[0030] Reference Figure 2 The grouting mechanism 6 includes a liquid storage tank 61, which is fixedly connected to the upper end of the mobile vehicle 1. The upper end of the mobile vehicle 1 is fixedly connected to a pump 62. The inlet of the pump 62 is connected to the liquid storage tank 61 through a connecting pipe. The outlet of the pump 62 is connected to a buffer pipe 63. The buffer pipe 63 is slidably sleeved with a movable pipe 64. The outlet end of the movable pipe 64 is arranged downward.

[0031] Reference Figure 4 The support mechanism 8 includes a support frame 81, which is fixedly connected to the bottom end of the mobile vehicle 1, and the support frame 81 is slidably connected to the rotating frame 9. The rotating frame 9 is provided with a plurality of strip holes 82 at equal intervals along the axis direction. Both sides of the rotating frame 9 are fixedly connected with connecting bars 83, and one end of each connecting bar 83 is fixedly connected with a cleaning plate 84, and each cleaning plate 84 is located in the support frame 81. Both sides of the support frame 81 are fixedly connected with first connecting rods 85, and one end of each first connecting rod 85 is fixedly connected with a blocking frame 86;

[0032] Reference Figure 4 The rotating frame 9 includes a fixed ring 92, both sides of the fixed ring 92 are rotatably connected to the push plate 10, both sides of the fixed ring 92 are fixedly connected to the second connecting rods 91, each second connecting rod 91 is plugged into the connecting frame 7, both sides of the fixed ring 92 are connected to the connecting strips 83, each second connecting rod 91 is fixedly connected to the third connecting rod 93, one end of each third connecting rod 93 is connected to the first sliding wheel 94, and each first sliding wheel 94 is slidably connected to the support frame 81.

[0033] Working principle:

[0034] The mobile vehicle 1 is moved to the drilling position of the mine and fixed. After the electric telescopic rod 33 is powered on and started, it drives the movable plate 32 to move downward by a set distance and then reset. The movable plate 32 moves smoothly under the guidance of the groove frame 31. The movable plate 32 drives the motor 4 to move. The motor 4 drives the drilling auger 5 to move. The drilling auger 5 moves downward and passes through the through hole 2. The motor 4 also drives the connecting frame 7 to move downward. The connecting frame 7 slides on the second connecting rod 91. The relative distance between the second connecting rod 91 and the connecting frame 7 gradually decreases, providing a movable distance for the connecting frame 7 to move in the vertical direction.

[0035] At the same time, the output end of the motor 4 drives the drilling auger 5 to rotate, and the drilling auger 5 drills after contacting the mine ground. The drilling auger 5 moves downward by a set distance and drills a hole of a set depth. The output end of the motor 4 also drives the connecting frame 7 to rotate, and the connecting frame 7 drives the second connecting rod 91 to rotate, and the second connecting rod 91 drives the third connecting rod 93 to rotate, and the third connecting rod 93 drives the first sliding wheel 94 to rotate. During the rotation of the first sliding wheel 94, it rolls with the support frame 81, and the support frame 81 supports and limits the first sliding wheel 94. The first sliding wheel 94 supports the second connecting rod 91 through the third connecting rod 93, and the second connecting rod 91 limits and fixes the fixing ring 92, so that the fixing ring 92 is kept at the same height and the distance between it and the mine ground is constant;

[0036] The second connecting rod 91 also drives the fixing ring 92 to rotate, and the fixing ring 92 drives the push plate 10 to rotate. The push plate 10 tilts downward under its own gravity. The push plate 10 in a downward tilted state pushes the soil at the borehole mouth during the rotation process, so that the soil at the borehole mouth is dispersed outward, avoiding the accumulation of soil generated by the drilling at the borehole mouth, and reducing the height of the soil accumulation at the borehole mouth. When the drilling auger 5 moves upward and resets, when the soil thrown out from the drilling auger 5 collides with the soil accumulated at the borehole mouth, the soil at the borehole mouth is dispersed outward, reducing the height of the soil at the borehole mouth. After the thrown soil collides with the soil at the borehole mouth, the soil at the borehole mouth will not fall into the borehole, thereby improving the drilling effect.

[0037] After the drilling auger 5 moves upward and resets, the movable tube 64 is pulled. After the movable tube 64 is extended to the longest distance, the outlet end of the movable tube 64 is located above the through hole 2. After the pump 62 is started, the slurry in the liquid storage tank 61 is pumped out through the connecting pipe, and the pumped slurry enters the buffer tube 63. The slurry in the buffer tube 63 enters the movable tube 64. The slurry is released from the outlet end of the movable tube 64, and the released slurry passes through the through hole 2 into the borehole to grout the borehole. The movable tube 64 is moved so that the outlet end is located above the through hole 2, which is convenient for accurately introducing the slurry into the borehole.

[0038] Embodiment 2: The push plate 10 tilts downward under its own gravity, the bottom end of the push plate 10 is lower than the bottom end of the fixing ring 92, and the distance between the bottom end of the push plate 10 and the mine ground is small. When the mobile vehicle 1 is moving, the push plate 10 is easy to collide with objects on the mine ground, thereby hindering the movement of the mobile vehicle 1. After the push plate 10 collides with objects on the mine ground, it is easy to cause the push plate 10 to be damaged, thereby reducing the pushing effect of the push plate 10 on the soil. Figure 5As another preferred embodiment of the present invention, the difference from the embodiment 1 is that the mobile vehicle 1 is connected with a lifting mechanism 11 for changing the inclination of the push plate 10, and the lifting mechanism 11 includes two parallel connecting plates 111, one end of each connecting plate 111 is rotatably connected to the corresponding push plate 10, the upper ends of the two parallel connecting plates 111 pass through the through hole 2, and are rotatably connected with a first circular plate 112, and the bottom end of the first circular plate 112 is fixedly connected with a first spring 113, and the first spring 113 One end of the first circular plate 112 is fixedly connected to a second circular plate 114, the bottom end of the first circular plate 112 is fixedly connected to a plurality of guide rods 115, the bottom end of each guide rod 115 passes through the second circular plate 114, each second connecting rod 91 is fixedly connected to a limiting plate 117, each limiting plate 117 is in contact with the upper end of the second circular plate 114, the bottom end of the first circular plate 112 is connected to a plurality of second sliding wheels 116 at equal intervals along the axial direction, and each second sliding wheel 116 is in rolling contact with the upper end of the mobile vehicle 1.

[0039] Working principle:

[0040] When the movable plate 32 drives the motor 4 to move downward, the motor 4 drives the connecting frame 7 to move downward. After the connecting frame 7 moves downward for a distance, it contacts the upper end of the first circular plate 112. The connecting frame 7 continues to move downward. After the connecting frame 7 moves downward, it squeezes the first circular plate 112. The first circular plate 112 drives the guide rod 115 to move. The guide rod 115 slides on the second circular plate 114. Under the guidance of the guide rod 115, the first circular plate 112 moves downward smoothly. The first circular plate 112 drives the connecting plate 111 to move downward. After the connecting plate 111 moves, it pushes the push plate 10 to rotate downward, so that the distance between the bottom end of the push plate 10 and the mine ground is reduced, which is convenient for the push plate 10 to push the soil at the hole mouth and reduce the height of the soil at the hole mouth. After the first circular plate 112 moves downward, it squeezes the first spring 113. After the first spring 113 is compressed, it generates an elastic force, and the generated elastic force provides power for the push plate 10 to rotate upward and reset.

[0041] After the fixed ring 92 drives the push plate 10 to rotate, the push plate 10 drives the connecting plate 111 to rotate, the connecting plate 111 drives the first annular plate 112 to rotate, the first annular plate 112 drives the second annular plate 114 to rotate through the guide rod 115, the second annular plate 114 rolls on the upper end of the mobile vehicle 1 through the second sliding wheel 116, reducing the friction of the second annular plate 114 during the rotation process, and at the same time the limiting plate 117 limits the second annular plate 114 to prevent the second annular plate 114 from moving in the vertical direction, and the connecting plate 111 limits and fixes the push plate 10 during the rotation process, so that the push plate 10 is kept at the same height to push and disperse the soil, thereby reducing the height of the soil at the borehole mouth;

[0042] After the connecting frame 7 moves upward and resets, the connecting frame 7 is separated from the first annular plate 112, the first annular plate 112 loses the squeezing force, and the elastic force generated by the first spring 113 pushes the first annular plate 112 to move upward and reset. After the first annular plate 112 moves upward, it pulls the connecting plate 111, and the connecting plate 111 pulls the push plate 10 upward, and the push plate 10 rotates upward. After the push plate 10 rotates upward, the distance between the push plate 10 and the mine ground increases, and after the mobile vehicle 1 moves, the push plate 10 is not easy to collide with objects on the mine ground;

[0043] When drilling, the connecting frame 7 squeezes the first annular plate 112, and the first annular plate 112 drives the push plate 10 to rotate downward through the connecting plate 111, and the distance between the push plate 10 and the mine ground is reduced. After the drilling is completed, the elastic force generated by the first spring 113 pushes the first annular plate 112 to move upward and reset, and the first annular plate 112 pulls the push plate 10 upward through the connecting plate 111. After the push plate 10 rotates upward, the distance between the push plate 10 and the mine ground increases, and the distance between the push plate 10 and the mine ground is reduced during drilling, and the distance between the push plate 10 and the mine ground is increased after the mobile vehicle 1 moves, so that the soil generated by the drilling can be cleaned without blocking the movement of the mobile vehicle 1, and the mobile vehicle 1 will not collide with objects on the ground during the movement.

[0044] Embodiment 3: During the upward movement and reset process of the drilling auger 5, part of the soil dropped from the drilling auger 5 falls on the first circular plate 112, and the soil adheres to the upper end of the first circular plate 112. When the connecting frame 7 moves downward to squeeze the first circular plate 112, there is soil at the contact point between the connecting frame 7 and the first circular plate 112, and the connecting frame 7 moves downward for a certain distance. After the soil falls on the first circular plate 112, the thickness of the first circular plate 112 is increased, thereby occupying part of the space distance for the connecting frame 7 to move downward, so that the connecting frame 7 cannot move downward to the maximum distance, and thus cannot push the push plate 10 to rotate downward to the maximum distance. Figure 7-8 As another preferred embodiment of the present invention, the difference from Embodiment 2 is that a leveling mechanism 12 for cleaning the surface of the first circular plate 112 is connected to the upper end of the moving vehicle 1, and the leveling mechanism 12 includes two parallel guide columns 121, and a mounting plate 122 is slidably connected between the two parallel guide columns 121, and a second spring 123 is fixedly connected to the bottom end of the mounting plate 122, and one end of the second spring 123 is fixedly connected to the upper end of the moving vehicle 1, and a scraper strip 124 is fixedly connected to the mounting plate 122, and the scraper strip 124 contacts the upper end of the first circular plate 112, and a collecting box 125 is fixedly connected to the scraper strip 124, and the collecting box 125 contacts the outer side of the first circular plate 112, and the bottom end of the collecting box 125 is connected to a material guide pipe 126, and one end of the material guide pipe 126 passes through the moving vehicle 1.

[0045] Working principle:

[0046] The second spring 123 fixes the mounting plate 122, and the mounting plate 122 will not rotate under the limitation of the two guide pillars 121. The elastic force generated by the second spring 123 pulls the mounting plate 122 downward, and the mounting plate 122 is in close contact with the upper end of the first annular plate 112 through the scraper bar 124. The scraper bar 124 fixes the collecting box 125. The first annular plate 112 is in contact with the scraper bar 124 during the rotation process. After the first annular plate 112 rotates, it is relatively dislocated with the scraper bar 124. The scraper bar 124 is on the first annular plate 112. The upper end of the first circular plate 112 is scraped and cleaned, so that the adhered soil is separated from the first circular plate 112. As the scraped soil gradually increases, the scraped soil gradually falls into the collecting box 125, and the soil in the collecting box 125 is released to the ground through the guide tube 126, so as to prevent the soil from adhering to the upper end of the first circular plate 112, thereby not occupying the space for the connecting frame 7 to move downward, so that the connecting frame 7 can move downward to the maximum distance, thereby pushing the push plate 10 to rotate downward to the maximum distance, and maintaining the pushing effect of the push plate 10 on the soil.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
