[0002] Circulating mixing piles are a construction technology used for foundation treatment. They mainly use mechanical mixing to force the curing agent to mix with the in-situ soil to form a uniform pile, thereby improving the bearing capacity of the foundation, reducing settlement, or improving soil properties. However, in the current pile development process, the size of the mixing head is often fixed, resulting in a fixed diameter of the developed pile. When it is necessary to develop piles with different diameters, it is necessary to install mixing heads of different diameters, which is cumbersome and affects work efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a multi-directional mixing head for uniform forming of circulating mixing piles, which has the advantage of facilitating the construction of piles with different diameters.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional mixing head for uniformly forming a circulating mixing pile body, comprising a mixing body with a breaker hammer engaged at the bottom of the mixing body, a fixing plate fixedly installed on the outer side of the mixing body, a sliding groove provided inside the fixing plate, a slider slidably connected inside the sliding groove, a connecting plate fixedly installed on the inner side of the slider, a fixing block fixedly installed on the outer side of the connecting plate, and a first breaker blade fixedly installed on the outer side of the fixing block.

[0005] As a preferred embodiment of this utility model, the fixing plate has a positioning hole inside, and a positioning bolt engages inside the positioning hole, and the positioning bolt engages with the connecting plate.

[0006] As a preferred embodiment of this utility model, the mixing body has a discharge port inside, a support plate is fixedly installed on the outside of the mixing body, a telescopic rod is fixedly installed on the side of the support plate near the mixing body, a spring is sleeved on the outside of the telescopic rod, and a sealing plug is fixedly installed on the side of the spring away from the support plate, the sealing plug being located inside the discharge port.

[0007] As a preferred embodiment of this utility model, a protective sleeve is fitted onto the outer side of the spring, and second crushing blades are fixedly installed on both the front and rear sides of the support plate.

[0008] As a preferred embodiment of this utility model, a stirring plate is fixedly installed on the outer side of the stirring body, and a crushing tooth is fixedly installed on the bottom of the stirring plate. There are multiple crushing teeth, and all of the multiple crushing teeth are located above the support plate.

[0009] As a preferred embodiment of this utility model, a connecting block is fixedly installed above the support plate, and a third crushing blade is fixedly installed above the connecting block.

[0010] As a preferred embodiment of this utility model, the breaker hammer is an inverted cone shape, and the breaker hammer is located at the bottom of the sealing plug.

[0011] As a preferred embodiment of this utility model, the interior of the stirring body is provided with mounting holes, which are located above the fixing plates. There are two fixing plates, which are located on the left and right sides of the stirring body, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a groove inside a fixed plate, a slider slidably connected inside the groove, a connecting plate fixedly installed inside the slider, a fixing block fixedly installed outside the connecting plate, and a first crushing blade fixedly installed outside the fixing block. When it is necessary to jointly develop piles of different diameters, the connecting plate is first moved by the sliding connection between the slider and the groove, adjusting the distance between the fixing block and the fixed plate. After being adjusted to the designated position, the connecting plate is fixed by the engagement of the positioning bolt and the positioning hole.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a multi-directional mixing head for uniformly forming a circulating mixing pile body, including a mixing body 1, a breaker hammer 2 engaged at the bottom of the mixing body 1, a fixing plate 3 fixedly installed on the outer side of the mixing body 1, a sliding groove 4 opened inside the fixing plate 3, a slider 5 slidably connected inside the sliding groove 4, a connecting plate 6 fixedly installed on the inner side of the slider 5, a fixing block 7 fixedly installed on the outer side of the connecting plate 6, and a first breaker blade 8 fixedly installed on the outer side of the fixing block 7.

[0023] When it is necessary to jointly develop piles with different diameter values, the connecting plate 6 is first moved by the sliding connection between the slider 5 and the groove 4, so that the distance between the fixing block 7 and the fixing plate 3 is adjusted. After being adjusted to the designated position, the connecting plate 6 is fixed by the engagement of the positioning bolt 10 and the positioning hole 9. Then, the mixing body 1 is connected to the drive component above, so that the mixing body 1 is installed, and the fixing block 7 breaks up the soil, which facilitates the construction and development of piles with different diameter values ​​and saves overall installation efficiency.

[0024] The fixing plate 3 has a positioning hole 9 inside, and a positioning bolt 10 is engaged inside the positioning hole 9. The positioning bolt 10 engages with the connecting plate 6.

[0025] After the position of the fixing block 7 is adjusted, it engages with the fixing plate 3 and the positioning bolt 10 through the positioning hole 9 respectively, so that the connecting plate 6 is fixed, achieving the effect of maintaining fixation and stability.

[0026] The mixing body 1 has a discharge port 11 inside, and a support plate 12 is fixedly installed on the outside of the mixing body 1. A telescopic rod 13 is fixedly installed on the side of the support plate 12 close to the mixing body 1. A spring 14 is sleeved on the outside of the telescopic rod 13. A sealing plug 15 is fixedly installed on the side of the spring 14 away from the support plate 12. The sealing plug 15 is located inside the discharge port 11.

[0027] When working downwards, the sealing plug 15 is kept inside the discharge port 11 by the extension and retraction of the telescopic rod 13 and the elastic force of the spring 14, preventing excessive soil from entering the discharge port 11 and thus preventing blockage inside the mixing body 1. At the same time, when it is necessary to inject liquid solidification materials such as concrete into the pile body, the pressure generated by the liquid inside the mixing body 1 will squeeze the sealing plug 15 towards the support plate 12, causing the liquid to flow out from the discharge port 11, thereby facilitating the introduction of solidification materials.

[0028] Among them, a protective sleeve 16 is sleeved on the outside of the spring 14, and a second crushing blade 17 is fixedly installed on both the front and rear sides of the support plate 12.

[0029] The main function of the protective sleeve 16 is to protect the spring 14 and prevent dirt from getting stuck inside the spring 14, which would cause the spring 14 to lose its elasticity.

[0030] The mixing body 1 has a mixing plate 18 fixedly installed on its outer side, and a crushing tooth 19 fixedly installed on the bottom of the mixing plate 18. There are multiple crushing teeth 19, and all of them are located above the support plate 12.

[0031] When the mixing body 1 rotates, the crushing teeth 19 will mix the soil inside the crushed pile body, so that the soil inside is completely crushed, thereby achieving the effect of multi-directional mixing.

[0032] A connecting block 21 is fixedly installed above the support plate 12, and a third crushing blade 22 is fixedly installed above the connecting block 21.

[0033] The third crusher 22 is located below the crusher tooth 19. Its main function is to work with multiple crusher teeth 19 to perform multi-directional mixing, thereby quickly maintaining uniform solidification inside the pile and achieving a more stable effect.

[0034] Among them, the breaker 2 is an inverted cone shape, and the breaker 2 is located at the bottom of the sealing plug 15.

[0035] The main function of the hydraulic breaker 2 is to facilitate soil breaking while sealing the bottom of the mixing body 1, enabling rapid construction and maintaining downward stability.

[0036] The mixing body 1 has an installation hole 20 inside, which is located above the fixing plate 3. There are two fixing plates 3, which are located on the left and right sides of the mixing body 1 respectively.

[0037] The two fixing plates 3 are symmetrical and their main function is to keep the pile body cylindrical and vertically downward, thereby giving it stability after installation.

[0038] Working principle and usage process of this utility model:

[0039] Firstly, a groove 4 is provided inside the fixed plate 3, and a slider 5 is slidably connected inside the groove 4. A connecting plate 6 is fixedly installed inside the slider 5, and a fixing block 7 is fixedly installed outside the connecting plate 6. A first crushing blade 8 is fixedly installed outside the fixing block 7. When it is necessary to jointly develop piles with different diameter values, the connecting plate 6 is first moved by the sliding connection between the slider 5 and the groove 4, so that the distance between the fixing block 7 and the fixed plate 3 is adjusted. After being adjusted to the designated position, the connecting plate 6 is fixed by the engagement of the positioning bolt 10 and the positioning hole 9. Then, the mixing body 1 is connected to the drive assembly above, so that the mixing body 1 is installed, and the fixing block 7 crushes the soil, which facilitates the construction and development of piles with different diameter values ​​and saves overall installation efficiency.

[0040] Secondly, a telescopic rod 13 is fixedly installed on the side of the support plate 12 near the mixing body 1. A spring 14 is sleeved on the outside of the telescopic rod 13. A sealing plug 15 is fixedly installed on the side of the spring 14 away from the support plate 12. The sealing plug 15 is located inside the discharge port 11. When working downwards, the sealing plug 15 is kept inside the discharge port 11 by the telescopic action of the telescopic rod 13 and the elastic action of the spring 14, preventing a lot of soil from entering the discharge port 11 and thus preventing blockage inside the mixing body 1. At the same time, when it is necessary to inject liquid solidification materials such as concrete into the pile body, the pressure generated by the liquid inside the mixing body 1 will squeeze the sealing plug 15 towards the support plate 12, so that the liquid flows out from the inside of the discharge port 11, achieving the effect of facilitating the introduction of solidification materials.

[0041] Finally, after the pouring is completed, the breaker 2 is removed from the bottom of the mixing body 1, and the inside of the mixing body 1 is rinsed with clean water to prevent the solidified material from accumulating and clumping inside the mixing body 1, which could lead to blockages that cannot be cleaned.
