Description

Technical Field

[0001] The invention relates to the technical field of mine filling, in particular to a grouting and filling device for overburden separation layer. Background Art

[0002] Overburden delamination refers to the phenomenon in which fine debris particles slide downward after the rock layer is damaged during the mining process, causing the rock to float or even fall off, resulting in reduced rock stability and surrounding rock damage. Overburden delamination is a common phenomenon in mining, especially in coal mining. Coal mine overburden delamination grouting technology is used to solve mining engineering problems such as surface subsidence control, coal-based solid waste disposal, water resource protection, and mining earthquake prevention. It is a source-reduction mining method that achieves surface subsidence reduction, water conservation and emission reduction, and shock absorption and impact prevention.

[0003] Overburden separation grouting filling devices play an important role in mining and other fields, but the existing devices have some problems that need to be solved urgently: in terms of slurry stirring, it is difficult to achieve sufficient and uniform stirring of the slurry. The traditional stirring blade design is relatively simple, and the flow pattern of the slurry in the stirring barrel is single, resulting in the slurry in some areas cannot be effectively stirred, and precipitation and stratification are prone to occur. This not only affects the quality of grouting, but may also cause blockage of the grouting pipeline and reduce work efficiency.

[0004] Furthermore, current systems make multi-directional adjustment of grouting pipes extremely inconvenient. These pipes are typically connected to fixed components, making them rigid and lacking the flexibility to rotate and swing. This makes it difficult to accurately adjust their angle and position based on actual grouting needs. This makes it difficult to precisely inject slurry into the target location when faced with complex overburden delamination situations, thus compromising the effectiveness of grouting.

[0043] In the specific implementation process, Figure 3-6 As shown, a concentrically distributed outer gear ring 4 is fixed to the inner top wall of the mixing container 3 , and a concentrically fixed planetary gear 10 is sleeved on the top end of each planetary shaft 9 , and each planetary gear 10 is meshed with the outer gear ring 4 .

[0044] The top end of the hollow outer cylinder 6 is sleeved with a first end face gear 7 which is fixed concentrically and has teeth facing upwards. The top end of the hollow inner cylinder 14 is sleeved with a second end face gear 16 which is fixed concentrically and has teeth facing downwards.

[0060] Specifically, the working principle and operation method of the present invention are as follows:

[0061] Step 1: Close the electromagnetic communication valve 5 and pour the filling material into the feed hopper 15.

Under the driving action of the servo motor 25, the motor shaft of the servo motor 25 drives the notched disk 26 and the pair of toggle pins 27 to rotate synchronously. The notched portion of the notched disk 26 forms a limiting effect with the inner three-claw disk 24, and the pair of toggle pins 27 forms a limiting effect with the outer three-claw disk 24, thereby driving the fixed shaft 22 and the fixed gear 23 to rotate intermittently.

[0062] Step 2: The fixed gear 23 engages to drive the second end gear 16 and the first end gear 7 to rotate forward and reverse respectively. The second end gear 16 synchronously drives the hollow inner cylinder 14, the feed hopper 15, the spiral shaft 18, the spiral blade 19, and the conical blade 20 to rotate forward. The spiral blade 19 and the conical blade 20 drive the filling material to roll upward and stir.

[0063] The first end face gear 7 synchronously drives the hollow outer cylinder 6, the three-claw ring 8, the planetary shaft 9, the driven swing arm 11, the stirring shaft 12, and the stirring paddle 13 to rotate in the opposite direction. The planetary gear 10 synchronously meshes and rotates along the outer gear ring 4, thereby driving the planetary shaft 9, the driven swing arm 11, the stirring shaft 12, and the stirring paddle 13 to perform planetary rotation. The filling material is uniformly stirred by the plurality of stirring paddles 13, so that the filling material is stirred and mixed into a slurry.

[0064] Step 3: Under the driving action of the first motor 34, the motor shaft of the first motor 34 drives the first driving pulley, the first belt 35, the first driven pulley, and the first connecting shaft to rotate synchronously. The first belt 35 drives the first connecting rod 37 to translate along the "X" axis through the first rectangular ring 36. Under the hinged action of the first connecting rod 37 and the second connecting rod 38, the hexagonal disk 28, the grouting pipe 31, and the grouting end 32 are driven to translate along the "X" axis.

[0065] Step 4: Under the driving action of the second motor 39, the motor shaft of the second motor 39 drives the second driving pulley, the second belt 40, the second driven pulley, and the second connecting shaft to rotate synchronously. The second belt 40 drives the third connecting rod 42 to translate along the "Y" axis through the second rectangular ring 41. Under the hinged action of the third connecting rod 42 and the fourth connecting rod 43, the hexagonal disk 28, the grouting pipe 31, and the grouting end 32 are driven to translate along the "Y" axis.

[0066] Step 5: Under the driving action of the third motor 44, the motor shaft of the third motor 44 drives the third driving pulley, the third belt 45, the third driven pulley, and the third connecting shaft to rotate synchronously. The third belt 45 drives the fifth connecting rod 47 to translate along the "Z" axis through the third rectangular ring 46. Under the hinged action of the fifth connecting rod 47 and the sixth connecting rod 48, the hexagonal disk 28, the grouting pipe 31, and the grouting end 32 are driven to translate along the "Z" axis.

[0067] Step six, control the hexagonal disk 28, the grouting pipe 31, and the grouting end 32 to move to the specified position through the first motor 34, the second motor 39, and the third motor 44, and insert the grouting pipe 31 and the grouting end 32 downward to the specified depth, open the electromagnetic connecting valve 5, and control the motor shaft of the servo motor 25 to rotate in the opposite direction, and the slurry in the mixing container 3 is injected downward into the overburden separation layer along the electromagnetic connecting valve 5, the telescopic hose 30, the grouting pipe 31, and the grouting end 32, thereby completing the overburden separation layer grouting filling operation.

[0068] The filling material of the present invention flows into the mixing container 3 through the feed hopper 15 and the hollow inner cylinder 14. The servo motor 25 drives the relevant components to stir the filling material into a slurry. At the same time, the first, second, and third motors respectively drive the corresponding pulleys and belt systems, driving the connecting rod to translate along the X, Y, and Z axes, thereby controlling the hexagonal disk 28, the grouting pipe 31, and the grouting end 32 to move to the specified position and insert them into the specified depth.

[0069] Open the electromagnetic connecting valve 5, control the servo motor 25 to reverse, and the slurry in the mixing container 3 is injected downward into the overburden separation layer through the electromagnetic connecting valve 5, the telescopic hose 30, the grouting pipe 31, and the grouting end 32, so as to achieve precise positioning, depth control and efficient grouting, ensure the quality of grouting filling, improve the stability of the overburden, and reduce the risk of geological disasters.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
