DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] In order to accurately control the discharging ratio of multiple materials and thus realize efficient and uniform mixing, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the adjustable proportional mixing device described in the present invention includes a base 1, a mixing frame 2 is provided above the base 1, and several groups of horizontally arranged feeding pipes 3 are distributed on the outer circumference of the mixing frame 2. The feeding pipes 3 are connected to the storage hopper 4, and a stirring motor 5 is installed on the top of the mixing frame 2. A stirring shaft 6 connected to the stirring motor 5 is provided in the mixing frame 2, and a spiral feeding rod 7 is provided in the feeding pipe 3. An electric telescopic rod 8 is installed at the end of the feeding pipe 3 away from the stirring motor 5, and the output end of the electric telescopic rod 8 is rotatably connected to the spiral feeding rod 7, and the spiral feeding rod 7 is driven by the stirring shaft 6 through a mobile speed change structure.

[0019] When in use, a variety of materials to be mixed are placed in the corresponding storage hoppers 4, and the materials will naturally fall into the feeding pipe 3 connected below, completing the material preparation before mixing; When it is necessary to discharge and mix the materials, the electric telescopic rod 8 is started, and the output end of the electric telescopic rod 8 drives the spiral feeding rod 7 to move horizontally along the feeding pipe 3. During the movement of the spiral feeding rod 7, a transmission relationship is established with the stirring shaft 6 by moving the speed change structure, so that the power of the stirring shaft 6 can be transmitted to the spiral feeding rod 7, driving the spiral feeding rod 7 to rotate. When the spiral feeding rod 7 rotates, the material in the feeding pipe 3 is continuously pushed into the mixing frame 2; at the same time, the stirring motor 5 on the top of the mixing frame 2 is started, driving the stirring shaft 6 to rotate, stirring and mixing the materials entering the mixing frame 2, and achieving preliminary mixing of the materials; When it is necessary to increase the feeding amount of a single group of materials, the electric telescopic rod 8 is further driven to shorten, driving the screw feeding rod 7 to move away from the stirring shaft 6. At this time, the moving speed change structure will change the transmission ratio between the screw feeding rod 7 and the stirring shaft 6, so that the rotation speed of the screw feeding rod 7 is increased, thereby increasing the material conveying amount of the feeding tube 3 of this group; on the contrary, if the electric telescopic rod 8 is extended, the screw feeding rod 7 moves towards the stirring shaft 6, the rotation speed of the screw feeding rod 7 is reduced, and the feeding amount is reduced; For several groups of feeding pipes 3 distributed on the circumference, the rotation speed of each group of spiral feeding rods 7 can be changed by adjusting the extension amount of the electric telescopic rod 8 corresponding to each group respectively, so as to accurately control the feeding ratio of each group of materials. For example, when materials A and B need to be mixed in a ratio of 1:2, the rotation speed of the spiral feeding rod 7 of group B can be made twice that of group A by adjusting the electric telescopic rods 8 corresponding to A and B, thereby ensuring that the two materials enter the mixing frame 2 according to the preset ratio. The final mixed material ratio is stable and consistent. There is no need to manually operate the valve. The spiral feeding rod 7 is driven by the electric telescopic rod 8, and the mechanical automatic adjustment of the feeding amount is realized by cooperating with the mobile speed change structure, thereby improving the adjustment accuracy. For multiple materials, the feeding speed of each group of materials can be accurately controlled by independently adjusting the electric telescopic rod 8 of each group of feeding pipes 3, thereby ensuring that the materials always enter the mixing frame 2 according to the preset equal proportion, avoiding the imbalance of multiple material proportions, and meeting the strict requirements of the production process on the material mixing ratio.

[0020] In order to facilitate the adjustment of the feeding amount of the material, for example, Figure 3 、 Figure 4 、 Figure 5 As shown, the present invention also includes that a first discharge port 9 is provided below one end of the feeding tube 3 located in the mixing frame 2, and an arc-shaped baffle 10 is provided below the first discharge port 9. A second discharge port 11 is provided on the arc-shaped baffle 10, and the second discharge port 11 is initially staggered with the first discharge port 9. The end of the spiral feeding rod 7 away from the electric telescopic rod 8 is connected to the rotating rod 12, and a sliding hole corresponding to the rotating rod 12 is provided on the feeding tube 3. The rotating rod 12 passes through the sliding hole and is rotatably connected to the rotating ring 13, and the rotating ring 13 is connected to the arc-shaped baffle 10 through the bracket 14.

[0021] During use, when it is necessary to convey materials, first, the electric telescopic rod 8 is started, and the output end of the electric telescopic rod 8 will drive the spiral feeding rod 7 to move horizontally along the feeding pipe 3. When the spiral feeding rod 7 moves, it will drive the rotating rod 12 to move synchronously along the slide hole. When the rotating rod 12 moves, the arc baffle 10 is driven to move synchronously by the rotating ring 13 and the bracket 14. In the initial state, the first discharge port 9 and the second discharge port 11 are in a staggered state. At this time, the material cannot enter the mixing frame 2 through the discharge port. As the arc baffle 10 moves, the second discharge port 11 will gradually overlap with the first discharge port 9. When the two discharge ports begin to overlap, the material in the feeding pipe 3 can enter the mixing frame 2 through the first discharge port 9 and the second discharge port 11; If you want to further increase the feeding amount, you can adjust the electric telescopic rod 8 to make the spiral feeding rod 7 continue to move, thereby driving the rotating rod 12, the rotating ring 13 and the bracket 14 to push the arc baffle 10 to move, thereby increasing the overlapping area of ​​the first discharge port 9 and the second discharge port 11. At the same time, relying on the mobile speed change structure, the rotation speed of the rotating rod 12 and the spiral feeding rod 7 is synchronously increased during the movement of the spiral feeding rod 7, so that the material passing rate of the discharge port is increased, and the speed of the spiral feeding rod 7 to transport the material is accelerated, thereby significantly improving the overall feeding amount.

[0022] In order to facilitate the rotation of the spiral feeding rod 7, for example, Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the present invention also includes that the mobile speed change structure includes a turntable 15 rotatably connected to the stirring shaft 6 and a friction wheel 16 connected to the end of the rotating rod 12, and the lower surface of the turntable 15 is detachably connected to the annular friction disk 17. The turntable 15 is connected to the stirring shaft 6 through an elastic member, and the friction wheel 16 is initially located in the middle of the turntable 15.

[0023] During use, a variety of materials to be mixed are poured into the storage hopper 4 above the corresponding feeding pipe 3 respectively. The materials naturally fall into the feeding pipe 3 under the action of gravity, and the electric telescopic rod 8 corresponding to the feeding pipe 3 is started. The output end of the electric telescopic rod 8 is shortened, driving the spiral feeding rod 7 to move horizontally in the direction away from the mixing frame 2. When the spiral feeding rod 7 moves, it drives the arc baffle 10 to move synchronously, so that the second discharge port 11 gradually overlaps with the first discharge port 9 of the feeding pipe 3. At the same time, the friction wheel 16 at the end of the rotating rod 12 moves with the rotating rod 12, gradually approaches the annular friction disk 17 on the lower surface of the turntable 15, and finally contacts the annular friction disk 17; Start the stirring motor 5 on the top of the mixing frame 2, the stirring shaft 6 rotates and drives the turntable 15 to rotate synchronously through the elastic member. Because the friction wheel 16 is in contact with the annular friction disk 17, when the turntable 15 rotates, the annular friction disk 17 drives the friction wheel 16 to rotate through friction force, and the rotation of the friction wheel 16 drives the rotating rod 12 to rotate. The rotating rod 12 is fixedly connected to the spiral feeding rod 7, so the spiral feeding rod 7 rotates synchronously. When the spiral feeding rod 7 rotates, the material in the feeding pipe 3 is pushed toward the first discharge port 9 and the second discharge port 11, completing the initial feeding; If it is necessary to increase the feeding amount of the material, the electric telescopic rod 8 is further controlled to be shortened, and the rotating rod 12 pushes the arc baffle 10 to continue to move, and the overlapping area of ​​the first discharge port 9 and the second discharge port 11 is increased, thereby increasing the feeding amount; at the same time, the rotating rod 12 drives the friction wheel 16 to move radially toward the edge along the annular friction disk 17, so that the friction wheel 16 gradually moves away from the center of the turntable 15, and the distance from the contact point between the friction wheel 16 and the annular friction disk 17 to the center of the turntable 15, that is, the contact radius gradually increases. At this time, the annular friction disk 17 drives the friction wheel 16 to rotate faster through the friction force, and then transmits it to the spiral feeding rod 7 through the rotating rod 12, so that the rotation speed of the spiral feeding rod 7 is increased, and the material conveying speed is accelerated. The two act synchronously, allowing more materials to pass through the discharge port and allowing the materials to be conveyed to the discharge port faster, greatly improving the adjustment efficiency and amplitude of the feeding amount, and ensuring that the feeding amount can be increased quickly and stably as needed; On the contrary, if the electric telescopic rod 8 pulls the friction wheel 16 to move toward the center of the annular friction disk 17, the radius of the contact point decreases, and the rotation speed of the friction wheel 16 and the spiral feeding rod 7 also decreases, and the material conveying speed slows down. At the same time, the reduction in the overlapping area of ​​the discharge port is combined with the reduction in the rotation speed of the spiral feeding rod 7, which not only limits the material throughput, but also slows down the pushing speed, avoids excessive feeding, and realizes precise reduction of the feeding amount. It can accurately match the material mixing ratio requirements in different scenarios, and reduce the problem of unstable feeding caused by single adjustment, only adjusting the speed or only adjusting the channel.

[0024] In order to enhance the stirring effect and make the materials mixed more evenly, for example, Figure 4 、 Figure 8 、 Figure 9 The present invention further includes that several groups of first stirring rods 18 are arranged above the stirring shaft 6, and a through groove 19 is provided in the first stirring rod 18. A sealing plate 20 is sealed and slidably connected in the through groove 19, and a second stirring rod 21 is fixedly connected to one side of the sealing plate 20. A return spring 22 is fixedly connected between the side of the sealing plate 20 away from the second stirring rod 21 and the inner wall of the through groove 19, and a liquid inlet channel 23 connected to the through groove 19 is provided in the stirring shaft 6, and the elastic member is connected to the liquid inlet channel 23.

[0025] During use, when the stirring shaft 6 rotates, it exerts an extrusion effect on the elastic member. Since the elastic member is connected to the liquid inlet channel 23, under the action of the extrusion, the liquid in the liquid inlet channel 23 is transported to the through groove 19 of the first stirring rod 18. The liquid entering the through groove 19 exerts pressure on the sealing plate 20, pushing the sealing plate 20 to slide in the through groove 19. When the sealing plate 20 moves, it drives the second stirring rod 21 to move synchronously, so that the second stirring rod 21 extends from the through groove 19 of the first stirring rod 18, thereby expanding the stirring range and more fully contacting with the material in the mixing frame 2, thereby enhancing the stirring effect and making the materials mixed more evenly. When the stirring shaft 6 stops rotating, the squeezing effect on the elastic member disappears, and the reset spring 22 pushes the sealing plate 20 to move in the opposite direction for reset. When the sealing plate 20 resets and moves, it drives the second stirring rod 21 to move together, so that the second stirring rod 21 is retracted into the through groove 19 of the first stirring rod 18, reducing the space occupied by the stirring rod in the non-working state, and also facilitating the cleaning or maintenance of the interior of the device; at the same time, during the retraction process of the second stirring rod 21, the outer wall of the second stirring rod 21 will contact and slide relative to the inner wall of the through groove 19, so that the residual material on the outer wall of the second stirring rod 21 can be scraped off.

[0026] In order to dynamically adjust the stirring effect according to the feeding amount and feeding speed and improve the uniformity of material mixing, the present invention also includes, illustratively, that the elastic coefficient of the return spring 22 increases step by step from bottom to top.

[0027] During use, when the feeding amount and feeding speed of the feeding pipe 3 increase, the material in the mixing frame 2 gradually increases, and the squeezing force on the elastic member when the stirring shaft 6 rotates will gradually increase. At this time, the liquid in the elastic member is squeezed and enters the through groove 19 of the first stirring rod 18 through the liquid inlet channel 23. The sealing plate 20 in the through groove 19 moves in the direction away from the return spring 22 under the action of the liquid pressure, thereby driving the second stirring rod 21 to extend from the through groove 19 of the first stirring rod 18. Since the elastic coefficient of the return spring 22 increases step by step from bottom to top, the elastic coefficient of the lower return spring 22 is smaller, so that the lower second stirring rod 21 extends first; as the material continues to increase, the squeezing force of the stirring shaft 6 on the elastic member further increases, and the liquid pressure also increases accordingly. After overcoming the elastic force of the upper return spring 22 with a larger elastic coefficient, the upper second stirring rod 21 is extended in turn; Among them, when the feeding amount and feeding speed gradually increase, resulting in the gradual increase of material in the mixing frame 2, the second stirring rod 21 can be gradually extended from bottom to top, so that the second stirring rod 21 that extends first at the bottom can first stir the gradually increasing material at the bottom. As the material stacking height rises, the second stirring rod 21 above will participate in the stirring in turn, expanding the stirring range at different heights, ensuring that materials at different heights in the mixing frame 2 can be fully stirred, thereby dynamically adjusting the stirring effect according to the feeding amount and feeding speed, and improving the uniformity of material mixing.

[0028] In order to achieve the goal of gradually expanding the stirring range from bottom to top as the amount of material increases, ensuring that materials at different heights can be fully stirred, for example, Figure 6 、 Figure 7 、 Figure 8As shown, the present invention also includes that the elastic member includes an arc-shaped telescopic rod 24 horizontally arranged on the upper surface of the turntable 15, the fixed end of the arc-shaped telescopic rod 24 is fixedly connected to the upper surface of the turntable 15 through a fixed plate 26, the output end of the arc-shaped telescopic rod 24 is fixedly connected to the stirring shaft 6 through a connecting rod 25, the fixed end of the arc-shaped telescopic rod 24 is filled with liquid, and one side of the fixed plate 26 is provided with a liquid outlet joint 27 connected to the arc-shaped telescopic rod 24, and the liquid outlet joint 27 is connected to the liquid inlet channel 23 through a pipeline.

[0029] When in use, the friction wheel 16 is initially located in the middle of the rotary disc 15 and is in initial contact or non-contact with the annular friction disc 17. The arc-shaped telescopic rod 24 is in a naturally telescopic state, and the internal liquid pressure is stable. When the stirring shaft 6 rotates, the arc-shaped telescopic rod 24, the fixed plate 26 and the turntable 15 are driven to rotate synchronously by the connecting rod 25. When the electric telescopic rod 8 adjusts the movement of the spiral feeding rod 7 and drives the friction wheel 16 at the end of the rotating rod 12 to move toward the annular friction disk 17, the friction wheel 16 and the annular friction disk 17 are frictionally transmitted. At this time, when the stirring shaft 6 rotates, it will drive the connecting rod 25 to squeeze the output end of the arc-shaped telescopic rod 24, so that the liquid in the fixed end of the arc-shaped telescopic rod 24 is supplied to the liquid inlet channel 23 through the liquid outlet connector 27 on the fixed plate 26, and drive the second stirring rod 21 at the bottom of the stirring shaft 6 to extend, thereby ensuring the stirring effect; When the electric telescopic rod 8 drives the friction wheel 16 at the end of the rotating rod 12 to move toward the edge of the friction wheel 16, the radius of the contact point between the friction wheel 16 and the annular friction disc 17 increases. Since the friction wheel 16 needs to be driven synchronously with the turntable 15, the resistance of the friction wheel 16 to the annular friction disc 17 increases. At this time, when the stirring shaft 6 rotates, it will further drive the connecting rod 25 to squeeze the output end of the arc-shaped telescopic rod 24, causing the arc-shaped telescopic rod 24 on the upper surface of the turntable 15 to be further squeezed. After being squeezed, the liquid in the fixed end of the arc-shaped telescopic rod 24 enters the liquid inlet channel 23 of the stirring shaft 6 through the liquid outlet joint 27 and the pipeline, and flows into the through groove 19 of each first stirring rod 18 along the liquid inlet channel 23. The liquid pressure in the through groove 19 pushes the sealing plate 20 to overcome the elastic force of the return spring 22 and move, driving the second stirring rod 21 to extend from the through groove 19 of the first stirring rod 18, thereby expanding the stirring range; When the feeding amount increases, the friction wheel 16 is at the edge of the annular friction disc 17, and the stirring range is automatically expanded. When the feeding amount decreases, the friction wheel 16 is in the middle of the annular friction disc 17, and the stirring range is automatically reduced. No additional power is required to control the extension and retraction of the stirring rod, thus achieving dynamic matching of feeding and stirring, reducing energy consumption and improving the coordination of the device. When the friction wheel 16 moves toward the edge, the speed of the spiral feeding rod 7 increases, the feeding amount increases, and the material in the mixing frame 2 increases. At this time, the liquid pressure generated by the extrusion of the arc-shaped telescopic rod 24 is transmitted to the stirring shaft 6 through the liquid inlet channel 23, pushing the second stirring rod 21 to extend, so that the second stirring rod 21 below the stirring shaft 6 extends first due to the smaller spring force, and preferentially stirs the material increasing at the bottom; as the material accumulation height increases, the second stirring rod 21 above extends in turn, so that the stirring range gradually expands from bottom to top as the material amount increases, ensuring that materials at different heights can be fully stirred; When the device stops working, the return spring 22 drives the second stirring rod 21 to retract into the through groove 19, and the liquid in the liquid inlet channel 23 is squeezed and transported to the fixed end of the arc-shaped telescopic rod 24, so that the arc-shaped telescopic rod 24 is reset, facilitating the subsequent stirring operation of the next group of materials.

[0030] For example, Figure 6 、 Figure 7 As shown, the present invention also includes that a positioning hole 28 is provided on the rotating ring 13, and a positioning rod 29 corresponding to the positioning hole 28 is provided at one end of the feeding tube 3, and the positioning rod 29 passes through the positioning hole 28 and is slidably connected to the positioning hole 28.

[0031] During use, the positioning rod 29 and the positioning hole 28 can ensure the overall stability of the rotating ring 13, avoid deflection or skew during movement, and ensure that the first discharge port 9 and the second discharge port 11 always maintain a parallel alignment state.

[0032] For example, Figure 3 As shown, the present invention also includes that an electric discharge bin door 30 is provided at the bottom of the mixing frame 2.

[0033] During use, when the material in the mixing frame 2 is fully mixed by the stirring shaft 6 and the first stirring rod 18 and the second stirring rod 21 and reaches the preset mixing uniformity, the electric discharge bin door 30 is started, and the mixed material is discharged through the electric discharge bin door 30 under the action of gravity.

[0034] For example, Figure 6 、 Figure 7 As shown, the present invention also includes that the upper surface of the turntable 15 is provided with a plurality of groups of circumferentially distributed heat sinks 31 .

[0035] During use, the friction wheel 16 and the annular friction disc 17 are in contact and driven, which will generate heat due to friction. At the same time, the turntable 15 will also generate a certain amount of heat when rotating with the stirring shaft 6. The heat sink 31 can increase the contact area between the turntable 15 and the air, thereby accelerating the heat dissipation rate.

[0036] When the present invention is used, different types of materials to be mixed are poured into the corresponding storage hopper 4 according to the mixing requirements. The materials fall naturally under the action of gravity and enter the feeding pipe 3 connected to the bottom of the storage hopper 4, completing the material preparation before mixing; Start the stirring motor 5 on the top of the mixing frame 2, and the stirring motor 5 drives the stirring shaft 6 connected thereto to start rotating. When the stirring shaft 6 rotates, the connecting rod 25, the arc-shaped telescopic rod 24, the fixed plate 26, and the turntable 15 are driven to rotate synchronously, providing a power basis for the subsequent transmission of the spiral feeding rod 7; Start the electric telescopic rod 8, and the output end of the electric telescopic rod 8 drives the spiral feeding rod 7 to move horizontally along the feeding pipe 3. When it is necessary to increase the feeding amount of a certain group of materials, the electric telescopic rod 8 is controlled to shorten, driving the spiral feeding rod 7 to move in the direction away from the stirring shaft 6. At this time, the friction wheel 16 at the end of the rotating rod 12 moves toward the edge of the annular friction disk 17. Since the contact radius of the friction wheel 16 and the annular friction disk 17 increases, the rotation speed of the spiral feeding rod 7 increases; at the same time, the rotating rod 12 drives the arc baffle 10 to move through the rotating ring 13 and the bracket 14, so that the overlapping area of ​​the first discharge port 9 and the second discharge port 11 is increased, the material passing rate is improved, and the feeding amount is increased under the dual action; When the feeding amount of a certain group of materials needs to be reduced, the electric telescopic rod 8 is controlled to extend, driving the screw feeding rod 7 to move closer to the stirring shaft 6, and the friction wheel 16 moves to the middle of the annular friction disk 17, the contact point radius is reduced, and the speed of the screw feeding rod 7 is reduced; at the same time, the arc baffle 10 moves to reduce the overlapping area of ​​the two discharge ports, the material passing rate is reduced, and the feeding amount is reduced; As the spiral feeding rod 7 rotates, it pushes the material in the feeding pipe 3 toward the mixing frame 2. The material passes through the overlapping area of ​​the first discharge port 9 and the second discharge port 11 and enters the mixing frame 2. Multiple groups of feeding pipes 3 convey the material synchronously according to the set ratio, and the material is initially gathered in the mixing frame 2. When the stirring shaft 6 rotates, the arc-shaped telescopic rod 24, the fixed plate 26 and the turntable 15 are driven to rotate synchronously by the connecting rod 25. When the electric telescopic rod 8 adjusts the movement of the spiral feeding rod 7 and drives the friction wheel 16 at the end of the rotating rod 12 to move toward the annular friction disk 17, the friction wheel 16 and the annular friction disk 17 are frictionally transmitted. At this time, when the stirring shaft 6 rotates, it will drive the connecting rod 25 to squeeze the output end of the arc-shaped telescopic rod 24, so that the liquid in the fixed end of the arc-shaped telescopic rod 24 is supplied to the liquid inlet channel 23 through the liquid outlet connector 27 on the fixed plate 26, and drive the second stirring rod 21 at the bottom of the stirring shaft 6 to extend, thereby ensuring the stirring effect; When the electric telescopic rod 8 drives the friction wheel 16 at the end of the rotating rod 12 to move toward the edge of the friction wheel 16, the radius of the contact point between the friction wheel 16 and the annular friction disc 17 increases. Since the friction wheel 16 needs to be driven synchronously with the turntable 15, the resistance of the friction wheel 16 to the annular friction disc 17 increases. At this time, when the stirring shaft 6 rotates, it will further drive the connecting rod 25 to squeeze the output end of the arc-shaped telescopic rod 24, causing the arc-shaped telescopic rod 24 on the upper surface of the turntable 15 to be further squeezed. After the liquid in the fixed end of the arc-shaped telescopic rod 24 is squeezed, it enters the liquid inlet channel 23 of the stirring shaft 6 through the liquid outlet joint 27 and the pipeline, and flows along the inlet channel 23. The liquid channel 23 flows into the through groove 19 of each first stirring rod 18. The liquid pressure in the through groove 19 pushes the sealing plate 20 to overcome the elastic force of the return spring 22 and move, driving the second stirring rod 21 to extend from the through groove 19 of the first stirring rod 18, thereby expanding the stirring range. The stirring parameters are adaptively adjusted according to the actual discharge volume of the material. When the material discharge volume is large, fixed stirring parameters may lead to insufficient material mixing and poor uniformity, resulting in local material aggregation or stratification. When the material discharge volume is small, if the stirring intensity is not reduced accordingly, it may cause energy waste and even damage the characteristics of some sensitive materials due to excessive stirring. Adaptive adjustment can be made according to the actual material discharge volume to avoid fixed stirring parameters that may lead to insufficient material mixing, poor uniformity, local material aggregation or stratification when the material discharge volume is large; and when the material discharge volume is small, if the stirring intensity is not reduced accordingly, it will cause energy waste and even damage the characteristics of some sensitive materials due to excessive stirring; When the material is stirred in the mixing frame 2 for a preset time or meets the mixing requirements, the stirring motor 5 and the electric telescopic rod 8 are turned off, the feeding and stirring are stopped, and the electric discharge bin door 30 at the bottom of the mixing frame 2 is started. The mixed material is discharged through the electric discharge bin door 30 under the action of gravity, completing the entire mixing process; after the discharge is completed, the electric discharge bin door 30 is closed. At this time, the reset spring 22 pushes the sealing plate 20 to reset, driving the second stirring rod 21 to retract into the through groove 19 of the first stirring rod 18, and at the same time the arc-shaped telescopic rod 24 is reset, and the liquid flows back to the fixed end of the arc-shaped telescopic rod 24.
