[0031] like Figure 4 and Figure 7 As shown, two outward-opening sliding grooves 108 are provided on the upper and lower end surfaces of the function disk 109 . The sliding grooves 108 are arc-shaped and symmetrically positioned.

[0032] Furthermore, a movable slider 107 is provided in the slide groove 108 , and a closed arc plate 106 is fixedly connected between the movable sliders 107 on the upper and lower sides, and the closed arc plate 106 is arc-shaped.

[0033] Furthermore, the collecting insert 112 is in a circular ring shape, and a collecting cavity 123 is provided in the collecting insert 112 , which is connected with each other from top to bottom. A hand-held plate 124 is fixedly provided on one side of the outer end surface of the collecting insert 112 .

[0034] like Figure 3 and Figure 5 As shown, a power shaft 121 is rotatably provided on the lower wall of the detection cavity 122 , the rotating column 113 is fixedly connected to the power shaft 121 , a rotating motor 120 is fixedly provided in the lower wall of the detection cavity 122 , and the lower end of the power shaft 121 is dynamically connected to the rotating motor 120 .

[0035] When the rotating motor 120 is started, it can drive the power shaft 121 to rotate, thereby driving the rotating column 113 to rotate.

[0036] Furthermore, a plurality of crushing blades 119 are rotatably connected to the lower side of the outer end surface of the rotating column 113, and the crushing blades 119 are arranged in a ring.

[0037] It should be noted that a rotating assembly is provided at the bottom of the rotating column 113 , and the rotating assembly can drive the crushing blade 119 to rotate. A spiral crushing blade is provided on the surface of the crushing blade 119 .

[0038] Furthermore, a circular connecting ring 118 is fixedly provided on the upper end surface of the mounting base plate 114 , and a downwardly opening mounting cavity 131 is provided on the lower end surface of the measuring device body 101 , and the mounting cavity 131 is mounted and connected to the connecting ring 118 .

[0039] Furthermore, a metal detector 132 is fixedly provided on the lower wall of the detection cavity 122 .

[0040] It is worth further explaining that the metal detector 132 is a metal detector in the prior art.

[0041] When working, first install the mounting base 114 under the measuring body 101 and connect it to the connecting ring 118 through the mounting cavity 131. At this time, the rotating column 113 is driven to penetrate into the crushing cavity 125, and the detection cavity 122 is connected to the crushing cavity 125.

[0042] When the installation work is completed, the collection plug 112 that has collected atmospheric dust is inserted into the functional disk 109 through the slot 104. After the collection plug 112 is completely inserted into the functional disk 109, the movable slider 107 is manually moved, and the movable slider 107 is driven to move along the guide groove 108, thereby driving the closed arc plate 106 to move, and move to the opening of the slot 104, and limit one end of the inserted collection plug 112 to prevent subsequent collection plugs 112 from falling.

[0043] Then, the telescopic connecting rod 102 is driven to move up and down repeatedly by the telescopic component in the telescopic connecting rod 102, thereby driving the functional disk 109 to move up and down repeatedly, and by driving the functional disk 109 to move up and down, the slot 104 is driven to move up and down to vibrate, and the fine particles of atmospheric dust collected on the surface of the slot 104 are separated. In this process, the rotating motor 120 is started and drives the power shaft 121 to rotate, thereby driving the rotating column 113 to rotate. At this time, the wind guide plate 105 is driven to rotate by the rotation of the rotating column 113, and the wind The guide plate 105 generates wind force and drives the wind force to flow upward, removing the fine particles of atmospheric dust through the airflow. When the initial fine particles are removed, the closed arc plate 106 is reset and the collection plug 112 is pulled out by holding the handheld plate 124. In the process of pulling out the collection plug 112, the remaining large particles of atmospheric dust fall downward into the guide cavity 111, and are guided by the internal guidance of the guide cavity 111 and the inclined wind guide plate 105, driving the retained particles of atmospheric dust downward through the crushing cavity 125 and falling into the detection cavity 122.

[0044] When large particles fall, the crushing blade 119 is driven to rotate by the rotating component, and the spiral crushing blade on the surface of the crushing blade 119 is used to rotate and crush the retained particles in the atmospheric dust. During this rotational crushing process, the non-metallic particles on its surface will be detached during the crushing work, and then the retained particles in the atmospheric dust will be crushed, which will facilitate the metal measurement of the metal meter 132 and further improve the metal measurement efficiency inside the retained particles in the atmospheric dust.
