Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a filler mixing device for construction engineering. Background Technology

[0002] In construction engineering, concrete mixing is a fundamental and crucial process, and its efficiency and quality directly affect the project's progress and structural performance. Traditional concrete mixing plants mostly employ a single mixing drum structure, mechanically mixing cement, aggregates, and water through internal spiral blades or a mixing shaft. However, such equipment has significant limitations in practical applications: First, after mixing, the entire batch of concrete must be completely unloaded before the next batch of raw materials can be added, resulting in intermittent stoppages in the production process and making continuous operation difficult; second, due to the lack of segmented storage and quantitative output mechanisms, unloading often requires tilting the entire mixing drum or discharging through a single outlet, easily causing concrete to accumulate on the construction site, occupying limited working space and increasing the cost of secondary material transfer. Therefore, further improvements are needed. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a filler mixing device for construction engineering.

[0004] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a filling mixing device for construction engineering, including: a frame, a mixing chamber, a mixing component, a storage silo and a discharge component;

[0005] The mixing chamber is mounted above the frame, with an opening at the top. The mixing assembly is mounted on the mixing chamber for mixing concrete. The storage silo is mounted on the frame, above the mixing chamber. The mixing chamber has a discharge port equipped with an on / off valve assembly. The concrete from the mixing chamber can fall into and be collected in the storage silo.

[0006] The unloading assembly includes an unloading channel and an unloading screw; the unloading channel is inclined; the lower part of the unloading channel is connected to the lower part of the storage silo, and an unloading port is opened at the upper part of the unloading channel; the unloading screw is disposed in the unloading channel and is used to transport the concrete in the storage silo to the unloading port.

[0007] Optionally, the on / off valve assembly is a sealing plate that is laterally slidably inserted into the material discharge port; the sealing plate can move laterally to open or close the material discharge port.

[0008] Optionally, a push-pull handle is provided on one side of the sealing plate.

[0009] Optionally, the storage bin is configured as an inverted cone or inverted pyramid shape; the lower part of the unloading channel is connected to the bottom of the storage bin.

[0010] Optionally, the stirring assembly includes a stirring rod and a stirring propeller; the stirring rod is rotatably inserted through the stirring chamber and connected to a stirring motor; the stirring propeller is fixed to the stirring rod and has a spiral ring around the outer periphery of the stirring rod.

[0011] Optionally, two stirring propellers are provided, with different diameters, and are coaxially spirally arranged on the outer periphery of the stirring rod.

[0012] Optionally, the discharge port is inclined downwards.

[0013] The beneficial effects of this utility model are as follows: This application significantly improves the efficiency of concrete mixing and supply by adopting a separate structural design for the mixing silo and storage silo, combined with the coordinated operation of the unloading components. After the mixing silo completes the concrete mixing, the finished material can be temporarily stored in the storage silo through the on / off valve assembly, and then the next batch of mixing can be started immediately, realizing the parallel operation of mixing and storage. This breaks through the intermittent production bottleneck of the traditional single-bucket structure and greatly shortens the operation cycle. The inclined unloading channel works in conjunction with the unloading screw, using the screw's rotation speed and stroke to precisely control the concrete output, avoiding material accumulation on the construction site, meeting the quantitative requirements of different pouring scenarios, and reducing material waste. The storage silo, as a temporary storage unit, reduces the waiting time for unloading from the mixing silo, avoids direct concrete piling on the site, saves construction space, and reduces secondary transfer costs.

[0024] Example

[0025] Reference Figure 1 and Figure 2 The present invention proposes a filling mixing device for construction engineering, comprising: a frame 10, a mixing chamber 20, a mixing component 30, a storage chamber 40, and a discharge component 50;

[0026] The mixing chamber 20 is mounted above the frame 10, with an opening at the top. The mixing assembly 30 is mounted on the mixing chamber 20 for mixing concrete. The storage silo 40 is mounted on the frame 10, located above the mixing chamber 20. The mixing chamber 20 is equipped with a discharge port 21, which is fitted with an on / off valve assembly 22. The concrete from the mixing chamber 20 can fall and be collected in the storage silo 40.

[0027] The unloading assembly 50 includes an unloading channel 51 and an unloading screw 52; the unloading channel 51 is inclined; the lower part of the unloading channel 51 is connected to the lower part of the storage bin 40, and an unloading port 53 is opened at the upper part of the unloading channel 51; the unloading screw 52 is disposed in the unloading channel 51 and is used to transport the concrete in the storage bin 40 to the unloading port 53.

[0028] In this invention, the separate structural design of the mixing chamber 20 and the storage chamber 40, combined with the coordinated operation of the unloading component 50, significantly improves the efficiency of concrete mixing and supply. After the mixing chamber 20 completes concrete mixing, the finished material can be temporarily stored in the storage chamber 40 through the on / off valve component 22, and then the next batch of mixing can be started, realizing parallel operation of mixing and storage, breaking through the intermittent production bottleneck of the traditional single-bucket structure, and greatly shortening the operation cycle. The inclined unloading channel 51 works in conjunction with the unloading screw 52 to precisely control the concrete output by utilizing the screw's rotation speed and stroke, avoiding material accumulation on the construction site, meeting the quantitative requirements of different pouring scenarios, and reducing material waste. The storage chamber 40, as a temporary storage unit, reduces the unloading waiting time of the mixing chamber 20, avoids direct concrete piling on the site, saves construction space, and reduces secondary transfer costs.

[0029] In this embodiment, the on / off valve assembly 22 is a sealing plate 221 that is laterally slidably inserted into the material discharge port 21. The sealing plate 221 can move laterally to open or close the material discharge port 21. Compared with traditional flap valves or butterfly valves, the sealing plate 221 has a shorter stroke and lower resistance, which can quickly complete the on / off operation and reduce the risk of material jamming. The tight fit design between the lateral sealing surface and the edge of the material discharge port 21 effectively prevents concrete leakage and ensures the stability of the materials temporarily stored in the storage silo 40.

[0030] Furthermore, to facilitate the operation of the movable sealing plate 221, a push-pull handle 222 is provided on one side of the sealing plate 221.

[0031] In this embodiment, the storage silo 40 is configured as an inverted cone or inverted pyramidal structure; the lower part of the unloading channel 51 is connected to the bottom of the storage silo 40. The inverted cone structure utilizes the self-weight of the concrete to achieve concentrated flow to the bottom unloading channel 51, avoiding the accumulation of materials in the silo due to structural dead corners. The low coefficient of sliding friction between the cone-shaped wall and the material, combined with the forced conveying of the unloading screw 52, ​​ensures that there is no residue in the storage silo 40, achieving efficient silo cleaning.

[0032] In this embodiment, the mixing assembly 30 includes a mixing rod 31 and a mixing propeller 32. The mixing rod 31 is rotatably inserted into the mixing chamber 20 and connected to the mixing motor. The mixing propeller 32 is fixed to the mixing rod 31, and its spiral ring is disposed on the outer periphery of the mixing rod 31. When the spiral blades of the mixing propeller 32 rotate, they form a combined axial and radial motion, which pushes the material to roll up and down and diffuse radially, eliminating the stratification of cement and aggregate and ensuring the uniformity of concrete mixing.

[0033] Specifically, two agitator propellers 32 are provided, with different diameters, and are coaxially spirally arranged on the outer periphery of the agitator rod 31. The twin spiral propellers with different diameters create differentiated shear force fields within the mixing chamber 20. The larger diameter propeller dominates the macroscopic material circulation, while the smaller diameter propeller enhances local eddy current disturbance. The two work together to break up aggregate agglomeration, significantly improving the coating effect between fine aggregates and cement paste, and preventing segregation.

[0034] In this embodiment, the discharge port 53 is inclined downwards. The inclined downward design of the discharge port 53 allows the concrete to be discharged in a directional flow, reducing dust from the discharge port 53. At the same time, by adjusting the tilt angle to match the interface position of the transport vehicle or pouring pipe, material spillage is avoided, reducing environmental pollution and cleanup costs.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
