[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5 The bottom plate 1 is provided with a storage box 3 (which may be filled with gangue) and a mixing tank 4 (which may be concrete) as the filling material. For the filling material, it can also be other materials, such as universal joints, etc., which can be conveniently rotated with the front end of the walking wheel 2, so as to facilitate turning when walking. A connecting frame 12 is welded at the front end of the rotating frame 11, which can be conveniently connected with the front of the vehicle, so as to facilitate the movement of the whole vehicle through the front of the vehicle, and facilitate the filling operation. A storage box 3 (which may be filled with gangue) and a mixing tank 4 (which may be concrete) are installed on the bottom plate 1. For the filling material, it can also be other materials, which can be selected according to the situation to ensure the filling effect. It is a relatively mature technology and will not be described here.

[0026] See also Figure 1-Figure 5In order to facilitate the filling of the gangue, the large-size particles are filled first, and then the small-size particles are filled to ensure the filling effect. The top of the storage box 3 (the side wall of which can be hinged with a box door through a hinge to facilitate the subsequent maintenance or opening operation during cleaning) is equipped with a feed port 5 for adding gangue, and the mounting blocks 17 of the plug-in mechanism are equidistantly installed inside (located on the inner wall side wall of the storage box 3, one side wall is high and the other side wall is low), and a fixing column 18 is vertically welded on the mounting block 17, and a rubber sleeve 19 is provided on the outside, and the mounting frame 1 of the filter assembly 3 is provided with a fixing hole 16 for plugging with the fixing column 18. After plugging, the mounting frame 13 is tilted to facilitate filtering with the internal filter plate 14, and the side wall of the storage box 3 is provided with a first export plate 8 and a second export plate 9 (the outlets of which are both plugged with baffles, which can be easily removed during filling to facilitate the discharge and filling of gangue). The first export plate 8 matches the filter plate 14, and a guide plate 15 matching the second export plate 9 is provided inside the storage box 3. The first export plate 8 is convenient for discharging large-size gangue, and the second export plate 9 discharges small-size gangue.

[0027] See also Figure 1-Figure 5 Secondly, in order to fill concrete after gangue filling to ensure the filling effect, an addition port 7 for adding concrete is opened on one side of the top of the mixing tank 4, which is convenient for adding concrete during filling and use, and convenient for subsequent filling and filling. An injection pipe 10 is welded at an angle at the bottom end of the side wall of the mixing tank 4 to facilitate the discharge of grouting and filling operations. In order to ensure the mixing effect of concrete and avoid stratification, a motor 6 of a mixing assembly is installed on the top of the mixing tank 4. A rotating shaft 20 is fixedly installed at the output end of the motor 6 through a coupling. The rotating shaft 20 passes through the mixing tank 4 and extends to the inside where mixing rods 21 (which can also be mixing blades) are equidistantly welded to ensure the mixing effect.

After moving to the filling location, the gangue can be screened by the filter plate 14 in the installation frame 13 during the movement. By first removing the baffle on the first export plate 8, the large-size gangue is discharged for filling, and then the baffle on the second export plate 9 is removed, and the small-size gangue is discharged for filling with the guide plate 15. At the same time, the motor 6 is working, which can rotate with the rotating shaft 20 and the mixing rod 21, and the concrete can be mixed and stirred during the movement. After the gangue filling is completed, the concrete can be discharged through the injection pipe 10, and then the filling operation is carried out to ensure the filling effect. When the filter plate 14 needs to be disassembled or replaced, the installation frame 13 can be pulled upwards, and the fixing column 18 can be separated from the fixing hole 16, and it can be removed for easy cleaning or replacement.
