Automatic haze reducing apparatus for construction site

Abstract

The invention relates to the field of construction equipment and particularly provides an automatic haze reducing apparatus for construction site, which includes: a spray device, a pitching device, arotational device and a control device. The spray device includes a fog blowing mechanism and a liquid feeding mechanism. The pitching device includes a driving mechanism and a guiding mechanism. Therotational device includes a support platform and a rotary mechanism. The control device includes a controller and a sensor assembly electrically connected thereto. The apparatus can achieve stable rotation of the pitch angle of a T-shaped spray barrel for enlarging jet angle of the T-shaped spray barrel, so that the concentration of the fog is increased, and range of the T-shaped spray barrel isincreased. The pitching rotation and horizontal rotation precisions of the T-shaped spray barrel can be increased, so that toxic gas can be filtered off. The haze reducing apparatus can avoid omissionin a spray zone and is improved in utilization efficiency.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to an automatic haze reduction device for a construction site. Background technique [0002] On the construction site, the dust will be very large, and some harmful gases may be generated during the construction process, which is harmful to the human body. The existing dust removal and haze reduction machines can only clean the particles in the air to achieve the effect of haze reduction , and the spray angle of the existing dust removal and haze reduction machine cannot automatically adjust the spray angle in real time according to the spray area, making the efficiency of haze reduction low. [0003] In order to solve the above problems, a multi-angle rotating fog cannon machine with a patent number of CN201720812922.1 is disclosed. There is a water ring, and a ring of high-pressure nozzles is arranged on the water ring. There is also a water tank in the front of the housing,...

[0002] On the construction site, the dust will be very large, and some harmful gases may be generated during the construction process, which is harmful to the human body. The existing dust removal and haze reduction machines can only clean the particles in the air to achieve the effect of haze reduction , and the spray angle of the existing dust removal and haze reduction machine cannot automatically adjust the spray angle in real time according to the spray area, making the efficiency of haze reduction low

[0003] In order to solve the above problems, a multi-angle rotating fog cannon machine with a patent number of CN201720812922.1 is disclosed. There is a water ring, and a ring of high-pressure nozzles is arranged on the water ring. There is also a water tank in the front of the housing, and a water pump is also provided in the housing. The water inlet of the water pump is connected to the water tank. The body is rotatably connected with a mounting plate, the front end of the mounting plate is fixed with a fixed frame, the barrel is rotatably connected to the fixed frame, the top of the barrel end is rotatably connected with a first connecting rod, and the other end of the first connecting rod is rotatably connected with a The second connecting rod, the other end of the second connecting rod is connected with a pitching motor, and the pitching motor drives the second connecting rod to rotate, the gun barrel can automatically rotate under the drive of the rotating motor, and can be rotated at a certain angle The cyclical action of the raised hem, but the pitch angle range is small, and the gun barrel only rotates through one rotation axis. Its structure is not stable enough, and it cannot filter harmful gases in the air. Although the above structure can realize the horizontal rotation and pitch of the gun barrel Oscillation, but the control accuracy is not high
