Description

Technical Field

[0001] The present invention relates to the technical field of installation equipment for irrigation products, and in particular to a steering gear-driven snap-fit ​​type irrigation pipe protective shell installation device and applications thereof. Background Art

[0002] Infiltration irrigation is a new water-saving irrigation method, a successor to sprinkler and drip irrigation. It boasts the highest utilization rate of all current irrigation technologies. Infiltration irrigation uses infiltration pipes to deliver irrigation water to a specific depth underground. This water is then infiltrated into the soil at regular intervals and in fixed quantities, depending on the crop's water requirements. Infiltration irrigation systems utilize piped water throughout the system, with irrigation water delivered directly to the crop roots. This keeps the ground and foliage dry, minimizing evaporation between crops. The soil moisture content in the planned wet layer is consistently below saturation, resulting in high water utilization.

[0003] The drawbacks of irrigation technology without protective casings are that the tiny drip holes in the pipes are easily clogged by soil and sediment, and microorganisms can easily grow in the drip holes in humid environments. Furthermore, plant roots can penetrate the capillaries of the pipes, blocking the drip holes. Over time, this damages the entire irrigation system, preventing it from properly supplying water to crops. To prevent this, a dripper is implanted inside the pipe. The diameter of the dripper is slightly larger than the pipe diameter. A labyrinthine groove is drilled inside the dripper, and drip holes are created in the pipe corresponding to the groove. A protective casing is then placed over the drip holes, nested inside the pipe, to divert the irrigation water secondary, transforming the water discharge pattern from the conventional point-shaped dripping pattern to a spiral loop. This structure effectively addresses the problem of clogging by sediment, microorganisms, and plant roots. However, current installation of protective casings on irrigation pipes is often done manually or semi-automatically. Existing irrigation pipes are long and have numerous drip holes, resulting in low efficiency and high costs. Summary of the Invention

[0039] The above-mentioned steering gear driven snap-fit ​​irrigation pipe protective shell installation device is mainly used for installing the protective shell on the irrigation pipe. The specific use process is as follows:

[0040] S1. First, the irrigation pipe without a protective shell installed passes through the rightmost guide wheel 205 in the guide assembly and enters from the right end of the hollow steel pipe 203, and extends from its left end outlet; at the same time, the translation cylinder 305 in the protective shell fastening mechanism 3 operates, and the piston rod extends, driving the fastening workbench 303 to slide along the guide rail 302 to the side of the hopper 41 and arrive at the loading station; the pushing cylinder 43 in the protective shell loading mechanism 4 operates, and the protective shells in the hopper 41 are pushed individually to the top of the fixed fastening mold 313 and the flip fastening mold 314 through the loading push plate 44; then the piston rod in the translation cylinder 305 is recovered, driving the fastening workbench 303 to move back to the fastening station, at which time the central axis of the fixed fastening mold 313 coincides with the central axis of the hollow steel pipe 203. The head end of the irrigation pipe is dragged by the above-mentioned irrigation pipe traction mechanism 5. When the dripper part on the irrigation pipe passes through the cut-off part at the left end of the hollow steel pipe 203, the diameter of the dripper part is larger than the diameter of the irrigation pipe, which lifts the roller 211 in the detection assembly located at the cut-off part. The lever 209 then swings, driving the tail end of the lever 209 to descend and block the photoelectric sensor 208. The photoelectric sensor 208 detects the action and records it. The initial end of the irrigation pipe passes through the protective shell fastening mechanism 3 and enters the irrigation pipe traction mechanism 5 to continue being pulled out.

[0041] S2. When the upper and lower dripper parts of the irrigation pipe pass the roller 211, the tail end of the lever 209 drops again to block the photoelectric sensor 208. At this time, the previous dripper part is just above the fixed fastening mold 313 in the protective shell fastening mechanism 3; then the servo 307 in the protective shell fastening mechanism 3 operates, driving the rotating shaft 312 to rotate through the coupling 309, thereby driving the reversible fastening mold 314 to rotate 180 degrees along the rotating shaft 312, covering the protective shell on the corresponding dripper part of the irrigation pipe, reaching a semi-fastened state.

[0042] S3: The dual-axis locking cylinder 317 in the protective shell locking mechanism 3 operates, its piston rod extending, driving the compression block 318 downward. This, in conjunction with the top of the punching pad 315, compresses and presses the outer edge of the protective shell, completing the installation of the protective shell. The servo 307 then reverses, driving the reversible locking die 314 to open. The servo motor 512 in the irrigation tube traction mechanism 5 operates, driving the two traction belts 504 to rotate synchronously via a gear transmission, thereby moving the irrigation tube with the protective shell installed forward and out.

[0043] S4. Repeat the above steps S1 to S3 to complete the installation of the protective shell on the entire irrigation pipe.
