Description

Technical Field

[0001] The utility model relates to the technical field of agricultural fertilization, in particular to a liquid fertilizer fertilization device. Background Art

[0002] Liquid fertilizer has been gradually widely used as a new type of fertilizer. At present, there are several problems when applying liquid fertilizer in the field: First, most liquid fertilizers tend to sink to the bottom or stratify during the application process, resulting in uneven fertilizer concentrations before and after spraying; second, when applying liquid fertilizer in the field, large liquid fertilizer applicators are generally used. Due to the high application cost and wide rolling area, such large liquid fertilizer applicators are not suitable for fertilizing small and medium-sized farmers and grasslands; third, the traditional liquid fertilization method is not only inefficient and labor-intensive, but also difficult to accurately control the amount of fertilizer, resulting in fertilizer waste and environmental pollution.

[0003] Therefore, in view of the shortcomings of the prior art, the utility model proposes an innovative liquid fertilizer fertilizing device, which has the advantages of uniform stirring, low cost, labor and time saving, precise fertilization and portability. Utility Model Content

[0014] In this solution, the distribution plate diverts the liquid fertilizer flowing out of the discharge pipe, so that it is sprayed in a dispersed manner to the field through several spraying pipes, thereby increasing the fertilization range; the spraying motor drives the gear to rotate, and the gear drives the distribution plate to reciprocate at a certain angle through the rack, further increasing the spraying range of the spraying pipe and improving the fertilization efficiency.

[0015] Furthermore, a flow control valve and a self-priming pump are also provided on the discharge pipe; the flow control valve is arranged on a side close to the storage hopper, and the self-priming pump is arranged on a side close to the distribution plate.

[0016] In this solution, the self-priming pump provides pressure to transport the liquid fertilizer in the storage hopper to the distribution plate and spray it out from the spraying pipe, so that the fertilizer can be sprayed farther and over a wider range.

[0017] Furthermore, the discharge pipe between the self-priming pump and the material distribution tray is a stainless steel hose or a resin hose.
