[0040] The specific implementation process is as follows:

[0041] First, the rotating base 1 is installed on the workstation where it needs to be used by bolts, and then the rotating base 1 can rotate with the first driving device 2, and the first driving device 2 drives the swing arm 3 to swing, and the second driving device 4 at the upper end of the swing arm 3 can swing forward and backward. The second driving device 4 can swing the connecting arm 5, and the rotating device 6 at the front end of the connecting arm 5 can also swing. The rotating device 6 can rotate the auxiliary blowing device 7 connected to the bottom to adjust the blowing position;

[0042] When air blowing is needed, it is necessary to adjust the size of the workpiece to be blown and the blowing position, start the cylinder 7211 to work, and the left end of the cylinder 7211 extends during operation, which can lead the connecting plate 725 at the left end to slide on the guide rod 723 along with the slider. At the same time, due to the action of the connecting rod 727, the connecting rod 727 can pull the rotating member 728, and the rotating member 728 rotates. The connecting rod 727 at the other end follows the movement, and the connecting plate at the right end can follow the movement, so that the connecting plates 725 at both ends can move relative to each other, and the position between the blowing mechanism 73 and the collecting mechanism 74 at the bottom can be adjusted during the movement.

[0043] After adjustment, the air pipe 735 is connected to the external blowing equipment for air supply, and then the blowing is started. The air enters the air inlet bin 732 through the air pipe 735 and is blown out from the outlet bin 733 to start the blowing work. During the blowing process, the collection bin 742 facing the air can be exposed to the blown impurities and dust, and the impurities and dust enter the collection bin 742 through the filter 743 and are adsorbed by the adsorption cotton 744 in the collection bin 742. During the blowing process, the rotating device 6 can be started to work to perform surrounding blowing.

[0044] After the process is finished, when it is necessary to clean the impurities in the collecting bin 742 , apply force to pull the protrusion on the top of the collecting bin 742 out of the groove, then remove the filter screen 743 or the breathable net 745 at both ends, and then start replacing or cleaning the adsorption cotton 744 .

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
