Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cement mixing device with a precise feeding function for building engineering construction. Background Technique

[0002] Building construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, and decoration engineering construction, etc. The place where construction operations are carried out is called the "building construction site" or "construction site". When mixing cement, a corresponding cement mixing device will be used.

[0003] The utility model with the existing authorization publication number CN220638431U discloses a cement mixing device for building engineering construction, including a vertical plate. A vertical groove is opened on the side surface of the vertical plate. An L-shaped support plate is slidably connected inside the vertical groove. A first motor is fixedly installed on the surface of the L-shaped support plate. The output end of the first motor is fixedly installed with a gear. A rack is fixedly installed on the surface of the vertical plate. Two connecting rods are fixedly installed on the surface of the L-shaped support plate away from the first motor. The two connecting rods are fixedly installed with a support plate at the end away from the L-shaped support plate. A sealing cover is fixedly installed at the end of the support plate away from the connecting rod.

[0004] Adopting the above technical solution, by setting a hydraulic rod, the driving plate further controls the top plate to move up and down to block the mixing barrel, avoiding the reduction of splash loss of cement during mixing. At the same time, after mixing, it controls the top plate to drive the mixing rod to rise and provide power for the discharging mechanism. However, when the above technical solution is used, it does not have a precise feeding function and can only rely on the feeling of workers to mix different materials in a suitable proportion. Therefore, the prepared cement is very likely to have a reduced stability or even insufficient strength due to inaccurate proportion input, which will not only cause waste of resources but also lead to the problem of extended construction period.

[0005] Therefore, the technical personnel in this field provide a cement mixing device with a precise feeding function for building engineering construction to solve the problems raised in the above background technique. Content of the Utility Model

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

Detailed implementation mode

[0022] Please refer to Figures 1-4 , a cement mixing device with precise feeding function for construction engineering construction, including a mixing drum 1, a weighing device 3 and a tipping device 2 are respectively installed on the outer side of the mixing drum 1. The tipping device 2 includes two fixed plates 202, and the inner walls of each fixed plate 202 are fixedly connected to the outer surface of the mixing drum 1. The upper surface of one of the fixed plates 202 is fixedly connected with a first stepping motor 201. The inner part of the mixing drum 1 is clamped with a top plate 9. A rectangular groove 8 is opened on the upper surface of the top plate 9. The upper surface of the top plate 9 is fixedly connected with a handle 7. By setting the top plate 9, it can be ensured that no sundries enter the inside of the mixing drum 1 when the mixing drum 1 is not in use, and the handle 7 can provide a suitable force-bearing position for the top plate 9 to facilitate the extraction of the top plate 9.

[0023] The upper surface of the other fixed plate 202 is fixedly connected with a fixed block 203. The output end of the first stepping motor 201 is fixedly connected with a rotating shaft 204. The bottom surface of the mixing drum 1 is fixedly connected with three support legs 6. The outer surfaces of the three support legs 6 are jointly fixedly connected with a bottom plate 5. The upper surface of the bottom plate 5 is fixedly connected with a fixed seat 10. The inner wall of the fixed seat 10 is fixedly connected with a second stepping motor 11. By setting the support legs 6, the support legs 6 can provide support force for the device, making the device away from the ground, facilitating unloading, and the bottom plate 5 can increase the contact area between the device and the ground, making the device stand more stably and providing a support position for the fixed seat 10 and the second stepping motor 11.

[0024] The outer surface of the rotating shaft 204 is rotationally connected to the inner wall of the fixed block 203. The outer surface of the rotating shaft 204 is fixedly connected with a connecting plate 205. The back surface of the connecting plate 205 is fixedly connected with two rectangular frames 206. The output end of the second stepping motor 11 is fixedly connected with a rotating shaft 14. The outer surface of the rotating shaft 14 is rotationally connected to the inner wall of the mixing drum 1. The outer surface of the rotating shaft 14 is fixedly connected with two groups of mixing rods 15. Through the rotating shaft 14, the power generated when the second stepping motor 11 operates can be transmitted to the mixing rods 15, and thus the raw materials can be stirred by the mixing rods 15.

[0025] A first telescopic rod 207 is fixedly connected to the inner wall of each rectangular frame 206. A limiting block 208 is fixedly connected to the telescopic end of each first telescopic rod 207. One end of the two limiting blocks 208 close to each other penetrates through the rectangular frame 206 and extends to the outside of the rectangular frame 206. The weighing device 3 includes a rectangular box 301. A weight sensor 302 is fixedly connected to the inner bottom wall of the rectangular box 301. A placing frame 303 is arranged inside the rectangular box 301. The bottom surface of the placing frame 303 is in contact with the sensing end of the weight sensor 302. The outer surface of the placing frame 303 is in contact with the inner wall of the rectangular box 301. A baffle 13 is clamped inside the mixing drum 1. A pulling handle 12 is fixedly connected to the bottom surface of the baffle 13. By providing the pulling handle 12 and the baffle 13, the baffle 13 can be opened by pulling the pulling handle 12, so that the cement stirred in the mixing drum 1 can be unloaded.

[0026] Two limiting grooves 304 are opened on both sides of the rectangular box 301. The outer surface of the limiting block 208 is clamped inside each limiting groove 304. Two second telescopic rods 4 are fixedly connected to the upper surface of the bottom plate 5. A push plate 17 is fixedly connected to the telescopic end of each second telescopic rod 4. Force-bearing plates 16 are fixedly connected to both sides of the rectangular box 301. The bottom surface of each force-bearing plate 16 is in contact with the upper surface of the push plate 17. The push plate 17 can be pushed by the second telescopic rod 4, so as to provide a supporting force for the force-bearing plate 16 and facilitate driving the rectangular box 301 to move up or down.

[0027] The working principle of the present utility model is as follows: When in use, first, the first stepping motor 201, the second stepping motor 11, the first telescopic rod 207, the second telescopic rod 4, and the weight sensor 302 are respectively powered on. After the power is connected, the device can be used normally. When the device needs to be used, only need to control the first telescopic rod 207 to contract, so that the limiting block 208 is disengaged from the clamping relationship with the limiting groove 304. At this time, the entire weight of the rectangular box 301 acts on the force-bearing plate 16 and the push plate 17. Then control the second telescopic rod 4 to contract, so that the rectangular box 301 contacts the bottom plate 5. Then put the material to be stirred into the interior of the placement frame 303. When the material enters the interior of the placement frame 303, the weight sensor 302 will weigh the placement frame 303 and the material inside the placement frame 303. Therefore, subtracting the weight of the placement frame 303 from the total weight can obtain the weight of the material. Subsequently, reverse the operation of the second telescopic rod 4 to push the rectangular box 301 to move upward. When the rectangular box 301 moves to a suitable position, control the two first telescopic rods 207 to operate, so that the limiting block 208 passes through the rectangular frame 206 and is clamped inside the limiting groove 304. Then pull out the top plate 9 through the handle 7. At the same time, control the first stepping motor 201 to operate. The operation of the first stepping motor 201 can drive the rotating shaft 204 to rotate. And a connecting plate 205 is fixed on the outer surface of the rotating shaft 204. The back surface of the connecting plate 205 is fixed to the front surfaces of the two rectangular frames 206. And at this time, the limiting block 208 is located between the rectangular frame 206 and the rectangular box 301. Therefore, through a series of force transmissions, the rotational power generated when the first stepping motor 201 operates can be transmitted to the rectangular box 301, so as to drive the rectangular box 301 to rotate around the rotating shaft 204, so that the materials placed inside the placement frame 303 can be poured into the interior of the stirring device. Repeat the above steps to put all the materials to be stirred into the interior of the stirring barrel 1 to carry out stirring, thus effectively avoiding the situation that when the device is in use, it can only rely on the intuition of workers to decide how much material to put in for stirring, resulting in a large error. Seriously, it may lead to problems such as low cement strength and extended construction period.

[0028] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
