Description

Technical Field

[0001] The invention relates to the field of agricultural production, and in particular to a drip irrigation pipe for agricultural planting. Background Art

[0002] Agriculture is an industry that uses the growth and development laws of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of agricultural labor are plants, animals and other organisms, and the products obtained come from the organisms themselves, such as silk and musk. Agriculture is a basic industry that provides support for the construction and development of the national economy.

[0003] Drip irrigation is an irrigation method that drips water and nutrients needed by crops into the soil in the root zone of crops evenly and slowly through a pipe system and an emitter installed on a capillary tube according to the water requirements of crops. Drip irrigation does not destroy the soil structure. The water, fertilizer, air and heat in 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.

[0004] The existing drip irrigation pipeline is achieved by setting up multiple main pipes in the field, connecting multiple sub-pipes to the main pipes, and then connecting several capillary tubes to the sub-pipes, so that the entire drip irrigation network is set up in the field, thereby achieving the drip irrigation effect. The sub-pipes and main pipes both use directly large pipes, while the capillary tubes use pipes with smaller diameters.

[0005] The gross tubes are recycled and reprocessed after use each year. Therefore, before the autumn harvest each year, the main tubes, sub-tubes and gross tubes need to be pulled out for recycling. However, the commonly used method is to pull them out manually, which is laborious and troublesome. On farmland with slightly flat terrain, a wheel is used to rotate, and a winding roller is fixed at the hub of the wheel. One end of the pipe is fixedly connected to the winding roller to form a simple winding device to realize the collection of the main tubes, sub-tubes and gross tubes, which is time-consuming, labor-intensive, and inconvenient to take.

[0006] Therefore, a drip irrigation pipeline that can be easily taken and installed is needed. Summary of the invention
