Description

Technical Field

[0001] This utility model relates to the field of drip irrigation device technology, specifically a drip irrigation device for agricultural planting. Background Technology

[0002] Drip irrigation is a highly efficient micro-irrigation system that delivers water and nutrients directly, slowly, and precisely to the soil around the roots of crops through a low-pressure pipeline system (usually plastic pipes). Its core principle is to apply water directly to the vicinity of plant roots in the form of drops, streams, or sprays, minimizing waste caused by evaporation, runoff, and deep seepage.

[0003] Drip arrows are a commonly used pipe-mounted irrigation device in drip irrigation systems. They are particularly suitable for applications requiring precise and independent control of water and fertilizer for each plant, such as potted plants, seedbeds, greenhouse row crops, or individual irrigation of orchard plants. By inserting the drip arrow into the soil, the water flow is delivered through an extended capillary tube to the dripper at the end of the drip arrow and then drips out. The water flow is applied directly to the surface or shallow layer of the root zone soil of the target plant in the form of stable droplets or fine streams.

[0004] The core advantage of drip irrigation is that it delivers water directly and slowly to the root zone of plants, minimizing evaporation and runoff losses and promoting downward root growth. Different crops have different root depths. For example, shallow-rooted plants (such as lawns, some vegetables, and seedlings) require shallow insertion depths, typically 5-10 cm; medium-rooted plants (such as most vegetables, flowers, and shrubs) typically require 10-15 cm; and deep-rooted plants (such as fruit trees, arborescent trees, and vines) require deeper insertion, possibly reaching 15-30 cm or even deeper. As the crop grows, the insertion depth of the drip arrow needs to be adjusted. Therefore, the insertion depth of the drip arrow is limited according to the root depth of different crops. However, the current method of controlling the insertion depth of drip arrows relies on the experience of the personnel, which makes it impossible to accurately control the insertion depth and easily leads to insertion that is too deep or too shallow due to insufficient experience. Based on this, a drip irrigation device for agricultural planting is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a drip irrigation device for agricultural planting in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drip irrigation device for agricultural planting, comprising a drip arrow body and a drip channel, wherein the drip channel is symmetrically formed on the outer side of the arrow shaft of the drip arrow body, and an arc-shaped groove is provided on the outer side of the vertical part of the arrow shaft of the drip arrow body, wherein the arc-shaped groove is perpendicular to the drip channel. The main body of the drip arrow is equipped with a depth positioning component through an arc-shaped slot. The depth positioning component is used to limit the depth at which the shaft of the drip arrow is inserted into the soil. The depth positioning component includes a positioning ring, an opening groove, a telescopic groove, a side-inverted concave seat, and a fan-shaped locking block; The positioning ring is sleeved on the outside of the vertical part of the arrow shaft of the main body of the arrow. The opening slots are symmetrically opened on both sides of the inner wall of the positioning ring. The telescopic slots are symmetrically opened at the upper and lower ends of the positioning ring and communicate with the opening slots. The side-inverted concave seat is slidably installed on the inside of the opening slot and the telescopic slot. The fan-shaped locking block is fixed on the side of the side-inverted concave seat near the main body of the arrow and is locked in the inside of the arc-shaped locking slot, which is used to realize the positioning ring and the arrow body of the arrow in a limited and fixed position. When the main body of the drip arrow is inserted into the soil, the insertion depth of the main body of the drip arrow is limited by the contact between the positioning ring and the ground.

[0007] As a further improvement of this utility model: multiple arc-shaped slots are evenly arranged in the vertical direction, and the height of the fan-shaped card block matches the height of the arc-shaped slot.

[0008] As a further improvement of this utility model: a W-shaped spring is also provided on the inner side of the side-inverted concave seat, and the two sides of the W-shaped spring are respectively in close contact with the inner wall side of the side-inverted concave seat and the inner wall side of the opening groove. An arc-shaped handle is fixed to the side of the side-inverted concave seat away from the fan-shaped block, and the arc-shaped handle is bent toward the center of the positioning ring.

[0009] As a further improvement of this utility model: the inner side of the positioning ring is also symmetrically fixed with limiting protrusions, the limiting protrusions and the opening groove are distributed at a 90-degree angle along the circumference, and the limiting protrusions are slidably connected to the vertical groove of the drip channel, and the protruding length of the limiting protrusions is less than the depth of the drip channel.

[0010] As a further embodiment of this utility model: the positioning ring, the opening groove, the telescopic groove, and the limiting protrusion are integrally formed by injection molding; the side-inverted concave seat, the fan-shaped card block, and the arc handle are integrally formed by injection molding; and the W-shaped spring is separately formed by injection molding.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting up a depth positioning component, the positioning ring acts as a physical limiter, which can fix the insertion depth by pressing against the soil surface, avoiding problems of inserting too deep or too shallow due to experience. The height of the positioning ring can be adjusted for shallow-rooted or deep-rooted crops, achieving standardized management. Moreover, when inserting the drip arrow into the soil, workers do not need to repeatedly measure the depth, effectively improving the efficiency of large-scale installation work.

[0014] 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.

[0015] Please see Figs. 1-4 In this embodiment of the present invention, an agricultural drip irrigation device includes a drip arrow 1 consisting of a drip arrow body 101 and a drip channel 102. The drip channel 102 is symmetrically formed on the outer side of the arrow shaft of the drip arrow body 101. An arc-shaped groove 103 is also provided on the outer side of the vertical part of the arrow shaft of the drip arrow body 101. The arc-shaped groove 103 is perpendicular to the drip channel 102. The main body 101 of the dripping arrow is equipped with a depth positioning component 2 through an arc-shaped slot 103. The depth positioning component 2 is used to limit the depth of the arrow shaft of the main body 101 inserted into the soil. The depth positioning component 2 includes a positioning ring disk 201, an opening groove 202, a telescopic groove 203, a side-tilting concave seat 204, and a fan-shaped locking block 205; The positioning ring 201 is sleeved on the outside of the vertical part of the arrow shaft of the arrow body 101. The opening groove 202 is symmetrically opened on both sides of the inner wall of the positioning ring 201. The telescopic groove 203 is symmetrically opened on the upper and lower ends of the positioning ring 201 and communicates with the opening groove 202. The side-inverted concave seat 204 is slidably installed on the inner side of the opening groove 202 and the telescopic groove 203. The fan-shaped locking block 205 is fixed on the side of the side-inverted concave seat 204 near the arrow body 101 and is locked in the inner side of the arc-shaped locking groove 103 to realize the positioning ring 201 and the arrow body 101 for limiting and fixing. When the arrow shaft of the dripping arrow body 101 is inserted into the soil, the insertion depth of the dripping arrow body 101 is limited by the positioning ring disk 201 contacting the ground. Multiple arc-shaped slots 103 are evenly arranged in the vertical direction, and the height of the fan-shaped card block 205 matches the height of the arc-shaped slot 103. The inner side of the side-inverted concave seat 204 is also provided with a W-shaped spring piece 207, and the two sides of the W-shaped spring piece 207 are respectively in close contact with the inner wall side of the side-inverted concave seat 204 and the inner wall side of the opening groove 202. An arc-shaped handle 206 is fixed to the side of the top of the side-inverted concave seat 204 away from the fan-shaped locking block 205. The arc-shaped handle 206 is bent toward the center of the positioning ring disk 201.

[0016] In this embodiment, it should be noted that the drip irrigation principle of this drip arrow 1 is the same as that of commonly available drip arrows on the market, and will not be elaborated on here. When inserting the drip arrow 1 into the soil, the height of the positioning ring 201 can be adjusted according to the required depth of the crop root system. Manually push the two arc-shaped handles 206 outwards to move the side-inverted concave seat 204 and the fan-shaped locking block 205 away from the drip arrow body 101. When the arc-shaped locking block 205 separates from the arc-shaped slot 103, the depth positioning component 2 can be moved up and down as a whole. When the height is determined, release the push on the arc-shaped handles 206. The arc-shaped handles 206, the side-inverted concave seat 204, and the fan-shaped locking block 205 will be reset under the elastic force of the W-shaped spring piece 207, so that the fan-shaped locking block 205 is locked into the arc-shaped slot 103 at this height position, thus fixing the depth positioning component 2. (It should be noted that the W-shaped spring piece 207 is always in a compressed state. The height difference between the bottom of the positioning ring 201 and the bottom of the drip arrow body 101 is the depth at which the drip arrow 1 is inserted into the soil.) Next, the bottom of the drip arrow body 101 is aligned with the soil and inserted. Finally, the positioning ring 201 contacts the ground. At this point, the drip arrow body 101 can no longer move down, thus achieving the height limit of the drip arrow 1. With the cooperation of the above-mentioned components, the positioning ring 201 acts as a physical limiter, which can fix the insertion depth by pressing against the soil surface, avoiding the problem of inserting too deep or too shallow due to experience. For shallow-rooted crops (such as lettuce) or deep-rooted crops (such as tomatoes), the height of the positioning ring 201 can be adjusted to achieve standardized management. Moreover, when inserting the drip arrow 1 into the soil, workers do not need to repeatedly measure the depth, which effectively improves the efficiency of large-scale installation work.

[0017] Please refer to this carefully. Figs. 1-3 The inner side of the positioning ring 201 is also symmetrically fixed with limiting protrusions 208. The limiting protrusions 208 and the opening groove 202 are distributed at ninety degrees along the circumference, and the limiting protrusions 208 are slidably connected to the vertical groove of the drip channel 102. The protruding length of the limiting protrusions 208 is less than the depth of the drip channel 102.

[0018] In this embodiment: the limiting protrusion 208 slides along the drip channel 102 to guide and limit the up and down movement of the positioning ring disk 201, thereby preventing the positioning ring disk 201 from rotating and ensuring the stable alignment of the fan-shaped card block 205 and the arc-shaped card groove 103.

[0019] Please refer to this carefully. Figs. 1-3 The positioning ring 201, the opening groove 202, the telescopic groove 203, and the limiting protrusion 208 are integrally formed by injection molding. The side-tilted concave seat 204, the fan-shaped locking block 205, and the arc handle 206 are integrally formed by injection molding. The W-shaped spring sheet 207 is separately formed by injection molding.

[0020] In this embodiment: the three parts of the depth positioning component 2 can be assembled after being injection molded independently, which facilitates standardized production, keeps costs under control, and makes it easy to promote and use. It should be noted that the main body of the drip arrow 101, the drip channel 102, and the arc-shaped groove 103 are integrally formed by injection molding, which is the same as the existing drip arrow production process, making it easy to improve production based on existing equipment.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
