Description

Technical Field

[0001] The invention relates to the technical field of agricultural irrigation, and in particular to irrigation equipment for precise management of water and fertilizer in dryland farmland. Background Art

[0002] In agricultural production, irrigation and fertilization management of dryland farmland has always been a key factor affecting crop yield and quality. Traditional irrigation methods often have many problems and cannot meet the needs of modern agriculture for precise and efficient management.

[0003] In the existing irrigation process, impurities in fertilizers, undissolved particles, and silt in water are easily accumulated in pipes, nozzles, and other parts, causing blockages. Many existing irrigation equipment lack effective anti-blockage measures. For example, nozzle blockage will cause uneven irrigation, and local areas cannot be irrigated normally, affecting the growth of crops. On the one hand, when the pipeline is seriously blocked, it may be necessary to replace the pipeline, causing economic losses and interruption of irrigation operations. For irrigation equipment that needs to fully mix fertilizers and water, the design of its stirring mechanism is often not perfect. Uneven stirring will lead to inconsistent concentrations of water-fertilizer solutions, affecting the fertilization effect. On the other hand, some stirring devices cannot effectively turn over the fertilizer and water at the bottom during the stirring process, and precipitation is easily formed, so that the fertilizer at the bottom cannot be fully dissolved and mixed, reducing the utilization rate of the fertilizer. It may also cause hidden dangers of pipeline blockage. When the stirring device fails, the stirring device cannot be replaced and maintained in time, thereby affecting subsequent work.

[0004] In view of this, the purpose of the present invention is to provide an irrigation device for accurately managing water and fertilizer in dryland farmland to solve the deficiencies in the prior art. Summary of the invention

[0051] Specifically, after the processed water and fertilizer enter into the spray pipe 602 through the feed pipe 603 corresponding to the feed port 507 , the farmland is evenly irrigated through the multiple irrigation ports 604 .

[0052] In addition, the present invention also provides a method for accurately managing water and fertilizer in dryland farmland irrigation equipment, comprising the following steps:

[0053] S1. Pour the fertilizer needed for irrigation into the feed pipe 202 through the feed hopper 201, start the vibration motor 203, and its output end drives the feed pipe 202 to vibrate, so that the fertilizer slides smoothly into the storage tank 1, and at the same time, introduce a proper amount of water into the storage tank 1 through the water inlet 204;

[0054] S2, the first motor 401 drives the rotating rod 402 to rotate, and the multiple first stirring blades 403 on the upper half of the rotating rod 402 stir the fertilizer and water to make the two mixed initially, and the multiple rotating drums 404 on the lower half of the rotating rod 402 rotate along with it, and the second stirring blades 405 at both ends of the rotating drum 404 turn the mixed fertilizer at the bottom upwards to enhance the stirring effect;

[0055] S3, after stirring, the filter screen 408 can filter out larger particles of impurities, the valve handle 413 is turned to open the first valve 412, and the water and fertilizer are transported to the irrigation mechanism 6 through the delivery pipe 411. The delivery amount can be controlled by adjusting the first valve 412;

[0056] S4, the second motor 504 drives the spray head 503 to rotate, and the external water source enters through the water bucket 502, and then sprays out from the spray head 503. Under the action of centrifugal force, it sprays around through multiple water pipes 505 and water spray ports 506 to clean the feed port 507 to prevent fertilizer residue from clogging the feed port 507;

[0057] S5, water and fertilizer flow into the nozzle 602 and are uniformly sprayed out from the irrigation port 604 at the bottom of the nozzle 602 to irrigate the dryland farmland. The irrigation time and range can be reasonably controlled to ensure that the water and fertilizer evenly cover the farmland;

[0058] S6. The staff member holds the handle 306 in the replacement mechanism 3 and rotates the blocking door 305 to rotate it outward around the first rotating shaft 304 to open it. Then, the stirring device slides the slide plate 303 along the slide groove 302 of the long board 301 to take out the stirring device as a whole, thereby completing the replacement of the stirring device.

[0059] Working principle: When the present invention is used, it specifically includes the following steps:

[0060] First, the device is started, and the feed hopper 201 is used to put fertilizer. The output end of the vibration motor 203 drives the feed pipe 202 to vibrate, so that the fertilizer can pass through the feed pipe 202 more smoothly into the storage tank 1. At the same time, water can be sent into the storage tank 1 through the water inlet 204, realizing the initial feeding process of fertilizer and water.

[0061] Next, in actual work, the first motor 401 drives the rotating rod 402 to rotate, so that the multiple first stirring blades 403 on the upper half of the rotating rod 402 fully stir and mix the fertilizer and water in the storage tank 1 to make the water and fertilizer uniform, and then the multiple rotating drums 404 on the lower half of the rotating rod 402 rotate accordingly, and then the second stirring blades 405 at both ends of the rotating drum 404 turn over the mixed fertilizer at the bottom, so that it re-enters the stirring and mixing work, further enhancing the stirring effect, ensuring that the water and fertilizer are mixed more thoroughly, and stirring. During the mixing process, part of the mixed water and fertilizer enters the feed tank 407 through the filter screen 408. The filter screen 408 can filter out larger particles of impurities to prevent the conveying pipe 411 from being blocked. When the water and fertilizer in the storage tank 1 needs to be conveyed to the feed tank 407, the baffle 409 is driven downward by the second rotating shaft 410 to allow the filtered water and fertilizer to enter the feed tank 407. Then, by rotating the valve hand 413, the first valve 412 is opened, and the water and fertilizer can be conveyed to the next stage through the conveying pipe 411.

[0062] In actual work, water is sent into the water pipe 505 through the water bucket 502, and the second motor 504 rotates to drive the spray head 503 to rotate, so that water is sprayed out along with the spray head 503. Under the action of centrifugal force, the water is sprayed around through multiple water pipes 505 and water spray ports 506 to clean the feed port 507 to prevent fertilizer residue from clogging the feed port 507. Then, by opening the second valve 509, the cleaned water is discharged through multiple water outlet pipes 508, effectively preventing the feed port 507 from being blocked.

[0063] In the actual operation process of the present invention, water and fertilizer are transported from the feed port 507 to the feed pipe 603, then enter the nozzle 602, and finally uniformly sprayed out from the irrigation port 604. Through the multiple irrigation ports 604, uniform irrigation of dryland farmland is achieved. When the stirring device needs to be replaced, the staff can hold the handle 306, and then rotate the baffle 305 to make the baffle 305 rotate outward around the first rotating shaft 304 to open, and then the stirring device can slide the slide plate 303 along the slide groove 302 of the long board 301, so as to take out the stirring device as a whole for replacement or maintenance. The operation is simple and fast, and the work efficiency is improved. Through the various mechanisms in the present invention, accurate management and irrigation of water and fertilizer in dryland farmland is achieved, the efficiency and stability of the irrigation process are guaranteed, and problems such as blockage are avoided, the utilization efficiency of water and fertilizer is effectively improved, and the growth of crops in dryland farmland is promoted.
