Description

Technical Field

[0001] This utility model relates to the technical field of tree transplantation, digging, felling or pruning, and in particular to a three-dimensional water replenishment high-pressure water spraying device for sandy land afforestation. Background Technology

[0002] The standard procedure for transplanting trees is to dig a planting hole, place the tree in the hole, water the hole, and then backfill the hole after the water has seeped into the soil. After backfilling, a basin is left to collect rainwater and facilitate subsequent watering (it takes time for water to seep into the soil, so filling the basin with water and letting it slowly seep in is the mainstream watering method after transplanting trees).

[0003] Transplanting trees in sandy soil (specifically in arid regions) differs significantly from transplanting trees into conventional land. Tree basins are no longer needed because there is no rainwater to collect, nor is there a need for slow infiltration (water infiltrates quickly). Conversely, tree basins are less wind-resistant. When watering trees in sandy soil, care must be taken to avoid water flowing on the surface or wetting the topsoil, which would lead to ineffective evaporation.

[0004] For transplanting trees in sandy soil, the most suitable watering method is not surface watering, but rather injecting water directly into the ground, similar to grouting. This completely avoids water flowing on the surface and prevents wetting the topsoil. However, there are currently no irrigation tools that can achieve this. Grouting equipment such as steel pipes used in civil engineering cannot be used directly for watering. Current surface-based watering methods cannot prevent water from flowing on the surface or evaporating ineffectively.

[0005] However, directly inserting a water pipe into the sand for watering presents another problem: the injected water will seep vertically into the deep sand instead of wetting the surrounding soil around the tree roots. Furthermore, if multiple outlets are used in different directions, for a high-speed flowing fluid, since its pressure is primarily dynamic rather than static, the total pressure (the sum of dynamic and static pressure) in front of the flow direction is high, while the total pressure on the sides (which only includes static pressure, not dynamic pressure) is very low, possibly even negative (as with a Venturi tube). This phenomenon means that if a pipe spraying water at high speed has an opening on the side, almost no water will spray out, and there is even a possibility of backflow. Utility Model Content

[0006] This invention provides a high-pressure water spraying device for three-dimensional water replenishment in sandy land afforestation.

[0007] The technical problem to be solved is that when watering trees in sandy soil, it is important to avoid water flowing on the surface or wetting the topsoil, which would cause ineffective evaporation. However, current surface watering methods cannot avoid this.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a three-dimensional water replenishment sand afforestation high-pressure water spraying device, including a hollow drill rod connected to the water pump outlet of a water supply truck through a connecting pipe, a water switch is provided at the junction of the hollow drill rod and the connecting pipe, a downward nozzle for spraying water downward is provided at the lower end of the hollow drill rod, and transverse water spraying holes are spaced apart on the lower side for spraying water horizontally in all directions after the downward nozzle is inserted into the sand and the outflow resistance increases. The transverse water spraying holes are arranged in multiple vertical columns on the hollow drill rod. The downward nozzle is fitted with a soil compaction ring for compacting the sand to ensure that the horizontal water spray hole can spray water and to squeeze out space for the horizontal water spray hole. The soil compaction ring is a metal ring with an outer diameter larger than the outer diameter of the hollow drill rod and is fixedly connected to the downward nozzle. The hollow drill rod is also fitted with a protective sleeve to prevent the horizontal water spray hole from being exposed to the air after the downward nozzle is inserted into the sand and the outflow resistance increases when water is first added. The protective sleeve is slidably fitted on the hollow drill rod.

[0009] Furthermore, both the hollow drill rod and the protective sleeve are stainless steel pipes. The length of the protective sleeve is at least four centimeters longer than the distance between the downward nozzle and the uppermost horizontal water spray hole. The bottom of the protective sleeve has a horizontal anchor to prevent the protective sleeve from entering the soil. The anti-soil-entry barrier extends to the left and right sides of the downward nozzle and blocks the hole punched out by the soil-pressing ring after the downward nozzle enters the soil.

[0010] Furthermore, the upper end of the protective sleeve is equipped with an anti-loosening spring for pressing the protective sleeve and the anti-soil-entry barrier tightly onto the sand. The anti-loosening spring is sleeved on the hollow drill rod, with its lower end welded to the protective sleeve and its upper end tied to the water switch.

[0011] Furthermore, the transverse water jet holes are arranged in four vertical columns on the hollow drill rod, and the four vertical columns are evenly distributed around the hollow drill rod.

[0012] Furthermore, the water switch is a trigger switch, and the connecting pipe is an explosion-proof flexible hose.

[0013] Furthermore, the soil-pressing ring is a brass ring integrally formed with the downward nozzle.

[0014] Compared with existing technologies, the high-pressure water spraying device for three-dimensional water replenishment in sandy land has the following advantages: In this invention, a hollow drill rod inserted into the sand is used to water the trees in a manner similar to grouting. A soil-pressing ring is used to bury the downward nozzle in the compacted sand, while the horizontal water spray outlet on the side of the hollow drill rod is not blocked by the sand. This reduces the water flow velocity sprayed forward (i.e. downward) from the hollow drill rod, and decreases the proportion of static pressure in the water pressure in the pipe (because the dynamic pressure decreases, while the pressure provided by the water source remains unchanged). This allows water to spray from the horizontal water spray outlet, so that the water injected into the sand can moisten a large area of ​​sand around the tree roots, rather than seeping vertically into the depths.

Detailed Implementation

[0016] Taking the afforestation project at the Yuli Bayingolin Desertification Control Station as an example, such as Figure 1-3 As shown, a three-dimensional water replenishment high-pressure water spraying device for afforestation in sandy areas includes a hollow drill rod 1 connected to the water pump outlet of a tracked water supply vehicle (to ensure movement in the desert) via a connecting pipe 4. A water switch 3 is provided at the junction of the hollow drill rod 1 and the connecting pipe 4. A downward nozzle 5 for spraying water downward is provided at the lower end of the hollow drill rod 1, and transverse water spraying holes 6 are provided at intervals on the lower side for spraying water horizontally in all directions after the downward nozzle 5 is inserted into the sand and the outflow resistance increases. The transverse water spraying holes 6 are arranged in multiple vertical columns on the hollow drill rod 1. The horizontal water jet 6 here can basically not spray water when there is no obstruction at the front end of the downward nozzle 5. It can only spray water when the downward nozzle 5 is buried in sand.

[0017] The downward nozzle 5 is fitted with a soil compaction ring 2 for compacting the sand to ensure that the transverse water spray hole 6 can spray water and to squeeze out space for the transverse water spray hole 6. The soil compaction ring 2 is a metal ring with an outer diameter larger than the outer diameter of the hollow drill rod 1, and is fixedly connected to the downward nozzle 5. Here, the soil-pressing ring 2 ensures that after the hollow drill rod 1 is vertically inserted into the sand, the area below the downward nozzle 5 is compacted sand, slowing down the water flow. At the same time, its shape also squeezes out a small channel in the sand, which, together with the downward impact of the water flow, ensures that the outlet of the horizontal water jet 6 is not blocked by sand and is not easily clogged by sand.

[0018] The hollow drill rod 1 is also fitted with a protective sleeve 7 to prevent the horizontal water spray hole 6 from being exposed to the air after the downward nozzle 5 is inserted into the sand and the outflow resistance increases when water is first added. The protective sleeve 7 is slidably fitted on the hollow drill rod 1.

[0019] The protective sleeve 7 is an easily overlooked structure. Water should not be sprayed only after the hollow drill pipe 1 has been inserted deep into the formation. For efficiency and to wet soil at different depths, in actual operation, the drill rod 1 needs to be inserted into the sand after the water switch 3 is turned on, and then inserted deeper while spraying water. During the insertion process, for a period of time, the downward nozzle 5 at the front end of the hollow drill rod 1 is buried in the compacted sand, while the horizontal water spray hole 6 is exposed to the air. At this time, the horizontal water spray hole 6 will spray water into the surrounding air, which not only wastes water and makes the ground muddy, but also wets the operator's clothes.

[0020] In this embodiment, both the hollow drill rod 1 and the protective sleeve 7 are stainless steel pipes. The length of the protective sleeve 7 is at least four centimeters longer than the distance between the downward nozzle 5 and the uppermost horizontal water spray hole 6. The bottom horizontal anchor of the protective sleeve 7 is a soil-proof barrier 9 used to prevent the protective sleeve 7 from entering the soil. The soil-proof barrier 9 extends to the left and right sides of the downward nozzle 5 and blocks the hole punched out by the soil-pressing ring 2 after the downward nozzle 5 enters the soil.

[0021] The upper end of the protective sleeve 7 is equipped with an anti-loosening spring 8 for pressing the protective sleeve 7 and the anti-soil-entry stop bar 9 tightly onto the sand. The anti-loosening spring 8 is sleeved on the hollow drill rod 1, with its lower end welded to the protective sleeve 7 and its upper end tied to the water switch 3.

[0022] Water is easily splashed out at the front end of the hollow drill rod 1 during operation, and the contact area contains a lot of wet sand, mud, and dirty water. This makes it unsuitable to hold the protective sleeve 7 by hand, as it would force the operator to bend over and would also wet and soil their clothes and body. Therefore, an anti-loosening spring 8 is used to connect the protective sleeve 7 remotely, ensuring that the protective sleeve 7 remains on the ground surface as the hollow drill rod 1 is inserted into the soil.

[0023] The transverse water jet holes 6 are arranged in four vertical columns on the hollow drill rod 1, and the four columns are evenly distributed around the circumference of the hollow drill rod 1. Of course, more transverse water jet holes 6 can be set, but four columns can ensure the effect while reducing the processing difficulty.

[0024] In this embodiment, the water switch 3 is a trigger switch, which facilitates outdoor operation. The connecting pipe 4 is an explosion-proof flexible hose, which ensures a smooth flow path during bending.

[0025] In this embodiment, the downward nozzle 5 is made of brass, therefore the soil-pressing ring 2 is a brass ring integrally formed with the downward nozzle 5 (brass is not easy to weld). If the downward nozzle 5 is made of steel, the soil-pressing ring 2 can be welded to the downward nozzle 5.

[0026] This utility model discloses a three-dimensional water replenishment high-pressure water spraying device for afforestation in sandy areas, the method of using which includes the following steps: Step 1: Drive the water truck with the water tank filled with water to the vicinity of the trees that need watering; Step 2: Push the hollow drill rod 1 against the side of the tree so that the anti-soil barrier 9 is pressed against the ground surface; Step 3: Turn on water switch 3, and then gradually press the hollow drill rod 1 deep into the soil.

[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
