Description

  TECHNICAL FIELD The present invention relates to a planting device for planting (planting) a plant and a planting method, and more particularly, planting that is optimal for planting a plant such as reed in a lake or its waterside. The present invention relates to a device for planting and a planting method.

  For example, in order to plant a plant such as reed on the bottom of a lake, it is necessary to dig a hole in the bottom. However, it is necessary to embed not only the root of the reed but also the lower part of the stem from the viewpoint of maintaining the plant upright after planting. For example, a reed with a total length of 1 to 1.5 m is about 50 cm in the bottom of the water. It is said that it is necessary to dig deep holes.

  In other words, reeds must always be kept upright even when exposed to wave winds, especially in the shallow waters of lakes, where the bottom of the water constantly fluctuates due to waves. Even in such an environment, it is necessary to reliably maintain a planted state.

  However, even if an attempt is made to dig a deep hole in the bottom of the water in consideration of the above, earth and sand existing around the hole flows into the hole at the same time as the hole is dug. For this reason, even if it continues digging, the surrounding earth and sand flows into the hole and the hole is buried, and it is very difficult to form a deep hole for planting reed, and the work efficiency is extremely bad. Have the problem.

  Therefore, an object of the present invention is to provide a planting device and a planting method that can be planted efficiently even when plants are planted in watersides and shallow waters such as lakes.

  The planting device of the present invention is a planting device for forming a planting hole for planting a plant in the bottom of the water, and planting the plant upright with respect to the bottom of the plant. A tubular planting tube used in an upright position, and a fluid is ejected from the lower end opening of the planting tube toward the water bottom, and the planting hole is formed in the water bottom. In order to form, it comprises a fluid supply means for supplying a fluid to which pressure is applied to the inside of the planting tube connected to the upper end opening of the planting tube, and the planting tube is The plant is formed so as to be insertable.

  The fluid supply means includes, for example, a compressor (compressor), a pump, and the like, and when the fluid is ejected toward the bottom of the planting tube, the planting hole is formed in the bottom of the water. Any desired pressure and flow rate that can be applied may be used.

  Moreover, the said planting apparatus is made to contact the peripheral part of the said planting hole part, and the stopper which regulates that the said planting hole part is dug down by pressing down the said planting tube Preferably, the member is provided on the outer periphery.

  The stopper member may be configured so that its position in the length direction can be adjusted when it is attached to the planting tube as long as it can regulate the digging of the planting hole. Good. For example, one having a structure that is slidably fitted to a planting tube, or one that has a screw part that is attached to the outer periphery of the planting pipe by screwing. Etc. Further, the stopper member is made of a synthetic resin, a rubber member, a punched wire mesh, a U-shaped rod-shaped member (using a U bolt), a disk shape, or a radial shape. There may be, and the material and form are not limited.

  The fluid contains either gas or liquid, and when the fluid is liquid, water existing in the vicinity of planting the plant may be used.

  Moreover, the planting method according to the present invention is a method in which a fluid is applied to the inside of the planting tube raised from the water bottom by the fluid supply means connected to the upper end opening of the planting tube. The bottom of the bottom of the planting tube is pressed down while the injected fluid is ejected from the bottom end of the planting tube, and the bottom of the plant facing the bottom end of the planting tube And removing the fluid supply means from the upper end opening of the planting tube, inserting the plant, and supporting the planting hole with the planting hole The planting tube can be removed and planted.

  In the planting method, earth or sand or fertilizer may be injected into the planting hole through the planting tube with the plant inserted.

  The material of the tube for planting is not limited, such as a vinyl chloride tube, a steel tube, or a tube formed of metal such as aluminum or wood.

  According to the invention which concerns on Claim 1 or Claim 4, a fluid can be ejected directly from the vicinity of the desired location which wants to form the hole part for planting in a water bottom. And since it digs only by pushing down a pipe | tube, it can remove the earth and sand of the location accurately and efficiently, and can form the deep hole for planting.

  In addition, even if the hole for planting formed by the planting device is a deep and thin hole, it is physically confirmed that the earth and sand flows into the hole for planting by the tube for planting. Since it can be prevented, the depth of the hole once dug can be maintained. And a plant is planted in the state regulated by the tubular body for planting of an upright state. Plants planted in this way are kept upright by earth and sand, so they can be planted easily, and keep upright even if typhoons come and are exposed to storms Can be planted.

  Furthermore, the planting device is a work for forming planting holes necessary for planting plants, a process for storing plant roots and stems in the planting holes, and a work for applying earth and sand and fertilizer. Any of these tasks can be covered.

In particular, in the operation of forming the planting hole portion, since it is not necessary to perform it manually, labor is not required and it can be easily formed even at the bottom of the water.
Even in the operation of storing the root of the plant in the hole for planting, it is not necessary to bend and waist, and even the bottom of the water can be planted without being soiled.

  According to the invention which concerns on Claim 2, the depth of the hole for planting can be set to a desired depth by using the said stopper member. For this reason, in the case of planting a plurality of plants, it is possible to plant in a state where all the plants have the same height. And it becomes a standard for the operator that the tube for planting should just be pushed down until the above-mentioned stopper member contacts the bottom of the water. For this reason, even if it is a case where a water bottom cannot be visually observed, an operator does not need to plant, making extra adjustment, and work efficiency improves.

According to the invention of claim 3, since it is a fluid source that uses fluids such as lakes and marshes that are close to us, there is no need to separately prepare fluids, and the fluids that have been used are again supplied to lakes and the like. Since it is reduced, it can be used without limitation and is efficient. Moreover, it can be planted at low cost and is easy for the environment.
According to the invention which concerns on Claim 5, since earth and sand and a fertilizer can be inject | poured directly toward the root of a plant, it is efficient and can apply earth and sand easily. Furthermore, after forming the hole for planting, the tube for planting can be poured as it is while being inserted into the hole for planting, so after forming the hole for planting, work to smoothly apply earth and sand etc. Can be migrated to.

An embodiment of the present invention will be described below with reference to the drawings.
Here, using the planting device 11 according to the present embodiment, taking up the work of planting reed A on the bottom of a lake with a water depth of about 80 cm, the method and procedure will be mainly described. The configuration of the planting device 11 will be described.

  As shown in FIG. 1, the planting device 11 mainly includes a planting tube 12 and a water absorption pump 13. The planting tube 12 is composed of a cylindrical synthetic resin tube.

  The total length of the planting tube 12 is about 150 cm. The length of the planting tube 12 is the length of the plant to be planted, the depth of the hole to be dug for planting, and the planting tube for working. Depending on the ease of handling of the body 12 itself, for example, it can be arbitrarily determined between about 80 to 160 cm as a guide.

And it is the lower end side when raising the said tubular body 12 for planting with respect to the water bottom B, Comprising: About the outer peripheral part located about 40 cm upwards from the lower end opening part 12a opened on this lower end side Is fitted with an annular stopper plate 16 made of synthetic resin, and the stopper plate 16 is attached to the planting tube 12 in a bowl shape.
In addition, the said board | plate material 16 for stoppers can adjust an attachment position arbitrarily by sliding with respect to the length direction of the tubular body 12 for planting.

  On the other hand, one end side 17a of the connecting tube 17 disposed from the water absorption pump 13 side is connected to the upper end opening 12b of the planting tube 12 in order to connect to the planting tube 12. Are detachably attached via an adapter 18.

  In addition, although the internal diameter of the said tube 17 for a connection is about 50 mm, what is necessary is just to set according to the internal diameter of the tubular body 12 for planting. As a guide, when using the planting tube 12 having a diameter of 100 mm, the connecting tube 17 has a cross-sectional area of 1 with respect to the planting tube 12, such as using the connecting tube 17 having a diameter of 50 mm or more. It is preferable to use the connecting tube 17 having a thickness of / 4 times or more.

Then, about the said water absorption pump 13, it uses the commercially available engine pump and is mounted on the boat 19 which has floated on the lake surface as shown in FIG.
In addition, the said water absorption pump 13 is not limited to mounting on the said boat 19, You may install in land and use it suitably.

  On the output side portion 13 a of the water absorption pump 13, an end portion 17 b opposite to the side attached to the planting tube 12 in the connection tube 17 is attached.

On the other hand, a water absorption tube 21 is connected to the input side portion 13b of the water absorption pump 13, and the tip side of the water absorption tube 21 is suspended in the lake.
The planting device 11 in the present embodiment is configured as described above, and the procedure for planting the reed A using the planting device 11 will be described below.

  First, when an operator (not shown) operates the water absorption pump 13 while holding the planting tube body 12 upright with respect to the water surface, the water absorption pump 13 draws water from the lake. The water sucked up and compressed is compressed in the water suction pump 13. For this reason, the water output from the output side of the water absorption pump 13 is supplied into the planting tube 12 in a state where pressure is applied.

And since the water supplied in the tube 12 for planting reaches the lower end side of the tube 12 for planting, maintaining the applied water pressure, it spouts from the lower end mouth part 12a vigorously (A of FIG. 1). reference).
Here, as a guide, the amount of water ejected from the lower end opening 12a of the planting tube 12 and the water pressure will be described.
The amount of water to be ejected when the inner diameter of the planting tube 12 is 10 cm, for example, is preferably about 500 liters or more per minute, and the amount of water to be ejected when the inner diameter of the planting tube 12 is, for example, 15 cm Is preferably about 1000 liters or more per minute.
At this time, if the water pressure in each of the above cases is about 2.5 kg or more per 1 cm ² , it is possible to obtain a pressure that can sufficiently dig the bottom of the water.

  In this state, the operator pushes it down little by little while holding the planting tube 12.

  Then, as shown in FIG. 2, water can be ejected from the lower end opening 12 a of the planting tube 12 toward the water bottom B, so that it faces the lower end of the planting tube 12 in the water bottom B. You can remove the earth and sand and dig it down.

  Then, as shown in FIG. 3A, when the planting hole 23 is dug down, it reaches about 40 cm, and as shown in FIG. 3B, the bottom surface of the stopper plate 16 is formed. Comes into contact with the peripheral edge of the hole 23 for planting.

  In this way, the stopper plate 16 can restrict the planting tube 12 from moving further downward. Then, the operator himself senses that the stopper plate 16 has come into contact with the water bottom B, and stops pressing the planting tube 12 further.

  Even if the pressing of the planting tube 12 is stopped, the soil and sand in the planting tube 12 has already been discharged, so the planting hole 23 is finally about 40 cm to 50 cm. Can be formed to a depth of

Next, the operator removes the adapter 18 connected to the upper end opening 12b of the planting tube 12.
Since the stopper plate 16 supports the planting tube 12 in an upright state, the adapter 18 can be easily maintained even if the operator does not continue to hold the planting tube 12. It can remove from the upper end opening part 12b of the tubular body 12 for planting.

  As described above, by removing the adapter 18, since water is not supplied into the planting tube 12, the ejection of water from the lower end of the planting tube 12 stops. Then, as shown in FIG. 4, the operator repels the upper end 12 b of the planting tube 12 while inserting the lower end of the planting tube 12 into the planting hole 23 as it is. Insert A with its root side down.

  When the above-mentioned reed A descends the inside of the planting tube 12, the wall surface of the planting tube 12 is present on the entire outer periphery thereof. For this reason, it can control that Yoshi A falls down, and can guide the root part of Yoshi A in the hole 23 for planting in an upright state. At the same time, since the reed A is protected by the planting tube 12, it is not hindered by other external factors existing in the water such as aquatic plants on the way down, so that it can be lowered smoothly without being damaged. .

  Subsequently, as shown in FIG. 5, the worker injects earth and sand or fertilizer C little by little from the upper end opening 12 b of the planting tube 12.

  The earth and sand and the fertilizer C injected into the planting tube 12 pass through the planting tube 12 while passing through the space between the inner wall surface of the planting tube 12 and the reed A, and then reliably. It fills in the hole 23 for planting. And as shown in FIG. 6, the tube 12 for planting is extracted from the hole 23 for planting, and also the tube 12 for planting is lifted upwards with respect to the reed A, and is extracted from the reed A. The planting of reed A is completed as shown in FIG.

  As described above, the root portion of the reed A and the stem portion on the lower side can be embedded in the water surface while maintaining the reed A in an upright state with respect to the water bottom B.

  The following effects can be produced by the planting device 11 according to the present embodiment and the planting method according to the present embodiment described above.

  Conventionally, it was very difficult to dig a deep hole in the bottom of the water using a tool such as a scoop because earth and sand flow into the hole. Moreover, it has been difficult to dig a hole with a small diameter deep in the bottom of the water with a scoop or the like. However, if the planting apparatus 11 according to the present embodiment and the planting method according to the present embodiment are applied, the fluid is directly ejected from the vicinity of a desired location where a hole for planting in the water bottom is to be formed. be able to. And since it digs only by pushing down a pipe | tube, it can remove the earth and sand of the location accurately and efficiently, and can form the deep hole for planting.

  That is, it is possible to easily form a deep and narrow hole that is optimal for reed planting.

  In addition, the worker does not need to bend or stretch his / her waist in the above-described series of operations, and thus does not require labor. For example, as long as he / she wears boots, waders (waterproof pants), etc. Will not get dirty.

  Further, as in this embodiment, the operator himself can plant while on the boat 19, etc., and even in this case, the whole body is not contaminated and is safe against water accidents. .

Furthermore, since the tube 12 for planting itself is lightweight and the water absorption pump 13 is mounted on the boat 19, the movement while planting can also be performed easily.
Moreover, the planting apparatus 11 performs the operation | work which forms the hole 23 for planting required in the operation | work which plants a plant, the operation | work which puts the root of a plant in the hole 23 for planting, and also earth and sand and fertilizer Any work can be covered.

  In addition, since the planting device 11 can use a fluid such as a lake or the like that is close to the plant, it is not necessary to prepare a separate fluid, and the fluid used is reduced again to the lake and the like. Therefore, it can be used without limitation and is efficient. Furthermore, it can be planted at low cost and is easy for the environment.

  Moreover, even if the distance until the water output from the water absorption pump 13 is ejected from the lower end opening portion 12a of the planting tube 12 is long, the water passing between them is connected to the planting tube 12 and the connection. It is in a state of being blocked by the tube 17 for use. For this reason, the water pressure applied by the water absorption pump 13 is not attenuated midway due to external factors, and water can be efficiently ejected.

  Furthermore, if the said planting apparatus 11 is used, the hole 23 for planting of the form which is hard to form with a scoop etc. can be formed. That is, by changing the pressure applied to the fluid by the water absorption pump 13 or the diameter of the tube body 12 for planting, the planting hole 23 having a desired shape such as a thinner and deeper shape can be formed.

  For this reason, even if it is a case where several reed A is clustered in the state adjacent to each other, it can plant easily. Moreover, even in a narrow place where the reed A is mixed, the surrounding reed A can be easily planted without falling down.

  Moreover, in any case of the operation | work which inserts the reed A into the tube 12 for planting, or the operation | work which extracts the tube 12 for planting from the reed A, the inner peripheral surface of the tube 12 for planting and reed A Are also slid against each other, the frictional force generated thereby acts in the same direction as the direction in which leaves grow from the stem of reed A. For this reason, Yoshi A does not hurt.

  As mentioned above, although the planting apparatus 11 which concerns on this embodiment, and the planting method which concerns on this embodiment were demonstrated, the planting apparatus 11 which concerns on this invention, and the planting method which concerns on this invention are the above-mentioned. The method and procedure for planting can be changed as appropriate according to the plant to be planted or the surrounding environment.

  For example, in the above-described planting method, earth and sand and fertilizer C are injected into the tube 12 for planting, but it is not essential to inject earth and sand and fertilizer C in this way, and as necessary, Just inject. That is, depending on the soil quality of the bottom B, at the moment when the tube 12 for planting is extracted from the hole 23 for planting, the earth and sand existing around the hole 23 for planting is gradually inside the hole 23 for planting. It flows into and is filled. In such a case, it is not necessary to inject soil and fertilizer C again, and the reed A can be planted in a standing state.

  Further, for example, if the soil quality at the bottom of the water does not allow soil or sand to flow into the planting hole 23 even if the planting tube 12 is extracted from the planting hole 23, the planting tube 12. The root part and stem part of reed A may be inserted into the hole part 23 for planting in the state of having been extracted, and earth and sand etc. may be caused to flow into the hole part 23 for planting with hands and feet.

  Of course, as in this embodiment, when planting on the bottom B, the operator himself may plant the water pump 13 on the boat 19, but the water pump 13 is directly placed on the land. You may install and arrange | position the said tube 17 for a connection to the place which plants the bottom B.

  In addition, the planting device 11 and the planting method are not limited to lakes, and can be applied to swamps, ponds, rivers, seas, and the like. You may plant reed A etc.

  When the planting device 11 is used at such a waterside, the planting hole 23 is not necessarily actively formed by ejecting water from the lower end of the planting tube 12 as described above. For example, the originally soft ground may be liquefied and planted. Thereby, roots, such as reed A, can be planted easily in the liquefied location.

  The plant to be planted is not limited to the above-mentioned Yoshi A (or persimmon), but also includes rice, seaweed (including seaweed), etc., and the target plant is not particularly limited.

  Moreover, you may comprise the said tubular body 12 for planting so that the length is variable as other embodiment. Specifically, the tube 12 for planting is divided into a plurality of members in the length direction, and the ends are screwed together or fitted together so that they can be connected. It is good also as a structure. In addition, it is good also as a structure which can be expanded-contracted like an antenna or a fishing rod.

  If the said structure is employ | adopted, according to the water depth, the height of the plant to plant, etc., it can comprise and use for the length which is the easiest to plant.

  Furthermore, as shown in FIG. 8, the planting tube 25 may be formed such that a portion excluding the lower side in the length direction has a larger diameter than the lower side portion.

If this structure is taken, when earth and sand and the fertilizer C will be inject | poured from the upper end opening part 12b of the tubular body 25 for planting, this earth and sand and the fertilizer C can be dropped more smoothly to the lower side.
Moreover, since the diameter on the lower side is small, the fluid is compressed at the lower end opening 12a and can be ejected vigorously.

  Furthermore, although the depth of the hole part 23 for planting was set with the said board | plate material 16 for stoppers, the structure which sets the depth of the hole part 23 for planting is not limited to the structure of the said board | plate material 16 for stoppers, for example, As shown in FIG. 9A, the outer peripheral surface on the upper side of the planting tube 12 may be marked 31.

  For example, when the bottom of the water is brittle, the stopper plate 16 may be submerged when brought into contact with the bottom of the water, so that the accurate depth may not be detected. However, if the above-mentioned planting tube 12 with the mark 31 on the outer peripheral surface on the upper side is used, the mark 31 is used for the planting tube 12 until the mark 31 coincides with the water surface in the downward direction. It is a sign that it should be pushed down. For this reason, also in this structure, the hole 23 for planting can be set to a desired depth.

  In addition, as shown in FIG.9 (b), it is good also as a structure which connected the string-like body 33 which provided the float 32 in the front-end | tip part to the outer peripheral side of the tube body 12 for planting.

  In the case of adopting the above configuration, the string-like body 33 may be adjustable in a stretchable manner, and the depth of the planting hole 23 may be arbitrarily adjusted by expanding and contracting.

  Furthermore, if the said structure is taken, the depth of the hole 23 for planting to form arbitrarily can be set irrespective of the soil quality of a water bottom. In addition, the planting tube 12 can be easily carried in water.

  Further, for example, the end side 17a connected to the planting tube 12 in the connecting tube 17 may be formed with a branch valve 31 (switching valve) interposed as shown in FIG. Good.

  If the said structure is taken, when an operator wants to stop the outflow of water, for example, when forming the hole 23 for planting to the desired depth, when planting, it is the water absorption pump 13 one by one. Thus, it is not necessary to perform the ON / OFF operation of the power (driving source) of the water suction pump 13 and no need to make another worker stand by in the vicinity of the water suction pump 13 at all times.

    Further, for example, a branch valve 31 (switching valve) may be interposed on the end side 17b connected to the water absorption pump 13 side in the connection tube 17 as shown in FIG.

  If the above configuration is adopted, it is necessary to wait for the worker also on the water absorption pump 13 side. However, when the engine pump is used for the water absorption pump 13 as in this embodiment, the engine pump is driven or stopped each time. The flow rate can be easily adjusted by operating the lever of the branch valve 31 without the need for any adjustment.

  That is, since the outflow of water can be easily stopped based on the judgment of the operator who performs planting, work efficiency is remarkably improved.

Incidentally, the configuration of the branch valve 31 shown in FIGS. 10A and 10B includes a box body 32 through which a fluid passes as shown in FIG. 10C and flows into the box body 32. It is provided with a lever 33 that can be adjusted as appropriate to allow the fluid to pass directly to the planting tube 12 or to flow out of the connecting tube 17.
Specifically, the lever 33 is provided on the outside of the box 32, and when the lever 33 is tilted, the shaft inside the box 32 rotates in conjunction with the lever 33, and the lever 33 is integrated with the shaft. Since the lid plate 34 attached thereto also rotates, the outflow hole 35 formed on one side surface of the box 32 is closed (see the side indicated by the phantom line in the enlarged view of FIG. 10).
At this time, the fluid that has flowed into the box 32 can be passed directly to the planting tube 12 side.

  On the other hand, when the lever 33 is erected, in order to block the fluid that the lid plate 34 has flowed into the box body 32 in conjunction with the lever 33 from passing to the planting tube body 12 side, Can flow out from the outflow hole 35 (see the side indicated by the solid line in the enlarged view of FIG. 10).

  Of course, the branch valve 31 may be a commercially available branch valve, or the planting tube 12 itself may have a branchable configuration.

In the correspondence between the above-described embodiment and the configuration of the present invention, the water absorption pump 13 of this embodiment corresponds to the fluid supply means of the present invention, and hereinafter, the stopper plate material similarly corresponds to the stopper member.
A reed corresponds to a plant, but the present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.
