Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of concrete mixer trucks, and particularly relates to a low-slump concrete mixer truck. Background Technology
[0002] Low-slump concrete is suitable for projects requiring high strength and durability, characterized by its poor flowability and strong cohesiveness. Due to its poor fluidity, low-slump concrete requires special care during transportation to ensure concrete quality and construction efficiency.
[0003] In existing technologies, the loading troughs of concrete mixer trucks have a large curvature, which is unfavorable for loading low-slump concrete. Low-slump concrete is generally transported by flatbed trucks, but flatbed truck transportation is inefficient and consumes a lot of manpower. Furthermore, as... Figure 1 As shown, the radius of the existing connecting ring 7 between the feed inlet and the mixing drum of the existing concrete mixer truck is generally around 35cm. The small radius of the existing connecting ring makes it easy to cause blockage when loading low slump concrete, resulting in low loading efficiency. The tilt angle α of the existing unloading chute 8 relative to the ground is generally around 10°. The small tilt angle causes the unloading speed of low slump concrete to be too slow, which can easily lead to accumulation and blockage or even mixing. This increases the difficulty of on-site maintenance work.
[0004] Therefore, how to solve the problem that current concrete mixer trucks are not suitable for transporting low-slump concrete is a technical problem that urgently needs to be solved. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a low-slump concrete mixer truck. By setting up a guide plate, it can effectively guide low-slump concrete into the mixing drum, reduce the phenomenon of material blockage, and avoid the problem of low loading efficiency caused by poor fluidity.
[0006] This utility model provides a low-slump concrete mixer truck, comprising:
[0007] A stirring drum with two openings at one end;
[0008] The loading port, which is installed at one of the openings of the mixing drum, is used to load low-slump concrete into the mixing drum.
[0009] A guide plate, installed inside the loading port and extending into the mixing drum, is used to guide the flow of low-slump concrete.
[0010] This technical solution can effectively guide low-slump concrete into the mixing drum, reducing material blockage.
[0011] In some embodiments, the guide plate is a straight plate with a slope greater than the curvature of the loading port. This technical solution can more effectively guide low-slump concrete into the mixing drum, reduce the resistance of the concrete during the loading process, and avoid blockage.
[0012] In some embodiments, the guide plate is welded to the loading port. This technical solution enhances the stability and durability of the structure, preventing the guide plate from loosening or falling off due to vibration or concrete impact.
[0013] In some embodiments, a connecting ring is provided between the mixing drum and the charging port, the connecting ring being fitted onto the opening of the mixing drum, and a guide plate passing through the connecting ring. This technical solution makes the connection between the mixing drum and the charging port tighter, and the guide plate passing through the connecting ring further optimizes the flow path of the concrete.
[0014] In some embodiments, the diameter of the connecting ring is not less than 45 cm. This technical solution significantly expands the loading channel, allowing low-slump concrete to enter the mixing drum more smoothly and improving loading efficiency.
[0015] In some embodiments, a discharge port is installed at another opening of the mixing drum for unloading low-slump concrete. This technical solution allows low-slump concrete to be smoothly unloaded from the other opening of the mixing drum, avoiding the unloading difficulties caused by the poor fluidity of concrete in traditional unloading methods.
[0016] In some embodiments, the discharge port is connected to a discharge chute, which guides the unloading of low-slump concrete. This technical solution further optimizes the concrete unloading path, guiding the concrete to flow smoothly out of the discharge port and reducing blockages and accumulation during the unloading process.
[0017] In some embodiments, the angle between the unloading chute and the ground is not less than 35°. This technical solution significantly improves the unloading speed of low-slump concrete, avoids the problems of slow concrete flow and accumulation caused by too small an inclination angle, and improves unloading efficiency.
[0018] In some embodiments, the low-slump concrete mixer truck also includes a vehicle body, with a mixing drum mounted on the vehicle body, and one end of the mixing drum's opening being away from the driver's cab. This technical solution makes loading and unloading operations more convenient, while reducing interference to the driver's cab during concrete unloading, thus improving operational safety and construction efficiency.
[0019] Based on the above solution, the low-slump concrete mixer truck in this embodiment of the invention, through the setting of the guide plate, can effectively guide low-slump concrete into the mixing drum, reduce the phenomenon of material blockage, and avoid the problem of low loading efficiency caused by poor fluidity. Compared with flatbed truck transportation, this embodiment uses a low-slump concrete mixer truck for transportation, which can realize continuous transportation and unloading of concrete, reduce interruptions and waiting time during transportation, and significantly improve construction efficiency; moreover, the mixer truck can continuously mix concrete during transportation, preventing low-slump concrete from stratification or initial setting due to poor fluidity, ensuring the uniformity and quality of concrete; the mixer truck realizes mechanized operation of loading, transportation and unloading, reducing the need for manual handling and operation, and reducing labor costs and labor intensity.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] like Figures 2-3 As shown, in one embodiment of the low-slump concrete mixer truck of this utility model, the low-slump concrete mixer truck includes a mixing drum 1, a loading port 2, and a guide plate 4; wherein, the mixing drum 1 has two openings at one end; the loading port 2 is installed at one of the openings of the mixing drum 1 for loading low-slump concrete into the mixing drum 1; the guide plate 4 is installed inside the loading port 2 and extends into the mixing drum 1 for guiding the flow of low-slump concrete.
[0030] In the above illustrative embodiment, the low-slump concrete mixer truck, through the setting of the guide plate 4, can effectively guide the low-slump concrete into the mixing drum 1, reducing the phenomenon of material blockage and avoiding the problem of low loading efficiency caused by poor fluidity. Compared with flatbed truck transportation, this embodiment uses a low-slump concrete mixer truck for transportation, which can realize continuous transportation and unloading of concrete, reduce interruptions and waiting time during transportation, and significantly improve construction efficiency; moreover, the mixer truck can continuously mix concrete during transportation, preventing the low-slump concrete from stratifying or prematurely setting due to poor fluidity, ensuring the uniformity and quality of concrete; the mixer truck realizes the mechanization of loading, transportation and unloading operations, reducing the need for manual handling and operation, and reducing labor costs and labor intensity.
[0031] In some embodiments, such as Figure 3As shown, the guide plate 4 is a straight plate with a slope greater than the curvature of the loading port 2. By designing the guide plate 4 as a straight plate with a slope greater than the curvature of the loading port 2, low-slump concrete can be guided into the mixing drum 1 more effectively, reducing the resistance of the concrete during the loading process, avoiding blockage, and thus improving loading efficiency.
[0032] Furthermore, the guide plate 4 is welded to the loading port 2. The guide plate 4 and the loading port 2 are fixed by welding, which enhances the stability and durability of the structure, prevents the guide plate 4 from loosening or falling off due to vibration or concrete impact, and ensures the continuity and reliability of the loading process.
[0033] In some embodiments, such as Figure 3 As shown, a connecting ring 3 is provided between the mixing drum 1 and the loading port 2. The connecting ring 3 is fitted onto the opening of the mixing drum 1, and the guide plate 4 passes through the connecting ring 3. The design of the connecting ring 3 makes the connection between the mixing drum 1 and the loading port 2 tighter, and the guide plate 4 passing through the connecting ring 3 further optimizes the flow path of the concrete, reducing the accumulation and blockage of concrete during the loading process.
[0034] In some embodiments, the diameter of the connecting ring 3 is not less than 45 cm. Compared to the smaller diameter of the connecting ring 3 in the prior art (around 35 cm), the diameter of the connecting ring 3 of not less than 45 cm significantly expands the loading channel, allowing low-slump concrete to enter the mixing drum 1 more smoothly and improving loading efficiency.
[0035] In some embodiments, such as Figure 2 As shown, a discharge port 5 is installed at the other opening of the mixing drum 1. The discharge port 5 is used for unloading low-slump concrete. The design of the discharge port 5 allows low-slump concrete to be smoothly unloaded from the other opening of the mixing drum 1, avoiding the problem of unloading difficulties caused by the poor fluidity of concrete in traditional unloading methods.
[0036] In some embodiments, such as Figure 2 As shown, the discharge port 5 is connected to the discharge chute 6, which is used to guide the unloading of low-slump concrete. The installation of the discharge chute 6 further optimizes the unloading path of the concrete, guiding the concrete to flow smoothly out of the discharge port 5 and reducing blockages and accumulation during the unloading process.
[0037] In some embodiments, the angle between the unloading chute 6 and the ground is not less than 35°. As an illustrative embodiment, such as... Figure 2 As shown, the angle β between the unloading chute 6 and the ground is 37°. By increasing the angle between the unloading chute 6 and the ground to not less than 35° (such as 37°), the unloading speed of low slump concrete is significantly improved, avoiding the problems of slow concrete flow and accumulation caused by too small an angle, and improving unloading efficiency.
[0038] In some embodiments, the low-slump concrete mixer truck also includes a vehicle body (not shown in the figure), with the mixing drum 1 mounted on the vehicle body. One end of the opening of the mixing drum 1 is away from the driver's cab of the vehicle body. The design of the opening of the mixing drum 1 being away from the driver's cab makes loading and unloading operations more convenient, while reducing interference to the driver's cab during concrete unloading, thereby improving operational safety and construction efficiency.
[0039] Through the description of several embodiments of the low-slump concrete mixer truck of this utility model, it can be seen that the embodiments of the low-slump concrete mixer truck of this utility model have at least one or more of the following advantages:
[0040] 1. The low slump concrete mixer truck provided by this utility model can effectively guide low slump concrete into the mixing drum 1 through the setting of the guide plate 4, reduce the phenomenon of material blockage, and avoid the problem of low material loading efficiency caused by poor fluidity.
[0041] 2. The low slump concrete mixer truck provided by this utility model has a significantly larger loading channel than the smaller diameter of the connecting ring 3 (about 35 cm) in the prior art. The diameter of the connecting ring 3 is not less than 45 cm, which allows the low slump concrete to enter the mixing drum 1 more smoothly and improves the loading efficiency.
[0042] 3. The low slump concrete mixer truck provided by this utility model significantly improves the unloading speed of low slump concrete by increasing the angle between the unloading chute 6 and the ground to not less than 35° (e.g., 37°), avoiding the problems of slow concrete flow and accumulation caused by too small an angle, and improving unloading efficiency.
[0043] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0044] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
