[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a steel truss processing and conveying device, such as... Figures 1-6As shown, the system includes a worktable 1. A support block 11 is fixedly connected to the top of the outer wall of the worktable 1. A servo motor 12 is fixedly connected to the top of the outer wall of the support block 11. A pair of first fixed frames 13 are fixedly connected to the top of the outer wall of the worktable 1. A lower straightening wheel 14 is rotatably connected to the inner wall of the first fixed frame 13. An upper straightening wheel 15 is rotatably connected to the inner wall of the first fixed frame 13. A first gear 16 is fixedly connected to the outer wall of the lower straightening wheel 14. A second gear 17 is fixedly connected to the outer wall of the upper straightening wheel 15. The output end of the servo motor 12 is connected to the lower straightening wheel 14. A first synchronous pulley 18 is fixedly connected to the side wall. A pair of second fixed frames 19 are fixedly connected to the top of the outer side wall of the worktable 1. A first cleaning brush 10 is rotatably connected to the inner side wall of the second fixed frame 19. A second cleaning brush 101 is rotatably connected to the inner side wall of the second fixed frame 19. A second synchronous pulley 105 is fixedly connected to the outer side wall of the first cleaning brush 10. The first synchronous pulley 18 is connected to the second synchronous pulley 105 through a synchronous belt 102. A third gear 103 is fixedly connected to the outer side wall of the first cleaning brush 10. A fourth gear 104 is fixedly connected to the outer side wall of the second cleaning brush 101. The web reinforcement bar is placed between the lower straightening wheel 14 and the upper straightening wheel 15. The servo motor 12 is started, which drives the lower straightening wheel 14 to rotate. The first gear 16 and the first synchronous wheel 18 also rotate, and the second gear 17, which meshes with the first gear 16, also rotates. This causes the lower straightening wheel 14 and the upper straightening wheel 15 to rotate relative to each other, straightening the web reinforcement bar. At the same time, the reinforcement bar is conveyed to the next stage. The first synchronous wheel 18 drives the second synchronous wheel 105 to rotate through the synchronous belt 102. Through the meshing between the third gear 103 and the fourth gear 104, the first cleaning brush 10 and the second cleaning brush 101 rotate relative to each other, cleaning impurities on the surface of the reinforcement bar. By setting the first cleaning brush 10 and the second cleaning brush 101, the reinforcement bar is cleaned to a certain extent while being conveyed and straightened, reducing the possibility of subsequent welding quality deterioration due to impurities and increasing the yield rate of subsequent equipment production.

[0029] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a filter screen 2 is provided on the inner side wall of the workbench 1, a fixed cover 21 is fixedly connected to the top of the outer side wall of the workbench 1, and a fixed frame 22 is fixedly connected to the bottom of the outer side wall of the workbench 1. A slide bar 23 is slidably connected to the inner side wall of the fixed frame 22, and a collection box 24 is fixedly connected to the side wall of the slide bar 23. An inclined plate 25 is fixedly connected to the inner side wall of the collection box 24. Before the equipment starts working, the collection box 24 is slid into the fixed frame 22 through the slide bar 23. At this time, the collection box 24 is located below the filter screen 2. The second cleaning brush 101 and the first cleaning brush 10 will continuously sweep dust and debris towards the fixed cover 21. Due to the obstruction of the fixed cover 21, these impurities will fall downwards, pass through the filter screen 2 and fall into the collection box 24. Finally, they will accumulate in the middle of the collection box 24 through the inclined plate 25. The collection box 24 and the fixed cover 21 facilitate the collection of dust and debris by the staff, reduce the situation where scattered debris re-attaches to the steel bars, and facilitate the use of the equipment by the staff.

[0030] like Figure 1 and Figure 4 As shown, a pair of support frames 3 are fixed to the top of the outer wall of the workbench 1. A buckle plate 31 is installed on the top of the outer wall of the support frame 3, and several contact rollers 32 are in contact with the top of the outer wall of the support frame 3. The support frame 3 is bolted to the buckle plate 31 by fixing bolts 33. Before the equipment operates, several contact rollers are placed on top of the support frame 3, and the buckle plate 31 is placed on top of the support frame 3. The two are then fixed together by fixing bolts 33, thereby fixing the contact rollers 32. Reinforcing bars pass over the contact rollers 32. When the reinforcing bars move, the contact rollers 32 rotate accordingly. The contact rollers 32 provide support for the reinforcing bars, increasing their stability during movement.

[0031] like Figure 1 and Figure 3 As shown, a connecting post 4 slides in contact with the side wall of the collection box 24. A connecting plate 41 is fixed to one end of the connecting post 4, and a contact plate 42 is fixed to the other end. The connecting plate 41 contacts the collection box 24. When the equipment is working, a certain amount of debris and other impurities will accumulate inside the collection box 24. When the operator pulls the contact plate 42, the connecting post 4 moves. At this time, the connecting plate 41 pushes the accumulated debris flat. The connecting post 4 and the connecting plate 41 facilitate the operator's cleaning of debris inside the collection box 24, reducing the frequency of the operator emptying the collection box 24.

[0032] like Figure 5As shown, a fixing block 5 is fixedly attached to the bottom of the outer wall of the workbench 1. The side wall of the fixing block 5 slides in contact with a limiting strip 51, which in turn contacts the fixing frame 22 and the slide bar 23. When the equipment is working, after the collection box 24 is installed, the limiting strip 51 is pushed to contact the slide bar 23. At this time, the limiting strip 51 restricts the slide bar 23 to a certain extent, thereby fixing the collection box 24. The limiting strip 51 facilitates the quick fixing of the collection box 24 by the operator, reducing the possibility of the collection box 24 moving during equipment operation.

[0033] like Figure 6 As shown, several ball bearings 6 are provided on the inner side wall of the fixed frame 22, and the ball bearings 6 are in contact with the slide bar 23. When the equipment is working, the operator will pull the collection box 24. At this time, the slide bar 23 will come into contact with the fixed frame 22. The ball bearings 6 can change the sliding friction between the slide bar 23 and the fixed frame 22 into rolling friction. The ball bearings 6 make it easier for the operator to use the equipment.

[0034] like Figure 3 As shown, an observation plate 7 is provided on the side wall of the collection box 24. The observation plate 7 is made of transparent material. When the equipment is working, the staff can quickly understand the accumulation inside the collection box 24 through the observation plate 7. The observation plate 7 facilitates the staff to observe the inside of the collection box 24 at any time, so as to empty the debris inside the collection box 24.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
