Description

Technical Field

[0001] This utility model relates to the field of municipal civil engineering technology, and more specifically, to a municipal civil engineering construction pouring device. Background Technology

[0002] Concrete, an indispensable material in modern construction and municipal engineering, directly affects the overall quality and safety of the project. Traditional concrete preparation and pouring methods typically rely on large mixing plants and pump trucks for long-distance transportation and pouring. However, in municipal civil engineering construction, especially in complex terrain and confined spaces, large equipment often struggles to access the site, leading to low construction efficiency and even the inability to complete the pouring task. Furthermore, the quality of the concrete slurry can be affected during prolonged transportation and waiting, resulting in phenomena such as segregation and layering, thus impacting its final mechanical properties and service life.

[0003] To address the aforementioned issues, miniaturized and intelligent concrete preparation and pouring equipment has become a research hotspot in recent years. These devices not only possess advantages such as small size, high flexibility, and ease of transportation and installation, but also enable on-site concrete preparation and pouring, significantly improving construction efficiency and concrete quality. However, current small-scale concrete preparation and pouring equipment still suffers from some shortcomings, such as uneven raw material mixing, low material feeding accuracy, and unsatisfactory mixing effects. These problems directly impact the performance and application of concrete. Therefore, this paper proposes a municipal civil engineering construction pouring device to address these issues. Utility Model Content

This solution, through the setting of a feeding box and feeding components, can quantitatively add multiple raw materials in batches into a mixing tank for stirring and mixing. It can better control the amount of multiple raw materials added and the mixing time, thereby achieving more uniform mixing. The feeding components can also control the interval time of feeding, thereby better controlling the rate and extent of the raw material reaction, so that each batch of raw materials has sufficient time to mix into a high-quality slurry, thereby improving the on-site pouring quality.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) Through the design of the feeding component, multiple raw materials can be added in batches and in quantitative quantities. Users can put multiple raw materials into multiple feeding troughs, and then, through the precise control of the feeding component, the raw materials are put into the mixing bucket according to the preset ratio and time interval. This method not only improves the mixing accuracy of the raw materials, but also ensures the uniformity of the mixture, thereby improving the quality of concrete.

[0017] (2) The mixing tank is equipped with multiple mixing rollers, which can achieve efficient mixing through the drive of the first servo motor.

[0037] Example:

[0038] Please see Figure 1-2 A municipal civil engineering construction pouring device includes a mixing tank 1 and a support 6. A first servo motor 2 is installed at the top of the mixing tank 1, and a feeding pipe 3 connected to the inner cavity is fixedly connected to the bottom of the mixing tank 1. A rotating shaft 4 is provided in the inner cavity of the mixing tank 1. The bottom end of the rotating shaft 4 is rotatably connected to the inner wall of the mixing tank 1. The output end of the first servo motor 2 extends to the inner cavity of the mixing tank 1 and is fixedly connected to the top of the rotating shaft 4. Multiple stirring rollers 5 are fixedly connected to the outer end of the rotating shaft 4. A feeding box 7 is installed on the support 6. Multiple feeding slots 8 are opened on the feeding box 7, and a feeding component 9 is provided on the side of the feeding box 7 near the mixing tank 1.

[0039] Concrete slurry used for on-site pouring is pre-mixed according to a certain ratio and then transported to the civil construction site for pouring. However, in some working conditions, it is difficult for transport vehicles or pump trucks to enter, so small equipment is needed to assist in pouring or even manual transportation and pouring. This is not only inefficient but also reduces the quality of concrete slurry. In this solution, the user can put multiple raw materials into multiple feeding troughs 8, and then use the feeding component 9 to quantitatively feed the raw materials from the multiple feeding troughs 8 into the inner cavity of the mixing tank 1 in batches. After the raw materials enter the inner cavity of the mixing tank 1, the user starts the first servo motor 2 to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives multiple mixing rollers 5 to move, which can stir the raw materials in the mixing tank 1, thereby mixing the multiple raw materials. After mixing, the concrete slurry can be discharged through the discharge pipe 3 for pouring. With this setting, since the multiple raw materials are added to the mixing tank 1 at the same time each time, the amount of multiple raw materials added and the mixing time can be better controlled, thereby achieving more uniform mixing. Each batch of raw materials will be fully mixed in the continuously running mixing rollers 5, which helps to ensure the uniform distribution of raw materials.

[0040] Various raw materials, including aggregates, cement, water, admixtures, and other components, are prepared according to the standards of the construction site.

[0041] Please see Figure 3 The outer end of the feeding box 7 is provided with multiple observation ports 10, which are connected to multiple feeding troughs 8 respectively. The inner wall of the observation port 10 is equipped with a matching transparent plate, and the outer surface of the transparent plate is engraved with scale lines.

[0042] With the transparent plate and scale lines, users can more easily observe the amount of raw materials added when putting them into the feed trough 8, thereby better controlling the ratio of each raw material.

[0043] Please see Figure 4-5The feeding assembly 9 includes a feeding box 901, one end of which is fixedly connected to the feeding box 7. The end of the feeding box 901 away from the feeding box 7 penetrates the side wall of the mixing tank 1 and extends into the inner cavity of the feeding box 7. The feeding box 901 is fixedly connected to the mixing tank 1. The feeding box 901 has multiple feeding slots 902, which are respectively connected to multiple feeding slots 8. The feeding slots 8 are connected to the inner cavity of the mixing tank 1 through the feeding slots 902. The feeding assembly 9 also includes a connecting rod 905, which penetrates the feeding box. The side wall of 901 is rotatably connected to the feeding box 901. The connecting rod 905 extends into the inner cavity of the multiple feeding slots 902. A second servo motor 903 is installed at the outer end of the feeding box 901. The output end of the second servo motor 903 passes through the side wall of the feeding box 901 and is fixedly connected to the connecting rod 905. The inner cavity of the multiple feeding slots 902 is provided with a rotating block 904 that matches the inner cavity. The multiple rotating blocks 904 are integrally formed with the connecting rod 905, and a pair of mutually symmetrical metering slots 906 are opened at the outer end of the rotating block 904.

[0044] After the user puts various raw materials into the multiple feeding troughs 8, the user can start the second servo motor 903 to drive the connecting rod 905 to rotate. In turn, the connecting rod 905 drives multiple rotating blocks 904 to rotate synchronously in the inner cavities of multiple feeding troughs 902. During the rotation of the rotating blocks 904, when a certain metering trough 906 rotates to connect with the inner cavity of the feeding trough 8, the raw materials in the feeding trough 8 will fall into the metering trough 906. Then, when the metering trough 906 containing raw materials rotates to connect with the feeding trough 902, the raw materials in it will fall into the inner cavity of the mixing tank 1 through the feeding trough 902. This setting can ensure that the raw materials are added in batches, and at the same time, the amount of each raw material added each time is consistent. At the same time, by adjusting the speed of the second servo motor 903, the interval time of feeding can be controlled, thereby better controlling the rate and degree of reaction of the raw materials, so that each batch of raw materials has sufficient time to mix into a high-quality slurry, thereby improving the on-site pouring quality.

[0045] Working principle:

[0046] In use, the user can put various raw materials into multiple feeding troughs 8, then start the second servo motor 903 to drive the connecting rod 905 to rotate. The connecting rod 905 then drives multiple rotating blocks 904 to rotate synchronously within the cavities of multiple feeding troughs 902. During the rotation of the rotating blocks 904, when a metering trough 906 rotates to connect with the cavity of the feeding trough 8, the raw materials in the feeding trough 8 will fall into the metering trough 906. Then, when the metering trough 906 containing raw materials rotates to connect with the feeding trough 902, the raw materials will fall into the cavity of the mixing tank 1 through the feeding trough 902, thus merging the multiple feeding troughs... The raw materials in 8 are quantitatively added to the inner cavity of the mixing tank 1 in batches. After the raw materials enter the inner cavity of the mixing tank 1, the user starts the first servo motor 2 to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives multiple mixing rollers 5 to move, which can stir the raw materials in the mixing tank 1, thereby mixing multiple raw materials. After mixing, the concrete slurry can be discharged through the discharge pipe 3 for pouring. If necessary, a hose can be connected to the discharge pipe 3 for extension, or the discharge pipe 3 can directly adopt a long hose structure. This device can be used with a small transport vehicle or a basket, and can be used for targeted pouring in some difficult areas of the civil construction site.

[0047] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
