The valve sensing element 5 has a function of contacting and sensing the water control valve. Hereinafter, the structure of the ejector will be described in more detail. Here, FIG.
FIG. 5 is an enlarged view of the inside of the storage cylinder 3 in FIG. 4.

The mud discharging tool A of the present invention is provided with a handle shaft cylinder 1 for rotating the mud and sand from above the ground when the mud and sand is scraped up, and a storage cylinder 3 is attached to a lower portion thereof. It is preferable that the handle shaft cylinder 1 has a length that reaches at least from the ground surface GL to the water control valve 10. A gripping bar 11 is preferably inserted into the upper end of the handle shaft cylinder 1 in a detachable manner.

Therefore, the grip bar 11 can be attached only when the ejector A is used, and can be removed when not in use.
It is possible to easily store and carry the entire discharge device. Further, an L-shaped groove 12 composed of a horizontal groove 12B extending in the circumferential direction and a vertical groove 12A extending in the axial direction is formed in an upper portion of the handle shaft cylinder 1. On the other hand, inside the handle shaft tube 1, a down shaft 2 that is longer and protrudes into the storage tube body 3 is inserted. The claw portion 21 at the tip of the pull-down shaft 2 can be slid by fitting into the groove 12 described above.

The pull-down shaft 2 is movable in a region where the groove 12 is formed, and can be rotated up and down or at a fixed angle. A packing (not shown) for preventing rattling is attached to the outer periphery of the pull-down shaft 2 to prevent rattling when the pull-down shaft 2 moves inside the handle shaft cylinder 1.

An auger body 4 is attached to the pull-down shaft 2 in a state where the auger body 4 is covered with the storage cylinder 3. The auger body 4 has a cylindrical base 41 and a spiral formed on the surface thereof. And a blade 42. Top 4A of auger body 4
Is fixed to the pull-down shaft 2, and the top (top upper surface) of the auger body 4 is engaged with the top 3 A (top lower surface) of the storage cylinder 3.

By the way, a slightly thin tube portion 31 is extended above the top of the storage tube 3, and an upper spring S1 is mounted therein. The upper spring S1 acts to press the auger body 4 downward. A clutch cylinder 6 is loosely inserted into the base of the auger body 4, and a middle spring is disposed between the top 4 A of the auger body 4 and the clutch cylinder 6 so as to press the clutch cylinder 6 downward. S
2 are provided. In the initial state, the middle spring S2 is set to have a lower elastic force than a lower spring S3 described later.

On the other hand, an upper switching member 7 is attached to the lower end of the pull-down shaft 2, and a small-diameter rod 9 is extended downward from the upper switching member 7. Clutch cylinder 6
The upper engaging portion 6A meshing with the upper switching member 7
Are formed. On the other hand, on the lower bottom of the clutch cylinder 6,
The valve sensing element 5 including the shaft portion 51 and the edge blade 52 penetrates.

A lower switching member 8 is attached to the upper portion of the shaft of the valve sensing element 5, and a lower engagement portion 6 B that meshes with the lower switching member 8 is formed at the bottom of the clutch cylinder 6. In the shaft portion 51 of the valve sensing element 5, a fine hole 51A having a constant depth is formed along the center axis, and the small-diameter rod 9 of the upper switching member 7 and the small hole of the lower switching member 8 are formed. It is slidably inserted into 51A. The upward moving distance (escape distance) of the valve sensing element 5 is determined by the depth of the small hole 51A.
Is set.

A lower spring S3 is disposed between the top of the clutch cylinder 6 and the lower switching member 8, and resiliently moves the two in a direction away from each other. For this reason, in the normal state, the upper switching member 7 and the lower switching member 8 are engaged with each other via the clutch cylinder 6, and of course,
The down shaft 2 and the valve sensing element 5 can rotate integrally.

Here, regarding the storage cylinder 3, the storage cylinder 3 has a substantially cylindrical shape, and is capable of sufficiently storing mud and sand. An opening (opening width L) 31 extending in the longitudinal direction is formed in the side wall of the storage cylinder 3, and the distal end edge 31 of the side wall is radially outwardly expanded. The end edge 31 of the side wall is preferably processed into an edge blade so that the surrounding mud and sand can be easily removed.

The opening width L is, for example, about 3 cm. In order to efficiently introduce mud and sand, the width is appropriately selected depending on the form of mud and sand. In addition, it is preferable that an edge blade is provided on the lower edge of the storage cylinder 3 over the entire circumference in order to scrape down mud and sand. The structure of the mud and sand discharging tool A has been described above.
The mud and sand discharging operation using the mud and sand discharging tool A will be described.

1. First, the housing containing the water control valve 10, that is, the lid 101 of the valve box 100 is opened.

2. Next, the lowering shaft 2 of the discharging tool A is gripped and positioned near the center of the valve box 100 (see FIG. 4). At this time, the claw portion 21 of the pull-down shaft 2 is hooked into the horizontal groove 12B of the handle shaft cylinder 1 (in addition,
At this time, the upper spring S1 is in a state of contracting and accumulating resilience. Therefore, the top 4A of the auger body 4 is engaged with the top 3A of the storage cylinder 3 from below, and the auger body 4 and the storage cylinder 3 can move integrally. In the clutch cylinder 6, the upper switching member 7 and the lower switching member 8 are both meshed with the clutch cylinder 6 by the elastic force of the lower spring S3, and the valve sensing element 5 and the pull-down shaft 2 are connected to each other. Is a state that can move together. Therefore, by rotating the handle shaft cylinder 1, the housing cylinder 3, the auger body 4, and the valve sensing element 5 can rotate integrally as a whole.

3. Next, when the handle shaft cylinder 1 is rotated while being pushed while holding the grip bar 11, the storage cylinder 3, the auger body 4, and the valve sensing element 5 rotate integrally. Therefore, mud and sand around the storage cylinder 3 is shaved off by the distal end edge 32 of the side wall of the storage cylinder 3 and enters the inside through the opening 31. At the same time, auger body 4
By the rotation of, the mud and sand located on the bottom surface of the storage cylinder is filled between the spiral blades 42 of the auger body 4 (see FIG. 5).
In addition, the edge blade 52 of the valve sensor 5 cuts down mud and sand below.

4. Further, when the handle shaft cylinder 1 is pressed and rotated, the valve sensing element 5 comes into contact with the water control valve 10. In this case, the valve spring 5 moves slightly upward due to the contraction of the middle spring S2 in response to the valve sensor 5.

5. Further, when the handle shaft cylinder 1 is further pressed and rotated, the valve sensing element 5 cannot be moved further downward by the water control valve 10. Therefore, the valve sensing element 5 receives a certain pressure, the lower spring S3 contracts, and the lower switching member 8
Alternatively, the upper switching member 7 is released from the engagement with the clutch cylinder 6. As a result, the valve sensing element 5 does not rotate together with the storage cylinder 3 and the auger body 4, and the rotation of the valve sensing element 5 stops. Here, the rotational force is slightly reduced, and the operator senses that the discharging tool A, specifically, the valve sensor 5 has contacted the water control valve 10.

6. Further, when the handle shaft cylinder 1 is pressed and rotated, the valve sensor 5 escapes upward and the lower spring S3 contracts, but the small-diameter rod 9 which is an extension of the lowered shaft rod 2 has the shaft of the valve sensor 5. By hitting the bottom 51A1 of the small hole 51A of the part 51, the hand holding the handle shaft cylinder 1 feels (or senses) a collision with a click. At this point, the pressing rotation of the handle barrel 1 is stopped.

7. Next, the ejector A is pulled up, taken out of the housing (valve box 100), and replaced on the ground surface (see FIG. 7).

8. Finally, the claw portion 21 of the pull-down shaft 2 is removed from the horizontal groove 12B of the handle shaft cylinder 1. Upper spring S1
The auger body 4 is lowered and protrudes from the storage cylinder body 3 by the elastic force of.

9. When the handle shaft cylinder 1 is slightly tilted and lightly pucked on the ground surface GL, mud and sand adhering around the auger body 4 and mud and sand adhering to the inner surface of the storage cylinder are separated (see FIG. 3).

10. When the claw portion 21 of the pull-down shaft 2 is fitted into the horizontal groove 12B of the handle shaft cylinder 1, all the operations are completed. If there is a large amount of sediment in the casing and the valve sensing element 5 does not easily arrive at the water control valve 10 due to the first excavation work, the discharging tool A is pulled up from the casing during excavation, and the muddy soil is removed. It is good to discharge to the upper surface GL and repeat the same operation again using the discharge tool A until the water control valve 10 is exposed.

FIG. 9 shows another embodiment of the present invention. This discharging tool A1 comprises a handle shaft cylinder 1 and an auger body 4 fixed to a lower part thereof. In addition, handle shaft cylinder 1
A valve sensing element 5 having a concave portion covering the valve is provided at a lower end of the valve sensing element 5. This discharging tool also rotates while pressing the handle shaft cylinder 1 to capture and fill the mud and sand between the spiral blades around the auger body, and then discharges the mud and sand to the ground surface (A → B).

FIG. 10 shows still another embodiment. This discharging tool A2 has the degree of freedom of vertical movement of the valve sensing element 5 in the above-described embodiment by elastic force. Therefore, the valve sensing element 5 presses the water control valve 10 resiliently, so that the water control valve 10 is protected. FIG. 11 shows still another embodiment. The discharging tool A3 includes a storage cylinder 3 having a spiral blade 42A for scraping up mud and sand on its inner periphery, and a handle shaft cylinder 1 extended from the storage cylinder 3. Since the central portion of the storage cylinder 3 is hollow, the control valve in the valve box can escape when capturing and filling mud and sand. This discharging tool is also rotated while pressing the handle shaft cylinder 1 to push the storage cylinder 3 into the mud and sand, and at the same time, captures and fills the mud and sand between the spiral blades 42A of the storage cylinder 3 and then fills the ground surface. It discharges mud and sand. As described above, the present invention has been described.
In addition to the above-described embodiment, various modifications are possible. For example, the shapes of the storage cylinder, the auger body, and the valve sensing body are not limited to those in the drawings, and can be changed as appropriate.
