Description

Technical Field

[0001] The utility model relates to the technical field of spray devices, in particular to an earthwork vehicle-mounted dust-proof spray device. Background Art

[0002] Earthwork vehicle-borne transportation refers to the transportation of earth or stones by large trucks. The vehicle needs to generate strong power to transport the earth or stones due to the excessive gravity. However, during transportation, a lot of smoke and dust will be generated in the places where the vehicle passes, which will cause environmental pollution or be inhaled by pedestrians on the road, affecting their health.

[0003] For example, a vehicle-mounted environmentally friendly dust prevention device for earthwork disclosed in Chinese patent (CN202321822579.0) includes a fixed pipe, a three-way valve is installed at the bottom end of the fixed pipe, a second threaded sleeve is provided at the bottom connecting end of the three-way valve, a first threaded sleeve is provided at one connecting end of the three-way valve, a threaded connection port is threadedly installed at one end of the first threaded sleeve, a support pipe is installed at one end of the threaded connection port, a fixed shell is provided at one end of the support pipe, and a plurality of first dust removal nozzles are installed through one side of the fixed shell. In the utility model, dust removal liquid is sprayed out through the dust removal nozzle, so that when the truck is transported on the road, dust pollution to the environment is prevented. At the same time, the installation position of the dust removal nozzle can be installed on the first threaded sleeve and the second threaded sleeve through the threaded connection port, so as to realize installation in different directions, which can be selected according to the installation position.

[0004] The angle of the dust removal nozzle of the above-mentioned device is usually fixed during installation, and the angle of the dust removal nozzle cannot be adjusted. If the angle of the nozzle cannot be adjusted, the spray coverage may be insufficient, thereby affecting the dust prevention effect. The fixed-angle nozzle may cause partial waste of the spray, because the spray may be sprayed too much to areas that do not need to be cleaned, or the spray may be lost to the environment instead of covering the vehicle surface, limiting the flexibility and controllability of the spraying process. In view of the above problems, a dust prevention spray device mounted on an earthwork vehicle is proposed to solve them. Utility Model Content
