Description
Technical Field
[0001] This utility model belongs to the technical field of dust removal equipment, specifically relating to a dust removal equipment for engineering construction. Background Technology
[0002] Road construction is a crucial part of engineering projects. During stages such as roadbed excavation, backfilling, and pavement laying, extensive earthwork raises soil particles, creating a cloud of dust. The same applies to building demolition. Whether demolishing old buildings or modifying partial structures, broken bricks, concrete blocks, and other materials are turned into dust by machinery, filling the air. This dust poses multifaceted harms to the surrounding environment and residents. From an environmental perspective, dust significantly reduces air quality, darkening the sky and affecting the city's landscape and image. Over time, dust accumulates in soil and water, causing soil compaction, water pollution, and disrupting the ecological balance. For residents, dust is a "hidden killer" of health. Fine dust particles can enter the respiratory tract through respiration, causing respiratory diseases such as coughing, asthma, and bronchitis. Long-term exposure to high concentrations of dust can also lead to serious occupational diseases such as pneumoconiosis, severely threatening residents' health.
[0003] Currently, most existing dust removal equipment uses water mist spraying for dust suppression. While this method can reduce airborne dust concentration to some extent, the water mist can only cover a limited area due to the design and structural limitations of the nozzles. In large construction sites, effective dust removal across the entire area requires increasing the number of nozzles, which significantly increases equipment procurement costs. Furthermore, more nozzles require more water, increasing water consumption and potentially leading to water waste. Utility Model Content

[0009] A dust collection mechanism is provided on one side of the vehicle body. The dust collection mechanism includes a fan, a dust collection box is movably connected to one side of the fan, a filter screen is fixedly installed inside the dust collection box, a frame is fixedly installed on the outside of the fan, a column is fixedly installed on the outside of the dust collection box, the column is inserted into the frame, and a cover plate is movably installed on the outside of the fan, the cover plate is fitted to the top of the frame.
[0010] Preferably, the two U-shaped frames are symmetrically arranged at the top of the vehicle body. Each of the two U-shaped frames has a small turntable movably mounted on its top via a bearing. A swing rod is fixedly mounted on one side of the small turntable, and a nozzle is fixedly mounted on the end of the swing rod away from the small turntable.

[0011] Preferably, a rectangular plate is fixedly installed on one side of the top of the U-shaped frame, a servo motor is installed on one side of the rectangular plate via a fixed seat, a large turntable is movably installed on the top of the rectangular plate, the output end of the servo motor is connected to the shaft of the large turntable via a coupling, and a push rod is hinged between the large turntable and the short rod.
[0012] Preferably, a water tank is fixedly installed on the top of the vehicle body near the handrail, and a pump body is fixedly installed on the top of the vehicle body near the U-shaped frame. A water pumping pipe is connected between the pump body and the water tank, and a flexible hose is connected between the pump body and the nozzle.
[0013] Preferably, a column is fixedly installed on the top of the vehicle body away from the handrail, a fan is fixedly installed on the top of the column, a frame is fixedly installed on both sides of the fan, a limit rod is fixedly installed inside the frame, a column is fixedly connected to both sides of the dust collection box, a limit hole is opened inside the column, the column is sleeved on the outer wall of the limit rod through the limit hole, and the column slides against the inner wall of the frame.
[0014] Preferably, a sliding frame is fixedly installed on the side of the fan near the frame, a cover plate is inserted inside the sliding frame, damping is provided between the cover plate and the sliding frame, a sliding groove is opened at the top of the sliding frame, a slider is movably installed inside the sliding groove, the slider slides against the inner wall of the sliding groove, the side of the slider near the inside of the sliding frame is fixedly connected to the cover plate, and a pull block is fixedly installed on the side of the slider away from the cover plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) This utility model uses the cooperation of a large turntable, a push rod, and a short rod to drive a small turntable to rotate back and forth, thereby causing the nozzle at the end of the swing rod to swing left and right. This swing spraying method greatly expands the coverage of water mist, and can spray water mist evenly to a wider area, so that more dust in the air can come into contact with water mist and settle down, significantly improving dust removal efficiency. Through innovative structural design, a larger spraying range can be achieved without increasing the number of nozzles, effectively reducing equipment costs. At the same time, the reduction in the number of nozzles also reduces water consumption.
[0017] (2) This utility model adopts a combination of a fan and a dust collection box. The fan generates strong suction to draw dust from the air into the dust collection box. The filter effectively intercepts dust, preventing it from entering the fan. While ensuring the normal operation of the fan, it also deeply purifies the air. After being processed by the dust collection mechanism, the dust content in the air is further reduced. The dust collection and water spraying work together to form a highly efficient dust removal mode. The spraying mechanism first settles most of the dust, reducing the dust concentration in the air and lessening the burden on the dust collection mechanism. The dust collection mechanism then adsorbs the remaining fine dust, further removing dust from the air. The two work together, complementing each other's advantages, and greatly improving the overall dust removal effect.
[0018] (3) This utility model takes into account that the filter screen will be clogged with dust after long-term use, affecting the dust collection effect. Through the cooperation of the frame, limiting rod, column and limiting hole, the dust collection box can be quickly separated and assembled from the fan. The operator only needs to pull the cover plate away from the top of the frame to remove the column from the frame and clean or replace the filter screen. After cleaning or replacing, the column is reinserted into the limiting rod and the cover plate is closed to complete the assembly. This quick disassembly and assembly structure greatly shortens the time for cleaning and replacing the filter screen and ensures the normal operation of the dust collection mechanism and the dust collection effect.

[0033] The dust collection mechanism 3 is located on one side of the vehicle body 1. The dust collection mechanism 3 includes a fan 32. A dust collection box 33 is movably connected to one side of the fan 32. A filter 34 is fixedly installed inside the dust collection box 33. A frame 35 is fixedly installed on the outside of the fan 32. A column 37 is fixedly installed on the outside of the dust collection box 33. The column 37 is inserted into the inside of the frame 35. A cover plate 310 is movably installed on the outside of the fan 32. The cover plate 310 fits against the top of the frame 35.
[0034] Please see Figure 1 - Figure 4 As shown, specifically, two U-shaped frames 21 are symmetrically arranged at the top of the vehicle body 1. Small turntables 22 are movably mounted on the top of each U-shaped frame 21 via bearings. A swing rod 23 is fixedly mounted on one side of each small turntable 22.
