The power components 2 include a motor 26, a gear 27, and a gear ring 28. The motor 26 is located on the side of the primary crushing box 1. The gear 27 is connected to the output shaft of the motor 26. The gear ring 28 is installed on the outer periphery of the hollow rotating tube 51 on the corresponding side and meshes with the gear 27. A protective shell 25 is provided on the side of the primary crushing box 1 adjacent to the power components 2. The motor 26 is installed on the outside of the protective shell 25. The gear 27 and the gear ring 28 are both located inside the protective shell 25.

[0018] The crushing chamber 3 is connected to the bottom of the preliminary crushing box 1. The upper part of the inner cavity of the crushing chamber 3 is a cylindrical cavity, and the lower part of its inner cavity is a conical structure. The bottom of the crushing chamber 3 has an opening. A discharge trough 4 is provided below the crushing chamber 3 and is fixedly connected to the crushing chamber 3. The upper and lower parts of the grinding head 11 are both conical structures. Several grinding teeth 33 are provided on the surface of the grinding head 11 and the lower part of the inner wall of the crushing chamber 3. The bottom of the grinding head 11 is connected to an inner rotating tube 131. The bottom of the discharge trough 4 is equipped with a power component 1 for driving the inner rotating tube 131 to rotate. The power component 1 includes a motor 14, a gear 15, and a gear ring 16. The motor 14 is installed at the bottom of the discharge trough 4. The gear 15 is connected to the output shaft of the motor 14. The gear ring 16 is installed on the outer periphery of the inner rotating tube 131 and meshes with the gear 15. The inner upper end of the crushing chamber 3 is provided with a funnel 7, the bottom end of the funnel 7 is connected to a conveying pipe 8, the outer periphery of the bottom end of the conveying pipe 8 is provided with an annular partition 10, the spiral blade 9 is provided on the inner side of the conveying pipe 8, the center of the spiral blade 9 is provided with an outer rotating pipe 12, the upper end of the outer rotating pipe 12 is connected to a circular cylinder 19, the upper end of the grinding head 11 is connected to an inner rotating pipe 132, the inner rotating pipe 132 movably passes through the outer rotating pipe 12, a limiting ring 17 is provided in the inner cavity of the circular cylinder 19, the limiting ring 17 is connected to the inner rotating pipe 132, a spring 18 is sleeved on the inner rotating pipe 132 located at the bottom end of the limiting ring 17, a plurality of keys 21 are connected on the limiting ring 17, a plurality of keyways 191 are opened on the upper end of the inner wall of the circular cylinder 19 for sliding of the plurality of keys 21, and an annular groove 192 is opened on the lower end of the inner cavity of the circular cylinder 19.

[0019] The pulverizing roller 5 has a hollow cooling channel II. Both ends of the cooling channel II are connected to the hollow rotating tubes 51 on both sides. The outer ends of the four hollow rotating tubes 51 are respectively equipped with a rotary joint II 29, a rotary joint III 30, a rotary joint IV 31, and a rotary joint V 32. Rotary joint II 29 and rotary joint III 30 are both connected to the output end of a water pump. Drain pipes are connected to rotary joint IV 31 and rotary joint V 32. The water pump delivers cold water through rotary joint II 29 and rotary joint III 30 to the cooling channel II of the two pulverizing rollers 5 to cool the pulverizing rollers 5. The cooled water is discharged to the outside through the drain pipes on rotary joint IV 31 and rotary joint V 32. This process forms a continuous water cooling cycle, which effectively controls the heat generated by friction during the pulverizing process and prevents the active ingredients of the medicinal materials from being destroyed by high temperature.

[0020] The working principle of this technical solution is as follows: During the initial crushing stage, motor 26 is started and driven by gear 27 and gear ring 28, causing the two crushing rollers 5 to rotate in opposite directions inside the initial crushing box 1, which can crush the Chinese herbal raw materials put into the initial crushing box 1 for the first time.

[0021] The material that has been initially crushed enters through the funnel 7 at the top of the crushing chamber 3. Inside the conveying pipe 8, the spiral blades 9 rotate stably under the drive of the outer rotating pipe 12. This conveying process not only realizes the transfer of materials, but more importantly, it pre-compresses the materials through the special structure of the spiral blades, thereby eliminating the loose state of the materials and increasing the density of the materials. The annular baffle 10 at the bottom of the conveying pipe ensures that the materials enter the grinding area evenly and controllably.

[0022] After the material enters the grinding area, the motor drives the gear 15 to rotate. The rotation of the grinding head 11 is achieved through the transmission of the gear 15 and the gear ring 16. The gap formed between the unique conical structure of the grinding head 11 and the inner wall of the grinding chamber 3 gradually decreases from top to bottom. In addition, the grinding teeth 33 are densely distributed on the surface, generating a strong grinding compound effect during the relative motion. This progressive grinding mechanism ensures that the material can be finely ground.

[0023] When the pressure in the grinding zone rises abnormally due to excessive material, the device automatically activates the protection mechanism. Under the abnormal pressure, the spiral blade 9 moves upward as a whole, causing the key 21 to slide from the keyway 191 into the annular groove 192. This structural change causes the outer rotating tube 12 to disengage from the transmission system. At this time, the spiral blade 9 stops rotating, thereby interrupting the material supply. After the pressure returns to normal, the key 21 re-enters the keyway 191 under the reset action of the spring 18, allowing the system to return to normal operation.

[0024] The material that has been pulverized into ultrafine particles is discharged through the bottom opening of the pulverizing chamber 3 and slides into the collection container along the inclined discharge chute 4.

[0025] Example 2 like Figure 3 As shown, the present invention proposes a traditional Chinese medicine ultrafine pulverizing device. Compared with Embodiment 1, in this embodiment, the grinding head 11 has a hollow cooling channel 1. The two ends of the cooling channel 1 are connected to the inner rotating tube 131 and the inner rotating tube 2 132 respectively. The bottom end of the inner rotating tube 131 is equipped with a rotary joint 6 34, and the upper end of the inner rotating tube 2 132 is equipped with a rotary joint 1 24. The inner side of the pulverizing chamber 3 is provided with a protective shell 1 23. The protective shell 1 23 penetrates the inner and outer sides of the pulverizing chamber 3. The outer end of the protective shell 1 23 is open. The rotary joint 1 24 is located inside the protective shell 1 23.

[0026] In this invention, the rotary joint 34 is connected to the output end of the water pump. The water output by the water pump flows into the interior of the inner rotating tube 131 through the rotary joint 34, and finally enters the cooling channel 1 inside the grinding head 11 to cool the grinding head 11, thereby reducing the grinding temperature and ensuring the activity of the medicine. The water in the grinding head 11 flows into the rotary joint 24 through the inner rotating tube 2 132, and finally is discharged through the pipe connected to the rotary joint 24. This circulation system is specifically designed for the large amount of frictional heat generated during fine grinding, and can quickly and effectively remove heat to ensure that the temperature of the grinding area is always kept within the safe range of the active ingredients of the medicinal material.

[0027] The protective housing 23 provides a reliable protective environment for the rotary joint 24. The protective housing extends through the inside and outside of the crushing chamber 3. The cross-section of the protective housing 23 is a triangular structure, which prevents materials from accumulating on the protective housing 23.

[0028] Example 3 like Figure 5 As shown, the present invention proposes a traditional Chinese medicine ultrafine pulverizing device. Compared with Embodiment 2, in this embodiment, the bottom end of the protective shell 23 is connected to the outer jacket 20, the upper part of the circular cylinder 19 is movably disposed inside the outer jacket 20, and a pressure sensor 22 is installed on the upper inner side of the outer jacket 20.

[0029] In this invention, when the cylindrical body 19 rises and the key 21 slides to the inside of the annular groove 192, the upper end of the cylindrical body 19 contacts the pressure sensor 22. The pressure sensor 22 feeds back the signal to the control panel 6, and the control panel 6 stops driving the crushing roller 5 or reduces the speed of the crushing roller 5.

[0030] Based on Embodiment 2, in this embodiment, when the pressure in the grinding area rises abnormally, the cylindrical body 19 moves upward under pressure. At the same time, the key 21 slides from the keyway 191 into the annular groove 192, and the upper end of the cylindrical body 19 comes into contact with the pressure sensor 22. The pressure sensor 22 immediately transmits the detected signal to the control panel 6. After receiving the pressure signal, the control panel 6 can first immediately stop the drive of the crushing roller 5, interrupting the material supply at the source; secondly, it can reduce the speed of the crushing roller 5, thereby reducing the feed amount; and it can also activate the audible and visual alarm device to prompt the operator to intervene.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
