Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction fog cannons, in particular to a dust reduction mechanism for construction. Background Art

[0002] The fog cannon truck is also called a spray dust suppression truck, a multi-functional dust suppression truck, and a spray water sprinkler truck. It mainly relies on the spray unit on the rear working platform to work. It uses a high-pressure cannon barrel at an elevated angle to spray water mist into the air, forcing the polluted particles floating in the air to fall to the ground, so as to achieve the purpose of dust reduction, decomposition and dilution of dust in the air.

[0003] When the existing fog cannon vehicle is in use, a fan is installed on the back of the fog cannon vehicle to blow water mist, which can easily inhale external dust, causing dust to enter the fog cannon vehicle and cause blockage. At the same time, the dust will mix with the water mist and spray out, causing pollution to the water mist. For this reason, we propose a dust reduction mechanism for construction to solve the above problem. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-4 A dust reduction mechanism for construction includes a fog cannon vehicle base 1 and a fog cannon body 2. A driving fan blade 3 is installed inside the fog cannon body 2. The end of the fog cannon body 2 and the end of the filter bin 6 are connected to each other through a connecting flange 4 and a limiting bolt 5. The limiting bolt 5 can conveniently connect the two sets of connecting flanges 4, and facilitate the connection and installation between the fog cannon body 2 and the filter bin 6. A protective mechanism 7 is installed at the outer end of the filter bin 6, and a filter baffle 9 is fixedly connected to the inside of the filter bin 6, and a cleaning mechanism 8 is installed inside the filter baffle 9.

[0026] Further, see Figure 1 and Figure 2 It can be known that the protective mechanism 7 includes a limiting ring 71, the inner wall of the outer end of the filter bin 6 is fixedly connected to the limiting ring 71, and the surface of the limiting ring 71 is in contact with the mounting bolts 73, and a protective baffle 72 is inserted between the limiting ring 71 and the mounting bolts 73. The limiting ring 71 can facilitate the limiting installation of the mounting bolts 73.

[0027] Further, see Figure 2 and Figure 3It can be known that the cleaning mechanism 8 includes a driving column 81, and the driving column 81 is fixedly connected to the surface of the driving blade 3. A driven shaft 82 is installed inside the filter baffle 9 through a bearing. A recess that matches the driving column 81 is opened in the end of the driven shaft 82. Through the recess opened in the end of the driven shaft 82, the driven shaft 82 can be sleeved on the surface of the driving column 81, so that when the driving blade 3 rotates, the driving column 81 can drive the driven shaft 82 to rotate.

[0028] Further, see Figure 3 and Figure 4 It can be known that a screw hole is provided at one end of the driven shaft 82 away from the connecting stud 83, a driving rod 84 is inserted at the end of the driven shaft 82, and a connecting stud 83 is threadedly inserted between the driven shaft 82 and the driving rod 84. Through the screw hole provided at one end of the driven shaft 82, the connecting stud 83 can pass through the driving rod 84 and be connected to the screw hole, which can facilitate the limiting installation of the driving rod 84.

[0029] Further, see Figure 3 and Figure 4 It can be seen that the driven shaft 82 is set to be cylindrical, and a groove compatible with the driven shaft 82 is opened at the center position of the driving rod 84. Through the groove opened at the center position of the driving rod 84, the driving rod 84 can be easily sleeved on the end of the driven shaft 82.

[0030] Further, see Figure 3 and Figure 4 It can be known that a groove is provided inside the driving rod 84 , and a cleaning scraper 86 is welded to the inner wall of the groove through a push spring 85 . The groove provided inside the driving rod 84 can conveniently accommodate the cleaning scraper 86 .

[0031] Further, see Figure 3 and Figure 4 It can be known that one end of the cleaning scraper rod 86 inserted in the groove is fixedly connected to the limiting slider 87, and the inner wall of the groove is provided with a sliding groove adapted to the limiting slider 87. By telescoping and moving the cleaning scraper rod 86 in the groove, the limiting slider 87 can slide in the sliding groove, thereby playing the role of limiting and guiding the cleaning scraper rod 86.

[0032] Working principle: When the utility model is in use, when the fog cannon vehicle base 1 is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4, by passing the limiting bolt 5 through the connecting flange 4, the fog cannon body 2 can be connected with the inside of the filter bin 6. At this time, by driving the rotation of the fan blade 3, the air inside the filter bin 6 can be drawn into the fog cannon body 2 and blown out, so that the water mist can be sprayed out. At this time, the mounting bolt 73 can be connected to the limiting ring 71 through the protective baffle 72, and the air entering the filter bin 6 can be filtered through the mounting bolt 73 and the filter baffle 9. At the same time, when the fog cannon body 2 and the filter bin 6 are installed, the driven shaft 82 can be inserted into the surface of the driving column 81, so that when the driving blade 3 is rotated, the driving column 81 can drive the driven shaft 82 to rotate, and the driven shaft 82 drives the driving rod 84 to rotate along the surface of the filter baffle 9. By pushing the elastic force of the spring 85 itself, the cleaning scraper rod 86 can be kept in contact with the surface of the filter baffle 9, so that when the driving rod 84 is rotated, the cleaning scraper rod 86 can scrape off the filtered material on the surface of the filter baffle 9;

[0033] The above is the entire working principle of the utility model.
