Description

Technical Field

[0001] This invention relates to the field of processing technology of *Trifolium repens*, specifically to a *Trifolium repens* cleaning device. Background Technology

[0002] *Trifolium repens* is a herbaceous vine belonging to the genus *Trifolium* in the family Vitaceae. Its branches are slender and smooth; leaves are lanceolate; inflorescences are axillary, covered with short, soft hairs, and the pedicels also have short, grayish hairs; petals are ovate; fruit is nearly spherical; seeds are obovate-elliptic, with depressions on both sides extending obliquely from the lower part to the top of the seed; flowering period is from April to June; fruiting period is from August to November.

[0003] Trifoliate haematomarginatus is native to China and grows mostly in shady places under mixed coniferous and broad-leaved forests or mixed woodlands on hillsides or along mountain gullies and streams. Trifoliate haematomarginatus has relatively high environmental requirements, preferring cool, moist climates; it is drought-tolerant but dislikes waterlogging; it is not particular about soil type, but thrives best in humus-rich and calcareous soils. The main method of propagation for Trifoliate haematomarginatus is through cuttings.

[0004] According to the Compendium of Materia Medica, *Trifolium repens* is slightly bitter and enters the liver and lung meridians. It has the effects of clearing heat and detoxifying, reducing swelling and relieving pain, and resolving phlegm and nodules. It is mainly used to treat infantile high fever and convulsions, whooping cough, sores and phlegm nodules, and snake bites. *Trifolium repens* can be harvested year-round and is often used in cooking. It also has unique therapeutic effects on various febrile diseases, edema, and snake bites. In addition, *Trifolium repens* has good anti-cancer properties and is known as a "plant antibiotic." After processing, it can be made into anti-cancer products, which have certain economic value.

[0005] Three-leaf green tea can also be made into tea. It needs to be picked by hand and then washed. Manual washing is inefficient, has high labor costs and low returns. In addition, different operators may not wash the three-leaf green leaves thoroughly, which affects the quality of the product.

[0006] There are cleaning machines on the market for cleaning plant roots and stems, but when cleaning Trifoliate Orange by stirring, its leaves are easily damaged and its internal components are easily lost. At the same time, the damaged leaves affect the quality and shape of the subsequent products. Therefore, we propose a Trifoliate Orange cleaning device. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the existing defects and provide a Trifoliate Gynostemma pentaphyllum cleaning device, which cleans Trifoliate Gynostemma pentaphyllum by vibration, reduces damage to the leaves of Trifoliate Gynostemma pentaphyllum, and ensures a certain processing efficiency, thus effectively solving the problems in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a three-leaf ginseng cleaning device, comprising a water tank, a cleaning cylinder, an opening and closing cover, and a negative pressure pump;

[0009] The inner cavity of the water tank is divided into a feeding chamber, a washing chamber and a recovery chamber by two partitions. The partitions have a circular mounting hole in the middle and a return hole on the lower side.

[0010] The cleaning cylinder is set inside the cleaning chamber, with the inlet and outlet ends at its two ends, respectively. Both ends are connected to the circular mounting holes in the middle of two partitions. Side suction grooves are distributed on the side wall of the cleaning cylinder.

[0011] The opening and closing cover is located on the outside of the cleaning cylinder, and the opening and closing side suction groove is rotated. The side wall of the opening and closing cover is provided with connecting grooves.

[0012] The water tank is filled with water, and the water completely covers the entire cleaning cylinder;

[0013] The negative pressure pump is fixed to the discharge end of the cleaning cylinder by a bracket. A flow divider is provided at the inlet of the negative pressure pump. The discharge end of the cleaning cylinder is contracted and covers the outside of the negative pressure pump. A flow gap is reserved between the negative pressure pump and the cleaning cylinder for water supply and blade passage.

[0014] The flow divider is hemispherical in shape, with a mesh in the center to isolate the blades. The concave surface of the flow divider faces the negative pressure pump. The hemispherical flow divider serves to guide the flow and reduce the impact on the jujubes during movement, greatly minimizing damage.

[0015] Furthermore, the *Trifolium repens* cleaning device also includes an inner isolation net, which is fixed to the inner wall of the cleaning cylinder and covers all the side suction grooves. The inner isolation net prevents *Trifolium repens* from passing through the side suction grooves during vibration;

[0016] The *Trifolium repens* cleaning device also includes a drain pipe. A collection trough communicating with the inner cavity of the water tank is located at the bottom, and the collection trough is connected to the drain pipe. The drain pipe is used to pump out the dirt deposited at the bottom of the water tank.

[0017] Furthermore, the inner wall of the opening and closing cover is provided with an annular groove, and a support bearing is installed in the annular groove. The inner ring of the support bearing is in contact with the outer wall of the cleaning cylinder, and a flexible sealing ring that is in contact with the outer wall of the cleaning cylinder is also fixed at the end of the opening and closing cover. The support bearing ensures that the opening and closing cover rotates smoothly on the cleaning cylinder, and the flexible sealing ring ensures the airtightness of the gap between the cleaning cylinder and the opening and closing cover when the side suction groove is in the closed state.

[0018] Furthermore, the side suction groove is a strip-shaped hole, which is evenly distributed along the axis of the cleaning cylinder and parallel to the axis of the cleaning cylinder. The side suction groove is periodically opened and closed by the opening and closing cover, and the water flow on the outside periodically enters the inner side of the cleaning cylinder radially through the side suction groove, colliding with the axial fluid inside the cleaning cylinder, causing the fluid to vibrate, thereby performing vibration cleaning of the Clematis armandii, which can ensure cleaning efficiency and quality.

[0019] Furthermore, the side suction groove is composed of linearly distributed circular holes, the cross-section of which is conical. When the fluid passes through the conical circular holes, diffusion and contraction occur, further creating turbulence in the water and improving the cleaning quality.

[0020] Furthermore, the connecting groove is strip-shaped, with its length direction forming an angle with the axis of the opening and closing cover, and adjacent connecting grooves do not coincide in the cross-sectional direction. When the connecting groove coincides with the side suction groove, the side suction groove opens, and water from the outside radially enters the cleaning cylinder.

[0021] Furthermore, the *Trifolium repens* cleaning device also includes a pump drive mechanism, which includes a motor, a belt, and a connecting shaft. The motor is mounted on the outer side of the water tank, and the connecting shaft is rotatably connected to the inner wall of the water tank. The connecting shaft is fixedly connected to the shaft of the negative pressure pump. Both the connecting shaft and the output shaft of the motor are equipped with pulleys, and the two pulleys are connected by belt drive.

[0022] Furthermore, the *Trifolium repens* cleaning device also includes a rotating drive mechanism for the opening and closing cover. This mechanism comprises a reduction gearbox, gears, and a gear ring. The reduction gearbox is fixed to the side wall of the water tank. The input shaft of the reduction gearbox is fixedly connected to the output shaft of the motor. A gear is fixed on the output shaft of the reduction gearbox, and a gear ring meshing with the gear is fixed on the opening and closing cover. The differential speed movement of the opening and closing cover and the negative pressure pump, driven by a single motor, facilitates control.

[0023] Furthermore, the *Trifolium repens* cleaning device also includes a recovery chamber lifting mechanism. This mechanism comprises an extension shell, positioning rollers, a breathable isolation belt, water-permeable holes, a scraper screen, and a lifting motor. The extension shells are positioned opposite each other on both sides of the water tank and connect to the recovery chamber. Each extension shell contains an inclined breathable isolation belt. The adjacent ends of two breathable isolation belts sink to the bottom center of the recovery chamber. The return hole is located below the breathable isolation belts. The ends of the two breathable isolation belts that are far apart extend to the outer side of the water surface in the tank. Water-permeable holes are distributed on the breathable isolation belts. Scrapers are evenly distributed on the outer surface of the breathable isolation belts. The lifting motor is installed on the outside of the extension shell. At least two positioning rollers are supported at both ends of the inner surface of the breathable isolation belts. The output shaft of the lifting motor is fixedly connected to the end of one of the positioning rollers. The *Trifolium repens* in the recovery chamber sinks with the water flow and is caught and carried out by the inclined breathable isolation belts, eliminating the need for manual retrieval and improving efficiency and safety.

[0024] Furthermore, the three-leaf ginseng cleaning device also includes a dynamic cleaning mechanism, which includes a slide, a turbulence plate, a spring, and a scraper. The slide is vertically slidably disposed on the side of the partition. One end of the slide is provided with a scraper that slides and fits against the return hole. The other end of the slide is fixed with an inclined turbulence plate. The lower end of the slide is connected to one end of the spring, and the other end of the spring is fixed to the bottom surface of the water tank.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: This *Trifolium repens* cleaning device has the following advantages:

[0026] 1. This *Trifolium repens* cleaning device allows the *Trifolium repens* to be processed to enter the cleaning cylinder, where the *Trifolium repens* is cleaned by the oscillation of the fluid, reducing damage to the leaves and ensuring that the subsequent products have good quality and shape, while also ensuring a certain level of processing efficiency.

[0027] 2. The side suction tank is periodically opened and closed by the opening and closing cover. The water flow on the outside periodically enters the inner side of the cleaning cylinder radially through the side suction tank, and collides with the axial fluid in the cleaning cylinder, causing the fluid to vibrate, thereby vibrating and cleaning the three leaves, which can ensure the efficiency and quality of cleaning.

[0028] 3. When the fluid passes through the conical orifice, diffusion and contraction occur, further creating turbulence in the water and improving the quality of cleaning.

[0029] 4. The hemispherical flow divider serves to guide the flow and reduce the impact on the clover during movement, greatly reducing damage.

[0030] 5. A recovery chamber lifting mechanism is installed to retrieve the cleaned *Trifolium repens* that has entered the recovery chamber, facilitating processing in the next step.

[0031] 6. A dynamic cleaning mechanism is set up. The water flow drives the turbulence plate and scraper to rise and fall, cleaning the return holes on the baffle plate, reducing the accumulation of blades or other debris near the return holes, and ensuring smooth water circulation.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-11 The present invention provides the following technical solution: a three-leaf ginseng cleaning device, comprising a water tank 1, a cleaning cylinder 2, an opening and closing cover 3, and a negative pressure pump 4;

[0046] The inner cavity of the water tank 1 is divided into a feeding chamber 102, a cleaning chamber 103 and a recovery chamber 104 by two partitions 101. The partitions 101 have a circular mounting hole in the middle and a return hole 105 on the lower side.

[0047] The cleaning cylinder 2 is installed inside the cleaning chamber 103. Its two ends are the inlet end and the outlet end, respectively, and both ends are connected to the circular mounting holes in the middle of the two partition plates 101. Side suction grooves are distributed on the side wall of the cleaning cylinder 2.

[0048] In one embodiment, the side suction groove is a strip-shaped hole 15, which is distributed at equal angles along the axis of the cleaning cylinder 2 and is parallel to the axis of the cleaning cylinder 2.

[0049] The *Trifolium repens* cleaning device also includes an inner isolation net 17, which is fixed to the inner wall of the cleaning cylinder 2 and covers all the side suction grooves; the inner isolation net 17 prevents *Trifolium repens* from passing through the side suction grooves during the vibration process;

[0050] In another embodiment, the side suction channel is composed of linearly distributed circular holes 16, the cross-section of which is conical; when the fluid passes through the conical circular holes 16, diffusion and contraction occur, further causing turbulence in the water and improving the cleaning quality.

[0051] The opening and closing cover 3 is located on the outside of the cleaning cylinder 2, and the side suction groove is opened and closed by rotation. The side wall of the opening and closing cover 3 is provided with connecting grooves 301. The side suction groove is opened and closed periodically by the opening and closing cover 3. The water flow on the outside periodically enters the inner side of the cleaning cylinder 2 radially through the side suction groove, and collides with the axial fluid inside the cleaning cylinder 2, causing the fluid to vibrate, thereby vibrating and cleaning the three leaves of the green leaf, which can ensure the efficiency and quality of cleaning.

[0052] The connecting groove 301 is strip-shaped, and the length direction of the connecting groove 301 is at an angle to the axis of the opening and closing cover 3. Adjacent connecting grooves 301 do not coincide in the cross-sectional direction. When the connecting groove 301 coincides with the side suction groove, the side suction groove is opened, and the water on the outside enters the cleaning cylinder 2 radially.

[0053] When the connecting channel 301 is tilted, its opening and closing time increases, making the fluid more stable when passing through. The connecting channel 301 can also be processed in a way that is parallel to the axis of the opening and closing cover 3.

[0054] The adjacent connecting grooves 301 do not overlap in the cross-sectional direction. The cross-section of the opening and closing cover 3 is circular. When viewed along the axial direction, the adjacent connecting grooves 301 do not overlap. This allows the side suction groove parallel to the axial direction to be in the adjacent connecting groove 301 at a certain moment. At this moment, the side suction groove and the connecting groove 301 are not connected, and the side suction groove is in a completely closed state.

[0055] The inner wall of the opening and closing cover 3 is provided with an annular groove, and a support bearing 5 is installed in the annular groove. The inner ring of the support bearing 5 is in contact with the outer wall of the cleaning cylinder 2. The end of the opening and closing cover 3 is also fixed with a flexible sealing ring 6 that is in contact with the outer wall of the cleaning cylinder 2. The support bearing 5 ensures that the opening and closing cover 3 rotates smoothly on the cleaning cylinder 2, and the flexible sealing ring 6 ensures the airtightness of the gap between the cleaning cylinder 2 and the opening and closing cover 3 when the side suction groove is in the closed state.

[0056] The negative pressure pump 4 is fixed to the discharge end of the cleaning cylinder 2 by a bracket. The inlet of the negative pressure pump 4 is provided with a flow divider 401. After the discharge end of the cleaning cylinder 2 is contracted, it covers the outside of the negative pressure pump 4. A flow gap for water supply and blade passage is reserved between the negative pressure pump 4 and the cleaning cylinder 2.

[0057] The flow divider 401 is hemispherical in shape and has a mesh for isolating blades in the middle. The concave surface of the flow divider 401 faces the negative pressure pump 4. The hemispherical flow divider 401 serves to guide the flow and at the same time reduces the impact on the three leaves during the movement, greatly reducing damage.

[0058] It also includes a pump drive mechanism, which includes a motor 7, a belt 8, and a connecting shaft 9. The motor 7 is mounted on the outer side of the water tank 1, and the connecting shaft 9 is rotatably connected to the inner wall of the water tank 1. The connecting shaft 9 is fixedly connected to the shaft of the negative pressure pump 4. Both the connecting shaft 9 and the output shaft of the motor 7 are equipped with pulleys, and the two pulleys are connected by the belt 8. In the specific working process, the motor 7 drives the connecting shaft 9 to rotate through the belt 8, and the connecting shaft 9 drives the negative pressure pump 4 to rotate. The negative pressure pump 4 can be a conventional impeller pump.

[0059] The *Trifolium repens* cleaning device also includes a rotating drive mechanism for opening and closing the cover. The rotating drive mechanism includes a reduction gearbox 10, a gear 11, and a gear ring 12. The reduction gearbox 10 is fixed to the side wall of the water tank 1. The input shaft of the reduction gearbox 10 is fixedly connected to the output shaft of the motor 7. The gear 11 is fixed on the output shaft of the reduction gearbox 10, and the gear ring 12 that meshes with the gear 11 is fixed on the opening and closing cover 3. In the specific working process, the motor 7 drives the reduction gearbox 10 to rotate, the reduction gearbox 10 drives the gear 11 to rotate, and then drives the opening and closing cover 3 to rotate through the cooperation with the gear ring 12.

[0060] A motor 7 drives the differential speed movement of the opening and closing cover 3 and the negative pressure pump 4, which facilitates control.

[0061] The three-leaf ginseng cleaning device also includes a drain pipe 13. A collection tank 14 is provided at the bottom of the water tank 1, which is connected to its inner cavity. The collection tank 14 is connected to the interface of the drain pipe 13. The drain pipe 13 is used to suck up the dirt deposited at the bottom of the water tank.

[0062] The *Trifolium repens* cleaning device also includes a recovery chamber lifting mechanism, which includes an extension shell 18, positioning rollers 19, a breathable isolation belt 20, water-permeable holes 21, a scraper 22, and a lifting motor 23. The extension shells 18 are arranged opposite each other on both sides of the water tank 1 and are connected to the recovery chamber 104. Each extension shell 18 is provided with an inclined breathable isolation belt 20. The adjacent ends of the two breathable isolation belts 20 sink to the bottom center of the recovery chamber 104. The return hole 105 is located below the breathable isolation belts 20. The ends of the two breathable isolation belts 20 that are far apart from each other extend to the outside of the water surface of the water tank 1. Water-permeable holes 21 are distributed on the breathable isolation belts 20. Scrapers 22 are evenly distributed on the outer surface of the breathable isolation belts 20. The lifting motor 23 is installed on the outside of the extension shell 18. There are at least two positioning rollers 19 and they are supported at both ends of the inner surface of the breathable isolation belts 20. The output shaft of the lifting motor 23 is fixedly connected to the end of one of the positioning rollers 19.

[0063] A recovery chamber lifting mechanism is set up to retrieve the three-leaf greens that have entered the recovery chamber 104 after cleaning, so as to facilitate the processing of the next process.

[0064] In the specific working process of the recovery chamber lifting mechanism: the lifting motor 23 is powered by an external power source. The rotation of the lifting motor 23 drives the positioning roller shaft 19 and the ventilated isolation belt 20 to rotate. Since the water flowing into the recovery chamber 104 needs to sink and pass through the water permeable hole 21 of the ventilated isolation belt 20, it flows back to the cleaning chamber 103 after descending to the return hole 105. Due to the sinking, the leek adheres to the upper side of the ventilated isolation belt 20. The ventilated isolation belt 20 drives the scraper 22 to move, and carries the cleaned leek out from the inside to the outside. A conveyor belt can be set below the expansion shell 18 to transport the carried-out leek to the next process.

[0065] It also includes a dynamic cleaning mechanism, which includes a slide 24, a turbulence plate 25, a spring 26, and a scraper 27. The slide 24 is vertically slidably disposed on the side of the partition 101. One end of the slide 24 is provided with a scraper 27 that slides and fits against the return hole 105. The other end of the slide 24 is fixed with an inclined turbulence plate 25. The lower end of the slide 24 is connected to one end of the spring 26, and the other end of the spring 26 is fixed to the bottom surface of the water tank 1.

[0066] The water at the bottom of the water tank 1 moves in the opposite direction along the recovery chamber - cleaning chamber - feeding chamber. The turbulence plate 25 is specifically installed such that the end of the turbulence plate 25 near the feeding chamber is higher than the other end. When the water flows laterally, it applies downward pressure to the inclined surface of the turbulence plate 25.

[0067] In the specific working process of the dynamic cleaning mechanism: the water flows in the feed chamber 102, the cleaning chamber 103 and the recovery chamber 104. When it passes the inclined turbulence plate 25, it applies downward pressure, causing the scraper 27 to move downward. At this time, the spring 26 is compressed. Due to the fluctuation of the fluid in the cleaning chamber 103, the spring 26 deforms and recovers when the pressure decreases, and the scraper 27 rises and resets. During the rising and falling process of the scraper 27, the return hole 105 is cleaned. The water flow drives the turbulence plate 25 and the scraper 27 to rise and fall, which cleans the return hole 105 on the baffle 101, reduces the accumulation of blades or other debris near the return hole 105, and ensures smooth water circulation.

[0068] The working principle of the *Trifolium repens* cleaning device provided by this invention is as follows:

[0069] Water tank 1 is filled with water, and the water completely covers the entire cleaning drum 2;

[0070] The pump drive mechanism drives the impeller inside the negative pressure pump 4 to rotate, which reduces the pressure on one side of the cleaning cylinder 2. This occurs when the side suction trough is completely closed. Figure 7 As shown, at this time, the side suction groove and the connecting groove 301 are not connected. The water in the feeding chamber 102 enters through the feeding end of the cleaning cylinder 2 and moves radially towards the discharge end of the cleaning cylinder 2.

[0071] As the discharge end of the cleaning cylinder 2 contracts and covers the outside of the negative pressure pump 4, the inner diameter of the discharge end is reduced. Most of the fluid is drawn to the outside of the cleaning cylinder 2 by the negative pressure pump 4 through the diversion cover 401. The flow velocity of the central part of the discharge end of the cleaning cylinder 2 is high corresponding to the negative pressure pump. The other part of the fluid is carried out from the water supply flow between the negative pressure pump 4 and the cleaning cylinder 2 and the flow gap through which the blades pass. The fluid that enters the recovery chamber 104 is reversed and replenished to the cleaning chamber 103 and the feeding chamber 102 through the return hole 105.

[0072] The rotating drive mechanism of the opening and closing hood drives the opening and closing hood to rotate outside the cleaning cylinder 2, causing the side suction groove and the connecting groove 301 to periodically connect, realizing the conversion of the side suction groove to fully closed, half-open, or fully open. When the side suction groove is a strip-shaped hole 15, it can completely overlap with the connecting groove 301 and be in a fully open state. During the opening process, if... Figure 8 As shown, the water flow periodically passes through the side suction groove and enters the inner side of the cleaning cylinder 2 radially, colliding with the axial fluid inside the cleaning cylinder 2, causing the fluid to oscillate.

[0073] During the cleaning process, the *Trifolium repens* to be processed is placed in the feeding chamber 102 and drawn into the cleaning cylinder 2 by the fluid through the feeding end. It is then impacted by the oscillating fluid to remove the dust from the surface of the *Trifolium repens*. The *Trifolium repens* moves to the right and is diverted to the edge by the diversion hood 401. It is carried out to the recovery chamber 104 through the outflow gap. The cleaned *Trifolium repens* is blocked in the recovery chamber 104 and can then be retrieved.

[0074] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
