Description

Technical Field

[0001] This invention relates to the technical field of spore powder drying and harvesting devices and methods, specifically to a drying and harvesting device and method for spore powder from a solid-state fermentation culture of Cordyceps militaris. Background Technology

[0002] Cordyceps spore powder is a fungal conidia produced by fermentation of a solid culture medium made from grains. It is in powder form and has high food and medicinal value. It can also be used to prepare microbial control agents. In order to facilitate the collection of spore powder, spore powder collection devices have appeared on the market, and with the development of technology, the functions of spore powder collection devices have gradually increased.

[0003] Chinese patent CN202011636193.1 discloses a spore powder collection device. This invention employs a handheld, controllable suction head with a clamshell-shaped structure at the suction tip, connected to a collection unit. The collection unit includes a fan for pumping spore powder, a cavity, and a dynamic filter mounting component. The dynamic filter is installed within this mounting component and comprises two drive shafts with belts for driving a filter screen. A drive component connects and drives the two drive shafts to rotate dynamically. The dynamic filter also includes a reverse blowing mechanism to prevent the filter screen from clogging. This invention solves the problem of small spore powder particles easily scattering. The backpack-style collection process is unaffected by the growth and cultivation environment of Ganoderma lucidum, preventing dust from flying and eliminating allergy issues. The spore powder collection process is waste-free, has low impurity levels, and achieves graded collection, improving the quality and utilization value of the spore powder.

[0004] Existing spore drying and harvesting devices and methods require manual cutting of the solid Cordyceps sinensis culture from the fermentation container into small pieces for drying after collection, increasing labor intensity and reducing efficiency. Once the small pieces of solid Cordyceps sinensis culture have reached a certain moisture content, they must be manually transferred to a spore collection device for spore collection, which is time-consuming and labor-intensive. Furthermore, the light spores are easily inhaled by operators, causing dust hazards. After spore collection, existing devices and methods require additional sieving tools when volume-based sieving is needed because the spores contain culture medium debris and mycelium, further reducing efficiency.

[0005] Therefore, a device and method for drying and harvesting spores from solid-state fermentation cultures of Cicada Flower are proposed to address the above problems. Summary of the Invention

[0006] To overcome the shortcomings of the existing technology, the purpose of this invention is to provide an apparatus and method that integrates the functions of drying solid-state fermentation culture of Cordyceps militaris and harvesting spores. This apparatus and method have the advantages of high spore harvesting efficiency, simple operation steps, no dust pollution, low labor intensity, and the ability to obtain spores of different purities at the same time.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A drying and harvesting device and method for spore powder from a solid-state fermentation culture of *Cicada nymph*, comprising a processing barrel and a conveyor, wherein the top of the processing barrel is provided with a top cover, and a support plate is fixed to the outer side of the top cover; a first rotating rod is connected to the outer side of the support plate; a conveyor belt is provided to the outer side of the first rotating rod, and a second rotating rod is connected to the left side of the conveyor belt; a processing plate is installed in the middle of the support plate, and an electric push rod is installed on the outer side of the processing plate; a pressing plate is provided at the bottom of the electric push rod; mounting bolts are connected to the outer side of the processing barrel, and a fan box is provided at the bottom of the processing barrel; and the bottom of the fan box... The fan box is fixed with a base. Locking rods are connected to both ends of the fan box. A heating plate is installed inside the fan box, and a heating tube is installed inside the heating plate. The conveyor is connected to the right side of the processing barrel. A sealing adjustment seat is installed on the outside of the conveyor, and a fixing bolt is connected to the outside of the sealing adjustment seat. A collection barrel is located on the right side of the conveyor, and a circular fixing seat is installed on the outside of the collection barrel. An adjusting bolt is connected to the outside of the circular fixing seat. A vibrator is installed at the bottom of the circular fixing seat, and a starting rod is connected to the bottom of the collection barrel. An adjusting rod is installed on the outside of the starting rod. A first screen is installed in the middle of the adjusting rod, and a second screen is installed at the top of the adjusting rod.

[0008] Preferably, the support plate and the first rotating rod are rotatably connected, and the first rotating rod and the second rotating rod form a chain drive structure through a conveyor belt.

[0009] Preferably, the processing plate is connected to the extrusion plate via an electric push rod to form a lifting structure, and the extrusion plate and the processing plate are slidably connected.

[0010] Preferably, the fan box is detachable from the processing barrel by mounting bolts, the processing barrel and the fan box are sealed together, and the processing barrel and the top cover are interlocked.

[0011] Preferably, the heating plate is connected to the fan box by a locking rod to form a locking structure, and multiple sets of heating tubes are installed at equal intervals on the inner side of the heating plate.

[0012] Preferably, the conveyor is detachable from the processing barrel via a sealing adjustment seat and fixing bolts, and the conveyor is sealed from the processing barrel via the sealing adjustment seat, and the processing barrel is connected to the collection barrel via the conveyor.

[0013] Preferably, the collection bucket is engaged with the circular fixed seat by adjusting bolts, and the circular fixed seat is telescopically connected to the base by vibrator, and four sets of vibrators are symmetrically arranged about the central axis of the circular fixed seat.

[0014] Preferably, the starting rod and the adjusting rod are rotatably connected, and the adjusting rod and the collection bucket are also rotatably connected.

[0015] Preferably, the adjusting rod and the first screen are welded together, and the first screen and the collection bucket form a rotating structure through the adjusting rod, and the filter hole diameter of the first screen is smaller than that of the second screen.

[0016] Preferably, it includes the following steps:

[0017] S1. First, place the base on a flat surface, then manually pull the lever. As the lever moves laterally on the fan box, it compresses the spring on the outside, placing the heating plate inside the fan box. Release the lever, and it returns to its original position due to the elasticity of the spring, locking into the slots at both ends of the heating plate to fix its position. Align the air inlet at the bottom of the processing barrel with the air outlet of the fan box, manually turn the four sets of mounting bolts to fix the position of the processing barrel, and place the top cover on top of the processing barrel. Fix the top cover itself using the locking blocks at both ends. Fix the conveyor in the middle of the base, and make the feed port of the conveyor pass through the discharge port of the processing barrel. The connection can be sealed by the sealing adjustment seat. Fix the position of the sealing adjustment seat by turning the fixing bolt into the sealing adjustment seat. Insert the discharge pipe at the other end of the conveyor into the feed port at the top of the collection barrel, place the collection barrel on the circular fixing seat, and fix the position of the collection barrel by turning the adjusting bolt.

[0018] S2. Secondly, during use, the collected cicada flower solid fermentation material is placed on the conveyor belt. The motor drives the first and second rotating rods to rotate. The first and second rotating rods rotate in place on the support plate. The rotation of the first and second rotating rods causes the conveyor belt to drive the cicada flower solid fermentation material to move until the fermentation material is directly under the extrusion plate. Then, the rotation of the first and second rotating rods stops, and the electric push rod is activated. The moving end of the electric push rod drives the extrusion plate to slide longitudinally on the processing plate until the extrusion plate fully contacts the fermentation material and cuts it into small pieces. Then, the electric push rod drives the extrusion plate to return to its original position, and the push plate installed on the top of the processing plate can push out the remaining fermentation material on the extrusion plate. The rotation of the first and second rotating rods causes the conveyor belt to carry the cut fermentation material to the feed port opened at the top of the processing barrel. After the conveying is completed, the feed port is blocked, and the next step of the work begins.

[0019] S3. Power on the blower box, which generates airflow into the processing barrel, lifting the small pieces of fermented material inside. Power on the heating plate, which heats multiple heating elements installed inside the barrel, raising the temperature inside the processing barrel and drying the lifted fermented material. Once the fermented material is dried, the spores on the surface will separate from it. Since the spores are relatively light, they will float above the fermented material. Power on the conveyor, which generates negative pressure to send the floating spores in the processing barrel into the collection barrel, starting the next step.

[0020] S4. Finally, the vibrator is activated, causing the collection bucket to vibrate longitudinally on the base. This sieving process separates the spore powder falling onto the second screen. Spore powder with a diameter smaller than the second screen falls onto the first screen, while spore powder with a diameter larger than the second screen is filtered out, thus achieving the sieving effect. A feeding box is connected to the discharge port at both ends of the collection bucket. The motor is activated, and the motor drives the starter rod to rotate. The starter rod rotates in place on the collection bucket and drives the adjusting rod to rotate through the gear on the outside. The rotation of the adjusting rod causes the first and second screens to rotate in place inside the collection bucket. The centrifugal force generated by the rotation of the first and second screens throws the spore powder to the discharge port at the edge of the collection bucket and it falls into the feeding box, thus achieving the sieving and feeding effect.

[0021] The novel advantages of this invention are:

[0022] 1. This invention, by setting up a conveyor belt and an extrusion plate, further facilitates the automatic cutting and feeding of solid cicada nymphs from a culture dish. The first and second rotating rods drive the conveyor belt to move, placing the solid fermented cicada nymphs from the culture dish onto the conveyor belt. The conveyor belt moves the fermented material until it is directly under the extrusion plate. Then, the first and second rotating rods stop rotating, and an electric push rod drives the extrusion plate to move up and down on the processing plate until the extrusion plate is completely pressed onto the fermented material. The extrusion plate cuts the fermented material into small pieces. The first and second rotating rods are then activated, and the conveyor belt continues to automatically feed the cut fermented material into the processing tank. If there is any cut fermented material stuck to the extrusion plate, the push plate at the top of the processing plate can be used to push the fermented material out of the extrusion plate, thus preventing fermented material from sticking to the extrusion plate.

[0023] 2. This invention, by incorporating a fan box and heating pipes, further facilitates the thorough drying and collection of the solid-state fermentation culture of *Cicada nymph*. The mounting bolts allow for easy fixation of the bottom of the processing barrel to the fan box, and a sealing layer is installed at the air outlet of the fan box to seal the connection between the processing barrel and the fan box. The heating plate and heating pipes increase the temperature inside the processing barrel, ensuring that the air blown out by the fan box is hot air, which lifts the fermented material inside the barrel for drying. This facilitates thorough drying of the fermented material. After drying, the spores on the fermented material are blown out and separated from the fermented material. The separated spores are then conveyed into a collection barrel via a conveyor housing, facilitating the automatic collection of the dried spores.

[0024] 3. This invention, by setting up a first screen and a second screen, further facilitates the sieving and collection of spore powder. An adjusting bolt secures the collection bucket to a circular base. A vibrator drives the collection bucket to longitudinally extend and retract on the base, accelerating the spore powder sieving rate. The second screen has a larger pore diameter than the first screen, facilitating the sieving of spore powder falling onto it. Smaller spore powder will fall through the second screen onto the first screen. The smaller spore powder collected on the first screen is then used to activate an adjusting rod that rotates in place on the collection bucket. This rotation causes both the first and second screens to rotate within the collection bucket. The centrifugal force generated by the uniform rotation of the first and second screens causes the sieving spore powder to be ejected through a discharge port. A feeding box is placed directly below the discharge port for convenient sieving and collection. Attached Figure Description

[0034] The technical solutions of the novel 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 novel invention, and not all embodiments. Based on the embodiments of the novel invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the novel invention.

[0035] Please see Figures 1 to 7As shown, a device and method for drying and harvesting spore powder from solid-state fermentation culture of *Cicada nymph* includes a processing barrel 1 and a conveyor 16. A top cover 2 is provided on the top of the processing barrel 1, and a support plate 3 is fixed to the outer side of the top cover 2. A first rotating rod 4 is connected to the outer side of the support plate 3. A conveyor belt 5 is provided to the outer side of the first rotating rod 4, and a second rotating rod 6 is connected to the left side of the conveyor belt 5. A processing plate 7 is installed in the middle of the support plate 3, and an electric push rod 8 is installed on the outer side of the processing plate 7. A pressing plate 9 is provided at the bottom of the electric push rod 8. Mounting bolts 10 are connected to the outer side of the processing barrel 1, and a fan box 11 is provided at the bottom of the processing barrel 1. A base 12 is fixed to the bottom of the fan box 11, and clamping rods 13 are connected to the left and right ends of the fan box 11. A heating plate 14 is provided inside the casing 11, and a heating tube 15 is installed inside the heating plate 14. A conveyor 16 is connected to the right side of the processing barrel 1, and a sealing adjustment seat 17 is provided on the outside of the conveyor 16. A fixing bolt 18 is connected to the outside of the sealing adjustment seat 17. A collection barrel 19 is provided on the right side of the conveyor 16, and a circular fixing seat 20 is provided on the outside of the collection barrel 19. An adjusting bolt 21 is connected to the outside of the circular fixing seat 20. A vibrator 22 is installed at the bottom of the circular fixing seat 20, and a starting rod 23 is connected to the bottom of the collection barrel 19. An adjusting rod 24 is provided on the outside of the starting rod 23. A first screen 25 is installed in the middle of the adjusting rod 24, and a second screen 26 is installed at the top of the adjusting rod 24.

[0036] Please see Figures 1 to 3 As shown, the support plate 3 and the first rotating rod 4 are rotatably connected, and the first rotating rod 4 forms a chain drive structure with the second rotating rod 6 through the conveyor belt 5. The rotation of the first rotating rod 4 and the second rotating rod 6 can drive the conveyor belt 5 to perform transmission motion. The solid fermentation material of cicada flower on the culture dish is placed on the conveyor belt 5, and the fermentation material is transmitted by the conveyor belt 5. After the fermentation material is moved to directly below the extrusion plate 9, the rotation of the first rotating rod 4 and the second rotating rod 6 is stopped, which facilitates the automatic movement of the fermentation material.

[0037] Please see Figures 1 to 3 As shown, the processing plate 7 forms a lifting structure with the extrusion plate 9 via the electric push rod 8, and the extrusion plate 9 and the processing plate 7 are slidably connected. With this setting, when the electric push rod 8 is activated, the extrusion plate 9 is driven to move up and down on the processing plate 7 through the movable end of the electric push rod 8 until the extrusion plate 9 is completely pressed onto the fermented material. The extrusion plate 9 cuts the fermented material into small pieces. If there is any fermented material stuck inside the extrusion plate 9, the extruded material can be pushed out by the push plate set on the top of the processing plate 7, thereby avoiding the fermented material sticking to the extrusion plate 9 and facilitating the automatic cutting and processing of the fermented material.

[0038] Please see Figures 1 to 2As shown, the fan box 11 is detachable from the processing barrel 1 by mounting bolts 10, and the processing barrel 1 and the fan box 11 are sealed together. The processing barrel 1 and the top cover 2 are also interlocked. With this configuration, the processing barrel 1 is placed on the fan box 11, and the position of the processing barrel 1 is fixed by rotating the mounting bolts 10. The air blown out by the fan box 11 blows the fermented material in the processing barrel 1 to dry it. The top cover 2 is interlocked with the processing barrel 1, which makes it easy to fix the position of the top cover 2.

[0039] Please see Figures 1 to 5 As shown, the heating plate 14 is engaged with the fan box 11 via the locking rod 13, and multiple sets of heating tubes 15 are installed at equal intervals on the inner side of the heating plate 14. With this arrangement, the heating plate 14 is powered to generate heat energy through the heating tubes 15, thereby increasing the temperature inside the processing drum 1. By setting multiple sets of heating tubes 15, the temperature can be increased quickly and the drying rate can be accelerated. When it is necessary to remove the heating plate 14, the locking rod 13 can be pulled outward by hand. The locking rod 13 moves outward on the fan box 11 until one end of the locking rod 13 leaves the slot starting from the outer side of the heating plate 14, thus making it easy to remove the heating plate 14 from the fan box 11.

[0040] Please see Figures 1 to 4 As shown, the conveyor 16 forms a detachable structure with the processing barrel 1 through the sealing adjustment seat 17 and the fixing bolt 18, and the conveyor 16 forms a sealed structure with the processing barrel 1 through the sealing adjustment seat 17. The processing barrel 1 also forms a connected structure with the collection barrel 19 through the conveyor 16. With this arrangement, when the conveyor 16 is working, the negative pressure generated by the conveyor 16 sends the relatively light spore powder into the collection barrel 19. The sealing adjustment seat 17 and the fixing bolt 18 make it easy to seal and fix the conveyor 16 to the processing barrel 1.

[0041] Please see Figures 1 to 7 As shown, the collection bucket 19 is engaged with the circular fixed seat 20 by adjusting bolt 21, and the circular fixed seat 20 is telescopically connected to the base 12 by vibrator 22. Four sets of vibrators 22 are symmetrically arranged about the central axis of the circular fixed seat 20. With this arrangement, the collection bucket 19 can be placed on the circular fixed seat 20 and the position of the collection bucket 19 can be fixed by adjusting bolt 21. The vibrators 22 drive the collection bucket 19 to vibrate up and down, which facilitates the improvement of the spore powder screening and feeding rate in the collection bucket 19.

[0042] Please see Figures 6 to 7As shown, the starting rod 23 and the adjusting rod 24 are rotatably connected, and the adjusting rod 24 and the collection bucket 19 are also rotatably connected. With this configuration, the starting rod 23 can be rotated, which in turn drives the adjusting rod 24 to rotate, making it easy to make the starting rod 23 rotate at a constant speed inside the collection bucket 19.

[0043] Please see Figures 6 to 7 As shown, the adjusting rod 24 and the first screen 25 are welded together, and the first screen 25 forms a rotating structure with the collection bucket 19 through the adjusting rod 24. The diameter of the filter holes of the first screen 25 is smaller than that of the second screen 26. By setting the diameter of the filter holes of the second screen 26 to be larger than that of the first screen 25, it is convenient to screen the spore powder that falls onto the second screen 26. The smaller diameter spore powder will fall onto the first screen 25 through the second screen 26. The smaller diameter spore powder collected on the first screen 25 is driven by the adjusting rod 24 to rotate the first screen 25 and the second screen 26 in place within the collection bucket 19. The centrifugal force generated by the uniform rotation of the first screen 25 and the second screen 26 causes the screened spore powder to rotate and be thrown out to the discharge port. A feeding box is placed directly below the discharge port to facilitate screening and collection.

[0044] Working principle: First, the processing barrel 1 is placed on the fan box 11. The mounting bolts 10 are manually turned to fix the processing barrel 1 in place. Then, the top cover 2 is placed on the processing barrel 1, locking it in place. The collected solid-state fermented cicada flower culture from the culture container is placed on the conveyor belt 5. The motor is then activated, driving the second rotating rod 6 and the first rotating rod 4 to rotate in place on the support plate 3. The first rotating rod 4 and the second rotating rod 6 cause the conveyor belt 5 to move the solid-state fermented cicada flower culture until the solid-state fermented cicada flower culture is completely fermented. After the fermented material is moved directly under the extrusion plate 9, the electric push rod 8 is activated. The moving end of the electric push rod 8 drives the extrusion plate 9 to slide up and down on the processing plate 7 until the extrusion plate 9 is completely pressed onto the fermented material and cut into small pieces. Then, the electric push rod 8 drives the extrusion plate 9 to return to its original position. The push plate set on the top of the processing plate 7 pushes out the fermented material in the extrusion plate 9, thereby preventing the fermented material from sticking to the extrusion plate 9. The first rotating rod 4 and the second rotating rod 6 are activated to rotate, and the conveyor belt 5 continues to automatically feed the cut fermented material into the processing barrel 1.

[0045] Secondly, the lever 13 is manually pulled outward. As the lever 13 moves outward on the fan box 11, it compresses the spring on the outer side, placing the heating plate 14 at the air outlet of the fan box 11. The lever 13 is then released, and it returns to its original position due to the spring's elasticity, locking into the slot on the outer side of the heating plate 14, thus fixing the position of the heating plate 14 and enabling it to operate. The heating plate 14 drives multiple sets of heating tubes 15 on the inner side to heat the interior, raising the temperature of the processing drum 1. Temperature is set to operate the blower box 11. The airflow generated by the blower box 11 blows up the fermented material in the processing barrel 1. The heat energy generated by the heating pipe 15 is used to dry the solid cicada flower fermented material. After the fermented material is dried, it will separate from the spore powder on the surface. The conveyor 16 is then set to operate. The negative pressure generated by the conveyor 16 sucks out the separated spore powder in the processing barrel 1 and sends it into the collection barrel 19. The conveyor 16 is conveniently sealed and fixed to the processing barrel 1 by the sealing adjustment seat 17 and the fixing bolt 18.

[0046] Finally, the collection bucket 19 is placed on the circular fixed base 20. The position of the collection bucket 19 is then fixed by manually rotating the adjusting bolt 21. The vibrator 22 is then activated, causing the collection bucket 19 to vibrate longitudinally on the base 12. This vibrates and sieves the spore powder on the second screen 26. Smaller spore powder on the second screen 26 falls onto the first screen 25, while larger spore powder is filtered out by the second screen 26. When the sieved spore powder needs to be discharged, two sets of discharge boxes are sealed and connected to the two discharge ports of the collection bucket 19. The motor is then activated, driving the starter rod 23 to rotate. When the collection bucket 19 rotates in place, the gear on the outside drives the adjusting rod 24 to rotate. The rotation of the adjusting rod 24 drives the first screen 25 and the second screen 26 to rotate in place within the collection bucket 19. The centrifugal force generated by the uniform rotation of the first screen 25 and the second screen 26 causes the sieved spore powder to rotate and be thrown out to the discharge port. A feeding box is placed directly below the discharge port. Through the above process, the larger diameter spore powder can be filtered onto the second screen 26, and the smaller diameter spore powder can be filtered onto the first screen 25. By opening two sets of discharge ports at the collection bucket 19, spore powder of different diameters on the first screen 25 and the second screen 26 can be collected, thereby realizing the graded collection of spore powder.

10. A method for drying and harvesting spore powder from a solid-state fermentation culture of *Cicada nymph*, characterized in that... The device for drying and harvesting spores from a solid-state fermentation culture of *Cicada nymph* as described in any one of claims 1-9 includes the following steps: S1. First, place the base (12) on a flat surface, then manually pull the lever (13). As the lever (13) moves laterally on the fan box (11), it will compress the spring on the outside. Place the heating plate (14) inside the fan box (11), release the lever (13), and the lever (13) will return to its original position through the elasticity of the spring and be locked into the slots at both ends of the heating plate (14). Align the air inlet at the bottom of the processing barrel (1) with the air outlet of the fan box (11), manually rotate the four sets of mounting bolts (10) to fix the position of the processing barrel (1), and place the top cover (2) on top of the processing barrel (1). The locking blocks at both ends of the cover (2) fix its own position, fix the conveyor (16) in the middle of the base (12), and make the feed port of the conveyor (16) pass through the discharge port of the processing barrel (1). The connection can be sealed by the sealing adjustment seat (17), and the position of the sealing adjustment seat (17) is fixed by turning the fixing bolt (18) into the sealing adjustment seat (17). Then, the discharge pipe at the other end of the conveyor (16) is inserted into the feed port opened at the top of the collection barrel (19), the collection barrel (19) is placed on the circular fixing seat (20), and the position of the collection barrel (19) is fixed by turning the adjustment bolt (21). S2. Next, during use, the collected cicada flower solid fermented material, which has undergone dehumidification and pre-drying treatment, is placed on the conveyor belt (5). The motor drives the first rotating rod (4) and the second rotating rod (6) to rotate. The first rotating rod (4) and the second rotating rod (6) will rotate in place on the support plate (3). The rotation of the first rotating rod (4) and the second rotating rod (6) causes the conveyor belt (5) to drive the cicada flower solid fermented material to perform transmission motion until the fermented material is conveyed to the area directly below the extrusion plate (9). Then, the rotation of the first rotating rod (4) and the second rotating rod (6) is stopped, and the electric push rod (8) is activated. The process involves using the movable end of an electric push rod (8) to drive the extrusion plate (9) to slide longitudinally on the processing plate (7) until the extrusion plate (9) fully contacts the fermented material and cuts it into small pieces. Then, the electric push rod (8) drives the extrusion plate (9) back to its original position, and the push plate installed on the top of the processing plate (7) pushes out the remaining fermented material on the extrusion plate (9). The first rotating rod (4) and the second rotating rod (6) rotate to make the conveyor belt (5) carry the fermented material cut into small pieces to the feed inlet opened at the top of the processing tank (1). After the conveying is completed, the feed inlet is blocked, and the next step of the work begins. S3. Start the fan box (11). The airflow generated by the fan box (11) is blown into the processing barrel (1) and blows up the small pieces of fermented material in the processing barrel (1). The heating plate (14) is activated and heats the multiple sets of heating tubes (15) installed inside the heating plate (14) to generate heat and increase the temperature inside the processing barrel (1). This dries the blown-up fermented material. When the fermented material is dried, the spore powder on the surface will separate from it. Since the spore powder is relatively light, it will be above the fermented material. The conveyor (16) is activated and the negative pressure generated by the conveyor (16) can send the floating spore powder in the processing barrel (1) into the collection barrel (19) to start the next step. S4. Finally, start the vibrator (22). The vibrator (22) drives the collection bucket (19) to vibrate longitudinally on the base (12), thereby sieving the spore powder falling on the second screen (26). Spore powder with a diameter smaller than the second screen (26) will fall onto the first screen (25), while spore powder with a diameter larger than the second screen (26) will be filtered out, thus achieving the sieving effect. The discharge ports at both ends of the collection bucket (19) are connected to the discharge boxes to power the motor. The machine drives the starter rod (23) to rotate. The starter rod (23) rotates in place on the collection bucket (19) and drives the adjusting rod (24) to rotate through the gear set on the outside. The rotation of the adjusting rod (24) can drive the first screen (25) and the second screen (26) to rotate in place inside the collection bucket (19). The centrifugal force generated by the rotation of the first screen (25) and the second screen (26) throws the spore powder to the discharge port opened at the edge of the collection bucket (19) and drops it into the feeding box, thereby achieving the effect of screening and feeding.
