Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal material screening, and in particular to a medicinal material screening device for treating osteoporosis. Background Art

[0002] Osteoporosis is a common skeletal disease characterized by decreased bone density, thinning and brittle bones, and easy fractures. The commonly used treatment method is usually to use the Chinese herbal medicine Angelica dahurica to assist in the treatment of the disease. Because Angelica dahurica has the effects of promoting blood circulation, removing wind and dampness, and strengthening muscles and bones, it is widely used.

[0003] Regarding the screening of Chinese medicinal materials, a Chinese invention patent with patent number CN118080345B discloses a Chinese medicinal material sorting device, including: a screening cylinder, which has a cylinder for storing and sorting Chinese medicinal materials, and a bracket welded on the outer surface of the cylinder; a lower hopper, which is welded on the top of the cylinder; and a collision screening and sorting mechanism, which is used to stir and sort the Chinese medicinal materials and knock off the dirt on the Chinese medicinal materials. The invention stores Chinese medicinal materials in a screening cylinder, and uses a collision screening and sorting mechanism to stir the Chinese medicinal materials with dirt, so that the Chinese medicinal materials are turned and hit in the screening cylinder, and the dirt is shaken off the Chinese medicinal materials and scattered. Then, the discharge mechanism is used to release the Chinese medicinal materials and the separated dirt residues to the screening mechanism, and the screening mechanism is used to vibrate and screen the two, so as to achieve the sorting of Chinese medicinal materials, thereby improving the cleanliness of the sorting of Chinese medicinal materials and effectively reducing the cost of Chinese medicinal materials processing.

[0004] Although the above scheme improves the screening efficiency to a certain extent when screening Chinese medicinal materials, it is not suitable for the screening of Chinese medicinal materials with many roots such as Angelica dahurica in actual applications. The scope of application is relatively low. In addition, due to the fragile whisker structure of Chinese medicinal materials with many roots, the whole body is easily damaged under continuous and large-scale impacts, resulting in the breakage or damage of the whisker part, affecting the integrity of the Chinese medicinal materials. It may also be easily mistakenly screened into the soil, thereby causing the loss of medicinal materials. At the same time, it is difficult to thoroughly clean the soil or impurities on the small and complex root whisker structure. The entanglement and obstruction of the whisker part may also form a cleaning dead corner, resulting in residual soil and impurities, reducing the screening efficiency and screening effect. Summary of the invention

[0005] The present application solves the technical problems in the prior art of low scope of application, impact on the integrity of Chinese medicinal materials, increased loss of medicinal materials, poor cleaning effect and reduced screening efficiency by providing a medicinal material screening device for the treatment of osteoporosis.

[0051] The screening unit 200 includes a rotating column 210, a support rod 1 220, a support rod 230, a screening bag 240, a fixing block 250 and an abutment block 260;

[0052] The rotating column 210 is fixed below the output shaft of the motor 110 and is used to drive the screening bag 240 to rotate;

[0058] The screening cylinder 100 is made of stainless steel and has a dirt removal port 130 at its bottom for discharging soil and impurities that fall through the screen.

[0059] like Figure 4 and Figure 6 As shown, the inner wall of the screening cylinder 100 is evenly provided with four position slots 101 for positioning the rotating column 210 of the screening unit 200; four branch rods are arranged at the bottom of the rotating column 210, and the branch rods can be rotated into the position slots 101 of the screening cylinder 100 to realize the access of the screening unit 200, so that the rotating column 210 can be rotated to the position slots 101 and pulled out, and then the screening bag 240 can be disassembled and assembled.

[0060] In order to increase the service life of the device, preferably, the screening bag 240 is made of nylon or polyester fiber, which has good air permeability and wear resistance.

[0061] When the embodiment of the present application is actually running, the steps are as follows: first, the Chinese medicinal materials are loaded into the screening bag 240, and the screening bag 240 is fixed on the support rod 1 220 and the support rod 230, and then the screening unit 200 and the motor 110 are fixed in the screening cylinder 100; then, the motor 110 is started, and the motor 110 drives the rotating column 210 to rotate, thereby driving the screening bag 240 to rotate. At the same time, under the interference of the fixed block 250 and the interference block 260, the screening bag 240 and the interference block 260 continuously collide, and the Chinese medicinal materials are turned over and collided in the screening bag 240, and the soil and impurities are screened out through the mesh of the sieve; finally, after the screening is completed, the soil and impurities are discharged from the impurity removal port 130, the motor 110 is turned off, and the screening unit 200 and the motor 110 are removed from the screening cylinder 100, and the screening bag 240 is manually disassembled and the screened Chinese medicinal materials are taken out.

[0062] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0063] The invention solves the technical problems in the prior art of low application scope, influence on the integrity of Chinese medicinal materials, increased loss of medicinal materials, poor cleaning effect and reduced screening efficiency, and achieves the technical effects of expanding the application scope, ensuring the integrity of Chinese medicinal materials, reducing loss of medicinal materials, good cleaning effect and improved screening efficiency.

[0064] Embodiment 2: In order to reduce the splashing of soil after screening, so that the soil and impurities on the Chinese medicinal materials can be removed more effectively, and at the same time further improve the cleanliness and quality of the Chinese medicinal materials after screening, so as to improve the flexibility of the device, the present application proposes the following technical solutions for the above technical problems, specifically:

[0065] like Figure 1-Figure 4 As shown, the cleaning unit 300 is provided in plurality and is evenly fixed on the outside of the screening cylinder 100, including a support plate 310, an electric telescopic rod 320 and a blow pipe 330, which are used to further clean the sieved Chinese medicinal materials;

[0066] The support plate 310 is fixed on the outer wall of the upper part of the screening cylinder 100 and is used to support the electric telescopic rod 320;

[0067] The electric telescopic rod 320 is fixed on the support plate 310 and is used to adjust the inclination angle and position of the blowing pipe 330;

[0068] One end of the blowing pipe 330 is hinged to the electric telescopic rod 320, and the other end is hinged to the inside of the screening cylinder 100. The blowing pipe 330 moves up and down through the telescopic action of the electric telescopic rod 320, and performs directional blowing and cleaning on the Chinese medicinal materials in the screening bag 240 and the sieved soil and dust, while preventing the soil from flying.

[0069] The air outlet of the blowing pipe 330 is a cylindrical structure and is connected to an external power source through an external wire.

[0070] The blowing pipe 330 is used to blow and clean the Chinese medicinal materials and the dirt and dust in the screening bag 240, and is preferably driven by a DC motor. This is a prior art and will not be described in detail here.

[0071] During actual operation of this embodiment, the electric telescopic rod 320 is started, and the inclination angle and position of the blowing pipe 330 are adjusted so that the blowing pipe 330 is aligned with the Chinese medicinal materials in the screening bag 240 for directional blowing and cleaning.

[0072] The present application ensures that all parts of the Chinese medicinal materials can be effectively cleaned by moving the blow pipe 330 up and down, which helps to more thoroughly remove impurities and dust on the surface of the Chinese medicinal materials and improve the cleanliness of the Chinese medicinal materials; at the same time, through the telescopic effect of the electric telescopic rod 320, the inclination angle of the blow pipe 330 is adjusted, and then the direction of the blow port is adjusted, which can better separate Chinese medicinal materials and impurities of different sizes and weights, and improve the accuracy and efficiency of screening; the blow-type cleaning using the blow pipe 330 can concentrate the sieved soil and blow it out from the bottom outlet, effectively preventing the soil from flying, keeping the working environment clean, reducing the burden of cleaning work, and improving the overall working efficiency.

[0073] Embodiment 3: In order to reduce the clogging of the screen by soil during the screening process of medicinal materials and ensure the smooth progress of the screening process, the present application proposes the following technical solutions for the above technical problems, specifically:

[0074] like Figure 3-Figure 4 As shown, the support rod 1 220 is a flexible rubber rod, which is connected to the rotating column 210 by a hinged manner and can be deformed during rotation, so that the screening bag 240 is twisted during rotation and collision; the support rod 230 is a rigid rod, which is fixedly connected to the rotating column 210 to provide fixed support for the screening bag 240.

[0075] This embodiment improves the supporting structure of the screening bag 240 and changes the connection mode of the support rod 220 to a hinged connection, thereby realizing dynamic tension and twisting of the screening bag 240 during the screening process, and effectively improving the screening efficiency. The support rod 220 can rotate upward and tighten the screening bag 240 during the rotation process, so that the Chinese medicinal materials and the screen are in closer contact, and the medicinal materials are distributed more evenly on the screen, avoiding the screening effect being affected by uneven accumulation of the medicinal materials during the screening process. When the screening bag 240 is elongated, the relative movement between the Chinese medicinal materials increases, which helps to more thoroughly separate materials of different sizes and weights; at the same time, the screening bag 240 in close contact and tightened can reduce the gap between the medicinal materials and the screen, keep the screen holes unobstructed, improve the screening efficiency, prevent blockage, help reduce the omission of medicinal materials during the screening process, and ensure that the quality of the medicinal materials after screening meets the requirements.

[0076] Embodiment 4: In order to further improve the screening effect and the screening effect of collision screening, the present application proposes the following technical solutions for the above technical problems, specifically:

[0077] like Figure 2 , Figure 3 and Figure 7 As shown, the screening unit 200 further includes a lifting assembly 270 for tightening and beating the screening bag 240. The lifting assembly 270 is provided with multiple groups and is evenly fixed on the inner wall of the screening cylinder 100, including a fixed plate 271, a rotating plate 272, a movable plate 273 and an air bag 274;

[0078] The fixing plate 271 is fixed to the inner wall of the screening cylinder 100 and serves as a mounting base for the lifting assembly 270;

[0079] The rotating plate 272 is an elastic telescopic structure, placed at an angle, with its fixed end fixed to one end of the fixed plate 271 by a hinged manner, and its telescopic end connected to the movable plate 273;

[0080] The movable plate 273 is slidably connected inside the screening cylinder 100, and is used to cooperate with the rotating plate 272 and the support rod 220 to achieve the lifting of the support rod 220 during the rotation process, thereby achieving the beating and vibration of the screening bag 240;

[0081] The airbag 274 is fixed on the fixed plate 271 and is located between the movable plate 273 and the rotating plate 272, and is used to control the height of the movable plate 273 and the inclination of the rotating plate 272 by inflating and deflating air, thereby adjusting the lifting height of the support rod 220 and the screening bag 240.

[0082] The air bag 274 is a cylindrical structure and is placed vertically, and its interior is connected to the air pump through a pipeline.

[0083] The volume of the airbag 274 in the fully expanded state is 3-5 times of the original volume, and the lifting height of the support rod 1 220 in the expanded state of the airbag 274 is 3-5 times of the original volume.

[0084] The present application optimizes the screening process and adopts a dynamic slapping and vibrating screening method, which helps the Chinese medicinal materials to roll and disperse more fully in the screening bag 240, thereby improving the efficiency and uniformity of screening; the slapping and vibration can destroy the agglomeration and adhesion between the Chinese medicinal materials, making it easier to separate materials of different sizes and weights without manual intervention, thereby improving the screening efficiency. In addition, the tilt angle of the rotating plate 272 is controlled by controlling the air intake of the airbag 274, so as to realize the control of the lifting height of the lifting assembly 270 on the support rod 220, and the moving plate 273 is slidably connected to the inside of the screening cylinder 100 and supported by the airbag 274 and the rotating plate 272. When the support rod 220 rotates to the position of the lifting assembly 270, it goes up along the inclined surface of the rotating plate 272 and then passes through the moving plate 273, and then falls to realize the tightening and slapping of the screening bag 240.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
