Description

Technical Field

[0001] The present invention belongs to the technical field of raw material pretreatment, and specifically relates to a pulverizing and processing device for polygonatum sibiricum raw materials. Background Art

[0002] In the fields of modern biomedicine and functional foods, polygonatum sibiricum, as an important plant with both medicinal and edible properties, has received extensive attention due to the significant antioxidant, hypoglycemic, anti-tumor, anti-inflammatory and antibacterial, and immune-enhancing effects of its polysaccharide components. The efficient extraction of polygonatum sibiricum polysaccharides has become a key link in exploring its potential value, and raw material pretreatment, as a pre-step in the extraction process, directly affects the efficiency and quality of subsequent extraction.

[0003] Currently, in the raw material pretreatment for the extraction of polygonatum sibiricum polysaccharides, there are already various technical solutions. For example, some traditional pretreatment devices mainly focus on the cleaning and simple cutting of polygonatum sibiricum raw materials, and use mechanical structures to achieve the initial physical form change of the raw materials to meet the basic requirements of subsequent extraction operations.

[0004] A raw material pretreatment device for the extraction of plant polysaccharides disclosed in Chinese Patent Publication (Announcement) No. CN216093472U uses the heat generated by an electric heating wire driven by a blower to dry the plant, and to a certain extent, realizes the rapid and convenient pretreatment before plant extraction. However, such existing technologies generally have limitations. In practical applications, the pretreatment of polygonatum sibiricum raw materials requires multiple complex steps, including crushing, grinding, etc., to fully destroy the plant cell structure and improve the dissolution rate of polysaccharides.

[0005] However, most of the existing devices can only complete single or a few pretreatment operations. If comprehensive pretreatment is to be achieved, multiple devices are often required to process step by step. This not only increases the equipment investment cost and floor area, but also makes the entire pretreatment process cumbersome and complex, greatly reducing the efficiency of raw material processing, and further seriously affecting the subsequent extraction progress of polygonatum sibiricum polysaccharides. Moreover, multiple transfers of raw materials during the step-by-step processing may also lead to raw material loss and contamination, further reducing the yield and quality of the final product.

[0006] Therefore, there is an urgent practical need to develop a pulverizing and processing device for polygonatum sibiricum raw materials that can integrate multiple pretreatment functions and operate efficiently and stably. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a pulverizing and processing device for polygonatum sibiricum raw materials, to solve the problems of complex pretreatment process and low efficiency in the existing technology for the extraction of polygonatum sibiricum polysaccharides, to achieve efficient pretreatment operations such as crushing and grinding of polygonatum sibiricum raw materials, to improve the efficiency of raw material processing, and to enhance the extraction quality of subsequent polygonatum sibiricum polysaccharides.

[0008] The solution adopted by the present invention is as follows: A Polygonatum sibiricum raw material crushing and processing device, characterized in that it includes:

[0009] A housing, one side of the back of the housing is fixedly connected with a bracket;

[0010] A first motor, fixed on the upper surface of the bracket, and the output end of the first motor is fixedly connected with a first crushing roller;

[0011] A second crushing roller, rotatably connected to the inner side surface of the housing and close to one side of the first crushing roller, and gears are fixedly connected to one side of the outer surfaces of the first crushing roller and the second crushing roller, and are driven to mesh with each other through the gears;

[0012] Small driving wheels, fixed on the outer surfaces of the first crushing roller and the second crushing roller close to the gears;

[0013] A belt, the inner side surface of which is in transmission connection with the small driving wheels;

[0014] A large driving wheel, the bottom of the inner side surface of the belt is in transmission connection with the large driving wheel;

[0015] A grinding roller, fixed on the inner side surface of the housing close to the large driving wheel and fixedly connected with the large driving wheel, and the power is transmitted through the small driving wheels, the belt and the large driving wheel to drive the grinding roller to rotate.

[0016] By adopting the above technical solution, the first motor drives the first crushing roller, and then the second crushing roller is driven by gear transmission, realizing the primary crushing of the Polygonatum sibiricum raw material. At the same time, the power is transmitted to the grinding roller by using the small driving wheels, the belt and the large driving wheel, so that the grinding roller rotates to further grind the raw material. The beneficial effect of this design is that the functions of crushing and grinding are integrated in one device, avoiding the use of multiple devices to process the Polygonatum sibiricum raw material step by step, reducing the equipment investment cost and floor area, simplifying the pretreatment process, improving the raw material processing efficiency, and thus being beneficial to the subsequent extraction of Polygonatum sibiricum polysaccharide.

[0017] In a preferred embodiment, a scraping seat is fixed on the inner side surface of the housing close to the grinding roller;

[0018] A cleaning brush is rotatably connected to the inner side surface of the housing close to the first crushing roller and the second crushing roller, the scraping seat contacts the grinding roller, and the cleaning brush contacts the first crushing roller and the second crushing roller.

[0019] By adopting the above technical solution, the scraping seat contacts the grinding roller, and the cleaning brush contacts the first crushing roller and the second crushing roller. During the operation of the device, the scraping seat can timely scrape off the residue of the polygonatum odoratum raw material attached to the surface of the grinding roller, and the cleaning brush can clean the residue on the surfaces of the first crushing roller and the second crushing roller. This can prevent the influence of raw material residue on the subsequent treatment effect, ensure the quality of crushing and grinding, and at the same time facilitate the maintenance of the equipment, extend the service life of the equipment, and ensure the long-term stable operation of the device.

[0020] In a preferred embodiment, the heating plates are fixed on both sides of the inner wall of the housing.

[0021] By adopting the above technical solution, heating plates are fixed on both sides of the inner wall of the housing, which can generate heat to heat the raw material during the pretreatment of the polygonatum odoratum raw material. Its beneficial effect is to play an auxiliary drying role, making the cell structure of polygonatum odoratum easier to be destroyed by subsequent crushing and grinding operations in the dry state, helping to improve the dissolution rate of polysaccharides, and thus enhancing the efficiency and quality of subsequent extraction of polygonatum odoratum polysaccharides.

[0022] In a preferred embodiment, the first conical tooth is fixed at one end of the second crushing roller away from the gear;

[0023] The second conical tooth is meshed and connected to the outer surface of the first conical tooth;

[0024] The connecting rod is fixed to the lower surface of the second conical tooth;

[0025] The support plate is fixed on the back of the housing near one side of the connecting rod and is rotatably connected to the connecting rod.

[0026] By adopting the above technical solution, when the second crushing roller rotates, the second conical tooth meshed therewith is driven to rotate by the first conical tooth, and then the connecting rod rotates. The beneficial effect of this structure is to transmit and convert the rotational power of the second crushing roller, providing a power basis for subsequent realization of other functions (such as driving the fan blade to rotate), increasing the linkage between the components inside the device, and making the functions of the device more abundant and efficient.

[0027] In a preferred embodiment, the first rotating rod is rotatably connected to the middle of the inner bottom wall of the housing;

[0028] The fan blade is fixed to the top of the outer surface of the first rotating rod. The first rotating rod penetrates through the housing, and both the first rotating rod and the connecting rod protrude from the lower surface of the housing.

[0029] By adopting the above technical solution, the first rotating rod is rotatably connected to the middle of the inner bottom wall of the housing, and a fan blade is fixed to the top of its outer surface. Both the first rotating rod and the connecting rod protrude from the lower surface of the housing. When the connecting rod rotates, the first rotating rod can be driven to rotate through transmission, so that the fan blade rotates. On the one hand, the fan blade can turn the polygonatum odoratum raw materials in the housing, making the raw materials heat more evenly and enhancing the auxiliary drying effect of the heating plate; on the other hand, when heat is generated during the operation of the device, the rotation of the fan blade can promote the air flow in the housing, achieve heat dissipation, and prevent the raw material quality and equipment performance from being affected by too high temperature.

[0032] A tension pulley, the middle of the inner side surface of the synchronous belt is slidably connected to the tension pulley, and the tension pulley is rotatably connected to the housing.

[0033] By adopting the above technical solution, synchronous pulleys are fixed to the bottoms of the outer surfaces of the connecting rod and the first rotating rod, and are connected by a synchronous belt in transmission. The middle of the inner side surface of the synchronous belt is slidably connected to the tension pulley rotatably connected to the housing. The tension pulley can adjust the tension degree of the synchronous belt to ensure stable and reliable transmission between the synchronous pulleys. This structure ensures the accuracy and stability of the power transmission between the connecting rod and the first rotating rod, enables the fan blade to rotate continuously and stably, and better plays the role of turning the raw materials and dissipating heat.

[0034] In a preferred embodiment, a feed hopper is fixed to the upper surface of the housing;

[0035] A discharge channel is fixed to the bottom of the outer surface of the housing.

[0036] By adopting the above technical solution, the feed hopper on the upper surface of the housing facilitates the input of polygonatum odoratum raw materials into the device, and the operation is convenient and fast. The discharge channel at the bottom of the outer surface of the housing is used to discharge the pretreated polygonatum odoratum raw materials, making the whole pretreatment process form a complete process, realizing the orderly entry and exit of raw materials, and improving the use convenience and working efficiency of the device.

[0037] In a preferred embodiment, a guide plate is fixed to the inner bottom wall of the housing;

[0038] Card slots are opened on both sides of the inner side surface of the discharge channel;

[0039] A baffle is clamped to the inner side surface of the card slot.

[0040] By adopting the above technical solution, the deflector on the inner bottom wall of the housing can guide the pre-treated raw materials to smoothly flow towards the discharge channel, preventing the raw materials from accumulating in the housing and ensuring smooth discharging. The clamping grooves on both sides of the inner side surface of the discharge channel cooperate with the baffles clamped therein, and the opening and closing of the discharge channel can be controlled as needed. In this way, raw material leakage can be prevented during the pre-treatment process, and the raw materials can be discharged by opening the baffle when discharging is required, improving the controllability and practicability of the device.

[0041] In a preferred embodiment, two sets of the small driving wheels, belts, large driving wheels and grinding rollers are provided, and the two sets of grinding rollers are both rotatably connected to the middle of the inner side surface of the housing.

[0042] By adopting the above technical solution, two sets of the small driving wheels, belts, large driving wheels and grinding rollers are provided, and the two sets of grinding rollers are both rotatably connected to the middle of the inner side surface of the housing. This design can simultaneously perform crushing and grinding treatments on more polygonatum sibiricum raw materials. Compared with a single set structure, the working efficiency of the device is greatly improved, and the demand for pre-treatment of raw materials for large-scale extraction of polygonatum polysaccharide can be met.

[0043] In a preferred embodiment, two sets of the scraping seats and cleaning brushes are provided, the two sets of scraping seats are respectively in contact with the two sets of grinding rollers, and the two sets of cleaning brushes are respectively in contact with the first crushing roller and the second crushing roller.

[0044] By adopting the above technical solution, two sets of the scraping seats and cleaning brushes are provided, the two sets of scraping seats are respectively in contact with the two sets of grinding rollers, and the two sets of cleaning brushes are respectively in contact with the first crushing roller and the second crushing roller. When the number of sets of grinding rollers and crushing rollers is increased, the two sets of scraping seats and cleaning brushes can respectively clean the corresponding rollers, ensuring that the surfaces of each set of rollers can be kept clean, guaranteeing the crushing and grinding effects, and at the same time being beneficial to the maintenance and upkeep of the equipment, enabling the device to maintain a good working state while operating efficiently.

[0045] In a preferred embodiment, a water tank is fixed to one side of the bottom of the outer surface of the housing away from the discharge channel;

[0046] A drain pipe is fixed to the bottom of the outer surface of the water tank;

[0047] A fixing seat is fixed to the middle of the inner bottom wall of the water tank;

[0048] A conveying cylinder is fixed to the upper surface of the fixing seat;

[0049] Drain holes are uniformly formed in a circumferential array on the outer surface of the conveying cylinder.

[0050] By adopting the above technical solution, the conveying cylinder is used for conveying the processed polygonatum sibiricum. During the conveying process, the residual moisture on the surface of the polygonatum sibiricum is discharged through a plurality of drain holes on the surface of the conveying cylinder, which can significantly reduce the initial moisture content of the raw material. In this way, the subsequent drying process will be more efficient and the drying time can be greatly shortened. The discharged water is received by the water tank, and the drain pipe discharges the received water to a designated location. These waters can be reused for the cleaning process of polygonatum sibiricum after simple filtration and treatment, realizing the recycling of water resources.

[0051] In a preferred embodiment, a second motor is fixed to the lower surface of the conveying cylinder. The output end of the second motor is fixedly connected to a second rotating rod, and a screw conveyor blade is fixedly connected to the outer surface of the second rotating rod.

[0052] A crank is fixed to the top of the outer surface of the second rotating rod. One side of the upper surface of the crank away from the second rotating rod is rotatably connected to a connecting arm.

[0054] A corrugated pipe is fixed to one end of the discharge pipe, and the corrugated pipe is fixedly connected to the other side of the lower surface of the rocker.

[0055] By adopting the above technical solution, the second motor drives the second rotating rod to rotate, so that the screw conveyor blade conveys the processed polygonatum sibiricum raw material, realizing the continuous conveying of the raw material, enabling the polygonatum sibiricum raw material to continuously enter the subsequent processing link and realizing continuous production. At the same time, during the conveying process, the polygonatum sibiricum raw material is continuously tumbled, which can better reduce the residual moisture on the surface of the polygonatum sibiricum raw material. When the second rotating rod rotates, the crank rotates accordingly. Through the connecting arm and the support rod, the rocker rotates and swings with one side of the discharge pipe as the center, so that the other side of the rocker drives the corrugated pipe to perform regular reciprocating swings, making the polygonatum sibiricum raw material more evenly distributed on the feed hopper during the conveying process, helping to improve the conveying efficiency, avoiding material accumulation or blockage, and ensuring that the raw material can smoothly enter the subsequent processing link.

[0056] Beneficial effects:

[0057] I. High-efficiency integrated pretreatment function: Through a unique structural design, the present invention integrates two key pretreatment operations of crushing and grinding in one device. The first motor drives the first crushing roller, and drives the second crushing roller through gear transmission to achieve the primary crushing of the polygonatum odoratum raw material. At the same time, the power is transmitted to the grinding roller by means of a small driving wheel, a belt and a large driving wheel to further grind the crushed raw material. This integrated design avoids the step-by-step treatment using multiple devices, greatly reduces the equipment investment cost and floor area, simplifies the originally cumbersome and complex pretreatment process, significantly improves the raw material treatment efficiency, and lays a solid foundation for the efficient extraction of polygonatum polysaccharide in the follow-up.

[0058] II. Ensure the continuous and stable operation of the equipment: The scraping seat fixed on one side close to the grinding roller and the cleaning brush rotatably connected on one side close to the first crushing roller and the second crushing roller play an important role during the operation of the device. The scraping seat can timely scrape off the residues of polygonatum odoratum raw materials attached to the surface of the grinding roller, and the cleaning brush can clean the residues on the surfaces of the first crushing roller and the second crushing roller. This not only prevents the influence of raw material residue on the subsequent treatment effect, ensures the quality of crushing and grinding, but also facilitates the daily maintenance of the equipment, effectively extends the service life of the equipment, ensures the long-term stable operation of the device, reduces the downtime caused by equipment failures, and further improves the production efficiency.

[0059] III. Convenient feeding and discharging design: The feeding hopper on the upper surface of the housing facilitates the operator to put the polygonatum odoratum raw material into the device, and the operation is simple and fast. The discharging channel at the bottom of the outer surface of the housing is used to discharge the pretreated polygonatum odoratum raw material, forming a complete and smooth pretreatment process. The guide plate on the inner bottom wall of the housing guides the pretreated raw material to smoothly flow towards the discharging channel, avoiding the accumulation of raw materials in the housing. The clamping grooves on both sides of the inner side surface of the discharging channel cooperate with the baffles clamped therein, and the opening and closing of the discharging channel can be flexibly controlled according to actual needs, preventing the leakage of raw materials during the pretreatment process, and improving the controllability and practicability of the device.

[0060] IV. Greatly improve the working efficiency: There are two groups of small driving wheels, belts, large driving wheels and grinding rollers. The two groups of grinding rollers work simultaneously, and can crush and grind more polygonatum odoratum raw materials at the same time. Compared with the single-group structure, the working efficiency of the device is greatly improved, which can meet the needs of raw material pretreatment for large-scale extraction of polygonatum polysaccharide and provides strong support for industrial production. At the same time, the two groups of scraping seats and cleaning brushes adapted thereto clean the corresponding rollers respectively, ensuring that the surfaces of each group of rollers can be kept clean while working efficiently, guaranteeing the crushing and grinding effects, and further improving the overall working performance of the device.

[0061] V. Design for reducing the initial moisture content of raw materials and uniform material distribution: The second motor drives the second rotating rod to rotate, enabling the auger conveying blades to convey the cleaned polygonatum sibiricum raw materials, achieving continuous production. Meanwhile, during the conveying process, the polygonatum sibiricum raw materials are continuously tumbled, and the residual moisture on the surface of the polygonatum sibiricum is discharged through multiple drainage holes on the surface of the conveying cylinder, which can significantly reduce the initial moisture content of the raw materials. The water tank receives the discharged water, and the drain pipe discharges the received water to a designated location, realizing the recycling of water resources. When the second rotating rod rotates, through the reciprocating swing mechanism, the polygonatum sibiricum raw materials are more evenly distributed on the feeding hopper during the conveying process, which helps to improve the conveying efficiency, avoid material accumulation or blockage, and ensure that the raw materials can smoothly enter the subsequent processing links.

[0062] As described above, through the ingenious design and coordinated operation of each structure, the present invention has successfully solved the problems of complex pretreatment process and low efficiency in the pretreatment of raw materials for extracting polygonatum polysaccharide in the prior art, achieved efficient and comprehensive pretreatment of polygonatum sibiricum raw materials, and has significant positive significance for improving the overall quality and efficiency of polygonatum polysaccharide extraction.

[0081] Regarding the foregoing and other technical contents, features and effects of the present invention, they will be clearly presented in the following detailed description in conjunction with the Figure 1-7 reference to the embodiments. The structural contents mentioned in the following embodiments are all with reference to the accompanying drawings of the specification.

[0082] The following will describe the exemplary embodiments of the present invention with reference to the drawings.

[0083] As Figure 1-5 shown, a pulverizing and processing device for polygonatum odoratum raw materials includes a housing 1. One side of the back surface of the housing 1 is fixedly connected with a bracket 11. The upper surface of the bracket 11 is fixedly connected with a first motor 12. The output end of the first motor 12 is fixedly connected with a first crushing roller 13. One side of the inner side surface of the housing 1 close to the first crushing roller 13 is rotatably connected with a second crushing roller 14. One side of the outer surfaces of the first crushing roller 13 and the second crushing roller 14 is fixedly connected with a gear 15. One side of the outer surfaces of the first crushing roller 13 and the second crushing roller 14 close to the gear 15 is fixedly connected with a small driving wheel 16. The inner side surface of the small driving wheel 16 is drivingly connected with a belt 17. The bottom of the inner side surface of the belt 17 is drivingly connected with a large driving wheel 18. One side of the inner side surface of the housing 1 close to the large driving wheel 18 is fixedly connected with a grinding roller 19. The grinding roller 19 is fixedly connected with the large driving wheel 18.

[0084] During specific use, through the arrangement of the first motor 12, the first crushing roller 13, the second crushing roller 14, and the grinding roller 19, gears 15 are fixedly connected to the outer surfaces of both the first crushing roller 13 and the second crushing roller 14. The two sets of gears 15 mesh with each other. The bracket 11 supports and fixes the first motor 12 to ensure the stability of the first motor 12 during use. The cleaned polygonatum raw materials enter the housing 1. The first motor 12 drives the first crushing roller 13 to rotate. Under the action of the two sets of gears 15, the first crushing roller 13 and the second crushing roller 14 rotate relative to each other to preliminarily crush the polygonatum raw materials. The preliminarily crushed polygonatum raw materials slide downward. The small driving wheels 16 on the outer surfaces of the first crushing roller 13 and the second crushing roller 14 drive the large driving wheels 18 to rotate through the belt 17, so that the two sets of grinding rollers 19 rotate relative to each other to grind the preliminarily crushed polygonatum raw materials, making their particle sizes uniform. The polygonatum with uniform particle size has a relatively large and evenly distributed surface area, and the solvent can more fully contact the polysaccharide components in the polygonatum, thereby accelerating the dissolution and diffusion of the polysaccharides and improving the extraction efficiency. By combining the two steps of crushing and grinding, the operation process is simplified, the time and labor costs for transferring raw materials between different devices are reduced, and the production efficiency is significantly improved. The integrated operation adopts a non-contact method, avoiding the possible contamination of the polygonatum raw materials during pretreatment, ensuring the purity and integrity of the polygonatum raw materials, and at the same time achieving the effect of driving multiple components with one driving source, fully allocating the use of energy, saving production costs, and reducing the work burden of personnel.

[0085] Please refer to Figure 3 and Figure 4 , in this embodiment, a scraping seat 2 is fixedly connected to one side of the inner side surface of the housing 1 close to the grinding roller 19, and cleaning brushes 21 are rotatably connected to both sides of the inner side surface of the housing 1 close to the first crushing roller 13 and the second crushing roller 14.

[0086] During specific use, through the arrangement of the scraping seat 2 and the cleaning brushes 21, the top of the scraping seat 2 is of an inclined structure, which is used to guide the preliminarily crushed raw materials to avoid flowing out of the use range of the grinding roller 19, and the bottom can scrape the raw materials remaining on the surface of the grinding roller 19. The cleaning brushes 21 clean the crushed raw materials remaining on the surfaces of the first crushing roller 13 and the second crushing roller 14 to avoid waste of raw materials.

[0087] Please refer to Figure 3 , in this embodiment, heating plates 3 are fixedly connected to both sides of the inner wall of the housing 1.

[0088] During specific use, through the arrangement of the heating plates 3, the heating plates 3 can heat the lower half space of the housing 1 to dry the wet polygonatum raw material particles after grinding, which is convenient for storage.

[0089] In this embodiment, a first bevel gear 4 is fixedly connected to one end of the second crushing roller 14 away from the gear 15. The outer surface of the first bevel gear 4 is meshed with a second bevel gear 41. A connecting rod 42 is fixedly connected to the lower surface of the second bevel gear 41. A support plate 43 is fixedly connected to one side of the back surface of the housing 1 close to the connecting rod 42. The support plate 43 is rotatably connected to the connecting rod 42.

[0090] During specific use, through the arrangement of the connecting rod 42, the support plate 43 supports the connecting rod 42. The first bevel gear 4 and the second bevel gear 41 are meshed with each other. Under the action of the second crushing roller 14, the connecting rod 42 rotates along with the first bevel gear 4 and the second bevel gear 41. By adopting a linkage method, the energy consumption is relatively low.

[0091] Please refer to Figure 2 and Figure 5 In this embodiment, a first rotating rod 5 is rotatably connected to the middle of the inner bottom wall of the housing 1. A fan blade 51 is fixedly connected to the top of the outer surface of the first rotating rod 5. The first rotating rod 5 penetrates through the housing 1. Both the first rotating rod 5 and the connecting rod 42 protrude from the lower surface of the housing 1.

[0092] During specific use, through the arrangement of the fan blade 51, the first rotating rod 5 rotates along with the connecting rod 42 under the action of the synchronous pulley 6 and the synchronous belt 61, so that the fan blade 51 rotates, blows the ground polygonatum odoratum raw material particles, makes the mutual movement between the raw material particles more sufficient, and the drying more uniform, greatly improving the efficiency of subsequent extraction.

[0093] Please refer to Figure 2 and Figure 5 In this embodiment, synchronous pulleys 6 are fixedly connected to the bottoms of the outer surfaces of the connecting rod 42 and the first rotating rod 5. The inner sides of the synchronous pulleys 6 are drivingly connected with a synchronous belt 61. A tension pulley 62 is slidably connected to the middle of the inner side of the synchronous belt 61. The tension pulley 62 is rotatably connected to the housing 1.

[0094] During specific use, through the arrangement of the synchronous pulley 6 and the synchronous belt 61, they cooperate with each other, enabling the connecting rod 42 to drive the first rotating rod 5 to rotate, providing power support for the rotation of the fan blade 51. The tension pulley 62 can prevent the synchronous belt 61 from slipping during use, ensuring the stability of the device during operation.

[0095] Please refer to Figure 1 In this embodiment, a feed hopper 7 is fixedly connected to the upper surface of the housing 1. A discharge channel 71 is fixedly connected to the bottom of the outer surface of the housing 1.

[0096] During specific use, through the arrangement of the feed hopper 7 and the discharge channel 71, the opening on the surface of the feed hopper 7 gradually narrows from top to bottom, facilitating the transportation of polygonatum odoratum raw materials. The discharge channel 71 facilitates the discharge of the pretreated raw materials to the outside and is convenient for receiving.

[0097] Please refer to Figure 3 In this embodiment, a flow guide plate 8 is fixedly connected to the inner bottom wall of the housing 1. Card slots 81 are formed on both sides of the inner side surface of the discharge channel 71, and a baffle 82 is clamped to the inner side surface of the card slot 81.

[0098] During specific use, due to the arrangement of the flow guide plate 8 which is of an inclined structure, the pre-treated polygonatum odoratum raw materials inside the housing 1 can be better transported to the outside, reducing internal residues. Move the baffle 82 upward inside the card slot 81 to open the discharge channel 71, and the pre-treated polygonatum odoratum raw materials can be discharged to the outside. Close the baffle 82 to prevent the polygonatum odoratum raw materials from floating out of the device during processing.

[0099] Please refer to Figure 1 and Figure 6 In this embodiment, a water tank 9 is fixed to the bottom of the outer surface of the housing 1 on the side far from the discharge channel 71; a drain pipe 91 is fixed to the bottom of the outer surface of the water tank 9; a fixing seat 92 is fixed to the middle of the inner bottom wall of the water tank 9; a conveying cylinder 10 is fixed to the upper surface of the fixing seat 92; and drainage holes 101 are uniformly formed on the outer surface of the conveying cylinder 10 in a circumferential array.

[0100] During specific use, the water tank 9 supports the conveying cylinder 10 through the fixing seat 92. The conveying cylinder 10 is used for transporting the washed polygonatum odoratum. During the transportation process, the residual water on the surface of the polygonatum odoratum is discharged through the multiple drainage holes 101 on the surface of the conveying cylinder 10, which can significantly reduce the initial water content of the raw materials. In this way, the subsequent drying process will be more efficient and the drying time can be greatly shortened. The water discharged is received by the water tank 9, and the drain pipe 91 discharges the received water to a designated location. These waters can be used again for the cleaning process of polygonatum odoratum after simple filtration and treatment, realizing the recycling of water resources.

[0101] Please refer to Figure 1 、 Figure 6 and Figure 7, in this embodiment, the second motor 102 is fixed to the lower surface of the conveying cylinder 10. The output end of the second motor 102 is fixedly connected to a second rotating rod 103, and a screw conveyor blade 104 is fixedly connected to the outer surface of the second rotating rod 103; a crank 105 is fixed to the top of the outer surface of the second rotating rod 103. One side of the upper surface of the crank 105 away from the second rotating rod 103 is rotatably connected to a connecting arm 106. One side of the lower surface of the connecting arm 106 away from the crank 105 is rotatably connected to a support rod 107, and a rocker 108 is fixedly connected to the lower surface of the support rod 107; a discharge pipe 109 is fixed to the top of the outer surface of the conveying cylinder 10, and the discharge pipe 109 is rotatably connected to one side of the lower surface of the rocker 108; a corrugated pipe 110 is fixed to one end of the discharge pipe 109, and the corrugated pipe 110 is fixedly connected to the other side of the lower surface of the rocker 108.

[0102] During specific use, the second motor 102 drives the second rotating rod 103 to rotate, so that the screw conveyor blade 104 conveys the cleaned polygonatum odoratum raw materials, realizing continuous conveyance of the raw materials, enabling the polygonatum odoratum raw materials to continuously enter the subsequent processing links, thereby improving production efficiency and realizing continuous production. At the same time, during the conveyance process, the polygonatum odoratum raw materials are continuously tumbled, which can better reduce the moisture remaining on the surface of the polygonatum odoratum raw materials. One side of the crank 105 is connected to the top of the second rotating rod 103, and the other side is rotatably connected to the connecting arm 106. The side of the connecting arm 106 away from the crank 105 is connected to the rocker 108 through the support rod 107. Both sides of the lower surface of the rocker 108 are respectively connected to the discharge pipe 109 and the corrugated pipe 110. The corrugated pipe 110 can better adapt to the swing changes. When the second rotating rod 103 rotates, the crank 105 rotates accordingly, driving the rocker 108 to rotate and swing with one side of the discharge pipe 109 as the center through the connecting arm 106 and the support rod 107, so that the other side of the rocker 108 drives the corrugated pipe 110 to perform regular reciprocating swings, making the polygonatum odoratum raw materials more evenly distributed on the feed hopper 7 during the conveyance process, helping to improve the conveyance efficiency, avoiding material accumulation or blockage, and ensuring that the raw materials can smoothly enter the subsequent processing links.

[0103] Working principle: During use, the second motor 102 drives the second rotating rod 103 to rotate, so that the auger conveying blade 104 conveys the cleaned polygonatum odoratum raw materials. During the conveying process, the polygonatum odoratum raw materials are tumbled, and the residual moisture on the surface of the polygonatum odoratum is discharged through multiple drain holes 101 on the surface of the conveying cylinder 10, reducing the initial moisture content of the raw materials. The water tank 9 receives the discharged water, and the drain pipe 91 discharges the received water to a designated location, realizing the recycling of water resources. When the second rotating rod 103 rotates, the bellows 110 performs regular reciprocating swings through the reciprocating swing mechanism, so that the polygonatum odoratum raw materials are more evenly distributed on the feed hopper 7 during the conveying process. The first motor 12 drives the first crushing roller 13 to rotate. Under the action of two groups of gears 15, the first crushing roller 13 and the second crushing roller 14 rotate relatively to perform preliminary crushing on the polygonatum odoratum raw materials. The preliminarily crushed polygonatum odoratum raw materials slide downwards. The small transmission wheel 16 drives the large transmission wheel 18 to rotate through the belt 17, so that two groups of grinding rollers 19 rotate relatively to perform grinding treatment on the preliminarily crushed polygonatum odoratum raw materials. The scraping seat 2 scrapes the raw materials remaining on the surface of the grinding roller 19, and the cleaning brush 21 cleans the crushed raw materials remaining on the surfaces of the first crushing roller 13 and the second crushing roller 14 to avoid waste of raw materials. The heating plate 3 can heat the lower half space of the housing 1. The connecting rod 42 rotates with the first crushing roller 13 through the first conical tooth 4 and the second conical tooth 41. The synchronous wheel 6 and the synchronous belt 61 enable the connecting rod 42 to drive the first rotating rod 5 to rotate, so that the fan blade 51 rotates to blow the ground polygonatum odoratum raw material particles, making the drying more uniform. Move the baffle 82 upwards to open the discharge channel 71. The guide plate 8 enables the pretreated polygonatum odoratum raw materials inside the housing 1 to be better conveyed to the outside, reducing internal residues.
