Abstract

This utility model discloses a material mixing device for construction, belonging to the technical field of mixing devices. The utility model includes a mounting frame and a drive source. The mounting frame has a cross-shaped groove, on which a first sliding block and a second sliding block are slidably mounted. The first and second sliding blocks are fixedly connected by a connecting rod. Both the first and second sliding blocks have through grooves, and a sleeve is interference-fitted into the through groove of the second sliding block. Through the structure of the mounting frame, the first sliding block, the connecting rod, and the sleeve, the mixing blades can move forward, backward, left, and right in four directions within the horizontal plane of the material container.

Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, specifically a material mixing device for construction. Background Technology

[0002] Mixing devices for building materials are used to mix different types of building materials evenly to achieve the required texture and properties during the construction process. Building materials that need to be mixed include cement, cement mortar, gypsum, and putty powder, etc. In the construction field, handheld electric mixers are commonly used equipment for material mixing operations. A Chinese utility model patent (publication number: CN222328620U) discloses a mixing device for building materials. When mixing building materials, the device can be fixed to the upper part of the wall of the material bucket. The material bucket itself supports the device, reducing the workload of the workers. Moreover, it can be fixed to material buckets of different diameters, making it highly adaptable.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, the existing device can only move the stirring blade vertically and cannot adjust the displacement in the horizontal direction (left and right, front and back). This causes the stirring blade to always rotate around the central axis of the material bucket, which makes it difficult for the coating in the inner wall edge area of ​​the material bucket to be fully stirred, and it is easy to have stirring dead corners, resulting in uneven mixing of materials. Therefore, in order to address the above situation, a material mixing device for construction is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a material mixing device for construction. Through the design of the mounting frame, the first sliding block, the connecting rod and the sleeve, the mixing blade can move in four directions (front, back, left and right) within the horizontal plane of the material bucket. This allows the drive source to actively approach the inner edge area of ​​the material bucket and directly stir the dead corners of traditional mixing. This ensures that materials such as paint and mortar can be fully sheared and mixed from the center to the edge, solving the problem of easy formation of dead corners and uneven mixing of materials.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a material mixing device for construction, including a mounting frame and a drive source. The mounting frame has a cross groove, on which a first sliding block and a second sliding block are slidably mounted respectively. The first sliding block and the second sliding block are fixedly connected by a connecting rod. Both the first sliding block and the second sliding block have through grooves, and a sleeve is interference-fitted into the through groove of the second sliding block.

[0007] The drive source is fixed to the top of the first sliding block, and the output shaft of the first sliding block is fixed with a stirring rod. The stirring rod is in clearance fit with the through groove, and a stirring blade is fixed to one end of the stirring rod that extends out of the through groove.

[0008] Furthermore, the mounting frame includes an upper circular plate and a lower circular plate, which are fixedly connected by a connecting block. The upper and lower circular plates are respectively provided with cross grooves. The first sliding block slides on the cross groove on the upper circular plate, and the second sliding block slides on the cross groove on the lower circular plate.

[0009] Furthermore, handles are fixed on both sides of the first sliding block, and the handles are in the shape of a "Z".

[0010] Furthermore, four abutment rods are fixed to the outer wall of the sleeve, arranged in a cross shape.

[0011] Furthermore, a circular groove is provided at the bottom of the lower circular plate, and a rubber pad is placed inside the circular groove.

[0012] This utility model has the following beneficial effects:

[0013] This invention, through the design of a mounting frame, a first sliding block, a connecting rod, and a sleeve, allows the stirring blade to move in four directions (front, back, left, and right) within the horizontal plane of the material container. This enables the drive source to actively approach the inner edge area of ​​the material container, directly stirring the traditionally dead corners of the mixing process. This ensures that materials such as coatings and mortars are fully sheared and mixed from the center to the edge, effectively eliminating problems such as concentration stratification and particle sedimentation caused by insufficient mixing of materials at the edges, and significantly improving the uniformity of mixing.

[0014] This invention, through the structural design of the sleeve and the contact rod, allows the contact rod to contact the barrel wall before the stirring blade moves within the material barrel, thus effectively preventing the stirring blade from colliding with the barrel wall during rotation and causing damage to the stirring blade, which would affect its service life.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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] Please see Figure 1-5 This utility model provides a technical solution: a material mixing device for construction, including a mounting frame 1 and a drive source 6. The mounting frame 1 has a cross groove 13, on which a first sliding block 2 and a second sliding block 20 are slidably mounted respectively. The first sliding block 2 and the second sliding block 20 are fixedly connected by a connecting rod 3. Both the first sliding block 2 and the second sliding block 20 have through grooves 21. A sleeve 4 is interference-fitted into the through groove 21 of the second sliding block 20. The sleeve 4 is made of hard plastic and is cylindrical.

[0024] Handles 7 are fixed on both sides of the first sliding block 2. The handles 7 are "Z" shaped and ergonomically designed. The surface is covered with a non-slip rubber sleeve, which can provide a comfortable grip for construction workers and prevent their hands from slipping during operation.

[0025] The drive source 6 is fixed to the top of the first sliding block 2. The output shaft of the first sliding block 2 is fixed with a stirring rod 60. The stirring rod 60 is clearance-fitted with the through groove 21. A stirring blade 61 is fixed to one end of the stirring rod 60 that extends out of the through groove 21.

[0026] The drive source 6 uses a DC geared motor, which features stable speed and high torque, meeting the power requirements for material mixing in construction. The motor's output shaft is connected to the mixing rod 60 via a key, ensuring reliable power transmission and preventing slippage during mixing. The mixing rod 60 is made of alloy steel, possessing high strength and rigidity, and can withstand large torques during mixing. The mixing rod 61 has a three-bladed propeller structure with specially treated blade surfaces that are corrosion-resistant and wear-resistant. This structural design generates strong vortices during mixing, ensuring thorough mixing of materials.

[0027] Mounting frame 1 includes an upper circular plate 10 and a lower circular plate 11, which are fixedly connected by a connecting block 12. The upper circular plate 10 and the lower circular plate 11 are respectively provided with cross grooves 13. The first sliding block 2 slides on the cross groove 13 on the upper circular plate 10, and the second sliding block 20 slides on the cross groove 13 on the lower circular plate 11. The bottom of the lower circular plate 11 is provided with an annular groove, and a rubber pad is provided in the annular groove.

[0028] There are four connecting blocks 12, which are arranged in a rectangular shape. The upper circular plate 10 and the lower circular plate 11 are firmly connected by welding to form a stable three-dimensional frame structure. The cross grooves 13 opened on the upper circular plate 10 and the lower circular plate 11 can be designed with a T-shaped cross section. This shape design can effectively prevent the first sliding block 2 and the second sliding block 20 from falling out of the groove during the sliding process. At the same time, it can also enhance the lateral support force on the sliding blocks and ensure that the sliding process is smooth and stable.

[0029] Both the first sliding block 2 and the second sliding block 20 are made of engineering plastic material. This material has good wear resistance and self-lubrication, which can reduce friction with the cross groove 13 and extend service life.

[0030] Construction workers hold the "Z"-shaped handle 7 and place the mounting frame 1 above the material bucket. At this time, the rubber pad in the annular groove at the bottom of the lower circular plate 11 is in close contact with the top edge of the material bucket.

[0031] After connecting the external power supply to the drive source 6 and turning on the switch of the drive source 6, the motor output shaft drives the stirring rod 60 to rotate, and the stirring rod 60 drives the stirring blade 61 to rotate at high speed, performing preliminary stirring of the material in the material bucket. Since the first sliding block 2 and the second sliding block 20 are respectively slidably installed on the cross groove 13 of the upper circular plate 10 and the lower circular plate 11, and are fixedly connected by the connecting rod 3, the construction personnel can push the handle 7 to make the first sliding block 2 and the second sliding block 20 slide in the cross groove 13. The sliding of the first sliding block 2 drives the drive source 6 and the stirring rod 60 to move. By pushing the handle 7 back and forth and left and right, the stirring blade 61 can move horizontally back and forth and left and right in the material bucket, realizing the stirring of the material at the edge of the material bucket, making up for the deficiency of traditional stirring devices that can only stir in the central area, so that the material is more fully and evenly mixed.

[0032] The outer wall of the sleeve 4 is fixed with four abutment rods 5 arranged in a cross shape. The ends of the abutment rods 5 are hemispherical. The hemispherical end design can prevent scratches on the barrel wall when in contact with it, thus protecting the barrel wall.

[0033] Furthermore, the distance between the contact rod 5 and the barrel wall is less than the distance between the stirring blade 61 and the barrel wall.

[0034] The force generated by the contact rod 5 in contact with the barrel wall will give the construction personnel feedback, indicating that the stirring blade 61 is close to the limit position of the barrel wall, preventing excessive movement from damaging the equipment and material barrel, thus achieving dual protection for the stirring device and the material barrel.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
