Description

Technical Field

[0001] This utility model relates to the field of mine ecological restoration technology, and in particular to a mine restoration spraying device. Background Technology

[0002] During mining operations, large areas of exposed slopes (such as side slopes and mine walls) are often created. These areas have poor soil, loose structure, and are prone to soil erosion, landslides, and other geological disasters, severely damaging the regional ecological environment. Therefore, ecological restoration of exposed mine slopes has become one of the core tasks of mine environmental management. Among these methods, hydroseeding technology has become the mainstream approach for mine slope restoration due to its ease of operation and wide coverage. The principle involves mixing topsoil (soil improver), plant seeds, water-retaining agents, and fertilizers in a specific ratio to form a restoration material. This material is then sprayed onto the exposed slope using high-pressure hydroseeding equipment to form a stable vegetation growth layer.

[0003] However, existing mine restoration hydroseeding devices still suffer from poor adjustment flexibility in practical applications. The nozzle angles of existing hydroseeding devices are mostly fixed or manually fine-tuned, making it difficult to adapt to the complex and varied slope terrain of mines. This results in incomplete hydroseeding in some areas and poor uniformity of material coverage. Furthermore, most devices lack a retractable hydroseeding structure, which makes it impossible to flexibly adjust the hydroseeding distance when the slope is far away or there are obstacles, thus limiting the scope of operation.

[0004] Based on the above-mentioned technical problems, this utility model provides a mine restoration spraying device. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-2 This utility model provides a mine restoration hydroseeding device, comprising: Frame 1, on which drive wheels are mounted; Material bin 2 is fixed at the rear end of frame 1. A mixing component is installed inside material bin 2. A conveying pipe is installed at the bottom of material bin 2. A high-pressure pump and a pressure gauge are installed on the conveying pipe. An adjustment frame is installed at the front end of the frame 1. The adjustment frame includes a mounting frame 3, a deformation rod assembly, and a hydraulic tie rod 6. There are two sets of deformation rod assemblies, which are symmetrically hinged to the front side of the frame 1. The mounting frame 3 is hinged to the front end of the deformation rod assembly. The two ends of the hydraulic tie rod 6 are respectively hinged to the front end of the frame 1 and the mounting frame 3, and the hydraulic tie rod 6 is located between the two sets of deformation rod assemblies. The spraying mechanism consists of two sets, including a fixed pipe 4 and a telescopic pipe 5. The fixed pipe 4 and the telescopic pipe 5 are rotatably connected to the mounting frame 3. A control component is installed at the top of the fixed pipe 4 and is fixed to the end of the telescopic pipe 5 for adjusting the length of the telescopic pipe 5. The fixed pipe 4 and the telescopic pipe 5 are connected by a connecting pipe and the fixed pipe 4 is connected to the delivery pipe. High-pressure nozzles 7 are installed at the end of the telescopic pipe 5 and on the fixed pipe 4, respectively. A positioning component is installed on the side of the mounting frame 3 for controlling the angle between the fixed pipe 4 and the mounting frame 3. The control unit is used to operate the overall regulating device.

[0020] Before operation, the remediation materials, such as topsoil, plant seeds, water-retaining agents, and fertilizers, are added to the material bin 2 according to the specified proportions. The mixing component is activated by the control unit to thoroughly mix the materials and prevent stratification. After the materials are evenly mixed, the control unit activates the high-pressure pump on the conveying pipe to transport the materials in the material bin 2 to the spraying mechanism along the conveying pipe. At this time, the pressure gauge monitors the pressure in the conveying pipe in real time. If the pressure is abnormal, the control unit can adjust the output power of the high-pressure pump in time to maintain stable delivery. At the same time, according to the slope, height, and working distance of the mine slope, the control unit drives the hydraulic rod 6 of the adjustment frame. The extension and retraction of the hydraulic rod 6 causes the two sets of symmetrical deformation rod components to deform, thereby adjusting the overall height and front-back position of the mounting frame 3. Then, the angle between the fixed pipe 4 and the mounting frame 3 is adjusted by the positioning component on the side of the mounting frame 3 so that the high-pressure nozzle 7 on the fixed pipe 4 is aligned with the target slope area. Then, the extension length of the telescopic pipe 5 is adjusted by the control component at the top of the fixed pipe 4 to adapt to the spraying requirements of different distances on the slope. The high-pressure nozzles 7 of the two sets of spraying mechanisms spray materials synchronously. During the operation, the attitude of the adjustment frame, the spraying pressure and the length of the telescopic pipe 5 can be flexibly adjusted by the control unit. At the same time, with the help of the drive wheel movement device of the frame 1, the entire mine slope is sprayed evenly until the operation of the entire restoration area is completed.

[0021] Further optimization of the scheme: the mixing component includes a mixing motor, which is fixed on the top of the material box 2. The output end of the mixing motor is fixedly connected to a mounting shaft, and several stirring teeth are vertically and fixedly connected to the mounting shaft.

[0022] During operation, the control unit sends a start signal to the mixing motor, which (fixed to the top of the material bin 2) converts electrical energy into mechanical energy. drive The mounting shaft, fixedly connected to the output end, rotates at high speed. Since several stirring teeth are vertically fixed on the mounting shaft, its rotation causes the stirring teeth to move synchronously within the material bin 2. During this movement, the stirring teeth shear, tumble, and impact the materials such as topsoil, seeds, water-retaining agents, and fertilizers within the material bin 2. This breaks down the agglomeration of materials, preventing topsoil particle deposition, and promotes thorough mixing of different components, preventing issues such as seed concentration and water-retaining agent stratification. Ultimately, this provides uniformly composed remediation material for subsequent hydroseeding, ensuring consistent vegetation growth from the source.

[0023] Further optimization of the scheme: the control components include an adjusting motor 8, which is fixed on the fixed tube 4. The output shaft of the adjusting motor 8 is fixedly connected to a screw 9. The end of the telescopic tube 5 away from the mounting bracket 3 is fixedly connected to a fixed block 10. The screw 9 passes through the fixed block 10 and is threadedly connected to the fixed block 10. A limit block is installed at the end of the screw 9, and a limit ring is installed on the screw 9. The limit ring is used to limit the minimum length of the telescopic tube 5.

[0024] Since a fixing block 10 is fixed to the end of the telescopic tube 5 away from the mounting bracket 3, and the screw 9 is threadedly connected to the fixing block 10, the rotational motion of the screw 9 can be converted into the linear motion of the fixing block 10 (the reverse process of threaded transmission), thereby driving the telescopic tube 5 to extend or retract along the axial direction of the fixing tube 4 (the telescopic tube 5 extends when the screw 9 rotates forward and retracts when it rotates backward). At the same time, the limiting block at the end of the screw 9 can prevent the fixing block 10 from falling off the end of the screw 9, avoiding excessive extension of the telescopic tube 5 and resulting in structural damage; the limiting ring on the screw 9 can prevent the fixing block 10 from moving excessively towards the adjusting motor 8, limiting the minimum length of the telescopic tube 5, ensuring that the telescopic tube 5 always maintains an effective spraying length, and avoiding the high-pressure nozzle 7 from colliding with the mounting bracket 3 due to excessive retraction of the telescopic tube 5, thus achieving safety and accuracy in telescopic adjustment.

[0025] Further optimization of the scheme: the deformation rod assembly includes two parallel connecting rods 11, with the two ends of the connecting rods 11 hinged to the mounting frame 3 and the front end of the frame 1, respectively. The frame 1, the mounting frame 3 and the two sets of connecting rods 11 are arranged in a parallelogram structure.

[0026] When the hydraulic rod 6 extends and retracts to adjust the mounting frame, the thrust or pull of the hydraulic rod 6 acts on the mounting frame 3, causing the parallelogram structure to deform: the two sets of connecting rods 11 rotate synchronously around the hinge point, driving the mounting frame 3 to move smoothly in the vertical or horizontal direction (due to the constraint of the parallelogram structure, the mounting frame 3 always maintains a horizontal posture during the movement and will not tilt). This structural design avoids the problem of the mounting frame 3 shaking when adjusting the traditional adjustment frame, ensuring that the high-pressure nozzle 7 is always aligned with the target slope area when the height and front-to-back position of the spraying mechanism (installed on the mounting frame 3) changes, thus improving the spraying positioning accuracy.

[0027] The solution is further optimized. The positioning component includes a fixed arm 12, which is an L-shaped structure. One end of the fixed arm 12 is rotatably connected to the side of the mounting bracket 3 via a mounting seat, and the other end is rotatably connected to the side of the fixed tube 4. A locking bolt is vertically installed on the mounting seat. The locking bolt passes through the fixed arm 12 and is threaded with a locking nut. The locking nut abuts against the fixed arm 12.

[0028] When the spraying angle needs to be adjusted, loosen the locking nut (threaded connection to the locking bolt) to release the pressure constraint of the locking bolt on the fixed arm 12. At this time, the fixed tube 4 can be pushed to rotate around the mounting base. The fixed tube 4 drives the high-pressure nozzle 7 to adjust the angle synchronously (e.g., increase the nozzle elevation angle for steep slopes, and decrease the elevation angle for gentle slopes). After the angle is adjusted to the target position, tighten the locking nut so that the locking nut is in close contact with the side of the fixed arm 12. The rotation posture of the fixed arm 12 is fixed by friction, thereby locking the angle between the fixed tube 4 and the mounting bracket 3. This mechanical locking method is stable and reliable, and can avoid the spraying angle deviation caused by vibration during operation, ensuring that the high-pressure nozzle 7 always sprays materials at the preset angle, thus improving the accuracy of spraying coverage.

[0029] The solution was further optimized by installing a control valve on the delivery pipe.
