491733 五、發明說明（1) <發明所屬技術領域> 本發明係關於藥液喷霧車，更詳細的關於一種藥液 噴霧車，主要以手壓使其行走於蔬菜田等田畝之壟溝，以 搭載於車體之動力藥液喷霧裝置將藥液劑散佈於作物，改 良車輪機構、藥液箱的構造、喷霧機構等，使使用方便性 提昇。 <習知之技術> 習知，背負型的喷霧機對於作業者，由於為負擔過 大之重勞動，所以具有行走車輪手壓形之藥液喷霧車被提 案出來。該種類之藥液喷霧車，在側面作成並排寬度較廣 之2輪車與4輪車後，雖移動較容易，但在田畝之埂間較細 小的場合，由於無法進入其中，要使藥液飛到很遠，就必 須使用在末端附上喷嘴之較長軟管進行作業，無論何種場 合不僅需要較大之動力，藥液也無法散佈至作物的葉子裡 面，且因較長之軟管有可能招致損害作物之虞慮。 為此，習知，1輪車型之藥液噴霧車，在特開平3-296458 號公報、實公昭63-27804號公報、實公平夂1〇84號公報、 實公平4-41960號公報、實公平7·559〇9號公報等中多數被 提案出來。 <發明欲解決的課題> 但是，在此等之1輪車型之喷霧機也具有以下之問題 點。 首先，為了使其行走於田畝之埂間被作成丨輪車，但 作成為1輪車後，左右很難取得平衡，在運搬時需要花费491733 V. Description of the invention (1) < Technical Field to which the Invention belongs > The present invention relates to a medicinal liquid spraying vehicle, and more specifically to a medicinal liquid spraying vehicle, which is mainly driven by hand pressure to a vegetable field such as a vegetable field. The power liquid medicine spraying device mounted on the vehicle body is used to distribute the liquid medicine agent to the crops, and the wheel mechanism, the structure of the liquid medicine tank, the spraying mechanism are improved, and the convenience of use is improved. < Known technology > It is known that a knapsack sprayer is a heavy-duty laborer for the operator, so a liquid medicine sprayer with a hand-shaped pressing wheel is proposed. This type of medicinal liquid spray truck is made side-by-side with two-wheeler and four-wheeler with a wider width, although it is easier to move, but in the small area between the acres, it is impossible to enter. If the liquid flies far, you must use a long hose with a nozzle attached to the end. In any case, not only a large power is required, the liquid medicine cannot be spread into the leaves of the crop, and because of the long softness There is a risk of crop damage. For this reason, it is known that the chemical liquid sprayer for a one-wheel vehicle model is disclosed in JP-A-3,296,458, Shigong Sho 63-27804, Shihkei No. 1084, Shihkei 4-41960, and Most of them were proposed in Fair No. 7.559009. < Problems to be Solved by the Invention > However, the sprayers of such one-wheeled vehicles also have the following problems. First, in order to make it walk between acres, it is made a wheeler. However, after it is made as a one-wheeler, it is difficult to achieve a balance between the left and right sides.
五、發明說明（2) 相當大的力量，作業員在操作把手的負擔變大。 另外，在特開平3-296458號公報及實公平7-55909號 △報所述之藥液噴霧車，係在側面看略圓形之藥液箱的外 周面形成覆蓋車輪之構造，構造較複雜，不僅製造成本較 同由於旁部較尚安定性不佳，所以在移動時具有所謂很 難取得平衡之問題點。 在實公昭63-27804號公報、實公平3-1〇84號公報、實 公平4-41960號公報所述之散佈機的場合，由於在車輪上 載置藥液箱等，所以重心高度的不安定，作業上具有困難， 構造較複雜，製造成本變高。 如貫公平4-41960號公報所述之散佈機，在後部設置 對之靜止用的腳之構造的場合，由於比車輪寬度較寬所 以在畝間等之狹小的場所具有所謂無法停止喷霧機之問 題。 上述之問題點之外，在藥液喷霧車中，有必要將供 給至設置在車體之藥液箱内之藥液不殘留的用完，但在習 知之藥液箱要完全沒有殘液卻有其困難。 亦即’在藥液箱内使吸管垂下，將該吸管末端之吸 水口仏向箱底面放置，或將末端斜切置於箱底面，使藥液 以幫浦吸引。若為該構造後，在殘液變成較少時很難吸引 到最後’且因箱的傾斜與液體的搖動，使空氣進入吸管之 中’有可能使幫浦形成無吸引力，箱内之藥液的殘量變多。 如此’藥液的殘量變多之後，箱的洗淨不僅費工夫，殘留 的辰藥與下次使用之別的農藥混合，因而具有對作物造成 五、發明說明（3) 樂害之問題。 更進一步’在箱内由於將吸管置於箱的底面所以 ί目的傾斜與幫浦的震動、和吸管的末端因吸管的吸水壓力 吸著於箱底面與側面，有可能造成無法吸水。 更進步在使其行走在該種田故之硬間之藥液喷 霧車泥土 ’尼砂很谷易附著於車輪上，因而有必要將附 著之泥土與泥砂刮落。 1知係如第1〇Α，1〇Β囷所示，將長尺之鐵板Α與圓棒Β 配置成與車輪％之旋轉軸Wa相平行，作為用以刮落此等 之泥土與泥砂之刮土器。 但是，在由平行配置於上述旋轉轴之鐵板與圓棒所 形成之刮土器，當附著於車輪之泥土與泥砂變多之後，刮 土器破負荷相當大的力量，因而刮土器存在著具有破損之 問題。 更進一步’在藥液噴霧車，一般作業員把持與藥液 箱連通之軟管，由被安裝於軟管末端之喷嘴喷霧藥液。為 此，作業員有必要一面以手壓使藥液喷霧車行走，一面拿 著軟管進行散佈藥液之作業，在因箱的容量較大貯留於箱 内之藥液使車體變重的場合，作業者的負擔也變大。且， 有必要對南側田故之作物喷霧藥液的場合，在喷霧藥液至 一方側田故之作物後，必須要對另外一方側田畝喷霧藥 液，因而具有花費相當之作業時間與作業負擔之問題。 本發明係以提供一種可以解除上述所列舉之問題， 且使用方便之藥液喷霧車作為課題。 五、發明說明（4) 〈解決課題的手段> 為了解決上述課題，本發明係在第1提供一種藥液喷

均可以藉刮土器加以刮落。 特別是，上述刮土器之栓，其截面形狀最好作成向 車輪之圓周方向較長之橢圓形狀。如此，作成圓周方向之 較長橢圓形狀後，負載於栓之載重可以更小，同時圓周方 向較長可以提高刮落之效果。 五、發明說明（6) 更進一步，鋸齒形配置（亦即在車軸方向空出間隔， 同時在在圓周方向空出間隔配置）刮土器之栓後，栓錯開 接觸於泥土與泥砂的時間，加於栓的負荷可以更加減少。 刮土器之栓對於佔車輪之比例最好約為2〇%程度， 以該比例突設栓後，可以確實的將附著於車輪外周面之泥 土與泥砂刮落。 本發明係在第3提供一種藥液喷霧車，包含有：車體， 係設置有藥液箱；動力喷霧裝置，係搭載於該車體上；手 壓把手，係附設於上述車體上；及，行走車輪，係安裝在 上述車體；又在上述藥液箱的底面突設一對之肋部，在被 挾持於此等肋部之底面之略中心，設置形成最下點之凹

根之栓，在1個輪胎2根之栓14位相於圓周方向，使其接觸 於附著在車輪外周面之泥沙等。此等之栓14對於車輪寬之 比例，係作為約20%程度。 與車體2 —體成形設置之藥液箱8,係設置在由突設 上述車軸支撐部2a、2b之前端側，除了車體後部之動力源 搭載部之車體的中央領域，比較於車體2小型化，將藥液 箱8的容量作大。在該藥液箱8内充填藥液9後，藥液進入 比車輪3、4之車軸還下方，因而可以設定車體的重心於非 常低的位置，藉此可以安定的行走。 如第6A，B，C圖所示，在底面8a之中央部近旁對向突 設一對之殘液防止用肋部8b、8b，在被挾持於此等肋部8b、 12 49.1733 五、發明說明（ίο) 8b之底面8a之略中心，形成成為最下點之球狀的凹部8d。 在本實施型態，該凹部8d直徑為30mm〜80mm，最好為 50mm〜60mm ’深度為10mm〜30mm，最好為20mm〜25mm， 使其溜住所要量之藥液。 在上述最下點之凹部8d之周緣的一部凹設開口之載 面U形狀之吸管挾持溝8e。在該吸管挾持溝8e嵌入藥液吸 管15的末端近旁，使藥液吸管15的末端吸水口 i5a向凹部8d 之内部開口。在該狀態，末端吸水口 15a係被保持浮在凹 部8d内之狀態，防止藥液吸管〗5的末端吸附於底面。該藥

作為搭載於車體2之動力喷霧裝置，係在車體後部搭 載前述幫浦10、該幫浦驅動用之引擎11。如第1囷及第2圖 所示，幫浦10之吸引口係如前所述連接藥液吸管15，在連 接於吐出口之吐出管19分歧連接2條之軟管7A、7B。此等 2條之軟管7A、7B，係在車體2之上面側朝後部配管，並 分別連接於附設在車體2的前部上面之藥液噴霧喷嘴裝置6 之噴嘴附設管16(16A、16B)。 13 491733 五、發明說明（11) 各噴嘴附設管16A、16B，係作成可以將藥液噴霧至 分別多數畝U(在本實施型態1根之喷嘴附設管可以噴霧3 故’合計6畝）之作物程度之長度，空出間隔安裝多數之噴 嘴17(在本實施型態各3個）。此等之喷嘴π，係可以藉使 噴嘴旋轉停止喷射，且使用可以調節喷射方向者。 藥液喷霧喷嘴裝置6，或上述左右一對之喷嘴附設管 16A、16B，係作成可以藉固定於車體2上面之連桿式之升 降兼開關機構20調節高度及調節打開的角度。 亦即，升降兼開關機構20，係由支柱21、橫轴22、 連桿24A、24B、與連桿25A、25B所形成。該橫轴22，係 中央部可以自由升降外嵌於該支柱21;該連桿24A、24B， 係自由旋轉的軸著於該橫轴22的兩端；該連桿25A、25B， 係以栓26連結此等連桿24A、24B之他端與支柱21。在上 述連桿24A、24B連結喷嘴附設管16A、16B。 藉上述4根之連桿24A〜25B的作動，喷嘴附設管16A、 16B，係如第2圖所示，由垂直方向之實線位置到點線所 示之水平方向位置被以90度開關。亦即，橫轴22對於支柱 21位於最下點位置時，喷嘴附設管形成垂直方向，使其朝 上方移動後左右打開，到達最上點位置後形成水平位置。 另外，將連結支柱21與連桿25A、25B之栓26的位置 作成可以上下動，藉此，可以調節喷嘴附設管16A、16B 的高度。 如此，由於可以調節安裝喷霧藥液喷嘴17之喷嘴附 設管16A、16B之開關及高度，所以可以因應作物的高度 14 五、發明說明（l2) 調節位置，使其可以由最適當位置將藥液喷霧製作物。 在由上述之構造所形成之藥液喷霧車，首先，在行 走時’由於2輪之具有空氣之輪胎作為前輪，並鄰接配置 於車體2之寬方向之中央位置，所以2輪邊作為行走車輪， 不用擴大車寬，邊可以使其自由行走於故間之狹小境間。 而且，由於為2輪車，所以可以解除因1輪車有問題而無法 取得左右平衡之問題，並可以實現行走路面即使凹凸不平 亦可以一面取得左右的平衡一面安定的行走。 更進一步，由於作成可以使2輪獨立的旋轉，所以可 以仔到非常小的曲率，在寬度狹小之田故之埂間可以容易 的進行方向旋轉。 另外，為了刮落附著於行走車輪的外周面之泥土與 泥砂，由於使用多數之栓14 ,所以在刮落泥土與泥砂時可 以減少附加於刮土器的負荷。特別是，由於將栓14之載面 形狀作成向圓周方向較長之橢圓形狀，所以被負荷於栓14 之負重可以更小，同時由於作成鋸齒形配置，所以栓14被 脫離接觸於泥土與泥砂的位置，進一步可以減少加於栓14 之負荷。使其行走於田畝之壟溝後大量的泥土附著於車輪 的外周面’但如上述，以栓14作為刮土器，且由於固定於 車體2所以·強度也較大，進一步，由於為橢圓狀、作成鋸 齒形配置，所以可以確實的刮落附著於車輪的外周面之大 量之泥土與泥砂。 另一方面’即使關於由藥液箱8吸出藥液9，在藥液 箱8的底面8a，藉傾斜的設置，藥液9最終形成滯留於上述 15 491733V. Description of the invention (2) Considerable force, the burden on the operator when operating the handle becomes greater. In addition, in the medicinal solution spraying vehicle described in JP-A-3,296,458 and Shikoku Fair No.7-55909, the outer peripheral surface of the medicinal solution tank, which is slightly circular when viewed from the side, forms a structure covering the wheels, which has a complicated structure. Not only the manufacturing cost is relatively the same, because the side part is still not stable, so it has the problem of so-called difficulty in achieving balance when moving. In the cases of the spreaders described in Shiko Sho 63-27804, Shiko-Eki 3-1084, and Shiko-Eki 4-41960, since the medicine tank is placed on the wheels, the center of gravity is unstable. It is difficult to operate, the structure is more complicated, and the manufacturing cost becomes higher. As in the spreading machine described in Kankai Fair No. 4-41960, when a structure is provided with a foot for stationary at the rear, since it is wider than the wheel width, there is a so-called unstoppable sprayer in a small place such as an acre. problem. In addition to the above-mentioned problems, in the medicinal liquid spraying vehicle, it is necessary to use up the medicinal liquid supplied to the medicinal liquid tank installed in the car body without remaining, but the conventional medicinal liquid tank should be completely free of residual liquid. But it has its difficulties. That is, ‘hang the straw in the liquid medicine tank, and place the suction port at the end of the straw toward the bottom of the tank, or place the end diagonally on the bottom of the tank so that the liquid is attracted by the pump. If this structure is used, it will be difficult to attract to the end when the residual liquid becomes small, and the air will enter the straw due to the tilt of the tank and the shaking of the liquid. It may cause the pump to become unattractive and the medicine in the tank The residual amount of the liquid increases. In this way, after the remaining amount of the medicinal solution is increased, the cleaning of the box will not only take time, the remaining echinacea will be mixed with other pesticides used next time, so it will cause problems to the crop. Furthermore, because the suction tube is placed on the bottom surface of the box in the box, the inclination and vibration of the pump, and the end of the suction tube sucking on the bottom surface and side of the box due to the suction pressure of the suction tube may cause water absorption. The more progress is to make the dirt of the liquid spray mist truck ’s dirt that is walking on the hard ground of the farming field very easy to attach to the wheels, so it is necessary to scrape off the attached dirt and mud. As shown in Nos. 10A and 10B, the long iron plate A and the round rod B are arranged in parallel with the rotation axis Wa of the wheel%, and are used to scrape off the dirt and sand. Scraper. However, in a scraper formed by an iron plate and a round rod arranged in parallel to the above-mentioned rotation axis, when the dirt and sand adhered to the wheels increase, the scraper has a considerable load, so the scraper is damaged. Problem. Furthermore, in a chemical liquid spraying vehicle, a general operator holds a hose connected to a chemical liquid tank, and sprays the chemical liquid from a nozzle installed at the end of the hose. For this reason, it is necessary for the operator to walk the medicinal solution spray truck with hand pressure while holding the hose to disperse the medicinal solution. The medicinal solution stored in the box due to the large capacity of the box will make the car heavy. In this case, the burden on the operator is also increased. In addition, when it is necessary to spray the liquid medicine on the crops on the south side of the field, after spraying the liquid medicine on the crops on the side of the field, it is necessary to spray the liquid on the mu on the other side. The problem with the workload. The present invention aims to provide a medicinal liquid sprayer which can solve the problems listed above and is convenient to use. V. Description of the invention (4) <Means for solving the problem> In order to solve the above-mentioned problem, the present invention is to provide a medicinal liquid spraying vehicle including a vehicle body and a medicinal liquid tank; a power mist spraying device, It is mounted on the vehicle body; a hand-pressed handle is attached to the vehicle body; and, a traveling wheel is mounted on the vehicle body; and the traveling wheel is mounted on a shaft frame between two side plates of the vehicle body Install two tires on the axle of the root to adjoin the vacated spaces, and install these two wheels of tires on the axles so that they can rotate freely. Each tire can be made to rotate independently and independently. . Specifically, a pair of left and right wheel thrusting parts are protruded in the front part of the vehicle body, and the axle is fixed between the wheel support parts. On the axle, the same diameter can be freely rotated by gears. 2 tires with air. With this structure, it is arranged at the center in the width direction of the body of the two-wheel traveling wheel. The above-mentioned car system is integrally formed by blow molding, and the width of the car body is made to be able to walk between fields. The wheel support of the axle of the traveling wheel is fixed so that it does not protrude from the left and right outer side surfaces of the approximately linear body. This structure is constructed so that two wheels can be used as traveling wheels to walk freely between small fields and small acres. In addition, the above-mentioned vehicle body medicine tank is also integrally formed. In the present invention, as described above, since two wheels arranged adjacently are installed in the center of the width of the vehicle, the width of the vehicle cannot be enlarged, so that it can walk between narrow fields. In addition, since it is a two-wheeled vehicle, it is possible to solve the problem that it is difficult to achieve left-right balance due to the one-wheeled vehicle, and it is possible to achieve a stable walking while taking the balance of the fifth aspect of the invention (5). Furthermore, since two independent rotations can be made, a very small radius of rotation can be formed, and it can be easily rotated in a narrow field. The two-wheel tires are mounted on the front or / and the rear of the vehicle body. In other words, even if two wheels are installed at the front and rear of the vehicle body, even one of them can be used. In this case, it is better to install one caster. However, one caster is not installed, and the bottom of the car body is grounded in a circular arc shape. The present invention also provides a medicinal liquid spray vehicle in the second aspect, which includes: a car body, which is provided with a medicinal liquid tank; a power spray The fog device is mounted on the vehicle body; the hand-pressed handle is attached to the vehicle body; and the traveling wheel is installed on the vehicle body; and in order to scrape off the dirt and the outer surface attached to the traveling wheel, Mud sand has a large number of bolts protruding from the bottom surface of the vehicle body corresponding to the upper portion of the traveling wheels, as a scraper. As mentioned above, the conventional system uses rods and plates extending parallel to the axle as the soiling device. However, in the present invention, since a large number of bolts are used, the load on the soiling device can be reduced when the soil and sand are scraped off. Moreover, since the bolt of the scraper is integrally formed with the vehicle body or fixed to the vehicle body, the strength of the bolt can be increased. As a result, even if a large amount of dirt and sand adhere to the outer peripheral surface of the wheel, it can be scraped off by the scraper. . In particular, it is preferable that the cross-sectional shape of the bolt of the above-mentioned scraper is an ellipse shape which is longer in the circumferential direction of the wheel. In this way, after making a long oval shape in the circumferential direction, the load on the plug can be smaller, and at the same time, the longer the circumferential direction can improve the effect of scraping. V. Description of the invention (6) Further, the zigzag configuration (that is, the space is arranged in the axis direction and the space is arranged in the circumferential direction) after the bolts of the scraper are staggered, the bolts are staggered from the time of contact with the soil and sand. The load on the bolt can be reduced even more. The ratio of the bolt of the scraper to the wheel is preferably about 20%.

Because the nozzles are attached to the nozzles to provide space for the nozzles to be installed at intervals, the liquid medicine sprayer can be used to distribute the liquid medicine to most of the crops on the left and right sides. In addition, by adjusting the inclination angle (opening angle to the left and right) of the nozzle and the attached tube, the height of the attached tube can be adjusted according to the height of the crop. Moreover, it is needless to say that the operator may choose to replace the nozzle attachment tube provided at the end of the hose being held. The structure in which the operator holds the hose and uses the nozzle to distribute the medicinal solution may also be < the embodiment of the invention > An embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows the whole of the medicinal liquid spraying vehicle 1 of the present invention, 2 is a vehicle body integrally formed by blow molding, 3 (3A, 3B) is a tire having air on two wheels forming a front wheel, and 4 is forming a rear wheel One of the traveling wheels, 5 is a handle installed at the rear of the vehicle body 2, 6 is a chemical liquid spray nozzle device installed at the front of the vehicle body 2, and 7 (7A, 7B) is a chemical liquid supply hose. A medicinal solution tank is formed at the center of the above-mentioned vehicle 2. At the same time, a motor n for driving a pump is mounted on the rear of the vehicle body 2. The pump 10 is used to suck the medicinal solution in the medicinal solution tank 8. Remove the upper cover from the medicinal solution tank 8 and put in the pesticide and water. As shown in Fig. 2 and Fig. 3, the tires with air for two wheels have the same diameter as the narrow width. One axle 13 is fixed between a pair of left and right wrist-shaped wheel support portions 2a and 2b protruding from the front portion of the vehicle body 2. On the axle 13, the tires 3A and 3B are adjacent to each other without a gap. The gears are independently mounted for free rotation via gears. The vehicle width of the vehicle body 2 is made to be able to walk in the width of the ditch and the ditch. The above-mentioned wheel support portions 2a and 2b do not protrude outward from the side panels 仏 and 2d of the vehicle body 2, but protrude in a straight line. Thus, the two tires 3A and 3B forming the front wheel can be stored in the vehicle width w of the vehicle body 2. 491733 V. Description of the invention (9) The rear wheel 4, as shown in Figure 3, is formed by a small wheel of one wheel. It has a smaller diameter than the front wheel and can effectively make small rotations. It is made of resin drum or metal. A structure in which rubber is mounted on the outer peripheral surface of the drum. The support shaft 4a of the rear wheel 4 is rotatably supported by a bearing portion provided below the rear end of the vehicle body 2. The lower ends of the left and right vertical frame portions of the longitudinally r-shaped handle 5 are fixed to the left and right bearing portions, and the directional operation of the handle 5 is transmitted to the rear wheel 4. As shown in Figs. 5A, B, and C, a gap is obtained between the bottom surface 2e of the above-mentioned vehicle body 2 (front bottom side surface of the medicine tank 8) facing the outer periphery of the tires 3A and 3B, and the vehicle body 2 protrudes. The plurality of bolts 14 serve as scrapers for scraping off the mud and sand and soil attached to the two front wheels formed by the tires 3A and 3B. The above-mentioned scraper bolt 14 is formed in a long ellipse shape in the circumferential direction of the wheel, and is arranged in a zigzag manner with a space between the axial direction and the circumferential direction. In this embodiment, a total of four bolts are arranged, and two bolts of one tire are positioned in a circumferential direction at the 14th position so as to contact the sand and the like attached to the outer peripheral surface of the wheel. The ratio of these bolts 14 to the width of the wheel is about 20%. The medicinal liquid tank 8 provided with the vehicle body 2 as a body is provided in the central area of the vehicle body except for the power source mounting portion at the rear of the vehicle body, which is provided by the front end of the axle support portions 2a and 2b. The body 2 is miniaturized and the capacity of the medicinal solution tank 8 is increased. After the medicinal solution 9 is filled in the medicinal solution tank 8, the medicinal solution enters below the axles of the wheels 3 and 4, so that the center of gravity of the car body can be set to a very low position, thereby enabling stable walking. As shown in Figs. 6A, B, and C, a pair of residual liquid preventing ribs 8b and 8b are protruded opposite to the central portion of the bottom surface 8a, and are held by these ribs 8b and 12 49.1733. V. Invention Explanation (ίο) The center of the bottom surface 8a of 8b is formed as a spherical concave portion 8d which becomes the lowermost point. In this embodiment, the diameter of the recessed portion 8d is 30 mm to 80 mm, preferably 50 mm to 60 mm, and the depth is 10 mm to 30 mm, and preferably 20 mm to 25 mm, so that it can slip through the required amount of the chemical solution. A U-shaped suction pipe holding groove 8e is formed on the peripheral edge of the recessed portion 8d at the lowermost point, and has a recessed opening surface. The pipette holding groove 8e is fitted in the vicinity of the end of the medicinal solution suction pipe 15, and the end suction opening i5a of the medicinal solution suction pipe 15 is opened to the inside of the recessed portion 8d. In this state, the end suction port 15a is kept floating in the recessed portion 8d to prevent the end of the medicinal solution suction pipe 5 from being adsorbed on the bottom surface. The medicinal solution suction pipe 15 is connected to the suction port of the pump 10, and the medicinal solution in the recessed portion 8d is sucked to the last drop by the action setting of the pump 10. As shown in FIG. 6D, the above-mentioned pair of ribs 8b are provided with gaps and protrusions. The ribs are provided with openings 8f that are not covered, and face the openings 8f, so that the bottom surface 8a of the medicine tank 8 is inclined downward. With this structure, the medicinal solution 9 in the medicinal solution tank 8 flows down to the space held in the rib 8b, and finally remains in the recess 8d. The medicinal solution 9 in the medicinal solution tank 8 is borrowed from the medicinal solution suction pipe 15 to make no Residual fluid is attracted to the structure. As the power spray device mounted on the vehicle body 2, the aforementioned pump 10 and the engine 11 for driving the pump are mounted on the rear of the vehicle body. As shown in Figs. 1 and 2, the suction port of the pump 10 is connected to the medicinal solution suction pipe 15 as described above, and two hoses 7A and 7B are connected to the discharge pipe 19 connected to the discharge port as described above. These two hoses 7A, 7B are piping on the upper side of the car body 2 toward the rear, and are respectively connected to the nozzle attachment pipe 16 (16A) of the medical liquid spray nozzle device 6 attached to the front of the car body 2 , 16B). 13 491733 V. Description of the invention (11) Tubes 16A and 16B are attached to each nozzle, which can be used to spray the medicinal solution to a large number of acres. (In this embodiment, one nozzle can be sprayed with 3 tubes, so 'total 6 acres') The length of the crop is such that a large number of nozzles 17 are installed at intervals (three in this embodiment). These nozzles π can be used to stop the injection by rotating the nozzle, and use the nozzle whose direction can be adjusted. The chemical liquid spray nozzle device 6, or the above-mentioned left and right pair of nozzle attachment pipes 16A, 16B, is made to be able to adjust the height and the opening angle by a link-type lifting and lowering switch mechanism 20 fixed on the vehicle body 2. In other words, the lifting and switching mechanism 20 is formed by the pillar 21, the horizontal axis 22, the links 24A, 24B, and the links 25A, 25B. The horizontal axis 22 can be freely raised and lowered and embedded in the pillar 21 at the center; the links 24A and 24B are freely rotating shafts at both ends of the horizontal axis 22; the links 25A and 25B are connected by bolts 26 connects the other ends of these connecting rods 24A, 24B with the pillar 21. The nozzle attachment pipes 16A and 16B are connected to the connecting rods 24A and 24B. By the operation of the above-mentioned four connecting rods 24A to 25B, the nozzles are provided with tubes 16A and 16B. As shown in Fig. 2, the position from the solid line in the vertical direction to the horizontal position shown by the dotted line is switched at 90 degrees. That is, when the horizontal axis 22 is located at the lowermost point position with respect to the pillar 21, the nozzle attachment pipe forms a vertical direction, moves it upward, opens left and right, and reaches a horizontal position after reaching the uppermost point position. In addition, the positions of the bolts 26 connecting the pillars 21 and the connecting rods 25A and 25B can be moved up and down, whereby the heights of the nozzle attachment pipes 16A and 16B can be adjusted. In this way, since the switches and heights of the nozzle attachment pipes 16A and 16B of the spraying liquid medicine nozzle 17 can be adjusted, the height of the crop can be adjusted. 14 V. Description of the invention (l2) Adjust the position so that the medicine can be adjusted from the most appropriate position. Liquid spray preparation. In the medicinal liquid spray vehicle formed by the above structure, first, when traveling, 'the two wheels with air are used as the front wheels, and are arranged adjacent to the center position in the width direction of the vehicle body 2. The walking wheels do not need to widen the width of the car, so that they can walk freely in the narrow space of the home. In addition, since it is a two-wheeled vehicle, it is possible to solve the problem that the left-right balance cannot be obtained due to the problem of the one-wheeled vehicle, and it is possible to achieve stable walking while maintaining the right and left balance even when the road surface is uneven. Furthermore, since it can be made to rotate independently with two wheels, it can be made to a very small curvature, and can be easily rotated in the direction of a narrow field. In addition, in order to scrape off the dirt and mud adhering to the outer peripheral surface of the traveling wheel, since a large number of bolts 14 are used, the load attached to the scraper can be reduced when scraping the dirt and mud. In particular, since the shape of the load-bearing surface of the bolt 14 is made into an ellipse shape that is longer in the circumferential direction, the load on the bolt 14 can be smaller, and at the same time, because of the zigzag configuration, the bolt 14 is released from contact with the soil and mud The position can further reduce the load imposed on the bolt 14. A large amount of dirt adheres to the outer surface of the wheel after walking on the ditch of the acre. As described above, the bolt 14 is used as a scraper and it is fixed to the vehicle body 2. Therefore, the strength is also strong. Furthermore, because it is oval, The zigzag arrangement makes it possible to reliably scrape off a large amount of dirt and sand adhered to the outer peripheral surface of the wheel. On the other hand, even if the medicinal solution 9 is sucked out from the medicinal solution tank 8, the medicinal solution 9 finally forms and stays in the above-mentioned 15 491733 on the bottom surface 8a of the medicinal solution tank 8.

Description of the invention (13) Concave portion 8d. As for the recessed portion 8d, since the end suction port 15a of the medicinal solution straw 15 held by the opening of the straw holding groove 8e is held, the residual liquid in the medicinal solution tank 8 does not remain, and the medicinal solution straw 5 can be sucked into completely. In particular, the water suction opening i5a at the end of the medicinal solution suction tube 15 floats in the recessed portion 8d. Since the bottom and sides of the medicinal solution tank 8 are not contacted, it can be prevented from being adsorbed on the bottom and sides, and will not become non-absorbent. The spraying operation is not interrupted, and damage to the medicine tank 8 can be prevented. In addition, in order to provide the rib portion 8b so as to surround the recessed portion 8d, even if the vehicle body is tilted, the liquid medicine in the rib portion 8b can be prevented from flying out, the liquid medicine stays in the rib portion 8b, and finally can stay in the recessed portion 8d. In this way, since there is no residual liquid, cleaning of the medicinal solution tank 8 becomes easy, and it is possible to prevent mixing with the pesticide to be used next time and to cause the medicinal solution to be distributed to cause damage to crops. The medicinal solution 9 which is attracted by the pump through the pump and is discharged at a desired pressure is guided to the nozzle injection device 6 at the front of the vehicle body 2 through the hoses 7A and 7B, The nozzles 17 attached to the nozzle attachment pipes 16A and 16B are sprayed. Since each nozzle 17 is installed on the nozzle attachment pipes 16A and 16B at intervals to make it correspond to the interval of the respective acres, the liquid medicine sprayer can be used to distribute the liquid medicine to most of the left and right acres at the same time. Crop. In addition, the inclination angle of the nozzle attachment tube 16 can be adjusted as described in the above-mentioned left-right direction switch operation nozzle (the angle toward the left and right), and the height can also be adjusted, so the nozzle attachment tube 16 (16A, 16B), spray the liquid medicine to the crop from the most appropriate position. 16 V.

As shown in FIG. 7, a nozzle attachment pipe 16 is provided at the end of the hose 30 held by the operator, and the selected replacement is connected to the helper. It is also possible to use the piping at Putu outlet. In this case, by using the liquid medicine spray nozzle device instead of the automatic liquid medicine spray, the operator can use a hose to distribute the liquid medicine to only the crops needed. In addition, as shown in Fig. 8, the scraper 14 for scraping off the sand and soil adhering to the wheel may be formed by a protrusion provided integrally with the body 2 of the vehicle. In addition, the plug 14 formed by the protrusion can be made into a circular projecting shape with a cylindrical shape, and it can be arranged so that the space is in contact with the axis direction of the wheel at intervals. It is not necessary to be mineralized as in the aforementioned embodiment. Toothed configuration. Furthermore, the mounting type of the traveling wheels is not limited to the above-mentioned implementation type. As shown in FIG. 9, the rear wheel 4 may be a two-wheeled vehicle formed of the same tires as the front wheel 3. In this case, it is best to make trails for the rear wheels. Furthermore, as shown in FIG. 9B, even if the front wheel 3 is made! It is also possible to make the rear wheel into two wheels. Further, as shown in FIG. 9C, the front wheel 3 is made into a two-wheeled vehicle, and the rear wheels are not provided with casters, and an arc-shaped portion 2g 'may be provided at the bottom of the vehicle body 2 to ground it. < Effects of the invention > From the above description, it can be understood that if the medicinal liquid spray vehicle according to the present invention is used as a rod wheel, as a front wheel or / and a rear wheel, since two tires with air of the same diameter are borrowed, The gear is installed to be able to rotate freely, and two wheels are used as traveling wheels.

Description of the invention (15) Since the two wheels are made to rotate independently, it becomes a very small radius of rotation when rotating in the direction. Therefore, the ditch in a narrow acre can be easily rotated in the direction. Furthermore, a large amount of sand is attached to the traveling wheel, but at a position contacting the outer peripheral surface of the wheel, a plurality of bolts formed integrally with the vehicle body and / or fixed to the vehicle body are protruded from the bottom surface of the vehicle body at intervals. Since this inspection is used as a scraper, all the dirt and mud adhering to the outer peripheral surface of the wheel can be reliably scraped off. Furthermore, in addition, a pair of ribs are protruded on the bottom surface of the medicinal solution tank, and a concave portion forming a lowermost point is provided at a slightly center of the bottom surface held by the ribs, and at the same time, a portion of the periphery of the concave portion is provided. An opening straw holding groove is inserted into the straw holding groove at the end of the medicinal liquid straw. Since the water suction opening at the end of the medicinal liquid straw is opened to the inside of the recessed portion, the residual liquid in the medicinal liquid tank will not remain. You can inhale the medicinal solution straw slightly. In addition, it is possible to prevent suction on the bottom and side surfaces, to prevent water from being absorbed, to prevent the spraying of the chemical solution from being interrupted, and to prevent damage to the chemical solution tank. Furthermore, as the spraying mechanism of the medicinal liquid, since the medicinal liquid spraying nozzle device is attached, the nozzle attachment tube can be switched on and off, and the height can be adjusted, so that the height of the nozzle attachment tube can be adjusted according to the height of the crop and growth conditions. The liquid medicine can be sprayed from the most appropriate position. In addition, the medicinal solution can be automatically sprayed to crops of many acres. Since the operator only needs to press the medicinal solution sprayer by hand, the burden on the operator can be greatly reduced. <Brief Description of Drawings> Fig. 1 is a diagram showing the overall implementation of the medicinal liquid spray truck of the present invention 49,1733
