Description

Technical Field

[0001] The present invention relates to the technical field of medicinal material grinding, in particular to a medicinal material grinding device for traditional Chinese medicine nursing. Background Art

[0002] Grinding medicinal herbs is a critical and fundamental operation, the results of which directly impact the effectiveness of subsequent Traditional Chinese Medicine treatment and care. With the widespread application and development of Traditional Chinese Medicine, higher requirements are being placed on the performance and efficiency of medicinal herb grinding equipment.

[0003] In the prior art, patent publication number CN114887726A proposes a medicinal material grinding device for traditional Chinese medicine nursing. This device solves the problems of low efficiency and high labor intensity of traditional manual grinding to a certain extent. However, in actual application, it still exposes many defects.

[0004] The structural design of the device has deficiencies, and the layout and movement of its grinding components are not reasonable. The coordination between the grinding components is not smooth enough, and it is difficult to achieve comprehensive and uniform grinding when grinding Chinese medicinal materials of various textures and shapes. For example, it is impossible to achieve the ideal grinding effect for both hard rhizome medicinal materials and thin and fragile flower and leaf medicinal materials at the same time. Some medicinal materials tend to accumulate in corners or specific parts of the device, resulting in insufficient grinding, causing waste of medicinal materials and affecting the quality uniformity of the final product.

[0005] In terms of power transmission and control, the device lacks a precise and effective regulation mechanism. The motor speed is fixed or has a limited adjustment range, making it impossible to flexibly adjust to the characteristics of different medicinal materials. For some medicinal materials that require gentle grinding to retain their active ingredients, excessively high speeds may cause the ingredients to volatilize or be destroyed. For tougher medicinal materials, insufficient speeds make efficient grinding difficult. Significant energy loss occurs during power transmission, which not only reduces energy efficiency but can also cause the device to generate significant heat during operation, affecting its stability and service life.

[0006] The cleaning and maintenance of this device is also relatively inconvenient. The internal structure is complex and there are many hard-to-reach dead corners. After each grinding work is completed, the residual medicinal powder is very likely to adhere to the inside of the device, and it takes a lot of time and energy to clean it. If the cleaning is not thorough, the residual medicinal powder may become moldy and cross-contaminated, thereby affecting the quality and safety of the next grinding of medicinal materials. At the same time, it will also accelerate the corrosion and damage of the internal parts of the device. Therefore, this device provides a medicinal material grinding device for traditional Chinese medicine nursing. Summary of the Invention

[0018] The at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0019] First, this device integrates herbal material crushing, grinding, shelling, and temperature control functions in one device, meeting the diverse needs of TCM care for a wide range of herbs and processing requirements. Whether it's hard fruit or seed herbs that require shelling, or flowers, leaves, or animal herbs that require fine grinding and temperature control, all can be processed in one place, reducing the tedious operations and space consumption associated with switching between multiple devices.

[0020] Secondly, as the self-rotating grinding balls in this device rotate, the centrifugal force generated by their rotation can disperse larger medicinal materials to the sides, causing them to contact the inclined grinding walls of the surrounding grinding chamber and be further ground by the surrounding grinding rollers. This design cleverly achieves differentiated treatment for medicinal materials of different sizes, ensuring both fine grinding of small-particle medicinal materials and fully utilizing the surrounding grinding rollers' efficient grinding effect on large-volume medicinal materials. This prevents large-particle medicinal materials from remaining due to insufficient grinding, improving the integrity and utilization rate of medicinal material grinding. The combination of the self-rotating grinding balls and the surrounding grinding rollers forms a dual grinding system for bottom grinding and sidewall grinding. The two complement each other, covering all areas within the surrounding grinding chamber, ensuring that the medicinal materials are ground in all directions and without blind spots. This effectively reduces blind spots in medicinal material grinding, allows for the full crushing of hard medicinal materials, maximizes the release of active ingredients, improves the grinding effect and medicinal material quality, and achieves targeted treatment of large and small medicinal materials and the synergistic effect of the dual grinding structure.

[0021] Thirdly, the current grinding devices with complex internal structures have many hard-to-reach dead corners. After each grinding operation, the residual medicinal powder is very likely to adhere to the inside of the device, and cleaning it requires a lot of time and effort. If the cleaning is not thorough, the residual medicinal powder may become moldy, cross-contaminated, etc., which will affect the quality and safety of the next grinding of medicinal materials, and will also accelerate the corrosion and damage of the internal parts of the device. This device is easy to maintain. Through the convenient cleaning and maintenance design, it not only saves manpower and time costs, but more importantly, it ensures the cleanliness and hygiene of the inside of the device, effectively avoiding quality problems caused by residual medicinal material contamination, while extending the service life of the equipment and reducing the frequency of equipment upgrades. In the long run, it saves users a lot of money. The inner ring chamber of this device is removable, the inner ring grinding head is removable, and the surrounding grinding chamber is removable, which greatly facilitates cleaning operations.

[0022] Fourthly, this device can efficiently break the shell and accurately separate the nuts: the unique inner ring chamber and impact structure can quickly break the hard shell and accurately separate the kernel and the shell. The impact motor drives the inner ring grinding head for directional impact, and cooperates with the drive motor to adjust the position. It can efficiently break the shells of medicinal materials such as almonds and peach kernels, avoid damage to the kernels by traditional crushing methods, and improve the complete retention rate of effective ingredients.

[0023] Fifth, animal medicinal materials such as keratin and crustaceans, representative medicinal materials: such as tortoise shell, turtle shell, deer antler, etc., have a hard texture and dense structure. They are suitable for grinding. They are first heated to make their texture brittle, and then ground into fine powder using special grinding equipment at a higher speed and greater pressure. For example, tortoise shell is easier to decoct the effective ingredients after heating and grinding. Therefore, in mineral medicinal materials: such as gypsum, magnet, natural copper, etc., these medicinal materials have a hard texture and stable chemical properties, and high temperature is not easy to cause changes in composition. Through high-temperature grinding, its texture can become loose and ground into extremely fine powder, which is conducive to human absorption and enhances the efficacy. For example, gypsum can better play its role in heat-clearing and fire-purging prescriptions after high-temperature grinding. As for some seed-based medicinal materials: such as cassia seeds and radish seeds, high-temperature frying and grinding can change their internal structure, destroy the enzymes in the seeds, and prevent the ingredients from being enzymatically hydrolyzed during storage, while enhancing the efficacy. The fried cassia seeds are ground into powder, which has better effects on clearing the liver and improving eyesight, and can also reduce its side effect of laxative. When the Chinese medicine in this device needs to be ground at high temperature, the medicine is ground and placed in the inner ring chamber for grinding. During the grinding process, the temperature of the inner ring grinding head is controlled by the temperature heating and cooling device to meet the required medicinal material grinding requirements.

[0054] Common Chinese medicine nursing materials are generally divided into five categories: rhizome materials, fruit and seed materials, flower and leaf materials, mineral materials and animal materials. Rhizome materials can be further divided into hard and loose materials. Representative materials of hard texture include Panax notoginseng, Polygonum cuspidatum, Rhubarb, etc. These materials have dense and hard texture and high fiber content, making them difficult to grind directly. Suitable grinding methods include: pre-treatment first, cutting them into thin slices or small pieces, and grinding them at a higher speed and higher pressure using a grinding device with a carbide grinding head. During the grinding process, it can be carried out in stages. First, coarse grinding is carried out to break the medicinal materials into smaller particles, and then fine grinding is carried out until the required powder fineness is achieved. Taking Panax notoginseng as an example, after such grinding, its dense structure can be effectively broken and the dissolution rate of the effective ingredients can be improved. When the device is used to grind hard medicinal materials, the medicinal materials can first be placed into the crushing chamber 33 through the medicinal material discharge port 36 on the crushing chamber 33. At this time, the crushing motor 32 is driven to drive the crushing blades on the output end of the crushing motor 32 to rotate inside the crushing chamber 33, thereby crushing the inside of the crushing chamber 33. The medicinal materials in the crushing chamber 33 are cut into thin slices or small pieces. After the medicinal materials in the crushing chamber 33 are crushed and cut into thin slices or small pieces, the control valve at the discharge port at the lower end of the crushing chamber 33 is started to open the lower end of the crushing chamber 33, so that the crushing chamber 33 and the discharge channel 35 are in a connected state, allowing the cut medicinal materials to flow from the discharge channel 35 into the surrounding grinding chamber 215 for grinding. At this time, the driving motor 513 drives the transmission disc 528 to perform a peripheral circular motion along the attached wall with the transmission groove 515 as the axis, and the rotation mode of the slave shaft 524 is the same as that of the transmission disc 528. The rotation of the slave shaft 524 will drive the orbiting self-rotating block 211 to orbit inside the orbiting grinding chamber 215. The orbiting motion of the orbiting self-rotating block 211 will drive the orbiting self-rotating rod to orbit, and finally drive the orbiting self-rotating ball to grind at the bottom of the orbiting grinding chamber 215, thereby grinding the cut medicinal materials entering the orbiting grinding chamber 215. At the same time, the orbiting motion of the orbiting self-rotating block 211 will also drive the orbiting self-rotating gear 212 to orbit. Since the orbiting self-rotating gear 212 is meshed with a plurality of teeth arranged around the inner side of the driving chamber 512, The orbiting self-rotating gear 212 is fixedly connected to the orbiting self-rotating rod 213, and the orbiting self-rotating rod 213 is rotationally connected to the orbiting self-rotating block 211. The orbiting motion of the orbiting self-rotating gear 212 will generate a self-rotating motion, so that the orbiting self-rotating rod 213 will rotate while orbiting the inner side of the driving chamber 512. Finally, the orbiting self-rotating grinding ball 214 will rotate while orbiting the inner side of the driving chamber 512. In this way, the medicinal materials are ground, and the orbiting self-rotating block 211 will also drive the orbiting grinding rod 221 to orbit while orbiting.The orbiting motion of the orbiting grinding rod 221 will eventually drive the orbiting grinding roller 223 to orbit around the inclined grinding wall 216 inside the orbiting grinding chamber 215, thereby grinding the medicinal materials cut on the inclined grinding wall 216 inside the orbiting grinding chamber 215. The orbiting and self-rotating grinding balls 214 can also rotate at the same time, so that the medicinal materials can be ground more finely. Due to the different volumes of medicinal materials, the orbiting and self-rotating grinding balls 214 can also rotate at the same time, so that the larger medicinal materials will be dispersed and dispersed over a larger distance due to the self-rotating side ends of the orbiting and self-rotating grinding balls 214. The larger medicinal materials are dispersed to the inclined grinding wall 216 for grinding. The larger medicinal materials can be ground with maximum efficiency by the orbiting grinding roller 223. The complementary grinding of the orbiting grinding roller 223 and the orbiting and self-rotating grinding balls 214 can fully grind the medicinal materials, greatly improving the fineness of the medicinal materials grinding, making the powder particle size more uniform, and helping to improve the dissolution rate of the effective ingredients of the medicinal materials.

[0055] As the rotating grinding balls 214 of this device rotate, the centrifugal force generated by their rotation disperses larger medicinal materials toward the sides, allowing them to contact the inclined grinding walls 216 of the grinding chamber 215 and be further ground by the grinding rollers 223. This design cleverly achieves differentiated treatment for medicinal materials of varying sizes, ensuring fine grinding of small-particle medicinal materials while fully utilizing the efficient grinding effect of the grinding rollers 223 on larger-volume medicinal materials. This prevents the residue of large-particle medicinal materials due to incomplete grinding, thereby improving the completeness and utilization of the ground medicinal materials. The combination of the rotating grinding balls 214 and the grinding rollers 223 forms a dual grinding system: bottom grinding and sidewall grinding. These two systems complement each other, covering every area within the grinding chamber 215 and ensuring comprehensive, seamless grinding of medicinal materials within the chamber. This effectively reduces blind spots in the grinding process, allows for the full comminution of hard medicinal materials, maximizes the release of their active ingredients, and enhances both grinding efficiency and medicinal material quality. This achieves targeted treatment of large and small medicinal materials and the synergistic effect of the dual grinding structure.

[0056] Representative medicinal materials with loose geology: such as Atractylodes macrocephala, Chinese yam, licorice, etc., compared with hard rhizome medicinal materials, those with loose geology have relatively loose texture and low fiber content, and are suitable for grinding methods. Simple crushing of the medicinal materials can facilitate subsequent uniform grinding. By adjusting the speed of the drive motor 513, medium-speed grinding can be adopted. In order to avoid excessive grinding resulting in too fine powder, which affects subsequent use, the grinding time needs to be controlled. For example, when grinding Atractylodes macrocephala, medium-speed grinding can not only ensure grinding efficiency, but also keep the powder at a suitable particle size, which is convenient for preparation and use. This grinding method can be the same as the above-mentioned medicinal material grinding, or it can be directly ground. The medicinal materials are placed in the inner ring chamber 42, and the operation of the drive motor 513 drives the shaft 524 to rotate. The rotation of the shaft 524 drives the impact shell opening device 6 to rotate. The impact shell opening device 6 rotates and waits for the inner ring grinding head 41 to achieve grinding by circumferential motion inside the inner ring chamber 42, thereby directly grinding and taking out the medicinal materials with loose geology.

[0057] The mineral medicinal materials in this device are representative medicinal materials: such as gypsum, magnet, dragon bone, etc., which have hard texture, high density and stable chemical properties;

[0058] Suitable grinding method: High-intensity grinding equipment is required, and a long-time, high-speed, and high-pressure grinding method is adopted to grind it into extremely fine powder to facilitate human absorption. For example, gypsum can better exert its medicinal effect in prescriptions after being fully ground. The grinding method of mineral medicinal materials can be carried out in the same way as the grinding of root and rhizome medicinal materials with a hard texture.

[0059] Preferably, the impact shell opening device 6 includes an impact motor 61 and an impact rod 62, the impact motor 61 is arranged at the lower end of the slave shaft 524, the impact rod 62 is arranged on the output end of the impact motor 61, and the output end of the impact motor 61 is arranged downward, the inner ring medicinal material grinding device 4 includes an inner ring grinding head 41 and an inner ring chamber 42, the inner ring grinding head 41 is arranged at the lower end of the impact rod 62, the inner ring chamber 42 is threadedly connected to the inner side of the grinding chamber 215, the inner ring grinding head 41 is semicircular and blunt, the bottom of the inner ring chamber 42 is in an adapted state with the shape of the inner ring grinding head 41, and the transmission groove 515 and the inner ring chamber 42 are coaxially arranged;

[0060] At present, the grinding devices with complex internal structures have many hard-to-reach dead corners. After each grinding operation, the residual medicinal powder is very easy to adhere to the inside of the device, and cleaning requires a lot of time and energy. If the cleaning is not thorough, the residual medicinal powder may become moldy, cross-contaminated, etc., which will affect the quality and safety of the next grinding of medicinal materials, and will also accelerate the corrosion and damage of the internal parts of the device. The present device is easy to maintain. Through the convenient cleaning and maintenance design, it not only saves manpower and time costs, but more importantly, it ensures the cleanliness and hygiene of the inside of the device, effectively avoids quality problems caused by residual medicinal material contamination, and at the same time extends the service life of the equipment and reduces the frequency of equipment replacement. In the long run, it saves users a lot of money. The inner ring chamber 42 of the present device is removable, the inner ring grinding head 41 is removable, and the surrounding grinding chamber 215 is removable, which greatly facilitates cleaning operations.

[0061] Preferably, the base 1 is provided with an auxiliary groove 11 for placing and limiting the inner ring chamber 42, the inner ring grinding head 41 is provided with a temperature heating and cooling device, and the inner ring grinding head 41 is rotatably connected to the impact rod 62 by a thread;

[0062] The temperature heating and cooling device includes a resistance heating plate, a semiconductor cooling plate, a temperature sensor, and a control system. The resistance heating plate, the semiconductor cooling plate, and the temperature sensor are located inside the inner ring grinding head 41. The control system is wirelessly connected to the resistance heating plate, the semiconductor cooling plate, and the temperature sensor. The resistance heating plate, the semiconductor cooling plate, and the temperature sensor can be powered by a built-in battery. The inner ring grinding head 41 can be removed for charging. The control system can be provided with a control knob. The control knob can be provided on the outside of the surrounding grinding chamber 215.

[0063] Representative medicinal materials with hard shells: such as almonds, peach kernels, and jujube kernels. These medicinal materials are usually wrapped in hard shells, and the inner kernels are relatively fragile. Therefore, the suitable grinding method is to first crush the shells by crushing or other methods, and then take out the kernels for grinding. When grinding fruit seed-like medicinal materials with hard shells, first rotate the inner ring chamber 42 to take it out, place the medicinal materials with hard shells inside the inner ring chamber 42, and then move the inner ring chamber 42 around the inner side of the grinding chamber, and place the bottom of the inner ring chamber 42 on the auxiliary groove 11 on the base 1 {this makes the inner ring chamber 42 placed on a horizontal plane, and the medicinal materials are more easily subjected to force during the impact process}, refer to Figure 9As shown, at this time, the impact motor 61 is driven to drive the impact rod 62 on the output end of the impact motor 61 to move downward, and the downward movement of the impact rod 62 drives the inner ring grinding head 41 to move downward, thereby impacting and breaking the shell of the hard-shelled medicinal materials placed in the inner ring chamber 42. During the impact process, the position of the inner ring grinding head 41 can be changed by starting the drive motor 513 to assist in the impact operation of the medicinal materials. The impact motor 61 in this device is an electric cylinder and the electric cylinder has its own storage battery. After the hard-shelled medicinal materials are impacted and opened, the inner shell of the inner ring chamber 42 is taken out, and the kernel is retained in the inner ring chamber 42, and the inner ring chamber 42 is reinstalled into the grinding chamber by rotating it. On the side, at this time, the driving motor 513 is used to drive the slave shaft 524 to rotate, and the rotation of the slave shaft 524 drives the impact motor 61 and the impact rod 62 to rotate synchronously. Since the transmission groove 515 and the inner ring chamber 42 are coaxially arranged, the inner ring grinding head 41 will eventually be driven to perform a circular motion inside the inner ring chamber 42, thereby grinding the kernels inside the inner ring chamber 42. This device can use different methods to grind different medicinal materials. For example: the shells and kernels of the hard-shelled medicinal materials can be mixed and ground as medicinal materials, then the hard-shelled medicinal materials can be directly placed inside the inner ring chamber 42, and a gentle grinding method is adopted. After breaking the shells at a low speed, mixed grinding operations are performed.

[0064] This device can efficiently break the shell and accurately separate the nuts: the unique inner ring chamber 42 and impact structure can quickly break the hard shell and accurately separate the kernel and the shell. The impact motor 61 drives the inner ring grinding head 41 for directional impact, and cooperates with the drive motor 513 to adjust the position, which can efficiently break the shell of medicinal materials such as almonds and peach kernels, avoid damage to the kernel by traditional crushing methods, and improve the complete retention rate of effective ingredients.

[0065] Flexible switching of grinding modes: supports "separate grinding" and "mixed grinding" dual modes. When separation is required, the kernels are first removed from the shells and then ground separately to ensure the purity of the medicinal effect. When mixed use is required, the shells and kernels can be broken simultaneously through low-speed gentle grinding, reducing the number of steps, meeting the needs of different medicinal formulas, and improving the versatility of the device.

[0066] Stable and efficient grinding: The coordinated design of the inner ring chamber 42 and the auxiliary groove 11 of the base 1 ensures a stable chamber during impact and grinding, evenly distributing force to the medicinal material and preventing uneven grinding or equipment damage caused by shaking. The inner ring grinding head 41 is driven by the shaft 524 in a circular motion, achieving 360° grinding without blind spots, improving powder fineness and medicinal material utilization.

[0067] Portable and energy-saving advantages: The impact motor 61 uses an electric cylinder with its own battery, does not require an external power supply, supports offline operation, and is suitable for use in mobile scenarios; precise impact and grinding control reduces ineffective energy consumption, saving more than 20% energy compared to traditional equipment, reducing usage costs.

[0068] Representative medicinal materials of flower and leaf type: such as mint, honeysuckle, chrysanthemum, etc. These medicinal materials are light and fragile, and the active ingredients are mostly volatile substances. Heat will be generated during the grinding process, and the heat generated during the grinding of flower and leaf medicinal materials will directly destroy the active ingredients of the medicinal materials, affecting the extraction and use of their active ingredients. For example, mint, low-temperature and gentle grinding can retain its volatile oil components to the greatest extent and ensure the efficacy. Therefore, when grinding medicinal materials with certain temperature requirements, the temperature-controlled grinding operation can be carried out in real time by starting the temperature heating and cooling device. Flower and leaf medicinal materials are suitable for grinding methods. Low-temperature grinding is used to control the temperature during the grinding process, reduce the temperature during the grinding process, and prevent the volatilization of active ingredients. At the same time, use gentle grinding force to avoid excessive crushing of the medicinal materials into powder and affecting the extraction and use of their active ingredients.

[0069] Animal-based medicinal materials such as keratin and crustaceans, such as tortoise shell, turtle shell, and deer antler, have a hard texture and a dense structure. They are suitable for grinding by first heating them to make them brittle. They are then ground into fine powder using specialized grinding equipment at a high speed and high pressure. For example, tortoise shells are easier to extract the active ingredients after heating and grinding. Therefore, mineral-based medicinal materials such as gypsum, magnet, and natural copper have a hard texture and stable chemical properties, and high temperatures do not easily cause changes in their composition. High-temperature grinding can loosen their texture and grind them into extremely fine powders, which are easier for the human body to absorb and enhance their efficacy. For example, gypsum, after high-temperature grinding, can better play its role in heat-clearing and fire-purging prescriptions. Some seed-based medicinal materials, such as cassia seeds and radish seeds, can be roasted and ground at high temperatures to change their internal structure, destroying the enzymes in the seeds, preventing the components from being enzymatically decomposed during storage, and enhancing their efficacy. The fried Cassia seeds are ground into powder, which has a better effect of clearing the liver and improving eyesight, and can also reduce its side effect of laxative effect. When the Chinese medicine materials need to be ground at high temperature, the medicinal materials are placed in the inner ring chamber 42 for grinding. During the grinding process, the temperature of the inner ring grinding head 41 is controlled by the temperature heating and cooling device to meet the required medicinal material grinding requirements;

[0070] In view of the above description, this device is designed for medicinal materials that require high-temperature grinding. Through unique structural design and temperature control technology, it achieves efficient grinding and improved efficacy. The specific optimization effects are as follows:

[0071] Efficient pretreatment and fine grinding: For hard medicinal materials like tortoise shell and gypsum, they are first treated with high-temperature heating to soften or loosen the texture. Then, the inner ring chamber 42 and specialized grinding equipment combine to grind at high speeds and high pressure, rapidly pulverizing the medicinal materials into an extremely fine powder. Compared to traditional methods, this method increases grinding efficiency by over 40%, significantly shortening operation time and improving work efficiency.

[0072] Precise Temperature Control Maximizes Medicinal Efficacy: A built-in heating and cooling device precisely controls the temperature of the inner grinding head 41, meeting the high-temperature grinding requirements of various medicinal materials. For example, grinding tortoise shell at an appropriate high temperature significantly increases the extraction rate of active ingredients such as collagen. High-temperature stir-frying and grinding of cassia seeds destroys anti-nutritional factors, enhancing liver-clearing and eye-improving effects while minimizing adverse reactions, ensuring the full efficacy of the medicinal material.

[0073] Flexible and versatile, reducing costs: The same inner ring chamber 42 and temperature control system can adapt to a variety of medicinal materials requiring high-temperature grinding, including animals, minerals, and seeds, without the need for frequent equipment or component replacement. This reduces equipment acquisition costs and space usage, while also preventing cross-contamination between different medicinal materials and enhancing the device's versatility and practicality.

[0074] Safe, reliable, and easy to operate: The heating and cooling system features intelligent temperature control and multiple safety features to prevent overheating or loss of control, ensuring the safety of both equipment and operators. The placement and grinding of herbs are simple, with automated high-temperature grinding achieved by pre-setting temperatures and parameters, reducing operational barriers and labor intensity.

[0075] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
