Description

Technical Field

[0001] This utility model relates to the field of afforestation tools, and more specifically to a water-jet drilling planting device for cuttings of *Salix matsudana* in sandy areas. Background Technology

[0002] In today's world, desertification has become one of the most serious ecological and environmental problems directly threatening human survival and development. Unreasonable human activities, enormous population pressure, and the irrational use of water resources are all causes of desertification. Currently, 65% of the world's land area is desertified to varying degrees, and this trend continues to spread.

[0003] Due to harsh natural environmental conditions, afforestation in desert areas is costly and has a low survival rate. Existing afforestation technologies sometimes employ water-jetting and hole-drilling planting methods, such as CN109644770A, entitled "A Method for Rapid Water-Jet Planting of Willows Applicable to Desert Areas." This method utilizes intensive water use and deep-hole water storage, allowing drilling, irrigation, and planting to be completed in one continuous process, providing sufficient water for the planted willows and creating conditions for rooting and growth. This invention provides ample water during cutting propagation, ensuring successful germination, rooting, and growth, significantly improving the efficiency and survival rate of willow afforestation and contributing to the rapid restoration of vegetation in desert areas.

[0004] However, in actual use, when using rigid water pipes to flush and drill holes, water will continuously splash out of the hole, thus wetting the sand around the hole. This inevitably wets the workers' shoes, and wet shoes easily stick to the sand, increasing the weight on the shoes and making it more difficult for workers to walk on the sand. At the same time, workers need to stop frequently to clean the sand off their shoes, affecting the afforestation speed.

[0005] Therefore, how to provide a water-jetting and drilling planting device for cuttings of *Salix matsudana* in sandy areas that can reduce or avoid water splashing and wetting the shoes of workers is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a water-jetting and drilling planting device for cuttings of *Salix matsudana* in sandy areas. It can not only complete drilling and watering in one go, improving planting efficiency, but also cover the planting holes with a splash guard to prevent water from splashing out and wetting the workers' shoes, thus avoiding the inconvenience of moving on the sandy ground.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A water-jet planting device for propagating *Salix matsudana* cuttings in sandy soil includes:

[0009] A water jetting gun, which is connected to an external water pipe, is used to inject water into sand to create planting holes.

[0010] A fixing plate is installed on the water injection and drilling gun rod of the water drilling gun;

[0011] A spring is sleeved on the water injection and drilling gun rod, and one end of the spring is fixedly connected to the bottom end face of the fixing plate.

[0012] A splash guard is slidably fitted onto the water injection and drilling gun rod. The top end of the splash guard is fixedly connected to the other end of the spring. The opening of the splash guard can be inserted into the sand, thereby covering the planting hole.

[0013] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a water-jetting and drilling planting device for cuttings of *Salix matsudana* in sandy soil. When drilling, the worker holds a water-jetting gun and inserts the water-jetting gun rod into the sand, and inserts the opening of the splash guard into the sand. Under the resistance of the sand, the splash guard moves upward relative to the water-jetting gun rod, compressing the spring. Then, the water-jetting gun rod forms planting holes by the impact of water injection. At this time, during the water injection process, because the hole is located inside the splash guard, the water splashed out of the hole will be blocked by the splash guard, thereby reducing the risk of splashing water wetting the worker's shoes.

[0014] Furthermore, the edge of the cover opening has a cutting edge for insertion into the sand.

[0015] The beneficial effects of adopting the above technical solution are: it makes it easier to insert the splash guard into the sand, thereby forming a sealed protective barrier around the planting hole and avoiding the problem of water splashing when injecting water and drilling holes.

[0016] Furthermore, a limiting disc is fixed on the inner wall of the splash guard, and the limiting disc is slidably sleeved on the water injection and drilling gun rod.

[0017] The beneficial effects of adopting the above technical solution are: the limiting plate can slide on the water injection gun rod, improving the stability of the splash guard when moving up and down, and avoiding the problem of the splash guard being tilted and stuck when sliding up and down.

[0018] Furthermore, the fixing plate is fixed to the water injection and drilling gun rod, or the outer wall of the water injection and drilling gun rod has external threads, the middle part of the fixing plate has a threaded hole, and the threaded hole is screwed to the external threads.

[0019] The beneficial effects of adopting the above technical solution are: by connecting the fixing plate to the water injection drilling gun rod with a thread, the position of the fixing plate on the water injection drilling gun rod can be adjusted appropriately according to the drilling depth, thereby improving the convenience and practicality of use.

[0027] like Figures 1-2 As shown, this utility model embodiment discloses a water-jetting and hole-drilling planting device for cuttings of *Salix matsudana* in sandy soil, comprising:

[0028] Drilling water gun 1, which is connected to an external water pipe, is used to inject water into the sand to create planting holes.

[0029] Fixing plate 2 is installed on the water injection and drilling gun rod 11 of the drilling water gun 1;

[0030] Spring 3 is sleeved on the water injection and drilling gun rod 11, and one end of it is fixedly connected to the bottom end face of the fixing plate 2.

[0031] The splash guard 4 is slidably mounted on the water injection and drilling gun rod 11. The top end of the splash guard 4 is fixedly connected to the other end of the spring 3. The opening 41 of the splash guard 4 can be inserted into the sand, thereby covering the planting hole.

[0032] Of course, in order to facilitate better insertion of the splash guard 4 into the sand, the edge of the opening 41 has an insertion blade 411 for insertion into the sand.

[0033] In some embodiments, a limiting disk 5 is fixed on the inner wall of the splash shield 4, and the limiting disk 5 is slidably sleeved on the water injection and drilling gun rod 11.

[0034] In some embodiments, the fixing plate 2 is fixed to the water injection and drilling gun rod 11, or the outer wall of the water injection and drilling gun rod 11 has external threads, and the middle part of the fixing plate 2 has a threaded hole 21, which is screwed to the external threads.

[0035] This planting device utilizes a water source with a certain pressure provided by a landscaping irrigation truck, specifically by connecting the water pump outlet of the irrigation truck to the inlet of the perforated water gun 1 via a water pipe. To reduce the pressure of the water pump from the irrigation truck, a T-junction can be added, dividing the outlet into 2-3 outlets, allowing 2-3 people to work simultaneously. Preferably, the water injection perforation gun rod 11 is a rigid plastic pipe or a galvanized water pipe, with a diameter of DN20 or DN25 and a length of approximately 90cm-140cm, preferably 140cm. The water pipe can also be a flexible plastic hose, with its length depending on the requirements, generally around 100mm.

[0036] The mounting plate can be made of stainless steel, galvanized steel, or rigid plastic sheet, and the splash guard can also be made of stainless steel, galvanized steel, or rigid plastic sheet, both approximately 2mm thick. The size of the mounting plate and splash guard can be customized according to the actual processing requirements.

[0037] In addition, the water jet gun 1 is a commercially available product with a built-in valve, or a valve can be added to a suitable position on the upper part of the water jet gun rod 11. This allows for convenient control of the water volume through the valve, thus saving water.

[0038] Yellow willow (Salix matsudana) is a perennial shrub belonging to the genus Salix of the family Salicaceae. It is characterized by its cold resistance, sand burial tolerance, and wind and sand resistance, and is often used in desertification control and ecological restoration. When using this drilling device, workers hold a water-jetting gun and insert the water-jetting gun rod into the sand, while also inserting the opening of the splash guard into the sand. Due to the resistance of the sand, the splash guard moves upward relative to the water-jetting gun rod, compressing a spring. The compressed spring exerts a downward force on the splash guard, causing the opening of the splash guard to be fully inserted into the sand. Then, the water-jetting gun rod uses the impact of water injection to create planting holes. During the water injection process, because the holes are located inside the splash guard, the water splashing out of the holes is blocked by the splash guard, thus reducing the risk of splashing water onto the workers' shoes.

[0039] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
