Description

Technical Field

[0001] The utility model relates to a greening fertilization device, belonging to the field of gardening. Background Art

[0002] For the greening plants in the garden, it is necessary to fertilize them irregularly. A flexible infusion tube is installed at the liquid outlet end of the pump body to unfold the infusion tube. A plurality of hoses are installed on the infusion tube, and a liquid injection tube is installed at the other end of the hose. The liquid injection tube is inserted into the soil around the roots of the greening plants. When the pump body works, the water and fertilizer in the container are pumped through the infusion tube and the hose to the liquid injection tube, and then the water and fertilizer seep into the soil through the liquid outlet holes on the liquid injection tube, realizing the fertilization of the greening plants. With the continuous injection of water and fertilizer into the soil around the liquid injection tube, the soil around the liquid injection tube will become loose. At this time, the friction between the liquid injection tube and the soil decreases, and the water and fertilizer flowing in from the liquid outlet hole under the action of the pump body have a certain water pressure. Therefore, the liquid injection tube is easily pulled out under the action of the water pressure, so that the water and fertilizer flowing out from the liquid outlet hole are sprayed to the area far from the plant roots, resulting in the waste of water and fertilizer. Therefore, it is necessary to design a greening fertilization device to prevent the liquid injection tube from detaching from the soil. Content of the Utility Model

A vertically arranged positioning rod is fixedly connected to the other side of the upper surface of the rectangular tube away from the positioning screw. A water storage cylinder is arranged above the rectangular tube. A through hole is opened at the middle position of the inner bottom of the water storage cylinder. An insertion tube concentric with the through hole is arranged above the through hole. The lower end of the insertion tube is open and is fixedly connected to the water storage cylinder. The upper end of the insertion tube is closed. The positioning rod passes through the through hole and is inserted into the insertion tube.

[0005] Further, a support plate is fixedly connected to one end of the rectangular pipe away from the positioning screw. On one side of the upper surface of the support plate away from the rectangular pipe, a first threaded sleeve is installed. The first threaded sleeve penetrates through the support plate, and a support screw is threadedly connected inside the first threaded sleeve. A disc in contact with the ground is installed at the lower end of the support screw.

[0006] Further, a second threaded sleeve is installed on one side of the upper surface of the rectangular pipe close to the liquid injection pipe.
