[0032] Sliding mechanism 7 is slidingly connected to the upper end of workbench 6, and a rectangular hole is formed in the middle side of the lower part of the outer surface of outer cylinder 1.

[0033] When the device needs to remove rust from the steel bar, the device can be moved by pull rod 2, the device is placed on workbench 6, the steel bar is inserted into rust removal assembly 8 from the fixing device 3 located at the front, and the rust removal assembly 8 is further clamped and fixed to the steel bar, and the fixing device 3 located at the rear is inserted out of the rust removal assembly 8.

[0034] In the above, after the steel bar is inserted into the device, the steel bar is fixed on the workbench 6, so that the steel bar does not move during rust removal, and the fixing method can be fixed according to the fixing method required by the operator, which will not be described in detail herein.

[0035] In the above, after the steel bar is fixed, the push rod 4 is pulled to move the device on the upper end of the workbench 6 through the sliding mechanism 7, and the push rod 4 is pulled back and forth to move the rust removal assembly 8 through the outer cylinder 1, so that the rust removal assembly 8 removes rust from the steel bar, and the rust removal assembly 8 also brushes the rust powder off the steel bar during rust removal, at this time, the dust removal device 5 is started to work, so that the dust removal device 5 performs vacuum cleaning to collect the rust powder in the dust removal device 5;

[0036] In the above, if the dust removal device 5 is full of rust powder, the dust removal device 5 can be taken out and the collected rust powder can be poured out.

[0037] In the above, the fixing device 3 is a telescopic clamping, so that the fixing device 3 can be suitable for steel bars of different diameters, thereby increasing the diversity of the device.

[0038] In the above, the sliding mechanism 7 is composed of a support column and a pulley, the support column is fixedly connected to the lower part of the outer surface of the outer cylinder 1, and the pulley is fixedly connected to the lower end of the support column, and the device slides on the upper end of the workbench 6 through the pulley.

[0039] In addition, the device does not need additional mechanical power source during implementation, so that the device can be pushed back and forth by external force or manpower to remove rust from the steel bar, thereby making the device convenient and can be used at any time and any place.

[0040] Further, in order to achieve the purpose that the fixing device 3 can also make the reinforcing steel bar slide inside when fixing the reinforcing steel bar, referring to Figure 4 , the fixing device 3 comprises a fixing ring 31 and two fixing shells 32, the fixing ring 31 is fixedly connected to the front end of the outer cylinder 1, the two fixing shells 32 are respectively fixedly connected to the inner cavities of the upper and lower parts of the fixing ring 31, the inner cavities of the two fixing shells 32 are slidably connected with telescopic rods 35, the parts of the two telescopic rods 35 close to each other are rotatably connected with rubber wheels 34, and the walls of the two fixing shells 32 away from each other and the ends of the two telescopic rods 35 away from each other are respectively fixedly connected with telescopic springs 33.

[0041] In the above, the reinforcing steel bar passes between the two rubber wheels 34, and the tension generated by the reinforcing steel bar drives the rubber wheels 34 to push the two telescopic rods 35 to slide in the inner cavities of the fixing shells 32 away from each other, when the telescopic rods 35 slide in the inner cavities of the fixing shells 32, the telescopic springs 33 are squeezed to generate pressure, and under the action of the telescopic springs 33, when the reinforcing steel bar is completely arranged in the device, the telescopic springs 33 will push the telescopic rods 35 to move to the part close to each other through the squeezing pressure, thereby achieving the purpose of clamping the reinforcing steel bar.

[0042] In the above, when the device is moved by the push rod 4, the rubber wheel 34 will rotate and move on the surface of the reinforcing steel bar, so that the rubber wheel 34 moves with the device, and then the rust removal assembly 8 removes the rust on the reinforcing steel bar.

[0043] In addition, when the middle position of the reinforcing steel bar is lifted, the two sides of the lifted part of the reinforcing steel bar will naturally sag to form a local protrusion, so in the implementation process, the reinforcing steel support in the prior art can also be used to lift the reinforcing steel bar, so that the reinforcing steel bar is at the same height as the rubber wheel 34 in the present application, which can effectively reduce the resistance generated by the reinforcing steel bar on the device.

[0044] Generally, the reinforcing steel bars with larger usage in construction sites are smaller in diameter, for example: φ6, φ8, φ10, φ12, φ14, φ16 and φ20.

[0045] Further, in order to achieve the purpose that the rust powder brushed off from the surface of the reinforcing steel bar by the rust removal assembly 8 can also be swept, referring to Figure 5 and Figure 6 , the rust removal assembly 8 comprises six fixed rods 81 and two brushes 82, the six fixed rods 81 are respectively fixedly connected to the front, middle and rear sides of the left and right parts of the inner cavity of the outer cylinder 1, the ends of the two fixed rods 81 on the same side close to each other are fixedly connected with a steel brush cylinder 83, and the two brushes 82 are respectively fixedly connected to the front and rear sides of the upper part of the inner cavity of the outer cylinder 1.

[0046] The two brushes 82 are respectively located in the gaps between the three steel brush cylinders 83.

[0047] The reinforcing steel bar is inserted into the steel brush cylinder 83 from the fixing device 3, so that the steel brush cylinder 83 removes rust from the reinforcing steel bar.

[0048] When the outer cylinder 1 is moved by the push rod 4, the steel brush cylinder 83 is moved by the fixing rod 81, so that the steel brush cylinder 83 brushes the surface of the reinforcing steel bar to remove rust, and the rust powder is left on the reinforcing steel bar, at this time, the brush 82 is moved with the outer cylinder 1, so that the brush 82 sweeps the rust powder on the reinforcing steel bar to the lower part of the outer cylinder 1, and the dust removal device 5 collects the rust powder.

[0049] Further, in order to achieve the purpose of collecting the rust powder removed by the rust removal assembly 8 by the dust removal device 5, referring to Figure 7 and Figure 8 The dust removal device 5 comprises a connecting column 53 fixedly connected to the lower middle side of the outer surface of the outer cylinder 1, the lower end of the connecting column 53 is fixedly connected with an outer shell 51, the inner cavity of the outer shell 51 is slidably connected with a collecting bin 52, and the upper end of the right part of the outer shell 51 is fixedly connected with a vacuum pump 54.

[0050] The outer cylinder 1 is communicated with the connecting column 53, and the connecting column 53 is communicated with the outer shell 51.

[0051] In the above, the vacuum pump 54 is started to work, so that the vacuum pump 54 extracts the inside of the outer shell 51 to a vacuum state, then the rust powder enters the connecting column 53 from the rectangular hole of the outer cylinder 1, and then the rust powder enters the collecting bin 52 from the connecting column 53, so that the collecting bin 52 collects the rust powder, so that the rust powder is not accumulated in the outer cylinder 1.

[0052] In the above, when the collecting bin 52 is full, the collecting bin 52 can be taken out of the outer shell 51, the rust powder in the collecting bin 52 is poured out, and then the collecting bin 52 is reloaded into the outer shell 51 to collect the rust powder.

[0053] In the above, the vacuum pump 54 is a device for generating, improving and maintaining a vacuum environment; it extracts gas molecules in a closed space by mechanical, physical or chemical methods, so as to reduce the air pressure in the space to reach a vacuum state, and the model can adopt the existing technology: VAP350 micro vacuum pump.

[0054] It should be particularly pointed out that the specific installation mode of the vacuum pump 54, the connection mode of the circuit and the control method used in the utility model all belong to conventional design, and the utility model will not be described in detail.
