Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to an agricultural fertilization UAV. Background Art

[0002] Agricultural fertilization drones refer to unmanned aerial vehicles equipped with fertilization equipment and related sensors. They can perform precise fertilization operations over farmland through remote control or autonomous flight. They can be used for fertilization operations on various farmlands, including paddy fields, dry fields, etc. Fertilization through drones can reduce manpower and machinery costs and improve agricultural production efficiency.

[0003] When agricultural fertilizing drones are performing fertilizing work, the fertilizer liquid is stored in the medicine box. Since the liquid contains solid particles or solutes of different densities and particle sizes, these particles or solutes may settle due to gravity during long-term standing or transportation. The precipitation of the liquid medicine will cause uneven concentration of the liquid medicine in the medicine box, thereby affecting the uniformity of spraying. In addition, the precipitation of the liquid medicine will clog the nozzle, resulting in reduced spraying efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the liquid medicine in the medicine box of the existing fertilizer drone is prone to precipitation. The precipitation of the liquid medicine will lead to uneven concentration of the liquid medicine in the medicine box, which in turn affects the uniformity of spraying. The precipitation of the liquid medicine will also clog the nozzle, resulting in reduced spraying efficiency. An agricultural fertilizer drone is proposed to solve the problem that the liquid medicine in the medicine box of the existing fertilizer drone is prone to precipitation.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figures 1-6 This embodiment provides an agricultural fertilizing drone, comprising a body 1, a medicine box 2 provided at the bottom of the body 1, a spraying mechanism 3 provided on the medicine box 2, landing gear 4 provided at both sides of the medicine box 2 at the bottom of the body 1, a filter 6 provided inside the medicine box 2 via an outlet pipe 5 connected thereto, and a stirring mechanism 7 provided on the medicine box 2 for preventing sedimentation and clogging of the medicine liquid therein;

[0025] The spraying mechanism 3 includes a liquid pump 31 arranged on the front side of the medicine box 2, and a mounting pipe 32 arranged at the bottom of the medicine box 2 through a connecting component 33. A nozzle 34 is provided at the bottom of the mounting pipe 32. The output end of the liquid pump 31 is connected to the mounting pipe 32 through a connecting pipe 35, and the input end of the liquid pump 31 is connected to the medicine box 2 through a liquid extraction pipe 36. The number of the nozzles 34 is at least two and they are evenly arranged on the mounting pipe 32 along its axial direction.

[0026] In the present invention, when agricultural fertilization is carried out, the body 1 flies above the farmland that needs to be fertilized, the liquid pump 31 on the medicine box 2 is started and the liquid medicine in the medicine box 2 is extracted through the liquid extraction pipe 36, and then sent into the installation pipe 32 at the bottom of the connecting component 33 through the connecting pipe 35. The liquid medicine entering the installation pipe 32 is sprayed out through a plurality of nozzles 34 at the bottom, thereby realizing the fertilization work. During the spraying process, the stirring mechanism 7 in the medicine box 2 is started to stir the liquid medicine in the medicine box 2 to mix it evenly and avoid precipitation, thereby ensuring that the pesticide and water or other solvent in the medicine box 2 are fully mixed to form a uniform spray liquid. During the stirring process, the filter screen 6 on the outlet pipe 5 can also be cleaned to prevent the filter screen 6 from being blocked, thereby maintaining the uniformity of spraying.

[0027] It should be noted that the connecting assembly 33 includes a connecting seat 331 and a clamping seat 332 that cooperate with each other to form a clamp structure. The connecting seat 331 and the clamping seat 332 are connected by a connecting bolt 333. The detachable design of the clamping seat 332 and the connecting seat 331 can facilitate the disassembly and assembly of the installation tube 32 at the bottom of the drone, thereby facilitating the maintenance and cleaning of the nozzle 34, ensuring that the nozzle 34 can effectively and evenly spray the liquid medicine.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the stirring mechanism 7 includes a motor 71 arranged on the rear side of the medicine box 2, and a connecting shaft 72 located inside the medicine box 2 is provided on the output end of the motor 71, and a stirring rod 73 is provided on the connecting shaft 72.

[0029] Among them, after the liquid medicine is stored inside the medicine box 2, the motor 71 drives the stirring rod 73 on the connecting shaft 72 to rotate, so that the stirring rod 73 stirs the liquid medicine in the medicine box 2. The fertilizer liquid is stored in the medicine box 2. Since the liquid medicine contains solid particles or solutes of different densities and particle sizes, these particles or solutes will settle due to gravity during long-term standing or transportation. Stirring is used to ensure that the pesticides and water or other solvents in the medicine box 2 are fully mixed to avoid the formation of precipitation, thereby forming a uniform spray liquid.

[0030] Specifically, such as Figure 2-Figure 4 As shown, the stirring mechanism 7 also includes a brush net assembly 74 arranged on the connecting shaft 72, and the brush net assembly 74 includes a positioning sleeve 741 sleeved on the connecting shaft 72, a connecting rod 742 is provided on the positioning sleeve 741, and the connecting rod 742 is provided with bristles 743 that contact the filter screen 6, a connecting screw sleeve 744 is provided on the positioning sleeve 741, and one end of the connecting rod 742 is provided with a threaded end 745 that cooperates with the connecting screw sleeve 744.

[0031] When the motor 71 drives the stirring rod 73 on the connecting shaft 72 to rotate so as to fully mix the liquid medicine in the medicine box 2, the connecting rod 742 installed on the connecting shaft 72 through the positioning sleeve 741 rotates accordingly, and the bristles 743 on the connecting rod 742 come into contact with the filter 6, so that the filter 6 can be cleaned by the bristles 743 when the connecting rod 742 rotates with the connecting shaft 72, and impurities and residual pesticides on the filter 6 can be removed in real time to prevent the filter 6 from being blocked, thereby maintaining the uniformity of spraying;

[0032] The connecting rod 742 is threadedly connected to the connecting screw sleeve 744 of the positioning sleeve 741 through the threaded end 745, so that the connecting rod 742 can be easily assembled and disassembled on the positioning sleeve 741, and the bristles 743 on the connecting rod 742 can be easily cleaned.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
