Description

Technical Field

[0001] This utility model relates to the field of fume treatment technology, specifically to an adjustable welding fume removal device. Background Technology

[0002] Welding fumes are highly complex substances, containing more than 20 elements. The most abundant are iron, calcium, and sodium, followed by silicon, aluminum, manganese, titanium, and copper. The main harmful substances in welding fumes are iron oxide, silicon dioxide, and manganese oxide, with iron oxide being the most abundant, generally accounting for 35.5% of the total fumes. Silicon dioxide accounts for 10%–20%, and manganese oxide accounts for approximately 5%–20%. During metal welding, a large amount of fumes are suspended in the working environment. Inhaling these fumes can seriously affect health, and in severe cases, can lead to chronic manganese poisoning and welder's pneumoconiosis. Therefore, welding fumes pose a significant threat to operators, making welding fume removal devices essential to eliminate this hazard.

[0003] Existing welding fume dust removal devices require manual movement to the appropriate position when vacuuming dust from different welding locations, which is not convenient. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an adjustable welding fume dust removal device, which can solve the technical problem that existing welding fume dust removal devices require manual movement to a suitable position when vacuuming dust at different welding positions, which is not convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable welding fume dust removal device includes a dust collection box body, a mounting plate on the top of the dust collection box body, a telescopic tube on the inner side of the mounting plate, the lower end of the telescopic tube being connected to the dust collection box body, and a fixed tube being connected to the upper end of the telescopic tube. A suction tube is rotatably connected to the top end of the fixed tube. The position of the suction tube is adjusted by an adjustment mechanism, and a suction hood is provided at the front end of the suction tube.

[0007] Preferably, the adjustment mechanism includes a support plate, a mounting block is provided on one side of the top of the support plate, the end of the suction pipe away from the suction hood passes through the mounting block and the support plate and is rotatably connected to the fixed pipe, and a rocker arm is provided on the other side of the top of the support plate. One end of the rocker arm is connected to the suction pipe through a connecting rod, and the other end is connected to the output shaft of the first motor. The first motor is fixedly connected to the bottom of the support plate.

[0008] Preferably, a second motor is fixedly installed on the top of the mounting plate, and a threaded rod is connected to the output shaft of the second motor. The threaded rod passes through the support plate and its lower end is rotatably connected to the top of the dust collector body.

[0009] Preferably, slide rails are provided on both inner walls of the mounting plate, and sliders are provided on both sides of the support plate, with the sliders cooperating with the slide rails.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the dust removal device of this utility model can remove dust from different welding positions of the workpiece without moving during use. By adjusting the mechanism to drive the suction pipe to move horizontally, the suction hood is aligned with the welding position for precise dust removal, thus improving the dust removal efficiency. At the same time, by setting a motor, a threaded rod, a slider and a slide rail, the height of the suction pipe can also be adjusted. This device realizes adjustment in both horizontal and vertical directions, making it highly practical. Attached Figure Description

[0016] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0017] like Figures 1 to 2As shown, this utility model discloses an adjustable welding fume extraction device, including a dust extraction box body 1. The top of the dust extraction box body 1 is provided with a mounting plate 2, and the inner side of the mounting plate 2 is provided with a telescopic tube 3. The lower end of the telescopic tube 3 is connected to the dust extraction box body 1, and the upper end is connected to a fixed tube 4. A suction tube 5 is rotatably connected to the top end of the fixed tube 4. The suction tube 5 is adjusted in position by an adjustment mechanism, and a suction hood 6 is provided at the front end of the suction tube 5. By setting an adjustment mechanism to drive the suction tube 5 to move, the horizontal position of the suction hood 6 can be adjusted, facilitating the adsorption of welding fumes from different locations on the welded parts. This adjustment mechanism can also cause the suction tube 5 to swing left and right, which helps to increase the adsorption area.

[0018] Furthermore, in this embodiment, the adjustment mechanism includes a support plate 7, with a mounting block 8 on one side of the top of the support plate 7. One end of the suction pipe 5, away from the dust cover 6, passes through the mounting block 8 and the support plate 7 and is rotatably connected to the fixed pipe 4. A rocker arm 9 is provided on the other side of the top of the support plate 7. One end of the rocker arm 9 is connected to the suction pipe 5 via a connecting rod 10, and the other end is connected to the output shaft of a motor 11. The motor 11 is fixedly connected to the bottom of the support plate 7. During adjustment, the motor 11 is started, causing the rocker arm 9 to rotate. The rocker arm 9 then moves the suction pipe 5 via the connecting rod 10, thereby adjusting the position of the dust cover 6.

[0019] A second motor 12 is fixedly mounted on the top of the mounting plate 2. A threaded rod 13 is connected to the output shaft of the second motor 12. The threaded rod 13 passes through the support plate 7 and its lower end is rotatably connected to the top of the dust collection box body 1. Slide tracks 14 are provided on both inner walls of the mounting plate 2, and sliders 15 are provided on both sides of the support plate 7. The sliders 15 cooperate with the slide tracks 14. By setting the second motor 12, the threaded rod 13, the slide tracks 14, and the sliders 15, the height of the dust collection hood 6 can be adjusted. During adjustment, the second motor 12 is started, which drives the threaded rod 13 to rotate. Under the limit of the sliders 15 and the slide tracks 14, the support plate 7 moves up and down along the threaded rod 13, thereby achieving adjustment.

[0020] Working Principle: In use, fix this device to one side of the welding station and adjust the position of the dust hood 6 according to the welding position of the workpiece. First, adjust the height of the dust hood 6 by starting motor 12. Motor 12 drives the threaded rod 13 to rotate. Under the limit of slider 15 and slide rail 14, support plate 7 moves upward along threaded rod 13 until the appropriate height is achieved. Next, adjust the horizontal position of the dust hood 6. According to different welding positions of the workpiece, adjust the dust hood 6 to precisely align it with the welding fumes. Start motor 11. Motor 11 drives rocker arm 9 to rotate. Rocker arm 9 drives the suction pipe 5 to move through connecting rod 10, thereby adjusting the position of the dust hood 6. This device can be set to continuously operate motor 11 according to usage, which facilitates driving the suction pipe 5 and thus the dust hood 6 to swing left and right, increasing the suction area.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
