Description

Technical Field

[0001] This utility model relates to the field of grouting and filling devices, specifically a grouting and filling device for coal mine goaf areas. Background Technology

[0002] A grouting and filling device for coal mine goafs is a piece of equipment used to fill goafs formed after coal mining. Its working principle involves adding grouting materials to a mixing tank in a specific ratio, where they are thoroughly mixed by a mixer to form a homogeneous slurry. Then, a grouting pump pressurizes the slurry and delivers it to the goaf through a pipeline. During the grouting process, the control system monitors parameters such as grouting pressure, flow rate, and slurry density in real time and adjusts them as needed to ensure the grouting effect. Current grouting and filling devices for coal mine goafs often use a single mixing paddle to agitate the grouting materials, which affects the mixing quality and efficiency of the slurry. Therefore, a new grouting and filling device for coal mine goafs is needed.

[0003] Existing grouting and filling devices for coal mine goafs have poor mixing efficiency in the grouting material, resulting in uneven grout formation and the presence of large particles, which affects the quality of the grout. Furthermore, they are inconvenient for the rapid installation of grouting pipes, making on-site assembly time-consuming and labor-intensive. Therefore, there is an urgent need for a grouting and filling device for coal mine goafs. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a grouting and filling device for coal mine goaf areas, so as to solve the problems of poor efficiency in mixing grouting materials and inconvenience in quickly installing grouting pipes in existing grouting and filling devices for coal mine goaf areas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grouting and filling device for coal mine goaf areas, comprising a mixing tank, a frame plate fixedly connected to the inner wall of the mixing tank, a drive motor fixedly connected to the top of the frame plate, a first rotating rod fixedly connected to the output shaft of the drive motor via a coupling, a main gear fixedly connected to the outer wall of the first rotating rod, a second rotating rod movably connected inside the frame plate, a first gear fixedly connected to the outer wall of the second rotating rod, a first stirring rod fixedly connected to the outer wall of the second rotating rod, a third rotating rod movably connected inside the frame plate, a second gear fixedly connected to the outer wall of the third rotating rod, and a second stirring rod fixedly connected to the outer wall of the third rotating rod.

[0006] A discharge pipe is fixedly connected to the outer wall of the mixing tank. A grouting pump is installed at one end of the discharge pipe. A connecting pipe is installed on the outer wall of the grouting pump. A clamp is fixedly connected to the outer wall of the connecting pipe. A grouting pipe is installed at one end of the connecting pipe. A sleeve is fixedly connected to the outer wall of the grouting pipe. A handle is movably connected inside the sleeve. A buckle is movably connected inside the handle.

[0007] Preferably, the main gear forms a rotating structure with the frame plate through the first rotating rod, and the main gear is meshed with the first gear.

[0008] Preferably, the main gear meshes with the second gear, and the first stirring rod forms a rotating structure with the frame plate via the second rotating rod.

[0009] Preferably, the second stirring rod forms a rotating structure with the frame plate via a third rotating rod, and the first stirring rod and the second stirring rod are arranged in parallel.

[0010] Preferably, the sleeve block forms a rotating structure with the handle via a pivot, and the handle forms a rotating structure with the buckle.

[0011] Preferably, the sleeve blocks are arranged in a ring around the central axis of the grouting pipe, and the buckles are engaged with the sleeve blocks.

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

[0013] 1. This utility model, through the configuration of a drive motor, a first rotating rod, a main gear, a second rotating rod, a first gear, a first stirring rod, a third rotating rod, a second gear, and a second stirring rod, allows the first rotating rod to rotate when the drive motor is started, thereby driving the main gear to rotate. Since the main gear meshes with the first gear and the second gear, the first gear and the second gear can rotate simultaneously, causing the first stirring rod fixedly connected to the outer wall of the second rotating rod to rotate. At the same time, the second stirring rod fixedly connected to the outer wall of the third rotating rod also rotates, which facilitates the uniform mixing of the grouting material and improves the efficiency of mixing the grouting material.

[0014] 2. This utility model, through the setting of a connecting pipe, a clamping block, a grouting pipe, a sleeve block, a handle, and a buckle, allows for quick installation of the grouting pipe by moving the grouting pipe to align with the connecting pipe, fastening the buckle onto the clamping block, and pressing down on the handle to rotate along the sleeve block, thereby tightening the buckle onto the clamping block. This facilitates quick installation of the grouting pipe and is more convenient and labor-saving than traditional flange connections. Attached Figure Description
