DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a deep well sealing machine, such as Figure 1-5As shown, it comprises: a bottom plate 1, a sealing slurry mixing box 2 is arranged on the top of the bottom plate 1; a discharge port 3 is opened at the bottom of the sealing slurry mixing box 2, a solenoid valve 4 is arranged inside the discharge port 3, a cross 5 is fixedly connected to the top of the sealing slurry mixing box 2, a first motor 6 is fixedly connected to the top of the cross 5, a stirring shaft 7 is fixedly connected to the output end of the first motor 6, the bottom end of the stirring shaft 7 passes through the cross 5 and extends to the inside of the sealing slurry mixing box 2, and three groups of stirring blades 8 are evenly and fixedly connected to the outer surface of the stirring shaft 7 located inside the sealing slurry mixing box 2; a storage mechanism 9 for prolonging the solidification time of the sealing slurry is arranged between the sealing slurry mixing box 2 and the bottom plate 1; a conveying mechanism 10 for facilitating the disassembly and assembly of the hole sealer is arranged on the top of the bottom plate 1 away from the sealing slurry mixing box 2.

[0022] It should be noted that the user pours appropriate amounts of water, sealing materials and mineral inorganic quick-setting expansion sealing materials into the sealing slurry mixing box 2 at the same time, starts the first motor 6, and the output end of the first motor 6 drives the stirring shaft 7, and the stirring shaft 7 drives the stirring blades 8, so that the stirring blades 8 stir and mix the water, sealing materials and mineral inorganic quick-setting expansion sealing materials. After the mixing is completed, the solenoid valve 4 is opened, and the sealing slurry flows from the discharge port 3 into the storage mechanism 9 for storage, which solves the problem that although the current sealing machine has the functions of easy control, adjustment and fixing, it does not have the function of stirring and mixing water, sealing materials and mineral inorganic quick-setting expansion sealing materials, resulting in the need for manual stirring and mixing, which increases the labor of workers and the low mixing efficiency of the sealing slurry raw materials.

[0023] In a further preferred embodiment of the present invention, Figure 1 , 5 As shown, the storage mechanism 9 includes: a sealing slurry storage box 11 is arranged between the sealing slurry mixing box 2 and the bottom plate 1, and the four corners of the top of the sealing slurry storage box 11 are fixedly connected with support rods 12, and the top ends of the support rods 12 are fixedly connected to the sealing slurry mixing box 2; a second motor 13 is fixedly connected to one side of the sealing slurry storage box 11, and a transmission shaft 14 is fixedly connected to the output end of the second motor 13, and an end of the transmission shaft 14 away from the second motor 13 passes through the sealing slurry storage box 11 and extends to the interior of the sealing slurry storage box 11, and an auger blade 15 is fixedly connected to the outer surface of the transmission shaft 14 located inside the sealing slurry storage box 11.

[0024] In this embodiment, the second motor 13 is started, and the output end of the second motor 13 drives the transmission shaft 14, and the transmission shaft 14 drives the auger blades 15. The auger blades 15 stir the sealing slurry inside the sealing slurry storage box 11, thereby extending the solidification time of the sealing slurry inside the sealing slurry storage box 11 and improving practicality.

[0025] In a further preferred embodiment of the present invention, Figure 1 , 4As shown, a plurality of special-shaped baffles 16 are evenly and fixedly connected to the inner wall of the slurry sealing and mixing box 2 , and the special-shaped baffles 16 cooperate with the stirring blades 8 .

[0026] In this embodiment, the sealing slurry can be blocked to prevent the sealing slurry from generating a vortex due to the inertia of the rotating stirring blades 8 while the stirring blades 8 are stirring the sealing slurry, thereby preventing the sealing slurry raw materials from being unevenly mixed.

[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, a sealing ring 17 is sleeved on the outer surface of the stirring shaft 7 near the cross 5 , and the sealing ring 17 is fixedly connected to the cross 5 .

[0028] In this embodiment, the sealing performance of the connection between the stirring shaft 7 and the cross 5 is improved to prevent the sealing slurry from entering the interior of the first motor 6 through the gap between the output ends of the first motor 6 and causing damage to the first motor 6.

[0029] In a further preferred embodiment of the present invention, Figure 1 , 3 As shown, the conveying mechanism 10 includes: a grouting pump 18 is fixedly connected to the top of the bottom plate 1 away from the sealing grout mixing box 2, and the input end of the grouting pump 18 passes through the sealing grout storage box 11 and extends to the interior of the sealing grout storage box 11; the output end of the grouting pump 18 is fixedly connected to a flange 19, and a sealing gasket 20 is fixedly connected to the side of the flange 19 away from the grouting pump 18.

[0030] In this embodiment, the user connects the hole sealer to the flange 19 with bolts, and then starts the grouting pump 18. The grouting pump 18 draws the sealing slurry into the interior of the grouting pump 18 through the input end, and then transports the sealing slurry to the interior of the hole sealer through the output end to perform the hole sealing operation.

[0031] In a further preferred embodiment of the present invention, Figure 1 As shown, a controller 21 is fixedly connected to one side of the sealing and mixing box 2 , and the first motor 6 , the second motor 13 and the solenoid valve 4 are all electrically connected to the controller 21 .

[0032] In this embodiment, it is convenient for the user to control the start and stop of the first motor 6 and the second motor 13 and the opening and closing of the solenoid valve 4 .
