[0029] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0030] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0031] like Figure 1 and Figure 2As shown, the present invention provides an intelligent date sorting machine, including a frame 1. The frame 1 adopts a high-quality steel welding structure, and the structure is firm, which ensures the stability of the whole machine. At the same time, the bottom of the frame 1 adopts a Foma caster, which can make the whole machine move conveniently. The Foma caster has a brake and an adjustment foot cup, which can fix the machine. A plurality of profile tugboat sorting and conveying mechanisms 2 arranged side by side are installed in the frame 1. A blanking conveyor belt 3 is installed below the front of the profile tugboat sorting and conveying mechanism 2, and a plurality of discharging conveyor belts 4 arranged side by side are installed below the rear. The discharging direction of the discharging conveyor belt 4 is perpendicular to the conveying direction of the profile tugboat sorting and conveying mechanism 2 above. A visual inspection system 5 and a sorting mechanism 6 are sequentially arranged above the profile tugboat sorting and conveying mechanism 2 along the conveying direction. The sorting mechanism 6 is located directly above the discharging conveyor belt 4. A cleaning mechanism 7 is installed at the bottom of the profile tugboat sorting and conveying mechanism 2.

[0032] A hopper 8 is installed at the front end of the profiling tugboat sorting and conveying mechanism 2 on the frame 1. The hopper 8 adopts a stainless steel sheet metal welding structure and is used to store and guide red dates. A residual material conveyor belt 9 is installed at the tail of the profiling tugboat sorting and conveying mechanism 2 inside the frame 1, and a return material conveyor belt 10 is installed on one side outside the frame 1. One end of the return material conveyor belt 10 is connected to the hopper 8, and the other end is connected to the residual material conveyor belt 9. The residual material conveyor belt 9 is used to collect unsorted red dates and return them to the hopper 8 through the return material conveyor belt 10. A cam reciprocating feeding mechanism 11 is installed between the front end of the profiling tugboat sorting and conveying mechanism 2 and the frame 1. The cam reciprocating feeding mechanism 11 is located directly below the hopper 8.

[0033] like Figure 3 As shown, the profiling tugboat sorting and conveying mechanism 2 is composed of a transmission assembly 2-1, a conveying chain 2-2, a profiling tugboat 2-3, a separation brush assembly 2-4 and a tugboat brush assembly 2-5. The profiling tugboat 2-3 is installed between the conveying chains 2-2 on both sides and is driven by the transmission assembly 2-1 for conveying. The separation brush assembly 2-4 is installed above the front profiling tugboat 2-3, and the tugboat brush assembly 2-5 is fixedly installed at the bottom of the upper profiling tugboat 2-3.

[0034] Through the above technical scheme, the conveying motor in the transmission component 2-1 drives the conveying chain 2-2 to operate through the active sprocket and the driven sprocket, and the contoured tugwheel 2-3 between the conveying chains 2-2 moves forward as a whole as the chain moves forward. At the same time, the contoured tugwheel 2-3 rotates under the friction force of the tugwheel brush component 2-5 at the bottom, making it easier for red dates to fall between the contoured supporting wheels 2-3. At the same time, the separation brush component 2-4 will cause the excess red dates to separate from the contoured supporting wheels 2-3, making the arrangement of the red dates more uniform, and finally there will be only one red date between the two contoured supporting wheels 2-3.

[0035] like Figure 5As shown, the visual inspection system 5 is composed of a visual camera 5-1 and a condenser 5-2. The upper end of the visual camera 5-1 is fixed on a fixed plate 5-3, and the condenser 5-2 is installed on a mounting plate 5-4. The fixed plate 5-3 and the mounting plate 5-4 are connected and fixed. The camera end of the visual camera 5-1 extends into the condenser 5-2, and an internal light source is provided inside the condenser 5-2. The visual camera 5-1 uses a high-resolution CCD camera and is connected to the background image analysis and processing system, which can quickly and accurately determine the size, shape, color, completeness, etc. of the red dates.

[0036] like Figure 6 and Figure 7 As shown, the sorting mechanism 6 is composed of a shield 6-1, a sorting blow plate 6-2 and a fixed profile 6-3. The shield 6-1 is vertically arranged side by side above the profiling tugboat sorting and conveying mechanism 2. The sorting blow plate 6-2 is vertically arranged in the shield 6-1 and corresponds to each profiling tugboat sorting and conveying mechanism 2. One side of the sorting blow plate 6-2 is provided with a blowing hole 6-4 corresponding to each discharge conveyor belt 4. The top of each two ends of each shield 6-1 is connected and fixed to the frame 1 through a shield connector 6-5, and the two ends of each sorting blow plate 6-2 are connected and fixed to the fixed profile 6-3 through a blow plate connector 6-6.

[0037] Through the above technical scheme, the sorting blowing plate 6-2 is connected to the compressed air through the high-speed solenoid valve, and in combination with the detection results of the visual detection system 5, different red dates can be blown off from the contoured tugboat sorting conveying mechanism 2 at the corresponding positions through the blowing holes 6-4, and under the blocking of the protective cover 6-1, they fall into different discharge conveyor belts 4 respectively.

[0038] like Figure 8 As shown, the cleaning mechanism 7 is composed of a lifting cylinder 7-1, a bracket 7-2, and a brush plate 7-3. Both ends of the bracket 7-2 are connected to the output end of the lifting cylinder 7-1 through a connecting rod 7-4. Brush plates 7-3 are installed at equal intervals on the bracket 7-2, and a brush 7-5 is provided on the end surface of each brush plate 7-3. After transporting red dates, the profiling roller 2-3 will adhere to some dirt. At regular intervals, the lifting cylinder 7-1 rises, and the profiling roller 2-3 will be rubbed by the brush 7-5 when passing through the brush plate 7-3. At this time, it can be washed with water to wash off the dirt, so that the profiling roller 2-3 is guaranteed to be clean and enter the next sorting cycle.

[0039] like Fig. 9As shown, the cam reciprocating feeding mechanism 11 includes a camshaft 11-1, a cam 11-4, a connecting screw 11-6 and a swing plate 11-8. The camshaft 11-1 is sleeved in a bearing seat 11-2, and the bearing seat 11-2 is fixedly connected to the frame 1. A transmission sprocket 11-3 is sleeved in the middle of the camshaft 11-1, and the cam 11-4 is installed at the end of the camshaft 11-1. The cam 11-4 is connected to one end of the connecting screw 11-6 through a joint bearing 11-5, and the other end of the connecting screw 11-6 is hinged on a hinge seat 11-7, and the hinge seat 11-7 is fixedly installed on the swing plate 11-8. The upper edge of the swing plate 11-8 is hinged on a fixing member 11-9 through a hinge, and the fixing member 11-9 is fixedly connected to the frame 1.

[0040] Through the above technical scheme, the transmission sprocket 11-3 is connected to one of the driven sprocket shafts of the transmission component 2-1 through a chain. When the transmission component 2-1 starts to operate, it will drive the transmission sprocket 11-3 to rotate, thereby driving the camshaft 11-1 and the cam 11-4 to rotate. At this time, the joint bearing 11-5 will reciprocate with the cam 11-4, and the swing plate 11-8 will be pushed to swing back and forth, thereby pushing the stacked red dates to be spread out, which is convenient for sorting the red dates.

[0041] like Figure 4 As shown, the blanking conveyor belt 3 is arranged horizontally, and a long guide plate 3-1 and a short guide plate 3-2 are arranged side by side and tilted along the conveying direction on both sides of the blanking conveyor belt 3, and a blanking baffle 3-3 is installed at one end of the blanking conveyor belt 3. The blanking conveyor belt 3 is used to collect the red dates that fall through the gap during loading and before sorting.

[0042] Working principle and process: The conveying motor in the transmission component 2-1 will drive the conveying chain 2-2 to operate through the active sprocket and the driven sprocket, and the contoured tug 2-3 will be conveyed forward with the conveying chain 2-2. At this time, the separation brush component 2-4 cooperates with the tug brush component 2-5 to sort the accumulated red dates individually. When the red dates on the conveyor line pass through the visual inspection system 5, the visual inspection system will quickly and accurately determine the category of the red dates, and then the sorting mechanism 6 will blow the different red dates to the corresponding discharge conveyor belt 4 through the blowing hole 6-4 for collection. Among them, the red dates (most of which are not up to standard) and debris that are separated from the conveyor line before sorting are collected through the drop conveyor line 3, which keeps the entire production line clean and tidy, reduces manual work, and is conducive to maintaining the continuity of production; a few red dates that have not been sorted continue to be transported forward, fall onto the residual material conveyor belt 9, and then transported to the return material conveyor belt 10, and return to the hopper 8 through the return material conveyor belt 10. When the contoured roller sorting conveying mechanism 2 is transferred to the lower return section along the conveying line, the cleaning mechanism 7 cleans the contoured rollers 2-3.

[0043] In summary, the present invention can sort and transport individual red dates, effectively preventing the friction problem of red dates and avoiding damage to the red dates. At the same time, it can sort and collect dates of different qualities one by one without manual secondary sorting, thereby improving sorting efficiency and reducing labor costs. In addition, the overall integrated design has a compact structure and adopts automatic control to realize automatic production. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
