Description

Technical Field

[0001] This utility model relates to the field of drip irrigation device technology, specifically a drip irrigation device with adjustable water-fertilizer ratio. Background Technology

[0002] As one of the core technologies of water-saving agriculture, drip irrigation technology delivers water and fertilizer directly and slowly to the root zone of crops through a pipeline system. For example, the agricultural drip irrigation device proposed in patent application number "CN202322731507.1" includes a water storage tank, and the water in the water storage tank can be drip-irrigated to different locations on the land through different pipelines.

[0003] In a pest-infested area, after spraying insecticides and fungicides to control the pests and diseases, the plants lose a large number of leaves, but the root system may still be intact. At this time, it is necessary to quickly supplement the plant with high-nitrogen (to promote rapid growth of new leaves) and all-nutrient water-soluble fertilizer through root irrigation to help the plant grow new leaves as soon as possible and restore its photosynthetic capacity.

[0004] Existing drip irrigation systems can only pre-select and configure a fixed ratio of water and fertilizer, and then deliver it to each branch pipe for drip irrigation and fertilization (e.g., Figure 1 When applied to a recovery drip irrigation system for a specific insect-infested area, it cannot specifically increase the water-to-fertilizer ratio in a single branch pipe. Utility Model Content

[0005] The purpose of this invention is to provide a drip irrigation device with an adjustable water-fertilizer ratio to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions: A drip irrigation device with adjustable water-fertilizer ratio includes branch pipelines, each branch pipeline including a drip irrigation pipe and an input pipe. A connecting port is fixedly connected to the upper part of the drip irrigation pipe near the input pipe, and an adjustment port is fixedly connected to the top of the connecting port. The radius of the adjustment port is larger than the radius of the connecting port. The control tube has a vertical cavity inside, and at the bottom of the vertical cavity is a control cavity with an increasing radius from top to bottom. Inside the control cavity is a platform-shaped sealing plug that can move up and down. A tension spring is fixed to the top of the inner wall of the vertical cavity. The bottom of the tension spring is connected to a movable ring. The bottom of the movable ring is connected to the sealing plug through an inverted U-shaped connecting rod. The tension spring provides a pre-tightening force to make the sealing plug move up and fit against the inner wall of the control cavity.

[0007] Preferably, one end of the drip irrigation pipe is fixedly connected to the input pipe, and the maximum flow rate of the drip irrigation pipe is greater than the maximum flow rate of the input pipe.

[0008] Preferably, the vertical cavity is provided with a pressurizing mechanism, which includes a rotating fixed shaft, with both ends of the fixed shaft rotatably connected to the inner wall of the vertical cavity, and a pressure plate and a pressure plate fixed on the fixed shaft.

[0009] Preferably, one end of the pressure plate is rotatably connected to an abutment wheel, and one side of the abutment wheel is in contact with the inner wall of the vertical cavity.

[0010] Preferably, a water inlet is fixed on the control pipe, and the water inlet is connected to the vertical cavity.

[0011] Preferably, the drip irrigation device further includes a water and fertilizer addition mechanism, which includes a water and fertilizer addition pipe. The water and fertilizer addition pipe is detachably connected to the water inlet via an extension hopper, a connecting ring, and a connecting hose. A central ring is fixed inside the connecting ring by a fixing rod, and a push shaft is fixed on the central ring. When the connecting hose is connected to the water inlet, the push shaft extends into the vertical cavity and can push the pressure plate.

[0012] The beneficial effects of this utility model are: This invention connects a connecting port and a regulating port to the drip irrigation pipe, which serves as a branch pipe. During drip irrigation, an external water and fertilizer addition mechanism can be connected separately to the regulating port. This allows the water and fertilizer from the external mechanism to mix with the existing water and fertilizer in the branch pipe, thus adjusting the final water and fertilizer ratio of the individual branch pipe. This enables additional nitrogen fertilizer to be added to a specific area for root repair. Simultaneously, the sealing plug of the regulating port connected to the external water and fertilizer addition mechanism automatically opens to facilitate water and fertilizer input. When the regulating port and the water and fertilizer addition mechanism are separated, the sealing plug closes the regulating chamber, allowing the existing water and fertilizer in the branch pipe to continue drip irrigation normally.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] A drip irrigation device with an adjustable water-to-fertilizer ratio includes branch pipes connected to a main pipeline. The main pipeline is connected to an external water-fertilizer mixing device via a water pump. After the water and fertilizer are mixed, they are fed into multiple branch pipes through the main pipeline, such as... Figure 1 The example pipe in the picture is a branch pipe. The branch pipe has an opening that allows for drip irrigation of water and fertilizer into the soil. The branch pipeline includes a drip irrigation pipe 101, one end of which is fixedly connected to an input pipe 102. The input pipe 102 is connected to one end of the main pipeline, such that the maximum flow rate of water in the drip irrigation pipe 101 exceeds the maximum flow rate of water in the input pipe 102.

[0017] A connecting pipe port 2 is fixedly connected to the upper part of the drip irrigation pipe 101 near the input pipe 102. A regulating pipe port 3 is fixedly connected to the top of the connecting pipe port 2. The radius of the regulating pipe port 3 is larger than the radius of the connecting pipe port 2. The control port 3 has a vertical cavity 301 inside, and a control cavity 302 with an increasing radius is opened at the bottom of the vertical cavity 301. A sealing plug 303 is installed in the control cavity 302. The sealing plug 303 adopts a platform design. When it moves upward, it can fit tightly against the inner wall of the control cavity 302 to seal the control cavity 302. A tension spring 304 is fixedly connected to the top of the inner wall of the vertical cavity 301. A movable ring 305 is fixedly connected to the bottom of the tension spring 304. A connecting rod 306 with an inverted U-shaped design is fixedly connected to the bottom of the movable ring 305. The bottom of the connecting rod 306 is fixedly connected to the sealing plug 303. The tension spring 304 applies an upward pulling force to the movable ring 305 and the connecting rod 306, causing the sealing plug 303 to be pulled upward and tightly fitted against the inner wall of the regulating cavity 302.

[0018] A pressurizing mechanism is provided inside the vertical cavity 301. The pressurizing mechanism is used to apply downward pressure to the sealing plug 303. The pressurizing mechanism includes a fixed shaft 4. Both ends of the fixed shaft 4 are rotatably connected to the inner wall of the vertical cavity 301. A pressure plate 401 and a pressure plate 402 are fixedly connected to the fixed shaft 4. One end of the pressure plate 402 and above the sealing plug 303 is rotatably connected to an abutment wheel 403. One side of the abutment wheel 403 is in contact with the inner wall of the vertical cavity 301 to prevent the pressure plate 402 and the pressure plate 401 from continuing to rotate clockwise. A water inlet 5 is fixedly connected to the regulating pipe 3. One end of the water inlet 5 is connected to the vertical cavity 301, and an annular groove 501 is provided on the other end. A water and fertilizer adding mechanism is provided on the outside of the water inlet 5. The water and fertilizer adding mechanism includes a water and fertilizer adding pipe 601. The water and fertilizer adding pipe 601 is connected to an external water and fertilizer adding device, which can input water and fertilizer with different proportions or different compositions than those in the main pipeline into the water and fertilizer adding pipe 601. An expansion bucket 602 is fixedly connected to one end of the water and fertilizer adding pipe 601. The expansion bucket 602 can expand the radius inside the pipeline to ensure the flow capacity of water and fertilizer. A connecting ring 603 is fixedly connected to one end of the expansion bucket 602, and a connecting hose 604 is fixedly connected to one end of the connecting ring 603. When connecting the water and fertilizer adding mechanism and the water inlet 5, one end of the connecting hose 604 can be sleeved on the outside of the water inlet 5, and then the connecting hose 604 can be fixed to the surface of the water inlet 5 using the clamp in the prior art, so as to realize the connection between the water inlet 5 and the water and fertilizer adding mechanism. A fixing rod 605 is fixedly connected inside the connecting ring 603. A center ring 606 is fixedly connected to the fixing rod 605 and located at the center of the connecting ring 603. A push shaft 607 is fixedly connected to the center ring 606. One end of the push shaft 607 extends to the outside of the connecting hose 604. When the connecting hose 604 is fixed to the water inlet 5, the push shaft 607 can extend into the interior of the vertical cavity 301 through the water inlet 5.

[0019] The working principle of the drip irrigation device with adjustable water-to-fertilizer ratio provided by this utility model is as follows: When the main pipeline supplies water and fertilizer in a fixed ratio to the branch pipeline, the water and fertilizer ratio input through the main pipeline is the same. When it is necessary to adjust the water and fertilizer ratio in a certain branch pipeline (such as to add nitrogen fertilizer to the drip irrigation coverage area of ​​a certain branch pipeline for root repair), connect the external water and fertilizer adding mechanism to the water inlet 5. When the external water and fertilizer adding mechanism is connected to the water inlet 5, the push shaft 607 can extend into the vertical cavity 301 through the water inlet 5. Simultaneously, the push shaft 607 can pass through the connecting rod 306 and press against the pressure plate 401, causing the pressure plate 401 to rotate counterclockwise. The pressure plate 401 drives the pressure plate 402 to rotate counterclockwise via the fixed shaft 4. When the pressure plate 402 rotates, it presses down on the sealing plug 303 via the contact wheel 403 and moves relative to the sealing plug 303. (When the push shaft 607...) When 07 reaches its maximum stroke, the contact wheel 403 has not yet reached the top center position of the sealing plug 303, causing the sealing plug 303 to move downward. The sealing plug 303 no longer seals the control chamber 302, and the external water and fertilizer adding mechanism can input the prepared water and fertilizer into the vertical chamber 301, and then enter the drip irrigation pipe 101 through the control chamber 302 and the connecting pipe 2. It mixes with the original water and fertilizer from the main pipeline and the input pipeline 102 and drip irrigation is carried out together to adjust the water and fertilizer ratio dripped into the branch pipeline.

[0020] Conversely, after the drip irrigation is completed and the water inlet 5 and the external water and fertilizer addition mechanism are separated, the sealing plug 303 will be pulled upward by the movable ring 305 and the connecting rod 306 under the action of the tension spring 304, so that the sealing plug 303 will close the control chamber 302 again, without affecting the normal drip irrigation of the branch pipeline. At the same time, the upward movement of the sealing plug 303 will also push the abutment wheel 403, causing the pressure plate 402 to rotate clockwise. The pressure plate 402 drives the pressure plate 401 to rotate clockwise and reset through the fixed shaft 4.

[0021] Compared with related technologies, the drip irrigation device with adjustable water-to-fertilizer ratio provided by this utility model has the following beneficial effects: This invention connects a connecting port 2 and a regulating port 3 to the drip irrigation pipe 101, which serves as a branch pipe. This allows for the separate connection of an external water and fertilizer addition mechanism to the regulating port 3 during drip irrigation. The water and fertilizer in the external water and fertilizer addition mechanism mixes with the existing water and fertilizer in the branch pipe, thereby adjusting the final water and fertilizer ratio of the individual branch pipe. This enables the additional supplementation of nitrogen fertilizer to a specific area for root repair. Simultaneously, when the regulating port 3 is connected to the external water and fertilizer addition mechanism, the sealing plug 303 can automatically open to facilitate water and fertilizer input. When the regulating port 3 and the water and fertilizer addition mechanism are separated, the sealing plug 303 closes the regulating chamber 302, allowing the existing water and fertilizer in the branch pipe to continue drip irrigation normally.
