Description

Technical Field

[0001] This utility model relates to the technical field of Polygonatum processing, specifically to a Polygonatum production and pulverizing device. Background Technology

[0002] Polygonatum is a perennial herb and also a medicinal and edible plant. Its stem is rhizome-like; the nodes are swollen, thicker at one end and thinner at the other, with short branches at the thicker end. Polygonatum can be used directly as medicine.

[0003] Chinese patent CN219519054U discloses a production equipment for instant Polygonatum sibiricum powder, including a mounting frame. A crushing box is fixedly connected to the top of the mounting frame. A crushing assembly for crushing Polygonatum sibiricum is arranged inside the crushing box. A driving mechanism is arranged at the bottom of the crushing box. The crushing assembly includes two crushing rollers. A support frame is arranged in the middle of the two crushing rollers. Two mounting plates are fixedly connected to both sides of the support frame. The mounting plates are staggered with the crushing rollers. A cleaning brush is fixedly connected to the lower surface of the mounting plates.

[0004] In the above solution, the accumulation of Polygonatum is avoided by the cooperation of the support frame, mounting plate and cleaning brush. However, this solution has the following disadvantages: Although the cleaning brush can guide the Polygonatum powder at the bottom of the crushing box and prevent it from accumulating, the Polygonatum raw material will adhere to the outer wall of the crushing roller as it rotates. If the Polygonatum raw material is not removed for a long time, it will easily increase the working load of the crushing roller. Utility Model Content

[0005] The purpose of this invention is to provide a pulverizing device for the production of Polygonatum odoratum, in order to solve the problem that although the cleaning brush can guide the Polygonatum odoratum powder at the bottom of the pulverizing box and prevent it from accumulating, the Polygonatum odoratum raw material will adhere to its outer wall as the pulverizing roller rotates during the pulverizing process. If the Polygonatum odoratum raw material is not removed for a long time, it will easily increase the working load of the pulverizing roller.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a pulverizing device for producing Polygonatum sibiricum, comprising a protective cover, the protective cover being disposed above a housing, the top surface of the protective cover having several through holes, a connecting post being inserted into the inner wall of the through holes, a spring being wound around the outer wall of the connecting post, the top end of the spring being connected to the bottom surface of the protective cover, a mounting frame being fixed to the bottom end of the connecting post, the bottom end of the spring being connected to the top surface of the mounting frame, two connecting plates being disposed on the inner wall of the mounting frame, a cleaning brush being fixed to the bottom surface of the left connecting plate, a first scraper being fixed to the bottom surface of the right connecting plate, a drive motor being fixed to the top surface of the protective cover, a connecting block being fixed to one end of the output shaft of the drive motor, and pressure rollers being rotatably disposed on both sides of the connecting block, the cleaning brush and the first scraper both being in contact with the outer wall of the pressure rollers.

[0007] Preferably, the bottom surface of the connecting block is fixed with an installation strip, the installation strip has two inclined grooves, and the ends of the installation strip are fixed with two second scraper plates, the second scraper plates being in contact with the inner wall of the box.

[0008] Preferably, a mounting bracket is fixed to the top surface of the housing, a cylinder is fixed to the top surface of the mounting bracket, one end of the telescopic rod of the cylinder is fixed to the top surface of the protective cover, and a sealing gasket is fixed to the bottom surface of the protective cover, with the bottom surface of the sealing gasket in contact with the housing.

[0009] Preferably, the top surface of the protective cover is fixed with two limiting posts, and the top surface of the mounting bracket is provided with two limiting holes, with the limiting posts inserted into the limiting holes.

[0010] Preferably, the mounting frame has a plurality of threaded holes, the inner wall of the threaded holes is threaded with bolts, and the connecting plate has a plurality of positioning grooves, the positioning grooves corresponding to the threaded holes, and the bolts are inserted into the positioning grooves.

[0011] Preferably, the left side of the box has a discharge port that is connected to the internal cavity of the box, and the left side of the box is rotatably connected to a baffle plate via a hinge.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated action of the connecting column, spring, mounting frame, connecting plate, cleaning brush, and first scraper, the raw material of Polygonatum adhering to the surface of the pressure roller can be scraped and cleaned, effectively preventing the raw material from adhering to the outer wall of the pressure roller for a long time, increasing its workload, ensuring the stability of equipment operation, thereby reducing waste caused by Polygonatum residue, and thus improving the overall crushing efficiency and raw material utilization rate. The inclined chute guides the raw material of Polygonatum inside the chamber, allowing it to be evenly dispersed under the pressure roller, avoiding uneven crushing caused by local accumulation of raw material, and improving the consistency of Polygonatum pulverized particles. The second scraper continuously contacts the inner wall of the chamber, scraping off the Polygonatum powder adhering to the inner wall in real time during equipment operation, thus avoiding waste caused by raw material residue.

[0014] Second, the sealing gasket increases the airtightness between the protective cover and the chamber, effectively isolating the inside and outside of the chamber from air, preventing external dust from entering and contaminating the Polygonatum sibiricum raw material, and reducing dust generation during the Polygonatum sibiricum crushing process, thus protecting the effective components of Polygonatum sibiricum from the influence of the external environment. The synergistic action of the limiting post and limiting hole restricts the movement direction of the protective cover under cylinder drive, preventing offset and shaking during the up-and-down movement of the protective cover, and ensuring the seal alignment between the protective cover and the chamber.

[0015] Third, the synergistic action of bolts, threaded holes, and positioning grooves facilitates quick disassembly or installation of the connecting plate. When the cleaning brush and the first scraper plate need replacement due to wear, it is not necessary to disassemble the entire mounting frame, thereby shortening maintenance time and reducing equipment maintenance costs. The discharge port directly connects to the internal cavity of the housing, allowing the pulverized Polygonatum powder to be quickly discharged through the discharge port under the action of the second scraper plate without opening the protective cover, thus simplifying the discharge process and improving the overall efficiency of Polygonatum pulverization.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a pulverizing device for producing Polygonatum sibiricum includes a protective cover 1, which is positioned above a housing 2. The top surface of the protective cover 1 has several through holes 3. Connecting posts 4 are inserted into the inner walls of the through holes 3. Springs 5 ​​are wound around the outer walls of the connecting posts 4. The top of the springs 5 ​​is connected to the bottom surface of the protective cover 1. A mounting frame 6 is fixed to the bottom end of the connecting posts 4, and the bottom end of the springs 5 ​​is connected to the top surface of the mounting frame 6. Two connecting plates 7 are provided on the inner wall of the mounting frame 6. A cleaning brush 8 is fixed to the bottom surface of the left connecting plate 7, and a first... A drive motor 10 is fixed to the top surface of the scraper 9 and the protective cover 1. A connecting block 11 is fixed to one end of the output shaft of the drive motor 10. A pressure roller 12 is rotatably mounted on both the left and right sides of the connecting block 11. The cleaning brush 8 and the first scraper 9 are in contact with the outer wall of the pressure roller 12. An installation strip 13 is fixed to the bottom surface of the connecting block 11. Two inclined grooves 14 are opened on the installation strip 13. Two second scraper 15s are fixed to the ends of the installation strip 13. The second scraper 15s are in contact with the inner wall of the box 2. The positions of the two sets of cleaning brushes 8 and the first scraper 9 are opposite.

[0023] In use, when crushing Polygonatum, the operator first puts the raw material to be crushed into the cavity inside the box 2 evenly, then starts the cylinder 17. The cylinder 17 drives the protective cover 1 to descend vertically along the guide post 19 until the sealing gasket 18 at the bottom of the protective cover 1 is completely in contact with the top surface of the box 2, thus sealing the inside of the box 2. During this process, the spring 5 on the outer wall of the connecting post 4 is compressed and contracts, driving the mounting frame 6 to descend synchronously, so that the cleaning brush 8 and the first scraper 9 are tightly in contact with the outer wall of the pressure roller 12. Then the cylinder 17 is closed to complete the equipment closure.

[0024] At this time, the drive motor 10 can be started. The output shaft of the drive motor 10 drives the connecting block 11 to rotate counterclockwise, thereby driving the two pressure rollers 12 to rotate synchronously along the inner wall of the box 2. The pressure rollers 12 circulate and crush the Polygonatum raw material on the bottom surface of the box 2 to achieve the preset crushing particle size. During the rotation of the pressure rollers 12, the first scraper 9 scrapes off the Polygonatum raw material residue attached to the surface of the pressure rollers 12 in real time. The cleaning brush 8 further cleans the outer wall of the pressure rollers 12, effectively avoiding the decrease in crushing efficiency and cross-contamination caused by raw material residue. At the same time, the inclined groove 14 on the mounting strip 13 guides and diverts the Polygonatum raw material in the box 2 to ensure that the raw material is evenly distributed under the pressure rollers 12, preventing uneven crushing particle size caused by local accumulation and ensuring the consistency of Polygonatum crushed particles.

[0025] After the raw material of Polygonatum is crushed, the operator opens the baffle plate 25 on the left side of the box 2. Under the guiding effect of the installation strip 13 and the scraping effect of the second scraper 15 on the residual powder on the inner wall of the box 2, the Polygonatum powder in the box 2 is concentrated and guided to the discharge port 24. The operator collects the Polygonatum powder through the discharge port 24 to complete the crushing operation.

[0026] Through the coordinated action of connecting column 4, spring 5, mounting frame 6, connecting plate 7, cleaning brush 8, and first scraper 9, the raw material of Polygonatum adhering to the surface of pressure roller 12 can be scraped and cleaned, effectively preventing the raw material of Polygonatum from adhering to the outer wall of pressure roller 12 for a long time, increasing its workload, ensuring the stability of equipment operation, thereby reducing waste caused by Polygonatum residue, and thus improving the overall crushing efficiency and raw material utilization rate. The inclined groove 14 can guide the raw material of Polygonatum in the box 2, so that the raw material can be evenly dispersed under pressure roller 12, avoiding uneven crushing caused by local accumulation of raw material, and improving the consistency of Polygonatum crushed particles. Through the continuous contact between the second scraper 15 and the inner wall of the box 2, the Polygonatum powder adhering to the inner wall of the box 2 can be scraped off in real time during equipment operation, thus avoiding waste caused by raw material residue.

[0027] like Figures 1-4 As shown, a mounting bracket 16 is fixed on the top surface of the box 2, and a cylinder 17 is fixed on the top surface of the mounting bracket 16. One end of the telescopic rod of the cylinder 17 is fixed to the top surface of the protective cover 1. A sealing gasket 18 is fixed on the bottom surface of the protective cover 1, and the bottom surface of the sealing gasket 18 is in contact with the box 2. Two limiting posts 19 are fixed on the top surface of the protective cover 1. Two limiting holes 20 are opened on the top surface of the mounting bracket 16. The limiting posts 19 are inserted into the limiting holes 20. Several threaded holes 21 are opened on the mounting frame 6. Bolts 22 are threadedly connected to the inner wall of the threaded holes 21. Several positioning grooves 23 are opened on the connecting plate 7. The positioning grooves 23 correspond to the threaded holes 21. Bolts 22 are inserted into the positioning grooves 23. A discharge port 24 is opened on the left side of the box 2. The discharge port 24 is connected to the internal cavity of the box 2. A baffle plate 25 is rotatably connected to the left side of the box 2 via a hinge.

[0028] During use, the sealing gasket 18 increases the airtightness between the protective cover 1 and the box 2, effectively isolating the air inside and outside the box 2, preventing external dust from entering and contaminating the Polygonatum sibiricum raw material, and reducing dust generation during the Polygonatum sibiricum crushing process, thus protecting the effective components of Polygonatum sibiricum from the influence of the external environment. The synergistic action of the limiting post 19 and the limiting hole 20 restricts the movement direction of the protective cover 1 under the drive of the cylinder 17, preventing offset and shaking when the protective cover 1 moves up and down, and ensuring the sealed alignment of the protective cover 1 and the box 2.

[0029] The synergistic action of bolts 22, threaded holes 21, and positioning grooves 23 facilitates quick disassembly or installation of the connecting plate 7. When the cleaning brush 8 and the first scraper 9 need to be replaced due to wear, it is not necessary to disassemble the entire mounting frame 6, thereby shortening maintenance time and reducing equipment maintenance costs. The discharge port 24 directly connects to the internal cavity of the housing 2, allowing the pulverized Polygonatum powder to be quickly discharged through the discharge port 24 under the action of the second scraper 15 without opening the protective cover 1, thus simplifying the discharge process and improving the overall efficiency of Polygonatum pulverization.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
