[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1As shown, a steel bar rust removal device for road and bridge construction includes a base 1, a shell 2 is fixedly connected to the middle side of the upper rear end of the base 1, two fixed bars 5 are fixedly connected to the upper left end of the base 1, a dust suction device 6 is slidably connected to the front side of the lower part of the base 1, a rectangular groove is opened on the middle side of the upper left end of the base 1, and a conveying device 4 is rotatably connected between the inner surface of the rectangular groove and the two fixed bars 5.

[0028] The device can be powered by an external power source.

[0029] Before the implementation of this device, the equipment needs to be placed on a flat ground, and then the conveying device 4 and the rust removal device 3 are started by the power supply, and then the steel bars that need to be rusted are sent from the conveying device 4, and the conveying device 4 then sends the steel bars into the rust removal device 3 for rust removal, and then sent out through the conveying device 4;

[0030] The dust collecting device 6 of the device can collect and store the removed rust and iron, and then discharge them uniformly, thereby improving work efficiency.

[0031] Specifically, how the rust removal device 3 removes rust from the steel bar, see Figure 2 The rust removal device 3 includes four roller brushes 35 and a support plate 34. The four roller brushes 35 are rotatably connected to the front and rear upper ends of the base 1 and the top wall of the shell 2. The four roller brushes 35 are rotatably connected to the upper end of the base 1 and the top wall of the shell 2. The upper portion of the outer surface of the four roller brushes 35 is fixedly connected to a pulley 31. A transmission belt 32 is commonly wound around the four pulleys 31. The support plate 34 is fixedly connected to the left side of the front upper end of the shell 2. The rear upper end of the support plate 34 is rotatably connected to a circular motor 33. The output end of the circular motor 33 is fixedly connected to one of the roller brushes 35.

[0032] In the above, the circular motor 33 drives the roller brush 35 to rotate through the coupling, and the rear roller brush 35 drives the pulley 1 31 fixed to it to rotate, and then transmits power to the remaining pulleys 1 31 through the transmission belt 1 32. The pulley 1 31 then transmits power to the roller brush 35 connected to it to perform rust removal. This rust removal efficiency is high and the working cost is low.

[0033] In the above, the roller brush 35 is composed of a roller and a steel brush, which can quickly process the rust on the surface of the steel bar.

[0034] Specifically, how the steel bars are fed into the housing 2 through the conveying device 4 is described in detail. Figure 3The conveying device 4 includes a support seat 47 and two rotating rods 42. A rectangular groove is opened in the middle side of the upper right part of the base 1. The two rotating rods 42 are symmetrically connected to the front wall and rear wall of the rectangular groove. The support seat 47 is fixedly connected to the front side of the upper left part of the base 1. The upper end of the support seat 47 is fixedly connected to the driving motor 46. Two transmission rods 45 are symmetrically arranged at the upper and lower parts of the rear of the driving motor 46. The driving motor 46 is rotatably connected to the upper transmission rod 45. The middle part of the outer surface of the two transmission rods 45 is fixedly connected to the input component 48. The rear part of the outer surface of the transmission rod 45 connected to the driving motor 46 is fixedly connected to the second pulley 43. The middle part of the outer surface of the two rotating rods 42 is fixedly connected to the output component 41. The rear part of the outer surface of the upper rotating rod 42 is fixedly connected to the second pulley 43. The two pulleys 43 are connected with a transmission belt 2 44 wrapped around them.

[0035] In the above description, the two input assemblies 48 are respectively composed of a left-right symmetrical rubber wheel 1 and a gear 1. The right rubber wheel 1 and the gear 1 are fixedly connected to the outer surface of the transmission rod 45. The upper and lower gears 1 are meshed with each other. The inner surfaces of the right rubber wheel 1 and the gear 1 are fixedly connected to a column. The column is rotatably connected between the rectangular groove and the fixed column 5. The upper transmission rod 45 and the front surface of the column are fixedly connected by a pulley. The two pulleys are connected by a belt wrapped around each other.

[0036] Similarly, the two output assemblies 41 are composed of a rubber wheel 2 and a gear 2, and the two output assemblies 41 are meshed and transmitted through the gear 2;

[0037] In the above, the driving motor 46 drives the transmission rod 45 fixedly connected to it to rotate clockwise through the coupling, and the transmission rod 45 transmits power to the rubber wheel 1 and gear 1 on the outer surface. The transmission rod 45 transmits power to the column on the upper right side through the pulley and the belt. The column then drives the rubber wheel 1 and gear 1 on the outer surface to rotate, and then transmits power to the gear 1 located at the lower part through the gear 1 located at the upper part. Through the action of the gears meshing, the transmission rod 45 and the column at the lower part are driven to rotate clockwise, thereby achieving the purpose of feeding the steel bars into the conveyor 4 for rust removal;

[0038] Next, the transmission rod 45 at the top transmits the power to the upper rotating rod 42 through the pulley 2 43 and the transmission belt 2 44, causing the upper rotating rod 42 to rotate clockwise. Then, the two gears 2 are engaged, driving the lower rubber wheel 2 and gear 2 to rotate, thus delivering the derusted steel bars.

[0039] Among the above, the rubber wheel is an existing technology, has strong elasticity and friction, can be better adapted to steel bars of different diameters, and improves the practicability of the device.

[0040] Specifically, how the dust collecting device 6 achieves the purpose of collecting rust iron, see Figure 4 A rectangular groove is provided at the lower front end of the base 1, and the storage device 62 is slidably connected to the inner surface of the rectangular groove. A groove is provided in the middle of the front end of the storage device 62, and a filter element 63 is detachably connected to the inner surface of the groove. A centrifugal fan 61 is installed in the middle of the rear end of the storage device 62.

[0041] In the above description, the centrifugal fan 61 is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine that accelerates the gas through a high-speed rotating impeller, then decelerates and changes the flow direction, thereby converting kinetic energy into potential energy pressure.

[0042] In the above, a trapezoidal groove is opened in the middle of the upper end of the base 1, and a circular hole is opened in the bottom wall of the trapezoidal groove. The rust iron slides down to the bottom wall through the inclined surface of the trapezoidal groove, and the centrifugal fan 61 then sucks the rust iron through the circular hole and blows it into the storage device 62;

[0043] In the above, the filter element 63 is composed of a plastic grid and filter cotton, wherein the filter cotton is the core part and is responsible for the actual filtering work, which can ensure that the gas is circulated and discharged while the rust and iron will not fly out of the storage device 62;

[0044] In the above, the plastic grille can be installed in the inner cavity of the rectangular groove by its own friction. When it needs to be removed or installed, it is only necessary to pull the plastic grille out of the inner cavity of the rectangular groove or press the plastic grille into the rectangular groove with force. It can be fixed by the friction between the inner surface of the rectangular groove and the plastic grille.

[0045] Similarly, how the storage device 62 collects and discharges, see Figure 5 and Figure 6 The storage device 62 includes a box body 621, which is slidably connected to the inner surface of the rectangular groove. A hopper 623 is fixedly connected to the inside of the box body 621. A rectangular hole is opened in the middle side of the bottom wall of the hopper 623. The rear wall of the rectangular hole is rotatably connected to a connecting column 627. The outer surface of the connecting column 627 is fixedly connected to an active plate 626. The rear part of the upper end of the active plate 626 and the lower part of the rear wall of the hopper 623 are jointly fixedly connected to an elastic plate 625.

[0046] In the above description, a trapezoidal hole is opened in the middle of the rear wall of the box body 621, and the output end of the centrifugal fan 61 blows the rust iron into the surface of the drop hopper 623 through the trapezoidal hole for collection. Due to the design of the slope of the drop hopper 623, the rust iron can slide down and accumulate on the upper part of the active plate 626. When it needs to be discharged, the storage device 62 is pulled out through the handrail fixedly connected to the front end of the box body 621. Due to gravity, the active plate 626 rotates downward with the connecting column 627 as the center of the circle to discharge the rust iron. After the discharge, the elastic plate 625 will pull the active plate 626 upward to close it, and then push the storage device 62 back to its original position through the handrail.

[0047] It should be noted that the specific installation method, circuit connection method and control method of the circular motor 33, drive motor 46 and centrifugal fan 61 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
