このようなドローン本体１０は、その大きさ及び形状を多様に変更することができるが、本発明では、従来技術によるドローンのいずれかの一様態のものであって、これ以上の詳細な説明は、明細書の簡略化のために省略することとする。 The size and shape of such a drone body 10 can be changed in various ways, but in the present invention, the drone body 10 is a uniform form of any of the drones according to the prior art, and further detailed description thereof will be given. , Will be omitted for the sake of simplification of the specification.

また、上述したドローン本体１０の下側には、貯蔵タンク２０が備えられている。この貯蔵タンク２０は、農耕地に散布する肥料や農薬を貯蔵している。ここで、肥料や農薬（以下、農薬のみ記載する）は、粉状、錠剤状、固形状のいずれか、またはこれらのうち、二つ以上が混合した状態であるものとする。 Further, a storage tank 20 is provided under the drone body 10 described above. The storage tank 20 stores fertilizers and pesticides to be sprayed on agricultural land. Here, fertilizers and pesticides (hereinafter, only pesticides are described) are in the form of powder, tablets, solids, or a mixture of two or more of these.

この貯蔵タンク２０は、その内部に貯蔵空間が設けられており、それぞれの側面が下側で集まるような逆三角錐状に形成される。これは、貯蔵タンク２０内の農薬が外部に散布されるとき、貯蔵タンク２０内に残っている農薬が下方に向かって集まるようにするためであり、これによって下側に集まった農薬は、後述する排出装置３０によって内部から外部に順次搬送されることができる。 The storage tank 20 is provided with a storage space inside, and is formed in an inverted triangular pyramid shape so that the side surfaces thereof gather on the lower side. This is to allow the pesticides remaining in the storage tank 20 to collect downward when the pesticides in the storage tank 20 are sprayed to the outside, and the pesticides collected on the lower side by this will be described later. It can be sequentially conveyed from the inside to the outside by the discharging device 30.

本発明では、貯蔵タンク２０を逆三角錐状に形成されているものとしたが、逆円錐又は逆四角錐、逆五角錐などに変更することもできる。また、図示されてはいないが、貯蔵タンク２０の一側には、内部に貯蔵されている農薬の貯蔵量を目視確認できるように目盛りを設けた透明窓を備えてもよい。 In the present invention, the storage tank 20 is formed in an inverted triangular pyramid shape, but it can be changed to an inverted cone, an inverted quadrangular pyramid, an inverted pentagonal pyramid, or the like. Further, although not shown, one side of the storage tank 20 may be provided with a transparent window provided with a scale so that the amount of pesticides stored inside can be visually confirmed.

また、図２及び図３を参照すると、上述した貯蔵タンク２０の上部面の一側には、蓋部２１が備えられる。この蓋部２１は、回動に応じて貯蔵タンク２０の貯蔵空間内に農薬を入れるための投入口の役割を担うものである。この蓋部２１は、本発明の一実施形態では回動式開閉型で製作されているが、スライド式開閉型で製作することもでき、もしくは、従来の技術による蓋部２１の形態のうちの一つに代替することもできる。 Further, referring to FIGS. 2 and 3, a lid portion 21 is provided on one side of the upper surface of the storage tank 20 described above. The lid portion 21 serves as a inlet for putting pesticides into the storage space of the storage tank 20 in response to rotation. Although the lid portion 21 is manufactured by a rotary opening / closing type in one embodiment of the present invention, it can also be manufactured by a sliding opening / closing type, or among the forms of the lid portion 21 by the conventional technique. It can be replaced with one.

そして、前記貯蔵タンク２０の一側端には、排出装置３０が作動可能に備えられている。この排出装置３０は、貯蔵空間内の下側の農薬を上側に搬送させて外部に排出する役割を担う。 A discharge device 30 is operably provided at one end of the storage tank 20. The discharge device 30 plays a role of transporting the lower pesticide in the storage space to the upper side and discharging it to the outside.

この排出装置３０は、逆三角錐状の前記貯蔵タンク２０の一側端に設けられており、その下端が貯蔵空間の下端側に近接して位置されることで、貯蔵空間内で下側に集まる農薬が順次下側から上側に搬送されて排出できるようにする。 The discharge device 30 is provided at one side end of the storage tank 20 having an inverted triangular pyramid shape, and the lower end thereof is located close to the lower end side of the storage space so that the discharge device 30 is located downward in the storage space. The pesticides that collect are sequentially transported from the lower side to the upper side so that they can be discharged.

この排出装置３０は、貯蔵タンク２０の一側端の上側に回転可能に設けられるアイドルローラ３１と、貯蔵タンク２０の一側端の上側とアイドルローラ３１との間に形成される排出口３２と、貯蔵タンク２０の一側端の下側端部に回転可能に設けられる駆動ローラ３３と、駆動ローラ３３にその駆動軸が接続して駆動することによって駆動ローラ３３が回転するようにする駆動モータ３４と、アイドルローラ３１及び駆動ローラ３３に巻回されて駆動モータ３４の駆動に応じて回転しながら、貯蔵空間内の農薬が排出口３２を通じて外部に排出されるようにするベルト３５と、ベルト３５の外側に設けられてベルト３５を保護するガード部材３６と、を含む。ここで、駆動モータ３４の作動の要否と作動速度などの制御は、無線操縦機により行われるものとする。 The discharge device 30 includes an idle roller 31 rotatably provided above one side end of the storage tank 20, and a discharge port 32 formed between the upper side of one side end of the storage tank 20 and the idle roller 31. , A drive roller 33 rotatably provided at the lower end of one side end of the storage tank 20, and a drive motor that rotates the drive roller 33 by connecting the drive shaft to the drive roller 33 and driving the drive roller 33. A belt 35 and a belt that are wound around the idle roller 31 and the drive roller 33 and rotate in response to the drive of the drive motor 34 so that pesticides in the storage space are discharged to the outside through the discharge port 32. It includes a guard member 36 provided on the outside of the 35 to protect the belt 35. Here, it is assumed that the radio controller controls the necessity of operating the drive motor 34 and the operating speed.

前記駆動モータ３４が作動する際、駆動モータ３４の軸とその軸が噛合している駆動ローラ３３が回転し、駆動ローラ３３とベルト３５とによって接続されたアイドルローラ３１も同時に回転しながら、ベルト３５が一方向に回転する。このとき、ベルト３５の回転方向は、貯蔵空間の内部で下側から上側に、貯蔵空間の外部で上側から下側に移動しながら、ベルト３５全体が連続回転する。したがって、貯蔵空間内で下側から上側に移動するベルト３５によって粉状または錠剤状の農薬がベルト３５の上で搬送され、排出口３２を通じて外部に排出できる。ここで、ベルト３５の上には、その幅方向で農薬を載置するための突出部（図示せず）を設けており、下側から上側に移動する農薬をベルト３５上から滑らずに排出口３２まで搬送することができるようにしてもよい。 When the drive motor 34 operates, the shaft of the drive motor 34 and the drive roller 33 in which the shaft meshes with each other rotate, and the idle roller 31 connected by the drive roller 33 and the belt 35 also rotates at the same time while rotating the belt. 35 rotates in one direction. At this time, the rotation direction of the belt 35 is that the entire belt 35 continuously rotates while moving from the lower side to the upper side inside the storage space and from the upper side to the lower side outside the storage space. Therefore, the powdery or tablet-like pesticide is conveyed on the belt 35 by the belt 35 that moves from the lower side to the upper side in the storage space, and can be discharged to the outside through the discharge port 32.

以下では、図５を参照として、本発明の一実施形態に係るコンベア式排出装置を有する農業用ドローン１の全体的な作動方法について詳細に説明する。 In the following, with reference to FIG. 5, the overall operation method of the agricultural drone 1 having the conveyor type discharge device according to the embodiment of the present invention will be described in detail.

先ず、ドローン本体１０の脚部１２に設けられている貯蔵タンク２０の蓋部２１を開き、貯蔵空間内に農薬を投入する。その後、無線操縦機を用いて農薬を散布すべき農耕地の上空でドローン本体１０が飛行するようにする。 First, the lid 21 of the storage tank 20 provided on the leg 12 of the drone body 10 is opened, and the pesticide is put into the storage space. After that, the drone body 10 is made to fly over the farmland where the pesticide should be sprayed by using the radio control machine.

ドローン本体１０が、農薬を撒く農耕地の上空に到着すると、無線操縦機で排出装置３０の駆動モータ３４を作動させる。駆動モータ３４が作動すると、駆動モータ３４の軸とその軸が噛合している駆動ローラ３３が回転し、駆動ローラ３３とベルト３５とによって連結されているアイドルローラ３１も同時に回転しながらベルト３５が一方向に回転する。このとき、ベルト３５の回転方向は、貯蔵空間の内部で下側から上側に、貯蔵空間の外部で上側から下側に移動しながら、ベルト３５全体が連続回転することになる。 When the drone body 10 arrives above the farmland where the pesticide is sprayed, the drive motor 34 of the discharge device 30 is operated by the radio control device. When the drive motor 34 operates, the shaft of the drive motor 34 and the drive roller 33 in which the shaft meshes with each other rotate, and the idle roller 31 connected by the drive roller 33 and the belt 35 also rotates at the same time while the belt 35 moves. Rotate in one direction. At this time, the rotation direction of the belt 35 is that the entire belt 35 continuously rotates while moving from the lower side to the upper side inside the storage space and from the upper side to the lower side outside the storage space.

貯蔵空間内で下側から上側に移動するベルト３５に沿って粉状または錠剤状の農薬が連続して搬送され、搬送された農薬は、排出口３２を通じて外部に排出され、農耕地にまんべんなく散布される。 Powdered or tablet-shaped pesticides are continuously transported along a belt 35 that moves from the lower side to the upper side in the storage space, and the transported pesticides are discharged to the outside through the discharge port 32 and evenly sprayed on the farmland. Will be done.

そして農耕地全体に農薬が撒かれるまでドローン本体１０は、農耕地の上空で繰り返し飛行する。 Then, the drone body 10 repeatedly flies over the cultivated land until the pesticide is spread over the cultivated land.

以上のようなコンベア式排出装置を有する農業用ドローン１によれば、貯蔵タンク２０の内部に入った農薬がコンベアベルト式排出装置３０によって下側から上側に順次搬送され、搬送された農薬が外部に定量排出できるため、農薬を所定の散布領域内にムラなく均一に散布することができる。 According to the agricultural drone 1 having the conveyor type discharge device as described above, the pesticides that have entered the inside of the storage tank 20 are sequentially transported from the lower side to the upper side by the conveyor belt type discharge device 30, and the transported pesticides are externally transported. Since the pesticide can be discharged in a fixed amount, the pesticide can be evenly and evenly sprayed in the predetermined spraying area.
