Description

Technical Field

[0001] This invention relates to the field of coal mine construction technology, specifically to a coal mine filling and grouting device that is easy to move. Background Technology

[0002] Easily portable coal mine filling and barrier grouting devices are core equipment in the field of coal mining and safety support. Their core function is to quickly construct filling and barrier structures in underground goaf areas, roadway sidewalls, or around working faces.

[0003] The device mainly consists of a mobile chassis, a storage tank, a mixing system, a high-pressure pumping unit, a pouring spray gun, a hydraulic drive module, and a control panel. The mobile chassis transports the device to the target work point. The filling material in the storage tank is kept uniform by the mixing system. The high-pressure pumping unit pressurizes the material and delivers it to the pouring spray gun through pipelines. The operator adjusts the parameters through the control panel to accurately pour the material into the preset area, quickly forming a solidified barrier structure.

[0004] However, the above-mentioned equipment has certain shortcomings in use. Traditional devices mostly use a single propeller or stirring rod, which can only achieve local material turning and then direct pouring. Small lumps that are not broken up are easy to enter the material conveying channel, resulting in honeycomb-like pores in the pouring layer. In view of this, we propose a coal mine filling and partitioning pouring device that is easy to move. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a coal mine filling and grouting device that is easy to transfer, and has the following beneficial effects: 1. This easily portable coal mine filling and grouting device is equipped with a mixing component to adapt to batch operations of coal mine filling and grouting. During the mixing stage, this component, in conjunction with a servo motor, drives a long rod and an auxiliary auger paddle to rotate clockwise, lifting the material at the bottom upwards and forming a mixing mode with the vertical tumbling of the spiral mixing drum, thoroughly breaking up lumpy materials. During the grouting stage, the servo motor switches direction to drive the auxiliary auger paddle to rotate counterclockwise, powerfully pushing the material downwards to prevent material stagnation. The power motor drives the conical auger rod to output the material in the temporary storage bin through the conveying pipe. The movable base facilitates flexible transfer of the device, adapting it to different underground operating points.

[0017] 2. This easily portable coal mine filling and grouting device, in order to adapt to the continuous operation requirements of the complex underground coal mine environment, is equipped with an auxiliary component. This component, in conjunction with the drive gear and transmission gear, drives the short rod and auger blades to rotate. The auger blades located below the discharge pipe intercept a small amount of undissolved clumps to avoid clogging the material conveying channel. When the auxiliary auger paddle discharges material counterclockwise, the auger blades rotate synchronously to assist in guiding the material, making the material flow smoother. Multiple sets of auger blades perform secondary mixing of the material in the temporary storage bin, which, together with the mixing paddle driven by the auxiliary motor in the mixing bin, enhances the mixing effect.

[0018] 3. This easily portable coal mine filling and grouting device is equipped with a protective component to adapt it to high-frequency grouting operations in underground coal mines. This component, along with the ball on the mounting ring, rolls against the inner wall of the mounting cylinder. With the elastic support of the spring, it effectively reduces the radial runout of the long rod and avoids shaft wear, regardless of whether the auxiliary auger paddle rotates clockwise or counterclockwise. The inclined guide plate guides the material fed into the inlet to be evenly dispersed into the mixing chamber without impacting the long rod, the spiral mixing cylinder, or the auxiliary auger paddle.

The mixing chamber 31 is connected to the internal space of the temporary storage chamber 310 through the discharge pipe 38. The straight rod 315 penetrates the outer wall of the temporary storage chamber 310. The conical auger rod 316 is located inside the temporary storage chamber 310 and the conical conveying chamber 311.

[0025] In this embodiment, before operation, the device is moved to the target operation point in the coal mine by moving the base 2, and the filling material is put in from the feed inlet 32. Entering the mixing stage: Start the servo motor 34 on the mounting cylinder 33 to drive the long rod 35 to rotate clockwise, which drives the spiral mixing cylinder 36 and the auxiliary auger paddle 37 to rotate synchronously. The auxiliary auger paddle 37 lifts the material at the bottom of the mixing chamber 31 upwards, and the spiral mixing cylinder 36 vertically tumbles the material to form a "lifting + tumbling" mixing mode, which thoroughly breaks up the clumps of material and ensures uniform mixing. After mixing, the pouring stage begins: the servo motor 34 switches direction, driving the long rod 35 and auxiliary auger paddle 37 to rotate counterclockwise, forcefully pushing the material in the mixing chamber 31 downwards to prevent material stagnation; the solenoid valve 39 on the discharge pipe 38 is opened, and the material is transported to the temporary storage chamber 310 through the discharge pipe 38; the power motor 314 on the mounting plate 313 is started, driving the straight rod 315 to rotate the conical auger rod 316, pushing the material in the temporary storage chamber 310 to the conical conveying chamber 311, and finally output through the conveying pipe 312, completing the coal mine partition pouring operation; the support pad at the bottom of the conical conveying chamber 311 enhances structural stability and prevents displacement caused by underground bumps.

The driving gear 42 meshes with the transmission gear 44. The short rod 43 is rotatably installed on the limiting cylinder 41. The auger blade 45 is set inside the temporary storage chamber 310. One set of short rods 43 and auger blade 45 is set directly below the discharge pipe 38.

[0027] In this embodiment, when the power motor 314 is running, the drive gear 42 on the straight rod 315 drives the meshing transmission gear 44 to rotate, which in turn drives the short rod 43 and the auger blades 45 to rotate synchronously. The limiting cylinder 41 fixes the position of the short rod 43 to ensure stable transmission. One set of auger blades 45 located directly below the discharge pipe 38 can intercept a small amount of undissolved lumps conveyed from the mixing chamber 31 to avoid clogging the material conveying channel. When the auxiliary auger paddle 37 discharges material counterclockwise, this set of auger blades 45 rotates synchronously to assist in guiding the material, making the material flow smoother. At the same time, multiple sets of auger blades 45 rotate in the temporary storage chamber 310 to perform secondary mixing of the material, further improving the mixing uniformity. The auxiliary motor 47 on the tripod 46 is started to drive the round rod 48 to drive the mixing paddle 49 to rotate. It works in conjunction with the spiral mixing drum 36 and the auxiliary auger paddle 37 in the mixing chamber 31 to enhance the mixing effect, ensure the stability of the filling material performance, and adapt to the continuous grouting needs of the complex environment in underground coal mines.

[0028] In one embodiment of the present invention, a protective component 5 is provided on the mixing chamber 31. The protective component 5 includes a mounting ring 51, which is fixedly mounted on a long rod 35. A cylinder 52 is fixedly mounted on the mounting ring 51. One end of a spring 53 is fixedly mounted inside the cylinder 52. One end of a support rod 54 is fixedly mounted on the other end of the spring 53. A ball 55 is hinged to the other end of the support rod 54. A partition 56 is fixedly mounted inside the mounting cylinder 33. An inclined guide plate 57 is fixedly mounted inside the mixing chamber 31. Multiple sets of cylinders 52, springs 53, support rods 54, and balls 55 are provided. The mounting ring 51, cylinders 52, springs 53, support rods 54, and balls 55 are disposed inside the mounting cylinder 33. The balls 55 are attached to the inner wall of the mounting cylinder 33.

The inclined guide plate 57 is directly opposite the feed inlet 32.

[0029] In this embodiment, when the long rod 35 rotates, the mounting ring 51 rotates synchronously, causing the cylinder 52, support rod 54, and ball 55 to move together. The ball 55 rolls against the inner wall of the mounting cylinder 33, reducing the radial runout of the long rod 35. The spring 53 inside the cylinder 52 provides elastic support, which can buffer the vibration generated when the long rod 35 rotates, avoid shaft wear, and extend the service life of the servo motor 34 and the long rod 35. At the same time, when materials are fed into the feed port 32, the inclined guide plate 57 inside the mixing chamber 31 guides the materials to be evenly distributed to various areas inside the mixing chamber 31, avoiding concentrated impact of materials on the long rod 35, spiral mixing cylinder 36, and auxiliary auger paddle 37, and preventing damage to the components. The partition plate 56 separates the internal space of the mounting cylinder 33, preventing materials from entering the protective component 5 and ensuring smooth rolling of the ball 55.
