[0028] 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.

[0029] like Figures 1 to 3As shown, an agricultural greenhouse steel pipe processing and welding machine according to an embodiment of the present invention includes a support base 1; a second support frame 2 is fixedly connected to the top of the support base 1; a sliding seat 3 is slidably connected to the interior of the second support frame 2; a rotating shaft 5 is rotatably connected to the interior of the sliding seat 3; a fixed frame 4 is fixed to the end of the rotating shaft 5; a grinding wheel 6 is installed inside the fixed frame 4 through a fixing assembly; a sliding frame 7 is fixed to the top of the fixed frame 4; a slide groove 8 is opened on the side wall of the sliding seat 3; the sliding frame 7 is slidably connected to the inside of the slide groove 8 Position; a plurality of first support frames 101 are fixedly connected to the top of the support base 1; a feed roller 102 is rotatably connected to the first support frame 101; a welding assembly is provided on the top of the support base 1, and the first support frame 101 is provided at positions on both sides of the welding assembly; a rotating assembly is provided on the top of the support base 1; during work, when it is necessary to weld the steel pipe, the two steel pipes can be respectively provided on both sides of the welding assembly, and the steel pipes are fed by the rotation of the feed roller 102, and then the ends of the two steel pipes are sent to the positions on both sides of the grinding wheel 6 The ends of the steel pipes on both sides are then ground by the grinding wheel 6, so that the welding surfaces of the two steel pipes can be more closely fitted. The connection of the two steel pipes can then be sent to the bottom of the welding assembly by the first support frame 101, and the steel pipes can be rotated by the rotating assembly, and the steel pipes are welded by the welding assembly. The grinding wheel 6 is set to grind the ends of the two steel pipes and trim the end faces of the steel pipes, which realizes the function of making the two steel pipes more closely fitted and making the steel pipe welding effect better, and effectively solves the problem of easy cracking on the cross section of the steel pipe. Burrs are retained. During the contact process between the two steel pipes, gaps are likely to remain between the two steel pipes, which may affect the welding effect of the steel pipes when the steel pipes are welded. At the same time, during the grinding process of the steel pipes, in order to increase the contact area of ​​the two steel pipes, the grinding wheel 6 can be tilted to grind the ends of the steel pipes. In order to tilt the grinding wheel 6, the fixed frame 4 can be controlled to drive the fixed assembly and the grinding wheel 6 to tilt. When the fixed frame 4 is tilted, the sliding frame 7 is limited by the slide groove 8, which can support the fixed frame 4 and make the fixed frame 4 more stable.

[0030] like Figure 1 and Figure 7As shown, the welding assembly includes a support seat 9; a sliding plate 10 is provided on the top of the support seat 9; a plurality of electric push rods are fixed to the top of the sliding plate 10, and the output ends of the electric push rods pass through the sliding plate 10 and are fixed to the top position of the support seat 9; a slide rail 11 is fixed to the top of the sliding plate 10; a sliding block 12 is slidably connected to the inside of the slide rail 11; the sliding of the sliding block 12 is driven by an electric wheel; a welding gun is installed inside the sliding block 12, and the welding gun is facing the position of the support base 1; during work, when it is necessary to weld the steel pipe, When welding, the connection of the steel pipe can be transported to the position at the bottom of the corresponding slide rail 11, and then the sliding plate 10 can be controlled to rise or fall on the top of the support seat 9, and the connection of the two steel pipes can be welded by the welding gun. At the same time, the steel pipe can be driven to rotate by the rotating assembly, and then the steel pipe is welded. During the welding process, in order to control the sliding of the sliding block 12, an electric wheel can be installed on the sliding block 12 to control the sliding of the sliding block 12. When the connection of the steel pipe is inclined, the steel pipe can also be welded, making the welding of the steel pipe more convenient.

[0031] like Figure 1 and Figure 6 As shown, the rotating assembly includes a third support frame 13; the third support frame 13 is arranged on both sides of the second support frame 2; a mounting frame 14 is fixedly connected to the side wall of one of the third support frames 13; the internal rotation of the mounting frame 14 is connected to a driving wheel 15; the third support frame 13 is rotatably connected to two rotating wheels 16; the ends of the rotating shafts of the rotating wheels 16 are fixedly connected to driven wheels 17, and a transmission belt 18 is connected between the driven wheel 17 and the driving wheel 15; a connecting rod 19 is fixedly connected between the two driving wheels 15; during work, when it is necessary to weld the steel pipe, the steel pipe can be brought into contact with the rotating wheel 16, and then during the welding process, the driving wheel 15 can be controlled to rotate, and then the driven wheel 17 and the rotating wheel 16 can be driven to rotate by the transmission belt 18, so that the rotating wheel 16 drives the steel pipe to rotate through friction, and then the steel pipe can be rotated during the welding process, thereby making the welding of the steel pipe more convenient.

[0032] like Figures 2 to 3 As shown, the fixing assembly includes a fixing plate 20; the fixing plate 20 is provided on both sides of the grinding wheel 6; the grinding wheel 6 and the fixing plate 20 are connected by bolts; during operation, by providing the fixing plates 20 on both sides of the grinding wheel 6 and fixing the grinding wheel 6 and the fixing plates 20 by bolts, the replacement and disassembly of the grinding wheel 6 can be made more convenient.

[0033] like Figure 4As shown, the first support frame 101 is internally slidably connected to a sliding rod 21; a spring is fixed between the bottom of the sliding rod 21 and the inner side wall of the first support frame 101; a pressure roller 22 is rotatably connected to the sliding rod 21; the pressure roller 22 is arranged at a position corresponding to the top of the feed roller 102; during operation, in the process of conveying the steel pipe by rotating the feed roller 102, the steel pipe can be placed between the feed roller 102 and the pressure roller 22, and then the sliding rod 21 is pulled by the spring, so that the pressure roller 22 and the steel pipe can be fitted together, and in the process of conveying, rotating and welding the steel pipe, the steel pipe is squeezed by the pressure roller 22, so that the steel pipe can be placed more stably.

[0034] like Figures 4 and 5 As shown, the feed roller 102 and the pressure roller 22 are both rotatably connected to a plurality of groups of rollers 23, each group of rollers 23 is composed of two rollers 23, and a connecting belt 24 is connected between each group of rollers 23; the connecting belts 24 are regularly arranged in a circular array inside the feed roller 102 and the pressure roller 22; the direction of the connecting belt 24 is perpendicular to the rotation direction of the slide rail 11; during operation, in the process of rotating the steel pipe, by setting the connecting belt 24 to contact the steel pipe, the friction between the steel pipe and the feed roller 102 and the pressure roller 22 can be made smaller, thereby effectively avoiding excessive friction between the feed roller 102, the pressure roller 22 and the steel pipe, which makes the steel pipe unable to rotate.

[0035] like Figure 4 As shown, a guide block 25 is fixed to the side wall of the sliding rod 21; the guide block 25 is slidably connected to the internal position of the first support frame 101; during operation, when the sliding rod 21 slides inside the first support frame 101, the sliding of the guide block 25 is restricted by the first support frame 101, so that the sliding rod 21 is less likely to tilt during the sliding process, making the sliding of the sliding rod 21 more stable.

[0036] like Figure 3 As shown, a splash plate 26 is connected to the side wall of the fixing frame 4 by bolts; the splash plate 26 is arranged at the side position of the grinding wheel 6; during operation, when the end of the steel pipe is ground by the grinding wheel 6, the splash plate 26 is arranged on the side of the fixing frame 4, so that the debris generated during the grinding process can be shielded, thereby effectively avoiding the occurrence of debris splashing.

[0037] like Figure 1 and Figure 7As shown, a water tank 27 is fixedly connected to the top of the support base 1; the water tank 27 is arranged at the position corresponding to the bottom of the grinding wheel 6 and the sliding plate 10; during operation, by arranging the water tank 27 on the top of the support base 1, water can be added to the inside of the water tank 27, and the metal particles generated during the grinding and welding process fall into the inside of the water tank 27, which can cool the metal particles and effectively prevent the metal particles from splashing and adhering to the surface of the support base 1, making it difficult to clean.

[0038] like Figure 3 As shown, a plurality of protrusions 28 are fixed to the side wall of the fixing plate 20; a groove 29 is provided on the side wall of the grinding wheel 6; the protrusions 28 and the grooves 29 are arranged correspondingly; during operation, after the grinding wheel 6 is fixed by the fixing plate 20, by providing the protrusions 28 on the side wall of the fixing plate 20 and fitting them into the grooves 29 on the side wall of the grinding wheel 6, the contact area between the grinding wheel 6 and the fixing plate 20 can be made larger, thereby making the fixing effect of the fixing plate 20 on the grinding wheel 6 better.

[0039] During operation, when it is necessary to weld the steel pipes, the two steel pipes can be respectively set on both sides of the welding assembly, and the steel pipes can be fed by the rotation of the feed roller 102, and then the ends of the two steel pipes are sent to the positions on both sides of the grinding wheel 6, and then the ends of the steel pipes on both sides are grinded by the grinding wheel 6, so that the welding surfaces of the two steel pipes can be more closely fitted, and then the connection of the two steel pipes can be sent to the position of the bottom of the welding assembly through the first support frame 101, and then the steel pipes can be rotated by the rotating assembly, and the steel pipes can be welded by the welding assembly, and the grinding wheel 6 is set to grind the ends of the two steel pipes and trim the end faces of the steel pipes, so that the structural design can be realized. The two steel pipes are made to fit more closely, which makes the welding effect of the steel pipes better. It effectively solves the problem that burrs are easily left on the cross-section of the steel pipe. In the process of contact between the two steel pipes, gaps are easily left between the two steel pipes, which leads to the problem that the welding effect of the steel pipes is easily affected when welding the steel pipes. At the same time, in the process of grinding the steel pipes, in order to increase the contact area of ​​the two steel pipes, the grinding wheel 6 can be tilted to grind the end of the steel pipe. In order to tilt the grinding wheel 6, the fixed frame 4 can be controlled to drive the fixed assembly and the grinding wheel 6 to tilt. When the fixed frame 4 is tilted, the sliding frame 7 is limited by the slide groove 8, and the fixed frame 4 can be supported to make the fixed frame 4 more stable.

[0040] When it is necessary to weld the steel pipes, the connection of the steel pipes can be transported to the position at the bottom of the corresponding slide rail 11. Then, the sliding plate 10 can be controlled to rise or fall on the top of the support seat 9, and the connection of the two steel pipes can be welded by a welding gun. At the same time, the steel pipes can be driven to rotate by the rotating assembly, and then the steel pipes can be welded. During the welding process, in order to control the sliding of the sliding block 12, an electric wheel can be installed on the sliding block 12 to control the sliding of the sliding block 12. When the connection of the steel pipe is inclined, the steel pipe can also be welded, making the welding of the steel pipe more convenient.

[0041] When the steel pipe needs to be welded, the steel pipe can be brought into contact with the rotating wheel 16. Then, during the welding process, the driving wheel 15 can be controlled to rotate, and then the driven wheel 17 and the rotating wheel 16 can be driven to rotate through the transmission belt 18, so that the rotating wheel 16 drives the steel pipe to rotate through friction, and then the steel pipe can be rotated during the welding process, which makes the welding of the steel pipe more convenient.

[0042] By arranging the fixing plates 20 on both sides of the grinding wheel 6 and fixing the grinding wheel 6 and the fixing plates 20 with bolts, the replacement and disassembly of the grinding wheel 6 can be made more convenient.

[0043] During the process of conveying the steel pipe by rotating the feed roller 102, the steel pipe can be placed between the feed roller 102 and the pressure roller 22. Then, the sliding rod 21 is pulled by the spring to make the pressure roller 22 fit with the steel pipe. During the process of conveying, rotating and welding the steel pipe, the steel pipe is squeezed by the pressure roller 22, so that the steel pipe can be placed more stably.

[0044] During the process of rotating the steel pipe, by setting the connecting belt 24 in contact with the steel pipe, the friction between the steel pipe and the feed roller 102 and the pressure roller 22 can be reduced, thereby effectively avoiding excessive friction between the feed roller 102 and the pressure roller 22 and the steel pipe, which causes the steel pipe to be unable to rotate.

[0045] When the sliding rod 21 slides inside the first support frame 101, the first support frame 101 restricts the sliding of the guide block 25, so that the sliding rod 21 is less likely to tilt during the sliding process, making the sliding of the sliding rod 21 more stable.

[0046] During the process of grinding the end of the steel pipe by the grinding wheel 6, by arranging the splash plate 26 on the side of the fixing frame 4, the debris generated during the grinding process can be shielded, thereby effectively avoiding the occurrence of debris splashing.

[0047] By setting a water tank 27 on the top of the support base 1 and adding water to the inside of the water tank 27, the metal particles generated during the grinding and welding process fall into the inside of the water tank 27, which can cool the metal particles and effectively prevent the metal particles from splashing and adhering to the surface of the support base 1, making it difficult to clean.

[0048] After the grinding wheel 6 is fixed by the fixing plate 20, by providing a protrusion 28 on the side wall of the fixing plate 20 to engage with the groove 29 on the side wall of the grinding wheel 6, the contact area between the grinding wheel 6 and the fixing plate 20 can be made larger, thereby making the fixing effect of the fixing plate 20 on the grinding wheel 6 better.
