[0019] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0020] Example 1: As Figure 1 、 Figure 2 、 Figure 3 、Figure 4 , Figure 5 , Figure 8 , Figure 12 As shown in Figure 8 , Figure 12 , ,

[0021] , a cutting device for steel pipes used in greenhouse greenhouses includes a cutting platform 1. A vertical plate 2 is fixedly arranged on the upper side of the cutting platform 1. A cutting mechanism 4 is arranged in the middle of one side of the vertical plate 2. The cutting mechanism 4 includes a fixed bracket 401 rotatably arranged on one side of the vertical plate 2. One end of the fixed bracket 401 is rotatably provided with a rotating shaft 402. A saw blade 406 is fixedly sleeved in the middle of the rotating shaft 402. A waste chip groove is opened in the middle of the cutting platform 1. The waste chip groove is located below the saw blade 406, which is convenient for discharging the waste chips generated by cutting. A protective cover 407 sleeved outside the saw blade 406 is fixedly arranged between the fixed brackets 401. The saw blade 406 can be protected by the protective cover 407, and the waste chips splashed by cutting can also be blocked, which is convenient for subsequent cleaning. A cutting servo motor 404 is fixedly arranged on one side of the protective cover 407. The output end of the cutting servo motor 404 is fixedly provided with a driving bevel gear 405. One side of the driving bevel gear 405 is engaged with a driven bevel gear 403 fixedly sleeved at one end of the rotating shaft 402. When in use, by driving the driving bevel gear 405 to rotate through the cutting servo motor 404, the driven bevel gear 403 can be driven to rotate, and then the rotating shaft 402 can be driven to rotate, so that the saw blade 406 in the middle of the rotating shaft 402 rotates, and the steel pipe can be cut. A through groove 410 is opened in the middle of the vertical plate 2. A fixed shaft 409 is horizontally fixedly arranged inside the through groove 410. A rotating cylinder 408 fixedly connected with the fixed bracket 401 is rotatably sleeved outside the fixed shaft 409. A connecting plate 411 is fixedly arranged on the side of the rotating cylinder 408 away from the fixed bracket 401. A bottom plate 413 is fixedly arranged on the rear side of the vertical plate 2. An adjusting cylinder 412 rotatably connected with the connecting plate 411 is rotatably arranged on the upper side of the bottom plate 413. When in use, by driving the connecting plate 411 to rotate through the adjusting cylinder 412, the rotating cylinder 408 can be driven to rotate around the fixed shaft 409, driving the fixed bracket 401 on the other side of the rotating cylinder 408 to rotate, and then driving the saw blade 406 on the fixed bracket 401 to rotate around the fixed shaft 409, so as to cut the steel pipe at different depths, ensure the smoothness of the cutting surface, and reduce the generation of burrs.

[0021] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown in the figure, on one side of the vertical plate 2, there are two clamping and rotating mechanisms 3 respectively located on both sides of the cutting mechanism 4. The clamping and rotating mechanism 3 includes a fixed disk 301 fixedly arranged on one side of the vertical plate 2. A steel pipe passage 313 is opened in the middle of the fixed disk 301, through which a steel pipe (not shown in the figure) can pass. At the lower part of one side of the fixed disk 301, a first semi-circular track 302 is fixedly arranged. The semi-circular arc surface of the first semi-circular track 302 is located below the steel pipe passage 313. On the upper part of one side of the fixed disk 301, a second semi-circular track 303 is slidably arranged above the first semi-circular track 302. The second semi-circular track 303 and the first semi-circular track 302 cooperate to form a complete circular track. Semi-circular sliding rings 304 are rotatably arranged on the inner sides of both the first semi-circular track 302 and the second semi-circular track 303. The first semi-circular track 302, the second semi-circular track 303, and the semi-circular sliding rings 304 are concentric with the steel pipe passage 313. When the first semi-circular track 302 and the second semi-circular track 303 are in contact, the two semi-circular sliding rings 304 form a circular sliding ring. A number of mounting posts 305 are fixedly arranged on the inner sides of both the two semi-circular sliding rings 304. At one end of each of the number of mounting posts 305 on the lower semi-circular sliding ring 304, a ball 306 is arranged. At one end of each of the number of mounting posts 305 on the upper semi-circular sliding ring 304, a rubber ball (not shown in the figure) is fixedly arranged. Through the rubber ball, the clamping of the steel pipe can be made more stable. The arc radius formed by the number of balls 306 is smaller than the radius of the steel pipe passage 313. Through the number of balls 306, it is convenient for the steel pipe to freely pass through the two steel pipe passages 313. A semi-circular gear ring 307 is fixed on the outer side of the semi-circular sliding ring 304. A rotary servo motor 309 is fixedly arranged on the upper side of the second semi-circular track 303. A driving gear 308 meshing with the semi-circular gear ring 307 is fixedly arranged at the output end of the rotary servo motor 309. During use, by driving the driving gear 308 to rotate through the rotary servo motor 309, the semi-circular gear ring 307 can be driven to slide inside the first semi-circular track 302, so that the clamped steel pipe rotates. A limiting groove 310 is vertically opened in the middle of the top end of the fixed disk 301. A limiting block 311 slidably connected to the inside of the limiting groove 310 is fixedly arranged at the rear side of the second semi-circular track 303. By sliding the limiting block 311 inside the limiting groove 310, a limiting effect can be exerted on the second semi-circular track 303. A clamping cylinder 312 is fixedly arranged on one side of the fixed disk 301. The output end of the clamping cylinder 312 is fixedly connected to the edge of the second semi-circular track 303. During use, when the steel pipe slides into the inside of the two steel pipe passages 313, by driving the second semi-circular track 303 to descend through the clamping cylinder 312, the second semi-circular track 303 can be made to fit on the upper side of the first semi-circular track 302. At this time, the second semi-circular track 303 and the two semi-circular sliding rings 304 inside the first semi-circular track 302 are made to fit to form a complete smooth sliding ring. At the same time, a number of mounting posts 305 and balls 306 inside the two semi-circular sliding rings 304 clamp the steel pipe.Since one side of the fixed disk 301 is close to the saw blade 406, the ball 306 is clamped on the side of the steel pipe section to be cut close to the cutting surface, which is convenient for the cut steel pipe section to overturn and fall to the side away from the saw blade 406 under uneven force. Then, the driving gear 308 is rotated by the rotating servo motor 309, driving the semi-circular gear ring 307 to slide inside the first semi-circular track 302, causing the two semi-circular sliding rings 304 to rotate inside the first semi-circular track 302 and the second semi-circular track 303, thereby driving the steel pipe to rotate, which is convenient for rotating cutting the steel pipe, so that the outer wall of the steel pipe is cut first, and then the inner wall is cut, so that the cutting surface on the outer surface of the steel pipe does not produce burrs, and at the same time, the burrs are located inside the cutting surface.

[0022] Embodiment 2: Further improvement based on Embodiment 1 lies in that, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 、 Figure 11 shown, a sliding plate 5 is slidably arranged on one side of the cutting platform 1, an electric telescopic rod 6 for driving the sliding plate 5 to slide is fixedly arranged on the edge of the cutting platform 1, a cooling and grinding mechanism 8 matching with the inside of the steel pipe is arranged in the middle of the sliding plate 5, a material discharging port 9 is opened in the middle of the cutting platform 1 and is located below the cooling and grinding mechanism 8, and a collecting box (not shown in the figure) is arranged below the material discharging port 9. Through the material discharging port 9, it is convenient for the cut steel pipe to automatically fall into the inside of the collecting box. The cooling and grinding mechanism 8 includes a fixed pipe 801 fixedly penetrating through the center of the sliding plate 5. One end of the fixed pipe 801 is fixedly communicated with a water inlet pipe 802. The water inlet pipe 802 is a flexible pipe. One end of the water inlet pipe 802 is connected with a water pump (not shown in the figure). Through the water pump, cleaning water can be pumped into the inside of the water inlet pipe 802. The other end of the fixed pipe 801 is fixedly communicated with a plurality of spray nozzles 803. Through the plurality of spray nozzles 803, the cutting surface and the saw blade 406 can be cooled, and the waste water can be discharged through the waste chip groove. One end of the fixed pipe 801 is fixedly sleeved with a grinding head 804 located on one side of the spray nozzles 803. When in use, by driving the sliding plate 5 to slide through the electric telescopic rod 6, the fixed pipe 801 in the middle of the sliding plate 5 can be inserted into the inside of the steel pipe, and then the grinding head 804 at one end of the fixed pipe 801 can be slidably inserted into the inside of the steel pipe. During the sliding insertion process, on the one hand, the rust on the inner wall of the rotating steel pipe can be ground, and on the other hand, the cutting surface inside the steel pipe can be ground through the grinding head 804 to remove the burrs on the cutting surface.

[0023] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 、 Figure 11As shown in the figure, on both sides of the skateboard 5, there are fixed-length adjusting and material-pushing mechanisms 7 located on both sides of the cooling and grinding mechanism 8. The fixed-length adjusting and material-pushing mechanism 7 includes a fixed rod 701 fixedly arranged on the upper side of the cutting platform 1. A through hole 704 is provided on one side of the skateboard 5. A push rod 702 that penetrates through the through hole 704 is slidably arranged at the upper end of the fixed rod 701. By means of the push rod 702, one end of the steel pipe can be pushed. On the one hand, the length of the steel pipe can be adjusted, and on the other hand, one end of the steel pipe can be abutted, which is convenient for the steel pipe to be discharged. A scale line 703 is arranged on one side of the push rod 702. A positioning knob 705 that abuts against the push rod 702 is threadedly penetrated through one side of the fixed rod 701. During use, by sliding the push rod 702, the push rod 702 can slide on the top end of the fixed rod 701, so that the scale line 703 on the push rod 702 moves on the upper end of the fixed rod 701. Then, the positioning knob 705 is tightened to make one end of the push rod 702 extend a certain length and be fixed. Since the two push rods 702 are respectively located on both sides of the fixed pipe 801, during the sliding process of the steel pipe inside the steel pipe channel 313, one end of the steel pipe can be abutted against one end of the push rod 702, so that the length of the steel pipe extending out of the saw blade 406 can be adjusted, thereby making the length of the steel pipe cut each time consistent, and the length of the steel pipe cut each time can also be adjusted according to different batches.

[0024] Embodiment 3: Further improvement based on Embodiment 2 lies in that, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10As shown in the figure, a feeding mechanism 10 is arranged on one side of the cutting platform 1. The feeding mechanism 10 includes a support frame 1001 arranged on one side of the cutting platform 1. A plurality of feeding rollers 1002 are rotatably arranged inside the support frame 1001 to improve the feeding accuracy of the steel pipe. In this embodiment, four feeding rollers 1002 are arranged, and the specific number can be flexibly adjusted according to the situation. The middle diameter of the feeding roller 1002 is small and the diameters at both ends are large, which is convenient for the steel pipe to be automatically centered during transportation and improve the transportation accuracy. One end of each of the plurality of feeding rollers 1002 is fixedly provided with a transmission shaft 1003 that rotatably penetrates the support frame 1001. Synchronous wheels 1005 are fixedly sleeved on the outer sides of the plurality of transmission shafts 1003. A synchronous belt 1004 is commonly engaged with the outer sides of the plurality of synchronous wheels 1005. A feeding servo motor 1006 for driving the transmission shaft 1003 to rotate is fixedly arranged on one side of the support frame 1001. During use, a steel pipe (not shown in the figure) is placed on the upper sides of the plurality of feeding rollers 1002, and then one of the transmission shafts 1003 is driven to rotate by the feeding servo motor 1006, and then the synchronous wheel 1005 on the outer side of the transmission shaft 1003 is driven to rotate. The plurality of synchronous wheels 1005 can be synchronously driven to rotate in the same direction through the synchronous belt 1004, and then the plurality of feeding rollers 1002 on one side of the plurality of synchronous wheels 1005 can be driven to rotate in the same direction, so that the steel pipe on the upper sides of the plurality of feeding rollers 1002 can be transported to the inside of the two steel pipe channels 313, which is convenient for subsequent cutting and improves the cutting efficiency.

[0025] It should be noted that for the cutting device of the steel pipe used in the greenhouse, during use, first, by sliding the ejector rod 702, the ejector rod 702 can slide on the top of the fixed rod 701, so that the scale line 703 on the ejector rod 702 moves on the upper end of the fixed rod 701. Then, tighten the positioning knob 705 to make one end of the ejector rod 702 extend a certain length and fix it. Then, place the whole steel pipe on the upper side of the plurality of feeding rollers 1002. Then, drive one of the transmission shafts 1003 to rotate by the feeding servo motor 1006, and then drive the synchronous pulley 1005 outside the transmission shaft 1003 to rotate. The synchronous belt 1004 can be used to synchronously drive a plurality of synchronous pulleys 1005 to rotate in the same direction, so that a plurality of feeding rollers 1002 on one side of the plurality of synchronous pulleys 1005 rotate in the same direction, and the steel pipe on the upper side of the plurality of feeding rollers 1002 can be conveyed to the inside of the two steel pipe channels 313. When one end of the steel pipe passes through the steel pipe channel 313 and abuts against one end of the ejector rod 702, the feeding servo motor 1006 stops working. At this time, drive the second semi-circular track 303 to descend by the clamping cylinder 312, so that the second semi-circular track 303 fits on the upper side of the first semi-circular track 302, and the two semi-circular sliding rings 304 inside the second semi-circular track 303 and the first semi-circular track 302 fit to form a complete smooth ring. At the same time, a plurality of mounting posts 305 and balls 306 inside the two semi-circular sliding rings 304 clamp the steel pipe. Then, drive the driving gear 308 to rotate by the rotating servo motor 309, drive the semi-circular gear ring 307 to slide inside the first semi-circular track 302, so that the two semi-circular sliding rings 304 rotate inside the first semi-circular track 302 and the second semi-circular track 303, and then drive the steel pipe to rotate. Then, drive the connecting plate 411 to rotate by the adjusting cylinder 412, which can drive the rotating cylinder 408 to rotate around the fixed shaft 409, drive the fixed bracket 401 on the other side of the rotating cylinder 408 to rotate, and then drive the saw blade 406 on the fixed bracket 401 to rotate around the fixed shaft 409, so that the saw blade 401 rotates and cuts on the outside of the steel pipe. And during the rotary cutting process, drive the slide plate 5 to slide by the electric telescopic rod 6, so that the fixed pipe 801 in the middle of the slide plate 5 is inserted into the inside of the steel pipe, and then the grinding head 804 at one end of the fixed pipe 801 is inserted into the inside of the steel pipe, so that the grinding head 804 gradually moves from the initial end of the steel pipe to one side of the cutting surface. During the cutting process, the cleaning water can be pumped into the inside of the water inlet pipe 802 by the water pump, and then enter the inside of the fixed pipe 801, so that the cleaning water is ejected from a plurality of spray heads 803 at one end of the fixed pipe 801, so that during the cutting of the steel pipe, the inside of the steel pipe is cooled, and during the cutting-off process, the saw blade 406 can also be cooled, improving the service life of the saw blade 406. When the steel pipe is completely cut off, the electric telescopic rod 6 continues to drive the slide plate 5 to move to one side of the steel pipe, so that the grinding head 804 at one end of the fixed pipe 801 moves to the position of the cutting surface.The burrs on the inner wall of the cutting surface can be polished by the friction between the rotating steel pipe and the grinding head 804. Moreover, the electric telescopic rod 6 continues to drive the sliding plate 5 to slide horizontally, and the grinding head 804 at one end of the fixed pipe 801 can also slide horizontally on the inner wall of the steel pipe to polish the rust on the inner wall of the steel pipe, which is convenient for subsequent use. After the polishing is completed, the clamping cylinder 312 drives the second semi-circular track 303 to rise, and the cut steel pipe section can fall into the inner side of the blanking port 9 under the action of gravity, so that the cut steel pipe section is collected in the collection box below the blanking port 9.
