[0002] The pulse bag dust collector is a bag dust collector that cleans dust by pulse cleaning. The cleaning system of the pulse bag dust collector is composed of several parts such as pulse valve, blow pipe, air storage bag and pulse controller. The chamber dust collector is additionally equipped with a cylinder. One end of the pulse valve is connected to the compressed air bag and the other end is connected to the blow pipe. The back pressure chamber of the pulse valve is connected to the control valve. The pulse controller controls the opening of the main control valve and the pulse valve.

[0003] A Chinese patent discloses a pulse bag dust collector device (authorization announcement number CN217988671U). This patented technology can process dust in different chambers by setting an adjustment device and a main device on the entire device, adjust the pulse airflow, reduce power loss, and significantly improve the overall dust removal efficiency and effect, thereby improving work efficiency.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: in actual use, the dust adsorbed by the existing pulse bag dust collector will be discharged downward by itself and will accumulate at the bottom of the dust collector device, which may easily cause secondary pollution. It is inconvenient for the staff to collect and clean the dust in a centralized manner, which increases the workload of the staff. Utility Model Content

[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Reference Figure 1 - Figure 6As shown, the utility model provides a technical solution: a pulse bag dust collector with automatic dust unloading function, including a dust collector body 1, the dust collector body 1 is fixedly connected with legs 2 on all sides, a funnel 3 is installed at the bottom of the dust collector body 1, the bottom of the funnel 3 is fixedly connected with a storage frame 4, the inner wall of the storage frame 4 is slidably connected with a storage box 5, both sides of the storage frame 4 are fixedly connected with a first extension plate 6, the front end of the first extension plate 6 is fixedly connected with a cylinder 7, the surface of the cylinder 7 is rotatably connected with a limit plate 8, one end of the first extension plate 6 is fixedly connected with a second extension plate 9, the bottom of the second extension plate 9 is fixedly connected with a first spring 10, the bottom of the first spring 10 is connected to the top of the limit plate 8 The fixed connection is that the staff presses down one end of the limit plate 8 to pull the first spring 10 to accumulate force, so that the limit plate 8 is moved away from the front end of the storage box 5, so that the storage box 5 can be drawn out from the storage frame 4. When the staff inserts the storage box 5 into the storage frame 4, the limit plate 8 is loosened to release the force generated by the first spring 10, so that the first spring 10 rebounds and pulls the limit plate 8 to rotate on the surface of the cylinder 7 to the front end of the storage box 5, abuts against the storage box 5, and restricts the storage box 5 in the storage frame 4, which is convenient for the staff to take out the storage box 5 to clean the collected dust and prevent the dust from falling and polluting the environment. The storage box 5 is quickly installed and fixed, and the storage box 5 is quickly disassembled.

[0026] Reference Figure 1 , Figure 2 and Figure 6 As shown, in the present embodiment: a sliding groove 11 is provided inside the limit plate 8, and a sliding rod 12 is slidably connected to the inner wall of the sliding groove 11, and one end of the sliding rod 12 is fixedly connected to the second extension plate 9. Through the sliding connection between the sliding groove 11 and the sliding rod 12, the rotation trajectory of the limit plate 8 driven by the first spring 10 is restricted to prevent the limit plate 8 from deviating during rotation, so that the limit plate 8 can abut the front end of the storage box 5 more accurately and tightly.

[0027] Reference Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment: a nut block 13 is installed on one side of the limit plate 8, and the internal thread of the nut block 13 is connected to a screw 14. When the staff turns the screw 14, the nut block 13 moves into the inner wall of the slide groove 11 and abuts against the surface of the slide rod 12, so that the position of the limit plate 8 is limited by the screw 14 and no longer rotates. Anyway, the vibration generated by the device causes the first spring 10 to loosen, causing the limit plate 8 to detach from the front end of the storage box 5.

[0028] Reference Figure 1 , Figure 2 and Figure 6As shown, in this embodiment: the sliding rod 12 is placed on the inner wall of the first spring 10, and the surface of the sliding rod 12 is slidably connected to the inner wall of the first spring 10. Through the sliding connection between the sliding rod 12 and the first spring 10, the first spring 10 moves closely against the surface of the sliding rod 12 during operation, thereby preventing the first spring 10 from curling up during rebound and causing entanglement that affects the normal operation of the component.

[0029] Reference Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment: the shape of the limiting plate 8 is an inclined L-shaped structure. Through the inclined L-shaped structure design of the limiting plate 8, the limiting plate 8 only needs to rotate a slight angle on the surface of the cylinder 7 to make one end of the limiting plate 8 detach from the surface of the storage box 5.

[0030] Reference Figure 3 and Figure 4 As shown, in the present embodiment: first rounded corners 15 are provided on both sides of the bottom of the storage frame 4, and second rounded corners 16 are provided on both sides of the bottom of the storage box 5. Through the smooth design of the first rounded corners 15 at the bottom of the storage frame 4 and the second rounded corners 16 at the bottom of the storage box 5, the storage box 5 moves more smoothly and is not prone to jamming when inserted into the storage frame 4, which is convenient for the staff to take out or place the storage box 5 into the storage frame 4.

[0031] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment: a mounting shell 17 is installed on one side of the funnel 3, and a rotating rod 18 is rotatably connected inside the mounting shell 17, and a rotating handle 19 is fixedly connected to one end of the rotating rod 18, and a propeller 20 is fixedly connected to the surface of the rotating rod 18, and an extension column 21 is rotatably connected to one end of the rotating rod 18, and one end of the extension column 21 is fixedly connected to one side of the inner wall of the funnel 3. The staff holds the rotating handle 19 to drive the rotating rod 18 to rotate in the mounting shell 17, so that the propeller 20 on the surface of the rotating rod 18 stirs the dust accumulated on the inner wall of the funnel 3 to loosen the accumulated dust, thereby preventing the dust from clogging due to long-term accumulation and being unable to be discharged.

[0032] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment: two first circular grooves 22 are provided inside the mounting shell 17, and two second circular grooves 23 are provided on the surface of the rotating rod 18. The inner walls of the first circular groove 22 and the second circular groove 23 are both slidably connected with a plurality of balls 24. When the rotating rod 18 rotates, the plurality of balls 24 rolling in the second circular grooves 23 and the first circular grooves 22 reduce the contact area between the rotating rod 18 and the mounting shell 17, reduce the friction resistance generated by the rotation of the rotating rod 18, and make the rotation of the rotating rod 18 smoother and more labor-saving.

[0033] Working principle: The staff presses down one end of the limit plate 8 to pull the first spring 10 to store force, so that the limit plate 8 moves away from the front end of the storage box 5, so that the storage box 5 can be drawn out of the storage frame 4. When the staff inserts the storage box 5 into the storage frame 4, the limit plate 8 is released to release the force generated by the first spring 10, so that the first spring 10 rebounds and pulls the limit plate 8 to rotate on the surface of the cylinder 7 to the front end of the storage box 5, abuts against the storage box 5, and limits the storage box 5 in the storage frame 4, which is convenient for the staff to take out the storage box 5 to clean the collected dust and prevent dust from falling and polluting. The storage box 5 can be quickly installed and fixed to achieve quick disassembly of the storage box 5. The sliding connection between the slide groove 11 and the slide rod 12 limits the rotation trajectory of the limit plate 8 driven by the first spring 10 to prevent the limit plate 8 from deviating when rotating, so that the limit plate 8 can abut the front end of the storage box 5 more accurately and tightly. When the staff turns the screw 14 and moves it into the inner wall of the slide groove 11 through the nut block 13, it abuts against the surface of the slide rod 12, so that the position of the limit plate 8 is limited by the screw 14 and no longer rotates, preventing the device from vibrating and causing the first spring 10 to loosen and cause the limit plate 8 to move from the storage box 5. The front end of the storage box 5 is detached, and the sliding connection between the slide bar 12 and the first spring 10 is made so that the first spring 10 moves closely against the surface of the slide bar 12 during operation, so as to prevent the first spring 10 from curling up and causing winding when rebounding, which affects the normal operation of the assembly. The inclined L-shaped structure design of the limit plate 8 allows the limit plate 8 to rotate slightly on the surface of the cylinder 7 to detach one end of the limit plate 8 from the surface of the storage box 5. The rounded design of the first fillet 15 at the bottom of the storage frame 4 and the second fillet 16 at the bottom of the storage box 5 makes it smoother and less likely to move when the storage box 5 is inserted into the storage frame 4. The staff can easily take out or put the storage box 5 into the storage frame 4 by holding the handle 19 to drive the rotating rod 18 to rotate in the mounting shell 17, so that the propeller 20 on the surface of the rotating rod 18 stirs the dust accumulated on the inner wall of the funnel 3 to loosen the accumulated dust, thereby preventing the dust from clogging due to long-term accumulation and being unable to be discharged. When the rotating rod 18 rotates, the second circular groove 23 and the plurality of balls 24 rolling in the first circular groove 22 reduce the contact area between the rotating rod 18 and the mounting shell 17, thereby reducing the friction resistance generated by the rotation of the rotating rod 18, making the rotation of the rotating rod 18 smoother and more labor-saving.
