Description
Technical Field
[0001] This utility model belongs to the field of dust removal hood technology, and in particular relates to an adjustable dust removal hood for workshop dust removal. Background Technology
[0002] In industrial production, dust hoods are an indispensable dust collection device. Their function is to collect the dust generated during the production process in the workshop through negative pressure adsorption, prevent the dust from spreading and polluting the workshop environment, and protect the health of workers and the normal operation of equipment.
[0003] Currently, most dust hoods commonly used in workshops are simple, fixed hoods. These hoods are usually directly fixed above or beside dust-generating equipment, relying solely on the suction system to draw in nearby dust. Their suction range depends entirely on the size and shape of the hood itself. Due to the lack of a flexible adjustment mechanism, when the location of the dust-generating point changes, or when dust removal is required at different workstations, the fixed hood cannot effectively cover the area, resulting in low dust removal efficiency.
[0004] In addition, during long-term use, a large amount of dust will adhere to the inner wall of the traditional dust hood. Once it stops working, the air extraction system loses its negative pressure effect, and the dust adhering to the inner wall of the hood will fall off and fall back into the workshop, causing pollution.
[0005] Therefore, it is essential to invent an adjustable dust hood for workshop dust removal. Utility Model Content
[0006] To address the above problems, this utility model proposes an adjustable dust collection hood for workshop dust removal. The technical solution used is as follows:
[0007] An adjustable dust collection hood for workshop dust removal includes an extraction pipe, a flexible hose, mounting rings, an adjusting frame, a fixing frame, and a dust collection hood. One end of the extraction pipe is connected to an external dust removal device via a connector, and a flexible hose is fixed to the middle of the extraction pipe via a connector. Several mounting rings are fixed to the outer side of the extraction pipe, and the mounting rings are slidably connected to corresponding structures of the adjusting frame. The adjusting frame is fixed to the lower side of the fixing frame by bolts, and the fixing frame is fixed to a fixed structure in the workshop by bolts. The end of the extraction pipe away from the external dust removal device is fixed to the dust collection hood via a connector.
[0008] Furthermore, the adjustment frame includes a first arc-shaped slide rail, a first servo motor, a second arc-shaped slide rail, and a second servo motor. Corresponding mounting rings are slidably installed inside both the first and second arc-shaped slide rails. The first arc-shaped slide rail is positioned above the second arc-shaped slide rail, and the first and second arc-shaped slide rails are perpendicular to each other. Both ends of the first and second arc-shaped slide rails are rotatably connected to the fixed frame via support bearings. One end of the first arc-shaped slide rail is fixed to the output end of the first servo motor, and the base of the first servo motor is fixed to the fixed frame with bolts. One end of the second arc-shaped slide rail is fixed to the output end of the second servo motor, and the base of the second servo motor is fixed to the fixed frame with bolts. Both the first and second servo motors are electrically connected to external dust removal equipment via data cables. This configuration allows the suction pipe to move accordingly, thereby expanding the dust collection range of the dust collection hood.
[0009] Furthermore, the dust collection hood includes a hood body, a cross, an impeller, and a cleaning strip. The hood body is fixed to the exhaust pipe via a connector, and a cross is bolted to the inside of the hood body. An impeller is rotatably mounted on the cross via a support bearing. A cleaning strip is bolted to the central shaft of the impeller. Several bristles are fixed to the side of the cleaning strip near the inner wall of the hood, and these bristles are in contact with the inner wall of the hood. This design can prevent dust from adhering to the inner wall of the hood during use.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. The adjustment frame of this utility model can, firstly, drive the first arc-shaped slide rail to rotate via the first servo motor, so that the suction pipe slides along the second arc-shaped slide rail; secondly, drive the second arc-shaped slide rail to rotate via the second servo motor, so that the suction pipe slides along the first arc-shaped slide rail. Through the combination of these two actions, the dust collection hood can move within a certain space, thus expanding the dust collection range.
[0012] 2. The refresh mechanism of this utility model allows external gas to enter the hood, which in turn drives the impeller to rotate. The impeller then moves the cleaning strips, and the bristles on the cleaning strips clean the inner wall of the hood. The cleaned dust enters the exhaust pipe under the action of airflow and is transported to the external dust removal equipment, thereby keeping the inner wall of the dust collection hood clean and preventing dust from adhering to the inner wall of the hood and falling into the workshop when not in use.

[0021] Please see Figure 1As shown, this utility model is an adjustable dust collection hood for workshop dust removal, including an exhaust pipe 1, a flexible hose 2, mounting rings 3, an adjusting frame 4, a fixing frame 5, and a dust collection hood 6. One end of the exhaust pipe 1 is connected to an external dust removal device through a connector, and the flexible hose 2 is fixed to the middle of the exhaust pipe 1 through a connector. Several mounting rings 3 are fixed to the outer side of the exhaust pipe 1, and the mounting rings 3 are slidably connected to the corresponding structures of the adjusting frame 4. The adjusting frame 4 is fixed to the lower side of the fixing frame 5 by bolts, and the fixing frame 5 is fixed to the fixed structure of the workshop by bolts. The end of the exhaust pipe 1 away from the external dust removal device is fixed to the dust collection hood 6 through a connector.
[0022] like Figure 2 As shown, the adjustment frame 4 includes a first arc-shaped slide rail 41, a first servo motor 42, a second arc-shaped slide rail 43, and a second servo motor 44. Each of the first and second arc-shaped slide rails 41 and 43 has a corresponding mounting ring 3 slidably installed inside. The first arc-shaped slide rail 41 is positioned above the second arc-shaped slide rail 43, and the first and second arc-shaped slide rails 41 are perpendicular to each other. Both ends of the first and second arc-shaped slide rails 41 and 43 are rotatably connected to the fixed frame 5 via support bearings. One end of the first arc-shaped slide rail 41 is fixed to the output end of the first servo motor 42, and the base of the first servo motor 42 is fixed to the fixed frame 5 by bolts. One end of the second arc-shaped slide rail 43 is connected to the second servo motor 44. The output end of the second servo motor 44 is fixed, and the base of the second servo motor 44 is fixed to the fixing frame 5 by bolts. The first servo motor 42 and the second servo motor 44 are both electrically connected to the external dust removal equipment through data cables. When in use, the first servo motor 42 can drive the first arc-shaped slide rail 41 to rotate accordingly, thereby causing the first arc-shaped slide rail 41 to make the suction pipe 1 slide along the second arc-shaped slide rail 43 accordingly. Secondly, the second servo motor 44 can drive the second arc-shaped slide rail 43 to rotate accordingly, thereby causing the second arc-shaped slide rail 43 to make the suction pipe 1 slide along the first arc-shaped slide rail 41 accordingly. Through the above actions, the dust collection hood 6 can move accordingly, thereby expanding the dust collection range of the dust collection hood 6.
[0023] like Figure 3As shown, the dust collection hood 6 includes a hood body 61, a cross 62, an impeller 63, and a cleaning strip 64. The hood body 61 is fixed to the exhaust pipe 1 via a connector, and the cross 62 is fixed inside the hood body 61 by bolts. The impeller 63 is rotatably mounted on the cross 62 via a support bearing. The cleaning strip 64 is fixed to the central shaft of the impeller 63 by bolts. Several bristles are fixed on the side of the cleaning strip 64 near the inner wall of the hood body 61. The bristles are in contact with the inner wall of the hood body 61. When external gas passes through the inside of the hood body 61, it can drive the impeller 63 to rotate. The rotation of the impeller 63 can drive the cleaning strip 64 to move accordingly, thereby making the bristles on the cleaning strip 64 clean the inner wall of the hood body 61. The dust that is cleaned off will enter the exhaust pipe 1 under the action of the airflow.
[0024] Please see Figure 1-3 As shown, this utility model is an adjustable dust collection hood for workshop dust removal. Its working principle is as follows: During use, through the cooperation of the exhaust pipe 1, hose 2, dust collection hood 6 and external dust removal equipment, the interior of the workshop can be evacuated. During the evacuation process, the position of the dust collection hood 6 can be adjusted by the adjusting frame 4, thereby adjusting the evacuation position. In addition, when the external gas enters the hood 61, it drives the impeller 63 to rotate, which in turn drives the bristles on the cleaning strip 64 to clean the inner wall of the hood 61 (the cleaned dust enters the exhaust pipe 1 under the action of airflow and is transported to the external dust removal equipment).
