Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance, in particular to a road spraying device for highway maintenance. Background Art

[0002] Road maintenance is the upkeep and maintenance of roads. Maintain roads and structures and facilities on them, keep road performance as good as possible, restore damaged parts in time, ensure safe, comfortable and smooth driving, save transportation costs and time; take correct technical measures to improve project quality, extend the service life of roads, and postpone reconstruction time. Water spraying is a common maintenance method in road maintenance.

[0003] During the road maintenance process, a large amount of dust is easily generated. In order to prevent air pollution, dust reduction spraying devices are needed to carry out dust reduction treatment.

[0004] However, in the process of road maintenance, due to the different widths of roads, if only one nozzle is used for spraying, not only will the dust reduction efficiency be low, delaying the subsequent road cleaning time, but it will also fail to fully complete the dust reduction work on the left, right, front and back of the road, making it inconvenient for road cleaning and environmental protection. Utility Model Content

[0005] The purpose of the utility model is to provide a road spraying device for highway maintenance, which is used to overcome the above-mentioned defects in the prior art.

[0006] According to the utility model, a road spraying device for highway maintenance includes a vehicle body, the upper end of the vehicle body is fixedly provided with two air supply boxes distributed on the left and right, the opening of the air supply box is arranged backward, a water frame is fixedly embedded in the rear end opening of the air supply box, water pipes evenly distributed on the left and right are connected to the water frame, and atomizing nozzles evenly distributed up and down are arranged at the rear end of the water pipe, a water tank is fixedly provided on the upper end surface of the vehicle body, the water tank and the water frame are connected to a liquid pump through a pipeline, and two left-right symmetrical baffles are hingedly provided at the rear end of the air supply box, and an elastic partition plate evenly distributed up and down is arranged between the two baffles. A fixed box is fixedly provided at the upper end of the box, and a power motor is fixedly provided on the fixed box. A bidirectional screw is connected to the power motor for power connection. Two groups of left-right symmetrical slider groups are threadedly connected on the outer periphery of the bidirectional screw. Two left-right symmetrical bidirectional threads are provided on the outer periphery of the bidirectional screw. A sliding groove is provided at the lower end of the baffle. A guide slider is rotatably connected to the upper end of the slider group to slide in the sliding groove. A dustproof net is fixedly embedded on the front end surface of the air supply box. A filter net and a fixed plate are fixed in the air supply box. The fixed plate is located at the upper end of the filter net, and an air supply mechanism is connected to the fixed plate.

[0007] The beneficial effects of the utility model are:

[0008] Through the arrangement of atomizing nozzles, baffles, elastic partitions and air supply mechanisms, when carrying out highway spraying maintenance work, while the vehicle body is moving forward, spraying maintenance work is carried out on the road behind through the air supply boxes distributed on the left and right. The air supply mechanism in the air supply box can enhance the spraying distance and spraying range of the atomized liquid through wind force after the atomized liquid is sprayed out from the water pipe and the atomizing nozzle, thereby adapting to highway maintenance in different environments.

[0009] The movement of the slider group is controlled by a power motor to change the angle between the two baffles, thereby changing the coverage of the atomized liquid diffusion driven by wind, further increasing the diffusion range of the atomized liquid and thus enhancing the adaptability of the device.

[0024] The user controls the vehicle body 10 to move on the road. During the movement, the liquid pump at the water tank 12 extracts the liquid stored in the water tank 12, and transmits the liquid to the water frame 17 through the pipeline.
