[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:

[0032] Example 1:

[0033] In this embodiment of the invention, a micro-powered dust control machine capable of automatic dust collection includes a body 1, with an air inlet hood 2 installed on the side of the body 1. The air inlet hood 2 is used to extract air containing dust. During operation, the body 1 is first installed in a location with a large amount of dust. The air and dust are extracted through the operation of the air inlet hood 2 and then transported to the interior of the body 1 for filtration.

[0034] In this embodiment of the invention, specifically, both sides of the inner side of the machine body 1 are rotatably connected to a drive shaft 501, and a filter screen 5 is rotatably connected between the two drive shafts 501. The filter screen 5 is used to filter dust in the air. A filter plate 101 is fixedly installed inside the machine body 1. The filter plate 101 is used to perform secondary filtration of the air. When air enters the machine body 1, the filter screen 5 can filter the dust in the air until the filtered air is discharged after secondary filtration by the filter plate 101.

[0035] Furthermore, a cleaning shaft 8 is rotatably connected inside the body 1, and multiple elastic paddles 801 are fixedly installed on the outside of the cleaning shaft 8. The cleaning shaft 8 is installed inside the filter screen 5, and is used to beat the running filter screen 5 through the multiple elastic paddles 801 to make the dust adhering to its surface fall off. When the filter screen 5 filters the dust in the air, the rotation of the drive shaft 501 can drive the filter screen 5 to run inside the body 1 to ensure the filtration effect. At the same time, when the filter screen 5 is running, the rotation of the cleaning shaft 8 can drive the elastic paddles 801 to rotate and beat the filter screen 5, making the dust adhering to the surface of the filter screen 5 fall off.

[0036] Specifically, a bottom sealing plate 10 is provided at the bottom of the machine body 1. A waste discharge trough 1001 is provided on one side inside the bottom sealing plate 10. A feeding hopper 11 is fixedly installed below the waste discharge trough 1001. A sealing rotating plate 13 is rotatably connected inside the feeding hopper 11. The dust deposited by the rotation of the sealing rotating plate 13 is discharged. As the elastic baffle 801 knocks off the dust adhering to the surface of the filter screen 5, the dust can fall into the feeding hopper 11 through the waste discharge trough 1001.

[0037] Specifically, during the dust collection process, the sealing rotating plate 13 is in a horizontal position, sealing the discharge hopper 11. (Refer to...) Figure 5 , Figure 6 On the one hand, it ensures the airtightness of the machine body 1, so as to better collect dust, and on the other hand, it can prevent air from being discharged through the hopper 11, causing the collected dust to drift away with the air.

[0038] Specifically, the sealed rotating plate 13 is equipped with a weight sensing module to sense the weight of the dust accumulated above. When the weight reaches a certain value, the sealed rotating plate 13 rotates, so that the collected dust can be automatically discharged through the hopper 11, further ensuring the dust control effect.

[0039] Specifically, the weight sensing module is an existing device, and its control is based on the existing PLC control module, which will not be elaborated here;

[0040] Specifically, the bottom sealing plate 10 has an inclined surface inside, and the waste discharge trough 1001 is located at the lower end of the inclined surface to allow the deposited dust to be discharged through the waste discharge trough 1001. When the equipment is running, it can generate vibration, so that the dust falling on the bottom sealing plate 10 can enter the waste discharge trough 1001 along the inclined surface, further realizing the dust collection operation.

[0041] Specifically, a motor is fixedly installed on the top surface of the machine body 1 to drive the transmission shaft 501. A transmission belt 9 is rotatably connected between the end of the cleaning shaft 8 and the end of the transmission shaft 501 to drive the cleaning shaft 8 to run inside the filter screen 5. The motor is an existing device and will not be described in detail here.

[0042] Specifically, a steering motor 14 is fixedly installed on the outside of the hopper 11. The output end of the steering motor 14 passes through the hopper 11 and is connected to the sealing rotating plate 13 to drive the sealing rotating plate 13 to rotate inside the hopper 11. The steering motor 14 is an existing device, and its output end is connected to the middle of the sealing rotating plate 13 to realize the driving operation.

[0043] Specifically, the waste discharge end of the aforementioned body 1 refers to the end where the waste discharge slot 1001 is located on the bottom sealing plate 10.

[0044] Specifically, a positioning frame 3 is fixedly installed inside the air inlet hood 2, and a rotating shaft 301 is rotatably installed inside the positioning frame 3. An arc-shaped blade 302 is fixedly sleeved on the outside of the rotating shaft 301. An air inlet drive motor 4 is fixedly installed on the top surface of the air inlet hood 2. A drive belt 401 is connected between the output end of the air inlet drive motor 4 and the rotating shaft 301 to drive the rotating shaft 301 to run. The arc-shaped blade 302 generates negative pressure as the rotating shaft 301 rotates, thereby realizing the air extraction operation.

[0045] Example 2: Based on Example 1, a micro-powered dust control machine capable of automatic dust collection includes a body 1. An air inlet hood 2 is installed on the side of the body 1. The air inlet hood 2 is used to extract air containing dust. During operation, the body 1 is first installed in a location with a lot of dust. The air and dust are extracted by the operation of the air inlet hood 2 and then transported into the body 1 for filtration.

[0046] In this embodiment of the invention, specifically, both sides of the inner side of the machine body 1 are rotatably connected to a drive shaft 501, and a filter screen 5 is rotatably connected between the two drive shafts 501. The filter screen 5 is used to filter dust in the air. A filter plate 101 is fixedly installed inside the machine body 1. The filter plate 101 is used to perform secondary filtration of the air. When air enters the machine body 1, the filter screen 5 can filter the dust in the air until the filtered air is discharged after secondary filtration by the filter plate 101.

[0047] Furthermore, a cleaning shaft 8 is rotatably connected inside the body 1, and multiple elastic paddles 801 are fixedly installed on the outside of the cleaning shaft 8. The cleaning shaft 8 is installed inside the filter screen 5, and is used to beat the running filter screen 5 through the multiple elastic paddles 801 to make the dust adhering to its surface fall off. When the filter screen 5 filters the dust in the air, the rotation of the drive shaft 501 can drive the filter screen 5 to run inside the body 1 to ensure the filtration effect. At the same time, when the filter screen 5 is running, the rotation of the cleaning shaft 8 can drive the elastic paddles 801 to rotate and beat the filter screen 5, making the dust adhering to the surface of the filter screen 5 fall off.

[0048] Specifically, a bottom sealing plate 10 is provided at the bottom of the machine body 1. A waste discharge trough 1001 is provided on one side inside the bottom sealing plate 10. A feeding hopper 11 is fixedly installed below the waste discharge trough 1001. A sealing rotating plate 13 is rotatably connected inside the feeding hopper 11. The dust deposited by the rotation of the sealing rotating plate 13 is discharged. As the elastic baffle 801 knocks off the dust adhering to the surface of the filter screen 5, the dust can fall into the feeding hopper 11 through the waste discharge trough 1001.

[0049] Specifically, during the dust collection process, the sealing rotating plate 13 is in a horizontal position, sealing the discharge hopper 11. (Refer to...) Figure 5 , Figure 6 On the one hand, it ensures the airtightness of the machine body 1, so as to better collect dust, and on the other hand, it can prevent air from being discharged through the hopper 11, causing the collected dust to drift away with the air.

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

[0051] Specifically, the weight sensing module is an existing device, and its control is based on the existing PLC control module, which will not be elaborated here;

[0052] Furthermore, a limiting groove 1002 is provided inside the bottom sealing plate 10, and a sealing plate 12 is slidably connected inside the limiting groove 1002. A transmission plate 1202 is fixedly installed on one side of the top surface of the sealing plate 12. The installation position of the transmission plate 1202 is located between the filter screen 5 and the inner wall of the body 1. It is used to drive the sealing plate 12 to slide through the air pressure when the sealing rotating plate 13 rotates, so as to automatically complete the sealing of the waste discharge trough 1001.

[0053] Specifically, when the sealing rotating plate 13 is in a horizontal position and blocks the hopper 11, the blocking slide plate 12 can be retracted into the limiting slide groove 1002 during the air filtration process. At this time, the dust can fall through the waste discharge trough 1001. When the sealing rotating plate 13 rotates to perform dust discharge, the transmission plate 1202 is affected by the wind pressure and can drive the blocking slide plate 12 to slide towards the waste discharge trough 1001 until the waste discharge trough 1001 is blocked. This ensures the dust discharge effect when the sealing rotating plate 13 rotates and prevents the wind from rolling the collected dust back into the machine body 1, further improving the dust control effect of the equipment.

[0054] Specifically, when the dust removal is completed, the sealing rotating plate 13 rotates to the state of sealing the discharge hopper 11. At this time, the air cannot pass through the waste discharge end of the machine body 1, which reduces the wind pressure on the transmission plate 1202. The sealing slide plate 12 can be reset by the elastic pull rope 1201 and retract into the limit slide groove 1002, so that the waste discharge trough 1001 can be reopened, thus completing one automatic waste discharge process.

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

[0056] Specifically, the bottom sealing plate 10 has an inclined surface inside, and the waste discharge trough 1001 is located at the lower end of the inclined surface to allow the deposited dust to be discharged through the waste discharge trough 1001. When the equipment is running, it can generate vibration, so that the dust falling on the bottom sealing plate 10 can enter the waste discharge trough 1001 along the inclined surface, further realizing the dust collection operation.

[0057] Specifically, a motor is fixedly installed on the top surface of the machine body 1 to drive the transmission shaft 501. A transmission belt 9 is rotatably connected between the end of the cleaning shaft 8 and the end of the transmission shaft 501 to drive the cleaning shaft 8 to run inside the filter screen 5. The motor is an existing device and will not be described in detail here.

[0058] Specifically, a steering motor 14 is fixedly installed on the outside of the hopper 11. The output end of the steering motor 14 passes through the hopper 11 and is connected to the sealing rotating plate 13 to drive the sealing rotating plate 13 to rotate inside the hopper 11. The steering motor 14 is an existing device, and its output end is connected to the middle of the sealing rotating plate 13 to realize the driving operation.

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

[0060] Specifically, the side of the transmission plate 1202 closest to the inner wall of the machine body 1 is attached to it to scrape off the dust adhering to the inner wall of the machine body 1 during operation. A distance is left between the side of the transmission plate 1202 closest to the filter screen 5 and the filter screen 5 to prevent the filter screen 5 from contacting the transmission plate 1202 during operation and to keep the dust from entering the waste discharge end of the machine body 1.

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

[0062] Specifically, a positioning frame 3 is fixedly installed inside the air inlet hood 2, and a rotating shaft 301 is rotatably installed inside the positioning frame 3. An arc-shaped blade 302 is fixedly sleeved on the outside of the rotating shaft 301. An air inlet drive motor 4 is fixedly installed on the top surface of the air inlet hood 2. A drive belt 401 is connected between the output end of the air inlet drive motor 4 and the rotating shaft 301 to drive the rotating shaft 301 to run. 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 the upper and lower sides inside the body 1. The ends of the filter screen 5 are rotatably connected to the corresponding sealing ring frames 6. Through the setting of the sealing ring frames 6, the filter screen 5 can maintain a sliding connection with the sealing ring frames 6 when it is running, reducing the phenomenon that unfiltered air passes directly between the filter screen 5 and the body 1, and further improving the dust removal effect.

[0064] Furthermore, both sides of the inner side of the body 1 are rotatably connected to side limiting shafts 7. The side limiting shafts 7 are in contact with the filter screen 5, and multiple elastic cleaning needles 701 are fixedly installed on the outer side of the side limiting shafts 7 for cleaning the filter screen 5. By setting the side limiting shafts 7, air can be blocked, and the side limiting shafts 7 can move with the filter screen 5 and clean the filter screen 5 through the externally installed elastic cleaning needles 701, so as to avoid the mesh from being blocked and affecting the filtration effect, thereby further improving the dust control effect and maintenance convenience of the equipment.

[0065] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0066] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
