Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine cleaning, and in particular to a cleaning device for traditional Chinese medicine raw materials. Background Art

[0002] In the field of Chinese medicinal materials processing, the cleaning process before drying is crucial. At present, a variety of cleaning devices have been applied in actual production. Common ones include drum-type cleaning equipment, which uses the rotation of the drum and the mutual friction between the water flow and the medicinal materials to remove surface dirt; and spray-type cleaning devices, which use high-pressure water flow to flush and clean the medicinal materials. These existing technologies have met the needs of Chinese medicinal materials cleaning to a certain extent, improved the cleaning efficiency, and can remove dust, dirt and other impurities on the surface of most medicinal materials.

[0003] However, with the continuous improvement of the quality requirements for Chinese medicinal materials, the limitations of existing cleaning devices have gradually become apparent. Some Chinese medicinal materials are in increasing demand in the market due to their unique medicinal value, and these medicinal materials are often brittle. For example, some rhizomes and petals of medicinal materials are prone to collision with these components during the operation of traditional cleaning equipment due to the structural design of equipment components, such as the stirring blades inside the drum, the position of the nozzles of the spray device, and the impact angle of the water flow. This physical effect may cause breakage or damage to fragile medicinal materials, thereby affecting the integrity and quality of the medicinal materials, and further reducing their medicinal value and market price.

[0004] Referring to the Chinese patent document with announcement number CN118180011B and announcement date July 26, 2024, entitled "A device for cleaning rhizomes of Chinese medicinal materials", a brush roller that can be adjusted horizontally and vertically is used to make the distance between two adjacent brush rollers adjustable to meet the cleaning needs of different rhizomes of Chinese medicinal materials.

[0005] Referring to the above technical solution, during the cleaning process, when the brittle medicinal materials are cleaned by the brush roller type cleaning device, due to the rotation of the brush roller and the impact of the water flow inside the device, the medicinal materials are easily hooked with the brush roller, the inner wall of the device and other parts. This hooking and collision may have little effect on tough medicinal materials, but for brittle medicinal materials, it may cause breakage or damage. Although the existing manual cleaning can reduce the breakage of brittle Chinese medicinal materials, the efficiency of manual cleaning is slow and it is difficult to meet the needs of large-scale Chinese medicine processing. Summary of the invention

[0006] In view of this, the present invention provides a cleaning device for Chinese medicine raw materials, which avoids direct collision between brittle medicinal materials and cleaning components during the cleaning process, thereby reducing the possibility of brittle medicinal materials being broken or damaged during the cleaning process.

[0007] In order to solve the above technical problems, the present invention provides a cleaning device for Chinese medicine raw materials, comprising a cleaning tank with an opening at the top and a fixed frame arranged on the cleaning tank, the fixed frame is provided with a linear drive and a driving mechanism, the execution end of the linear drive is connected with a cleaning mechanism that slides vertically with the fixed frame, the cleaning mechanism comprises a flushing component and a decontamination component driven by the driving mechanism; the flushing component comprises a spray rod that rotates eccentrically in the cleaning tank, and a spray head is arranged on the peripheral wall of the spray rod; the decontamination component comprises a cleaning cylinder that is arranged between the outer wall of the spray rod and the inner wall of the cleaning tank and performs planetary motion, the cleaning cylinder is used to place the Chinese medicine raw materials to be cleaned, the peripheral wall of the cleaning cylinder is provided with a water inlet hole, and the bottom wall of the cleaning cylinder is vertically slidably connected with a cleaning member; a baffle is provided in the cleaning cylinder to prevent the cleaning member from directly contacting with the Chinese medicine raw materials, and a plurality of water permeable holes are provided on the baffle; the cleaning member comprises a floating plate and a rotating seat arranged on the upper end surface of the floating plate, a suction column is rotatably arranged on the rotating seat, and a suction and discharge hole is downwardly penetrated through the upper end surface of the suction column.

[0008] By adopting the above technical scheme, the linear drive drives the cleaning mechanism to enter the cleaning tank containing cleaning liquid, and makes the cleaning liquid cover the cleaning cylinder. The spray rod performing eccentric motion can stir the cleaning liquid in the cleaning tank, and the spray head can jet clean the Chinese medicine raw materials in the cleaning cylinder; the linear drive drives the cleaning mechanism to slide back and forth vertically periodically, so that the floating plate is affected by the resistance of the cleaning liquid, and drives the rotating suction column to spray cleaning liquid into the cleaning cylinder or suck impurities in the cleaning cylinder; the cleaning cylinder performing planetary motion enables cleaning liquid in different directions to enter the cleaning cylinder from the water inlet, so that the Chinese medicine in the cleaning cylinder is flushed by the cleaning liquid at multiple angles; the spray rod performing eccentric rotation collides with the outer wall of the cleaning cylinder, and shakes off the impurities blocked in the water inlet to avoid blockage of the water inlet.

[0009] Optionally, a piston sleeve is provided on the bottom wall of the cleaning cylinder; and a piston disc matched with the piston sleeve is provided between the floating disc and the rotating seat.

[0010] By adopting the above technical solution, when the floating disc moves away from the cleaning cylinder, a greater pressure difference can be generated between the piston disc and the cleaning cylinder, forming a strong suction force inside the cleaning cylinder. Impurities in the cleaning cylinder, whether they are soil particles and dust mixed into the cleaning liquid by the Chinese medicinal materials themselves, or small attachments that fall off the surface of the Chinese medicinal materials during the cleaning process, are affected by this suction force and are sucked out of the cleaning cylinder; at the same time, when the floating disc moves toward the cleaning cylinder, the space between the floating disc and the piston sleeve is compressed, and the compressed cleaning liquid is ejected from the suction and discharge holes, so that the floating disc can spray more cleaning liquid through the suction and discharge holes at a higher speed to the Chinese medicinal materials in the cleaning cylinder, which is convenient for the impurities on the surface of the Chinese medicinal materials to be separated.

[0011] Optionally, the cleaning component also includes a sliding disk adapted to the inner wall of the cleaning cylinder, the sliding disk being provided with a rotating hole, and the upper part of the suction column being rotatably connected to the rotating hole; the outer wall of the sliding disk being provided with a first sliding groove, and the inner wall of the cleaning cylinder being provided with a sliding block adapted to the first sliding groove; the bottom wall of the cleaning cylinder being provided with a sliding hole adapted to the suction column, the suction column being provided with a spiral groove, and a convex pin slidably connected to the spiral groove being fixedly provided on the wall of the sliding hole; a cavity being provided at the upper part of the suction column, and the interior of the cavity being filled with a plurality of steel balls.

[0012] By adopting the above technical scheme, when the floating plate moves away from the cleaning cylinder, the spiral groove drives the suction column to rotate during the movement through the convex pin, so that the steel balls in the suction column cavity collide with each other to generate vibration, and the vibration is transmitted to the suction and discharge hole, so that the impurities in the suction and discharge hole are shaken, and the impurities in the suction and discharge hole are flushed out in cooperation with the water flow discharged outward, so as to avoid the blockage of the suction and discharge hole; the floating plate will generate vibration during the reciprocating motion, and the vibration is transmitted to the Chinese medicine raw material through the wall of the cleaning cylinder and the floating plate. On the basis of the impact force of the cleaning liquid, the vibration can further destroy the adhesion between the dirt and the depressed parts of the medicinal material, so that the dirt in the parts that are difficult to be washed by the jet can fall off from the depressed parts of the medicinal material, and then after being flushed by the water flow, the dirt in the parts that are difficult to be washed by the jet can finally be separated; at the same time, in the process of the floating plate driving the suction column to spray water to the cleaning cylinder, the rotating suction column makes the flow of the cleaning liquid rushing to the cleaning cylinder become turbulent.

[0013] Optionally, the driving mechanism includes a driving motor arranged on a fixed frame and a planetary gear set rotatably connected to the fixed frame, the planetary gear set includes a transmission shaft rotatably connected to the fixed frame, a turntable and a sun gear are coaxially fixed on the transmission shaft, a planetary gear meshing with the sun gear is rotatably connected to the turntable; the fixed frame is also slidably connected to a ring gear meshing with the planetary gear; the driving motor output shaft is provided with a first bevel gear, a second bevel gear meshing with the first bevel gear is rotatably provided on the fixed frame, and the second bevel gear is coaxial with the transmission shaft.

[0014] Optionally, a connecting rod is coaxially arranged on the lower end surface of the planetary gear, and the connecting rod is fixedly connected to the upper end surface of the cleaning cylinder.

[0015] Optionally, a first dovetail groove is provided on the lower end face of the sun gear, a first dovetail block matching the first dovetail groove is provided on the upper end face of the spray rod, and compression springs are provided on the two side walls of the first dovetail groove opposite to the movement direction of the first dovetail block; an eccentric block is provided on the spray rod.

[0016] Optionally, the linear drive adopts a cylinder, an annular dovetail block is provided on the telescopic shaft of the cylinder, a bearing is provided on the transmission shaft, a driving rod is provided on the outer wall of the bearing, one end of the driving rod is fixedly connected to the bearing, and the other end is fixedly connected to the end face of the gear ring; an annular dovetail groove matching the annular dovetail block is provided on the bearing, and the annular dovetail block is slidably connected to the annular dovetail groove; a sliding key is provided on the peripheral wall of the transmission shaft, and a second sliding groove matching the sliding key is provided on the second bevel gear.

[0017] By adopting the above technical solution, the driving motor drives the second bevel gear to rotate through the meshing of the first bevel gear, so that the transmission shaft drives the turntable and the sun gear to rotate. Since the ring gear is slidably connected to the fixed frame and is restricted by the fixed frame, the ring gear will not rotate, and the transmission shaft drives the sun gear to revolve around its own axis. The transmission shaft drives the planetary gear to perform planetary motion through the turntable, and the planetary gear then drives the cleaning cylinder to perform planetary motion through the connecting rod. When the cleaning cylinder needs to be moved vertically periodically, since the cylinder is slidably connected to the bearing through the annular dovetail block, the cylinder can drive the transmission shaft to reciprocate up and down through the bearing. Since the turntable is coaxially fixedly connected to the transmission shaft, the ring gear is fixedly connected to the bearing through the driving rod, and the ring gear is slidably connected to the fixed frame, the up and down movement of the transmission shaft will simultaneously drive the planetary gear set and the spray rod to move up and down.

[0018] Optionally, a discharge port is provided on the upper end surface of the cleaning cylinder, and a hinged cover capable of opening and closing the discharge port is provided on the discharge port.

[0019] Optionally, the spray rod is a hollow structure with an opening at the bottom, and the bottom of the spray rod is connected to a hose via a rotating joint, and the hose is connected to a water supply pump outside the cleaning tank.

[0020] Optionally, a drain outlet is provided at the bottom of the cleaning tank, the drain outlet is connected to a circulation filtering device outside the cleaning tank, and the circulation filtering device is connected to a water supply pump.

[0021] By adopting the above technical solution, when it is necessary to load and unload the Chinese medicinal materials in the cleaning cylinder, the cleaning tank is removed from the cleaning cylinder by the linear drive, the hinged cover is opened, and the operator puts or takes out the Chinese medicinal materials from the cleaning cylinder, and then closes the hinged cover. The water supply pump pumps the cleaning liquid into the spray rod through the hose pump, and then sprays it into the cleaning cylinder through the spray head on the spray rod, thereby forming a jet cleaning of the Chinese medicinal materials inside the cleaning cylinder. Since the spray rod rotates irregularly eccentrically under the drive of the sun gear, a rotating joint is used to connect the hose to the bottom of the spray rod, thereby preventing the rotation of the spray rod from causing twisting of the hose. During cleaning, the cleaning liquid inside the cleaning tank gradually becomes dirty as the cleaning proceeds. By connecting the cleaning tank with the circulating filter device, the cleaning liquid inside the cleaning tank can be filtered in real time, thereby reducing the secondary contamination of the Chinese medicinal materials by the cleaning liquid.

[0022] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. During cleaning, the present invention puts the Chinese medicinal materials into a cleaning cylinder that performs planetary motion, so that the Chinese medicinal materials are rinsed by cleaning liquid at multiple angles, ensuring that all parts of the surface of the Chinese medicinal materials can be cleaned; the spray rod rotates eccentrically, and its spray head can perform jet cleaning on the Chinese medicinal materials in the cleaning cylinder, and the eccentrically rotating spray rod can also knock on the cleaning cylinder, so that impurities in the water inlet hole of the cleaning cylinder are separated from the water inlet hole, thereby avoiding clogging of the water inlet hole; at the same time, the design of the cleaning cylinder can avoid direct collision between the medicinal materials and the cleaning components, reduce the situation of brittle medicinal materials being broken or damaged during the cleaning process, protect the integrity of the medicinal materials to the greatest extent, and thus ensure the medicinal value and market price of the medicinal materials.

[0023] 2. The present invention cooperates with the floating plate, the piston plate and the piston sleeve. When the floating plate moves in the opposite direction to the cleaning cylinder, a pressure difference is generated between the piston plate and the cleaning cylinder, and the impurities in the cleaning cylinder are sucked out by the pressure difference; when the floating plate moves toward the cleaning cylinder, the rotating suction column will generate turbulent cleaning liquid to spray toward the Chinese medicine raw materials, which is convenient for the impurities to be separated. In addition, when the suction column rotates, the steel balls in its cavity collide with each other to generate vibration, which is transmitted to the suction and discharge holes, causing the impurities in the suction and discharge holes to shake and be discharged outward through the suction and discharge holes, which can avoid the blockage of the suction and discharge holes. At the same time, the vibration can also produce a slight shaking effect on the medicinal materials in the cleaning cylinder, so that the dirt in the parts that are difficult to wash with water flow is loosened and falls off, and the dirt that falls off is discharged after being washed by water flow, further improving the decontamination effect.

Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

The linear drive 3 drives the cleaning mechanism to enter the cleaning tank 1 so that the cleaning liquid covers the cleaning cylinder 61; the driving mechanism 4 drives the spray rod 51 to rotate eccentrically, so that the spray rod 51 can perform jet cleaning on the Chinese medicinal material in the cleaning cylinder 61; The linear drive 3 drives the cleaning mechanism to slide vertically back and forth periodically. When the linear drive 3 drives the cleaning cylinder 61 and the floating plate 64 to move downward, the floating plate 64 is pushed downward by the resistance of the cleaning liquid, and the floating plate 64 drives the suction column 66 to move toward the cleaning cylinder 61. The floating plate 64 pushes the cleaning liquid at the bottom of the cleaning cylinder 61 toward the cleaning cylinder 61, and the cleaning liquid enters the cleaning cylinder 61 through the suction and discharge holes 67 on the suction column 66, thereby jet cleaning the Chinese medicine raw materials in the cleaning cylinder 61; When the linear actuator 3 drives the cleaning cylinder 61 and the floating plate 64 to move upward, the floating plate 64 is affected by the resistance of the cleaning liquid upward, and the floating plate 64 drives the suction column 66 to move downward. The floating plate 64 generates negative pressure downward, so that a pressure difference is generated between the inside of the cleaning cylinder 61 and the floating plate 64. The cleaning liquid carrying impurities in the cleaning cylinder 61 is discharged from the cleaning cylinder 61 through the suction and discharge holes 67 under the action of the negative pressure. The cleaning cylinder 61 that performs planetary motion allows cleaning liquids in different directions to enter the cleaning cylinder 61 from the water inlet 62, thereby allowing the Chinese medicine in the cleaning cylinder 61 to be washed by the cleaning liquids at multiple angles; At the same time, the eccentrically rotating spray rod 51 collides with the outer wall of the cleaning cylinder 61, and the impurities blocked in the water inlet hole 62 are shaken off, so as to prevent the impurities from adhering to the water inlet hole 62 due to the centrifugal force when the cleaning cylinder 61 performs planetary motion, thereby affecting the cleaning of the Chinese medicine raw materials in the cleaning cylinder 61; The jet sprayed from the spray head 52 can also wash away the impurities around the floating plate 64, thereby preventing the floating plate 64 from spraying the cleaned impurities back into the cleaning cylinder 61.

On the basis of the impact force of the cleaning liquid, the vibration can further destroy the adhesion between the dirt and the sunken parts of the medicinal materials, so that the dirt in the parts that are difficult to be washed by the jet can fall off from the sunken parts of the medicinal materials, and then after being flushed by the water flow, the dirt in the parts that are difficult to be washed by the jet can finally be separated.

Since the ring gear 46 is slidably connected to the fixed frame 2 and is restricted by the fixed frame 2, the ring gear 46 will not rotate, and the transmission shaft 42 drives the sun gear 44 to revolve around its own axis. The transmission shaft 42 drives multiple planetary gears 45 to perform planetary motion through the turntable 43.

[0037] The implementation principle of a cleaning device for Chinese medicine raw materials in an embodiment of the present invention is as follows: When the Chinese medicine raw materials need to be cleaned, the discharge port on the cleaning cylinder 61 is opened, the medicinal materials are placed in the cleaning cylinder 61, and then the hinged cover 611 is closed; sufficient cleaning liquid is poured into the cleaning tank 1; Start the cylinder 31, and the telescopic shaft of the cylinder 31 pushes the transmission shaft 42 to slide downward through the bearing 33, so that the cleaning cylinder 61 is completely immersed in the cleaning liquid; The driving motor 41 is started. The driving motor 41 drives the second bevel gear 48 to rotate through the meshing of the first bevel gear 47, so that the transmission shaft 42 drives the rotating disk 43 and the sun gear 44 to rotate. Since the ring gear 46 is slidably connected with the fixing frame 2 and is restricted by the fixing frame 2, the ring gear 46 will not rotate, and the transmission shaft 42 drives the sun gear 44 to perform orbital motion about its own axis. The transmission shaft 42 drives the plurality of planetary gears 45 to perform planetary motion through the rotating disk 43, and each planetary gear drives the corresponding cleaning cylinder 61 to perform planetary motion through the connecting rod 49; the cleaning cylinder 61 performing planetary motion allows cleaning liquids in different directions to enter the cleaning cylinder 61 from the water inlet 62, so that the Chinese medicine in the cleaning cylinder 61 is cleaned by the jets of cleaning liquids at multiple angles; Since the spray rod 51 is slidably connected with the sun gear 44 and an eccentric block is provided on the spray rod 51, when the sun gear 44 drives the spray rod 51 to rotate, the spray rod 51 will rotate eccentrically, so that the first dovetail block 442 moves back and forth in the first dovetail groove 441; the eccentrically rotating spray rod 51 collides with the outer wall of the cleaning cylinder 61, and the impurities blocked in the water inlet hole 62 are shaken off, so as to prevent the impurities from being attached to the water inlet hole 62 by the centrifugal force when the cleaning cylinder 61 performs planetary motion, thereby affecting the cleaning of the Chinese medicine raw materials in the cleaning cylinder 61; At this time, the cylinder 31 starts to drive the cleaning cylinder 61 to perform periodic vertical sliding. When the linear actuator 3 drives the cleaning cylinder 61 and the floating plate 64 to move downward, the floating plate 64 is pushed downward by the resistance of the cleaning liquid, and the floating plate 64 drives the suction column 66 to move toward the cleaning cylinder 61. The floating plate 64 pushes the cleaning liquid at the bottom of the cleaning cylinder 61 toward the cleaning cylinder 61. The spiral groove 633 drives the suction column 66 to rotate during the movement through the convex pin. The cleaning liquid enters the cleaning cylinder 61 through the suction and discharge holes 67 on the suction column 66. The rotating suction column 66 makes the water flow entering the cleaning cylinder 61 turbulent, thereby performing jet cleaning on the Chinese medicine raw materials in the cleaning cylinder 61. When the linear actuator 3 drives the cleaning cylinder 61 and the floating plate 64 to move upward, the floating plate 64 is affected by the resistance of the cleaning liquid, and the floating plate 64 drives the suction column 66 to move downward. The floating plate 64 generates negative pressure downward, so that a pressure difference is generated between the cleaning cylinder 61 and the floating plate 64. The cleaning liquid carrying impurities in the cleaning cylinder 61 is discharged from the cleaning cylinder 61 through the suction and discharge hole 67 under the action of the negative pressure; while the floating plate 64 drives the suction column 66 to move downward, the spiral groove 633 drives the suction column 66 to rotate during the movement through the convex pin, so that the steel balls 634 in the cavity of the suction column 66 collide with each other to generate vibration, and the vibration is transmitted to the suction and discharge hole 67, so that the impurities in the suction and discharge hole 67 are shaken, and the impurities in the suction and discharge hole 67 are flushed out in cooperation with the water flow discharged outward, so as to avoid clogging of the suction and discharge hole 67; At the same time, the vibration is transmitted to the Chinese medicine raw material through the wall of the cleaning cylinder 61 and the floating plate 64. On the basis of the impact force of the cleaning liquid, the vibration can further destroy the adhesion between the dirt and the concave part of the medicine, so that the dirt in the part that is difficult to be washed by the jet can fall off from the concave part of the medicine, and then after being flushed by the water flow, the part that is difficult to be washed by the jet can be finally cleaned; The jet ejected from the spray head 52 can also wash away the impurities around the floating plate 64, and cooperate with the cleaning cylinder 61 that performs planetary motion, so as to prevent the floating plate 64 from spraying the cleaned impurities back to the cleaning cylinder 61; the water in the cleaning tank 1 is discharged into the circulation filter device through the drain port 11, and after being filtered by the circulation filter device, it is re-input into the inner cavity of the spray rod 51 through the water supply pump.
