[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2As shown, the utility model includes a sprayer 1, a lifting assembly 2, a walking assembly 3, a pillar 4 and a dust monitoring device 6; the pillar 4 is arranged along one side or both sides of the material field, and at least two pillars are arranged; the lifting assembly 2 is composed of a winch 2-1 and a lifting slider 2-2, and a guide groove matching the lifting slider 2-2 is arranged on the pillar 4, and the winch 2-1 is arranged on the top of the pillar 4, and its traction rope 2-1-1 is connected to the lifting slider 2-2; the sprayer 1 is installed on the track 5 through the walking assembly 3, and the track 5 is installed on the lifting slider 2-2; the number of the dust monitoring devices 6 is not less than 3, and they are dispersed in the material field. In order to facilitate the lifting slider 2-2 to slide up and down, a roller matching the guide groove can be installed on the slider.

[0018] For a rectangular material field, the support 4 can be set along one side or two sides of the material field according to the width of the material field and the spraying distance of the sprayer; for a square material field, the support 4 can be set along two sides or four sides of the material field. The dust monitoring device 6 can use VEMSEERS485 series dust sensors or other brands and models.

[0019] The winch 2-1 can also be replaced by a hoist for lifting the sprayer.

[0020] The walking assembly 3 is used for the sprayer to walk along the periphery of the material field, and the following scheme can be adopted: the walking assembly 3 is composed of a frame 3-1 and a walking wheel 3-2 arranged thereon, the track 5 is I-shaped and matches the walking wheel 3-2, the frame 3-1 is suspended below the track 5 through the walking wheel 3-2, the bottom surface of the track 5 is provided with a rack 5-1, and the frame 3-1 is also provided with a gear 3-3 matching the rack 5-1, and the gear is driven by a driving motor 3-4. The I-shaped track is installed below the lifting slider 2-2, and is composed of an upper crossbeam, a middle vertical beam and a lower crossbeam. There are two walking wheels 3-2 that match the planes on both sides of the lower crossbeam and are in rolling contact. The walking assembly 3 can also be arranged above the track 5, and the corresponding sprayer is also arranged above the walking assembly.

[0021] The height of the spraying angle of the sprayer determines its range, so the following scheme can be adopted to add the adjustment of the spraying height and left and right directions: a rotating platform is arranged below the frame 3-1, a boom is arranged below the rotating platform, the sprayer 1 is hinged on the boom, an electric cylinder 7 is arranged between the sprayer 1 and the rotating platform, and the two ends of the electric cylinder 7 are respectively hinged to the sprayer 1 and the rotating platform. The rotating platform can be an electric rotating platform, or a motor-driven gear set, the motor drives the active gear to drive the passive gear to rotate, and the passive gear is connected to the platform to realize rotation.

[0022] The sprayer can also be selected to adjust the spray height and left and right directions. If only the height adjustment mechanism is set, the boom can be directly connected to the bottom of the frame 3-1, and the electric cylinder 7 is set between the sprayer 1 and the frame 3-1; if only the direction adjustment is set, the sprayer 1 can be directly installed on the rotating platform.

[0023] The electric cylinder 7 may also be replaced by a hydraulic cylinder.

[0024] In order to realize automatic spraying according to the dust situation, the following scheme is adopted: the system also includes a CPU and a control circuit; the output of the dust monitoring device is connected to the input end of the CPU, and the output end of the CPU is respectively connected to control the drive motor 3-4, the sprayer 1, the winch 2-1 and the electric cylinder 7 and the drive motor of the rotating platform. The output end of the CPU can control the above-mentioned electrical equipment by connecting the three-stage tube amplifier circuit at the output end of the CPU, connecting the collector or emitter of the three-stage tube to the circuit breaker, and connecting and controlling the above-mentioned electrical equipment through a relay. The axial flow fan, high-pressure water pump, and high-pressure air pump in the sprayer can be controlled by a relay separately, or they can be synchronously controlled as a whole through a relay. The winch 2-1 is an electric winch. The CPU can use the C8051F340 series chip, the 8051F340-GQR model of the SILICON LABS brand, and the number of its input / output terminals is 40, which can meet the needs.

[0025] In automatic spraying, the sprayer needs to automatically identify when it reaches the end of the track. The following solution can be adopted: along the movement direction of the frame 3-1, laser ranging sensors are set at its front and rear ends, and reflective plates matching the laser ranging sensors are set at the head and tail of the track 5. The reflective plates are steel plates or other metal plates to facilitate laser reflection during distance measurement; the output signal of the laser ranging sensor is connected to other input terminals of the CPU. For larger material yards, 2-3 or more groups of walking components can be set on a single track 5 according to the length of the material yard, and the same number of sprayers are set accordingly.

[0026] By setting up a dust monitoring device, a laser distance sensor, a CPU and a control circuit, the CPU controls the drive motor to drive the sprayer to move, the winch to drive the sprayer to rise and fall, and controls the sprayer to spray in the direction of spraying according to the installation position of the dust monitoring device. According to the dust position detected by the dust monitoring device, the laser distance sensor determines the position of the sprayer, and the CPU controls the drive motor to drive the sprayer to move horizontally on the track to a position that is easy to remove dust; according to the distance between the dust position and the track, the sprayer is controlled to pitch to a fixed action or to do reciprocating pitch spraying, and similarly, the sprayer is controlled to rotate left and right to adjust the spray direction.
