Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, in particular to a dust reduction device for a trolley. Background Art

[0002] Building construction refers to production activities during the implementation phase of engineering construction, and is the construction process of various types of buildings. This process includes the design, construction, decoration and maintenance of buildings. During the construction process, in order to ensure the safety of workers and the quality of construction, corresponding protective measures need to be taken, such as setting up fences, isolation belts and warning signs. A large amount of dust will be generated during the construction process. These dusts will drift into the air and have adverse effects on the environment and human health. By taking dust reduction measures, the generation and dispersion of dust can be effectively reduced, and pollution to the environment can be reduced. Dust will affect the visibility of the construction site and reduce construction efficiency. Dust reduction measures can be taken to keep the construction site clean and tidy. Dust removal equipment is needed to deal with the dust on the construction site.

[0003] After searching, a Chinese new patent with publication number CN212818827U discloses a spray dust suppression device for construction sites. The invention aims to solve the problem that the existing automatic spray dust suppression machine is inconvenient to move due to the uneven construction ground during use, and the large vibration amplitude during movement causes the automatic spray dust suppression machine to be easily damaged, thereby reducing the service life of the automatic spray dust suppression machine. In addition, the existing spray devices all have a control panel to enable them to operate normally. The control panel needs to be waterproofed to prevent water from entering and causing damage to its internal circuits. However, the existing waterproof mechanism has poor waterproof effect and affects the operation. Therefore, the elastic buffering effect of the shock-absorbing spring on the upper side of the movable column is used to reduce the vibration of the main body of the spray dust suppression device when it moves on the uneven ground, and the universal wheel is used to facilitate the movement of the main body of the spray dust suppression device on the ground. The universal wheel is conveniently installed and fixed at the bottom end of the supporting leg, and the workload of the workers is reduced and the work efficiency of the workers is improved. The roller rolls on the surface of the movable column to reduce friction, prevent wear of the outer surface of the movable column, and extend the service life of the movable column.

[0004] There are still some shortcomings in the use of the above-mentioned dust reduction devices. Some existing dust reduction devices have more structures, are more complicated to operate, are less convenient to use, and have larger bodies and lower flexibility, making it difficult for the dust reduction devices to reduce dust in areas with narrow terrain during driving, which has a certain impact on actual dust reduction.
