[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5The utility model provides an embodiment: a bottom-entry stirring device, including a tank body 1 and a mounting plate 2. A mounting hole 6 is provided at the bottom of the tank body 1. The stirring structure enters the tank body 1 through the mounting hole 6. The mounting plate 2 is located below the tank body 1. A motor 3 is fixedly connected to the bottom of the mounting plate 2. The output end of the top of the motor 3 passes through the mounting plate 2 and is fixedly connected to a stirring rod 5. When the motor 3 is working, the stirring rod 5 can be driven to rotate, thereby achieving a stirring operation on the material. A sleeve 4 is fixedly connected to the top of the mounting plate 2. The stirring rod 5 is located in the middle of the sleeve 4. The sleeve 4 is matched with the stirring rod 5 to prevent the material from leaking from the mounting hole 6 without affecting the normal rotation of the stirring rod 5. A stirring assembly is rotatably connected to the outside of the stirring rod 5. The stirring assembly is driven to rotate by the rotation of the stirring rod 5 to achieve stirring of the material. The stirring assembly includes a connecting rod 9, which is rotatably connected to the outside of the stirring rod 5. The other end of the connecting rod 9 is rotatably connected to a stirring blade 10. The connecting rod 9 and the stirring blade 10 together form a parallelogram, so that the connecting rod 9 and the stirring blade 10 can rotate with each other and be folded and stowed. During assembly, the installation of the stirring mechanism can be completed by passing the stowed connecting rod 9 and the stirring blade 10 through the middle of the mounting hole 6. During the rotation of the stirring rod 5, the connecting rod 9 and the stirring blade 10 can be naturally unfolded under the action of centrifugal force. A top block 11 is fixedly connected to the outside of the stirring rod 5. The connecting rod 9 is located at the top of the top block 11 and contacts the top block 11. When the connecting rod 9 and the stirring blade 10 are unfolded, the bottom connecting rod 9 will contact the top of the top block 11, and the connecting rod 9 is supported by the top block 11, so that the rotation angle of the connecting rod 9 can be limited to ensure normal stirring.

[0032] Reference Figure 2 and Figure 3 A sealing member 8 is fixedly connected to the top of the sleeve 4, and the sealing member 8 can pass through the middle of the mounting hole 6 and extend inside the tank body 1. A sealing plate 7 is slidably connected to the outer periphery of the sleeve 4, and a locking structure is fixedly connected to the bottom of the sealing plate 7. After the sealing member 8 enters the tank body 1, the sealing plate 7 is lifted upward by the locking structure to reduce the distance between the sealing plate 7 and the sealing member 8, thereby blocking the position of the mounting hole 6 at the bottom of the tank body 1 to prevent material from leaking from the mounting hole 6. The locking structure includes a bolt 20, which is fixedly connected to the bottom of the sealing plate 7. Two nuts 21 are threadedly connected to the outer periphery of the bolt 20, and the two nuts 21 are respectively located on the upper and lower sides of the mounting plate 2; after the sealing member 8 enters the interior of the tank body 1, the nut 21 located between the mounting plate 2 and the sealing plate 7 is screwed to push the sealing plate 7 toward the sealing member 8. After the sealing plate 7 and the bottom of the tank body 1 are fully in contact, the mounting hole 6 is sealed, and then the nut 21 located under the mounting plate 2 is screwed to complete the fixation of the position of the mounting plate 2 to ensure the stability of the seal.

[0033] Reference Figure 3-Figure 4 , the outer side of the stirring rod 5 is fixedly connected with a fixed block 15, the outer side of the fixed block 15 is fixedly connected with a pressure rod 16, the top of the pressure rod 16 is rotatably connected with a support rod 17, the outer side of the stirring rod 5 is fixedly connected with a limit rod 12, the middle part of the limit rod 12 is slidably connected with a slider 14, the other end of the support rod 17 is rotatably connected to the outer side of the slider 14, and a spring 13 is sleeved on the outer periphery of the limit rod 12; during installation, the pressure rod 16 needs to be rotated along the fixed block 15 to fold and retract the pressure rod 16 together, and then after the pressure rod 16 enters the interior of the tank body 1, the slider 14 can be moved under the action of the spring 13, and the pressure rod 16 can be expanded outward under the action of the support rod 17, and because the pressure rod 16 is connected to the stirring rod 5, when the stirring rod 5 rotates, it can rotate together. One end of the spring 13 is fixedly connected to the top of the limit rod 12, and the other end of the spring 13 is fixedly connected to the top of the slider 14, and the slider 14 is acted on by the spring 13, so that the pressure rod 16 always remains in an expanded state. A scraper 18 is fixedly connected to the bottom of the pressure rod 16, and the bottom of the scraper 18 contacts the bottom of the tank body 1. Under the action of the spring 13, the scraper 18 can fully contact the bottom of the tank body 1, and then the bottom of the tank body 1 can be cleaned. A spring 19 is fixedly connected to the bottom of the pressure rod 16, and the other end of the spring 19 is located at the top of the scraper 18 near the seal 8. A section of the scraper 18 near the seal 8 exceeds the pressure rod 16, and then under the action of the spring 19, this part of the scraper 18 can contact the outer surface of the seal 8. When the stirring rod 5 rotates, the top of the seal 8 can be cleaned, thereby avoiding material accumulation and adhesion, thereby improving the quality of the material.

[0034] Working principle: During installation, the connecting rod 9 is rotated upward. Under the action of the parallelogram structure, the stirring blade 10 can be moved closer to the stirring rod 5, thereby reducing the top size of the stirring structure. Then, the folded stirring blade 10 and the connecting rod 9 are inserted from the mounting hole 6. After entering the tank body 1, the stirring blade 10 and the connecting rod 9 can be naturally unfolded and tend to be horizontal under the action of the top block 11. Then, the stirring rod 5 is pushed upward. After the seal 8 is deformed and contracted and enters the tank body 1, the distance between the mounting disk 2 and the sealing plate 7 is changed by screwing the nut 21, so that the sealing plate 7 slides upward and contacts the outer bottom of the tank body 1. At this time, the mounting hole 6 can be sealed under the action of the seal 8 and the sealing plate 7 to avoid material leakage during operation.

[0035] Secondly, after the stirring rod 5 enters the tank body 1, the spring 13 will act on the slider 14, so that the slider 14 slides outside the limit rod 12 and acts on the support rod 17, so that the pressure rod 16 can rotate along the fixed block 15. At this time, the pressure rod 16 can push the scraper 18 to contact the bottom of the tank body 1. When the stirring rod 5 rotates, the scraper 18 can be driven to rotate to clean the bottom of the tank body 1 to avoid the accumulation of materials at the bottom of the tank body 1. At the same time, the scraper 18 is pushed on the side close to the seal 8 by the spring piece 19, so that the end of the scraper 18 can contact the seal 8. When the stirring rod 5 rotates, the seal 8 can be cleaned synchronously, thereby avoiding the material from sticking and agglomerating on the upper part of the seal 8 during the stirring process, thereby ensuring the quality of the mixed material.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
