TECHNICAL FIELD

DETAILED DESCRIPTION
[0030] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the following further describes the present application in combination with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present application, and are not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0031] The specific embodiments of the present application are described below in combination with the drawings.
[0032] Embodiment 1
[0033] In this embodiment, an agricultural irrigation equipment is proposed, please refer to Figures 1-8 The agricultural irrigation equipment includes two half rings 1, and the two half rings 1 are combined to form a circular ring as shown in Figure 1 around a crop (single plant).
[0034] Regarding the half ring 1, as shown in Figure 1And Figure 2 As shown in the figure, the upper part of the half ring 1 is provided with a lower concave rod groove 2, and the lower part of the rod groove 2 is provided with a water channel 16. Further, the water channel 16 located at the half ring 1 forms a closed waterway after the two half rings 1 form a ring.
[0035] Please continue to refer to Figure 1 And Figure 2 The closed waterway is supplied with water by an external device. Specifically, the half ring 1 is provided with a water pipe 14, and the water pipe 14 is connected with a water pump (not shown in the figure).
[0036] The inner side of the half ring 1 has a plurality of through holes 19 communicating with the water channel 16, and the second spray head 13 is embedded in the through hole 19. In this way, the water pumped by the water pump is discharged outward through the water pipe 14, the closed waterway and the second spray head 13. Further, the two half rings 1 are centered on the crop (single plant), so that the water discharged by the second spray head 13 will quickly infiltrate the soil around the crop.
[0037] Of course, the core of the present embodiment is not limited to the technical problem of improving the uniformity of water, but also to further reduce the evaporation of water. Therefore, please refer to Figures 1-4 A plurality of curved rods are arranged in each rod groove 2.
[0038] In the present embodiment, one half ring 1 is provided with three curved rods, which are respectively a first rod 3, a second rod 4 and a third rod 5. Specifically, the third rod 5 is closest to the axis of the half ring 1, the second rod 4 is next, and the first rod 3 is farthest from the axis of the half ring 1.
[0039] Further, the end of the first rod 3, the second rod 4 and the third rod 5 is provided with a pin 6, which penetrates the groove wall (the groove wall on the inner side) of the rod groove 2, so that the first rod 3, the second rod 4 and the third rod 5 can rotate at the rod groove 2. It should be noted that, as shown in Figure 4 In order to cooperate with the curved part of the rod groove 2, the first rod 3, the second rod 4 and the third rod 5 are adjusted in length. Specifically, the length of the first rod 3 is less than that of the second rod 4, and the length of the second rod 4 is less than that of the third rod 5.
[0040] Further, the third rod 5 is specially provided with a sleeve 7. Of course, in order to adapt to the sleeve 7, a pin extension 8 is arranged at the pin 6 at the end of the third rod 5. In this way, the sleeve 7 is fixed at the third rod 5 by the pin extension 8.
[0041] The sleeve 7 has a cavity inside, so that the first spray head 9 shown in Figure 1 and Figure 2 is inserted into the through hole 19, and the water in the closed waterway is introduced into the sleeve 7 through the hose 15; for the water introduced into the sleeve 7, its role is to adjust the center of gravity of the third rod 5.
[0042] Specifically, as shown in Fig. 2, there is no water in the sleeve 7, so the weight of the first rod 3, the second rod 4, the third rod 5 and the membrane 20 makes the sleeve 7 rotate upward around the pin 6 at the third rod 5 as the axis; Figure 1
[0043] On the contrary, as shown in Fig. 3, there is a large amount of water in the sleeve 7, so the water and the weight of the sleeve 7 will pull the first rod 3, the second rod 4 and the third rod 5 to deflect toward the other half ring 1, forming a pattern as shown in Fig. 4. Figure 2 Figure 3 Figure 3
[0044] As mentioned above, another core purpose of the embodiment is to further reduce the amount of water evaporation, accordingly, the first rod 3, the second rod 4 and the third rod 5 after falling through the sleeve 7 and the water will form a pattern as shown in Fig. 5, which further illustrates that Figure 3 Figure 3 the membrane 20 is unfolded to form a shielding part above the half ring 1 for slowing down the evaporation of water vapor, reducing the range of soil exposure, and reducing the amount of water evaporation in the process of soaking into the soil.
[0045] Of course, the function of the sleeve 7 in the embodiment is not limited to changing the center of gravity, but also can be used as a blocking part to prevent the crops from being inclined, that is, part of the crops have a shallow root, so when the water soaks into the soil, the soil is slightly soft, which will make the part of the crops have a tendency to be inclined.
[0046] To this end, the sleeve 7 has a plurality of seepage holes 10 for draining water, wherein a plurality of seepage holes 10 slowly drain water outward after the sleeve 7 adjusts the center of gravity of the third rod 5 downward, which further illustrates that during the process of the water in the sleeve 7 draining outward through the plurality of seepage holes 10, the weight of the sleeve 7 and the water is not enough to resist the pulling force of the first rod 3 and the second rod 4 on the third rod 5, therefore, after the water in the sleeve 7 is drained, the first rod 3, the second rod 4 and the third rod 5 will finally be superimposed into the rod groove 2.
[0047] During the process of the first rod 3, the second rod 4 and the third rod 5 in the two half rings 1 being superimposed into the rod groove 2, the two sleeves 7 will rotate upward around the pin 6 at the third rod 5 as the axis, and during the upward rotation process, the two sleeves 7 form a blocking part to prevent the crops from being inclined to the root of the crops.
[0048] Embodiment 2
[0049] The embodiment is an improved example of embodiment 1, and the improvement includes enabling the sleeve 7 to move at the pin extension 8, thereby adjusting the sensitivity of the third rod 5 and adjusting the relative distance of the sleeve 7 to the crops.
[0050] For the convenience of review, the relevant contents in embodiment 1 are copied into this embodiment.
[0051] This embodiment presents an agricultural irrigation device; please refer to [link / reference]. Figures 1-8 The agricultural irrigation equipment consists of two semi-rings 1, which are combined around the crop (single plant) to form a single unit. Figure 1 The circular ring shown.
[0052] Regarding semi-ring 1, such as Figure 1 and Figure 2 As shown, a recessed rod groove 2 is provided above it, and a water channel 16 is provided below the rod groove 2. To further explain, the water channel 16 located at the semi-ring 1 forms a closed waterway after the two semi-rings 1 form a ring.
[0053] Please continue reading. Figure 1 and Figure 2 The closed waterway is supplied with water by external equipment. Specifically, water pipe 14 is installed at half ring 1, and water pipe 14 is connected to water pump (the water pump is not marked in the figure).
[0054] The inner side of the semi-ring 1 has several through holes 19 that communicate with the water channel 16. The second nozzle 13 is embedded in the through hole 19. In this way, the water pumped in by the water pump passes through the water pipe 14, the closed water channel and the second nozzle 13 and is discharged outward. To further explain, the two semi-rings 1 are centered on the crop (single plant). In this way, the water discharged by the second nozzle 13 will quickly soak the soil around the crop.
[0055] Of course, the core of this embodiment is not limited to the technical problem of improving the uniformity of water reception, but also aims to further reduce the amount of water evaporation. For details, please refer to [link / reference needed]. Figures 1-4 Multiple curved rods are set in each rod slot 2.
[0056] In this embodiment, a semi-ring 1 is equipped with three curved rods, namely the first rod 3, the second rod 4 and the third rod 5. Specifically, the third rod 5 is closest to the axis of the semi-ring 1, the second rod 4 is next, and the first rod 3 is farthest from the axis of the semi-ring 1.
[0057] To further explain, the ends of the first rod 3, the second rod 4, and the third rod 5 are all equipped with pins 6. These pins 6 penetrate the groove wall of the rod groove 2 (located on the inner side of the groove wall), allowing the first rod 3, the second rod 4, and the third rod 5 to rotate within the rod groove 2. It should be noted that, as... Figure 4 As shown, the lengths of the first rod 3, the second rod 4, and the third rod 5 have been adjusted to accommodate the curved part of the rod groove 2. Specifically, the length of the first rod 3 is less than that of the second rod 4, and the length of the second rod 4 is less than that of the third rod 5.
[0058] To further explain, the third rod 5 is also specially fitted with a sleeve 7. Of course, in order to fit the sleeve 7, a pin extension 8 is provided at the pin 6 at the end of the third rod 5. In this way, the pin extension 8 is inserted directly into the sleeve 7, so that the sleeve 7 is fixed at the third rod 5.
[0059] For sleeve 7, there is a cavity inside, thus, combined Figure 1 and Figure 2 The first nozzle 9 shown is inserted into the through hole 19, and water in the closed water channel is introduced into the sleeve 7 through the hose 15. The function of introducing water into the sleeve 7 is to adjust the center of gravity of the third rod 5.
[0060] Specifically, such as Figure 1 As shown in the figure, there is no water inside the sleeve 7. Thus, the weight of the first rod 3, the second rod 4, the third rod 5 and the membrane 20 causes the sleeve 7 to rotate upward about the pin 6 at the third rod 5 as the axis.
[0061] on the contrary, Figure 2 As shown, and refer to as Figure 3 In the diagram, there is a large amount of water inside the sleeve 7. Therefore, the weight of the water and the sleeve 7 will pull the first rod 3, the second rod 4, and the third rod 5 towards the other half-ring 1, forming a... Figure 3 The style shown.
[0062] As explained above, another core objective of this embodiment is to further reduce water evaporation. Accordingly, after passing through the sleeve 7 and the water dropper, the first rod 3, the second rod 4, and the third rod 5 will form as follows: Figure 3 The style shown further illustrates, Figure 3 The middle membrane 20 is unfolded to form a shield above the semi-ring 1 to slow down water vapor evaporation, reduce the exposed soil area, and reduce the amount of water evaporation during the process of water seeping into the soil.
[0063] Of course, in this embodiment, the function of the sleeve 7 is not limited to changing the center of gravity. It can also act as a blocking part to prevent the crop from tilting. That is, some crops have shallow roots, so when water soaks the soil and the soil becomes slightly loose, it will cause the crop to tilt.
[0064] In response, the sleeve 7 has several seepage holes 10 for draining water. After the sleeve 7 adjusts the center of gravity of the third rod 5 to move downward, the seepage holes 10 slowly drain water outward. To further explain, during the period when the water in the sleeve 7 is drained outward through the seepage holes 10, the weight of the sleeve 7 and the water is insufficient to resist the pulling force of the first rod 3 and the second rod 4 on the third rod 5. Therefore, after the water in the sleeve 7 is drained, the first rod 3, the second rod 4 and the third rod 5 will eventually overlap into the rod groove 2.
[0065] During the process of the first rod 3, the second rod 4 and the third rod 5 in the two semi-rings 1 being superimposed on the rod groove 2, the two sleeves 7 will rotate upward about the pin 6 at the third rod 5 as the axis. During the upward rotation, the two sleeves 7 form a blocking part at the root of the crop to prevent the crop from deviating.
[0066] Compared with Embodiment 1, this embodiment adds a collar 11, which can slide on the pin extension 8. To further explain, the collar 11 can engage at any position on the pin extension 8, thereby controlling the relative distance between the sleeve 7 and the pin 6 at the third rod 5.
[0067] It should be noted that the further the sleeve 7 is from the pin 6, the more the third rod 5 can pull the first rod 3 and the second rod 4 after injecting a small amount of water into the sleeve 7, so that the membrane 20 can unfold. Conversely, the closer the sleeve 7 is to the pin 6, the more water needs to be injected into the sleeve 7 so that the third rod 5 can pull the first rod 3 and the second rod 4.
[0068] To further explain, the farther the sleeve 7 is from the pin 6, the smaller the distance between the two sleeves 7 and the blocking parts formed on both sides of the crop rootstock. Conversely, the closer the sleeve 7 is to the pin 6, the larger the distance between the two sleeves 7 and the blocking parts formed on both sides of the crop rootstock. Thus, corresponding to the crop rootstock radius, crops with slightly larger rootstock radii require a larger distance and more water, while crops with slightly smaller rootstock radii can survive with a smaller distance and a small amount of water and prevent the crop from tilting.
[0069] Explanation regarding the formation of a ring from two semi-rings 1 in Examples 1 and 2:
[0070] Please see Figures 5-8 The semi-ring 1 is provided with a rod channel 17 located below the water channel 16. The rod channel 17 contains a first flexible rod 12 and a second flexible rod 18. The first flexible rod 12 is retracted into the rod channel 17, and the second flexible rod 18 extends outward from either end of the rod channel 17 (the second flexible rod 18 is fixed inside the rod channel 17). The outwardly extended part is inserted into the rod channel 17 of the other semi-ring 1, so that the two semi-rings 1 form a ring.
[0071] To facilitate fixing the assembled ring to the ground, the outwardly extending portion of the second flexible rod 18 is inserted into the rod channel 17 provided in the other half-ring 1, and pushes the first flexible rod 12 located in the other rod channel 17, causing the first flexible rod 12 to bend outward from the bottom of the half-ring 1 (a through groove 21 for bending the first flexible rod 12 outward is provided below the half-ring 1). To further explain, the portion of the first flexible rod 12 that bends outward from the bottom of the half-ring 1 can be embedded in the soil, serving as a fixing part for fixing the ring.
[0072] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
