JP2013-165646A

Since the above-described conventional root vegetable cleaning apparatus cleans root vegetables with the high-pressure jet water sprayed from the spray nozzle, the root vegetables that have reached the discharge port are mixed.
In addition, when the root vegetable is moved by the height difference by providing a difference in height on the supply port side and the discharge port side of the roll brush, when the cleaning device is inconvenient and the height difference is small, Root vegetables may not move smoothly. In addition, when a roll brush planted in a spiral shape is used for the movement of root vegetables, a striped pattern may appear on the surface of the root vegetables.
In view of the above problems, the present invention provides a root vegetable cleaning device in which root vegetables are difficult to peel, and a root vegetable in which root vegetables easily move. An object is to provide a cleaning device.

In order to achieve the object of the present invention, the root vegetable cleaning device according to claim 1 rotates the root vegetables and forms two roll brushes or hairless rolls forming a movement path for the root vegetables in the axial direction. A plurality of spray nozzles that are arranged in parallel with each other and spray high pressure spray water above the movement path of the root vegetables are arranged in a row in the axial direction, and high pressure spray water is sprayed from each spray nozzle onto the root vegetables. In the root vegetable cleaning device, the pressure of the high-pressure jet water on the outer peripheral surface of the root vegetable is gradually reduced from the root vegetable supply port side of the cleaning device toward the root vegetable discharge port side. Features.
The root vegetable cleaning device according to claim 2 is the root vegetable cleaning device according to claim 1, wherein the crossing angle between the injection direction of the high-pressure jet water injected from the injection nozzle and the movement direction of the root vegetable is , Smaller than 90 degrees.
The root vegetable cleaning apparatus according to claim 3 is the root vegetable cleaning apparatus according to claim 1 or 2, wherein the spray nozzles arranged in a row form two or more rows. .
The root vegetable cleaning device according to claim 4 is the root vegetable cleaning device according to claim 1, claim 2 or claim 3, wherein the spray nozzles arranged in a row form a plurality of spray nozzle groups. The pressure of the high-pressure jet water on the outer peripheral surface of the root vegetable is set in units of the jet nozzle group.
The root vegetable cleaning device according to claim 5 is the root vegetable cleaning device according to claim 4, wherein the pressure of the pressurized water supplied from the pump to the plurality of spray nozzle groups is different for each spray nozzle group. It is characterized by that.
The root vegetable cleaning apparatus according to claim 6 is the root vegetable cleaning apparatus according to any one of claims 1 to 5, wherein the spray nozzle is configured to stop and adjust pressurized water for each spray nozzle. Means are provided.
The root vegetable cleaning apparatus according to claim 7 is the root vegetable cleaning apparatus according to any one of claims 1 to 6, wherein the roll brush or the hairless roll is a hairless roll. It is characterized by that.

Since the pressure of the high-pressure jet water on the outer peripheral surface of the root vegetable of the present invention gradually decreases from the supply port side to the discharge port side of the cleaning device, mud etc. of root vegetables are spray nozzles on the supply port side. Since the pressure injected from the water is dropped by the high-pressure jet water, and in the subsequent cleaning process, the high-pressure jet water having the low pressure is used to clean the root vegetables.
Further, when the angle between the injection direction of the high-pressure jet water sprayed on the outer peripheral surface of the root vegetable and the movement direction of the root vegetable is set to an angle smaller than 90 degrees, the high-pressure jet water is the outer periphery of the root vegetable. The surface is jetted (collised) obliquely with respect to the moving direction. Therefore, in this case, the root vegetables are smoothly moved because the root vegetables are subjected to a force for pushing the root vegetables in the moving direction by the high-pressure jet water. In addition, the peeling of the root vegetables is reduced as compared with the case where the high-pressure jet water is sprayed perpendicularly to the root vegetables.
Further, the oblique injection of the high-pressure jet water can be applied to a root vegetable cleaning apparatus that uses the height difference of the roll brush to move the root vegetables, and in that case, the height difference of the roll brush can be reduced.

1 shows a root vegetable cleaning apparatus according to an embodiment of the present invention. It is a figure explaining the pressure of the high pressure jet water in the outer peripheral surface of root vegetables in the cleaning apparatus for root vegetables which concerns on the Example of this invention. It is a figure explaining the several injection nozzle group in the washing | cleaning apparatus of root vegetables which concerns on the Example of this invention. It is a figure explaining the injection direction of the high pressure injection water injected to root vegetables in the cleaning apparatus for root vegetables which concerns on the Example of this invention. FIG. 4 shows an example in which three high-pressure water supply pipes are provided. Another embodiment of the roll brush and the spray nozzle in the root vegetable cleaning apparatus according to the embodiment of the present invention is shown. 1 shows a conventional root vegetable cleaning apparatus.

The inventor of the present invention experimented on the peeling condition of radishes and the like by spraying high-pressure jet water onto the radishes and the like of a conventional cleaning device for root vegetables such as radishes. As a result of the experiment, it was found that the radishes and the like peeled off as they moved to the discharge port side.
Also, regarding the cleaning action when jetting high-pressure jet water onto radishes etc., when dropping mud etc. such as radishes, it is necessary to increase the pressure of high-pressure jet water on the outer peripheral surface of radishes etc. In the cleaning process after dropping, it was found that not so much pressure was necessary. That is, it has been found that the pressure of the high-pressure jet water on the outer peripheral surface of the radish or the like does not have to be set constant from the supply port side to the discharge port side of the cleaning device as in the conventional cleaning device.
Therefore, in the present embodiment, two roll brushes or hairless rolls that rotate a radish or the like and form a movement path such as radishes are arranged in parallel in the axial direction, and the two roll brushes or hairless rolls A cleaning device for root vegetables such as radishes, in which a plurality of injection nozzles for injecting high-pressure spray water are arranged in a row in parallel with the axis of a roll brush or a hairless roll above (moving passages such as radishes) , The pressure of the high-pressure jet water on the outer peripheral surface of the radish and the like is set so as to increase toward the supply port side of the radish and decrease toward the discharge port side. That is, the pressure of the high-pressure jet water on the outer peripheral surface such as the radish is set in a stepwise manner so as to decrease toward the discharge port side.

Moreover, since the conventional root vegetable washing | cleaning apparatus injects high pressure spray water perpendicularly | vertically to outer peripheral surfaces, such as a radish, it was easy to peel off a radish.
Therefore, in the root vegetable cleaning apparatus of the present embodiment, the injection direction of the high-pressure jet water is set so that the angle between the injection direction of the high-pressure jet water and the moving direction of the radish or the like is smaller than 90 degrees. That is, the angle between the center line of the high-pressure jet water and the moving direction of the radish is set to be smaller than 90 degrees on the outer peripheral surface of the radish or the like.
In addition, it was found that when the injection direction of the high pressure jet water is set as described above, peeling of the radish and the like is reduced, and the high pressure jet water acts to push the radish and the like in the moving direction of the radish and the like. . Therefore, in this case, the heights of the two roll brushes or the hairless roll on the supply port side and the discharge port side can be made the same.

FIG. 1 shows an outline of a root vegetable cleaning apparatus according to an embodiment of the present invention.
1A is a plan view, FIG. 1B is a side view in the X2 direction in FIG. 1A, and FIG. 1C is an arrow direction of the X1-X1 portion in FIG. 1A. FIG. In FIG. 1, illustration of the hair of the roll brush is omitted. Further, FIG. 1A omits illustration of an injection pipe and an injection nozzle, which will be described later. The cleaning device in FIG. 1 is similar to the cleaning device in FIG. 32, roll brushes B1 and B2, and a pressurized water supply pipe 41 are provided. A large number (for example, 20) of injection pipes 42 are attached to the pressurized water supply pipe 41, and an injection nozzle 43 is attached to the injection pipe 42. The 20 injection pipes 42 and the injection nozzles 43 are the same.
The injection nozzle 43 can be directly attached to the pressurized water supply pipe 41 without providing the injection pipe 42. The injection nozzle 43 may be provided with a pressurized water stop / adjustment means such as a pressurized water stop / adjustment cock for each injection nozzle 43 for stopping the pressurized water supplied from the pressurized water supply pipe 41 or adjusting the amount of pressurized water. it can.
Further, the pressurized water supply pipe 41 is provided with a pressurized water supply port (not shown) for supplying pressurized water from a pump (not shown) at an end portion or a central portion. The two roll brushes B1 and B2 are rotated in the direction of arrow X4 in FIG. 1 (c) by a motor (not shown) through a driving force transmission means such as gears, chains, belts (not shown). To do.

The two roll brushes B1 and B2 are arranged in parallel with the axis at a predetermined interval, and serve as a passage through which the radish 51 moves. As for the movement path of the radish 51, two or more sets of roll brushes B1 and B2 may be provided to provide two or more movement paths. The pressurized water supply pipe 41 is disposed above the roll brushes B1 and B2 (moving path of the radish 51) in parallel with the axes of both roll brushes. The two roll brushes B1 and B2 are opposed to each other at an interval narrower than the diameter of the radish 51, and the interval can be adjusted by an interval adjusting means (not shown).
The pressurized water supply pipe 41 supplies pressurized water supplied from a pump (not shown) to the injection pipe 42 and the injection nozzle 43. The spray nozzle 43 sprays the high-pressure spray water 44 to the outer peripheral surface of the radish 51 vertically.
When the radish 51 is supplied onto the roll brushes B1 and B2 from the supply port 31, the radish 51 moves in the X3 direction while rotating on the movement path formed by both roll brushes. While moving in the X3 direction, the radish 51 is washed by the high-pressure spray water 44 sprayed from the spray nozzle 43 and moves to the discharge port portion 32.

The movement of the radish 51 in the X3 direction is performed by using the gravity based on the difference in height by providing the supply port portion 31 side of the roll brushes B1 and B2 higher than the discharge port portion 32 side. . Further, the movement of the radish 51 in the X3 direction can use the force of pushing the radish 51 in the X3 direction by the roll brushes B1 and B2 using the hair brushed in a spiral shape as the roll brushes B1 and B2. .
The roll brushes B1 and B2 are installed at the same height on the horizontal plane in FIG. 1C, but when both roll brushes rotate in the X4 direction, the radish 51 jumps out beyond the roll brush B2. There is. In this case, the radish 51 can be prevented from popping out by setting the roll brush B2 higher in the upper right than the roll brush B1. Moreover, in FIG.1 (c), you may install the plate-shaped body for jumping-out prevention of the radish 51 above the roll brush B2, etc. in the longitudinal direction of the roll brush B2. In FIG. 1C, when the radish 51 rotates in the direction opposite to the X4 direction, the roll brush B1 is installed higher than the roll brush B2. Similarly, a plate-like body for preventing the radish 51 from jumping out is installed above the roll brush B1.

Next, the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish 51 when the high-pressure jet water 44 is jetted on the outer peripheral surface of the radish 51 in FIG. 1 will be described with reference to FIG.
FIG. 2A is the same diagram as FIG.
FIG. 2B shows a position (horizontal axis) between the end Bin and the other end Bout of the roll brushes B1 and B2, and the high-pressure spray water 44 from the plurality of spray nozzles 43 disposed therebetween to the radish 51. The pressure (vertical axis) of the high-pressure jet water 44 on the outer peripheral surface of the radish 51 when jetted is shown. In FIG. 2B, the positions of white circles and black circles correspond to the positions of the injection nozzles 43 arranged between the end Bin and the end Bout. The white circle in the graph C1 indicates the pressure of the conventional cleaning device, and the black circle in the graph C2 indicates the pressure of the cleaning device of the present embodiment.
A plurality of, for example, 20 injection nozzles 43 are provided. That is, 20 injection pipes 42 are attached to the pressurized water supply pipe 41, and an injection nozzle 43 is attached to each of the injection pipes 42.

When 20 spray nozzles 43 are provided, the pressure on the outer peripheral surface of the radish 51 of the high-pressure spray water 44 sprayed from the 20 spray nozzles is constant as indicated by the white circle in the graph C1 in the case of a conventional cleaning device. However, in the case of the cleaning apparatus of the present embodiment, as shown by the black circle in the graph C2, it is set to become smaller (lower) stepwise from the end Bin side to the end Bout side.
In the case of the root vegetable cleaning device, the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish 51 requires a large pressure when dropping the mud of the radish 51, but may be relatively small in the subsequent cleaning process. Therefore, in the cleaning apparatus of this embodiment, the pressure on the outer peripheral surface of the radish 51 is increased (higher) toward the end Bin side and decreased (lower) toward the end Bout side, that is, as shown in the graph C2. It is set up.
The root vegetable cleaning apparatus of the present embodiment can reduce the occurrence of scratches such as peeling of the radish 51 by setting the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish 51 as described above. .

Next, a means for setting the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish 51 as indicated by a black circle in the graph C2 will be described.
The pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish 51 varies depending on the following conditions.
The pressure includes, for example, the pressure of pressurized water supplied from a pump (not shown) to the pressurized water supply pipe 41, the injection pressure of the injection nozzle 43, the distance between the injection hole of the injection nozzle 43 and the outer peripheral surface of the radish 51, and high-pressure injection water. It depends on conditions such as the angle of the 44 injection directions. Thus, changing one or more of these conditions will change the pressure.
For example, in FIG. 2A, when the height H12 on the end Bout side of the pressurized water supply pipe 41 is set higher than the height H11 on the end Bin side (H12> H11), in this case, the injection nozzle The distance between the 43 injection holes and the outer peripheral surface of the radish 51 is different for each injection nozzle 43.
The heights H11 and H12 are preferably the distance between the pressurized water supply pipe 41 and the outer peripheral surface of the radish 51, but in practice, the pressurized water supply pipe 41 and the outer peripheral surface of the roll brush B1 or B2, the roll brush It may be a distance from the shaft or the moving path of the radish 51. In any case, when accurate setting is required, means for adjusting the pressure of the pressurized water supplied from the pump, the heights H11, H12, and the like are provided, and the high-pressure jet water on the outer peripheral surface of the radish 51 is provided. It is desirable to adjust the pressure of 44.

Further, the height of the pressurized water supply pipe 41 is not changed (H11 = H12), and the length of the injection pipe 42 may be made different for each injection nozzle 43 so as to be longer toward the end Bin side. Further, the spray pressure of the spray nozzle 43 or the pressure of pressurized water supplied to the supply pipe 41 may be made different for each spray nozzle 43, and the spray pressure or the pressure of pressurized water may be set higher toward the end Bin side.
Further, the high-pressure water 44 is supplied from the pressurized water supply pipe 41 by operating the pressurized water stop / adjustment means provided in each of the injection nozzles 43 according to the cleaning condition of the radish 51 and the moving condition such as the moving speed. Can also be stopped and adjusted. In this case, for example, the pressurized water may be stopped every other of the 20 injection nozzles 43, or the pressurized water at a specific place may be stopped. It is arbitrary whether to stop and adjust the pressurized water supplied to which injection nozzle 43.
In FIG. 2A, when adjusting means such as the pressure of pressurized water supplied from the pump and the heights H11 and H12 of the pressurized water supply pipe 41 are provided, the thickness, type, and mud condition of the radish 51 are increased. Accordingly, the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish 51 can be adjusted.

FIG. 3 is an example in which the pressure of the high-pressure jet water on the outer peripheral surface of the radish is set in units of jet nozzle groups.
3 (a) and 3 (b) are side views similar to FIG. 2 (a). Illustration of radish is omitted.
3A and 3B divide the pressurized water supply pipe, the injection pipe, and the injection nozzle of FIG. 1 into two groups of a pressurized water supply pipe 411 and a pressurized water supply pipe 412 to form two injection nozzle groups. It is. For example, when there are 20 injection nozzles, 10 nozzles are divided into an injection nozzle group of the pressurized water supply pipe 411 and an injection nozzle group of the pressurized water supply pipe 412. The two injection nozzle groups use the pressurized water supply pipes 411 and 412, the injection pipe 42, and the injection nozzle 43 under the same conditions.

In FIG. 3A, the heights H21 and H22 of the pressurized water supply pipes 411 and 412 are set to be the same (H21 = H22).
In the case of FIG. 3A, when the pressure (P11) of the pressurized water supplied from the pump to the pressurized water supply pipe 411 is set higher than the pressure (P12) of the pressurized water supplied to the pressurized water supply pipe 412 (P11> P12), The pressure of the high-pressure jet water 44 on the outer peripheral surface of the jet nozzle group of the pressurized water supply pipe 411 is higher than that of the jet nozzle group of the pressurized water supply pipe 412. Therefore, in the case of FIG. 3A, the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish is set in two stages for each jet nozzle group.

In FIG. 3B, the height H32 of the pressurized water supply pipe 412 is set higher than the height H31 of the pressurized water supply pipe 411 (H32> H31).
In the case of FIG. 3B, if the pressure of pressurized water supplied from the pump to the pressurized water supply pipe 411 (P11) and the pressure of pressurized water supplied to the pressurized water supply pipe 412 (P12) are set to the same (P11 = P12), The pressure of the high-pressure jet water 44 on the outer peripheral surface is higher in the jet nozzle group of the pressurized water supply pipe 411 than in the jet nozzle group of the pressurized water supply pipe 412 as in the case of FIG. Therefore, in the case of FIG. 3B, the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish is set in two stages for each jet nozzle group, as in the case of FIG. .
3A and 3B, the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish is such that the jet nozzle group of the pressurized water supply pipe 411 is like a black circle in the graph C21, and the jet nozzle of the pressurized water supply pipe 412 The group becomes like a black circle in the graph C22.

FIG. 3 shows an example in which two injection nozzle groups are provided. However, the number of injection nozzle groups is not limited to two, and two or more injection nozzle groups are provided, and the pressure of the high-pressure injection water 44 on the outer peripheral surface of the radish is determined. In FIG. 3, which can be set in two or more stages in units, if a means for adjusting the height of the pressurized water supply pipes 411 and 412 and the pressure of the pressurized water supplied to the pressurized water supply pipes 411 and 412 is provided, the high pressure on the outer peripheral surface of the radish The pressure of the jet water 44 can be adjusted according to the thickness of the radish, the type, the degree of mud attachment, and the like.
Also in the case of FIG. 3, the pressurized water stopping / adjusting means for the spray nozzles 43 belonging to each spray nozzle group can be provided for each spray nozzle 43.
In addition, the setting of the pressure of the high-pressure jet water 44 on the outer peripheral surface of the radish is simpler when the number of setting steps is small.

FIG. 4 shows an embodiment in which two pressurized water supply pipes are installed.
4A is a plan view, FIG. 4B is an enlarged view of a part of FIG. 4A, and FIG. 4C is an arrow direction of the X1-X1 portion of FIG. 4A. It is sectional drawing. In FIG. 4, illustration of the hair of the roll brush is omitted. In FIG. 4A, the illustration of the injection pipe and the injection nozzle is omitted.
The pressurized water supply pipes 41a and 41b are installed above the roll brushes B1 and B2 (the movement path of the radish 51) in parallel with the axes of both roll brushes.

The high-pressure jet waters 44a and 44b jetted from the jet nozzles 43a and 43b are jetted (collised) on the outer peripheral surface of the radish 51 at angles θa and θb with respect to the moving direction X3 of the radish 51. That is, the intersecting angles between the jetting direction of the high-pressure jet water 44a and 44b and the moving direction X3 of the radish 51 are θa and θb. The angles θa and θb in the present embodiment are the same and are set to an angle smaller than 90 degrees (θa = θb <90 degrees). In FIG. 4B, the outer peripheral surface of the radish is described as a surface parallel to the moving direction X <b> 3 of the radish 51.
Since the force which pushes the radish 51 in the X3 direction by the injection nozzles 43a and 43b is applied to the radish 51, the radish 51 becomes easy to move in the X3 direction. Therefore, the roll brushes B1 and B2 can be configured so that even if the supply port side and the discharge port side of the cleaning device are at the same height or the height difference between the supply port side and the discharge port side is reduced, , Move smoothly in the X3 direction.
In addition, the radish 51 is harder to peel than the case where the high-pressure spray water 44a and 44b is sprayed perpendicularly to the outer peripheral surface of the radish 51, and the high-pressure spray water 44a and 44b is sprayed from two directions on the radish 51. Therefore, the cleaning effect is also increased.
In FIG. 4, the angle can be set to an optimum state by providing means for varying and adjusting the injection direction of the high-pressure jet water from the jet nozzles 43 a and 43 b.
Also in the case of FIG. 4, the pressurized water stopping / adjusting means for the spray nozzles 43 a and 43 b can be provided for each spray nozzle.

FIG. 5 shows an embodiment in which three pressurized water supply pipes are juxtaposed by adding a pressurized water supply pipe 41c to the pressurized water supply pipes 41a and 41b of FIG.
5A is a plan view, FIG. 5B is a cross-sectional view of the X1-X1 portion in the arrow direction in FIG. 5A, and FIG. 5C is X2 in FIG. FIG. 5D is a partially enlarged view of FIG. 5A (the roll brushes B1 and B2 are not shown). Omitted).
The pressurized water supply pipe 41c is disposed above the pressurized water supply pipes 41a and 41b (the movement path of the radish 51).
Since the pressurized jet water 44a, 44b, 44c is sprayed from the three directions at angles θa, θb, θc to the radish 51, the cleaning effect is further increased, and the radish 51 moves more smoothly in the X3 direction. .
In FIG. 5, the pressurized water supply pipe may be provided with only one pressurized water supply pipe 41c, as in the conventional root vegetable cleaning apparatus.
Also in the case of FIG. 5, the pressurized water stopping / adjusting means for the injection nozzles 43a, 43b, 43c can be provided for each injection nozzle.

FIG. 6 shows another embodiment of the roll brushes B 1 and B 2 and another embodiment of the spray nozzle 43.
First, FIGS. 6A and 6B will be described.
6A1 and 6B1 are plan views, and FIGS. 6A2 and 6B2 are cross-sectional views of the X5-X5 portion in the arrow direction in FIGS. 6A1 and 6B1.
The rolls of FIGS. 6A and 6B are rolls having no hair on the surface (hereinafter referred to as “hairless roll”).
The hairless roll 61 of FIG. 6A is planted in the core member 612, and the planted hair is covered with a resin sheet (film) 611 such as vinyl. That is, it corresponds to a conventional roll brush covered with a resin sheet 611. In the hairless roll 61, the hair implanted in the core member 612 has a cushioning action.
The hairless roll 62 in FIG. 6B is made of an elastic material such as sponge, foamed resin, or rubber. The hairless rolls 61 and 62 can be used in place of the roll brushes B1 and B2 in the root vegetable cleaning apparatus of FIG. Since the surfaces of the hairless rolls 61 and 62 have elasticity and the hair of the roll does not touch the radish, the radish skin is not peeled off by the hair like a roll brush during the cleaning process. Further, the radish rotates in the process of movement as in the case of the roll brushes B1 and B2.
Since the hairless rolls 61 and 62 form a thin layer of water between the hairless rolls 61 and 62 and the radish when the radish moves, like the root vegetable cleaning apparatus of FIGS. 4 and 5, This is particularly suitable in the case of a cleaning device in which high-pressure jet water contributes to promoting movement of radishes and the like.

Next, FIG. 6C will be described.
6 (c1) is a plan view, FIG. 6 (c2) is a cross-sectional view of the X6-X6 portion in FIGS. 6 (c1) and (c3), and FIG. 6 (c3) is FIG. ) Is a cross-sectional view of the X7-X7 portion in the arrow direction.
The injection nozzle 71 in FIG. 6C has a plurality of injection holes 713 for injecting high-pressure injection water into a long pipe 711 in a line in the axial direction of the pipe 711. The tube 711 has an opening 712 at one end and closes the other end. Pressurized water is supplied to the opening 712 from a pump (not shown).

The injection nozzle 71 may be the same as the pressurized water supply pipe 41 of FIG. 1 as the pipe 711, and a large number, for example, 20 of the injection holes 713 may be formed in the pressurized water supply pipe 41.
The injection nozzle 71 having a plurality of injection holes 713 has the same function as the pressurized water supply pipe 41 having a plurality of injection pipes 42 and a plurality of injection nozzles 43 shown in FIG. It corresponds to 43.
Therefore, in the present invention, the term “injection nozzle” including the injection hole 713 is defined, and the injection nozzle 71 may be referred to as a long injection nozzle.
Further, the long injection nozzle 71 can be divided to form a plurality of injection hole groups (injection nozzle groups) in the same manner as the pressurized water supply pipes 411 and 412 in FIG.
A pressurized water stop / adjustment means for opening and closing the injection hole 713 can be provided for each injection hole 713 on the outer peripheral surface of the pipe 711.
