Description

Technical Field

[0001] The present invention relates to the technical field of fruit black heart disease rating, and in particular to a pineapple black heart disease rating device and a rating method. Background Art

[0002] Pineapple belongs to the Bromeliaceae family and the genus Bromeliaceae. It is native to Brazil and Paraguay in South America and is distributed in tropical and subtropical regions. Pineapple's position in tropical fruit production and trade is second only to bananas and mangoes. Pineapples are produced in about 60 countries and regions in the world, and pineapples are one of China's most distinctive and competitive tropical fruits. However, black heart disease, a physiological disease, is very common in pineapples during storage and transportation after harvest. For a long time, experts and scholars at home and abroad have been committed to the research on pineapple black heart disease. Among them, grading the degree of black heart disease is an indispensable step. At present, the widely used black heart disease grading method is to cut the fruit in half longitudinally (split in the middle line in the direction of the major diameter) and conduct subjective visual observation to obtain the grading result.

[0003] However, the traditional, widely used method for grading pineapple blackheart has the following drawbacks: First, the pineapple is cut only along the longitudinal (largest diameter) midline, but the blackheart portion may be present on the cut surface or on other cross-sections; second, numerous investigations and studies have shown that pineapple blackheart disease does not always originate in the heart, but can also begin in the flesh; and third, the subjective assessment of the blackheart area is inevitably subject to human interference, resulting in unstable results. Therefore, the traditional pineapple blackheart grading method is prone to misjudgment, error, and instability, making it inaccurate for diagnosing and grading pineapple blackheart disease. Summary of the Invention

DETAILED DESCRIPTION

[0058] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments and drawings, but the protection scope and implementation methods of the present invention are not limited thereto. In the description of specific embodiments, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, or the directions or positional relationships in which the product of the invention is usually placed when in use, and the terms "Ⅰ", "Ⅱ", "Ⅲ", etc., are only used to distinguish the descriptions, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the structure or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention, let alone an indication or implication of relative importance.

[0059] Example 1

[0060] See also Figure 1 As shown, the pineapple black heart disease grading equipment of the embodiment of the present invention is sequentially provided with a pineapple leaf pre-cutting module 1, a pineapple slicing module 2, a detection and transportation module, a visual detection module 6 and an intelligent grading system module 7.

[0061] The pineapple leaf pre-cutting module 1 can pre-cut the pineapple leaves and fruit, separating the leaves from the fruit, while retaining only the fruit for further black heart disease grading. The pineapple slicing module 2 can slice the pineapple fruit longitudinally after the leaves have been pre-cut, that is, cut it into multiple petal-shaped slices along the major diameter. The sliced ​​pineapple fruit sliced ​​longitudinally by the pineapple slicing module 2 is inspected and transported by the inspection and transportation module. The visual inspection module 6 can perform online visual inspection on both sides of the sliced ​​pineapple fruit being transported online by the inspection and transportation module. The intelligent grading system module 7 is connected to the visual inspection module 6 and can grade the pineapple for black heart disease based on the inspection results of the visual inspection module 6, providing a pineapple black heart disease rating.

[0062] When grading pineapple black heart disease, the pineapple leaf pre-cutting module 1 first pre-cuts the pineapple to separate the fruit and leaves. The pineapple fruit after leaf pre-cutting is sent to the pineapple slicing module 2 for slicing. The sliced ​​pineapple fruit is then transported online by the inspection and transportation module. During the transportation process, the visual inspection module 6 performs online visual inspection on both sides of the sliced ​​pineapple fruit, and transmits the inspection information to the intelligent grading system module 7. Finally, the intelligent grading system module 7 performs rating calculations and gives the black heart disease grade.

[0063] Optional, see Figure 2 As shown, the pineapple leaf pre-cutting module 1 includes a feed trough 101, a pre-cutting disc 102 and a discharge trough 103. The feed trough 101 is open on both sides. Specifically, the feed trough 101 is composed of two feed guides with both feed ends turned outward. The feed guides with both feed ends turned outward can guide the pineapple to be fed horizontally along the large diameter direction; the pre-cutting disc 102 is arranged at a lower position on one side of the feed trough 101, and the pre-cutting disc 101 is loaded with a rotating cutting blade, and the cutting direction of the blade is perpendicular to the horizontal direction of the feed trough 101; the discharge trough 103 is arranged below the pre-cutting disc 101 and is located on the side of the pre-cutting disc 102 away from the feed trough 101, and the discharge trough 103 is designed to be an automatic unloading trough that tilts downward in the direction away from the feed trough 101.

[0064] When pre-cutting pineapple leaves, the pre-cutting knife disc 102 is started, and the major diameter direction of the pineapple is horizontally along the left and right sides of the feed trough 101, and the end containing the fruit leaves is toward the pre-cutting knife disc 102 side. The fruit leaves and the fruit to be cut are aligned with the blades on the pre-cutting knife disc 102, and the pineapple is placed from the feed trough 101. The blades on the pre-cutting knife disc 102 can complete the pre-cutting of the pineapple fruit leaves. The pre-cut fruit leaves fall into the discharge trough 103 and automatically slide down for discharge. The pineapple fruit after the fruit leaves are pre-cut by the pineapple fruit leaf pre-cutting module 1 will be transported to the pineapple slicing module 2 for slicing.

[0065] Further optionally, a feeding and transporting module 8 is provided between the pineapple leaf pre-cutting module 1 and the pineapple slicing module 2. In a specific embodiment, the feeding and transporting module 8 includes a motor and a conveyor belt driven by the motor. The feeding and transporting module 8 can transport the pineapple fruit after the leaf pre-cutting to the pineapple slicing module. The feeding and feeding end of the feeding and transporting module 8 is correspondingly located below the feeding trough 101, and the conveyor belt of the feeding and transporting module 8 is provided on a bracket Ⅰ9. The height of the bracket Ⅰ9 is higher than the pineapple slicing module 2, so that the feeding and discharging end of the feeding and transporting module 8 is relatively located above the pineapple slicing module 2. During operation, the pineapple fruit after the leaf pre-cutting by the pineapple leaf pre-cutting module 1 falls directly onto the feeding and transporting module 8. Then, when the pineapple fruit is transported to the discharging end of the feeding and transporting module 8 by the feeding and transporting module 8, it falls directly into the pineapple slicing module 2, completing the transportation of the pineapple fruit.

[0066] The pineapple fruits after pre-cutting of the leaves are prone to rolling during transportation. In order to prevent the pineapple fruits from falling off the conveying line of the feed and transport module 8 during transportation, the feed and transport module 8 is provided with a guard plate I 104 and a guard plate II 105 on the left and right sides, respectively, to protect the feed and transport module 8. The pre-cutting disc 102 and the discharge chute 103 are respectively located on the left and right sides of the guard plate I 104. Moreover, preferably, a notched knife table 1041 is provided on the guard plate I 104 corresponding to the feed chute 101. After the pineapple with pre-cut leaves is put into the feed chute 101, the part to be cut between the leaves and the fruit of the pineapple can be correspondingly fixed on the notched knife table 1041, so that the blade on the pre-cutting disc 102 can be quickly aligned and accurately cut.

[0067] Optionally, the pineapple slicing module 2 is arranged above the detection and transportation module. After the pineapple slicing module completes slicing, the sliced ​​pineapple fruits will directly fall onto the detection and transportation module and be detected and transported by the detection and transportation module.

[0068] Specifically, the pineapple slicing module 2 includes a material block box 201 and a slicing cutter disc 202. The material block box 201 is a box body with upper and lower openings, with the upper end being the feed end and the lower end being the discharge end. The slicing cutter disc 202 is located at the lower discharge end of the material block box 201. The pineapple fruits, pre-cut by the pineapple leaf pre-cutting module 1 and transported, fall into the material block box 201 and fall into the bottom discharge end of the material block box 201. After being sliced ​​by the slicing cutter disc 202 at the discharge end, the sliced ​​pineapple fruits fall directly into the detection and transportation module.

[0069] Among them, preferably, the material blocking box 201 is a funnel-shaped box that is open at the top and bottom and is wide at the top and narrow at the bottom, so that the material blocking box 201 can better receive the pineapple fruits dropped from the feeding and transporting module 8, and prevent them from falling out of the material blocking box 201. At the same time, the received pineapple fruits can be better concentrated at the discharge end of the material blocking box 201 so that they can be effectively sliced ​​by the slicing knife disc 202.

[0070] See also Figure 3 As shown, preferably, the slicing cutter disc 202 is a circular cutter disc with a diameter larger than the discharge end of the material blocking box 201, which blocks the bottom end of the material blocking box 201. The center of the slicing cutter disc 202 has a rotary cutting drive hole 2021, which can be driven and connected to the external drive mechanism, and the slicing cutter disc 202 is provided with a slicing blade 2022 running along the radial direction. Specifically, the slicing blade 2022 includes one or more pairs symmetrical along the rotary cutting drive hole 2021. During slicing, the output end of the external drive mechanism cooperates with the rotary cutting drive hole 2021, and drives the slicing cutter disc 202 to rotate, driving the slicing blade 2022 on the slicing cutter disc 202 to rotate and quickly complete the slicing of the pineapple fruit. After slicing, the sliced ​​pineapple fruit will fall directly from the slicing blade 2022 to the detection and transportation module.

[0071] Moreover, the slicing blade disc 202 can be replaced according to different requirements such as slice thickness.

[0072] Preferably, the detection and transportation module includes a connected detection and transportation module I3 and a detection and transportation module II4. The feed end of the detection and transportation module I3 is correspondingly located below the pineapple slicing module 2, and the discharge end of the detection and transportation module I3 is vertically connected with the feed end of the detection and transportation module II4. Specifically, the conveyor belt of the detection and transportation module I3 is set on the bracket II10, and the conveyor belt of the detection and transportation module II4 is set on the bracket III11. The height of the bracket II10 is higher than the height of the bracket III11, so that the detection and transportation module I3 is relatively located above the detection and transportation module II4. The sliced ​​pineapple fruits on the detection and transportation module I3 can automatically fall onto the detection and transportation module II4 when they are transported to the terminal discharge end, and the detection and transportation module II4 continues to carry out inspection and transportation.

[0073] In an optional embodiment, the detection and transportation module I3 and the detection and transportation module II4 both include motors and conveyor belts driven by the motors.

[0074] A flipping module 5 is provided between the inspection and transport module I3 and the inspection and transport module II4. As the sliced ​​pineapple fruit is transferred from the inspection and transport module I3 to the inspection and transport module II4, the flipping module 5 can flip the sliced ​​pineapple fruit over. This allows the sliced ​​pineapple fruit to be transported through the inspection and transport module I3 and the inspection and transport module II4 with two different upper surfaces.

[0075] See also Figure 4 As shown, the flip module 5 is disposed between the discharge end of the detection and transport module I3 and the feed end of the detection and transport module II4. The flip module 5 comprises a flip plate 501 and a flip frame 502. The flip frame 502 is fixedly disposed on the discharge end of the detection and transport module I3. One end of the flip plate 501 is rotatably disposed on the flip frame 502. The other end of the flip plate 501 extends obliquely downward to the outside of the discharge end of the detection and transport module I3 and is located above the feed end of the detection and transport module II4. The end of the flip plate 501 facing away from the flip frame 502 has a downwardly curved rotation extension 5011. When the sliced ​​pineapple fruit on the inspection and transportation module I3 is transported to the end and continues to move forward and is ready to fall downward to the inspection and transportation module II4, the sliced ​​pineapple fruit will contact the turning plate 501 and push the turning plate 501 upward during the movement. At the same time, the front end of the sliced ​​pineapple fruit is clamped by the rotating extension part 5011 of the turning plate 501 during the process of moving forward and falling downward, causing the sliced ​​pineapple fruit to flip 180° when it falls and hits the rotating extension part 5011 of the turning plate 501, thus completing the turning over of the sliced ​​pineapple fruit.

[0076] Correspondingly, the visual inspection module 6 includes a visual inspection module I61 and a visual inspection module II62. Specifically, the visual inspection module I61 and the visual inspection module II62 are respectively arranged above the inspection and transportation module I3 and the inspection and transportation module II4, and can respectively perform real-time visual inspection on the sliced ​​pineapple fruits being transported online on the inspection and transportation module I3 and the inspection and transportation module II4. Moreover, the visual inspection module I61 and the visual inspection module II62 are both connected to the intelligent grading system module 7. In this way, the visual inspection module I61 and the visual inspection module II62, combined with the conveying mode of the inspection and transportation module I3 and the inspection and transportation module II4, can realize visual inspection of the front and back sides of the sliced ​​pineapple fruits, and transmit the inspection results to the intelligent grading system module 7 in real time.

[0077] In an optional embodiment, both visual inspection module I 61 and visual inspection module II 62 include a photo box 601. Photo box 601 is a frame structure with a bottom that can accommodate the conveyor line of the transport module. The photo boxes 601 of visual inspection module I 61 and visual inspection module II 62 are fixedly mounted in the middle of the conveyor line of inspection and transport module I 3 and inspection and transport module II 4, respectively. A camera 602 is provided on the top of photo box 601, with the lens of camera 602 facing downward toward the conveyor line of the transport module. A ring light source 603 is provided on the top of photo box 601 and around camera 602, illuminating downward. Camera 602 is connected to intelligent rating system module 7 via a cable. During visual inspection, camera 602 takes photos of sliced ​​pineapple fruits being transported on the conveyor line of the transport module, capturing information about the upper surface of the sliced ​​pineapple fruits. The photographed information can be transmitted to intelligent rating system module 7 in real time.

[0078] Optionally, the intelligent rating system module 7 includes a rating algorithm for black heart disease detection results and a rating scale for automatic comparison. After the visual inspection module 6 transmits the visual inspection information from the front and back of the sliced ​​pineapple fruit to the intelligent rating system module 7, the intelligent rating system module 7 calculates the inspection information according to the rating algorithm and automatically compares it to the set rating scale to determine the black heart disease grade. Furthermore, in an optional embodiment, the intelligent rating system module 7 includes an electronic calculator such as a computer, equipped with a human-machine interface, and the black heart disease grade automatically rated by the intelligent rating system module 7 is directly displayed via the human-machine interface.

[0079] In a preferred embodiment, the black heart disease detection result rating algorithm entered into the intelligent rating system module 7 may include:

[0080] Extract the total area of ​​the front flesh and the area of ​​the black heart lesion in the front flesh of the sliced ​​pineapple fruit detected by the visual inspection module I, record the total area of ​​the front flesh as A, record the area of ​​the black heart lesion in the front flesh as A1, and record the color change of the black heart lesion in the front flesh;

[0081] Extract the total area of ​​the back flesh and the area of ​​the black heart lesions in the back flesh of the sliced ​​pineapple fruit detected by the visual inspection module II, record the total area of ​​the back flesh as B, record the area of ​​the black heart lesions in the back flesh as B1, and record the color change of the black heart lesions in the back flesh;

[0082] And calculate the total area of ​​black heart spots in the sliced ​​flesh of a single pineapple A1 总 、B1 总 and the total area of ​​sliced ​​pulp A 总 、B 总 , take A1 总 / A 总 and B1总 / B 总 The maximum percentage of the two is combined with the recorded discoloration of the black heart spots in the corresponding flesh and compared with the set rating level.

[0083] In a preferred embodiment, the rating levels entered into the intelligent rating system module 7 for automatic comparison are 0 to 5, including:

[0084] Level 0: no lesions;

[0085] Level 1: Lesions begin to form without discoloration, occupying less than 10% of the total area of ​​the cut pineapple flesh;

[0086] Level 2: The lesions are not discolored and occupy 11% to 20% of the total area of ​​the cut pineapple flesh;

[0087] Level 3: The lesions are initially brown and cover 21% to 30% of the total area of ​​the sliced ​​pineapple flesh.

[0088] Level 4: The lesions are brown to dark brown, covering 31% to 50% of the total area of ​​the cut pineapple flesh;

[0089] Level 5: The lesions are dark brown and occupy more than 50% of the total area of ​​the sliced ​​flesh of the entire pineapple.

[0091] The pineapple black heart disease rating method of the embodiment of the present invention adopts the rating equipment of embodiment 1 for rating, and the specific process is shown in Figure 5 As shown, the following steps are included:

[0092] S1, startup equipment, pineapple fruit leaf pre-cutting module 1 carries out pineapple fruit leaf pre-cutting to the pineapple fruit with fruit leaf, and pineapple fruit leaf is separated from fruit; Pineapple fruit leaf is collected by discharging chute 103 dischargings, and pineapple fruit is transported to pineapple slicing module 2 by feeding transport module 8 and slices;

[0093] S2, pineapple slicing module 2 pairs of feeding and transporting modules 8 conveyed pineapple fruit longitudinally sliced, i.e. the pineapple fruit after pre-cutting the fruit leaves is cut into multiple pieces of petals along the major diameter direction, and the slice thickness is 5-10mm;

[0094] After slicing, the sliced ​​pineapple fruit falls directly onto the inspection and transportation module I3 for on-line inspection and transportation, and the side of the sliced ​​pineapple fruit facing upward on the conveying line of the inspection and transportation module I3 is the front side, and the other side is the back side;

[0095] S3, the visual inspection module I61 performs a visual inspection on the front of the sliced ​​pineapple fruit transported online on the inspection and transportation module I3, and transmits the inspection information to the intelligent grading system module 7 in real time; in the intelligent grading system module 7, the intelligent grading system module 7 extracts the total area of ​​the front flesh of the sliced ​​pineapple fruit and the area of ​​the black heart lesion in the front flesh according to the algorithm, records the total area of ​​the front flesh as A, records the area of ​​the black heart lesion in the front flesh as A1, and records the color change of the black heart lesion in the front flesh;

[0096] S4, sliced ​​pineapple fruit are transported to the end of detection and transport module I 3, and fall on the detection and transport module II 4. During the falling process, the flip module 5 completes the 180 ° flipping of the sliced ​​pineapple fruit, so that the sliced ​​pineapple fruit is transported on the detection and transport module II 4 with the reverse side facing up;

[0097] S5, the visual inspection module II 62 performs a visual inspection on the back of the sliced ​​pineapple fruit transported online on the inspection and transportation module II 4, and transmits the inspection information to the intelligent grading system module 7 in real time; in the intelligent grading system module 7, the intelligent grading system module 7 extracts the total area of ​​the back flesh of the sliced ​​pineapple fruit and the area of ​​the black heart lesion in the back flesh according to the algorithm, records the total area of ​​the back flesh as B, records the area of ​​the black heart lesion in the back flesh as B1, and records the color change of the black heart lesion in the back flesh;

[0098] S6, completing online visual inspection of the front and back sides of multiple slices of pineapple fruit cut from a single pineapple;

[0099] S7, in the intelligent rating system module 7, the intelligent rating system module 7 calculates the total area A1 of the black heart spot area of ​​the sliced ​​flesh of a single pineapple according to the algorithm. 总 、B1 总 and the total area of ​​sliced ​​pulp A 总 、B 总 , take A1 总 / A 总 and B1 总 / B 总 The maximum percentage of the two, combined with the recorded discoloration of the black heart spots in the corresponding flesh, is compared with the set rating level;

[0100] In a specific optional embodiment, the set rating level is 0 to 5, including:

[0101] Level 0: no lesions;

[0102] Level 1: Lesions begin to form without discoloration, occupying less than 10% of the total area of ​​the cut pineapple flesh;

[0103] Level 2: The lesions are not discolored and occupy 11% to 20% of the total area of ​​the cut pineapple flesh;

[0104] Level 3: The lesions are initially brown and cover 21% to 30% of the total area of ​​the sliced ​​pineapple flesh.

[0105] Level 4: The lesions are brown to dark brown, covering 31% to 50% of the total area of ​​the cut pineapple flesh;

[0106] Level 5: The lesions are dark brown and cover more than 50% of the total area of ​​the sliced ​​pineapple flesh;

[0107] The obtained grade result is used as the black heart disease grade of the pineapple, and the black heart disease grade is directly displayed on the human-computer interface;

[0108] S8. The sliced ​​pineapple fruits are unloaded at the end of the detection and transportation module II and collected.

[0109] The pineapple blackheart disease rating method of this embodiment can quickly and efficiently obtain accurate rating results, and more accurately, effectively, and comprehensively judge and rate the severity of pineapple blackheart disease spots, thereby better providing accurate theoretical and practical information for researchers of pineapple blackheart disease physiological diseases and non-destructive testing researchers.

[0110] In a specific embodiment, as shown in Table 1, the rating results of 100 pineapples of the same sample were obtained by using the traditional pineapple black heart disease rating method and the pineapple black heart disease rating method of this embodiment.

[0111] Table 1 Rating results of pineapple black heart disease by traditional method and method of this embodiment

[0112]

[0113] From the results in Table 1, it can be seen that among the 100 pineapples in the same sample, the number of black hearts in the pineapple black heart disease was 32 when the traditional method was used to determine the pineapple black heart disease, which is only about half of the number determined by the method of this embodiment. Its accuracy is about 50%. The accuracy of the pineapple black heart disease rating is much lower than that of the method of this embodiment.

[0114] In addition, during the experiment, the same pineapple sample was cut and observed according to the traditional method and cut and observed multiple times according to the method of this embodiment, and the black heart area was compared. Figure 6 As shown, the pineapple sample was cut into two halves longitudinally. According to the results of the cutting, no black heart disease was found, and the traditional method did not record it as black heart disease. However, according to the method of this embodiment, multiple cuts were made (cut into 12 slices, the slice thickness was 10 mm), and the front and back of the sliced ​​pineapple fruit were observed as shown in FIG. Figure 7a and Figure 7bAs shown, multiple slicing can reveal the black heart portion that is unforeseeable with traditional methods. It can be seen that the pineapple scab grading method of this embodiment helps improve the accuracy of pineapple black heart grading.
