そして、ブロアを駆動してタンク内を負圧にし、吸込管
の開閉弁を開き、吸込管より吸引物をタンク内に吸引
し、吸引物がある程度タンク内に入ると、排出配管の開
閉弁を開き、吸引物より分離した上水を排出配管より排
出する排水作業を吸引作業と同時に行い,排水作業が終
了すると排出配管の開閉弁を閉じて吸引作業のみを行っ
ていた。Then, the blower is driven to make the inside of the tank a negative pressure, the on-off valve of the suction pipe is opened, the suctioned substance is sucked into the tank from the suction pipe, and when the suctioned substance enters the tank to some extent, the on-off valve of the discharge pipe is opened. The drainage work of opening and discharging the clean water separated from the suctioned substances through the discharge pipe was performed at the same time as the suction work, and when the drainage work was completed, the on-off valve of the discharge pipe was closed and only the suction work was performed.
そしてまた排水作業が必要になると排出配管の開閉弁を
開いて排水作業と吸引作業とを同時に行っていた。When the drainage work is required again, the on-off valve of the discharge pipe is opened to perform the drainage work and the suction work at the same time.
(c)考案が解決しようとする課題 このため、排水作業を行うたびに排出配管の開閉弁を開
いたり、閉じたりしなければならず、作業が複雑になる
ばかりか、作業時間が長くなるという問題があった。(C) Problems to be solved by the invention For this reason, it is necessary to open and close the opening / closing valve of the discharge pipe each time the drainage work is performed, which not only complicates the work but also lengthens the work time. There was a problem.
そこで、この考案の目的は、吸引作業と排水作業とを排

When the pressure in the tank (2) is negative, the valve body (21) has a communication passage (20).
To close the check valve (18), and the water pressure of the clean water in the tank (2) causes the valve body (21) to slide to the left against the spring (23) force and open the communication passage (20). The check valve (18) is opened.
本考案は前記の如く構成で、次に作用について説明す
る。The present invention is constructed as described above, and its operation will be described below.
まず、吸引ホース(15)を開閉弁(7)に、排出ホース
(16)を開閉弁(10)にそれぞれ接続する。First, the suction hose (15) is connected to the open / close valve (7), and the discharge hose (16) is connected to the open / close valve (10).
次にブロア(3)を駆動させてタンク(2)内を負圧に
し、両方の開閉弁(7)(10)を開き、吸引ホース(1
5)の他端を吸引するための石ころ、空缶、泥、水等の
吸引物に近づける。Next, the blower (3) is driven to make the inside of the tank (2) a negative pressure, both opening / closing valves (7) and (10) are opened, and the suction hose (1
Move the other end of 5) to a suction object such as a stone, an empty can, mud, or water for suctioning.
これにより、石ころ、空缶、泥、水等の吸引物を吸引ホ
ース(15)、開閉弁(7)、吸込管(6)を通してタン
ク(2)内に収容する吸引作業を行うことができる。As a result, it is possible to perform a suction operation in which a suction object such as stones, an empty can, mud, and water is stored in the tank (2) through the suction hose (15), the opening / closing valve (7) and the suction pipe (6).
このとき、チェック弁(11)は第2図に示すようになっ
ている。すなわち、チェック弁(11)のフラッパ(14)
左側は大気圧、右側は負圧となっているので、フラッパ
(14)は反時計方向に揺動して連通路(13)を閉じてい
る。At this time, the check valve (11) is as shown in FIG. That is, the flapper (14) of the check valve (11)
Since the left side is atmospheric pressure and the right side is negative pressure, the flapper (14) swings counterclockwise to close the communication passageway (13).
吸引作業中において、タンク(2)内に石ころ、空缶、
泥、水等の吸引物がある程度収容されると、上水は石こ
ろや空缶より容易に分離し、第3図のように分離した上
水がパイプ(9)より上位置となると、上水の水圧によ
りフラッパ(14)は時計方向に揺動し、連通路(13)は
開かれ上水はパイプ(9)、チェック弁(11)、開閉弁
(10)、排出ホース(16)を通って排出される。During the suction work, stones, empty cans,
When the suctioned material such as mud and water is contained to some extent, the tap water is easily separated from the stones and the empty can, and when the separated tap water is located above the pipe (9) as shown in FIG. The water pressure of the flapper (14) causes the flapper (14) to swing clockwise, the communication passage (13) is opened, and clean water passes through the pipe (9), check valve (11), open / close valve (10), and discharge hose (16). Is discharged.
そして上水の水位がパイプ(9)より下位置となるとチ
ェック弁(11)が閉となって吸引作業のみとなり、その
後、また上水の水位がパイプ(9)より上位置となると
チェック弁(11)が開となって排出作業を行う。When the water level of the clean water is below the pipe (9), the check valve (11) is closed and only suction work is performed. After that, when the water level of the clean water is above the pipe (9), the check valve ( 11) is opened and discharge work is performed.
このようにして吸引作業を行いながら同時に自動的に排
水作業をすることができる。In this way, it is possible to automatically perform drainage work at the same time while performing suction work.
このとき吸入ホース(15)より吸引する吸引物の量を少
なくするとタンク(2)内の負圧は小さくなり、排水作
業をよりはやく行うことができる。At this time, if the amount of the suctioned substance sucked from the suction hose (15) is reduced, the negative pressure in the tank (2) is reduced, and the drainage work can be performed more quickly.
次に吸引作業が終了した場合には、両方の開閉弁(7)
(10)を閉じ、ブロア(3)を停止させた後、吸引ホー
ス(15)と排出ホース(16)とを開閉弁(7)(10)よ
りそれぞれ取り外す。Next, when the suction work is completed, both on-off valves (7)
After closing (10) and stopping the blower (3), the suction hose (15) and the discharge hose (16) are removed from the on-off valves (7) and (10), respectively.
