Description

Technical Field

[0001] This utility model relates to the field of premixed mortar technology, and in particular to a batching mechanism for premixed mortar processing. Background Technology

[0002] Ready-mixed mortar, as an important cementitious material in construction engineering, has properties (such as strength, durability, and workability) that directly depend on the proportions of its components, such as cement, sand, and water. The batching process, which involves measuring and mixing materials with different physical properties (such as granular sand and gravel, powdered cement, and water), is the core step in ensuring the quality of ready-mixed mortar.

[0003] However, in existing technologies, cement, sand, and water are directly added to the mixing tank after weighing for mixing. In existing flat-mouth vertical mixers, the position and posture of the agitator are fixed, resulting in a low mixing speed. Especially for some premixed mortars that require the addition of admixtures, the amount of admixtures is relatively small compared to the main components. When the mixing rate is slow, the admixtures are very easy to clump together and coat the surface of the sand particles, failing to play their corresponding role and directly affecting the fluidity or cohesiveness of the mortar. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a batching mechanism for premixed mortar processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a batching mechanism for premixed mortar processing, comprising a mixing tank and a conical cover, wherein the upper side of the conical cover is provided with an inlet pipe for adding cement and sand and a tilting plate for adding water, a mixing mechanism is fixedly installed in the middle of the conical cover, the mixing mechanism extends into the inner cavity of the mixing tank, and a feeding mechanism is provided at the lower opening of the mixing tank. The mixing mechanism includes a power component, a cross, an extension component, an inclined shovel component, an L-shaped rod, and a mixing shovel. Four sets of extension components are fixedly connected to the four ends of the cross, two sets of inclined shovel components are respectively fixedly connected to the two long ends of the cross, two sets of L-shaped rods are respectively rotatably connected to the two short ends of the cross, and the mixing shovel is fixedly connected to the lower end of the L-shaped rod.

[0006] Preferably, the power assembly includes a stepper motor, a coupling, a central shaft, and a chain and sprocket assembly. Two sets of chain and sprocket assemblies are sequentially connected to the middle of the central shaft, and the middle of the other sprocket of the chain and sprocket assembly is fixedly connected to the upper end of the L-shaped rod.

[0008] Preferably, one side of the extension and the lower end of the inclined shovel are both attached to the inner wall of the mixing tank.

[0009] Preferably, the feeding mechanism includes an electric cylinder, a column, a sector plate, a connecting column, and a side rail, with the sector plate movably connected to the lower opening of the mixing tank.

[0010] Preferably, the sector plate is slidably connected to the inner wall of the side rail, the column is fixedly connected to one side of the sector plate, the upper end of the column is rotatably connected to the movable rod of the electric cylinder, and the end of the electric cylinder is rotatably connected to the outside of the mixing tank.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the central shaft is driven by the power component to rotate the cross.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a batching mechanism for premixed mortar processing, including a mixing tank 1 and a conical cover 2. The upper side of the conical cover 2 is provided with an inlet pipe 3 for adding cement and sand and a tilting plate 5 for adding water. A mixing mechanism 4 is fixedly installed in the middle of the conical cover 2, extending into the inner cavity of the mixing tank 1. A feeding mechanism 6 is provided at the lower opening of the mixing tank 1. The mixing mechanism 4 includes a power assembly, a cross 44, extension parts 45, inclined shovel parts 46, L-shaped rods 47, and a mixing shovel 48. Four sets of extension parts 45 are fixedly connected to the four ends of the cross 44, two sets of inclined shovel parts 46 are respectively fixedly connected to the two long ends of the cross 44, and two sets of L-shaped rods 47 are respectively rotatably connected to the two ends of the cross 44. The short end of the stirring shovel 48 is fixedly connected to the lower end of the L-shaped rod 47. The power assembly includes a stepper motor 41, a coupling 42, a central shaft 43, and a chain and sprocket assembly 49. Two sets of chain and sprocket assemblies 49 are sequentially connected to the middle of the central shaft 43. The middle of the other sprocket of the chain and sprocket assembly 49 is fixedly connected to the upper end of the L-shaped rod 47. The central shaft 43 is rotatably mounted in the middle of the conical cover 2 through bearings. The upper end of the central shaft 43 is fixedly connected to the output shaft of the stepper motor 41 through the coupling 42. The lower end of the central shaft 43 is fixedly connected to the middle of the cross 44. The stepper motor 41 is fixedly mounted on the upper side of the conical cover 2. One side of the extension 45 and the lower end of the inclined shovel 46 are both attached to the inner wall of the mixing tank 1.

[0023] The specific setup and function of this embodiment are described below: Cement and sand are fed into the mixing tank 1 through two sets of feed pipes 3, while water and admixtures are added by opening the tilting plate 5. This allows each component to be metered and fed separately, avoiding interference between them. Then, the stepper motor 41 is started. The output shaft of the stepper motor 41 drives the central shaft 43 to rotate through the coupling 42. The central shaft 43 rotates at the center of the conical cover 2 with the help of bearings, driving the cross 44 to rotate. The two sets of inclined shovels 46 connected to its two long ends respectively conform to the inner bottom wall and inner side wall of the mixing tank 1 and make circular motion. The lower shovel of the inclined shovel 46 first mixes the components, while the central shaft 43 drives the cross 44 to rotate. The rotation of the two large sprockets causes the cross 44 to drive the L-shaped rod 47 and the small sprocket fixed on its upper part to move in a circular motion. Since the linear velocity of the large sprockets and the linear velocity of the small sprockets' circular revolution are different, the chain will move between the two sprockets, thereby driving the small sprockets to rotate. This causes the two sets of L-shaped rods 47 to rotate at the two short ends of the cross 44 respectively. The two sets of chain and sprocket assemblies 49 realize the circular motion of the two sets of stirring shovels 48. When the two sets of stirring shovels 48 stir together, they enhance the irregular movement and shearing action of the fluid, and further improve the mixing effect through turbulence. This avoids the insufficient diffusion of small doses of additives, and also shortens the mixing cycle and improves the quality of the ingredients.

[0024] Example 2: Figure 1 - Figure 4 As shown, the feeding mechanism 6 includes an electric cylinder 61, a column 62, a sector plate 63, a connecting column 64, and a side rail 65. The sector plate 63 is movably connected to the lower opening of the mixing tank 1, and the sector plate 63 is slidably connected to the inner wall of the side rail 65. The column 62 is fixedly connected to one side of the sector plate 63. The upper end of the column 62 is rotatably connected to the movable rod of the electric cylinder 61. The end of the electric cylinder 61 is rotatably connected to the outside of the mixing tank 1. The connecting column 64 is rotatably connected to the outside of the mixing tank 1, and the lower end of the connecting column 64 is rotatably connected to the corner of the sector plate 63.

[0025] The overall effect of this embodiment is that, at the end of the mixing process, the movable rod of the electric cylinder 61 extends, pushing the column 62. The column 62 is located at the middle of the edge of the sector plate 63, applying torque to the sector plate 63, causing the sector plate 63 to move in an arc around the connection point with the connecting column 64 on the inner wall of the side rail 65, and move away from the lower opening of the mixing tank 1, so that the premixed mortar inside can be transferred out for use, which is convenient for personnel operation, saves manpower, and optimizes the construction process.

[0026] The operating method and working principle of this device are as follows: Cement and sand are fed into the mixing tank 1 through two sets of feed pipes 3, while water and admixtures are added by opening the tilting plate 5. Then, the stepper motor 41 is started. The output shaft of the stepper motor 41 drives the central shaft 43 to rotate via the coupling 42, which in turn drives the cross 44 to rotate. The two sets of inclined shovels 46, connected to their long ends, move in a circular motion against the inner bottom and inner side walls of the mixing tank 1. The lower shovel of the inclined shovel 46 first mixes the components. Simultaneously, the central shaft 43 drives two large sprockets to rotate, and the cross 44 drives the L-shaped rod 47 and its upper fixed small sprocket to move in a circular motion. Due to the large... The linear velocity of the sprocket is different from the linear velocity of the small sprocket's circumferential revolution. The chain drives the small sprocket to rotate, which in turn drives the two sets of L-shaped rods 47 to rotate at the two short ends of the cross 44, thus enabling the two sets of mixing shovels 48 to make circular motion. When the two sets of mixing shovels 48 work together, the mixing effect is further improved through turbulence, avoiding insufficient diffusion of small doses of additives. At the end of the mixing process, the movable rod of the electric cylinder 61 is extended, pushing the column 62 to apply torque to the sector plate 63, causing the sector plate 63 to move in an arc around the connection point with the connecting column 64 on the inner wall of the side rail 65, and move away from the lower opening of the mixing tank 1, transferring the premixed mortar inside for use.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
