Description

Technical Field

[0001] This invention belongs to the field of vegetable cleaning technology, specifically a cleaning device for processing fresh corn. Background Technology

[0002] Fresh corn is a starchy vegetable. The fresh corn processing and cleaning equipment adopts an integrated production line design and is equipped with a cleaning system. First, a powerful fan and vibrating screen remove surface impurities and corn silk. Then, the corn enters a high-pressure spray chamber, where multi-angle rotating nozzles thoroughly rinse it with food-grade water. At the same time, brush rollers gently rub the surface to effectively remove dirt from crevices. After rinsing, the corn is dried in a drying channel and then discharged. The entire process is automated, highly efficient, and energy-saving, and is specially designed for fresh corn processing.

[0003] A patent application with publication number CN117427703A discloses a spray cleaning device for processing micro-corn, including a box-shaped processing frame. Several spray pipes are embedded between the top of the left and right sides of the processing frame. A water pump and a water supply tank are installed on one side of the processing frame. A de-hulling group for peeling and de-silking micro-corn is set in the bottom port of the processing frame. This application can drive the de-hulling rod to rotate relative to each other to clamp the corn, and use a pick to grind off the husk and silk. Then, the corn is rinsed by high-speed spraying of water mist from the spray pipes. It can automatically and quickly peel and clean the corn.

[0004] When cleaning starchy vegetables like fresh corn, the aforementioned corn washing device can remove the husks and silks from the corn using a desiccant bar and a high-speed water mist sprayer. However, traditional fresh corn washing devices typically place the corn on a filter plate for cleaning. Due to the flat design of the filter plate, some parts of the fresh corn, especially the bottom and sides, are difficult to come into contact with the water flow. This cleaning method makes it difficult to clean multiple parts of the fresh corn thoroughly, which can easily affect the cleaning effect.

[0005] Therefore, the present invention provides a cleaning device for processing fresh corn. Summary of the Invention

[0012] Preferably, a fixing block is fixedly connected to the outside of the water sprayer; a double-threaded screw is rotatably connected to the fixing block, and the double threads on the double-threaded screw are arranged in opposite directions; two sliding plates are slidably connected to the water sprayer, and the two sliding plates are respectively threadedly connected to the double-threaded screw; a connecting frame is fixedly connected to the sliding plate by bolts; a partition plate is fixedly connected to the bottom end of the connecting frame.

[0013] Preferably, the water sprayer is equipped with multiple water pipe switches; a squeezing plate is fixedly connected to the sliding plate, and the squeezing plate slides on the water sprayer.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a fresh corn processing and cleaning device. The corn is cleaned by rotating between two rotating rods. After cleaning, it can be dried and unloaded. This cleaning method replaces traditional equipment using flat filter plates, reducing the difficulty of cleaning certain parts of the fresh corn with water flow, and improving the cleaning effect on starchy vegetables like fresh corn. During the cleaning process, the high-pressure nozzles spray a strong and uniform water flow that penetrates deep into the crevices of the corn, washing away residual impurities, dirt, and potential pesticide residues. Simultaneously, because the corn rotates between the two rotating rods, the cleaning is more comprehensive, reducing blind spots and improving the quality and efficiency of the cleaning. After cleaning, the equipment can be equipped with… Equipped with appropriate drying devices, the washed corn is quickly dried. The dried corn can then be directly unloaded and packaged for subsequent processing and sales. The entire process is seamless and efficient, greatly improving the overall efficiency of fresh corn processing. Simultaneously, this starchy vegetable and fresh corn processing and cleaning equipment uses a rolling feeding method, allowing the fresh corn to roll multiple times between two rotating rods before being sent for washing. This facilitates the removal of impurities from the corn. During the rolling process, dirt, shavings, and other impurities on the corn surface gradually separate under the combined action of centrifugal force and friction, further enhancing the initial cleaning effect. This pretreatment mechanism not only reduces the burden on subsequent high-pressure washing but also lowers water consumption.

[0018] 2. The fresh corn processing and cleaning equipment of this invention, through the rotation of two sliding plates with a double-threaded screw, moves closer or further apart, synchronously causing the partition plates connected to two connecting frames to move closer or further apart, thereby adjusting the width of the corn cleaning channel. The channel width can be flexibly adjusted according to the different sizes of fresh corn, ensuring the corn is in an optimal space during the cleaning process and guaranteeing the best cleaning effect. When dealing with smaller corn particles, controlling the rotation of the double-threaded screw causes the two sliding plates to move closer together, which in turn causes the partition plates to move closer together, narrowing the width of the cleaning channel. The corn is thoroughly and completely cleaned within a relatively compact space, preventing it from rolling around during the cleaning process due to an excessively wide channel, which would affect the uniformity of the cleaning. For larger corn kernels, the double-threaded screw is operated in reverse, causing the two sliding plates to move away from each other, which in turn moves the partition plates away from each other, widening the cleaning channel. This ensures that larger corn kernels can pass through smoothly and be thoroughly cleaned in the spacious channel, reducing the risk of compression and incomplete cleaning caused by a narrow channel. This adjustable cleaning channel width design enhances the adaptability and versatility of this fresh corn processing and cleaning equipment for corn of different sizes, further improving the practicality of the equipment.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3 As shown in the embodiment of the present invention, a fresh corn processing and cleaning device includes a base 1; three transmission rollers 11 are rotatably connected to the base 1; connecting belts 12 are sleeved at both ends of the three transmission rollers 11; multiple rotating rods 13 are rotatably connected between two of the connecting belts 12; a servo motor 14 is fixedly connected to the base 1, and one transmission roller 11 is fixedly connected to the output end of the servo motor 14; a fixing plate 15 is fixedly connected to the base 1; a friction belt 16 is fixedly connected to the fixing plate 15, and the friction belt 16 is in contact with the surface of the multiple rotating rods 13; A water sprayer 17 is fixedly connected to the base 1, and multiple high-pressure nozzles are fixedly connected to the bottom of the water sprayer 17. When cleaning starchy vegetables and fresh corn, the base 1 serves as the main structure of the starchy vegetable and fresh corn processing and cleaning equipment. Three drive rollers 11 are fixed to the base 1 for mounting two connecting belts 12. Multiple rotating rods 13 are installed between the two connecting belts 12. Every two fixed plates 15 fix a friction belt 16 to the surface of the base 1 near the multiple rotating rods 13 and fits them together, so that friction belts 16 are installed on both sides of the drive rollers 11. First, the peeling... Starchy vegetables and fresh corn cobs are laid on multiple rotating rods 13, located at the end of the machine base 1 closest to the servo motor 14. At this time, the output end of the servo motor 14 drives a transmission roller 11 to rotate. The three transmission rollers 11 connected by the connecting belt 12 rotate synchronously. Each corn cob lies between two rotating rods 13. As the connecting belt 12 drives the multiple rotating rods 13 to move, because two friction belts 16 are fixed to the machine base 1 with multiple fixing plates 15, the multiple rotating rods 13 that are moving are rubbed against the surfaces of the two friction belts 16 and the multiple rotating rods 13. As the corn rotates, the corn between the two rotating rods 13 also rotates. Surface particles made of edible silicone can be added to the rotating rods 13 to enhance friction until the corn is sent to the bottom of the water sprayer 17. The water sprayer 17 is connected to an external water source and continuously cleans the corn through multiple high-pressure nozzles. The corn rotates and is cleaned between the two rotating rods 13. After cleaning, it can be dried and discharged. This cleaning method replaces the traditional equipment for cleaning on a flat filter plate, reducing the difficulty of certain parts of fresh corn coming into contact with water for cleaning, and improving the cleaning effect on starchy vegetables and fresh corn. During the cleaning process, the high-pressure nozzles spray a powerful and even stream of water that penetrates deep into every crevice of the corn, washing away residual impurities, dirt, and any pesticide residues. Simultaneously, the rotation of the corn between the two rotating rods 13 ensures a more thorough cleaning, reducing blind spots and improving both quality and efficiency. After cleaning, the equipment can be equipped with a drying device for rapid drying of the corn. The dried corn can then be directly unloaded, packaged, and used for subsequent processing and sales. The entire process is seamless and efficient, significantly improving the overall efficiency of fresh corn processing. Meanwhile, the starchy vegetable and fresh corn processing and cleaning equipment adopts a rolling feeding method, which allows the fresh corn to roll multiple times between the two rotating rods 13 before being sent to the washing stage. This makes it easier for impurities on the corn to fall off. During the rolling process, dirt, skin, and other impurities on the surface of the corn will gradually separate under the combined action of centrifugal force and friction, further improving the initial cleaning effect. This pretreatment mechanism not only reduces the burden of subsequent high-pressure washing, but also reduces water consumption.

[0024] A first baffle plate 2 is fixedly attached to the base 1 near the servo motor 14; a second baffle plate 21 is fixedly attached to the base 1 near the first baffle plate 2, with the bottom surface of the first baffle plate 2 being higher than that of the second baffle plate 21. When cleaning vegetables and corn, several ears of corn are first poured between the first baffle plate 2 and the second baffle plate 21. The first baffle plate 2, with a hook-shaped cross-section, is positioned at the front end of the second baffle plate 21 to block the flow. The vegetables and corn fall between the two rotating rods 13 and pass through the bottom of the first baffle plate 2. This design, where the bottom surface of the first baffle plate 2 is higher than that of the second baffle plate 21, effectively reduces [the impact of the baffle plate 2's height on the cleaning process]. During the pouring process, the corn rolls off the equipment, effectively guiding and limiting its movement. The hook-shaped No. 1 baffle plate 2, with its unique shape, better conforms to the shape of the corn, providing cushioning and guidance during pouring, allowing the corn to fall more smoothly between the two rotating rods 13 for subsequent cleaning operations. Moreover, this simple design significantly improves the accuracy and efficiency of the equipment's feeding process in actual use, reduces waste and extra workload caused by corn rolling off, and mitigates the issue of poor cleaning in areas where fresh corn accumulates, further ensuring the smooth operation of the entire fresh corn processing and cleaning process.

[0025] A feeding roller 3 is rotatably connected to the base 1, and the feeding roller 3 has three U-shaped grooves. A first gear set is installed inside the base 1, and the transmission roller 11 near the servo motor 14 can be connected to the feeding roller 3 through the first gear set. When the vegetables and corn are fed, a large amount of corn is poured into the container composed of the first baffle plate 2 and the second baffle plate 21. The output end of the servo motor 14 drives the nearby transmission roller 11 to rotate. The transmission roller 11 drives the feeding roller 3 to rotate synchronously through the first gear set. The corn falls into the U-shaped groove as the feeding roller 3 rotates, allowing the corn to correct its orientation in advance. Then, the corn in the U-shaped groove rotates and falls close to the two rotating rods 13. This process ensures that the corn falls between the two rotating rods 13 in a relatively uniform and appropriate posture, avoiding the situation where the corn rolls randomly and causes a messy posture, which affects the subsequent cleaning effect. The rotation speed of the feeding roller 3 and the rotation speed of the transmission roller 11 are precisely matched through the first gear set, so that the feeding rhythm of the corn is stable and orderly, reducing the phenomenon of corn accumulation and insufficient supply. Moreover, the design dimensions of the U-shaped trough can accommodate fresh corn of different sizes. Whether the corn kernels are small or large, they can be well corrected and guided within the U-shaped trough. At the same time, the surface of the U-shaped trough is smoothed, which reduces damage to the surface of the corn during the process of falling and rotating, thus ensuring the integrity and quality of the corn. Once the corn falls from the U-shaped trough between the two rotating rods 13, the subsequent cleaning process can proceed efficiently and smoothly. This corn orientation correction mechanism, achieved through the feeding roller 3 and the U-shaped trough, provides a strong guarantee for the efficient operation of the entire fresh corn processing and cleaning equipment, further enhancing the equipment's processing and cleaning capabilities for fresh vegetables and corn, as well as its overall performance.

[0026] like Figures 1 to 4As shown, a water pump 4 is fixedly connected to the base 1 near the sprayer 17, and the output end of the water pump 4 is connected to the sprayer 17; a filter screen plate 41 is fixedly connected inside the base 1, and the input end of the water pump 4 is located below the filter screen plate 41; when rinsing vegetables and corn, the water pump 4 is fixed to one side of the base 1, and the high-pressure nozzle at the top of the sprayer 17 continuously sprays water to rinse the corn. The rinsed water falls onto the filter screen plate 41 to filter impurities and corn silk on the corn. The filtered water is stored inside the base 1, and then the water pump 4 draws the stored water through the input end and sends it back to the sprayer 17 through its output end for circulating spraying, which saves water resources; This water circulation system not only reduces water waste but also lowers processing costs. In actual operation, the filtration effect of the filter screen 41 is crucial. It can effectively intercept impurities and corn silk that fall off during corn washing, ensuring that the water returned to the water sprayer 17 is relatively clean and reducing secondary pollution of the corn. When the amount of water stored inside the machine base 1 and the cleanliness of the water are lower than the standard, new water needs to be added to ensure the normal operation of the water circulation system and the cleaning quality. This water recycling mechanism enables the entire fresh corn processing and cleaning equipment to maximize the utilization of water resources while cleaning efficiently, thereby improving the overall performance and market competitiveness of the equipment.

[0027] Two guide plates 5 are fixed to the bottom end of the filter screen plate 41. The two guide plates 5 are arranged opposite each other and are inclined. When the water sprayed from the water sprayer 17 to wash the corn, the washed water falls onto the filter screen plate 41 for filtration. The two guide plates 5 are fixed at the bottom of the filter screen plate 41 with their relative positions and inclinations, so that the accumulated water is guided to the input end of the water pump 4 for temporary storage. The two inclined guide plates 5 can ensure the smooth convergence of water flow and ensure that the filtered water can be quickly pumped back by the water pump 4. The relative arrangement of the two guide plates 5 also forms a natural flow channel, which further optimizes the efficiency of the water circulation system.

[0028] like Figures 1 to 5As shown, a fixing block 6 is fixedly connected to the outside of the water sprayer 17; a double-threaded screw 61 is rotatably connected to the fixing block 6, and the double threads on the double-threaded screw 61 are arranged in opposite directions; two sliding plates 62 are slidably connected to the water sprayer 17, and the two sliding plates 62 are respectively threadedly connected to the double-threaded screw 61; a connecting frame 63 is fixedly connected to the sliding plate 62 by bolts; a partition plate 64 is fixedly connected to the bottom end of the connecting frame 63; when fresh vegetables and corn are being cleaned, the double-threaded screw 61 rotates on the fixing block 6, and the two sliding plates 62 move closer or further apart as the double-threaded screw 61 rotates, synchronously driving the partition plates 64 connected to the two connecting frames 63 to move closer or further apart, thereby adjusting the width of the corn cleaning channel. The channel width can be flexibly adjusted according to the different sizes of fresh corn, so that the corn can be in an optimal space during the cleaning process. The system ensures optimal cleaning results. When dealing with smaller corn kernels, the double-threaded screw 61 rotates, causing the two sliding plates 62 to move closer together, which in turn moves the partition plates 64 closer together, narrowing the cleaning channel width. This allows the corn to be thoroughly and completely cleaned within a relatively compact space, preventing it from rolling around during cleaning due to an excessively wide channel, thus ensuring uniform cleaning. For larger corn kernels, the double-threaded screw 61 is operated in the opposite direction, causing the two sliding plates 62 to move further apart, which in turn moves the partition plates 64 further apart, widening the cleaning channel width. This ensures that larger corn kernels can pass through smoothly and be thoroughly cleaned in the spacious channel, reducing the risk of compression and incomplete cleaning caused by a narrow channel. This adjustable cleaning channel width design enhances the adaptability and versatility of the fresh corn processing and cleaning equipment for different corn sizes, further improving the equipment's practicality.

[0029] Multiple water pipe switches 7 are installed on the water sprayer 17; a squeezing plate 71 is fixedly connected to the sliding plate 62, and the squeezing plate 71 slides on the water sprayer 17; when washing vegetables and corn of different sizes, multiple water pipe switches 7 are installed at the bottom of the water sprayer 17, and each water pipe switch 7 can control a row of high-pressure nozzles to open and close. When the two partition plates 64 approach each other, the sliding plate 62 can drive the squeezing plate 71 to slide synchronously. During the sliding process, the squeezing plate 71 can squeeze the water pipe switch 7 at one end of the arc, pressing the water pipe switch 7 into the interior of the water sprayer 17. Then, the water pipe switch 7 that is pressed in closes off the spray of the row of high-pressure nozzles it controls. When the two partition plates 64 move away from each other, the squeezing plate 7... As a result, switch 1 slides away from squeezing the water pipe switch 7. Switch 7 then pops out under the action of its internal spring and other reset structures, restarting the controlled row of high-pressure nozzles. While adjusting the width of the cleaning channel, it can automatically control the switching of the corresponding high-pressure nozzles based on changes in channel width, ensuring that the spray range of the high-pressure nozzles always matches the width of the cleaning channel. This guarantees that the corn receives a uniform and appropriate water flow impact during the washing process, regardless of changes in channel width. This further improves the accuracy and effectiveness of the washing process, preventing situations where the water flow is too strong or too weak in some areas due to changes in channel width. It also enhances the flexibility and adaptability of the equipment for washing different sizes of vegetables and corn.

[0030] A drying air box 8 is fixedly connected to the base 1, and the drying air box 8 has a built-in heating wire; air ducts 81 are fixedly connected to both sides of the drying air box 8; a fan blade rod 82 is rotatably connected to the drying air box 8, and multiple fan blades are fixedly connected to the fan blade rod 82; a first wheel 83 is fixedly connected to the fan blade rod 82; a connecting rod 84 is fixedly connected to one end of a transmission roller 11; a second wheel 85 is fixedly connected to the connecting rod 84, and the first wheel 83 and the second wheel 85 are connected by a belt; when drying the washed corn, the drying air box 8 is fixed to the base 1 and located at the rear end of the water sprayer 17. The output end of the servo motor 14 drives one transmission roller 11 to rotate, and the three transmission rollers 11 connected by the connecting belt 12 rotate synchronously. The transmission roller 11 closest to the drying air box 8 drives the second wheel 85 to rotate through the connecting rod 84, and the second wheel 85 drives the belt to rotate. As the first rotating disc 83 and fan blade rod 82 rotate, multiple fan blades on the fan blade rod 82 send air into the drying air box 8 through two air ducts 81. The heating wire generates heat, which, combined with the rotation of the multiple fan blades, blows hot air onto the corn being transported, allowing the moisture on the surface of the corn to evaporate quickly, achieving a rapid drying effect. This hot air drying method is not only highly efficient but also evenly distributes heat to all parts of the corn, avoiding problems such as localized overheating and insufficient drying. At the same time, the power of the heating wire can be adjusted according to actual needs to adapt to the drying requirements under different humidity and temperature conditions, ensuring that the corn maintains its original quality and taste during the drying process. In addition, the rotation speed of the fan blade rod 82 can also be precisely controlled by changing the model of the first rotating disc 83 and the second rotating disc 85, further optimizing the drying effect of vegetables and corn.

[0031] A DC air box 9 is fixedly connected to the drying air box 8, and the DC air box 9 is located between the water sprayer 17 and the drying air box 8; a connecting plate 91 is fixedly connected to one end of the partition plate 64 near the drying air box 8; a baffle 92 is fixedly connected to one end of the connecting plate 91, and the baffle 92 is slidably connected to the bottom of the DC air box 9; when drying the washed vegetables and corn, the fan blade rod 82 drives multiple fan blades to rotate and send air into the interior of the drying air box 8. Part of the air is guided through the drying air box 8 and sent to the DC air box 9 for discharge. The air at the DC air box 9 is stronger than the air at the bottom of the drying air box 8, but no heating wire is installed at the DC air box 9. Therefore, the strong air blown out by the DC air box 9 is used to blow off the water droplets remaining on the surface of the corn after washing, while the hot air blown out from the bottom of the drying air box 8... This is used for deep drying of corn. The two processes work together to form a complete process of first blowing off water droplets and then deep drying, which greatly improves drying efficiency and quality. By utilizing the different effects of wind, it avoids the problem that residual moisture may affect the drying effect of simple hot air drying, and also reduces the situation where strong winds directly blow on the corn, making it difficult to dry. At the same time, the baffle 92, together with the connecting plate 91, is slidably connected to the bottom of the DC air box 9 along with the partition plate 64. The position of the baffle 92 can be flexibly adjusted according to the width of the cleaning channel adjusted by the two partition plates 64, thereby changing the blowing range of the strong wind at the DC air box 9, ensuring that the water droplets remaining on the surface of the corn can be blown off comprehensively and accurately, further improving the accuracy and flexibility of drying.

[0032] like Figures 1 to 3 As shown, multiple cutting rollers 93 are rotatably connected to the lower part of the base 1 near the drying air box 8, and multiple cutters are fixed to the cutting rollers 93; a second gear set is provided inside the base 1, and the cutting rollers 93 can be connected to the transmission roller 11 near the drying air box 8 through the second gear set; when the vegetables and corn are washed and dried on the cleaning equipment, the corn silk that falls off the corn easily gets tangled on the multiple rotating rods 13. Multiple cutting rollers 93 are assembled below the drying air box 8, and the multiple cutting rollers 93 are connected to the transmission roller 11 through the second gear set. During the rotation of the transmission roller 11, the multiple cutting rollers 93 are synchronously driven to rotate. The cutters on the cutting rollers 93 are connected to the rotating rods 13. 3. Surface adhesion: The cutter squeezes and cuts the corn silk wrapped around the rotating rod 13, cutting off the tangled corn silk in time. The corn silk dried at the drying air box 8 is easier to cut, reducing the risk of the rotating rod 13 being obstructed due to continuous tangling of corn silk, which would affect the normal operation of the entire cleaning process. This cutter design utilizes the existing power source of the equipment, eliminating the need for an additional drive device, thus reducing the complexity and manufacturing cost of the equipment. Moreover, the cutting action of the cutter is synchronized with the cleaning and drying processes, realizing the integration and efficiency of the equipment functions. While ensuring the cleaning and drying effect, it effectively solves the common problem of corn silk tangling, further improving the stability and reliability of the equipment.

[0033] Working process: When cleaning starchy vegetables and fresh corn, the machine base 1 serves as the main structure of the starchy vegetable and fresh corn processing and cleaning equipment. Three drive rollers 11 are fixed on the machine base 1 to assemble two connecting belts 12. Multiple rotating rods 13 are installed between the two connecting belts 12. Every two fixing plates 15 fix a friction belt 16 to the surface of the machine base 1 near the multiple rotating rods 13 and make them fit together, so that friction belts 16 are installed on both sides of the drive rollers 11. First, the peeled starchy vegetables and fresh corn cobs are poured onto the multiple rotating rods 13, located at the end of the machine base 1 near the servo motor 14. At this time, the output end of the servo motor 14 drives a drive roller. Roller 11 rotates, and three drive rollers 11 connected by connecting belt 12 rotate synchronously. Each ear of corn lies between two rotating rods 13. As the connecting belt 12 drives multiple rotating rods 13 to move, the two friction belts 16, together with multiple fixing plates 15, are fixed to the machine base 1. This causes the multiple rotating rods 13, which are moving, to rub against the surfaces of the two friction belts 16 and rotate. The corn between the two rotating rods 13 can also rotate accordingly. Surface particles made of edible silicone can be added to the rotating rods 13 to enhance friction until the corn is delivered to the area below the water sprayer 17. The water sprayer 17 is connected to an external water source and continuously cleans the corn through multiple high-pressure nozzles. The corn is rotated and washed between two rotating rods 13. After washing, it can be dried and discharged. This washing method replaces the traditional equipment for washing on a flat filter plate, reducing the difficulty of certain parts of fresh corn coming into contact with water for cleaning, and improving the cleaning effect on starchy vegetables and fresh corn. When cleaning the vegetables and corn, several ears of corn are first poured between the first barrier plate 2 and the second barrier plate 21. The first barrier plate 2, with a hook-shaped cross-section, is located at the front end of the second barrier plate 21 to block the flow. The vegetables and corn fall between the two rotating rods 13 and pass through the bottom of the first barrier plate 2. The bottom surface of the first barrier plate 2 is higher than the bottom surface of the second barrier plate 21. The design effectively reduces corn rolling off the equipment during the pouring process, providing excellent guidance and limiting. The hook-shaped No. 1 baffle plate 2 has a special shape that better conforms to the shape of the corn, providing cushioning and guidance when the corn is poured in, allowing the corn to fall more smoothly between the two rotating rods 13 for subsequent cleaning operations. Moreover, this simple design significantly improves the accuracy and efficiency of the equipment's feeding in actual use, reduces waste and extra workload caused by corn rolling, and reduces the situation where the cleaning effect is poor in some areas where fresh corn is piled up, further ensuring the smooth progress of the entire fresh corn processing and cleaning process.When the vegetables and corn are being fed, a large amount of corn is poured into the container composed of the first baffle plate 2 and the second baffle plate 21. The output end of the servo motor 14 drives the nearby transmission roller 11 to rotate. The transmission roller 11 synchronously drives the feeding roller 3 to rotate through the first gear set. The corn falls into the U-shaped groove as the feeding roller 3 rotates, allowing the corn to correct its orientation in advance. Then, the corn in the U-shaped groove rotates and falls closer to the two rotating rods 13. This process ensures that the corn falls between the two rotating rods 13 in a relatively uniform and appropriate posture, avoiding the situation where the corn rolls randomly and causes a messy posture, which would affect the subsequent cleaning effect. The rotation speed of the feeding roller 3 and the rotation speed of the transmission roller 11 are precisely matched through the first gear set, so that the feeding rhythm of the corn is stable and orderly, reducing the phenomenon of corn accumulation and insufficient supply. When rinsing vegetables and corn, the water pump 4 is fixed to one side of the machine base 1, and the high-pressure nozzle on the top of the sprayer 17 continuously sprays water to rinse the corn. The rinsed water falls onto the filter screen 41 to filter impurities and corn silk from the corn. The filtered water is stored inside the machine base 1. Then, the water pump 4 draws the stored water through its input end and sends it back to the sprayer 17 for circulation spraying, which saves water resources. This water circulation system not only reduces water waste but also lowers processing costs. In actual operation, the filtration effect of the filter screen 41 is crucial. It can effectively intercept impurities and corn silk that fall during the corn rinsing process, ensuring that the water returned to the sprayer 17 is relatively clean and reducing secondary pollution of the corn. When the amount of water stored inside the machine base 1 and the cleanliness of the water are lower than the standard, new water needs to be added to ensure the normal operation of the water circulation system and the cleaning quality. This water recycling mechanism enables the entire fresh corn processing and cleaning equipment to maximize the utilization of water resources while cleaning efficiently, thereby improving the overall performance and market competitiveness of the equipment. When the water sprayed from the water sprayer 17 to wash the corn, the washed water falls onto the filter screen 41 for filtration. The two guide plates 5 are fixed at the bottom of the filter screen 41 with their relative angles, so that the accumulated water is guided to the input end of the water pump 4 for temporary storage. The two inclined guide plates 5 can ensure the smooth convergence of the water flow, ensuring that the filtered water can be quickly pumped back by the water pump 4. The relative arrangement of the two guide plates 5 also forms a natural flow channel, further optimizing the efficiency of the water circulation system. When fresh vegetables and corn are being cleaned, the double-threaded screw 61 rotates on the fixed block 6, causing the two sliding plates 62 to move closer or further apart. This synchronously moves the partition plates 64 connected to the two connecting frames 63 closer or further apart, thus adjusting the width of the corn cleaning channel. The channel width can be flexibly adjusted according to the different sizes of fresh corn, ensuring the corn is in an optimal space during cleaning and achieving the best cleaning effect. When dealing with smaller corn kernels, controlling the rotation of the double-threaded screw 61 causes the two sliding plates 62 to move closer together, which in turn moves the partition plates 64. By moving the two sliding plates closer together and narrowing the cleaning channel, the corn can be thoroughly and completely cleaned within a relatively compact space. This prevents the corn from rolling around during the cleaning process due to an excessively wide channel, which would affect the uniformity of the cleaning. For larger corn kernels, the double-threaded screw 61 is operated in reverse, causing the two sliding plates 62 to move away from each other, which in turn moves the partition plates 64 away from each other, widening the cleaning channel. This ensures that larger corn kernels can pass through smoothly and be thoroughly cleaned in the spacious channel, reducing the risk of compression and incomplete cleaning caused by a narrow channel. This adjustable cleaning channel width design enhances the adaptability of this fresh corn processing and cleaning equipment to corn of different sizes. The improved versatility and adaptability further enhance the equipment's practicality. When washing vegetables and corn of different sizes, multiple water pipe switches 7 are installed at the bottom of the sprayer 17. Each water pipe switch 7 can control a row of high-pressure nozzles. When the two partition plates 64 approach each other, the sliding plate 62 drives the squeezing plate 71 to slide synchronously. During the sliding process, the squeezing plate 71 squeezes the water pipe switch 7 at one end of the arc, pressing the water pipe switch 7 into the interior of the sprayer 17. Subsequently, the squeezed water pipe switch 7 shuts off the spray of the row of high-pressure nozzles it controls. When the two partition plates 64 move away from each other, the squeezing plate 71 also slides and moves away from squeezing the water pipe switch 7. The pressure and water pipe switch 7 pops out under the action of the internal spring and other reset structure, restarting the controlled row of high-pressure nozzles to spray; while adjusting the width of the cleaning channel, it can automatically control the switch of the corresponding high-pressure nozzles according to the change of the channel width, so that the spray range of the high-pressure nozzles always matches the width of the cleaning channel. This ensures that the corn receives a uniform and appropriate water flow impact during the washing process, regardless of the change in channel width, further improving the accuracy and effect of the washing, avoiding the situation where the water flow is too strong or too weak in some areas due to changes in channel width, and improving the flexibility and adaptability of the equipment for washing different sizes of vegetables and corn; When drying the washed corn, a drying air box 8 is fixed on the machine base 1 and located at the rear end of the water sprayer 17. The output end of the servo motor 14 drives a transmission roller 11 to rotate. The three transmission rollers 11 connected by the connecting belt 12 rotate synchronously. The transmission roller 11 closest to the drying air box 8 drives the second wheel 85 to rotate through the connecting rod 84. The second wheel 85 then drives the first wheel 83 connected by the belt and the fan blade rod 82 to rotate. The multiple fan blades on the fan blade rod 82 then send air into the drying air box 8 through two air ducts 81. The heating wire works to generate heat, which, together with the rotation of the multiple fan blades, blows the hot air to the conveyed area. The hot air drying process allows the surface moisture of the corn to evaporate quickly, achieving rapid drying. This method is not only highly efficient but also distributes heat evenly to all parts of the corn, avoiding localized overheating and insufficient drying. Furthermore, the power of the heating element can be adjusted to meet varying humidity and temperature conditions, ensuring the corn retains its original quality and texture during drying. Additionally, the rotation speed of the fan blade 82 can be precisely controlled by switching between the first and second discs 83 and 85, further optimizing the drying process for vegetable corn. The drying effect is achieved by using a fan blade rod 82 to rotate multiple fan blades and blow air into the drying box 8. Part of the air is directed through the drying box 8 to the DC air box 9 for discharge. The airflow at the DC air box 9 is stronger than that at the bottom of the drying box 8, but since no heating element is installed at the DC air box 9, the strong airflow from the DC air box 9 is used to blow off the water droplets remaining on the surface of the corn after washing. Meanwhile, the hot air blown from the bottom of the drying box 8 is used for deep drying of the corn. These two processes work together to form a complete process of first initially blowing off water droplets and then deep drying, greatly improving the drying efficiency. This improves drying efficiency and quality; by utilizing the different effects of wind, it avoids the problem of residual moisture affecting the drying effect that may occur with simple hot air drying, and also reduces the situation where strong winds directly blow on the corn, making it difficult to dry; at the same time, the baffle 92, together with the connecting plate 91, is slidably connected to the bottom of the DC air box 9 along with the partition plate 64. The position of the baffle 92 can be flexibly adjusted according to the width of the cleaning channel adjusted by the two partition plates 64, thereby changing the blowing range of the strong wind at the DC air box 9, ensuring that the residual water droplets on the surface of the corn can be blown off comprehensively and accurately, further improving the accuracy and flexibility of drying; When vegetables and corn are rinsed and dried on the cleaning equipment, the corn silk that falls off the corn easily gets tangled on the multiple rotating rods 13. Multiple cutting rollers 93 are mounted below the drying air box 8. These cutting rollers 93 are connected to the transmission roller 11 via a second gear set. As the transmission roller 11 rotates, it synchronously drives the multiple cutting rollers 93 to rotate as well. The cutters on the cutting rollers 93 are in contact with the surface of the rotating rods 13, squeezing and cutting the tangled corn silk. This timely cutting of the tangled corn silk makes it easier to cut the dried corn silk at the drying air box 8, reducing the risk of the corn silk continuously tangling and hindering the rotation of the rotating rods 13, thus preventing disruption to the entire cleaning process. This cutter design utilizes the existing power source of the equipment, eliminating the need for an additional drive unit, thus reducing the complexity and manufacturing cost of the equipment. Moreover, the cutting action of the cutter is synchronized with the cleaning and drying processes, achieving integrated and efficient equipment functionality. While ensuring the cleaning and drying effects, it effectively solves the common problem of corn silk tangling, further improving the stability and reliability of the equipment.
