Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material processing technology for Polygonatum tea, specifically a raw material drying device for Polygonatum tea processing. Background Technology
[0002] Polygonatum tea is a health-promoting tea made primarily from Polygonatum sibiricum. It has the effects of replenishing qi and nourishing yin, strengthening the spleen and moistening the lungs, and benefiting the kidneys and replenishing essence. It is often used to improve fatigue, enhance immunity, regulate blood sugar, and delay aging. Its preparation process includes selecting raw materials (preferably plump and fleshy ginger-shaped Polygonatum sibiricum), washing and slicing, nine steaming and nine sun-drying (traditional processing to remove irritation and enhance efficacy), drying and sterilization, and finally blending it with green tea or black tea, or packaging it separately into tea bags. Polygonatum tea combines the characteristics of both medicine and food, making it suitable for daily conditioning for sub-healthy people. However, attention should be paid to the suitability of the individual's constitution and the amount consumed. When drying Polygonatum sibiricum or some of its raw materials, in order to improve the drying efficiency, it is necessary to manually stir it at regular intervals, which is time-consuming and laborious. Therefore, some drying devices have been equipped with automatic stirring mechanisms.
[0003] For example, the patent with authorization announcement number CN222703737U discloses a raw material drying device for processing Polygonatum tea. When in use, the electric slide rail is powered by an external power source, which moves the sliding block on the electric slide rail. In turn, the sliding block moves the device frame, thus automatically adjusting the position of the device frame. Through the coordinated arrangement of servo motor, transmission rod, hydraulic rod and gripper, when in use, the hydraulic rod is activated to adjust the gripper to a suitable height. Then, the servo motor is powered by an external power source, which drives the rotating rod to rotate the hydraulic rod. In turn, the hydraulic rod drives the gripper to rotate, thus mixing the raw materials. However, there are still some problems.
[0004] The aforementioned stirring mechanism shares the same shortcomings as some existing stirring mechanisms: after stirring, materials and water droplets may adhere to the outside of the gripper. When the gripper moves to the next set of materials for stirring, it will carry the adhered materials with it. This will disrupt the expected drying cycle when the drying cycle is different or the types of materials are different. The mixing of materials will also affect the subsequent processing quality of Polygonatum tea. Utility Model Content
[0005] To address the aforementioned issues, this application provides a raw material drying device for processing Polygonatum odoratum tea, which solves the problem of the material adhering to its outer surface not being cleaned in time after being turned and stirred.
[0006] A raw material drying device for processing Polygonatum odoratum tea includes a workbench, a linear displacement component installed on the top of the workbench, multiple electric push rods installed in the middle of the linear displacement component, a piston plate fixedly installed on the telescopic end of the electric push rod, an air chamber slidably installed around the piston plate, an air hole penetrating the top of the air chamber, and multiple air nozzles fixedly installed on the outer side of the bottom of the air chamber, with the air nozzles and air holes connected by pipes.
[0007] Furthermore, the linear displacement assembly includes a motor, which is fixedly mounted on the top of the worktable. A lead screw is fixedly mounted on the output end of the motor, and the end of the lead screw away from the motor is rotatably mounted on the top of the worktable.
[0008] Furthermore, a sliding plate is fitted on the outer side of the lead screw, and an electric push rod is fixedly installed on the top of the sliding plate, with the telescopic end of the electric push rod sliding through the sliding plate.

[0010] Furthermore, a motor is fixedly installed at the bottom of the piston plate, and a pawl is fixedly installed at the output end of the motor.
[0011] Furthermore, multiple drying boxes are installed on the top of the workbench.
[0012] The beneficial effects of this utility model are as follows:
[0013] The present invention discloses a raw material drying device for processing Polygonatum odoratum tea. After the material is stirred, the motor stops rotating, the claw is located directly below the air nozzle, the extension end of the electric push rod shortens, driving the piston plate and the claw to move upward.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0023] like Figures 1-5 As shown, this utility model embodiment provides a raw material drying device for processing Polygonatum odoratum tea, including a workbench 1. Multiple drying boxes 10 are installed on the top of the workbench 1 for placing materials to be dried. A linear displacement assembly 2 is installed on the top of the workbench 1 to move the claw 9 to the working area. Multiple electric push rods 3 are installed in the middle of the linear displacement assembly 2 to move the claw 9 vertically, contacting and agitating the materials. A piston plate 6 is fixedly installed at the telescopic end of the electric push rod 3. An air chamber 4 is slidably installed around the piston plate 6, and the piston plate 6 is used to change the internal pressure of the air chamber 4. The air chamber 4 has an air hole 5 through the top, and multiple air nozzles 8 are fixedly installed on the outer bottom of the air chamber 4. The air nozzles 8 are connected to the air hole 5 through pipes. A motor 7 is fixedly installed on the bottom of the piston plate 6, and a claw 9 is fixedly installed on the output end of the motor 7. The claw 9 includes multiple staggered claw hooks. The air nozzles 8 are located directly above the claw hooks of the claw 9. The motor 7 is used to drive the claw 9 to rotate and stir the material. The air nozzles 8 and the claw 9 correspond one-to-one. When the motor 7 stops rotating, the claw 9 is located directly below the air nozzles 8. It can be controlled by program settings and is a relatively mature existing technology.
[0024] In this embodiment, the telescopic end of the electric push rod 3 extends, causing the piston plate 6 and the claw 9 to move downwards. The motor 7 rotates, causing the claw 9 to rotate and stir the material. The piston plate 6 moves downwards, causing the pressure inside the air chamber 4 to decrease. Outside air enters the air chamber 4 through the jet nozzle 8, pipe, and air hole 5.
[0025] After the mixing is complete, the motor 7 stops rotating, the claw 9 is located directly below the jet nozzle 8, the telescopic end of the electric push rod 3 shortens, driving the piston plate 6 and the claw 9 to move upward, the pressure inside the air chamber 4 increases, and the internal air is sprayed from the air hole 5, the pipe and the jet nozzle 8 onto the claw 9. As the claw 9 moves upward, the airflow blows from top to bottom onto the claw 9, causing the material and water droplets adhering to its outside to fall off, without affecting the subsequent mixing of materials.
[0026] Specifically, the linear displacement component 2 includes a motor 23, which is fixedly installed on the top of the worktable 1. A lead screw 22 is fixedly installed at the output end of the motor 23, and the end of the lead screw 22 away from the motor 23 is rotatably installed on the top of the worktable 1.
[0027] Specifically, a sliding plate 24 is fitted on the outer side of the lead screw 22, and an electric push rod 3 is fixedly installed on the top of the sliding plate 24. The lead screw 22 is used to drive the sliding plate 24 to move linearly, thereby driving the pawl 9 to move to the working area. The telescopic end of the electric push rod 3 slides through the sliding plate 24.
[0028] In this embodiment, the staff places the materials to be dried one by one into the corresponding drying box 10. When it is necessary to stir, the motor 23 rotates, which drives the lead screw 22 to rotate, and then drives the sliding plate 24 to slide, moving the claw 9 to directly above the drying box 10 that needs to be stirred.
[0029] Specifically, a limiting rod 21 is slidably installed at the end of the sliding plate 24 away from the lead screw 22 to limit the movement trajectory of the sliding plate 24, and the end of the limiting rod 21 is fixedly installed on the top of the workbench 1.
[0030] Specific working methods:
[0031] The staff places the materials to be dried one by one into the corresponding drying box 10. When it is necessary to stir, the motor 23 rotates, which drives the lead screw 22 to rotate, and then drives the sliding plate 24 to slide, moving the claw 9 to directly above the drying box 10 that needs to be stirred.
[0032] The electric push rod 3 extends its telescopic end, causing the piston plate 6 and the claw 9 to move downwards. The motor 7 rotates, causing the claw 9 to rotate and stir the material. The piston plate 6 moves downwards, causing the pressure inside the air chamber 4 to decrease. Outside air enters the air chamber 4 through the jet nozzle 8, pipe, and air hole 5.
[0033] After the mixing is complete, the motor 7 stops rotating, the claw 9 is located directly below the jet nozzle 8, the telescopic end of the electric push rod 3 shortens, driving the piston plate 6 and the claw 9 to move upward, the pressure inside the air chamber 4 increases, and the internal air is sprayed from the air hole 5, the pipe and the jet nozzle 8 onto the claw 9. As the claw 9 moves upward, the airflow blows from top to bottom onto the claw 9, causing the material and water droplets adhering to its outside to fall off, without affecting the subsequent mixing of materials.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
