Description

Technical Field

[0001] This utility model relates to the field of medicine washing machine technology, and more specifically, to a medicine washing machine. Background Technology

[0002] A medicine washing machine is a device used to clean medicinal materials. It is mainly used to remove mud, sand, impurities and bacteria from the surface of the medicinal materials. The medicine washing machine usually consists of a mechanical transmission system composed of a motor, a reducer and other components, which drives the cylinder to rotate slowly along the horizontal axis. The directional guide plate inside the cylinder pushes the material from one end to the other end. At the same time, water from the water tank is pressurized by a high-pressure water pump and sprayed out from the spray pipe. The scouring force of the water and the friction of the rolling of the material are used to remove the impurities from the surface of the material.

[0003] However, existing washing machines for medicinal herbs have water spray pipes inside the washing drum. The water spray pipes spray water onto the inner wall of the washing drum to wash the medicinal herbs. However, the number of spray nozzles that can be installed on the water spray pipes is relatively small, which can easily lead to incomplete cleaning of the medicinal herbs, leaving mud or impurities on the surface. Furthermore, the medicinal herbs are prone to collision and compression with the inner wall of the washing drum during the rolling process, which can easily cause damage and severe peeling of the medicinal herbs. Utility Model Content

[0004] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, one objective of the present invention is to provide a washing machine that can significantly improve the cleaning effect and reduce damage and peeling of medicinal materials.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A medicine washing machine, comprising: frame; A chassis, which is fixedly mounted on the frame; A cleaning cylinder is rotatably placed inside the housing, and multiple brush assemblies are regularly arranged on the inner wall of the cleaning cylinder; the cleaning cylinder is provided with multiple drainage holes arranged in a row. A drive device is fixedly placed inside the frame, and the output end of the drive device is connected to the cleaning cylinder, which drives the cleaning cylinder to rotate. A water inlet pipe, one end of which is connected to an external water source, and the other end of which extends into the cleaning drum; Multiple water spray pipes are provided, all of which are encircled on the outer wall of the cleaning cylinder. Each of the multiple water spray pipes is provided with multiple water spray holes, and the multiple water spray holes spray water into the cleaning cylinder through some of the drain holes. A water supply pipe, one end of which is connected to the water inlet pipe via a rotary joint, and the other end of which is connected to a plurality of water spray pipes in sequence.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the driving device includes: An electric motor is fixedly mounted on the frame, and a first pulley is connected to the output end of the motor. A toothed ring, which is fixedly fitted onto the cleaning cylinder; A drive gear meshes with the gear ring; the drive gear is connected to a second pulley, and the drive gear and the second pulley are rotatably mounted on the frame; the second pulley is connected to the first pulley via a belt; A driven gear is rotatably mounted on the frame and meshes with the gear ring.

[0008] Furthermore, the driving device also includes: A limiting protrusion ring is fixedly fitted onto the cleaning cylinder; Two rollers are rotatably mounted on the frame; each roller has a V-groove that engages with the limiting protrusion.

[0009] Furthermore, it also includes: A drain pipe is fixedly placed inside the frame, with one end of the drain pipe connected to the bottom of the chassis and the other end connected to an external water storage device.

[0010] Furthermore, a feeding port communicating with one end of the cleaning cylinder is provided on one side wall of the casing, and a discharge port communicating with the other end of the cleaning cylinder is provided on the other end of the casing.

[0011] Furthermore, it also includes: The controller is fixedly mounted on the chassis and is electrically connected to the drive device.

[0012] Furthermore, it also includes: multiple guide plates, which are arranged in a spiral shape on the inner wall of the cleaning cylinder.

[0013] The beneficial effects of this invention are as follows: The medicinal materials are cleaned using a combination of brush friction and spraying.

The direction of the high-pressure water spray is consistent with the brushing direction of the brush assembly, allowing for brushing and rinsing of the same end face of the medicinal materials, further enhancing the cleaning effect. During the tumbling process of the medicinal materials inside the cleaning cylinder, the high-pressure water impacts the materials, reducing the force of collisions with the cleaning cylinder and mitigating the impact and compression between the materials and the cleaning cylinder, thereby reducing damage and peeling of the medicinal materials.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] like Figures 1 to 7 As shown, a medicine washing machine includes: Rack 1; Chassis 2, which is fixedly mounted on the frame 1; A cleaning cylinder 3 is rotatably placed inside the housing 2. Multiple brush assemblies 4 are regularly arranged on the inner wall of the cleaning cylinder 3. Multiple drainage holes 5 are arranged on the cleaning cylinder 3. A drive device 6 is fixedly placed inside the frame 1. The output end of the drive device 6 is connected to the cleaning cylinder 3, and the drive device 6 drives the cleaning cylinder 3 to rotate. Water inlet pipe 7, one end of which is connected to an external water source, and the other end of which extends into the cleaning cylinder 3; Multiple water spray pipes 8 are all surrounding the outer wall of the cleaning cylinder 3. Multiple water spray holes 9 are provided on the multiple water spray pipes 8. The multiple water spray holes 9 spray water into the cleaning cylinder 3 through part of the drain holes 5. Water supply pipe 10, one end of which is connected to water inlet pipe 7 via rotary joint 11, and the other end is connected to multiple water spray pipes 8 in sequence.

[0018] In practical application, the medicinal materials to be cleaned are put into the cleaning cylinder 3, and the driving device 6 drives the cleaning cylinder 3 to rotate. The brush assembly 4 on the inner wall of the cleaning cylinder 3 rotates with the cleaning cylinder 3, generating friction with the surface of the medicinal materials to remove mud, impurities and attached microorganisms, especially for stubborn dirt in crevices. Water from an external source is delivered through the water inlet pipe 7, which is connected to the water supply pipe 10 via a rotary joint 11. The water flow is then diverted through the water supply pipe 10 to multiple spray pipes 8 surrounding the outer wall of the cleaning cylinder 3. The spray holes 9 on the spray pipes 8 spray water into the cleaning cylinder 3 through the drain hole 5 of the cleaning cylinder 3, forming a high-pressure spraying effect to further rinse the medicinal materials and wash away the impurities attached to the brush assembly 4.

[0019] This embodiment employs a dual cleaning method of brush friction and spraying to clean medicinal materials. The brush assembly 4 can thoroughly clean stubborn impurities in the folds and crevices of the medicinal materials, while the water spray from the water pipe 8 can rinse the materials from all directions, significantly improving the cleaning effect and reducing residual impurities on the surface of the medicinal materials. In addition, the spray holes 9 of the water pipe 8 spray high-pressure water into the cleaning cylinder 3 through the drain holes 5 of the cleaning cylinder 3. The spray direction of the high-pressure water is consistent with the brushing direction of the brush assembly 4, brushing and rinsing the same end face of the medicinal materials, further improving the cleaning effect. During the tumbling process of the medicinal materials in the cleaning cylinder 3, the high-pressure water impacts the medicinal materials, reducing the force of the medicinal materials colliding with the cleaning cylinder 3, slowing down the collision and squeezing between the medicinal materials and the cleaning cylinder 3, thereby reducing damage and peeling of the medicinal materials.

[0020] In the above embodiments, the driving device 6 includes: Motor 601, which is fixedly mounted on the frame 1, and the output end of motor 601 is connected to a first pulley 602; Gear ring 603, which is fixedly fitted onto the cleaning cylinder 3; A drive gear 604 meshes with a gear ring 603; the drive gear 604 is connected to a second pulley 605, and the drive gear 604 and the second pulley 605 are rotatably mounted on the frame 1; the second pulley 605 is connected to the first pulley 602 via a belt. A passive gear 606 is rotatably mounted on the frame 1 and meshes with the gear ring 603.

[0021] In practical applications, after the motor 601, fixed on the frame, starts, its output drives the first pulley 602 to rotate, and transmits power to the second pulley 605 through the belt, realizing the first step of deceleration or acceleration of power. The second pulley 605 is coaxially fixed with the drive gear 604, so the drive gear 604 rotates synchronously with the second pulley 605. Since the drive gear 604 meshes with the gear ring 603 fixedly mounted on the cleaning cylinder 3, the power is transmitted to the gear ring 603 through the drive gear 604, directly driving the cleaning cylinder 3 to rotate. The driven gear 606 meshes with the gear ring 603 and is rotatably mounted on the frame 1. Its function is to support the gear ring 603 from the other side, balance the radial force generated when the drive gear 604 transmits power, and prevent the gear ring 603 from tilting or wearing due to excessive force on one side, ensuring that the rotation of the cleaning cylinder 3 is stable and highly concentric.

[0022] This embodiment employs a combination of belt drive and gear meshing: belt drive can buffer the impact during motor startup, reducing vibration and noise; the meshing transmission between the drive gear 604 and the gear ring 603 ensures precise and efficient power transmission, avoids slippage, and ensures stable rotation speed of the cleaning drum 3; the drive gear 604 and the driven gear 606 mesh with the gear ring 603 from both sides, forming symmetrical support, effectively offsetting the unilateral force when the gear ring 603 rotates, reducing the wear rate of the gear ring 603 and the drive gear 604, and extending the service life of the equipment, which is especially suitable for scenarios where the cleaning drum 3 is loaded with a large amount of medicinal materials.

[0023] In the above embodiments, the driving device 6 further includes: A limiting protrusion ring 607 is fixedly fitted onto the cleaning cylinder 3; Two rollers 608 are rotatably mounted on the frame 1; each of the two rollers 608 is provided with a V-groove, and the V-groove on each of the two rollers 608 engages with the limiting protrusion ring 607.

[0024] In practical applications, the limiting protrusion 607, which is fixedly fitted on the cleaning cylinder 3, is embedded in the V-groove of the two rollers 608 and forms a meshing. The two inclined surfaces of the V-groove are in contact with the outer peripheral surface of the limiting protrusion 607, which on the one hand restricts the axial movement of the cleaning cylinder 3 during rotation, and on the other hand helps to constrain the radial offset, complementing the support of the gear ring 603 by the driving gear 604 and the driven gear 606. When the cleaning cylinder 3 rotates, the limiting protrusion 607 drives the two rollers 608 to rotate synchronously. By replacing sliding friction with rolling friction, it avoids generating additional resistance to the rotation of the cleaning cylinder 3 and can continuously provide stable support force, ensuring that the cleaning cylinder 3 always maintains concentric rotation.

[0025] In this embodiment, the driving gear 604 and the driven gear 606 mainly transmit power and provide partial radial support through the gear ring 603. The combination of the limiting convex ring 607 and the roller 608 further strengthens the constraint from the axial and radial directions. It is especially suitable for the washing cylinder 3 when the center of gravity shifts due to uneven loading of medicinal materials, which can effectively suppress shaking or swaying and ensure that the brush assembly 4 and the medicinal materials are rubbed evenly and the spray position is accurate. The meshing contact area of ​​the V-groove and the limiting convex ring 607 is large, and the force is distributed, which can reduce the pressure on a single support point. At the same time, the resistance of rolling friction is much smaller than that of sliding friction, which can reduce the wear rate of the limiting convex ring 607 and the roller 608. Combined with the balanced force design of the gear transmission, it further extends the overall service life of the equipment. When the loading of medicinal materials in the washing cylinder 3 changes or rotates, an impact is generated. The rigid limiting of the limiting convex ring 607 and the roller 608 can quickly absorb part of the impact force, avoiding tooth surface damage at the meshing part of the gear ring 603 and the gear due to excessive instantaneous force, thus improving the reliability of the equipment under high load and continuous operation scenarios.

[0026] The above embodiments also include: Drain pipe 12 is fixedly placed inside the frame 1. One end of the drain pipe 12 is connected to the bottom of the housing 2, and the other end of the drain pipe 12 is connected to an external water storage device.

[0027] In practical applications, the wastewater generated during the cleaning process first flows into the casing 2 through the drain hole 5 on the cleaning cylinder 3, and then collects at the bottom of the casing 2. Since one end of the drain pipe 12 is connected to the bottom of the casing 2 and the other end is connected to the external water storage device, the wastewater will naturally flow along the drain pipe 12 and finally be discharged into the external equipment, thus completing the orderly collection and treatment of wastewater.

[0028] In this embodiment, the drain pipe 12 is directly connected to the bottom of the chassis 2, which can completely drain the sewage collected inside the chassis 2, avoid sewage residue in the corners of the chassis 2, and reduce the risk of bacterial growth and internal corrosion of the equipment.

[0029] In the above embodiment, a feeding port 13 communicating with one end of the cleaning cylinder 3 is provided on one side wall of the casing 2, and a discharge port 14 communicating with the other end of the cleaning cylinder 3 is provided on the other end of the casing 2.

[0030] In practical application, the medicinal materials enter the washing drum 3 directly through the feeding port 13 on one side wall of the machine casing, without disassembling the equipment or opening the machine casing 2. The feeding operation is simple and direct. After washing, the washing drum 3 continues to rotate. Under the action of centrifugal force and its own gravity, the washed medicinal materials inside move towards the discharge port 14 at the other end of the machine casing 2, and are finally discharged from the equipment through the discharge port 14, completing the unloading.

[0031] In this embodiment, the feeding port 13 and the discharge port 14 are located at both ends of the machine box 2 and are directly connected to the cleaning cylinder 3. Material can be added through the feeding port 13 while material is discharged through the discharge port 14, without stopping the machine and waiting, thus improving processing efficiency.

[0032] The above embodiments also include: Multiple guide plates 16 are arranged in a spiral shape on the inner wall of the cleaning cylinder 3.

[0033] In practical applications, when the washing drum 3 rotates, the spirally arranged guide plate 16 rotates synchronously with the washing drum 3. On the one hand, it drives the medicinal materials to move slowly along the spiral direction, avoiding local accumulation of medicinal materials and ensuring that each batch of medicinal materials can evenly contact the brush assembly 4. On the other hand, the guide plate 16 pushes the medicinal materials to tumble more forcefully, increasing the frequency of contact between the medicinal materials and the brush and spray water flow. After washing, the spiral structure of the guide plate 16 forms a pushing force, continuously conveying the washed medicinal materials towards the discharge port 14 during the rotation of the washing drum 3. Combined with centrifugal force and gravity, it achieves rapid and thorough discharge, avoiding medicinal material residue.

[0034] In this embodiment, the spiral guidance of the guide plate 16 causes the medicinal materials to undergo a combined rotational and axial movement within the cleaning cylinder 3, preventing the materials from remaining stationary or clustering in certain areas. This ensures that all materials undergo sufficient friction and spraying, avoiding cleaning dead zones. The directional pushing function of the guide plate 16 allows for seamless integration of feeding, cleaning, and discharging. After entering through the feeding port 13, the medicinal materials gradually move along the spiral trajectory to the discharge port 14, requiring no manual intervention throughout the process and enabling uninterrupted batch processing. Compared to discharging solely by gravity and centrifugal force, the active pushing of the guide plate 16 accelerates the discharge speed and reduces the waiting time after cleaning, making it particularly suitable for highly viscous or irregularly shaped medicinal materials, preventing blockage of the discharge port. The guide plate 16 and the inner wall brush assembly 4 do not interfere with each other. The spiral layout does not affect the friction between the brush and the medicinal materials and can also push the medicinal materials to tumble, making it easier for the brush to clean impurities on different sides of the medicinal materials, further improving cleanliness.

[0035] The above embodiments also include: The controller 15 is fixedly mounted on the chassis 2 and is electrically connected to the drive device 6.

[0036] In practical applications, operators can set or adjust the output power of motor 601 through controller 15, thereby changing the rotation speed of cleaning drum 3; according to the type of medicinal materials and the degree of contamination, the cleaning time is preset, and controller 15 automatically times the time and stops the drive device 6 after completion, realizing timed cleaning and avoiding over-cleaning or under-cleaning; the start and stop of drive device 6 can be directly controlled by the button of controller 15, replacing the traditional mechanical switch, making operation more convenient and easy to integrate into automated production lines.

[0037] In this embodiment, different medicinal materials have different requirements for cleaning intensity and time. The controller 15 can match personalized cleaning parameters by adjusting the rotation speed and duration, which can ensure cleanliness and protect the quality of medicinal materials to the greatest extent. There is no need to manually adjust the mechanical transmission components. The parameters can be set through the interface of the controller 15, which reduces the skill requirements of the operator and is especially suitable for small and medium-sized processing scenarios.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
