[0013] The second technical solution adopted by the present invention is a grouting backfilling method for mine crack repair, which specifically includes the following steps: Step 1: Move the nozzle on the material storage component to the top of the mine crack by a tractor, turn on the water pump on the guide tube, the water pump pumps the mortar in the material barrel to one end of the nozzle, injects the mortar into the crack, and turns on the first motor on the material storage component and the second motor on the mixing unit. The first motor drives the material barrel to flip, and the second motor drives several side rods on the rotating rod to rotate, so that the mortar in the material barrel is in motion, and the fourth motor on the oscillation component is turned on in coordination.

At the same time, the third hydraulic cylinder on the extension component drives the third hydraulic rod to adjust the movement range of the nozzle, and performs grouting backfilling operations on cracks at different distances.

[0014] Beneficial effects of the present invention: 1. Move the nozzle on the material storage assembly to the top of the mine crack by a tractor, and start the water pump on the conduit. The water pump pumps the mortar in the barrel to one end of the nozzle, injects the mortar into the crack, and starts the first motor on the material storage assembly and the second motor on the mixing unit. The first motor drives the barrel to flip, and the second motor drives several side rods on the rotating rod to rotate, so that the mortar in the barrel is in motion, which is conducive to comprehensive mixing of the mortar in the barrel and avoids the solidification of the mortar used to repair the mine cracks. On the one hand, it is conducive to better interaction between various components in the mortar, so that the cement particles are fully hydrated, the plasticity and fluidity of the mortar are increased, and its workability is improved, so that the mortar is easier to be transported through the conduit during the grouting process. On the other hand, it is conducive to ensuring that the mortar is uniform in composition as a whole, avoiding problems such as insufficient local strength and inconsistent setting time due to uneven distribution of components, and ensuring the stability of the mortar performance during the entire grouting process.

[0015] 2. By turning on the third motor on the adjustment component, the third motor drives the rotating plate to rotate and adjust the grouting direction of the nozzle, which is conducive to the nozzle injecting mortar into the crack accurately, improving the accuracy of the equipment during crack grouting backfilling, and cooperating with the second hydraulic cylinder on the tilting component to drive the second hydraulic rod to move, adjust the inclination angle of the nozzle, so that the nozzle can perform grouting operations on cracks with different directions, which is conducive to changing the injection direction and flow trajectory of the slurry, so that it can better adapt to the shape and internal structure of the crack, ensure that the grouting material can be directly injected into the crack, avoid slurry waste and pollution to unnecessary surrounding areas, and at the same time, through the cooperation between the adjustment component and the tilting component, it is conducive to shortening the time of grouting of non-standard cracks, thereby improving the work efficiency of crack grouting backfilling.

[0016] 3. By adjusting the first hydraulic cylinder on the assembly to drive the first hydraulic rod to move up and down, the height of the nozzle is adjusted, which is beneficial to changing the impact force when the slurry is sprayed into the crack. When the crack is deep and the internal structure is complex, appropriately increasing the height of the nozzle can enable the slurry to obtain greater kinetic energy, and better penetrate the obstacles or blockages in the crack with a stronger impact force, ensuring that the slurry can reach the deep part of the crack. For some shallow or fragile crack walls, lowering the height of the nozzle can reduce the impact force of the slurry and avoid damage to the crack wall, ensuring the stability of the original structure of the crack, so that the slurry can fill the crack more gently. At the same time, the third hydraulic cylinder on the extension assembly drives the third hydraulic rod to adjust the movement range of the nozzle to ensure that the movement range of the nozzle is wider, which is not only conducive to grouting backfilling operations on cracks at different distances, but also conducive to flexibly avoiding these obstacles, finding a suitable grouting position, and ensuring that the grouting work can proceed smoothly.

[0017] 4. By turning on the fourth motor on the oscillation component, the fourth motor drives the oscillation block at one end of the wire to move up and down in the crack, and oscillates and disperses the mortar injected into the crack. At the same time, the third motor on the adjustment component is turned on, the second hydraulic cylinder on the tilting component drives the second hydraulic rod to move, and the third hydraulic cylinder on the extension component drives the third hydraulic rod to move forward and backward. The position and orientation of the oscillation block on the oscillation component are adjusted, which is conducive to the omnidirectional oscillation operation of the mortar injected into the mine cracks by the oscillation block. On the one hand, for some complex, narrow or tortuous cracks, it is conducive to the smoother flow of mortar in the mine cracks, and can better fill in every corner and detail of the cracks, thereby helping to reduce filling dead corners and voids and improve the density of filling. On the other hand, by oscillating the mortar injected into the cracks, the bubbles in the mortar can be vibrated and rise to the surface, thereby being discharged, making the mortar denser and better fitting with the crack wall, thereby improving the backfilling and repairing effect of the mortar on the cracks.

A water pump 204 is installed on the conduit 205. The bottom of the conduit 205 is connected to the bottom of the inner wall of the barrel 203. By turning on the water pump 204 on the conduit 205, the water pump 204 pumps the mortar in the barrel 203 to one end of the nozzle 206 to inject the mortar into the cracks.

The first hydraulic cylinder 303 on the adjustment component 3 drives the first hydraulic rod 304 to move up and down, and adjusts the height of the nozzle 206, which is beneficial to changing the impact force when the slurry is sprayed into the crack. When the crack is deep and the internal structure is more complicated, appropriately increasing the height of the nozzle 206 can enable the slurry to obtain greater kinetic energy, and better penetrate obstacles or blockages in the crack with a stronger impact force, ensuring that the slurry can reach the deep part of the crack. For some shallower or more fragile crack walls, lowering the height of the nozzle 206 can reduce the impact force of the slurry, avoid damage to the crack wall, ensure the stability of the original structure of the crack, and enable the slurry to fill the crack more gently.
