Description
Technical Field
[0001] This application relates to the field of mixing technology, and more specifically, to a concrete mixing device for civil engineering. Background Technology
[0002] When carrying out construction work in civil engineering, it is necessary to use mixing equipment to uniformly mix concrete raw materials so that they can form a good binder.
[0003] The prior art publication (announcement) number CN205033393U provides a concrete mixing equipment for civil engineering. In the related technology of this device, the transmission is more stable, the vibration is reduced, the service life is extended, the rolling of the equipment is avoided during the loading and unloading process, and the wear and vibration are further reduced.
[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following defects: the connection between the mixing tank and the supporting body is limited, and the gravity increases sharply after the raw materials are added to the mixing tank later, which can easily reduce the connection between the mixing tank and the supporting body, posing a safety hazard.
[0005] In view of this, we propose a concrete mixing equipment for civil engineering. Utility Model Content
[0006] To address the problems mentioned in the background art, this application provides a concrete mixing device for civil engineering.
[0007] The concrete mixing equipment for civil engineering provided in this application adopts the following technical solution:
[0008] A concrete mixing device for civil engineering includes a mixing tank. A mixing shaft is rotatably connected inside the mixing tank. One end of the mixing shaft passes through the mixing tank and is fixedly connected to a mixing motor. The mixing motor is fixedly connected to the side wall of the mixing tank through a motor sleeve. A connecting rod is provided on one side of the mixing motor. A conical ladder frame is fixedly connected to one end of the connecting rod, and a transfer ladder frame is fixedly connected to the other end. A reinforcing cross plate is fixedly connected between the transfer ladder frame and the conical ladder frame. A steering motor component that can mesh and drive with the mixing tank is fixedly connected to one side of the reinforcing cross plate with an electrical control box. Both the transfer ladder frame and the conical ladder frame are rotatably engaged with the mixing tank.
[0009] By adopting the above technical solution, the mixing tank is rotated and engaged with the transfer ladder and conical ladder, and under the meshing limit of the steering motor, the mixing tank is stably limited to the support of the transfer ladder and conical ladder. This not only allows the raw materials inside the mixing tank to be mixed under the agitation of the mixing shaft, but also allows the mixing tank to be adjusted to swing under the drive of the steering motor, thereby accelerating the mixing and stirring of the internal raw materials and facilitating the pouring and discharge of materials.
[0010] As an optional solution to the technical solution in this application, the mixing tank is formed by two hemispheres fixedly connected by bolts, and a gear groove is provided on one side of the mixing tank to mesh and be adapted to the steering motor.
[0011] By adopting the above technical solution, the mixing tank is formed by fixing two hemispheres together with bolts. This allows for cleaning of the mixing tank, avoids damage to the mixing tank caused by the solidification of the concrete inside, and enables regular disassembly and cleaning of the mixing tank to maintain its mixing performance.
[0012] As an optional solution to the technical solution of this application, a scraper ring is fixedly connected to the outside of the stirring shaft. The scraper ring is in clearance fit with the stirring tank body, and the cross-section of the scraper ring is set in a trapezoidal structure.
[0013] By adopting the above technical solution, the scraper ring with a trapezoidal cross-section can be made to follow the stirring shaft to rotate and scrape the inner wall of the mixing tank, thus maintaining the stability of the mixing tank during use.
[0014] As an optional solution to the technical solution of this application, the connecting rod is arranged in an arc shape, and a lifting ring is fixedly connected to the middle of the arc-shaped connecting rod.
[0015] By adopting the above technical solution, the connecting rod with an arc-shaped structure can not only strengthen the stability of the connection between the transfer ladder and the cone ladder, but also enable the entire device to be lifted and transferred under the traction of the lifting ring at the top of the connecting rod, thus enhancing the convenience of using the device.
[0016] As an optional solution to the technical solution in this application, the reinforcing horizontal plate has two slots on one side in a symmetrical structure, and the slots are engaged and limited with the transfer ladder and the cone ladder.
[0017] By adopting the above technical solution, the connection between the slot and the transfer ladder and the cone ladder is strengthened by using the locking and limiting mechanism.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. This application utilizes the rotatable engagement of the mixing tank with the transfer ladder and conical ladder, and under the engagement and limiting of the steering motor, the mixing tank is stably limited to the support of the transfer ladder and conical ladder. This not only allows the raw materials inside the mixing tank to be mixed under the agitation of the mixing shaft, but also allows the mixing tank to be adjusted to swing under the drive of the steering motor, thereby accelerating the mixing and stirring of the internal raw materials and facilitating the pouring and discharge of materials.
[0020] 2. This application utilizes two hemispheres fixedly connected by bolts to form a mixing tank, which enables the cleaning of the mixing tank, avoids damage to the mixing tank caused by the solidification of the concrete inside the mixing tank, and allows for regular disassembly and cleaning of the mixing tank, maintaining the mixing effect of the mixing tank.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.
[0029] Reference Figure 1-3The concrete mixing equipment for civil engineering described in this application includes a mixing tank 1. A mixing shaft 2 is rotatably connected inside the mixing tank 1. One end of the mixing shaft 2 passes through the mixing tank 1 and is fixedly connected to a mixing motor 3. The mixing motor 3 is fixedly connected to the side wall of the mixing tank 1 through a motor sleeve 4. A connecting rod 5 is provided on one side of the mixing motor 3. A conical ladder frame 6 is fixedly connected to one end of the connecting rod 5, and a transfer ladder frame 7 is fixedly connected to the other end. A reinforcing horizontal plate 8 is fixedly connected between the transfer ladder frame 7 and the conical ladder frame 6. A steering motor component 9 that can mesh and be adapted to the mixing tank 1 is fixedly connected to one side of the reinforcing horizontal plate 8, which is equipped with an electrical control box. Both the transfer ladder frame 7 and the conical ladder frame 6 are rotatably engaged with the mixing tank 1.
[0030] This concrete mixing equipment for civil engineering utilizes the rotatable engagement of the mixing tank 1 with the transfer ladder 7 and conical ladder 6, and under the engagement and limiting action of the steering motor 9, the mixing tank 1 is stably positioned on the support of the transfer ladder 7 and conical ladder 6. This not only allows the raw materials inside the mixing tank 1 to be mixed under the agitation of the mixing shaft 2, but also enables the mixing tank 1 to swing under the drive of the steering motor 9, accelerating the mixing and stirring of the internal raw materials and facilitating the pouring and discharge of materials.
[0031] Reference Figure 3 and Figure 1 In the concrete mixing equipment for civil engineering described in this application embodiment, the mixing tank 1 is formed by two hemispheres fixedly connected by bolts, and a gear groove 11 is provided on one side of the mixing tank 1 to mesh and be adapted to the steering motor 9.
[0032] This concrete mixing equipment for civil engineering uses two hemispheres fixedly connected by bolts to form a mixing tank 1. This allows for cleaning of the mixing tank 1, preventing damage to the mixing tank 1 caused by the solidification of the concrete inside, and enabling regular disassembly and cleaning of the mixing tank 1 to maintain its mixing performance.
[0033] Reference Figure 4 and Figure 3 In the concrete mixing equipment for civil engineering described in this application embodiment, a scraper ring 21 is fixedly connected to the outside of the mixing shaft 2. The scraper ring 21 is clearance-fitted with the mixing tank 1, and the cross section of the scraper ring 21 is set in a trapezoidal structure.
[0034] This concrete mixing equipment for civil engineering uses a scraper ring 21 with a trapezoidal cross-section to follow the mixing shaft 2 in its rotation, thereby scraping the inner wall of the mixing tank 1 to maintain the stability of the mixing tank 1 during use.
[0035] Reference Figure 5 and Figure 1In the concrete mixing equipment for civil engineering described in this application embodiment, the connecting rod 5 is arranged in an arc shape, and a lifting ring 51 is fixedly connected to the middle of the arc-shaped connecting rod 5.
[0036] This concrete mixing equipment for civil engineering uses an arc-shaped connecting rod 5 to not only strengthen the stability of the connection between the transfer ladder 7 and the conical ladder 6, but also to allow the entire equipment to be lifted and moved under the traction of the lifting ring 51 at the top of the connecting rod 5, thus enhancing the ease of use of the equipment.
[0037] Reference Figure 6 and Figure 1 In the concrete mixing equipment for civil engineering described in this application embodiment, the reinforcing horizontal plate 8 has two slots 81 on one side in a symmetrical structure. The slots 81 are engaged and limited with the transfer ladder 7 and the conical ladder 6.
[0038] This concrete mixing equipment for civil engineering enhances the stability of the connection between the three components by using a slot 81 to engage and limit the movement of the ladder 7 and the conical ladder 6.
[0039] Working principle: After the cover on one side of the mixing tank 1 is opened, concrete raw materials and water are injected into the mixing tank 1 in an appropriate ratio, and then the cover is closed.
[0040] Next, operate the electrical control box on the reinforced horizontal plate 8 to start the installation and setting program of the stirring motor 3 and the steering motor 9;
[0041] At this time, the working stirring motor 3 drives the stirring shaft 2 to mix and stir the materials inside the stirring tank 1, while the steering motor 9 rotates forward and backward under the set program, driving the meshing stirring tank 1 to swing between the cone ladder frame 6 and the transfer ladder frame 7, accelerating the mixing of the materials inside the stirring tank 1.
