Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation, in particular to a greenhouse buried irrigation structure. Background Art

[0002] In the modern agricultural production system, greenhouse cultivation, as a core component of facility agriculture, is playing an irreplaceable role. By constructing a closed or semi-closed controllable environment, greenhouse cultivation effectively isolates external adverse factors such as extreme climate, pests and diseases, and creates suitable temperature, humidity and light conditions for crop growth. Whether it is the stable supply of off-season vegetables in the north in winter or the cross-regional cultivation of tropical fruits in the south, greenhouse technology has broken the dependence of traditional agriculture on the natural environment.

[0003] Existing greenhouse underground irrigation pipes are buried in the crop root layer, and water is delivered to the roots in the form of dripping or micro-spraying through the water outlet holes in the pipe wall. This can reduce water evaporation and loss, stabilize water supply, avoid soil compaction and nutrient loss, promote root growth, and improve nutrient absorption efficiency.

[0004] However, the existing buried water pipes are only suitable for shallow root drip irrigation when crops are just planted because of the fixed irrigation height. As the crops grow, the roots continue to extend downward and the distribution range expands. Fixed-height irrigation makes it difficult to transport water to the active root areas, resulting in water shortage in the deep roots and excessive soaking of the surface roots. This not only reduces irrigation efficiency, but also easily leads to problems such as poor crop growth and the breeding of pests and diseases. Utility Model Content

[0005] The utility model can adjust the height of water irrigation by adjusting the function of the irrigation component, so as to avoid the situation where it is difficult to transport water to the active root area due to irrigation at a fixed height, resulting in water shortage in the deep roots and excessive soaking of the surface roots. This not only improves the irrigation efficiency, but also reduces the risk of pests and diseases breeding, ensures the production of crops, and solves the problems raised by the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a greenhouse underground irrigation structure, including a semicircular guard plate;

[0007] an adjusting irrigation assembly, arranged on the top of the semicircular guard plate;

[0010] Preferably, the outside of the two groups of the first dampers are both provided with a second spring, the outer surfaces of the two groups of the fixing plates are fixedly connected to the limiting columns, and the outer surfaces of the two groups of the limiting columns are slidably connected to the inner surface wall of the triangular block.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: Reference Figure 1 - Figure 5 Shown: A greenhouse underground irrigation structure, including a semicircular guard plate 1;

[0028] The irrigation adjustment component 2 is arranged on the top of the semicircular guard plate 1;

[0029] The regulating irrigation assembly 2 includes a connecting pipe 201, a water pipe 211 and two sets of fixed plates 212. A plane bearing 202 is fixedly installed on the top of the connecting pipe 201. A fixed guard plate 203 is fixedly installed on the outer surface of the connecting pipe 201 near the upper position. A sliding groove 204 is provided on the inner wall of the fixed guard plate 203. A delivery pipe 206 is fixedly installed on the top of the plane bearing 202. Two sets of sliding blocks 205 are fixedly installed on the outer surface of the delivery pipe 206 near the lower position. The outer surfaces of the two sets of sliding blocks 205 are slidably connected to the inner wall of the sliding groove 204. A limiting ring 207 is fixedly installed on the inner wall of the delivery pipe 206 near the upper position. The inner wall of the limiting ring 207 is slidably connected to a steering pipe 208. The outer surface of the steering pipe 208 is symmetrically fixed with limiting plates 209 near the lower position. The outer surfaces of the two sets of limiting plates 209 are provided with a first spring 210. The outer surfaces of the two sets of fixed plates 212 are both slidably connected with triangular blocks 213. 3 slides through the outer surface of the water pipe 211 and extends to one side. The outer surface of the triangular block 213 is fixedly installed with a first damper 214. The outside of the two groups of first dampers 214 is provided with a second spring 215. The outer surfaces of the two groups of fixed plates 212 are fixedly connected to the limiting columns 216. The outer surfaces of the two groups of limiting columns 216 are slidably connected to the inner surface wall of the triangular block 213. The outer surface of the fixed plate 212 is fixedly installed with an induction sensor 217. The top of the water pipe 211 is fixedly installed with a mounting plate 218. The top of the mounting plate 218 is fixedly installed with a servo motor 219. The output end of the servo motor 219 slides through the mounting plate 218 and the top of the water pipe 211 and extends to the bottom. The output end of the servo motor 219 is fixedly connected to the valve disc 220. The bottom of the connecting pipe 201 is fixedly connected to the top of the water pipe 211. The outer surfaces of the two groups of fixed plates 212 are fixedly installed with the outer surface of the water pipe 211, and the bottom of the water pipe 211 is fixedly installed with the top of the semicircular guard plate 1.

[0030] In this embodiment, in the greenhouse buried irrigation structure, the semicircular guard plate 1 serves as a basic support component, providing an installation foundation for the upper regulating irrigation assembly 2, ensuring that the entire irrigation structure is stably buried in the greenhouse soil. First, the water pipe 211 serves as the main water delivery channel. When the irrigation water flows through the water pipe 211, the water flow pressure acts on the triangular block 213, causing it to overcome the elastic force of the second spring 215 and the resistance of the first damper 214, and slide along the limit column 216. When the first damper 214 touches the fixing plate 212, the induction sensor 217 can monitor the triangular block 213. The sliding displacement can obtain the current water flow pressure information. When the water flow needs to be adjusted, the servo motor 219 above the mounting plate 218 is started to rotate, thereby driving the valve flap 220 to rotate, changing the opening and closing angle of the valve flap 220 and the inner wall of the water pipe 211 to adjust the water flow rate. The servo motor 219 drives the valve flap 220 to rotate, increasing the opening area, and vice versa to reduce the opening area to meet the water requirements of different crops at different growth stages. Then, a strong water flow will enter the connecting pipe 201, and the connecting pipe 201 serves as the entrance for the water flow to enter the regulating irrigation component 2. When the strong water flow passes through the connecting pipe 201, the connecting pipe 201 will be opened. When the connecting pipe 201 reaches the steering pipe 208, the plane bearing 202 can make the delivery pipe 206 rotate flexibly. The sliding groove 204 in the fixed guard plate 203 cooperates with the sliding block 205 to limit the radial movement of the delivery pipe 206 without affecting its axial rotation, providing a basis for the subsequent adjustment of the irrigation direction. When the water flow is too large, it will drive the steering pipe 208 to rise from the limiting ring 207, and the limiting plate 209 and the first spring 210 on the steering pipe 208 work together to limit the steering pipe 208. When the irrigation is finished, the first spring 21 0 is reset, driving the steering tube 208 to enter the interior of the delivery pipe 206. When the water flow is small, the water flow cannot drive the limit plate 209, so that the steering tube 208 cannot be raised, thereby realizing flexible adjustment of the irrigation direction, ensuring that the irrigation water flow can cover crops in different areas. Under the action of the adjustable irrigation component 2, the height of the water flow irrigation can be adjusted, avoiding the situation where it is difficult to transport water to the active root area due to irrigation at a fixed height, resulting in water shortage in the deep roots and excessive soaking of the surface roots. This not only improves the irrigation efficiency, but also reduces the risk of pests and diseases breeding, ensuring the production of crops.

[0031] Example 2: According to Figure 1 - Figure 6 As shown: the bottom of the semicircular guard plate 1 is fixedly connected to the connecting plate 3, and multiple groups of second dampers 31 are arranged and fixedly installed on the bottom of the connecting plate 3. Third springs 32 are provided on the outside of the multiple groups of second dampers 31, and positioning plates 33 are fixedly installed on the bottom of the multiple groups of second dampers 31.

[0032] In this embodiment, when underground irrigation operations are carried out, a strong water flow will continue to pass through the water pipe 211. First, the connecting plate 3 will first sense the pressure from the water flow. After being subjected to force, it will push the second damper 31 to compress the third spring 32. The second damper 31 uses its own damping characteristics to reduce the impact of external force on the irrigation structure. The third spring 32 absorbs part of the energy and provides a certain reverse elastic force, so that the entire irrigation structure produces a moderate buffering displacement when subjected to force. The positioning plate 33 can be embedded in the soil, further improving the stability and applicability of the irrigation structure.

[0033] Working principle: First, embed the positioning plate 33 into the soil. When the irrigation operation starts, the water will continue to flow through the water pipe 211. The connecting plate 3 will first sense the pressure from the water flow. After being subjected to the force, it will push the second damper 31 to compress the third spring 32. The second damper 31 uses its own damping characteristics to slow down the impact of the external force on the water pipe 211. When the irrigation water flows through the water pipe 211, the water pressure acts on the triangular block 213, causing it to overcome the elastic force of the second spring 215 and the resistance of the first damper 214, and slide along the limit column 216. When the first damper 214 touches the fixed plate 212, the induction sensor 217 can monitor the sliding displacement of the triangular block 213. When the water flow needs to be adjusted, the servo motor 219 is started to drive the valve disc 220 to rotate. The valve flap 220 and the inner wall of the water pipe 211 are moved to change the opening and closing angle of the valve flap 220 and the inner wall of the water pipe 211, thereby adjusting the water flow rate. Then, a strong water flow will enter the connecting pipe 201 and reach the steering pipe 208. Under the action of the plane bearing 202, the delivery pipe 206 can be flexibly rotated. The sliding groove 204 in the fixed guard plate 203 cooperates with the sliding block 205 to limit the radial movement of the delivery pipe 206 without affecting its axial rotation. When the water flow is too large, the steering pipe 208 will be driven to rise from the limiting ring 207, and the limiting plate 209 and the first spring 210 on the steering pipe 208 will work together to limit the steering pipe 208. When the irrigation is completed, the first spring 210 is reset, driving the steering pipe 208 to enter the interior of the delivery pipe 206.

[0034] By following the above-mentioned procedures, the underground irrigation structure of the greenhouse can be used.
