[0002] The main purpose of Chinese medicine mixing equipment is to evenly mix different Chinese medicine materials in order to ensure the consistency of Chinese medicine preparations.

[0003] Common stirring equipment usually achieves stirring and mixing of Chinese medicine by rotating the stirring rod on the stirring shaft. In practice, there is a gap between the stirring rod and the inner wall of the barrel to prevent friction between the stirring rod and the barrel wall when rotating, which affects the service life; and during the stirring process, Chinese medicine may adhere to the barrel wall, and the stirring rod cannot scrape off the Chinese medicine on the barrel wall, which will eventually lead to the waste of Chinese medicine and have a certain impact on the proportion of Chinese medicine. Summary of the invention

[0004] In order to prevent the waste of traditional Chinese medicine and reduce the impact on the proportion of traditional Chinese medicine, the present application provides a mixing and stirring device for preparing traditional Chinese medicine.

[0005] The present application provides a mixing and stirring device for preparing traditional Chinese medicine using the following technical solution:

[0007] By adopting the above technical solution, a variety of Chinese medicines are put into the barrel, the stirring shaft is driven to rotate, and the stirring shaft drives all the stirring rods to rotate, so that the Chinese medicines can be stirred and mixed. The Chinese medicines are further stirred by using a vertical stirring column, which is helpful to improve the stirring and mixing effect. During the stirring and mixing process, the driving component drives the two scraping plates on the same stirring column to slide in a direction away from each other. After the two scraping plates are extended, the stirring area is increased, which is helpful to improve the stirring and mixing effect; and when the two scraping plates slide away from each other, the second wedge block moves together with the scraping plate, and the second wedge block slides in the direction of the first wedge block. When the second wedge surface of the second wedge block contacts the first wedge surface, the second wedge block will slide in the direction of the first wedge surface, and the second wedge block will drive the first mounting plate to slide in the horizontal direction, that is, the first bristles on the surface of the first mounting plate extend out of the scraping plate and contact the inner wall of the barrel body. With the cooperation of the second bristles, the Chinese medicine adhered to the inner wall of the barrel can be scraped off, so that the Chinese medicine on the inner wall falls and is mixed, which is helpful to prevent the waste of Chinese medicine and ensure the proportion of Chinese medicine.

[0008] Preferably, when the scraper plates on the same stirring column slide in directions away from each other, the scraper plates on adjacent stirring columns abut against each other in the vertical direction.

[0009] By adopting the above technical solution, when the scraper plates on the stirring column slide in the direction away from each other, the scraper plates in the vertical direction abut against each other, that is, at this time in the same vertical direction, all the first bristles and the second bristles can cover the vertical length of the inner wall of the barrel body, which can ensure that the traditional Chinese medicine on the inner wall of the barrel body is scraped off cleanly, which helps to further prevent the waste of traditional Chinese medicine.

[0011] By adopting the above technical solution, the driving rod moves, driving the linkage block to slide to the side away from the stirring shaft, that is, to slide toward the inner wall of the barrel body. At this time, the linkage block can drive the scraper plate to slide through the connecting rod. Similarly, when the driving rod drives the linkage block to slide in the direction close to the stirring shaft, the scraper plate can be reset through the connecting rod.

[0012] Preferably, a connecting plate is integrally formed on the side of the stirring column away from the stirring shaft, a connecting groove is provided in the connecting plate, a second mounting plate is slidably provided on the connecting plate in the connecting groove, the second bristles are mounted on the second mounting plate, the linkage block is also fixedly connected to the first connecting rod, a second connecting rod is sleeved on the first connecting rod, a plug-in groove is provided in the second connecting rod, the first connecting rod is plug-matched with the plug-in groove, the second connecting rod passes through the connecting plate and extends into the connecting groove and is fixedly connected to the second mounting plate; a reset spring is provided on the connecting plate located in the connecting groove, the length direction of the reset spring is consistent with the sliding direction of the second mounting plate, one end of the reset spring is connected to the second mounting plate, and the other end of the reset spring is connected to the inner wall of the connecting groove.

[0013] By adopting the above technical solution, when the linkage block slides, the second mounting plate is driven to slide through the cooperation of the first connecting rod and the second connecting rod, so that the second bristles can slide outward and contact the inner wall of the barrel body. When the linkage block slides in the opposite direction, the second mounting plate can be reset under the action of the reset spring. Like the first bristles, the second bristles are in a reciprocating sliding state, which can prevent Chinese medicine from being collected on the second bristles.

[0014] Preferably, the box body is located inside the stirring shaft and is vertically provided with an installation shaft, the driving member is configured as a driving disk, the number of the driving disks is the same as the number of the stirring rod groups and corresponds one to one, the driving disk is rotatably connected to the installation shaft, a plurality of hinged rods are eccentrically arranged on the driving disk, the hinged rods are hinged to the corresponding driving rods; the stirring shaft is provided with a linkage member for driving the driving disk to rotate relative to the stirring shaft.

[0015] By adopting the above technical solution, the linkage component enables the driving disk to rotate relative to the stirring shaft. When the driving disk rotates, it can drive the driving rod to move, and then drive the linkage block to slide, and finally realize the movement of the scraper plate.

[0016] Preferably, the inner wall of the stirring shaft is provided with a sliding groove along its own arc, and the edge of the driving disk is provided with a plug-in block, which is plugged into the sliding groove to form a sliding fit, and the stirring shaft is provided with a compression spring in the sliding groove, one end of the compression spring is connected to the plug-in block, and the other end of the compression spring is connected to the inner wall of the sliding groove. In the initial state, under the action of the compression spring, the plug-in block abuts against the end wall of the sliding groove, and the driving disk and the stirring shaft rotate synchronously; the linkage part is provided as a blocking rod, the blocking rod is horizontally arranged, and the blocking rod is lifted and lowered on the mounting shaft, an abutment rod is eccentrically arranged on the driving disk, and the abutment rod is vertically arranged, and a lifting component for driving the blocking rod to rise is provided in the stirring shaft.

[0017] By adopting the above technical scheme, under the action of the compression spring, the plug-in block always abuts against the end wall of the sliding groove. When the stirring shaft rotates, the driving disc rotates synchronously with the stirring shaft. After the driving disc rotates a certain angle, the abutting rod abuts against the blocking rod. Under the blocking action of the blocking rod, the driving disc will not continue to rotate with the stirring shaft, that is, at this time, the driving disc will rotate relative to the stirring shaft, thereby driving the driving rod to move; when the driving disc does not rotate, the plug-in block slides in the sliding groove, the compression spring is compressed, and then the lifting assembly drives the blocking rod to rise, and the blocking rod gradually separates from the abutting rod. Then, under the action of the compression spring, the plug-in block slides quickly in the sliding groove and abuts against the end wall of the sliding groove. At this time, the driving disc is reset relative to the stirring shaft, and the driving rod is reset; that is, in practice, the medicine scraper is in a reciprocating sliding state. If the medicine scraper is stationary and does not slide, and the first bristles are always in contact with the inner wall of the barrel body, more Chinese medicine will be squeezed and accumulated at the first bristles, affecting the stirring effect, and the scraping effect is not good.

[0018] Preferably, the lifting assembly includes a lifting rod lifted in the installation shaft and a sliding rod driving the lifting rod to lift, a lifting slot is provided in the installation shaft along the vertical direction, the lifting rod slides in the lifting slot, the blocking rod is fixedly connected to the lifting rod, the installation shaft is located at the upper end of the lifting rod and a first abutment spring is provided, one end of the first abutment spring is connected to the lifting rod, and the other end of the first abutment spring is connected to the inner wall of the lifting slot; a sliding slot is radially provided in the driving disk, the sliding rod slides in the sliding slot, the lower end of the lifting slot is connected to the sliding slot, a third wedge-shaped surface is formed at the lower end of the lifting rod, a fourth wedge-shaped surface is formed on the side of the sliding rod close to the lifting rod, the driving disk is located in the sliding slot and a second abutment spring is provided, and the second abutment spring The cam is provided with a second end which is connected to the inner wall of the slide groove and the second end of the second end which is connected to the slide groove. The inner wall of the agitator shaft is hinged with an inclined plate by a torsion spring, and one side of the inclined plate is provided with an abutment surface. In an initial state, the side of the inclined plate which is away from the abutment surface overlaps the inner wall of the agitator shaft. When the agitator shaft rotates and the driving disk does not rotate, the end of the sliding rod abuts with the abutment surface of the inclined plate. Under the action of the inclined plate, the sliding rod slides toward the direction of the installation shaft, and the fourth wedge surface abuts with the third wedge surface. The lifting rod rises, and the blocking rod and the abutment rod are disengaged. Subsequently, under the action of the compression spring, the plug-in block is reset, the driving disk rotates, the sliding rod abuts with the inclined plate and drives the inclined plate to rotate until the sliding rod is disengaged from the inclined plate.

[0019] By adopting the above technical solution, when the driving disk rotates and the abutment rod abuts against the blocking rod, the stirring shaft continues to rotate, and the driving disk does not rotate. When the stirring shaft rotates, the sliding rod of the driving disk will gradually contact the abutment surface of the inclined plate on the inner wall of the stirring shaft. Because the side of the inclined plate facing away from the abutment surface is overlapped on the inner wall of the stirring shaft, the inclined plate will not rotate with the movement of the sliding rod. At this time, the inclined plate plays the role of a wedge surface, and the sliding rod will slide in the direction of the installation shaft and enter the lifting groove. The fourth wedge surface abuts against the third wedge surface, driving the lifting rod to rise , the lifting rod drives the blocking rod to rise, and the blocking rod gradually separates from the abutting rod. After separation, the driving disk can rotate, and under the action of the compression spring, the plug-in block slides toward the end of the sliding groove. At this moment, the rotation speed of the driving disk is greater than the speed of the stirring shaft, and the plug-in block will abut against the end of the sliding groove. Thereafter, the driving disk and the stirring shaft rotate synchronously. During the resetting process of the plug-in block, the sliding rod will also contact the reverse and inclined plates, which will drive the inclined plates to rotate to avoid the movement of the sliding rod. After the sliding rod and the inclined plate separate, the inclined plate is reset under the action of the torsion spring.

[0020] Preferably, a fifth wedge surface is formed on the lower side of the blocking rod, and a sixth wedge surface is formed on the upper side of the abutment rod. When the abutment rod and the blocking rod abut against each other, the sixth wedge surface is located on the upper side of the fifth wedge surface. When the sliding rod drives the lifting rod to rise, the sixth wedge surface of the abutment rod abuts against the fifth wedge surface of the blocking rod. At this time, the sliding rod and the inclined plate are disengaged. Then, under the action of the compression spring, the driving disk rotates, and the abutment rod continues to drive the lifting rod to rise through the cooperation of the sixth wedge surface and the fifth wedge surface, and the abutment rod and the blocking rod are disengaged.

[0021] By adopting the above technical solution, when the sliding of the sliding rod drives the lifting rod to slide, the lifting rod drives the blocking rod to rise. At this time, the maximum rising stroke of the lifting rod reaches the abutment of the sixth wedge surface and the fifth wedge surface. After the sliding rod is separated from the inclined plate, the sliding rod is reset under the action of the second abutment spring; at this time, under the action of the compression spring, the driving plate rotates, that is, the abutment rod will continue to drive the blocking rod to slide upward until it is separated from the blocking rod; because if the sliding rod drives the blocking rod and the abutment rod to separate, at the moment of separation, the compression spring will drive the driving plate to rotate, and at this time the sliding rod is inserted into the lifting groove, the driving plate cannot rotate, and the lifting groove wall of the driving plate will contact the sliding rod and generate friction, affecting the disengagement effect of the sliding rod.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the Chinese medicine is mixed and stirred, the medicine scraper is driven by the driving assembly to slide and extend for stirring. At the same time, when the medicine scraper slides, under the action of the first wedge block and the second wedge block, the first mounting plate gradually drives the first bristle to extend and contact the inner wall of the barrel body, so that the Chinese medicine attached to the inner wall of the barrel body can be scraped off and dropped to continue the mixing operation, which helps to prevent the waste of Chinese medicine and ensure the proportion of Chinese medicine. The medicine scraper moves back and forth, that is, the first bristle is not always in contact with the inner wall of the barrel body, which can prevent the Chinese medicine from being squeezed into the bristles, but affects the scraping effect;

[0024] 2. With the help of the rotation of the driving disk, all driving rods are driven to move synchronously, and the driving rods drive the linkage block to slide, and the linkage block can realize the sliding of the scraper plate through the connecting rod;

[0025] 3. The blocking rod on the mounting shaft blocks the abutting rod on the driving disc, so that the driving disc stops rotating, and the driving disc rotates relative to the stirring shaft, thereby driving the driving rod to move. When the stirring shaft rotates relative to the driving disc, the inclined plate gradually abuts against the sliding rod, and the inclined plate causes the sliding rod to slide toward the mounting shaft. The sliding rod extends into the mounting shaft and drives the lifting rod to rise, thereby causing the blocking rod and the abutting rod to disengage. Under the action of the compression spring, the driving disc will reset relative to the stirring shaft, and then move synchronously with the stirring shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-10 This application is described in further detail.

[0038] The embodiment of the present application discloses a mixing and stirring device for preparing traditional Chinese medicine.

[0040] Reference Figure 2 and Figure 3There are multiple stirring rod groups distributed on the stirring shaft 2 in the vertical direction, and any stirring rod group contains at least three stirring rods 3. Four stirring rods are taken as an example for explanation in this application. The four stirring rods 3 are all fixedly installed on the stirring shaft 2, and the four stirring rods 3 are arranged in a circular array on the circumferential side of the stirring shaft 2; the structures of all the stirring rods 3 are the same, and one of them is taken as an example for explanation. A stirring column 4 is installed in the vertical direction at one end of the stirring rod 3 away from the stirring shaft 2, and the stirring column 4 is hollow. Two scraper plates 5 are lifted and lowered in the stirring column 4, and the two scraper plates 5 slide synchronously in the directions away from and approaching each other, and a driving component 6 for driving the two scraper plates 5 to slide is provided in the stirring rod 3.

[0041] Reference Figure 3 , Figure 4 and Figure 5 , a receiving groove 51 is provided in the medicine scraper plate 5, and a first mounting plate 52 is provided in the receiving groove 51 and slides in the horizontal direction on the medicine scraper plate 5, and a sliding groove 511 is provided on the opposite side wall of the medicine scraper plate 5 located in the receiving groove 51, and sliding blocks 521 that slide and cooperate with the sliding groove 511 are integrally formed on both sides of the first mounting plate 52, and a return spring 512 is installed in the medicine scraper plate 5 located in the sliding groove 511, and the length direction of the return spring 512 is consistent with the sliding direction of the first mounting plate 52, one end of the return spring 512 is connected to the sliding block 521, and the other end is connected to the inner wall of the sliding groove 511, and a first bristle 522 is installed on the side of the first mounting plate 52 close to the inner wall of the barrel body 1; a first wedge block 41 is fixedly connected to the inner wall of the stirring column 4, and the first wedge block 41 is located on the first mounting plate 52 is on the side away from the first bristles 522, a first wedge surface 411 is formed on the lower side of the first wedge block 41, an avoidance groove is provided on the side of the scraper plate 5 close to the first wedge block 41, the first wedge block 41 extends into the accommodating groove 51 from the avoidance groove, and a second wedge block 53 is fixedly connected to the side of the first mounting plate 52 close to the first wedge block 41, and a second wedge surface 531 is formed on the upper side of the second wedge block 53; when the two scrapers 5 slide in the direction away from each other, the second wedge block 53 gradually abuts against the first wedge block 41, and under the cooperation of the first wedge surface 411 and the second wedge surface 531, the first mounting plate 52 slides and drives the first bristles 522 to extend out of the scraper plate 5 and contact the inner wall of the barrel body 1; a second bristle 42 is installed on the side of the stirring column 4 close to the inner wall of the barrel body 1.

[0042] Put a variety of Chinese medicines into the barrel 1, rotate the stirring shaft 2, drive all the stirring rods 3 to rotate, and mix and stir the Chinese medicines. At the same time, the vertical stirring column 4 can also stir the Chinese medicines, which helps to improve the mixing and stirring effect; during the mixing and stirring process, the driving component 6 drives the two scraping plates 5 on the same stirring column 4 to slide in a direction away from each other. After the two scraping plates 5 extend out of the stirring column 4, the stirring area can be increased to further improve the stirring effect. When the scraping plates 5 slide, the first mounting plate 52 slides outward, that is, the first bristles 522 extend out of the scraping plates 5 and contact the inner wall of the barrel 1. The second bristles 42 can be used to scrape the Chinese medicines on the inner wall of the barrel 1, so that the Chinese medicines fall and continue to be mixed, which helps to prevent the waste of Chinese medicines and ensure the proportion of Chinese medicines. In practice, if the first bristles 522 are always in contact with the inner wall of the barrel body 1, because the bristles are made of flexible material and there are gaps between the bristles, the Chinese medicine will accumulate between the bristles during the scraping process. Therefore, when the medicine scraping plate 5 is in a reciprocating sliding process, the first bristles 522 are also in a reciprocating sliding motion, and there is intermittent contact between the first bristles 522 and the inner wall of the barrel body 1, which helps to prevent the Chinese medicine from being collected on the first bristles 522.

[0043] When the medicine scraping plates 5 on the same stirring column 4 slide away from each other, in the vertical direction, the medicine scraping plates 5 on the adjacent stirring columns 4 abut against each other. That is, at this time, in the same vertical direction, the area covered by all the first bristles 522 and the second bristles 42 is larger, which helps to improve the scraping effect of the Chinese medicine.

[0044] Reference Figure 2 , Figure 3 and Figure 4 A connecting plate 43 is integrally formed on one side of the stirring column 4 away from the stirring shaft 2 , a connecting groove 431 is defined in the connecting plate 43 , a second mounting plate 44 is slidably disposed in the connecting groove 431 , and the second bristles 42 are mounted on the second mounting plate 44 .

[0045] Reference Figure 2 , Figure 3 and Figure 4 The driving assembly 6 includes a linkage block 61 and two connecting rods 62. The two scraping plates 5 in one stirring column 4 correspond to one driving assembly 6. The linkage block 61 is slidably connected in the corresponding stirring rod 3. The sliding direction of the linkage block 61 is consistent with the length direction of the stirring rod 3. The two connecting rods 62 correspond to the two scraping plates 5 one by one. One end of the connecting rod 62 is hinged to the corresponding scraping plate 5, and the other end of the connecting rod 62 is hinged to the linkage block 61. When the linkage block 61 slides away from the stirring shaft 2, the linkage block 61 can drive the scraping plate 5 to slide through the connecting rod 62. A driving rod 7 for driving the linkage block 61 to slide is provided in the stirring rod 3. The end of the driving rod 7 is hinged to the linkage block 61. A driving member for driving the driving rod 7 to move is provided in the stirring shaft 2.

[0046] When the driving member drives the driving rod 7 to move toward the stirring shaft 2 , the driving rod 7 drives the linkage block 61 to slide, and the linkage block 61 can then realize the sliding of the medicine scraping plate 5 through the connecting rod 62 .

When the linkage block 61 slides, the cooperation between the first connecting rod 20 and the second connecting rod 30 drives the second mounting plate 44 to slide, so that the second bristles 42 can slide outward and contact the inner wall of the barrel body 1. In practice, when the linkage block 61 slides, it will first drive the first connecting rod 20 to slide relative to the second connecting rod 30, until the end of the first connecting rod 20 moves to the bottom wall of the plug-in slot 301, and then the first connecting rod 20 drives the second connecting rod 30 to slide synchronously, so as to realize the sliding of the second mounting plate 44. The connecting plate 43 is located in the connecting groove 431 and is provided with a reset spring 40. The length direction of the reset spring 40 is consistent with the sliding direction of the second mounting plate 44. One end of the reset spring 40 is connected to the second mounting plate 44, and the other end of the reset spring 40 is connected to the inner wall of the connecting groove 431. When the linkage block 61 slides in the opposite direction, the second mounting plate 44 can be reset under the action of the reset spring 40.

[0048] Reference Figure 2 , Figure 3 and Figure 7 A mounting shaft 12 is fixedly installed in the barrel body 1, and the mounting shaft 12 is vertically arranged and is located in the stirring shaft 2. The driving member is provided with a driving disk 8. The number of driving disks 8 is the same as the number of stirring rod groups and corresponds one to one. The driving disk 8 is rotatably connected to the mounting shaft 12, and a plurality of hinged rods 81 are installed on the driving disk 8. The hinged rods 81 are the same in number as the stirring rods 3 in the stirring rod group. In the present application, four hinged rods 81 are arranged, and the hinged rods 81 are eccentrically arranged on the driving disk 8. The four hinged rods 81 correspond one to one to the four driving rods 7. The end of the driving rod 7 away from the linkage block 61 is hinged to the corresponding hinged rod 81. The driving disk 8 rotates a certain angle relative to the stirring shaft 2 to realize the movement of the driving rod 7. A linkage member is provided in the stirring shaft 2 to drive the driving disk 8 to rotate relative to the stirring shaft 2.

[0049] Reference Figure 7 and Figure 8A sliding groove 21 is provided on the inner wall of the stirring shaft 2 along its arc shape, and a plug-in block 82 is integrally formed on the edge of the driving disk 8. The plug-in block 82 is plugged into the sliding groove 21 to form a sliding fit. The stirring shaft 2 is located in the sliding groove 21 and a compression spring 211 is installed. The compression spring 211 is an arc spring. The arc shape of the compression spring 211 is consistent with the arc shape of the inner wall of the stirring shaft 2. One end of the compression spring 211 is connected to the plug-in block 82, and the other end of the compression spring 211 is connected to the inner wall of the sliding groove 21. In the initial state, under the action of the compression spring 211, the plug-in block 82 and the end of the sliding groove 21 abut, and at this time, the driving disk 8 will rotate synchronously with the stirring shaft 2.

[0050] The linkage part is set as a blocking rod 9, which is set horizontally. The blocking rod 9 is lifted and lowered on the installation shaft 12. A contact rod 83 is installed on the driving disk 8 in the vertical direction. The contact rod 83 is eccentrically set to the driving disk 8. A lifting component 10 for driving the blocking rod 9 to rise is set in the stirring shaft 2. When the driving disk 8 rotates a certain angle with the stirring shaft 2, the abutment rod 83 and the blocking rod 9 abut against each other. Under the blocking action of the blocking rod 9, the driving disk 8 stops rotating. At this time, the plug-in block 82 slides in the sliding groove 21, and the compression spring 211 is compressed. At this time, the driving disk 8 and the stirring shaft 2 rotate relative to each other, realizing the movement of the driving rod 7, and the scraper plate 5 slides accordingly; then the lifting assembly 10 drives the blocking rod 9 to rise, and the blocking rod 9 gradually disengages from the abutment rod 83. At this time, under the action of the compression spring 211, the plug-in block 82 slides quickly in the sliding groove 21 and abuts against the end wall of the sliding groove 21. At this time, the driving disk 8 is reset relative to the stirring shaft 2, the driving rod 7 is reset, and the scraper plate 5 and the second mounting plate 44 are reset.

[0051] Reference Figure 8 and Fig. 9The lifting assembly 10 includes a lifting rod 101 and a sliding rod 102 for driving the lifting rod 101 to lift. A lifting groove 121 is provided in the installation shaft 12 in the vertical direction. The lifting rod 101 slides with the lifting groove 121. The blocking rod 9 is fixedly connected to the lifting rod 101. The installation shaft 12 is located in the lifting groove 121 and is provided with a first abutment spring 122. The first abutment spring 122 is located on the upper side of the lifting rod 101. One end of the first abutment spring 122 is connected to the lifting rod 101, and the other end of the first abutment spring 122 is connected to the inner wall of the lifting groove 121. The driving disk 8 is provided with a sliding groove 84 in the radial direction. When the abutment rod When 83 abuts against the blocking rod 9, the slide groove 84 is connected to the lower end of the lifting groove 121, and the sliding rod 102 slides in the slide groove 84; a third wedge-shaped surface 1011 is formed at the lower end of the lifting rod 101, and a fourth wedge-shaped surface 1022 is formed on the side of the sliding rod 102 close to the lifting rod 101; the driving disk 8 is located in the slide groove 84 and is equipped with a second abutment spring 85, which is sleeved on the sliding rod 102, one end of the second abutment spring 85 is connected to the inner wall of the slide groove 84, and a limiting plate 1021 is integrally formed on the peripheral side of the sliding rod 102, and the other end of the second abutment spring 85 is connected to the limiting plate 1021.

[0052] The inner wall of the stirring shaft 2 is provided with a rotating groove 22. The stirring shaft 2 is located in the rotating groove 22 and is rotatably connected to a rotating shaft 23. The rotating shaft 23 is vertically arranged. An inclined plate 24 is rotatably connected to the rotating shaft 23 through a torsion spring. A contact surface 241 is formed on one side of the inclined plate 24. In the initial state, under the action of the torsion spring, the side of the inclined plate 24 away from the contact surface 241 overlaps the notch of the rotating groove 22 of the stirring shaft 2. When the contact rod 83 and the blocking rod 9 are in contact, the driving disc 8 does not rotate, the stirring shaft 2 rotates, and the end of the sliding rod 102 gradually contacts the contact surface 241 of the inclined plate 24. In the inclined state of the contact surface 241 of the inclined plate 24, the sliding rod 102 will slide into the lifting groove 121, and the fourth wedge surface 1022 will contact the third wedge surface 1011, the lifting rod 101 will rise, and the blocking rod 9 and the contact rod 83 will be separated; then, under the action of the compression spring 211, the plug-in block 83 is inserted into the lifting groove 121. 82 slides toward the end of the sliding groove 21. At this moment, the rotation speed of the driving disk 8 is greater than the speed of the stirring shaft 2, and the plug-in block 82 will abut against the end of the sliding groove 21. Thereafter, the driving disk 8 and the stirring shaft 2 rotate synchronously. During the resetting process of the plug-in block 82, the sliding rod 102 will also contact the reverse and inclined plate 24, which will drive the inclined plate 24 to rotate to avoid the movement of the sliding rod 102. After the sliding rod 102 and the inclined plate 24 are disengaged, the inclined plate 24 is reset under the action of the torsion spring.

[0053] Reference Figure 8 and Fig.10A fifth wedge surface 91 is formed on the lower side of the blocking rod 9, and a sixth wedge surface 831 is formed on the upper side of the abutting rod 83. When the abutting rod 83 abuts against the blocking rod 9, the sixth wedge surface 831 is located on the upper side of the fifth wedge surface 91. When the sliding rod 102 drives the lifting rod 101 to rise, the sixth wedge surface 831 of the abutting rod 83 abuts against the fifth wedge surface 91 of the blocking rod 9. At this time, the sliding rod 102 is disengaged from the inclined plate 24. Under the action of the second abutting spring 85, the sliding rod 102 is reset. At this time, under the action of the compression spring 211, the driving disk 8 rotates, and the abutting rod 83 cooperates with the fifth wedge surface 91 through the sixth wedge surface 831 to make the lifting rod 101 continue to rise, and finally the abutting rod 83 and the blocking rod 9 are disengaged.

[0054] If the sliding rod 102 drives the blocking rod 9 and the abutting rod 83 to disengage, at the moment of disengagement, the compression spring 211 will drive the driving plate 8 to rotate, and at this time, the sliding rod 102 is inserted into the lifting groove 121, and the driving plate 8 cannot rotate. The lifting groove 121 wall of the driving plate 8 will contact the sliding rod 102 and generate friction, which affects the disengagement effect of the sliding rod 102. Therefore, the lifting rod 101 is first raised to make the fifth wedge surface 91 contact the sixth wedge surface 831, and then the sliding rod 102 is separated from the lifting groove 121, and the compression spring 211 is used to separate the abutting rod 83 and the blocking rod 9, so that the movement of each component can be smoother.

[0055] The implementation principle of a mixing and stirring device for preparing traditional Chinese medicine in an embodiment of the present application is as follows: the traditional Chinese medicine is put into the barrel body 1, the stirring shaft 2 rotates, and the stirring rod 3 can mix and stir the traditional Chinese medicine. During this process, the medicine scraper 5 slides back and forth, and when the medicine scraper 5 extends out of the stirring column 4, the first bristles 522 also extend out of the medicine scraper 5, and at the same time, the second mounting plate 44 slides outward, and the second bristles 42 extend out of the connecting plate. The first bristles 522 and the second bristles 42 scrape off the traditional Chinese medicine on the inner wall of the barrel body 1 to prevent the traditional Chinese medicine from adhering to the inner wall, causing waste of traditional Chinese medicine and reducing the impact on the proportion of traditional Chinese medicine.
