Description

Technical Field

[0001] This utility model relates to the technical field of low-altitude industrial test chambers, specifically to a drip irrigation component for biological agents at the roots of cowpea plants. Background Technology

[0002] During the growth of cowpeas, the microbial environment of the roots is crucial for nutrient absorption and root health. Therefore, biological agents are used to improve the rhizosphere microecology. However, traditional application methods cannot guarantee that the agents will reach the roots accurately and evenly. Therefore, the existing technology mainly uses drip irrigation to improve the accuracy and uniformity of agent delivery.

[0003] Because the taproot of cowpeas penetrates deep into the soil (up to 30-50cm) and the lateral roots extend laterally by about 20-30cm, while traditional drippers are fixed to the ground surface, the inoculant tends to concentrate in the shallow soil layer and cannot reach the taproot area and dense lateral root area. This easily leads to insufficient absorption of the inoculant by the deep roots. In addition, the live bacteria in the biological inoculant are sensitive to light (especially ultraviolet light) and temperature (the suitable temperature is 20-30℃, and the inactivation rate is ≥30% when it is >40℃). Therefore, when the inoculant is dripped into the shallow soil layer, it is easy to cause the inoculant activity to decrease, thereby reducing the nutrient supply to the cowpea roots.

[0004] Therefore, there is an urgent need for drip irrigation components for the roots of cowpea plants containing biological microorganisms to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biological agent drip irrigation component for the roots of cowpea plants, including an infusion tube and multiple insertion tubes, and a drip irrigation component set in each insertion tube for deep soil drip irrigation of the roots of cowpea plants. The drip irrigation assembly includes a rotating tube rotatably connected to the insertion tube. The rotating tube has a first annular hole on its inner side wall of the insertion tube. A rotating ring is rotatably connected to the first annular hole. The first annular hole has multiple through holes that communicate with the interior of the rotating tube. Multiple drip irrigation tubes are arranged in a ring array on the side of the rotating ring away from the rotating tube. The insertion tube is equipped with an anti-clogging component for preventing each drip irrigation tube from clogging.

[0006] A hollow ball is rotatably connected to one end of the rotating tube near the infusion tube. A connecting tube is fixedly connected to the side of the hollow ball away from the rotating tube. The end of the connecting tube away from the hollow ball is connected to the infusion tube.

[0007] The anti-clogging component includes a second annular hole formed on the side wall of the insertion tube. Multiple anti-clogging rings are slidably connected to the second annular hole. The end of each drip tube away from the rotating tube is located between the second annular hole and the anti-clogging ring. The insertion tube is provided with a drive component for driving each anti-clogging ring.

[0008] Each of the anti-clogging rings has a retaining ring fixedly connected to its opposite ends, and each retaining ring has multiple liquid outlet holes on the side away from the hollow sphere.

[0009] The drive assembly includes two symmetrically arranged drive circular plates that are slidably connected inside the cannula. Multiple square plates are hinged to one side of the two drive circular plates, and the end of each square plate away from the drive circular plate is connected to an anti-clogging ring.

[0010] The rotating tube has two threaded bars with opposite directions of rotation on its sidewall, and the two driving circular plates are respectively threaded to the threaded bars.

[0011] The two drive circular plates have two straight surfaces on their sidewalls, and the inner hole of the insertion tube is configured to match the shape of the drive circular plates.

Detailed Implementation

[0018] 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.

[0019] Example 1

[0020] Please see Figures 1-5 The illustrated biological agent drip irrigation component for the roots of cowpea plants includes an infusion tube 101 and multiple insertion tubes 102, and also includes a drip irrigation component set in each insertion tube 102 for deep soil drip irrigation of the roots of cowpea plants. The drip irrigation assembly includes a rotating tube 201 rotatably connected to the insertion tube 102. The rotating tube 201 has a first annular hole 202 on the inner side wall of the insertion tube 102. The first annular hole 202 is rotatably connected to a rotating ring 203. The first annular hole 202 has a plurality of through holes 207 that communicate with the interior of the rotating tube 201. A plurality of drip irrigation tubes 204 are arranged in an annular array on the side of the rotating ring 203 away from the rotating tube 201. The insertion tube 102 is provided with an anti-clogging assembly for preventing each drip irrigation tube 204 from clogging. It should be noted that by setting up the drip irrigation component, the biological agent can be drip-irrigated to the roots of the cowpea plants, allowing it to penetrate deep into the soil near the roots. This enhances the absorption of the biological agent by the deep roots. At the same time, the delivery of the biological agent to the deep soil reduces the risk of activity degradation due to factors such as light and temperature, thereby improving the nutrient supply to the cowpea roots.

[0021] Please see Figure 3 and Figure 5 In the figure, a hollow ball 205 is rotatably connected to one end of the rotating tube 201 near the infusion tube 101. A connecting tube 206 is fixedly connected to the side of the hollow ball 205 away from the rotating tube 201. The end of the connecting tube 206 away from the hollow ball 205 is connected to the infusion tube 101. It should be noted that by setting the hollow ball 205 and connecting it through the connecting tube 206, a rotating connection is formed between the rotating tube 201 and the infusion tube 101, thus not affecting the rotation of the rotating tube 201.

[0022] Please see Figure 3 and Figure 4 The anti-clogging component shown in the figure includes a second annular hole 301 opened on the side wall of the insertion tube 102. Multiple anti-clogging rings 302 are slidably connected to the second annular hole 301. The end of each drip tube 204 away from the rotating tube 201 is located between the second annular hole 301 and the anti-clogging rings 302. The insertion tube 102 is provided with a drive component for driving each anti-clogging ring 302. It should be noted here that the anti-clogging component reduces the risk of soil clogging the drip irrigation pipe 204.

[0023] Please see Figure 3 and Figure 4 In the figure, each anti-blocking ring 302 has a retaining ring 303 fixedly connected to its opposite ends. Each retaining ring 303 has multiple liquid outlet holes 304 on one side away from the hollow ball 205. It should be noted that the baffle ring 303 prevents soil from clogging the drip irrigation pipe 204, while the outlet hole 304 facilitates the drip irrigation of the roots of cowpea plants with biological agents.

[0024] Please see Figure 3 and Figure 5 The driving assembly shown in the figure includes two symmetrically arranged driving circular plates 401 that are slidably connected inside the insertion tube 102. Multiple square plates 402 are hinged to the opposite side of the two driving circular plates 401. The end of each square plate 402 away from the driving circular plates 401 is connected to the anti-blocking ring 302. Two threaded bars 403 with opposite threads are opened on the side wall of the rotating tube 201. The two driving circular plates 401 are respectively threaded to the threaded bars 403. It should be noted here that the configuration of the drive components facilitates the movement of each anti-blocking ring 302 towards or away from each other.

[0025] Please see Figure 3 The two drive circular plates 401 in the figure have two straight surfaces 404 on their side walls, and the inner hole of the insertion tube 102 is matched with the drive circular plate 401. It should be noted that the two straight surfaces 404 on the sidewalls of the two drive circular plates 401 and the inner hole of the insertion tube 102 are configured to match the shape of the drive circular plates 401, which provides guidance and limiting for the movement of the drive circular plates 401.

[0026] Working principle: When drip irrigation of the roots of cowpea plants with biological agents, first lay the infusion tube 101 near the roots of the cowpea plants, and then insert the insertion tube 102 near the roots of the cowpea plants. During the insertion process, the insertion depth of the insertion tube 102 can be determined according to the actual growth of the cowpea plants. After inserting the cannula 102 near the root of the cowpea plant, rotate the rotating tube 201, causing the two threaded strips 403 on the side wall of the rotating tube 201 to rotate. During the rotation of the two threaded strips 403, the two threaded strips 403 are driven to move closer to each other by the threaded meshing transmission between the two threaded strips 403 and the drive circular plate 401 and the guiding action between the drive circular plate 401 and the inner hole of the cannula 102. During the process of the two drive circular plates 401 moving closer to each other, they will push each square plate 402 to rotate, and then push each anti-blocking ring 302 to move away from each other under the pushing force. During the process of each anti-blocking ring 302 moving away from each other, the retaining rings 303 at both ends of each anti-blocking ring 302 will move away from the cannula 102 at the same time. After moving each anti-blocking ring 302 a certain distance, the water pump in the outlet tank can be started, thereby delivering the biological agent to the infusion pipe 101 and from each connecting pipe 206 to the rotating pipe 201. After the biological agent is delivered to the rotating pipe 201, it will flow from each through hole 207 to the drip irrigation pipe 204, and then from each drip irrigation pipe 204 to the space between the baffle ring 303 and the second annular hole 301, and finally from each outlet hole 304 to the vicinity of the roots of the cowpea plant. This realizes the drip irrigation operation of biological agent to the roots of the cowpea plant, allowing the biological agent to penetrate into the deep soil layer near the roots of the cowpea plant, thereby improving the deep absorption of the biological agent by the roots of the cowpea plant. At the same time, the delivery of the biological agent to the deep soil layer can reduce the risk of the biological agent activity decay caused by light and temperature factors, thereby improving the nutrient supply effect to the roots of the cowpea.

[0027] Example 2

[0028] Please see Figure 4 This embodiment further illustrates Example 1. In the figure, each rotating tube 201 has multiple vertical cut surfaces 5 arranged in a ring array on one end sidewall near the hollow sphere 205. It should be noted here that the vertical cut surface 5 makes it easier to rotate the rotating tube 201 using a wrench-like tool.

[0029] Example 3

[0030] Please see Figure 2 This embodiment is a further explanation of other embodiments. In the figure, each insertion tube 102 is fixedly connected to a conical head 6 at one end near the root of the cowpea plant. It should be noted that the conical head 6 facilitates the insertion of the cannula 102 deep into the vicinity of the root of the cowpea plant.
