Description

Technical Field

[0001] The present invention relates to the technical field of irrigation, and specifically relates to an irrigation device for cultivating forest seedlings. Background Art

[0002] Afforestation is a production activity of creating new forests or renewing existing ones. It is a basic link in forest cultivation. To ensure the diversity of forest species, different tree seedlings need to be planted in the same area. Different trees require different amounts of water during their growth processes. However, existing irrigation devices water the trees evenly, which is likely to waste water.

[0003] Chinese Patent CN216626933U discloses an irrigation device for cultivating forest seedlings, including: a water pipe; a connection mechanism installed on the side wall of the water pipe; a sealing mechanism fixed at the connection between the water pipe and the connection mechanism; a limiting mechanism installed at one end of the connection mechanism; an adjusting mechanism, where the adjusting mechanism includes a support rod, ridges, a rubber sleeve, a connecting strip, a slider, and a through hole. The inner side wall of the limiting mechanism is symmetrically provided with the through holes, and the side wall of the limiting mechanism is symmetrically installed with the rubber sleeves. The support rods are slidably connected inside the rubber sleeves and the through holes; the ridges and the sliders are installed on the side wall of the support rod, and the sliders are fixedly connected to the ridges; the side wall of the slider is installed with the connecting strip with an arc-shaped side wall, and the slider and the connecting strip are slidably connected inside the through hole.

[0004] Although the above solution can adjust the irrigation water volume according to different trees, when cultivating forest seedlings, different seedlings are uniformly planted in different areas. There will also be differences in the soil humidity of the seedlings located in the same area. For example, on the side that is often exposed to the sun, the water in the soil evaporates quickly, while on the other side, the water in the soil evaporates slowly. This can lead to differences in the water content in the soil of the same area. If all the seedlings are watered uniformly, the seedlings on the sunny side will lack water, while the seedlings on the shady side will have too much water. Summary of the Invention

[0005] In view of the above problems, a watering device for cultivating forest seedlings is provided. The base is placed on one side of the seedlings. The plug-in part is inserted into the soil on one side of the seedlings through the first adjustment device and the second adjustment device. Subsequently, a water pump arranged on one side of the water sprinkling pipe can pump water into the water sprinkling pipe. The water sprinkling pipe sprays the water flow onto the seedlings, and the water flow spreads in the soil around the seedlings. The soil around the plug-in part inserted into the soil gradually becomes moist, and the temperature also decreases accordingly. At this time, the expanded phase change material gradually shrinks, and the push plate slides downward along the axis of the sliding pipe. The ejector rod fixedly arranged on the upper part of the push plate no longer ejects the blocking component, and the blocking component blocks the water sprinkling pipe, so that the water sprinkling pipe does not keep watering, ensuring that the seedlings will not be drowned. After a period of time, the humidity of the soil around the seedlings continuously decreases. The humidity of the soil far away from the seedlings must be lower than that of the soil close to the seedlings. Thus, as time goes by, the humidity of the soil around the plug-in part will be greatly reduced, and the temperature of the plug-in part begins to rise. The phase change material arranged in the plug-in part expands when heated. The expanded phase change material pushes up the push plate and the ejector rod arranged on the push plate. The ejector rod pushes open the blocking component. In this way, the water sprinkling pipe can spray the water flow around the seedlings again. As the water flow is continuously sprayed, the soil around the plug-in part will also be wetted, thereby reducing the temperature of the plug-in part. The ejector rod descends, and the blocking component blocks the water sprinkling pipe. This cycle repeats, enabling the device to automatically supply water to the seedlings according to the actual situation without using electronic components, reducing the usage cost.

Detailed implementation manners

[0032] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0033] Refer to Figure 1 、 Figure 3 and Figure 6: A watering device for cultivating forest seedlings, comprising a base 1 and a watering device 2; the watering device 2 includes a water sprinkling pipe 21, a sliding pipe 211, a plugging assembly 22, a jacking rod 23, a pushing plate 231, a plug-in member 24, a first adjusting device 25 and a second adjusting device 26; the water sprinkling pipe 21 is horizontally arranged above the base 1, one end of the water sprinkling pipe 21 is provided with a water sprinkling opening, and the water sprinkling pipe 21 sprays water through the water sprinkling opening. A water pump is arranged on the side of the water sprinkling pipe 21 away from the water sprinkling opening, and the water pump pumps water into the water sprinkling pipe 21; the sliding pipe 211 is vertically arranged at the lower part of the water sprinkling pipe 21, and the sliding pipe 211 is communicated with the water sprinkling pipe 21; the plug-in member 24 is fixedly arranged at the bottom of the sliding pipe 211 along the axis of the sliding pipe 211, a cavity is arranged inside the plug-in member 24, an opening is arranged at the upper part of the plug-in member 24, and the sliding pipe 211 is communicated with the cavity inside the plug-in member 24; the pushing plate 231 is slidably arranged in the sliding pipe 211 along the axis direction of the sliding pipe 211, a gap exists between the pushing plate 231 and the bottom of the cavity in the plug-in member 24, and a phase change material is arranged in the gap; the jacking rod 23 is fixedly arranged at the upper part of the pushing plate 231 along the axis of the sliding pipe 211, a sealing plate is arranged at the communicating part of the sliding pipe 211 and the water sprinkling pipe 21, the jacking rod 23 penetrates through the sealing plate and is slidably matched with the sealing plate, and when the phase change material does not expand, the upper end face of the jacking rod 23 is coplanar with the upper end face of the sealing plate; the plugging assembly 22 is arranged on the water sprinkling pipe 21 above the jacking rod 23, the plugging assembly 22 can plug the water sprinkling pipe 21, and when the jacking rod 23 jacks out, it can jack up the plugging assembly 22; the first adjusting device 25 is arranged on one side of the base 1, and the first adjusting device 25 is used for adjusting the height of the water sprinkling pipe 21; the second adjusting device 26 is arranged on one side of the first adjusting device 25, and both ends of the second adjusting device 26 are respectively connected with the base 1 and the sliding pipe 211, and the second adjusting device 26 is used for adjusting the distance between the sliding pipe 211 and the base 1.

[0034] Since the upper end face of the ejector rod 23 is coplanar with the upper end face of the sealing plate when the phase change material is not expanded, the water flow in the water sprinkler pipe 21 will not flow into the sliding pipe 211. Place the base 1 on one side of the seedling, and insert the plug-in part 24 into the soil on one side of the seedling through the first adjusting device 25 and the second adjusting device 26. It should be noted that the phase change material is in an expanded state when not inserted into the soil, and at this time the blocking device blocks the water sprinkler pipe 21. Subsequently, the water pump arranged on one side of the water sprinkler pipe 21 can pump water into the water sprinkler pipe 21, and the water sprinkler pipe 21 sprays the water flow onto the seedling, and the water flow spreads in the soil around the seedling. The soil around the plug-in part 24 inserted into the soil gradually becomes wet, and the temperature also decreases accordingly. At this time, the expanded phase change material gradually shrinks, and the push plate 231 slides downward along the axis of the sliding pipe 211. The ejector rod 23 fixedly arranged on the upper part of the push plate 231 no longer ejects the blocking assembly 22, and the blocking assembly 22 blocks the water sprinkler pipe 21, so that the water sprinkler pipe 21 does not keep sprinkling water, ensuring that the seedling will not be drowned. After a period of time, the humidity of the soil around the seedling continuously decreases, and the humidity of the soil far from the seedling must be lower than that of the soil close to the seedling. Thus, as time goes by, the humidity of the soil around the plug-in part 24 will be greatly reduced, and the temperature of the plug-in part 24 begins to rise. The phase change material arranged in the plug-in part 24 expands when heated, and the expanded phase change material pushes up the push plate 231 and the ejector rod 23 arranged on the push plate 231. The ejector rod 23 pushes open the blocking assembly 22. In this way, the water sprinkler pipe 21 can spray the water flow around the seedling again. As the water flow is continuously sprayed, the soil around the plug-in part 24 will also be wetted, thereby reducing the temperature of the plug-in part 24, lowering the ejector rod 23, and the blocking assembly 22 blocks the water sprinkler pipe 21. This cycle repeats, enabling the device to automatically supply water to the seedling according to the actual situation without using electronic components, reducing the use cost.

[0035] Refer to Figure 1 and Figure 5 : The blocking assembly 22 includes a blocking plate 221, a first spring 222 and a mounting shell 223; the mounting shell 223 is vertically arranged on the upper part of the water sprinkler pipe 21; the blocking plate 221 is slidably arranged in the mounting shell 223 along the height direction of the mounting shell 223, the blocking plate 221 extends out from the bottom of the mounting shell 223, the blocking plate 221 penetrates through the upper part of the water sprinkler pipe 21 and is slidably matched with the water sprinkler pipe 21, the blocking plate 221 can completely block the water sprinkler pipe 21, and there is a first gap between the blocking plate 221 and the upper part of the mounting shell 223; the first spring 222 is arranged in the first gap.

[0036] When the plugging plate 221 is not lifted by the ejector rod 23, the plugging plate 221 completely plugs the water sprinkling pipe 21. When the phase change material at the lower part of the pushing plate 231 expands, the phase change material drives the pushing plate 231 to slide upward along the axis of the sliding pipe 211, and then the ejector rod 23 can lift the plugging plate 221. Subsequently, the water pump can pump water through the water sprinkling pipe 21. The first spring 222 arranged on the upper part of the plugging plate 221 can press the plugging plate 221 when the ejector rod 23 descends, so that the pressing plate can plug the water sprinkling pipe 21 again.

[0037] Refer to Figure 9 and Figure 10 : The water sprinkling device 2 further includes a positioning assembly. There are two positioning assemblies, and the two positioning assemblies are arranged on the sliding pipe 211 along the axis of the sliding pipe 211. The positioning assembly includes a sliding groove 212, a clamping block 213, a second spring 214 and a clamping groove; the sliding groove 212 is opened on the inner wall of the sliding pipe 211 along the radial direction of the sliding pipe 211; the clamping block 213 is slidably arranged in the sliding groove 212 along the length direction of the sliding groove 212. There is a second gap between the clamping block 213 and the bottom of the sliding groove 212, and chamfers are provided on the upper and lower sides of the clamping block 213; the second spring 214 is arranged in the second gap; the clamping groove is opened on the side wall of the pushing plate 231, and the clamping block 213 is in clamping fit with the clamping groove.

[0038] When the water pump sprays water to the seedlings through the water sprinkling pipe 21, there are certain requirements for the water pressure. If the positioning component is not set, the water flow will always be in the pumping state. This is because when the phase change material is not fully expanded, it cannot push up the blocking component 22 through the ejector rod 23. In this way, the water flow pumped out by the water pump will be blocked by the protruding blocking component 22 when passing through the water sprinkling pipe 21, thereby reducing the flow rate of the water flow. After the water is sprayed out, it will fall around the plug-in component 24, causing the plug-in component 24 to cool down, and the saplings can never be fully watered. After the positioning component is set, as the moisture in the soil around the plug-in component 24 continuously evaporates, the temperature of the phase change material in the plug-in component 24 will also continuously increase, thereby causing the phase change material to expand. However, since the clamping block 213 clamps the clamping groove on the side wall of the push plate 231, the push plate 231 will not slide. When the phase change material continues to expand, the thrust generated by the expansion will overcome the component force formed by the second spring 214 through the chamfer of the clamping block 213, causing the clamping block 213 to disengage from the clamping with the clamping groove, and the push plate 231 quickly pushes the ejector rod 23 upward, causing the blocking component 22 to be pushed open, and the water sprinkling pipe 21 is in a completely unobstructed state. The sprayed water can accurately fall below the seedlings. Since there are two positioning components, the positioning component located in the upper part performs secondary positioning on the push plate 231 at this time, that is, the soil humidity around the plug-in component 24 increases at this time, causing the plug-in component 24 to cool down, and the contracted phase change material will not immediately drive the push plate 231 to descend. Only after the push plate 231 overcomes the pressure of the second spring 214 in the upper positioning component will it retract, so as to ensure that the blocking component 22 can completely block the water sprinkling pipe 21.

[0039] Refer to Figure 3 and Figure 6 : The water sprinkling device 2 further includes a first heat conducting rod 232, a second heat conducting rod 233 and a heat absorbing plate 234; the first heat conducting rod 232 is fixedly arranged on the upper part of the push plate 231 on one side of the ejector rod 23 along the axis of the sliding tube 211; the second heat conducting rod 233 is fixedly arranged on the lower part of the push plate 231 along the axis of the sliding tube 211, and the end of the second heat conducting rod 233 away from the push plate 231 can contact the plug-in component 24; the heat absorbing plate 234 is arranged on the outer wall of the sliding tube 211 on one side of the first heat conducting rod 232.

[0040] When the external temperature rises and the moisture in the soil continuously evaporates, the heat absorption plate 234 will continuously absorb heat. The heat of the heat absorption plate 234 will be transferred to the first heat conduction rod 232, and then through the push plate 231 and the second heat conduction rod 233, it will be transferred to the plug-in part 24. In this way, the phase change material at the lower part of the push plate 231 will accelerate expansion. The expanded phase change material will push the push plate 231, and the push plate 231 will rise along the axis of the sliding tube 211. The second heat conduction rod 233 will be separated from the plug-in part 24, and the heat of the second heat conduction rod 233 cannot be transferred to the plug-in part 24. In this way, when the soil around the plug-in part 24 is soaked with water, the cooling speed of the plug-in part 24 will be faster, so that the plug-in part 24 can respond to the dry and wet conditions of the seedlings faster.

[0041] Refer to Figure 1 and Figure 3 : The first adjusting device 25 includes a driving device 251, a threaded rod 252 and a limiting component 253; a through groove is vertically penetrated through the base 1, and the threaded rod 252 is slidably arranged in the through groove along the axis of the through groove; the driving device 251 is arranged on the base 1, and the threaded rod 252 penetrates through the driving device 251 and is in threaded cooperation with the driving device 251; the limiting component 253 is respectively arranged on the threaded rod 252 and the side wall of the through groove, and the limiting component 253 is used to limit the rotation of the threaded rod 252.

[0042] The first adjusting device 25 can adjust the height of the sprinkler pipe 21. After the sprinkler pipe 21 is raised, the plug-in part 24 will also be pulled out of the soil. When the plug-in part 24 is adjusted to a suitable position through the second adjusting device 26, through the threaded cooperation between the driving device 251 and the threaded rod 252, and then the threaded rod 252 is restricted by the limiting component 253, so that the threaded rod 252 can only move along the height direction of the base 1, so that the plug-in part 24 is inserted into the soil again.
