Description

種籾播種機Seed paddy seeder
　本発明は、種籾を播種する種籾播種機に関し、更に具体的には、ドローンなどの無人飛行体やトラクタなどの移動体に搭載するための種籾播種機に関する。 The present invention relates to a seed rice seeding machine for sowing seed rice, and more specifically, to a seed rice seeding machine for mounting on an unmanned aerial vehicle such as a drone or a moving body such as a tractor.
　近年、例えば、トラクターのロワ・リンク部に取り付けて、空気の吹き入れにより覆土へ点播する点播式播種機が開示されている（特許文献１）。また、農薬散布用無人航空機に関する技術も多数開示されている。例えば、特許文献２の無人飛行機の飛行経路制御システム及び無人飛行機の飛行経路制御方法がある。 In recent years, for example, a point-seeding type seeding machine that is attached to a lower link portion of a tractor and is spot-sown on a soil cover by blowing air has been disclosed (Patent Document 1). In addition, many technologies related to unmanned aerial vehicles for spraying pesticides are also disclosed. For example, there are a flight path control system for an unmanned aerial vehicle and a flight path control method for an unmanned aerial vehicle according to Patent Document 2.

　特許文献１に記載されたトラクター取り付け型の播種機は、乗車している運転者がトラクターの移動方向や速度を調整しながら手動で播種機を操作することで、条播（一定間隔で種籾をまくこと）することができる。しかしながら、同じ機能の播種機を無人航空機に搭載できたとしても、操縦者は、離れた場所で操作しているため、条播したい位置、方向、タイミングで種籾を連続射出できない。 The tractor-mounted seeding machine described in Patent Document 1 allows the driver on board to manually operate the seeding machine while adjusting the moving direction and speed of the tractor to sow seeds at regular intervals. That) can be done. However, even if a seeder with the same function can be mounted on an unmanned aerial vehicle, the operator cannot continuously inject seeds at the desired position, direction, and timing because the operator operates the seeds at a remote location.
　また、特許文献２に記載されたような空中からの播種の場合、従来の播種機のような地面へ溝をつけるためのガイドがないため、種籾を地中に埋めることができない。エアガンのような原理で打ち付ける手法（エアコッキング方式）では、種籾一粒ごとにスポット圧力を与えない限り、空気は地面に当たると平行に流れてしまうため（層流という）、大量の籾殻を打ち付けようとしても吹き飛んでしまうという課題がある。 Further, in the case of sowing from the air as described in Patent Document 2, the seed paddy cannot be buried in the ground because there is no guide for making a groove in the ground like a conventional sowing machine. In the method of hitting with the principle like an air gun (air cocking method), unless spot pressure is applied to each grain of rice seeds, the air will flow in parallel when it hits the ground (called laminar flow), so let's hit a large amount of rice husks. However, there is a problem that it will be blown away.

The recess 40 is for receiving and transporting the seed paddy 110 sent from the seed paddy tank 14.
　前記連結部２６は、種籾タンク１４のホッパ２０から落下してくる種籾１１０を、前記送り出しケース３２内の送り出しドラム３８の各列３８Ａ～３８Ｄに振り分ける。 The connecting portion 26 distributes the seed paddy 110 falling from the hopper 20 of the seed paddy tank 14 to the rows 38A to 38D of the delivery drum 38 in the delivery case 32.
　前記送り出しケース３２の下方には、送り出しベース５０が設けられている。送り出しベース５０は、図２に示すように、ケース５２を有しており、ケース５２は、種籾１１０を各送り出しホース７０Ａ～７０Ｄに送り出しためのホース接続口５４Ａ～５４Ｄを有する。前記送り出しケース３２とホース接続口５４Ａ～５４Ｄは、送り出しドラム３８の各列３８Ａ～３８Ｄに対応する送り出し通路３４Ａ～３４Ｄによって接続されている。 A delivery base 50 is provided below the delivery case 32. As shown in FIG. 2, the delivery base 50 has a case 52, and the case 52 has hose connection ports 54A to 54D for feeding the seed paddy 110 to the respective delivery hoses 70A to 70D. The delivery case 32 and the hose connection ports 54A to 54D are connected by delivery passages 34A to 34D corresponding to the respective rows 38A to 38D of the delivery drum 38.
　ホース接続口５４Ａには、例えば、送り出しホース７０Ｂの一端が接続され、ホース接続口５４Ｂには、例えば、送り出しホース７０Ａの一端が接続される。また、ホース接続口５４Ｃには、例えば、送り出しホース７０Ｄの一端が接続され、ホース接続口５４Ｃには、例えば、送り出しホース７０Ｃの一端が接続される。 For example, one end of the delivery hose 70B is connected to the hose connection port 54A, and one end of the delivery hose 70A is connected to the hose connection port 54B, for example. Further, for example, one end of the delivery hose 70D is connected to the hose connection port 54C, and one end of the delivery hose 70C is connected to the hose connection port 54C, for example.
　前記送り出しホース７０Ａ～７０Ｄは、支持フレーム１２に設けられた支持パイプ１２Ｃに支持されている。また、前記ホース接続口５４Ａ～５４Ｄには、空気供給管６０と、空気供給管６０から分岐した空気供給管６２、６４によって、図３に示すようにブロワ５６から空気が送られ、送り出しホース７０Ａ～７０Ｄ内の種籾１１０は空気で輸送され、シューターユニット８０Ａ～８０Ｄまで送られる。ブロワ５６の駆動は、コントローラ１２０により制御される。 The delivery hoses 70A to 70D are supported by a support pipe 12C provided on the support frame 12.

　このような送り出し機構３０により、送り出しモータ３６の回転によって、４つのシューターユニット８０Ａ～８０Ｄに、平等に種籾１１０を送り出すことができる。また、送り出しモータ３６の回転速度によって、種籾１１０の送り出し量を調整可能である。送り出しモータ３６の駆動は、コントローラ１２０により制御される。 With such a delivery mechanism 30, the seed paddy 110 can be equally delivered to the four shooter units 80A to 80D by the rotation of the delivery motor 36. Further, the feeding amount of the seed paddy 110 can be adjusted by the rotation speed of the feeding motor 36. The drive of the delivery motor 36 is controlled by the controller 120.
　次に、図５及び図６を参照して、シューターユニット８０Ａ～８０Ｄについて説明する。なお、シューターユニット８０Ａ～８０Ｄの構成は基本的に同様のため、以下では、シューターユニット８０Ａを例に挙げて説明する。図５は、本実施形態のシューターユニットの構成を示す外観斜視図である。図６は、図５を＃Ａ－＃Ａ線に沿って切断し、矢印方向に見た断面図である。 Next, the shooter units 80A to 80D will be described with reference to FIGS. 5 and 6. Since the configurations of the shooter units 80A to 80D are basically the same, the shooter unit 80A will be described below as an example. FIG. 5 is an external perspective view showing the configuration of the shooter unit of the present embodiment. FIG. 6 is a cross-sectional view of FIG. 5 cut along the lines # A- # A and viewed in the direction of the arrow.
　シューターユニット８０Ａは、送り出しホース７０Ａの他端側に接続されており（図１参照）、種籾１１０を播種するものである。本発明のシューターユニット８０Ａは、歯車の回転によって生じる遠心力により、種籾１１０を下向きに打ち込むことを特徴としている。 The shooter unit 80A is connected to the other end side of the delivery hose 70A (see FIG. 1), and seeds 110 seeds are sown. The shooter unit 80A of the present invention is characterized in that the seed paddy 110 is driven downward by the centrifugal force generated by the rotation of the gear.
　シューターユニット８０Ａは、略円筒状のシューターケース８４と、シューターケース８４内に配置された回転可能なシューターフィン１００（シューター歯車）と、シューターフィン１００を回転させるシューターモータ９０と、シューターノズル９４により構成されている。シューターケース８４は、蓋８６により開閉可能となっている。また、シューターケース８４及びシューターノズル９４は、ブラケット８２により支持フレーム１２に固定されている。 The shooter unit 80A is composed of a substantially cylindrical shooter case 84, a rotatable shooter fin 100 (shooter gear) arranged in the shooter case 84, a shooter motor 90 for rotating the shooter fin 100, and a shooter nozzle 94. Has been done. The shooter case 84 can be opened and closed by the lid 86. Further, the shooter case 84 and the shooter nozzle 94 are fixed to the support frame 12 by the bracket 82.
　例えば、図１に示すように、シューターユニット８０Ａは、支持パイプ１２Ｃの左側に固定されている。また、シューターユニット８０Ｂは、支持台１２Ｂの左側に固定され、シューターユニット８０Ｃは、支持台１２Ｃの右側に固定されている。また、シューターユニット８０Ｄは、支持パイプ１２Ｃの右側に固定されている。 For example, as shown in FIG. 1, the shooter unit 80A is fixed to the left side of the support pipe 12C. Further, the shooter unit 80B is fixed to the left side of the support base 12B, and the shooter unit 80C is fixed to the right side of the support base 12C. Further, the shooter unit 80D is fixed to the right side of the support pipe 12C.
　シューターケース８４内のシューターフィン１００は、複数の羽根１０２を有する回転体であって、シューターモータ９０により回転可能となっている。 The shooter fin 100 in the shooter case 84 is a rotating body having a plurality of blades 102, and can be rotated by the shooter motor 90.
　シューターノズル９４は、移動体に搭載されたときに上下方向を向き、かつ、シューターケース８４の右半分と重なり合うように配置されている。また、シューターノズル９４は、上端のホース接続口９６に送り出しホース７０Ａの他端が接続され、下端の射出口９８から種籾１１０が下方に射出される。 The shooter nozzle 94 is arranged so as to face in the vertical direction when mounted on the moving body and to overlap the right half of the shooter case 84. Further, in the shooter nozzle 94, the other end of the delivery hose 70A is connected to the hose connection port 96 at the upper end, and the seed paddy 110 is ejected downward from the injection port 98 at the lower end.
　シューターノズル９４は、図６に示すように、シューターケース８４と重なり合う部分の内側は除去されている。このため、シューターフィン１００が回転しても羽根１０２がシューターノズル９４にぶつかることなく、シューターノズル９４から落下してきた種籾１１０を、各羽根１０２によって下方に送ることができる。 As shown in FIG. 6, the shooter nozzle 94 has the inside of the portion overlapping with the shooter case 84 removed. Therefore, even if the shooter fin 100 rotates, the blades 102 do not hit the shooter nozzle 94, and the seed paddy 110 that has fallen from the shooter nozzle 94 can be sent downward by each blade 102.
　このようなシュータユニット８０Ａは、シューターモータ９０のモータスピードにより、種籾１１０を打ち込む深度を調整可能である。シューターモータ９０は、前記コントローラ１２０に接続され、その駆動が制御される。他のシューターユニット８０Ｂ～８０Ｄについても同様の構成となっている。 In such a shooter unit 80A, the depth at which the seed paddy 110 is driven can be adjusted by the motor speed of the shooter motor 90. The shooter motor 90 is connected to the controller 120 and its drive is controlled. The other shooter units 80B to 80D have the same configuration.
　なお、コントローラ１２０は、例えば、種籾播種装置１０をドローン（図示せず）に搭載した場合には、ドローンの操縦者によって遠隔で制御されてもよい。 Note that the controller 120 may be remotely controlled by the drone operator, for example, when the seed paddy seeding device 10 is mounted on a drone (not shown).
　次に、本実施形態の作用を説明する。図示しないドローンには、種籾タンク１４に種籾１１０を収納した種籾播種機１０が搭載される。種籾播種機１０の送り出しモータ３６、ブロワ５６、シューターモータ９０は、コントローラ１２０によって駆動が制御される。コントローラ１２０は、ドローンの操縦者によって遠隔で制御される。 Next, the operation of this embodiment will be described. A drone (not shown) is equipped with a seed paddy seeding machine 10 in which the seed paddy 110 is housed in a seed paddy tank 14. The drive of the feed motor 36, the blower 56, and the shooter motor 90 of the seed paddy seeder 10 is controlled by the controller 120. The controller 120 is remotely controlled by the drone operator.
　播種を行う場所までドローンを飛行させたら、制御装置１２０は、シューターユニット８０Ａ～８０Ｄからの種籾１１０の射出を行いながら飛行を行う。具体的には、まず、種籾タンク１４のホッパ２０から連結部２６を介して送り出し機構３０の送り出しケース３２内に種籾１１０を送る。送られた種籾１１０は、送り出しケース３２内の送り出しドラム３８の４つの列３８Ａ～３８Ｄの上に振り分けられて落下する。 After flying the drone to the place where sowing is performed, the control device 120 flies while ejecting the seed paddy 110 from the shooter units 80A to 80D. Specifically, first, the seed paddy 110 is fed from the hopper 20 of the seed paddy tank 14 into the delivery case 32 of the delivery mechanism 30 via the connecting portion 26. The sent seed paddy 110 is distributed onto the four rows 38A to 38D of the delivery drum 38 in the delivery case 32 and falls.
　送り出しドラム３８の各列３８Ａ～３８Ｄの上に落下した種籾１１０は、各列３８Ａ～３８Ｄに、回転方向に等間隔で形成された凹部４０に収容され、送り出しドラム３８の回転によって、下方に配置された送り出しベース５０の４つのホース接続口５４Ａ～５４Ｄにそれぞれ搬送される。 The seed pad 110 that has fallen onto each row 38A to 38D of the delivery drum 38 is housed in recesses 40 formed at equal intervals in the rotation direction in each row 38A to 38D, and is arranged downward by the rotation of the delivery drum 38. It is conveyed to each of the four hose connection ports 54A to 54D of the delivery base 50.
　例えば、列３８Ａの凹部４０に収容された種籾１１０は、送り出し通路３４Ａを介して、送り出しベース５０のホース接続口５４Ａに送られ、列３８Ｂの凹部４０に収容された種籾１１０は、送り出し通路３４Ｂを介して送り出しベース５０のホース接続口５４Ｂに送られる。また、列３８Ｃの凹部４０に収容された種籾１１０は、送り出し通路３４Ｃを介して、送り出しベース５０のホース接続口５４Ｃに送られ、列３８Ｄの凹部４０に収容された種籾１１０は、送り出し通路３４Ｄを介して送り出しベース５０のホース接続口５４Ｄに送られる。 For example, the seed paddy 110 housed in the recess 40 of the row 38A is sent to the hose connection port 54A of the feeding base 50 via the feeding passage 34A, and the seed paddy 110 housed in the recess 40 of the row 38B is sent to the feeding passage 34B. It is sent to the hose connection port 54B of the delivery base 50 via. Further, the seed paddy 110 housed in the recess 40 of the row 38C is sent to the hose connection port 54C of the feeding base 50 via the feeding passage 34C, and the seed paddy 110 housed in the recess 40 of the row 38D is sent to the feeding passage 34D. It is sent to the hose connection port 54D of the delivery base 50 via.
　ホース接続口５４Ａには、送り出しホース７０Ｂの一端が接続され、ホース接続口５４Ｂには、送り出しホース７０Ａの一端が接続されている。また、ホース接続口５４Ｃには、送り出しホース７０Ｄの一端が接続され、ホース接続口５４Ｄには、送り出しホース７０Ｃの一端が接続されている。 One end of the delivery hose 70B is connected to the hose connection port 54A, and one end of the delivery hose 70A is connected to the hose connection port 54B. Further, one end of the delivery hose 70D is connected to the hose connection port 54C, and one end of the delivery hose 70C is connected to the hose connection port 54D.
　また、前記ホース接続口５４Ａ～５４Ｄには、空気供給管６０と、空気供給管６０から分岐した空気供給管６２、６４によって、図３に示すようにブロワ５６から空気が送られ、送り出しホース７０Ａ～７０Ｄを通ってシューターユニット８０Ａ～８０Ｄまで移動するように、種籾１１０が搬送される。 Further, as shown in FIG. 3, air is sent from the blower 56 to the hose connection ports 54A to 54D by the air supply pipe 60 and the air supply pipes 62 and 64 branched from the air supply pipe 60, and the delivery hose 70A The seed paddy 110 is transported so as to move to the shooter units 80A to 80D through the 70D.
　このような送り出し機構３０により、送り出しモータ３６の回転によって、４つのシューターユニット８０Ａ～８０Ｄに、平等に種籾１１０を送り出すことができる。また、送り出しドラム３６の回転速度によって、種籾１１０の送り出し量が調整される。 With such a delivery mechanism 30, the seed paddy 110 can be equally delivered to the four shooter units 80A to 80D by the rotation of the delivery motor 36. Further, the feeding amount of the seed paddy 110 is adjusted by the rotation speed of the feeding drum 36.
　シューターユニット８０Ａ～８０Ｄに送られた種籾１１０は、シューターノズル９４の上端のホース接続口９６からシューターノズル９４内に入る。シューターノズル９４に入った種籾１１０は、シューターケース８４と重なり合う部分から、シューターフィン１００上に落下し、シューターフィン１００の各羽根１０２の間の隙間の空間１０４に入り、シューターフィン１００の回転による遠心力により、図６に示すように下方に射出される。 The seed paddy 110 sent to the shooter units 80A to 80D enters the shooter nozzle 94 from the hose connection port 96 at the upper end of the shooter nozzle 94. The seed paddy 110 that has entered the shooter nozzle 94 falls onto the shooter fin 100 from a portion that overlaps with the shooter case 84, enters the space 104 of the gap between the blades 102 of the shooter fin 100, and is centrifuged by the rotation of the shooter fin 100. Due to the force, it is ejected downward as shown in FIG.
　より具体的には、シューターフィン１００が高速で回転することにより、種籾１１０は、各羽根１０２の下に集まり、遠心力で外側に寄る。従って、円の仕切りがなくなった箇所（図６に破線で示す開口部８８）でリリースされ、シューターフィン１００で押される速度で、下向きに打ち込まれる。 More specifically, as the shooter fin 100 rotates at high speed, the seed paddy 110 gathers under each blade 102 and moves outward by centrifugal force. Therefore, it is released at the place where the partition of the circle disappears (the opening 88 shown by the broken line in FIG. 6), and is driven downward at the speed pushed by the shooter fin 100.
　なお、シューターノズル９４を落下する種籾１１０は、全てがシューターフィン１００の外側に寄るわけではない。種籾１１０にかかる力は、回転モーメント、すなわち、シューターモータ９０の回転する力（トルク）×回転中心からの距離となるため、シューターフィン１００の内側（回転軸側）の種籾１１０は、回転モーメント不足で土への打ち込みの力が不足することになる。 Note that not all of the seed paddy 110 that falls on the shooter nozzle 94 approaches the outside of the shooter fin 100. Since the force applied to the seed pad 110 is the rotational moment, that is, the rotational force (torque) of the shooter motor 90 × the distance from the center of rotation, the seed pad 110 inside the shooter fin 100 (on the rotation axis side) has insufficient rotational moment. Therefore, the power to drive into the soil will be insufficient.
　そこで、本発明では、回転不足の内側の種籾１１０は、開口部８８の下端でシューターケース８４に引っ掛かり、さらに１周回ることでモーメントが増加し、打ち込み時には、十分な力が加わった状態で射出される仕組みとなっている。なお、種籾１１０を打ち込む深度は、シューターモータ９０のモータスピードにより調整可能である。 Therefore, in the present invention, the seed paddy 110 on the inner side of the insufficient rotation is caught by the shooter case 84 at the lower end of the opening 88, and the moment is increased by making one more round, and the seed paddy 110 is ejected in a state where a sufficient force is applied at the time of driving. It is a mechanism to be done. The depth at which the seed paddy 110 is driven can be adjusted by the motor speed of the shooter motor 90.
　＜効果＞・・・以上説明した実施形態によれば、移動体に搭載される種籾播種装置１０において、種籾が収納され、内部にホッパが設けられた種籾タンク１４と、種籾タンク１４のホッパ２０の出口に接続されており、前記種籾タンク１４から受け入れた種籾１１０を送り出しホース７０Ａ～７０Ｄの一端側に送り出す送り出し機構３０と、送り出しホース７０Ａ～７０Ｄの他端側に接続されており、種籾１１０を播種するシューターユニット８０Ａ～８０Ｄと、送り出しホース内７０Ａ～７０Ｄの種籾を、シューターユニット８０Ａ～８０Ｄに送るブロワ５６と、前記送り出し機構３０、シューターユニット８０Ａ～８０Ｄ及びブロワ５６に接続されており、播種の強度及び播種量を制御するコントローラ１２０と、前記種籾タンク、送り出し機構、シューターユニット、ブロワ及びコントローラを支持する支持フレーム１２と、を備え、シューターユニット８０Ａ～８０Ｄは、歯車の回転によって生じる遠心力により、種籾を下向きに打ち込むこととした。これにより、条播したい位置、方向、タイミングで、種籾１１０を連続射出することができ、かつ、種籾を一定の深さに打ち込むことができる。 <Effect> ... According to the embodiment described above, in the seed paddy sowing device 10 mounted on the moving body, the seed paddy tank 14 in which the seed paddy is stored and a hopper is provided inside, and the hopper 20 of the seed paddy tank 14 The seed paddy 110 is connected to the outlet of the seed paddy tank 14 and is connected to one end side of the feeding hose 70A to 70D and the other end side of the feeding hose 70A to 70D. The shooter units 80A to 80D for sowing the seeds, the blower 56 for sending the seeds of 70A to 70D in the delivery hose to the shooter units 80A to 80D, and the delivery mechanism 30, the shooter units 80A to 80D and the blower 56 are connected to each other. The shooter units 80A to 80D include a controller 120 for controlling the seeding strength and the seeding amount, a paddy tank, a feeding mechanism, a shooter unit, a blower, and a support frame 12 for supporting the controller. The shooter units 80A to 80D are centrifugals generated by rotation of gears. It was decided to drive the seed paddy downward by force. As a result, the seed paddy 110 can be continuously ejected at the position, direction, and timing of the row sowing, and the seed paddy can be driven to a certain depth.
　また、本実施形態では、シューターユニット８０Ａ～８０Ｄは、略円筒状のシューターケース８４と、シューターケース８４内に回転可能に配置されており、複数の羽根１０２を有するシューターフィン１００と、シューターフィン１００を回転させるシューターモータ９０と、移動体に搭載されたときに上下方向を向き、かつ、シューターケース８４と重なり合うように配置され、上端側が送り出しホース７０Ａ～７０Ｄの他端側に接続され、下端側から前記種籾１１０を射出するシューターノズル９４と、を備えており、シューターノズル９４は、シューターケース８４と重なり合う部分が除去されている。 Further, in the present embodiment, the shooter units 80A to 80D are rotatably arranged in the shooter case 84 having a substantially cylindrical shape and the shooter case 84, and the shooter fin 100 having a plurality of blades 102 and the shooter fin 100. The shooter motor 90 that rotates the The shooter nozzle 94 for ejecting the seed paddy 110 is provided, and the portion of the shooter nozzle 94 that overlaps with the shooter case 84 is removed.
　そして、シューターフィン１００が高速で回転することにより、種籾１１０は、各羽根１０２の下に集まり、遠心力で外側に寄り、円の仕切りがなくなった開口部８８でリリースされ、シューターフィン１００で押される速度で、下向きに打ち込まれる。また、シューターフィン１００の内側（回転軸側）の回転モーメント不足の種籾１１０は、開口部８８の下端付近でシューターケース８４に引っ掛かり、さらに１周回ることでモーメントが増加する。このため、打ち込み時には、十分な力が加わった状態で射出することができる。 Then, as the shooter fin 100 rotates at high speed, the seed paddy 110 gathers under each blade 102, moves outward by centrifugal force, is released at the opening 88 where there is no circular partition, and is pushed by the shooter fin 100. It is driven downward at the speed at which it is driven. Further, the seed pad 110 having insufficient rotational moment inside the shooter fin 100 (on the rotation shaft side) is caught by the shooter case 84 near the lower end of the opening 88, and the moment is increased by making one more round. Therefore, at the time of driving, it is possible to inject with sufficient force applied.
　本実施形態の種籾播種機１０を無人航空機に搭載することにより、例えば、無人航空機による水稲栽培が可能となる。無人航空機は、地上走行型の農機に比べ、小型・軽量であるため、軽トラック等に積載可能であり、農機の移動が困難な中山間地や小区画ほ場、湿田や半湿田でほ場が乾かない地域、市街地近郊のほ場にも導入することが可能となる。また、無人航空機の自動飛行機能を活用すれば、操縦者は見守るだけで水稲直播が完了する。 By mounting the seed paddy sowing machine 10 of the present embodiment on an unmanned aerial vehicle, for example, paddy rice cultivation by an unmanned aerial vehicle becomes possible. Unmanned aerial vehicles are smaller and lighter than ground-based agricultural machines, so they can be loaded on light trucks, etc., and the fields are dry in mountainous areas, small plot fields, wet fields, and semi-wet fields where it is difficult for agricultural machines to move. It will be possible to introduce it to fields that are not available or in the suburbs of urban areas. In addition, if the automatic flight function of an unmanned aerial vehicle is utilized, the operator can complete the direct sowing of paddy rice just by watching.
