Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction, and specifically to a dust reduction device for highway engineering construction. Background Art

[0002] Highway engineering refers to the work of surveying, measuring, designing, constructing, maintaining, and managing highway structures. Highway engineering structures include subgrades, pavements, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening, and traffic monitoring facilities, as well as houses, workshops, and other service facilities used for construction, maintenance, and monitoring. During the construction process of highway engineering, various mechanical equipment is required to carry out operations such as excavation and transportation of rock and soil masses, which will generate a large amount of dust. This will not only pollute the surrounding environment but also endanger the physical and mental health of workers. Therefore, dust reduction treatment is needed to effectively purify the construction environment.

[0003] In order to carry out dust reduction, a fog cannon machine is generally used on-site for dust reduction operations. When the traditional fog cannon machine is in use, the adjustability of its fog cannon barrel is poor, and it is not convenient to adjust in multiple directions and at multiple angles according to actual needs. Moreover, due to the traditional fog cannon adopting a floating structure, the structure of the fog cannon is restricted, and at the same time, the fastening of the floating structure is insufficient, which is extremely likely to generate mechanical vibrations during use. This not only reduces the service life of the equipment but also generates extremely high mechanical noise, affecting the physical and mental health of workers. Summary of the Invention

The present invention fixes the entire device to the water tank truck by setting the positioning mounting seat 2, and connects the pressurized water supply component 43 to the water tank. At this time, the water in the water tank can be sucked and pressurized by the pressurized water supply component 43, and sprayed into the fixed air guide cylinder 9. In this process, the water-blocking component 44 is first rotated to prevent water droplets from falling into the blower component 42, which will corrode the blower component 42 and affect the service life of the equipment. In the present invention, the blower component 42 and the pressurized water supply component 43 are both relatively fixedly connected to the base 1. Compared with the traditional floating structure, the present invention has stronger stability, can effectively reduce the mechanical vibration generated during the operation of the equipment, reduce the mechanical noise generated during the operation of the equipment, and eliminate the structural limitations caused by the traditional structure. A higher-power motor can be installed to increase the mist output of the equipment, which can effectively increase the dust reduction speed of the equipment. At the same time, during use, the present invention can drive the gear 36 to rotate by driving the motor 5, and the gear 36 drives the first rotating cylinder 39, the second rotating cylinder 40, and the third rotating cylinder 41 to rotate respectively by mutual engagement with the outer gear ring 32. When the equipment needs to adjust the angle of the mist outlet 37 in the vertical direction, the first rotating cylinder 39 and the third rotating cylinder 41 are relatively fixed, and the second rotating cylinder 40 rotates relatively. At this time, the third rotating cylinder 41 is rotated and adjusted in the vertical direction under the drive of the second rotating cylinder 40. If the angle adjustment range is insufficient at this time, the first rotating cylinder 39 and the second rotating cylinder 40 can also be made to rotate synchronously, and the third rotating cylinder 41 and the fixed air guide cylinder 9 are relatively fixed. At this time, the two-stage adjustment of the angle of the mist outlet in the vertical direction can be achieved; At the same time, the horizontal angle of the mist outlet 37 can be adjusted by the synchronous rotation of the first rotating cylinder 39, the second rotating cylinder 40, and the third rotating cylinder 41; Furthermore, the present invention can continuously adjust the direction of the mist outlet 37 in a small range through the continuous rotation of the third rotating cylinder 41, so that the device can continuously spray into a larger conical airspace, which can effectively increase the dust reduction range of the device; When the fluid in the pipe reaches a certain speed, eddy currents and vortexes will be formed, thereby causing pipe vibration. Therefore, the present invention connects the suction cylinder 3, the first rotating cylinder 39, the second rotating cylinder 40, and the third rotating cylinder 41 in a relatively fixed manner, thereby reducing the mechanical vibration generated by the pipe. Meanwhile, since the air suction cylinder 3, the first rotating cylinder 39, the second rotating cylinder 40, and the third rotating cylinder 41 in the present invention are all of rigid structures, a sound-absorbing layer can be coated outside the air suction cylinder 3, the first rotating cylinder 39, the second rotating cylinder 40, and the third rotating cylinder 41, so as to effectively reduce the propagation of the noise generated by the gas flow, and further reduce the noise pollution generated during the operation of the equipment.
