Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the utility model is further described.

[0024] figure 1 Shown is an embodiment of the hydraulic drive piston type fertilization pump of the present invention, the housing 1 of this fertilization pump is equipped with a drive piston 2, figure 1 The diameter of the middle driving piston 2 decreases stepwise from the left end to the right end, forming a large end 15 , a middle end 16 and a small end 17 . Three chambers, A chamber 30 , B chamber 31 and C chamber 32 , are provided between the housing 1 and the large end 15 to the small end 17 of the driving piston 2 . In the cavity of the big end 15 of the driving piston 2, a reversing piston sleeve 5 is fixedly connected by tight fit, and there is no relative movement between the driving piston 2 and the reversing piston sleeve 5 . A reversing piston 6 is housed in the cavity of the reversing piston sleeve 5 . A movable sealing ring H4 is installed on the pi...

Abstract

A waterpower actuated piston type fertilizer application pump, wherein a piston is arranged in the outer casing, the inner chamber of the activation piston is provided with a reversing piston jacket for accommodating a reversing piston, the reversing piston rod is provided with a movable sealing ring. By using load water as the driving power, the activation piston and the reversing piston are pushed to reciprocate, thus opening the fertilizer suction pipe and injection pipe alternatively, and realizing fertilizer suction and fertilizer injection.

Description

technical field [0001] The invention relates to farmland irrigation equipment, in particular to a hydraulically driven piston type fertilization pump which fertilizes crops while irrigating them. Background technique [0002] With the widespread application of micro-irrigation technology in irrigation, a major revolution has taken place in fertilization technology. Soluble fertilizers are sent into the water distribution network in the form of solution through special equipment (and diluted by irrigation water in the pipe network). Fertilize crops while irrigating them. Therefore, fertilization equipment has become an indispensable component of the micro-irrigation system. [0003] The existing fertilization equipment used in the micro-irrigation system includes a fertilization tank, which is connected in parallel with the irrigation pipeline through branch pipes, and the fertilization tank is filled with fertilizer in solution state. When the irrigation water from upstrea...
