Description

Technical Field

[0001] The invention relates to the field of traditional Chinese medicine processing, in particular to a rhizome traditional Chinese medicine pulverizer. Background Art

[0002] Traditional crushing mechanisms, such as ball mills and universal crushers, mostly use impact, grinding and other methods. It is difficult to achieve uniform crushing for rhizomes of Chinese medicine with irregular shapes and uneven textures, which often leads to large differences in the particle size of the crushed products, affecting the quality stability of subsequent preparations. And because rhizomes of Chinese medicine often contain rich fibrous tissue, when directly chopped, the cutter may simply cut the rhizomes of Chinese medicine into blocks, and the fibrous tissue may not be fully cut off, and there are still long fiber bundles connected, which will affect subsequent processing. For example, when extracting active ingredients, the active ingredients are difficult to fully dissolve. In addition, these fiber bundles are easy to entangle on the crushing parts or clog in the corners of the crushing chamber during the crushing process, resulting in poor operation of the equipment, and even frequent shutdowns for cleaning, reducing production efficiency.

[0003] At the same time, some rhizomes of Chinese medicine have high hardness, such as Pueraria lobata and Astragalus membranaceus. When traditional crushing equipment handles these materials, it may be difficult to effectively crush them due to insufficient impact force or low grinding efficiency, which increases the processing difficulty and cost. Secondly, the hardness and toughness of rhizomes of Chinese medicine cause great wear on the cutting tools. In the direct chopping process, the contact between the cutting tools and rhizomes of Chinese medicine is more concentrated and intense, which can easily lead to rapid wear of the cutting edge of the cutting tools, requiring frequent replacement of the cutting tools, increasing the maintenance cost and downtime of the equipment. In addition, traditional crushing methods are often accompanied by higher temperatures, especially during grinding and impact, which can easily destroy the heat-sensitive active ingredients in Chinese medicine, reducing the efficacy and quality of Chinese medicine.

Second, the steel needle in the device adopts a telescopic structure. The lower sliding plate will move according to the direction of rotation of the bottom cylinder to realize the extension and recovery of the steel needle, and the upper sliding plate will drive the steel needle to pass through the upper plate when the bottom cylinder is close to the top cylinder, and drive the steel needle to be recovered when the bottom cylinder is away from the top cylinder. This process can prevent the fiber tissue of rhizome Chinese medicine from adhering to the steel needle, ensuring that the crushing process can proceed smoothly; Third: Compared with traditional crushing devices, the shredding processing method adopted by this device is relatively gentle, generates less heat, can effectively prevent heat-sensitive active ingredients from being destroyed by high temperature, and retain the efficacy and quality of rhizome Chinese medicines to the greatest extent. At the same time, when the bottom cylinder is constantly rotating forward and reverse, the rhizome Chinese medicines will be fully stirred and mixed in the crushing area. When the steel needle is extended, the rhizome Chinese medicines are crushed, and when the steel needle is retracted, the rhizome Chinese medicines are redistributed and adjusted, so that the rhizome Chinese medicines are constantly turned and displaced during the crushing process, so that the crushing is more uniform and a product with more consistent particle size is obtained.

[0018] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] refer to Figures 1 to 9 , a root and rhizome Chinese medicine pulverizer, comprising a base 1, and also comprising: The crushing mechanism 16 is connected to the base 1 and includes a top cylinder 21, a top plate 19, an upper plate 17, an upper sliding plate 18, a lower plate 29, a lower sliding plate 31, a bottom cylinder 30, a plurality of steel needles 28 and a plurality of bidirectional crushing mechanisms 36. The top cylinder 21 is fixedly connected to the top of the base 1, and the upper plate 17 is fixedly connected to the lower end of the top cylinder 21 (such as Figure 5 As shown in the figure, the top plate 19 is arranged above the upper plate 17 and is slidably connected to the top cylinder 21, the upper sliding plate 18 is arranged above the upper plate 17 on a side close to the top plate 19 and is slidably connected to the top cylinder 21, the bottom cylinder 30 is slidably arranged below the top cylinder 21, the lower sliding plate 31 is slidably arranged in the middle of the bottom cylinder 30, the lower plate 29 is arranged above the lower sliding plate 31 and is fixedly connected to the bottom cylinder 30, and a plurality of steel needles 28 are arranged in an array at equal angles to one end of the upper sliding plate 18 and the lower sliding plate 31 (reference Fig. 9 ), the steel needles 28 on the upper sliding plate 18 and the lower sliding plate 31 are arranged alternately, and a plurality of bidirectional crushing mechanisms 36 are arranged in an array at equal angles along the circumferential direction of the lower end of the lower sliding plate 31; The power mechanism 2 is arranged below the bottom cylinder 30, and includes a lifting plate 8 and a rotating plate 15. The rotating plate 15 is coaxially connected to the lower end of the bottom cylinder 30 (refer to Fig. 9 ), the lifting plate 8 is connected to the lower end of the rotating plate 15 coaxially and rotationally.

[0020] When the device is in operation, the rhizome Chinese medicine is placed on the upper end of the lower plate 29, and then the power mechanism 2 is started and drives the bottom cylinder 30 to move toward the top cylinder 21. During the processing, the power mechanism 2 will drive the bottom cylinder 30 to move in the vertical direction through the lifting plate 8, and the rotating plate 15 is used to drive the bottom cylinder 30 to rotate. The specific transmission process is described in detail later.

[0021] After the bottom cylinder 30 approaches the top cylinder 21, the upper sliding plate 18 drives a plurality of steel needles 28 to extend downward through the upper plate 17, and the rotating plate 15 drives the bottom cylinder 30 to rotate, and the rotation direction at this time is specified to be forward rotation, refer to Figure 6 At this time, the bottom cylinder 30 rotates clockwise (clockwise here means looking down at the bottom cylinder 30 from above); the lower sliding plate 31 drives the plurality of steel needles 28 to extend upward through the lower plate 29, and the rhizome Chinese medicine located at the upper end of the lower plate 29 will be pierced by the plurality of steel needles 28 arranged in an alternating manner. Then, when the bottom cylinder 30 rotates, the plurality of steel needles 28 passing through the lower plate 29 and the upper plate 17 will crush the rhizome Chinese medicine during the rotation process, and this crushing process is more suitable for tearing the rhizome Chinese medicine, which is beneficial to reduce the damage to the effective ingredients in the rhizome Chinese medicine. When the rotating disk 15 drives the bottom cylinder 30 to reverse, the lower sliding disk 31 will drive the steel needles 28 to move downward. At this time, the rhizome Chinese medicine located at the upper end of the lower disk 29 is only pierced by the steel needles 28 of the upper disk 17. Then, due to the continuous rotation of the lower disk 29, the rhizome Chinese medicine at the upper end of the lower disk 29 will be redistributed during the rotation process, which is convenient for the subsequent continuous piercing by the steel needles 28 extending out of the lower disk 29, thereby improving the crushing efficiency.

[0022] In order to realize the reciprocating movement of the top plate 19, the following features are also specifically provided: The crushing mechanism 16 further includes a return spring 20, which is disposed above the top plate 19 (see Figure 5 ), the upper end of the return spring 20 is fixedly connected to the top tube 21, and the lower end is fixedly connected to the top plate 19. When the top plate 19 moves upward (the specific movement process will be described in detail later), the return spring 20 will be compressed, so that the return spring 20 that recovers the deformation will push the top plate 19 to move downward and reset.

[0023] In order to enable the upper sliding plate 18 to move toward the upper plate 17 when the lower plate 29 moves toward the upper plate 17, so that the upper sliding plate 18 drives the plurality of steel needles 28 to pass through the upper plate 17 and extend downward, the following features are also specifically provided: The crushing mechanism 16 also includes a central column 22, a guide column 23, a plurality of pressing racks 24, a plurality of transfer gears 25, a plurality of push racks 26 and a plurality of transfer gear seats 27. The central column 22 is coaxially fixedly connected to the lower plate 29 (refer to Figure 5), the guide column 23 is slidably connected with the upper plate 17 coaxially and is fixedly connected to the top plate 19 after passing through the upper sliding plate 18, a plurality of lower pressure racks 24 are arranged in an array at equal angles along the circumferential direction of the lower end of the top plate 19, the lower pressure racks 24 are fixedly connected to the lower end of the top plate 19, and a plurality of transfer gear seats 27 are arranged in an array at equal angles along the circumferential direction below the top plate 19 and are fixedly connected to the inner wall of the top cylinder 21 (reference Figure 8 ), a plurality of transfer gears 25 are rotatably connected to a plurality of transfer gear seats 27 respectively, a plurality of push racks 26 are arranged in an array at equal angles along the circumferential direction of the upper end of the upper sliding plate 18, the push racks 26 are fixedly connected to the upper sliding plate 18, the push racks 26 are meshed with one side of the transfer gear 25, and the pressing racks 24 are meshed with the other side of the transfer gear 25. When the bottom cylinder 30 is close to the top cylinder 21, the center column 22 fixedly connected to the lower plate 29 will push the guide column 23 to move upward, and the guide column 23 will push the top plate 19 to move upward after it moves. At this time, a plurality of pressing racks 24 fixedly connected to the top plate 19 will move upward, and the pressing racks 24 will drive the corresponding push racks 26 to move downward through a plurality of transfer gears 25 after it moves upward, and the push racks 26 will push the upper sliding plate 18 to move downward after it moves downward, and the upper sliding plate 18 will drive a plurality of steel needles 28 to pass through the upper plate 17 downward when it moves downward.

[0024] In order to prepare for the reset of the movement of the lower slide plate 31, the following features are also specifically provided: The crushing mechanism 16 further includes a chassis 32 and a return spring 33. The chassis 32 is disposed below the lower slide plate 31 and is fixedly connected to the bottom of the bottom cylinder 30 (see Fig. 9 ), the upper end of the reset spring 33 is fixedly connected to the lower end of the lower sliding plate 31, and the lower end is fixedly connected to the bottom plate 32. When the lower sliding plate 31 moves upward relative to the bottom tube 30, the lower sliding plate 31 will drive the reset spring 33 fixedly connected thereto to stretch and deform, and when the reset spring 33 recovers its deformation, it will drive the lower sliding plate 31 to move downward and reset.

[0025] In order to drive the bidirectional crushing mechanism 36 to start, the following features are also specifically provided: The crushing mechanism 16 also includes a positioning gear frame 34 and a limiting gear ring 35. The two-way crushing mechanism 36 includes a limiting gear 37. The positioning gear frame 34 is fixedly connected to the middle of the base 1 (refer to Figure 2 ), the limiting gear ring 35 is coaxially connected to the positioning gear frame 34 and is coaxially arranged with the bottom tube 30, and the limiting gear 37 is rotatably arranged on the outside of the bottom tube 30 (refer to Figure 6 ), the limit gear 37 is the input end of the bidirectional crushing mechanism 36. When the power mechanism 2 drives the bottom cylinder 30 to rotate through the rotating disk 15 (the specific rotation process will be described in detail later), the bottom cylinder 30 will drive a number of limit gears 37 to revolve along the circumferential direction of the bottom cylinder 30. During this process, the limit gear ring 35 will drive the limit gear 37 meshing with it to rotate, and the limit gear 37 will drive the bidirectional crushing mechanism 36 to operate when it rotates.

[0026] In order to realize that the output end and the input end of the bidirectional crushing mechanism 36 can transmit and interrupt when the bottom drum 30 rotates in two directions, the following features are also specifically provided: The bidirectional crushing mechanism 36 further includes an active bevel gear 38, a driven bevel gear 39, a one-way bearing 40 and a first bevel gear 41. The active bevel gear 38 is rotatably connected to the outer wall of the bottom cylinder 30 through a bevel gear frame (refer to Figure 6 ), the driven bevel gear 39 is meshed with the active bevel gear 38 and is rotatably connected to the bevel gear frame, the one-way bearing 40 is arranged on the side of the active bevel gear 38 close to the limit gear 37, the outer ring of the one-way bearing 40 is coaxially fixedly connected to the limit gear 37, and the inner ring is coaxially fixedly connected to the active bevel gear 38, the first bevel gear 41 is rotatably arranged inside the bottom cylinder 30 and is coaxially fixedly connected to the driven bevel gear 39, and the first bevel gear 41 is the output end of the two-way crushing mechanism 36. When the limit gear 37 rotates, according to the above, when the bottom cylinder 30 rotates forward, the reference Figure 7 At this time, the bottom cylinder 30 rotates clockwise, and the limiting gear 37 rotates counterclockwise. At this time, the inner ring and the outer ring of the one-way bearing 40 can rotate synchronously, that is, the limiting gear 37 will drive the active bevel gear 38 to rotate through the one-way bearing 40, and after the active bevel gear 38 rotates, it will drive the first bevel gear 41 to rotate through the driven bevel gear 39.

[0027] Similarly, when the bottom cylinder 30 is reversed, even if the inner ring and the outer ring of the one-way bearing 40 rotate relatively, the limiting gear 37 cannot drive the active bevel gear 38 to rotate through the one-way bearing 40 .

[0028] In order to realize the movement of the lower slide plate 31, the following features are also specifically provided: The crushing mechanism 16 further includes a plurality of second bevel teeth 42, a plurality of sliding gears 43 and a plurality of sliding racks 44. The plurality of second bevel teeth 42 are respectively arranged in an array along the inner wall of the bottom cylinder 30 in an equiangular rotation manner. The plurality of second bevel teeth 42 are respectively connected to the output end of the bidirectional crushing mechanism 36 in a transmission manner (as mentioned above, since the output end of the bidirectional crushing mechanism 36 is the first bevel teeth 41, the plurality of second bevel teeth 42 are respectively meshed with the plurality of first bevel teeth 41. The meshing diagram of the first bevel teeth 41 and the second bevel teeth 42 is shown in FIG. Figure 7 ), a plurality of second bevel teeth 42 are respectively coaxially fixedly connected to a plurality of sliding gears 43, a plurality of sliding racks 44 are respectively meshed with a plurality of sliding gears 43 and the upper ends are fixedly connected to the lower slide plate 31. When the bottom cylinder 30 rotates clockwise, under the action of the one-way bearing 40, the first bevel teeth 41 will drive the corresponding sliding gear 43 to rotate through the second bevel teeth 42, the rotation of the sliding gear 43 will drive the corresponding sliding rack 44 to move upward, and the movement of the sliding rack 44 will drive the lower lower slide plate 31 fixed thereto to move upward (refer to Fig. 9), ensure that during the clockwise rotation of the bottom cylinder 30, a plurality of steel needles 28 can extend upward through the lower plate 29 to facilitate the tearing of the rhizome Chinese medicine.

[0029] In order to prevent the sliding rack 44 from continuously moving upwards due to the continuous rotation of the sliding gear 43 when the bottom cylinder 30 rotates, the following features are specifically provided: The crushing mechanism 16 further includes a plurality of buffer tooth blocks 45, a plurality of buffer springs 46 and a plurality of buffer pins 47. The plurality of buffer tooth blocks 45 are respectively arranged below the plurality of sliding racks 44 (see Figure 7 ), each buffer tooth block 45 is provided with two buffer springs 46 at one end close to the sliding rack 44, the upper end of the buffer spring 46 is fixedly connected to the sliding rack 44, and the lower end is fixedly connected to the buffer tooth block 45, a plurality of buffer pins 47 are respectively arranged coaxially with the plurality of buffer springs 46, the upper end of the buffer pin 47 is fixedly connected to the sliding rack 44, and the lower end is slidably connected to the buffer tooth block 45, and a plurality of sliding gears 43 are respectively meshed with the plurality of buffer tooth blocks 45. When the sliding rack 44 moves upward, because the bottom cylinder 30 rotates continuously at this time, in order to prevent the bottom cylinder 30 from rotating and causing the sliding rack 44 to move continuously, a plurality of sliding gears 43 will continuously mesh with a plurality of buffer tooth blocks 45, but at this time, under the action of the buffer spring 46, a plurality of buffer tooth blocks 45 will reciprocate in the vertical direction, so that the sliding gear 43 rotates continuously, but the sliding rack 44 cannot move upward to achieve dynamic balance. In this process, because the sliding rack 44 will drive the lower sliding plate 31 to move, the lower sliding plate 31 will drive the several steel needles 28 fixed to it to perform small reciprocating vibrations in the vertical direction during the movement. At this time, the relative movement between the several steel needles 28 that pierce the rhizome of Chinese medicine and the rhizome of Chinese medicine is more intense, and the impact force and shear force generated are also greater, which can better overcome the toughness and hardness of the fibrous tissue, break the rhizome of Chinese medicine into smaller particles, and improve the crushing effect.

[0031] In order to drive the bottom drum 30 to rotate, the following features are also specifically provided: The power mechanism 2 also includes a second motor 9, a driving gear 10, a driving gear ring 11, a driving disc 12, two limiting sleeves 13 and two limiting rods 14.

When the second motor 9 is started, the second motor 9 will drive the driving gear ring 11 to rotate through the driving gear 10, and the rotation of the driving gear ring 11 will drive the two limit rods 14 to revolve along the circumferential direction of the driving disc 12 through the driving disc 12, and the revolution of the limit rod 14 will drive the limit sleeve 13 to revolve, and the revolution of the limit sleeve 13 will drive the rotating disc 15 fixedly connected thereto to rotate, and the rotation of the rotating disc 15 will drive the bottom cylinder 30 fixed thereto to rotate. During this process, the relative sliding of the limiting sleeve 13 and the limiting rod 14 will adaptively adjust the movement of the bottom tube 30 .

[0032] The working principle of the device is that the operator places the root and stem Chinese medicine on the upper end of the lower plate 29 (reference Figure 2 It can be seen that when the lifting plate 8 drives the bottom cylinder 30 to move in the vertical direction, since the limit gear ring 35 has a certain depth at this time, the limit gear ring 35 and the plurality of limit gears 37 slide relative to each other while maintaining the meshing state, that is, when the bottom cylinder 30 is at the lowest point, a gap is generated between the upper end of the bottom cylinder 30 and the lower end of the top cylinder 21, and the operator can put the root and tuber Chinese medicine into the upper end of the lower plate 29 through the upper end of the bottom cylinder 30), and then the first motor 4 starts and drives the bottom cylinder 30 to move in the direction close to the top cylinder 21. In the subsequent processing process, the second motor 9 starts to drive the bottom cylinder 30 to rotate.

[0033] When the bottom cylinder 30 approaches the top cylinder 21 until the center column 22 and the guide column 23 abut against each other, as the center column 22 and the guide column 23 continue to abut against each other, the upper sliding plate 18 will drive the plurality of steel needles 28 to extend downward through the upper plate 17, and at this time, under the action of the second motor 9, the rotating plate 15 will drive the bottom cylinder 30 to rotate, and the rotation direction at this time is specified to be forward rotation (referring to the foregoing, it can be seen that when the bottom cylinder 30 rotates forward, the inner ring and the outer ring of the one-way bearing 40 can rotate synchronously, that is, the limit gear 37 will drive the active bevel gear 38 to rotate through the one-way bearing 40, and the active bevel gear 38 will rotate. 8 After the rotation, the first bevel gear 41 will be driven to rotate through the driven bevel gear 39. Similarly, when the bottom cylinder 30 is reversed, even if the inner ring and the outer ring of the one-way bearing 40 will rotate relatively, that is, the limit gear 37 cannot drive the active bevel gear 38 to rotate through the one-way bearing 40), when the rhizome Chinese medicine is crushed, during this process, the lower sliding plate 31 drives a number of steel needles 28 to extend upward through the lower plate 29, and the upper sliding plate 18 drives a number of steel needles 28 to extend downward through the upper plate 17, and the rhizome Chinese medicine located at the upper end of the lower plate 29 will be pierced by the staggered steel needles 28. The steel needles 28 passing through the lower plate 29 and the upper plate 17 will crush the rhizome Chinese medicine during the rotation process, and this crushing process is more suitable for the tearing of rhizome Chinese medicine, which is conducive to reducing the damage to the effective ingredients in the rhizome Chinese medicine.

[0034] When the rotating disk 15 drives the bottom cylinder 30 to reverse, the lower sliding disk 31 will drive the steel needles 28 to move downward. At this time, the rhizome Chinese medicine located at the upper end of the lower disk 29 is only pierced by the steel needles 28 of the upper disk 17. Then, due to the continuous rotation of the lower disk 29, the rhizome Chinese medicine at the upper end of the lower disk 29 will be redistributed during the rotation process, which is convenient for the subsequent continuous piercing by the steel needles 28 extending out of the lower disk 29, thereby improving the crushing efficiency.

[0035] After the crushing is completed, because there are gaps between the steel needles 28, the crushed rhizome Chinese medicine will become strips. Compared with the whole rhizome Chinese medicine before crushing, the strip-shaped material (i.e., the strip-shaped rhizome Chinese medicine) has a reduced weight and enhanced flexibility. At this time, if the strip-shaped material is entangled with multiple steel needles 28 (if the rhizome Chinese medicine to be processed is relatively dry, after being shredded, there will be adsorption between the dry strip-shaped material and the steel needles 28 due to static electricity), then if the steel needles 28 do not retract, this part of the material will be entangled with the steel needles 28, and because the weight of the strip material itself is too light, the friction between this part of the strip material and the steel needles 28 is greater than its own gravity, so it cannot fall by itself under the action of gravity, and the operator needs to handle it manually at this time. At the same time, if the steel needles 28 located at the top are always in an extended state, this part of the steel needles 28 will increase the risk of accidental injury to the operator when the operator is loading and taking materials (when taking materials, the operator needs to use a clamp to clamp the crushed rhizome Chinese medicine from the upper end of the lower plate 29).

[0036] Therefore, when the bottom tube 30 is separated from the top tube 21, the upper sliding plate 18 will drive the plurality of steel needles 28 to move upward and pass through the upper plate 17 for retraction.

[0037] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
