Description

Technical Field

[0001] This invention belongs to the field of food processing technology, and in particular relates to an automated device for sorting and quality monitoring of mulberries. Background Technology

[0002] Mulberries are the fruit of the mulberry tree, a perennial woody plant belonging to the genus *Morus* of the family Moraceae. They are oval-shaped, 1-3 cm long, with an uneven surface. When unripe, they are green, gradually turning white and red, and finally purplish-red or purplish-black when ripe, with a sweet and sour taste. Mulberries contain various functional components, such as rutin, anthocyanins, and resveratrol, which have good anti-cancer, anti-aging, anti-ulcer, and antiviral effects. Mulberries are rich in nutrients, but their shelf life is very short. After harvesting, they need to be eaten or processed into other foods as soon as possible. For low-yield mulberry orchards, manual harvesting is usually used. However, for large-yield orchards, manual harvesting is costly and inefficient, so harvesting machines are often used. After harvesting, mulberries must be sorted according to their size and quality for different uses. However, commercially available sorting and quality monitoring devices still have the following drawbacks in practical use:

[0003] 1. Before sorting, the mulberries are freshly picked, so there will be some water droplets or dew on their surface. If they are not treated, the friction between the mulberries will increase, causing the skin to break and reducing the quality of sorting. Secondly, if the mulberries are mechanically picked, they usually contain large pieces of mulberry leaves and other objects, which need to be processed before sorting.

[0004] 2. Currently, mulberries are sorted and matched according to their size. However, mulberries have a special shape and structure, mostly cylindrical, and the usual mesh sorting cannot achieve the desired effect, resulting in low sorting efficiency.

[0005] 3. After sorting, mulberries need further processing due to strict quality control. This is because sorted mulberries need to be washed or processed in other ways. The most important step is to remove the mulberry stems, as the stems will affect fermentation. The stems are inedible, and if fermented with the stems, they will turn sour, especially if the mulberries are used to make fruit wine, jam, or similar products.

[0006] Therefore, existing mulberry sorting and quality monitoring devices cannot meet the needs of actual use, so there is an urgent need for improved technologies to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide an automated device for mulberry sorting and quality monitoring. By setting up a pretreatment structure, it solves the problem of lacking surface drying and impurity removal functions before mulberry sorting; by setting up a first sorting plate and a second sorting plate, it solves the problem that the special shape of mulberries makes it impossible for ordinary sorting structures to sort them quickly; by setting up a first processing structure, a second processing structure and a standing plate, it solves the problem that the fruit stems of mulberries cannot be removed quickly and automatically after sorting.

[0008] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0009] This invention relates to an automated device for mulberry sorting and quality monitoring, comprising a pretreatment structure, a first sorting disc, a second sorting disc, a first processing structure, a second processing structure, and a vertical plate. The pretreatment structure includes two fans, each with an air outlet pipe fixed to its outlet end, and a through-type air guide hood provided on the circumferential side of the front part of the air outlet pipe. The fans generate air that is discharged through the air outlet pipe and delivered to the air guide hood, blowing upward to dry the moisture on the surface of the mulberries, reducing the friction of the mulberries, and simultaneously blowing away mulberry leaves and other debris inside the mulberries.

[0010] First side baffles are fixed on both sides of the upper end of the first sorting plate. The first sorting plate inside the two first side baffles is provided with evenly distributed first sorting grooves. The first sorting grooves are slightly smaller than normal large mulberries, which can prevent large mulberries from falling and sort out large mulberries. The first side baffles prevent mulberries from falling during the sorting process.

[0011] A material discharge channel is fixed on the first sorting plate on one side of the first side baffle, and a sorting hopper is fixed through the upper end of the material discharge channel; the sorting hopper collects the mulberries in the pretreatment structure and outputs them to the first sorting plate;

[0012] The upper end of the second sorting disc is fixed with two side baffles, and the second sorting disc between the two side baffles is provided with evenly distributed second sorting grooves; the second sorting grooves are slightly smaller than the first sorting grooves and slightly smaller than normal mulberry grains, to further sort the normal mulberry grains; the second side baffles also prevent mulberries from falling.

[0013] A collection box is provided below the second sorting tray; the collection box is used to collect small mulberry particles that fall off the second sorting tray.

[0014] A material guiding structure is provided on one side of the first and second sorting discs; the material guiding structure is used to guide the sorted mulberries out.

[0015] The material guiding structure is provided with a first processing structure and a second processing structure on one side.

[0016] Both the first processing structure and the second processing structure are fixed with upright plates. Support rods are fixed at both ends of the bottom of the upright plates. A first plastic strip is fixed at the bottom of the upright plate between the two support rods. A second plastic strip is fixed between the two support rods below the first plastic strip.

[0017] The first and second processing structures work together with the uprights to arrange the mulberries neatly and remove the stems.

[0018] Furthermore, the pretreatment structure also includes two first frames and a first conveyor belt. The top of the inner side of the two first frames is rotatably connected to a first rotating shaft, and the outer side of the two first rotating shafts is covered with a first conveyor belt. The outer side of the first conveyor belt is symmetrically fixed with first baffles, and the first conveyor belt inside the two first baffles is evenly provided with through mesh holes. The first baffles prevent mulberries from falling during transport.

[0019] Furthermore, the air guide hood on the air outlet pipe is obliquely arranged and communicates with the air outlet pipe, and the air guide hood is located below the first conveyor belt and on the same horizontal plane as the first rotating shaft; the air guide hood outputs the airflow generated by the fan obliquely upward, blows the surface moisture of the mulberries on the first conveyor belt to make them evenly distributed, and blows away mulberry leaves and other debris.

[0020] Furthermore, the sorting hopper is located diagonally below the pretreatment structure. A discharge plate is movably connected inside the sorting hopper via a pin. One end of the discharge plate extends out of the sorting hopper, and the other end abuts against the inner wall of the sorting hopper. An opening is provided at the end of the discharge plate abutting against the inner wall of the sorting hopper. The sorting hopper gathers the mulberries in the pretreatment structure and conveys them through the discharge plate.

[0021] Furthermore, the bottom of the material feeding channel near the first sorting groove has an outlet, and a first base plate is fixed at one end of the first sorting disc near the material feeding channel. A first vibration motor is fixed above the first base plate. The vibration of the first vibration motor causes the first sorting disc to vibrate, so that the mulberries are quickly sorted on its surface through the first sorting groove.

[0022] Furthermore, a support column is fixed above the second sorting disc at one end of the two second side baffles. The upper end of the support column is fixed to the bottom end of the first sorting disc. A second base plate is fixed to the end of the second sorting disc near the support column. A second vibration motor is fixed to the upper end of the second base plate. The vibration of the second vibration motor causes the second sorting disc to vibrate, so that the mulberries are quickly further sorted on its surface through the second sorting groove.

[0023] Furthermore, the material guiding structure includes a first material guiding hopper and a second material guiding hopper, which are fixed between two supports. A material guiding groove is provided through one side wall of both the first and second material guiding hoppers. A first material guiding plate is fixed to the outside of the material guiding groove of the first material guiding hopper, and a second material guiding plate is fixed to the outside of the material guiding groove of the second material guiding hopper. The mulberries sorted on the first and second sorting plates are exported through the first and second material guiding plates.

[0024] Furthermore, the first guide hopper is located diagonally below the first sorting disc, the second guide hopper is located diagonally below the second sorting disc, the bottom of the first guide disc faces diagonally above the first processing structure, and the bottom of the second guide disc faces diagonally above the second processing structure.

[0025] Furthermore, the first processing structure includes two second frames and a second conveyor belt. The inner top of the two second frames is rotatably connected to a second rotating shaft. The outer circumferential surface of the two second rotating shafts is covered with a second conveyor belt. The outer surface of the second conveyor belt is symmetrically fixed with second baffles. The second conveyor belt between the two second baffles is evenly provided with first conical holes. Two support rods at the bottom of the upright plate are fixed to the middle of the two second frames. Through the operation of the second conveyor belt, in conjunction with the upright plate, the mulberries are vertically placed in the first conical holes in the second conveyor belt. When passing through the first plastic strip and the second plastic strip, the fruit stems of the mulberries are broken off and removed.

[0026] Furthermore, the second processing structure includes a third frame and a third conveyor belt. The inner top of the two third frames is rotatably connected to a third shaft. The outer circumferential surface of the two third shafts is covered with a third conveyor belt. The outer surface of the third conveyor belt is symmetrically fixed with third baffles. The third conveyor belt between the two third baffles is evenly provided with second conical holes. Another upright plate is fixed to the middle of the two third frames by two support rods at the bottom. Through the operation of the third conveyor belt, in conjunction with the upright plate, the mulberries are vertically placed in the second conical holes in the third conveyor belt. When passing through the first plastic strip and the second plastic strip, the fruit stems of the mulberries are broken off and removed.

[0027] The present invention has the following beneficial effects:

[0028] 1. This invention solves the problem of lack of surface drying and impurity removal functions before mulberry sorting by setting up a pre-treatment structure. After the mulberries are picked, they are placed on the first conveyor belt in the pre-treatment structure. The fan is started and blows air obliquely upward through the air guide hood to evenly spread the mulberries on the first conveyor belt and dry the water stains on the surface of the mulberries, reducing the friction between the mulberries in the future. At the same time, it blows away the mulberry leaves and other structures mixed in with the mulberries. In addition, the use of two fans makes the processing efficiency higher.

[0029] 2. This invention solves the problem that ordinary sorting structures cannot quickly sort mulberries due to their special shape by setting up a first sorting disc and a second sorting disc. By using the first and second sorting discs to sort mulberries, and setting up first and second sorting grooves similar in shape to mulberries, large mulberries can be quickly separated from normal-sized mulberries, improving work efficiency and avoiding the problem that commonly used sorting structures on the market cannot quickly sort mulberries.

[0030] 3. This invention solves the problem of the inability to quickly and automatically remove fruit stems after mulberry sorting by setting up a first processing structure, a second processing structure, and a vertical plate. The first and second processing structures, together with the vertical plate, process large mulberries and normal-sized mulberries. During operation, the mulberries are blocked by the first plastic strip and placed vertically in the first and second conical holes. When they pass through the first and second plastic strips again, the fruit stems on the mulberries are broken off, thereby quickly removing the fruit stems and facilitating subsequent mulberry processing.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] Example 1

[0043] Please see Figure 1-7 As shown, the present invention is an automated device for mulberry sorting and quality monitoring, including a pretreatment structure 1, a sorting hopper 2, a first sorting disc 3, a second sorting disc 4, a collection box 5, a material guiding structure 6, a first processing structure 7, a second processing structure 8, and a vertical plate 9.

[0044] Among them, such as Figure 1-3 As shown, the pretreatment structure 1 includes two fans 106. The air outlet end of the fan 106 is fixed with an air outlet pipe 107, and a through air guide hood 108 is provided on the peripheral side of the front part of the air outlet pipe 107. When the two fans 106 are working, they blow air out through the air outlet pipe 107 and cooperate with the air guide hood 108 to blow air obliquely upward.

[0045] The pretreatment structure 1 also includes two first frames 101 and a first conveyor belt 103. The top inner side of the two first frames 101 is rotatably connected to a first rotating shaft 102, and the outer side of the two first rotating shafts 102 is covered with the first conveyor belt 103. The outer side of the first conveyor belt 103 is symmetrically fixed with first baffles 104, and the first conveyor belt 103 inside the two first baffles 104 is evenly provided with through mesh holes 105. The two first frames 101 serve as support carriers, and the first conveyor belt 103 is arranged outside the two first rotating shafts 102 inside them. One of the first rotating shafts 102 is connected to an external drive structure to drive the first rotating shaft 102 to rotate, thereby making the first conveyor belt 103 run.

[0046] The air guide shroud 108 on the air outlet duct 107 is obliquely arranged and communicates with the air outlet duct 107. The air guide shroud 108 is located below the first conveyor belt 103 and is on the same horizontal plane as the first rotating shaft 102. During pre-processing, the picked mulberries are placed on the first conveyor belt 103. As the first conveyor belt 103 rotates, two fans 106 are started, and air is discharged obliquely upward through the air guide shroud 108, blowing directly onto the surface of the mulberries through the mesh 105, thus purifying the mulberries. The surface water stains are dried and evenly distributed on the first conveyor belt 103, while blowing away mulberry leaves and other impurities contained in the mulberries. Smaller impurities will fall through the mesh 105. The first conveyor belt 103 moves towards the sorting hopper 2, and the first baffle 104 prevents the mulberries from falling from the side. The first baffle 104 is a soft plastic structure that can move synchronously with the first conveyor belt 103, thereby completing the initial mulberry sorting and quality monitoring process.

[0047] Among them, such as Figure 1 , 4 As shown, first side baffles 301 are fixed on both sides of the upper end of the first sorting disk 3, and first sorting grooves 302 are evenly distributed through the first sorting disk 3 inside the two first side baffles 301.

[0048] A material discharge channel 303 is fixed on the first sorting plate 3 on one side of the first side baffle 301, and a sorting hopper 2 is fixed through the upper end of the material discharge channel 303.

[0049] The sorting hopper 2 is located diagonally below the pretreatment structure 1. Inside the sorting hopper 2, a discharge plate 202 is movably connected via a pin 201. One end of the discharge plate 202 extends out of the sorting hopper 2, and the other end abuts against the inner wall of the sorting hopper 2. An opening 203 is provided at the end of the discharge plate 202 that abuts against the inner wall of the sorting hopper 2.

[0050] After initial sorting in the pretreatment structure 1, the mulberries are caught by the discharge plate 202, roll downwards at an angle, and enter the sorting hopper 2. The mulberries are slowly introduced into the sorting hopper 2 through the opening 203 at the end of the discharge plate 202.

[0051] An outlet 306 is provided at the bottom of the material discharge channel 303 near the first sorting tank 302. A first substrate 304 is fixed at one end of the first sorting plate 3 near the material discharge channel 303. A first vibration motor 305 is fixed above the first substrate 304.

[0052] Mulberries inside the sorting hopper 2 fall through the discharge channel 303 and enter the first sorting disc 3 through the outlet 306. Since the first sorting disc 3 is set at an angle, the mulberries will slowly roll down on its surface and be sorted in conjunction with the first sorting groove 302. The first sorting groove 302 is slightly smaller than the size of large mulberries but slightly larger than the size of normal mulberries, so it can prevent large mulberries from falling and keep them on the first sorting disc 3 to roll down. The first side baffle 301 can prevent mulberries from sliding out from the side during the rolling process. At the same time, in conjunction with the vibration of the first vibration motor 305, the mulberries on the first sorting disc 3 roll down quickly for sorting. Mulberries smaller than the size of the first sorting groove 302 fall from it into the second sorting disc 4, while large mulberries are discharged from the end of the first sorting disc 3.

[0053] Among them, such as Figure 1 , 4 As shown, the two sides of the upper end of the second sorting disk 4 are fixed with second side baffles 401, and the second sorting disk 4 between the two second side baffles 401 is provided with evenly distributed second sorting grooves 402.

[0054] A support column 403 is fixed above the second sorting disk 4 at one end of the two second side baffles 401. The upper end of the support column 403 is fixed to the bottom end of the first sorting disk 3. A second base plate 404 is fixed at one end of the second sorting disk 4 near the support column 403. A second vibration motor 405 is fixed at the upper end of the second base plate 404.

[0055] After being sorted on the first sorting plate 3, the mulberries fall directly onto the second sorting plate 4. The second sorting plate 4 is connected to the first sorting plate 3 via a support column 403. The second sorting plate 4 is also sorted via a second sorting groove 402. Similarly, the size of the second sorting groove 402 is smaller than that of normal-sized mulberries, which can prevent normal-sized mulberries from passing through and trap them on the second sorting plate 4. In conjunction with the vibration of the second vibration motor 405 on the second base plate 404, the sorting is carried out quickly. The trapped normal-sized mulberries are discharged from the end of the second sorting plate 4, while small mulberries fall from the second sorting groove 402 during the rolling process. At the same time, the second side baffle 401 can prevent the mulberries from sliding off the side of the second sorting plate 4 during the rolling process.

[0056] Below the second sorting plate 4 is a collection box 5; the collection box 5 is used to collect small mulberries that fall from the second sorting plate 4. The small mulberries are not aesthetically pleasing and have poor appearance, and are used for further processing, such as juicing, winemaking, making jam, etc.

[0057] At this point, the mulberries are sorted by size, completing the second step of the mulberry sorting machine's quality monitoring, which involves classifying them according to their size and quality.

[0058] Among them, such as Figure 1 , 5 As shown, a material guiding structure 6 is provided on one side of the first sorting disc 3 and the second sorting disc 4;

[0059] The material guiding structure 6 includes a first material guiding hopper 601 and a second material guiding hopper 602. The first material guiding hopper 601 and the second material guiding hopper 602 are fixed between two supports 603. A material guiding groove 606 is provided through one side wall of both the first material guiding hopper 601 and the second material guiding hopper 602. A first material guiding plate 604 is fixed to the outside of the material guiding groove 606 of the first material guiding hopper 601, and a second material guiding plate 605 is fixed to the outside of the material guiding groove 606 of the second material guiding hopper 602.

[0060] The feeding structure 6 is used to guide the mulberries sorted by the first sorting disc 3 and the second sorting disc 4 to the next stage of processing.

[0061] The first guide hopper 601 is located diagonally below the first sorting disc 3, the second guide hopper 602 is located diagonally below the second sorting disc 4, the bottom of the first guide disc 604 faces diagonally above the first processing structure 7, and the bottom of the second guide disc 605 faces diagonally above the second processing structure 8.

[0062] A first processing structure 7 and a second processing structure 8 are provided on one side of the material guiding structure 6;

[0063] The first guide hopper 601 and the second guide hopper 602 are both fixedly placed by the bracket 603, located on one side of the first sorting plate 3 and the second sorting plate 4. The first guide hopper 601 catches the large mulberries output from the end of the first sorting plate 3, and the second guide hopper 602 catches the normal-sized mulberries from the end of the second sorting plate 4. The first guide hopper 601 and the second guide hopper 602 both guide the mulberries out through the guide trough 606. The inner bottom surface of the first guide hopper 601 and the second guide hopper 602 is an inclined surface, and the mulberries collected in them will automatically roll in the direction of the guide trough 606. The first guide hopper 601 guides the large mulberries to the first processing structure 7 through the first guide plate 604, and the second guide hopper 602 guides the normal-sized mulberries to the second processing structure 8, thus completing the entire material transfer process.

[0064] Among them, such as Figure 1 , 6As shown in Figures 7 and 8, a vertical plate 9 is fixed on both the first processing structure 7 and the second processing structure 8. Support rods 901 are fixed at both ends of the bottom of the vertical plate 9. A first plastic strip 902 is fixed at the bottom of the vertical plate 9 between the two support rods 901. A second plastic strip 903 is fixed between the two support rods 901 below the first plastic strip 902.

[0065] The first processing structure 7 includes two second frames 701 and a second conveyor belt 703. The inner top of the two second frames 701 is rotatably connected to a second rotating shaft 702. The outer circumferential surface of the two second rotating shafts 702 is covered with the second conveyor belt 703. The outer surface of the second conveyor belt 703 is symmetrically fixed with second baffles 705. The second conveyor belt 703 between the two second baffles 705 is evenly provided with first conical holes 704. Two support rods 901 at the bottom of a vertical plate 9 are fixed to the middle of the two second frames 701.

[0066] When large mulberries enter the first processing structure 7, the two second frames 701 within the first processing structure 7 serve as load-bearing structures. Two second rotating shafts 702 within these frames are connected to a second conveyor belt 703. One of the second rotating shafts 702 is connected to an external drive structure to drive its rotation, thereby rotating the second conveyor belt 703. When a large number of large mulberries enter the second conveyor belt 703, they will temporarily accumulate. As the second conveyor belt 703 rotates, the mulberries will pass under the upright plate 9. The gap between the first plastic strip 902 under the upright plate 9 and the second conveyor belt 703 is insufficient for a complete mulberry to pass through. Therefore, the mulberries will be pushed backward until they enter the first conical hole 704 on the second conveyor belt 703 vertically. At this time, the height of the mulberry protruding from the first conical hole 704 is less than the distance between the first plastic strip 902 and the second conveyor belt 703, allowing it to pass through. If the mulberry stem is at the top, it will be broken when it touches the first plastic strip 902; if it is at the bottom, it will be broken by the second plastic strip 903, thus completing the process of removing the stem. The first conical hole 704 is actually an inverted cone shape. When the second conveyor belt 703 reaches the end, the mulberries will automatically fall from the first conical hole 704. At this time, the processed mulberries can be collected.

[0067] The second processing structure 8 includes a third frame 801 and a third conveyor belt 803. The inner top of the two third frames 801 is rotatably connected to a third shaft 802. The outer circumferential surface of the two third shafts 802 is covered with the third conveyor belt 803. The outer surface of the third conveyor belt 803 is symmetrically fixed with third baffles 805. The third conveyor belt 803 between the two baffles 805 is evenly provided with second conical holes 804. Another vertical plate 9 is fixed to the middle of the two third frames 801 by two support rods 901 at the bottom. The second baffles 705 and the third baffles 805 are both made of soft plastic and can move synchronously with the conveyor belt.

[0068] When normal-sized mulberries enter the second processing structure 8, the two third frames 801 in the second processing structure 8 serve as load-bearing structures. Two third rotating shafts 802 within these structures are connected to a third conveyor belt 803. One of the third rotating shafts 802 is connected to an external drive structure to drive its rotation, thereby rotating the third conveyor belt 803. When a large number of normal-sized mulberries enter the third conveyor belt 803, they will temporarily accumulate. As the third conveyor belt 803 rotates, the mulberries will pass under the upright plate 9. The gap between the first plastic strip 902 under the upright plate 9 and the third conveyor belt 803 is insufficient to allow a normal-sized mulberry to pass through. So the mulberries are pushed backward until they enter the second conical hole 804 on the third conveyor belt 803 vertically. At this time, the height of the mulberry protruding from the second conical hole 804 is less than the distance between the first plastic strip 902 and the third conveyor belt 803, allowing it to pass through. If the mulberry stem is at the top, it will be broken when it touches the first plastic strip 902; if it is at the bottom, it will be broken by the second plastic strip 903, thus completing the process of removing the stem. The second conical hole 804 is actually an inverted cone. When the third conveyor belt 803 reaches the end, the mulberries will automatically fall from the second conical hole 804. At this time, the processed mulberries can be collected.

[0069] This completes the final step in mulberry sorting. The mechanized processing of the mulberry stems ensures high-quality mulberry quality control with minimal manual labor and a high degree of automation. It allows for efficient sorting and quality monitoring of mulberries, quickly yielding mulberries of varying sizes and qualities, which facilitates subsequent processing.

[0070] Example 2

[0071] The first plastic strip 902 and the second plastic strip 903 may contain blades, which can be selected according to actual needs. The height at which the blades are embedded in the first plastic strip 902 and the second plastic strip 903 is controlled according to the height of the mulberry protruding from the first conical hole 704 and the second conical hole 804. This method is used for mulberry varieties where the fruit stem is difficult to break.

[0072] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
