Description

Technical Field

[0001] The utility model relates to the technical field of concrete block preparation, in particular to a turbine mixer for preparing aerated concrete blocks. Background Technique

[0002] Aerated concrete blocks are a new type of building material with light weight, porous structure, good heat insulation and fire resistance, and can be nailed, sawed, planed and have a certain seismic resistance. A turbine mixer is a device that uses a turbine for mixing, mainly composed of components such as a reduction motor, a rotating rod, a driving bevel gear, a driven bevel gear, a mixing rod and turbine mixing blades.

[0003] For example, the utility model patent with the publication number CN214521082U discloses an efficient concrete mixer, which includes a mixing barrel with a feed inlet, a discharge outlet and a mixing component. The mixing component includes a machine shell, a mixing rotating shaft, a hollow rotating shaft, a first driving motor, a mounting plate, a second driving motor and a mixing rod. The top end of the mixing rotating shaft is in transmission connection with the output end of the first driving motor. The outer wall of the hollow rotating shaft is rotatably connected with the mounting plate through a bearing. A transmission turbine is fixedly installed on the outer wall of the top end of the hollow rotating shaft. A transmission worm is arranged in the machine shell and is in transmission connection with the output end of the second driving motor and is used to drive the transmission turbine to rotate. A scraping plate is fixedly installed at one end of the mixing rod.

[0004] However, in the prior art, the positions of the mixing blades of general turbine mixers are fixed, resulting in insufficient mixing of some parts in the concrete, uneven distribution of the components in the concrete, which not only affects the strength of the concrete, but also means that the mixing path is fixed, resulting in an increase in the resistance during the mixing process, thereby reducing the mixing efficiency. The reduction of the mixing efficiency not only increases the mixing time, but also affects the quality of the concrete. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems of low mixing efficiency and uneven component distribution after mixing caused by fixed mixing positions in the prior art, and to propose a turbine mixer for preparing aerated concrete blocks.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A turbine mixer for preparing aerated concrete blocks, including a mixing barrel, the top of the mixing barrel is fixedly connected with a feed inlet, and a driving mechanism is installed on the top of the mixing barrel;

[0007] The driving mechanism includes a first mounting frame and a moving frame. A rotating rod is rotatably connected to the top end of the first mounting frame. A first driving bevel gear is fixedly connected to the outer surface of one end of the rotating rod. A first stirring rod is rotatably connected to one side of the first mounting frame. A first driven bevel gear is fixedly connected to the outer surface of the top end of the first stirring rod. The first driven bevel gear is meshed and connected with the first driving bevel gear. A second driving bevel gear is slidably connected to the outer surface of one end of the rotating rod. A second driven bevel gear is meshed and connected to one side of the second driving bevel gear. A second stirring rod is rotatably connected to one side of the moving frame. The top end of the second stirring rod is fixedly connected to the second driven bevel gear. A second mounting frame is fixedly connected to the inner side of the moving frame. An extrusion wheel is rotatably connected to the inner side of the second mounting frame. A cam is fixedly connected to the outer surface of one end of the first stirring rod.

[0008] Preferably, a reduction motor is installed on one side of the first mounting frame, and the output end of the reduction motor is fixedly connected to the rotating rod.

[0009] Preferably, limiting blocks are symmetrically and fixedly connected to the outer wall of one end of the rotating rod. A sliding sleeve is fixedly connected to one end of the second driving bevel gear, and the sliding sleeve is slidably connected to the limiting block.

[0010] Preferably, a tension spring is arranged between the moving frame and the first mounting frame, and fixing rods are clamped at both ends of the tension spring.

[0011] Preferably, one of the first stirring rods is fixedly connected to the first mounting frame, and the other first stirring rod is fixedly connected to the moving frame.

[0012] Preferably, two limiting rods are symmetrically and fixedly connected to one side of the first mounting frame, and one end of the limiting rod is slidably connected to the moving frame.

[0013] Preferably, the bottom ends of the second stirring rod and the first stirring rod both penetrate through the mixing barrel, and turbine stirring blades are fixedly connected to the surfaces of the second stirring rod and the first stirring rod. Guide holes are formed in the surface of the mixing barrel, and the guide holes are slidably connected to the second stirring rod.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0015] 1. In the present utility model, after the reduction motor is started, it drives the first driving bevel gear and the second driving bevel gear to rotate, thereby driving the first stirring rod and the second stirring rod and the turbine stirring blades thereon to rotate and stir. This design can effectively improve the quality in the preparation process of concrete blocks. At the same time, the rotation of the first stirring rod also drives the rotation of the cam. Through the interaction between the cam and the extrusion wheel, the moving frame and the second mounting frame can be dynamically adjusted in position during the stirring process. This design change not only changes the stirring force of the second stirring rod but also makes the stirring more uniform.

[0016] 2. In the present utility model, when the moving frame moves away from the first mounting frame due to the pushing of the cam, the tension spring will be stretched, and the cam and the first stirring rod rotate together, resulting in a change in the distance for pushing the moving frame. The tension spring and the first stirring rod cooperate to reset the moving frame. Under the combined action of the cam, the extrusion wheel and the tension spring, the moving frame slides under the guidance of the two limiting rods to achieve stable displacement. This rapid displacement changes the position of the second stirring rod, thereby significantly improving the stirring effect of the second stirring rod and the turbine stirring blades, making the preparation of concrete blocks more uniform and efficient.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, the present utility model provides a turbine mixer for preparing aerated concrete blocks, including a mixing barrel 1, a feeding port 4 fixedly connected to the top of the mixing barrel 1, and a driving mechanism 3 installed on the top of the mixing barrel 1;

[0026] The driving mechanism 3 includes a first mounting frame 31 and a moving frame 36. A rotating rod 32 is rotatably connected to the top end of the first mounting frame 31. One end of the rotating rod 32 is fixedly connected with a first driving bevel gear 321 on its outer surface. A first stirring rod 33 is rotatably connected to one side of the first mounting frame 31. A first driven bevel gear 331 is fixedly connected to the outer surface of the top end of the first stirring rod 33. The first driven bevel gear 331 is meshed with the first driving bevel gear 321. A second driving bevel gear 322 is slidably connected to the outer surface of one end of the rotating rod 32. A second driven bevel gear 341 is meshed with one side of the second driving bevel gear 322. A second stirring rod 34 is rotatably connected to one side of the moving frame 36. The top end of the second stirring rod 34 is fixedly connected to the second driven bevel gear 341. A second mounting frame 37 is fixedly connected to the inner side of the moving frame 36. An extrusion wheel 371 is rotatably connected to the inner side of the second mounting frame 37. A cam 38 is fixedly connected to the outer surface of one end of the first stirring rod 33.

[0027] Next, specifically describe the specific settings and functions of this embodiment. When the reduction motor 2 operates, it drives the rotation of the rotating rod 32. The rotation of the rotating rod 32 drives the rotation of both the first driving bevel gear 321 and the second driving bevel gear 322 simultaneously. The first driving bevel gear 321 drives the rotation of the first driven bevel gear 331 meshed with it, while the second driving bevel gear 322 drives the rotation of the second driven bevel gear 341 meshed with it. With the rotation of the first driven bevel gear 331, the first stirring rod 33 starts to rotate; similarly, the rotation of the second driven bevel gear 341 drives the rotation of the second stirring rod 34. When the second stirring rod 34 and the first stirring rod 33 start to rotate, multiple turbine stirring blades 5 on their surfaces will perform stirring to improve the quality during the preparation of concrete blocks.

[0028] During this process, the rotation of the first stirring rod 33 also drives the rotation of the cam 38. When the cam 38 rotates, it exerts a force on the extrusion wheel 371, so that the moving frame 36 and the second mounting frame 37 are pushed by the cam 38 together and start to move away from the first mounting frame 31. Such a design can change the position of the second stirring rod 34, thereby adjusting the stirring force generated by the second stirring rod 34 during the stirring process and making the mixing more uniform.

[0029] Embodiment 2

[0030] As Figure 3 and Figure 4As shown, a reduction motor 2 is installed on one side of the first mounting bracket 31, and the output end of the reduction motor 2 is fixedly connected to the rotating rod 32. Symmetrically and fixedly connected to the outer wall of one end of the rotating rod 32 are limit blocks 324, and fixedly connected to one end of the second driving bevel gear 322 is a sliding sleeve 323, and the sliding sleeve 323 is slidably connected to the limit blocks 324. A tension spring 39 is provided between the moving frame 36 and the first mounting bracket 31, and fixed rods 35 are clamped at both ends of the tension spring 39. One of the first stirring rods 33 is fixedly connected to the first mounting bracket 31, and the other first stirring rod 33 is fixedly connected to the moving frame 36. Symmetrically and fixedly connected to one side of the first mounting bracket 31 are two limit rods 311, and one end of the limit rods 311 is slidably connected to the moving frame 36. The bottom ends of the second stirring rod 34 and the first stirring rod 33 both penetrate through the stirring barrel 1, and turbine stirring blades 5 are fixedly connected to the surfaces of both the second stirring rod 34 and the first stirring rod 33. A guiding hole 11 is formed on the surface of the stirring barrel 1, and the guiding hole 11 is slidably connected to the second stirring rod 34.

[0031] The effect achieved by the entire embodiment is that when the moving frame 36 is pushed away from the first mounting bracket 31 by the cam 38 due to the pressing wheel 371, this action will stretch the tension spring 39. As the cam 38 makes a circular motion centered on the first stirring rod 33, the pushing distance of the cam 38 on the moving frame 36 will change during its rotation. At this time, the elastic effect of the tension spring 39 is particularly important. It will cooperate with the rotation of the first stirring rod 33 to pull the moving frame 36 to start resetting and gradually return it to its initial position.

[0032] This reset mechanism ensures that the moving frame 36 will not continuously move away from the first mounting bracket 31 due to the pushing of the cam 38, thus maintaining the continuity and stability of the stirring process. At the same time, the elasticity of the tension spring 39 can also buffer the impact of the cam 38 on the moving frame 36 to a certain extent and extend the service life of the equipment.

[0033] Under the coordinated action of the cam 38, the pressing wheel 371 and the tension spring 39, the moving frame 36 can move back and forth. During this process, the moving frame 36 will slide on the surfaces of the two limit rods 311, and these two limit rods 311 play a guiding role to ensure the stability of the moving frame 36 when driving the second stirring rod 34 to displace. This stability not only helps to improve the stirring effect but also can prevent unnecessary vibrations and noises of the equipment during the stirring process.

[0034] Since the reciprocating movement of the moving frame 36 can quickly change the position of the second stirring rod 34, it enables the second stirring rod 34 and the turbine stirring blades 5 on its surface to better mix with the concrete. This rapid position change not only increases the uniformity of stirring but also helps to break up large pieces of materials or aggregates in the concrete, further improving the stirring effect. At the same time, due to the dynamic changes during the stirring process, the fluidity and plasticity of the concrete are also improved, making the finally prepared concrete blocks more uniform and dense, thus improving their overall quality.

[0035] Usage method and working principle of this device: When the reduction motor 2 starts and drives the rotating rod 32 to rotate, the rotating rod 32 will simultaneously drive the first driving bevel gear 321 and the second driving bevel gear 322 to rotate. The first driving bevel gear 321 meshes with the first driven bevel gear 331, causing it to start rotating, and then drives the first stirring rod 33 to rotate. At the same time, the second driving bevel gear 322 meshes with the second driven bevel gear 341, causing the second driven bevel gear 341 to rotate and driving the second stirring rod 34 to rotate. Multiple turbine stirring blades 5 on these two stirring rods will jointly carry out stirring to improve the quality during the preparation of concrete blocks.

[0036] As the first stirring rod 33 rotates, the cam 38 will also be driven to rotate. During the rotation of the cam 38, it will squeeze the squeezing wheel 371, thereby pushing the moving frame 36 and the second mounting frame 37 together and moving away from the first mounting frame 31. This movement changes the position of the second stirring rod 34, and thus changes the stirring force generated by it, making the stirred mixture more uniform.

[0037] When the moving frame 36 moves away from the first mounting frame 31 due to the push of the cam 38, the tension spring 39 will be stretched. Due to the common rotation of the cam 38 and the first stirring rod 33, the pushing distance of the cam 38 on the moving frame 36 will change. At this time, the tension spring 39 will play a role and cooperate with the rotation of the first stirring rod 33 to pull the moving frame 36 to start resetting.

[0038] Under the coordinated action of the cam 38, the squeezing wheel 371 and the tension spring 39, the moving frame 36 will reciprocate. During this process, the moving frame 36 will slide on the surfaces of the two limiting rods 311, playing a guiding role to ensure the stability of the moving frame 36 when driving the displacement of the second stirring rod 34.

[0039] Due to the rapid reciprocating movement of the moving frame 36, the position of the second stirring rod 34 changes rapidly, thus further improving the stirring effect of the second stirring rod 34 and the turbine stirring blades 5 on its surface.

[0040] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
