Description

Technical Field

[0001] The utility model relates to the technical field of dust removal fans, in particular to a dust removal fan with an angle adjustment function. Background Art

[0002] With the continuous development of society, all walks of life are also developing by leaps and bounds. Some industries will generate a lot of dust in the production process. If these dusts are directly discharged into the air, they will cause great pollution to the environment. Generally, dust removal fans are used to improve indoor air.

[0003] At present, a large amount of dust is generated in industrial production, so a dust removal fan is needed to remove the generated dust. When the existing dust removal fan is used, its air inlet pipe is fixedly installed with the dust removal fan, and the angle cannot be adjusted. It can only adsorb dust in a fixed direction, which results in a limited range of dust absorption during use, affecting the dust removal efficiency.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the above background technology, the prior art has the disadvantages and defects that the dust collection angle cannot be adjusted at multiple angles.

[0006] The utility model discloses a dust removal fan with an angle adjustment function, comprising a dust removal machine, the outer surface of which is fixedly connected to a dust suction hose, the right end of which is fixedly connected to a sliding block, a support frame is provided on the right side of the dust removal machine, the interior of the support frame is rotatably connected to two hand wheels, the interior of the support frame is threadedly connected to a bolt, the outer surface of the bolt contacts the outer surface of the corresponding hand wheel, a longitudinal ring frame and a transverse ring frame are provided on the right side of the support frame, the outer surface of each hand wheel is fixedly connected to the outer surface of the corresponding longitudinal ring frame and transverse ring frame, and the left side of the longitudinal ring frame is provided with two sliding grooves.

[0007] By adopting the above scheme, the slider limits the position of the dust suction hose and enables the dust suction hose to move synchronously with the slider. The relative hand wheel one is limited by bolt one to prevent hand wheel one from sagging due to the influence of the horizontal ring frame, thereby achieving the function of adjusting the dust suction angle. The cooperation between the longitudinal ring frame and the horizontal ring frame and the slider enables the slider to achieve multi-angle changes, thereby improving the dust suction ability.

[0008] Optionally, the inner wall of each of the slide grooves 1 is slidably connected to the outer surface of the slider, and the outer surface of the transverse ring frame is provided with two slide grooves 2.

[0009] By adopting the above solution, the slide groove 1 provides a passage for the slider to move up and down, so that the slider can drive the vacuum hose to move up and down, thereby increasing the vacuum range of the vacuum hose.

[0010] Furthermore, the inner wall of each of the slide grooves 2 is slidably connected to two bolts 2, and the outer surface of each of the bolts 2 is threadedly connected to the left side surface of the slider.

[0011] By adopting the above solution, the second slide groove provides a left and right movement path for the second bolt, and the second bolt limits the position of the second bolt to prevent the longitudinal ring frame from being unable to drive the slider to move left and right.

[0012] Furthermore, a fixing frame is provided on the right side of the dust collector, and two threaded rods are rotatably connected inside the fixing frame.

[0013] By adopting the above solution, the fixing frame is located on the left side of the supporting frame, providing supporting force for the supporting frame, so that the supporting frame and the sliding block remain suspended, preventing the longitudinal ring frame and the transverse ring frame from being affected in rotation.

[0014] Furthermore, the outer surface of each threaded rod is threadedly connected to a fixing block, and the outer surface of each fixing block is fixedly connected to the right side surface of the support frame.

[0015] By adopting the above solution, the fixed block is the fulcrum of the support frame, and the threaded rod provides the support frame with an up and down movement function.

[0016] Furthermore, a gear is fixedly connected to the top of each threaded rod, and a toothed belt is provided above the fixing frame.

[0017] By adopting the above solution, the gear provides the threaded rod with the power required for rotation, and at the same time the rotation directions of the gear and the threaded rod are kept consistent.

[0018] Furthermore, the outer surface of each of the gears is meshed with the inner wall of the toothed belt, and a hand wheel 2 is fixedly connected to the upper surface of one of the gears.

[0019] By adopting the above scheme, the toothed belt is meshed with the gear, so that the two gears rotate at the same time and maintain the same direction and speed, so that the support frame rises to provide stability.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] 1. The utility model provides components such as a slider, a longitudinal ring frame, and a transverse ring frame, and rotates a hand wheel to drive the corresponding longitudinal ring frame and the transverse ring frame to rotate. When the left and right angles of the dust suction hose need to be adjusted, the longitudinal ring frame is driven to move by rotating the corresponding hand wheel, and the longitudinal ring frame drives the slider to move, and the slider drives the bolt 2 to slide on the inner wall of the slide groove 2, so as to adjust the angle of the dust suction hose left and right. When the up and down angles of the dust suction hose need to be adjusted, the transverse ring frame is driven to move by rotating the corresponding hand wheel, and the transverse ring frame drives the slider to move, and the slider slides along the inner wall of the slide groove 1, so as to adjust the angle of the dust suction hose up and down, thereby achieving the effect that the device can accurately adjust the angle of the dust suction hose.

[0022] 2. The utility model is provided with threaded rods, fixed blocks, gears, toothed belts and other components. The corresponding gears are driven to rotate by rotating the second hand wheel. At the same time, the gears are meshed with the toothed belts and drive another gear to rotate. The corresponding threaded rods are driven to rotate by the gears, and the corresponding fixed blocks are driven to rise or fall. At the same time, the fixed blocks drive the support frame to move synchronously, so that the device can adjust the height of the support frame according to different heights.
