Description

Technical Field

[0001] This utility model relates to the technical field of crop irrigation devices, specifically to an irrigation device for corn-soybean strip intercropping. Background Technology

[0002] Corn-soybean strip intercropping is a planting pattern that can increase soybean production without reducing corn yield, thereby producing more grain on existing arable land. Based on this characteristic, this planting pattern is widely used in hilly areas where arable land is scarce and fragmented. However, the water requirements of corn and soybean plants are not synchronized (specifically, corn plants require more water from the jointing stage to the tasseling and flowering stage, while soybean plants' peak water requirement is from the beginning of flowering to the grain filling stage; their peak water requirements are not synchronized). Therefore, in the case of strip intercropping, extensive integrated irrigation is not conducive to the healthy growth of the crops; separate irrigation based on their respective water requirements is necessary.

[0003] Furthermore, in hilly areas, irrigation water for farmland usually comes from simple water storage pits dug on-site at the location of the plot. The water volume is limited, and irrigation is carried manually in buckets to the location of the plants to be irrigated, and then each plant is watered individually using a ladle. This process is labor-intensive and slow. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage.

[0032] Corn-soybean strip intercropping is a planting pattern that can increase soybean production by one season without reducing (or slightly reducing) corn yield, thereby producing more grain on existing arable land. Based on this characteristic, this planting pattern is widely used in hilly areas and other regions with limited and fragmented arable land. However, the water requirements of corn and soybean plants are not synchronized (specifically, corn plants require higher water levels from the jointing stage to the tasseling and flowering stage, while soybean plants' peak water requirement is from the beginning of flowering to the grain filling stage; these peak water requirements are not synchronized). Therefore, when the two crops are intercropped in strips, extensive integrated irrigation is not feasible; separate irrigation is required for each crop's growth stage.

[0033] Furthermore, in hilly areas, irrigation water for farmland usually comes from simple water storage pits dug on-site at the location of the plot. The water volume is limited, and irrigation is carried manually in buckets to the location of the plants to be irrigated, and then each plant is watered individually using a ladle. This process is labor-intensive and slow.

[0034] In response to this, the present invention provides an irrigation device for corn-soybean strip intercropping, which is particularly suitable for irrigation operations in hilly areas where corn-soybean strip intercropping is carried out. It can irrigate each plant individually, saving water and reducing manual labor intensity.

[0035] Example 1:

[0036] like Figure 1 , Figure 2 As shown, this embodiment provides an irrigation device for corn-soybean strip intercropping, including a rotating drum 1, a water pump 2, a connecting pipe 3, a water pipe 4, and a support 5.

[0037] The rotating drum 1 is rotatably mounted on the bracket 5; the water pump 2 is fixedly mounted on the bracket 5; the connecting pipe 3 is located inside the rotating drum 1 and the two are coaxially and fixedly connected.

[0038] One end of the water pipe 4 passes through the peripheral wall of the rotating drum 1 and is fixedly connected to one end of the connecting pipe 3. The section of the water pipe 4 located outside the rotating drum 1 is wound around the peripheral wall of the rotating drum 1. The other end of the connecting pipe 3 is rotatably connected to the outlet pipe 21 of the water pump 2.

[0039] Therefore, when watering a corn-soybean strip intercropping plot using this irrigation device, the support 5 can be placed at a simple water storage pit at the location of the plot, and then the inlet pipe 22 of the water pump 2 can be inserted into the water storage pit. The water pump 2 can then be used to draw irrigation water from the water storage pit. The operator only needs to pull the end of the water pipe 4 to the plant to be irrigated (during this process, the roller gradually rotates to release the wound water pipe 4) to carry out precise irrigation of each plant. Moreover, the manual labor intensity is low during this process.

[0040] It should be understood that the water pump 2 can be either fuel-powered or electrically powered, and this invention is not limited thereto. The water pipe 4 should have the ability to be wound, and fluid should still be able to flow normally in the water pipe 4 when wound.

[0041] Specifically, such as Figure 9 As shown, a first annular groove 211 is provided on the end face of the water outlet pipe 21, and the end of the connecting pipe 3 away from the water pipe 4 is inserted into the first annular groove 211.

[0042] A second annular groove 31 is provided on both the outer and inner peripheral walls of the section of the connecting pipe 3 inserted into the first annular groove 211, and a third annular groove 212 is provided at the corresponding position of the water outlet pipe 21. A sealing ring 32 is installed in each of the second annular grooves 31.

[0043] Therefore, even when the end of the connecting pipe 3 away from the water pipe 4 rotates relative to the outlet pipe 21 of the water pump 2, there will be no leakage at the connection point.

[0044] Preferably, a plurality of spikes 51 extend downward from the lower part of the bracket 5.

[0045] Therefore, when the irrigation device is placed near the water storage pit, the support 5 can be firmly embedded in the soil below. Thus, even when the water pipe 4 is dragged by a person, the irrigation device is not easy to shift or even fall over, ensuring the safe and continuous operation of the irrigation.

[0046] Preferably, a slag-proof mesh cover (not shown in the figures) is installed at the end of the water inlet pipe 22 of the water pump 2, and the slag-proof mesh cover covers the end of the water inlet pipe 22 of the water pump 2.

[0047] Therefore, when the water inlet pipe 22 of the water pump 2 is placed in the water storage pit to draw irrigation water, the installation of a slag-proof net can effectively prevent water plants, duckweed, etc. in the simple water storage pit from being sucked into the water pump 2, thereby causing blockage of the water pump 2 and pipelines.

[0048] Example 2:

[0049] like Figures 3 to 8 As shown, this embodiment is based on embodiment 1, except that in this embodiment, the irrigation device further includes an insertion tube 6;

[0050] One end of the insertion tube 6 is fixedly connected to the end of the section of the water pipe 4 located outside the rotating drum 1, and the other end of the insertion tube 6 is a pointed tip 61 with a gradually decreasing diameter;

[0051] The tip 61 includes a water outlet section 611 and a transition section 612. The transition section 612 is located between the water outlet section 611 and the insertion tube 6. A plurality of water outlet holes 62 are provided on the peripheral wall of the water outlet section 611.

[0052] Based on this, after manually guiding the water pipe 4 to the location of the plant to be irrigated, the tip 61 can be inserted below the ground for irrigation, allowing the irrigation water to directly reach the soil near the roots. Compared to surface irrigation and subsequent infiltration, this reduces the evaporation of irrigation water at the plant (especially in hot weather), thus reducing the amount of water required per plant. This irrigation device is particularly significant in hilly areas where irrigation is carried out using simple water storage pits. The tip 61 facilitates insertion into the soil and reduces damage to the plant's roots during insertion. The water outlet 62 helps to evenly distribute the irrigation water in the soil at the plant's location. Clearly, the insertion pipe 6 is a rigid pipe.

[0053] More preferably, a plug 63 is slidably installed inside the insertion tube 6. The diameter of the plug 63 is smaller than the inner diameter of the insertion tube 6 and larger than the diameter of the large end of the water outlet section 611. A pull rod 64 is fixedly connected to the side of the plug 63 away from the tip 61, and a groove 641 is provided on the pull rod 64.

[0054] A slide rod 65 is slidably inserted into the peripheral wall of the insertion tube 6, and the slide rod 65 can slide along the radial direction of the insertion tube 6;

[0055] A slider 66 matching the inclined groove 641 is fixedly installed on one end of the slide rod 65 located inside the insertion tube 6, and the slider 66 is slidably inserted into the inclined groove 641; a slot 651 is opened on one end of the slide rod 65 located outside the insertion tube 6;

[0056] A support rod 67 is fixedly installed on the outer wall of the insertion tube 6. The end of the support rod 67 is hinged to the middle of a rocker arm 68. One end of the rocker arm 68 is inserted into the slot 651.

[0057] During the relative sliding of the slide rod 65 and the insertion tube 6, the slider 66 enables the pull rod 64 to slide within the insertion tube 6 along the axial direction of the insertion tube 6.

[0058] Therefore, by operating the end of the lever 68 away from the slide rod 65 (making it away from or close to the insertion tube 6), the slide rod 65 can slide relative to the insertion tube 6. Consequently, the slider 66 can make the pull rod 64 slide along the axial direction of the insertion tube 6, so that the plug 63 blocks the transition section 612 or connects to the transition section 612. Thus, the water outlet section 611 can switch between water outlet and no water outlet states. In the process of manually transferring the insertion tube 6 from one plant to another for watering, the water outlet section 611 can be stopped from watering by operating the lever 68, thereby avoiding waste of water for watering.

[0059] Preferably, the outer surface of the plug 63 is covered with a flexible padding layer.

[0060] Therefore, when the pull rod 64 moves toward the tip 61 to the plug 63 blocking transition section 612, the flexible pad can improve the sealing effect of the plug 63.

[0061] Preferably, a pressure relief valve (not shown in the drawings) is also connected to the outlet pipe 21 of the water pump 2.

[0062] Therefore, by setting an appropriate preset pressure relief, once the pressure in the water pipe 4 exceeds the preset pressure relief after the plug 63 seals the transition section 612, the pressure relief valve automatically releases pressure, thereby ensuring the safety of the irrigation system's pipeline after the plug 63 seals the transition section 612. Obviously, to avoid wasting irrigation water, the pressure relief port of this valve is connected to the water storage pit.

[0063] Even better, such as Figure 5 , Figure 6As shown, during the process of inserting the slide bar 65 into the insertion tube 6, the slider 66 causes the pull rod 64 to slide away from the tip 61;

[0064] A compression spring 69 is fixedly connected to one end of the rocker arm 68 away from the slide bar 65, and the other end of the compression spring 69 is fixedly connected to the outer peripheral wall of the insertion tube 6.

[0065] Therefore, during the process of manipulating the end of the rocker arm 68 away from the slide bar 65 to bring it closer to the insertion tube 6 (such as... Figure 5 Pressing down on the left end of the rocker arm 68 allows the slide bar 65 to be pulled out in a direction away from the insertion tube 6 (e.g., Figure 5 (Sliding upwards), under the action of the slider 66 abutting against the inclined groove 641, the pull rod 64 slides towards the tip 61 in the insertion tube 6, causing the plug 63 to block the transition section 612. Furthermore, when manually transferring the insertion tube 6 from the just-watered plant to the next plant, simply hold the insertion tube 6 and the end of the lever 68 away from the slider 65 with one hand, so that the end of the lever 68 away from the slider 65 is close to the insertion tube 6, thus blocking the water outlet section 611. After transferring to the next plant, it also facilitates a continuous insertion into the soil (without changing the gripping state; after gripping, the lever 68 and the insertion tube 6 form a...) Figure 8 The structure shown gradually increases in width towards the tip 61, making it easier for the user to apply force and preventing the user's palm from slipping on the insertion tube 6. After the tip 61 is inserted into the soil, the lever 68 is released. Under the action of the compression spring 69, the end of the lever 68 away from the slide rod 65 moves away from the insertion tube 6, and the slide rod 65 is inserted into the insertion tube 6. The pull rod 64 pulls the plug 63 away from the water outlet section 611, and water flows out of the water outlet section 611 again for irrigation.

[0066] More preferably, a plurality of guide slides 642 are provided on the pull rod 64, the peripheral wall of the guide slides 642 abuts against the inner wall of the insertion tube 6, and the guide slides 642 are provided with flow holes 643 that allow fluid to pass through.

[0067] Therefore, the pull rod 64 can slide smoothly inside the insertion tube 6 without shaking, and the flow passage 643 ensures smooth flow inside the insertion tube 6.

[0068] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
