Description

Technical Field

[0001] This utility model relates to the field of goaf filling technology, and in particular to a goaf filling device for ore bodies. Background Technology

[0002] During mining operations, the formation of goafs can lead to safety hazards such as surface subsidence and rock instability. To ensure safe mining operations and environmental protection, goafs typically need to be filled. Common filling techniques include dry filling, paste filling, and slurry filling.

[0003] However, existing technologies have problems. Traditional filling devices are limited in angle adjustment, resulting in insufficient filling density, uneven distribution of filling material, and voids in local areas, which affects structural stability. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to propose a filling device for mined-out areas of ore bodies, which can achieve multi-dimensional coverage and ensure uniform material distribution.

[0005] According to the present invention, a filling device for a goaf in a ore body includes a tracked chassis and a baffle. A support plate is fixed on the top of the tracked chassis, and a lifting assembly for controlling the baffle is fixed on the top of the support plate. A support seat is fixed on one side of the baffle, and a rotary joint and a first motor are fixed on the top of the support seat. A first gear is sleeved on the outer surface of the rotating tube of the rotary joint, and a second gear meshing with the first gear is fixed on the rotating end of the first motor.

[0006] The rotating end of the rotary joint is fixed with a telescopic conveying pipe that is rotatably connected to the baffle. A fixed seat is fitted on the outer surface of the telescopic conveying pipe. A second motor is fixed at the bottom of the fixed seat. A rotating seat fitted on the outer surface of the telescopic conveying pipe is fixed at the rotating end of the second motor. A filling head is fixed at the end of the telescopic conveying pipe away from the rotary joint.

[0007] Preferably, the lifting assembly includes a linear slide, a screw is rotatably connected inside the linear slide, a third motor is fixed to the top of the linear slide, and the rotating end of the third motor is fixed to the screw.

[0008] Preferably, the outer surface of the screw is fitted with a lifting block that is threadedly connected to it, and a pair of connecting rods are fixed between the lifting block and the baffle.

[0009] Preferably, a guide rod that passes through the lifting block is fixed to the top of the support plate.

[0010] Preferably, protective plates for protecting the telescopic conveying pipe are fixed at both ends of the fixed base.

[0011] Preferably, a pair of batteries for providing power to the user unit are fixed to the top rear end of the support plate.

[0012] Preferably, the end of the rotary joint away from the telescopic conveying pipe is connected to the pipe for conveying the filling material.

[0013] The beneficial effects of this utility model are:

[0014] 1. Traditional filling devices are prone to material accumulation or voids due to limited angle adjustment. This device, through the horizontal rotation and vertical swing function of the filling head, can achieve multi-dimensional coverage and ensure uniform material distribution. The filling head supports height, horizontal angle, and pitch angle adjustment, which can accurately cover different areas of the goaf.

[0015] 2. The flexible design of the telescopic conveying pipe further adapts to the complex contours of the goaf, reduces local voids, and significantly improves the filling density. Attached Figure Description

[0022] Reference Figure 1-5The ore body goaf filling device includes a tracked chassis 1 and a baffle 3. The tracked chassis 1 serves as the mobile and support base of the device, adapting to the complex terrain of the mining area and enabling flexible movement. A support plate 2 is fixed to the top of the tracked chassis 1, serving as the installation platform for the upper structure. A lifting assembly for controlling the up and down movement of the baffle 3 is fixed to the top of the support plate 2. A support seat 4 is fixed to one side of the baffle 3. A rotary joint 5 and a first motor 6 are fixed to the top of the support seat 4. A first gear 7 is sleeved on the outer surface of the rotating tube of the rotary joint 5. A second gear 8 that meshes with the first gear 7 is fixed to the rotating end of the first motor 6. The rotary joint is a D-type rotary joint. When the first motor 6 is turned on, the rotating end of the rotary joint 5 is driven to rotate 360° by the meshing transmission between the second gear 8 and the first gear 7.

[0023] The rotating end of the rotary joint 5 is fixed with a telescopic conveying pipe 9 that is rotatably connected to the baffle 3. A fixed seat 10 is fitted on the outer surface of the telescopic conveying pipe 9. A second motor 11 is fixed at the bottom of the fixed seat 10. A rotating seat 12 fitted on the outer surface of the telescopic conveying pipe 9 is fixed at the rotating end of the second motor 11. A filling head 13 is fixed at the end of the telescopic conveying pipe 9 away from the rotary joint 5. By starting the second motor 11, the second motor 11 drives the rotating seat 12 to rotate, thereby driving the rotating seat 12 to rotate around the axis of the telescopic conveying pipe 9, thereby adjusting the pitch angle of the filling head 13. By rotating the filling head 13 360° in the horizontal plane and swinging it in the vertical direction, the filling head 13 can cover different areas of the goaf.

[0024] The lifting assembly includes a linear slide 14, with a screw 15 rotatably connected inside the linear slide 14. A third motor 17 is fixed to the top of the linear slide 14, and the rotating end of the third motor 17 is fixed to the screw 15. A lifting block 16 is threadedly connected to the outer surface of the screw 15. A pair of connecting rods 19 are fixed between the lifting block 16 and the baffle 3. The third motor 17 drives the screw 15 to rotate, and the connecting rods 19 are driven through the threaded lifting block 16. The connecting rods 19 drive the baffle 3 to move vertically up and down.

[0025] A guide rod 18 that passes through the lifting block 16 is fixed to the top of the support plate 2 to ensure a smooth lifting process.

[0026] Both ends of the fixed base 10 are fixed with protective plates 20 to protect the telescopic conveying pipe 9. The protective plates 20 provide protection when the telescopic conveying pipe 9 rotates, reducing the risk of breakage.

[0027] The top and rear end of the support plate 2 are fixed with a pair of batteries 21 for providing power to the user unit. Using batteries 21 for power supply reduces the dependence on fixed power sources, making it particularly suitable for operations in remote mining areas.

[0028] The end of the rotary joint 5 away from the telescopic conveying pipe 9 is connected to the pipe that conveys the filling material.

[0029] In use, this device is moved to the target location in the goaf via the tracked chassis 1. The third motor 17 is started, driving the screw 15 to rotate. The lifting block 16 then raises the baffle 3 and filling head 13 assembly to the required height. The first motor 6 is started, and the second gear 8 meshes with the first gear 7, driving the rotary joint 5 and the telescopic conveying pipe 9 to rotate horizontally, aligning the filling head 13 with different positions in the goaf. The second motor 11 is started, driving the filling head 13 to swing around the axis of the telescopic conveying pipe 9 via the rotating base 12, adjusting its pitch angle to cover the vertical area of ​​the goaf. External filling material enters the rotary joint 5 through the conveying pipe and is then transported to the filling head 13 via the telescopic conveying pipe 9. The filling head 13, through rotation and swinging motion, evenly sprays the material into the gaps in the goaf. During the filling process, the height, horizontal angle, and pitch angle can be adjusted in real time as needed to ensure filling density.
