DETAILED DESCRIPTION
[0017] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a drilling machine 1, a handle 11, a driving shaft 12 and a drill bit 13, the side wall of the driving shaft 12 is fixedly connected with a plurality of fan blades 121, the side wall of the driving shaft 12 is slidably connected with a transparent shielding cover 2, the fan blades 121 do not contact the transparent shielding cover 2, the side wall of the transparent shielding cover 2 is provided with a plurality of through holes 21, the side wall of the transparent shielding cover 2 is fixedly connected with a dust collecting cover 3, the transparent shielding cover 2 is communicated with the internal space of the dust collecting cover 3 through the plurality of through holes 21, the side wall of the dust collecting cover 3 is fixedly connected with an interception ring network 31, one end of the drilling machine 1 is fixedly connected with a fixed plate 14, the driving shaft 12 is rotatably connected to the inner wall of the fixed plate 14, one end of the transparent shielding cover 2 is fixedly connected with a reset spring 22, and the reset spring 22 is fixedly connected to one side of the fixed plate 14.
[0018] In this embodiment: the drilling machine 1 is the driving body and supporting body of the device, the handle 11 is convenient for the operator to hold the drilling machine 1, the driving shaft 12 is the power output structure of the drilling machine 1, the driving shaft 12 is connected to the drill bit 13, and the driving shaft 12 is used to drive the drill bit 13 to rotate, so that the drill bit 13 can drill holes on the wall. After the transparent shielding cover 2 contacts the wall, it cannot move forward due to the reaction force of the wall. The transparent shielding cover 2 squeezes and shortens the return spring 22, and the fixed plate 14 supports the rear end of the return spring 22. The transparent shielding cover 2 shields the working area of the drill bit 13 from the outside, so that the smoke and dust generated when the drill bit 13 is working can be shielded by the transparent shielding cover 2. At the same time, the driving shaft 12 supports and drives a plurality of fan blades 121. When the fan blades 121 rotate, they generate a force to the drilling machine The airflow in direction 1 drives the smoke and dust inside the transparent shielding cover 2 to flow toward the drilling machine 1. The transparent shielding cover 2 releases the airflow and smoke and dust into the dust collecting cover 3 through a plurality of perforations 21. After the airflow and smoke and dust enter the dust collecting cover 3, the dust collecting cover 3 intercepts the smoke and dust with the interception ring network 31, and the air flow can be discharged through the interception ring network 31, so that the smoke and dust can be stored in the dust collecting cover 3, which is convenient for unified treatment of the smoke and dust, thereby realizing timely extraction of the smoke and dust, reducing the shielding effect of the smoke and dust on the working area between the drill bit 13 and the wall, and when the transparent shielding cover 2 is in contact with the wall, it can shield the smoke and dust, thereby preventing the smoke and dust from leaking out and posing a threat to the health of surrounding workers, thereby reducing safety hazards.
[0019] The side wall of the driving shaft 12 is rotatably connected to two shielding rings 122, and a number of fan blades 121 are located between the two shielding rings 122, and one of the shielding rings 122 is in contact with the inner wall of the transparent shielding cover 2; the two shielding rings 122 shield and protect the fan blades 121, and when the shielding ring 122 close to the drill bit 13 contacts the wall, the drill bit 13 reaches the maximum operating range, so the drill bit 13 cannot continue to go deeper, preventing the fan blades 121 from contacting the wall and causing damage, and the other shielding ring 122 close to the transparent shielding cover 2 blocks and limits the transparent shielding cover 2 to prevent the reset spring 22 from pushing the transparent shielding cover 2 to move excessively, resulting in the transparent shielding cover 2 contacting the shielding ring 122 and causing damage, thereby achieving a protective effect on the fan blades 121.
[0020] One end of the transparent shielding cover 2 is fixedly connected to a folding protective cover 23 for wrapping the reset spring 22, and one end of the folding protective cover 23 is fixedly connected to one side of the fixed plate 14; the folding protective cover 23 provides external shielding for the reset spring 22 and the drive shaft 12, reduces the impact of objects, dust, etc. in the external environment on the reset spring 22, reduces damage and oxidation corrosion of the reset spring 22, and increases the service life of the reset spring 22 and the drive shaft 12.
[0021] A plurality of blocking plates 24 are hinged on the side wall of the transparent shielding cover 2, and torsion springs are arranged between the blocking plates 24 and the transparent shielding cover 2, and the blocking plates 24 correspond to the positions of the through-holes 21 one by one; the blocking plates 24 block the corresponding through-holes 21, and the torsion springs drive the blocking plates 24 to flip toward the through-holes 21, so that the blocking plates 24 can block the through-holes 21 to prevent the dust entering the dust collecting cover 3 from flowing back into the transparent shielding cover 2, and when the fan blades 121 guide the airflow and smoke and dust, the airflow can push the blocking plates 24 to flip, so that the through-holes 21 can be opened, so that the dust and smoke can normally enter the dust collecting cover 3.
[0022] A blocking door 32 is provided on one side of the interception ring network 31, and the blocking door 32 is detachably connected to one side of the dust hood 3; the blocking door 32 cooperates with the interception ring network 31, and the interception ring network 31 and the blocking door 32 jointly intercept and filter the dust. When the dust retained in the dust hood 3 is processed, the connection between the blocking door 32 and the dust hood 3 is opened, so that the internal space of the dust hood 3 is exposed, and the dust inside the dust hood 3 can be discharged.
[0023] The working principle and use process of the utility model are as follows: when drilling a hole in a wall, the drilling machine 1 is controlled to drive the driving shaft 12 to rotate, and the driving shaft 12 drives the drill bit 13 to rotate, and the drill bit 13 and the transparent shielding cover 2 are in contact with the wall. After the transparent shielding cover 2 contacts the wall, it is unable to move forward due to the reaction force of the wall, and the transparent shielding cover 2 squeezes and shortens the reset spring 22, and the drill bit 13 drills into the wall. At the same time, the driving shaft 12 supports and drives a plurality of fan blades 121. When the fan blades 121 rotate, an airflow is generated in the direction of the drilling machine 1, and the airflow drives the smoke and dust inside the transparent shielding cover 2 to flow in the direction of the drilling machine 1, and then the airflow and the smoke and dust pass through The perforation 21 leads to the interior of the dust hood 3, and the dust hood 3 intercepts the smoke and dust through the interception ring network 31, thereby realizing the timely extraction of the smoke and dust, reducing the shielding effect of the smoke and dust on the working area between the drill bit 13 and the wall, and when the transparent shielding hood 2 is in contact with the wall, the smoke and dust can be shielded, thereby preventing the smoke and dust from leaking out and posing a threat to the health of surrounding workers, thereby reducing safety hazards. When the dust collected in the dust hood 3 is processed, the connection between the sealing door 32 and the dust hood 3 is opened, so that the internal space of the dust hood 3 is exposed, and the dust inside the dust hood 3 can be discharged.
