However, during the blind hole grouting process, due to operational limitations, it is not convenient to use a vibrator. This may cause air bubbles to be mixed in during grouting, and these air bubbles will form voids in the concrete, thereby reducing its durability and strength. Content of the Utility Model

Detailed Embodiment

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0019] Such asFigures 1 to 3 As shown in the figure, a blind hole grouting device capable of reducing bubbles provided by an embodiment of the present invention includes a device body 1. The device body 1 includes support legs 2 fixedly arranged at the bottom of the device body 1 for support, and further includes:

[0020] An oscillation unit 3. The oscillation unit 3 includes an oscillation cylinder 4 arranged inside the device body 1. A support seat 5 is fixedly arranged on the inner wall of the device body 1 corresponding to the outside of the oscillation cylinder 4. Above the support seat 5, a plurality of groups of springs 6 are arranged. The lower end of the oscillation cylinder 4 is fixedly provided with a vibration motor 7. One side of the bottom of the oscillation cylinder 4 is fixedly provided with a slurry outlet 8. One end of the slurry outlet 8 penetrates through the side wall of the device body 1 and extends to the outside.

[0021] A stirring unit 9. The stirring unit 9 includes a sealing cover 10 arranged at the upper end of the device body 1. A plurality of groups of first bayonets 101 are fixedly arranged in an annular array on the inner side of the sealing cover 10. Second bayonets 102 are fixedly arranged on the upper end of the outside of the device body 1 corresponding to the first bayonets 101. A motor 11 is also fixedly arranged on the upper end of the sealing cover 10. The main shaft of the motor 11 is fixedly connected to a rotating shaft 12. The lower end of the rotating shaft 12 penetrates through the sealing cover 10 and extends into the device body 1. A spiral blade 13 is fixedly arranged on the outside of the rotating shaft 12. A grouting port 14 is also fixedly arranged on the upper end of the sealing cover 10.

[0022] In an embodiment of the present invention, mortar is poured into the device through the provided grouting port 14. The oscillation cylinder 4 cooperates with the vibration motor 7. Under the limiting and buffering action of the springs 6, the mortar in the oscillation cylinder 4 can be oscillated, thereby removing the bubbles existing in the mortar. Then, in cooperation with the rotation of the motor 11 driving the rotating shaft 12 and the spiral blade 13, under the spiral extrusion of the spiral blade 13, the mortar in the oscillation cylinder 4 can be evenly extruded along the slurry outlet 8, thereby reducing the bubbles doped into the mortar during the grouting process.

[0023] In an example of the present invention, during use, first, mortar is poured into the device through the grouting port 14. The mortar falls into the oscillation cylinder 4 under the action of gravity. The vibration motor 7 and the motor 11 are started. Under the oscillation action of the vibration motor 7, the bubbles in the mortar can be removed. At this time, the motor 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the spiral blade 13 to rotate to extrude the mortar in the oscillation cylinder 4. Under the extrusion of the spiral blade 13, the mortar is extruded from the slurry outlet 8.

[0024] As Figure 2 shown, as a preferred embodiment of the present invention, the oscillation cylinder 4 is arranged as a frustum-shaped container with a wider upper part and a narrower lower part, and the support seat 5 is arranged as an arc-shaped block with the same slope as the side surface of the oscillation cylinder 4.

[0025] In an example of the present utility model, by setting the oscillation cylinder 4 to have a structure that is thicker at the top and thinner at the bottom, it is convenient to defoam the mortar in the oscillation cylinder 4 during oscillation. Cooperating with the provided support base 5 and spring 6, it plays a role of limiting and buffering, facilitating the guarantee of the stability of the device.

[0026] As Figure 2 and Figure 3 shown, as a preferred embodiment of the present utility model, the side wall of the device body 1 is provided with a movable hole 81 corresponding to the slurry outlet 8. The diameter of the movable hole 81 is larger than the diameter of the slurry outlet 8, and the pipe orifice of the slurry outlet 8 has a taper. The first bayonet 101 is set as an arc-shaped plate with an "L" shape structure, and the second bayonet 102 is set as an arc-shaped plate adapted to the first bayonet 101.

[0027] In an example of the present utility model, by setting the diameter of the movable hole 81 to be larger than the diameter of the slurry outlet 8, during the oscillation of the oscillation cylinder 4, the collision between the side wall of the slurry outlet 8 and the edge of the movable hole 81 can be avoided. By setting the pipe orifice of the slurry outlet 8 to have a taper, it is convenient to connect the slurry outlet 8 with an external hose, thereby facilitating the grouting of the blind hole through the slurry outlet 8 and the hose. Through the provided second bayonet 102 and first bayonet 101, it is convenient to seal through the sealing cover 10 and the device body 1, preventing the internal mortar from being contaminated and also preventing the mortar from splashing out.

[0028] As Figure 2 shown, as a preferred embodiment of the present utility model, the spiral blade 13 is set as a spiral structure that is wider at the top and narrower at the bottom, and the spiral blade 13 is adapted to the slope of the oscillation cylinder 4.

[0029] In an example of the present utility model, by setting the spiral blade 13 to have a structure that is wider at the top and narrower at the bottom, it is convenient to extrude the mortar during rotation, and at the same time, it also plays a certain role in stirring to prevent the mortar from solidifying.
