Technical Field
[0001] This utility model relates to the field of stirring technology, and more specifically, to an electric stirring device. Background Technology
[0002] In the production of bio-fermentation products, it is often necessary to prepare various solutions such as culture media and buffer solutions in the laboratory. These operations all require electric stirrers for mixing.
[0003] In traditional electric mixers, the stirring rod is usually fixed on the stirring shaft. Its stirring range is mainly determined by the length and shape of the stirring rod. The stirring rod can only stir the material within a fixed radius. When the radius of the container is large, the length of the stirring rod causes areas that the electric mixer cannot reach, thus affecting the uniformity of the mixing. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric stirring device. The technical problem to be solved by the present invention is that the stirring range of the traditional electric stirrer is mainly determined by the length and shape of the stirring rod. When the radius of the container is large, there are areas that the electric stirrer cannot stir, which affects the uniformity of mixing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An electric stirring device includes a base, a stirring cylinder is mounted on the top surface of the base, an electric telescopic rod is fixedly installed on the top surface of the base, a mounting plate is fixedly installed on the top end of the electric telescopic rod, a motor is fixedly installed on the top surface of the mounting plate, the output shaft of the motor passes through the mounting plate and is connected to a stirring shaft, a mounting ring is fixedly installed on the outer side of the stirring shaft, a plurality of stirring rods are rotatably connected to the outer side of the mounting ring, a threaded sleeve is slidably connected to the bottom end of the stirring shaft, the stirring shaft drives the threaded sleeve to slide through a drive mechanism, a plurality of connecting rods are rotatably connected to the outer side of the threaded sleeve, and each connecting rod is rotatably connected to a stirring rod in a corresponding position.
[0007] like Figure 1-4 As shown, the specific implementation method is as follows: by setting a motor, a stirring shaft, and a stirring rod, the stirring shaft and stirring rod can be rotated by starting the motor, thereby achieving a stirring effect. By setting a connecting rod, a threaded sleeve, and a drive mechanism, the connecting rod can be rotated by sliding the threaded sleeve, thereby pushing the stirring rod to rotate, thereby increasing the stirring radius of the stirring rod in the stirring drum, thereby increasing the stirring effect, and thus adapting to stirring drums of different radii.
[0008] In a preferred embodiment, the drive mechanism includes a threaded rod, which is rotatably connected to the bottom end of the stirring shaft and threadedly connected to a threaded sleeve. A knob is fixedly installed at the end of the threaded rod away from the stirring shaft, and the mounting ring restricts the rotation of the threaded rod through a limiting mechanism.
[0009] In a preferred embodiment, the limiting mechanism includes a pin, which is elastically connected to the top surface of the mounting ring. A compression spring is fixedly connected to the top surface of the mounting ring, and the other end of the compression spring is fixedly connected to the top end of the pin. A limiting ring is fixedly installed on the outer side of the threaded rod. The limiting ring has multiple through holes, and the pin passes through the compression spring and is engaged in the corresponding through holes.
[0010] In a preferred embodiment, a plurality of spring telescopic rods are fixedly installed on the bottom surface of the mounting plate, and a cover plate is installed on the bottom end of the plurality of spring telescopic rods.
[0011] In a preferred embodiment, a limiting groove is formed on the top surface of the base, and multiple limiting plates are fixedly installed on the outer side of the stirring cylinder, with each limiting plate being formed in a corresponding limiting groove.
[0012] In a preferred embodiment, the radius of the cover plate is greater than the radius of the mixing drum.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting up a knob, threaded rod, threaded sleeve, connecting rod, stirring rod and other devices, realizes that turning the knob drives the threaded rod to rotate, thereby causing the threaded sleeve to slide upward and pushing the stirring rod outward through the rotation of the connecting rod, thereby increasing the stirring range of the stirring rod. Correspondingly, the knob can be turned in the opposite direction to make the threaded sleeve slide downward, thereby reducing the stirring range of the stirring rod.
[0015] 2. This utility model achieves the purpose of setting up a spring telescopic rod, a cover plate and other devices, so that the cover plate can be pressed against the top surface of the stirring cylinder by the spring telescopic rod, thereby avoiding solution splashing during stirring. At the same time, the radius of the cover plate is greater than the radius of the stirring cylinder, so as to be able to adapt to stirring cylinders with different radius lengths.
[0016] In summary, this invention is simple to operate and allows for flexible adjustment of the stirring range of the stirring rod according to the stirring drum of different radii, reducing dead zones and achieving uniform mixing. Attached Figure Description

Detailed Implementation
[0022] 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.
[0023] Reference Figure 1-4 An electric stirring device includes a base 1, a stirring cylinder 8 is mounted on the top surface of the base 1, an electric telescopic rod 2 is fixedly installed on the top surface of the base 1, an mounting plate 3 is fixedly installed on the top end of the electric telescopic rod 2, a motor 4 is fixedly installed on the top surface of the mounting plate 3, the output shaft of the motor 4 passes through the mounting plate 3 and is connected to a stirring shaft 7, an mounting ring 11 is fixedly installed on the outer side of the stirring shaft 7, a plurality of stirring rods 16 are rotatably connected to the outer side of the mounting ring 11, a threaded sleeve 14 is slidably connected to the bottom end of the stirring shaft 7, the stirring shaft 7 drives the threaded sleeve 14 to slide through a drive mechanism, a plurality of connecting rods 15 are rotatably connected to the outer side of the threaded sleeve 14, and each connecting rod 15 is rotatably connected to a stirring rod 16 corresponding to its position.
[0024] like Figure 1-4 As shown, the specific implementation method is as follows: by setting up a motor 4, a stirring shaft 7, and a stirring rod 16, the stirring shaft 7 and the stirring rod 16 can be rotated by starting the motor 4, thereby achieving a stirring effect. By setting up a connecting rod 15, a threaded sleeve 14, and a drive mechanism, the connecting rod 15 can be rotated by sliding the threaded sleeve 14, thereby pushing the stirring rod 16 to rotate, thereby increasing the stirring radius of the stirring rod 16 in the stirring drum 8, thereby increasing the stirring effect and adapting to stirring drums 8 with different radii.
[0025] The drive mechanism includes a threaded rod 12, which is rotatably connected to the bottom end of the stirring shaft 7. The threaded rod 12 is threadedly connected to the threaded sleeve 14. A knob 13 is fixedly installed at the end of the threaded rod 12 away from the stirring shaft 7. The mounting ring 11 restricts the rotation of the threaded rod 12 through a limiting mechanism. It is worth noting that multiple connecting rods 15 are rotatably connected to the stirring rod 16, which also restricts the threaded sleeve 14 from rotating. As a result, the threaded sleeve 14 can only slide linearly.
[0026] The limiting mechanism includes a pin 19, which is elastically connected to the top surface of the mounting ring 11. A compression spring 20 is fixedly connected to the top surface of the mounting ring 11, and the other end of the compression spring 20 is fixedly connected to the top end of the pin 19. A limiting ring 17 is fixedly installed on the outer side of the threaded rod 12. The limiting ring 17 has multiple through holes 18, and the pin 19 passes through the compression spring 20 and is locked in the corresponding through hole 18. The compression spring 20 can make the pin 19 firmly locked in the through hole 18, thereby limiting the rotation of the threaded rod 12 and preventing the stirring rod 16 from rotating during the stirring process.
[0027] Multiple spring telescopic rods 5 are fixedly installed on the bottom surface of the mounting plate 3. The bottom ends of the multiple spring telescopic rods 5 are all fitted with a cover plate 6. The cover plate 6 is pressed against the top surface of the stirring cylinder 8 by the spring telescopic rods 5, thereby preventing the solution from splashing during stirring.
[0028] A limiting groove 10 is provided on the top surface of the base 1, and multiple limiting plates 9 are fixedly installed on the outside of the mixing cylinder 8. Each limiting plate 9 is provided in the corresponding limiting groove 10. The multiple limiting grooves 10 can prevent the mixing cylinder 8 from rotating.
[0029] The radius of the cover plate 6 is greater than that of the stirring drum 8, so that it can accommodate stirring drums 8 of different diameters.
[0030] In use, this utility model is first released from the limiting ring 17 by pulling the pin 19 outward. Then, the knob 13 is turned to rotate the threaded rod 12. Due to the arrangement of multiple connecting rods 15 and stirring rod 16, the threaded sleeve 14 cannot rotate. The rotation of the threaded rod 12 can drive the threaded sleeve 14 to slide upward, and the rotation of the connecting rod 15 can push the stirring rod 16 outward, thereby increasing the stirring range of the stirring rod 16. When the inner diameter of the stirring cylinder 8 is adjusted to fit the inner diameter, the knob 13 is stopped and the pin 19 is released. Under the action of the compression spring 20, the pin 19 is inserted into the through hole 18 to limit the threaded rod 12. Then, the solution to be stirred is placed in the stirring cylinder 8. Then, the stirring cylinder 8 is locked in the limiting groove 10 by multiple limiting plates 9 to limit the stirring cylinder 8.
[0031] Then, by starting the electric telescopic rod 2, the mounting plate 3 is moved downward, and under the action of the spring telescopic rod 5, the cover plate 6 is pressed against the stirring cylinder 8 to prevent the solution from splashing during stirring. Then, the spring telescopic rod 5 is started to rotate the stirring shaft 7, so that the solution in the stirring cylinder 8 is stirred and mixed by the stirring rod 16.
[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
