Description

Technical Field

[0001] The invention relates to the technical field of pulverizers, in particular to a Chinese herbal medicine pulverizer. Background Art

[0002] Chinese herbal medicine grinder is a mechanical equipment specially used for crushing Chinese herbal medicine. It uses a motor to drive the blade, hammer or toothed disc and other components to run at high speed, quickly crushing the Chinese herbal medicine raw materials into fine particles or powder to meet the process requirements of Chinese medicine preparation, extraction, formula deployment, etc. It has the characteristics of high crushing efficiency, controllable particle size, simple operation, strong adaptability, etc. It can process Chinese herbal medicines in various forms such as roots, stems, leaves, flowers, fruits, seeds, etc., and is an indispensable key equipment in the field of Chinese medicine processing.

[0003] Hammer mills are widely used in the field of traditional Chinese medicine processing due to their efficient and continuous crushing capabilities. A rotating shaft is connected in the crushing chamber, and multiple circular mounting plates are fixed on the shaft. Multiple mounting rods are evenly and equidistantly arranged on the plates, and the hammers are connected to the mounting rods. At present, there are two main connection methods between the hammers and the mounting rods: fixed connection and rotating connection. The fixed connection method is suitable for brittle and medium-hard medicinal materials, and can efficiently complete the crushing task, while the rotating connection method is more suitable for fibrous, tough or oil-containing medicinal materials, and can effectively reduce material entanglement and equipment blockage. However, under the existing technology, if the hammer connection method needs to be switched according to the different characteristics of Chinese herbal medicines, the crusher casing must be disassembled when the device is shut down, and the internal hammers and their mounting components must be replaced.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-7The present invention provides a technical solution: a Chinese herbal medicine grinder, comprising a grinder housing 1 and a drive shaft 11 installed in the grinder housing 1, a circular mounting plate 12 is installed on the drive shaft 11, a plurality of mounting rods 13 are provided on the circular mounting plate 12, and a plurality of hammer pieces 2 are provided on the mounting rods 13 for crushing materials.

[0034] A blocking member 3 is provided on the hammer 2. The blocking member 3 includes two arc blocks 31 symmetrically fixedly connected to the side wall of the hammer 2. One end of the arc block 31 is close to the mounting hole on the hammer 2 for connecting with the mounting rod 13, and the other end is away from the mounting hole. The two arc blocks 31 are V-shaped as a whole.

[0035] When the end of the U-shaped slider 4 is between the ends of the two arc blocks 31, the U-shaped slider 4 and the arc block 31 form a locking structure to maintain the locked state of the hammer 2. In the process of the U-shaped slider 4 moving and retracting along the mounting rod 13, based on the V-shaped structure, the lock between the hammer 2 and the mounting rod 13 will be released first, and then the swing range of the hammer 2 will be gradually increased, thereby facilitating and quickly switching the installation state of the hammer 2 and improving work efficiency. The design of the arc block 31 not only can adjust the swing range of the hammer 2, but also can guide it to insert between the two arc blocks 31 when the U-shaped slider 4 is pushed out, thereby facilitating the locking of the hammer 2.

[0036] Specifically, in the process of the U-shaped slider 4 gradually retracting into the mounting rod 13, the distance between its end and the inner wall of the arc block 31 gradually increases, thereby achieving the effect of gradually increasing the swing amplitude of the hammer 2, and the adjustable swing range of the hammer 2 can significantly improve the adaptability and efficiency of the Chinese medicine grinder: by dynamically adjusting the swing angle, the equipment can accurately match the characteristics of different medicinal materials, and increasing the swing range can enhance the kneading and shearing effects on fibrous medicinal materials such as Eucommia ulmoides and Ganoderma lucidum, reduce entanglement and increase the powder output rate; reducing the swing range can optimize the impact efficiency of brittle medicinal materials such as Astragalus membranaceus and Angelica sinensis, reduce energy consumption and reduce the loss of heat-sensitive components; in addition, flexible adjustment of the swing range can also dynamically balance the wear area of ​​the hammer 2, extend its service life, and reduce the risk of motor overload by matching the load, comprehensively achieving controllable crushing particle size, reduced energy consumption and improved equipment stability.

[0037] At the same time, in the process of gradually increasing the swing range of the hammer 2, as the rectangular frame 32 drives the triangular block 51 to move, the contact position of the triangular block 51 and the cylinder 49 changes, and then the extrusion of the extrusion plate 48 is gradually loosened, so that the elastic pad 47 gradually recovers its deformation, and the pressure of the elastic pad 47 on the friction block 45 is reduced accordingly, thereby gradually reducing the friction force exerted on the hammer 2 when it rotates relative to the mounting rod 13, that is, gradually reducing the rotational resistance of the hammer 2. This method of dynamically adjusting the rotational resistance can, on the one hand, avoid the hammer 2 from having a high swing frequency and frequent collision and friction due to premature loosening when the initial range of activity is relatively small, thereby affecting the crushing stability; on the other hand, timely reducing the resistance as the swing range increases can reduce the energy loss of the hammer 2 during rotation, improve the rotational flexibility of the hammer 2, and enable the hammer 2 to contact and collide with the material more efficiently, thereby optimizing the crushing effect and improving the overall working efficiency and crushing quality of the Chinese herbal medicine crusher.

[0038] The U-shaped slider 4 is slidably disposed on the mounting rod 13 . The U-shaped slider 4 is adapted to the blocking member 3 and is used to achieve locking between the hammer 2 and the mounting rod 13 by cooperating with the blocking member 3 .

[0039] The pushing member 5 is disposed in the housing and connected to the U-shaped slider 4 , and is used to drive the U-shaped slider 4 to move and disengage from the blocking member 3 to cancel the locking between the hammer 2 and the mounting rod 13 .

[0040] The pusher 5 includes a rectangular frame 32 arranged on one side of the U-shaped slider 4. A sliding groove 33 is opened in the mounting rod 13. The rectangular frame 32 is located in the sliding groove 33 and is slidably connected to its inner wall. One end of the U-shaped slider 4 is rotatably connected to a shaft 1 34. The rectangular frame 32 is also rotatably connected to a shaft 1 34. A connecting rod 35 is fixedly connected between the two shafts 1 34. By moving the rectangular frame 32, the connecting rod 35 is driven to deflect, thereby driving the U-shaped slider 4 to move.

[0041] A pull rod 36 is slidably connected inside the mounting rod 13. One end of the pull rod 36 slides through the mounting rod 13, and the other end of the pull rod 36 is fixedly connected to a rectangular frame 32. A connecting rod 37 is fixedly connected between the multiple rectangular frames 32 in the mounting rod 13. An electric push rod 38 is fixedly connected to the crusher housing 1. A connecting piece 39 is provided between the electric push rod 38 and the pull rod 36. When the electric push rod 38 is started, the connecting piece 39 is used to push the rectangular frame 32 to move.

[0042] The connecting member 39 includes a circular ring 41 fixedly connected to one end of the pull rod 36, and a ring body 42 is rotatably connected to one side of the circular ring 41. The circular body 42 is fixedly connected to the extended end of the electric push rod 38, and a guide rod 43 is fixedly connected to the circular body 42. One end of the guide rod 43 slides through the crusher housing 1 to guide and limit the movement of the circular body 42. By starting the electric push rod 38, the circular body 42 is driven to move, thereby driving the circular ring 41 and the pull rod 36 to move.

[0043] A sliding groove 44 is formed on the mounting rod 13 , and a friction block 45 is slidably connected in the sliding groove 44 . The friction block 45 contacts and abuts against the inner wall of the mounting hole of the hammer 2 to provide resistance when the hammer 2 rotates relative to the mounting rod 13 .

[0044] A transmission member 46 is provided between the rectangular frame 32 and the friction block 45. When the rectangular frame 32 drives the U-shaped slider 4 to retract, the transmission member 46 first causes the friction block 45 to gradually press the hammer 2 and then gradually loosen it. In this way, when the initial swing amplitude of the hammer 2 is in a small range, its swing resistance is at its maximum state. As the subsequent swing range of the hammer 2 gradually increases, its swing resistance also tends to gradually decrease. Dynamic adjustment effect.

[0045] The transmission member 46 includes an elastic pad 47 fixedly connected to one side of the friction block 45, an extrusion plate 48 is installed on one side of the elastic pad 47, a cylinder 49 is fixedly connected to one side of the extrusion plate 48, and a triangular block 51 is fixedly connected to the side wall of the rectangular frame 32. The inclined surfaces of the cylinder 49 and the triangular block 51 are in contact with each other. Specifically, in the initial state of the device, one end of the U-shaped slider 4 is embedded between the ends of the two arc blocks 31, forming a locking structure for the hammer 2 and the mounting rod 13. At this time, the elastic pad 47 is in a naturally relaxed state. When the rectangular frame 32 is moved to drive the U-shaped slider 4 to gradually separate from the end of the arc block 31, an inclined surface of the triangular block 51 on it begins to push the cylinder 49, thereby pushing the extrusion plate 48, applying pressure to the elastic pad 47, causing the elastic pad 47 to deform. The deformation of the elastic pad 47 increases the friction resistance of the friction block 45 to the hammer 2. When the U-shaped slider 4 is completely separated from the end of the arc block 31, the pressure of the friction block 45 on the hammer 2 reaches a maximum value. Thereafter, in the process of continuing to move the U-shaped slider 4 to gradually increase the swing range of the hammer 2, the rectangular frame 32 continues to move, driving the other inclined surface of the triangular block 51 to move, which gradually reduces the pushing force on the cylinder 49. The pressure on the elastic pad 47 is reduced accordingly, and the deformation is gradually restored, thereby gradually reducing the friction resistance of the friction block 45 to the hammer 2.

[0046] There are four mounting rods 13 evenly spaced on the circular mounting plate 12, two in a group, and two electric push rods 38 are also provided. The two electric push rods 38 are located at both ends of the crusher housing 1 and are connected to the pull rods 36 in the two groups of mounting rods 13. By starting different electric push rods 38, half of the hammer 2 in the device can be in a fixed state and the other half in a rotatable state. This design effectively improves the applicability of the device, so that it can better adapt to different crushing needs.

[0047] Example 2: Please refer to Figures 1-10 The present invention provides a technical solution: Example 2 is another specific implementation of the connecting member 39 in Example 1.

[0048] The connecting member 39 includes a cylindrical body 49 fixedly connected to one end of the pull rod 36, and an annular groove 53 is provided on the cylindrical body 49. A guide groove 54 is provided on the drive shaft 11. A shift plate 55 is slidably connected in the guide groove 54, and a C-shaped groove 56 is provided at one end of the shift plate 55. The shift plate 55 is deflected to drive the shift plate 55 to be embedded in the annular groove 53. At the same time, the pull rod 36 contacts and abuts against the C-shaped groove 56. At this time, the shift plate 55 is slid along the guide groove 54 to drive the pull rod 36 to move.

[0049] A push rod 57 is rotatably connected to the dial plate 55. One end of the push rod 57 passes through the drive shaft 11 and is fixedly connected to the protruding end of the electric push rod 38. When the electric push rod 38 is started, the push rod 57 is driven to move, thereby driving the dial plate 55 to move.

[0050] A slot 62 is provided at one end of the mounting rod 13, and a locking protrusion 58 is fixedly connected to a circular mounting plate 12. One end of the locking protrusion 58 is located in the slot 62 to limit the rotation of the mounting rod 13. A circular mounting plate 12 connected to the other end of the mounting rod 13 is threadedly connected to a bolt 59. After the bolt 59 is installed on the circular mounting plate 12, the head of the bolt 59 can be used to limit and fix the mounting rod 13 to prevent it from falling off.

[0051] The drive shaft 11 is provided with an arcuate slot 61. Once the selector plate 55 is aligned with the arcuate slot 61, it is deflected to disengage the annular slot 53 and clear the mounting rod 13. Specifically, when the hammer 2 of the device becomes worn due to long-term use and requires replacement, the upper portion of the housing is first removed to fully expose the internal structure of the device for ease of subsequent operation. Next, the electric push rod 38 is activated, driving the selector plate 55 to a position precisely aligned with the arcuate slot 61. The selector plate 55 is then manually deflected to disengage the annular slot 53 while clearing the mounting rod 13, preventing interference during subsequent operations. The bolts 59 securing the mounting rod 13 are then removed. Finally, the operator manually presses the pull rod 36, keeping it stable while slowly withdrawing the mounting rod 13. This allows the hammer 2 to be freely installed or removed.
