Description

Technical Field

[0001] This invention relates to the field of agricultural product cleaning equipment technology, specifically a vertical high-efficiency scallion cleaning device. Background Technology

[0002] Post-harvest cleaning of scallions mainly employs two methods: manual cleaning and mechanical cleaning. Manual cleaning, the traditional method, involves operators placing the scallions in a water tank and removing surface dirt and sand by hand-brushing, shaking, and rinsing. Mechanical cleaning primarily uses horizontal conveyor cleaning machines. This equipment typically consists of a frame, a horizontally positioned mesh belt conveyor, spray pipes above the mesh, and a water tank at the bottom. During cleaning, the scallions are laid flat on the horizontal conveyor belt and moved slowly with it. Several spray nozzles above continuously spray water, using the impact force of the water to wash away the dirt and impurities adhering to the scallion surface. The washed wastewater falls into the bottom water tank, undergoes simple sedimentation, and is then pumped out for recycling, thus achieving continuous cleaning. However, due to the horizontal conveyor structure, the scallions are not turned over during transport, and those at the bottom and inside are not effectively impacted by the water flow, resulting in incomplete cleaning. The fundamental reason is that the structural layout limits the cleaning range. Relying solely on the impact of water flow from top to bottom, it lacks effective mechanical turning and friction, resulting in limited ability to remove firmly adhered soil. During horizontal conveying, scallion leaves and white parts are easily entangled, pulled, and squeezed by the conveyor belt chains, rollers, or interfaces, causing mechanical damage, which impairs the product's appearance, reduces its commercial value, and is not conducive to subsequent storage. The horizontally extended conveyor belt structure dictates that the equipment must be very long in order to obtain sufficient cleaning time and throughput, thus occupying a large amount of floor space in the factory, resulting in low space utilization efficiency. Summary of the Invention

[0003] Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a vertical high-efficiency scallion cleaning device. By adopting vertical dynamic positioning cleaning, and utilizing a vertically arranged cam conveyor and fixed-point cleaning method, it solves the problems of cleaning dead zones, incomplete cleaning, and high material damage rate that exist in traditional horizontal conveying cleaning.

The cam with a step on the rotating shaft is used to adjust the position of the scallions in the tank by rotation, so that the scallions can be washed by the water flow from multiple directions. A mechanical brushing mechanism is set in a water tank and driven by a transmission shaft. The mechanism uses a roller brush set on the transmission shaft to brush the scallions on the cam step, so that the bristles of the roller brush turn the scallions and brush away the dirt on their surface. The turbulence mechanism uses double-bar driven turbulence blades. The two drive shafts drive the turbulence blades to stir the water flow and form a vortex, which further enhances the flushing force and carries away the mud and sand under washing, thereby improving the cleaning effect. A drive mechanism is mounted on the base and connected to a rotating shaft, a transmission shaft, and a drive shaft, thereby simultaneously providing driving force to the cam conveying mechanism, the mechanical brushing mechanism, and the turbulence mechanism. A discharge port is provided on one side of the water tank, an overflow pipe is installed on one side of the water tank, and a drain valve is installed at the bottom of the water tank.

A gear shaft is rotatably connected inside the gear frame via ball bearings. The gear shaft is provided with two gear parts of different diameters. The larger diameter gear part meshes with the first gear, and the smaller diameter gear part meshes with the second gear. The second gear is coaxially fixedly connected to the shaft wall of the rotating shaft. A drive motor is fixedly connected to the base, and a first sprocket is fixedly connected to the output end of the drive motor. A chain is wound around the first sprocket, and a second sprocket is wound inside the chain. The second sprocket is fixedly connected to one end of the drive shaft.

[0012] As a further description of the above technical solution, an air pump is installed on the base, and a diversion conduit with a one-way air outlet valve is installed at the exhaust end of the air pump. Multiple exhaust pipes are installed on the wall of the diversion conduit. One end of the exhaust pipe passes through the bottom of the water tank and is equipped with an aeration head. A large number of fine bubbles generated by the aeration heads arranged in the water tank gently impact and clean the scallions, removing mud and sand from the crevices.

The bubbles are responsible for impact without dead angles, and the turbine is responsible for generating high-intensity water flow. The two work together to achieve the cleaning effect of a large water tank in a small water tank. Attached Figure Description

Detailed Implementation

[0020] 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, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of the present invention.

[0021] Example 1 See attached document Figures 1-13 A vertical, high-efficiency scallion cleaning device includes a water tank 1, a base 2 fixed to the lower end of the water tank 1, an air flotation mechanism, and a water circulation system. It also includes: The cam conveying mechanism has two sets and is driven by the rotating shaft 15. This allows scallions to be put into the tank 1 at intervals from the top opening of the tank 1. The cam 14 with a step installed on the rotating shaft 15 is used to adjust the position of the scallions in the tank 1 by rotation, so that the scallions can be washed by the water flow from multiple directions. The cam conveying mechanism includes a U-shaped base plate 19 with holes. The U-shaped base plate 19 is fixed in the water tank 1. The rotating shaft 15 is fixed at equal intervals to the shaft wall of the rotating shaft 15. The rotating shaft 15 is rotatably connected in the water tank 1 through a sealed bearing. A synchronous belt 21 is provided on one side of the water tank 1. Two synchronous pulleys 22 are wound around the synchronous belt 21. The synchronous pulleys 22 are coaxially fixedly connected to one end of the rotating shaft 15. The two sets of cam conveying mechanisms are arranged in an upper and lower position and are not on the same vertical plane.

[0022] Two steps are provided and symmetrically distributed on the edge of the cam 14. The two outward spiral lines that make up the steps are each rotated 180 degrees and intersected by a straight line connecting the start and end points. Chamfers are provided at the intersection of the straight line and the end point. like Figure 14 As shown, the scallions, after being peeled, rooted, and having yellow leaves removed, are first fed into the device through the top inlet at intervals of approximately 6 seconds per scallion. A rotating brush 20 and a spray head 37 are located at the inlet of the water tank 1. After falling, the scallions are positioned above the cam 14. During this process, the brush bristles agitate the scallions, scrubbing away stubborn dirt. The cam's variable diameter adjusts the scallion's position (height, orientation), allowing it to be rinsed from multiple directions by the water flow. After this initial wash, the scallions are received by a specially shaped cam 14 located below. As it rotates, its radius gradually decreases, smoothly lowering the scallions. After rotating a certain angle, the cam is forcibly lifted off the device by a step and enters the water tank below. The specially shaped cam 14 then enables the smooth receiving, controlled descent, underwater transport, and precise lifting of the scallions from the water. This mechanism replaces complex conveyor belts and lifting devices, ensuring precise and reliable operation.

[0023] To improve cleaning efficiency, this technical solution also includes a mechanical brushing mechanism, comprising a first belt 12 with two first pulleys 23 wound around it. Two drive shafts 43 are rotatably connected to the water tank 1 via sealed bearings. One end of the first pulley 23 is fixedly connected to the drive shaft 43. One of the roller brushes 20 is located on one side of the discharge port. The mechanical brushing mechanism is set in the water tank 1 and driven by the drive shaft 43. The roller brush 20 on the drive shaft 43 is used to brush the scallions on the step of the cam 14, so that the bristles of the roller brush 20 turn the scallions and brush away the dirt on their surface. During this process, the stepping of the bristles of the roller brush 20 can brush away the stains and turn the scallions, improving the uniformity of cleaning.

[0024] During cleaning, this technical solution employs a double-rod driven turbulence blade 17 through a designed turbulence mechanism. Two drive shafts 16 drive the turbulence blade 17 to agitate the water flow and form a vortex, further enhancing the flushing force and carrying away the silt and sand, thus improving the cleaning effect. Specifically, the solution includes two fixed plates 18 supporting the drive shaft. Both fixed plates 18 are fixed inside the water tank 1 and rotatably connected to the drive shaft 16 through sealed bearings. A second belt 34 is provided on one side of the water tank 1, with two second pulleys 35 wound around it. The second pulleys 35 are coaxially fixedly connected to the drive shaft 16. Multiple turbulence blades 17 are provided and fixed at equal intervals on the shaft wall of the drive shaft 16. A third belt 11 is provided on one side of the water tank 1, with a third pulley 24 and a linkage pulley 25 wound around it. The third pulley 24 is fixedly connected to the shaft wall of the drive shaft 16, and the linkage pulley 25 is coaxially fixedly connected to the shaft wall of the transmission shaft 43. Finally, the cam 14 rotates, and the scallion is caught by the step on it and lifted out of the water, leaving the pool. It is then discharged by the roller brush 20 and the discharge guide plate 13. At the final outlet, a set of nozzles 36 directly connected to tap water sprays the scallion with a final rinse, using clean water to ensure the hygiene standards of the scallion. This completes the entire cleaning process.

[0025] This technical solution uses a single power source to simultaneously drive the cam conveying mechanism, the mechanical brushing mechanism, and the turbulence mechanism. It includes a gear frame supporting the transmission components, fixed to one side of the water tank 1. A half-shaft is rotatably connected within the gear frame via ball bearings. A first gear 30 and a fourth pulley 28 are fixedly connected to the shaft wall of the half-shaft. A fourth belt 27 is wound around the fourth pulley 28, and a fifth pulley 26 is wound within the fourth belt 27. The fifth pulley 26 is fixedly connected to the shaft wall of the drive shaft 16. A gear shaft 29 is rotatably connected within the gear frame via ball bearings. The gear shaft 29 has two gear sections with different diameters. The larger diameter gear section meshes with the first gear 30, and the smaller diameter gear section meshes with the second gear 10. The second gear 10 is coaxially fixedly connected to the shaft wall of the rotating shaft 15. A drive motor 7 is fixedly connected to the base 2. A first sprocket 8 is fixedly connected to the output end of the drive motor 7. A chain 9 is wound around the first sprocket 8. A second sprocket 6 is wound inside the chain 9. The second sprocket 6 is fixedly connected to one end of the drive shaft 16. The drive mechanism is set on the base 2 and connected to the rotating shaft 15, the transmission shaft 43 and the drive shaft 16. like Figure 2 , Figure 4 , Figure 5 , Figure 9 and Figure 10As shown, the drive motor 7 drives the directly connected first sprocket 8, which causes the chain 9 to drive the second sprocket 6 to rotate. The rotation of the second sprocket 6 drives the drive shaft 16 to drive the fifth pulley 26 and the third pulley 24 to rotate. When the third pulley 24 rotates, it drives the linkage pulley 25 to rotate through the third belt 11. When the linkage pulley 25 rotates, it drives the transmission shaft 43 to rotate. The linkage rotation of the two transmission shafts 43 is achieved through the first belt 12 and the first pulley 23, so that the two roller brushes 20 rotate synchronously. Furthermore, when the fifth pulley 26 rotates, it drives the fourth belt 27 to rotate the fourth pulley 28. The rotation of the fourth pulley 28 drives the half shaft to rotate the first gear 30. The rotation of the first gear 30 drives the large-diameter gear part of the gear shaft 29. At the same time, the small-diameter gear part drives the second gear 10 to rotate the rotating shaft 15. The rotating shaft 15, which is equipped with two sets of cam conveying mechanisms, can be linked by the synchronous belt 21 and the synchronous pulley 22 to complete the conveying operation when cleaning scallions.

[0026] A discharge port is provided on one side of the water tank 1, and an overflow pipe 33 is installed on the other side of the water tank 1 at the water level line height on the side wall. The overflow port is equipped with a filter screen. When the water level is too high, the sewage containing light impurities such as floating leaf fragments in the upper layer will overflow from here and enter the water storage area (i.e., the circulating water tank 32) to avoid the accumulation of impurities and ensure the balance of water circulation. A drain valve 39 is installed at the bottom of the water tank 1. The drain valve 39 is used for daily cleaning of the inside of the water tank 1 and to discharge the sediment inside. An air pump 3 is installed on the base 2. The exhaust end of the air pump 3 is equipped with a diversion pipe with a one-way air valve. Multiple exhaust pipes 38 are installed on the pipe wall of the diversion pipe. One end of the exhaust pipe 38 passes through the bottom of the water tank 1 and is equipped with an aeration head 40. A large number of fine bubbles are generated by the aeration heads 40 arranged in the water tank 1. The bubbles burst during the rising process and generate an impact force to gently clean the green onions and remove the sediment from the crevices.

[0027] A first water pump 4 and a circulating water tank 32 are installed on the upper end of the base 2. The inlet of the first water pump 4 is fixedly connected to the side wall of the circulating water tank 32 through a water intake pipe 31. The outlet of the first water pump 4 is fixedly connected to a return pipe 5, and multiple spray nozzles 37 are installed on the return pipe 5. After sedimentation and filtration, the first water pump 4 draws out the relatively clear water from the upper layer for preliminary brushing and spraying of the top. In addition, to improve the final cleaning effect, a second water pump 42 is fixedly connected to the base 2. A cleaning pipe 41 is installed on the outlet of the second water pump 42. The cleaning pipe 41 extends into the water tank 1 and is fixedly connected to multiple spray nozzles 36. The spray nozzles 36 face the discharge port, and a discharge guide plate 13 is inclinedly set at the discharge port.

[0028] According to the above technical solution, standardized scallions, after being peeled, rooted, and having yellow leaves removed, are intermittently fed into the inlet at the top of the device. They are initially cleaned with circulating water sprayed from nozzles. After falling, the scallions remain above cam 14, where they are turned and brushed by bristles to remove stubborn dirt. The scallions are then turned over, and their position is adjusted by the changing diameter of cam 14, allowing the surface to be rinsed by water from multiple directions. As cam 14 rotates, the scallions are supported by a specially shaped step, whose radius gradually decreases with rotation, thus smoothly lowering the height of the scallions. After rotating a certain angle, the step of cam 14 forces the scallions out of the brushing area and into the water below. A perforated U-shaped plate divides the water tank 1 into upper and lower layers. Driven by the cam, the scallions glide along the U-shaped plate over the water tank 1. Simultaneously, aeration heads 40 arranged in the lower layer of the U-shaped plate generate a large number of fine bubbles, providing a gentle impact clean to the scallions and removing mud and sand from the crevices. Furthermore, a double-rod driven turbulence blade 17 is installed in the water tank 1 to agitate the water flow and form a vortex, further enhancing the flushing force and improving the cleaning effect. The cam 14 continues to rotate, and the scallions are caught by the step on it and lifted out of the water, leaving the pool. With the help of the roller brush 20 and the discharge guide plate 13, the scallions are discharged. At the final outlet, a set of nozzles 36 directly connected to tap water sprays the scallions for a final rinse, using absolutely clean water to ensure the hygiene standards of the scallions.

[0029] When using this invention, the working principle or process is as follows.

[0030] (1) Feeding and initial washing section: First, the scallions, after being peeled, rooted, and having yellow leaves removed, are fed into the device from the top at intervals of approximately 6 seconds per scallion. They undergo initial rinsing by a rotating roller brush 20 and spray nozzles 37. After falling, the scallions remain above cam 14, where the brush bristles agitate and scrub away stubborn dirt. The cam 14's variable diameter adjusts the scallion's position, ensuring it is rinsed from multiple angles.

[0031] (2) Conveying and Immersion Cleaning Section: After initial washing, the scallions are supported by a specially shaped cam 14. As it rotates, its radius gradually decreases, thus smoothly lowering the height of the scallions. After rotating a certain angle, the scallions are forcibly carried away from the device by the steps and into the water pool below.

[0032] (3) Bubble-assisted cleaning: The aeration heads 40 arranged in the lower layer of the pool generate a large number of fine bubbles, which gently impact and clean the scallions, removing mud and sand from the crevices.

[0033] (4) Vortex cleaning: During the aeration process, the water flow can be stirred by the double-rod driven turbulence blades 17 installed in the water tank 1 to form a vortex, which can further enhance the flushing force and improve the cleaning effect.

[0034] (5) Effluent and final wash section: Finally, the cam 14 rotates, causing the scallion to be caught by the step above it and lifted out of the water, detaching it from the pool. The scallion is then discharged using the roller brush 20 and the discharge guide plate 13. At the final outlet, a set of spray nozzles 36 directly connected to tap water sprays the scallion with a final rinse, using clean water to ensure the scallion meets hygiene standards, thus completing the entire cleaning process.

[0035] When using this equipment, the essential water circulation system must perform the following functions: Staged filtration: The wastewater after cleaning falls through the holes in the perforated U-shaped plate 19. The bottom of the water tank 1 is equipped with an outlet with a filter cover, which will intercept most of the mud and sediment.

[0036] Sedimentation and circulation: Water flows into the lowest circulating water tank 32, where the flow rate slows down and finer particles settle. The inlet of the first water pump 4 is raised to draw out the relatively clear water from the upper layer for the top scrubbing spray.

[0037] Water level and scum control: An overflow pipe 33 with a filter screen is installed at the water level line on the side wall of the water tank. When the water level is too high, the wastewater containing light impurities such as floating leaf fragments in the upper layer will overflow from this pipe and enter the circulating water tank below, ensuring the balance of water circulation.

[0038] This technical solution can filter floating matter and sediment. The cleaning water is filtered once and then enters the sedimentation tank (circulating water tank 32) to settle fine sand and gravel. The water is pumped out from a distance and recycled, which greatly reduces water consumption and has a high water utilization rate. It conforms to the concept of green production. Clean water is only used in the final spraying stage to ensure a clean cleaning effect.

[0039] Secondly, the traditional long strip cleaning tank is transformed into a three-dimensional structure of "vertical direction + small area water pool", which greatly saves ground space, makes it easy to integrate into automated production lines, has high space utilization, and occupies a small area.

[0040] In addition, the upper part of the water tank 1 combines brushing and spraying, the cam controls the relative height, and the brush roller enables the green onions to be tumbled and cleaned at fixed points, with no dead corners in the cleaning process.

[0041] The lower part allows the strong turbulent water flow generated by the bubbles and turbine to be combined, achieving deep cleaning of scallions in a small pool, avoiding the problems of stagnant water flow and uneven cleaning in some areas of traditional large pools.

[0042] The entire equipment requires only a row of nozzles and a small number of bubble nozzles, significantly reducing the power and pressure requirements of the water pump. It consumes less water, resulting in lower water and treatment costs over the long term. Moreover, the entire process, from input, brushing, rinsing, extraction to water output, is precisely controlled by a cam mechanism, ensuring smooth transitions. This makes it ideal for integration with front-end normalization equipment and back-end packaging equipment.

[0043] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
