Technical Field
[0001] This invention belongs to the field of crushing equipment technology, specifically a crushing device for raw materials of Centella asiatica used in medicine. Background Technology
[0002] Centella asiatica is a plant belonging to the Santalaceae family and the Centella genus. It is a perennial, delicate herb, 15-40 cm tall, with the entire plant somewhat covered in a white powder and hairless; the stems are slender, clustered, sparsely branched above the base, ascending obliquely, and have longitudinal grooves. Centella asiatica contains flavonoid glycosides, mannitol, and other components. It is pungent, astringent, and cool in nature, and enters the lung and kidney meridians. It has the effects of clearing heat and detoxifying, and relieving summer heat. Usually, dried Centella asiatica is crushed into small pieces for later use in medicine.
[0003] The existing crushing device for medicinal raw materials of Centella asiatica involves feeding dried Centella asiatica into a crushing drum for stirring and crushing, and then collecting the crushed Centella asiatica product. In practice, during the discharge process, the crushed material is extruded by a spiral feeding blade. The dried Centella asiatica mainly becomes crushed material and powder. Currently, a large amount of crushed material is discharged from the outlet, while the lighter powder is scattered in the environment, causing a large amount of dust at the outlet. Some of the powder cannot be effectively collected. Dust collector bags are used to suck up dust at the discharge end and collect the powder. However, due to the limited size of the equipment, the area that can be covered by the dust collector bags is limited. During the dust collection process, the surface of the dust collector bags is easily clogged after sufficient collection, and the actual replacement frequency is high. It requires machine shutdown for replacement and frequent disassembly and collection, which is cumbersome to use and the actual dust removal effect is not good. Some Centella asiatica powder is still scattered in the environment.
[0004] Furthermore, existing crushing devices for medicinal raw materials of Centella asiatica are affected by factors such as the crushing effect and the degree of dryness of the Centella asiatica when discharging the crushed material at the rear end of the crushing cylinder. Some Centella asiatica is not crushed sufficiently, and the crushed material of a certain length and volume is prone to causing blockage at the discharge end, affecting the discharge rate of crushed material. Moreover, when it is necessary to clear the blockage, the machine needs to be stopped and the blockage needs to be cleared manually after the machine is stopped, which greatly delays the crushing progress, reduces the actual production efficiency, and has poor performance. Summary of the Invention
[0005] The purpose of this invention is to provide a device for crushing raw materials of Centella asiatica for medicinal use, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a crushing device for medicinal raw materials of *Centella asiatica*, comprising a base, a crushing cylinder on the top surface of the base, a rotating mechanism fixedly installed inside the crushing cylinder, a connecting plate fixedly connected to the inner surface of the left end of the crushing cylinder, a collar fixedly connected to the end face of the connecting plate, the inner surface of the collar being movably sleeved with the crushing cylinder, an mounting sleeve fixedly sleeved to the outer surface of the left end of the crushing cylinder, a sleeve fixedly connected to the left end of the crushing cylinder, a filtering mechanism fixedly connected to the end face of the sleeve, and the filtering mechanism and the sleeve... A dust removal bag is fitted on the outer surface of the mounting sleeve. A clamping mechanism is fixedly connected to the outer surface of the mounting sleeve. A curved tube is fixedly connected to the top of the clamping mechanism. An adjusting mechanism is fixedly connected to the end face of the curved tube. An air pump is provided on the top surface of the crushing cylinder. A connecting pipe is fixedly connected between the air pump and the adjusting mechanism. A distribution sleeve is fixedly fitted on the outer surface of the crushing cylinder. An air inlet pipe is fixedly connected between the distribution sleeve and the adjusting mechanism. An air guide pipe is fixedly connected to the outer surface of the distribution sleeve. The inner end of the air guide pipe is fixedly fitted to the side of the crushing cylinder. An agitation mechanism is provided inside the air guide pipe.
[0007] First embodiment: as follows Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, before crushing, the dust collection bag is fitted onto the outside of the filter mechanism, and one end of the dust collection bag is pulled along the sleeve, so that one end of the dust collection bag overlaps and stacks between the sleeve and the mounting sleeve. The air pump is started, so that the air pump introduces gas into the regulating mechanism through the connecting pipe, and the introduced air enters the curved pipe through the regulating mechanism. As the gas enters the clamping mechanism through the curved pipe, the air in the clamping mechanism pushes the mounting plate to move, so that the spring is stretched and the bottom surface of the damping pad presses against the outside of the stacked dust collection bag. The threaded rod in the regulating mechanism is rotated outward, so that the gas introduced by the air pump flows into the air inlet pipe through the regulating mechanism, and the gas in the air inlet pipe flows into the air guide pipe through the distribution sleeve. The dried centella asiatica is put into the feeding box, and the power mechanism is started, so that the rotating mechanism rotates, so that the rotating rod drives the feeding blade to rotate and feeds the centella asiatica raw material to the stirring blade for crushing. The crushed centella asiatica is pushed to the crushing roller to complete the crushing. The crushed materials continue to be pushed to the left end of the crushing cylinder. The outward-extending materials are then propelled by air blown out at an angle from the duct, causing them to be rapidly ejected. After being ejected, the materials are stored inside the dust collector bag. Clean air is blown out through the outside of the dust collector bag. As the inner surface of the dust collector bag fills with powder and materials, it loses its ventilation capacity. Continued airflow causes the internal airflow to push the dust collector bag outwards. Laterally stretched, the stacked dust collection bags overcome the pressure of the damping pads and extend outwards. The clean dust collection bags move to one side of the filtration mechanism to continue collecting and filtering powder and holding crushed materials. As material is continuously discharged and air is circulated, the volume of the dust collection bags gradually increases. When the insertion end of the dust collection bag is fully extended and removed from the pressure sensor, the machine stops. The dust collection bags filled with crushed and powdered materials can be removed and transferred. Replace and attach new dust collection bags to collect and filter the crushed and powdered materials of Centella asiatica.
[0008] First, an installation sleeve is fixedly attached to the outer surface of the left end of the crushing cylinder, and a sleeve is fixedly connected to the left end of the crushing cylinder. A dust collection bag is then fitted between the sleeve and the installation sleeve. The dust collection bag is pushed so that the longer end of the dust collection bag is stacked between the sleeve and the installation sleeve, and the dust collection bag is fitted outside the filter mechanism. Using the pneumatic power provided by the air pump, part of the pneumatic power applies pressure to the fitted dust collection bag from the side, and the other part of the pneumatic power is introduced into the discharge end of the crushing cylinder. The pneumatic power blows the powder and fragments into the dust collection bag, and the dust collection bag filters and collects the powder and fragments of the centella asiatica. At the same time, the pneumatic power pushes the dust collection bag to gradually unfold after it is blocked on the inner surface of the dust collection bag, and continues to filter and collect the powder and fragments. This effectively avoids the automatic handling of dust collection bag blockage, and avoids the limited area of the dust collection bag from becoming blocked when collecting and filtering powder, thus avoiding machine shutdown and replacement. This ensures continuous collection and filtration of powder, reduces downtime for cleaning, and improves the actual efficiency of powder collection and filtration.
[0009] Furthermore, by stacking long dust collection bags between the installation sleeve and the casing, and coordinating with air blown from inside the crushing cylinder, the pneumatic power is used to increase the discharge rate of the material in the crushing cylinder while simultaneously blowing the crushed fragments and powder into the dust collection bags. This achieves simultaneous collection of powder and fragments, effectively preventing dust from flying at the discharge end, improving the collection effect of crushed *Centella asiatica*, and enabling the recycling of *Centella asiatica* powder. This increases the yield of crushed *Centella asiatica* products. Moreover, as the material is blown into the dust collection bag by the pneumatic power, the dust collection bag gradually expands, preventing the direct introduction of powder from clogging the entire inner surface of the dust collection bag. By gradually expanding, the filtration time of the dust collection bag is extended, storing a large amount of powder in the middle space of the dust collection bag, preventing light powder from accumulating on the inner surface of the dust collection bag, improving the collection and storage effect, and resulting in good performance.
[0010] Preferably, the outer surface of the mounting sleeve has a side groove and a first groove. The outer end of the first groove is connected to the clamping mechanism. A pressure sensor is fixedly sleeved on the bottom surface of the outer surface of the mounting sleeve. The pressure sensor senses the dust collection bag in the sleeve and ensures that the machine stops when the dust collection bag is full.
[0011] Preferably, the clamping mechanism includes a fixed frame, a spring, a mounting plate, a damping pad, and a limiting rod. The limiting rod and the spring are both fixedly connected to the inside of the fixed frame. The damping pad is fixedly installed on the bottom surface of the mounting plate, and the top surface of the mounting plate is fixedly connected to the spring. The dimensions of the mounting plate and the damping pad are both smaller than the dimensions of the first slot. By introducing some air into the clamping mechanism, the introduced air pushes the damping pad to press down on the dust collection bag exiting the stack, preventing the dust collection bag from unfolding before it is fully filled with material, thus improving the collection and storage effect, slowing down the unfolding speed, and achieving gradual unfolding and gradual filtration and collection.
[0012] Preferably, the filtration mechanism includes a fixed ring, filter holes, and a limiting plate. The filter holes are distributed in a ring on the outer surface of the fixed ring, and the limiting plate is fixedly connected to the outer surface of the fixed ring. The filtration mechanism allows debris to be located inside the filtration mechanism, while powder enters the inner side of the dust collector bag through the filter holes, achieving collection and filtration. As the inner surface of the unfolded dust collector bag is blocked by powder, the inside of the dust collector bag is sealed. The continuously supplied air pushes the dust collector bag to move, thereby further opening the dust collector bag, allowing the newly extended dust collector bag to continue to filter and collect powder outside the filtration mechanism. Under the internal sealing condition, the supplied powder and debris are mixed in the middle of the internal space of the dust collector bag.
[0013] Preferably, the adjustment mechanism includes an adjustment seat, an inner cavity, a first hole, a second hole, a threaded rod, and a movable plug. The movable plug is movably sleeved inside the inner cavity, and the threaded rod is threadedly sleeved on the side of the adjustment seat. The inner end of the threaded rod is fixedly connected to the movable plug. The first hole and the second hole are respectively opened on the top surface and the right side surface of the adjustment seat.
[0014] Preferably, both the first hole and the second hole are connected to the inner cavity, and the inner diameters of both the first hole and the second hole are smaller than the diameter of the movable plug. The upper end of the first hole is fixedly connected to a connecting pipe, and the outer end of the second hole is fixedly connected to the air inlet pipe. By rotating the threaded rod, the movable plug is moved laterally. By changing the position of the movable plug and the first hole, the direction of gas flow can be controlled. When the movable plug is located on the right side of the lower end of the first hole, the movable plug seals the second hole, and the gas is introduced into the curved pipe to achieve clamping. When the threaded rod is rotated outward, the movable plug is moved to the left side of the first hole. At this time, the gas introduced is blocked by the movable plug in the inner cavity, so that the air is introduced into the air inlet pipe through the open second hole.
[0015] Preferably, the distribution sleeve has a distribution groove inside, and there are two air guide pipes. The two air guide pipes are symmetrically distributed on both sides of the crushing cylinder. The two air guide pipes are evenly connected to the distribution groove. Both sets of air guide pipes are inclined and inserted into the inside of the crushing cylinder. The air outlet of the inner end of the air guide pipe is inclined towards the left end of the crushing cylinder. The air force is used to blow the conveyed crushed material and powder out, thereby improving the discharge speed and effect.
[0016] Preferably, the agitation mechanism includes a mounting rod, a disc, an annular groove, blades, a retaining ring, an agitating rod, and an agitating plate. The mounting rod is fixedly connected to the inner surface of the air guide pipe, the disc is fixedly connected to the side of the mounting rod, the blades are movably sleeved on the outer surface of the disc, the retaining ring is fixedly sleeved on the inner side of the blades, the annular groove is formed on the outer surface of the disc, the outer surface of the retaining ring is movably sleeved with the annular groove, the end face of the agitating rod is fixedly connected to the end face of the blades, and the agitating plate is fixedly connected to the outer surface of the agitating rod. By utilizing the movable sleeve of the retaining ring and the annular groove, the blades can rotate stably and freely, thereby driving the rotation of the agitating rod under the blowing of air.
[0017] Preferably, the rotating mechanism includes a rotating rod, a feeding blade, a stirring blade, and a crushing roller, wherein the feeding blade, the stirring blade, and the crushing roller are all fixedly sleeved on the outer surface of the rotating rod.
[0018] Preferably, the top surface of the base is provided with a power mechanism, the output shaft of the power mechanism is fixedly connected to the rotating mechanism, and the outer surface of the crushing cylinder is fixedly connected to the feed box. By using the power mechanism to drive the rotating mechanism to rotate, the conveying, crushing and discharge of the centella asiatica can be realized.
[0019] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, when collecting and discharging materials, the air pump is started, which introduces air into the regulating mechanism through the connecting pipe. The regulating mechanism then introduces the air into the distribution sleeve through the air inlet pipe. As the air flows through the distribution sleeve into the air guide pipe, the high-speed airflow drives the blades in the agitator to rotate at high speed. This causes the blades to drive the agitator rod on the side to rotate. The agitator rod, which is tilted inside the left end of the crushing cylinder, drives the agitator plate to rotate, thus agitating and opening up the crushed material blocking the outlet, allowing the left end of the crushing cylinder to discharge smoothly.
[0020] Firstly, by adding an agitation mechanism inside the air duct, when high-speed air is introduced by the air pump, the high-speed air flowing in the air duct drives the movable sleeve blades to rotate. The rotation of the blades drives the agitator rod, which is tilted inside the left end of the crushing cylinder, to rotate, thereby agitating the material at the discharge port. Combined with the tilted high-speed air, the mechanical agitation and outward pneumatic force are used to automatically handle blockages, effectively preventing blockages at the left end of the crushing cylinder, avoiding downtime for maintenance, ensuring continuous and stable material output, greatly increasing actual production efficiency, and achieving good results.
[0021] The beneficial effects of this invention are as follows:
[0022] 1. This invention involves fixing an installation sleeve to the outer surface of the left end of a crushing cylinder and connecting a tube to the left end of the crushing cylinder. A dust collection bag is then fitted between the tube and the installation sleeve. The dust collection bag is pushed, causing the longer end of the bag to stack between the tube and the installation sleeve, thus covering the outside of the filtration mechanism. Using pneumatic power provided by an air pump, part of the pneumatic force applies pressure to the fitted dust collection bag from the side, while another part is introduced to the discharge end of the crushing cylinder. This pneumatic force blows the powder and fragments into the dust collection bag, allowing for the filtration and collection of *Centella asiatica* powder and fragments. Simultaneously, the pneumatic force, after causing blockage on the inner surface of the dust collection bag, pushes the bag to gradually unfold, continuously filtering and collecting the powder and fragments. This effectively avoids the need for automatic dust bag clogging, preventing the limited area of the dust collection bag from clogging and requiring machine shutdown for replacement. It ensures continuous powder collection and filtration, reduces downtime for cleaning, and thus improves the actual efficiency of powder collection and filtration.
[0023] 2. This invention utilizes pneumatic power to increase the material discharge rate from the crushing cylinder by stacking a long dust collection bag between the mounting sleeve and the sleeve, and coordinating with air blown from inside the crushing cylinder. Simultaneously, it blows the crushed fragments and powder into the dust collection bag, achieving simultaneous collection of both materials. This effectively prevents dust from flying at the discharge end, improves the collection effect of crushed *Centella asiatica*, and enables the recycling of *Centella asiatica* powder, thereby increasing the yield of crushed *Centella asiatica*. Furthermore, the dust collection bag gradually expands as it is filled with material through pneumatic blowing, preventing direct powder from clogging the inner surface of the bag. This gradual expansion extends the filtration time of the dust collection bag, storing a large amount of powder in the central space, preventing lightweight powder from accumulating on the inner surface of the bag, thus improving collection and storage efficiency and resulting in good performance.
[0024] 3. This invention adds an agitation mechanism inside the air duct. When high-speed air is introduced by an air pump, the high-speed air flowing in the air duct drives the movable blades to rotate. The rotation of the blades drives the agitator rod, which is tilted inside the left end of the crushing cylinder, to rotate, thereby agitating the material at the discharge port. Combined with the high-speed air introduced at an angle, the mechanical agitation and outward pneumatic force automatically handle blockages, effectively preventing blockages at the left end of the crushing cylinder, avoiding downtime for maintenance, ensuring continuous and stable material output, greatly increasing actual production efficiency, and achieving good results.

Detailed Implementation
[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] like Figures 1 to 8 As shown in the embodiment of the present invention, a crushing device for medicinal raw materials of *Centella asiatica* includes a base 1, a crushing cylinder 3 on the top surface of the base 1, a rotating mechanism 5 fixedly installed inside the crushing cylinder 3, a connecting plate 6 fixedly connected to the inner surface of the left end of the crushing cylinder 3, a collar 7 fixedly connected to the end face of the connecting plate 6, the inner surface of the collar 7 movably sleeved with the crushing cylinder 3, an installation sleeve 8 fixedly sleeved to the outer surface of the left end of the crushing cylinder 3, a sleeve 9 fixedly connected to the left end of the crushing cylinder 3, a filtering mechanism 10 fixedly connected to the end face of the sleeve 9, and a dust removal bag 11 sleeved on the outer surface of the filtering mechanism 10 and the sleeve 9. A clamping mechanism 13 is fixedly connected to the outer surface of sleeve 8. A curved pipe 14 is fixedly connected to the top of clamping mechanism 13. An adjusting mechanism 15 is fixedly connected to the end face of curved pipe 14. An air pump 16 is provided on the top surface of crushing cylinder 3. A connecting pipe 17 is fixedly connected between air pump 16 and adjusting mechanism 15. A distribution sleeve 18 is fixedly sleeved on the outer surface of crushing cylinder 3. An air inlet pipe 19 is fixedly connected between distribution sleeve 18 and adjusting mechanism 15. An air guide pipe 20 is fixedly connected to the outer surface of distribution sleeve 18. The inner end of air guide pipe 20 is fixedly sleeved on the side of crushing cylinder 3. An agitation mechanism 21 is provided inside air guide pipe 20.
[0036] First embodiment: as follows Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, before crushing, the dust bag 11 is fitted onto the outside of the filter mechanism 10, and one end of the dust bag 11 is pulled along the sleeve 9 so that one end of the dust bag 11 overlaps and is fitted between the sleeve 9 and the mounting sleeve 8. The air pump 16 is started, so that the air pump 16 introduces gas into the regulating mechanism 15 through the connecting pipe 17, and the introduced air enters the curved pipe 14 through the regulating mechanism 15. As the gas enters the clamping mechanism 13 through the curved pipe 14, the air in the clamping mechanism 13 pushes the mounting plate 133 to move, causing the spring 132 to stretch. Simultaneously, the bottom surface of the damping pad 134 presses against the outer side of the dust collection bag 11 of the stack sleeve, and the threaded rod 155 in the adjusting mechanism 15 is rotated outward, so that the gas introduced by the air pump 16 flows into the air inlet pipe 19 through the adjusting mechanism 15, and the gas introduced into the air inlet pipe 19 flows to the air guide pipe 20 through the distribution sleeve 18. The dried centella asiatica is put into the feeding box 4, the power mechanism 2 is started, so that the rotating mechanism 5 rotates, so that the rotating rod 51 drives the feeding blade 52 to rotate and feed the centella asiatica raw material to the stirring blade 53 for crushing. The crushed centella asiatica The material is pushed to the crushing roller 54 to complete the crushing. The crushed material and powder continue to be pushed to the left end of the crushing cylinder 3. The crushed material and powder are squeezed out and then blown out by the air blown out at an angle through the air guide pipe 20, causing the material and powder to be quickly ejected. After being ejected, the material and powder are stored inside the dust collector bag 11. Clean air is blown out through the outside of the dust collector bag 11. As the inner surface of the dust collector bag 11 is filled with powder and crushed material, the dust collector bag 11 loses its ventilation capacity. With the continued introduction of air, the wind inside the dust collector bag 11 pushes the dust collector bag 11 to move outward. As the dust collection bag 11 is stretched outward, the stacked dust collection bag 11 overcomes the pressure of the damping pad 134 and extends outward. The clean dust collection bag 11 moves to one side of the filter mechanism 10 to continue collecting and filtering powder and holding crushed material. With continuous discharge and ventilation, the volume of the dust collection bag 11 gradually increases. When the insertion end of the dust collection bag 11 is fully unfolded and removed from the pressure sensor 24, the machine stops. The dust collection bag filled with crushed material and powder is removed and transferred. A new dust collection bag 11 is then fitted and used to collect and filter the crushed and powdered material of Centella asiatica.
[0037] First, by fixing the mounting sleeve 8 to the outer surface of the left end of the crushing cylinder 3, and fixing the sleeve 9 to the left end of the crushing cylinder 3, a dust collector bag 11 is fitted between the sleeve 9 and the mounting sleeve 8. The dust collector bag 11 is then pushed, causing the longer end of the dust collector bag 11 to stack between the sleeve 9 and the mounting sleeve 8, thus fitting the dust collector bag 11 onto the outside of the filter mechanism 10. Using the pneumatic force provided by the air pump 16, part of the pneumatic force applies pressure to the fitted dust collector bag 11 from the side, while another part of the pneumatic force is introduced into the discharge end of the crushing cylinder 3. Pneumatic power is used to blow powder and debris into the dust collection bag 11, which filters and collects the powder and debris of the *Centella asiatica*. Simultaneously, the pneumatic power pushes the dust collection bag 11 to gradually expand after it becomes clogged on the inner surface, continuously filtering and collecting the powder and debris. This effectively avoids the need for automatic handling of clogged dust collection bags 11, preventing the limited area of the dust collection bag 11 from becoming clogged and requiring machine shutdown for replacement. This ensures continuous collection and filtration of powder, reduces downtime for cleaning, and thus improves the actual efficiency of powder collection and filtration.
[0038] Furthermore, by stacking the long dust collection bag 11 between the mounting sleeve 8 and the sleeve 9, and cooperating with the air blown from inside the crushing cylinder, the pneumatic power is used to increase the discharge rate of the material in the crushing cylinder 3, while simultaneously blowing the crushed fragments and powder into the dust collection bag 11, achieving simultaneous collection of powder and fragments. This effectively prevents dust from flying at the discharge end, improves the collection effect of the crushed *Centella asiatica*, and enables the recycling of *Centella asiatica* powder, thereby increasing the yield of the crushed *Centella asiatica* product. Moreover, as the material is blown into the dust collection bag 11 by the pneumatic power, the dust collection bag 11 gradually expands, preventing the direct introduction of powder from completely clogging the inner surface of the dust collection bag 11. By gradually expanding, the filtration time of the dust collection bag 11 is extended, storing a large amount of powder in the middle space of the dust collection bag 11, preventing the accumulation of light powder on the inner surface of the dust collection bag 11, improving the collection and storage effect, and resulting in good performance.
[0039] The outer surface of the mounting sleeve 8 is provided with a side groove 12 and a first groove 23. The outer end of the first groove 23 is connected to the clamping mechanism 13. A pressure sensor 24 is fixedly sleeved on the bottom surface of the outer surface of the mounting sleeve 8. The pressure sensor 24 senses the dust removal bag 11 of the sleeve and ensures that the machine stops when the dust removal bag 11 is full.
[0040] The clamping mechanism 13 includes a fixed frame 131, a spring 132, a mounting plate 133, a damping pad 134, and a limiting rod 135. The limiting rod 135 and the spring 132 are both fixedly connected to the inside of the fixed frame 131. The damping pad 134 is fixedly installed on the bottom surface of the mounting plate 133, and the top surface of the mounting plate 133 is fixedly connected to the spring 132. The dimensions of the mounting plate 133 and the damping pad 134 are both smaller than the dimensions of the first slot 23. By introducing some air into the clamping mechanism 13, the introduced air pushes the damping pad 134 to press down the dust collection bag 11 exiting the stack, preventing the dust collection bag 11 from unfolding before it is fully filled with material, thus improving the collection and storage effect, slowing down the unfolding speed, and achieving gradual unfolding and gradual filtration and collection.
[0041] The filtration mechanism 10 includes a fixed ring 101, filter holes 102, and a limiting plate 103. The filter holes 102 are distributed in a ring on the outer surface of the fixed ring 101, and the limiting plate 103 is fixedly connected to the outer surface of the fixed ring 101. The filtration mechanism 10 allows debris to be located inside the filtration mechanism 10, while powder enters the inner side of the dust collection bag 11 through the filter holes 102 for collection and filtration. As the inner surface of the unfolded dust collection bag 11 is blocked by powder, the inside of the dust collection bag 11 is sealed. The continuously supplied air pushes the dust collection bag 11 to move, thereby further opening the dust collection bag 11. The newly extended dust collection bag 11 continues to filter and collect powder outside the filtration mechanism 10. Under the internal sealing condition, the supplied powder and debris are mixed in the middle of the internal space of the dust collection bag 11.
[0042] The adjustment mechanism 15 includes an adjustment seat 151, an inner cavity 152, a first hole 153, a second hole 154, a threaded rod 155, and a movable plug 156. The movable plug 156 is movably sleeved inside the inner cavity 152. The threaded rod 155 is threadedly sleeved on the side of the adjustment seat 151. The inner end of the threaded rod 155 is fixedly connected to the movable plug 156. The first hole 153 and the second hole 154 are respectively opened on the top surface and the right side surface of the adjustment seat 151.
[0043] Both No. 1 hole 153 and No. 2 hole 154 are connected to the inner cavity 152. The inner diameters of both No. 1 hole 153 and No. 2 hole 154 are smaller than the diameter of the movable plug 156. The upper end of No. 1 hole 153 is fixedly connected to the connecting pipe 17, and the outer end of No. 2 hole 154 is fixedly connected to the air inlet pipe 19. By rotating the threaded rod 155, the movable plug 156 is moved laterally. By changing the position of the movable plug 156 and No. 1 hole 153, the direction of gas flow can be controlled. When the movable plug 156 is located on the right side of the lower end of No. 1 hole 153, the movable plug 156 seals the No. 2 hole 154, and the gas is introduced into the curved pipe 14 to achieve clamping. When the threaded rod 155 is rotated outward, the movable plug 156 is moved to the left side of No. 1 hole 153. At this time, the gas introduced is blocked by the movable plug 156 in the inner cavity 152, so that the air is introduced into the air inlet pipe 19 through the open No. 2 hole 154.
[0044] The distribution sleeve 18 has a distribution groove 22 inside, and there are two air guide pipes 20. The two air guide pipes 20 are symmetrically distributed on both sides of the crushing cylinder 3. The two air guide pipes 20 are evenly distributed and connected to the distribution groove 22. Both sets of air guide pipes 20 are inclined and inserted into the inside of the crushing cylinder 3. The air outlet of the inner end of the air guide pipe 20 is inclined towards the left end of the crushing cylinder 3. The air force is used to blow the conveyed crushed material and powder out, thereby improving the discharge speed and effect.
[0045] The agitation mechanism 21 includes a mounting rod 211, a disc 212, an annular groove 213, a blade 214, a retaining ring 215, an agitation rod 216, and an agitation plate 217. The mounting rod 211 is fixedly connected to the inner surface of the air duct 20. The disc 212 is fixedly connected to the side of the mounting rod 211. The blade 214 is movably sleeved on the outer surface of the disc 212. The retaining ring 215 is fixedly sleeved on the inner side of the blade 214. The annular groove 213 is formed on the outer surface of the disc 212. The outer surface of the retaining ring 215 is movably sleeved with the annular groove 213. The end face of the agitation rod 216 is fixedly connected to the end face of the blade 214. The agitation plate 217 is fixedly connected to the outer surface of the agitation rod 216. By utilizing the movable sleeve of the retaining ring 215 and the annular groove 213, the blade 214 can rotate freely and stably, thereby driving the rotation of the agitation rod 216 under the blowing of air.
[0046] The rotating mechanism 5 includes a rotating rod 51, a feeding blade 52, an agitating blade 53, and a crushing roller 54. The feeding blade 52, the agitating blade 53, and the crushing roller 54 are all fixedly sleeved on the outer surface of the rotating rod 51.
[0047] The base 1 has a power mechanism 2 on its top surface. The output shaft of the power mechanism 2 is fixedly connected to the rotating mechanism 5. The outer surface of the crushing cylinder 3 is fixedly connected to the feed box 4. By using the power mechanism 2 to drive the rotating mechanism 5 to rotate, the conveying, crushing and discharge of the centella asiatica can be realized.
[0048] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, when collecting and discharging materials, the air pump 16 is started, which introduces air into the regulating mechanism 15 through the connecting pipe 17. The regulating mechanism 15 then introduces the air into the distribution sleeve 18 through the air inlet pipe 19. As the air flows through the distribution sleeve 18 into the air guide pipe 20, the high-speed airflow drives the blades 214 in the stirring mechanism 21 to rotate at high speed. This causes the blades 214 to drive the stirring rod 216 on the side to rotate. The stirring rod 216, which is tilted inside the left end of the crushing cylinder 3, drives the stirring plate 217 to rotate, so that the crushed material blocking the outlet is stirred and opened, and the material discharge from the left end of the crushing cylinder 3 is smooth.
[0049] First, by adding an agitation mechanism 21 inside the air duct 20, when high-speed air is introduced by the air pump 16, the high-speed air flowing in the air duct 20 drives the movable sleeve blade 214 to rotate. The rotation of the blade 214 drives the agitator 216, which is tilted inside the left end of the crushing cylinder 3, to rotate, thereby agitating the discharge port. Combined with the high-speed air introduced at an angle, the mechanical agitation and outward pneumatic force are used to automatically handle blockages, effectively preventing blockages at the left end of the crushing cylinder 3, avoiding downtime for maintenance, ensuring continuous and stable discharge, greatly increasing actual production efficiency, and achieving good results.
