Description

Technical Field

[0001] This utility model relates to the field of mine restoration technology, specifically to a grouting device for mine restoration. Background Technology

[0002] Mine restoration refers to the remediation of pollution in abandoned mining areas, aiming to restore the damaged ecological environment and achieve sustainable use of land resources. During the mining process, a large amount of land that cannot be used without remediation is generated, also known as abandoned mining areas. These abandoned areas contain various types of pollution caused by production. During the restoration of abandoned mines, the mountain body needs to be reinforced, which requires drilling holes for internal grouting reinforcement.

[0003] In mining operations, the original topography and landforms are damaged. Reshaping the mining area's landform is the foundation of ecological reconstruction. Grouting restoration reduces the impact of mining on the ecological environment and shortens the ecological restoration period by grouting abandoned areas. However, when using existing grouting equipment, the grout is prone to solidification during storage and transportation, which reduces the fluidity of the grout. This not only affects the smooth progress of grouting but also reduces the effectiveness of grouting, making it difficult to effectively guarantee the quality of mining area restoration.

[0004] Therefore, it is necessary to modify it and set up a mixing mechanism to continuously stir the grout during the grouting process, which effectively avoids the problem of grout solidification, ensures good grout fluidity, makes the grouting process smoother, improves the grouting effect, and thus improves the quality of mine restoration. Utility Model Content

This device features a stirring mechanism that continuously agitates the grout during the grouting process, effectively preventing grout solidification, ensuring good grout fluidity, making the grouting process smoother, improving the grouting effect, and thus enhancing the quality of mine restoration. This solves the problem that existing grouting equipment often suffers from grout solidification during storage and transportation, leading to reduced grout fluidity, which not only affects the smooth progress of grouting but also reduces the grouting effect, making it difficult to effectively guarantee the quality of mine restoration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grouting device for mine restoration, comprising a support plate, a grouting pump fixedly connected to the right side of the top of the support plate, support rods fixedly connected to both the front and rear sides of the left side of the top of the support plate, a support ring fixedly connected to the top of the support rod, a positioning cylinder fixedly connected to the bottom of the support ring, a grouting pipe slidably connected inside the positioning cylinder, a grouting groove located below the grouting pipe on the left side of the support plate, a multi-stage electric telescopic rod fixedly connected to the left side of the top of the support plate, the top of the multi-stage electric telescopic rod fixedly connected to the left side of the grouting pipe via a support plate, the output end of the grouting pump communicating with the upper right side of the grouting pipe via a telescopic hose, a slurry tank provided on the top of the grouting pump, a drive motor fixedly connected to the top of the slurry tank, the output end of the drive motor penetrating into the interior of the slurry tank and fixedly connected to a shaft, a stirring frame fixedly connected to both the left and right sides of the shaft, and a stirring fan blade rotatably connected inside the stirring frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves moving the device above the mining area requiring repair, aligning the grouting groove with the pre-drilled hole, then activating the multi-stage electric telescopic rod to retract it, causing the grouting pipe to move downwards. The output end of the grouting pipe passes through the grouting groove and inserts into the pre-drilled hole. Grout is then added to the grout tank through the feeding hopper. The drive motor is activated, causing the shaft to rotate. This rotation of the shaft drives the stirring frame and stirring blades to agitate the grout inside the tank, improving its fluidity. The control valve is then opened to input the agitated grout into the grouting pump, which delivers the grout to the grouting pipe for grouting the holes in the mining area. After grouting is complete, the control valve and grouting pump are closed, allowing the multi-stage electric telescopic rod to extend and the grouting pipe to move out of the pre-drilled hole, thus enabling the device to be moved. This continuous agitation of the grout during the grouting process effectively prevents grout solidification, ensures good grout fluidity, and makes the grouting process smoother, improving the grouting effect and ultimately enhancing the quality of mining area repair.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a grouting device for mine restoration, including a bearing plate 1. A grouting pump 2 is fixedly connected to the right side of the top of the bearing plate 1. Support rods 3 are fixedly connected to both the front and rear sides of the left side of the top of the bearing plate 1. A support ring 4 is fixedly connected to the top of the support rod 3. A positioning cylinder 5 is fixedly connected to the bottom of the support ring 4. A grouting pipe 6 is slidably connected inside the positioning cylinder 5. A grouting groove 7 is opened on the left side of the bearing plate 1, located below the grouting pipe 6. A multi-stage electric telescopic rod 8 is fixedly connected to the left side of the top of the bearing plate 1. The top of the multi-stage electric telescopic rod 8 is connected to the grouting pipe 6 through a support plate. The left side is fixedly connected, and the output end of the grouting pump 2 is connected to the upper right side of the grouting pipe 6 through a telescopic hose. A grout tank 9 is provided on the top of the grouting pump 2. A bracket (not shown) is fixedly connected to the surface of the grout tank 9. The bottom of the bracket is fixedly connected to the top of the bearing plate 1. A filling hopper is connected to the top of the grout tank 9. A drive motor 10 is fixedly connected to the top of the grout tank 9. The output end of the drive motor 10 passes through the interior of the grout tank 9 and is fixedly connected to a shaft 11. A stirring frame 12 is fixedly connected to both the left and right sides of the shaft 11. A stirring fan blade 13 is rotatably connected inside the stirring frame 12.

[0022] refer to Figure 2 and Figure 3 The bottom of the grout tank 9 is connected to a control valve 14, the output end of which is connected to the input end of the grouting pump 2. The right side of the bottom of the grout tank 9 is connected to a drain valve 15. An annular nozzle 16 is fixedly connected to the upper part of the grout tank 9. The bottom of the annular nozzle 16 is provided with a number of evenly distributed nozzles, and the output ends of the nozzles are inclined downwards. The input end of the annular nozzle 16 extends through to the right side of the grout tank 9 and is connected to a water inlet valve pipe 17.

[0023] As a technical optimization of this utility model, by setting up the control valve 14, the drain valve 15, the annular nozzle 16 and the water inlet valve pipe 17 for coordinated use, after the device is used, the water inlet valve pipe 17 can be connected to the water supply pipeline to supply water to the annular nozzle 16, the control valve 14 can be closed to cut off the input of the grouting pump 2, the drain valve 15 can be opened, and the annular nozzle 16 can be used to spray and clean the inside of the grout tank 9. The sewage is discharged from the sorting valve to keep the inside of the grout tank 9 clean and prevent the grout from condensing inside the grout tank 9 so that it can be reused.

[0024] refer to Figure 3 Auxiliary stirring blades 18 are fixedly connected to the upper and lower sides of the left and right sides of the bottom of the shaft 11. A rubber scraper 19 is fixedly connected to the outer side of the stirring frame 12, and the outer side of the rubber scraper 19 is in contact with the inner wall of the slurry tank 9.

[0025] As a technical optimization of this utility model, by setting an auxiliary stirring blade 18, the sediment at the bottom of the slurry tank 9 can be stirred when the shaft 11 rotates, thereby improving the stirring effect and preventing sediment blockage. By setting a rubber scraper 19, the inner wall of the slurry tank 9 can be scraped by the rotation of the rubber scraper 19 when stirring or cleaning the slurry tank 9, thereby preventing the slurry from adhering to the inner wall of the slurry tank 9 and improving the stirring and cleaning effects.

[0026] refer to Figure 3 Hollow support legs 20 are fixedly connected to the four corners of the bottom of the support plate 1. A lifting electric telescopic rod 21 is fixedly connected to the upper part of the inner wall of the hollow support leg 20. A universal wheel 22 is fixedly connected to the output end of the lifting electric telescopic rod 21.

[0027] As a technical optimization of this utility model, by setting up hollow support legs 20, lifting electric telescopic rod 21 and universal wheels 22 in cooperation, the lifting electric telescopic rod 21 can be activated to drive the universal wheels 22 to move downward. When the universal wheels 22 contact the ground, the device is raised, making it convenient to move the device above the grouting area. When the grouting groove 7 is aligned with the pre-drilled hole, the lifting electric telescopic rod 21 can be retracted, the device is lowered, and the hollow support legs 20 contact the ground to fix the device.

[0028] refer to Figure 1 Limiting plates 23 are fixedly connected to both the front and rear sides above the surface of the grouting pipe 6. The inner wall of the limiting plate 23 is slidably connected to the surface of the support rod 3. A buffer spring 24 is sleeved on the surface of the support rod 3. The top end of the buffer spring 24 is fixedly connected to the bottom of the limiting plate 23, and the bottom end of the buffer spring 24 is fixedly connected to the top of the bearing plate 1.

[0029] As a technical optimization of this utility model, by setting a limiting plate 23 and a buffer spring 24, when the multi-stage electric telescopic rod 8 drives the grouting pipe 6 to move up and down, the limiting plate 23 slides on the surface of the support rod 3, and the buffer spring 24 follows the contraction and extension, which plays a role in positioning and reinforcing the grouting pipe 6, so that it can only move vertically up and down, and avoids the grouting pipe 6 from shaking and tilting during the lifting and lowering process, which would affect normal use.

[0030] refer to Figure 2 The bottom of the bearing plate 1 is fixedly connected to a positioning sleeve 25 that communicates with the grouting groove 7, and the bottom of the positioning sleeve 25 is fixedly connected to a rubber ring 26.

[0031] As a technical optimization of this utility model, by setting a positioning sleeve 25 and a rubber ring 26, the bottom height of the positioning sleeve 25 is the same as the bottom height of the hollow support leg 20. When the device moves above the pre-opened hole and is fixed, the rubber ring 26 fits against the surface of the pre-opened hole, protecting the area around the pre-opened hole, reducing the outflow of grout, and improving the grouting effect.

[0032] The working principle and usage process of this utility model are as follows: The device is moved above the mining area requiring repair, aligning the grouting groove 7 with the pre-drilled hole. Then, the multi-stage electric telescopic rod 8 is activated to retract, causing the grouting pipe 6 to move downwards. The output end of the grouting pipe 6 passes through the grouting groove 7 and inserts into the pre-drilled hole. The grout is then added to the grout tank 9 through the feeding hopper. The drive motor 10 is activated, causing the shaft 11 to rotate. As the shaft 11 rotates, it drives the stirring frame 12 and the stirring blades 13 to rotate, stirring the grout inside the grout tank 9 and improving its efficiency. The slurry is stirred until it reaches a certain fluidity. Then, the control valve 14 is opened to input the stirred slurry into the grouting pump 2. The grouting pump 2 delivers the slurry to the grouting pipe 6 for grouting the holes in the mining area. After grouting is completed, the control valve 14 and the grouting pump 2 are closed, allowing the multi-stage electric telescopic rod 8 to extend and the grouting pipe 6 to move out of the pre-drilled hole, thus enabling the device to move. This achieves continuous stirring of the slurry during the grouting process, effectively avoiding the problem of slurry solidification, ensuring good fluidity of the slurry, making the grouting process smoother, improving the grouting effect, and thus improving the quality of mining area restoration.
