Description

Technical Field

[0001] The invention relates to the technical field of drip irrigation tape laying, and in particular to a shallow buried drip irrigation laying device and method. Background Art

[0002] Drip irrigation does not destroy the soil structure. The water, fertilizer, air and heat inside the soil are always kept in a good condition suitable for crop growth. The evaporation loss is small, no surface runoff is generated, and there is almost no deep leakage. It is a water-saving irrigation method. The existing drip irrigation tape laying mostly requires the traction of a tractor or agricultural equipment. When working in a small area in some hilly and mountainous areas, the operation is relatively limited. In addition, when the laying equipment moves forward during the laying process, the drip irrigation tape is pulled from the drip irrigation tape roller by the compression force at the end of the drip irrigation tape, which is easy to break the drip irrigation tape and may even cause the compressed drip irrigation tape end to fall off, affecting normal laying. When each row of laying is completed, the drip irrigation tape needs to be cut manually, which is labor-intensive and has low operating efficiency. Summary of the invention

A first wedge-shaped block 551 is fixedly connected to the telescopic end of the second tension spring rod 55. A seventh support plate 552 is fixedly connected to the top of the first wedge-shaped block 551. Symmetrically distributed first connecting columns 553 are fixedly provided on the top of the seventh support plate 552. The first connecting columns 553 are rotatably connected to the first connecting rod 515. The movement of the seventh support plate 552 drives the movement of the pressing plate 514.

[0044] Symmetrically arranged second rotating seats 52 are fixedly connected to the top of the vehicle body 1. A rotatable second guiding wheel 521 is provided inside the second rotating seat 52. The second guiding wheel 521 is located between the pressing plate 514 and the vehicle body 1. A first through groove 554 is formed in the first wedge-shaped block 551.

When the shearing knife 56 cuts off the drip irrigation tape, the third connecting column 517 also moves out of the second through groove 561 accordingly, and the shearing knife 56 returns to the unfolded state. After the pressing plate 514 moves away from the drip irrigation tape, the inclined surface at the bottom of the third connecting column 517 can slide into the second through groove 561 along the side wall of the shearing knife 56. After a section of drip irrigation tape is laid, the third connecting column 517 can drive the shearing knife 56 to rotate again to cut off the drip irrigation tape.

A ninth connecting rod 63 is fixedly connected to the top of the fifth connecting rod 142, and the upper end of the ninth connecting rod 63 is slidably connected to the first through groove 554.

[0048] A method for using a shallow-buried drip irrigation laying device includes the following steps:

[0049] During use, the operator slides the rotating shaft of the drip irrigation tape reel 3 into the first chute 22. The drip irrigation tape is pulled out from the drip irrigation tape reel 3, passes through the space between the first guide roller 42 and the second guide roller 43, and then slides along the first guide wheel 512, the second guide wheel 521, the third guide wheel 532, and the fourth guide wheel 541. The hydraulic rod 54 is activated, and the telescopic rod of the hydraulic rod 54 extends. The ditching shovel 15, the fourth guide wheel 541, the earth-pushing plate 161, and the soil-pressing wheel 171 move downward synchronously, driving the drip irrigation tape to move downward accordingly.

[0050] The motor 41 is started, the handlebar 11 is pushed, and the vehicle body 1 moves forward. The ditching shovel 15 ditches the soil at the front end. The rotation of the motor 41 drives the rotation of the first guide roller 42, and the first gear 44 also rotates accordingly, driving the rotation of the second gear 45. The second guide roller 43 also rotates accordingly, driving the drip irrigation tape to be laid in the groove opened on the ground. The earth-pushing plate 161 and the soil-pressing wheel 171 assist in burying the drip irrigation tape in the soil. It can be used for small-area operations in hilly and mountainous areas, with a high degree of automation, saving time and effort.

[0051] When the drip irrigation tape is laid, the telescopic rod of the hydraulic rod 54 contracts, the fourth guide wheel 541 moves upward, driving the ninth connecting rod 63 to move upward. The upper end of the ninth connecting rod 63 slides along the first through groove 554, driving the first wedge block 551 to move towards the third support plate 4. The first connecting column 553 also moves towards the third support plate 4 accordingly, driving the rotation of the first connecting rod 515, and the pressing plate 514 also moves towards the drip irrigation tape. The pressing plate 514 clamps the drip irrigation tape, and the sixth connecting rod 143 also moves upward, driving the seventh connecting rod 621 to move upward. The rotating plate 6 rotates, driving the eighth connecting rod 611 to move downward, and the limiting plate 27 also moves downward to limit the rotating shaft of the drip irrigation tape reel 3.

[0052] At the same time, the movement of the pressing plate 514 drives the third tension spring rod 516 to move towards the second wedge block 522, and the shear knife 56 also moves towards the drip irrigation tape to cut the drip irrigation tape. The third tension spring rod 516 drives the third connecting column 517 and the third wedge block 523 to slide upward along the second wedge block 522. The upward movement of the third connecting column 517 squeezes the third tension spring rod 516. When the shear knife 56 cuts the drip irrigation tape, the third connecting column 517 also moves out of the second through groove 561, and the shear knife 56 returns to the unfolded state. After the pressing plate 514 moves away from the drip irrigation tape, the third connecting column 517 can be inserted into the second through groove 561 again, reducing the labor intensity and improving the work efficiency.

[0053] From the above description, it can be seen that in the above embodiments of the present invention, the slidable limiting plate 27 is provided to limit the rotation shaft of the drip irrigation tape reel 3, preventing the drip irrigation tape reel 3 from continuously rotating due to inertia. The rotatable cutting knife 56 is provided to automatically cut the drip irrigation tape, reducing the labor intensity and improving the work efficiency.

[0054] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
