Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a building construction mortar mixing device. Background Technology

[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementitious materials with water in a certain proportion. It is also called mortar or cement paste. Common types of mortar include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar.

[0003] Currently, most mortar mixing devices used in construction are vertical or simple horizontal structures. Horizontal structures have problems such as inaccurate additive addition and inconvenient material collection due to fixed discharge height. In particular, the addition of powdered additives (such as admixtures and fibers) is often done by manual pouring, which makes it difficult to control the amount added and affects the quality of mortar. In addition, the traditional mixing device has a simple support structure and cannot adjust the discharge height, resulting in poor applicability. Summary of the Invention

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0018] like Figures 1-5As shown, this embodiment provides a mortar mixing device for construction, including a horizontal mixing drum 1. The horizontal mixing drum 1 has a mixing shaft 2 inside, with multiple mixing blades on the mixing shaft 2. A drive motor 3 for driving the mixing shaft 2 is installed at one end of the horizontal mixing drum 1. A feeding pipe 4 is located at the top of the horizontal mixing drum 1, and a discharge pipe 5 is located at the bottom of one end of the horizontal mixing drum 1. A control valve is installed on the discharge pipe 5. The device also includes a mounting base plate 6, with a support frame 7 at the top of the mounting base plate 6 supporting the horizontal mixing drum 1. The support frame 7 includes a fixed bracket 8 located outside the horizontal mixing drum 1 and a height-adjustable adjusting bracket 9. The tops of the adjusting bracket 9 and the fixed bracket 8 are connected to the same fixed frame cylinder 10 via bearings. An additive inlet 11 is located at the top of the horizontal mixing drum 1, and a metering nozzle for adding powdered additives into the horizontal mixing drum 1 is located at the top of the fixed frame cylinder 10 through the additive inlet 11. The quantitative additive addition mechanism 12 includes an additive guide sleeve 13 located at the top of the horizontal mixing drum 1 and at the additive inlet 11. The inside of the additive guide sleeve 13 is equipped with a transfer box 14 that matches the inner cavity of the additive guide sleeve 13. The bottom end of the transfer box 14 is equipped with an outlet 15 that matches the additive inlet 11. The top end of the additive guide sleeve 13 is equipped with a storage hopper 16 for replenishing additives into the transfer box 14. The top end of the transfer box 14 is equipped with a baffle plate 28. The output shaft of the drive motor 3 drives the mixing shaft 2 to rotate, and the mixing blades mix the mortar. The quantitative additive addition mechanism 12, through the horizontal movement of the transfer box 14, adds the powdered additives from the storage hopper 16 into the interior of the horizontal mixing drum 1 in the correct amount, achieving precise addition of the powdered additives and improving the mortar mixing quality. The adjusting bracket 9 in the support frame 7 can be raised and lowered to change the inclination angle of the horizontal mixing drum 1, facilitating material discharge.

[0019] The adjusting bracket 9 includes a U-shaped base 17 located at the top of the mounting base plate 6. Both sides of the top of the base 17 have receiving cavities 18. Inside each receiving cavity 18 is an I-shaped lifting support plate 19. A first hydraulic cylinder 20 is installed between the mounting base plate 6 and the base 17. The output shaft of the first hydraulic cylinder 20 is fixedly connected to the middle of the lifting support plate 19. The fixed frame cylinder 10 includes fixing rings 22 connected to the top of the lifting support plate 19 and the fixed bracket 8 via bearings. Multiple reinforcing connecting rods 23 are provided on the two fixing rings 22. Both ends of the multiple reinforcing connecting rods 23 are connected to the horizontal stirring drum 1. The ends of the fixed pull rings 24 are matched with the fixed pull rings 24. The cross-section of the fixed pull rings 24 is T-shaped. Both fixed rings 22 are fixedly connected to the outer wall of the horizontal mixing drum 1. One of the fixed rings 22 is provided with guide sliding holes 31 for multiple reinforcing connecting rods 23 to pass through. The output shaft of the first hydraulic cylinder 20 drives the bottom end of the lifting support plate 19 to be stored in the receiving cavity 18. At the same time, one of the fixed rings 22 moves along the reinforcing connecting rod 23 through the guide sliding holes 31, which can adjust the height of the adjusting bracket 9, thereby lowering the discharge pipe 5 of the horizontal mixing drum 1 and tilting the horizontal mixing drum 1 to facilitate discharge.

[0020] A horizontal shelf 21 is provided on the mounting base plate 6 near the discharge pipe 5, which facilitates the placement of receiving containers or tools and improves construction convenience.

[0021] The top of the storage hopper 16 is provided with a replenishment port 25, and a cover plate 26 is threaded onto the replenishment port 25. By opening the cover plate 26, additives can be added to the interior of the storage hopper 16 through the replenishment port 25.

[0022] The top of the reinforcing connecting rod 23 is equipped with a second hydraulic cylinder 27. The output shaft of the second hydraulic cylinder 27 passes through the additive guide sleeve 13 and is connected to the transfer box 14. The output shaft of the second hydraulic cylinder 27 drives the transfer box 14 to move along the additive guide sleeve 13, so that the additive port 11 corresponds to the outlet port 15, and the additive inside the transfer box 14 can be added to the interior of the horizontal mixing drum 1.

[0023] The transfer box 14 has an L-shaped adjustment plate 29 inside that abuts against the inner wall of the baffle plate 28. The transfer box 14 is threadedly connected to an adjustment screw 30 that is connected to the adjustment plate 29 via a bearing. By rotating the adjustment screw 30, the adjustment screw 30 is threadedly connected to the transfer box 14, and the adjustment screw 30 is connected to the adjustment plate 29 via a bearing, so the storage capacity of the transfer box 14 can be adjusted, further improving its applicability.

[0024] During operation, when adding additives, the additives enter the transfer box 14 under their own gravity inside the storage hopper 16. Rotating the adjusting screw 30, which is threadedly connected to the transfer box 14 and connected to the adjusting plate 29 via a bearing, allows adjustment of the storage capacity of the transfer box 14, further improving its applicability. The output shaft of the second hydraulic cylinder 27 drives the transfer box 14 to move along the additive guide sleeve 13, aligning the additive inlet 11 with the outlet 15, allowing the additives inside the transfer box 14 to be added into the horizontal mixing drum 1. During discharge, the output shaft of the first hydraulic cylinder 20 drives the bottom end of the lifting support plate 19 to be retracted into the receiving cavity 18. Simultaneously, one of the fixing rings 22 moves along the reinforcing connecting rod 23 via the guide sliding hole 31, adjusting the height of the adjusting bracket 9. This lowers the discharge pipe 5 of the horizontal mixing drum 1, tilting the horizontal mixing drum 1 for easier discharge.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
