Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an integrated machine for cleaning and packaging leafy vegetables. Background Technology

[0002] Leafy vegetables (such as spinach and rapeseed) need to be processed after harvesting to meet the standards for fresh sale. Specifically, they need to go through a series of pre-processing steps, such as cutting the roots, removing yellow leaves and leaves with pests and diseases, washing, draining water, weighing, and packaging, to remove impurities and defective products before they can be sold in the market.

[0003] Currently, the commercial processing of leafy vegetables mainly relies on manual assembly lines combined with single-function mechanical equipment, which limits overall efficiency and effectiveness. Firstly, key processes such as root cutting and sorting of residual leaves are highly dependent on manual labor, resulting in low efficiency, high labor intensity, and susceptibility to subjective human judgment. This leads to inconsistent processing standards, inconsistencies in processing precision, and the omission of defective leaves, resulting in poor product stability. Secondly, existing processing equipment is fragmented, capable of only performing single functions such as washing and packaging, lacking integrated and compact equipment. Multiple machines operating in series occupy a large area, involve cumbersome process transfers, and are prone to leaf damage and secondary contamination, resulting in poor production continuity and high costs. Finally, traditional sorting equipment has limited identification capabilities, unable to accurately identify subtle defects such as yellow leaves and insect spots, allowing defective products to easily mix into the finished product, significantly reducing the pass rate and market quality of leafy vegetables.

[0004] Chinese patent document CN 113383973 A describes a modular set of equipment for processing root vegetables. This equipment can only clean and cut the roots of leafy vegetables, but cannot package them. Chinese patent document CN 120887067 A describes a clean packaging machine for leafy vegetables. However, the root cutting effect is not good, and there are defects in its use, which need to be improved.

[0005] Therefore, existing processing technologies and equipment cannot meet the current needs for large-scale, standardized, and high-quality processing of leafy vegetables, and there is an urgent need for a fully automated integrated machine that is adapted to the physical characteristics of leafy vegetables.

Detailed Implementation

[0021] Example 1 like Figure 1-20A leafy vegetable cleaning and packaging integrated machine includes a conveying unit 11 mounted on a first frame 1. From right to left, the upper side of the conveying unit 11 is provided with a feeding unit 3, a root-cutting unit 4, a removal unit 6, a spray head 8, and a blowing module 9. An automatic weighing unit 13 is connected to the lower end of the conveying unit 11 via a chute plate 12. The automatic weighing unit 13 is located on the upper part of a second frame 2. The middle and lower parts of the second frame 2 are provided with a covering unit 14, a hot-cutting unit 15, and a transverse platform 16. The leafy vegetables entering the first frame 1 from the feeding unit 3 are processed sequentially by the root-cutting unit 4, the removal unit 6, the spray head 8, and the blowing module 9 before falling onto the automatic weighing unit 13. Then, the covering unit 14 and the hot-cutting unit 15 work together to complete the packaging. Finally, the packaged leafy vegetables are removed from the second frame 2 via the transverse platform 16.

[0022] Leafy vegetables (such as spinach and rapeseed) usually need to go through a series of processes after harvesting, including cutting off the roots, picking out yellow leaves and diseased or pest-infested leaves, washing, draining the water, weighing and packaging, before they can be sold in supermarkets or markets.

[0023] The conveying unit 11 includes a first support roller 1102 and a second support roller 1103 disposed on both sides of the first frame 1. A first motor 1101 is disposed on one side of the first support roller 1102. The first support roller 1102 and the second support roller 1103 are connected by a conveyor belt 1104. The conveyor belt 1104 has a plurality of through holes 1105 evenly distributed on it. After the leafy vegetables are cleaned by the spray head 8, the blower module 9 blows the water on the surface of the leafy vegetables downwards, and then drips from the through holes 1105 into the water collection tank 22.

[0024] A top plate 7 is provided on the upper inner side of the first frame 1. Spray heads 8 and blower modules 9 are located on the lower side of the top plate 7. A water pump is provided on one side of the spray head 8. The water pump sprays the filtered water in the water collection tank 22 to remove the residual soil attached to the surface of the leafy vegetables. The blower module 9 uses a high-pressure air gun, which can quickly form a high-pressure airflow to remove the water from the surface of the wet leafy vegetables. The blower module 9 is equipped with two modes: natural wind and hot air. In warm weather such as summer and autumn, the natural wind mode is used. In relatively cool weather such as winter and spring, the hot air mode is used.

[0025] Meanwhile, relatively sealed spaces are formed on both sides of the spray head 8 and the blower module 9 by baffles 26, ensuring the effectiveness of spraying and drying. The upper part of the baffles 26 is fixedly connected to the top plate 7. The baffles 26 can effectively block the sprayed water to a certain extent, while also ensuring a certain convection effect during blowing, thus improving the efficiency of blowing.

[0026] In a preferred embodiment, a first vision module 5 and a second vision module 25 are also provided on the top of the first frame 1. The first vision module 5 is located between the root cutting unit 4 and the removal unit 6, and the second vision module 25 is located on one side of the blowing module 9. The root cutting unit 4 includes a second motor 401, and a shaft 402 is provided at the end of the second motor 401. The shaft 402 is rotatably mounted on the first frame 1. A flexible roller 404 is provided in the middle of the shaft 402, and a cutter disc 403 is installed on one side of the flexible roller 404 through a connecting sleeve 405.

[0027] The flexible roller 404 is made of cylindrical sponge. The cylindrical sponge is used to press and fix the root cutting process, which eliminates material deviation during the conveying process, ensures the consistency of the root cutting length, and does not damage the vegetable leaves. At the same time, the sponge's ability to squeeze and buffer avoids the problem of crushing the vegetable leaves.

[0028] In a preferred embodiment, the rejection unit 6 includes a top frame 604, which is fixed to the first frame 1 via a fixing seat 605. A third motor 601 is provided on one side of the top frame 604. The end of the third motor 601 is engaged with a drag chain 603 via a sprocket 602. The drag chain 603 is located in a limiting groove 606 at the top of the top frame 604. The end of the drag chain 603 is connected to a brush 608 via a locking block 607.

[0029] The first vision module 5 identifies information about the vegetable leaves. When yellow or rotten leaves appear, the leaves are promptly removed. The conveyor belt 1104 uses sprockets 602 and drag chains 603, which have a fast response speed, strong work adaptability, and good overall heat dissipation. Compared with simple pneumatic blowing or linkage, the slide rail provides extremely high lateral rigidity and linear guidance accuracy, and the brush 608 performs a more crisp and thorough sweeping action.

[0030] In a preferred embodiment, a first limiting plate 27 and a second limiting plate 28 are provided on one side of the cutter head 403. The first limiting plate 27 and the second limiting plate 28 are respectively connected to the first frame 1. A gap 29 is provided between the end of the first limiting plate 27 and the second limiting plate 28. The first limiting plate 27, the second limiting plate 28 and the gap 29 cooperate to form a collection channel 30. The chute plate 12 includes a bottom plate 1202. First baffles 1201 are provided on both sides of the bottom plate 1202. Multiple sliding grooves 1203 are provided on the top of the bottom plate 1202.

[0031] The cut roots and leaves are separated, creating a speed difference. Driven by the conveyor belt 1104, they enter the collection channel 30 and are simultaneously blocked by the first limiting plate 27 and the second limiting plate 28. Finally, they fall into the collection bucket on one side of the first frame 1 (not shown in the figure). The collection bucket is fixed to the outside of the first frame 1 by hooks, which is convenient to install and remove, while ensuring the stability of the overall load-bearing capacity.

[0032] like Figure 13-16 In the preferred embodiment, a pressing module 10 is also provided on the lower side of the blower module 9. The pressing module 10 includes a fourth motor 1001. One side of the fourth motor 1001 is mounted on the support plate 1004 via a first lead screw 1002. The support plate 1004 is threadedly connected to the first lead screw 1002 via a nut seat 1003. Slider blocks 1008 are connected to both sides of the support plate 1004 via adapter rods 1007. Multiple sliders 1008 are connected to each other via a pressure mesh 1010. The sliders 1008 slide on the guide rail 1009, which is located inside the first frame 1.

[0033] It cleverly solves the problem that leaves are prone to splashing, rolling, or even being blown off the production line when drying at high wind speeds. It achieves rapid drying under high air volume, with high drying efficiency and no leaf loss. The fourth motor 1001 drives the first lead screw 1002 to work, changing the position of the support plate 1004, thereby realizing the height adjustment of the pressing net 1010. The pressing net also has a certain degree of flexibility and toughness, avoiding crushing the leafy vegetables. The high-speed airflow blows away the moisture on the surface of the leafy vegetables through the mesh of the pressing net, ensuring that the leafy vegetables are clean and tidy.

[0034] In a preferred embodiment, a sleeve 1005 is provided on the upper part of the support plate 1004, and a cover plate 1006 is threadedly connected to the sleeve 1005. The first lead screw 1002 is located inside the sleeve 1005. Fixing frames 21 are provided on both sides of the sleeve 1005. A water collection chamber 22 is slidably connected inside the fixing frame 21. A filter cloth is provided inside the water collection chamber 22. The water collection chamber 22 is connected to the spray head 8 through a pipeline.

[0035] The filter cloth, made of non-woven fabric, is positioned in the upper middle part of the water collection chamber 22, forming a mesh structure. This allows for the collection and filtration of water dripping from the conveyor belt 1104, enabling water reuse while maintaining a relatively clean and stable working environment, thus reducing operating costs. Simultaneously, the sleeve 1005 and cover plate 1006 are threaded together for easy disassembly. These components provide a relatively enclosed environment for the first lead screw 1002, preventing water from the top from directly entering and wetting it, thus affecting its operation and time, and improving the overall adaptability of the device.

[0036] like Figure 17-20In the preferred embodiment, the automatic weighing unit 13 includes a fifth motor 1301, the end of which is connected to a weighing flap 1303 via an adapter tube 1302. The covering unit 14 includes two parallel third support rollers 1401 and a fourth support roller 1402, which are located on opposite sides of the second frame 2. The third support rollers 1401 and the fourth support rollers 1402 are connected by a covering film 1403. The hot cutting unit 15 includes a sixth motor 1501, which is meshed with a first rack frame 1503 and a second rack frame 1504 via a gear 1502. The middle portions of the first rack frame 1503 and the second rack frame 1504 are respectively provided with a first hot cutting blade 1505 and a second hot cutting blade 1506.

[0037] Four weighing sensors are evenly distributed at the bottom of the weighing flip plate 1303 to monitor the weight in real time. When the leafy vegetables accumulate to a certain weight on the weighing flip plate 1303, the fifth motor 1301 drives the weighing flip plate 1303 to rotate and tilt it toward the covering film 1403. The covering film 1403 is made of plastic wrap, which has good overall toughness and good wrapping effect. After tilting, the fifth motor 1301 drives the weighing flip plate 1303 to return to a horizontal state.

[0038] Furthermore, drive motors are also provided on the outer sides of the third support roller 1401 and the fourth support roller 1402. The two drive motors work in opposite directions and have the same rotation speed and frequency, which ensures that the leafy vegetables are stably caught after falling through the load-bearing flap 1303 on the self-supporting unit 13, while avoiding impact damage to the plastic wrap and providing a certain buffer space.

[0039] The first hot cutting blade 1505 and the second hot cutting blade 1506 are at the same height and coaxial. The lowest point of the covering film 1403 is located at the center of the first hot cutting blade 1505 and the second hot cutting blade 1506. That is, when the leafy vegetables fall into the upper part of the covering film 1403, the third support roller 1401 and the fourth support roller 1402 unfold the covering film 1403. The covering film 1403 continues to descend with the leafy vegetables. Then, the sixth motor 15011 drives the first hot cutting blade 1505 and the second hot cutting blade 1506 to move towards each other. Finally, the covering film 1403 is cut and fused. After the fusion is completed, the leafy vegetables wrapped by the covering film 1403 fall onto the transverse platform 16.

[0040] In a preferred embodiment, the transverse platform 16 includes a support 1602, a seventh motor 1601 is provided on one side of the support 1602, a second lead screw 1603 is provided at the end of the seventh motor 1601, the second lead screw 1603 is connected to the platform plate 1606 through a slide 1605, a guide rod 1604 passes through the support 1602 and the slide 1605, a hot air blower 23 is also provided on the upper side of the seventh motor 1601, a flat tube 24 is provided at the end of the hot air blower 23, and the flat tube 24 is positioned directly opposite the top of the platform plate 1606.

[0041] The hot air blower 23 directs hot air through the flat tube 24 to the platform plate 1606, thereby allowing the covering film 1403 to shrink and cover the surface of the leafy vegetables better, thus improving the overall packaging effect and reducing the amount of covering film 1403 used, which is energy-saving and environmentally friendly.

[0042] like Figure 10-12 In the preferred embodiment, the feeding unit 3 includes a top plate 301, with an installation port 302 in the middle of the top plate 301. A funnel 303 is provided inside the installation port 302. Multiple vertical plates 304 are arranged parallel to each other on both sides of the inside of the funnel 303. A partition 305 is detachably provided on the vertical plate 304. Two straight plates 307 are arranged parallel to each other at the bottom of the vertical plate 304. The straight plates 307 are positioned directly opposite the conveying unit 11. The two straight plates 307 are connected by a follower plate 20. A linear motor 19 for driving the follower plate 20 is provided on one side of the straight plate 307. A third camera module 17 and a fourth camera module 18 are respectively provided on the upper and lower sides of the vertical plate 304.

[0043] The vertical plates 304 on both sides work together to ensure that the leafy vegetables are supported by the vertical plates 304 when they are put into the funnel 303. This point support prevents the vegetables from being unable to slide down due to friction. In addition, the bottom opening formed by the vertical plates 304 on both sides allows the leafy vegetables to pass through one by one, rather than all of them falling directly. The position between the two partitions 305 is adjusted according to the length of the leafy vegetables to ensure that the roots of the leafy vegetables can be cut after entering the lower conveyor belt 1104. Furthermore, the third camera module 17 and the fourth camera module 18 can sense and identify the leafy vegetables to be falling from a high position and a low position, respectively. When the leafy vegetables are about to fall onto the conveyor belt 1104 through the follower plate 20, the tilt angle of the follower plate 20 can be changed to change the parabolic trajectory of the falling vegetables, thereby better aligning the roots of the leafy vegetables with the cutter head 403.

[0044] In a preferred embodiment, a slot 306 is provided at the lower part of the partition 305, and the slot 306 is inserted into the vertical plate 304. The linear motor 19 includes a fixing part 1901 and a telescopic rod 1902. The fixing part 1901 is fixed by a straight extension plate 311 and a straight plate 307. An opening 310 is provided through the straight plate 307 at the lower part of the linear motor 19. Two slots 308 are arranged in parallel on the other side of the straight plate 307. A first ear plate 309 is provided outside the slots 308. The follower plate 20 includes an inclined plate 2002, and side plates 2001 are respectively provided on both sides of the inclined plate 2002. The side plate 2001 on one side is hinged through a second ear plate 2003 and a slot 308. The side plate 2001 on the other side passes through an opening 310 through a third ear plate 2004. An oblong hole 2005 is provided on the third ear plate 2004. The telescopic rod 1902 passes through the oblong hole 2005. A baffle 1903 is provided at the end of the telescopic rod 1902.

[0045] In actual operation, the system sets parameters to identify the root length and the position of the falling leafy greens using the third camera module 17 and the fourth camera module 18. Correspondingly, the tilt of the follower plate 20 is adjusted. That is, after the leafy greens fall and impact the follower plate 20, the follower plate 20 provides a supporting force that changes the direction of the fall, thus altering the leafy greens' landing trajectory. When the root of the leafy green is long or the leafy greens are short overall, the linear motor 19 extends the telescopic rod 1902 to its maximum length. At this time, the follower plate 20 is at its maximum tilt angle to one side. With the cooperation of the follower plate 20, the leafy greens move closer to the cutter disc 403, thus completing the root cutting. Through the above operations, the root cutting effect of the leafy greens is achieved, with rapid adjustment. The system automatically and flexibly adjusts according to the position of the leafy greens in the funnel 303, their own length, and the length of the root, ensuring stable root cutting. The overall structure is flexible in control, and the actions are precise and efficient.

[0046] The work process is as follows: S1. Funnel feeding and sponge pressing and root cutting: The leafy vegetables to be processed are guided into the conveyor belt through the funnel, and the roots are attached to the limiting plate. During the conveying process, the leafy vegetables are pressed down and fixed by the cylindrical sponge above, and the root of the leafy vegetables is precisely cut off by the rotating cutter driven by the motor. S2. Visual Recognition and Slide Rail Sweeping: After the roots are cut, the leafy vegetables enter the visual recognition area. The system calls the YOLO model to perform image analysis. If yellow leaves or pests are identified, the chain and sprocket mechanism drives the drawer slide rail and cleaning brush to make a horizontal reciprocating motion, sweeping the unqualified products out of the main water line. S3, Spraying Cleaning and Anti-Splash Drying: Qualified leafy vegetables continue to be conveyed and sprayed with water; then the vision module detects that the leafy vegetables have entered the drying area, the system controls the screw mechanism to drive the protective net to press down and fix the leaves, the fan is turned on for rapid drying, and after the drying is completed, the pressure net is raised and reset. S4. Inclined weighing and follow-up heat shrink packaging: After the leafy vegetables are dried, they fall into the weighing platform for weight accumulation. Once the weight reaches the standard, the weighing platform automatically tilts to release the vegetables. The leafy vegetables slide onto the double-shaft plastic wrap below, and the shafts roll synchronously to buffer the impact. S5. Then the system controls the sealing device to wrap the plastic wrap, turns on the hot air blower to make the film shrink and adhere to the leafy vegetables, and finally completes the heat-melting seal by delayed heating. S6. Move the packaged finished products from inside the second frame 2 to the end, where they are manually collected.
