[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] like Figures 1 to 10 As shown, a dust collection hood that is easy to maintain includes: a frame 5, with a cover 2 on the outside of the frame 5; a rotating tube 3, which has a T-shaped structure, with one end of the horizontal tube 301 of the rotating tube 3 closed and fixed with a rotating shaft 303, the rotating shaft 303 being rotatably connected to the base 6 via a bearing, and the vertical tube 302 of the rotating tube 3 communicating with the inside of the cover 2; a connecting assembly, with one end of the rotating tube 3 away from the rotating shaft 303 being rotatably connected to a fixed tube 4 via the connecting assembly; and a driving assembly, which is used to drive the frame 5 to rotate along the horizontal tube 301 of the rotating tube 3.

[0042] A reinforcing rib 304 is fixed on the side wall of the rotating shaft 303. The reinforcing rib 304 improves the structural strength of the rotating shaft 303. The rotating shaft 303 is rotatably connected to the bearing seat through the bearing, and the bearing seat is fixedly connected to the base 6.

[0043] The connecting assembly includes two arc-shaped plates 8 with an arc of 180°. The two ends of the arc-shaped plates 8 are provided with ear plates 801, and the ear plates 801 are provided with connecting holes 802. The first connecting bolt 10 passes through the connecting holes 802 of the two arc-shaped plates 8 and is threadedly connected to the base 6.

[0044] An installation groove 803 is opened on the inner side of the arc plate 8. A first connecting ring 305 is fixed on the outer side of one end of the horizontal tube 301 near the connecting component. A second connecting ring 401 is fixed on the outer side of one end of the fixed tube 4 near the connecting component. The first connecting ring 305 and the second connecting ring 401 are both installed on the inner side of the installation groove 803.

[0045] The mounting groove 803 limits the first connecting ring 305 and the second connecting ring 401, allowing the first connecting ring 305 to rotate along the mounting groove 803. The rotating tube 3 can be quickly disassembled through the first connecting bolt 10, improving the efficiency of maintenance.

[0046] The thickness of the first connecting ring 305 matches the thickness of the second connecting ring 401. The width of the mounting groove 803 is twice the thickness of the first connecting ring 305. A wear-resistant layer is provided on the end face of the first connecting ring 305 adjacent to the second connecting ring 401. The wear-resistant layer improves the service life of the first connecting ring 305.

[0047] The bottom of the mounting groove 803 is provided with a sealing gasket 11 corresponding to the outer wall of the first connecting ring 305 and the second connecting ring 401. The sealing gasket 11 is a 180° arc-shaped structure made of high-density sponge material. The sealing gasket 11 improves the sealing effect, and the inner diameter of the sealing gasket 11 is smaller than the outer diameter of the first connecting ring 305 and the second connecting ring 401. During installation, the outer sides of the first connecting ring 305 and the second connecting ring 401 squeeze the sealing gasket 11 to further ensure the sealing effect.

[0048] A rotation guide assembly 9 is provided at the end of the horizontal tube 301 away from the rotation shaft 303. The guide assembly 9 includes a U-shaped plate 902 and a top plate 901. Two rollers 903 are provided on the upper surface of the horizontal plate of the U-shaped plate 902. The axial distance between the two rollers 903 on the horizontal plate is smaller than the outer diameter of the horizontal tube 301. Two rollers 903 are provided on the lower surface of the top plate 901. The axial distance between the two rollers 903 on the top plate 901 is smaller than the outer diameter of the horizontal tube 301. The horizontal tube 301 is located between the two rollers 903 on the top plate 901 and the two rollers 903 on the horizontal plate. The sidewalls of the rollers 903 are in contact with the outer sidewall of the horizontal tube 301, which provides support and rotation guidance for the horizontal tube 301. In conjunction with the rotation of the other end, the stability of the rotation process of the rotating tube 3 is ensured.

[0049] The top plate 901 has a mounting hole, and the upper end of the vertical plate of the U-shaped plate 902 has a threaded hole. The second connecting bolt 12 passes through the mounting hole and is threaded to the inside of the threaded hole. The setting of the second connecting bolt 12 facilitates the disassembly of the rotating tube 3 and facilitates maintenance.

[0050] In some embodiments, the driving component is a hydraulic cylinder 7. The housing of the hydraulic cylinder 7 is hinged to the base 6, and the output shaft of the hydraulic cylinder 7 is hinged to the frame 5. The extension and retraction of the output shaft of the hydraulic cylinder 7 causes the frame 5 and the cover 2 to rotate. The housing of the hydraulic cylinder 7 is located at the lower end of the cover 2. When the output shaft of the hydraulic cylinder 7 extends, it causes the frame 5 and the cover 2 to move upward.

[0051] In other embodiments, the drive component is a motor, with a drive gear fixed on the output shaft of the motor and a driven gear on the horizontal tube 301. The driven gear meshes with the drive gear, and the motor housing is fixedly connected to the base 6.

[0052] The cover 2 and the frame 5 are detachably connected by bolts, making it easy to replace the cover 2.

[0053] Compared to traditional fixed dust collection hoods, the position of the hood can be quickly adjusted by using the rotating tube 3 and the drive assembly, which facilitates the maintenance and repair of the dust collection equipment 1 and improves work efficiency.
