Description

Technical Field

[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementing materials (cement, lime paste, clay, etc.) with water in a certain proportion. It is also called mortar or plaster and has a variety of uses in the construction field.

[0003] Before use, mortar requires mixing various raw materials. Then, the mixed mortar is laid using a laying device to give the floor or wall surface waterproof and wear-resistant properties. Therefore, it is very important whether the mortar is fully mixed during the mixing process.

[0004] Existing mixing devices typically consist of a mixing tank, a rotating rod located inside the mixing tank, and multiple stirring rods perpendicular to the rotation. The rotating rod is driven by a motor, which in turn drives the stirring rods to rotate, thereby mixing the mortar raw materials in the mixing tank. However, this method only keeps the stirring blades rotating on a certain horizontal plane, and the area of ​​contact between the rotation trajectory and the mortar raw materials is limited, resulting in insufficient mixing of the mortar raw materials and low mixing efficiency.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0038] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a mortar mixing device for laying ground mortar, including a hollow mixing tank 1, a rotating rod 2 rotatably installed in the mixing tank 1, a stirring rod 3, and a driving part 4 connected to the rotating rod 2. The stirring rod 3 is a rod group composed of a first rod body 301 and a second rod body 302. The extension directions of the first rod body 301 and the second rod body 302 are perpendicular, and the second rod body 302 is rotatably installed on the first rod body 301.

[0039] The first rod 301 extends in the diametrical direction of the rotation trajectory of the rotating rod 2. A sliding groove extending along its own length is provided in the first rod 301. A meshing rack 5 and a gear 501 are provided in the sliding groove. The rack 5 and the sliding groove are slidably engaged. The gear 501 is connected to one end of the second rod 302.

[0040] The rack 5 is connected to a linkage component at the end away from the rotating rod 2. The linkage component drives the rack 5 to slide in the groove when the rotating rod 2 rotates.

[0041] In this scheme, the mixing tank 1 is equipped with an input pipe and an output pipe that are connected to its interior, so as to input the raw materials of mortar and output the mixed mortar. The output pipe is equipped with a valve to open or close the output pipe.

[0042] Multiple second rods 302 and gears 501 are arranged along the length of the first rod 301 to increase the contact area with the mortar raw materials, thereby improving the efficiency and quality of mixing.

[0043] Specific usage methods and working principles:

[0044] Step 1: Close the valve, and then input the raw materials required for mortar preparation into mixing tank 1 through the input pipe;

[0045] Step two: Since the first rod 301 extends in the diameter direction of the rotation trajectory of the rotating rod 2, the first rod 301 and the second rod 302 on the first rod 301 can fully contact the mortar raw materials. The rotating rod 2 and the first rod 301 are driven to rotate by the driving unit 4, thereby performing primary mixing of the mortar. At the same time, the rotation of the first rod 301 forms a rotation trajectory A, and the rotation of multiple second rods 302 forms multiple rotation trajectories B. The diameters of the multiple rotation trajectories B are equally spaced and their diameter lengths decrease, further expanding the contact area with the mortar raw materials.

[0046] Step 3: During the rotation of the rotating rod 2, the linkage component causes the rack 5 to slide in the groove. When the rack 5 slides, it meshes with the gear 501, thereby driving the gear 501 to rotate, which in turn drives the second rod 302 connected to the gear 501 to rotate, thus performing secondary mixing of the mortar. At the same time, the second rod 302 rotates to form a rotation trajectory C, and the rotation trajectory C is located on the rotation trajectory B. That is, the second rod 302 rotates around the rotating rod 2 while being in a state of rotation, which further improves the mixing efficiency.

[0047] When using this application to mix mortar raw materials, the first rod 301 and the second rod 302 are driven by the drive unit 4 to rotate around the rotating rod 2 and form rotation trajectories A and B with different diameters and lengths. At the same time, under the driving action of the linkage component, the second rod 302 is driven to rotate to form a rotation trajectory C with the rotation trajectory B as the path, thereby increasing the contact area between the mixing rod 3 and the mortar raw materials, and thus improving the efficiency of mixing the mortar raw materials.

[0048] In this embodiment, the linkage component includes a first link 6, a second link 601, and a hinge plate 602. One end of the first link 6 and the second link 601 are relatively close to each other and are both hinged to the hinge plate 602, and the other end is respectively hinged to both ends of the rotating rod 2 and slidably engaged.

[0049] The hinge plate 602 is connected to the end of the rack 5 away from the rotating rod 2.

[0050] In this scheme, the first link 6, the second link 601, the hinge plate 602 and the rotating rod 2 form a trapezoidal structure, and the hinge points correspond to the four corners of the trapezoidal structure respectively.

[0051] Since the lengths of the first link 6 and the second link 601 are constant, when their ends away from the hinge plate 602 are relatively close, the hinge plate 602 will move away from the rotating rod 2, thereby driving the rack 5 to move synchronously in the same direction. Conversely, when the ends of the first link 6 and the second link 601 away from the hinge plate 602 are relatively far apart, the hinge plate 602 will move closer to the rotating rod 2, which will also drive the rack 5 to move synchronously in the same direction. This drives the gear 501 and the second rod 302 to rotate by driving the rack 5.

[0052] In this embodiment, the rotating rod 2 includes an inner rod body 201 and an outer rod body 202 sleeved outside the inner rod body 201. The inner rod body 201 and the outer rod body 202 are slidably engaged, and the inner rod body 201 can slide along the length direction of the outer rod body 202.

[0053] The ends of the first link 6 and the second link 601 that are away from the hinge plate 602 are respectively hinged to the outer rod 202 and the inner rod that are away from each other.

[0054] In this scheme, the first connecting rod 6 is connected to the outer rod body 202. Since the outer rod body 202 is rotatably connected to the mixing tank 1, the height position of the connection between the first connecting rod 6 and the outer rod body 202 will not change.

[0055] The second link 601 is connected to the inner link 201, and the inner link 201 can slide along the length direction of the outer link 202, so that the connection between the second link 601 and the inner link 201 can be close to or far away from the connection between the first link 6 and the outer link 202, thereby shortening or increasing the distance between the first link 6 and the second link 601 at the end away from the hinge plate 602.

[0056] In this embodiment, the driving unit 4 includes a first rotating plate that rotates on the mixing tank 1. The first rotating plate is sleeved on the outer side of the inner rod body 201. The outer side wall of the inner rod body 201 is provided with two sections of threads with opposite helical directions. The inner side wall of the first rotating plate is provided with a slider that slides in cooperation with the threads.

[0057] Among them, the two threads on the outer side wall of the inner rod 201 constitute a reciprocating thread, and the cooperation between the slider and the thread is similar to the application of a reciprocating screw. The reciprocating screw is a mature existing technology, so this application does not elaborate on how the thread and the slider cooperate in detail.

[0058] In this scheme, the rotation of the first rotating plate causes the slider to slide in the thread, thereby driving the inner rod 201 to rotate. Under the action of the two threads, the inner rod 201 moves up and down reciprocally. This, in turn, drives the rack 5 to move laterally in the slide groove through the cooperation of the first connecting rod 6, the second connecting rod 601 and the hinge plate 602. This, in turn, drives the gear 501 and the second rod 302 to rotate reciprocally, further enhancing the mixing effect of the rotation of the second rod 302.

[0059] In this embodiment, the driving unit 4 further includes a second rotating plate that rotates on the mixing tank 1, and the second rotating plate is connected to the outer rod 202 in a transmission manner.

[0060] In this design, the second rotating plate is coaxially connected to the outer rod 202. The rotation of the second rotating plate causes the outer rod 202 to rotate, which in turn causes the stirring rod 3 to rotate around the outer rod 202.

[0061] In this embodiment, the first rotating plate and the second rotating plate are coaxially mounted, and a first bevel gear 401 is provided on the opposite side of the first rotating plate and the second rotating plate.

[0062] The drive unit 4 also includes a second bevel gear 402 located between the two first bevel gears 401. The second bevel gear 402 meshes with the two first bevel gears 401 respectively, and the second bevel gear 402 is connected to the motor 7 for transmission.

[0063] In this scheme, since the first bevel gear 401 and the second bevel gear 402 rotate, the second bevel gear 402 is driven to rotate by the motor 7, which in turn drives the two first bevel gears 401 to rotate. That is, it drives the first rotating plate and the second rotating plate to rotate, so that the rotation trajectories A, B and C occur simultaneously.

[0064] In this embodiment, the extension direction of the second rod 302 is parallel to the extension direction of the rotating rod 2.

[0065] In this scheme, since the extension direction of the second rod 302 is parallel to the extension direction of the rotating rod 2, when the second rod 302 rotates, the rotation trajectory C is in the same direction as the rotation trajectories A and B. At this time, the rotation trajectory C can be regarded as the extension range of the rotation trajectories A and B, that is, the contact area with the mortar raw materials is expanded.

[0066] In this embodiment, a scraper 8 is provided on the side of the hinge plate 602 away from the rack 5. The side of the scraper 8 away from the hinge plate 602 is an arc surface and is in contact with the inner wall of the mixing tank 1.

[0067] In this scheme, during rotation, the scraper 8 scrapes off the mortar material adhering to the inner wall of the mixing tank 1 to improve the degree of mixing of the mortar material.

[0068] In this embodiment, an elastic support member 801 is provided between the scraper 8 and the hinge plate 602. When the elastic support member 801 is in a naturally extended state, the scraper 8 is away from the direction where the hinge plate 602 is located.

[0069] In this solution, under the elastic force of the elastic support 801 and the centrifugal force generated by rotation, the scraper 8 is in contact with the inner wall of the mixing tank 1. The elastic support is a flexible support to reduce the damage caused by the scraper 8 being in contact with the inner wall of the mixing tank 1, thereby improving the durability of the mixing tank 1.

[0070] Example 2: Please refer to Figure 6 The difference between Embodiment 2 and Embodiment 1 is that the projection of the extension direction of the second rod 302 is perpendicular to the extension direction of the rotating rod 2.

[0071] In this scheme, since the projection of the extension direction of the second rod 302 is perpendicular to the extension direction of the rotating rod 2, when the second rod 302 rotates, the rotation trajectory C is perpendicular to the rotation trajectories A and B. Thus, by mixing in two different rotation directions, the mortar raw materials can be better mixed.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
