Double-rod hydraulic drive fertilization device

Abstract

The invention discloses a double-rod type hydraulic driving fertilization device. The double-rod type hydraulic driving fertilization device comprises a driving cavity, 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 motion piston, a first control rod, a second control rod and a fertilizer absorbing mechanism; and the motion piston is driven hydraulically to do up-and-down reciprocating motion, so that the fertilizer absorbing mechanism is driven to work, the fertilizer absorbing mechanism can absorb liquid fertilizer and the liquid fertilizer is discharged to the corresponding place through the main water outlet pipe. The double-rod type hydraulic driving fertilization device is simple in structure, does not need additional power driving, has high automation degree and reduces labor intensity.

Description

technical field [0001] The invention relates to agricultural machinery and equipment, in particular to a double-rod hydraulic drive fertilization device. Background technique [0002] Fertilization is a very important step in agricultural planting. The amount and uniformity of fertilization and the degree of cooperation 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 fertilization methods still use traditional methods such as hole application and spreading. The frequency of fertilization is small and the amount of single fertilization is large. Not only is the fertilization uneven, but it is also easy to be leached by rainfall or irrigation water. , The utilization efficiency of fertilizer is very low, not only it is difficult to improve the output and quality of agricultural products, but also the waste of fertilizer will increase the pr...

AI Technical Summary

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
