[0023] The specific settings and functions of the adjusting device 3 and the limiting device 4 are described in detail below.
[0024] In this embodiment: an adjusting device 3 is provided on the surface of the base plate 1, and the adjusting device 3 includes a vertical rod 31, which is fixedly mounted on the surface of the base plate 1, a slide plate 32 is slidably connected to the surface of the vertical rod 31, and a bearing plate 33 is fixedly mounted on the side of the slide plate 32.
[0025] In this embodiment, the arrangement of the slide plate 32 and the vertical rod 31 enables the carrying plate 33 to move stably.
[0026] Specifically, two fixing plates 34 are fixedly installed on the surface of the bottom plate 1, a threaded rod 35 is rotatably connected between the two fixing plates 34, a rotating wheel 36 is fixedly installed on the surface of the threaded rod 35, and the threads on the surface of the threaded rod 35 are reverse threads with the rotating wheel 36 as the center.
[0027] In this embodiment, the setting of the rotating wheel 36 plays the effect of driving the threaded rod 35 to rotate.
[0028] Specifically, a slide bar 37 is fixedly installed between the two fixed plates 34, and two movable plates 38 are threadedly connected to the surface of the threaded rod 35. The movable plates 38 are slidably connected with the threaded rod 35 and the slide bar 37. A hinge plate 39 is hingedly connected to the surface of the movable plate 38, and one end of the hinge plate 39 away from the movable plate 38 is hingedly connected to the bearing plate 33. The setting of the hinge plate 39 has the effect of driving the bearing plate 33 to move.
[0029] In this embodiment: a limit device 4 is provided on the outer wall surface of the rotating column 5, and the limit device 4 includes a strip plate 41, which is fixedly installed on the outer wall surface of the rotating column 5, and a vertical groove 42 is opened on the surface of the strip plate 41, and a movable plate 43 is slidably connected inside the vertical groove 42, and a positioning rod 44 is fixedly installed on the surface of the movable plate 43, and a plurality of positioning holes 45 are opened in a ring on the surface of the supporting plate 33. When it is necessary to change the spraying direction of the spray pipe 9, first slide the sliding plate 48 to make the sliding plate 48 move inside the long groove 47. The movement of the sliding plate 48 inside the long groove 47 drives the movable plate 43 to move inside the vertical groove 42. The movement of the movable plate 43 inside the vertical groove 42 will squeeze the spring 46, so that the spring 46 is compressed. At the same time, the movement of the movable plate 43 inside the vertical groove 42 also drives the positioning rod 44 to move. The positioning rod 44 moves to move itself out of the positioning hole 45. The positioning rod 44 and the positioning hole 45 are separated to make the rotating column 5 lose the limit.

[0032] Working principle: by setting the adjustment device 3, when it is necessary to adjust the height of the spray pipe 9, first rotate the rotating wheel 36, and the rotation of the rotating wheel 36 drives the threaded rod 35 to rotate. Since the threads on the surface of the threaded rod 35 are mutually reverse threads with the rotating wheel 36 as the center, when the rotating wheel 36 drives the threaded rod 35 to rotate, the two movable plates 38 connected by threads on its surface will move in the direction of moving away from or approaching each other on the surface of the slide bar 37. The two movable plates 38 move in the direction of moving away from or approaching each other on the surface of the slide bar 37, driving the hinged plate 39 to move, the movement of the hinged plate 39 drives the bearing plate 33 to move, the movement of the bearing plate 33 drives the slide plate 32 to move on the surface of the vertical rod 31, and at the same time, the movement of the bearing plate 33 also drives the rotating column 5 to move, and the movement of the rotating column 5 drives the spray pipe 9 to move. When the spray pipe 9 moves When it moves to a suitable position, stop rotating the wheel 36. When the position of the spray pipe 9 is adjusted, start the water pump 12. The water pump 12 starts to transport the water inside the water tank 10 into the drain pipe 14 through the pumping pipe 13, and then transports the water from the drain pipe 14 into the spray pipe 9, and finally sprays it out from the spray pipe 9 to complete the corresponding dust reduction operation. During the spraying and dust reduction process of the spray pipe 9, when it is necessary to adjust the pitch angle of the spray pipe 9, start the motor 7. The motor 7 starts to drive the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the rotating plate 8 to rotate. The rotation of the rotating plate 8 drives the spray pipe 9 to rotate. The spray pipe 9 rotates to complete the adjustment of its pitch angle. Through the cooperation of the above-mentioned structure, the spray pipe 9 can be adjusted in height according to the stacking height of the sand and gravel pile, thereby improving the spraying and dust reduction effect of the device. When it is necessary to change the spraying direction of the spray pipe 9, first slide the sliding plate 48 to make the sliding plate 48 move inside the long groove 47. The movement of the sliding plate 48 inside the long groove 47 drives the movable plate 43 to move inside the vertical groove 42. The movement of the movable plate 43 inside the vertical groove 42 will squeeze the spring 46, so that the spring 46 is compressed. At the same time, the movement of the movable plate 43 inside the vertical groove 42 also drives the positioning rod 44 to move. The positioning rod 44 moves to move itself out of the positioning hole 45. The positioning rod 44 and the positioning hole 45 are separated to make the rotating column 5 lose the limit. At this time, the rotating column 5 can be rotated. The rotation of the rotating column 5 drives the spray pipe 9 to rotate. When the spray pipe 9 is rotated to the appropriate direction, the sliding plate 48 is released, and the rebound force of the spring 46 is used to re-insert the positioning rod 44 into the corresponding positioning hole 45, so as to re-limit the rotation of the rotating column 5.
