Description

Technical Field

[0001] This utility model belongs to the field of seedling irrigation technology, specifically a seedling irrigation device for forestry engineering. Background Technology

[0002] Forestry engineering is a comprehensive discipline that uses engineering technology to cultivate, develop and utilize forest resources and process forest products, based on the principles of forest resource utilization and sustainable development, in order to achieve the sustainable use of forest resources.

[0003] During the seedling growth process, water is sprayed onto the seedlings to promote their healthy growth and improve their survival rate. The seedling irrigation device mainly uses a high-pressure water pump to pressurize the water, which is then transported to the nozzles through the pipeline system. The pressurized water is then sprayed into a fine mist through the nozzles onto the seedling canopy and soil surface, thus simulating natural rainfall.

[0004] Traditional irrigation devices typically have sprinklers fixed to vertical pipes, making it difficult for adjacent sprinklers to effectively overlap their spray ranges. This can lead to missed areas, resulting in insufficient irrigation in some areas or irrigation exceeding the designated plot area, making it difficult to irrigate evenly.

[0005] Therefore, this utility model provides a seedling irrigation device for forestry engineering. Utility Model Content

With the above structure, forestry irrigation water containing silt and fine particulate impurities can directly enter the water tank for irrigation of seedlings, leading to equipment and nozzle blockage. The quickly installable and removable filter cotton can effectively remove suspended solids in the water, reducing the problem of shortened irrigation spray range or decreased atomization effect due to impurity accumulation. Furthermore, when the filter cotton becomes clogged after long-term use, it can be quickly replaced, reducing downtime during cleaning and minimizing efficiency loss.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown, an embodiment of the present invention provides a seedling irrigation device for forestry engineering, comprising a base 1; a plurality of casters 10 are mounted on the bottom of the base 1; a water tank 12 is fixedly connected to the top of the base 1; a connecting pipe 11 is connected to the side wall of the water tank 12; a filter assembly 3 is installed in the middle of the connecting pipe 11; a water pump 13 is installed on the top of the water tank 12; the water pump 13 is installed inside the water tank 12; a first protective cover 18 is fixedly connected to the outside of the water pump 13; a water suction pipe 14 is fixedly connected to the middle of the water pump 13; a drain pipe 15 is fixedly connected to the end of the water pump 13; the middle of both the drain pipe 15 and the water suction pipe 14 penetrates the middle of the first protective cover 18; the end of the drain pipe 15 penetrates the top of the water tank 12; a rotating assembly 2 is fixedly connected to the top of the water tank 12; two rotating components are installed in the middle of the rotating assembly 2. Sprayer head 16; two spray heads 16 are arranged opposite each other; a filter screen 17 is fixedly connected to the end of the spray head 16; the rotating assembly 2 includes a fixed base 21; the fixed base 21 is fixedly connected to the top of the water tank 12; a rotating plate 22 is rotatably connected to the middle of the fixed base 21; a first bevel gear 23 is fixedly connected to the outer wall of the rotating plate 22; the first bevel gear 23 is located at the bottom of the rotating plate 22; a second bevel gear 24 is meshed with the middle of the first bevel gear 23; a motor 25 is fixedly connected to the middle of the second bevel gear 24; the output end of the motor 25 passes through the middle of the fixed base 21; a second protective cover 26 is fixedly connected to the top of the water tank 12; the second protective cover 26 is fixedly connected to the outside of the motor 25; two adjusting assemblies 4 are installed in the middle of the rotating plate 22; a water outlet pipe 27 is installed in the middle of the adjusting assembly 4. A first sealing ring 28 is fixedly connected to the end of the water outlet pipe 27; the nozzle 16 is fixedly connected to the end of the water outlet pipe 27; during operation, the irrigation pipe is connected to the end of the connecting pipe 11, and the water flows through the connecting pipe 11 into the filter assembly 3 for filtration. The filtered water enters the water tank 12, which stores some water. Before irrigating the seedlings, the distance between the two nozzles 16 is quickly adjusted by the adjusting assembly 4, and the water pump 13 is turned on. The water in the water tank 12 is pumped into the drain pipe 15 through the pumping pipe 14. The first protective cover 18 protects the water pump 13. At this time, the water flows into the fixed base 21, and the control system turns on the motor 25. The output end of the motor 25 drives the second bevel gear 24 to rotate. The second bevel gear 24 drives the first bevel gear 23 to rotate the rotating plate 22 in the middle of the fixed base 21. After the water flows into the two water outlet pipes 27, it is discharged from the end of the nozzle 16. After passing through the filter screen 17, external impurities are intercepted and enter the interior of the nozzle 16. As the rotating plate 22 rotates, the sprayed water is evenly distributed to the irrigation area. Through the above structure, the nozzle 16 can rotate continuously when irrigating the seedlings. It can evenly distribute the water to the surrounding area through centrifugal force, so that the water flow is distributed in a spiral shape around the seedlings. This reduces the problem of local areas being too wet or too dry due to fixed spray irrigation of the nozzle 16, reduces irrigation blind spots, and makes the spraying area form an effective superposition and complement, thereby expanding the overall irrigation coverage area and enabling the seedlings to be fully irrigated.

[0025] like Figure 1 , Figure 2 , Figure 5 As shown, the filter assembly 3 includes a filter box 31; the filter box 31 is fixedly connected to the middle of the connecting pipe 11; the filter box 31 is fixedly connected to the side wall of the water tank 12; two mounting boxes 32 are fixedly connected to the middle of the filter box 31; two through slots 33 are opened in the middle of the mounting box 32; the two through slots 33 are located on both sides of the mounting box 32; multiple elastic plates 34 are fixedly connected to the middle of the through slots 33; filter cotton 35 is installed in the middle of the mounting box 32; a sealing groove 36 is opened on the top of the filter box 31; a box cover 38 is installed in the middle of the sealing groove 36; a sealing strip 37 is fixedly connected to the middle of the box cover 38; the sealing strip 37 is installed inside the corresponding sealing groove 36; during operation, the box cover 38 is opened, and then the filter cotton 35 is placed in the middle of the mounting box 32. When the filter cotton 35 enters the mounting box 32, it applies pressure to the multiple elastic plates 34 on both sides, causing the elastic plates 34 to bend elastically. At this time, the filter cotton 35 is clamped and fixed by the elastic plates 34 on both sides, and the filter cotton 35 is quickly installed in the mounting box 31. 2. In the middle section, after the filter cotton 35 is installed, the box cover 38 is installed on the top of the filter box 31. At this time, the sealing strip 37 enters the sealing groove 36 and seals the inside of the filter box 31 through the sealing strip 37. After the irrigation water flows into the filter box 31 through the connecting pipe 11, it passes through the two filter cottons 35 to intercept particulate impurities in the water flow, allowing pure water to enter the water tank 12. After the filter cotton 35 has been used for a period of time, it can be quickly removed for cleaning or replacement. Through the above structure, the forestry irrigation water source contains silt and broken particulate impurities. If it directly enters the water tank 12 to irrigate the seedlings, it will cause the equipment and nozzles 16 to become clogged. The filter cotton 35, which can be quickly installed and removed, can effectively remove suspended solids in the water, reducing the problem of shortened irrigation spray range or reduced atomization effect caused by the accumulation of impurities. Furthermore, when the filter cotton 35 becomes clogged after long-term use, it can be quickly replaced, reducing the downtime during cleaning and thus reducing efficiency.

[0026] like Figure 3 and Figure 4As shown, the adjustment assembly 4 includes two fixed pipes 41; the two fixed pipes 41 are arranged opposite each other; the two fixed pipes 41 are fixedly connected to the middle of the rotating plate 22; two sliding grooves 42 are opened on the inner side wall of the fixed pipes 41; multiple positioning grooves 43 are opened on the side wall of the sliding grooves 42; the multiple positioning grooves 43 are equidistantly distributed; the water outlet pipe 27 is slidably and rotatably connected to the middle of the fixed pipes 41; two positioning blocks 44 are fixedly connected to the end of the water outlet pipe 27; the two positioning blocks 44 are set at the corresponding sliding grooves 42; when adjusting the distance between the two nozzles 16, the water outlet pipe 27 is first slid in the middle of the base 1, and then... Positioning block 44 limits the water outlet pipe 27. Positioning block 44 slides in the middle of slide groove 42. When water outlet pipe 27 moves to the designated position, water outlet pipe 27 is rotated so that positioning block 44 enters the middle of the corresponding positioning groove 43, thereby fixing the position of water outlet pipe 27 and quickly adjusting the distance between the two nozzles 16. The above structure can flexibly adjust the distance between the two nozzles 16 in the seedling stage or in high-density planting areas, so that the roots of seedlings at different times can be evenly covered, reducing uneven irrigation caused by different spacing between seedlings, thereby controlling the size of the irrigation overlap area.

[0027] like Figure 4 As shown, a rotating ring 5 is rotatably connected to the end of the nozzle 16; a scraper 51 is fixedly connected to the middle of the rotating ring 5; the end of the scraper 51 is in contact with the filter screen 17; a rotating shaft 52 is fixedly connected to the middle of the scraper 51; a diverting rod 53 is rotatably connected to the middle of the rotating shaft 52; during operation, after the nozzle 16 has been used for a period of time, the rotating ring 5 is rotated to make it rotate at the end of the nozzle 16. As the rotating ring 5 rotates, the scraper 51 scrapes away the impurities intercepted in the middle of the filter screen 17. According to the spraying requirements, the diverting rod 53 can be rotated to cross the position of the scraper 51, so that the water flow is diverted and sprayed. Through the above structure, the impurities intercepted by the filter screen 17 can be scraped away after irrigation, reducing the accumulation of impurities such as mud and sand on the surface of the filter screen 17 and causing blockage. In addition, the cross distribution of the diverting rod 53 and the scraper 51 can make the water flow cross-distributed to maintain the uniform water volume in the irrigation area.

[0028] like Figure 3 As shown, a sealing plate 6 is fixedly connected to the top of the water tank 12; the sealing plate 6 is rotatably connected to the bottom of the rotating plate 22; two second sealing rings 61 are fixedly connected to the bottom of the rotating plate 22; the two second sealing rings 61 are fixedly connected to both sides of the sealing plate 6; during operation, when the motor 25 drives the first bevel gear 23 to rotate, the bottom of the rotating plate 22 rotates on the top of the sealing plate 6. When water flows into the interior of the rotating plate 22, the two second sealing rings 61 seal the space between the sealing plate 6 and the rotating plate 22. The above structure can effectively reduce the direct contact between the water flow and the first bevel gear 23 and the second bevel gear 24, and reduce the corrosion problem of the first bevel gear 23 and the second bevel gear 24 under long-term use.

[0029] like Figure 1As shown, an observation plate 7 is fixed to the side wall of the water tank 12; the observation plate 7 is transparent; when water flows into the water tank 12 for storage during operation, the water storage volume inside the water tank 12 can be directly observed through the observation plate 7. Through the above structure, the accumulation of impurities inside the water tank 12 after long-term use can be directly observed, and the inside of the water tank 12 can be cleaned in a timely manner.

[0030] During operation, the irrigation pipe is connected to the end of the connecting pipe 11. Water flows through the connecting pipe 11 and enters the filter assembly 3 for filtration. The filtered water enters the water tank 12, which stores some water. Before irrigating the seedlings, the distance between the two nozzles 16 is quickly adjusted using the adjusting assembly 4, and the water pump 13 is turned on. Water is drawn from the water tank 12 through the pumping pipe 14 and discharged into the drain pipe 15. The first protective cover 18 protects the water pump 13. At this time, the water flows into the fixed base 21, and the control system turns on the motor 25. The output end of the motor 25 drives the second bevel gear 24 to rotate. The second bevel gear 24 drives the first bevel gear 23 to rotate the plate 2. 2. Rotate the fixed base 21 in the middle. Water flows into the two outlet pipes 27 and is discharged from the end of the nozzle 16. After passing through the filter screen 17, external impurities are intercepted and enter the nozzle 16. As the rotating plate 22 rotates, the sprayed water is evenly distributed to the irrigation area. Open the box cover 38 and place the filter cotton 35 in the middle of the mounting box 32. When the filter cotton 35 enters the mounting box 32, it applies pressure to the multiple elastic plates 34 on both sides. The elastic plates 34 bend elastically. At this time, the filter cotton 35 is clamped and fixed by the elastic plates 34 on both sides. Quickly install the filter cotton 35 in the middle of the mounting box 32. After the filter cotton 35 is installed, install the box cover 38 on the top of the filter box 31. At this time, the sealing strip 37 enters the sealing groove 36. The filter box 31 is sealed by a sealing strip 37. Irrigation water enters the filter box 31 through the connecting pipe 11 and passes through two filter cottons 35 to intercept particulate impurities in the water flow, allowing pure water to enter the water tank 12. After the filter cottons 35 have been used for a period of time, they can be quickly removed for cleaning or replacement. When adjusting the distance between the two nozzles 16, the water outlet pipe 27 is first slid in the middle of the base 1. The positioning block 44 limits the water outlet pipe 27 and slides in the middle of the slide groove 42. After the water outlet pipe 27 moves to the designated position, the water outlet pipe 27 is rotated so that the positioning block 44 enters the middle of the corresponding positioning groove 43, thereby fixing the position of the water outlet pipe 27. The distance between the two nozzles 16 can be quickly adjusted. After the nozzles 16 have been used for a period of time, the rotating ring 5 is rotated to make it rotate at the end of the nozzles 16. As the rotating ring 5 rotates, the scraper 51 scrapes away the impurities intercepted in the middle of the filter screen 17. According to the spraying requirements, the diverting rod 53 can be rotated to cross the position of the scraper 51 so that the water flow is diverted and sprayed. When the motor 25 drives the first bevel gear 23 to rotate, the bottom of the rotating plate 22 rotates on the top of the sealing plate 6. When the water flow enters the interior of the rotating plate 22, the sealing plate 6 and the rotating plate 22 are sealed by the two second sealing rings 61. When the water flow enters the interior of the water tank 12 for storage, the water storage level inside the water tank 12 can be directly observed through the observation plate 7.
