Description

Technical Field

[0001] The invention belongs to the technical field of agricultural planting, and particularly relates to a device for pepper fertilization and a pepper fertilization method. Background Art

[0002] With the rapid development of my country's economy and science and technology in recent years, the scientific and technological level has been significantly improved. Traditional manual fertilization has gradually been replaced by mechanical fertilization equipment, and compound fertilizer fertilization has been adopted for agricultural crops. Compound fertilizer is a chemical fertilizer containing two or more nutrients. Compound fertilizer has the advantages of high nutrient content, few side effects and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yields of crops.

[0003] Peppers are generally fertilized using horizontal fertilizer equipment, which can be automatically fertilized after being installed on agricultural machinery. However, fertilizer bins of existing horizontal fertilizer spreaders are mostly separately arranged, so when installed on agricultural machinery, usually only 1 to 2 fertilizer bins for fertilization can be installed. In large-scale pepper planting bases, ridges or furrows are mainly used, and the area is large. Ordinary horizontal fertilizer spreaders have low fertilization efficiency, and fertilizers are easy to clump in the fertilizer bin, which will affect the fertilization effect. Therefore, an improved device for pepper fertilization is designed and a pepper fertilization method is provided. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a device for pepper fertilization and a pepper fertilization method to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A device for fertilizing peppers, comprising a drone and a fertilizing device detachably connected to the drone, wherein the drone comprises a drone frame, drone wings connected to the drone frame, and a drone landing gear;

[0007] The fertilizing device comprises: a liquid storage tank, which is detachably suspended and connected to the bottom of the UAV frame; a spray rod, which is connected to the liquid storage tank and is connected to a plurality of nozzles.

[0008] Furthermore, a propeller is connected to the end of the drone wing, a battery, a flight controller and a sensor are arranged inside the drone frame, and the battery and the propeller are electrically connected to supply power to the propeller.

[0009] Furthermore, the UAV landing gear includes four struts, which are arranged in groups of two. The two groups of struts are respectively connected to two sides of the UAV frame. The liquid storage tank is located between the two groups of struts. The bottom of the struts is connected to a bottom rod, and a buffer sleeve is provided on the bottom rod.

[0010] Furthermore, a top cover is provided on the top of the liquid storage tank, a connecting column connected to the UAV frame is provided on the top cover, a connecting head connected to the spray rod is provided at the bottom of the liquid storage tank, a liquid inlet pipe is connected to the side wall of the liquid storage tank, liquid fertilizer is added to the liquid storage tank from the liquid inlet pipe, flows into the spray rod through the connecting head, and is sprayed out from the nozzle for fertilizer.

[0011] Furthermore, a stirring mechanism is provided inside the liquid storage tank to prevent fertilizer precipitation, and a filtering structure is movably provided inside the connector to prevent particles from clogging the nozzle.

[0012] Furthermore, the stirring mechanism includes: a stirring rod, which is rotatably connected to the center of the top cover, one end of the stirring rod is exposed outside the top cover, and the other end extends into the liquid storage tank, and a stirring blade is connected to a section of the stirring rod located in the liquid storage tank, and the top of the stirring rod is connected to the stirring blade, and the stirring blade is located between the top cover and the UAV frame.
