Description

Technical Field

[0001] This invention belongs to the field of Chinese medicinal material crushing technology, specifically relating to an energy-saving Chinese medicinal material crushing device that can be manually driven. Background Technology

[0002] Traditional Chinese medicinal herbs are typically crushed using methods such as pounding or crushing, or by using rollers to squeeze and shear them. Both methods use mechanical force to break down the physical structure of the herbs. However, for roots and rhizomes that are fibrous and tough, such as loquat leaves, licorice, and mulberry bark, pounding is a better method. If these herbs are squeezed and sheared, excessive crushing will affect their medicinal properties.

[0003] In existing technologies, to improve the efficiency of crushing medicinal materials, automatic crushing devices are typically used, based on a crushing cylinder and a crushing rod (with a crushing head at the end). For example, patent application number CN201820143803.6, entitled "A High-Efficiency Crushing Device for Traditional Chinese Medicine," describes such a device. This device uses a rotating disc and connecting rod to drive a connecting seat to reciprocate, achieving continuous crushing of the medicinal materials. The speed and force of the crushing head are positively correlated, and the crushing head (or the hammering force on the medicinal materials) needs to be provided by the rotating disc. Therefore, the rotating disc must have a certain speed. Consequently, in this method, the rotating disc can only be electrically driven (manual rotation speed cannot meet the crushing force requirements), and both the crushing frequency and force are fixed. However, in teaching or student experiments, students need to operate manually and adjust the force and frequency of crushing the herbs themselves to intuitively perceive the relationship between the texture of different herbs and the crushing effect, deepen their understanding of the processing principle of herbs, and accurately control the degree of crushing. At this time, the electric drive method obviously cannot meet the teaching needs, and the electric drive method also has the drawback of energy waste. Summary of the Invention

[0004] This invention provides an energy-saving Chinese herbal medicine crushing device that can be manually driven, aiming to solve the problem of poor adaptability of existing electrically driven Chinese herbal medicine crushing devices due to their inability to meet the needs of teaching scenarios.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an energy-saving Chinese herbal medicine crushing device that can be manually driven, comprising:

[0006] The base has a horizontally set platform for placing the mortar and pestle;

[0007] A fixed box is connected to the base and located above the mounting platform;

[0008] A connecting slide column is slidably disposed at the bottom of the fixed box in a vertical direction. The bottom end of the connecting slide column extends out of the fixed box and is connected to the mortar and pestle. The top end of the connecting slide column is located in the fixed box and is provided with a limiting structure.

[0009] A drive assembly, disposed on the fixed box, includes a drive slide rod located inside the fixed box and capable of reciprocating along the vertical direction; the bottom end of the drive slide rod is adapted to the limiting structure; the drive assembly is used to drive the connecting slide column upward through the drive slide rod during hand cranking.

[0010] A power storage and release component is provided corresponding to the limiting structure. The power storage and release component is used to store power when the connecting slide column slides upward, and after the connecting slide column moves to a preset height, it releases the connection between the limiting structure and the driving slide rod, and pushes the connecting slide column downward to impact.

[0011] In one possible implementation, the base includes:

[0012] The base has the aforementioned mounting platform at its top;

[0013] The connecting arm is fixedly connected to the base at its bottom end and to the fixed box at its top end.

[0014] In one possible implementation, the fixing box includes:

[0015] The housing is fixedly connected to the base;

[0016] A guide cylinder is fixed to the bottom end of the housing and has a connecting cavity with its axis arranged vertically and for sliding connection with the connecting slide column; the top end of the guide cylinder forms an upper annular folded edge;

[0017] The top of the connecting slide column is provided with an annular limiting disc located in the housing and capable of contacting the upper annular folded edge.

[0018] In one possible implementation, the limiting structure includes:

[0019] A fastening ring is coaxially arranged with the annular limiting plate and fixedly connected to the annular limiting plate; the fastening ring is provided with two symmetrical and through sliding cavities, both of which are arranged along the radial direction of the fastening ring;

[0020] Two limiting sliders are provided, and the two limiting sliders are slidably disposed in the two sliding cavities respectively; the inner end of each limiting slider extends into the central hole of the fastening ring and has a first inclined surface; the outer end extends out of the limiting slider; each limiting slider is provided with a limiting post, and the limiting post is adapted to the limiting slide opening provided on the fastening ring to constrain the stroke of the limiting slider;

[0021] Two elastic elements are provided, each corresponding to one of the two limiting sliders; each elastic element is used to continuously bounce the corresponding limiting slider to maintain a tendency to move into the central hole.

[0022] In one possible implementation, the bottom end of the drive slide is provided with a circular limiting cap, and the bottom end of the circular limiting cap is provided with an annular second inclined surface. The second inclined surface is adapted to two first inclined surfaces. The second inclined surface is used to squeeze the two first inclined surfaces after the drive slide moves downward, so that the circular limiting cap moves below the two limiting sliders.

[0023] The annular limiting plate is provided with a clearance groove for the circular limiting cap to extend into.

[0024] In one possible implementation, the energy storage and release component includes:

[0025] A spring is disposed in the guide cylinder and sleeved on the connecting slide column. The top end of the spring abuts against the upper annular folded edge, and the bottom end abuts against the limiting ring disposed on the outer wall of the connecting slide column. The spring is used to continuously push the connecting slide column so that the connecting slide column has a drive to keep moving downward.

[0026] Two release components are provided, which are disposed in the housing and located above the limiting sliders; each release component has two vertically downward extending functional rods, each functional rod corresponding to one of the two limiting sliders; each release component has a third inclined surface at its bottom end;

[0027] Each of the limiting sliders has an opening at its outer end that corresponds to the corresponding functional rod, and a fourth inclined surface that is adapted to the third inclined surface is provided at the end of the opening away from the fastening ring.

[0028] When the limiting slider moves upward, the corresponding functional rod, through the cooperation of the fourth inclined surface and the third inclined surface, drives the limiting slider to move outward of the fastening ring, thereby releasing the connection between the driving slide rod and each limiting slider.

[0029] In one possible implementation, the release element is detachably connected to the housing;

[0030] The housing is provided with multiple sets of connection positions for fixing the release component, and each connection position is spaced apart along the vertical direction.

[0031] In one possible implementation, the driving component further includes:

[0032] The crankshaft is horizontally rotatably mounted on the fixed housing and has an eccentric adapter shaft;

[0033] The connecting rod has one end rotatably connected to the adapter shaft and the other end rotatably connected to the top of the drive slide rod;

[0034] A hand-cranked turntable is located outside the fixed box and is coaxially connected to one end of the crankshaft;

[0035] The fixed box is provided with a fixed cylinder for the drive slide rod to slide through.

[0036] In one possible implementation, the mortar and pestle has a mortar groove with an open top;

[0037] The mortar and pestle are detachably connected to the mounting platform.

[0038] In one possible implementation, the mortar and pestle are detachably connected to the connecting slide.

[0039] This invention provides a manually driven, energy-saving herbal medicine crushing device. Compared to existing technologies, the drive assembly uses a hand-cranked mechanism to provide driving force, and the drive slide rod within the drive assembly can reciprocate vertically under its influence. The bottom end of the drive slide rod can connect with a limiting structure at the top of the connecting slide column, ensuring that the connecting slide column moves upward synchronously during the upward movement of the drive slide rod. During the upward movement of the drive slide rod, the energy storage and release component simultaneously stores energy in the drive slide rod through energy conversion. When the connecting slide column reaches a preset height, the connection between the limiting structure and the drive slide rod is released by the energy storage and release component. Subsequently, the energy storage and release component drives the combination of the drive slide rod and the mortar and pestle downward, pounding the herbs inside the mortar and pestle.

[0040] In this implementation, the drive component provides an upward force to the connecting slide column only through the drive slider, without participating in the downward force of the connecting slide column. The downward force of the connecting slide column comes entirely from the energy storage and release component. Moreover, the frequency of crushing can be adjusted by the speed of hand cranking. This method is more suitable for teaching or student experiments. The operator can adjust the hand cranking frequency at any time according to the actual crushing situation, thereby changing the crushing frequency. For example, when crushing loquat leaves, a slower hand cranking speed and a smaller amplitude can be used first to observe whether the leaves are initially crushed. If it is found that the fiber structure of the leaves has not been broken, the hand cranking speed can be increased, the shaking amplitude can be increased, and the crushing frequency can be increased until the ideal crushing state is achieved. This process, which can be started, stopped, observed, and adjusted at any time, allows students to intuitively feel the relationship between frequency, force, and crushing effect, fully understand the processing principle of crushing Chinese medicinal materials, and meet the practical needs of teaching or experimental scenarios. Compared with the fixed parameters of electric drive devices, it can better achieve teaching objectives. Attached Figure Description

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0062] The directions or similar terms used throughout this invention, such as "front," "back," "left," "right," "top," "bottom," "inner," "outer," and "side," are mainly for reference to the directions in the accompanying drawings. These directions or similar terms are only used to assist in explaining and understanding the embodiments of this invention and are not intended to limit this invention.

[0063] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The present invention will now describe an energy-saving, manually operated herbal medicine crushing device. The manually operated, energy-saving herbal medicine crushing device includes a base 10, a fixed box 20, a connecting slide column 30, a drive assembly 50, and a power storage and release assembly 60. The base 10 has a horizontally arranged platform 11 for placing a crushing cylinder 80. The fixed box 20 is connected to the base 10 and is located above the platform 11. The connecting slide column 30 is slidably disposed at the bottom of the fixed box 20 in a vertical direction, with its bottom end extending out of the fixed box 20 and connecting to a crushing rod 90. The top end of the connecting slide column 30 is located within the fixed box 20 and is provided with a limiting structure 40. The drive assembly 50 is disposed on the fixed box 20 and includes a drive slide rod 51 located inside the fixed box 20 and capable of reciprocating in a vertical direction. The bottom end of the drive slide rod 51 is adapted to the limiting structure 40. The drive assembly 50 can move the connecting slide column 30 upwards via the drive slide rod 51 during hand cranking.

[0064] The power release component 60 is configured to correspond with the limiting structure 40. The power release component 60 can store power by sliding the connecting slide column 30 upward. After the connecting slide column 30 moves to a preset height, it releases the connection between the limiting structure 40 and the drive slide rod 51 and pushes the connecting slide column 30 downward to impact.

[0065] The base 10 serves as a connecting carrier, ensuring the fixed installation of other components. Simultaneously, the base 10 provides a stable placement for the mortar 80, preventing it from shifting or tipping over during the mortaring process and providing fundamental support for crushing. The fixed box 20 provides a stable assembly space for the connecting slide column 30, drive assembly 50, and power release assembly 60, ensuring a scientifically arranged space.

[0066] The working principle is as follows: a mortar and pestle 80 containing the target medicinal materials (such as loquat leaves, licorice, and mulberry bark) is placed on a horizontal platform 11 of the base 10. Then, a hand-cranked drive assembly 50 drives a drive slide rod 51 to move vertically upwards. Since the bottom of the drive slide rod 51 is fitted with a limiting structure 40 at the top of the connecting slide column 30, the drive slide rod 51 pulls the connecting slide column 30 upwards synchronously through the limiting structure 40 as it moves upwards. During the upward movement of the connecting slide column 30, a power-saving release assembly 60 simultaneously stores power. When the connecting slide column 30 reaches a preset height, the power-saving release assembly 60 triggers the separation of the limiting structure 40 and the drive slide rod 51, disengaging their connection. At this moment, the elastic potential energy stored in the power-saving release assembly 60 is released instantaneously, pushing the connecting slide column 30 downwards rapidly. The mortar rod 90 at the bottom of the connecting slide column 30 drives the mortar head downwards to impact the medicinal materials inside the mortar and pestle 80, completing one pounding and crushing action. By repeating the above process of hand-cranking, charging, and releasing, the medicinal materials can be continuously pounded.

[0067] The energy-saving, manually driven herbal medicine crushing device provided in this embodiment, compared with the prior art, uses a hand-cranked drive assembly 50 to provide driving force, and the drive slide rod 51 in the drive assembly 50 can move vertically back and forth under the drive of the drive assembly 50. The bottom end of the drive slide rod 51 can be connected to the limiting structure 40 at the top of the connecting slide column 30, thereby ensuring that the connecting slide column 30 is driven upward synchronously during the upward movement of the drive slide rod 51. During the upward movement of the drive slide rod 51, the energy storage and release assembly 60 also stores energy in the drive slide rod 51 through energy conversion. When the connecting slide column 30 reaches the preset height, the connection between the limiting structure 40 and the drive slide rod 51 is released by the energy storage and release assembly 60. Subsequently, the energy storage and release assembly 60 drives the combination of the drive slide rod 51 and the pounding rod 90 downward, and pounds the herbs in the pounding cylinder 80.

[0068] In this method, the drive component 50 provides an upward force to the connecting slide column 30 only through the drive slide rod 51, and does not participate in the downward force of the connecting slide column 30. The downward force of the connecting slide column 30 comes entirely from the energy storage and release component 60. Moreover, the frequency of crushing can be adjusted by the speed of hand cranking. This method is more suitable for teaching or operator experiments. The operator can adjust the hand cranking frequency at any time according to the actual crushing situation, thereby changing the crushing frequency. For example, when crushing loquat leaves, a slower hand cranking speed and a smaller amplitude can be used first to observe whether the leaves are initially crushed. If it is found that the fiber structure of the leaves has not been broken, the hand cranking speed can be increased, the shaking amplitude can be increased, and the crushing frequency can be increased until the ideal crushing state is achieved. This process, which can be started and stopped at any time and can be adjusted independently, allows the operator to intuitively feel the relationship between frequency, force and crushing effect, fully understand the processing principle of crushing Chinese medicinal materials, meet the practical needs of teaching or experimental scenarios, and better achieve teaching objectives compared to the fixed parameters of electric drive devices.

[0069] The force of pounding the medicine can be controlled by setting a preset height, which corresponds to the upward stroke of the connecting slide 30. Furthermore, the drive assembly 50 is hand-cranked, requiring no electrical input. It converts human power into driving and pounding force, avoiding energy waste and noise generation.

[0070] In some embodiments, the base 10 may adopt the following... Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The base 10 includes a base 12 and a connecting arm 13. The top of the base 12 is provided with a mounting platform 11. The bottom end of the connecting arm 13 is fixedly connected to the base 12, and the top end is fixedly connected to the fixing box 20.

[0071] The base 12 provides a horizontal support surface for the mortar and pestle 80 via the mounting platform 11, ensuring the stability of the cylinder during mortar and pestle crushing. The connecting arm 13 acts as a bridge, firmly connecting the base 12 to the fixing box 20, ensuring the fixing box 20 is directly above the mounting platform 11. This guarantees that the vertical impact direction of the mortar and pestle rod 90 driven by the connecting slide 30 is aligned with the center of the mortar and pestle 80. This structure allows the height of the drive assembly 50 to be more easily adapted to the operator's posture in teaching scenarios. Operators can more conveniently observe the crushing process and flexibly adjust the frequency, achieving convenient changes in mortar and pestle crushing force and frequency. This enhances the practical experience and allows operators to perceive the relationship between the material texture and the crushing effect.

[0072] In some embodiments, the aforementioned fixing box 20 may be adopted as follows: Figure 2 , Figure 4 , Figure 5 and Figure 6 The structure shown. See also Figure 2 , Figure 4 , Figure 5 and Figure 6 The fixed box 20 includes a box body 21 and a guide cylinder 22. The box body 21 is fixedly connected to the base 10. The guide cylinder 22 is fixedly mounted on the bottom end of the box body 21 and has a connecting cavity with its axis arranged vertically and for sliding connection with the connecting slide column 30. The top end of the guide cylinder 22 forms an upper annular folded edge 23.

[0073] The top of the connecting slide column 30 is provided with an annular limiting plate 31 located in the housing 21 and capable of contacting the upper annular folded edge 23.

[0074] The guide cylinder 22 has a connecting cavity with its axis running vertically. The connecting slide column 30 is slidably connected in the connecting cavity, forming a vertical guide channel, so that the connecting slide column 30 can only move back and forth in the vertical direction, avoiding lateral swaying. At the same time, the upper annular fold 23 formed at the top of the guide cylinder 22 forms a limiting engagement with the annular limiting plate 31 at the top of the connecting slide column 30. When the connecting slide column 30 descends to its limit position, the annular limiting plate 31 contacts and abuts against the upper annular fold 23, preventing the connecting slide column 30 from continuing to descend and preventing it from detaching from the housing 21.

[0075] In this embodiment, regarding the formation of the upper annular folded edge 23, the guide cylinder 22 and the box body 21 can be connected by bolts, and the upper annular folded edge 23 can be an inner flange set at the top of the guide cylinder 22; of course, it can also be formed by a through hole set at the bottom of the box body 21 with a diameter smaller than the inner diameter of the guide cylinder 22.

[0076] In some embodiments, the limiting structure 40 may adopt the following: Figure 4 , Figure 6 and Figure 10 The structure shown. See also Figure 4 , Figure 6 and Figure 10 The limiting structure 40 includes a fastening ring 41, limiting sliders 43, and elastic elements 48. The fastening ring 41 is coaxially arranged with and fixedly connected to the annular limiting disk 31. The fastening ring 41 has two symmetrical and through sliding cavities 42, both of which are arranged radially along the fastening ring 41. There are two limiting sliders 43, which are slidably disposed in the two sliding cavities 42 respectively. The inner end of each limiting slider 43 extends into the central hole of the fastening ring 41 and has a first inclined surface 44. The outer end extends out of the limiting slider 43. Each limiting slider 43 has a limiting post 45, which is adapted to the limiting slide opening provided on the fastening ring 41 to constrain the stroke of the limiting slider 43. There are two elastic elements 48, each corresponding to one of the two limiting sliders 43. Each elastic element 48 can continuously bounce the corresponding limiting slider 43, maintaining a tendency to move into the central hole.

[0077] A fastening ring 41, coaxially fixed with the annular limiting disc 31, has two radially penetrating sliding cavities 42. Two limiting sliders 43 are slidably disposed in the sliding cavities 42, with their inner ends extending into the central hole and having a first inclined surface 44; their outer ends extend outward; and the limiting sliders 43 have limiting posts 45 that are adapted to the limiting sliding openings of the fastening ring 41 to constrain their travel. Two elastic elements 48 correspond to the limiting sliders 43 respectively, continuously bouncing as they move into the central hole.

[0078] When the drive slide bar 51 moves downward, its bottom structure interacts with the first inclined surface 44 of the limiting slider 43, pressing the limiting slider 43 to move outward, allowing the drive slide bar 51 to enter below the two limiting sliders 43. The elastic element 48 continuously pushes the limiting slider 43 to reset. When the drive slide bar 51 moves upward, the limiting slider 43 locks the drive slide bar 51, thereby driving the connecting slide post 30 to move upward synchronously. The cooperation between the limiting post 45 and the limiting slide opening limits the travel of the limiting slider 43, preventing excessive movement that could lead to structural failure.

[0079] The elastic element 48 continuously pushes the limiting slider 43 towards the center hole, making the connection between the drive slider 51 and the limiting structure 40 more stable. When the operator manually cranks the drive, the driving force can be efficiently transmitted to the connecting slide column 30, avoiding force loss due to slippage, ensuring that the connecting slide column 30 can stably move upward to store force, thereby guaranteeing the subsequent hammering force. The stroke constraint of the limiting post 45 and the limiting slide prevents the limiting slider 43 from moving excessively.

[0080] Regarding the elastic element 48, it can be a leaf spring, located on or within the fastening ring 41, with both ends resting on the fastening ring 41 and the middle position passing through the limiting slider 43. The leaf spring can be in a single-bow shape, bending outwards from the fastening ring. This technique is a conventional setup for those skilled in the art; of course, other existing methods can also be used, which will not be elaborated here.

[0081] In some embodiments, the connecting slide 30 and the driving slide 51 can be adopted as follows: Figure 6 and Figure 10 The structure shown. See also Figure 6 and Figure 10 The bottom end of the drive slide 51 is provided with a circular limit cap 52, and the bottom end of the circular limit cap 52 is provided with an annular second inclined part 53. The second inclined part 53 is adapted to the two first inclined surfaces 44. After the drive slide 51 moves down, the second inclined part 53 can squeeze the two first inclined surfaces 44, so that the circular limit cap 52 moves to the bottom of the two limit sliders 43.

[0082] The annular limiting plate 31 is provided with a clearance groove 32 into which the circular limiting cap 52 extends.

[0083] The diameter of the circular limiting cap 52 is larger than the support of the drive slide rod 51, forming an annular locking platform at the top of the circular limiting cap 52. When the drive slide rod 51 moves downward, the second inclined surface 53 of the circular limiting cap 52 contacts the first inclined surface 44 of the limiting slider 43. As the drive slide rod 51 continues to move downward, the second inclined surface 53 presses against the first inclined surface 44, generating a radial force that pushes the two limiting sliders 43 to slide outward, clearing the central channel, so that the circular limiting cap 52 can smoothly extend into the clearance groove 32 of the annular limiting disk 31 and reach below the limiting slider 43.

[0084] When the drive slide bar 51 moves upward, the limiting slider 43 resets under the action of the elastic element 48, and its inner end engages with the annular locking platform at the top of the circular limiting cap 52, thereby driving the slide bar 51 to move the connecting slide column 30 upward synchronously. After reaching the preset height, under the action of the power release component 60, the limiting slider 43 moves outward again, and the circular limiting cap 52 separates from the limiting slider 43, completing the power release. The precise fit between the second inclined surface 53 and the first inclined surface 44 allows the downward movement of the drive slide bar 51 to drive the sliding of the limiting slider 43, and it smoothly passes through the two limiting sliders 43 before entering the clearance groove 32.

[0085] In some embodiments, the aforementioned energy storage and release component 60 may employ, as follows: Figure 4 and Figure 6 The structure shown. See also Figure 4 and Figure 6 The power-release assembly 60 includes a spring 61 and release members 62. The spring 61 is disposed in the guide cylinder 22 and sleeved on the connecting slide column 30. The top end of the spring 61 abuts against the upper annular flange 23, and the bottom end abuts against the limiting ring 33 disposed on the outer wall of the connecting slide column 30, continuously pushing the connecting slide column 30 to maintain its downward movement. Two release members 62 are provided, disposed in the housing 21, and located above the limiting slider 43. Each release member 62 has two vertically extending downward functional rods 63, each corresponding to one of the two limiting sliders 43. The bottom end of each release member 62 has a third inclined surface 64.

[0086] Each limiting slider 43 has an opening 46 at its outer end that corresponds to the corresponding functional rod 63, and a fourth inclined surface 47 that is adapted to the third inclined surface 64 is provided at the end of the opening 46 away from the fastening ring 41.

[0087] After the limit slider 43 moves upward, the corresponding functional rod 63, through the cooperation of the fourth inclined part 47 and the third inclined part 64, drives the limit slider 43 to move to the outside of the fastening ring 41, so as to release the connection between the drive slide rod 51 and each limit slider 43.

[0088] When the connecting slide column 30 moves upward, the limiting ring 33 and the upper annular folded edge 23 jointly compress the spring 61, and the spring 61 stores elastic potential energy to achieve force storage. At the same time, the connecting slide column 30 drives the limiting slider 43 to move upward synchronously. When it moves to the preset height, the fourth inclined part 47 of the outer end through-hole 46 of the limiting slider 43 contacts the third inclined part 64 of the corresponding functional rod 63. As it continues to move upward, the third inclined part 64 squeezes the fourth inclined part 47, pushing the limiting slider 43 to move outward, releasing the engagement between the inner end of the limiting slider 43 and the circular limiting cap 52 of the driving slide rod 51. At this time, the elastic potential energy of the spring 61 is released, pushing the connecting slide column 30 to move downward quickly, driving the mortar 90 to impact the medicinal material. After release, the spring 61 pushes the connecting slide column 30 to move downward and reset, and the limiting slider 43 resets under the action of the elastic element 48, waiting for the next connection with the driving slide rod 51.

[0089] The spring 61's energy storage function converts the mechanical energy of manual operation into elastic potential energy, which is instantly converted into a powerful hammering force upon release. This compensates for the insufficient rotation speed of manual operation, ensuring effective crushing of coarse and tough medicinal materials without the need for electricity. The release component 62 achieves automatic release through its inclined surface structure, enabling continuous hammering, making operation convenient and efficient.

[0090] In this embodiment, the impact force is achieved by spring 61. The greater the compression of spring 61, that is, the higher the connecting slide 30 rises, the greater the kinetic energy it can generate after release.

[0091] In some embodiments, the release element 62 may be as follows: Figure 1 and Figure 7 The structure shown. See also Figure 1 and Figure 7 The release element 62 is detachably connected to the housing 21. The housing 21 is provided with multiple sets of connection positions 14 for fixing the release element 62, and each connection position 14 is spaced apart along the vertical direction.

[0092] The striking force of the mortar and pestle head driven by the mortar and pestle rod 90 is achieved by the spring 61. The greater the compression of the spring 61, the higher the connecting slide 30 rises, and the greater the kinetic energy generated after its release. Therefore, the height of the release component 62 can be adjusted to correspond to the rising height of the connecting slide 30.

[0093] As one implementation method of this embodiment, see [link to relevant documentation]. Figure 7 The release element 62 may include a fixed plate and a functional rod 63, with the functional rod 63 fixedly connected to the fixed plate. The fixed plate may be detachably connected to the side wall of the housing 21 by bolts. When a bolted connection structure is used, the connection position 14 may be vertically arranged connection holes.

[0094] In another embodiment of this invention, the release component 62 may include a fixed plate, a functional rod 63, and adjusting screws. The functional rod 63 is fixedly connected to the fixed plate. Both ends of the fixed plate extend horizontally out of the housing 21. Two adjusting screws are provided, each corresponding to one end of the fixed plate, and the adjusting screws are vertically positioned and rotatably connected to the housing 21. The adjusting screws are threadedly connected to the corresponding ends of the fixed plates, and the height of the fixed plates can be adjusted by rotating the adjusting screws. A vertical elongated opening is also required on the housing 21.

[0095] In some embodiments, the driving component 50 described above may employ, for example... Figure 2 The structure shown. See also Figure 2 The drive assembly 50 also includes a crankshaft 54, a connecting rod 55, and a hand crank 56. The crankshaft 54 ​​is horizontally rotatably mounted on the fixed housing 20 and has an eccentric adapter shaft. One end of the connecting rod 55 is rotatably connected to the adapter shaft, and the other end is rotatably connected to the top of the drive slide 51. The hand crank 56 is located outside the fixed housing 20 and is coaxially connected to one end of the crankshaft 54.

[0096] The fixed box 20 is provided with a fixed cylinder 57 for sliding connection of the drive slide rod 51.

[0097] Rotating the hand crank turntable 56 causes the crankshaft 54 ​​to rotate synchronously. The eccentric adapter shaft of the crankshaft 54 ​​performs circular motion, which is converted into vertical reciprocating motion of the drive slide rod 51 via the connecting rod 55. When the adapter shaft rotates upward, it pulls the drive slide rod 51 upward via the connecting rod 55; when it rotates downward, it pushes the drive slide rod 51 downward via the connecting rod 55. The fixed cylinder 57 provides vertical guidance for the drive slide rod 51, ensuring its reciprocating motion is stable. A stable hammering frequency can be obtained by rotating the turntable at a uniform speed, or the frequency can be changed by rotating at a variable speed. By controlling the rotation speed, the frequency can be gradually adjusted; the faster the turntable rotates, the higher the reciprocating frequency of the drive slide rod 51.

[0098] In some embodiments, the above-mentioned mortar and pestle 80 can be adopted as follows: Figure 1 and Figure 8 The structure shown. See also Figure 1 and Figure 8 The mortar and pestle 80 has a mortar groove with an open top. The mortar and pestle 80 are detachably connected to the mounting platform 11.

[0099] The mortar and pestle 80 and the mounting platform 11 can be connected by bolts, which facilitates disassembly and assembly and ensures the stability of the connection.

[0100] Multiple sets of threaded holes are provided on the mounting platform 11, and the diameter of the reference circle corresponding to each set of threaded holes increases sequentially.

[0101] In some embodiments, the aforementioned mortar and pestle 90 may be adopted as follows: Figure 1 and Figure 6 The structure shown. See also Figure 1 and Figure 6 The mortar 90 and the connecting slide 30 are detachably connected to facilitate the replacement and disassembly of the mortar 90.

[0102] The bottom end of the mortar 90 and the connecting slide 30 can be connected by a threaded structure.

[0103] It should be noted that the mortar head is located at the bottom end of the mortar rod 90, which has a certain length. During use, the mortar head at the bottom of the mortar rod 90 is located in the mortar groove, while the top end of the mortar rod 90 or the bottom end of the connecting slide column 30 is located above the mortar cylinder 80. This structure facilitates the installation of a sealing cap with a through hole on the top of the mortar cylinder 80 during the mortaring process.

[0104] In some embodiments, see Figure 9 The base 12 is equipped with a rotating disk with its axis vertically aligned and connected to a drive structure inside the base 12, allowing it to rotate under the drive of the drive structure. The top surface of the rotating disk serves as a mounting platform 11. Correspondingly, when the diameter of the mortar 80 is large, or the opening of the mortar groove is large, the rotation function can be activated.

[0105] For the large-diameter mortar and pestle 80, the energy-saving Chinese herbal medicine mortar and pestle device that can be manually driven provided in this embodiment may also include a feeding assembly 70. The feeding assembly 70 may include a first rack 71, a second rack 72, a gear 73, a flipping rod 74, and an elastic feeding element 75. The first rack 71 is arranged vertically and slidably disposed at the bottom end of the housing 21; the second rack 72 is arranged vertically and slidably disposed at the bottom end of the housing 21; the gear 73 is located between the first rack 71 and the second rack 72 and meshes with the first rack 71 and the second rack 72, and the gear 73 is rotatably connected to the bottom end of the housing 21.

[0106] The bottom end of the first rack 71 is connected to the bottom end of the annular limiting disk 31. The flipping rod 74 is rotatably connected to the bottom end of the second rack 72, and a torsion spring is provided on the connecting shaft. The flipping rod 74 has a tendency to continuously tilt downwards and rotate to a vertical state. The other end of the flipping rod 74 is connected to an elastic feeding component 75, which has a certain deformation capability.

[0107] In this embodiment, the second rack 72 needs to be located above the mortar, and its vertical central axis is spaced apart from the axis to the mortar. During the upward movement of the drive column, the annular limiting disc 31 drives the first rack 71 upward. As the gear 73 transmits power to the second rack 72, the second rack 72 moves downward. After the second rack 72 moves downward, the elastic material-pushing component 75 at the bottom of the flipping rod 74 contacts the inner wall of the mortar. Guided by the curved surface of the inner wall, the flipping rod 74 tilts upward, and the elastic material-pushing component 75 also deforms to a certain extent, ensuring that the material on the outside of the mortar is pushed inward. Combined with the rotation of the mortar cylinder 80, this ensures that all medicinal materials are pushed inward. When the drive column moves downward, it drives the first rack 71 downward, and then the gear 73 drives the second rack 72 upward until the flipping rod 74 and the elastic material-pushing component 75 disengage from the inner wall of the mortar, at which point the flipping rod 74 and the elastic material-pushing rod return to their original positions. This method can accommodate larger diameter mortars (80mm), enhancing its applicability.

[0108] To facilitate the limiting sliding connection of the first rack 71 and the second rack 72, and to facilitate the rotational connection of the gear 73, an auxiliary box 76 can be integrally connected to the bottom of the housing 21.

[0109] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
