The sawing machine cutting device, through the setting of the dust suction mechanism, operates the sawing machine cutting machine to cut metal pipe fittings, and a large amount of debris is generated during the cutting process. When the dust suction machine is in operation, dust is sucked through the dust suction pipe connected to the connecting sleeve, and a large amount of debris generated during the cutting process is sucked into the interior of the connecting sleeve through the bell mouth and the dust suction pipe, and is blocked by the filter plate to prevent the debris from entering the interior of the dust suction machine. When the debris inside the connecting sleeve needs to be cleaned, the collection box is pulled to slide the collection box out from the interior of the connecting sleeve, and then the debris inside the collection box is cleaned to prevent excessive debris from affecting the use of the device.

[0004] The above patent uses a vacuum cleaner to suck the debris to the filter plate, which then filters the debris. However, in actual use, the debris is easily clogged at the filter plate, which affects the normal filtering ability of the filter plate to the debris. Utility Model Content

The connecting piece 43 is rotatably connected to the scraper bar 41 through a rotating shaft. The scraper bar 41 is sleeved on the rotating shaft. When the scraper bar 41 rotates, it rotates around the rotating shaft. The side of the connecting piece 43 is in contact with the side of the scraper bar 41. After the electric push rod 42 is started, it drives the scraper bar 41 to move to scrape off the debris on the filter plate 32. The scraped debris enters the collection component 36 along the inclined tube 35.

[0028] Specifically, the filter plate 32 is inclined, and the angle between the filter plate 32 and the bottom of the inner wall of the box body 34 is thirty-five degrees.

[0029] In this implementation plan, please refer to Figure 3 The inclined filter plate 32 can increase the contact area between the airflow and the filter plate 32, thereby improving the filtering ability of debris in the airflow.

[0030] Specifically, the collecting assembly 36 includes a square box 361 fixed to the bottom of the inclined tube 35 , and a drawer 362 for collecting debris is slidably connected in the square box 361 .

[0031] In this implementation plan, please refer to Figure 3 The debris falling from the inclined tube 35 falls into the drawer 362 inside the square box 361, and the drawer 362 collects the debris scraped by the scraper 41 to prevent the debris from falling directly on the ground, thereby realizing centralized collection and processing of the debris, thereby facilitating the cleaning of the debris.

[0032] Specifically, the front and rear sides of the connecting member 43 are both fixed with limiting strips 44 , and the limiting strips 44 are attached to the side surfaces of the scraping strip 41 .

[0033] In this implementation plan, please refer to Figure 5 The contact area between the connecting member 43 and the scraper strip 41 is increased by the limiting strip 44 , thereby improving the limiting ability of the connecting member 43 on the scraper strip 41 .

[0034] Specifically, a guide block 46 is fixed to the end of the limiting strip 44 , and the guide block 46 is slidably connected to the inner wall of the box body 34 .

[0035] In this implementation plan, please refer to Figure 4 and Figure 5 When the limit bar 44 moves, it drives the guide block 46 to slide along the inner wall of the box body 34, thereby improving the guiding ability of the connecting member 43 and the scraping strip 41 during the movement, so that the connecting member 43 and the scraping strip 41 can move more smoothly.

[0036] Specifically, a triangular block 45 is fixed between the limiting strip 44 and the guide block 46 to improve the connection strength between the limiting strip 44 and the guide block 46 .

[0037] In this implementation plan, please refer to Figure 4 and Figure 5 The contact area between the guide block 46 and the limiting strip 44 is increased by the triangular block 45 , thereby improving the connection strength between the limiting strip 44 and the guide block 46 .

[0038] Specifically, a circular sleeve is fixed to the inner wall of the base 2 , and the inner wall of the circular sleeve is fixedly connected to the surface of the electric push rod 42 , so as to improve the fixing firmness of the electric push rod 42 .

[0039] In this implementation plan, please refer to Figure 3 The electric push rod 42 is further connected and fixed to the base 2 through the round sleeve, so that the fixing firmness of the electric push rod 42 is improved through the round sleeve.

[0040] The working principle and use process of the utility model: the operation of the centrifugal fan 31 allows the debris to enter the box body 34 through the suction head 33 and the suction pipe, and the air flow passes through the filter plate 32, and the debris is trapped on the upper side of the filter plate 32. The filtered air flow is discharged from the air outlet of the centrifugal fan 31;

[0041] The electric push rod 42 is started, the push rod of the electric push rod 42 is shortened and drives the connecting member 43 to move obliquely downward, and the connecting member 43 drives the scraping strip 41, the limiting strip 44 and the guide block 46 to move obliquely downward, and the connecting member 43 and the limiting strip 44 abut against the side position of the scraping strip 41 to prevent the scraping strip 41 from rotating when it moves obliquely downward, and the scraping strip 41 moves obliquely downward to scrape the debris on the filter plate 32, and the scraped debris falls into the drawer 362 in the square box 361 through the oblique tube 35, and the push rod of the electric push rod 42 is extended to drive the scraping strip 41 to move obliquely upward, and the connecting member 43 and the limiting strip 44 no longer abut against the scraping strip 41, so that the scraping strip 41 can rotate, and the scraping strip 41 can rotate when it moves obliquely upward, thereby preventing the debris from being scraped to the oblique upper position of the filter plate 32, and when the scraping strip 41 moves obliquely downward again, it is again abutted by the connecting member 43 and the limiting strip 44, so that the scraping of the debris on the filter plate 32 can be achieved;

[0042] After the debris in the drawer 362 is collected to a certain extent, the drawer 362 is pulled out from the square box 361 and the debris is poured out from the drawer 362, and then the drawer 362 is pushed into the square box 361 to continue collecting the debris.
