DETAILED DESCRIPTION

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model provides a device for removing rust from the surface of a conical hub. Figure 1-5 As shown, the device for removing rust from the surface of a cone hub includes: a box body 1 with a discharge port at the bottom; a rotating shaft 2 rotatably installed on one side of the box body 1; a motor 3 installed on one side of the box body 1, and the output shaft of the motor 3 is fixedly connected to one end of the rotating shaft 2; a shell 4 fixedly installed on the discharge port for collecting impurities; a fixing mechanism mounted on the rotating shaft 2 for fixing the cone hub 5; a sandblasting mechanism mounted on the box body 1 for rust removal; and a gas filtering mechanism mounted on the box body 1 for dust reduction.

[0024] It should be noted that in the prior art, people often use hand-held sandblasting guns to remove rust from the cone hub. Although the rust on the surface of the cone hub can be removed, it is impossible to manually remove rust from multiple cone hubs at the same time, resulting in the cone hubs having to be removed one by one. The work efficiency is low, and a lot of fine ash will be generated during the rust removal process. These fine ash are light in weight and can easily float in the air, and can easily be inhaled into the human body and enter the artificial eye, causing considerable harm to the human body.

[0025] In the scheme, when the device is used to remove rust from the cone hub 5, a fixing mechanism is required to fix multiple cone hubs 5 to be removed from rust. After fixing, the motor 3 is started, and the motor 3 will drive the rotating shaft 2 to rotate, and the rotating shaft 2 will drive the fixing mechanism to rotate, so that the multiple cone hubs 5 will rotate. Then the sandblasting mechanism can be used to remove rust from the multiple cone hubs 5 at the same time, and the treatment effect is better and the work efficiency is better. During the rust removal process, the waste and impurities generated will fall into the shell 4 for collection. During the rust removal process, the gas filtering mechanism needs to be started to filter and replace the gas in the box 1, and the fine ash contained in the gas is sucked into the shell 4 for collection. Since the entire rust removal process is completed inside the box 1, the fine ash generated is not easily inhaled into the human body and enters the artificial eye, and it is safer to use.

[0026] In a further preferred embodiment of the utility model, the fixing mechanism includes: a mounting plate 6 welded on the rotating shaft 2, a slide groove being opened on one side of the mounting plate 6; a bidirectional screw 7 rotatably mounted on the inner walls on both sides of the slide groove, both ends of the bidirectional screw 7 extending to the outside of the mounting plate 6; two sliders 8 threadedly mounted on the bidirectional screw 7, both sliders 8 being slidably connected to the inner wall of the slide groove; and fixing rods 9 respectively fixedly mounted on the two sliders 8.

[0027] In this embodiment, the fixing mechanism is used to fix the conical hub 5. When fixing, the conical hub 5 is placed on two fixing rods 9, and then the bidirectional screw 7 is rotated. The bidirectional screw 7 will drive the two sliders 8 away from each other, and the two sliders 8 will drive the two fixing rods 9 away from each other, so that the two fixing rods 9 are tightly contacted with the inner wall of the conical hub 5, so that the fixing work of the conical hub 5 can be completed.

[0028] In a further preferred embodiment of the utility model, the sandblasting mechanism includes: a plurality of material delivery pipes 10 slidably mounted on the top of the box body 1, the bottom ends of the plurality of material delivery pipes 10 are fixedly connected to a sandblasting gun 11; a connecting plate 12 fixedly mounted on the plurality of material delivery pipes 10; and a cylinder 13 welded on the top of the box body 1, the output rod of the cylinder 13 being fixedly connected to the bottom of the connecting plate 12.

[0029] In this embodiment, the sandblasting mechanism is used to remove surface rust on the cone hub 5. When in use, one end of the multiple feed pipes 10 needs to be connected to an external device, and the external device can continuously input abrasives into the sandblasting gun 11 through the multiple feed pipes 10 and spray them out. The sprayed abrasives will fall on the surfaces of the multiple cone hubs 5 to remove the rust on the surfaces of the multiple cone hubs 5. During this process, the cylinder 13 will drive the connecting plate 12 to move up and down, and the connecting plate 12 will drive the multiple feed pipes 10 and the multiple sandblasting guns 11 to move up and down, so that the abrasives sprayed by the multiple sandblasting guns 11 can fully remove the rust on the multiple cone hubs 5.

[0030] In a further preferred embodiment of the utility model, the gas filtering mechanism includes: a fan 14 welded to the bottom of the box body 1, an exhaust pipe 15 is fixedly installed on the air inlet end of the fan 14, and one end of the exhaust pipe 15 extends to the interior of the shell 4; a first filter 16 fixedly installed on the inner wall of the shell 4; a connecting pipe 17 fixedly installed on the exhaust end of the fan 14; a mounting pipe 18 threadedly installed on the connecting pipe 17, and a second filter 19 for filtering gas is fixedly installed on the mounting pipe 18.

[0031] In this embodiment, the gas filtering mechanism can filter and replace the gas in the box body 1. When in use, the fan 14 will absorb the gas in the shell body 4 through the exhaust pipe 15, so that the shell body 4 generates a negative pressure, and the gas in the box body 1 is sucked into the shell body 4. Then, these gases will be filtered by the first filter 16, and the fine ash impurities in the gas will be intercepted in the shell body 4. Then, these gases will enter the inside of the fan 14, and then be discharged from the fan 14 into the second filter 19. After the secondary filtration of the second filter 19, the quality of the gas discharged from the outside of the device can be guaranteed, and the content of fine ash in the box body 1 can be greatly reduced.

[0032] In a further preferred embodiment of the present invention, an air inlet is provided on the top of the box body 1, and a dustproof net 20 is fixedly installed on the top of the box body 1, and the dustproof net 20 is located above the air inlet.

[0033] In this embodiment, the use of the air inlet can provide gas into the box 1 to prevent insufficient gas in the box 1 from affecting the use of the gas filtering mechanism. The dustproof net 20 can prevent fine dust inside the box 1 from being discharged outside the device through the air inlet.

[0034] In a further preferred embodiment of the present invention, a support base 21 is fixedly installed on one side of the box body 1 , and the top of the support base 21 is fixedly connected to the bottom of the motor 3 .

[0035] In this embodiment, the support base 21 can play a role in fixing and supporting the motor 3 , so that the motor 3 is firmly fixed on one side of the box body 1 .

[0036] In a further preferred embodiment of the present invention, a material taking port is provided on one side of the shell 4, and a first sealing door is provided on the material taking port.

[0037] In this embodiment, the impurities stored in the shell 4 can be conveniently taken out manually from the material taking port by opening the first sealing door.

[0038] In a further preferred embodiment of the utility model, an inlet and an outlet are provided on one side of the box body 1, a second sealing door is provided on the inlet and an observation port is provided on the second sealing door, and an observation window is fixedly installed on the inner wall of the observation port.

[0039] In this embodiment, the inlet and outlet and the second sealed door can be used to conveniently place the cone hub 5 into the box body 1, and it is also convenient to take the rust-removed cone hub 5 out of the box body 1. The observation port and the observation window can be used to conveniently check the internal conditions of the box body 1.

[0040] In summary, in the utility model, through the coordinated use of the rotating shaft 2, the motor 3, the fixing mechanism and the sandblasting mechanism, multiple cone hubs 5 can be rust-removed at the same time, the treatment effect is good, and the work efficiency is good. The gas in the box 1 can be filtered and replaced through the gas filtering mechanism, so as to ensure the gas quality outside the discharge device, and can greatly reduce the content of fine ash in the box 1. Since the entire rust removal process is completed inside the box 1, the fine ash generated is not easily inhaled into the human body and enters the artificial eye, and it is safer to use.

[0041] Compared with the related art, in this scheme, the inlet and outlet and the second sealed door can facilitate manual placement of the cone hub 5 into the casing 1, and can also facilitate removal of the cone hub 5 from the casing 1 after rust removal. The observation port and the observation window can facilitate manual observation of the internal situation of the casing 1. The fixing mechanism can fix multiple cone hubs 5 to be rust-free, and the starting of the motor 3 can make the multiple cone hubs 5 rotate after being fixed. The sandblasting mechanism can simultaneously perform rust removal on multiple cone hubs 5, and the treatment effect is good and the work efficiency is good. The gas filtering mechanism can greatly reduce the content of fine ash in the casing 1. Since the entire rust removal treatment is completed inside the casing 1, the fine ash generated is not easily inhaled into the body and enters the artificial eye, and is safer to use. Gas can be provided to the casing 1 through the air inlet to prevent insufficient gas in the casing 1 from affecting the use of the gas filtering mechanism. The dustproof net 20 can prevent the fine ash inside the casing 1 from being discharged from the air inlet to the outside of the device. By opening the first sealed door, it is convenient for manual labor to remove impurities stored in the shell 4 from the material taking port.
