Background

In agricultural production, additional fertilization is needed during the growth of crops, and the traditional method is manual or mechanical spreading. With the rise and popularization of the drip irrigation water-saving technology, the form of a fertilizer product gradually develops from solid granular fertilizer to liquid fertilizer, so that the fertilizer is better suitable for a water-following fertilizer application technical mode. However, in some plots which do not have a drip irrigation system and are not suitable for flood irrigation, and plots which cannot be mechanically operated, such as mountainous plots, scattered plots in front of and behind houses, vegetable gardens, plots, greenhouses and the like, manual topdressing is still needed. However, the hole-opening fertilization method of manually applying the solid fertilizer cannot meet the operation requirement of applying the liquid fertilizer.

For example, although the manual opening and closing fertilizer applicator and the application method thereof disclosed in the chinese patent specification with the application number of 2015107976404 can realize quantitative manual hole fertilization, the process can only be adapted to solid granular fertilizer and cannot be adapted to the situation of applying liquid fertilizer, and the hand-held mechanism thereof is labor-consuming in soil penetration, large in hole opening resistance and poor in application effect. The device and equipment for manually and semi-manually applying the solid fertilizer similar to the patent are more common, but the equipment for manually or semi-manually applying the liquid fertilizer and pesticide is not available.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple and easy fertilizer injection unit that can smart volume control liquid measure and fix a position fertilization that liquid fertilizer medicine was executed to manual work.

Furthermore, the liquid tank, the piston cylinder and the liquid storage tank are all made of transparent materials.

By adopting the structural design, the liquid fertilizer or medicine filled into the liquid storage tank is stirred and then supplied to the liquid tank for buffering. When the piston is lifted upwards after the duckbill hollow conical head enters the soil, the liquid inlet is opened, the liquid outlet is closed, and the liquid enters the piston cylinder. The bolt type limit bolt determines the upward stop position of the piston, so that the quantification is realized and the adjustment is realized. When the manpower is removed, the piston moves downwards under the action of the central spring, the liquid inlet is closed, the liquid outlet is opened, and the liquid enters the duckbilled hollow cone head after being pushed out. The movable pull rod lifts the soft rope upwards to open the movable jaw, and the fertilizer liquid is discharged into soil. The handle is used for holding operation and can provide downward insertion force, and the depth limiting pedal not only can assist downward insertion by foot stepping, but also has the depth limiting function by being adjustable in height. The duckbilled hollow conical head in threaded connection is convenient to disassemble, repair and maintain. The device realizes manual handheld operation and has the functional characteristics of quantitative adjustability, fixed-point hole application, controllable depth and the like; the device has the advantages of exquisite structure, labor saving, convenience and flexibility, can be widely applied to manually applying liquid fertilizer and liquid pesticide to fruit tree seedlings, vegetables, sparsely planted crops and the like in small plots and small-scale planting, and can also be applied to water replenishing micro-irrigation in an expanded way.
