Description

Technical Field

[0001] The utility model belongs to the technical field of Venturi fertilizer applicators, and particularly relates to an adjustable fertilizer applicator. Background Art

[0002] A Venturi fertilizer applicator, also known as a Venturi fertilizer suction device, is a device that uses the vacuum suction generated when water flows through a specific pipe (Venturi tube) to uniformly suck a fertilizer solution from an open fertilizer bucket into the pipe system for fertilization. Its working principle is based on Bernoulli's principle, that is, when the water flow velocity increases, its static pressure energy will be converted into dynamic pressure energy, resulting in a local pressure reduction, forming a negative pressure area, so that the fertilizer solution can be sucked in.

[0003] However, the length of the existing adjustable fertilizer applicator is fixed and cannot be adjusted, so it cannot be applied to bypass pipes with different installation spacings, which is rather inconvenient. Summary of the Utility Model

[0011] Preferably, a second connector is threadedly sleeved on the liquid inlet pipe. A hose is provided on the second connector. An annular groove is provided on the sliding connection pipe, and a sealing rubber ring is provided on the annular groove.

[0012] Compared with the related art, the adjustable fertilizer applicator provided by the present utility model has the following beneficial effects:

[0013] Compared with the prior art, for the adjustable fertilizer applicator provided by this solution, the fertilizer applicator body composed of the conical tube, the throat and the fertilizer extraction mechanism can use the Venturi principle to direct the liquid fertilizer to the bypass pipeline. The sliding connection pipe is slidably installed on the inner wall of the conical tube, so that the length of the fertilizer applicator can be adjusted as needed, increasing the flexibility and applicability of the fertilizer applicator.

The first connector is provided on the sliding connection pipe for connecting to the bypass pipeline. The U-shaped plate is fixedly installed on the throat, serving as the installation basis of the length adjustment mechanism and also possibly providing additional structural support. The length adjustment mechanism is installed on the U-shaped plate. By adjusting the position of the sliding connection pipe in the conical tube, the length of the fertilizer applicator is adjusted. This adjustment function enables the fertilizer applicator to be applicable to bypass pipelines with different installation spacings. The fertilizer extraction mechanism is provided on the throat and uses the Venturi principle to direct the liquid fertilizer to the throat;
