Description

Technical Field

[0001] This utility model relates to the technical field of mortar mixing devices, specifically a mobile dry-mix mortar mixing device. Background Technology

[0002] Dry-mixed mortar is a widely used building material in construction projects. It consists of cement, sand, mineral admixtures, and additives mixed in a specific ratio at a specialized factory, then packaged as dry powder or transported in bulk to the construction site. When needed, it simply requires adding water according to the instructions and mixing thoroughly. Compared to traditional on-site mortar preparation, dry-mixed mortar offers advantages such as stable quality, environmental friendliness, energy efficiency, and ease of application, and has been widely used in various construction projects.

[0003] Currently, there are two main types of dry-mixed mortar mixing equipment used on construction sites: one is a fixed mixing plant, which is typically large and complex, requiring installation on a fixed foundation and cannot be moved. It is suitable for large-scale projects or long-term fixed construction sites, but for small and medium-sized sites or construction scenarios requiring multiple operations, fixed mixing plants suffer from difficulties in equipment transportation and low utilization rates. The other type is a small mobile mixer, which is usually equipped with wheels for easy relocation on the construction site. However, existing mobile mixers still have the following shortcomings in practical use: Most existing mobile mixers use a single-shaft mixing method, meaning that only one mixing shaft drives the mixing blades to rotate inside the mixing drum to complete the mixing operation, while the mixing drum itself remains stationary. This single-shaft mixing method easily creates dead zones within the mixing drum, resulting in insufficient mixing in some areas and uneven mixing effects. This is especially problematic for materials like dry-mix mortar, which require rapid and uniform mixing of dry powder and water. Single-shaft mixing often takes a long time to achieve the desired uniformity, impacting construction efficiency.

[0004] In view of the shortcomings of the existing technology, it is necessary to provide a mobile dry mortar mixing device that is compact, easy to move, has good mixing uniformity, has automatic water supply function and convenient unloading. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a mobile dry-mix mortar mixing device, comprising a base, with multiple wheel sets mounted on the bottom of the base, and rollers mounted on the base. The rollers are inclined, with the open end of each roller located at its highest point. A toothed ring is fixedly fitted onto the outer side of each roller, and a rotary drive mechanism is fitted onto the toothed ring. The rotary drive mechanism is connected to the base via a first support seat. A second support seat is fixed on the base, and a drive motor is mounted on the second support seat. The output end of the drive motor is connected to a rotating shaft, which extends into the interior of the rollers. The rotating shaft rotates in the opposite direction to the rotation of the drum; an agitator is mounted on the rotating shaft and is located inside the drum; a water tank is fixed on the base and a water pump is mounted on the water tank; a water pipe is connected to the outlet of the water pump and the end of the water pipe extends into the inside of the drum; two sets of fixed seats are mounted on the upper surface of the base, each set of fixed seats includes two fixed seats; the fixed seats are connected to support legs by pins; the rotation angle of the support legs is 180°; the support legs have a Z-shaped structure; and spiral blades are provided on the inner wall of the drum.

[0006] Furthermore, the rotary drive mechanism includes a ring seat and a low-speed motor mounted on the ring seat, the ring seat being sleeved on the outside of the gear ring and engaging with the gear ring in a transmission manner.

[0007] Furthermore, the wheel assembly includes a support plate, which is fixed to the base; a screw is vertically mounted on the support plate; and a wheel is mounted on the bottom end of the screw.

[0008] Furthermore, the stirring paddle has a U-shaped structure.

[0009] This utility model has the following beneficial effects: (1) This utility model uses the counter-rotation of the drum and the mixing paddle, combined with the spiral blades set on the inner wall of the drum, to make the material be subjected to shearing, tumbling and pushing action from two opposite directions inside the drum, forming a complex convection motion of multiple dimensions and multiple levels, effectively avoiding the existence of the mixing dead zone, significantly improving the mixing uniformity of each component of dry mortar, and greatly shortening the mixing time and improving the mixing efficiency.

[0010] (2) This utility model, through the wheel set at the bottom of the base and the Z-shaped support leg that can be rotated 180°, not only realizes the flexible movement and quick positioning of the entire device at the construction site, but also ensures the stability of the device by unfolding the support leg during the mixing operation, effectively preventing positional deviation caused by the rotation vibration of the drum.

[0011] 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

[0014] 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.

[0015] like Figures 1 to 6 As shown, this utility model provides a mobile dry mortar mixing device, including a base 1. The base 1 is the mounting base of this device, and multiple wheel sets 2 are installed on its bottom to realize the mobility of the entire device. In this embodiment, the number of wheel sets 2 is preferably four, which are respectively set at the four corners of the base 1 to ensure the stability of the device when moving.

[0016] Specifically, such as Figure 5As shown, wheel assembly 2 includes a support plate 201, a screw 203, and a wheel body 202. The support plate 201 is fixedly installed on the lower surface of the base 1. The screw 203 is vertically installed on the support plate 201, and the wheel body 202 is installed at the bottom end of the screw 203. By adjusting the screw 203, the device can be supported and positioned after it is moved to the working position, preventing the device from slipping during operation.

[0017] like Figure 1 and Figure 2 As shown, two sets of fixed seats 4 are installed on the upper surface of the base 1, each set of fixed seats 4 including two oppositely arranged fixed seats 4. Each fixed seat 4 is rotatably connected to a support leg 3 via a pin, and the support leg 3 can rotate around the pin, with a rotation angle of 180°. Preferably, the support leg 3 has a Z-shaped structure. When the device moves, the support leg 3 rotates to a retracted state and fits against the upper surface or side of the base 1; when the device reaches the working position, the support leg 3 rotates and unfolds to a vertical support state, with its bottom end supporting the ground, working together with the wheel set 2 to enhance the stability of the device during operation.

[0018] like Figure 1 and Figure 3 As shown, a drum 6 is mounted on the base 1, serving as the mixing container for dry-mixed mortar. The drum 6 is inclined, with its open end located at the higher end and its closed end at the lower end. This inclined arrangement facilitates the flow of material towards the discharge port under gravity during mixing, simplifying unloading. Spiral blades 601 are fixedly mounted on the inner wall of the drum 6, extending spirally along its inner wall. These blades drive the material to axially tumble and propel it forward as the drum 6 rotates, improving mixing uniformity.

[0019] A toothed ring (not shown in the attached drawing) is fixedly sleeved on the outer wall of the roller 6, but it is a necessary structure for achieving rotary drive. A rotary drive mechanism 7 is fitted onto the toothed ring, and the rotary drive mechanism 7 is fixedly connected to the base 1 via a first support seat 5. In this embodiment, the rotary drive mechanism 7 includes a ring seat and a low-speed motor mounted on the ring seat. The specific structure is conventional technology in the art and is not shown in detail in the figure. The ring seat is sleeved on the outer side of the toothed ring, and the inner wall of the ring seat is provided with transmission teeth or friction transmission wheels that mesh with the toothed ring. After the low-speed motor is started, the low-speed motor drives the ring seat to rotate, which in turn drives the roller 6 to rotate at low speed around its own axis via the toothed ring. The first support seat 5 is fixedly installed on the upper surface of the base 1 to provide stable support for the rotary drive mechanism 7.

[0020] like Figure 1 and Figure 4As shown, a second support base 8 is also fixed on the base 1, and a drive motor 9 is installed on the second support base 8. The output end of the drive motor 9 is connected to a rotating shaft 10, which extends into the interior of the drum 6 along the axial direction. A stirring paddle 11 is fixedly installed on the rotating shaft 10, and the stirring paddle 11 is located inside the drum 6. Preferably, the stirring paddle 11 has a U-shaped structure, with its U-shaped bottom fixed to the rotating shaft 10 and its two side walls extending outward to increase the contact area with the material and the stirring range. In this embodiment, the rotation direction of the drive motor 9 is opposite to the rotation direction of the drum 6 driven by the rotary drive mechanism 7. That is, when the drum 6 rotates clockwise, the stirring paddle 11 rotates counterclockwise; and vice versa. This reverse rotation method causes the spiral blades 601 on the inner wall of the drum 6 to drive the material to move in one direction, while the stirring paddle 11 drives the material to move in the opposite direction, thereby forming a strong shearing and convection stirring effect inside the drum 6, which significantly improves the mixing uniformity of the components of the dry-mixed mortar.

[0021] like Figure 6 As shown, a water tank 12 is also fixedly installed on the base 1. The water tank 12 is used to store water for stirring. A water pump (not shown in the figure) is installed on the water tank 12. A conventional micro water pump can be used. The inlet end of the water pump is connected to the inside of the water tank 12, and the outlet end of the water pump is connected to a water pipe 13. The end of the water pipe 13 extends into the inside of the drum 6 from the open end of the drum 6. During the stirring process, the water pump is started, and the water in the water tank 12 is pumped into the drum 6 in a metered manner to achieve automatic water supply and avoid the measurement error and operational inconvenience caused by manual water addition.

[0022] The working process of this utility model will be described in detail below with reference to the accompanying drawings: In its initial state, the device moves to the construction position via the wheel set 2 at the bottom of the base 1. After moving into position, the screw 203 at the bottom of the wheel set 2 is adjusted for initial positioning. Then, the Z-shaped support leg 3 is rotated 180° from the folded state to the unfolded support state, so that the bottom end of the support leg 3 is firmly supported on the ground, thus completing the fixation of the device together with the wheel set 2.

[0023] Subsequently, the operator adds dry powder materials such as cement, sand, and fly ash to the inside of drum 6 from the higher end of the opening, according to the specified proportions. Next, the water pump on water tank 12 is started, pumping water into drum 6 through water pipe 13 in a metered manner. Simultaneously, the drive motor 9 and the low-speed motor on the rotary drive mechanism 7 are started. Drive motor 9 drives shaft 10 to rotate at high speed, which in turn drives U-shaped agitator 11 to rotate inside drum 6; at the same time, rotary drive mechanism 7 drives drum 6 to rotate in the opposite direction at a lower speed than agitator 11 via a gear ring. Because drum 6 is inclined and its opening is at a higher position, the material will not immediately overflow under gravity. The spiral blades 601 on the inner wall of drum 6 slowly push the material from the lower end to the higher end as drum 6 rotates, working in conjunction with the reverse stirring action of agitator 11 to create a complex multi-directional, multi-layered flow of material within drum 6, ensuring that the dry powder and water are thoroughly and evenly mixed in a short time.

[0024] After mixing is complete, turn off the drive motor 9 and the rotary drive mechanism 7 to stop the drum 6 from rotating. At this time, the higher end of the opening of the drum 6 can be oriented towards the discharge container. With the help of the tilt angle of the drum 6 and the guiding action of the spiral blades 601, the mixed wet mortar can be smoothly discharged from the opening. If cleaning is required, clean water can be injected into the drum 6 through the water tank 12 and the water pipe 13. Then, restart the mixing paddle 11 and the drum 6 to rotate in opposite directions to achieve automatic cleaning. The wastewater after cleaning can be discharged from the opening.

[0025] In summary, the mobile dry mortar mixing device provided by this utility model has a compact structure and is easy to move. Through the counter-rotation of the drum 6 and the mixing paddle 11 and the guiding effect of the spiral blade 601, it achieves a high-efficiency and uniform mixing effect. At the same time, it achieves automatic water supply through the water tank 12 and water pipe 13, and is suitable for occasions such as construction sites that require frequent movement and rapid mixing of dry mortar.

[0026] 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.
