Efficient water and fertilizer drip irrigation device for sandy soil apple trees

Abstract

This utility model discloses a high-efficiency water and fertilizer drip irrigation device for apple orchards in gravelly soil, relating to the field of drip irrigation technology. It includes a main water supply pipe placed horizontally on the ground, with flanges fixedly connected to both ends. The main water supply pipe is interconnected with a water supply device via the flanges, and the end of the main water supply pipe furthest from the water supply device is sealed. The main water supply pipe has corrugated pipes spaced at equal intervals, and the top of the main water supply pipe has equally spaced openings. This high-efficiency water and fertilizer drip irrigation device for apple orchards in gravelly soil achieves active adjustment of the water supply pipe length by equally spaced corrugated pipes on the main water supply pipe. This solves the limitations of traditional devices with fixed lengths that cannot adapt to different operational needs. The corrugated pipes adopt a pleated design, allowing construction personnel to axially stretch or compress their length. When it is necessary to extend the irrigation coverage area, the pleats of the corrugated pipe unfold to increase the overall pipeline length; conversely, compressing the pleats shortens the length, improving the flexibility of the irrigation layout.

Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, specifically a high-efficiency water and fertilizer drip irrigation device for apple orchards in gravelly soil. Background Technology

[0002] Apple fertilizer drip irrigation device is a drip irrigation and fertilization system specially designed for apple tree planting. It delivers water and fertilizer to the root zone of apple trees in a drip manner through pipes, achieving the purpose of water conservation and efficient fertilization.

[0003] For example, Chinese Patent Publication No. CN221011294U discloses a drip irrigation device for apple cultivation, relating to the field of drip irrigation device technology. It includes a fixed base, inside which two sets of opposing hydraulic telescopic rods are fixedly installed. A water-carrying ring is fixedly installed at the right end of each hydraulic telescopic rod. A rigid water-carrying pipe and a flexible water-carrying pipe are fixedly installed on the left and right sides of the water tank, respectively. The water-carrying ring is hollow and connected to the flexible water-carrying pipe. Through the arrangement of the hydraulic telescopic rods, water-carrying rings, and drip irrigation pipes, the trunk of the apple tree can be positioned between the two sets of water-carrying rings according to the size of the apple tree, ensuring that the roots are evenly irrigated, thereby improving the effect and efficiency of drip irrigation. Simultaneously, the water tank, scale lines, and flexible water-carrying pipes allow for control of the amount of water dripped onto the apple tree, ensuring that the apple tree receives the appropriate amount of water, improving the drip irrigation effect, and guaranteeing normal growth.

[0004] The length of the water supply pipe of the drip irrigation system is usually fixed and lacks a flexible adjustment mechanism. It is difficult to make appropriate adjustments according to different operational needs. During use, the drip irrigation pipe is easily squeezed or compressed by the outside, which can cause the pipe to deform and thus affect the uniform distribution of water flow and water supply efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a highly efficient drip irrigation device for apple orchards in gravelly soil, in order to solve the problem that the water supply pipe of the drip irrigation device in the above-mentioned background art is usually fixed in length, lacks a flexible adjustment mechanism, and is difficult to adjust appropriately according to different operational needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency water and fertilizer drip irrigation device for apples in gravelly soil, comprising a main water supply pipe placed horizontally on the ground, with flanges fixedly connected to both ends of the main water supply pipe, the main water supply pipe being interconnected with the water supply device through the flanges, and the end of the main water supply pipe away from the water supply device being sealed.

[0007] The main water supply pipe is provided with corrugated pipes that are evenly spaced apart. The top of the main water supply pipe is provided with openings that are evenly spaced apart. A diversion structure is installed inside the openings. A drip irrigation pipe is installed at the end of the diversion structure that is away from the main water supply pipe. The drip irrigation pipe is a composite structure consisting of a protective layer and a guide pipe.

[0008] Preferably, the outer side of the protective layer is light-colored, the guide tube is fixedly connected to the inner side of the protective layer, and the protective layer is provided with equally spaced support rings, which are sleeved on the outer side of the guide tube.

[0009] Preferably, the support ring is made of rigid PE material, the top of the protective layer has equidistant protrusions, the support ring is located inside the protrusions, and the protrusions form equidistant grooves on the outside of the protective layer.

[0010] Preferably, the diversion structure includes a connecting ring fixedly connected to the opening at the top of the main water supply pipe, the connecting ring having internal threads, and a filter tank being internally threaded into the connecting ring.

[0011] Preferably, the filter tank extends into the main water supply pipe, and a rotating block is fixedly connected to the top of the filter tank, with the rotating block and the main water supply pipe being vertically distributed.

[0012] Preferably, a hand-tightening handle is fixedly connected to the top of the rotating block, and a connecting pipe perpendicularly distributed to one side of the rotating block is fixedly connected to it, with a threaded sleeve threadedly connected to the outside of the connecting pipe.

[0013] Preferably, a quick-release structure is formed between the outer side of the connecting pipe and the inner side of the threaded sleeve, the end of the drip irrigation pipe is installed on the inner side of the connecting pipe and the threaded sleeve, and the rotating block is provided with a flow channel, the two ends of which are respectively connected to the inside of the filter tank and the inside of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This efficient drip irrigation device for apple orchards in gravelly soil utilizes corrugated pipes spaced evenly along the main water supply pipe to enable active adjustment of the pipe length. This overcomes the limitations of traditional devices with fixed lengths that cannot adapt to different operational needs. The corrugated pipes feature a pleated design, allowing construction workers to axially stretch or compress their length. When it is necessary to extend the irrigation coverage, the pleats of the corrugated pipes unfold to increase the overall pipeline length; conversely, compressing the pleats shortens the length, enhancing the flexibility of the irrigation layout.

[0016] Through the composite design and protective elements of the drip irrigation pipe, it effectively resists external compression, prevents pipe deformation from affecting the uniform distribution of water flow and water supply efficiency, and the protective layer wraps around the guide pipe to form a buffer layer, which absorbs the impact when external force is applied. At the same time, the rigid PE material support ring inside is tightly fitted to the outer wall of the guide pipe, forming a ring skeleton under pressure to maintain the shape of the inner cavity, ensuring that water can still seep out evenly from the drip irrigation pipe under soil and rock pressure, thus ensuring stable water supply performance in gravelly soil.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: a high-efficiency drip irrigation device for apple orchards in gravelly soil, comprising a main water supply pipe 1 placed horizontally on the ground, with flanges 2 fixedly connected to both ends of the main water supply pipe 1, and the main water supply pipe 1 connected to the water supply device through the flanges 2, the end of the main water supply pipe 1 away from the water supply device being sealed; the main water supply pipe 1 is provided with corrugated pipes 3 distributed at equal intervals, and the top of the main water supply pipe 1 is provided with equally distributed openings, inside which a diversion structure is installed, and a drip irrigation pipe 4 is installed at the end of the diversion structure away from the main water supply pipe 1, the drip irrigation pipe 4 being a composite structure composed of a protective layer 6 and a guide pipe 7; the outer side of the protective layer 6 is light-colored, the guide pipe 7 is fixedly connected to the inner side of the protective layer 6, and the inner side of the protective layer 6 is provided with equally distributed support rings 8, which are sleeved on the outer side of the guide pipe 7; the support rings 8 are made of rigid PE material, and the top of the protective layer 6 is provided with equally distributed protrusions 9, supporting... The support ring 8 is located inside the protrusion 9, and the protrusion 9 forms equidistant grooves on the outside of the protective layer 6; the diversion structure includes a connecting ring 5 fixedly connected to the opening at the top of the main water supply pipe 1, the connecting ring 5 has a thread inside, and a filter tank 10 is threaded inside the connecting ring 5; the filter tank 10 extends into the inside of the main water supply pipe 1, and a rotating block 11 is fixedly connected to the top of the filter tank 10, the rotating block 11 and the main water supply pipe 1 are perpendicularly distributed; a hand-tightening handle 12 is fixedly connected to the top of the rotating block 11, and a connecting pipe 13 perpendicularly distributed to one side of the rotating block 11 is fixedly connected to it, and a threaded sleeve 14 is threadedly connected to the outside of the connecting pipe 13; a quick-release structure is formed between the outside of the connecting pipe 13 and the inside of the threaded sleeve 14, the end of the drip irrigation pipe 4 is installed inside the connecting pipe 13 and the threaded sleeve 14, and a flow channel 15 is provided inside the rotating block 11, the two ends of the flow channel 15 are respectively connected to the inside of the filter tank 10 and the inside of the connecting pipe 13.

[0026] Both ends of the main water supply pipe 1 are fixedly connected by flanges 2. One end is connected to the water supply device to input irrigation water or fertilizer solution; the other end remains sealed, forming a closed pipeline system. The main water supply pipe 1 integrates corrugated pipes 3 that are evenly spaced. When the actual irrigation area needs to be expanded, the corrugated pipe 3 can be physically stretched to unfold and extend the effective coverage length of the main water supply pipe 1. Conversely, when the coverage length needs to be shortened to adapt to smaller plots or irregular terrain, the corrugated part of the corrugated pipe 3 can be compressed. This allows the length of the main water supply pipe 1 to be continuously and flexibly adjusted, which can fit apple planting areas with different areas and shapes of gravelly soil.

[0027] The upper end of the diversion structure is connected to the drip irrigation pipe 4 through an efficient quick-release connection. The drip irrigation pipe 4 is a double-layer composite structure, consisting of an outer protective layer 6 and an inner guide pipe 7 tightly combined. The outer surface of the protective layer 6 is light-colored and has good light reflection ability, which can effectively reduce the absorption of solar heat, thereby preventing the water and fertilizer inside the guide pipe 7 from deteriorating or breeding microorganisms due to excessive temperature.

[0028] The protective layer 6 has rigid PE material support rings 8 embedded at equal intervals inside. The support rings 8 are tightly fitted on the outside of the guide pipe 7. When the drip irrigation pipe 4 is subjected to external pressure or soil compression, the protective layer 6 first provides a buffer to disperse some of the stress. At the same time, due to its rigidity, the embedded support rings 8 quickly form a strong annular support skeleton, effectively maintaining the circular flow cross section of the guide pipe 7, preventing it from being flattened and blocked, enhancing the overall structural strength and compressive strength of the drip irrigation pipe 4 in gravelly soil environments, and protecting the internal guide pipe 7 from direct damage. Equally distributed protrusions 9 are set on the outer surface of the protective layer 6. These protrusions 9 naturally form longitudinal grooves on the surface of the protective layer 6. The drip irrigation holes are not prefabricated, but are formed by drilling at the bottom of these grooves after the laying is completed. The drilling position is set in the groove, effectively avoiding the support rings 8 below, preventing the risk of accidental damage to the support rings 8 during drilling operations, and ensuring the integrity of the guide pipe 7.

[0029] When water flows through the main water supply pipe 1 and into the diversion structure, it must first pass through the filter tank 10. This structure can effectively intercept solid particle impurities in the water or fertilizer solution, preventing these impurities from eventually clogging the drip irrigation holes of the drip irrigation pipe 4, thus ensuring the stability and uniformity of drip irrigation. The top of the rotating block 11 has a convenient hand-tightening handle 12. When the filter tank 10 becomes clogged due to use or needs regular cleaning and maintenance, the operator does not need to interrupt the water supply of the entire main water supply pipe 1. Simply hold the hand-tightening handle 12 and rotate the entire rotating block 11 to easily unscrew the filter tank 10 from the connecting ring 5 for cleaning or replacement. After cleaning, it can be screwed back in for reuse. For diversion ports that are not in use, a special plug that matches the thread of the connecting ring 5 can be used to seal and block them.

[0030] The rotating block 11 has a flow channel 15 inside. The two ends of the flow channel 15 are connected to the upper inner cavity of the filter tank 10 and the inner cavity of the connecting pipe 13, respectively. The filtered clean water flows through the flow channel 15 to the connecting pipe 13. When installing the drip irrigation pipe 4, first insert the end of the drip irrigation pipe 4 into the connecting pipe 13 to ensure that it is properly fitted. Tighten the outer threaded sleeve 14. During the rotation and pressing process, the threaded sleeve 14 will apply a radial tightening force to the connecting pipe 13 and the end of the drip irrigation pipe 4 and achieve a reliable seal to prevent leakage. When it is necessary to disassemble or replace the drip irrigation pipe 4, simply rotate the threaded sleeve 14 in the opposite direction and loosen it. The drip irrigation pipe 4 can then be quickly pulled out of the connecting pipe 13, achieving efficient and convenient installation and disassembly.
