Description

Technical Field

[0001] The present invention relates to the technical field of installation equipment for irrigation products, and in particular to a cylinder-driven snap-on 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

[0040] The above-mentioned cylinder-driven snap-on irrigation pipe protective shell installation device is mainly used for installing the protective shell on the irrigation pipe. Figure 6 and Figure 7 The specific usage process is as follows:

[0041] S1. First, the irrigation pipe without protective shell installed ( Figure 7 (as shown in a) in the middle, the protective shell enters from the right end of the hollow steel pipe 203 through the guide wheel 204 in the guide assembly and extends out from the outlet at the left end; at the same time, the conveying assembly in the protective shell feeding mechanism 3 is running, and the conveying belt 306 rotates in a step-by-step manner. The loading cylinder 309 in the loading assembly pushes the coded protective shells in the hopper 308 one by one to the two adjacent block positions on the conveying belt 306; the conveying motor 303 drives the protective shell to the loading position through the conveying belt 306. The irrigation pipe is dragged by the irrigation pipe traction mechanism 5. When the dripper portion on the irrigation pipe passes through the cut-off portion at the left end of the hollow steel pipe 203, the diameter of the dripper portion is larger than the diameter of the irrigation pipe, which lifts the roller 211 in the detection assembly at the cut-off portion. The lever 209 swings, driving the tail of the lever 209 to descend and block the photoelectric sensor 208. The photoelectric sensor 208 detects the movement and records it. The initial end of the irrigation pipe passes through the top of the conveyor belt 306 and the center of the protective shell fastening mechanism 4 and enters the irrigation pipe traction mechanism 5 to continue being pulled out.

[0042] S2. When the upper and lower dripper parts of the irrigation pipe pass the roller 211, the tail of the lever 209 drops again to block the photoelectric sensor 208. At this time, the previous dripper part is just above the left snap-fit mold 402 and the right snap-fit mold 403 in the protective shell snap-fit mechanism 4; then the pushing cylinder 62 in the protective shell pushing mechanism 6 runs, and the protective shell in the corresponding loading station on the conveyor belt 306 is pushed onto the left snap-fit mold 402 and the right snap-fit mold 403 through the pushing plate 63.

[0043] S3, then the power cylinder 405 in the protective shell fastening mechanism 4 is operated, and its piston rod is extended, driving the left fastening mold 402 and the right fastening mold 403 to rotate along the axis through the pull rod 404, driving the protective shell to close upward to a semi-fastened state (such as Figure 6 (As shown in b), the protective shell is wrapped around the dripper of the irrigation pipe; then the double-axis locking cylinders 410 in the two sets of locking cylinder assemblies operate synchronously, and the pressing blocks 411 thereon are pressed relative to each other to press the outer edge of the protective shell, completing the closing and installation of the protective shell. Then, each operating cylinder is reset, and the servo motor 506 in the irrigation pipe traction mechanism 5 operates, and through the transmission between the pulley and the gear, it drives the traction belts 514 on both sides to move synchronously, thereby clamping the irrigation pipe ( Figure 7 b) moves the output forward.

[0044] S4. Repeat the steps in S2 and S3 above to complete the installation of the protective shell on the entire irrigation pipe.
