Description

TECHNICAL FIELD

[0001] The present application relates to a ginseng fruit efficient and low-damage cleaning system and method, in particular to a ginseng fruit efficient and low-damage cleaning system and method suitable for 7-8 mature ginseng fruit with delicate skin, and belongs to the technical field of fruit cleaning. BACKGROUND

[0002] As a fruit with high economic value, ginseng fruit is usually harvested at the stage of 7 maturity or above. At this time, the fruit skin is extremely delicate and easily damaged during cleaning, handling and other processes, thereby affecting the appearance, taste and storage time of the fruit, causing economic losses to the farmers.

[0003] Among them, cleaning is a necessary link in ginseng fruit processing, which directly affects food safety and product quality. At present, in the main producing areas of ginseng fruit, farmers mainly rely on traditional manual cleaning method to clean ginseng fruit. This cleaning method has many obvious defects. First of all, the efficiency is extremely low and the cost is high. According to the actual production data statistics, 4 fruit washing workers can only clean about 100 baskets (about 3000 kg) of ginseng fruit a day, and the labor cost is as high as 600 yuan. During the peak period of ginseng fruit picking, due to the fact that the cleaning speed is far slower than the picking speed, a large number of ginseng fruits cannot be cleaned in time, which easily leads to over-ripening, rotting and deterioration of the fruits, causing huge economic losses. Secondly, the labor intensity is large and the working environment is poor. Workers need to immerse their hands in cold water for a long time to repeatedly scrub ginseng fruit, which not only causes serious harm to the hands of workers, but also may cause joint diseases and other health problems in the long run. At the same time, it also makes it difficult to recruit workers for this position, making it difficult to meet the needs of large-scale production.

[0004] In addition to the traditional manual cleaning method, there are also some general fruit cleaning machines on the market, such as cleaning machines for apples, pears and other fruits. However, these models are not suitable for ginseng fruit with more than 7 maturity. On the one hand, the rigid brushing system of these general fruit cleaning machines is easy to cause scratches, wear and other damage to the delicate skin of ginseng fruit during cleaning, affecting the quality of the fruit. On the other hand, the bubble cleaning unit of these machines usually adopts high-pressure water spraying or high-density bubble design, which easily leads to violent collision of ginseng fruit in the tank. In addition, the design of the discharging and basket loading link is not reasonable. The discharge outlet is usually designed to directly fall into the basket or to be concentrated and unloaded after being carried by a tray. The falling height of the fruit is generally more than 20 cm. The fruit will be severely mechanically damaged due to mutual collision and impact with the basket during the falling process, resulting in a significant decrease in fruit quality, which cannot meet the quality requirements of farmers for commodity fruit. Therefore, these existing machines cannot be widely applied in ginseng fruit cleaning operations. Although the Chinese utility model patents with application numbers 202020082270.2 and 202321093144.7 respectively disclose cleaning devices specially used for ginseng fruit, the effect is not ideal.

[0005] In summary, the development of a dedicated ginseng fruit cleaning machine and cleaning method that can balance high efficiency, low cost and extremely low damage rate, solving the pain points in the cleaning process of 7 mature ginseng fruit, has become a technical problem that needs to be solved in the current ginseng fruit industry development. SUMMARY

[0006] (I) Technical problems to be solved The technical problem to be solved by the present application is to solve the problem that the existing cleaning of 7 mature ginseng fruit cannot balance high efficiency, low cost and extremely low damage rate.

[0007] (II) Technical solutions In order to solve the above technical problems, on the one hand, the present application provides a high-efficiency, low-damage ginseng fruit cleaning system, which comprises a cleaning mechanism and a collecting mechanism, the collecting mechanism is arranged at the discharge end of the cleaning mechanism, the collecting mechanism comprises a buffer tank, the buffer tank is filled with a buffer solution, and the ginseng fruit cleaned by the cleaning mechanism falls into the buffer solution for collection. The buffer tank is a key device for solving the slow basket loading speed of washed ginseng fruit and reducing the collision damage between fruits. It can not only be applied to the present cleaning system, but also be applied to ginseng fruit grading machines, and can also be applied to the collection of other fruits and the like after cleaning processing, and has wide applicability.

[0008] Further, the cleaning mechanism comprises a bubble cleaning machine and a brush cleaning machine, the brush cleaning machine is arranged at the discharge end of the bubble cleaning machine, and the buffer tank is arranged at the discharge end of the brush cleaning machine; the bubble cleaning machine comprises a cleaning tank and a bubble generating device arranged at the bottom of the cleaning tank, and the brush cleaning machine comprises a rack, a plurality of brush rollers arranged on the rack, and a spraying device arranged above the brush rollers, the brush of the brush roller is a soft brush, and the brush density of the brush is 300-400 / cm 2 , for example, 300 / cm 2 , 320 / cm 2 , 340 / cm 2 , 360 / cm 2 , 380 / cm 2 , 400 / cm 2 , and the diameter of the bristles is 0.1-0.15mm, for example, 0.11mm, 0.12mm, 0.13mm, 0.14mm.

[0009] Further, a first buffer mechanism is arranged between the bubble cleaning machine and the brush cleaning machine, and a first discharge hopper is arranged at the discharge end of the bubble cleaning machine. The first buffer mechanism comprises a support and a first upper buffer pad. The support is arranged at the discharge end of the bubble cleaning machine, and a slide is arranged on the support. One end of the first upper buffer pad is slidably connected with the slide and is limited by a bolt (the height of the first upper buffer pad can be changed by adjusting the bolt, so that the relative position relationship between the first upper buffer pad and the first discharge hopper is changed, so as to better buffer and protect the ginseng fruits), and the other end of the first upper buffer pad abuts against the first discharge hopper. A supporting rod for supporting the first upper buffer pad is arranged on the first discharge hopper. Further, a second buffer mechanism is arranged between the brush cleaning machine and the buffer pool, and a second discharge hopper is arranged at the discharge end of the brush cleaning machine. The second buffer mechanism comprises a second upper buffer pad and a hanging soft pad. The second upper buffer pad is arranged on the brush cleaning machine above the second discharge hopper, and the hanging soft pad is arranged at the lower end of the second discharge hopper, so as to buffer and protect the ginseng fruits sent out by the brush cleaning machine.

[0010] Further, the second buffer mechanism further comprises a floating soft pad. The floating soft pad is arranged at the lower end of the hanging soft pad and floats on the buffer liquid in the buffer pool. The gap between the end of the second upper buffer pad close to the floating soft pad and the floating soft pad is not greater than 5 mm. The buffering and protecting effect of the ginseng fruits sent out by the brush cleaning machine is further improved.

[0011] Further, the second upper buffer pad and the floating soft pad jointly constitute a smooth buffer slide. The inclination angle of the buffer slide is 15-20°, for example, 16°, 17°, 18°, 19°, etc. The inclination angle of the buffer slide ensures that the sliding speed of the fruits is controlled to be 0.2-0.3 m / s.

[0012] Further, an inclined guide plate with an inclination angle of 30-45° is arranged at the end of the bubble cleaning machine away from the brush cleaning machine. The guide plate is arranged at the feeding end of the cleaning tank body in an inclined manner, and is used for guiding the ginseng fruits to stably enter the cleaning tank. Soft pads are arranged on the guide plate, the first discharge hopper and the second discharge hopper respectively, so as to protect the ginseng fruits rolling down from above and also have a certain buffering effect.

[0013] Further, the bubble cleaning machine and the brush cleaning machine are provided with a conveying belt assembly, the conveying belt assembly comprises a baffle conveying belt and a baffle edge arranged on both sides of the baffle conveying belt, a plurality of transverse partitions are arranged on the baffle conveying belt, the distance between the two transverse partitions is 15-30 cm, the height of the transverse partition is 2-5 cm, and the two ends of the transverse partition are respectively provided with an upwardly curved baffle, the curved baffle is arranged at a distance of 6-10 cm from the baffle edge; the discharge end of the bubble cleaning machine is provided with a guide plate on both sides of the baffle conveying belt. With the rotation of the baffle conveying belt, the ginseng fruits flowing with the water flow are taken out through the transverse partitions, in the process, the ginseng fruits on both sides of the lower end of the baffle conveying belt are guided to the transverse partitions through the guide plates, and the ginseng fruits on the transverse partitions are prevented from falling off from the two ends of the transverse partitions by the curved baffles during the climbing of the baffle conveying belt, the curved baffles are arranged at a distance from the baffle edge, and the ginseng fruits are not in contact with the baffle edge of the conveying belt assembly during the conveying process, thereby reducing the fruit damage.

[0014] Further, the normal liquid level in the buffer pool is 4 / 5 of the height of the pool wall, which can ensure the buoyancy buffering effect of the water body on the fruits and avoid the overflow of the fruits floating. The buffer pool is provided with a collecting net bag. The collecting net bag is used to prevent some ginseng fruits with large density from directly falling on the pool bottom to cause damage and to facilitate the quick collection of the washed ginseng fruits, thereby improving the basket loading efficiency. The collecting net bag adopts a soft net, and the mesh size can prevent the ginseng fruits from falling down and avoid the accumulation of impurities.

[0015] On the other hand, the present application also provides a high-efficiency and low-damage cleaning method for ginseng fruits, which adopts the above-mentioned high-efficiency and low-damage cleaning system for ginseng fruits, and comprises the following steps: Step one, the harvested ginseng fruits are slowly poured into the cleaning tank of the bubble cleaning machine through the guide plate, the bubble generating device of the bubble cleaning machine generates 500-800 low-density bubbles per cm 3 •min, for example, 600 per cm 3 •min, 700 per cm 3 •min, the ginseng fruits are preliminarily cleaned by the bubbles, the cleaning time is controlled to be 1-2 minutes, the preliminary cleaning effect is ensured, and the damage caused by excessive rolling of the ginseng fruits in the tank is avoided, and most of the soil and fallen leaves are washed away; Step Two: After initial cleaning by the bubble washing machine, the ginseng fruit is conveyed out of the bubble washing machine's outlet via a conveyor belt assembly, driven by the water flow. After being buffered and decelerated by the first buffer mechanism, it smoothly enters the brush washing machine. The brush roller speed is adjusted according to the ginseng fruit's maturity and surface clay adhesion (which can be achieved through visual inspection equipment; existing technology is sufficient and will not be elaborated upon here). For example, 180-220 r / min is used when the fruit is 70% mature, and 220-280 r / min is used when it is 80% mature (for example, 180-220 r / min can be used when the surface clay content of 70% ginseng fruit is around 10%, and 220-280 r / min when the surface clay content is around 20-30%). Fine, soft brushes are then used to scrub the red clay off the ginseng fruit. Step 3: The ginseng fruit, cleaned by the brush cleaning machine, is sent to the discharge port of the brush cleaning machine under the rotation of the brush. The fruit first contacts the suspension pad of the second buffer mechanism to achieve initial deceleration, and then slowly slides into the buffer pool along the buffer slide formed by the second upper buffer pad and the floating pad. The inclination angle of the buffer slide ensures that the fruit's sliding speed is controlled at 0.2-0.3m / s. Step 4: The ginseng fruits entering the buffer pool float on the surface because the density of water is greater than their own. The viscosity of the water further absorbs the impact energy of the fruits, preventing violent squeezing between them. Afterward, workers only need to use fruit baskets with drainage holes on the bottom and sides to gently scoop up the floating ginseng fruits in the buffer pool to complete the basketing. During the basketing process, the fruits are always protected by water. After the baskets are filled, they are lifted out to drain the water on the surface of the fruits for 20-50 seconds (e.g., 30 seconds, 40 seconds, etc.) to complete the washing.

[0016] (III) Beneficial Effects The above-described technical solution of the present invention has the following advantages: This invention, through the establishment of an automated cleaning mechanism and a buffer pool at the discharge end of the cleaning mechanism for fruit drop, buffering, and cleaning, and equipped with multiple buffering mechanisms, achieves a soft landing of the fruit from discharge to crating, significantly improving cleaning efficiency, significantly reducing labor costs, reducing costs and fruit damage rates, optimizing the crating process, and promoting the upgrading of the ginseng fruit industry, possessing extremely high economic and practical value. This invention can greatly reduce the damage rate of ginseng fruit that is 70% ripe or more during the cleaning, discharge, and crating process, forming a dedicated cleaning system and corresponding cleaning method.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0025] Example 1 like Figure 1 , Figure 2As shown, a high-efficiency, low-damage ginseng fruit cleaning system includes a cleaning mechanism and a collection mechanism. The collection mechanism is located at the discharge end of the cleaning mechanism and includes a buffer tank 1 filled with a buffer solution. The ginseng fruits, after being cleaned by the cleaning mechanism, fall into the buffer solution for collection. The buffer solution in the buffer tank 1 is typically made of clean water. The fruits ultimately fall into the water in the buffer tank 1. Due to the density of water (1 g / cm³), the water... 3 The density is greater than that of ginseng fruit (0.8-0.9 g / cm³). 3 The fruit will float in the water; the viscosity of the water can further absorb the remaining impact energy of the fruit during its fall, while the buoyancy of the water supports the fruit and prevents the fruit from being squeezed violently by gravity, thereby minimizing fruit damage.

[0026] More specifically, the cleaning mechanism includes a bubble cleaner 2 and a brush cleaner 3. The brush cleaner 3 is located at the discharge end of the bubble cleaner 2, and the buffer tank 1 is located at the discharge end of the brush cleaner 3. The bubble cleaner 2 includes a cleaning tank 4 and a bubble generating device 5 (existing technology is acceptable) located at the bottom of the cleaning tank 4. The brush cleaner 3 includes a frame 6, multiple brush rollers 7 mounted on the frame 6, and a spraying device 8 located above the brush rollers 7. It is understood that the brush cleaner 3 typically also includes a power system to drive the brush rollers 7 to rotate, such as a combination of a servo motor and a transmission belt, and the servo motor speed is adjustable (variable frequency motor), thereby making the speed of the brush rollers 7 adjustable and flexibly adaptable according to the fruit ripeness and clay adhesion. The brushes of the brush rollers 7 are fine and soft brushes, and the bristle density of the brushes is 300-400 bristles / cm. 2 The bristle diameter is 0.1-0.15mm. Generally, the soft bristles on the brush roller 7 are arranged evenly in a cylindrical shape. However, in order to improve the brushing effect on ginseng fruit, the soft bristles on the brush roller 7 can also be arranged in an uneven structure or a spiral arrangement.

[0027] More specifically, the cleaning tank 4 of the bubble washing machine 2 is made of food-grade stainless steel, with a width of 80-200cm, a length of 300-450cm, and a depth of 60-80cm, ensuring sufficient cleaning space for the ginseng fruit without excessive accumulation; the bubble generating device 5 is installed at the bottom of the cleaning tank 4, employing a microporous aeration disc design, with a bubble generation density controlled at 500-800 bubbles / cm³. 3 •min, which can remove surface impurities through bubble turbulence while avoiding violent collisions of the fruit caused by high-density bubbles. Addressing the problem of difficult-to-remove red clay adhering to the surface of ginseng fruit in Yunnan and other regions, the brush cleaning machine 3 uses finer, soft brushes made of nylon with a bristle density of 300-400 bristles / cm². 2The brush bristles are 0.1-0.15mm in diameter. This brush design ensures that the red clay on the surface of the ginseng fruit can be effectively washed away while minimizing damage to the delicate skin of the ginseng fruit, thus achieving a balance between cleanliness and low damage rate.

[0028] Example 2 The only difference between this embodiment and Embodiment 1 is that it also includes a multi-stage buffer and deceleration system. This system is the core of achieving low-damage transportation of ginseng fruit and is set at two key locations to buffer and decelerate the ginseng fruit. Specifically, a first buffer mechanism is set between the bubble washing machine 2 and the brush washing machine 3. The discharge end of the bubble washing machine 2 is provided with a first discharge hopper 9. The first buffer mechanism includes a bracket 10 (made of aluminum alloy and fixed by fixing screws) and a first upper buffer pad 11. The bracket 10 is set at the discharge end of the bubble washing machine 2 and is provided with a slide rail 12. One end of the first upper buffer pad 11 is slidably connected to the slide rail 12 and limited by a bolt 13 (by adjusting the bolt 13, the height of the first upper buffer pad 11 can be flexibly changed, with an adjustment range of 5-20cm, so as to find the most suitable buffer position), and the other end abuts against the first discharge hopper 9. The first discharge hopper 9 is provided with a support rod 14 for supporting the first upper buffer pad 11. The aforementioned bracket 10 can be, for example, a rectangular frame structure, with grooves opened on the vertical bars on both sides of the rectangular frame, and then a crossbar is set in the groove. The crossbar is fastened to the rectangular frame with bolts 13 (or nuts) to facilitate height adjustment. The first upper buffer pad 11 is then fixed to the crossbar.

[0029] The system also includes a second buffer mechanism between the brush washing machine 3 and the buffer tank 1. The brush washing machine 3 has a second discharge hopper 15 at its discharge end. The second buffer mechanism includes a second upper buffer pad 16 and a suspended soft pad 17. The second upper buffer pad 16 is positioned on the brush washing machine 3 above the second discharge hopper 15, and the suspended soft pad 17 is positioned below the second discharge hopper 15. The second buffer mechanism also includes a floating soft pad 18, which is positioned below the suspended soft pad 17 and floats on the buffer solution in the buffer tank 1. The gap between the end of the second upper buffer pad 16 near the floating soft pad 18 and the floating soft pad 18 is no greater than 5mm (or they can be in direct contact). The second upper buffer pad 16 and the floating soft pad 18 together form a smooth buffer slide (which can be understood as the ginseng fruit rolling out along the floating soft pad 18 via the second upper buffer pad 16), with an inclination angle of 15-20°.

[0030] The first upper buffer pad 11 is made of a sponge and waterproof cloth composite material, with a thickness of 3-5cm and moderate softness. This device is mainly used to buffer the impact force generated by the height difference (usually 15-25cm) at the connection between the bubble washing machine 2 and the brush washing machine 3, preventing the ginseng fruit from being damaged due to falling during the process of entering the brush washing machine 3 from the bubble washing machine 2. The hanging soft pad 17 is made of silicone material, with a thickness of 3-5cm, and is used to conform to the shape of the ginseng fruit. When the ginseng fruit is sent out from the discharge port of the brush washing machine 3, it first contacts the hanging soft pad 17 to achieve initial deceleration and reduce the movement speed and kinetic energy of the fruit. The second upper buffer pad 16 is made of the same sponge and waterproof cloth composite material as the first upper buffer pad 11, with a length of 60-200cm and a width of 10-40cm; the floating soft pad 18 is made of closed-cell foam and waterproof cloth composite material with a density of 0.3-0.4g / cm³. 3 It ensures that it can float naturally on the water surface, and its size is compatible with the second upper cushioning pad 16.

[0031] Example 3 This embodiment is a further optimization and refinement of the cleaning mechanism based on Embodiment 2. In this embodiment, the end of the bubble cleaner 2 away from the brush cleaner 3 is provided with a guide plate 19 (made of food-grade silicone material, with a smooth and burr-free surface) with an inclination angle of 30-45°. Soft pads 20, such as rubber or sponge, are respectively provided on the guide plate 19, the first discharge hopper 9, and the second discharge hopper 15. A conveyor belt assembly is provided between the bubble cleaner 2 and the brush cleaner 3. The conveyor belt assembly includes a baffle conveyor belt 21 and side rails 22 provided on both sides of the baffle conveyor belt 21 (generally also including a motor to drive the conveyor belt to rotate, etc., not shown in the attached drawings; existing technology can be used). Figure 4 As shown, the baffle conveyor belt 21 is provided with multiple transverse partitions 23. The distance between each pair of transverse partitions 23 is 15-30cm, the height of the transverse partitions is 2-5cm, and each end of the transverse partition 23 is provided with an upward-curving wedge 24. The wedge 24 is set at a distance of 6-10cm from the side guard 22. The discharge end of the bubble washing machine 2 is located on both sides of the baffle conveyor belt 21 and is also provided with guide plates 25.

[0032] Example 4 This embodiment is a further optimization and refinement of the collection mechanism based on Embodiment 3. In this embodiment, the wall height of the buffer pool 1 is 60-90cm, and the normal water level in the buffer pool 1 is 4 / 5 of the wall height. Figure 3 As shown, a collection net 26 (square net) is installed in the buffer pool 1.

[0033] Example 5 This embodiment provides a method for cleaning ginseng fruit using the high-efficiency, low-damage ginseng fruit cleaning system described in the above embodiment, including the following steps: Step 1: Slowly pour the harvested ginseng fruits (approximately 30 kg per basket) into the washing tank 4 of the bubble washing machine 2 through the guide plate 19, avoiding direct impact of the fruits against the tank wall. The bubble generating device 5 of the bubble washing machine 2 produces 500-800 bubbles / cm³. 3 • Low-density bubbles (min) are used to initially clean the ginseng fruit through bubble turbulence, with the cleaning time controlled at 1-2 minutes; this completes the pre-cleaning process; during this stage, low-density bubbles are used to prevent the fruit from violently colliding within the tank.

[0034] Step Two: After initial cleaning by the bubble washing machine 2, the ginseng fruit is conveyed out of the outlet of the bubble washing machine 2 by the water flow through the conveyor belt assembly. After being buffered and decelerated by the first buffer mechanism, it smoothly enters the brush washing machine 3. The speed of the brush roller 7 is adjusted according to the ripeness of the ginseng fruit and the amount of clay adhering to the surface. When the fruit is 70% ripe, 180-220 r / min is selected, and when it is 80% ripe, 220-280 r / min is selected. The fine soft brush is used to thoroughly scrub away the residual red clay (for ginseng fruit from Yunnan) on the ginseng fruit to ensure that the ginseng fruit is clean. In this stage, the cleaning effect and the need for low damage are balanced by adapting the speed and soft brush. Step 3: The ginseng fruit cleaned by the brush cleaning machine 3 is sent to the discharge port of the brush cleaning machine 3 under the action of the rotating brush. The fruit first comes into contact with the suspension soft pad 17 of the second buffer mechanism to achieve initial deceleration. Then, it slowly slides into the buffer pool 1 along the buffer slide formed by the second upper buffer pad 16 and the floating soft pad 18. The inclination angle of the buffer slide ensures that the fruit's sliding speed is controlled at 0.2-0.3m / s, avoiding the direct impact of the fruit falling. Step 4: The ginseng fruits entering buffer pool 1 float on the surface of the water because the density of the water is greater than their own density. The viscosity of the water further absorbs the impact energy of the fruits, effectively preventing violent squeezing between the fruits. Afterwards, the workers only need to use fruit baskets with drainage holes on the bottom and sides to gently scoop up the floating ginseng fruits in buffer pool 1 to complete the basketing. During the basketing process, the fruits are always protected by water. After the baskets are filled, they are lifted out to drain the water on the surface of the fruits. The draining time is about 20-50 seconds, and the entire cleaning process is complete.

[0035] Under traditional manual cleaning methods, four workers can only clean 100 baskets of ginseng fruit per day, with labor costs reaching approximately 600 yuan and a cleaning efficiency of 100 baskets / day. However, using the complete cleaning system of this invention, 100 baskets of ginseng fruit can be cleaned in just one hour, with energy consumption (approximately 5-8 kWh / hour) and labor costs (only one worker is needed to monitor the equipment and load the baskets) of only about 300 yuan. Therefore, the cleaning efficiency of this invention is 24 times higher than traditional manual cleaning, saving fruit farmers 300 yuan per cleaning operation, significantly reducing production costs, improving production efficiency, and preserving the appearance of the cleaned ginseng fruit.

[0036] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

9. The ginseng fruit high-efficiency, low-damage cleaning system according to claim 1, characterized in that: The normal liquid level in the buffer tank is 4 / 5 of the height of the tank wall, and a collecting net bag is arranged in the buffer tank.

10. A ginseng fruit high-efficiency, low-damage cleaning method, characterized in that, The ginseng fruit high-efficiency and low-damage cleaning system of claim 8 comprises the following steps: Step one, the collected ginseng fruit is slowly poured into the cleaning tank of the bubble cleaning machine through the guide plate, the bubble generating device of the bubble cleaning machine generates 500-800 low-density bubbles per cm 3 min, the ginseng fruit is preliminarily cleaned by the bubble stirring, and the cleaning time is controlled for 1-2 minutes. Step two: after the ginseng fruits are preliminarily cleaned by the bubble cleaning machine, the ginseng fruits are sent out from the discharge port of the bubble cleaning machine by the conveying belt assembly under the action of water flow, then enter the brush cleaning machine stably after buffering and speed reduction by the first buffering mechanism, and the rotating speed of the brush roller is adjusted according to the maturity and surface clay adhesion of the ginseng fruits, 180-220 r / min is selected when the ginseng fruits are 70% mature, and 220-280 r / min is selected when the ginseng fruits are 80% mature. Step three: the ginseng fruit cleaned by the brush washing machine is sent to the discharge port of the brush washing machine under the rotation of the brush, first contacts the suspended soft pad of the second buffer mechanism to realize preliminary speed reduction, and then slowly slides into the buffer pool along the buffer slide formed by the second upper buffer pad and the floating soft pad. The inclination angle of the buffer slide ensures that the sliding speed of the fruit is controlled at 0.2-0.3 m / s; Step four: the ginseng fruit entering the buffer pool floats on the water surface because the density of water is greater than the density of itself, and the viscous force of the water body further absorbs the impact energy of the fruit; then, the worker only needs to gently pick up the floating ginseng fruit in the buffer pool with a fruit basket provided with water-permeable holes at the bottom and the side to complete the basket loading. The fruit is always in the water protection state during the basket loading process, the fruit basket is lifted out after the basket loading is completed, the water on the surface of the fruit is drained, the draining time is 20-50 seconds, and the cleaning is completed.
