blowing mechanism 405 are shown in the figure. In this embodiment, the small particle size blowing mechanism 404 is set as a rectangular air jet port with a width of 1mm and a length of 3mm, and the interval is 1mm. The large particle size blowing mechanism 405 is set as a circular air jet port with a diameter of 4mm, and the center distance is 8mm. It should be understood that the figure is only an implementation scheme compatible with small particle size and large particle size blowing, and the size and shape can be changed and designed according to specific requirements.

[0091] Based on the structure of the implementation sorting mechanism 400, the working principle of embodiment 2 is as follows:

[0092] The feeding mechanism 100 is arranged at the first end of the material sorting system (such as Figure 1The left end, i.e. upstream, the material is provided to the conveying mechanism 200. Among them, the feeding mechanism 100 corresponds to the feed inlet of the whole material sorting system, and is arranged at the front end of the material sorting system. In this embodiment, the feeding mechanism 100 is also used for pre-screening of the minerals, i.e. pre-throwing, to screen out waste in the minerals; and using friction to convey and adjust the material, so that the material can be thrown out at the output end of the conveying mechanism 200 with an initial horizontal speed, so that the minerals fall into the distribution bin 600 with a parabolic trajectory. Among them, the material conveying mechanism 200 belongs to the middle region of the material sorting system, and is used for conveying the minerals to the discharge outlet for discharging the minerals. In this embodiment, the material separation plate 500 is arranged in the distribution bin 600;

[0093] When the material to be sorted is stably transmitted from the feeding mechanism 100 to the identification system, the transmitting end 301 of the detection mechanism 300 irradiates the material and penetrates the belt to transmit information to the receiving end 302, and the receiving end 302 sends the acquired vertical projection shape image to the terminal. The vertical projection refers to the projection generated by mutually parallel light rays, and the parallel light rays are perpendicular to the projection plane. The projection information acquired by the same piece of material entering the identification system in any posture will not differ greatly. It should be understood that there are many ways to obtain the vertical projection, and the ultimate goal is to obtain the two-dimensional information and characteristic information of the material on the belt.

[0094] After determining the execution information, the points with the farthest distance up and down and left and right are found from the projection shape of the vertical plane respectively, and a line segment is drawn along the vertical direction and the vertical direction. After the intersection of the two points, four right angles will be formed, and the projection shape will be evolved into a rectangular frame. The length and the short side of the rectangular frame are used to determine the particle size of the material. The sorting conditions meeting the large particle size blowing mechanism are executed by the circular hole air jet valve, and the sorting conditions meeting the small particle size blowing mechanism are executed by the long strip-shaped air jet valve.

[0095] Based on the vertical projection information, the spatial coordinates and the projection shape of the small particle size blowing mechanism 404 and the large particle size blowing mechanism 405 are obtained. For example, as shown in Figure 2 The diameter of the air jet hole of the large particle size blowing mechanism 405 is 4mm, the center distance of the hole is 8mm, and it is assumed that the particle size of the material a meets the sorting condition of the large particle size blowing mechanism, and the vertical direction length is 50mm. After being transported to the blowing mechanism by the belt, there will be at least 6 air jet valves, and at most 7 air jet valves will blow air when passing through the center of the material to sort the material. As shown in Figure 2 The length of the air jet hole of the small particle size blowing mechanism 404 is 3.5mm, the width is 1mm, and the interval is 2.5mm. It is assumed that the particle size of the material b meets the sorting condition of the small particle size blowing mechanism, and the vertical direction length is 20mm. After being transported to the blowing mechanism by the belt, there will be at least 5 air jet valves, and at most 6 air jet valves will blow air when passing through the center of the material to sort the material.

[0096] For small size and large size blowing port to be executed: the center point of the projection shape is determined based on the projection information of the material to be sorted, the center point is the center position of the cuboid (cubic) composed of the most prominent points on the projection image; the center point is taken as the hitting position, and the blowing time is determined according to the length of the material, and the number of blowing points is determined according to the shape of the material.

[0097] According to the material threshold value, whether to execute is selected. If the material meets the pre-set threshold value, it is marked as an execution material, and if it does not meet the threshold value, it is marked as a non-execution material. The execution material will be executed after the midpoint corresponds to the air valve after passing through the blowing system, and will be blown into the 602 concentrate tank, and vice versa. The non-execution material will fall at 601.

[0098] In summary, according to the structure of the utility model and the structure of the execution sorting mechanism in the two embodiments, the utility model sets small size blowing mechanism and large size blowing mechanism for different particle size ores. The small size blowing mechanism adopts closely arranged rectangular air jet (adjacent interval 1mm-2mm), and the large size blowing mechanism is a circular air jet (circle center distance 8mm-10mm) suitable for large particles, and the air jet array length guarantees comprehensive coverage of the material flow. The air jet mode can be flexibly selected according to the particle size difference of the ore, the target ore can be accurately blown off, the phenomenon of being carried or kicked is avoided, and the sorting efficiency is greatly improved.

[0099] Although the preferred embodiments of the utility model have been described, those skilled in the art can make further changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model. Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model also intends to include these modifications and variations.
