Description

Technical Field

[0001] The utility model relates to the technical field of concrete transportation, in particular to a mixing tank, a vehicle-mounted mixing device using the mixing tank, and a mixing transport vehicle using the vehicle-mounted mixing device. Background Art

[0002] Concrete is a product with unique properties, and one of its key properties, workability, can change over time. This change in workability is due to the continuous hydration of cement and other auxiliary binders in concrete. This change is unpredictable and uncontrollable. Finished concrete is delivered to the construction site using dedicated concrete trucks. Even if the workability of the concrete loaded onto the trucks is guaranteed to be acceptable, it is still difficult to guarantee that the concrete delivered to the construction site will still meet the requirements after 1-3 hours of transportation. This situation is exacerbated by traffic congestion or long transportation distances. As a result, substandard workability of concrete delivered to the construction site is common. This is a long-standing challenge in concrete quality control. If concrete is not exposed to water during transportation, the cement will not hydrate. Concrete workability can be effectively controlled by adding water to the concrete before delivery to the construction site and using it promptly after mixing. However, concrete mixer trucks are not capable of mixing dry materials. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the present utility model is to provide a mixing transport vehicle which can perform dry mixing and water-adding mixing on concrete according to the transportation time.

[0006] In order to solve the above technical problems, the embodiment of the present utility model provides a mixing tank capable of dry mixing, characterized in that it includes a rotating tank body and a stirring mechanism provided in the rotating tank body;

[0007] The stirring mechanism includes a spiral ribbon provided on the inner wall of the rotating tank, a turning plate for lifting the material, and a stirring member for stirring the material.

[0012] As an improvement of the above solution, the stirring plate is provided with a stirring surface for impacting the material, the facing direction of the stirring surface is opposite to the stirring direction of the rotating tank, and the stirring surface is a V-shaped surface or an arc-shaped surface.

[0013] As an improvement to the above solution, at least two spiral belts are provided on the inner wall of the rotating tank body to form a multi-spiral structure.

[0022] The central space of the rotating tank body serves as a mixing space. The spiral groove surrounds the mixing space, the turning plate is disposed within the spiral groove, and the stirring element is located within the mixing space. Therefore, the turning plate effectively lifts the material within the spiral groove. Once the material reaches a certain height, it loses the support of the turning plate and falls into the mixing space, thereby breaking it up. Accordingly, the stirring element further stirs and breaks up the material that falls into the mixing space. This ensures that the concrete raw materials are well mixed and broken up before water is added, and that the concrete can still be effectively stirred even after water is added and stirred.

[0023] Accordingly, the embodiment of the present utility model further discloses a vehicle-mounted mixing device using the above-mentioned mixing tank to achieve dry mixing and water-adding mixing of concrete;

[0024] Accordingly, the present invention also discloses a truck mixer using the aforementioned vehicle-mounted mixing device, which allows for dry mixing of concrete raw materials during transportation to improve the mixing effect of subsequent water mixing. Furthermore, water mixing can be performed in advance based on the arrival time at the destination, thereby resolving the problem of unpredictable and uncontrollable workability of existing water-mixed concrete during transportation, resulting in a high rate of unqualified deliveries. This allows for precise control of the workability of concrete delivered at the construction site, significantly improving the qualified rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] See also Figure 1 、 2 and 3. An embodiment of the present utility model provides a stirring tank, comprising a rotating tank body 1 and a stirring mechanism provided in the rotating tank body 1;

[0032] The stirring mechanism includes a spiral ribbon 2 provided on the inner wall of the rotating tank body 1, a turning plate 3 for lifting the material, and a stirring member 4 for stirring the material. The spiral ribbon 2 is spiral, so that a plurality of continuous spiral grooves 2a are formed on the inner wall of the rotating tank body 1 according to the pitch of the spiral ribbon 2.

[0033] The middle space of the rotating tank body 1 is a stirring space 1a. The spiral groove 2a surrounds the stirring space 1a. The turning plate 3 is arranged in the spiral groove 2a. The stirring member 4 is located in the stirring space 1a.

[0034] Specifically, one end of the turning plate 3 is connected to the inner wall of the rotating tank 1, and the other end is provided with a curved plate segment 31. The curved plate segment 31 is curved in a direction opposite to the stirring direction of the rotating tank 1, so as to lift the material in the spiral groove 2a upward when the rotating tank 1 rotates. Preferably, the angle formed between the curved plate segment 31 and the turning plate 3 is 100-150 degrees.

[0035] The stirring element 4 includes a stirring plate 41 and a connecting strip 42. The stirring plate 41 is connected to the inner side of the spiral ribbon 2 via the connecting strip 42, so that the stirring plate 41 is located in the stirring space 1a. The strip-shaped design of the connecting strip 42 can reduce the amount of material attached, allowing the material to pass through the stirring plate 41 and around the stirring plate 41 more effectively, thereby enhancing the stirring effect of the stirring plate 41.

[0036] Furthermore, in order to enhance the mixing effect of concrete, the mixing plate 41 is provided with a mixing hole 411 for materials to pass through. The setting of the mixing hole 411 enables the concrete raw materials to obtain a better mixing effect before or after adding water.

[0037] To address the problem of poor mixed fluidity caused by increased viscosity after adding water to concrete, the stirring plate 41 is provided with a stirring surface 412 for impacting the material. The stirring surface 412 faces in the opposite direction of the stirring direction of the rotating tank 1 and is V-shaped or curved. Preferably, the main body of the stirring plate 41 is a V-shaped plate structure, thereby forming the V-shaped surface.

[0038] Preferably, at least two spiral belts 2 are provided on the inner wall of the rotating tank 1 to form a multi-spiral structure. Figure 2 As shown, four spiral belts 2 are provided on the inner wall of the rotating tank 1 .

[0039] See also Figure 4 and 5 , the embodiment of the utility model further discloses a vehicle-mounted stirring device, comprising the stirring tank 5, a rotating device 7 for driving the rotating tank body 1 to rotate, and a spraying mechanism for spraying liquid into the rotating tank body 1;

[0040] The spraying mechanism includes a storage tank 61 for storing a preset agent, a pumping unit 62 and a spraying pipe 63 located in the rotating tank body 1. The storage tank 61, the pumping unit 62 and the spraying pipe 63 are connected in sequence to spray the agent inside the rotating tank body 1. Figure 1-3 The structures shown are the same and will not be described in detail here.

[0041] Therefore, the liquid required for production, such as water and water reducing agent, can be stored and discharged in the storage tank according to actual use requirements. The rotating device 7 is an existing technology in existing concrete mixer trucks, so its structural principle will not be described in detail here.

[0042] Preferably, a plurality of detachable nozzles 631 are spaced apart on the spray pipe 63 along the axial direction of the rotating tank 1. The nozzles 631 are located above the mixing space 1a, so as to better evenly sprinkle water and water reducing agent on the surface of the concrete dry material.

[0043] The pumping unit 62 includes a pump body 621 for pumping liquid, a pressure gauge 622, a check valve 623, and an upward pipe 624 for connecting to the spray pipe 63. The storage tank 61, pump body 621, pressure gauge 622, check valve 623, upward pipe 624, and spray pipe 63 are sequentially connected. The upward pipe 624 and the spray pipe 63 are connected by a detachable threaded connection. If the spray pipe 63 becomes excessively bonded to the concrete and cannot be used properly, only the spray pipe 63 can be replaced, thus facilitating daily maintenance.

[0044] See also Figure 5 The present invention also discloses a mixer truck, comprising the aforementioned on-board mixer 8 and a transport vehicle 9. The on-board mixer 8 is mounted on the transport vehicle 9, which is a conventional mixer truck body. Therefore, after the dry concrete raw materials are loaded onto the shoulder transport vehicle, dry mixing of the concrete raw materials is performed while the concrete is being transported to the destination, and water is added and mixed just before reaching the destination. This allows the mixer truck to have freshly processed concrete available upon arrival at the destination.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
