Technical Field

[0001] This application relates to the field of mechanical technology, and in particular to a lifting and lowering stirring device. Background Technology

[0002] Small mixing devices are widely used in indoor and outdoor material mixing operations. Their structure mainly includes a mobile frame, a tilting frame mounted on the mobile frame, a mixing component connected to the tilting frame, and a mixing drum inside the tilting frame. The mixing rod in the mixing component extends into the mixing drum to mix the materials added therein.

[0003] Because the mixing tank has a certain depth, the mixing components cannot evenly mix the materials inside the tank, resulting in low mixing quality and low mixing efficiency. Summary of the Invention

[0005] A liftable stirring device includes a container for holding the material to be stirred, and further includes:

[0006] A stirring mechanism includes a drive assembly and a stirring blade connected to the drive assembly. Under the drive of the drive assembly, the stirring blade rotates about a first axis, which forms a golden angle with the geometric center line of the container.

[0007] A lifting mechanism, comprising a fixed component and a movable component, wherein the movable component is movable relative to the fixed component, the fixed component is connected to the container, and the movable component is connected to the drive assembly;

[0008] The movement trajectory of the movable component does not intersect with the geometric center line of the container or the first axis, and the movable component can drive the stirring blade to move synchronously within the container through the driving component.

[0009] In some embodiments, the fixed member and the movable member are slidably connected, and the lifting mechanism further includes an elastic member located between the fixed member and the movable member, the elastic member being used to assist the movement of the movable member.

[0014] In some embodiments, the movable member and the fixed member are provided with a support component at the end near the connection with the drive assembly. During the sliding of the movable member relative to the fixed member, the support component can reduce the sliding resistance of the movable member and provide support force to the movable member.

[0015] In some embodiments, the fixing member is a hollow structure, a fixing sleeve is fixed inside the fixing member, a central rod is provided inside the fixing sleeve, and the movable member is slidably connected to the central rod.

[0016] In some embodiments, a bushing fixedly connected to the movable member is also included, the bushing being slidably connected to the center rod.

[0017] In some embodiments, a tilting frame and an adjustable elastic structure are also included. The container is located above the tilting frame, and the bottom side of the container away from the fixing member is connected to the tilting frame via a hinged seat. The lower end of the fixing member is hinged to the tilting frame. The tilting frame is provided with an abutment rod, which is used to limit the swing of the fixing member away from the container.

The sliding plate and the half-cover are slidably connected in the direction close to or away from the fixed plate. A vertical rod is fixed to the sliding plate. The vertical rod passes through the movable plate. A connecting block is fixed to the vertical rod. The connecting block is rotatably connected to a vertically arranged bolt. One end of the bolt is threaded to the movable plate.

[0018] In summary, this application has at least one of the following beneficial technical effects:

[0019] 1.

[0041] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0042] Example 1, please refer to Figures 1-10 This paper discloses the structure of an embodiment of a liftable stirring device, including a container 1 for holding materials to be stirred, a stirring mechanism 2, a lifting mechanism 3, and a tilting frame 4. The container 1 is connected to the tilting frame 4, the lifting mechanism 3 is mounted on the tilting frame 4, and the stirring mechanism 2 is connected to the lifting mechanism 3 and partially located inside the container 1. Depending on the functional requirements of the product, the container 1 and the tilting frame 4 can be fixedly connected or rotatably connected. Rollers 5 are connected to the bottom of the tilting frame 4 to facilitate the movement of the stirring device. The stirring mechanism 2 includes a drive assembly and a stirring blade 23 connected to the drive assembly. Driven by the drive assembly, the stirring blade 23 rotates around a first axis, which forms a golden angle with the geometric center line of the container 1. The first axis is the rotation axis of the drive assembly. The lifting mechanism 3 includes a fixed part 31 and a movable part 32. The movable part 32 can move relative to the fixed part 31. The fixed part 31 is connected to the container 1, and the movable part 32 is connected to the drive assembly. The movement trajectory of the movable end does not intersect with the geometric center line of the container 1 or the first axis. The movable part 32 can drive the stirring blade 23 to move synchronously within the container 1 through the drive assembly.

[0043] Please see Figure 1 An anti-rotation structure 12 is also provided between the tilting frame 4 and the container 1. The anti-rotation structure 12 can prevent the container 1 from rotating relative to the tilting frame 4, thereby improving the stability of the stirring device.

[0044] Please see Figure 3 The stirring mechanism 2 includes a motor 21, a stirring shaft 22, and stirring blades 23. The stirring shaft 22 is fixedly connected to the output shaft of the motor 21, and the stirring blades 23 are connected to the end of the stirring shaft 22 away from the motor 21. Multiple stirring blades 23 are evenly distributed along the axis of the stirring shaft 22, which is the first axis. In this embodiment, the stirring blades 23 are fixedly connected to the stirring shaft 22. In practical applications, depending on functional requirements, the stirring blades 23 can be rotatably connected to the stirring shaft 22 on the plane of the stirring shaft 22's axis to achieve a folding and storage function. The stirring blades 23 extend into the container 1 through the stirring shaft 22, and the motor 21 is connected to the lifting mechanism 3.

[0045] The lifting mechanism 3 includes a fixed component 31 and a movable component 32. The fixed component 31 is fixedly connected to the tilting frame 4. In this embodiment, the movable component 32 is slidably connected to the fixed component 31. Depending on the actual functional requirements, the movable component 32 can be configured to move relative to the fixed component 31 along a spatial motion trajectory, so that the movable component 32, driven by the motor 21 and the stirring shaft 22, can drive the stirring blade 23 to achieve stirring processing at different positions and angles within the container 1. To achieve the three-dimensional spatial motion trajectory function, a three-dimensional track can be set on the fixed component 31, and the movable component 32 can slide along the three-dimensional track. In this embodiment, both the fixed component 31 and the movable component 32 are hollow square tubes. A fixed sleeve 34 is fixedly installed inside the fixed component 31. An elastic component 33 is connected between the fixed sleeve 34 and the movable component 32. In this embodiment, the elastic component 33 is a spring, which abuts against the movable component 32 to apply a spring force to the movable component 32 in a direction away from the fixed sleeve 34. A mounting bracket 321 is fixedly connected to the end of the movable part 32 away from the elastic part 33, and the mounting bracket 321 is fixedly connected to the motor 21.

[0046] Please see Figure 3 The golden angle is the angle between the axis of the stirring shaft 22 and the geometric center line of the container 1. This angle lies within the plane shared by the axis of the stirring shaft 22 and the geometric center line of the container 1. The end of the stirring shaft 22 closest to the motor 21 and near the movable part 32, and the end of the stirring shaft 22 connected to the stirring blade 23, is inclined away from the fixed part 31. The golden angle ranges from 1° to 5°, preferably 2°. This golden angle setting helps the operator, when manually operating the movable part 32, to apply force towards their body when the movable part 32 moves away from the fixed part 31, resulting in less resistance and better ergonomics.

[0047] Please see Figure 4In this embodiment, a central rod 36 is provided inside the fixing member 31, which can be either hollow or solid. A sliding member 35 is provided between the central rod 36 and the movable member 32 to reduce frictional resistance. During the sliding process of the movable member 32 relative to the fixing member 31, the sliding member 35 abuts against the central rod 36, and the movable member 32 is located between the sliding member 35 and the fixing member 31. In this embodiment, the sliding member 35 is a linear bearing, and there are two linear bearings, which are fixedly connected to the movable member 32. One end of the sliding member 35 and the movable member 32 is connected to a baffle 38, which abuts against a spring. Depending on actual needs, the sliding member 35 can also be other sliding or rolling connection components. To ensure stable sliding of the movable part 32 relative to the fixed part 31 during mixing, a bushing 37 is provided between the movable part 32 and the central rod 36. The inner wall of the bushing 37 is smooth and wear-resistant. The bushing 37 is fixedly connected to the movable part 32 and is either gap-connected or abuts against the central rod 36. During mixing, the movable part 32 is subjected to the reaction force of mixing. The bushing 37 can limit the swing range of the movable part 32 to ensure the reliability of the function.

[0048] Please see Figure 5 A handle 322 is fixedly connected to the end of the movable part 32. In this embodiment, there are two handles 322 symmetrically arranged on both sides of the movable part 32. The handles 322 can drive the movable part 32 to slide relative to the fixed part 31. A tightening screw 311 is threadedly connected to the fixed part 31. When the movable part 32 slides to the predetermined position, the fixed part 31 and the movable part 32 are connected and fixed by tightening the tightening screw 311 to keep the position of the movable part 32 stable.

[0049] Please see Figure 6 A limiting component is also provided between the fixed member 31 and the movable member 32. The limiting component includes a limiting member 6 provided on the fixed member 31 and a limiting groove 323 provided on the movable member 32. The movable member 32 is located in the limiting groove 323, which can limit the range of sliding of the movable member 32 relative to the fixed member 31.

[0050] Please see Figure 7 When the limiting member 6 abuts against the upper end of the limiting groove 323, the movable member 32 retracts into the fixed member 31, and the end of the movable member 32 closest to the mounting bracket 321 approaches the fixed bracket, resulting in the shortest distance between the farthest ends of the mounting bracket 321 and the fixed member 31. (Reference) Figure 3 The mounting bracket 321 is fixedly connected to the motor 21, so the motor 21 is also close to the container 1. The motor 21 drives the stirring blade 23 to approach the bottom of the container 1 through the stirring shaft 22. In this state, the bottom area of ​​the container 1 can be fully stirred.

[0051] Please see Figure 8When the limiting member 6 abuts against the lower end of the limiting groove 323, the end of the movable member 32 near the mounting bracket 321 moves away from the fixed member 31, and the distance between the farthest ends of the mounting bracket 321 and the fixed member 31 is the longest. (Reference) Figure 3 The mounting bracket 321 is fixedly connected to the motor 21, so the motor 21 is also away from the container 1. The motor 21 drives the stirring blade 23 away from the bottom of the container 1 through the stirring shaft 22. In this state, the upper area of ​​the container 1 can be fully stirred.

[0052] Please see Figure 3 , Figure 7 and Figure 8 When the limiting member 6 is located in the middle position of the limiting groove 323, the stirring blade 23 can fully stir the middle area of ​​the container 1. By setting the positional relationship between the limiting member 6 and the limiting groove 323, the stirring blade 23 can stir different unknown areas in the container 1, thereby improving the quality and efficiency of stirring.

[0053] Please see Figure 3 and Figure 5 By applying force to the handle 322 by the operator, the movable part 32 slides up and down relative to the fixed part 31, which allows the stirring blade 23 to stir up and down repeatedly in the container 1, so as to fully stir the entire area in the container 1, making the stirring more uniform and more efficient.

[0054] In a specific embodiment, the handle 322 can also be configured as a reciprocating motion mechanism driven by the motor 21, with the motor 21 driving a reciprocating screw to achieve the reciprocating sliding of the movable part 32 relative to the fixed part 31. Alternatively, the motor 21 can drive a linkage mechanism, belt mechanism, or gear mechanism to achieve reciprocating motion, thereby driving the movable part 32 to slide reciprocally relative to the fixed part 31.

[0055] Please see Figure 9 and Figure 10 A support assembly 7 is also provided between the fixed part 31 and the movable part 32, and the support assembly 7 is located at the end of the fixed frame near the mounting frame 321. During the stirring process, refer to Figure 3 The material exerts a downward reaction force on the stirring blade 23, causing the stirring blade 23, along with the stirring mechanism 2 and the mounting frame 321, to experience a leftward and downward pulling force (as shown in the diagram). The position of the rolling element provides support and, due to its rolling characteristics, does not affect the smoothness of lifting and lowering. The support assembly 7 includes an inner ring 73, an outer ring 71, and a fixed shaft 72. The fixed shaft 72 is fixedly connected to the fixed member 31, and the inner ring 73 is rotatably connected to the fixed member 31 via the fixed shaft 72. The inner ring 73 and the outer ring 71 are coaxially arranged and can slide relative to each other, equivalent to a sliding bearing or a rolling bearing. The fixed member 31 is provided with a through groove 312, through which the outer ring 71 passes and abuts against the movable member 32, providing support for the movable member 32 and increasing its support strength.

[0056] Example 2, please refer to Figure 11 The difference from Embodiment 1 is that the direction of the golden angle between the stirring shaft 22 and the geometric center line of the container 1 is opposite. In this embodiment, the end of the stirring shaft 22 near the motor 21 is away from the lifting mechanism 3, and the other end is inclined towards the stirring mechanism 2. When the operator needs to lift the stirring mechanism 2 upward, it can be pushed to the left and upward (as shown in the figure). The pushing force will be concentrated on the support component 7, which provides good rolling properties, reduces the resistance to pushing forward and upward, and maintains smooth lifting and lowering. By setting the direction of the golden angle and combining it with the support component 7, the lifting resistance of the stirring mechanism 2 can be reduced, the lifting and lowering of the stirring mechanism 2 can be made smooth, and the stirring effect and efficiency can be improved.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes, modifications, substitutions, and variations can be made to the present invention without departing from its spirit and scope, and all such changes, modifications, substitutions, and variations fall within the scope of the present invention as claimed.
