Compared with the prior art, the utility model has the following beneficial effects: an impeller is arranged in the first pipeline, and after fluid is introduced, the impeller is driven to rotate by utilizing fluid power, and the rotation of the impeller transmits the power to the fertilizer suction pump through a connecting shaft to provide power for the fertilizer suction pump; the flow direction of fluid can be changed by arranging the flow guide piece, so that the angle of the fluid passing through the flow guide piece impacting the impeller is changed, and the utilization rate of the impeller to fluid power is changed.
The above-mentioned changing of the flow direction of the fluid, changing of the angle at which the fluid impinges on the impeller, and changing of the utilization ratio of the fluid power by the impeller means that the flow direction of the fluid is changed as compared with the case where the flow guide is not provided. Under different use environments, a user can select a proper flow guide piece according to the use requirement, so that fluid can impact the impeller at different angles, and the impeller has different utilization rates of fluid power. For example, when a higher maximum fertilization amount is needed, the water flow direction can be changed through the flow guide piece, so that the water flow impacts the impeller blades at an angle close to the angle perpendicular to the impeller blades, and a higher water power utilization rate is obtained; when the fertilizer sucking amount is required to be smaller and stable, the water flow direction can be changed through the flow guide piece, so that the water flow can impact the impeller blades in a direction which is approximately parallel to the impeller blades, and the lower water power utilization rate is obtained.

The first opening of the first duct 1 is an opening in the side wall of the first duct 1, which communicates directly with a nozzle of the second duct 3. The second opening of the second pipeline 3 is another opening on the side wall of the first pipeline 1, and the second opening is communicated with the opening on the side wall of the second pipeline 3 through a connecting pipe 7. The other orifice of the second pipe 3 is used for discharging water.
The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; all other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
Claims (10)

The water power fertilizer applicator of claim 3, wherein the impeller central portion is bowl-shaped in shape, and the end of the bowl-shaped with smaller cross-sectional area is a flow-facing end, wherein the flow-facing end is the end of the impeller central portion which receives the impact of the fluid when the fluid passes through;
and/or the impeller is sleeved on the connecting shaft and is detachably connected with the connecting shaft.
6. The hydrodynamic fertilizer applicator of claim 3, wherein the guide center portion is sleeved with an outer connecting ring, one end of the guide vane is connected with the guide center portion, and the other end is connected with the outer connecting ring;
and/or the flow guiding central part is provided with a central hole for the connecting shaft to pass through.
7. The water powered fertilizer applicator of claim 6, wherein the first conduit inner wall is provided with a recess adapted to the outer collar.
8. The water powered fertilizer applicator of claim 1, wherein a plurality of impellers and deflectors are disposed within the first conduit, the deflectors alternating with the impellers.
9. The hydrodynamic fertilizer applicator of claim 1, wherein the two ends of the connecting shaft are connected with fertilizer sucking pumps;
and/or, the first pipeline comprises a pipe orifice, a first opening and a second opening, the fertilizer sucking pump is connected with the pipe orifice, the fertilizer sucking pump is connected with a fertilizer inlet pipe and a fertilizer outlet pipe, and the fertilizer inlet pipe, the fertilizer outlet pipe and the fertilizer sucking pump are not directly communicated with the first pipeline.
10. The hydro-dynamic fertilizer applicator of claim 1, further comprising a second conduit, wherein the first conduit communicates with the second conduit through a first opening, a second opening,
the first opening and the second opening are pipe orifices or side wall openings of the first pipeline, the impeller and the flow guide piece are positioned between the first opening and the second opening of the first pipeline, the first opening is positioned on the flow facing side of the impeller, and the flow facing side refers to the side of the impeller facing the fluid when the fluid passes through;
and/or, further comprising a regulating valve for regulating the water flux ratio in the first and second pipes.
