Description

Technical Field

[0001] This invention relates to the field of vegetable cleaning equipment, specifically a cleaning device and method for leafy green vegetables. Background Technology

[0002] Leafy green vegetables are a type of fast-growing vegetable primarily valued for their tender green leaves, petioles, and stems. They are widely popular due to their short growing season, flexible harvesting, diverse varieties, and rich nutritional value. Common leafy green vegetables include spinach, bok choy, and amaranth. The edible part of most leafy green vegetables is their leaves, and the roots usually need to be removed before cooking. However, the leaves of leafy green vegetables tend to overlap near the root, with adjacent leaves closely packed together. This often results in dirt getting trapped between the leaves near the root. For home-based businesses or small restaurants, the roots can be manually removed, and the dirt can be washed away by hand without much time or labor. However, for large-scale food companies, it is difficult to manually clean leafy green vegetables due to low efficiency and high labor costs.

[0003] In existing technologies, most food companies producing dehydrated leafy green vegetable products use equipment such as bubble washing machines to clean leafy green vegetables. While this method is effective at cleaning the upper parts of the leaves, it struggles to remove the dirt and grime from the parts of the leaves closer to the roots. Even after the roots are pre-cut, dirt adheres tightly to the tightly packed leaves, resulting in poor cleaning. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a green leafy vegetable cleaning device and method, which can cut off the roots of green leafy vegetables, then use a cleaning head to disperse the leaves at the cut end and rub the cleaning head against the dispersed leaves, while using cleaning water to rinse the separated leaves at the cut end, thereby thoroughly cleaning the soil trapped in the roots of the green leafy vegetables.

[0005] To achieve the above objectives, the specific solution adopted by the present invention is as follows:

[0006] A leafy green vegetable washing device includes a rotary drive platform. The rotary drive platform is driven and connected to a horizontally arranged turntable. Multiple connecting components are fixedly connected to the peripheral wall of the turntable. The connecting components are fixedly connected to a frame for accommodating leafy green vegetables and a gripper for clamping leafy green vegetables. The gripping part of the gripper extends into the frame. A first base plate, a second base plate, and a third base plate are fixedly arranged on the main body of the rotary drive platform. A support plate for supporting leafy green vegetables is elliptically arranged on the first base plate. A cutting blade for cutting the roots of leafy green vegetables is rotatably arranged on the second base plate. A washing box is fixedly arranged on the third base plate. Multiple upward-arranged nozzles are fixedly arranged on the inner wall of the washing box. All the nozzles are connected to a water supply pipe. A washing head for washing the lower part of leafy green vegetables is also elliptically arranged in the washing box.

[0007] As the turntable rotates, the frame can pass sequentially above the support plate, to the side of the cutting blade, and above the cleaning box.

[0008] Preferably, the connecting assembly includes a plurality of connecting rods fixedly connected to the peripheral sidewall of the turntable, and the connecting rods extend horizontally. The plurality of connecting rods are fixedly connected to a mounting plate. The pneumatic gripper is fixedly mounted on the mounting plate. A through groove is provided on the frame for the clamping part to pass through.

[0009] Preferably, a support driving cylinder is fixedly connected to the lower surface of the first substrate. The piston rod of the support driving cylinder passes upward through the first substrate and is fixedly connected to the support plate. The support plate is parallel to the first substrate.

[0010] Preferably, a cutting drive motor for driving the cutting blade to rotate is fixedly installed on the second substrate, and a through hole is opened on the second substrate so that the roots of leafy green vegetables can pass through the through hole after being cut off by the cutting blade. A root collection box for receiving the roots is provided below the second substrate.

[0011] Preferably, a tray is fixedly connected to the lower surface of the third substrate by a plurality of support columns, a cleaning drive cylinder is fixedly disposed on the tray, a cleaning drive motor is driven by the cleaning drive cylinder, the cleaning drive motor is used to drive the cleaning head to rotate, and a through hole is provided on the third substrate for the cleaning head to pass through.

[0012] Preferably, the cleaning head is conical, with the tip of the cleaning head pointing upwards, and a plurality of soft cleaning strips are fixedly connected to the peripheral sidewall of the cleaning head.

[0013] Preferably, an installation tube is provided in the through hole, a fixing plate is fixedly provided on the upper inner wall of the installation tube, the cleaning drive motor is fixedly provided on the fixing plate, a sealing plate is fixedly provided on the lower inner wall of the installation tube, and the piston rod of the cleaning drive cylinder is fixedly connected to the sealing plate.

[0014] Preferably, the water supply pipe is annular and fixedly sleeved on the outer peripheral side wall of the cleaning box. The water supply pipe is connected to multiple connecting pipes. After passing through the cleaning box, the connecting pipes are connected to the nozzles. The water supply pipe is also connected to a water supply pipe.

[0015] Preferably, an inclined water guide groove is fixedly connected to the lower surface of the third substrate. The upper end of the water guide groove is connected to the cleaning box through a drainage channel formed on the third substrate. The lower end of the water guide groove is connected to a downwardly extending drain pipe. A wastewater collection tank is provided below the drain pipe.

[0016] A method for cleaning leafy green vegetables, based on the aforementioned leafy green vegetable cleaning equipment, includes the following steps:

[0017] The leafy green vegetables are placed into the frame and supported by the support plate.

[0018] Use the pneumatic gripper to clamp the leafy green vegetables;

[0019] The rotary drive table is driven to move, and the rotary drive table drives the turntable to rotate, so that the turntable drives the frame and the leafy green vegetables to move synchronously.

[0020] When the leafy green vegetables move to the side of the cutting blade, the cutting blade is driven to rotate and cut off the roots of the leafy green vegetables;

[0021] When the leafy green vegetables move above the washing box, the washing head is driven upward to the cut end of the leafy green vegetables to open up the lower part of the vegetables, and the nozzle is used to spray washing water onto the leafy green vegetables.

[0022] This invention can cut off the roots of leafy green vegetables, and then use a washing head to disperse the leaves at the cut point, rubbing the washing head against the dispersed leaves. Simultaneously, washing water is used to rinse the separated leaves at the cut point, thus thoroughly cleaning the soil trapped around the roots of the leafy green vegetables. Furthermore, when placing the leafy green vegetables into the frame, a height-adjustable support plate supports them. The position of the lower end of the leafy greens can be adjusted according to the type of leafy green. Since the height of the cutting blade is fixed, adjusting the support plate changes the relative position of the leafy greens when in contact with the cutting blade, thereby cutting the roots of the leafy greens at the appropriate position and avoiding waste.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 4As shown, a leafy vegetable washing device includes a rotary drive platform 1, which is driven by a horizontally arranged turntable 3. Multiple connecting components are fixedly connected to the peripheral wall of the turntable 3. These connecting components are fixedly connected to a frame 9 for accommodating leafy vegetables 10 and a gripper 6 for holding the leafy vegetables 10. The gripping part 7 of the gripper 6 extends into the frame 9. A first base plate 11, a second base plate 14, and a third base plate 23 are fixedly arranged on the main body of the rotary drive platform 1. A support plate 13 for supporting the leafy vegetables 10 is elliptically arranged on the first base plate 11. A cutting blade 17 for cutting the roots of the leafy vegetables 10 is rotatably arranged on the second base plate 14. A washing box 27 is fixedly arranged on the third base plate 23. Multiple upward-facing nozzles 26 are fixedly arranged on the inner wall of the washing box 27. All nozzles 26 are connected to a water supply pipe 24. A washing head 29 for washing the lower part of the leafy vegetables 10 is also elliptically arranged in the washing box 27. As the frame 9 rotates with the turntable 3, it can pass sequentially above the support plate 13, to the side of the cutting blade 17, and above the cleaning box 27.

[0031] When washing leafy green vegetables 10, the leafy green vegetables 10 are first placed into the frame 9 and placed on the support plate 13. By adjusting the height of the support plate 13, the height of the leafy green vegetables 10 in the frame 9 can be changed. For different types of leafy green vegetables 10, the leafy green vegetables 10 can be adjusted to different heights to facilitate the subsequent cutting of the roots of the leafy green vegetables 10. Then, the leafy green vegetables 10 are clamped by the pneumatic gripper 6. Subsequently, the rotary drive table 1 drives the turntable 3 to rotate. During the rotation of the turntable 3, the frame 9 is rotated synchronously through the connecting component, thereby changing the position of the leafy green vegetables 10. When the frame 9 moves to the side of the cutting blade 17, the cutting blade 17 is driven to rotate and cut off the roots of the leafy green vegetable 10. Then, when the frame 9 moves above the washing box 27, the nozzle 26 sprays washing water onto the cut surface of the leafy green vegetable 10, while the washing head 29 moves upward. The washing head 29 squeezes and disperses the cut surface of the leafy green vegetable 10, allowing the washing water to fully penetrate between the leaves at the cut surface. The washing head 29 then rotates, and the friction between the washing head 29 and the leaves thoroughly cleans the leaves at the cut surface, removing all dirt trapped between the leaves. Finally, after the frame 9 and the washing box 27 are separated, the pneumatic gripper 6 can be released, allowing the leafy green vegetable 10, with its roots removed and the dirt between the leaves thoroughly cleaned, to be thrown down. It is then transported by a conveyor belt or other conveying device to a bubble washing machine or other washing device for further cleaning. The conveyor belt and bubble washing machine are conventional technologies in the field and will not be described in detail here.

[0032] This invention can cut off the roots of leafy green vegetables 10, and then use a washing head 29 to disperse the leaves at the cut point, allowing the washing head 29 to rub against the dispersed leaves. Simultaneously, washing water is used to rinse the separated leaves at the cut point, thereby thoroughly cleaning the soil trapped at the roots of the leafy green vegetables 10. Furthermore, when placing the leafy green vegetables 10 into the frame 9, a height-adjustable support plate 13 supports the leafy green vegetables 10. The position of the lower end of the leafy green vegetables 10 can be adjusted according to the type of leafy green vegetable 10. Since the height of the cutting blade 17 is fixed, adjusting the support plate 13 can change the relative position of the leafy green vegetables 10 when in contact with the cutting blade 17, thereby cutting off the roots of the leafy green vegetables 10 at the appropriate position and avoiding waste.

[0033] The specific structure of the connecting assembly is as follows: the connecting assembly includes multiple connecting rods 4 fixedly connected to the peripheral sidewall of the turntable 3, and the connecting rods 4 extend horizontally. Multiple connecting rods 4 are jointly fixedly connected to a mounting plate 5. A pneumatic gripper 6 is fixedly mounted on the mounting plate 5. A through slot 8 is provided on the frame 9 for the clamping part 7 to pass through. Using multiple connecting rods 4 to connect the mounting plate 5 and the turntable 3 ensures the stability of the mounting plate 5, reduces the load on the turntable 3, and ensures stable rotation of the turntable 3.

[0034] To facilitate the raising and lowering of the support plate 13 to change the height of the leafy vegetables 10, a support drive cylinder 12 is fixedly connected to the lower surface of the first base plate 11. The piston rod of the support drive cylinder 12 passes upward through the first base plate 11 and is fixedly connected to the support plate 13. The support plate 13 and the first base plate 11 are parallel to each other. Before washing the leafy vegetables 10, the height of the support plate 13 is adjusted according to the type of leafy vegetables 10. For leafy vegetables 10 with taller plants and longer roots, the height of the support plate 13 can be lowered; for leafy vegetables 10 with shorter plants or shorter roots, the height of the support plate 13 can be raised. The higher the height of the support plate 13, the shorter the length of the vegetable root cut by the cutting blade 10; conversely, the lower the height of the support plate 13, the longer the length of the vegetable root cut by the cutting blade 10. For example, for Chinese cabbage, the height of the support plate 13 can be lowered; for Shanghai bok choy, the height of the support plate 13 can be raised. The support plate 13 is raised and lowered by the support drive cylinder 12, which has a simple structure and is easy to control.

[0035] The cutting blade 17 is specifically configured as follows: a cutting drive motor 16 for driving the cutting blade 17 to rotate is fixedly mounted on the second base plate 14. A through hole 15 is provided on the second base plate 14, allowing the roots of the leafy green vegetables 10 to pass downwards through the through hole 15 after being cut by the cutting blade 17. A root collection box 19 for receiving the roots is provided below the second base plate 14. When the leafy green vegetables 10 move to the side of the cutting blade 17 along with the frame 9, the cutting drive motor 16 starts and drives the cutting blade 17 to rotate, thereby cutting off the roots of the leafy green vegetables 10. Because the height of the leafy green vegetables 10 is adjustable, the height of the cutting blade 17 no longer needs to be adjusted, simplifying the drive structure. The cut vegetable roots fall downwards and pass through the through hole 15 into the vegetable root collection box 19. After a certain number of vegetable roots have been collected in the vegetable root collection box 19, the vegetable roots in the vegetable root collection box 19 can be transferred away as garbage for disposal, and the vegetable root collection box 19 can be cleaned to prevent the growth of microorganisms.

[0036] Furthermore, a discharge pipe 18 can be provided below the second base plate 14. After passing through the through hole 15, the vegetable roots enter the discharge pipe 18 and move along the discharge pipe 18, eventually entering the vegetable root collection box 19. By setting the discharge pipe 18, the movement direction of the vegetable roots can be controlled to ensure smooth collection. The discharge pipe 18 can be fixedly connected to the main body of the rotary drive table 1 via a connecting rod or plate.

[0037] To facilitate the lifting and rotation of the cleaning head 29, a tray 36 is fixedly connected to the lower surface of the third substrate 23 via multiple support columns 35. A cleaning drive cylinder 34 is fixedly mounted on the tray 36, and a cleaning drive motor 30 is connected to the cleaning drive cylinder 34. The cleaning drive motor 30 drives the cleaning head 29 to rotate. A through hole is provided on the third substrate 23 for the cleaning head 29 to pass through. When the leafy green vegetable 10 moves above the cleaning box 27 along with the frame 9, the cleaning drive cylinder 34 activates and drives the cleaning drive motor 30 and the cleaning head 29 to move upward synchronously. During this process, the cleaning drive motor 30 drives the cleaning head 29 to rotate until the cleaning head 29 contacts the broken edge of the leafy green vegetable 10 and squeezes the broken edge to disperse the leaves. At the same time, the cleaning head 29 continuously rubs against the leaves to ensure that the dirt trapped between the leaves is cleaned.

[0038] The specific structure of the washing head 29 is as follows: the washing head 29 is conical, with its tip pointing upwards, and multiple soft washing strips are fixedly connected to its peripheral sidewalls. By making the washing head 29 conical, its tip can be inserted into the cut end of the leafy green vegetable 10, thus easily separating the leaves at the cut. As the soft washing strips rotate synchronously with the washing head 29, they continuously contact and rub against the leaves, thereby cleaning away the dirt adhering to the leaves. Furthermore, the soft washing strips are made of a soft material and will not cause excessive damage to the leaves. In one embodiment of the invention, both the washing head 29 and the soft washing strips can be made of silicone.

[0039] The specific connection method between the cleaning drive motor 30 and the cleaning drive cylinder 34 is as follows: a mounting tube 32 is installed vertically in the through hole, a fixing plate 31 is fixedly installed on the upper inner wall of the mounting tube 32, the cleaning drive motor 30 is fixedly installed on the fixing plate 31, a sealing plate 33 is fixedly installed on the lower inner wall of the mounting tube 32, and the piston rod of the cleaning drive cylinder 34 is fixedly connected to the sealing plate 33. By placing the cleaning drive motor 30 in the mounting tube 32, the cleaning drive motor 30 can be protected to avoid damage caused by water seepage.

[0040] Furthermore, the cleaning drive motor 30 is connected to a rotating plate 38, which seals the upper end of the mounting tube 32. The cleaning head 29 is fixedly mounted on the rotating plate 38, thereby further preventing cleaning water from seeping into the cleaning drive motor 30. A sealing ring 39 can also be fixedly mounted on the third base plate 23. The sealing ring 39 is located inside the cleaning box 27, and the rotating plate 38 can pass through the inner hole of the sealing ring 39. Based on this configuration, when the leafy green vegetables 10 do not need to be cleaned, the rotating plate 38 can retract to the inside of the sealing ring 39 and contact it, preventing residual cleaning water in the cleaning box 27 from flowing downwards and seeping into the cleaning drive motor 30.

[0041] The specific structure and arrangement of the water supply pipe 24 are as follows: the water supply pipe 24 is ring-shaped and fixedly sleeved on the outer peripheral side wall of the cleaning box 27. The water supply pipe 24 is connected to multiple connecting pipes 25. After passing through the cleaning box 27, the connecting pipes 25 are connected to the nozzles 26. The water supply pipe 24 is also connected to a water supply pipe 28.

[0042] To facilitate the recycling of washing water and avoid environmental pollution, an inclined water guide trough 22 is fixedly connected to the lower surface of the third substrate 23. The upper end of the water guide trough 22 is connected to the washing box 27 through a drainage channel 37 formed on the third substrate 23, and the lower end of the water guide trough 22 is connected to a downwardly extending drain pipe 21. A wastewater collection tank 20 is located below the drain pipe 21. After the washing water sprayed from the nozzle 26 washes the leaves at the cut ends of the leafy green vegetables 10, it falls back into the washing box 27 mixed with soil, and then flows downward through the drainage channel 37 into the water guide trough 22. After flowing downward along the water guide trough 22, it finally flows downward through the drain pipe 21 into the wastewater collection tank 20. When a certain amount of wastewater has been collected in the wastewater collection tank 20, the wastewater collection tank 20 can be cleaned separately to prevent the growth of microorganisms.

[0043] Furthermore, a bottom support plate 2 is fixedly connected to the lower part of the main body of the rotary drive table 1. Both the vegetable root collection box 19 and the wastewater collection box 20 can be detachably installed on the bottom support plate 2 for separate cleaning.

[0044] The present invention also provides a method for cleaning leafy green vegetables, based on the above-mentioned leafy green vegetable cleaning device, the method comprising S1 to S5.

[0045] S1. Place the leafy green vegetables 10 into the frame 9 and support the leafy green vegetables 10 using the support plate 13.

[0046] S2. Use the pneumatic gripper 6 to clamp the leafy green vegetable 10. It should be noted that since most leafy green vegetables 10 are shaped like a large top and a small bottom, the clamping force of the pneumatic gripper 6 does not need to be too large. The clamping part 7 can prevent the large leaves on the top of the leafy green vegetable 10 from falling downwards, thereby clamping the leafy green vegetable 10 and avoiding excessive damage to the leafy green vegetable 10.

[0047] S3. Drive the rotary drive table 1 to rotate the turntable 3, so that the turntable 3 drives the frame 9 and the leafy green vegetables 10 to move synchronously.

[0048] S4. When the leafy green vegetable 10 moves to the side of the cutting blade 17, drive the cutting blade 17 to rotate and cut off the root of the leafy green vegetable 10.

[0049] S5. When the leafy green vegetables 10 move above the washing box 27, the driving washing head 29 moves upward to the cut of the leafy green vegetables 10 to open the lower part of the leafy green vegetables 10, and the nozzle 26 sprays washing water onto the leafy green vegetables 10.

[0050] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
