The working principle is as follows:

the first step is as follows: the rotating drum 202 and the rotating disc 207 are driven to rotate by the driving action of the motor 201, because the left end of the first connecting rod 209 is inserted into the first groove 203, and the first connecting rod 209 is located at the connecting port of the first groove 203 and the second groove 204 in the initial state, when the rotating drum 202 rotates, the first connecting rod 209 moves forwards along the second groove 204, so that the fourth connecting rod 213 is driven to move forwards by the driving action of the second connecting rod 210 and the third connecting rod 212, the tray 216 fixedly connected with the fourth connecting rod 213 also moves forwards, so as to drive the ash cylinder 217 to move forwards, the scraper 218 fixedly connected with the upper end of the ash cylinder 217 can treat dust at the top of the electromechanical engineering workshop, the design structure of the scraper 218 can conveniently scrape dust at the top of the workshop, and accurately guide the scraped dust into the interior of the ash cylinder 217, and in the continuous rotation process of the rotating disc 207, due to the connection of the sixth connecting rod 215 and the fan-shaped groove 208, and the configuration of sector slots 208 includes a sector configuration, after tray 216 travels to the forefront, link six 215 just switches from one side of sector slots 208 to the other, completing a ninety degree flip in the direction of link five 214, tray 216 also undergoes a ninety degree flip under the connection of link four 213, link one 209 moves to the connection of slot three 205 and slot four 206 after the flip is completed, then as drum 202 continues to rotate, tray 216 moves back to the home position, then tray 216 reverses back at ninety degrees, allowing the overall cyclic motion operation of tray 216: and the dust scraping device moves forwards to the right to move backwards to the left, so that the dust scraping motion of the top of the workshop is completed.

The second step is that: through the existence of the second cross post 403, when the tray 216 is at the rearmost end, the first connecting rod 209 is also at the rearmost end, through the connecting action of the second cross post 403, thereby make the second cross post 403 promote the rearmost end of the first cross post 401 with the shift ring 404, thereby mesh together shift ring 404 and the first cross post 401 through the teeth of a cogwheel 402 and the teeth of a cogwheel two 405, like this under the drive of motor 201, the first cross post 401 rotates with rotary drum 202 simultaneously, thereby drive shift ring 404 and rotate, through the existence of belt 408, thereby make the cake 407 that changes also rotate, because it is in the same place with wheel 310 fixed connection through pillar 406 to change cake 407, thereby the drive arrangement carries out the removal to the right, thereby make ash cylinder 217 carry out the clearance of next row, the cooperation performance through cooperation device 4 has greatly improved device overall structure.

The third step: through the existence of the first vertical rod 304 and the second vertical rod 306, the bolt 308 is firstly screwed down from the outer side of the threaded column 305, at the moment, the threaded column 305 can easily perform vertical height adjustment under the manual assistance without being bound by the bolt 308, the appropriate height is adjusted up and down to adapt to the top height of an electromechanical engineering workshop with different heights, the height adjustment is the most appropriate that the scraper 218 is tightly attached to the wall surface, then the bolt 308 is screwed on the threaded column 305 again at the appropriate position, so that the bolt is accurately fixed, the height of the workshop is adapted by an adjusting device, and the adjustability of the device is greatly improved.

The fourth step: through the existence of protection device 3, urceolus 301 is as the main instrument of main collection electromechanical engineering workshop top dust, because the lightness of dust, the vibrations that produce also can be in the dust around urceolus 301 and shake when urceolus 301 collects the dust, through the existence of urceolus two 302 this moment, can collect these because vibrations and the dust that falls, avoid when clearing up the dust, most dust is shaken by the vibrations, guarantee that the inside machine in electromechanical workshop can not receive the pollution of roof dust, great improvement the safety in utilization of device.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
