Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

referring to fig. 1-2, an unmanned aerial vehicle for agricultural seeding, includes organism 1, and stock chest 2 has been seted up to the lateral wall of organism 1, and the communicating revolving chute 3 with stock chest 2 has been seted up to the lateral wall of organism 1, and revolving chute 3 internal seal sliding connection has a stirring wheel 4, and a plurality of feed inlets 5 have been seted up to the lateral wall of stirring wheel 4, and a plurality of feed inlets 5 along stirring wheel 4's circumference lateral wall equidistant distribution, and the bore of feed inlet 5 is less than the groove width of revolving chute 3. The side wall of the machine body 1 is rotatably connected with an axial flow impeller 6, and a rotating shaft of the axial flow impeller 6 is coaxially and fixedly connected with the material stirring wheel 4.

The lateral wall of organism 1 has seted up the groove of bleeding 7, and it has the fan of bleeding 8 to rotate to be connected with on the groove of bleeding 7 inner wall, and the pivot of fan of bleeding 8 and the coaxial fixed connection of stirring wheel 4, and the lateral wall of stirring wheel 4 is seted up and is led the air duct 11 communicating with feed inlet 5, it needs to explain, as shown in fig. 2, lead the air duct 11 and constitute for the straight flute of a horizontal direction and the straight flute of a plurality of vertical directions, and the straight flute of vertical direction communicates with each other with each feed inlet 5.

The air guide groove 11 is rotatably connected with an air outlet pipe 9, the side wall of the air outlet pipe 9 is provided with a first through hole 91, the air outlet pipe 9 is communicated with the inside of the air exhaust groove 7, the machine body 1 is provided with an air inlet pipe 10 communicated with the inside of the air exhaust groove 7, and the air inlet end of the air inlet pipe 10 is vertically downward.

When the device is used, seeds are placed in the storage tank 2 in advance. When the unmanned aerial vehicle flies, the oncoming airflow pushes the axial flow impeller 6 to rotate circularly and drives the material stirring wheel 4 to rotate synchronously. The seeds in the storage tank 2 continuously fall into the feed inlets 5 under the action of gravity and are continuously sprinkled along with the rotation of the material stirring wheel 4. The cylindrical shape of the material poking wheel 4 has extremely small resistance when rotating, and the resistance can be almost ignored, so that seeds can be spilled smoothly without blockage. Meanwhile, the seed can not generate larger acting force, so that the damage to the seed is greatly reduced, and the survival rate of the seed is effectively improved. It is worth mentioning in addition that, seeding speed becomes forward with unmanned aerial vehicle airspeed and closes, and unmanned aerial vehicle flies the faster promptly, then seeding speed accelerates, can not lead to the seed to distribute too densely or sparsely, makes the seeding more even, both improves seed survival rate and can guarantee output again

Meanwhile, the kick-off wheel 4 still will drive 8 synchronous rotations of extraction fan, can constantly follow the air intake pipe 10 suction, discharge by the through-hole 91 on the outlet duct 9 again, because the outlet duct 9 rotates and sets up on air guide groove 11 inner wall, the kick-off wheel 4 rotates and can not drive the outlet duct 9 and rotate, consequently, from the outlet duct 9 combustion gas flow vertical downwards all the time, so can produce a vertical decurrent air current and blow to the seed that spills, let and spill more smoothly, do not influenced by environment and unmanned aerial vehicle wind field.

Example two:

referring to fig. 3-4, the difference from the first embodiment is that a strip-shaped groove 12 communicating the storage tank 2 and the rotary chute 3 is formed in a side wall of the machine body 1, sliding grooves 13 are formed in two opposite inner walls of the strip-shaped groove 12, a baffle 14 is slidably connected to the sliding grooves 13, a second through hole 15 is formed in the upper end of the baffle 14, a driving device for driving the baffle 14 to move is installed in the second through hole 15, the driving device includes a magnetic ring 16 embedded in an inner wall of the second through hole 15, and an iron sheet 17 is fixedly connected to the bottom of the feed inlet 5.

It should be noted that, the baffle 14 is very close to the kick-off wheel 4, and the seeds can not be stacked after falling into the feed inlet 5, so as to prevent the seeds from being damaged when the kick-off wheel 4 rotates. Further, through setting up drive arrangement and making baffle 14 reciprocating motion round trip, still can make the seed in the stock chest 2 fall into feed inlet 5 through second through-hole 15 in, effectively prevent to block up the condition and take place.

Since in the first embodiment, the material-stirring wheel 4 generates a tangential force on its circumferential side wall when rotating, it is easy to press a part of the seeds at the edge of the material-stirring wheel 4. In the embodiment, when the kick-out wheel 4 rotates, the iron sheets 17 sequentially pass over the magnetic ring 16, so that the baffle 14 slides back and forth under the action of magnetic force.

Therefore, when the seeds in the storage tank 2 fall down, the seeds firstly fall on the baffle plate 14, the second through holes 15 are continuously exposed along with the left and right movement of the baffle plate 14, and the seeds above the baffle plate 14 can fall into the feed inlet 5 through the second through holes 15 and are spilled along with the rotation of the material stirring wheel 4. In this embodiment, the material stirring wheel 4 can not generate any acting force on the seeds when rotating, and the protection effect of the device on the seeds is further improved.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
