Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a small cement concrete vibrating mixer. Background Technology

[0002] When mixing small-scale cement concrete, a small cement concrete vibrating mixer is often used. This is a device that uses vibration to fully mix materials such as cement, aggregates, and water. It is small in size, relatively easy to operate, and can be operated in a small space. It is suitable for some small projects or on-site mixing needs, such as home garden construction and small road repairs. It can ensure that the components of concrete are mixed evenly, improve the quality of concrete, and guarantee its strength and stability. It is both economical and practical.

[0003] Small-scale cement concrete vibrating mixer. First, add raw materials such as cement and sand to the mixing drum in proportion, then start the mixer. The mixing shaft drives the mixing blades to rotate, so that the raw materials are fully mixed. Next, turn on the vibration device to use the vibration force to expel air bubbles in the concrete and improve the density of the concrete. Finally, turn off the vibration device and continue mixing until the concrete is uniform and consistent, thus completing the mixing process.

[0004] Existing small-scale cement concrete vibrating mixers currently on the market have several problems in practical applications. From the unloading stage, traditional mixers mostly use gravity unloading or simple mechanical tilting unloading methods, resulting in slow unloading speeds. Especially if unloading cannot be completed in time before the concrete solidifies, material residue will remain, causing waste and increasing the difficulty of equipment cleaning and maintenance costs. In the mixing stage, existing small mixers mostly rely on a single rotating mixing blade. This mixing method makes it difficult to fully mix materials such as cement, sand, and water, easily leading to uneven mixing and dead zones, resulting in concrete strength and durability failing to meet ideal standards. Therefore, a small-scale cement concrete vibrating mixer is proposed to solve these problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 An embodiment of this utility model is provided: a small cement concrete vibrating mixer, including a support frame 1, which supports the weight of the whole machine and bears the torque and vibration of the mixing drum 11 during operation. A U-shaped frame 2 is fixedly connected to the top space of the support frame 1, which serves as the support and fulcrum for the mixing drum 11. Bearing seats are installed on both sides to support the rotating shaft 12. A mixing mechanism is provided on the top of the support frame 1, and a tilting and unloading mechanism is provided on the outside of the support frame 1.

[0035] The mixing mechanism includes a control box 3, which is responsible for controlling the operation of the drive component, thereby realizing the driving and control of the mixing mechanism. The drive component is set in the internal space area of ​​the control box 3. When the motor 4 is powered on, its drive end starts to rotate, driving the rotating shaft 5 to rotate together. The mixing speed and direction of the mixing paddle 13 in the mixing drum 11 can be adjusted to achieve full mixing of cement concrete. The drive end of the drive component is fixedly connected to the rotating shaft 5, which acts as a bridge and transmission between the motor 4 and the rotating rod 7, ensuring that the power can be smoothly transmitted to the mixing paddle 13 in the mixing drum 11 to achieve mixing of cement concrete.

[0036] A rotating drum 6 is fixedly connected to the right side of the inner wall of the support frame 1. It serves as a support component for the rotating rod 7, ensuring smooth transmission of the gear 8. During the stirring process, the rotating drum 6 rotates together with the rotating rod 7, but it does not directly participate in the stirring work. The rotating rod 7 is fixedly connected inside the rotating drum 6, which transmits the rotational motion of the rotating shaft 5 to the gear 8, thereby driving the transmission gear ring 9 and the outer ring 10 to rotate. The gear 8 is fixedly connected to the left side of the outer side of the rotating rod 7. When the rotating rod 7 drives the gear 8 to rotate, the gear 8 transmits power to the transmission gear ring 9 through meshing with it, thereby causing the outer ring 10 and the stirring drum 11 to rotate together.

[0037] The gear 8 is externally meshed with a transmission gear ring 9. When the gear 8 rotates, the transmission gear ring 9 rotates accordingly, transmitting power to the outer ring 10, thereby driving the mixing drum 11 to rotate together. Due to the annular structure of the transmission gear ring 9, the mixing drum 11 can rotate evenly in the horizontal direction, achieving full mixing of cement concrete. The outer ring 10 is fixedly connected to the top outer side of the transmission gear ring 9. During the mixing process, the outer ring 10 rotates together with the transmission gear ring 9, ensuring the stable operation of the mixing drum 11. The mixing drum 11 is fixedly connected to the space area in the inner wall of the outer ring 10. The rotation of the mixing drum 11 can make the material fully tumble and mix inside the drum, thereby achieving uniform mixing of cement concrete.

[0038] A rotating shaft 12 is rotatably connected to the bottom space of the mixing drum 11, providing a stable rotation center for the mixing drum 11, so that the mixing drum 11 can rotate smoothly under the drive of the motor 4. At the same time, the rotating shaft 12 can also transmit the torque received by the mixing drum 11 during the mixing process to the U-shaped frame 2, which is jointly borne by the U-shaped frame 2 and the support frame 1 to ensure the overall stability of the mixer. The mixing drum 11 is fixedly connected to the left and right sides inside. When the mixing drum 11 rotates, the mixing blades 13 also rotate, forcibly mixing the materials to make the concrete evenly mixed. The control box 3 is fixedly connected to the outside right side of the support frame 1.

[0039] The tilting and unloading mechanism includes a manual rotating wheel 14. The operator drives the mixing drum 11 to tilt and unload by rotating the manual rotating wheel 14. The wheel is marked with a scale to indicate the tilting angle. A fixed plate 15 is fixedly connected to the internal space area of ​​the manual rotating wheel 14. This plate is the connecting part between the manual rotating wheel 14 and the fixed joint 16 and transmits the rotational force.

[0040] A fixed connector 16 is fixedly connected to the inside right side of the fixed plate 15, which is inserted into the through hole 18 of the turntable 17 to realize the detachable connection between the manual turntable 14 and the turntable 17. The turntable 17 is fixedly connected to the outside right side of the manual turntable 14, which is the rotating part of the stirring drum 11. The angle positioning is realized by cooperating with the fixed connector 16 through the through hole 18. The outside of the manual turntable 14 is fixedly connected to the outside left side of the support frame 1.

[0041] Reference Figures 1 to 3 The drive assembly includes a motor 4, which is externally fixedly connected to the inside of the control box 3. The drive end of the motor 4 is fixedly connected to the outside of the rotating shaft 5. Multiple through holes 18 are provided on both the left and right sides of the inside of the turntable 17, which cooperate with the fixed joint 16 to realize multi-level positioning of the rotation angle of the stirring drum 11, with a positioning point every 30°. A rotating drum 19 is fixedly connected to the right side of the outside of the turntable 17, which is the support shaft for the rotation of the stirring drum 11. Bearings are installed inside to ensure that the stirring drum 11 rotates smoothly.

[0042] The external fixed connection of the rotating drum 19 is on the outer left side of the U-shaped frame 2. The external fixed connection of the fixed joint 16 is inside the through hole 18. The external right side of the support frame 1 is fixedly connected to two inclined plates 20, which support the placement plate 21, enhance the stability of the support frame 1, and also serve as the mounting bracket for the traveling wheel 23. The bottom of the two inclined plates 20 is fixedly connected to the placement plate 21 for placing the inclined plates 20, allowing the mixer to be moved or fixed when needed to prevent tipping.

[0043] Reference Figures 1 to 3 A horizontal column shaft 22 is fixedly connected to the bottom space of the placement plate 21. It serves as the support shaft for the traveling wheels 23 and bears the load when the whole machine moves. Traveling wheels 23 are fixedly connected to the left and right sides of the horizontal column shaft 22 to facilitate the movement and positioning of the mixer. The braking device can lock the wheels to prevent slippage during operation.

[0044] An indicator light 24 is fixedly connected to the outside right side of the control box 3. Red indicates that the power is on, yellow indicates that the mixing is in progress, and green indicates that the material is being unloaded. A start / stop button 25 is fixedly connected to the outside right side of the control box 3. In case of emergency, the power can be quickly cut off to ensure the safety of the equipment and personnel. The outside of the rotating drum 6 is fixedly connected to the outside right side of the U-shaped frame 2, and the bottom of the rotating shaft 12 is fixedly connected to the top of the U-shaped frame 2.

[0045] Working principle: By starting the motor 4 in the control box 3, the drive end of the motor 4 drives the rotating shaft 5 to rotate. The power is transmitted to the gear 8 through the rotating rod 7. The gear 8 meshes with the transmission gear ring 9, causing the outer ring 10 to drive the mixing drum 11 to rotate horizontally around the rotating shaft 12 on the U-shaped frame 2. At the same time, the mixing paddle 13 inside the mixing drum 11 rotates synchronously with the drum body, forcibly mixing the materials. By adjusting the parameters of the motor 4 in the control box 3, the mixing speed and direction can be changed to achieve full mixing of cement concrete.

[0046] After mixing is complete, the operator inserts the fixed connector 16 of the manual rotary wheel 14 into the through hole 18 of the turntable 17 at the corresponding angle, such as 30°, 60° or 90° positioning point. By rotating the manual rotary wheel 14, the operator drives the turntable 17 and the second drum 19 to rotate the mixing drum 11 around the second shaft 12 to the preset angle to complete the unloading. After unloading, the operator rotates the manual rotary wheel 14 in the opposite direction to reset the mixing drum 11. The operator can then pull out the fixed connector 16 to return to the mixing state.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
