Multifunctional sprayer

Abstract

The invention discloses a multifunctional sprayer which comprises a base and a water blending fertilizer box arranged on the base. The base is further provided with a high-pressure pump and a high-pressure water storage device, an outlet of the water blending fertilizer box is connected with an inlet of the high-pressure pump, an outlet of the high-pressure pump is connected with an inlet of the high-pressure water storage device through a high-pressure conveying pipe, and an outlet of the high-pressure water storage device is connected with an inlet end of a high-pressure main pipe. The high-pressure main pipe is sequentially provided with a high-pressure solenoid valve and a high-voltage pulse straight-line nozzle, wherein the high-pressure solenoid valve can control flow and pressure of single-hole liquid fertilizer pulse and is connected with a control switch, and the high-voltage pulse straight-line nozzle is arranged at the tail end of the high-pressure main pipe. The design philosophy of a deep fertilizer technology is adopted, particle fertilizer for topdressing is liquefied, is applied into a soil plowing layer (5-15cm) in a pulse straight line mode and is saved, working efficiency is high, and root systems of rice plants are not damaged.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multifunctional sprayer. Background technique [0002] Mechanized fertilization is an important part of the whole mechanization of rice production. Over the past 30 years of reform and opening up, rice production, one of the main food crops, has also made great progress and development, the main sign of which is the improvement of the degree of mechanization. Although the degree of mechanization of the whole process of rice production is increasing year by year, there is still a gap in the mechanization of the whole process in most areas. For example, when topdressing rice plants, farmers mostly adopt the method of spreading chemical fertilizers. This method of fertilization not only has a low utilization rate of chemical fertilizers, but also causes non-point source pollution. For this reason, people are committed to researching a mechanical deep fertilization device, su...

Although the degree of mechanization of the whole process of rice production is increasing year by year, there are still gaps in the mechanization of the whole process in most areas

For example, when topdressing rice plants, farmers mostly adopt the method of spreading chemical fertilizers. This method of fertilization not only has a low utilization rate of chemical fertilizers, but also causes non-point source pollution. For this reason, people are committed to researching a mechanical deep fertilization device, such as The Chinese invention patent with the publication number CN101884267A is a small rice liquid deep applicator, which uses a ditch knife to cut into the soil, and the fertilizer solution is applied to the depth of the field mud through the fertilizer delivery pipe and the fertilization channel, and then the fertilizer solution is sealed with the field mud in the mud

Although this design solves the waste caused by direct spreading of fertilizer, it will cut off the root system of rice and affect its growth when the ditch knife cuts into the soil

Another example is the Chinese utility model patent whose publication number is CN2322363Y, a kind of portable fertilizing and seeding gun. The root system of rice is damaged during fertilization, but the insertion nozzle repeatedly inserts and pulls out the field mud, which is difficult and inefficient, and cannot be popularized; in addition, the insertion nozzle is easily blocked and the work is not smooth

So far, the technology of deep application of rice chemical fertilizers has not been well solved
