Description

Technical Field

[0001] This invention relates to the field of drug grinding technology, and in particular to a device for crushing drugs that combines traditional Chinese and Western medicine. Background Technology

[0002] In the medical field, medicines often require grinding before use, especially in the application of traditional Chinese medicine and the research and analysis of Western medicine components. The traditional method involves manually crushing the medicine and then grinding it manually in a grinding device. During this process, workers cannot guarantee even pressure from the device. Furthermore, the process requires transferring the medicine between two devices, increasing labor intensity, reducing processing efficiency, and increasing the risk of drug contamination, thus affecting the drug's efficacy.

[0003] To address the aforementioned technical problems, a patent for a drug crushing and grinding device has been disclosed by those skilled in the art, with publication number CN211613003U. This invention utilizes a rocker arm to drive an incomplete gear. When the incomplete gear meshes with a first rack, the first rack moves to the left, further driving a moving block to the left. Due to the protrusion at the bottom of the moving block, the column moves downward, causing the grinding pestle to move downward, thus crushing and grinding the drug inside the pestle. When the incomplete gear rotates and meshes with a second rack, the second rack moves to the right, further driving the moving block to the right. The spring returns to its original deformation, causing the grinding pestle to move upward, further driving the column upward. Continuing to rotate the rocker arm causes the grinding pestle to move repeatedly up and down, ensuring the drug inside the pestle is thoroughly ground. Finally, the user can collect the ground drug by rotating a bolt. Compared with existing technologies, this device provides uniform force, uniform grinding speed, and good grinding effect.

[0004] However, the aforementioned invention requires constant operation and adjustment by staff during practical application, making the entire process cumbersome and failing to effectively reduce the workload of workers. Furthermore, the invention's structural design is complex, employing numerous driving and connecting components, making it prone to malfunctions and resulting in high production and maintenance costs. Therefore, developing a device capable of automatically and effectively crushing and grinding drugs is of great significance for improving medical efficiency and drug efficacy. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by designing a drug crushing device that combines traditional Chinese and Western medicine.

[0006] The technical solution of the present invention to achieve the above objectives is as follows: a drug crushing device combining traditional Chinese and Western medicine, comprising a base, a support mounted on the upper surface of the base, a crushing box fixedly mounted on the support, a feeding port and a discharging port on the side surface of the crushing box, an electrically controlled valve installed at the discharging port, a material box placed on the base, the material box being able to receive the crushed drugs discharged from the discharging port, a motor mounted on the upper surface of the crushing box, and a crushing chamber and a grinding chamber provided inside the crushing box, the crushing chamber being located in the upper part of the crushing box, the grinding chamber being located in the lower part of the crushing box, and the upper opening of the grinding chamber being connected to the bottom of the crushing chamber. The surface is connected, and the mortar and pestle chamber is equipped with a mortar and pestle unit and a grinding unit. The upper ends of the mortar and pestle unit and the grinding unit both pass through the top surface of the mortar and pestle chamber and extend to the top of the mortar and pestle box body. The lower end of the mortar and pestle unit is close to the bottom surface of the mortar and pestle chamber, and the lower end of the grinding unit is inserted into the grinding chamber. The upper end of the grinding unit is connected to the rotating shaft of the motor and rotates under the drive of the motor. During the rotation, the grinding unit can periodically contact the mortar and pestle unit and push the mortar and pestle unit to rise. When the mortar and pestle unit lose contact with the grinding unit, the mortar and pestle unit can fall and crush under the action of gravity.

[0007] The grinding chamber is funnel-shaped, and its bottom surface is connected to the discharge port. A filter screen is installed at the upper opening of the grinding chamber. The filter screen can intercept uncrushed drugs. The grinding unit passes through the filter screen, and the crushing unit is located on one side of the grinding unit. The crushing unit can impact the drugs to be crushed on the bottom surface of the crushing chamber during its descent.

[0008] The grinding unit includes a grinding roller and a bearing housing. The grinding roller passes through the filter screen. The central shaft at the upper end of the grinding roller is connected to the rotating shaft of the motor via a coupling. The bearing housing is embedded in the bottom surface of the grinding chamber. The central shaft at the lower end of the grinding roller is inserted into the bearing housing. Several guide rails are provided on the side surface of the grinding roller. The guide rails are all located above the filter screen and are parallel to each other. The guide rails are distributed at equal intervals around the center line of the grinding roller on the side surface of the grinding roller. The guide rails are inclined guide rails with one end close to the filter screen and the other end close to the top surface of the grinding chamber.

[0009] A connecting rope is provided on the side surface of the grinding roller. One end of the connecting rope is fixedly connected to the side surface of the grinding roller, and the other end of the connecting rope is connected to a ball bearing. When the grinding roller rotates, the connecting rope can pull the ball bearing to roll on the filter screen.

[0010] The guide rail is a straight track or an arc track. When the grinding roller rotates under the drive of the motor, one end of the guide rail first contacts the mortar unit and pushes the mortar unit to rise along the guide rail. After the mortar unit moves to the other end of the guide rail and disengages from the other end of the guide rail, it begins to fall. After falling, the mortar unit can hit the medicine on the bottom surface of the mortar chamber to complete the mortaring action. Several guide rails can continuously push the mortar unit to form a reciprocating mortaring action.

[0011] The mortar unit includes a lifting body and a fixed shaft. A hammer is mounted on the lower surface of the lifting body. One end of the fixed shaft is fixedly connected to the side surface of the lifting body. The other end of the fixed shaft is close to the side surface of the grinding roller and inserted between two adjacent guide rails. A roller is mounted on the other end of the fixed shaft. When the grinding roller rotates, the edge of the roller can contact the guide rail and roll along the guide rail.

[0012] The length direction of the fixed shaft is perpendicular to the side surface of the lifting body, and the lower surface of the hammer head is provided with several protrusions. The hammer head is detachably connected to the lower surface of the lifting body.

[0013] A baffle is fixedly installed on the upper end face of the lifting body. Several counterweights can be installed on the upper surface of the baffle. The number of counterweights can be adjusted by disassembly and installation.

[0014] One end of the guide rail is positioned lower than the roller. When the grinding roller rotates, one end of the guide rail can extend below the roller and push the roller upwards along the guide rail.

[0015] The side surface of the mortar and pestle box is provided with two observation windows, one for observing the mortar and pestle chamber and the other for observing the grinding chamber.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes the rotation of the grinding roller and the periodic lifting and lowering of the crushing structure by the guide rail on the side surface of the grinding roller to achieve the linkage effect of crushing and grinding drugs. This effectively simplifies the structural complexity of the device, reduces the production and maintenance costs of the device, and can better meet the needs of enterprises. 2. This invention utilizes a motor-driven grinding unit and a crushing unit in a linked manner to achieve the dual functions of grinding and crushing drugs. The entire processing process requires no manual transfer, adjustment, or operation, effectively reducing the labor intensity of workers, improving processing efficiency, avoiding drug contamination, and ensuring processing quality. 3. The present invention has a filter screen on the grinding chamber to separate the crushed medicine, which avoids the crushing action from pushing the medicine directly into the grinding chamber, thus ensuring the effect of medicine grinding.

A material box 6 is placed on the base 1, the material box 6 being a sealed box, the position of the material box 6 matching the position of the discharging port 5, and a flexible hose connected to the discharging port 5. The crushed and ground drugs fall directly into the material box 6 through the discharging port 5 and the flexible hose. A motor 7 is installed on the upper surface of the crushing box 3, the shaft of the motor 7 pointing vertically downwards towards the upper surface of the crushing box 3. The box body 3 is provided with a mortar chamber 8 and a grinding chamber 9. The mortar chamber 8 is located at the upper part of the mortar box body 3, and the grinding chamber 9 is located at the lower part of the mortar box body 3. The upper opening of the grinding chamber 9 is connected to the bottom surface of the mortar chamber 8. The mortar chamber 8 is provided with a mortar unit and a grinding unit. The upper ends of the mortar unit and the grinding unit pass through the top surface of the mortar chamber 8 and extend to the top of the mortar box body 3. The lower end of the mortar unit is close to the bottom surface of the mortar chamber 8, and the lower end of the grinding unit is inserted into the grinding chamber 9. The upper end of the grinding unit is connected to the rotating shaft of the motor 7 and rotates under the drive of the motor 7. During the rotation, the grinding unit can periodically contact the mortar unit and push the mortar unit to rise. When the mortar unit and the grinding unit are separated, the mortar unit can fall and crush under the action of gravity.

[0019] It should be noted that the bottom surface of the grinding chamber 8 is inclined, and the bottom surface of the grinding chamber 8 is inclined to the upper opening of the grinding chamber 9. The grinding chamber 9 is funnel-shaped, and the bottom surface of the grinding chamber 9 is connected to the discharge port 5. A filter screen is installed at the upper opening of the grinding chamber 9. The filter screen can intercept uncrushed drugs. The grinding unit passes through the filter screen, and the grinding unit is located on one side of the grinding unit. During the descent, the grinding unit can impact the drugs to be crushed on the bottom surface of the grinding chamber 8.

[0020] In embodiment 1, the grinding unit includes a grinding roller 10 and a bearing seat 11. The grinding roller 10 passes through the filter screen. The central shaft at the upper end of the grinding roller 10 extends out of the upper surface of the mortar box 3. The central shaft at the upper end of the grinding roller 10 is connected to the rotating shaft of the motor 7 through a coupling. The bearing seat 11 is embedded in the bottom surface of the grinding cavity 9. The central shaft at the lower end of the grinding roller 10 is inserted into the bearing seat 11. The grinding roller 10 can rotate under the drive of the motor 7. The diameter of the grinding roller 10 matches the diameter of the bottom surface of the grinding cavity 9. The lower surface of the grinding roller 10 is close to the bottom surface of the grinding cavity 9. Several guide rails 12 are provided on the side surface of the grinding roller 10. The several guide rails 12 are all located above the filter screen. The several guide rails 12 are all long strip tracks. The several guide rails 12 are parallel to each other. The several guide rails 12 are distributed at equal intervals around the center line of the grinding roller 10 on the side surface of the grinding roller 10. The guide rail 12 is an inclined guide rail 12 with one end close to the filter screen and the other end close to the top surface of the mortar box 8.

[0021] The grinding roller 10 has a connecting rope on its side surface. One end of the connecting rope is fixedly connected to the side surface of the grinding roller 10, and the other end of the connecting rope is connected to the ball bearing 13. When the grinding roller 10 rotates, the connecting rope can pull the ball bearing 13 to roll on the filter screen. The ball bearing 13 continuously vibrates the filter screen during the rolling process and prevents the drug from clogging the filter screen.

[0022] It should be noted that the guide rail 12 is a straight track or an arc track. When the grinding roller 10 rotates under the drive of the motor 7, one end of the guide rail 12 first contacts the mortar unit and moves the mortar unit to rise along the guide rail 12. After the mortar unit moves to the other end of the guide rail 12 and disengages from the other end of the guide rail 12, it begins to fall. After falling, the mortar unit can hit the medicine on the bottom surface of the mortar chamber 8 to complete the mortaring action. Several guide rails 12 can continuously move the mortar unit to form a reciprocating mortaring action.

[0023] In Embodiment 1, the mortar unit includes a lifting body 14 and a fixed shaft 15. A hammer 16 is mounted on the lower surface of the lifting body 14. One end of the fixed shaft 15 is fixedly connected to the side surface of the lifting body 14. The other end of the fixed shaft 15 is close to the side surface of the grinding roller 10 and inserted between two adjacent guide rails 12. A roller 17 is mounted on the other end of the fixed shaft 15. The roller 17 can rotate around the other end of the fixed shaft 15. When the grinding roller 10 rotates, the edge of the roller 17 can contact the guide rail 12 and roll along the guide rail 12.

[0024] The lifting body 14 is prismatic in shape. The length direction of the fixed shaft 15 is perpendicular to the side surface of the lifting body 14. One end of the fixed shaft 15 is fixedly connected to the side surface of the lifting body 14 by welding. The hammer head 16 is rectangular or hemispherical in shape. Several protrusions are provided on the lower surface of the hammer head 16. The hammer head 16 is detachably connected to the lower surface of the lifting body 14. A baffle 18 is fixedly installed on the upper end face of the lifting body 14. The size of the baffle 18 is larger than the size of the upper end face of the lifting body 14. The baffle 18 cannot enter the mortar chamber 8. Several counterweights can be detachably installed on the upper surface of the baffle 18. The number of counterweights can be adjusted by disassembly and installation.

[0025] It should be noted that the diameter of the roller 17 is matched with the distance between the two adjacent guide rails 12. One end of the guide rail 12 is lower than the position of the roller 17. When the grinding roller 10 rotates, one end of the guide rail 12 can extend to the bottom of the roller 17 and push the roller 17 to rise along the guide rail 12. Two observation windows are provided on the side surface of the mortar box 3. One observation window is used to observe the mortar chamber 8, and the other observation window is used to observe the grinding chamber 9.

[0026] The electronic devices used in this technical solution are all existing products, and the technical solution of this application does not have any special requirements or changes to the structure of the above-mentioned electronic devices; During the implementation of this technical solution, those skilled in the art need to connect all electrical components and their compatible power supplies via wires, and should select a suitable controller according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle of this technical solution and the sequential operation order of each electrical component; the detailed connection methods are well-known in the art. This technical solution mainly introduces the working principle and process, and will not further explain electrical control.

[0027] In Example 1, during the specific implementation process, the staff put Chinese medicinal materials or Western medicines into the mortar and pestle chamber 8 through the inlet 4. At this time, the Chinese medicinal materials or Western medicines fall into the mortar and pestle chamber 8 and the filter screen. Then, the motor 7 is started, and the shaft of the motor 7 drives the grinding roller 10 to rotate. During the rotation of the grinding roller 10, one end of the guide rail 12 can extend under the roller 17 and push the roller 17 to rise along the guide rail 12. The lifting body 14 rises with the roller 17 and the fixed shaft 15. When the roller 17 reaches the other end of the guide rail 12 and disengages from the other end of the guide rail 12, the lifting body 14 begins to fall under the action of gravity. The hammer 16 at the lower end of the lifting body 14 can hit the medicine on the bottom surface of the mortar and pestle chamber 8 to complete the mortar and pestle action, while the roller 17 falls back to its original position until it is pushed up by the next guide rail 12. As the grinding roller 10 rotates, several guide rails 12 can continuously push the roller 17 and cause the lifting body 14 and the hammer 16 to form a reciprocating mortar and pestle action.

[0028] The crushed medicine falls into the grinding chamber 9 after passing through a filter screen. Inside the grinding chamber 9, rotating grinding rollers 10 grind the crushed medicine from coarse to fine. After falling to the bottom of the grinding chamber 9, the medicine is ground and pushed by the grinding rollers 10 into the discharge port 5, and then falls into the material tank 6. When the material tank 6 is full, the operator disconnects the hose from the material tank 6 and replaces it with a new material tank 6 to receive the medicine. During the replacement process, the operator needs to close the electrically controlled valve and disinfect the discharge port 5.

[0029] The entire working environment of the drug crushing and grinding device is strictly disinfected. The drug crushing and grinding device can also be equipped with various sensors, such as weight sensors, humidity sensors and temperature sensors, to monitor the properties and state of the drug in the crushing chamber 8 and grinding chamber 9, and ensure the freshness and activity of the drug during the crushing and grinding process.
