[0001] This utility model relates to the field of mining engineering, and in particular to a device for conveying filling slurry after mining. Background Technology

[0002] In mining operations, the transportation of filling slurry is a crucial step. The slurry is usually a mixture of cement, sand, water and other additives, used to fill the cavities left after mining. Post-mining filling operations usually refer to the injection of specific filling materials into the goaf after the mining of minerals in order to maintain or restore the stability of the underground structure of the mine, prevent surface collapse, and handle waste such as tailings.

[0003] Existing slurry conveying methods typically involve placing the slurry and other necessary equipment on a conveyor vehicle for transport. After being transported to the designated location, the equipment is installed on the ground and put into operation for grouting. However, current equipment lacks the ability to handle air bubbles and slurry adhesion. During the grouting process, air bubbles mixed into the slurry can easily affect its uniformity and density, while slurry adhesion can easily cause funnel blockage, severely impacting the grouting effect and efficiency, making it very inconvenient to use.

[0004] Therefore, it is necessary to design a grout conveying device that can tap the funnel during grouting to expel air bubbles in the grout, prevent the grout from sticking to the funnel and causing blockage, improve the grouting effect and efficiency, and be easy to use for filling grout after mining. Utility Model Content

[0005] To overcome the shortcomings of current equipment that lacks the ability to handle air bubbles and slurry adhesion, which can easily affect the uniformity and density of the slurry during the grouting process, and cause slurry adhesion to clog the funnel, severely affecting the grouting effect and efficiency and making it very inconvenient to use, this utility model provides a slurry conveying device for post-mining filling that can be used to knock the funnel during grouting, so as to expel air bubbles in the slurry, prevent the slurry from sticking to the funnel and causing blockage, improve the grouting effect and efficiency, and is easy to use.

[0006] Technical Solution: A slurry conveying device for post-mining filling includes a base plate, bottom wheels, support rods, connecting rods, connecting blocks, funnels, a first connector, a second connector, a conveying pump, a connecting pipe, a filter assembly, a striking assembly, and a fixing assembly. Two bottom wheels are rotatably connected to the left and right sides of the base plate. A support rod is connected to the upper left side of the base plate, and a connecting rod is connected to the lower right side of the support rod. A connecting block is connected to the right side of the connecting rod, and a funnel is connected to the connecting block. A first connector is connected to the upper right side of the support rod, and a second connector is detachably connected to the upper side of the first connector. A conveying pump is connected to the upper right side of the base plate, and the conveying pump is connected to the second connector. A connecting pipe is connected to the right side of the conveying pump, and a filter assembly for filtering the slurry is provided on the connecting pipe. A striking assembly for striking the funnel is provided on the lower front side of the support rod, and a fixing assembly for fixing the device is provided on the lower right side of the base plate.

[0007] To further explain, friction grooves are provided on all the bottom wheels.

[0008] To further explain, the diameter of the upper part of the funnel is larger than the diameter of the lower part.

[0009] To further explain, the filter assembly includes a clamping plate, a filter screen, a first motor, and a screw. The first motor is connected to the front of the connecting pipe, and the screw is connected to the output shaft of the first motor. The clamping plate is threaded onto the screw, and the clamping plate is slidably connected to the connecting pipe. The filter screen is clamped onto the upper part of the clamping plate.

[0010] To further explain, the striking assembly includes a second motor and a striking hammer. The second motor is connected to the lower front side of the support rod, and the striking hammer is connected to the output shaft of the second motor. The striking hammer is in contact with the funnel.

[0011] To further explain, the fixing component includes a cylinder and a fixing frame. The cylinder is connected to the lower right side of the base plate, and the fixing frame is connected to the telescopic end of the cylinder.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a delivery pump to make the slurry flow from the connecting pipe into the second connector, and then into the funnel for grouting. At the same time as grouting, the second motor drives the hammer to rotate and strike the funnel, thereby striking the funnel during grouting, so that air bubbles in the slurry are discharged, preventing the slurry from sticking to the funnel and causing blockage, improving the grouting effect and efficiency, and is easy to use.

[0013] 2. This utility model uses a delivery pump to allow the slurry to flow into the funnel for injection. When there are many impurities, the connecting pipe is blocked by the reverse movement of the clamping plate. Then the filter screen can be removed, cleaned, and reinstalled. This allows the filter screen to be installed to filter the slurry while being easy to remove and clean. It is convenient to remove large particles, undissolved solids, or other foreign objects from the slurry, thereby improving the quality of the slurry and facilitating the installation, removal, and replacement of the filter screen.

[0014] 3. This utility model moves the device to the location where grout needs to be filled, thereby facilitating the delivery pump to transport the grout. This causes the bottom wheel to rotate and move to the appropriate position. Then, the cylinder is activated, which drives the fixing frame to move and insert into the ground for fixation. The cylinder is then deactivated. This allows the device to be moved and transported to the designated position for fixation, preventing displacement of the device during grouting and improving the stability of the grouting process.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] A device for conveying backfill slurry after mining, such as Figures 1-5As shown, the assembly includes a base plate 1, bottom wheels 2, support rods 3, connecting rods 4, connecting blocks 5, funnels 6, first connectors 7, second connectors 8, a delivery pump 9, connecting pipes 14, a filter assembly, a striking assembly, and a fixing assembly. The base plate 1 has two bottom wheels 2 rotatably connected to its left and right sides. Each bottom wheel 2 has friction grooves to increase friction. The support rod 3 is connected to the upper left side of the base plate 1. The connecting rod 4 is connected to the lower right side of the support rod 3. The connecting block 5 is connected to the right side of the connecting rod 4. The funnel 6 is connected to the connecting block 5. The upper diameter of the funnel 6 is... The diameter of the support rod 3 is larger than that of the lower part, which facilitates feeding. The first connector 7 is connected to the upper right side of the support rod 3. The second connector 8 is detachably connected to the upper side of the first connector 7. The upper right side of the base plate 1 is connected to the conveying pump 9. The conveying pump 9 is connected to the second connector 8. The right side of the conveying pump 9 is connected to the connecting pipe 14. The connecting pipe 14 is equipped with a filter assembly for filtering the slurry. The lower front side of the support rod 3 is equipped with a striking assembly for striking the funnel 6. The lower right side of the base plate 1 is equipped with a fixing assembly for fixing the device.

[0023] like Figure 1 and Figure 4 As shown, the filter assembly includes a clamping plate 10, a filter screen 11, a first motor 12, and a screw 13. The first motor 12 is connected to the front side of the connecting pipe 14. The screw 13 is connected to the output shaft of the first motor 12. The clamping plate 10 is threadedly connected to the screw 13. The clamping plate 10 is slidably connected to the connecting pipe 14. The filter screen 11 is clamped onto the upper part of the clamping plate 10.

[0024] like Figure 2 As shown, the striking assembly includes a second motor 15 and a striking hammer 16. The second motor 15 is connected to the lower front side of the support rod 3, and the striking hammer 16 is connected to the output shaft of the second motor 15. The striking hammer 16 is in contact with the funnel 6.

[0025] like Figure 3 As shown, the fixing assembly includes a cylinder 17 and a fixing frame 18. The cylinder 17 is connected to the lower right side of the base plate 1, and the fixing frame 18 is connected to the telescopic end of the cylinder 17.

[0026] When filling slurry after mining, this device can be used. The bottom wheel 2 is in contact with the ground, and each bottom wheel 2 has friction grooves to increase friction. The filter screen 11 is then installed by engaging the clamping plate 10. The device is then moved to the location where slurry needs to be filled, thereby stimulating the conveying pump 9 to deliver the slurry. This causes the bottom wheel 2 to rotate. After moving to a suitable position, the cylinder 17 is activated, which drives the fixing frame 18 to move and insert into the ground for fixation. The cylinder 17 is then closed, thus moving and conveying the device to the designated position for fixation, preventing displacement during grouting and improving grouting stability. Subsequently, the first... The connector 7 contacts the second connector 8 and is then secured with bolts. A material conveying pipe is then connected to the connecting pipe 14. The first motor 12 is then started, driving the screw 13 to rotate. The screw causes the clamping plate 10 to move, moving the filter screen 11 to the position of the connecting pipe 14. The first motor 12 is then turned off, and the conveying pump 9 is started, allowing the slurry to enter the connecting pipe 14, flow through the filter screen 11 for filtration, then flow into the second connector 8, through the first connector 7, into the funnel 6 on the connecting block 5, and then out, flowing into the goaf area for filling. The upper diameter of the hopper 6 is larger than the lower diameter, facilitating material feeding. When there are many impurities on the filter screen 11, the first motor 12 reverses its operation, causing the screw 13 to rotate in the opposite direction. Under the action of the thread, the clamping plate 10 moves in the opposite direction to block the connecting pipe 14. Then, the filter screen 11 is removed for cleaning and reinstalled on the clamping plate 10. The above operation is repeated to move the filter screen 11 to the position of the connecting pipe 14 for continued filtration. This allows the filter screen 11 to be installed for filtration of the slurry while being easy to remove and clean, facilitating the removal of large particles, undissolved solids, or other impurities from the slurry. This device improves the quality of the slurry and facilitates the installation, removal, and replacement of the filter screen 11. During the grouting process, the second motor 15 on the support rod 3 is activated, which drives the hammer 16 to rotate and strike the funnel 6. This allows air bubbles in the slurry to be expelled, preventing the slurry from sticking to the funnel 6 and causing blockage, thus improving the grouting effect and efficiency. It is easy to use. After grouting is completed, the second motor 15 and the delivery pump 9 are turned off. Then, the cylinder 17 is reversed, causing the fixed frame 18 to move in the opposite direction and detach from the ground. The device is then moved to the next area for filling.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
