Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an intelligent cement-based grouting material mixer. Background Art

[0002] Cement-based grouting materials are usually used for grouting in occasions such as bolt anchoring, structural reinforcement, and prestressed channels. They are a kind of building material made by mixing raw materials such as cement, aggregate, admixture, and water in a certain proportion. They have the characteristics of high fluidity and self-leveling. Generally, a high-pressure grouting machine is used to inject the grouting materials into the designated position at the opened channel. When in use, the grouting materials are mixed with a specified amount of water in a mixer. After sufficient stirring, they can be used for grouting operations. The inventors found during use that the existing grouting material mixers can only stir the area where the stirring blades are located sufficiently by relying on the stirring blades when in use. The grouting materials above and below the stirring blades cannot be fully combined with water. The fluidity of the grouting materials is poor during stirring, and the staff needs to use other tools to poke the grouting materials up and down to improve its fluidity. On the one hand, this method has certain risks for the staff, and on the other hand, the grouting materials are relatively thick and the auxiliary stirring effect is poor. Utility Model Content

[0004] The technical solution of this utility model is as follows:

[0009] In order to improve the stability and balance of the telescopic cylinder driving the installation tube to move, two groups of telescopic cylinders are provided and are respectively located on both sides of the driving motor, and the output ends of the two groups of telescopic cylinders are connected to the installation tube.

[0010] In order to ensure that the telescopic cylinder drives the installation barrel to have a larger moving space and ensure that more grouting materials can be stirred in the vertical direction, the inner diameter of the installation barrel is not less than the maximum width of the stirring blade.

[0011] In order to increase the stirring force of the auxiliary blades on the grouting material in the vertical direction, the auxiliary blades are configured in a sheet shape and are installed obliquely with respect to the installation tube.

[0012] In order to facilitate the unloading of the mixing drum, a unloading port is arranged at the bottom of the mixing drum.

[0013] In order to facilitate the quick discharge of the grouting material, a clamp is installed on the outer edge of the mixing drum, and a rotating shaft is arranged on the side of the clamp. The rotating shaft passes through the bracket and is rotatably connected thereto, and both ends of the U-shaped frame are fixed to the rotating shaft.

[0014] In order to facilitate the rotation of the mixing drum and discharge the grouting material, a pushing frame is installed on one side of the U-shaped frame.

DETAILED DESCRIPTION

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0027] Example

[0028] As mentioned in the background technology, the grouting material needs to be mixed with water in a mixer and fully stirred before the grouting operation is carried out. However, when the mixer is in use, the inventor found that there are certain defects. Only the grouting material in the area of ​​the mixing blade 7 is stirred more fully. Although the grouting material above and below the mixing blade 7 can also slowly enter the mixing area during the mixing process, the flow speed is relatively slow, and the staff needs to use tools to speed up its flow. In this way, safety and efficiency cannot be guaranteed. Therefore, the inventor made improvements and designed a new type of mixing blade 7, which is explained in detail below with reference to the diagram.

[0029] This embodiment provides an intelligent cement-based grouting material mixer. Figure 1 and Figure 2, including a U-shaped base frame 1 and a U-shaped frame 2, the opening of the U-shaped base frame faces the horizontal direction, and two brackets 3 are relatively installed on the upper end of the U-shaped base frame 1, that is, the two brackets 3 are installed on the upper ends of two parallel opposite sides of the U-shaped base frame 1, and a mixing drum 4 is installed between the two brackets 3, and the upper end of the mixing drum 4 is arranged to be open, which is convenient for feeding, and a moving wheel 18 is installed at the bottom of the U-shaped base frame 1 to facilitate the movement of the mixer, and the U-shaped frame 2 is opened downward and arranged across the mixing drum 4, that is, the middle connecting part of the U-shaped frame 2 is located above the mixing drum 4, and is located directly above, and its two ends are respectively installed with the two brackets 3, and one of the main design points of this scheme is that the mixing drum 4 can rotate around the bracket 3, which is convenient for unloading at the upper end.

[0030] Specifically, a clamp 12 is installed on the outer edge surface of the mixing drum 4. The clamp 12 is provided with two upper and lower parts, and the clamp 12 is locked to the mixing drum 4 by means of bolts and nuts, and the upper and lower clamps 12 are connected by a connecting frame. The upper clamp 12 is located at the height of the top of the bracket 3, and a rotating shaft 13 is provided on the side of the clamp 12. Two rotating shafts 13 are provided, which are located on both sides of the mixing drum 4 opposite to each other. The two rotating shafts 13 both penetrate the bracket 3 and are rotatably connected thereto, so that the mixing drum 4 can rotate around the top of the bracket 3 through the rotating shaft 13, and the two ends of the U-shaped frame 2 are fixed to the rotating shaft 13, that is, when rotating, the U-shaped frame 2 can rotate synchronously with the mixing drum 4.

[0031] Secondly, in order to be able to intelligently control the grouting material and water added to the mixing drum 4, a gravity sensor 17 is installed on the U-shaped base frame 1, and the bracket 3 is installed on the gravity sensor 17, and the gravity sensor 17 is connected to the display screen, which can display the weight of the grouting material. The gravity sensor 17 is a purchased part, and the connection with the display screen and the bracket 3 is all existing technology. Specifically, the SWC515-A CS series sensor can be used, and the required maximum load-bearing capacity can be determined according to the actual size of the mixing drum and the actual production needs. The load-bearing steps before mixing can be reduced, and a certain amount of grouting material and water can be directly added to the mixing drum 4 in turn. Through the gravity sensor 17 and the display screen, the added weight can be easily read, making the mixer more intelligent.

[0032] In addition, in order to facilitate the rotation of the mixing drum 4, Figure 2A pushing frame 14 is installed on one side of the U-shaped frame 2. The pushing frame 14 is also set to be U-shaped, with an opening facing the mixing drum 4, and both ends are connected to the U-shaped frame 2 respectively. When the mixing drum 4 needs to be rotated to unload, the pushing frame 14 can be held by hand, and for the overall stability, the U-shaped base frame 1 can be stepped on, and the pushing frame 14 can be pulled upward to drive the mixing drum 4 to rotate around the bracket 3 through the U-shaped frame 2, and then the grouting material is unloaded at the upper end of the side of the mixing drum 4 away from the pushing frame 14. In order to speed up the unloading speed, the upper end of the side of the mixing drum 4 away from the pushing frame 14 is connected with a duckbill type unloading hopper 15. On the one hand, it speeds up the unloading speed, and on the other hand, it can make the flow of the grouting material more stable and the position more accurate during unloading.

[0033] It should be noted that in order to enable the mixing drum 4 to have multiple unloading methods, a unloading port 11 is provided at the bottom of the mixing drum 4, and a valve is provided at the unloading port 11. If a small flow rate unloading or unloading while stirring is required, the valve can be opened to unload at the unloading port 11.

[0034] In this embodiment, combined with Figure 3 A driving motor 5 is installed in the middle position of the U-shaped frame 2, and the output end of the driving motor 5 is connected to a stirring shaft 6, and the stirring shaft 6 extends into the mixing drum 4 and is installed with a stirring blade 7, and the stirring blade 7 is located near the bottom of the mixing drum 4, and the stirring blade 7 includes four bent stirring rods, which are respectively installed in four directions of the stirring shaft 6, and are installed opposite to each other in pairs. As one of the other main design points of this scheme, a telescopic cylinder 8 is also installed on the U-shaped frame 2, and the output end of the telescopic cylinder 8 extends into the mixing drum 4 and is connected to a mounting cylinder 9, and a plurality of auxiliary rods are installed circumferentially on the outer edge surface of the mounting cylinder 9. The auxiliary blades 10 can drive the installation barrel 9 to move up and down through the reciprocating motion of the telescopic cylinder 8, and then drive the circumferentially installed auxiliary blades 10 to move up and down in the mixing barrel 4, so as to stir the grouting material up and down, thereby accelerating the flow of the grouting material, so that the grouting material above and below the mixing blade 7 can quickly enter the mixing area of ​​the mixing blade 7, so that the grouting material can be quickly and fully mixed, and the telescopic cylinder 8 is provided with two groups, and is respectively located on both sides of the driving motor 5, and the output ends of the two groups of telescopic cylinders 8 are connected to the installation barrel 9. The setting of the two groups of telescopic cylinders 8 can drive the installation barrel 9 to move up and down more stably and balancedly.

[0035] On the basis of the above structure, the inner diameter of the mounting cylinder 9 is not less than the maximum width of the stirring blade 7, that is, the maximum distance between the two relative stirring rods is not greater than the inner diameter of the mounting cylinder 9. In this embodiment, the inner diameter of the mounting cylinder 9 is greater than the maximum width of the stirring blade 7, so that when the telescopic cylinder 8 drives the mounting cylinder 9 to move up and down, it can pass through the stirring blade 7, and can extend the path of the mounting cylinder 9 to move up and down, thereby ensuring the maximum stirring of the grouting material in the mixing cylinder 4 in the vertical direction, thereby accelerating the flow of the grouting material in the upper and lower parts.

[0036] It should be noted that an observation port 16 is provided on the outer edge of the mixing drum 4, and a transparent sealing material is installed at the observation point. The transparent sealing material can be made of glass or plastic plate. The observation port 16 is set to a waist-shaped hole structure, which is convenient for observing the grouting material in the mixing drum 4 during stirring.

[0037] Moreover, combined with Figure 3 The auxiliary blades 10 are configured to be sheet-shaped and are installed obliquely with the mounting barrel 9, and the auxiliary blades 10 are arranged in two groups up and down along the mounting barrel 9 to improve the stirring effect. A scraper ring is provided on the outer side of one end of the auxiliary blade 10 away from the mounting barrel 9, and multiple auxiliary blades 10 are installed with the scraper ring. The length of the auxiliary blades 10 should ensure that the scraper ring can be arranged in contact with the inner wall of the mixing barrel 4, which can not only expand the stirring range, but also enable the scraper ring to scrape up and down along the inner wall of the mixing barrel 4 during the process of the scraper ring moving up and down with the mounting barrel 9, thereby reducing the amount of grouting material attached to the inner wall of the mixing barrel 4.
