AI Technical Summary
The existing microspray belts have problems such as limited laying length, large pressure loss and insufficient spray uniformity in wheat-corn annual rings, which are difficult to meet the needs of long-distance irrigation, especially in the dual use of wheat-corn annual rings.
A wheat-corn annual ring-acting micro spray belt was designed. The belt length was 100m and the pipe diameter was 40-50mm. The spray holes were distributed at oblique intervals on the upper side of the belt, each of which was a group of 5 holes, with a spacing of 95-140mm, and the spray hole diameter was 1/100 of the pipe diameter of the belt. The distance and angle settings between the spray holes were optimized to achieve uniform spraying from a long distance.
It achieves low pressure loss (no more than 20%) and high spray uniformity at 100m laying length, which is suitable for wheat-corn annual rotation, reduces mechanized operation costs, and achieves efficient utilization and conservation of irrigation resources.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of micro spray belts, in particular to a dual-purpose micro spray belt for annual rotation of wheat and corn. Background Technique
[0002] As an irrigation device that is easy to use and has low requirements for water quality, the micro spray belt combines the advantages of traditional sprinkler irrigation and micro irrigation and has become one of the main methods of micro irrigation technology. Compared with surface irrigation, the micro spray belt can reduce the water consumption of crops by 10% - 40% and increase the yield and water use efficiency by 15% - 20%. Due to its low working pressure, strong adaptability to plots, low price, simple installation, and mature supporting equipment, the micro spray belt has been widely used in the rotation planting of winter wheat and summer corn in North China, which can not only achieve precise irrigation but also facilitate the integration of water and fertilizer.
[0003] However, the working pressure of the currently used micro spray belt is generally 60 - 100 kPa, and under this pressure condition, the spraying uniformity at the head and tail can only be achieved within a laying length of 50 - 70 meters. Therefore, the laying length in the field generally can only reach 50 - 70 meters, which leads to more branch pipes laid in the field, affecting mechanized operations and increasing labor costs. In addition, there is a lack of a dual-purpose micro spray belt suitable for the annual rotation of wheat and corn. Therefore, there is an urgent need to provide a special micro spray belt product suitable for the annual rotation of wheat and corn, which can achieve long-distance laying and high irrigation uniformity. Content of the Utility Model

[0007] The laying length of the belt body is 100 m, and the pipe diameter is 40 - 50 mm;
[0008] The spray holes are arranged on the upper side surface of the micro spray belt body after being flattened.

[0012] As an embodiment of the present utility model, after the wheat-corn rotation annual dual-purpose micro-spray belt is filled with water, when the working pressure is 60-100 kPa, the single-side spray width at the head end is 1.5 m - 1.8 m, and the single-side spray width at the tail end is 1.2 - 1.5 m; and the difference between the single-side spray width at the head end and the single-side spray width at the tail end is less than 0.5 m.

[0016] The beneficial effects produced by adopting the above technical solutions are as follows:
[0017] The wheat-corn rotation annual dual-purpose micro-spray belt provided by the present utility model sets the number of spray holes, the hole spacing of each group of holes, the horizontal distance and vertical distance between any two spray holes, and the distance between the spray hole close to the side edge and the side edge according to the different pipe diameters of the belt body, so as to ensure that the laying length can reach 100 m, the working pressure is 60-100 kPa, and the inlet flow rate is 3-10 m 3 / h, and the pressure loss ratio is not higher than 20%; the spraying uniformity is good.

Through the matching of agricultural machinery and agronomy, when harvesting wheat, only the micro-spray belt branch pipes and connecting pipe fittings need to be removed, and the micro-spray belt remains stationary. After sowing corn and connecting the branch pipes, irrigation and integrated fertilization of water and fertilizer can be continued to achieve "dual use of one belt", maximizing the application of resources and saving costs.
