Single lever hydraulic drive fertilization device

Abstract

The invention discloses a single-pole type hydraulic driving fertilizing device, which mainly comprises a driving cavity body, a main water inlet pipe, a first water inlet pipe, a second water inlet pipe, a first water outlet pipe, a second water outlet pipe, a main water outlet pipe, a moving piston, a control rod, and a fertilizer sucking mechanism; the moving piston is hydraulically driven to vertically and repeatedly move so as to drive the fertilizer sucking mechanism to work, thus the fertilizer sucking mechanism can absorb the fluid fertilizer; the fluid fertilizer is discharged to a main pipeline of an irrigation system through the main water outlet pipe to mix with the irrigation water, and then enters the field through the irrigation system, thereby reaching the purpose of water-fertilizer integrated fertilization. The hydraulic driving part and the fertilization ratio adjusting part are very simple in structure, and are not required to drive by additional power; the single-pole type hydraulic driving fertilizing device is easy to realize automation and free adjustment of fertilizer concentration; besides, the using scale is enlarged, and the labor intensity is reduced.

Description

Technical field [0001] The invention relates to agricultural machinery and equipment, in particular to a single-rod hydraulic drive fertilization device. Background technique [0002] Fertilization is a very important step in agricultural planting. The amount, uniformity of fertilization and the degree of coordination with irrigation directly determine the yield and quality of agricultural products. At present, my country's agricultural production is still dominated by traditional planting methods, and traditional methods such as hole application and spreading are still used for fertilization. The number of times of fertilization is small and the amount of single fertilization is large. Not only is fertilization uneven, but also easy to be leached by rainfall or irrigation water. , The efficiency of fertilizer utilization is very low, not only is it difficult to improve the yield and quality of agricultural products, but also the waste of fertilizer will increase the production co...

Problems solved by technology

Pump side-suction fertilization and injection pump require extra power, and the fertilizer will corrode the pump more. Pressure fertilization tank and Venturi fertilization increase energy consumption due to large pressure loss. These fertilization methods have the disadvantage that the fertilization ratio cannot be adjusted. , and the cost is high, the energy consumption is large, and the later use cost is high

The hydraulic-driven proportional fertilization pump has great application prospects because it uses pipeline water pressure to drive the fertilization pump, and can accurately adjust the fertilization ratio. The structure is quite complicated, there are many moving parts, and maintenance is difficult
