Since the two ends of the pressing plate 104 are in the oblique grooves of the slide plate 103, the downward movement of the pressing plate 104 will cause the slide plates 103 on both sides to move toward the middle, thereby limiting the greenhouse steel pipe 102 for convenient cutting;

[0039] In an optional embodiment of the present invention, Figure 8-Figure 14The cleaning components include a cleaning support plate 305, a push frame 306, a cleaning drum 307, an electric cylinder 2 308, a motor 309, a round table rod 310 and a cleaning brush 311; the cleaning support plates 305 on the three cleaning components are respectively slidably installed in two square sleeves 302 and a T-shaped plate 301, a built-in electric cylinder is provided between the T-shaped plate 301 and the corresponding cleaning support plate 305, and a built-in electric cylinder is provided between the square sleeve 302 and the corresponding cleaning support plate 305. The middle part of the push frame 306 is slidably installed in the square groove of the cleaning support plate 305, and one end of the push frame 306 The second electric cylinder 308 and the third motor 309 are fixedly mounted on one side of the cleaning support plate 305. The motor shaft of the third motor 309 is provided with a cylindrical gear. One end of the cleaning drum 307 is rotatably mounted on the cleaning support plate 305. The cleaning drum 307 is provided with a gear ring. The gear ring on the cleaning drum 307 is meshed with the cylindrical gear on the motor shaft of the third motor 309. The truncated cone rod 310 is slidably mounted inside the cleaning drum 307. The cleaning brush 311 is slidably mounted on the ring of the truncated cone rod 310 through the round rod. The truncated cone part of the truncated cone rod 310 contacts the round rod of the cleaning brush 311, and a spring is provided on the round rod of the cleaning brush 311, and the spring on the cleaning brush 311 is fixedly connected to the outside of the circular ring on the truncated cone rod 310; when the cleaning assembly enters the interior of the greenhouse steel pipe 102, the telescopic rod of the electric cylinder 2 308 extends, and the pushing frame 306 drives the truncated cone rod 310 to move toward the side close to the greenhouse steel pipe 102, and the truncated cone part of the truncated cone rod 310 pushes the cleaning brush 311 outward, so that the cleaning brush 311 contacts the inner wall of the greenhouse steel pipe 102, and then the motor 309 works, and the motor The three 309 drives the cylindrical gear on the motor three 309, thereby driving the gear ring on the cleaning drum 307. The rotation of the cleaning drum 307 drives the cleaning brush 311 to rotate, and cleans the inner wall of the greenhouse steel pipe 102. Then, while the cleaning brush 311 rotates, the motor two 304 works, and the motor two 304 drives the screw 303 to rotate, driving the T-shaped plate 301 to move away from the greenhouse steel pipe 102. The T-shaped plate 301 drives the square sleeve 302 and the three cleaning components to move outside the greenhouse steel pipe 102, and cleans the debris out of the greenhouse steel pipe 102.

[0040] Working principle: When using this equipment, adjust the spacing of the three cleaning components according to the specifications of the steel pipe 102 for the greenhouse. First, manually unplug the retaining bolt on the adjusting screw 312, turn the knob to drive the adjusting screw 312 to rotate on the T-shaped plate 301. Since symmetrical threads are arranged at both ends of the adjusting screw 312, the rotation of the adjusting screw 312 drives the square sleeves 302 on both sides to move outward or inward at the same time. When the appropriate spacing is adjusted, insert the retaining bolt on the adjusting screw 312 into the circular hole of the knob on the adjusting screw 312 and the circular hole of the cross bar at the lower end of the T-shaped plate 301, and clamp the adjusting screw 312 on the T-shaped plate 301, so that the adjusting screw 312 no longer rotates;

[0041] After the greenhouse steel pipe 102 is fed onto the support frame 101, the motor on the rotating shaft of the feed roller 106 drives the feed roller 106 to rotate, and the rotation of the feed roller 106 drives other feed rollers 106 to rotate through the sprocket and chain. Since the feed roller 106 is in contact with the greenhouse steel pipe 102, the feed roller 106 drives the greenhouse steel pipe 102 to move, thereby completing the feeding function of the greenhouse steel pipe 102;

[0042] The telescopic rod of the electric cylinder 105 is extended to move the pressing plate 104 downward. Since the two ends of the pressing plate 104 are in the inclined slide grooves of the slide groove plate 103, the downward movement of the pressing plate 104 will cause the slide groove plates 103 on both sides to move toward the middle, thereby limiting the position of the greenhouse steel pipe 102, which is convenient for cutting;

Thus, the greenhouse steel pipe 102 is cut; when the motor 202 continues to rotate, the centrifugal cylinder on the turntable 201 drives the T-shaped rod 203 to move upward in the slide groove rod of the support frame 101, and the T-shaped rod 203 drives one end of the rotating rod 204 to move upward in the vertical slide groove of the support frame 101, and the other end of the rotating rod 204 drives the support rod 205 to rotate around the rotating shaft of the support rod 205, and the circular saw blade 206 on the support rod 205 moves away from the greenhouse steel pipe 102, and resets to facilitate the next cutting;

[0044] The built-in electric cylinder installed on the cleaning support plate 305 drives the cleaning component to rise, so that the cleaning component is aligned with the inside of the greenhouse steel pipe 102, and then the motor 2 304 drives the screw 303 to rotate, and the screw 303 drives the T-shaped plate 301 to move in the slide groove of the support frame 101 to the square close to the greenhouse steel pipe 102, and the cleaning component is sent into the greenhouse steel pipe 102; the telescopic rod of the electric cylinder 2 308 is extended, and the push frame 306 drives the round table rod 310 to move to the side close to the greenhouse steel pipe 102, and the round table part of the round table rod 310 pushes the cleaning brush 311 outward, so that the cleaning brush 311 and the greenhouse steel pipe 102 are aligned. The inner wall contacts, and then motor three 309 works, motor three 309 drives the cylindrical gear on motor three 309, thereby driving the gear ring on the cleaning drum 307, and the cleaning drum 307 rotates to drive the cleaning brush 311 to rotate, and the inner wall of the greenhouse steel pipe 102 is cleaned, and then while the cleaning brush 311 rotates, motor two 304 works, motor two 304 drives the screw 303 to rotate, and drives the T-shaped plate 301 to move away from the greenhouse steel pipe 102, and the T-shaped plate 301 drives the square sleeve 302 and the three cleaning components to move outside the greenhouse steel pipe 102, and cleans the debris out of the greenhouse steel pipe 102.
