Technical Field
[0001] The utility model relates to the technical field of manufacturing inorganic binder stabilized materials, and particularly relates to a double-vibration stirring device for cement-stabilized macadam indoors. Background Technique
[0002] Cement-stabilized macadam mixture is a common pavement base material on roads. It is formed by mixing cement with crushed stones of specific particle sizes in a certain proportion, and through sufficient stirring, compaction and curing to form a hard and stable mixture. During the stirring process of cement-stabilized macadam mixture, macroscopically, this mixture can be regarded as cement mortar dispersed on the surface of aggregates to play a role in bonding and stabilizing. Through the traditional forced stirring method, macroscopic uniformity can be achieved quickly; however, microscopically, its internal structure is quite complex, consisting of aggregates, cement hydration products, unhydrated cement particles, capillary pores, microcracks, etc., and the distribution is extremely uneven. The traditional stirring method cannot achieve effective stirring, and the cooperation between materials is uneven. Therefore, a double-vibration stirring device for cement-stabilized macadam indoors is proposed to solve the above problems. Content of the Utility Model
[0003] The purpose of the utility model is to provide a double-vibration stirring device for cement-stabilized macadam indoors to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] As an optional scheme of a double-vibration stirring device for cement-stabilized macadam indoors described in the utility model, wherein: a double-vibration stirring device for cement-stabilized macadam indoors includes a machine case,
[0006] The bottom of the machine case is fixedly connected with sliding columns distributed front and back. The lower part of the sliding columns is slidably connected with sliding sleeves, and the bottom of the sliding sleeves is fixedly connected with a bottom plate;
[0007] A hollow stirring shaft is rotatably connected inside the machine case, and uniformly distributed stirring plates are installed on the outer side of the hollow stirring shaft;
[0008] A vibration assembly is installed on one side of the machine case, and a discharge pipe communicated with the machine case is arranged below the vibration assembly;
[0009] A motor is fixedly connected to the center of the bottom plate. The end of the main shaft of the motor is fixedly connected with a rotating plate, and a fixed sleeve is arranged on the outer side of the rotating plate. The top of the fixed sleeve is fixedly connected with the machine case, and a guiding block is installed inside the fixed sleeve;
[0010] The vibration assembly includes a mounting frame, a cylinder, and a moving block. The outside of the mounting frame is fixedly connected to the chassis. A cylinder is fixedly connected inside the mounting frame. The free end of the cylinder is fixedly connected to a moving block. A moving plate is fixedly connected to the outside of the moving block. The moving plate is arranged inside the hollow stirring shaft.
[0011] As an alternative solution of the indoor double-vibration stirring device for cement-stabilized macadam of the present invention, wherein: multiple groups of guiding blocks are provided, and the guiding blocks are arranged in a circular track inside the fixed sleeve. The side of the guiding block facing the bottom plate is arranged as an inclined surface.
[0012] During the stirring process of the cement-stabilized macadam mixture, from a macroscopic perspective, this mixture can be regarded as cement mortar dispersed on the surface of the aggregate to play a role in bonding and stabilizing. Through the traditional forced stirring method, macroscopic uniformity can be achieved quickly; however, from a microscopic perspective, its internal structure is quite complex, consisting of aggregates, cement hydration products, unhydrated cement particles, capillary pores, microcracks, etc., and the distribution is extremely uneven. The traditional stirring method cannot achieve effective stirring, and the cooperation between materials is uneven. The present invention adopts a double-vibration stirring scheme. First, the cylinder drives the moving block to move, and the moving block drives the moving plate to move. At this time, the moving plate moves back and forth, and at this time, it can strike the inner wall of the hollow stirring shaft, thereby realizing the vibration of the hollow stirring shaft. Then, the motor drives the rotating plate to rotate. The rotating plate contacts the guiding block, and at this time, it drives the guiding block to move upward, thereby causing the fixed sleeve and the chassis to move upward. The guiding block drives the fixed sleeve and the chassis to be in a high position. When the rotating plate separates from the guiding block, the fixed sleeve quickly drops to a low position and generates a vibration force, thereby realizing the vibration of the chassis. The cooperation of the two vibrations can ensure the uniform stirring of the cement slurry inside the chassis and can further save the amount of cement used.
[0013] As an alternative solution of the indoor double-vibration stirring device for cement-stabilized macadam of the present invention, wherein: a guiding frame is slidably connected inside the moving block, and the outside of the guiding frame is fixedly connected to the mounting frame.
[0014] As an alternative solution of the indoor double-vibration stirring device for cement-stabilized macadam of the present invention, wherein: rotating shafts are fixedly connected to both sides of the moving plate, and rotating cylinders are rotatably connected to the outside of the rotating shafts.
[0015] When the moving plate moves left and right, at this time, the hollow stirring shaft is in a rotating state. The use of the rotating shafts and rotating cylinders on both sides of the moving plate can enable the rotating cylinders to rotate by themselves. When the rotating cylinders contact the hollow stirring shaft, the rotating cylinders can rotate by themselves, thereby ensuring to avoid scratching the inner wall of the hollow stirring shaft and ensuring the normal use of the hollow stirring shaft.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] The utility model adopts a double vibration stirring scheme. First, the cylinder drives the moving block to move, and the moving block drives the moving plate to move. At this time, the moving plate moves back and forth, and at this time, it can strike the inner wall of the hollow stirring shaft, so as to realize the vibration of the hollow stirring shaft. The rotating plate is driven by the motor to rotate. The rotating plate contacts the guiding block. At this time, the guiding block is driven to move upward, and then the fixed sleeve and the machine box move upward. The guiding block drives the fixed sleeve and the machine box to be in a high position. When the rotating plate is separated from the guiding block, the fixed sleeve quickly falls to a low position and generates a vibration force, so as to realize the vibration of the machine box. The cooperation of the two vibrations can ensure that the cement slurry inside the machine box is stirred evenly and can further save the consumption of cement. The stirring mechanism of this device is: by stirring the materials to make them collide, convect and diffuse with each other, and finally achieve the homogeneity at the macroscopic and microscopic levels. Vibration stirring is to superimpose vibration on the basis of traditional forced stirring. Under the dual action of stirring and vibration, the material particles collide violently with each other, so as to enhance the convection and diffusion of the mixture, and finally achieve the overall homogeneity. Compared with the traditional stirring method, vibration stirring increases the number of squeezes and collisions between materials, destroys the cement clumps, accelerates the hydration reaction, optimizes the microscopic structure of the mixture, and strengthens the interface between the cement mortar and the aggregate. Therefore, it significantly improves the performance of the mixture, saves the consumption of cement and saves the stirring time;
[0018] When the moving plate moves left and right, the hollow stirring shaft is in a rotating state at this time. The use of the rotating shafts and the rotating cylinders on both sides of the moving plate can make the rotating cylinder rotate by itself. When the rotating cylinder contacts the hollow stirring shaft, the rotating cylinder can rotate by itself, so as to ensure that the inner wall of the hollow stirring shaft is not scratched and ensure the normal use of the hollow stirring shaft.

[0025] Embodiment 1
[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The present utility model provides a technical solution:
[0027] A double-vibration mixing device for cement-stabilized macadam indoors, including a chassis 1,
[0028] The bottom of the above-mentioned chassis 1 is fixedly connected with sliding columns 2 distributed front and back. The lower part of the above-mentioned sliding columns 2 is slidably connected with a sliding sleeve 3, and the bottom of the above-mentioned sliding sleeve 3 is fixedly connected with a bottom plate 4;
[0029] The inside of the above-mentioned chassis 1 is rotatably connected with a hollow mixing shaft 8, and a uniformly distributed mixing plate 11 is installed on the outside of the hollow mixing shaft 8;
[0030] One side of the above-mentioned chassis 1 is provided with a vibration assembly 9, and a discharge pipe 10 communicating with the chassis 1 is arranged below the above-mentioned vibration assembly 9;
[0031] The center of the above-mentioned bottom plate 4 is fixedly connected with a motor 5. The end of the main shaft of the above-mentioned motor 5 is fixedly connected with a rotating plate 6, and a fixed sleeve 7 is arranged outside the above-mentioned rotating plate 6. The top of the above-mentioned fixed sleeve 7 is fixedly connected with the chassis 1, and a guide block 12 is installed inside the above-mentioned fixed sleeve 7;
[0032] The above-mentioned vibration assembly 9 includes a mounting frame 901, a cylinder 902 and a moving block 903. The outside of the above-mentioned mounting frame 901 is fixedly connected with the chassis 1. The inside of the above-mentioned mounting frame 901 is fixedly connected with a cylinder 902. The free end of the above-mentioned cylinder 902 is fixedly connected with a moving block 903. The outside of the above-mentioned moving block 903 is fixedly connected with a moving plate 905, and the above-mentioned moving plate 905 is arranged inside the hollow mixing shaft 8.
[0033] The above-mentioned guide blocks 12 are arranged in multiple groups, and the above-mentioned guide blocks 12 are arranged in a circular track inside the fixed sleeve 7. The side of the above-mentioned guide blocks 12 facing the bottom plate 4 is arranged as an inclined surface.
[0034] During the mixing process of cement-stabilized macadam mixture, macroscopically, this mixture can be regarded as cement mortar dispersed on the surface of aggregates to play a role in bonding and stabilizing. Through the traditional forced mixing method, macroscopic uniformity can be achieved quickly. However, microscopically, its internal structure is quite complex, consisting of aggregates, cement hydration products, unhydrated cement particles, capillary pores, microcracks, etc., and the distribution is extremely uneven. The traditional mixing method cannot achieve effective mixing, and the cooperation between materials is uneven. The present utility model adopts a double-vibration mixing scheme. First, the cylinder 902 drives the moving block 903 to move, and the moving block 903 drives the moving plate 905 to move. At this time, the moving plate 905 moves back and forth, and at this time, it can strike the inner wall of the hollow mixing shaft 8, thereby realizing the vibration of the hollow mixing shaft 8. And the motor 5 drives the rotating plate 6 to rotate. The rotating plate 6 contacts the guiding block 12. At this time, it drives the guiding block 12 to move upward, and then the fixed sleeve 7 and the chassis 1 move upward. The guiding block 12 drives the fixed sleeve 7 and the chassis 1 to be in a high position. When the rotating plate 6 separates from the guiding block 12, the fixed sleeve 7 quickly falls to a low position and generates a vibration force, thereby realizing the vibration of the chassis 1. The cooperation of the two vibrations can ensure the uniform mixing of the cement mortar inside the chassis 1 and can also further save the amount of cement used. The mixing mechanism of this device is: by mixing the materials to make them collide, convect, and diffuse with each other, and finally achieve macroscopic and microscopic homogeneity. Vibration mixing is to superimpose vibration on the basis of traditional forced mixing. Under the dual action of mixing and vibration, the material particles collide violently with each other, thereby enhancing the convection and diffusion of the mixture, and finally achieving overall homogeneity. Compared with the traditional mixing method, vibration mixing increases the number of squeezes and collisions between materials, destroys the cement clumps, accelerates the hydration reaction, optimizes the microscopic structure of the mixture, and strengthens the interface between the cement mortar and the aggregates, thus significantly improving the various properties of the mixture.

[0037] Both sides of the moving plate 905 are fixedly connected with rotating shafts 907, and both sides of the rotating shafts 907 are rotatably connected with rotating cylinders 906.
[0038] When the movable plate 905 moves left and right, the hollow stirring shaft 8 is in a rotating state at this time. The use of the rotating shafts 907 and the rotating cylinders 906 on both sides of the movable plate 905 enables the rotating cylinders 906 to rotate by themselves. When the rotating cylinders 906 come into contact with the hollow stirring shaft 8, the rotating cylinders 906 can rotate by themselves, thereby ensuring that the inner wall of the hollow stirring shaft 8 is not scratched and ensuring the normal use of the hollow stirring shaft 8.
[0039] In this embodiment, a guide frame 904 is provided inside the moving block 903, and the guide frame 904 is convexly arranged. At this time, the wide part of the guide frame 904 is used to prevent the moving block 903 from sliding excessively, achieving the purpose of limiting.
