Description

Technical Field

[0001] The utility model relates to the technical field of mine restoration, in particular to a mine restoration spraying device. Background Art

[0002] In the prior art, an important part of mine restoration is mine revegetation. Mine greening generally adopts a combined method of grass, shrubs and trees for the mining face, platform and slag heap. For revegetation on sloping mines, wire meshes need to be laid on the slope surface, and spraying is carried out on the slope surface to spray soil and grass seeds on the mine slope surface. After the grass seeds grow, the soil is solidified through the root systems and wire meshes, and through multiple regular sprayings, the soil layer on the slope surface is thickened, thus achieving the effect of slope revegetation. When some spraying equipment is used, the pre-mixed soil slurry and grass seeds are usually transported to the area to be sprayed, and then the mixed slurry is pumped out by a slurry pump and sprayed on the slope surface of the mine.

[0003] After retrieval, a patent with the Chinese patent application number 202222210944.4 discloses a mine restoration spraying device, which includes a vehicle body and a moving device arranged at the bottom of the vehicle body. An operation room is arranged on the vehicle body, and a mixing box is also arranged on the vehicle body. A mixing chamber is arranged inside the mixing box. The mixing box is provided with a feed inlet and a discharge outlet communicated with the mixing chamber, and a stirring mechanism is arranged inside the mixing chamber; it also includes a spraying assembly arranged on the vehicle body. The spraying assembly includes a mounting seat and a spraying pipe. A spraying head is arranged on the spraying pipe. The spraying pipe is connected with the discharge outlet through a spraying power mechanism. A rotating seat is rotatably arranged on the mounting seat, and a first driving assembly capable of driving the rotating seat to rotate is arranged on the mounting seat.

[0004] The above patent has the following deficiencies: Through the control of the first driving assembly and the second driving assembly, the spraying angle of the spraying head can be adjusted, so that the mixed slurry can be evenly sprayed onto the mine slope, improving the effect of mine restoration; however, the spraying pipe still needs to be manually controlled. When the spraying pipe is in the spraying process, it is not convenient to automatically adjust the spraying elevation angle of the spraying pipe. It is necessary to manually adjust the spraying elevation angle of the spraying pipe in advance before the spraying operation, and it is not convenient to quickly adjust the state of the spraying pipe according to the actual situation.

[0031] Between the spraying pipe 6 and the limit arc arm 8, there is a slurry pumping pump 7. The slurry pumping pump 7 is fixedly installed on the upper surface of the rotating top plate 5. And on the side of the slurry pumping pump 7 away from the spraying pipe 6, there is a slurry inlet pipe 20 fixedly connected. At the end of the slurry inlet pipe 20, there is a connecting pipe head one 21 fixedly installed, and the connecting pipe head one 21 is fixedly connected with an external slurry supply device through a pipeline.

[0032] At the top end of the slurry pumping pump 7, there is an outlet pipe 22 fixedly connected. At the top end of the outlet pipe 22, there is a connecting pipe head two 23 fixedly installed.

[0036] Working principle:

[0037] Please refer to Figures 1 to 3 to assemble this device as shown in the figure;

[0038] When this device is in use, first, install this device at a designated position or on a designated machine through the mounting base 1, and then connect to an external mud supply device through the connecting pipe head 1 and the pipeline; then start the slurry pumping pump 7, and spray the slurry mixed with vegetation seeds onto the surface of the mine through the spraying pipe 6; during the above process, the controller 35 controls the servo motor 11 to rotate forward and backward. Under the meshing transmission of the driving gear 12 and the arc-shaped tooth arm 32, the tooth arm mounting frame 33 drives the rotating top plate 5 to rotate forward and backward alternately and continuously inside the bearing ring frame 4, expanding the spraying range of the spraying pipe 6; at the same time, the controller 35 also controls the electric telescopic rod 29 to adjust the spraying elevation angle of the spraying pipe 6. As Figure 1 shown, at this time, the spraying pipe 6 is in a horizontal state. The electric telescopic rod 29 extends, and the spraying pipe 6 rotates around the rotating pin 1 as the rotation center. The spraying port of the spraying pipe 6 moves upward, and the spraying elevation angle increases. At this time, the spraying radiation area of the spraying pipe 6 increases; during the process of increasing the elevation angle, the rotating pin 1 drives the synchronous frame arm 16 to rotate synchronously through the connecting mounting rod 15, and the elastic energized copper sheet 17 moves along with the synchronous frame arm 16, thereby changing the energized length of the adapted energized resistor 18, that is, changing the resistance value of the slide rheostat. The larger the spraying elevation angle, the larger the resistance value of the slide rheostat, the smaller the on-flow current of the servo motor 11, the smaller the output rotation speed, and the smaller the rotation speed of the rotating top plate 5. In the case of a large spraying elevation angle of the spraying pipe 6, the slurry can be sprayed more evenly.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
