Description

Technical Field

[0001] This utility model relates to the technical field of mixer components, specifically to a mixing shaft and a bidirectional long mixing arm. Background Technology

[0002] A concrete mixer is a machine that mixes cement, sand, aggregates, and water to produce concrete. It mainly consists of a mixing drum, feeding and unloading mechanisms, a water supply system, and a prime mover. Based on the nature of operation, it can be classified as intermittent or continuous; based on the structure of the mixing drum, it can be classified as pear-type, drum-type, double-cone, disc-type vertical shaft, and groove-type horizontal shaft, etc.

[0003] A twin-shaft horizontal mixer is a type of concrete mixer that typically has two sets of horizontal shafts as the main mixing shafts, with wear-resistant liners forming the mixing chamber above and below.

[0004] Traditional technologies employ both cylindrical mixing shafts, such as the high-wear-resistant alloy mixing arm for concrete mixing equipment (CN202223120271.X), and polygonal shafts, such as the mixing arm for a concrete mixer (CN202320568549.5). The polygonal shaft design aims to prevent relative rotation of the mixing arms on the shaft. Most existing mixing arms are bolted to the mixing shaft, as in the mixing arm for a concrete mixer (CN201720429643.7), requiring paired mixing arms and mounting bases, and at least four sets of bolts for fixation. On the one hand, the mixing shaft cannot provide axial restraint for the mixing arms, making them prone to misalignment in the event of a large impact. On the other hand, more mixing arms are needed to achieve a three-dimensional mixing effect, requiring more mounting bases and positioning bolts, which fails to provide convenient installation and material savings.

[0005] To address these issues, we provide a stirring shaft and a bidirectional long stirring arm. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a stirring shaft and a bidirectional long stirring arm to solve the technical problems of the inability to limit the stirring arm axially and the inconvenience of installation.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stirring shaft, including a main shaft and a mounting part, wherein the vertical cross-section of the main shaft is hexagonal, and connecting posts are provided at both ends, and connecting holes are provided on the connecting posts; the main shaft and the mounting part are integrally formed; multiple sets of mounting parts are provided on the main shaft;

[0008] The mounting section has a hexagonal vertical cross-section, and its dimensions are smaller than those of the main shaft section.

[0010] In a further technical solution, the auxiliary reinforcement includes a bulge body and an ear plate, with the bulge body and the ear plate integrally connected; a positioning hole is provided on the ear plate, and a positioning bolt is installed in the positioning hole and connected to the mounting part.

[0011] A bidirectional long stirring arm includes a hinge body and a long swing arm. The outer surface of the hinge body is fixedly connected to the long swing arm. The hinge body is detachably installed in the mounting part and clamped to the outside of the bulge body.

[0012] The long swing arm has mounting holes, which are used to connect the stirring blades by installing locking components.

[0013] The long swing arms are provided in two sets, and the two sets of long swing arms are in the same direction and have the same angle with the central axis of the main shaft.

[0014] In a further technical solution, the hinge body includes a first part and a second part, the second part being provided with a hinge interface, and the first part being provided with a connecting cylinder; the connecting cylinder and the hinge interface are connected by a mounting connecting shaft, and a sealing cap is installed at the end of the connecting shaft;

[0015] The first and second parts are respectively connected to two sets of long swing arms; the axial length of the first and second parts mounted on the main shaft is adapted to the length of the mounting part.

[0016] In a further technical solution, both the ends of the first and second parts away from the hinge interface are provided with connecting parts, and positioning holes are opened in the connecting parts, and locking bolts are installed in the positioning holes.

[0019] An arc-shaped groove is provided on the long arm plate, and a positioning component is installed in the arc-shaped groove for connecting the stirring blade.

[0020] In a further technical solution, the outer side of the hinge body is arc-shaped, the end face of the position post away from the hinge body is an arc surface, and the arc surface and the arc groove are arranged with the same center.

[0021] In a further technical solution, limiting posts are provided on both sides of the long arm plate, and the limiting posts are located at the bottom of the arc-shaped groove to limit the rotation angle of the stirring blade.

[0022] Compared with existing technologies, it has the following advantages:

[0023] This invention utilizes a hexagonal main shaft and a hexagonal mounting section, staggered at 30°, to achieve effective installation positioning and axial limitation of the hinged body, eliminating the need for additional fixing components.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0041] Example 1

[0042] Please see Figure 1-8 This invention provides a technical solution, such as... Figure 1 As shown, a stirring shaft includes a main shaft part 1 and a mounting part 3. The vertical cross-section of the main shaft part 1 is hexagonal, and connecting posts 2 are provided at both ends, with connecting holes provided on the connecting posts 2. The main shaft part 1 and the mounting part 3 are integrally formed. Multiple sets of mounting parts 3 are provided on the main shaft part 1.

[0043] The mounting part 3 has a vertical cross-section of hexagon, and its size is smaller than that of the vertical cross-section of the main shaft part 1;

[0044] like Figure 2 As shown, the hexagon of the mounting part 3 forms a 30° angle with the hexagon of the main shaft part 1. The smaller mounting part on the main shaft part can limit the axial displacement of the subsequent hinge body and prevent the stirring arm from swaying along the stirring shaft. An auxiliary reinforcing member 4 is installed on the mounting part 3, and the auxiliary reinforcing member 4 is detachably connected to the mounting part 3.

[0045] See Figure 1 and 3The auxiliary reinforcing member 4 includes a bulge body 41 and an ear plate 42, which are integrally connected. A positioning hole is provided on the ear plate 42, and a positioning bolt 43 is installed in the positioning hole and connected to the mounting part 3. The auxiliary reinforcing member is provided to increase the mounting contact surface of the hinge body in the mounting part and to prevent rotation along the axis. The auxiliary reinforcing member can also be configured in a tangential direction (not shown) to increase the radial contact surface and prevent axial sliding.

[0046] See Figure 4-8 As shown, a bidirectional long stirring arm includes a hinge body 5 and a long swing arm 6. The outer surface of the hinge body 5 is fixedly connected to the long swing arm 6. The hinge body 5 is detachably installed in the mounting part 3 and clamped outside the bulge body 41.

[0047] The long swing arm 6 has a mounting hole 61, which is used to connect the stirring blade 20 through the mounting locking component 7. The locking component is a locking bolt, screw, or other connecting component, used to fasten the stirring blade to the long swing arm.

[0048] The long swing arms 6 are arranged in two sets, with both sets pointing in the same direction and at the same angle to the central axis of the main shaft 1. That is, the two sets of long swing arms are not symmetrical about the axis of the main shaft. This ensures that at any given time, the stirring blades at different positions on the two stirring arms operate in different phases and are not coplanar. This allows for complex motion; after material is thrown up by one blade, it is caught in mid-air by a blade on another axis and in another phase, and pushed in another direction. This creates a relatively complex three-dimensional convection motion, thereby achieving efficient mixing.

[0049] As shown in 6 and 8, the hinge body 5 includes a first part 51 and a second part 52. The second part 52 is provided with a hinge interface, and the first part 51 is provided with a connecting cylinder. The connecting cylinder and the hinge interface are connected by a mounting connecting shaft 53, and a sealing cap 54 is installed at the end of the connecting shaft 53.

[0050] The first split body 51 and the second split body 52 are respectively connected to two sets of long swing arms 6; the axial length of the first split body 51 and the second split body 52 installed on the mounting part 3 is adapted to the length of the mounting part 3 to prevent axial shaking.

[0051] like Figure 8 As shown, both the first split body 51 and the second split body 52 are provided with a connecting part 55 at the ends away from the hinge interface, and a positioning hole is provided in the connecting part 55, and a locking bolt 56 is installed in the positioning hole.

[0052] The first split body 51 and the second split body 52 are provided with folded panels 57 facing each other, and a notch 58 is provided in the folded panel 57. The notch 58 is adapted to abut against the bulge body 41, such as... Figure 5 As shown.

[0053] like Figure 6 As shown, the long swing arm 6 includes a position post 62 and a long arm plate 63. The position post 62 is integrally connected to the hinge body 5. The long arm plate 63 is fixedly connected to the end of the position post 62 away from the hinge body 5, and a mounting hole 61 is provided on the long arm plate 63.

[0054] An arc-shaped groove 64 is formed on the long arm plate 63, and a positioning element 8 is installed in the arc-shaped groove 64 for connecting the stirring blade 20. During installation, the first and second parts are first connected via the top hinge interface and connecting cylinder, then connected by a connecting shaft, and sealed caps are installed on both sides of the hinge interface. The hinge body is then installed on the mounting part, such as... Figure 4 As shown, the connection is then secured by installing locking bolts and nuts on the connecting part.

[0055] This invention utilizes a hexagonal main shaft and a hexagonal mounting section, staggered at 30°, to achieve effective installation positioning and axial limitation of the hinged body, eliminating the need for additional fixing components. Furthermore, auxiliary reinforcing components are incorporated to secure the hinged body to the mounting section, preventing relative rotation. The two sets of stirring arms are oriented in the same direction but asymmetrically distributed, allowing for stirring on both stirring surfaces, preventing material accumulation, and resulting in a more unified and efficient stirring process.

[0056] Example 2

[0057] like Figure 9 and 10 As shown, this is another embodiment of the present invention, based on embodiment 1, as follows: Figure 9 As shown, the outer side of the hinge body 5 is arc-shaped, and the end face of the position post 62 away from the hinge body 5 is an arc surface 65. The arc surface 65 and the arc groove 64 are arranged with the same center.

[0058] like Figure 10 As shown, limiting posts 67 are provided on both sides of the long arm plate 63. The limiting posts 67 are located at the bottom of the arc-shaped groove 64 and are used to limit the rotation angle of the stirring blade 20. The limiting posts can also be set as bent right angles to constrain the stirring blade.

[0059] Stirring blades Figure 9 As shown, it includes a clamping plate and a working plate. The working plate is usually rectangular and may have guide holes at the top. The clamping plate is mounted on the long arm plate by opening position holes.

[0060] This invention features an arc surface to facilitate angle adjustment during the installation of the stirring blades. Additionally, the setting of a limiting post restricts the adjustment limit of the stirring blades and prevents the locking or positioning components from colliding and breaking during operation, which could cause the stirring blades to crash into the inner wall of the mixing chamber.

[0061] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
