Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cleaning devices for Chinese medicinal materials, specifically, to a cleaning device for Chinese medicinal materials. Background Technology
[0002] Cleaning of Chinese medicinal materials generally refers to the process of washing away dirt and other impurities adhering to the surface of Chinese medicinal materials, so as to avoid affecting the quality and safety of medicines due to impurities on the surface of the medicinal materials during the pharmaceutical process.
[0003] Currently, most Chinese medicinal herb cleaning devices use drums as raw material containers, with water spray components and spiral conveyor plates inside the drums to ensure the herbs reach designated positions after rinsing and completing the cleaning process. This method relies primarily on the inertial force generated by the drum's rotation to tumble the herbs inside, ensuring uniform cleaning of their outer surfaces. However, in actual cleaning processes, large quantities of herbs may be crammed into the drum. The herbs collide and overlap under the drum's rotation, making it difficult for some herbs to tumble or even be properly cleaned by the water flow. This results in incomplete cleaning and requires multiple washes. Utility Model Content
[0004] This utility model proposes a device for cleaning raw materials of Chinese medicinal herbs, which solves the problem of uneven cleaning of raw materials of Chinese medicinal herbs in related technologies.
[0005] The technical solution of this utility model is as follows:
[0006] A device for cleaning raw materials of Chinese medicinal herbs includes a frame, a drum, and several spray pipes for supplying water to the inside of the drum. The drum is rotatably connected to the frame. The inside of the drum has a spiral conveying plate. The drum is provided with an adjusting plate, which passes through the drum along the axial direction of the drum and is fixedly connected to the frame. There is a gap between the spiral conveying plate and the end of the adjusting plate that is close to the spiral conveying plate. Each spray pipe is symmetrically distributed with the adjusting plate as the center.
[0007] Furthermore, the drum is provided with a plurality of auxiliary conveying plates, each of which is located between adjacent spiral rings of the spiral conveying plate, and the two ends of the auxiliary conveying plates in the axial direction of the drum are respectively fixedly connected to adjacent spiral rings of the spiral conveying plate.
[0008] Furthermore, the adjacent auxiliary conveyor plates are staggered along the circumferential direction of the roller.
[0009] Furthermore, the adjusting plate is inclinedly disposed inside the drum.
[0010] Furthermore, the adjusting plate has a first anti-scratch body at both ends in the radial direction of the roller, and each of the auxiliary conveying plates has a second anti-scratch body at the end close to the adjusting plate. Both the first and second anti-scratch bodies are arc-shaped structures.
[0011] Furthermore, the adjusting plate includes a plate frame and a plate body. The plate frame is fixedly connected to the machine frame, and the plate body is fixedly connected to the plate frame. The plate body is made of an elastic material.
[0012] Furthermore, the plate frame is symmetrically distributed around the plate, and the plate frame has a "U" shaped structure when projected onto the horizontal plane.
[0013] The working principle and beneficial effects of this utility model are as follows:
[0014] The roller in this invention is equipped with an adjusting plate inside. There is a gap between the adjusting plate and the spiral conveying plate, that is, there is a gap between the end of the adjusting plate that is close to the spiral conveying plate and the spiral inner diameter of the spiral conveying plate, so as to avoid interference between the spiral conveying plate and the adjusting plate when the roller rotates.
[0015] By cooperating with the adjusting plate and the screw conveyor plate, the gap between the screw conveyor plate and the adjusting plate becomes a channel for the movement of medicinal materials. This limits the amount of medicinal materials that move with the rotation of the drum, and avoids the situation where the medicinal materials overlap due to the excessive number of moving medicinal materials, resulting in inadequate cleaning of each medicinal material or uneven cleaning of individual medicinal materials.
[0016] Furthermore, both sides of the regulating plate are equipped with spray pipes to ensure that both herbs that do not pass through the gap between the regulating plate and the spiral conveyor plate and herbs that do pass through the gap between the regulating plate and the spiral conveyor plate can be rinsed by water flow, thus avoiding the presence of the regulating plate affecting the normal cleaning effect of herbs inside the drum.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0030] Example 1
[0031] like Figure 1 , Figure 3 As shown in the figure, this embodiment proposes a Chinese herbal medicine raw material cleaning device, which mainly includes a frame 1, a drum 2, and several spray pipes 3 for supplying water to the inside of the drum 2. The drum 2 is rotatably connected to the frame 1. The inside of the drum 2 has a spiral conveying plate 21, which is fixedly connected to the drum 2. The spiral axis of the spiral conveying plate 21 is concentrically set with the rotation axis of the drum 2, so that the herbs inside the drum 2 can gradually move along the spiral line as the drum 2 rotates, thereby completing the conveying of the herbs while cleaning them.
[0032] The drum 2 is equipped with an adjusting plate 4, which extends through the drum 2 along its axial direction. This means the adjusting plate 4 is distributed along the rotation axis of the drum 2, ensuring its adjustment range covers the entire drum 2 and regulates the medicinal materials inside. A gap exists between the end of the spiral conveyor plate 21 and the end of the adjusting plate 4 closest to it. This gap divides the interior of the drum 2 into two spaces, while the gap between the end of the adjusting plate 4 closest to the spiral conveyor plate 21 and the spiral inner diameter of the spiral conveyor plate 21 serves as a channel connecting the two spaces. The medicinal materials inside the drum 2 gradually move as the drum 2 rotates, entering the other space. However, due to the obstruction of the adjusting plate 4, the number of medicinal materials entering the other space at one time is limited. The adjusting plate 4 sequentially separates a small amount of medicinal materials, which tumble in the other space as the drum 2 rotates, receiving uniform rinsing from the water flow of the spray pipe 3. Because the number of medicinal materials entering this space is limited, the phenomenon of overlapping and obstructing the water flow is effectively avoided, ensuring the cleaning effect of this embodiment.
[0033] Meanwhile, considering that the adjusting plate 4 will come into contact with the medicinal materials inside the adjusting roller 2, in order to ensure the stability of the adjusting plate 4 inside the roller 2, the adjusting plate 4 is fixedly connected to the frame 1. It is preferable to weld several connecting rods on the frame 1 and weld the adjusting plate 4 to each connecting rod to prevent the adjusting plate 4 from shaking due to contact with the medicinal materials and improve the stability of operation in this embodiment.
[0034] Each spray pipe 3 is symmetrically and evenly distributed around the adjusting plate 4, ensuring that both medicinal materials that do not pass through the gap between the adjusting plate 4 and the spiral conveyor plate 21 and those that do pass through the gap between the adjusting plate 4 and the spiral conveyor plate 21 can be rinsed by water flow, thus avoiding the presence of the adjusting plate 4 affecting the normal cleaning effect of the medicinal materials inside the drum 2.
[0035] To ensure the efficiency of the medicinal materials inside roller 2 passing through the gap between the adjusting plate 4 and the screw conveyor plate 21, such as... Figures 3-6 As shown, in this embodiment, the roller 2 is provided with several auxiliary conveying plates 5. Each auxiliary conveying plate 5 is located between each adjacent spiral ring of the spiral conveying plate 21. Each auxiliary conveying plate 5 rotates together with the roller 2. When the auxiliary conveying plate 5 comes into contact with the medicinal material, it will push the medicinal material forward, so that the medicinal material in the roller 2 no longer relies indirectly on the rotation of the roller 2 to move, but can move directly by the rotation of the roller 2. This improves the separation efficiency of the medicinal material inside the roller 2 and more effectively sends each medicinal material into the next space in batches, ensuring the cleaning effect of this embodiment.
[0036] Furthermore, when the angle between the central axis of the auxiliary conveyor plate 5 and the horizontal plane is greater than or equal to 90°, the medicinal materials pushed by the auxiliary conveyor plate 5 will fall off by themselves under the influence of gravity (detach from the auxiliary conveyor plate 5), allowing the medicinal materials to flip over and ensuring that all sides of the medicinal materials can be washed by the water flow.
[0037] The auxiliary conveyor plate 5 is also left with a gap at one end close to the adjusting plate 4 to prevent interference between the auxiliary conveyor plate 5 and the adjusting plate 4 during the rotation of the roller 2, thus ensuring the safety of operation in this embodiment.
[0038] The auxiliary conveying plate 5 is fixedly connected to the adjacent screw rings of the spiral conveying plate 21 at both ends of the roller 2 in the axial direction to avoid the auxiliary conveying dead angle between the auxiliary conveying plate 5 and the spiral conveying plate 21 and to ensure the stability of the auxiliary conveying.
[0039] The adjacent auxiliary conveying plates 5 are staggered along the circumferential direction of the roller 2, that is, each auxiliary conveying plate 5 is staggered along the spiral line of the spiral conveying plate 21. When the medicinal materials inside the roller 2 move along the spiral conveying plate 21 under the influence of the rotation of the roller 2 and enter the next pitch (between adjacent spiral rings), they can be directly supported by the auxiliary conveying action of the auxiliary conveying plate 5 in that pitch. This allows the medicinal materials in this embodiment to be continuously in a tumbling state, so that all surfaces of the medicinal materials can be continuously washed by the water flow.
[0040] like Figure 2 As shown, in this embodiment, the adjusting plate 4 is inclinedly disposed inside the roller 2, so that when the medicinal materials pushed by the auxiliary conveying plate 5 fall under the influence of gravity, they will fall onto the adjusting plate 4 and roll due to gravity, thus generating multiple flips until the medicinal materials on the adjusting plate 4 re-contact the roller 2; and, due to the blocking effect of the adjusting plate 4, the medicinal materials that begin to fall under the influence of gravity are divided into two segments, reducing the impact force of each fall and reducing the damage to the medicinal materials; at the same time, because the adjusting plate 4 is inclined, the rolling behavior of the medicinal materials on the adjusting plate 4 and the position where the medicinal materials re-contact the roller 2 can be predicted more accurately, so that this embodiment can better plan the subsequent medicinal material cleaning steps.
[0041] The adjusting plate 4 has a first anti-scratch body 41 at both ends of the roller 2 in the radial direction, and each auxiliary conveying plate 5 has a second anti-scratch body 51 at the end close to the adjusting plate 4. Both the first anti-scratch body 41 and the second anti-scratch body 51 are arc-shaped structures to prevent sharp corners on the adjusting plate 4 and each auxiliary conveying plate 5 from being scratched by the auxiliary conveying plate 5 or the adjusting plate 4 when the medicinal materials come into contact with the adjusting plate 4 and each auxiliary conveying plate 5, or when they pass through the adjusting plate 4 under the pushing action of the auxiliary conveying plate 5, thus ensuring the safety of the medicinal materials.
[0042] Example 2
[0043] like Figures 7-8As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that: the adjustment plate 4 includes a plate frame 42 and a plate 43. The plate frame 42 is fixedly connected to the frame 1. The fixed connection between the plate frame 42 and the frame 1 is preferably achieved by setting a number of connecting rods between the two. The two ends of each connecting rod are welded to the plate frame 42 and the frame 1 respectively, to ensure the stability of the support part of the adjustment plate 4 in this embodiment.
[0044] The plate body 43 is fixedly connected to the plate body frame 42. The plate body 43 is located in the roller 2, so that when the medicinal material in this embodiment comes into contact with the adjustment plate 4, it mainly contacts the plate body 43 part of the adjustment plate 4.
[0045] Furthermore, to prevent the auxiliary conveyor plate 5 from being pinched and broken by the adjusting plate 4 due to excessive stacking of medicinal materials during auxiliary conveying, the plate 43 is made of elastic material. This allows the plate 43 to deform to a certain extent when it comes into contact with the medicinal materials conveyed by the auxiliary conveyor plate 5, thereby preventing damage to the medicinal materials. Moreover, when medicinal materials fall due to gravity and come into contact with the plate 43, the elasticity of the plate 43 can cushion the impact force generated when the medicinal materials fall, further ensuring the safety of the medicinal materials.
[0046] Since the plate 43 is made of elastic material, the preferred method for fixing the plate 43 to the plate frame 42 is bonding or other methods commonly used for fixing elastic materials, which facilitates the installation of the plate 43 onto the plate frame 42.
[0047] In this embodiment, the elastic material constituting the plate 43 is preferably a deformable elastic material such as silicone, to ensure that the plate 43 can quickly deform under force when it comes into contact with the medicinal material, avoid the medicinal material, and prevent the medicinal material from being damaged.
[0048] like Figure 9 As shown, in this embodiment, the plate frame 42 is symmetrically distributed around the plate 43, and the plate frame 42 has a "U" shaped structure in the horizontal projection plane. That is, the plate frame 42 has an opening for the plate 43 to be embedded and installed, so that there are multiple contact surfaces and connection surfaces between the plate 43 and the plate frame 42, which fully ensures the connection strength between the plate 43 and the plate frame 42.
[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
