Abstract

The invention relates to a sprinkling irrigation machine capable of collecting rainwater for compensating irrigation, and belongs to the technical field of water-saving irrigation of agriculture. The sprinkling irrigation machine comprises a rainwater collecting tank, a main rod, sprinkling irrigation rods, compensation rods and a base, wherein the main rod is rotated into the base through a thread opening, universal wheels are arranged under the base, one side of the lower end of the main rod is provided with a water inlet, the upper end of the main rod is provided with an upper layer and a lower layer, the four sprinkling irrigation rods are arranged at the lower layer and are movably connected with the main rod, the four compensation rods are arranged at the upper layer and are movably connected with the main rod, the top end of the main rod is communicated with the rainwater collecting tank, a support groove of the rainwater collecting tank is formed in the lower part of the rainwater collecting tank and is fixedly connected with the main rod, the upper part of the rainwater collecting tank is communicated with a conical rainwater collecting groove, a filtering net cover is arranged at the upper part of the conical rainwater collecting groove, a sprinkling nozzle is arranged at the tail end of each sprinkling irrigation rod, three sprinkling nozzles are respectively arranged at the tail end of each compensation rod and are distributed in a triangle shape, and a sprinkling nozzle is arranged at one end near the main rod. The sprinkling irrigation machine has the advantages that the operation is simple, the weight is light, the cost is low, the design structure is simple and reasonable, the practicality is high, the storage and carrying are convenient, and the sprinkling irrigation machine is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to a sprinkler irrigation machine capable of collecting rain for compensation irrigation and belongs to the technical field of agricultural water-saving irrigation. Background technique [0002] Agricultural water-saving irrigation technology is a general term for irrigation methods, measures and systems that save water and use water more efficiently than traditional irrigation techniques. Through water-saving irrigation, crops can be irrigated in a timely manner, which improves the irrigation guarantee rate and can effectively promote the increase of crop production and income. Agricultural irrigation methods can generally be divided into three types: traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. However, traditional surface irrigation often consumes a lot of water and has low water use efficiency, which is a very unreasonable agricultural irrigation method. Compared with the traditional su...

AI Technical Summary

Problems solved by technology

[0003] Ordinary sprinkler irrigation technology has been widely used in agricultural production and landscaping irrigation, but there are still many scientific problems to be solved in sprinkler irrigation technology: first, the spraying uniformity is poor when multiple nozzles are used in combination

Under certain meteorological conditions, the uniformity of sprinkler irrigation water distribution on the field surface is mainly affected by four aspects: ①The working pressure of each sprinkler in the field is inconsistent due to the loss of pipeline water head and the terrain height difference, that is, the deviation of the working pressure of the sprinkler; The water volume of a single sprinkler caused by its own hydraulic performance is unevenly distributed on the surface; ③ Due to the difference in the spacing and combination of nozzles, the superimposition of the spraying water volume of two adjacent sprinklers is different, which will also affect the distribution of spraying water volume; ④ The terrain slope affects the water volume of a single sprinkler. The impact of distribution

Second, it is more affected by the wind

According to the sprinkler irrigation technical specification, if the wind speed exceeds level 3, it is not easy to use sprinkler irrigation technology. If the wind speed requirements are not strictly followed, the drift loss of spray droplets will be very serious during the spraying process, thereby reducing the water use efficiency.

Third, the operating cost of current sprinkler irrigation technology is relatively high

However, in this invention, the uniformity of spray irrigation is not mentioned, and water-saving devices such as rain collection are not installed, and two ways of rain collection and water injection cannot be realized for irrigation. The invention also does not provide for the treatment of impurities in irrigation water. corresponding plan
