Description

Technical Field

[0001] The utility model relates to the field of Chinese medicinal material processing equipment, in particular to a Chinese medicinal material pulverizer. Background Art

[0002] Traditional Chinese medicine grinders utilize intermittent grinding, with a crushing capacity ranging from 100g to 500g. This makes them ideal for laboratory applications in a variety of industries, including pharmaceuticals, food, chemicals, agriculture, research institutes, universities, and colleges, as well as for use in pharmacies, drug stores, clinics, and even homes. Traditional Chinese medicine grinders utilize high-speed rotating impact blades to achieve general pulverization of dry materials. These grinders consist of a stainless steel upper cover and a lower body, enclosed by a screw-type pulverizing chamber. A high-speed vertical motor drives the horizontally mounted pulverizing blades, which impact and shear the material. Because the pulverized material is agitated within a confined space, the pulverization is relatively uniform, but this also reduces the likelihood of residual material remaining within the confined space.

[0034] Traditional Chinese medicine pulverizers typically consist of a stainless steel upper cover and a lower crushing chamber, sealed with a screw-type seal. A high-speed vertical motor drives horizontally mounted pulverizing blades, which impact and shear the material. While the pulverized material is agitated within the enclosed space, the pulverization is relatively uniform, but the pulverized material is less likely to remain within.

[0035] Reference Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a Chinese medicine grinder, comprising: a grinding box 100, a grinding assembly 200, a grinding cover 300 and a cleaning assembly 400.

[0036] The crushing chamber 100 comprises a crushing chamber 110 with an opening at the top and an equipment chamber located below the crushing chamber 110. The equipment chamber communicates with the crushing chamber 110 and forms an installation passage. In this embodiment, the crushing chamber 100 is cylindrical in shape, enhancing the appearance of the crusher. The crushing chamber 110 is cylindrical with an annular inner circumference. The crushing chamber 100 can be integrally formed or comprised of separate, detachably connected chambers.

[0037] The crushing assembly 200 includes a crushing shaft 210 partially arranged in the crushing cavity 110 and a plurality of crushing blades 220 connected to the crushing shaft 210. The plurality of crushing blades 220 are arranged at the bottom of the crushing cavity 110 and are spaced apart along the circumferential direction of the crushing shaft 210. In this embodiment, the crushing assembly 200 further includes a motor 230 which is drivingly connected to the crushing shaft 210 to drive the crushing shaft 210 to rotate. The motor 230 is arranged in the equipment cavity and is shielded by the crushing box 100, so that the appearance of the crushing machine is more beautiful. As another embodiment, the crushing box 100 can only have the crushing cavity 110, and the motor 230 is directly exposed outside the crushing box 100. Part of the crushing shaft 210 is arranged in the equipment cavity, and the other part extends into the crushing cavity 110 from the installation channel and is connected with the crushing blades 220 in the crushing cavity 110 to drive the crushing blades 220 to rotate, thereby crushing the traditional Chinese medicinal materials in the crushing cavity 110. The number of the crushing blades 220 is four, and the four crushing blades 220 are arranged along the circumferential direction of the crushing shaft 210. Of course, the number of the crushing blades 220 can be less than four, such as three, or more than four, such as five.

[0038] The crushing cover 300 covers the top of the crushing box 100 and covers the opening. The crushing cover 300 directly covers the top of the crushing box 100 to close the crushing cavity 110. The crushing blades 220 crush the traditional Chinese medicinal materials in the closed space, which avoids the traditional Chinese medicinal materials from splashing and injuring people, and improves the crushing effect of the crushing blades 220 on the traditional Chinese medicinal materials. The crushing cover 300 can be fixedly connected with the crushing box 100 by a buckle or other fastening members to avoid the crushing cover 300 from shaking or separating from the opening of the crushing box 100. In this embodiment, the crushing cover 300 is disc-shaped.

[0039] The cleaning assembly 400 includes a cleaning shaft 410 and a cleaning member 420 connected to the cleaning shaft 410. The cleaning shaft 410 is rotatably connected to the pulverizing cover 300. One end of the cleaning shaft 410 is engaged with one end of the pulverizing shaft 210 so as to rotate with the pulverizing shaft 210. The cleaning member 420 has a first state and a second state. The cleaning member 420 is configured such that: in the first state, the cleaning member 420 is located within the pulverizing chamber 110 and contacts the inner wall of the pulverizing chamber 110. The cleaning member 420 and the pulverizing blades 220 are spaced apart along the circumference of the pulverizing shaft 210. In the second state, the cleaning member 420 is located outside the pulverizing chamber 110 or at the top of the pulverizing chamber 110. The cleaning shaft 410 is located at the center of the pulverizing cover 300 and is aligned with the pulverizing shaft 210 when the pulverizing cover 300 is closed with the pulverizing housing 100. The cleaning shaft 410 is rotatably connected to the crushing cover 300. When the crushing cover 300 is fixed, the cleaning shaft 410 can rotate under the drive of the crushing shaft 210 to drive the cleaning member 420 to rotate. The cleaning member 420 contacts the inner wall surface of the crushing chamber 110, and the cleaning member 420 can clean the inner wall surface of the crushing chamber 110 by rotating.

[0040] It is worth understanding that, in the process of crushing Chinese medicine by the Chinese medicine grinder, the cleaning member 420 is in the second state, and the crushing blades 220 will normally crush the Chinese medicinal materials in the crushing chamber 110. After crushing, the cleaning member 420 is changed from the second state to the first state, so that the cleaning member 420 contacts the inner wall surface of the crushing chamber 110, and the cleaning shaft 410 is engaged with the crushing shaft 210. When the crushing shaft 210 rotates, the cleaning shaft 410 rotates with the crushing shaft 210, and the cleaning member 420 connected to the cleaning shaft 410 will rotate together, and the cleaning member 420 and the crushing blades 220 rotate synchronously. The cleaning member 420 will not be disturbed by the crushing blades 220, so as to clean the crushing chamber 110, realize automatic cleaning, and be more convenient to use.

[0041] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the cleaning member 420 is detachably connected to the cleaning shaft 410, wherein the cleaning member 420 is configured as follows: when the cleaning member 420 is installed on the cleaning shaft 410, the cleaning member 420 is in a first state; when the cleaning member 420 is separated from the cleaning shaft 410, the cleaning member 420 is in a second state.

[0042] It is worth noting that the cleaning member 420 is detachably connected to the cleaning shaft 410. When the pulverizing chamber 110 needs to be cleaned, the cleaning member 420 is mounted on the cleaning shaft 410, placing the cleaning member 420 in a first state, thereby facilitating cleaning of the inner wall of the pulverizing chamber 110 driven by the pulverizing shaft 210. Furthermore, the cleaning member 420 can be placed integrally within the pulverizing chamber 110, providing a higher structural strength and better contact with the inner wall of the pulverizing chamber 110, thereby providing a better cleaning effect on the wall surface of the pulverizing chamber 110. Furthermore, the cleaning member 420 is prefabricated as a whole, and can conform to the axial cross-section of the pulverizing chamber 110, allowing the cleaning member 420 to more closely fit the wall surface of the pulverizing chamber 110, thereby improving the cleaning effect of the cleaning member 420 on the pulverizing chamber 110.

[0043] In this embodiment, the cleaning member 420 is connected to the cleaning shaft 410 via threads, or the cleaning member 420 is fixed to the cleaning shaft 410 via connectors such as pins or bolts, or the cleaning member 420 is fixed to the cleaning shaft 410 by snapping.

[0044] In some specific embodiments of the present invention, the cleaning member 420 is fixedly connected to the cleaning shaft 410 , and the cleaning member 420 is deformable to switch between a first state and a second state.

[0045] It is worth noting that the cleaning member 420 switches between a first state and a second state by deforming. In the second state, the cleaning member 420 is hidden within the pulverizing cover 300 and does not interfere with the pulverizing operation of the pulverizing blade 220. Furthermore, the cleaning member 420 is more convenient to use, as it does not need to be stored or installed separately.

[0046] In this embodiment, the cleaning member 420 is a three-link structure, wherein the ends of the three links are rotatably connected in sequence, and a limit portion is provided at the rotational position of two adjacent links, so that the links can only rotate by a preset angle, for example, only by 90°. When the three links are fully extended, two links are opposite each other, and another link is located between the two links and is rotatably connected to the two links. At this time, the cleaning member 420 is in a first state. When the three links are fully folded, the three links substantially overlap and fold into one body. At this time, the cleaning member 420 is in a second state. The limit portion can be a block provided on the side of the link, and the block extends along the rotation axis of the link. When the two links rotate, the two blocks between the two links will also rotate, limiting the connection to rotate only by a preset angle.

[0048] It is worth noting that the first connecting portion 411 and the second connecting portion 211 are engaged with each other to achieve the engagement between the cleaning shaft 410 and the crushing shaft 210, allowing the crushing shaft 210 to transmit power to the cleaning shaft 410, thereby driving the cleaning shaft 410 and the cleaning member 420 to rotate together. When the crushing cover 300 is separated from the crushing box 100, the cleaning shaft 410 and the crushing shaft 210 can be directly separated, making it easier to open the opening of the crushing box 100 to place Chinese medicinal materials or remove the crushed Chinese medicinal materials powder.

[0049] Reference Figure 2 As shown, in some specific embodiments of the present invention, one of the first connecting part 411 and the second connecting part 211 includes a connecting groove and a limiting protrusion provided on the inner circumference of the connecting groove, and the other one of the first connecting part 411 and the second connecting part 211 includes a connecting column and a limiting groove provided on the outer circumference of the connecting column and connected to the end face of the connecting column, the connecting column is inserted into the connecting groove, and the limiting protrusion is inserted into the limiting groove.

[0050] It is worth understanding that the connecting column is directly inserted into the connecting groove, and the limiting protrusion and the limiting groove are engaged to realize the limiting engagement of the first connecting part 411 and the second connecting part 211, so that the cleaning shaft 410 and the crushing shaft 210 can transmit power.

[0051] In this embodiment, the first connecting portion 411 comprises a connecting groove, which is provided on the end surface of the cleaning shaft 410, and a limiting protrusion is provided on the inner circumference of the connecting groove. The second connecting portion 211 comprises a limiting post, which is formed directly from the end of the crushing shaft 210 or from a shaft portion having different dimensions from the cleaning shaft 410. As another embodiment, the first connecting portion 411 can also be a limiting post, and the second connecting portion 211 can be a limiting groove.

[0052] Reference Figure 2 As shown, in some specific embodiments of the present invention, the cross section of the limiting groove perpendicular to the axial direction of the cleaning shaft 410 decreases in a direction away from the end surface of the connecting column.

[0053] In this embodiment, the limiting groove has a trumpet-shaped notch to guide the insertion of the limiting protrusion, so that the first connecting portion 411 and the second connecting portion 211 are more easily aligned, and the installation of the two is more convenient.

[0054] Reference Figure 1 and Figure 2As shown, in some specific embodiments of the present invention, the cleaning member 420 includes a connecting ring 421 and a support rod 422 connected to the connecting ring 421 , and the support rod 422 has a cleaning brush 423 on a side facing the inner wall of the pulverizing chamber 110 .

[0055] It is worth noting that the cleaning member 420 cleans the inner wall surface of the crushing chamber 110 through the cleaning brush 423 to improve the cleaning effect. The inner wall surface of the crushing chamber 110 includes an inner circumferential surface and a bottom surface. In this embodiment, the connecting ring 421 is annular, and the inner circumferential surface of the connecting ring 421 is provided with a thread. The outer circumferential surface of the cleaning shaft 410 is also provided with a thread. The connecting ring 421 is directly connected to the outer circumferential surface of the cleaning shaft 410 through the thread on the inner circumferential surface. The screw-in direction of the connecting ring 421 is the same as the rotation direction of the crushing shaft 210, that is, the locking rotation direction of the connecting ring 421 is the same as the rotation direction of the crushing shaft 210, so that when the crushing shaft 210 rotates, the connection between the connecting ring 421 and the cleaning shaft 410 is tighter and more reliable. As another embodiment, the connecting ring 421 may have a first through hole along its radial direction, and the cleaning shaft 410 may have a second through hole along its radial direction, and the second through hole may be provided with a thread. After the first through hole is aligned with the second through hole, the bolt is inserted into the first through hole and the second through hole in turn, and is fixed with the thread of the second through hole to realize the connection and locking of the connecting ring 421 and the cleaning shaft 410.

[0056] Specifically, the number of the first connection parts 411 and the second connection parts 211 are both four, and the second connection parts 211 correspond one-to-one to the four crushing blades 220. The number of the support rods 422 is also four. After the connecting ring 421 is threadedly connected to the cleaning shaft 410, the support rod 422 is exactly located in the middle position of the two first connection parts 411 along the circumferential direction of the cleaning shaft 410, so that after the crushing cover 300 and the crushing box 100 are installed, the support rod 422 is exactly located in the middle position of the two crushing blades 220 along the circumferential direction of the cleaning shaft 410, and the support rod 422 does not interfere with the crushing blades 220.

[0057] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the support rod 422 includes a peripheral wall cleaning rod and a bottom wall cleaning rod.

[0058] It is worth understanding that the support rod 422 cleans the inner circumference of the crushing chamber 110 through the peripheral wall cleaning rod, and cleans the bottom surface of the crushing chamber 110 through the bottom wall cleaning rod, so that all wall surfaces of the crushing chamber 110 are cleaned, thereby improving the cleaning effect of the crushing chamber 110.

[0059] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the peripheral wall of the crushing chamber 110 is annular.

[0060] In the embodiment, the bottom surface of the pulverizing cavity 110 can be a plane, and the pulverizing cavity 110 is in a cylindrical shape; the bottom surface of the pulverizing cavity 110 can also be an inclined surface; or the bottom surface of the pulverizing cavity 110 can also be a conical surface, which can be a funnel-shaped conical surface or an inverted funnel-shaped conical surface.

[0061] Referring to Figure 1 With Figure 2 As shown in the drawings, in some specific embodiments of the present application, the pulverizing cover 300 is provided with a water injection opening 310 which is in communication with the pulverizing cavity 110 and the outside.

[0062] It is worth understanding that the user can connect the water injection opening 310 with a water source outside to inject a cleaning solution into the pulverizing cavity 110, and the cleaning solution can be water or other solutions with cleaning effect. After the water injection opening 310 is added, the rotation of the cleaning member 420 drives the water flow to rotate, so that the traditional Chinese medicine powder in the pulverizing cavity 110 is subjected to the cleaning force of the cleaning brush 423 on the cleaning member 420 and the centrifugal force of the water flow. Under the joint action of multiple forces, the traditional Chinese medicine powder in the pulverizing cavity 110 is thoroughly cleaned, and the cleaning effect of the pulverizing cavity 110 is better. After cleaning is completed, the pulverizing cover 300 is opened, and the cleaning solution and the traditional Chinese medicine powder mixed in the cleaning solution can be poured out, thereby improving the cleaning effect of the pulverizing cavity 110.

[0063] In the embodiment, the water injection opening 310 is covered with a water injection cover to close the water injection opening 310. When it is needed to use, the water injection cover can be directly opened to inject a cleaning solution into the pulverizing cavity 110.

[0064] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled in the art without departing from the purpose of the present application.
