Description

Technical Field

[0001] This invention belongs to the field of seedling cultivation technology, specifically relating to an intelligent irrigation device for cultivating forest seedlings. Background Technology

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of trees to play a protective role. In the human and biosphere, forestry engages in the cultivation, protection and utilization of forest resources through advanced science and technology and management methods, fully utilizes the multiple benefits of forests, and sustainably manages forest resources to promote the coordinated development of population, economy, society, environment and resources. In forestry seedling cultivation activities, water is often needed to irrigate the seedlings in the seedbed.

[0003] Existing seedling cultivation devices require manual, irregular irrigation of seedlings, making it difficult to control the amount of water used, which can easily lead to water waste. Seedlings that do not receive timely irrigation may dry out, resulting in poor development or even death. In addition, after a certain period of irrigation, the soil around the seedlings may become compacted and hard, which can affect the subsequent growth of the seedlings.

[0004] To address the aforementioned issues, this application proposes an intelligent irrigation device for cultivating forest seedlings. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides an intelligent irrigation device for forest seedling cultivation. As water evaporates from the cultivation chamber, the device moves upwards under the influence of a counterweight and brine, allowing water to flow directly to the seedling roots through connecting pipes, control pipes, slow-flow pipes, pre-embedded pipes, and multiple seepage points on the surface of the pre-embedded pipes. This ensures the seedlings receive the necessary water for normal growth, achieving quantitative water injection and preventing water waste. The process requires no manual intervention, exhibiting a high degree of automation. It prevents seedlings from drying out, developing poorly, or even dying due to insufficient irrigation. A toothed soil-loosening cone loosens the surface layer of the cultivation soil, preventing surface moisture loss and hardening of the soil, thus ensuring normal seedling growth.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent irrigation device for cultivating forest seedlings, comprising a cultivation box;

[0019] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0020] 1. By setting up a self-checking upward movement component, and through the coordinated use of the set counterweight, culture chamber, guide wheel, and pull rope, the appropriate counterweight can be selected according to the overall mass of the culture chamber in the initial state. The counterweight is connected to one end of the pull rope. As the water in the culture chamber evaporates, the overall weight of the culture chamber becomes lighter. At this time, the counterweight can lift the culture chamber through the set pull rope and guide wheel, so that the culture chamber moves slowly upward in the incubator.

[0021] At the same time, a certain concentration of saline solution is injected into the internal cavity of the incubator, so that the incubator floats on the surface of the saline solution. At this time, the buoyancy of the saline solution and the pulling force of the counterweight are equal to the overall weight of the incubator, so as to ensure that the incubator can be stably suspended inside the incubator in the initial state. As the water in the incubator evaporates, the incubator can move upward inside the incubator under the action of the buoyancy of the saline solution and the pulling force of the counterweight.

[0022] 2. By setting up an automatic watering component, and through the coordinated use of connecting pipes, control pipes, water leakage channels, diversion channels, and control lifting rods, the diversion channels on the surface of the control pipes and the water leakage channels in the connecting pipes can be connected as the cultivation chamber moves upward. At this time, the water in the water tank can flow into the cultivation chamber through the connecting pipes and control pipes, which can automatically irrigate the seedlings in the cultivation chamber without human intervention. The process is highly automated and avoids the seedlings from not receiving timely irrigation, which can lead to seedling drying out, poor seedling development, or even death.

[0023] By setting up a slow-flow pipe, the water in the water tank can flow into the slow-flow pipe in advance when it flows down through the connecting pipe and the control pipe. With the slow-flow pipe set in a spiral structure, it is ensured that the water needs a certain amount of time to flow into the pre-embedded pipe through the slow-flow pipe, so as to ensure that enough water is injected into the culture chamber.

[0024] When the water in the cultivation chamber evaporates, it can move upward under the action of the counterweight and salt water, and allow the water to flow directly to the roots and stems of the seedlings through the connecting pipe, control pipe, slow-flow pipe, and pre-buried pipe, as well as multiple seepage holes on the surface of the pre-buried pipe, to ensure the normal water requirements for seedling growth. It can achieve quantitative water injection and irrigation, and avoid water waste.

[0025] 3. By setting up an automatic sprinkler assembly, through the coordinated use of structures such as a fixed rod, rotating sleeve, connecting rod, piston, and drainage telescopic tube, when water flows out through the connecting pipe and control pipe, some water can be stored in the sprinkler pipe through the drainage telescopic tube and rotary joint. At the same time, air can enter the cavity inside the rotating sleeve. After the cultivation chamber moves down, the air entering the cavity inside the rotating sleeve can be compressed through the air pipe to the position below the partition, and the gas can pressurize the sprinkler pipe that has been pre-entered. The sprinkler pipe can spray the outside of the seedling in a ring shape to ensure all-round irrigation of the seedling.

[0026] When the L-shaped connecting plate on the outside of the rotary joint rotates, the toothed soil loosening cone installed on the bottom of the L-shaped connecting plate can loosen the surface layer of the potting soil, preventing the surface soil from hardening after the loss of surface moisture, thus ensuring the normal growth of seedlings.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example: Figures 1-11 As shown, the present invention provides a technical solution: an intelligent irrigation device for cultivating forest seedlings, including a cultivation box 1;

[0044] The incubator 1 is equipped with a self-inspection upward moving component 2, which includes a counterweight 21, a culture chamber 22, a pre-embedded pipe 23, a guide column 24, a pulley 25, a hanger 26, a connecting rod 27, a guide wheel 28, and a pull rope 29.

One end of the pull rope 29 is connected to the hanger 26, and the other end of the pull rope 29 is connected to a counterweight 21 set on the outside of the incubator 1.

[0046] A guide post 24 is fixed to the side of the culture chamber 22. One end of the guide post 24 is rotatably connected to a pulley 25. The pulley 25 is slidably connected in a strip groove opened on the surface of the incubator 1, which can ensure the stability of the culture chamber 22 during the upward movement.

[0047] The culture chamber 22 is equipped with a pre-embedded pipe 23, and the surface of the pre-embedded pipe 23 is provided with multiple water seepage holes. The surface of the culture chamber 22 is fixedly installed with an abutment rod 27.

[0048] A certain concentration of saline solution is injected into the internal cavity of the incubator 1, which makes it easy for the culture chamber 22 to float on the surface of the saline solution. The buoyancy of the saline solution and the pulling force of the counterweight 21 are equal to the overall weight of the culture chamber 22, so as to ensure that the culture chamber 22 can be stably suspended inside the incubator 1 in the initial state.

[0049] The incubator 1 is equipped with an automatic water injection component 3, which includes a water tank 31, a connecting pipe 32, a control pipe 33, a guide rod 34, a spring 35, a water leakage groove 36, a diversion groove 37, a slow flow pipe 38, a control lifting rod 39, and a mounting plate 310.

[0050] A water tank 31 is installed on the surface of the incubator 1. A connecting pipe 32 is connected to the bottom of the water tank 31. A control pipe 33 slides inside the bottom end of the connecting pipe 32. A guide rod 34 slides inside a blind hole on the surface of the control pipe 33. One end of the guide rod 34 is fixed inside the bottom end of the connecting pipe 32. A spring 35 is sleeved on the outside of the guide rod 34. A water leakage groove 36 is opened inside the connecting pipe 32. A drainage groove 37 that matches the water leakage groove 36 is opened on the surface of the control pipe 33. A control lifting rod 39 is fixedly installed on the outside of the control pipe 33.

[0051] An installation plate 310 is fixedly installed on the inner wall of the incubator 1. A slow-flow pipe 38 is installed on the surface of the installation plate 310. The slow-flow pipe 38 is arranged in a spiral structure, and one end of the slow-flow pipe 38 is sleeved on the outside of the control pipe 33. The other end of the slow-flow pipe 38 is inserted into the pre-embedded pipe 23 to ensure that the water flows through the slow-flow pipe 38 into the pre-embedded pipe 23 for a certain period of time, so as to ensure that sufficient water is injected into the incubator 22.

[0052] An automatic spraying assembly 4 is fixed on the surface of the culture chamber 22. The automatic spraying assembly 4 includes a fixed rod 41, a rotating sleeve 42, a spiral groove 43, a sliding protrusion 44, a connecting rod 45, a piston 46, a rotary joint 47, a drainage telescopic tube 48, a spraying pipe 49, an L-shaped fixing frame 410, an L-shaped connecting plate 411, a toothed loosening cone 412, a limiting bolt 413, a partition 414, and an air pipe 415.

[0053] An L-shaped fixing frame 410 is fixedly installed on the surface of the culture chamber 22. A rotary joint 47 is rotatably connected to the surface of the L-shaped fixing frame 410. A drainage telescopic tube 48 is connected to the outside of the rotary joint 47. One end of the drainage telescopic tube 48 is connected to the control tube 33. An L-shaped connecting plate 411 is fixed to the bottom outside of the rotary joint 47. A spray pipe 49 is fixed to one side of the L-shaped connecting plate 411 by a pipe clamp. One end of the spray pipe 49 is connected to the rotary joint 47.

[0054] A fixing rod 41 is fixed on the inner top surface of the incubator 1. A rotating sleeve 42 is slidably connected to the outer side of the fixing rod 41. A sliding protrusion 44 is fixed on the inner wall of one end of the rotating sleeve 42. The sliding protrusion 44 is slidably connected in the spiral groove 43 opened on the surface of the fixing rod 41. The other end of the rotating sleeve 42 is connected to the rotary joint 47.

[0055] A partition plate 414 is fixed inside the rotating sleeve 42. A connecting rod 45 is fixed to one end of the fixing rod 41.

A toothed soil loosening cone 412 is fixed to the bottom end of the L-shaped connecting plate 411. A limit bolt 413 is threadedly connected to the surface of the L-shaped fixing frame 410. One end of the limit bolt 413 abuts against the groove opened on the surface of the rotary joint 47. The limit bolt 413 can ensure the smooth rotation of the rotary joint 47 on the surface of the L-shaped fixing frame 410. The main function of the limit bolt 413 is to limit the rotation of the rotary joint 47. One end of the limit bolt abuts against the groove opened on the surface of the rotary joint 47, but it is not abutting and fixing. It can ensure that the sliding of one end of the limit bolt 413 in the groove opened on the surface of the rotary joint 47 is not affected.

[0056] The working principle and usage process of this invention are as follows: When in use, first pour the cultivation soil into the cultivation chamber 22, place the pre-embedded pipe 23 into the cultivation chamber 22, plant the seedling in the cultivation chamber 22, inject a certain amount of water into the cultivation chamber 22, and select a corresponding counterweight 21 according to the overall weight of the cultivation chamber 22 at this time. Connect the counterweight 21 to one end of the pull rope 29. As the water in the cultivation chamber 22 evaporates, the overall weight of the cultivation chamber 22 becomes lighter. At this time, the counterweight 21 can lift the cultivation chamber 22 through the pull rope 29 and the guide wheel 28, so that the cultivation chamber 22 moves slowly upward in the cultivation box 1.

[0057] During the upward movement of the culture chamber 22, the stability of the culture chamber 22 can be ensured by the guiding action of the guide column 24 and pulley 25.

[0058] At the same time, a certain concentration of salt water is injected into the internal cavity of the incubator 1, so that the culture chamber 22 floats on the surface of the salt water. At this time, the buoyancy of the salt water and the pulling force of the counterweight 21 are equal to the overall weight of the culture chamber 22, so as to ensure that the culture chamber 22 can be stably suspended inside the incubator 1 in the initial state. As the water in the culture chamber 22 evaporates, the culture chamber 22 can move upward inside the incubator 1 under the action of the buoyancy of the salt water and the pulling force of the counterweight 21.

[0059] When the cultivation chamber 22 moves upward, the abutment rod 27 fixed on its surface moves upward until it contacts the control lifting rod 39. As the cultivation chamber 22 moves upward, one end of the abutment rod 27 pushes the control lifting rod 39 upward, causing the control lifting rod 39 to drive the control pipe 33 to slide into the connecting pipe 32 until the drainage groove 37 on the surface of the control pipe 33 connects with the water leakage groove 36 in the connecting pipe 32. At this time, the water in the water tank 31 can flow into the cultivation chamber 22 through the connecting pipe 32 and the control pipe 33, which facilitates automatic irrigation of the seedlings in the cultivation chamber 22. No manual intervention is required during this process, and the degree of automation is high. This avoids the seedlings not receiving timely irrigation, which could lead to seedling drying out, poor seedling development, or even death.

[0060] When the control pipe 33 slides into the connecting pipe 32, the guide rod 34 ensures the stability of the control pipe 33 during the upward movement and ensures the relative position of the drainage groove 37 on the surface of the control pipe 33 and the leakage groove 36 in the connecting pipe 32.

[0061] When the water in the water tank 31 flows down through the connecting pipe 32 and the control pipe 33, the water can flow into the slow-flow pipe 38 in advance. With the slow-flow pipe 38 in a spiral structure, it is ensured that the water needs a certain amount of time to flow into the pre-embedded pipe 23 after passing through the slow-flow pipe 38, so as to ensure that enough water is injected into the culture chamber 22. After the water flows into the culture chamber 22, the overall weight of the culture chamber 22 increases. At this time, the culture chamber 22 can move down in the culture box 1 and be suspended in the culture box 1 again under the action of the counterweight 21 and the salt water. At this time, the control pipe 33 slides in the opposite direction in the connecting pipe 32 under the action of the spring 35, so that the positions of the drainage channel 37 and the leakage channel 36 are misaligned, preventing the water from flowing down.

[0062] When the water in the cultivation chamber 22 evaporates, it can move upward under the action of the counterweight 21 and the salt water, and the water flows through the connecting pipe 32, control pipe 33, slow flow pipe 38 and pre-embedded pipe 23 and multiple seepage holes on the surface of the pre-embedded pipe 23 to directly irrigate the roots and stems of the seedlings, ensuring the normal water requirements for the growth of the seedlings, realizing quantitative water injection and irrigation, and avoiding water waste;

[0063] When the culture chamber 22 moves upward, allowing water to flow out through the connecting pipe 32 and control pipe 33, some water can be stored in the spray pipe 49 through the drainage telescopic pipe 48 and rotary joint 47. As the culture chamber 22 moves upward, the integrally formed sliding protrusion 44 inside the rotating sleeve 42 can slide within the spiral groove 43 on the surface of the fixed rod 41, causing the rotating sleeve 42 to rotate. This causes the rotating sleeve 42 to drive the rotary joint 47 to rotate, and the L-shaped connecting plate 411 connected to the outside of the rotary joint 47 to rotate. At this time, the piston 46 moves towards the side closer to the partition plate 414, causing... Air can enter the cavity inside the rotating sleeve 42, while water flows through the connecting pipe 32, control pipe 33, slow-flow pipe 38 and pre-embedded pipe 23 to directly irrigate the roots and stems of the seedlings. After the cultivation chamber 22 moves down, the rotating sleeve 42 can move down in the opposite direction to rotate the rod, and the air entering the cavity of the rotating sleeve 42 is compressed through the air pipe 415 to the position below the partition 414, and the gas pressurizes the water that has been pre-entered into the spray pipe 49, and sprays the water in the spray pipe 49 out through the nozzle on its surface. The spray pipe 49 can spray the outside of the seedlings in a ring shape, so as to ensure the all-round irrigation of the seedlings.

[0064] When the L-shaped connecting plate 411 on the outside of the rotary joint 47 rotates, the toothed loosening cone 412 installed on the bottom surface of the L-shaped connecting plate 411 can loosen the surface layer of the culture soil, so as to prevent the surface soil from hardening after the loss of surface moisture, thus ensuring the normal growth of seedlings.

[0065] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
