Description

Technical Field

[0001] This application relates to the field of food processing machinery technology, and in particular to a nut washing machine. Background Technology

[0002] Nut washing removes surface impurities and potential risks, ensuring food safety and quality. Specifically, it removes dirt, dust, pesticide residues, and microorganisms that adhere to nuts during harvesting, processing, and storage, reducing the risk of gastrointestinal discomfort or infection; it also reduces mold spores and metabolites, which is particularly important for easily contaminated nuts such as peanuts and almonds. Simultaneously, washing improves taste, prevents impurities from affecting flavor, and extends shelf life. In processing settings, it provides a clean base for subsequent baking and seasoning processes, ensuring consistent product quality and serving as a crucial step in guaranteeing nutrition and safety.

[0003] Nut washing machines work by using water flow to impact and rub against the nuts to remove surface impurities, while simultaneously using a filtration system to separate contaminants. Applications include: bulk cleaning of raw nuts in food processing plants; small-scale nut processing in households; pre-processing of raw materials in bakeries; cleaning before removing moldy or broken nuts in nut processing enterprises; and secondary cleaning of bulk nuts in warehouses to ensure food safety and quality.

[0004] In existing technologies, some nut cleaning machines generally clean nuts by simply using water flow to wash them. This makes it difficult for the nuts to be rinsed by water from all directions, resulting in incomplete cleaning. The dirt and impurities remaining on the surface of the nuts will affect subsequent processing. Therefore, a nut cleaning machine is proposed. Utility Model Content

[0005] The purpose of this application is to provide a nut cleaning machine that aims to improve the problem that nuts are difficult to clean thoroughly due to the difficulty of receiving all-round water flow, resulting in residual dirt and impurities on the surface of the nuts, which can affect subsequent processing.

[0006] The nut washing machine provided in this application adopts the following technical solution: A nut washing machine includes a washing tank, a cleaning and screening mechanism is installed on the inner wall of the washing tank, a lifting machine is installed on one side of the washing tank, a drying plate is installed at the other end of the lifting machine, a drying mechanism is installed on both sides of the drying plate, and multiple water spray nozzles are fixedly connected to the inner wall of the washing tank.

[0007] The cleaning and screening mechanism includes a drive motor, the bottom of which is fixedly connected to the top of the cleaning tank. A rotating rod is fixedly connected to the drive end of the drive motor. A transmission rod is rotatably connected to one end of the rotating rod, and a connecting plate is rotatably connected to the other end of the transmission rod. A screen is slidably connected to the inner wall of the cleaning tank, and a cleaning component is installed on the top of the screen.

[0008] By adopting the above technical solution: the washing box provides a closed space for washing nuts; the cleaning and screening mechanism can realize the washing and screening of nuts; the elevator is used to transport the washed nuts to the drying plate; the drying mechanism dries the nuts on the drying plate; multiple water nozzles can spray water into the washing box from different angles to fully wet the nuts and wash away dirt, improving the initial cleaning effect; after the drive motor starts, it drives the rotating rod to rotate, and the rotating rod transmits power to the connecting plate through the transmission rod, so that the connecting plate drives the screen to reciprocate on the inner wall of the washing box. The nuts turn over on the screen surface, which is convenient for the water nozzles to wash them thoroughly. At the same time, bad nuts fall through the gaps in the screen due to weight or size differences, thus achieving screening; the cleaning component can further clean the surface of the nuts, improving the cleaning effect.

[0009] Preferably, the cleaning component includes a rotating motor, the drive end of which is fixedly connected to a central shaft, both ends of which are fixedly connected to a mounting bracket, and multiple cleaning brushes are fixedly connected to adjacent sides of the two mounting brackets.

[0010] By adopting the above technical solution: the rotating motor starts and drives the central shaft to rotate, and the central shaft drives multiple cleaning brushes to rotate through the fixed frame. The cleaning brushes come into contact with the surface of the turned nuts and can remove stubborn stains such as dirt and impurities from the surface of the nuts. Combined with the rinsing of the water nozzle, the cleaning cleanliness is further improved, ensuring that there are no residual stains on the surface of the nuts.

[0011] Preferably, the drying mechanism includes a mounting plate, the outer wall of which is fixedly connected to the side wall of the drying plate, an electric push rod is fixedly connected to the top of the mounting plate, a sliding rod is fixedly connected to the driving end of the electric push rod, and a slide rail is fixedly connected to the top of the mounting plate.

[0012] By adopting the above technical solution: the mounting plate provides installation support for the electric push rod and the slide rail. When the electric push rod is started, it can drive the sliding rod to slide on the top of the slide rail. The slide rail guides the movement of the sliding rod, ensuring the stability of the sliding rod's movement and providing a power basis for the subsequent swinging action of the drying mechanism.

[0013] Preferably, the bottom of the sliding rod is slidably connected to the top of the slide rail, and a rotating column is fixedly connected to the top of the sliding rod;

[0014] By adopting the above technical solution: the sliding rod slides stably on the top of the slide rail to avoid movement deviation, and the rotating column at the top of the sliding rod moves synchronously with the sliding rod. The rotating column can serve as a fulcrum for connecting with the L-shaped rod, converting the linear motion of the sliding rod into the rotational power of the L-shaped rod, thus realizing the transmission and conversion of force.

[0015] Preferably, an L-shaped rod is rotatably connected to the outer wall of the rotating column, a connecting column is rotatably connected to the inner wall of the L-shaped rod, and the bottom of the connecting column is rotatably connected to the inner wall of the drying plate.

[0016] By adopting the above technical solution: when the rotating column drives the L-shaped rod to move, since the middle part of the L-shaped rod is connected to the drying plate through the connecting column, the connecting column becomes the rotation fulcrum of the L-shaped rod, so that the L-shaped rod can swing around the connecting column as the center, converting the linear motion of the sliding rod into the reciprocating swing of the L-shaped rod, providing a motion trajectory for the swing of the air nozzle.

[0017] Preferably, an air nozzle is fixedly connected to the inner wall of the L-shaped rod, and multiple water leakage holes are opened on the inner wall of the drying plate.

[0018] By adopting the above technical solution: when the L-shaped rod swings, it drives the air nozzle to swing synchronously, so that the air nozzle can blow air evenly on the surface of the drying plate, thereby speeding up the drying speed. The drain hole can drain the water dripping from the surface of the nuts in time, avoiding water accumulation that affects the drying efficiency, and at the same time preventing the nuts from being soaked in water for a long time and thus spoiling.

[0019] Preferably, the drying plate has rotating grooves on both sides, and the bottom of the connecting column is rotatably connected to the inner wall of the rotating groove.

[0020] By adopting the above technical solution: the rotating groove provides rotation space for the connecting column, allowing the connecting column to rotate flexibly within the rotating groove, ensuring that the rotation of the connecting column is not hindered when the L-shaped rod swings, improving the smoothness of the air drying mechanism's movement, ensuring stable swing of the air nozzle, and thus uniformly drying the nuts.

[0021] Preferably, a receiving plate is fixedly connected to the top of the drive motor, and the bottom of the connecting plate is fixedly connected to the top of the screen.

[0022] By adopting the above technical solution: the receiving plate is used to receive the bad fruits screened out by the screen, which facilitates the centralized collection and processing of bad fruits. The bottom of the connecting plate is fixed to the top of the screen, so that the connecting plate can stably drive the screen to reciprocate, ensuring the stability of the screen during movement and ensuring the turning and screening effect of the nuts on the screen.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Place the nuts to be cleaned into the inner wall of the cleaning tank. The water nozzle sprays water onto the inner wall of the cleaning tank. The drive motor starts and drives the transmission rod to move. The movement of the transmission rod causes the connecting plate to move back and forth on the inner wall of the cleaning tank, which in turn causes the screen to move back and forth. This makes the nuts turn over on the surface of the screen, which improves the cleaning effect of the nuts and also filters out bad nuts to the surface of the receiving plate. When the nuts are on the surface of the screen, the rotating motor starts. The starting of the rotating motor drives the fixed frame to rotate. The rotation of the fixed frame allows the central shaft to clean the surface of the nuts and remove dirt and other stains, thus achieving a better and more complete cleaning of the nuts.

[0025] 2. When air drying is required, the electric push rod is activated to move the sliding rod at the top of the slide rail, causing one end of the L-shaped rod to rotate. Since the middle of the L-shaped rod is fixed inside by the connecting column, the connecting column can drive the air nozzle to swing back and forth, thereby blowing air evenly onto the nuts on the surface of the drying plate and accelerating the drying efficiency. The drainage holes on the surface of the drying plate facilitate the drainage of water from the surface of the nuts, so that the washed nuts can be dried quickly. Attached Figure Description

[0038] Reference Figures 2 to 4 The air-drying mechanism 3 includes a mounting plate 31, which provides a mounting base for other components of the air-drying mechanism 3. The outer wall of the mounting plate 31 is fixedly connected to the side wall of the air-drying plate 4 to make the mounting plate 31 stable and fixed. An electric push rod 32 is fixedly connected to the top of the mounting plate 31. The electric push rod 32 provides power for the sliding of the sliding rod 34.

The bottom of the sliding rod 34 is slidably connected to the top of the slide rail 33 so that the sliding rod 34 can slide smoothly along the slide rail 33.

[0039] Specifically, the drying mechanism 3 includes a mounting plate 31, which provides a mounting base for other components. The outer wall is fixed to the side wall of the drying plate 4 for stable fixation. The electric push rod 32 at the top of the mounting plate 31 provides power for the sliding rod 34 to slide. Its drive end is connected to the sliding rod 34, and its extension and retraction can drive the sliding rod 34 to move. The slide rail 33 at the top of the mounting plate 31 serves as a sliding guide for the sliding rod 34 to ensure directional stability. The bottom of the sliding rod 34 is slidably connected to the top of the slide rail 33, allowing it to slide smoothly along the slide rail 33.

[0040] A rotating column 36 is fixedly connected to the top of the sliding rod 34. The movement of the sliding rod 34 can drive the rotating column 36 to move synchronously. An L-shaped rod 35 is rotatably connected to the outer wall of the rotating column 36. The movement of the rotating column 36 can drive one end of the L-shaped rod 35 to rotate. A connecting column 37 is rotatably connected to the inner wall of the L-shaped rod 35. The connecting column 37 provides a fulcrum for the rotation of the L-shaped rod 35. The bottom of the connecting column 37 is rotatably connected to the inner wall of the drying plate 4, so that the position of the connecting column 37 is fixed. An air nozzle 38 is fixedly connected to the inner wall of the L-shaped rod 35. The rotation of the L-shaped rod 35 can drive the air nozzle 38 to swing, so as to achieve uniform blowing. Multiple drainage holes 5 are opened on the inner wall of the drying plate 4. The drainage holes 5 can drain the water dripping from the surface of the nuts to avoid water accumulation affecting the drying. Rotating grooves are opened on both sides of the drying plate 4. The rotating grooves provide rotation space for the connecting column 37. The bottom of the connecting column 37 is rotatably connected to the inner wall of the rotating groove, so that the connecting column 37 can rotate in the rotating groove.

[0041] Specifically, the rotating column 36 at the top of the sliding rod 34 moves synchronously with the sliding rod 34, and one end of the L-shaped rod 35 connected to its outer wall is driven to rotate. The connecting column 37 on the inner wall of the L-shaped rod 35 provides a fulcrum for rotation. The bottom of the connecting column 37 is fixed to the inner wall of the drying plate 4.

The rotating grooves on both sides provide rotation space for the connecting column 37, allowing the connecting column 37 to rotate in the groove. All components work together to complete the air blowing and drainage functions during the drying process.

[0042] Working principle: When it is necessary to clean the nuts, the nuts to be cleaned are placed on the inner wall of the cleaning tank 1. Water is then sprayed onto the inner wall of the cleaning tank 1 through the water nozzle 7. Then, the drive motor 21 is started, which drives the transmission rod 23 to move. The movement of the transmission rod 23 causes the connecting plate 24 to move back and forth on the inner wall of the cleaning tank 1. This causes the connecting plate 24 to move the top screen 27 back and forth, making the nuts turn over on the surface of the screen 27. This improves the cleaning effect of the nuts and also filters out bad nuts to the surface of the receiving plate 25. When the nuts are on the surface of the screen 27, the rotating motor 261 is started. The start of the rotating motor 261 drives the fixed frame 262 to rotate. The rotation of the fixed frame 262 allows the central shaft 263 to clean the surface of the nuts and remove dirt and other stains.

[0043] When air drying is required, the nuts are transported by the elevator 6 to the surface of the drying plate 4. First, the pipe outside the air nozzle 38 is connected to the air pump. Then, the electric push rod 32 is started, which drives the sliding rod 34 to move on the top of the slide rail 33, thereby causing one end of the L-shaped rod 35 to rotate. Since the middle part of the L-shaped rod 35 is fixed inside by the connecting column 37, the connecting column 37 can drive the air nozzle 38 to swing back and forth, thereby blowing air evenly on the nuts on the surface of the drying plate 4 and speeding up the drying efficiency. The drainage holes 5 opened on the surface of the drying plate 4 facilitate the drainage of water from the surface of the nuts.
