Description

本発明は、ゴルフ場，公園，競技場などの芝の育成管理をするのに使用するもので、平米当たりの散布量を一定に保って散布できる定量散布車に関するものである。   The present invention is used for turf cultivation management in golf courses, parks, stadiums, and the like, and relates to a quantitative spraying vehicle capable of spraying while maintaining a constant spraying amount per square meter.

従来のこの種の定量散布車（装置）として例えば特開平６−１１４３０７号公報に示されるものがあり、これは散布車の走行速度及びノズル部の圧力を検出してマイコンで演算し、サーボバルブを制御して走行速度に応じた散布を行うものである。
特開平６−１１４３０７号公報 For example, Japanese Patent Application Laid-Open No. 6-114307 discloses a conventional quantitative spraying vehicle (apparatus) of this type, which detects the traveling speed of the spraying vehicle and the pressure of the nozzle portion and calculates it by a microcomputer. Is controlled to perform spraying according to the traveling speed.
JP-A-6-114307

解決しようとする問題は、前記した従来のもののように走行速度及びノズル部の圧力をセンサーによって検出してその流量をサーボバルブによって制御すると、散布域が比較的平坦なところでは走行速度をほぼ一定に維持できるので予め定めた流量で散布していれば問題はないが、アップダウンのある起伏の多い散布域では走行速度が激しく変化するためそれに応じて流量を変化させなければならないので、その走行速度及び圧力の検出カウントが短すぎるとサーボバルブの応答が過敏となってその結果流量が大きく波打つようになるし，逆に検出カウントが長すぎるとサーボバルブの応答性が悪くなり、全体として平米当たりの散布量が一定にならないという点である。   The problem to be solved is that when the traveling speed and nozzle pressure are detected by a sensor and the flow rate is controlled by a servo valve as in the conventional case described above, the traveling speed is almost constant when the spray area is relatively flat. If it is sprayed at a predetermined flow rate, there is no problem, but since the traveling speed changes drastically in the up and down undulating spraying region, the flow rate must be changed accordingly, so that traveling If the detection count of speed and pressure is too short, the response of the servo valve will be too sensitive, and as a result, the flow rate will be greatly undulated. The amount of spraying per hit is not constant.

請求項１の発明は、薬液タンクと、この薬液タンクより薬液を散布するポンプと、このポンプからの薬液を噴出するノズルとを台車に備えたものであって、前記ポンプは散布時に定速回転しその上で前記台車が走行したときにその車輪の回転と連動して駆動回転されるようにしたことを特徴とする。   The invention according to claim 1 is provided with a chemical tank, a pump for spraying the chemical liquid from the chemical tank, and a nozzle for ejecting the chemical liquid from the pump. The pump rotates at a constant speed when spraying. In addition, when the carriage travels, it is driven and rotated in conjunction with the rotation of its wheels.

請求項２の発明は、請求項１の発明においてそのポンプとノズルの間にアンロード弁を備えた三方弁式のバイパスバルブを設けたことを特徴とする。   The invention of claim 2 is characterized in that in the invention of claim 1, a three-way valve type bypass valve provided with an unload valve is provided between the pump and the nozzle.

請求項３の発明は、薬液タンクと、この薬液タンクより薬液を散布するポンプと、このポンプからの薬液を噴出するノズルとを台車に備えたものであって、前記ポンプとノズルの間にアンロード弁を備えた三方弁式のバイパスバルブを設けたことを特徴とする。   According to a third aspect of the present invention, a cart includes a chemical liquid tank, a pump for spraying the chemical liquid from the chemical liquid tank, and a nozzle for ejecting the chemical liquid from the pump. A three-way valve type bypass valve provided with a load valve is provided.

請求項１の発明は、台車の車輪の回転と連動してポンプが駆動回転されることにより、走行速度に応じた平米当たりの散布量が得られるので、例えばアップダウン地の如く走行速度が激しく変化する散布域でもその流量変化がデジタル的な変化でなく，アナログ的な変化となって滑らかになり、平米当たりの散布量を一定に保って散布できるという効果がある。   In the first aspect of the invention, since the pump is driven and rotated in conjunction with the rotation of the wheels of the carriage, a spraying amount per square meter according to the traveling speed can be obtained. Even in the changing spraying area, the change in flow rate is not a digital change, but an analog change that is smooth and the spraying amount per square meter can be kept constant.

請求項２の発明は、請求項１の発明においてそのポンプとノズルの間にアンロード弁を備えた三方弁式のバイパスバルブを設けることにより、走行速度に関係なく散布量に適した散布圧力が得られるので、例えばアップダウン地の如く走行速度が激しく変化する散布域でも平米当たりの散布量を一定に保って散布できると共に、アンロード弁付きバイパスバルブによってノズルの噴管が複数本ある場合にその一本を止めても残りの噴管のノズルからは散布量に適した散布圧力が得られるので、例えば散布域で残りの散布エリアが狭くなったり，バンカー廻りなど急に散布エリアが狭くなって、散布域のオーバーラップを避けるために噴管の数を減らした場合でも、平米当たりの散布量を一定に保って散布できるという効果がある。   The invention of claim 2 provides a spraying pressure suitable for the spraying amount regardless of the traveling speed by providing a three-way valve type bypass valve having an unloading valve between the pump and the nozzle in the invention of claim 1. As a result, for example, even in areas where the traveling speed changes drastically, such as in up-down areas, it is possible to spray with a constant spray rate per square meter, and when there are multiple nozzle nozzles with a bypass valve with an unload valve Even if one of them is stopped, the remaining spray nozzles can provide a spraying pressure suitable for the amount of spraying. For example, the remaining spraying area becomes narrow in the spraying area, or the spraying area suddenly narrows around the bunker. Thus, even when the number of nozzles is reduced in order to avoid the overlap of the spraying areas, it is possible to spray with a constant spraying amount per square meter.

請求項３の発明は、アンロード弁付きバイパスバルブによってノズルの噴管が複数本ある場合にその一本を止めても残りの噴管のノズルからは散布量に適した散布圧力が得られるので、競技場やゴルフ場のグリーンの如く平坦地で一定の走行速度で使用できる場合に、例えば散布域で残りの散布エリアが狭くなったり，バンカー廻りなど急に散布エリアが狭くなって、散布域のオーバーラップを避けるために噴管の数を減らした場合でも、平米当たりの散布量を一定に保って散布できるという効果がある。   According to the third aspect of the present invention, when there are a plurality of nozzle nozzle tubes by a bypass valve with an unload valve, even if one of them is stopped, a spraying pressure suitable for the spraying amount can be obtained from the nozzles of the remaining nozzle tubes. When it can be used at a constant traveling speed on a flat surface such as a stadium or golf course green, for example, the remaining spray area becomes narrow in the spray area, or the spray area suddenly becomes narrow, such as around the bunker. Even if the number of tubes is reduced in order to avoid overlap, there is an effect that the amount of spraying per square meter can be kept constant.

ポンプとノズルの間にアンロード弁を備えた三方弁式のバイパスバルブを設けることにより、実現した。   This was realized by providing a three-way valve bypass valve with an unload valve between the pump and nozzle.

請求項１の発明の一実施例を図１〜図３を用いて説明する。
図１は定量散布車を示す側面図、図２は図１を上からみた平面図、図３は図１の定量散布車の配管系統図である。 An embodiment of the invention of claim 1 will be described with reference to FIGS.
FIG. 1 is a side view showing a quantitative spreader, FIG. 2 is a plan view of FIG. 1 as viewed from above, and FIG. 3 is a piping diagram of the quantitative spreader in FIG.

図において、１は定量散布車の台車、２は台車１に搭載したエンジン、３はエンジン２により駆動される油圧式可変ポンプ、４は台車１の車輪、５は車輪４を駆動するデフ付き変速機、６はデフ付き変速機５に取り付けた油圧モータ、７は台車１に搭載した薬液タンク、８はデフ付き変速機５に設けられて薬液タンク７からの薬液を散布するポンプ、９はポンプ８からの薬液を噴出するノズル、１０はノズル９とポンプ８の間に設けた手動三方コックで、三口目に配管１１を設けてポンプ８よりの薬液を薬液タンク７側に戻せるようにしている。   In the figure, reference numeral 1 is a truck of a fixed spreader, 2 is an engine mounted on the truck 1, 3 is a hydraulic variable pump driven by the engine 2, 4 is a wheel of the truck 1, and 5 is a geared shift gear that drives the wheel 4. , 6 is a hydraulic motor attached to the differential-equipped transmission 5, 7 is a chemical tank mounted on the carriage 1, 8 is a pump that is provided in the differential-equipped transmission 5 and sprays chemical liquid from the chemical tank 7, and 9 is a pump Nozzle 8 for ejecting the chemical solution 10 is a manual three-way cock provided between the nozzle 9 and the pump 8, and a pipe 11 is provided at the third port so that the chemical solution from the pump 8 can be returned to the chemical solution tank 7 side. .

なお、図中１２はポンプ８より吐出した薬液の一部を逃がすための逃がしバルブで、手動三方コック１０への総流量を決定するものである。また、図中１３はポンプ８からの散布圧力を計測するための圧力計である。   In the figure, reference numeral 12 denotes a relief valve for releasing a part of the chemical liquid discharged from the pump 8, and determines the total flow rate to the manual three-way cock 10. In the figure, reference numeral 13 denotes a pressure gauge for measuring the spray pressure from the pump 8.

油圧ポンプ３と油圧モータ６は、図示しないが油圧ホースで接続されて閉回路が構成され、いわゆるＨ．Ｓ．Ｔ回路となっている。よって、エンジン２の駆動により車輪４を回転させて台車１を前後進させる。また、油圧ポンプ３には、図示しないが油圧油量を変化させる斜板を段階的に規制するストッパー機構があり、斜板の傾転角度を段階的に変化させることによって作業速度を例えば６ｋｍ／Ｈ，８ｋｍ／Ｈ，１０ｋｍ／Ｈのように段階的に選定できるようになっている。   Although not shown, the hydraulic pump 3 and the hydraulic motor 6 are connected by a hydraulic hose to form a closed circuit. S. It is a T circuit. Therefore, the wheel 4 is rotated by driving the engine 2 to move the cart 1 forward and backward. The hydraulic pump 3 has a stopper mechanism that regulates the swash plate that changes the hydraulic oil amount in a stepwise manner (not shown). By changing the tilt angle of the swash plate in a stepwise manner, the working speed is reduced to, for example, 6 km / It can be selected in stages such as H, 8 km / H, and 10 km / H.

デフ付き変速機５は、走行時と作業時の二段の切換えができるもので、作業時にのみ車輪４の回転と同調するようにポンプ８が連動されると共に、作業時の停止時（車輪４が回らないとき）には中立位置にあってこの状態では油圧モータ６の回転を作業時と同等の回転がポンプ８に伝達されることにより、台車１の停止状態でもポンプ８を定速回転させるようになっている。   The differential-equipped transmission 5 can be switched between two stages during traveling and during operation. The pump 8 is interlocked so as to synchronize with the rotation of the wheel 4 only during operation, and when the transmission is stopped (wheel 4 In this state, the rotation of the hydraulic motor 6 is transmitted to the pump 8 at the same time as the operation, so that the pump 8 is rotated at a constant speed even when the carriage 1 is stopped. It is like that.

次に動作について説明する。
エンジン２を駆動してデフ付き変速機５を走行時に切換えると、エンジン２により駆動回転される油圧ポンプ３及びこの油圧ポンプ３よりの油量により駆動回転される油圧モータ６により、デフ付き変速機５を介して車輪４が回転されて台車１が前後進する。 Next, the operation will be described.
When the engine 2 is driven and the transmission 5 with differential is switched during travel, the transmission with differential is driven by a hydraulic pump 3 driven and rotated by the engine 2 and a hydraulic motor 6 driven and rotated by the amount of oil from the hydraulic pump 3. The wheel 4 is rotated via 5 and the carriage 1 moves forward and backward.

そして、デフ付き変速機５を作業時に切換えると、台車１が停止した状態では、油圧モータ６の回転がそのままポンプ８を駆動（定速）回転し、薬液タンク７の薬液がノズル９から散布される。この時ノズル９からの散布量が一定になるように予め設定しておく。   When the transmission with differential 5 is switched at the time of operation, when the carriage 1 is stopped, the rotation of the hydraulic motor 6 drives the pump 8 as it is (constant speed), and the chemical solution in the chemical solution tank 7 is sprayed from the nozzle 9. The At this time, the spraying amount from the nozzle 9 is set in advance so as to be constant.

即ち、エンジン２の回転を定回転としてＨ．Ｓ．Ｔ回路を構成する油圧ポンプ３の斜板をある位置で規制（斜板の傾転角度を固定）すれば作業速度は一定となる。こうして、段階的に選択できる作業速度を決め、平米当たりの散布量を決めると、これによってノズル９の数からノズル９への総水量が決まるから、その流量から散布圧力が決定される。   That is, when the rotation of the engine 2 is a constant rotation, the H.C. S. If the swash plate of the hydraulic pump 3 constituting the T circuit is restricted at a certain position (the tilt angle of the swash plate is fixed), the working speed becomes constant. Thus, when the work speed that can be selected in stages is determined and the spraying amount per square meter is determined, the total water amount to the nozzles 9 is determined from the number of nozzles 9, and the spraying pressure is determined from the flow rate.

こうして、台車１が走行すると、ポンプ８はデフ付き変速機５に連結されて車輪４の回転と同調して回転するので、走行速度に応じた平米当たりの散布量がノズル９から散布される。   Thus, when the carriage 1 travels, the pump 8 is connected to the differential transmission 5 and rotates in synchronism with the rotation of the wheels 4, so that the spraying amount per square meter corresponding to the traveling speed is sprayed from the nozzle 9.

即ち、まず、平米当たりの散布量と作業（走行）速度を決める。これによって、ノズル９の数からノズル９への総流量が決まる。
こうして、ノズル９からの総吐出量が決まると、その流量から散布圧力が決定されるので、手動三方コック１０をノズル９側に回してノズル９より散布し、このとき圧力計１３を見ながら逃がしバルブ１２の開閉によって配管内の圧力を散布圧力となるように調整する。こうすることによって、ポンプ８の吐出量は車輪４と連動して駆動されているから、走行速度に応じた平米当たりの散布量が得られることになる。 That is, first, the spraying amount per square meter and the work (running) speed are determined. Thus, the total flow rate to the nozzles 9 is determined from the number of the nozzles 9.
Thus, when the total discharge amount from the nozzle 9 is determined, the spraying pressure is determined from the flow rate, so the manual three-way cock 10 is sprinkled from the nozzle 9 and sprayed from the nozzle 9, and at this time, the pressure gauge 13 is seen to escape. The pressure in the pipe is adjusted to the spraying pressure by opening and closing the valve 12. By doing so, since the discharge amount of the pump 8 is driven in conjunction with the wheels 4, a spray amount per square meter corresponding to the traveling speed can be obtained.

例えば、ポンプ８と車輪４との関係は、走行速度６ｋｍ／Ｈで作業をした場合、ポンプ８の吐出量が１２０Ｌ／ｍｉｎとなるようにデフ付き変速機５で連結されており、また走行速度８ｋｍ／Ｈで作業をすると、この走行速度に連動してポンプ８の吐出量が１６０Ｌ／ｍｉｎとなるようになっている。   For example, the relationship between the pump 8 and the wheel 4 is that the pump 8 and the wheel 4 are connected by the differential-equipped transmission 5 so that the discharge amount of the pump 8 is 120 L / min when working at a traveling speed of 6 km / H. When the work is performed at 8 km / H, the discharge amount of the pump 8 is set to 160 L / min in conjunction with the traveling speed.

請求項２の発明の一実施例を図４，図５を用いて説明する。
図４は図３と同じ配管系統図、図５は図４のバイパスバルブを示す断面図で、図中前記した実施例１のものと同一または相当部分には同一符号を付して説明を省略する。 An embodiment of the invention of claim 2 will be described with reference to FIGS.
4 is the same piping system diagram as FIG. 3, FIG. 5 is a cross-sectional view showing the bypass valve of FIG. 4, and the same or corresponding parts in FIG. To do.

図において、１４はポンプ８とノズル９の間に設けたアンロード弁を備えた三方弁式のバイパスバルブで、３本の噴管１５ａ，１５ｂ，１５ｃへそれぞれ配設されるように３個のバルブ１４Ａ，１４Ｂ，１４Ｃの三連式のものを示している。なお、このバイパスバルブ１４は、必要に応じて中間のバルブ１４Ｂを無くしたり，その数を増やせるので、噴管数の増減が自在に行える。   In the figure, reference numeral 14 denotes a three-way valve type bypass valve provided with an unload valve provided between a pump 8 and a nozzle 9, and is provided with three pieces so as to be arranged in three injection pipes 15a, 15b and 15c, respectively. A triple type of valves 14A, 14B, and 14C is shown. Since the bypass valve 14 can eliminate or increase the number of intermediate valves 14B as necessary, the number of injection tubes can be freely increased or decreased.

このバイパスバルブ１４は、図示省略するが３個の三方弁閉子１４ａ，１４ｂ，１４ｃが電動モータによりそれぞれ回転するようになっており、これによってポンプ８からの薬液をノズル９側へ圧送したり，薬液タンク７側へ戻したりするようになっている。３個のアンロード弁１６ａ，１６ｂ，１６ｃは、つまみ１７ａ，１７ｂ，１７ｃを回すことによりそれぞれのバネによる付勢力を変化させ、バイパスバルブ１４内の圧力を一定に保つようになっている。   Although not shown, the bypass valve 14 has three three-way valve closures 14a, 14b, and 14c that are each rotated by an electric motor, whereby the chemical solution from the pump 8 is pumped to the nozzle 9 side. , And return to the chemical tank 7 side. The three unload valves 16a, 16b, and 16c change the urging force of each spring by turning the knobs 17a, 17b, and 17c, and keep the pressure in the bypass valve 14 constant.

次に動作について説明する。
エンジン２を駆動して、デフ付き変速機５を走行時に切換えると台車１が前後進し、デフ付き変速機５を作業時に切換えるとエンジン２の回転を定回転としてＨ．Ｓ．Ｔ回路を構成する油圧ポンプ３の斜板をある位置で規制（斜板の傾転角度を固定）すれば作業速度は一定となる。こうして、段階的に選択できる作業速度を決め、平米当たりの散布量を決めると、これによってノズル９の数からノズル９への総水量が決まるから、その流量から散布圧力が決定される。ここまでは前記した実施例１のものと同じである。 Next, the operation will be described.
When the engine 2 is driven and the transmission 5 with differential is switched during travel, the carriage 1 moves forward and backward, and when the transmission 5 with differential is switched during operation, the rotation of the engine 2 is set to a constant rotation. S. If the swash plate of the hydraulic pump 3 constituting the T circuit is restricted at a certain position (the tilt angle of the swash plate is fixed), the working speed becomes constant. Thus, when the work speed that can be selected in stages is determined and the spraying amount per square meter is determined, the total water amount to the nozzles 9 is determined from the number of nozzles 9, and the spraying pressure is determined from the flow rate. The steps so far are the same as those in the first embodiment.

こうして散布圧力が決定されると、バイパスバルブ１４の３個の三方弁閉子１４ａ，１４ｂ，１４ｃをノズル９側に回してノズル９より散布し、この時圧力計１３を見ながら逃がしバルブ１２の開閉によって配管内の圧力を散布圧力となるように調整すると、走行速度に応じた平米当たりの散布量がノズル９から得られる。   When the spraying pressure is determined in this way, the three three-way valve closures 14a, 14b, 14c of the bypass valve 14 are rotated toward the nozzle 9 and sprayed from the nozzle 9, and at this time, the relief valve 12 is When the pressure in the pipe is adjusted to become the spraying pressure by opening and closing, the spraying amount per square meter according to the traveling speed is obtained from the nozzle 9.

次いで、バイパスバルブ１４の一つバルブ１４Ｃを，その三方弁閉子１４ｃを回転させて薬液タンク７側へ回すと（図５の状態）、噴管１５ｃの流量分がバルブ通路内に増大して通路内の圧力が上昇するので、バルブ１４Ｃのつまみ１７ｃを回してバネ圧を散布圧力に等しくなるように弱めると、アンロード弁１６ｃが開いて先ほどの噴管１５ｃの一本分増大した流量が薬液タンク７へ戻ることになる。そして、バルブ１４Ｃを再度薬液タンク７側よりノズル９側へ回して、残りの二つのバルブ１４Ａ，１４Ｂを一つずつ同じ操作をする。そうすると、薬液タンク７側へ回したバルブからその散布量分だけ薬液タンク７へ戻ることになり、バイパスバルブ１４の通路内は常に一定の散布圧力に維持される。   Next, when one valve 14C of the bypass valve 14 is rotated toward the liquid chemical tank 7 by rotating the three-way valve closing member 14c (the state shown in FIG. 5), the flow rate of the injection tube 15c increases into the valve passage. Since the pressure in the passage rises, when the knob 17c of the valve 14C is turned to weaken the spring pressure so as to be equal to the spraying pressure, the unload valve 16c opens and the flow rate increased by one of the above-described jet tube 15c increases. Return to the chemical tank 7. Then, the valve 14C is turned again from the chemical tank 7 side to the nozzle 9 side, and the remaining two valves 14A and 14B are operated one by one. If it does so, it will return to the chemical | medical solution tank 7 from the valve | bulb rotated to the chemical | medical solution tank 7 side, and it will return to the chemical | medical solution tank 7 by the spraying quantity, and the inside of the channel | path of the bypass valve 14 is always maintained at a fixed spraying pressure.

即ち、以上のように３本の噴管１５ａ，１５ｂ，１５ｃのうちの一つの噴管１５ｃを散布中に止めても、残りの二つの噴管１５ａ，１５ｂは一定の散布圧力が維持できるので、例えば散布域で残りの散布エリアが狭くなったり，バンカー廻りなど急に散布エリアが狭くなって、散布域のオーバーラップを避けるために噴管の数を減らした場合でも、平米当たりの散布量を一定に保って散布できる。   That is, even if one of the three jet tubes 15a, 15b, 15c is stopped during spraying as described above, the remaining two jet tubes 15a, 15b can maintain a constant spray pressure. Even if, for example, the remaining spray area becomes narrow in the spray area, or the spray area suddenly becomes narrow, such as around a bunker, the number of spray pipes is reduced to avoid the overlap of the spray areas, the spray amount per square meter Can be sprayed while keeping constant.

請求項３の発明の一実施例を図６を用いて説明する。
図６は図４と同じ配管系統図で、図中前記した実施例２のものと同一または相当部分には同一符号を付して説明を省略する。 An embodiment of the invention of claim 3 will be described with reference to FIG.
FIG. 6 is the same piping system diagram as FIG. 4. In FIG. 6, the same or corresponding parts as those in the second embodiment are designated by the same reference numerals, and the description thereof is omitted.

本実施例は、ポンプ８をクラッチ１８を介してエンジン２により駆動する点で、前記実施例２とは異なる。このことにより、ポンプ８は常時定速回転してバイパスバルブ１４へ一定の流量が供給される。バイパスバルブ１４の構成，動作は前記実施例２のものと同じであるのでここでは説明を省略する。   The present embodiment is different from the second embodiment in that the pump 8 is driven by the engine 2 via the clutch 18. As a result, the pump 8 always rotates at a constant speed and a constant flow rate is supplied to the bypass valve 14. Since the configuration and operation of the bypass valve 14 are the same as those of the second embodiment, the description thereof is omitted here.

よって、本機の場合には、競技場やゴルフ場のグリーンの如く平坦地で一定の走行速度で使用できる場合に、例えば散布域で残りの散布エリアが狭くなったり，バンカー廻りなど急に散布エリアが狭くなって、散布域のオーバーラップを避けるために噴管の数を減らした場合でも、平米当たりの散布量を一定に保って散布できる。   Therefore, in the case of this machine, when it can be used at a constant traveling speed on a flat ground such as a green in a stadium or golf course, the remaining spray area becomes narrow in the spray area, or suddenly spread around the bunker, etc. Even when the area is narrowed and the number of nozzles is reduced in order to avoid overlapping of the spray areas, the spray volume per square meter can be kept constant.

本発明は、ゴルフ場，公園，競技場などで使用する定量散布車に広く活用できる。   The present invention can be widely used in a quantitative spray vehicle used in golf courses, parks, stadiums, and the like.
