Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine powder drying, in particular to a traditional Chinese medicine powder dryer. Background Art

[0002] The therapeutic effect of traditional Chinese medicine on the body requires strict control of the dosage, which generally refers to the daily dosage of a single medicine for adults. Traditional Chinese medicine is basically a natural plant medicine. In order to facilitate the adjustment and extraction of the effective ingredients in traditional Chinese medicine, it needs to be ground into powder through a traditional Chinese medicine grinding device.

[0003] Chinese patent CN108745472B discloses a typical Chinese medicine grinding device, which discloses that a grinding roller is arranged in a grinding chamber, a fixed ring is arranged under the grinding roller, and a screen is fixedly connected inside the fixed ring. When in use, the grinding roller grinds the Chinese medicine into Chinese medicine powder, and the Chinese medicine powder falls into the screen of the fixed ring for screening. If the particle size of the Chinese medicine powder meets the requirements of the screen, the material is discharged through the screen. On the contrary, if the particle size of the Chinese medicine powder does not meet the requirements of the screen, the Chinese medicine powder on the screen is turned up by the upward spiral blade on the screen to the grinding chamber for further grinding.

[0004] A big problem after the Chinese medicine powder is ground is that in a humid environment, the Chinese medicine powder is more likely to form a "cluster" state. This problem is even worse in a workshop with Chinese medicine steaming and decocting equipment. Although some of the Chinese medicine powder that does not contact the screen can be turned up into the grinding chamber through the upward spiral blade to continue grinding, it still cannot solve the problem well. On the contrary, the screening efficiency will decrease. Summary of the invention

[0005] One of the purposes of the present invention is to solve the problem in the prior art that Chinese medicine powder is prone to form a "clustered" state in a humid environment before screening, which is not conducive to screening.

[0006] A second object of the present invention is to provide a method for drying Chinese medicine powder.

[0007] The third object of the present invention is to provide a Chinese medicine grinding device.

[0008] To achieve one of the above purposes, the present invention adopts the following technical solution: a Chinese medicine powder dryer, which is arranged on a screening plate, and includes a drying shell, in which a connected drying chamber and a heat collection chamber are provided, the heat collection chamber is located above the drying chamber, and an open opening is provided at the bottom of the drying chamber.

[0009] The drying chamber is provided with an electric heating unit, and a fitting bearing is installed at the bottom opening of the drying chamber.

[0010] An opening is provided on the side of the drying shell, the opening is connected to the heat collecting chamber, a baffle is rotatably mounted on the opening, a bias spring is provided at the rotating connection of the baffle, and the baffle seals the opening.

[0011] In the above technical solution, when the embodiment of the present invention is used, the air duct is inserted into the hole of the bottom of the drying shell engaging the bearing, and the electric heating unit in the drying shell is heated, so that the electric heating unit heats the drying chamber of the drying shell.

[0012] When the Chinese medicine powder falls into the screening plate, the outside air is introduced into the drying chamber through the air duct, and the hot air in the drying chamber is blown into the heat collection chamber of the drying shell. The hot air flows into the opening and closing port on the side of the drying shell through the heat collection chamber. The hot air accumulates pressure in the opening and closing port, pushing the baffle of the opening and closing port to rotate, so that the baffle rotates to the screening plate facing the side and below. At this time, the opening and closing port is opened, and the hot air passes through the opening and closing port and blows to the screening plate on the side and below under the restriction of the baffle. The flow rate of the hot air is 800-1000m / s. The temperature of the hot air is 40-50℃.

[0013] The hot air is blown from the opening to the screening plate at the lower side to dry the Chinese medicine powder on the screening plate and prevent the Chinese medicine powder from agglomerating. At the same time, the Chinese medicine powder on the screening plate is blown by the hot air to expand the contact area between the Chinese medicine powder and the hot air, thereby enhancing the drying of the Chinese medicine powder.

[0014] When the hot air blows the screening disc, the drying shell rotates driven by the grinding roller, increasing the blowing area of ​​the hot air on the screening disc and further enhancing the drying of the Chinese medicine powder.

[0015] Furthermore, in an embodiment of the present invention, the top wall of the opening and closing mouth is a blocking surface, and the baffle is rotated by the wind force from the heat collection chamber to open the opening and closing mouth. After the baffle rotates, the outer wall surface of the baffle contacts the blocking surface, and the rotation angle of the baffle is limited by the blocking surface.

[0016] Furthermore, in an embodiment of the present invention, the electric heating unit is bent and spiraled from top to bottom to form a spiral structure, and the electric heating unit is fixed in the drying chamber. The air duct blows out air from bottom to top, and the electric heating unit with a spiral structure can be more exposed to the air blown out from the air duct, so that the formed hot air can quickly reach 40-50°C.

[0017] Furthermore, in an embodiment of the present invention, an inner side wall of the drying chamber is provided with an inwardly extending overlap platform, the electric heating unit is overlapped on the overlap platform, and the electric heating unit is fixed to the overlap platform by snap connection.

[0018] Further, in an embodiment of the present invention, the screening plate has a sleeve shaft, the sleeve shaft is sleeved on the outer surface of the drying shell, and the sleeve shaft is fixed to the drying shell in a snap connection.

[0019] The screening plate also has a coupling bearing and a retaining ring, wherein the retaining ring is fixedly sleeved on the outer surface of the coupling bearing, the sleeve shaft is located in the hole of the coupling bearing, the sleeve shaft and the coupling bearing are connected via a connecting rod, the connecting rods are arranged along the center of the sleeve shaft, gaps are reserved between the connecting rods, the gaps are filled with a screen, and the screen is fixedly connected to the connecting rod, the outer surface of the sleeve shaft, and the inner surface of the hole of the coupling bearing.

[0020] The rotation of the drying shell drives the set shaft and the screen to rotate together. The rotation of the screen is conducive to screening the traditional Chinese medicine powder on the screen and improving the screening efficiency.

[0021] Furthermore, in an embodiment of the present invention, a copper conductive tube is arranged in the hole of the embedded bearing, and the conductive tube is provided with bending parts at the upper and lower parts, and the bending parts are overlapped with the inner ring surface of the embedded bearing, and an insulating layer is provided between the embedded bearing and the conductive tube.

[0022] An insulating sleeve is arranged in the conductive cylinder to prevent the air duct from contacting the conductive cylinder.

[0023] The bending portion is provided with an elastic portion and a lap piece, the elastic portion is located between the lap piece and the hole of the embedded bearing, the bending portion, the lap piece and the elastic portion are connected as a whole, the conductive tube has an electrical connection piece matched with the lap piece, and the electrical connection piece is electrically connected to the electric heating unit through a power line.

[0024] The connecting piece extends between the connecting piece and the bending part, and the connecting piece is overlapped with the connecting piece by the elastic action of the elastic part. The connecting piece has a protruding block, and the connecting piece has a coupling groove. The protruding block is embedded in the coupling groove, so that the connecting piece and the connecting piece are clamped.

[0025] When the air duct of the present invention introduces air into the drying chamber, the elastic portion of the conductive tube is located between the overlap plate and the hole of the embedded bearing (the overlap plate is away from the hole of the embedded bearing), and the external electrical connection plate is clamped with the overlap plate. The overlap plate is not easily affected by the wind force of the air duct, and the overlap plate is not easily separated from the electrical connection plate.

[0026] Furthermore, the centrifugal force generated when the drying shell rotates is limited by the clamping connection formed by the power connection sheet and the overlap sheet, so that the overlap sheet and the power connection sheet are not easily separated from each other.

[0027] In addition, the vibration force generated by the grinding roller on the drying shell causes the overlapping piece to jump, and the power connecting piece is engaged with the overlapping piece, and the overlapping piece is not easy to separate from the power connecting piece. When the overlapping piece jumps up, it is buffered by the elastic part, and with the help of the elastic effect of the elastic part, the protruding block of the overlapping piece is re-embedded into the bottom of the joint groove of the power connecting piece, thereby maintaining the stable operation of the traditional Chinese medicine powder dryer.

[0028] The beneficial effects of the present invention are:

[0029] First, the present invention arranges the electric heating unit in the drying shell. With the help of the restriction of the drying shell on the electric heating unit, it is convenient to gather heat, and the heat is not easy to disperse. Hot air can be quickly blown out from the opening and closing of the drying shell to dry the Chinese medicine powder on the screening plate and avoid "agglomeration" of the Chinese medicine powder.

[0030] The invention gathers hot air in a drying shell, blows the hot air to the Chinese medicine powder in a blowing manner, and the Chinese medicine powder on the screening plate is turned over by the blowing of the hot air, which can not only quickly screen out the Chinese medicine powder that meets the requirements of the screening plate (the particle size requirement is 1000-1200 meshes), but also make the hot air contact with the turned over Chinese medicine powder, thereby expanding the contact area between the Chinese medicine powder and the hot air and strengthening the drying of the Chinese medicine powder.

[0031] The drying shell is driven to rotate by the grinding roller of the prior art Chinese medicine grinding device, which can increase the sweeping area of ​​the hot air on the screening disk and further enhance the drying of the Chinese medicine powder.

[0032] The baffle of the opening and closing mouth seals the opening and closing mouth when the Chinese medicine powder dryer is not working, which can prevent the Chinese medicine powder or dust from floating into the drying chamber and adhering to the electric heating unit, thereby reducing the heating effect of the electric heating unit and affecting the drying of the Chinese medicine powder.

[0033] To achieve the second of the above-mentioned purposes, the present invention adopts the following technical scheme: a method for drying Chinese medicine powder, the Chinese medicine powder drying method is applied to the Chinese medicine powder dryer described in one of the above-mentioned invention purposes, and the Chinese medicine powder drying method comprises the following steps:

[0034] The drying shell is arranged under the grinding roller of the Chinese medicine grinding device, and the air duct of the fan is inserted into the hole of the bottom joint bearing of the drying shell, and the electric heating unit in the drying shell is heated so that the electric heating unit heats the drying cavity of the drying shell.

[0035] When the grinding roller grinds the Chinese medicine into powder and the powder falls into the screening plate, the fan is started to introduce air into the drying chamber through the air duct, and the hot air in the drying chamber is blown into the heat collecting chamber of the drying shell. The hot air flows into the opening on the side of the drying shell through the heat collecting chamber. The hot air accumulates pressure in the opening, pushing the baffle of the opening to rotate, so that the baffle rotates to face the screening plate on the lower side. At this time, the opening is opened, and the hot air passes through the opening, and is restricted by the baffle and blows to the screening plate on the lower side.

[0036] The hot air is blown from the opening to the screening plate at the lower side to dry the Chinese medicine powder on the screening plate and prevent the Chinese medicine powder from agglomerating. At the same time, the Chinese medicine powder on the screening plate is blown by the hot air to expand the contact area between the Chinese medicine powder and the hot air, thereby enhancing the drying of the Chinese medicine powder.

[0037] When the hot air blows the screening disc, the drying shell rotates driven by the grinding roller, increasing the blowing area of ​​the hot air on the screening disc and further enhancing the drying of the Chinese medicine powder.

[0038] Further, in the embodiment of the present invention, when the drying shell rotates, the air duct remains stationary due to the action of the embedded bearing.

[0039] When the air duct introduces air into the drying chamber, the elastic part of the conductive tube is located between the overlapping piece and the hole of the embedded bearing, and the electrical connection piece is clamped with the overlapping piece, the overlapping piece is not easily affected by the wind force of the air duct, and the overlapping piece is not easy to separate from the electrical connection piece.

[0040] Furthermore, the centrifugal force generated when the drying shell rotates is limited by the clamping connection formed by the power connection sheet and the overlap sheet, so that the overlap sheet and the power connection sheet are not easily separated from each other.

[0041] In addition, the vibration force generated by the grinding roller on the drying shell causes the overlapping piece to jump, and the power connecting piece is engaged with the overlapping piece, and the overlapping piece is not easy to separate from the power connecting piece. When the overlapping piece jumps up, it is buffered by the elastic part, and with the help of the elastic effect of the elastic part, the protruding block of the overlapping piece is re-embedded into the bottom of the joint groove of the power connecting piece, thereby maintaining the stable operation of the traditional Chinese medicine powder dryer.

[0042] In order to achieve the third of the above-mentioned objectives, the present invention adopts the following technical solution: a Chinese medicine grinding device, which has the Chinese medicine powder dryer described in one of the above-mentioned invention objectives.

[0043] Furthermore, in an embodiment of the present invention, the traditional Chinese medicine grinding device comprises a grinding box, a grinding chamber is provided in the grinding box, a grinding roller is provided in the grinding chamber, the grinding roller is connected to a driving motor on the grinding box, a grinding gap is formed between the grinding roller and an inner wall of the grinding chamber, the drying shell of the traditional Chinese medicine powder dryer is against the grinding roller, and the rotation of the grinding roller drives the drying shell to rotate.

[0044] A screening plate is arranged at the discharge port at the bottom of the grinding chamber. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] It should be noted that the drawings in the specification are the contents of the specification. The structural shapes, connection relationships, matching relationships, and positional relationships that can be obtained without any doubt in the drawings in the specification should be understood as the contents of the specification.

[0062] A Chinese medicine powder dryer, such as Figure 1 , Figure 2 As shown, the Chinese medicine powder dryer is arranged on the screening plate 20, and the Chinese medicine powder dryer includes a drying shell 10, in which a drying chamber 11 and a heat collecting chamber 12 are connected. The heat collecting chamber 12 is located above the drying chamber 11, and an open opening is provided at the bottom of the drying chamber 11.

[0063] like Figure 2 As shown, the drying chamber 11 has an electric heating unit 30, and the bottom opening of the drying chamber 11 is provided with an embedded bearing 40.

[0064] An opening 13 is provided on the side of the drying shell 10 , and the opening 13 is connected to the heat collecting chamber 12 . A baffle 14 is rotatably installed on the opening 13 , and a bias spring is provided at the rotating connection of the baffle 14 , and the baffle 14 seals the opening 13 .

[0065] Implementation principle: insert the air duct 70 into the hole of the bottom of the drying shell 10 engaging the bearing 22 , and heat the electric heating unit 30 in the drying shell 10 , so that the electric heating unit 30 heats the drying chamber 11 of the drying shell 10 .

[0066] When the Chinese medicine powder falls into the screening plate 20, the outside air is introduced into the drying chamber 11 through the air duct 70, and the hot air in the drying chamber 11 is blown into the heat collecting chamber 12 of the drying shell 10. The hot air flows into the opening 13 on the side of the drying shell 10 through the heat collecting chamber 12. The hot air accumulates pressure in the opening 13, pushing the baffle 14 of the opening 13 to rotate, so that the baffle 14 rotates to face the screening plate 20 at the lower side. At this time, the opening 13 is opened, and the hot air passes through the opening 13 and is restricted by the baffle 14 to blow to the screening plate 20 at the lower side. The flow rate of the hot air is 800-1000 m / s. The temperature of the hot air is 40-50°C.

[0067] The hot air is blown from the opening 13 to the screening plate 20 at the lower side to dry the Chinese medicine powder on the screening plate 20 and prevent the Chinese medicine powder from agglomerating. At the same time, the Chinese medicine powder on the screening plate 20 is blown by the hot air to expand the contact area between the Chinese medicine powder and the hot air, thereby strengthening the drying of the Chinese medicine powder.

[0068] When the hot air blows the screening disc 20, the drying shell 10 is driven by the grinding roller 102 to rotate, thereby increasing the blowing area of ​​the hot air on the screening disc 20 and further enhancing the drying of the Chinese medicine powder.

[0069] The advantages of the present invention are that, first, the present invention arranges the electric heating unit 30 in the drying shell 10, and with the help of the restriction of the drying shell 10 on the electric heating unit 30, it is convenient to gather heat, and the heat is not easy to disperse. Hot air can be quickly blown out from the opening 13 of the drying shell 10 to dry the Chinese medicine powder on the screening plate 20, thereby avoiding "agglomeration" of the Chinese medicine powder.

[0070] The present invention gathers hot air in the drying shell 10, blows the hot air to the Chinese medicine powder in a blowing manner, and the Chinese medicine powder on the screening plate 20 is blown by the hot air, which can not only quickly screen out the Chinese medicine powder that meets the requirements of the screening plate 20 (the particle size requirement is 1000-1200 meshes), but also make the hot air contact with the flying Chinese medicine powder, expand the contact area between the Chinese medicine powder and the hot air, and strengthen the drying of the Chinese medicine powder.

[0071] The drying shell 10 is driven to rotate by the grinding roller 102 of the prior art Chinese medicine grinding device, which can increase the sweeping area of ​​the hot air on the screening plate 20 and further enhance the drying of the Chinese medicine powder.

[0072] When the Chinese medicine powder dryer is not working, the baffle 14 of the opening 13 seals the opening 13 to prevent Chinese medicine powder or dust from floating into the drying chamber 11 and adhering to the electric heating unit 30, thereby reducing the heating effect of the electric heating unit 30 and affecting the drying of the Chinese medicine powder.

[0073] It should be noted that when mint and trillium are dried with hot air at 67 or 68.5 degrees Celsius, their index components will be completely lost, when trichosanthes is dried with hot air at 70 degrees Celsius, their index components will be lost by more than 67%, when Curcuma and white peony are dried with hot air at 70 degrees Celsius, their index components have been lost by more than 60%, when Isatis root is dried with variable temperature hot air at 60 degrees Celsius, its index components have been lost by 59.2%, when rhubarb and siler are dried with variable temperature hot air at 70.2 degrees Celsius, their index components have been lost by more than 40%.

[0074] The above Chinese medicines are dried at room temperature between 40 and 50 degrees Celsius to retain the active ingredients to the maximum extent.

[0075] Therefore, by blowing hot air, it can be guaranteed that the temperature of the Chinese medicine powder on the screening plate 20 will not be higher than 50 degrees Celsius and lower than 40 degrees Celsius.

[0076] Specifically, if Figure 2 As shown, the top wall of the opening 13 is a blocking surface 15, and the baffle 14 is rotated by the wind force from the heat collection chamber 12 to open the opening 13. After the baffle 14 rotates, the outer wall surface 141 of the baffle 14 contacts the blocking surface 15, and the rotation angle of the baffle 14 is limited by the blocking surface 15.

[0077] Specifically, if Figure 2 As shown, the electric heating unit 30 is bent and spiraled from top to bottom to form a spiral structure, and the electric heating unit 30 is fixed in the drying chamber 11. The air duct 70 blows out air from bottom to top, and the electric heating unit 30 with a spiral structure can be more exposed to the air blown out from the air duct 70, so that the formed hot air can quickly reach 40-50°C.

[0078] More specifically, if Figure 2 As shown, the inner wall of the drying chamber 11 is provided with an inwardly extending overlap platform 16 , and the electric heating unit 30 is overlapped on the overlap platform 16 , and the electric heating unit 30 and the overlap platform 16 are fixed by clamping.

[0079] Specifically, if Figure 3As shown, the screening plate 20 has a sleeve shaft 21 , which is sleeved on the outer surface of the drying shell 10 , and the sleeve shaft 21 is fixedly connected with the drying shell 10 in a clamping manner.

[0080] like Figure 3 As shown, the screening plate 20 also has a coupling bearing 22 and a retaining ring 25. The retaining ring 25 is fixedly sleeved on the outer surface of the coupling bearing 22. The set shaft 21 is located in the hole of the coupling bearing 22. The set shaft 21 and the coupling bearing 22 are connected by a connecting rod 23. The connecting rods 23 are arranged along the center of the set shaft 21. Gaps are reserved between the connecting rods 23. The gaps are filled with a screen 24. The screen 24 is fixedly connected to the connecting rod 23, the outer surface of the set shaft 21, and the inner surface of the hole of the coupling bearing 22.

[0081] The rotation of the drying shell 10 drives the set shaft 21 and the screen 24 to rotate together. The rotation of the screen 24 is conducive to screening the Chinese medicine powder on the screen 24, thereby improving the screening efficiency.

[0082] Specifically, if Figure 4 As shown, a copper conductive tube 50 is arranged in the hole of the embedded bearing 40 , and the conductive tube 50 is provided with bending parts at the top and bottom, and the bending parts overlap the inner ring surface of the embedded bearing 40 , and an insulating layer 41 is provided between the embedded bearing 40 and the conductive tube 50 .

[0083] An insulating sleeve 60 is disposed in the conductive tube 50 to prevent the air duct 70 from contacting the conductive tube 50 .

[0084] The bending portion is provided with an elastic portion 52 and a lap piece 51, the elastic portion 52 is located between the lap piece 51 and the hole of the embedded bearing 40, the bending portion, the lap piece 51 and the elastic portion 52 are connected as a whole, the conductive tube 50 has a power connection piece 53 matched with the lap piece 51, and the power connection piece 53 is electrically connected to the electric heating unit 30 through a power line.

[0085] The connecting piece 53 extends between the connecting piece 51 and the bent portion. The connecting piece 51 is overlapped with the connecting piece 53 by the elastic action of the elastic portion 52. The connecting piece 51 has a protruding block, and the connecting piece 53 has a coupling groove. The protruding block is embedded in the coupling groove, so that the connecting piece 53 and the connecting piece 51 are clamped.

[0086] When the air duct 70 of the present invention introduces air into the drying chamber 11, the elastic portion 52 of the conductive tube 50 is located between the overlap plate 51 and the hole of the embedded bearing 40 (the overlap plate 51 is away from the hole of the embedded bearing 40), and the external electrical connection plate 53 is clamped with the overlap plate 51. The overlap plate 51 is not easily affected by the wind force of the air duct 70, and the overlap plate 51 is not easily separated from the electrical connection plate 53.

[0087] Furthermore, the centrifugal force generated when the drying shell 10 rotates is limited by the clamping connection between the power-connecting piece 53 and the connecting piece 51, so that the connecting piece 51 and the power-connecting piece 53 are not easily separated from each other.

[0088] In addition, the vibration force generated by the grinding roller 102 on the drying shell 10 causes the overlapping piece 51 to jump, and the power connecting piece 53 is engaged with the overlapping piece 51, and the overlapping piece 51 is not easily separated from the power connecting piece 53. When the overlapping piece 51 jumps up, it is buffered by the elastic part 52, and with the help of the elastic effect of the elastic part 52, the protruding block of the overlapping piece 51 is re-embedded into the bottom of the joint groove of the power connecting piece 53, so as to maintain the stable operation of the traditional Chinese medicine powder dryer. Example

[0089] A method for drying Chinese medicine powder, the method for drying Chinese medicine powder is applied to the Chinese medicine powder dryer in one of the above-mentioned invention purposes, and the method for drying Chinese medicine powder comprises the following steps:

[0090] The drying shell 10 is arranged under the grinding roller 102 of the Chinese medicine grinding device, and the air duct 70 of the fan is inserted into the hole of the bottom joint bearing 22 of the drying shell 10, and the electric heating unit 30 in the drying shell 10 is heated, so that the electric heating unit 30 heats the drying chamber 11 of the drying shell 10.

[0091] When the grinding roller 102 grinds the Chinese medicine into powder and the powder falls into the screening plate 20, the fan is started to introduce air into the drying chamber 11 through the air duct 70, and the hot air in the drying chamber 11 is blown into the heat collecting chamber 12 of the drying shell 10. The hot air flows into the opening 13 on the side of the drying shell 10 through the heat collecting chamber 12. The hot air accumulates pressure in the opening 13, pushing the baffle 14 of the opening 13 to rotate, so that the baffle 14 rotates to face the screening plate 20 at the lower side. At this time, the opening 13 is opened, and the hot air passes through the opening 13 and is restricted by the baffle 14 to blow to the screening plate 20 at the lower side.

[0092] The hot air is blown from the opening 13 to the screening plate 20 at the lower side to dry the Chinese medicine powder on the screening plate 20 and prevent the Chinese medicine powder from agglomerating. At the same time, the Chinese medicine powder on the screening plate 20 is blown by the hot air to expand the contact area between the Chinese medicine powder and the hot air, thereby strengthening the drying of the Chinese medicine powder.

[0093] When the hot air blows the screening disc 20, the drying shell 10 is driven by the grinding roller 102 to rotate, thereby increasing the blowing area of ​​the hot air on the screening disc 20 and further enhancing the drying of the Chinese medicine powder.

[0094] Specifically, when the drying shell 10 rotates, the air duct 70 is kept stationary under the action of the engaging bearing 40 .

[0095] When the air duct 70 introduces air into the drying chamber 11, the elastic portion 52 of the conductive tube 50 is located between the lap piece 51 and the hole of the embedded bearing 40, and the power connection piece 53 is engaged with the lap piece 51. The lap piece 51 is not easily affected by the wind force of the air duct 70, and the lap piece 51 is not easily separated from the power connection piece 53.

[0096] Furthermore, the centrifugal force generated when the drying shell 10 rotates is limited by the clamping connection between the power-connecting piece 53 and the connecting piece 51, so that the connecting piece 51 and the power-connecting piece 53 are not easily separated from each other.

[0097] In addition, the vibration force generated by the grinding roller 102 on the drying shell 10 causes the overlapping piece 51 to jump, and the power connecting piece 53 is engaged with the overlapping piece 51, and the overlapping piece 51 is not easily separated from the power connecting piece 53. When the overlapping piece 51 jumps up, it is buffered by the elastic part 52, and with the help of the elastic effect of the elastic part 52, the protruding block of the overlapping piece 51 is re-embedded into the bottom of the joint groove of the power connecting piece 53, so as to maintain the stable operation of the traditional Chinese medicine powder dryer.
