When operating, the machine body 1 is first installed at a location with more dust, and the air and dust are extracted through the operation of the air inlet hood 2, and then transported to the inside of the machine body 1 for filtering.

[0046] In the embodiment of the present invention, specifically, both sides of the interior of the machine body 1 are rotatably connected with a transmission shaft 501, and a filter screen 5 is rotatably connected between the two transmission shafts 501, and the filter screen 5 is used to filter dust in the air. A filter plate 101 is fixedly installed inside the machine body 1, and the filter plate 101 is used to perform secondary filtering on the air. When the air enters the interior of the machine body 1, the dust in the air can be filtered through the setting of the filter screen 5 until the filtered air is discharged after secondary filtering through the filter plate 101;

[0047] Furthermore, the cleaning shaft 8 is rotatably connected to the inside of the machine body 1, and a plurality of elastic plates 801 are fixedly installed on the outside of the cleaning shaft 8. The installation position of the cleaning shaft 8 is located inside the filter 5, and is used to beat the running filter 5 through the plurality of elastic plates 801 to make the dust attached to its surface fall off. When the filter 5 filters the dust in the air, the filter 5 can be driven to run inside the machine body 1 as the transmission shaft 501 rotates to ensure the filtering effect. At the same time, when the filter 5 is running, the cleaning shaft 8 rotates, which can drive the elastic plates 801 to rotate, beat the filter 5, and make the dust attached to the surface of the filter 5 fall off.

[0048] Specifically, a bottom sealing plate 10 is provided at the bottom of the machine body 1, a waste discharge slot 1001 is provided on one side of the bottom sealing plate 10, and a lower hopper 11 is fixedly installed below the waste discharge slot 1001, and a sealing rotating plate 13 is rotatably connected inside the lower hopper 11, which is used to discharge the deposited dust through the rotation of the sealing rotating plate 13, and as the elastic paddle 801 knocks off the dust attached to the surface of the filter screen 5, the dust can pass through the waste discharge slot 1001 and fall into the lower hopper 11;

[0049] Specifically, during the dust collection process, the sealing rotating plate 13 is in a horizontal state, sealing the lower hopper 11, referring to Figure 5 , Figure 6 On the one hand, the sealing of the machine body 1 is ensured to better collect dust, and at the same time, it can prevent air from being discharged through the lower hopper 11, causing the collected dust to float here with the air;

[0050] Specifically, a weight sensing module is provided inside the sealing rotating plate 13 to sense the weight of the dust accumulated above. When the weight reaches a certain value, the sealing rotating plate 13 rotates so that the collected dust can be automatically discharged through the lower hopper 11, further ensuring the dust control effect;

[0053] Specifically, when the sealing rotating plate 13 is in a horizontal state to block the lower hopper 11, during the process of filtering the air, the blocking slide plate 12 can be in a state of being retracted into the limiting slide groove 1002, and the dust can fall through the waste discharge slot 1001. When the sealing rotating plate 13 rotates to perform dust discharge operation, the transmission plate 1202 is affected by the wind pressure and can drive the blocking slide plate 12 to slide in the direction of the waste discharge slot 1001 until the waste discharge slot 1001 is blocked.

[0054] Specifically, when the dust discharge is completed, the sealing rotating plate 13 rotates to a state where the lower hopper 11 is blocked. At this time, the sealing air cannot pass through the waste discharge end of the machine body 1, so that the wind pressure on the transmission plate 1202 is reduced, and the blocking slide plate 12 can be reset through the elastic pull rope 1201 and retracted into the limiting slide groove 1002, so that the waste discharge slot 1001 is reopened, and an automatic waste discharge process is completed;

[0055] Specifically, a plurality of elastic pull ropes 1201 are fixedly installed between the end of the blocking slide plate 12 and the inner wall of the limiting slide groove 1002, and are used to drive the blocking slide plate 12 to reset when the sealing rotating plate 13 rotates to close the lower hopper 11;

[0056] Specifically, the interior of the bottom sealing plate 10 is provided with an inclined surface, and the waste discharge slot 1001 is provided at a lower end of the inclined surface, so that the deposited dust can be discharged through the waste discharge slot 1001. When the equipment is running, vibration can be generated, so that the dust falling on the bottom sealing plate 10 can enter the waste discharge slot 1001 along the inclined surface, thereby further realizing the dust collection operation;

[0059] Specifically, a cleaning scraper 1203 is fixedly installed on one side of the end of the blocking slide 12 away from the transmission plate 1202. The cleaning scraper 1203 is in contact with the inner wall of the body 1 and is used to clean the inner wall of the body 1. The cleaning scraper 1203 is used to scrape off the dust attached to the inner wall of the body 1 as the blocking slide 12 runs.

[0060] Specifically, the side of the transmission sheet 1202 close to the inner wall of the body 1 is in contact with it, and is used to scrape off the dust attached to the inner wall of the body 1 during operation. A distance is left between the side of the transmission sheet 1202 close to the filter screen 5 and the filter screen 5 to prevent the filter screen 5 from contacting the transmission sheet 1202 during operation, thereby preventing dust from entering the waste discharge end of the body 1.

[0061] Specifically, the waste discharge end of the body 1 refers to the end where the waste discharge slot 1001 provided on the bottom sealing plate 10 is located;

[0062] Specifically, a positioning frame 3 is fixedly installed inside the air inlet cover 2, and a rotating shaft 301 is rotatably installed inside the positioning frame 3, and an arc-shaped blade 302 is fixedly sleeved on the outer side of the rotating shaft 301; an air inlet drive motor 4 is fixedly installed on the top surface of the air inlet cover 2, and a driving belt 401 is connected between the output end of the air inlet drive motor 4 and the rotating shaft 301, which is used to drive the rotating shaft 301 to operate, and the arc-shaped blade 302 generates negative pressure as the rotating shaft 301 rotates, thereby realizing the air extraction operation;

[0063] Furthermore, sealing ring frames 6 are fixedly installed on both upper and lower sides of the body 1, and the ends of the filter 5 are rotatably connected to the corresponding sealing ring frames 6. Through the setting of the sealing ring frames 6, the filter 5 can maintain a sliding connection with the sealing ring frames 6 when it is running, thereby reducing the phenomenon that the air passes directly between the filter 5 and the body 1 without being filtered, and further improving the dust removal effect;

[0064] Furthermore, both sides of the interior of the body 1 are rotatably connected with side limit shafts 7, the side limit shafts 7 and the filter screen 5 are in contact with each other, and a plurality of elastic cleaning needles 701 are fixedly installed on the outside of the side limit shafts 7 for cleaning the filter screen 5.
