After being discharged through the discharge port 17 at the bottom of the dust hopper 1, the starting motor 13 drives the shaft column 14 to rotate, and then drives the multiple connecting rods 15 and the scraper 16 to rotate, so that the side wall of the scraper 16 scrapes the inner wall of the dust hopper 1, and then the impurities and chemical particles remaining on the inner wall of the dust hopper 1 are scraped off and discharged, so that these residual substances will not adhere to the inner wall of the dust hopper 1 for a long time and cause corrosion to the dust hopper 1. Through the above structure, after the mechanical dust collector completes dust discharge, the impurities remaining on the inner wall of the dust collecting device can be scraped off and discharged, reducing the situation where impurities adhere to the inner wall of the dust collecting device for a long time and cause corrosion to the dust collecting device.

[0023] like Figures 1 to 3 As shown, a fixing ring 2 is fixed to the top of the inner wall of the impurity discharge port 17; a spring 21 is fixed to the bottom of the fixing ring 2; a baffle 22 is fixed to the bottom end of the spring 21; the diameter of the baffle 22 is the same as the inner diameter of the impurity discharge port 17; a fixing cylinder 23 is fixed to the top of the baffle 22; a sliding column 24 is slidably connected to the middle of the fixing cylinder 23; the top of the sliding column 24 is fixed to the bottom of the shaft column 14; when working, when there is no accumulation of impurities inside the dust hopper 1, the fixing cylinder 23 will be in the middle of the impurity discharge port 17 near the top of the impurity discharge port 17 under the pulling force of the baffle 22. Due to the cooperation of the fixing cylinder 23 and the sliding column 24, the baffle 22 will always remain parallel to the end face of the impurity discharge port 17. After working for a period of time, some impurities will accumulate inside the dust hopper 1. At this time, these impurities will be pressed on the top of the baffle 22. As the amount of accumulated dust gradually increases, the baffle 22 will gradually move toward the bottom of the discharge port 17, so that the operator can judge the amount of impurities accumulated inside the dust hopper 1 through simple observation. After the operator determines that the dust inside the dust hopper 1 has reached a certain amount, the baffle 22 can be pulled downward to separate the baffle 22 from the bottom of the discharge port 17. At this time, the dust accumulated inside the dust hopper 1 can be discharged from the discharge port 17. Through the above structure, the operator can easily grasp the amount of dust accumulation inside the dust hopper 1, which is convenient for the operator to decide whether to perform dust discharge operation.

[0024] like Figures 1 to 4As shown, a connecting ring 3 is fixedly connected to the bottom of the baffle 22; a second fixing plate 31 is fixedly connected to the bottom of the debris discharge port 17; the bottom end of the second fixing plate 31 is rotatably connected to a pulley 32; a pull rope 33 is fixedly connected to the middle of the connecting ring 3; during operation, when it is necessary to pull down the motor 13 to discharge the dust inside the dust hopper 1, the pull rope 33 can be pulled to pass the pull rope 33 around the middle of the pulley 32, and then the pull rope 33 can be pulled horizontally to pull the baffle 22 out from the inside of the debris discharge port 17, so that the dust accumulated inside the dust hopper 1 will not fall on the hands of the operator when it is discharged from the bottom of the debris discharge port 17. Through the above structure, the dust inside the dust hopper 1 will not fall on the hands of the operator when it is discharged.

[0025] like Figures 1 to 4 As shown, the end of the pull rope 33 is fixedly connected with a round head 4; the side wall of the second fixing plate 31 is provided with a pair of first grooves 41; the side wall of the second fixing plate 31 is provided with a pair of second grooves 42; the pair of second grooves 42 are respectively connected with the pair of first grooves 41; when working, when the dust inside the dust hopper 1 is discharged by pulling the pull rope 33, the round head 4 is passed through the first groove 41 near the top of the second fixing plate 31, and then the pull rope 33 is loosened so that the pull rope 33 falls into the first groove 41, and the first groove 41 will pull the round head 4 is stuck, so that the pull rope 33 continues to pull the baffle 22, so that the baffle 22 will not rebound into the interior of the debris discharge port 17 under the pulling force of the spring 21, thereby continuously discharging the dust inside the dust hopper 1. After the discharge is completed, the round head 4 is taken out from the interior of the upper first groove 41, and then put into the interior of the lower first groove 41, so that the baffle 22 can slide into the interior of the debris discharge port 17. Through the above structure, when the dust inside the dust hopper 1 is continuously discharged, the operator does not need to continuously pull the pull rope 33, thereby improving the convenience of operation.

[0026] like Figure 1 to Figure 2 As shown, an elastic rod 5 is fixedly connected to the top of the scraper 16; a fixed head 51 is fixedly connected to the top of the elastic rod 5; and a plurality of fixed columns 52 are fixedly connected to the middle part of the inner side of the dust hopper 1; during operation, when the impurities on the inner wall of the dust hopper 1 are brushed off by the rotation of the scraper 16, the fixed head 51 will rotate with the rotating plate 6. During the rotation, the fixed head 51 will contact the fixed column 52, and then the elastic rod 5 will be squeezed and bent. After the fixed head 51 passes the fixed column 52, the fixed head 51 will rebound and shake under the elastic force of the elastic rod 5, and then hit the next fixed column 52 passing by, causing the fixed column 52 and the fixed head 51 to vibrate, thereby driving the dust hopper 1 and the scraper 16 to vibrate, so that some of the residual dust can be vibrated off. Through the above structure, the residual impurities inside the dust hopper 1 can be further reduced, and the possibility of corrosion to the equipment by the residual impurities can be further reduced.

[0027] like Figure 1 to Figure 2 As shown, the middle part of the connecting rod 15 is rotatably connected to the rotating plate 6; the bottom of the side wall of the rotating plate 6 is fixedly connected to a limiting rope 61; the other end of the limiting rope 61 is fixedly connected to another middle part of the same group of connecting rods 15; during operation, when the connecting rod 15 rotates, the rotating plate 6 will be tilted due to the obstruction of the air, and at the same time, the bottom of the rotating plate 6 will be limited by the limiting rope 61, so that the inclination of the rotating plate 6 can only reach a certain angle. As the rotating plate 6 rotates, the rotating plate 6 will drive the air to flow downward, and then the flowing air carries the residual dust and is discharged from the dust collecting hopper 1 through the exhaust port 17. Through the above structure, the discharge speed of the dust inside the dust collecting hopper 1 can be accelerated.

[0028] like Figure 2 As shown, a gasket 7 is fixed to the middle of the fixing column 52; the fixing head 51 is made of colloid material; during operation, when the fixing head 51 collides with the fixing column 52, the fixing head 51 will hit the surface of the gasket 7. Since both are made of colloid material, the noise generated is greatly reduced. Through the above structure, the noise generated when the fixing head 51 collides with the fixing column 52 can be reduced.

[0029] During operation, after the impurities accumulated inside the dust hopper 1 are discharged through the impurity discharge port 17 at the bottom of the dust hopper 1, the motor 13 is started to drive the shaft column 14 to rotate, and then drive the multiple connecting rods 15 and the scraper 16 to rotate, so that the side wall of the scraper 16 scrapes the inner wall of the dust hopper 1, and then the impurities and chemical particles remaining on the inner wall of the dust hopper 1 are scraped off and discharged, so that these residual substances will not adhere to the inner wall of the dust hopper 1 for a long time and cause corrosion to the dust hopper 1. When there is no impurity accumulation inside the dust hopper 1, the fixed cylinder 23 will be in the middle of the impurity discharge port 17 close to the top of the impurity discharge port 17 under the pulling force of the baffle 22. Due to the cooperation of the fixed cylinder 23 and the sliding column 24, the baffle 22 will always remain parallel to the end face of the impurity discharge port 17. After the mechanical dust collector has been working for a period of time, some impurities will accumulate inside the dust hopper 1. At this time, these impurities will be pressed on the top of the baffle 22. As the amount of accumulated dust gradually increases, the baffle 22 will gradually move toward the bottom of the impurity discharge port 17, so that the operator can judge the amount of impurities accumulated inside the dust hopper 1 by simple observation. After the operator determines that the dust inside the dust hopper 1 has reached a certain amount, the baffle 22 can be pulled downward to disengage the baffle 22 from the bottom of the impurity discharge port 17. At this time, the dust accumulated inside the dust hopper 1 can be discharged from the impurity discharge port 17. When it is necessary to pull down the motor 13 to discharge the dust inside the dust hopper 1, the pull rope 33 can be pulled around the middle of the pulley 32, and then pulled horizontally. The pull rope 33 pulls the baffle 22 out of the interior of the discharge port 17, so that the dust accumulated in the dust hopper 1 will not fall on the operator's hands when it is discharged from the bottom of the discharge port 17. When the dust in the dust hopper 1 is discharged by pulling the pull rope 33, the round head 4 is passed through the first slot 41 near the top of the second fixing plate 31, and then the pull rope 33 is released to make the pull rope 33 fall into the first slot 41. The first slot 41 will clamp the round head 4, so that the pull rope 33 continues to pull the baffle 22, so that the baffle 22 will not rebound into the interior of the discharge port 17 under the pulling force of the spring 21, thereby continuously discharging the dust in the dust hopper 1. After the discharge is completed, the round head 4 is taken out from the upper first slot 41 and then put into the lower first slot 41. , so that the baffle 22 can slide into the interior of the impurity discharge port 17. When the impurities on the inner wall of the dust hopper 1 are brushed off by the rotation of the scraper 16, the fixed head 51 will rotate with the rotating plate 6. During the rotation, the fixed head 51 will contact the fixed column 52, and then the elastic rod 5 will be squeezed and bent. After the fixed head 51 passes the fixed column 52, the fixed head 51 will rebound and shake under the elastic force of the elastic rod 5, and then hit the next fixed column 52 passing by, so that the fixed column 52 and the fixed head 51 vibrate, and then drive the dust hopper 1 and the scraper 16 to vibrate, so that some of the residual dust can be vibrated off. When the connecting rod 15 rotates, the rotating plate 6 will tilt due to the obstruction of the air, and at the same time, the bottom of the rotating plate 6 will be limited by the limiting rope 61.The inclination of the rotating plate 6 can only reach a certain angle. As the rotating plate 6 rotates, the rotating plate 6 drives the air to flow downward, and then the flowing air carries the residual dust and is discharged from the interior of the dust collecting hopper 1 through the impurity discharge port 17.
