Description

Technical Field

[0001] The present invention relates to the technical field of crushing devices, and particularly to a Chinese herbal medicine crushing device. Background Art

[0002] Traditional Chinese medicine decoction pieces are processed from Chinese herbal medicines according to traditional Chinese medicine theory and can be directly used in clinical practice of traditional Chinese medicine. During the processing of traditional Chinese medicine decoction pieces, it is usually necessary to crush the medicinal materials. For Chinese medicines with a large processing volume and relatively hard texture, such as crustaceans, bones, shells, and hard plant seeds, a jaw crusher is generally used to crush the medicinal materials.

[0003] The Chinese patent document with the authorization announcement number CN220737669U discloses a jaw crusher for medicinal material processing, including a processing box. Moving jaw plates and static jaw plates are respectively installed at both ends inside the processing box. The moving jaw plates and the static jaw plates are parallel to each other. Feed inlets and discharge outlets are respectively installed at the upper and lower ends of the processing box. A cleaning mechanism for cleaning is installed inside the moving jaw plates and the static jaw plates. An eccentric shaft is installed at the upper end of the moving jaw plate. The eccentric shaft is movably installed through the inside of the processing box. Driving wheels are respectively installed on both sides of the processing box. The driving wheels are fixedly connected to the eccentric shaft. A motor is installed outside the processing box. The motor is connected to the driving wheels. After the moving jaw plates cooperate with the static jaw plates to complete the processing of the raw materials, the user can inject water flow into the inside of the main tank through a hose. As the water flow is continuously injected, finally, the water flow can push the sealing block and the sealing plate, thereby opening the through hole. Then, the water flow can flow along the sealing plate and the guiding groove on the surfaces of the moving jaw plates and the static jaw plates, thereby flushing their surfaces and washing away the residual medicinal liquid on the surfaces, so as to prevent the mixing of medicinal properties when processing other raw materials later.

[0004] In the above technical solution, after crushing the medicinal materials, the moving jaw plates and the static jaw plates are washed by water flow, which can achieve a certain cleaning effect to a certain extent. However, there are still corresponding problems. When washing the medicinal materials with water flow, it is necessary for the water flow to cover all the crushing surfaces of the entire moving jaw plates and the static jaw plates to be cleaned thoroughly. Obviously, a larger water flow is required to ensure that the water flow can cover all the surfaces to be cleaned. After the cleaning is completed, it is also necessary to dry the moving jaw plates and the static jaw plates. The bottom of the moving jaw plates and the static jaw plates, that is, the key parts where the crushing force is applied, is prone to adhesion of medicinal materials, and it is difficult to remove these adhered medicinal materials only by water flow flushing. Summary of the Invention

[0005] The present invention provides a Chinese herbal medicine crushing device, aiming to solve the problem that it is difficult to clean the crusher thoroughly after crushing the medicinal materials in the related technology.

[0006] A Chinese medicinal material crushing device comprises: a jaw crusher, the jaw crusher has a static jaw plate and a dynamic jaw plate, and the static jaw plate and the dynamic jaw plate are provided with a plurality of mutually meshing crushing teeth;

[0007] A cleaning component is provided near the bottom of the static jaw plate. The cleaning component includes a cleaning plate, a rotating connection piece and a lifting piece. A vertical groove is provided near the bottom of each crushing tooth on the static jaw plate. The rotating connection piece is equipped with two rotatable movable parts at the front and rear. Each movable part is equipped with a resettable vertical connecting shaft. The cleaning plate is firmly installed on the connecting shaft. The movable end of the rotating connection piece is located on the inner side of the vertical groove. The cleaning plate is attached to the outer wall of the crushing tooth. A dust cover is provided on the outer periphery of each cleaning plate. The lifting piece drives the rotating connection piece to move up and down in the vertical groove, thereby driving the cleaning plate to clean the crushing teeth of the static jaw plate.

[0008] A transverse groove connected to the vertical groove is provided on the crushing tooth of the static jaw plate. A stop member for deflecting the cleaning plate toward the movable jaw plate is provided between one side of the transverse groove and the movable part of the rotating connecting member. A pushing member for pushing the rotating connecting member to slide in the transverse groove is installed on the lifting member. When the rotating connecting member slides from the vertical groove into the transverse groove, the cleaning plate will reset and leave the outer wall of the crushing tooth.

[0009] The effect is as follows: after the jaw crusher completes the crushing operation of the medicinal materials, the cleaning plate is driven down by the lifting mechanism to achieve thorough cleaning of the static jaw plate; the rotating connecting member is moved in the transverse groove by the setting pusher, and when the rotating connecting member moves toward one side of the transverse groove, the cleaning plate will be separated from the tooth surface contact with the static jaw plate crushing teeth, and the stopper ensures that the cleaning plate undergoes necessary deflection during the separation process. In the process of the static jaw plate and the moving jaw plate approaching each other, the cleaning plate will tilt to the same angle as the moving jaw plate, and move from the tooth top to the tooth bottom of the moving jaw plate crushing teeth. This design ensures that when cleaning the moving jaw plate, the cleaning plate can cover every corner, thereby eliminating the cleaning dead corner. After the cleaning work is completed, the cleaning plate can be reset to the dust cover under the joint action of the lifting member and the pushing member. This design effectively prevents the powder generated during the crushing process of the medicinal materials from adhering to the cleaning plate, ensuring the cleanliness of the equipment and the purity of the medicinal materials.

[0010] Preferably, a torsion spring is arranged between the connecting shaft and the movable rod of the rotating connecting member. When the vertical groove of the rotating connecting member enters the horizontal groove and slides from one end of the horizontal groove to the other end, the cleaning plate disengages from the contact with the crushing teeth of the static jaw plate, and the cleaning plate is reset under the action of the torsion spring. At this time, the cleaning plate is basically in a state perpendicular to the front viewing reference plane. When the moving jaw plate approaches the static jaw plate, the cleaning plate contacts the tooth tops of the crushing teeth of the moving jaw plate, thereby cleaning the crushing teeth of the moving jaw plate.

[0011] Preferably, the lifting member is an electric telescopic rod, which is located inside the crushing teeth of the static jaw plate. The rotary connecting member is installed at the movable end of the electric telescopic rod. The electric telescopic rod drives the rotary connecting member to slide in the vertical groove, thereby driving the cleaning plate to lift and clean the static jaw plate.

[0012] Preferably, the rotary connecting member includes a sleeve. Two movable rods are rotatably arranged inside the sleeve. Torsion springs are installed between the movable rods and the sleeve. One end of the torsion spring is connected to the bottom of the sleeve, and the other end is connected to the movable rod. When the rotary connecting member moves from one end of the horizontal groove to the other end, the stopping member causes one end of the movable rod to rotate, thereby deflecting the cleaning plate.

[0013] Preferably, the rotation of the movable rod deflects the cleaning plate to be parallel to the movable jaw plate. When the deflection angle of the cleaning plate is the same as the included angle between the movable jaw plate and the static jaw plate, when the cleaning plate cleans the crushing teeth on the movable jaw plate, the cleaning plate can move from the tooth top to the tooth bottom of the crushing teeth, avoiding cleaning dead corners when cleaning the crushing teeth.

[0014] Preferably, the lifting mechanism uses an electric telescopic rod, which is located inside the crushing teeth of the static jaw plate. The rotary connecting member is fixed to the movable end of the electric telescopic rod. The telescopic action of the electric telescopic rod drives the rotary connecting member and the cleaning plate to lift, thereby realizing the cleaning of the crushing teeth of the static jaw plate.

[0015] Preferably, the pushing mechanism uses an electric push rod, and the lifting member is installed at the movable end of the electric push rod. The pushing action of the electric push rod drives the lifting member and the rotary connecting member to move towards the movable jaw plate direction, so that the rotary connecting member completes a stroke from one end to the other end in the horizontal groove.

[0016] Preferably, the cleaning plate is hermetically connected to the dust-proof cover, and an inclined surface is provided at the top of the dust-proof cover and slopes downward. The sealed setting between the cleaning plate and the dust-proof cover can prevent powder from entering the dust-proof cover and falling on the cleaning plate when crushing the medicinal materials. Each time different medicinal materials are crushed, it can prevent the medicinal material powder from remaining on the cleaning plate and falling into the medicinal materials for the next crushing, affecting the use of the medicinal materials.

[0017] Preferably, the width of the cleaning plate is the same as the side width of the crushing teeth of the static jaw plate. When the cleaning plate lifts, it can completely clean the side of the crushing teeth, avoiding cleaning dead corners.

[0018] Preferably, air blowers are provided at the tops of the static jaw plate and the movable jaw plate, and the air blowers blow air towards the space between them. By providing the air blowers and arranging the air outlet of the air blowers between the static jaw plate and the crushing teeth of the movable jaw plate, the medicinal material powder on each crushing tooth can be blown off.

[0019] Adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0020] 1. After the medicinal materials are crushed, the first step is to use a blower to blow off the dust on the static jaw plate and the crushing teeth of the moving jaw plate to ensure the cleanliness of the crushing teeth and prepare for the next crushing work;

[0021] 2. The lifting member drives the rotating connecting member to move up and down, and then drives the cleaning plate to move up and down, and uses the cleaning plate to clean the tooth surface of the crushing teeth of the static jaw plate;

[0022] 3. A torsion spring is provided between the movable end of the cleaning plate and the rotating connecting member. When the rotating connecting member moves from the vertical groove to the horizontal groove, the cleaning plate will no longer be in close contact with the tooth surface of the crushing teeth of the static jaw plate. At this time, the torsion spring will reset and drive the cleaning plate to rotate. When the cleaning plate contacts the crushing teeth on the moving jaw plate, it can move from the tooth top to the tooth bottom of the crushing teeth, so as to comprehensively clean the crushing teeth on the moving jaw plate and ensure the cleanliness and crushing effect of the crushing teeth;

[0023] 4. By setting the rotating connecting member and the abutting member, when the rotating connecting member moves to one end of the horizontal groove, the abutting member makes the movable rod of the rotating connecting member rotate, and then makes the cleaning plate rotate to the same inclination angle as the moving jaw plate. When cleaning the moving jaw plate, the side of the cleaning plate will be in close contact with the tooth bottom of the moving jaw plate, so as to ensure that there is no dead angle in cleaning and improve the crushing efficiency and quality.

Specific embodiments

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0036] As Figures 1 - 9 shown, a traditional Chinese medicine crushing device includes a jaw crusher 1, a cleaning component 2, a pushing component 4 and an abutting component 3. The jaw crusher 1 has a fixed jaw plate 11 and a movable jaw plate 12. The cleaning component 2 is installed on the fixed jaw plate 11 of the jaw crusher 1. After the cleaning component 2 finishes cleaning the fixed jaw plate 11 of the jaw crusher 1, the cleaning component 2 is adjusted to an appropriate angle for cleaning the movable jaw plate 12 through the pushing component 4 and the abutting component 3, so as to clean the movable jaw plate 12 and avoid cleaning dead corners when cleaning the movable jaw plate 12.

[0037] During the process of traditional Chinese medicine crushing treatment, the crushing points of the jaw crusher 1 usually exist at the lower ends of the fixed jaw plate 11 and the movable jaw plate 12. The lower ends of the fixed jaw plate 11 and the movable jaw plate 12 will apply necessary crushing force to the medicinal materials to achieve effective crushing of the medicinal materials. During the crushing process, the residues of the medicinal materials often adhere to the lower ends of the fixed jaw plate 11 and the movable jaw plate 12. In order to maintain the efficient operation and cleanliness of the crusher, the cleaning component 2 is responsible for cleaning the lower ends of the fixed jaw plate 11 and the movable jaw plate 12. The cleaning component 2 includes a cleaning plate 21, a rotating connector 22 and a lifting component 23. Each fixed jaw plate 11 is equipped with a plurality of crushing teeth, and each crushing tooth has two sides. On each side, a cleaning plate 21 is installed, and these cleaning plates 21 are installed near the bottom of the fixed jaw plate 11. The rotating connector 22 is responsible for connecting the two cleaning plates 21 on the same crushing tooth. When cleaning the fixed jaw plate 11, the lifting component 23 is used to drive the rotating connector 22 to descend, and then the cleaning plate 21 descends. When the cleaning plate 21 descends, they will thoroughly clean the parts of the fixed jaw plate 11 where the medicinal material residues adhere.

[0038] As Figure 2As shown, taking the length of both the stationary jaw plate 11 and the moving jaw plate 12 as 30 cm as an example, during the process of the jaw crusher 1 crushing medicinal materials, the medicinal materials usually adhere to the area about 5 cm upward from the bottom of the stationary jaw plate 11 and the moving jaw plate 12. Therefore, the cleaning plate 21 is designed and installed at a position about 5 cm above the bottom of the stationary jaw plate 11. The cleaning plate 21 can move to the bottom of the stationary jaw plate 11 to scrape off the medicinal materials adhering there. The width of the cleaning plate 21 matches the side width of the crushing teeth, and rubber strips are installed on both sides. When the cleaning plate 21 is moved out of the dust-proof cover, its width can be appropriately increased to clean the tooth surface of the stationary jaw plate 11 more effectively. When the cleaning plate 21 re-enters the dust-proof cover, the rubber strips are squeezed, causing the overall width of the cleaning plate 21 to shrink, ensuring that the side of the crushing teeth can be thoroughly cleaned during the lifting process, thus avoiding cleaning blind spots.

[0039] During the design and use of the jaw crusher 1, considering the adhesion characteristics of the medicinal materials, the cleaning plate 21 is specially designed to improve the cleaning efficiency and operation convenience of the equipment. The stationary jaw plate 11 and the moving jaw plate 12, as the main working components of the crusher, both have a length of 30 cm, which provides sufficient contact area for crushing the medicinal materials. However, this also means that during the crushing process, the medicinal materials are likely to adhere to the area about 5 cm upward from the bottom of the jaw plates, which not only affects the crushing efficiency but also may cause abnormal wear of the equipment.

[0040] To solve this problem, the cleaning plate 21 is installed at a position about 5 cm above the bottom of the stationary jaw plate 11. The cleaning plate 21 can easily move to the bottom of the stationary jaw plate 11 to effectively scrape off the medicinal materials adhering to the bottom of the stationary jaw plate 11. In addition, the width of the cleaning plate 21 matches the side width of the crushing teeth, ensuring the comprehensiveness of the cleaning. The rubber strips installed on both sides not only increase the friction between the cleaning plate 21 and the crushing teeth but also allow its width to be appropriately increased when the cleaning plate 21 is moved out of the dust-proof cover to clean the tooth surface of the stationary jaw plate 11 more effectively.

[0041] When the cleaning plate 21 needs to re-enter the dust-proof cover, the rubber strips will be squeezed, causing the overall width of the cleaning plate 21 to shrink, thus ensuring that the side of the crushing teeth can be thoroughly cleaned during the lifting process. This design avoids the emergence of cleaning blind spots, guarantees the cleanliness and crushing efficiency of the crusher, and also extends the service life of the equipment. Through this innovative design, the jaw crusher 1 can be more efficient and hygienic when processing medicinal materials, meeting the high requirements of the modern pharmaceutical industry for equipment performance and cleanliness.

[0042] Such as Figure 1 and Figure 2As shown, a dust cover is provided on the periphery of the cleaning plate 21, the cleaning plate 21 is sealed and connected to the dust cover, and a downwardly inclined slope is provided on the top of the dust cover; when the medicinal materials are put into the jaw crusher 1, the medicinal materials may contact the cleaning plate 21, and some medicinal residues may fall on the cleaning plate 21. When the medicinal materials are crushed, the crushed medicinal material powder will also float on the cleaning plate 21. In order to avoid the medicinal materials from adhering to the cleaning plate 21, a dust cover is provided to avoid the presence of medicinal materials on the cleaning plate 21, and the top of the dust cover is provided to be an inclined surface inclined downward. When the medicinal materials are put between the static jaw plate 11 and the dynamic jaw plate 12, the medicinal materials are prevented from falling on the top of the dust cover. Even if dust falls on the top of the dust cover when the medicinal materials are crushed, when the medicinal materials are crushed, after the static jaw plate 11 and the dynamic jaw plate 12 complete the crushing of the medicinal materials, the dynamic jaw plate 12 continues to approach the static jaw plate 11 and contact each other. At this time, the vibration generated between the two will shake off the medicinal material powder that has fallen from the top of the dust cover, so as to prevent the medicinal material powder on the top of the dust cover from mixing with the new medicinal materials when the new medicinal materials are crushed.

[0043] In order to ensure that the medicinal powder does not enter the dust cover during the medicinal material crushing process, an opening is specially designed at the bottom of the dust cover. This opening is tightly connected to the cleaning plate 21 through a rubber pad to form an effective seal, thereby preventing the intrusion of powder. When crushing different types of medicinal materials, there may be residual medicinal powder on the cleaning plate 21, and these residual powders may have an adverse effect on the purity of the medicinal material crushing. In order to solve this problem, the dust cover adopts a segmented design. Its top is designed to be a structure with an inclination angle of 60 degrees. This structure helps when the medicinal material powder falls on the top of the dust cover, the wind blowing down from the top of the static jaw plate 11 effectively blows off the powder, thereby maintaining the purity of the medicinal material crushing. In addition, in order to withstand the huge pressure generated by the moving jaw plate 12 when it is close to the static jaw plate 11 to crush the medicinal material, the dust cover is specially made of hard stainless steel material. The choice of this material ensures that the dust cover will not deform when it is under pressure, thereby ensuring that the cleaning plate 21 can be smoothly lifted and lowered, ensuring the efficiency and stability of the entire crushing process.

[0044] like Figure 2 , Figure 7 and Figure 9As shown in the figure, a connecting shaft 211 is installed on the cleaning plate 21. The connecting shaft 211 is rotatably arranged on the movable part of the rotating connector 22. A torsion spring 212 is arranged between the connecting shaft 211 and the movable rod 222 of the rotating connector 22. Vertical grooves 13 are formed at the positions near the bottom of the crushing teeth of each fixed jaw plate 11, and transverse grooves 14 communicating with the vertical grooves 13 are formed on the crushing teeth of the fixed jaw plate 11. When the rotating connector 22 is located inside the vertical groove 13, one side of the cleaning plate 21 is closely attached to the tooth surface of the crushing teeth. The lifting member 23 drives the rotating connector 22 to slide in the vertical groove 13. At this time, the cleaning plate 21 cleans the crushing teeth of the fixed jaw plate 11. The rotating connector 22 transitions from the vertical groove 13 to the transverse groove 14 and slides to the other end in the transverse groove 14. At this time, the cleaning plate 21 is separated from the crushing teeth of the fixed jaw plate 11. Under the action of the torsion spring 212, the cleaning plate 21 is reset. At this time, the cleaning plate 21 is basically in a state perpendicular to the front view reference plane. When the moving jaw plate 12 approaches the fixed jaw plate 11, the cleaning plate 21 contacts the top of the crushing teeth of the moving jaw plate 12. Under the thrust of the moving jaw plate 12, the cleaning plate 21 gradually deflects towards the fixed jaw plate 11 and finally fits on the fixed jaw plate 11. At the same time, the cleaning plate 21 moves from the top of the crushing teeth of the moving jaw plate 12 towards the bottom of the crushing teeth of the moving jaw plate 12, thereby cleaning the crushing teeth of the moving jaw plate 12.

[0045] Specifically, the lifting member 23 is an electric telescopic rod, and the telescopic rod is cleverly embedded inside the crushing teeth of the fixed jaw plate 11. The rotating connector 22 is installed at the movable end of the electric telescopic rod. The telescopic function of the electric telescopic rod can drive the rotating connector 22 to perform a lifting action. In addition, the lifting member 23 also provides a hydraulic cylinder or a lead screw mechanism as an alternative. These solutions can also complete the lifting task of the rotating connector 22 through their specific operating methods.

[0046] In this design, the movable rod 222 on the rotating connector 22 is connected to the connecting shaft 211 by passing through the vertical groove 13. The function of the lifting member 23 is to drive the movable rod 222 on the rotating connector 22 to slide up and down in the vertical groove 13. It should be particularly noted that the vertical groove 13 is designed to extend downward from the bottom of the dust cover for a certain distance. When the rotating connector 22 slides to the bottom of the vertical groove 13, the cleaning plate 21 will move out of the dust cover for cleaning. In order to prevent medicinal material fragments from entering the inner side of the crushing teeth of the fixed jaw plate 11 from the vertical groove 13 during the crushing of medicinal materials, a shielding structure is specially designed at the bottom of the cleaning plate 21 to shield the part of the vertical groove 13 that protrudes downward from the dust cover. During the medicinal material crushing operation, a sealed connection is formed between the cleaning plate 21 and the dust cover, which can effectively prevent the dust generated during the crushing process from entering the dust cover and prevent the dust from falling on the cleaning plate 21.

[0047] During the working process of the jaw crusher 1, there is an included angle between the moving jaw plate 12 and the static jaw plate 11. However, when it is necessary to clean the crushing teeth on the moving jaw plate 12, a problem will be encountered. Since the lower right corner of the cleaning plate 21 used during cleaning cannot get closer to the moving jaw plate 12 after reaching the bottom of the crushing teeth, there will be some inaccessible dead areas on the crushing teeth of the moving jaw plate 12. To solve this problem, the inclination angle of the cleaning plate 21 can be adjusted to match the inclination angle of the moving jaw plate 12. When the moving jaw plate 12 approaches the static jaw plate 11, in this way, a comprehensive cleaning of the moving jaw plate 12 can be achieved, thus avoiding the problem of cleaning dead areas on the crushing teeth. Specifically, the included angle between the moving jaw plate 12 and the static jaw plate 11 is usually set between 15 degrees and 30 degrees. To ensure that the cleaning plate 21 can effectively clean the crushing teeth, its deflection angle needs to be consistent with the included angle between the moving jaw plate 12 and the static jaw plate 11, so as to ensure that the cleaning plate 21 can smoothly enter every corner of the crushing teeth and achieve thorough cleaning.

[0048] As Figures 1 - 8 shown, the rotating connector 22 includes a sleeve 221, and there are two movable rods 222, front and back, inside the sleeve 221. The movable rods 222 rotate freely within the sleeve 221. To ensure the stability of the movable rods 222 within the sleeve 221 and control their rotation, a torsion spring 223 is installed between each movable rod 222 and the sleeve 221. One end of the torsion spring 223 is fixedly connected to the bottom of the sleeve 221, while the other end is connected to the movable rod 222. Such a design can provide a resilience force for the movable rod 222. A connecting shaft 211 is provided on the movable rod 222 to allow it to perform a rotational movement. The stop member 3 is composed of a protrusion 31 and a stopper 32. The protrusion 31 is fixedly provided on the movable rod 222, while the stopper 32 is fixedly provided on one side of the transverse groove 14 near the tooth tip of the crushing teeth of the static jaw plate 11. When the rotating connector 22 moves from the bottom of the transverse groove 14 (i.e., the end close to the crushing teeth of the static jaw plate 11) towards the tooth tip direction, the protrusion 31 on the movable rod 222 will come into contact with the stopper 32. After the protrusion 31 contacts the stopper 32, it will push the movable rod 222 to rotate, thereby driving the cleaning plate 21 to rotate towards the moving jaw plate 12. When the moving jaw plate 12 approaches the static jaw plate 11, the cleaning plate 21 will slide into the tooth tip of the crushing teeth of the moving jaw plate 12 until it contacts the tooth bottom of the crushing teeth of the moving jaw plate 12. During this cleaning process, the torsion spring 212 will be twisted to ensure that the crushing teeth of the moving jaw plate 12 are completely cleaned.

[0049] As Figure 1 and Figure 7As shown, in the present invention, the pusher 4 is designed as an electric push rod, and the electric push rod drives the movement of the lifting member 23. The lifting member 23 is installed at the movable end of the electric push rod, and it can descend from the top of the vertical groove 13 until it enters the inside of the horizontal groove 14. During this process, the descending movement of the lifting member 23 is driven by the power provided by the electric push rod. At the same time, the movable end of the rotary connecting member 22 slides along the intersection of the horizontal groove 14 and the vertical groove 13 to the other side. In the initial position, that is, when the rotary connecting member 22 is in the vertical groove 13, the torsion spring 212 is twisted so that the cleaning plate 21 fits in the twisted state of the torsion spring 212. Under the action of the torsion spring 212, the cleaning plate 21 fits on the side of the crushing teeth of the stationary jaw plate 11. When the rotary connecting member 22 moves in the horizontal groove 14, the torsion spring 212 resets and causes the cleaning plate 21 to deflect in a direction away from the side of the crushing teeth of the stationary jaw plate 11. When the protrusion 31 contacts the stopper 32, the movable rod 222 rotates accordingly, and then drives the cleaning plate 21 to deflect towards the movable jaw plate 12. The deflection angle is precisely designed. When the movable rod 222 moves to the end of the horizontal groove 14, the degree of the deflection angle of the cleaning plate 21 is exactly the same as the degree of the included angle between the movable jaw plate 12 and the stationary jaw plate 11. During the cleaning of the movable jaw plate 12, when the movable jaw plate 12 approaches the stationary jaw plate 11, the cleaning plate 21 will penetrate to the bottom of the crushing teeth, so as to ensure the comprehensive cleaning of the crushing teeth of the movable jaw plate 12 and avoid the occurrence of cleaning blind spots. When the movable jaw plate 12 moves away from the stationary jaw plate 11, the cleaning plate 21 can be reset under the combined action of the pusher 4 and the rotary connecting member 22 and re-enter the dust-proof cover. When performing crushing operations on other medicinal materials, users can directly put the new medicinal materials into the jaw crusher 1 for crushing treatment, which is simple and efficient in operation.

[0050] In the process of implementing the present invention, it should be particularly noted that when the pushing member 4 drives the rotating connecting member 22 to move from one end close to the tooth tip of the crushing teeth of the static jaw plate 11 to the other end close to the tooth bottom of the crushing teeth of the static jaw plate 11 along the transverse groove 14, the pushing member 4 needs to move quickly. During this process, the protrusion 31 and the stopper 32 quickly disengage from contact. This is because under the action of the torsion spring 223, the cleaning plate 21 can quickly reset. To further optimize the cleaning effect, a knocking assembly can be provided between the sleeve 221 and the movable rod 222. The knocking assembly includes a blocking platform provided in the sleeve 221 and a knocking block provided on the movable rod 222. After the torsion spring 223 completes the reset, the knocking block will knock on the blocking platform, and at this time, the movable rod 222 will vibrate. This vibration will be transmitted to the cleaning plate 21, so that when the cleaning plate 21 cleans the static jaw plate 11 and the movable jaw plate 12, the medicinal material powder adhered to the cleaning plate 21 can be shaken off, and at the same time, it can assist in shaking off the medicinal materials that may not have been scraped off on the static jaw plate 11. The material of the cleaning plate 21 can be specifically selected as anti-sticking materials such as polytetrafluoroethylene. In addition, in order to reduce the sticking of medicinal materials, the efficiency and effect of the entire crushing and cleaning process can be improved.

[0051] In other embodiments, the pushing member 4 can also adopt a linear motor or other types of linear motion devices. Through the action of these linear motion devices, the lifting member 23 is driven to perform corresponding linear motion. Subsequently, the lifting member 23 will further drive the rotating connecting member 22 so that it can smoothly move from one end to the other end along the transverse groove 14.

[0052] In the design of the jaw crusher 1, air blowers are specially configured at the tops of the static jaw plate 11 and the movable jaw plate 12. The purpose of these air blowers is to blow air towards the space between the two (although not shown in the figure). After the jaw crusher 1 completes the crushing work on the medicinal materials, the air blowers will start to blow air into the gap between the static jaw plate 11 and the movable jaw plate 12 to blow off the medicinal material powder that is not adhered to the static jaw plate 11 and the movable jaw plate 12. For the tiny dust that cannot be blown off by the air blowers, the above-mentioned cleaning solution is adopted for thorough cleaning.

[0053] In addition, vertical air outlets are carefully arranged between each crushing tooth of the static jaw plate 11 and the movable jaw plate 12. After the crushing process is completed, these air outlets can effectively perform preliminary cleaning on the medicinal material powder on each crushing tooth. In this way, after the cleaned medicinal material powder falls, we then perform further cleaning on the medicinal materials adhered to the static jaw plate 11 and the movable jaw plate 12 through the operation methods described above to ensure the cleanliness of the entire crushing area.

[0054] Working principle:

[0055] During the process of medicinal material processing, when the medicinal materials are fed into the crusher for crushing, the lifting member 23 will be activated to drive the cleaning plate 21 to move up and down. The purpose of this movement is to clean the possible residual medicinal material fragments on the stationary jaw plate 11. To ensure that the crushed medicinal material powder does not adhere to the cleaning plate 21, the cleaning plate 21 is placed inside the dust-proof cover during the medicinal material crushing process, which can effectively prevent the retention of the powder. After completing the cleaning work of the stationary jaw plate 11, the pushing member 4 will come into play and push the rotating connecting member 22 to slide along the transverse groove 14 to the other end. During this sliding process, the cleaning plate 21 will disengage from the tooth surface of the crushing teeth of the stationary jaw plate 11. The torsion spring 212 functions to deflect the cleaning plate 21, thereby changing its position. When the moving jaw plate 12 approaches, the cleaning plate 21 will contact the tooth tips of its crushing teeth and start to clean the moving jaw plate 12. When the protrusion 31 on the rotating connecting member 22 contacts the stop block 32 provided on one side of the transverse groove 14, the movable end of the rotating connecting member 22 will start to rotate, thereby guiding the cleaning plate 21 to rotate towards the direction of the moving jaw plate 12. This design ensures that during the process of cleaning the moving jaw plate 12, the cleaning plate 21 can cover every corner of the moving jaw plate 12, thus avoiding the occurrence of cleaning dead corners and ensuring the thoroughness of the cleaning work.

[0056] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
