Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of Polygonum multiflorum production equipment, and in particular to a cleaning and screening device for Polygonum multiflorum production. Background Technology
[0002] Polygonum multiflorum, a traditional Chinese medicine, holds an important place in ancient medicine due to its effects of tonifying the liver and kidneys, darkening hair, and moistening the intestines to relieve constipation. Modern research has further confirmed its pharmacological effects in anti-aging and lowering blood lipids, making it an important medicinal material in modern health care and treatment.
[0003] Traditional methods of cleaning Polygonum multiflorum mainly rely on manual operation on a cleaning workbench. This method has many limitations. First, the speed of manual cleaning is relatively slow, which is difficult to meet the needs of large-scale production. Second, the precision of manual operation is limited, and it is often impossible to completely separate impurities such as stones and soil attached to the surface of Polygonum multiflorum, resulting in poor cleaning effect.
[0004] Therefore, this utility model provides a cleaning and screening device for the production of Polygonum multiflorum. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cleaning and screening device for the production of Polygonum multiflorum.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning and screening device for the production of Polygonum multiflorum, comprising;
[0007] Clean the cabinet;
[0008] Drying assembly; the drying assembly includes an industrial heater fixedly connected to the cleaning chamber, and a dispersion tube fixedly connected to the output end of the industrial heater;
[0009] Agitation assembly; the agitation assembly includes a base plate fixedly connected to the bottom of the interior of the cleaning tank, a motor installed at the bottom of the base plate, agitation columns rotatably connected to both sides of the interior of the cleaning tank, a rotating wheel fixedly connected to the bottom of the agitation column, a belt sleeved on the outer side of the two rotating wheels, and an agitation belt fixedly connected to the outer side of the agitation column.
[0010] Conveying assembly; the conveying assembly includes a mounting frame fixedly connected to a base plate, cylinders fixedly connected to both sides of the interior of the mounting frame, a grid frame slidably connected to the drive end of the cylinders, a limit post rotatably connected to one side of the grid frame, and sliding grooves provided on both sides of the interior of the mounting frame.
[0011] In one preferred embodiment, the bottom end of one of the agitating columns is fixedly connected to a motor.
[0012] In one preferred embodiment, the bottom end of one side of the rotating wheel is fixedly connected to the motor, and the bottom end of the other side of the rotating wheel is rotatably connected to the inside of the cleaning tank.
[0013] In a preferred embodiment, the outer side of the limiting post is slidably connected to the mounting bracket via a sliding groove.
[0014] In a preferred embodiment, a fan is installed at one end of the interior of the cleaning chamber, and a conveyor belt is installed on the side of the interior of the cleaning chamber near the fan.
[0015] In a preferred embodiment, both ends of the mounting bracket are fixedly connected to the inside of the cleaning chamber.
[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0017] This invention involves placing Polygonum multiflorum (He Shou Wu) into the cleaning chamber, starting the motor, and rotating the stirring column and belt. The stirring belt increases the contact area with the Polygonum multiflorum, ensuring thorough agitation and effective cleaning of all parts. After cleaning, the cylinder starts, and the grid frame moves vertically along the slide groove on the mounting frame via the limiting column. When it reaches the top of the slide groove, one end of the grid frame rotates and connects with the limiting column, and the cylinder continues to push, moving the other end upwards to transport the Polygonum multiflorum onto the conveyor belt. Once on the conveyor belt, an industrial heater provides heat, and a dispersion tube evenly distributes the heat into the cleaning chamber. A fan rotates to generate airflow, accelerating the evaporation of surface moisture from the Polygonum multiflorum, while the conveyor belt transports it from one end to the other. This design allows for rapid cleaning of Polygonum multiflorum and enables fast and uniform drying after cleaning. This reduces surface moisture and mold problems caused by excessive moisture. Compared to traditional manual cleaning methods, it can more thoroughly remove or eliminate surface impurities, improving the quality of the cleaned Polygonum multiflorum. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figure 1 - Figure 2 As shown, this embodiment provides a technical solution: a cleaning and screening device for Polygonum multiflorum production, comprising:
[0029] Clean the box 1;
[0030] Drying assembly 2; Drying assembly 2 includes an industrial heater 21 fixedly connected to the cleaning chamber 1, a dispersion tube 22 fixedly connected to the output end of the industrial heater 21, a fan 23 installed at one end inside the cleaning chamber 1, and a conveyor belt 24 installed inside the cleaning chamber 1 on the side near the fan 23.
[0031] The cleaning chamber 1 serves as the main frame structure of the entire device, used to house and secure other components. The inlet of the cleaning chamber 1 is designed with an incline to facilitate the entry of Polygonum multiflorum into the device for cleaning. An outlet is located on one side of the chamber for emptying dirty water after use. An industrial heater 21 provides a heat source to heat and dry the cleaned Polygonum multiflorum. Heating effectively removes surface moisture, making it easier for subsequent screening and processing, while also reducing problems such as mold growth caused by excessive moisture. A dispersion tube 22 is connected to the output of the industrial heater 21, evenly distributing the heat generated by the heater into the cleaning chamber. Inside the body 1, the distribution and design of the dispersion tubes 22 can create a relatively uniform temperature field within the chamber, ensuring that the Polygonum multiflorum is heated evenly during the drying process, thereby improving drying efficiency and quality. The fan 23 is installed at one end inside the cleaning chamber 1 to generate airflow. During the drying process, the airflow generated by the fan 23 can accelerate the evaporation of moisture on the surface of the Polygonum multiflorum, increasing the drying speed. The conveyor belt 24 is installed inside the cleaning chamber 1 on the side close to the fan 23 to carry and transport the Polygonum multiflorum. The conveyor belt 24 can transport the cleaned Polygonum multiflorum from one end to the other, allowing it to be evenly subjected to heat and airflow during the drying process.
[0032] like Figure 1 - Figure 3 As shown, the agitation assembly 3 includes a base plate 31 fixedly connected to the bottom of the interior of the cleaning tank 1. A motor 32 is installed at the bottom of the base plate 31. Agitation columns 33 are rotatably connected to both sides of the interior of the cleaning tank 1. The bottom of one agitation column 33 is fixedly connected to the motor 32. A rotating wheel 34 is fixedly connected to the bottom of the agitation column 33. The bottom of one rotating wheel 34 is fixedly connected to the motor 32, and the bottom of the other rotating wheel 34 is rotatably connected to the interior of the cleaning tank 1. A belt 35 is sleeved on the outer side of the two rotating wheels 34. An agitation belt 36 is fixedly connected to the outer side of the agitation column 33.
[0033] The base plate 31 is used to install and fix the motor 32, providing stable support and a mounting platform for the motor 32. The motor 32 serves as the power source for the agitation assembly 3. The rotation of the motor 32 drives the agitation column 33 to rotate, thereby agitating the Polygonum multiflorum. The bottom end of one agitation column 33 is fixedly connected to the motor 32 and rotates under the drive of the motor 32. The rotation of the agitation column 33 drives the agitation belt 36 to move, agitating the Polygonum multiflorum and ensuring that it is fully turned over in the cleaning tank 1. The bottom end of one rotating wheel 34 is fixedly connected to the motor 32, and the bottom end of the other rotating wheel 34 is rotatably connected to the cleaning tank 1. Inside the washing tank 1, the rotating wheel 34, in cooperation with the belt 35, transmits the rotational motion of the motor 32 to the stirring column 33 on the other side, so that the stirring columns 33 on both sides rotate synchronously, ensuring the stable operation of the stirring belt 36. The outer sides of the two rotating wheels 34 are fitted with belts 35, which transmit the power of the motor 32 to the stirring column 33 on the other side through the transmission action of the belts 35, so that the stirring columns 33 on both sides rotate synchronously. The stirring belt 36 rotates under the drive of the stirring column 33, directly contacting the Polygonum multiflorum, stirring and turning the Polygonum multiflorum. The design of the stirring belt 36 can increase the contact area with Polygonum multiflorum and improve the stirring effect.
[0034] like Figure 1 - Figure 4 As shown, the conveying assembly 4 includes a mounting frame 41 fixedly connected to the base plate 31. Both ends of the mounting frame 41 are fixedly connected to the inside of the cleaning tank 1. Cylinders 42 are fixedly connected to both sides of the inside of the mounting frame 41. A grid frame 43 is slidably connected to the driving end of the cylinders 42. A limit post 44 is rotatably connected to one side of the grid frame 43. The outer side of the limit post 44 is slidably connected to the mounting frame 41 through a sliding groove 45. Sliding grooves 45 are provided on both sides of the inside of the mounting frame 41.
[0035] Mounting frame 41 is fixedly connected to base plate 31, and its two ends are fixedly connected to the inside of cleaning chamber 1, providing stable support and mounting platform for conveying assembly 4. Cylinders 42 are fixedly connected to both sides inside mounting frame 41. The drive end of cylinder 42 is slidably connected to grid frame 43. Through the extension and retraction of cylinder 42, grid frame 43 can be driven to slide on mounting frame 41, thus conveying Polygonum multiflorum onto conveyor belt 24. The grid structure of grid frame 43 can separate impurities and small particles from Polygonum multiflorum, and when pushed to the top… When the end is reached, the continuous push of the cylinder 42 rotates one end of the grid frame 43 onto the mounting frame 41, and the other end is flipped by the pushing force, thereby realizing the conveying of Polygonum multiflorum. The function of the limiting post 44 is to limit the movement range of the grid frame 43, ensure that the grid frame 43 remains stable during the sliding process, and prevent it from falling off the mounting frame 41. The outer side of the limiting post 44 is slidably connected to the mounting frame 41 through the sliding groove 45. The sliding groove 45 provides a track for the sliding of the limiting post 44, ensuring that the movement of the limiting post 44 and the grid frame 43 is smooth and accurate.
[0036] like Figure 1 - Figure 4 As shown, during use: The Polygonum multiflorum is placed into the cleaning chamber 1, then the motor 32 is started. The rotation of the stirring column 33 and the stirring belt 36 agitates and tumbles the Polygonum multiflorum, ensuring it is thoroughly cleaned throughout the chamber. The stirring belt 36 is designed to increase the contact area with the Polygonum multiflorum, improving the agitation effect. When the Polygonum multiflorum is clean, the cylinder 42 is activated, causing the grid frame 43 to slide along the slide groove 45 via the limiting column 44, achieving vertical movement. When it reaches the top of the slide groove 45, one end of the grid frame 43 rotates with the limiting column 44. As the cylinder 42 continues to push, the other end of the grid frame 43 will move upward, thereby conveying the Polygonum multiflorum on the grid frame 43 to the fan 23 for drying. Subsequently, the industrial heater 21 provides a heat source. By connecting to the output end of the industrial heater 21, the heat generated by the heater is evenly distributed inside the cleaning chamber 1. Then, the rotation of the fan 23 generates airflow. During the drying process, the airflow generated by the fan 23 can accelerate the evaporation of moisture on the surface of the Polygonum multiflorum and increase the drying speed. The conveyor belt 24 can transport the cleaned Polygonum multiflorum from one end to the other end, so that it can be evenly subjected to the effects of heat and airflow during the drying process.
[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
