Description

Technical Field

[0001] This invention relates to the field of ginseng processing technology, and more specifically to a ball mill for ginseng processing. Background Technology

[0002] American ginseng is a precious traditional Chinese medicine. Traditional Chinese medicine believes that American ginseng is cool in nature, sweet and slightly bitter in taste, and can replenish qi and nourish yin, clear heat and promote body fluid production. It is mainly used to treat symptoms such as qi and yin deficiency, internal heat, cough and asthma. Modern medical research also shows that American ginseng has various pharmacological effects, such as protecting the cardiovascular system, enhancing the function of the central nervous system, and improving immunity. However, the active ingredients in American ginseng are often encased in a hard fibrous structure, making it difficult to expose and extract them. Therefore, a ball mill is needed. Through the grinding action of the ball mill, American ginseng can be ground into powder. After being ground by the ball mill, the cell structure of the ginseng powder is destroyed, making it easier for solvents to penetrate and dissolve the active ingredients. This is extremely beneficial for subsequent extraction, separation, and formulation processes, and can significantly improve the extraction efficiency of the active ingredients.

[0003] Most ball mills currently on the market adopt a horizontal structure. When the ball mill is working, the rotation of the cylinder drives the American ginseng and grinding steel balls inside to tumble and rise. After rising to a certain height, the grinding steel balls fall and impact the American ginseng, thereby crushing and grinding it. However, the overall structure is large and not easy to disassemble and assemble, making it difficult to maintain the internal parts. Moreover, American ginseng often adheres to the surface of the grinding steel balls after grinding, which is not easy to clean. This affects the overall grinding efficiency and product quality, and is quite inconvenient. Summary of the Invention

[0004] Therefore, the present invention provides a ball mill for ginseng processing to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A magnetic sheet is provided on the outer side of the support ring plate. A fixing frame is fixedly installed on the inner wall of the upper outer shell by screws, and an electromagnetic block is embedded in the end of the fixing frame near the central axis of the upper outer shell.

[0010] The mounting bracket is fixed to the inside of the lower outer shell by screws, and a screen is embedded inside the mounting bracket. A connecting cylinder is installed through the middle of the mounting bracket. A discharge pipe is provided at the lower middle of the lower outer shell. A fan is installed on the outer side of the right wall of the upper outer shell, and a connecting ring pipe located inside the upper outer shell is connected to the outer side of the left end of the fan. A connecting pipe is connected to the lower end of the connecting ring pipe, and an air blowing nozzle is provided on the outer side of the lower end of the connecting pipe.

[0011] Furthermore, a first positioning block is integrally fixedly installed on the upper outer side of the conveying screw, and a transmission gear located inside the positioning plate is engaged with the outer side of the first positioning block, and the transmission gear is connected to the positioning plate by rotation.

[0012] Furthermore, the top cover has connecting tooth blocks that are adapted to the transmission gear fixedly installed at equal angles inside, and the transmission gear and the connecting tooth blocks are connected by meshing. The lower end of the top cover extends into the interior of the upper outer shell.

[0013] Furthermore, the top cover has inlets through the interior of both the left and right sides, and a guide plate is fixedly installed on the upper inner side of the top cover, with the upper end of the guide plate being inclined.

[0014] Furthermore, a second positioning block is installed inside the lower end of the top cover, which corresponds one-to-one with the connecting ear, and the upper end of the second positioning block is connected to a spring located inside the top cover, and the second positioning block forms a telescopic structure inside the top cover through the spring.

[0015] Furthermore, the outer mounting block, the inner mounting block, and the connecting cylinder are connected at their middle ends, and the lower end of the inner mounting block has a pre-fabricated arc-shaped through groove, the diameter of which decreases from the outside to the inside.

[0016] Furthermore, the upper end of the outer mounting block is connected to the positioning plate by a snap-fit ​​method, and the upper end of the side wall of the outer mounting block is provided with a discharge port, and the upper end of the middle part of the inner mounting block extends to the upper end of the inner side of the outer mounting block and contacts each other.

[0017] Furthermore, a limiting plate is fixedly installed at an equal angle on the lower outer side of the outer mounting block, and the limiting plate is connected to the inner mounting block by plugging. The grinding liner embedded inside the outer side of the outer mounting block has through holes at equal intervals on its inner side.

[0018] Furthermore, the lower end of the connecting cylinder has an inlet, and the lower end of the conveying screw extends into the interior of the connecting cylinder, while the upper end of the connecting cylinder is connected to the lower middle part of the inner mounting block.

[0019] Furthermore, the tilt angle of the air blowing nozzle is adapted to the tilt angle of the screen, and the screen is located directly below the prefabricated through groove.

[0020] The present invention has the following advantages:

[0021] 1. The system consists of a lower outer shell, an upper outer shell, and a top cover. The upper outer shell is installed on the upper outer side of the lower outer shell with screws, and the top cover is installed on the upper end of the upper outer shell with a limiting block and fixing bolts. During installation, it is convenient to assemble and disassemble the upper outer shell and the top cover in sequence, which facilitates daily maintenance of the internal components of the lower outer shell, the upper outer shell, and the top cover.

[0022] 2. Through the support ring plate and the air nozzle, the electromagnetic block magnetically attracts the magnetic sheet. At this time, the magnetic sheet drives the support ring plate to open under the action of the electromagnetic block, so that the gap between the support ring plate and the grinding liner is larger than the diameter of the grinding steel ball, allowing the grinding steel ball to fall onto the screen. At the same time, the blower transmits outside air through the connecting ring pipe and the connecting pipe to the air nozzle, and sprays it out through the air nozzle to clean the grinding steel ball, making it easier to remove the ginseng powder adhering to its surface. The blades of the conveying screw are equipped with convex strips, which allow the grinding steel ball to move upward under the action of the conveying screw and move again from the discharge port to the inside of the top cover, achieving effective self-cleaning of the grinding steel ball and improving the convenience of use.

[0023] 3. Through the transmission gear and connecting tooth block, the drive motor drives the conveying screw to rotate. At the same time, the conveying screw rotates and drives the transmission gear to rotate inside the positioning plate through the first positioning block. At this time, the transmission gear and the connecting tooth block mesh and connect, thereby driving the top cover to rotate inside the upper outer shell and the positioning plate, which in turn facilitates the grinding steel ball to roll outside the grinding liner, making it convenient for subsequent grinding of American ginseng.

Detailed Implementation

[0034] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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] Example 1

[0036] like Figures 1 to 9 As shown, a ball mill for processing ginseng according to a first aspect embodiment of the present invention includes: a lower outer shell 1 with support legs 35 fixedly installed on both the left and right sides of its lower end for easy support of the whole; an upper outer shell 2 fixedly installed on the upper outer side of the lower outer shell 1 by screws, and a top cover 3 connected to the upper outer side of the upper outer shell 2; a positioning plate 4 is installed through the middle of the top cover 3; a limit block 12 is slidably installed inside the top of the upper outer shell 2; and a fixing bolt 13 is provided at the connection between the top cover 3 and the limit block 12 for easy sequential feeding. The upper outer shell 2 and the top cover 3 are spliced ​​and installed. When the top cover 3 is installed, it is snapped onto the upper outer side of the limiting block 12. The upper outer shell 2 and the top cover 3 are then fixed by screws and fixing bolts 13, which facilitates installation. Similarly, it is easy to disassemble, which facilitates daily maintenance of the internal components of the lower outer shell 1, the upper outer shell 2 and the top cover 3. The longitudinal section of the limiting block 12 is set in a "T" shape, which can effectively prevent the limiting block 12 from separating from the upper outer shell 2 when sliding, thus ensuring the stability of the top cover 3 when rotating.

[0037] The inner mounting block 14 is fixedly installed on the inner end of the upper outer shell 2, and an outer mounting block 15 is connected to the outer side of the inner mounting block 14. The upper end of the outer mounting block 15 is connected to the positioning plate 4 by a snap-fit ​​method, and the upper middle part of the inner mounting block 14 extends to the upper inner part of the outer mounting block 15 and contacts each other. Before installing the top cover 3, the outer mounting block 15 is installed on the upper outer side of the inner mounting block 14, so that the upper inner part of the outer mounting block 15 contacts the upper part of the inner mounting block 14. A limiting plate 18 is fixedly installed at an equal angle on the lower outer side of the outer mounting block 15, and the limiting plate 18 is connected to the inner mounting block 14 by a plug-in connection. The limiting plate 18 plays a good positioning role for the outer mounting block 15, which improves the installation effect. Then, the top cover 3 and the positioning plate 4 are installed. The positioning plate 4 is installed on the upper outer side of the outer mounting block 15, so that the positioning plate 4 matches the groove opened in the upper inner part of the outer mounting block 15, which improves the installation effect of the positioning plate 4 and prevents it from moving.

[0038] The lower end of the top cover 3 extends into the interior of the upper outer shell 2. The left and right sides of the top cover 3 are provided with feed inlets 11. A guide plate 10 is fixedly installed on the upper inner side of the top cover 3. The upper end of the guide plate 10 is inclined. A grinding liner 16 is embedded in the outer side of the outer mounting block 15. The grinding liner 16 is inclined. A grinding steel ball 20 is located on the outer side of the grinding liner 16 at the lower inner side of the top cover 3. Before grinding, the grinding steel ball 20 is placed into the inner side of the top cover 3 through the feed inlet 11 and the guide plate 10. The grinding steel ball 20 is located on the outer side of the grinding liner 16. At the same time, the distance between the lower end of the support ring plate 22 and the grinding liner 16 is smaller than the diameter of the grinding steel ball 20, which can block the grinding steel ball 20 and prevent the grinding steel ball 20 from falling.

[0039] A drive motor 5 is installed at the upper center of the positioning plate 4, and the output end of the drive motor 5 is connected to a conveying screw rod 6. A first positioning block 7 is integrally fixedly installed on the upper outer side of the conveying screw rod 6, and a transmission gear 8 located inside the positioning plate 4 is engaged with the outer side of the first positioning block 7. The transmission gear 8 is rotatably connected to the positioning plate 4, which facilitates the rotation of the transmission gear 8 by the conveying screw rod 6 and the first positioning block 7. A connecting tooth block 9 adapted to the transmission gear 8 is fixedly installed at equal angles inside the top cover 3, and the transmission gear 8 and the connecting tooth block 9 are... The components are connected by meshing. When the drive motor 5 is started, it drives the conveying screw 6 to rotate. As the conveying screw 6 rotates, it drives the transmission gear 8 to rotate inside the positioning plate 4 through the first positioning block 7. At this time, the transmission gear 8 meshes with the connecting tooth block 9, thereby driving the top cover 3 to rotate inside the upper outer shell 2 and the positioning plate 4. This facilitates the rolling of the grinding steel ball 20 outside the grinding liner 16. At the same time, the part of the top cover 3 located inside the positioning plate 4 is provided with a protruding structure, which can effectively ensure the connection effect between the top cover 3 and the positioning plate 4.

[0040] The dried American ginseng is added to the top cover 3 through the feed inlet 11, so that the American ginseng comes into contact with the rolling grinding steel balls 20 and the grinding liner 16, thereby grinding the American ginseng. The inner side of the grinding liner 16 has through holes at equal intervals, and the lower end of the inner mounting block 14 has a pre-fabricated arc-shaped through groove 19, and the diameter of the pre-fabricated through groove 19 decreases from the outside to the inside. The mounting bracket 27 is fixedly installed inside the lower outer shell 1 by screws, and the interior of the mounting bracket 27 is inlaid with... A screen 28 is embedded in the pre-made through groove 19. During the grinding process, smaller American ginseng powder can fall through the through hole structure and the pre-made through groove 19, while larger American ginseng powder can fall through the gap between the grinding liner plate 16 and the support ring plate 22 and the pre-made through groove 19, and fall onto the screen 28 respectively. By controlling the falling position of American ginseng powder of different volumes, it is possible to effectively avoid the phenomenon that large American ginseng powder will block the screen 28 and affect the filtration of smaller American ginseng powder.

[0041] The lower end of the conveying screw 6 extends into the interior of the connecting cylinder 29. The upper end of the connecting cylinder 29 is connected to the middle of the lower end of the inner mounting block 14. The lower end of the connecting cylinder 29 has an inlet. The outer mounting block 15, the inner mounting block 14 and the middle of the connecting cylinder 29 are connected. Smaller American ginseng powder can pass through the screen 28 and fall into the lower end of the lower outer shell 1, which is convenient for opening the valve and discharging through the discharge pipe 30. Larger American ginseng powder can move to the inlet of the connecting cylinder 29 under the action of the inclined screen 28, and pass through the connecting cylinder 29, the inner mounting block 14 and the outer mounting block 15 in sequence under the action of the conveying screw 6. It is discharged from the discharge port 17 and then enters the grinding steel ball 20 and the grinding liner 16 for further grinding. The above steps are repeated until the powder volume is ground to the specified coarseness, which improves the overall grinding effect.

[0042] The connecting ear 21 is installed inside the lower end of the top cover 3 via a torsion spring shaft, and a support ring plate 22 is fixedly installed on the outer side of the lower end of the connecting ear 21. A magnetic sheet 23 is provided on the outer end of the support ring plate 22. A fixing bracket 24 is fixedly installed on the inner wall of the upper outer shell 2 by screws, and an electromagnetic block 25 is embedded in the end of the fixing bracket 24 near the central axis of the upper outer shell 2. A second positioning block 26 is installed inside the lower end of the top cover 3, which is arranged in a one-to-one correspondence with the connecting ear 21. The upper end of the second positioning block 26 is connected to a spring located inside the top cover 3, and the second positioning block 26 forms a telescopic structure inside the top cover 3 through the spring. After grinding is completed, the drive motor is turned off. 5. Keep the top cover 3 stationary and activate the electromagnetic block 25 through the control panel. The electromagnetic block 25 magnetically attracts the magnetic sheet 23. At this time, the magnetic sheet 23 drives the support ring plate 22 to open under the action of the electromagnetic block 25, and causes the connecting ear 21 and the torsion spring shaft to rotate. The connecting ear 21 exerts a squeezing force on the second positioning block 26, causing the second positioning block 26 to retract upward and lose its fixing effect on the connecting ear 21. At the same time, the spring and its internal damper are compressed, which can drive the support ring plate 22 to open. At this time, the gap between the support ring plate 22 and the grinding liner 16 is greater than the diameter of the grinding steel ball 20, so that the grinding steel ball 20 can fall onto the screen 28.

[0043] A connecting cylinder 29 is installed through the middle of the mounting frame 27. A discharge pipe 30 is installed at the lower middle of the lower outer shell 1. A blower 31 is installed on the outer side of the right wall of the upper outer shell 2. A connecting ring pipe 32 located inside the upper outer shell 2 is connected to the outer side of the left end of the blower 31. A connecting pipe 33 is connected to the lower end of the connecting ring pipe 32. An air blowing nozzle 34 is installed on the outer side of the lower end of the connecting pipe 33. The tilt angle of the air blowing nozzle 34 is adapted to the tilt angle of the screen 28. The blower 31 is started through the control panel, so that the blower 31 transmits outside air through the connecting ring pipe 32 and the connecting pipe 33 to the air blowing nozzle 34. The air is sprayed out through the air nozzle 34 to clean the grinding steel balls 20, making it easier to remove the ginseng powder adhering to their surface. Then, the electromagnetic block 25 is closed and the drive motor 5 is started, so that the support ring plate 22 returns to its original position under the action of the torsion spring shaft and is fixed by the second positioning block 26. At the same time, the blades of the conveying screw rod 6 are provided with convex strips, so that the grinding steel balls 20 can move upward under the action of the conveying screw rod 6 and move again from the discharge port 17 to the inside of the top cover 3, realizing effective self-cleaning of the grinding steel balls 20 and improving the convenience of use.
