[0029] The stirring mechanism 4 in this example also includes a driving motor 401 fixed to the top of the grouting barrel 1 by bolts, and the output end of the driving motor 401 is connected to the top of the rotating rod 402 through a coupling, and the rotating rod 402 is rotatably connected to the inner wall of the grouting barrel 1 through a bearing, and the outer wall of the rotating rod 402 is connected to a cross bar 4021 through a bearing, and the cross bar 4021 is fixedly connected to the inner wall of the grouting barrel 1 through bolts, and a seal is provided at the connection between the cross bar 4021 and the rotating rod 402. The rotation of the output end of the driving motor 401 drives the rotating rod 402 to rotate, and the rotation of the rotating rod 402 can drive the stirring plate 403 to rotate, thereby facilitating the stirring of the slurry inside the grouting barrel 1.

[0030] The bottom end of the rotating rod 402 in this example is sleeved with a rotating column 404, which is rotatably connected to the inner wall of the cross bar 4021 through a bearing, and a seal is provided at the connection between the rotating column 404 and the cross bar 4021. The rotating column 404 is rotatably connected to the inner wall of the first guide block 405 through a bearing, and a seal is provided at the connection between the first guide block 405 and the rotating column 404, and the bottom end of the rotating column 404 passes through the bottom of the first guide block 405, and the bottom end of the rotating column 404 is connected to the second guide block 406 by bolts, and the rotation of the rotating column 404 can drive the second guide block 406 to rotate, and the second guide block 406 rotates to guide the slurry in the grouting bucket 1 into the discharge pipe 2.

[0031] In this example, a first material guide groove 4051 is provided at the top of the first material guide block 405, and a second material guide groove 4061 is provided at the top of the second material guide block 406. The first material guide groove 4051 and the second material guide groove 4061 are staggered to facilitate quantitative transportation of the slurry in the grouting bucket 1 to the discharge pipe 2.

[0032] The bottom end of the rotating rod 402 in this example extends to the inside of the rotating column 404, and the outer wall of the rotating rod 402 is fixed with a fixed block 4022 by bolts, and the inner wall of the rotating column 404 is sleeved with a moving block 4041, and one end of the moving block 4041 is in an arc shape. The moving block 4041 is at the same horizontal height as the fixed block 4022. The fixed block 4022 can drive the moving block 4041 to rotate counterclockwise, and the fixed block 4022 will not drive the moving block 4041 to rotate clockwise.

[0033] In this example, one end of the moving block 4041 is fixedly connected to a spring 4042 , and the other end of the spring 4042 is fixedly connected to the inner wall of the rotating column 404 . The spring 4042 is used to provide a restoring force for the moving block 4041 to move horizontally.

[0034] In this example, a moving groove 4043 is opened inside the rotating column 404, and the moving groove 4043 matches the moving trajectory of the moving block 4041. The moving groove 4043 is used to ensure the stability of the horizontal movement of the moving block 4041 and prevent the moving block 4041 from detaching from the rotating column 404.

[0035] Working principle: According to Figure 2 As shown, when grouting of slurry is required, the slurry is first stored in the grouting bucket 1, and then the user controls the driving motor 401 to work, and the output end of the driving motor 401 rotates clockwise, and the output end of the driving motor 401 rotates to drive the rotating rod 402 to rotate, and the rotating rod 402 rotates to drive the stirring plate 403 to rotate, and the stirring plate 403 rotates to stir the slurry;

[0036] according to Figure 5 As shown, the rotation of the rotating rod 402 drives the fixed block 4022 to rotate at the same time, and the fixed block 4022 rotates clockwise and contacts one end of the moving block 4041. Since one end of the moving block 4041 is set in an arc shape, the fixed block 4022 squeezes the moving block 4041 to move toward the end close to the spring 4042, and the spring 4042 is squeezed. After the fixed block 4022 is separated from the moving block 4041, the spring 4042 returns to its original state and drives the moving block 4041 to reset and move, and so on. That is, the clockwise rotation of the fixed block 4022 will not drive the moving block 4041 to rotate;

[0037] according to Figure 2-Figure 5As shown, when the slurry needs to be output, the staff controls the output end of the driving motor 401 to rotate counterclockwise, and the counterclockwise rotation of the output end of the driving motor 401 drives the rotating rod 402 to rotate, and the rotation of the rotating rod 402 drives the fixed block 4022 to rotate counterclockwise, and the fixed block 4022 rotates and squeezes one side of the moving block 4041, thereby driving the moving block 4041 to rotate, and the rotation of the moving block 4041 drives the rotating column 404 to rotate, and the rotation of the rotating column 404 drives the second material guide block 406 to rotate, and the rotation of the second material guide block 406 drives the second material guide trough 4061 to rotate, when the second material guide trough 4061 is at the same vertical position as the first material guide trough 4051, the slurry in the grouting bucket 1 enters the discharge pipe 2 through the first material guide trough 4051 and the second material guide trough 4061, and then is discharged into the foundation pit through the discharge pipe 2, and after the first material guide trough 4051 and the second material guide trough 4061 are misaligned, the slurry in the grouting bucket 1 cannot be discharged, and this cycle repeats.

[0038] Finally, the stirring plate 403 is driven to rotate by rotating the rotating rod 402, and the stirring plate 403 rotates and stirs the slurry in the grouting bucket 1 to ensure the uniformity of the slurry when the slurry is output. At the same time, when the slurry is discharged, the stirring plate 403 rotates and stirs the slurry to avoid blockage when the slurry is discharged. In addition, through the setting of the first material guide groove 4051 and the second material guide groove 4061, when the first material guide groove 4051 and the second material guide groove 4061 are in the same vertical position, the slurry in the grouting bucket 1 can be transported to the discharge pipe 2. In this way, the slurry can be quantitatively injected into the designated area, and the uniformity of the slurry injection in the injection area can be improved by quantitatively discharging the slurry.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
