Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine pulverizing equipment, and in particular to a pulverizing equipment for Dendrobium officinale raw materials. Background Technology

[0002] Dendrobium officinale is a perennial herbaceous plant belonging to the genus Dendrobium in the family Orchidaceae. It thrives in warm, humid, and semi-shaded environments. It is distributed in Fujian, Zhejiang, Yunnan, and other regions. Dendrobium officinale has various health benefits, including nourishing the stomach and promoting the production of body fluids, nourishing yin and clearing heat, lowering blood sugar and lipids, anti-tumor effects, and anti-aging properties. Generally, Dendrobium officinale needs to be pulverized before use. Depending on the requirements, fresh Dendrobium officinale can be crushed into a pulp, or the dehydrated Dendrobium officinale can be crushed into a dry powder.

[0003] Chinese Patent Publication No. CN118437470A discloses a high-safety Dendrobium officinale pulverizing device, relating to the technical field of traditional Chinese medicine pulverizing equipment.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the device cools down by spraying water. Since water cannot be added when crushing dried Dendrobium, otherwise it cannot form powder, the device crushes fresh Dendrobium into a slurry.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] Reference Figure 1-7 As shown, the present invention provides a technical solution: a Dendrobium officinale raw material crushing device, comprising an outer shell 1; a crushing cylinder 2 is fixedly connected to the inner side of the outer shell 1 via a bracket; an upper cylinder cover 3 is fitted onto the top of the inner side of the crushing cylinder 2; a crushing assembly 4 is provided in the inner cavity of the crushing cylinder 2; a connecting pipe 5 is sleeved on the middle of the top of the upper cylinder cover 3; the lower end of the connecting pipe 5 extends into the inner cavity of the crushing cylinder 2; a plurality of circumferentially arranged air nozzles 6 are fixedly connected to the lower end of the connecting pipe 5; the air outlets of the air nozzles 6 are downwardly oriented; a high-pressure air pump 7 is fixedly connected to the top surface of the upper cylinder cover 3 near the edge; the air outlet of the high-pressure air pump 7 is fixedly connected to the middle of the connecting pipe 5; the air inlet of the high-pressure air pump 7 is fixedly connected to the side wall of the outer shell 1 and extends to the outside. The lower end of the side wall of the crushing cylinder 2 is provided with several first exhaust ports 8 arranged in a circle. The top of the upper cylinder cover 3 is provided with second exhaust ports 9 arranged in a symmetrical manner. The lower end of the outer wall side surface of the crushing cylinder 2 is movably sleeved with a barrier ring 10. The top of the barrier ring 10 is symmetrically fixedly connected with a connecting plate 11. One end of each of the two connecting plates 11 is fixedly connected with a sealing block 12. Both sealing blocks 12 are located on the upper side of the upper cylinder cover 3. The lower ends of the two sealing blocks 12 are respectively inserted into the top of the adjacent second exhaust ports 9. Both sides of the inner wall of the outer shell 1 are fixedly connected with support blocks 13. The top surface of each of the two support blocks 13 is fixedly connected with a first electric push rod 14. The output end of the first electric push rod 14 is fixedly connected to the bottom surface of the barrier ring 10.

[0022] In order to crush the Dendrobium inside the crushing cylinder 2, the crushing assembly 4 includes a first motor 41. The output shaft of the first motor 41 is fixedly connected to a connecting shaft 42. The connecting shaft 42 is sleeved in the connecting pipe 5 and its lower end extends into the inner cavity of the crushing cylinder 2. Several crushing blades 43 are fixedly connected to the lower end of the side wall of the connecting shaft 42.

[0023] To ensure a more uniform airflow from the nozzle 6, a driven gear 15 is fixedly fitted onto the upper end of the outer wall of the connecting pipe 5. A second motor 16 is fixedly connected to the top surface of the outer wall of the upper cylinder cover 3, near the edge. The shaft of the second motor 16 is fixedly connected to a driving gear 17, which meshes with the driven gear 15. By rotating the nozzle 6, the high-pressure airflow can more comprehensively cover the Dendrobium.

[0024] To allow the dendrobium to be discharged from the bottom of the grinding cylinder 2, a lower cylinder cover 18 is movably fitted onto the bottom of the inner side of the grinding cylinder 2. The lower end face bearing of the connecting shaft 42 is connected to the middle of the top surface of the lower cylinder cover 18. Sealing strips are fixedly fitted onto the side surfaces of both the upper cylinder cover 3 and the lower cylinder cover 18. When it is necessary to discharge the dendrobium from the grinding cylinder 2, the lower cylinder cover 18 can be moved out of the grinding cylinder 2, allowing the dendrobium to be discharged from the bottom of the grinding cylinder 2.

[0025] To ensure more thorough removal of Dendrobium from the grinding cylinder 2, a second electric actuator 19 is fixedly connected to the top surface of the inner wall of the outer casing 1. A mounting plate 20 is fixedly connected to the output end of the second electric actuator 19, and a first motor 41 is fixedly connected to the bottom surface of the mounting plate 20. When it is necessary to remove Dendrobium from the grinding cylinder 2, the upper cylinder cover 3 can be lowered by pushing the second electric actuator 19. As the upper cylinder cover 3 lowers, its side wall scrapes against the inner wall of the grinding cylinder 2, removing the Dendrobium adhering to the inner wall, thus ensuring more thorough removal and reducing waste.

[0026] To prevent smaller pieces of Dendrobium from being discharged from the first vent 8 or the second vent 9 after crushing, a first filter screen 21 is fixedly connected inside the first vent 8, and a second filter screen 22 is fixedly connected inside the second vent 9. The first filter screen 21 and the second filter screen 22 can respectively block the first vent 8 and the second vent 9, preventing larger pieces of Dendrobium from being discharged after crushing.

[0027] To collect the Dendrobium discharged from the crushing cylinder 2 from the bottom, an opening is provided in the middle of the front side of the outer shell 1, and a door 23 is connected to the front hinge of the outer shell 1. A collection port 24 is provided at the bottom of the front side of the outer shell 1. The collection container can be placed at the bottom of the inner cavity of the outer shell 1 through the collection port 24, so that the container is placed at the bottom of the crushing cylinder 2, thereby collecting the discharged Dendrobium.

[0028] To ensure that the blocking ring 10 can block the first exhaust port 8 when it rises, the inner side of the blocking ring 10 is in contact with the side surface of the outer wall of the crushing cylinder 2, and the blocking ring 10 is located below the first exhaust port 8. When the sealing block 12 rises and is pulled out from the second exhaust port 9, the blocking ring 10 also rises to block the first exhaust port 8.

[0029] To facilitate the operation of the electrical equipment on the control device, a controller 25 is fixedly connected to the housing 1. The controller 25 is electrically connected to the first electric push rod 14, the second electric push rod 19, the first motor 41, and the second motor 16.

[0030] To allow the air discharged from the high-pressure air pump 7 to be delivered to the nozzle 6 through the connecting pipe 5, a connecting cavity 26 is provided inside the connecting pipe 5. The air inlet end of the nozzle 6 extends into the connecting cavity 26, and the air outlet end of the high-pressure air pump 7 also extends into the connecting cavity 26. High-pressure air enters the connecting cavity 26 and is then discharged into the nozzle 6 through the connecting cavity 26.

[0031] Working Principle: Users can control the electrical equipment on the device using the controller 25. The specific operation process is as follows: First, the second electric actuator 19 moves the crushing component 4 upward, allowing the upper cylinder cover 3 to be pulled out of the crushing cylinder 2. Next, the operator places the Dendrobium into the crushing cylinder 2. Subsequently, the second electric actuator 19 moves again, pushing the upper cylinder cover 3 downward, so that it is reinserted into the top of the inner cavity of the crushing cylinder 2. Then, the first motor 41 is started, driving the connected shaft 42 to rotate. The connected shaft 42 further drives the crushing blade 43 to rotate, thereby crushing the Dendrobium in the crushing cylinder 2. During the crushing process, the high-pressure air pump 7 delivers high-pressure air into the connecting cavity 26 of the connecting pipe 5. The high-pressure air in the connecting cavity 26 enters the nozzle 6 and is sprayed downward through the outlet end of the nozzle 6. This downward-flowing high-pressure air is finally discharged through the first exhaust port 8. The downward-flowing high-pressure air compresses the Dendrobium inside the pulverizing cylinder 2. Simultaneously, the second motor 16 drives the drive gear 17 to rotate, which in turn drives the driven gear 15, causing the connecting pipe 5 to rotate, which in turn drives the jet nozzle 6. This allows the downward-flowing high-pressure air to more comprehensively cover the Dendrobium inside the pulverizing cylinder 2. After being compressed, the Dendrobium's fluidity decreases, increasing the contact probability between the Dendrobium and the pulverizing blades 43 per unit volume. The shearing and impact forces applied by the pulverizing blades 43 can act more directly on individual Dendrobium particles, reducing energy loss and enabling the pulverizing blades 43 to more effectively crush the Dendrobium, thus improving the pulverizing effect and efficiency. Furthermore, the first electric push rod 14 can periodically push the blocking ring 10 upwards. When the blocking ring 10 moves upwards, it blocks the first exhaust port 8, and simultaneously, through the connecting plate 11, it causes the sealing block 12 to rise, exposing the second exhaust port 9. At this point, because the first exhaust port 8 is blocked, the upward-flowing high-pressure air cannot escape from below and will move upward after impacting the top surface of the lower cylinder cover 18. This upward flow of high-pressure air causes the Dendrobium to tumble, increasing the number of contacts between the pulverizing blade 43 and the Dendrobium material per unit time. This tumbling action breaks up the stratification of the material through turbulence, reducing the pulverizing dead zone and further improving the cutting effect and efficiency of the Dendrobium. Furthermore, the flow of high-pressure air within the pulverizing cylinder 2 cools the cylinder 2 and its internal components, thus preventing excessive temperature from affecting the quality of the Dendrobium.

[0032] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
