Description

Technical Field

[0001] The utility model relates to the technical field of drone seeding, in particular to a drone combination device capable of seeding. Background Technique

[0002] With the adjustment of the national agricultural production structure and the development of agricultural modernization, the traditional farming mode has been difficult to meet the needs of modern agriculture. The traditional manual seeding method is not only time-consuming and laborious with low efficiency, but also easily restricted by natural conditions such as terrain and climate. The drone seeding technology has emerged. By carrying various agricultural operation devices such as seeders and sprayers, drones can achieve precise operations, providing new solutions for agricultural production.

[0003] At present, the existing drone seeding equipment generally adopts the structural method of assembling a seeding box at the bottom of the drone body. However, it is not difficult to find that the traditional seeding box structure is generally rectangular or cylindrical, with a large wind resistance during the drone carrying process. Coupled with the load of the seeding box, the energy consumption of the drone remains high, directly resulting in a shortened endurance of the drone and the need for frequent round-trip charging, affecting the smooth progress of agricultural seeding. Therefore, this application proposes a drone combination device capable of seeding. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drone combination device capable of seeding, which has smooth seeding, and has the advantages of low wind resistance and low energy consumption, improving the flight range of the drone body carrying the seeding box for seeding.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A drone combination device capable of seeding includes a drone body. A seeding box for seeding is suspended at the bottom of the drone body, and a landing gear is assembled at the bottom of the seeding box; the seeding box is set as a long strip structure, and both ends of the seeding box are in a conical shape; wing plates are arranged on both side walls of the seeding box, and the wing plates are distributed with a gradually downward inclination from the advancing direction of the drone body towards the other end.

[0007] Preferably, the drone body includes a drone fuselage, a plurality of wings arranged around the drone fuselage, and propellers installed on the wings. A plurality of suspension rods for suspending and installing the seeding box are vertically fixed at the bottom of the drone fuselage, and the drone fuselage and the plurality of wings are connected as a whole and are in a streamline shape.

[0008] Preferably, the landing gear includes two pairs of mounting plates fixed at the bottom of the seeding box and two foot rods horizontally installed at the bottom ends of the two pairs of mounting plates respectively. Rubber sleeves are sleeved at both ends of the foot rods, and a pull plate is connected between the two pairs of mounting plates.

[0009] Preferably, a camera is installed at one end of the seeding box facing the flight direction of the unmanned aerial vehicle body.

[0010] Preferably, a seeding pipe for discharging seeds for seeding is arranged at the bottom of the seeding box, and a stirring member for stirring seeds is arranged on the seeding box.

[0011] Preferably, the bottom of the seeding box is convex downward in an arc shape, a feeding port is arranged at the top of the seeding box, and a sealing cover is arranged on the feeding port.

[0012] Preferably, the stirring member includes a shaft rod rotatably installed in the seeding box, stirring blades arranged at the bottom end of the shaft rod, and a motor installed at the top of the seeding box for driving the shaft rod to rotate. The bottom end of the shaft rod extends towards the seeding pipe and is connected with a spiral conveyor shaft extending into the seeding pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] With the setting of the stirring member in the present utility model, after seeds are loaded into the seeding box and the unmanned aerial vehicle body takes off with the seeding box suspended, the motor is started to drive the shaft rod and the stirring blades to rotate. By using the rotation of the stirring blades, the seeds in the seeding box are stirred, which can improve the fluidity of the seeds in the seeding box, enabling the seeds to roll smoothly into the seeding pipe and be spirally conveyed and scattered under the cooperation of the spiral conveyor shaft following the rotation of the shaft rod, achieving the purpose of seeding with an unmanned aerial vehicle, ensuring the smoothness of the seeding process. And after the motor stops starting, the shaft rod and the spiral conveyor shaft stop rotating, and the seeds in the seeding box are blocked by the spiral conveyor shaft in the seeding pipe, so that seeding can be stopped, which is beneficial to realizing the fixed-point throwing seeding of the unmanned aerial vehicle. During the seeding process, ground video information can be obtained by using the camera, which is convenient for controlling seeding.

[0015] In the present utility model, the seeding box is suspended at the bottom of the unmanned aerial vehicle body through a suspension rod, so that there is a certain gap between the seeding box and the bottom of the unmanned aerial vehicle body, which is beneficial to the heat dissipation at the bottom of the unmanned aerial vehicle body during the load-bearing flight of the unmanned aerial vehicle. In addition, by setting the seeding box as a long strip structure and the two ends of the seeding box being in a conical shape, the wind resistance during the flight seeding of the unmanned aerial vehicle body with the seeding box suspended can be greatly reduced. By arranging wing plates on both side walls of the seeding box and the wing plates being gradually inclined downward from the advancing direction of the unmanned aerial vehicle body towards the other end, during the flight seeding of the unmanned aerial vehicle body with the seeding box suspended, a certain lift force can be provided, thereby reducing the power consumption of the unmanned aerial vehicle and increasing the flight range of the unmanned aerial vehicle body with the seeding box suspended for seeding.

[0016] Of course, it is not necessarily required that any product implementing the present utility model simultaneously achieves all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

A sowing box 2 for sowing is suspended at the bottom of the drone body 1. A sowing pipe 18 for discharging materials and sowing is provided at the bottom of the sowing box 2. A stirring member 7 for stirring seeds is provided on the sowing box 2. The bottom of the sowing box 2 protrudes downward in an arc shape. A feeding port 8 is provided at the top of the sowing box 2, and a sealing cover is provided on the feeding port 8. The stirring member 7 includes a shaft rod 15 rotatably installed in the sowing box 2, a stirring blade 17 provided at the bottom end of the shaft rod 15, and a motor 16 installed at the top of the sowing box 2 for driving the shaft rod 15 to rotate. The bottom end of the shaft rod 15 extends towards the sowing pipe 18 and is connected with a spiral conveyor shaft 19 extending into the sowing pipe 18. Seeds are loaded into the sowing box 2 from the feeding port 8. After the drone body 1 hangs the sowing box 2 and takes off, the motor 16 is started to drive the shaft rod 15 and the stirring blade 17 to rotate. The rotation of the stirring blade 17 is used to stir the seeds in the sowing box 2, which can improve the fluidity of the seeds in the sowing box 2, prevent the seeds from clogging, and make the seeds roll smoothly into the sowing pipe 18. In addition, under the rotation cooperation of the spiral conveyor shaft 19 following the shaft rod 15, the seeds are spirally conveyed and scattered by the sowing pipe 18, achieving the purpose of sowing by using a drone. After the motor 16 stops starting, the shaft rod 15 and the spiral conveyor shaft 19 stop rotating, and the seeds in the sowing box 2 are blocked by the spiral conveyor shaft 19 in the sowing pipe 18, and sowing can be stopped.

[0027] In this embodiment, a camera 9 is installed at one end of the sowing box 2 facing the flight direction of the drone body 1. During the flight and sowing process of the drone body 1 hanging the sowing box 2, ground video information can be obtained to facilitate sowing control.

[0028] In this embodiment, landing gears 3 are assembled at the bottom of the sowing box 2. The landing gears 3 include two pairs of mounting plates 11 fixed to the bottom of the sowing box 2 and two foot rods 12 horizontally installed at the bottom ends of the two pairs of mounting plates 11 respectively. Rubber sleeves 13 are sleeved at both ends of the foot rods 12, and a pull plate 14 is connected between the two pairs of mounting plates 11 for the landing of this drone.

[0029] As a preferred implementation manner of this embodiment, the drone body 1 includes a drone fuselage 4, a plurality of wings 5 arranged around the drone fuselage 4, and propellers 6 installed on the wings 5. A plurality of suspension rods 20 for suspending and installing the sowing box 2 are vertically fixed at the bottom of the drone fuselage 4. The drone fuselage 4 and the plurality of wings 5 are connected as a whole and are in a streamline shape, which can reduce wind resistance and energy consumption.

[0030] As a preferred implementation manner of this embodiment, the sowing box 2 is arranged in a long strip structure, and both ends of the sowing box 2 are in a conical shape; the air resistance during the flight sowing process of the unmanned aerial vehicle body 1 carrying the sowing box 2 is greatly reduced. Wing plates 10 are arranged on both side walls of the sowing box 2, and the wing plates 10 are gradually inclined downward from the advancing direction of the unmanned aerial vehicle body 1 towards the other end. During the flight sowing process of the unmanned aerial vehicle body 1 carrying the sowing box 2, a certain lift force can be provided, thereby reducing the power consumption of the unmanned aerial vehicle body 1.

[0031] During use, seeds are loaded into the sowing box 2. After the unmanned aerial vehicle body 1 carries the sowing box 2 and takes off, the motor 16 is started to drive the shaft rod 15 and the stirring blades 17 to rotate. By using the rotation of the stirring blades 17, the seeds in the sowing box 2 are stirred, improving the fluidity of the seeds in the sowing box 2, so that the seeds smoothly roll into the sowing pipe 18. Under the rotation cooperation of the spiral conveying shaft 19 following the shaft rod 15, the seeds are spirally conveyed and scattered from the sowing pipe 18, achieving the purpose of sowing by using the unmanned aerial vehicle, and the sowing process is smooth. At the same time, after the motor 16 stops starting, the shaft rod 15 and the spiral conveying shaft 19 stop rotating, and the seeds in the sowing box 2 are blocked by the spiral conveying shaft 19 in the sowing pipe 18, so that sowing can be stopped, which is beneficial to realizing the fixed-point scattering sowing of the unmanned aerial vehicle. During the sowing process, the ground video information can be obtained by using the camera 9, which is convenient for controlling sowing. Further, since the sowing box 2 is suspended at the bottom of the unmanned aerial vehicle body 1 by the suspension rod 20, there is a certain gap between the sowing box 2 and the bottom of the unmanned aerial vehicle body 1, which is beneficial to the heat dissipation at the bottom of the unmanned aerial vehicle body 1 during the load-bearing flight of the unmanned aerial vehicle body 1. In addition, by arranging the sowing box 2 in a long strip structure and both ends of the sowing box 2 being in a conical shape, the air resistance during the flight sowing process of the unmanned aerial vehicle body 1 carrying the sowing box 2 can be greatly reduced. By arranging the wing plates 10 on both side walls of the sowing box 2 and the wing plates 10 being gradually inclined downward from the advancing direction of the unmanned aerial vehicle body 1 towards the other end, a certain lift force can be provided during the flight sowing process of the unmanned aerial vehicle body 1 carrying the sowing box 2, thereby reducing the power consumption of the unmanned aerial vehicle body 1 and increasing the flight range of the unmanned aerial vehicle body 1 carrying the sowing box 2 for sowing.
