Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of vegetable washing machines, specifically relating to a fresh vegetable washing machine with self-cleaning function. Background Technology
[0002] Cleaned vegetables, also known as fresh sterilized vegetables, refer to ready-to-cook vegetables that have undergone processing, washing, and sterilization in a sterile environment and are then vacuum-packed. They must meet standards for pesticide residues and total bacterial count. The processing involves harvesting, sorting, preservation, and cold chain storage and transportation, resulting in products that are convenient and hygienic.
[0003] This vegetable washing machine uses a bubble water bath cleaning method and is suitable for cleaning leafy vegetables. Customization is available to meet specific product quality requirements. The equipment includes a bubble generator that tumbles the material, effectively removing pesticide residues from the surface. Appropriate chemicals can be added for disinfection and color fixing. Floating debris overflows from the overflow tank, while sediment is discharged from the drain, achieving the desired cleaning effect. This bubble washing machine is designed for materials with high shape requirements and is suitable for cleaning and soaking granular, leafy, and root vegetables, fruits, aquatic products, and Chinese herbal medicines.
[0004] During the vegetable washing process, multiple spray heads are often set up at multiple fixed locations for spraying and cleaning. Although this design can achieve the purpose of cleaning, the structural design cost is high and water is wasted. At the same time, the filter plates inside the box are prone to clogging during the purification process, which is not conducive to the safe use of the equipment. In addition, during the vegetable washing process, due to the density of vegetables or hollow buoyancy, some vegetables will remain floating, which may prevent the vegetables from effectively contacting the water, thus affecting the washing quality and hindering the subsequent processing and packaging of vegetables. Summary of the Invention
[0005] The purpose of this invention is to provide a fresh vegetable cleaning machine with a self-cleaning function to solve the technical problems of high structural component design costs and water waste caused by multiple spray heads performing spray cleaning work at multiple fixed positions, and the easy clogging of the filter plate inside the box during the isolation purification process, which is not conducive to the safe use of the equipment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Fresh vegetable washing machines with self-cleaning function include:
[0008] The first cleaning mechanism includes a first motor placed on a first housing, the output shaft of the first motor extending to a movable shaft, the movable shaft being connected to the central shaft on the first rotating tooth via a first conveyor belt, the outer wall of the first rotating tooth meshing with a second rotating tooth, one end of the first rotating tooth and the second rotating tooth being fixedly fixed on a first eccentric wheel, and one end of the first rotating shaft on the movable shaft and the second rotating tooth being connected to a diverter plate extending into the interior of the first housing.
[0009] The two ends of the outer wall of the first eccentric wheel movably abut against the upper pressure plate and the lower pressure plate, respectively. The upper pressure plate and the lower pressure plate are connected to the side wall of the first housing by the first spring. A lifting rod is connected to the top of the upper pressure plate. A cam groove is opened on the outer edge of the lifting rod. The outer wall of the cam groove abuts against the protrusion on the rotating rod. An annular groove is opened on the outer edge of the rotating rod, and the top of the rotating rod is connected to the top of the inner wall of the first housing by a bearing.
[0010] Furthermore, the diverting plates are arranged in a ring array on both the movable shaft and the first rotating shaft, and the movable shaft and the first rotating shaft rotate in opposite directions. The ring groove is connected to the second rotating shaft inside the cover via a second conveyor belt. Swing arms are fixedly installed at both ends of the second rotating shaft. One end of the swing arm is connected to a spray pipe placed above the diverting plate, and the other end is connected to a water storage box placed on the outer wall of the first housing via a conduit.
[0011] Furthermore, both ends of the cover are fixed to the side wall of the first housing by crossbeams. The extension of the bottom end of the lower pressure plate penetrates the first housing and extends to the mounting rod on the side wall of the first housing. The upper pressure plate and the lower pressure plate are connected to the sliding groove along the height direction of the side wall of the first housing. The bottom of the mounting rod is detachably mounted with a top rod through a frame. A filter plate is fixed to the side wall of the first housing below the top rod. The filter holes on the filter plate are connected to the top rod.
[0012] Furthermore, a cleaning chamber is formed between the filter plate and the bottom of the inner wall of the first housing, and a water storage box is connected to the opening of the cleaning chamber through a circulation pump on a conduit.
[0013] Furthermore, it also includes a second cleaning mechanism, which includes a second motor mounted on a second housing. The output shaft of the second motor extends to a reciprocating screw. A second eccentric wheel and a first bevel gear are fixedly connected to the outer wall of the reciprocating screw. Both ends of the reciprocating screw are helically driven with sliders that move in the same direction. One end of the slider passes through the second housing and extends to the outer wall of the movable box. The top of the movable box is provided with a feed inlet, and cleaning holes adapted to it are opened around the movable box.
[0014] Furthermore, the outer wall of the first bevel gear meshes with a second bevel gear fixed on the third rotating shaft. The third rotating shaft is connected to a stirring rod extending to the inner wall of the moving box. The outer wall of the moving box is provided with a strip groove connected to the third rotating shaft. Both ends of the moving box and the side wall of the second housing are connected by telescopic rods. The top of the second eccentric wheel moves against the push rod.
[0015] Furthermore, the top of the push rod is connected to an extrusion plate placed above the moving box via a bending rod. The top of the extrusion plate is connected to an extension end placed on the side wall of the moving box via a second spring. An movable opening connected to the bending rod is provided on the outer wall of the second housing. The movable opening is a telescopic sealing structure design.
[0016] Furthermore, an ultrasonic generator is provided below the mobile box and placed at the bottom of the inner wall of the second housing. An active cavity is formed between the side wall of the second housing and the mobile box. The top of the extrusion plate is triangular or trapezoidal.
[0017] Furthermore, a conveyor line is provided between the first and second cleaning mechanisms. The conveyor line is installed on the base plate and extends in a preset direction to carry and transport vegetables.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0019] (1) In this invention, the first cleaning mechanism can perform preliminary cleaning of vegetables. The first motor starts and drives the rotation of the movable shaft. Under the action of the first conveyor belt and mechanical transmission, the diversion plates at both ends can rotate in opposite directions, thereby achieving the effect of material transportation and diversion. During the rotation of the first and second rotating teeth, the first eccentric wheel can be driven to rotate synchronously. With the help of the first spring, the rotation of the first eccentric wheel can be converted into the up and down movement of the upper and lower pressure plates. During the up and down movement of the upper pressure plate, with the help of the cam groove on the lifting rod and the protrusion on the rotating rod, the vertical movement of the lifting rod can be converted into the rotational movement of the rotating rod on the bearing. At the same time, the bearing on the rotating rod can ensure the free rotation of the rotating rod and also allow the bearing to provide corresponding support force to the rotating rod. During the rotation of the rotating rod, under the action of the second conveyor belt, the second rotating shaft can be driven to rotate back and forth. In this way, the second rotating shaft can drive the spray pipe to swing back and forth at the corresponding angle in the plane. With the help of the spray pipe, the vegetables on the diversion plate can be sprayed and cleaned evenly. The cleaning effect is good, the product quality is improved, and it helps to save water and protect the environment. The design is simple and reasonable, and the integrated performance is strong.
[0020] (2) In this invention, the lower pressure plate can drive the installation rod to move synchronously through the bending rod during the up and down movement. During the movement, the installation rod can pass through the filter holes on the filter plate through the top rod. This not only prevents the filter plate from clogging during operation, but also ensures the normal purification and filtration of the filter plate. At the same time, the filter plate adopts a pull-out movable structure design, which can effectively clean the impurities on the filter plate and facilitate personnel operation. The filtered water can enter the water storage box through the circulation pump for secondary use. It has good environmental protection effect and strong application performance.
[0021] (3) In this invention, the second cleaning mechanism can perform secondary cleaning of vegetables. First, the vegetables after preliminary cleaning are placed into the moving box. The second motor starts and drives the reciprocating screw, the second eccentric wheel and the first bevel gear to rotate synchronously. Under the action of the screw transmission, the slider drives the moving box to move horizontally back and forth in the second housing. Under the action of gear meshing transmission, the first bevel gear can drive the stirring rod on the third rotating shaft to rotate inside the moving box. Since the moving box has a strip groove, in conjunction with the horizontal movement of the moving box itself, the stirring rod can stir and clean the vegetables in various positions in the water during the rotation process, and can also ensure the normal movement of the moving box. During the rotation of the cam, in conjunction with the extrusion plate on the second spring, the rotational movement of the second eccentric wheel can be transmitted to the extrusion plate through the push rod, and the extrusion plate can move up and down. This can squeeze the vegetables floating on the water surface into the water, thereby effectively contacting the water and the stirring rod, further improving the cleaning effect. The vegetables are cleaned, which is convenient for subsequent processing and packaging work, and improves the stability of the cleaning machine. Attached Figure Description

[0034] 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.
[0035] Reference manual attached Figure 1 - Appendix Figure 10 As shown, a fresh vegetable washing machine with self-cleaning function includes:
[0036] The first cleaning mechanism 1 includes a first motor 3 placed on the first housing 2. The output shaft of the first motor 3 extends to the movable shaft 4. The movable shaft 4 is connected to the central shaft on the first rotating tooth 5 through a first conveyor belt 6. The outer wall of the first rotating tooth 5 is engaged with a second rotating tooth 7. One end of the first rotating tooth 5 and the second rotating tooth 7 are fixed on the first eccentric wheel 8. One end of the first rotating shaft 9 on the movable shaft 4 and the second rotating tooth 7 is connected to a diverter plate 10 extending into the interior of the first housing 1.
[0037] The first cleaning mechanism 1 can perform preliminary cleaning of vegetables. The first motor 3 starts and drives the rotating shaft 4. Under the action of the first conveyor belt 6 and mechanical transmission, the diverter plates 10 at both ends can rotate in opposite directions, thereby achieving the effect of material transportation and diversion. During the rotation of the first rotating tooth 5 and the second rotating tooth 7, the first eccentric wheel 8 can be driven to rotate synchronously. With the help of the first spring 13, the rotation of the first eccentric wheel 8 can be converted into the up and down movement of the upper pressure plate 11 and the lower pressure plate 12. During the up and down movement of the upper pressure plate 11, with the help of the cam groove 15 on the lifting rod 14 and the protrusion 17 on the rotating rod 16, the vertical movement of the lifting rod 14 can be converted into the vertical movement of the lifting rod 14. The rotational motion of the rotating rod 16 is replaced by the rotational motion of the bearing on the rotating rod 16. The bearing on the rotating rod 16 allows the rotating rod 16 to rotate freely and also provides corresponding support force to the rotating rod 16. During the rotation of the rotating rod 16, under the transmission action of the second conveyor belt 19, it can drive the second rotating shaft 21 to rotate back and forth. In this way, the second rotating shaft 21 can drive the spray pipe 23 to swing back and forth at a corresponding angle in the plane. In conjunction with the spray pipe 23, the vegetables on the diversion plate 10 can be evenly sprayed and cleaned. The cleaning effect is good, the product quality is improved, and it helps to save water and protect the environment. The design is simple and reasonable, and the integrated performance is strong.
[0038] The two ends of the outer wall of the first eccentric wheel 8 are respectively in contact with the upper pressure plate 11 and the lower pressure plate 12. The upper pressure plate 11 and the lower pressure plate 12 are connected to the side wall of the first housing 2 by the first spring 13. The top of the upper pressure plate 11 is connected to the lifting rod 14. The outer edge of the lifting rod 14 is provided with a cam groove 15. The outer wall of the cam groove 15 is in contact with the protrusion 17 on the rotating rod 16. The outer edge of the rotating rod 16 is provided with an annular groove 18, and the top of the rotating rod 16 is connected to the top of the inner wall of the first housing 2 through a bearing.
[0039] Specifically, the first conveyor belt 6 set between the movable shaft 4 and the first rotating tooth 5 can expand the center distance between the first rotating tooth 5 and the second rotating tooth 7, thereby facilitating the normal rotation between the two end splitter plates 10 and avoiding motion interference between the transmission components during the operation. In addition, the first eccentric wheel 8 at one end of the first rotating tooth 5 and the second rotating tooth 7 is set perpendicularly, which facilitates the normal rotation between the cams. During the reverse rotation, if the two are at the same vertical angle, structural collision is likely to occur.
[0040] Extending this further, the first eccentric wheel 8 at one end of the first rotating tooth 5 and the second rotating tooth 7 can also be set in parallel, which can also prevent the structural components from moving normally. The diverter plate 10 and the transmission component are provided with a side plate placed inside the first housing 2, and the extension of the lower pressure plate 12 passes through the side plate and the connection is a telescopic sealing connection, that is, the lower pressure plate 12 can move normally, and the connection of the structural components can also maintain the corresponding sealing.
[0041] The diverter plates 10 are arranged in a ring array on both the movable shaft 4 and the first rotating shaft 9, and the movable shaft 4 and the first rotating shaft 9 rotate in opposite directions. The annular groove 18 is connected to the second rotating shaft 21 inside the cover 20 via the second conveyor belt 19. Both ends of the second rotating shaft 21 are fixedly installed with swing arms 22. One end of the swing arm 22 is connected to a spray pipe 23 placed above the diverter plate 10, and the other end is connected to a water storage box 24 placed on the outer wall of the first housing 2 via a conduit.
[0042] Both ends of the cover 20 are fixed to the side wall of the first housing 2 by crossbeams. The extension of the bottom end of the lower pressure plate 12 passes through the first housing 2 and extends to the mounting rod 25 on the side wall of the first housing 2. The upper pressure plate 11 and the lower pressure plate 12 are connected to the sliding groove along the height direction of the side wall of the first housing 2. The bottom of the mounting rod 25 is detachably mounted with a top rod 26 through a frame. Below the top rod 26 is a filter plate 27 fixed to the side wall of the first housing 2. The filter holes on the filter plate 27 are connected to the top rod 26. A cleaning chamber is formed between the filter plate 27 and the bottom of the inner wall of the first housing 2. The opening on the cleaning chamber is connected to a water storage box 24 through a circulation pump on a conduit.
[0043] During the up-and-down movement of the lower pressure plate 12, the bending rod can drive the synchronous movement of the mounting rod 25. During the movement, the mounting rod 25 can pass back and forth through the filter holes on the filter plate 27 via the top rod 26. This not only prevents the filter plate 27 from clogging during operation, but also ensures the normal purification and filtration work of the filter plate 27. At the same time, the filter plate 27 adopts a pull-out movable structure design, which can effectively clean the impurities on the filter plate 27, making it easy for personnel to operate. The filtered water can enter the water storage box 24 through the circulation pump for secondary use, which has good environmental protection effect and strong application performance.
[0044] Specifically, during long-term use, the filter holes on the filter plate 27 may become clogged. The push rod 26 can effectively remove impurities during the pushing process, thus facilitating the stable filtration and cleaning of the filter plate 27 itself.
[0045] The fresh vegetable cleaning machine with cleaning function also includes a second cleaning mechanism 28. The second cleaning mechanism 28 includes a second motor 30 placed on the second housing 29. The output shaft of the second motor 30 extends to the reciprocating screw 31. A second eccentric wheel 32 and a first bevel gear 33 are fixedly connected to the outer wall of the reciprocating screw 31. Both ends of the reciprocating screw 31 are helically driven with sliders 34 that move in the same direction. One end of the slider 34 passes through the second housing 29 and extends to the outer wall of the moving box 35. The top of the moving box 35 is provided with a feeding port, and the moving box 35 is provided with cleaning holes 36 that are adapted to it on all four sides.
[0046] The outer wall of the first bevel gear 33 meshes with the second bevel gear 38, which is fixed on the third rotating shaft 37. The third rotating shaft 37 is connected to a stirring rod 39 that extends to the inner wall of the movable box 35. The outer wall of the movable box 35 is provided with a strip groove 40 that connects to the third rotating shaft 37. Both ends of the movable box 35 are connected to the side wall of the second housing 29 by a telescopic rod 41. The top of the second eccentric wheel 32 moves against the push rod 42.
[0047] The top of the push rod 42 is connected to the extrusion plate 43, which is placed above the moving box 35, via a bending rod. The top of the extrusion plate 43 is connected to an extension end placed on the side wall of the moving box 35 via a second spring 44. The outer wall of the second housing 29 has an opening for connecting to the bending rod. The opening is a telescopic sealing structure design.
[0048] The second cleaning mechanism 28 can perform a secondary cleaning of the vegetables. First, the pre-cleaned vegetables are placed into the movable box 35. The second motor 30 starts and drives the reciprocating screw 31, the second eccentric wheel 32, and the first bevel gear 33 to rotate synchronously. Under the action of the screw drive, the slider 34 drives the movable box 35 to reciprocate horizontally within the second housing 29. Under the action of gear meshing, the first bevel gear 33 drives the stirring rod 39 on the third rotating shaft 37 to rotate inside the movable box 35. Because the movable box 35 has a slot 40, combined with the horizontal movement of the movable box 35 itself, this allows the stirring rod to rotate more effectively. During rotation, the stirring rod 39 stirs and cleans the vegetables at various positions in the water, while ensuring the normal movement of the moving box 35. During rotation, the second eccentric wheel 32, in conjunction with the pressing plate 43 on the second spring 44, can transmit the rotational motion of the second eccentric wheel 32 to the pressing plate 43 through the push rod 42, causing the pressing plate 43 to move up and down. This can squeeze the vegetables floating on the water surface into the water, thus effectively contacting the water and the stirring rod 39, further improving the cleaning effect. The vegetables are cleaned thoroughly, facilitating subsequent processing and packaging, and improving the stability of the cleaning machine.
[0049] In addition, an ultrasonic generator 45 is provided below the mobile box 35 and placed at the bottom of the inner wall of the second housing 29. An active cavity is formed between the side wall of the second housing 29 and the mobile box 35. The top of the extrusion plate 43 is triangular or trapezoidal. The shape of the extrusion plate 43 can effectively prevent vegetables from being placed on the top of the extrusion plate 43. The vegetables can automatically slide into the mobile box 35 by their own gravity, which facilitates the corresponding cleaning work.
[0050] A conveyor line 46 is provided between the first cleaning mechanism 1 and the second cleaning mechanism 28. The conveyor line 46 is installed on the base plate and extends along a preset direction to carry and transport vegetables. The conveyor line 46 is not only the connecting medium between the first cleaning mechanism 1 and the second cleaning mechanism 28, but also can stably transport the vegetables after primary cleaning to the second cleaning mechanism 28 for secondary cleaning.
