Description

Technical Field

[0001] This utility model relates to an integrated machine for sorting spherical fruits and identifying blemishes. Background Technology

[0002] Traditional sorting equipment, limited by its technical principles and functional design, can only sort by size and cannot identify rotten spots or bruises. These devices typically rely on mechanical structures and simple size sensors, using fixed-size screening channels to classify fruits by size, performing only the most basic sorting task. While the fruits piled on the production line may appear uniform in size after size sorting, hidden problems exist. Detecting rotten spots and bruises is crucial for fruit quality control; these defects not only affect the appearance of the fruit but can also accelerate spoilage and reduce its commercial value. Existing sorting equipment cannot identify rotten spots and bruises, requiring manual removal of defective fruits after size sorting. To ensure product sorting and quality, manual sorting requires long hours of continuous work, potentially leading to missed inspections and inconsistent sorting quality. Therefore, relying on traditional sorting equipment cannot meet the demands of modern fruit sorting for precision and efficiency.

[0003] In addition, the sorting equipment cannot control the speed at which the fruit falls during the sorting operation, which can also cause damage to the fruits and vegetables. Summary of the Invention

[0019] The side of the screening drum with the blocking grid faces the direction in which the roller screening mechanism is installed.

[0020] Furthermore, the bottom of the machine body feeding trough gradually narrows from one end to the other.

[0030] Furthermore, the number of the spacers (1D4) is 6-8. Beneficial effects

[0031] 1. This utility model employs a visual recognition mechanism to assist in the fruit sorting process. Although the process of identifying and screening blemishes on the fruit surface using a visual recognition mechanism can be achieved using existing deep learning algorithms for image recognition, this utility model, in addition to relying on the visual recognition mechanism to achieve blemish identification, is primarily a specific component capable of sorting the identified blemished fruits. It is a sorting device that realizes the blemish identification results. Therefore, this utility model overcomes the shortcomings of traditional sorting equipment that only sorts fruits based on size, ensuring the high quality of the sorted fruits.

[0032] 2. In the sorting process, this utility model also relies on the partition plates and blocking grids added to the screening roller to slow down the falling speed of spherical fruits and vegetables during the screening process, reduce the damage to fruits and vegetables caused during the screening process, and prevent more mature fruits from being injured during the fall, thus avoiding unnecessary losses.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Specific implementation method one:

[0051] This embodiment provides an integrated machine for sorting spherical fruits and identifying blemishes, such as... Figure 1 , Figure 2 As shown, its components include a roller sorting mechanism 1, a vision recognition mechanism 2, a roller screening mechanism 3, and a storage box 4.

[0052] The roller sorting mechanism 1 is located at the front end of the entire device. Several sets of roller screening mechanisms 3 are arranged behind the roller sorting mechanism 1. A storage box 4 is arranged on the left side and at the end of each roller screening mechanism 3. A set of visual recognition mechanism 2 is arranged on the right side of each set of roller screening mechanisms 3. A storage box 4 is also arranged on the left side of the roller sorting mechanism 1.

[0053] like Figure 3 , 4 As shown, the roller sorting mechanism 1 also includes a body support 1A, a body receiving groove 1B, a body feeding groove 1C, and a body discharge groove 1E. The body support 1A is the load-bearing and supporting structure of the roller sorting mechanism 1. The body support 1A is groove-shaped. Each side wall of the body support 1A includes an upper side wall and a lower side wall. The lower side walls of the two side walls are parallel and perpendicular to the bottom surface of the groove. The upper side walls of the two side walls are parallel to each other and the included angle between them and the bottom surface of the groove is 3° to 20°. A row of roller mounting holes 1A1 is provided on the upper side wall of each side wall of the body support 1A. The positions of the roller mounting holes 1A1 between the two upper side walls correspond to each other. A body discharge port 1A2 is provided below each roller mounting hole 1A1 on the side of the body support 1A facing the roller screening mechanism 3.

[0054] A set of machine body receiving grooves 1B is installed between the two side walls of the machine body support 1A. The installation position of the port of each machine body receiving groove 1B corresponds to the machine body discharge port 1A2. The plane of the side wall of the machine body receiving groove 1B is perpendicular to the plane of the upper side wall of the machine body support 1A. The angle between the plane of the bottom surface of the machine body receiving groove 1B and the horizontal plane is between 3° and 20°, and it is in a state of being higher in the front and lower in the back. The width of the machine body discharge port 1A2 is the same as that of the machine body receiving groove 1B.

[0055] Each roller mounting hole 1A1 is equipped with a bearing, and a set of screening rollers 1D are mounted in the roller mounting holes 1A1 between the upper side walls of the groove walls on both sides of the machine body support 1A through the bearings. Specific Implementation Method Two:

[0057] This embodiment of the spherical fruit sorting and blemish recognition integrated machine differs from specific embodiment one in that, for example... Figure 5 , Figure 6As shown, the screening roller 1D includes a roller shaft 1D1, two roller supports 1D2, and a roller screen 1D3; the two roller supports 1D2 are fixedly installed at both ends inside the roller screen 1D3, and the roller shaft 1D1 passes through the middle of the two roller supports 1D2 in sequence.

[0058] The drum screen 1D3 has a hollow cylindrical structure. The diameter of the drum screen 1D3 is the same as the width of the receiving groove 1B of the machine body, and the length of the drum screen 1D3 is the same as the length of the receiving groove 1B of the machine body. The surface of the drum screen 1D3 has a set of screen holes 1D3a in a dot matrix pattern. The screen holes 1D3a are circular through holes. The diameter of the screen holes 1D3a is 20-100mm.

[0059] The roller support 1D2 includes a plate-shaped circular structure in the middle part, with a circular hole in the center of the plate-shaped circular structure, and a set of supports arranged radially around the plate-shaped circular structure.

[0060] The roller shaft 1D1 is a hollow shaft. The roller shaft 1D1 passes through the circular hole in the center of the roller support 1D2 and is fixed inside the circular hole.

[0061] During the screening of spherical fruits and vegetables, some of the more mature fruits may be damaged during the fall, resulting in unnecessary losses. Therefore, appropriate structures can be added to the screening drum to slow down the falling speed of the spherical fruits and vegetables and reduce the damage to the fruits and vegetables during the screening process.

[0062] And, as Figure 11-13 As shown, on the side of the shaft of the drum shaft 1D1 inside the drum screen 1D3, a set of partition plates 1D4 are evenly distributed around the drum shaft 1D1. Several partition plates 1D4 divide the space inside the drum screen 1D3 into multiple independent areas; among them, the partition plate 1D4 is a rectangular sheet structure.

[0063] like Figure 14 As shown, a blocking grid 1D5 is rotatably mounted on one end of the roller shaft 1D1 outside the roller support 1D2. The blocking grid 1D5 includes a grid plate 1D5a, a grid hub 1D5b, a grid counterweight block 1D5c, and a grid counterweight rod 1D5d.

[0064] The grid hub 1D5b is fixedly installed in the middle part of the grid plate 1D5a. The grid counterweight rod 1D5d is fixedly connected to the bottom of the grid plate 1D5a. The grid counterweight block 1D5c is installed on the grid counterweight rod 1D5d. The grid counterweight block 1D5c is located at the bottom of the blocking grid 1D5.

[0065] The grating plate 1D5a has an arc-shaped layered structure. A set of through holes are arranged on the panel of the grating plate 1D5a. The long sides of the through holes extend to the arc edge and the chord edge respectively. The grating hub 1D5b is located at the center of the circle in which the grating plate 1D5a is located. The grating hub 1D5b is equipped with a rolling bearing. The rolling bearing is used to mount the entire blocking grating 1D5 onto the roller shaft 1D1, so that the blocking grating 1D5 can rotate freely around the roller shaft 1D1 through the grating hub 1D5b.

[0066] The counterweight 1D5c is made of lead, and its mass exceeds the sum of the masses of the grid plate 1D5a and the grid hub 1D5b. This ensures that no matter how the screening roller 1D rotates around the roller shaft 1D1, the counterweight 1D5c will always be located at the bottom of the screening roller 1D, close to the machine body receiving groove 1B, under the action of gravity, while the grid plate 1D5a is located in the upper middle part of the screening roller 1D, at a position relatively far away from the machine body receiving groove 1B.

[0067] When installing the screening roller 1D with the blocking grid 1D5, the side of the screening roller 1D with the blocking grid 1D5 should face the direction of the installation roller screening mechanism 3. Specific implementation method three:

[0069] This embodiment of the integrated machine for sorting spherical fruits and identifying blemishes differs from specific embodiments one or two in that the bottom of the machine body feeding trough 1C gradually narrows from one end to the other. The narrow end of the machine body feeding trough 1C is fixedly installed on the feeding end of the machine body support 1A. The angle between the plane where the bottom of the machine body feeding trough 1C is located and the horizontal plane or the bottom of the machine body support 1A is 3° to 30°, and the wide end of the machine body feeding trough 1C is higher than the narrow end of the machine body feeding trough 1C. The bottom of the machine body feeding trough 1C is a thin plate structure, and the width of the narrow end of the machine body feeding trough 1C is the same as the length of the drum screen 1D3.

[0070] The bottom of the machine body outlet trough 1E gradually narrows from one end to the other. The wide end of the machine body outlet trough 1E is fixedly installed at the discharge end of the machine body support 1A. The angle between the plane where the bottom of the machine body outlet trough 1E is located and the horizontal plane or the bottom of the machine body support 1A is 3° to 30°, and the wide end of the machine body outlet trough 1E is higher than the narrow end of the machine body outlet trough 1E. The bottom of the machine body outlet trough 1E is a thin plate structure, and the width of the wide end of the machine body outlet trough 1E is the same as the length of the drum screen 1D3. The storage box 4 is located below the machine body outlet trough 1E.

[0071] The roller shaft 1D1 is inserted into a pair of corresponding roller mounting holes 1A1 via bearings, thereby enabling the screening roller 1D to be mounted on the machine body support 1A; the interval between two adjacent sets of screening rollers 1D is 5 to 15 mm; the machine body receiving groove 1B is located below the screening roller 1D. Specific implementation method four:

[0073] This embodiment of the spherical fruit sorting and blemish recognition integrated machine differs from specific embodiment three in that... Figure 7 As shown, the visual recognition mechanism 2 includes a visual support 2A, a visual camera 2B, and a mounting base 2C;

[0074] The visual support 2A is L-shaped, and the bottom of the visual support 2A is mounted on the fixed base 2C. The visual camera 2B is mounted on the crossbar at the top of the visual support 2A. The visual camera 2B includes a camera and a lens. Specific implementation method five:

[0076] This embodiment of the spherical fruit sorting and blemish recognition integrated machine differs from specific embodiments one, two, or four in that, for example... Figure 8 , Figure 9 As shown, the roller screening mechanism 3 includes a gathering groove 3A, an upper guide groove 3B, a screening groove 3C, a screening cylinder 3D, and a lower guide groove 3E connected in sequence from end to end.

[0077] The plane containing the bottom of the gathering trough 3A, the upper guide trough 3B, and the lower guide trough 3E forms an angle of 3° to 30° with the horizontal direction. The horizontal height of the wide end of the gathering trough 3A is higher than the horizontal height of the discharge end of the lower guide trough 3E.

[0078] The bottom of the gathering trough 3A gradually narrows from one end to the other. The wide end of the gathering trough 3A is fixedly installed at the machine body discharge port 1A2 and connected to the machine body receiving trough 1B. The width of the top of the gathering trough 3A is the same as that of the machine body receiving trough 1B. The narrow end of the gathering trough 3A is connected to the upper guide trough 3B. A storage box 4 is placed below the lower guide trough 3E.

[0079] The angle between the plane containing the bottom of the upper guide groove 3B and the horizontal plane is 3-30°, meaning that one end of the upper guide groove 3B is higher than the other end, and the bottom of the groove is inclined.

[0080] like Figure 9 , Figure 10 As shown, a cylinder working hole 3C1 is provided on the right side wall of the screening tank 3C, and a screening guide groove 3C2 is provided on the left side wall of the screening tank 3C, corresponding to the position of the cylinder working hole 3C1. The cylinder working hole 3C1 and the screening guide groove 3C2 are symmetrical in spatial position. The screening cylinder 3D is fixedly installed on the outside of the cylinder working hole 3C1, and the extended movable part of the screening cylinder 3D can extend into the screening tank 3C through the cylinder working hole 3C1. The angle between the plane where the bottom of the screening guide groove 3C2 is located and the plane where the bottom of the screening tank 3C is located is 3-30°, that is, the bottom of the screening guide groove 3C2 is inclined. A storage box 4 is placed below the outlet end of the screening guide groove 3C2.

[0081] The visual camera 2B of the visual recognition mechanism 2 is located above the upper guide groove 3B. Specific implementation method six:

[0083] The spherical fruit sorting and blemish identification integrated machine of this embodiment differs from Specific Embodiment Five in that the number of the spacers 1D4 is 6-8.

[0084] Working principle:

[0085] Before use, measure the diameter of this batch of spherical fruits 3F. Select the drum screen 1D3 according to the diameter of the spherical fruits 3F. The diameter of the screen hole 1D3a on the drum screen 1D3 on the left side near the machine body feed chute 1C is the smallest, and the diameter of the screen hole 1D3a on the drum screen 1D3 on the right side near the machine body discharge chute 1E is the largest. The diameter of the screen hole 1D3a on two adjacent drum screens 1D3 differs by 3-5mm.

[0086] In use, the motor drives each screening roller 1D to rotate from left to right, and the spherical fruits 3F to be sorted are poured into the feed trough 1C of the machine body; the spherical fruits 3F will be picked up by each screening roller 1D from left to right and move to the right.

[0087] When the diameter of the spherical fruit 3F is smaller than the diameter of the sieve hole 1D3a on the current screening roller 1D, the spherical fruit 3F will fall through the sieve hole 1D3a into the machine receiving groove 1B below. Since the machine receiving groove 1B has a certain inclination angle, the spherical fruit 3F will continue to roll downwards, enter the gathering groove 3A, and then enter the upper guide groove 3B. The upper guide groove 3B can only allow a single row of spherical fruits 3F to pass through. The visual recognition mechanism 2 located above the upper guide groove 3B will take pictures of the rolling spherical fruit 3F to obtain a surface image of the spherical fruit 3F and transmit it to the analysis and control system so as to analyze whether the surface of the spherical fruit 3F that has rolled to this point has obvious blemishes.

[0088] like Figure 9 As shown, when the surface blemishes of the current spherical fruit 3F are detected to be relatively severe, the screening cylinder 3D will extend and push the screening cylinder 3D into the screening guide groove 3C2, and then fall into the storage box 4 below through the screening guide groove 3C2.

[0089] When the test is passed, the screening cylinder 3D will not extend, and the spherical fruit 3F will continue to roll downwards and fall into the corresponding storage box 4 through the lower guide groove 3E, thereby obtaining the spherical fruit 3F of the required size.

[0090] Finally, any spherical fruit 3F that exceeds the diameter of the sieve hole 1D3a on the rightmost set of screening rollers 1D will fall into the corresponding storage box 4 through the machine's discharge slot 1E, thus completing the sorting and screening of this batch of spherical fruit 3F.

[0091] Each set of screening rollers 1D must be equipped with a set of roller screening mechanism 3 and a set of visual recognition mechanism 2, as well as a storage box 4 to receive spherical fruits 3F.

[0092] In this specific embodiment, there are 3 sets of screening rollers 1D, and 3 sets of corresponding roller screening mechanism 3 and visual recognition mechanism 2. In use, the number of screening rollers 1D, roller screening mechanism 3 and visual recognition mechanism 2 can be increased or decreased according to the actual situation.

[0093] In addition, such as Figure 15 , Figure 16 As shown, during the screening process, spherical fruits and vegetables roll to the upper area of ​​the screening drum 1D. After the spherical fruits and vegetables fall into the interior of the screening drum 1D through the upper sieve hole 1D3a, they will not fall directly to the bottom of the inner wall of the drum screen 1D3 under the action of gravity. Instead, they will fall into the area separated by the two partition plates 1D4 corresponding to the sieve hole 1D3a they passed through. Because the screening drum 1D has a certain angle when it is installed on the machine support 1A, the height of the side of the screening drum 1D near the roller screening mechanism 3 with the blocking grid 1D5 is lower than that of the machine support 1A. On the other side, under the influence of gravity, spherical fruits and vegetables will roll towards the blocking grid 1D5 within the area separated by the two partition plates 1D4, and stop due to the obstruction of the grid plate 1D5a. However, as the screening roller 1D rotates, the partition area where the spherical fruits and vegetables are located will rotate to a position close to the receiving groove 1B of the machine body. At this time, the spherical fruits and vegetables in this partition area will no longer be obstructed by the grid plate 1D5a, and will roll out of the screening roller 1D from the area of ​​the grid counterweight block 1D5c at the bottom of the blocking grid 1D5, falling into the roller screening mechanism 3 for subsequent screening. By setting the blocking grid 1D5, the descent speed of the spherical fruits and vegetables is slowed down during the screening process, reducing the damage to the fruits and vegetables caused during the screening process, and preventing more mature fruits from being injured during the fall, causing unnecessary losses.

[0094] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
