Description

Technical Field

[0001] The utility model relates to the technical field of farmland irrigation, in particular to a high-standard farmland irrigation and drainage dual-purpose device. Background Art

[0002] In the implementation of farmland water conservancy projects, the irrigation system and the drainage system need to operate in a coordinated manner. When the irrigation work is completed, the excess water will flow into the drainage channel to ensure that the amount of water in the farmland is maintained at an appropriate level. In order to achieve this goal, intermittent irrigation and drainage operations are required to avoid too much or too little water in the farmland. Especially in areas with high groundwater levels, the role of the drainage system is particularly important because it can effectively control the groundwater level and prevent damage to crops due to excessive water accumulation in the farmland.

[0003] Farm canals are an indispensable part of farmland water conservancy projects. They are responsible for diverting water from ditches to various fields. These farmland canals are key facilities to ensure smooth irrigation and drainage of farmland. They can help keep the water flow in the farmland at an appropriate level, thereby preventing the occurrence of too much or too little water. The existence of farmland canals enables farmland to be irrigated in a timely manner and drained effectively, ensuring that crops can grow in a suitable moisture environment.

[0004] However, in existing farmland water conservancy projects, irrigation channels and drainage channels are usually set separately. This design not only occupies a large amount of arable land, but also in actual use, the amount of water required for channel irrigation is large, resulting in relatively low irrigation efficiency. For this reason, we propose a high-standard farmland irrigation and drainage dual-purpose device. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in existing farmland water conservancy projects, irrigation channels and drainage channels are usually arranged separately, which not only occupies a large amount of cultivated land area, but also in actual use, the amount of water required for channel irrigation is large, resulting in relatively low irrigation efficiency. The utility model provides a high-standard farmland irrigation and drainage dual-purpose device.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A high-standard farmland irrigation and drainage dual-purpose device comprises a telescopic cylinder seat, a sliding piston is movably inserted into the upper end of the telescopic cylinder seat, and the upper end of the sliding piston is fixedly connected to an irrigation riser, a self-rotating irrigation nozzle is installed on the upper end of the irrigation riser, a water supply pipe is arranged at the bottom of the side wall of the telescopic cylinder seat, and a drainage pipe is arranged at the upper end of the side wall of the telescopic cylinder seat, and both the water supply pipe and the drainage pipe are connected to the inner cavity of the telescopic cylinder seat, a limit stop ring is fixedly connected to the upper end of the inner wall of the telescopic cylinder seat, and a compression spring is sleeved on the outer wall of the irrigation riser, the two ends of the compression spring are respectively abutted against the bottom of the limit stop ring and the upper end of the sliding piston, and the distance between the lower edge of the drainage pipe and the ground of the limit stop ring is equal to the length of the compression spring after compression.

[0008] Furthermore, a water collecting bucket is fixedly connected to the upper end of the telescopic cylinder seat, and the water collecting bucket is a conical bucket-shaped structure with the lower end facing downward.

[0009] Furthermore, a filter grille is plugged and fixed on the upper end of the water collecting bucket, and a mud retaining net is fixedly connected to the bottom of the filter grille. The filter grille is a porous plate grille, and the mud retaining net is a wire filter net.

[0010] Furthermore, the centers of the filter grille and the mud retaining net are fixedly connected with matching slip rings, and the matching slip rings are movably sleeved on the outer wall of the irrigation riser.

[0011] Furthermore, a cylindrical rib is provided at the upper end of the water collecting bucket, and a sedimentation trough is fixedly connected to the lower edge of the outer wall of the cylindrical rib of the water collecting bucket, and the upper edge of the sedimentation trough is flush with the ground in the low-lying part of the cultivated land.

[0015] 1. The multiple devices of the utility model are evenly distributed in the low-lying areas of the farmland, buried and installed through the telescopic cylinder seat, and high-pressure water is pumped out from the bottom through the water supply pipe. The water pressure in the telescopic cylinder seat pushes the sliding piston to move upward, and then sprays out from the self-rotating irrigation nozzle through the irrigation riser to achieve rotary spray irrigation. This process not only ensures the irrigation effect, but also saves irrigation water and improves irrigation efficiency. In addition, the accumulated water in the farmland can naturally gather at the upper end of the telescopic cylinder seat and be discharged through the drain pipe, realizing the integration of irrigation and drainage. This ensures the water management of agricultural farming without digging traditional irrigation and drainage channels, thereby significantly reducing the cultivated land area occupied by water conservancy projects.
