Description

Hanging fertilizer applicator Technical field

The invention relates to a fertilizer applicator, in particular to a fertilizer applicator for applying liquid fertilizer to fruit trees.

Background technique

In the garden industry and fruit trees and other crops, in order to make the forest grow stronger, it is necessary to carry out loosening and fertilization frequently. In the traditional technology, the laborer uses the manual deep-type loose soil fertilizing machine to realize deep loose soil, but it can only be applied to soft soil, the pressing depth is shallow, the efficiency is low, the fertilizer amount cannot be quantified, and the machine is heavy and difficult to operate. Workers work hard.

In order to solve the problems existing in the traditional manual processing method, in the prior art, the Chinese invention patent whose patent name is a deep loose soil fertilizing machine is announced, the application number is 02272845.7, the application date is 2002.08.27, and the authorization announcement date is 2003. On September 3, the authorization announcement date is CN 2569541 Y. The structure is specifically including a main engine capable of generating shock vibration. The lower part of the main unit is connected with a loose soil rod that can be inserted into the soil to loosen the soil. The main unit is also connected with a loose soil rod. A storage tank for storing chemical fertilizers or pesticides, the bottom of the storage tank is connected to the inner cavity of the loose soil rod through a pipeline, and the main body is a pneumatic vibration machine. When the fertilizer application machine is working, the pneumatic vibration machine is opened, and the pneumatic vibration machine is used for loosening the soil. The force of the downward impact of the rod can be deepened to a predetermined depth without manual pressing. The liquid fertilizer, solid fertilizer or powdered fertilizer in the storage tank enters the loose soil rod from the storage tank, and the main machine is an impact machine. Suitable for soils with a certain degree of hardness or knot, but this structure is only loosened by impact machinery. The soil around the lower end of the loose soil rod is still tight and the soil is impervious. At this time, when the fertilizer is directly applied to the soil along the discharge port of the loose soil rod, it is difficult to uniformly apply the fertilizer to the roots of the plant, which is not conducive to the growth of the plant roots; in addition, when the walkable area around the trees Very little, the fertilizer machine could not fertilize the trees around the trees, which made the fertilization work impossible.

When the depth of the earth-boring device into the soil reaches the requirement, the wind and the wind are closed. The lifting drive, the wind is no longer vibrating, and the lifting rod is no longer lowered. At this time, compressed air is introduced into the gas-liquid connection passage, and compressed air having a certain impact force flows from the exhaust liquid hole along the inner chamber of the excitation rod. Break into the soil, loosen the original tight soil around the earthenware, increase the soil permeability, facilitate the application of fertilizer to the soil, increase the effective area of the fertilizer and soil contact; then, enter the liquid into the gas-liquid connection channel The fertilizer and the liquid medicine are applied to the loosened soil from the exhaust liquid supply hole along the inner cavity of the excitation rod, and the effective area of the fertilizer and the soil is large, which is beneficial to the growth of the plant root system; the invention The exhibition mechanism drives the fertilization mechanism to extend outward, so that the fertilization mechanism surrounds the fruit tree to be fertilized, and the fertilization machine can be moved to the fruit tree to realize the fertilization work of the fruit tree.
