Description

Technical Field

[0001] This invention relates to the field of crop irrigation, and more specifically, to a mobile sprinkler irrigation water and fertilizer precision control device. Background Technology

[0002] With the adjustment of agricultural structure, irrigation and fertilization are gradually developing towards automation, greatly reducing manual labor. my country is a major agricultural country with farmland widely distributed throughout its provinces. Irrigation and fertilization are necessary during crop cultivation. To improve work efficiency during irrigation, a water-fertilizer integrated machine has been designed to mix clean water and fertilizer. This water-fertilizer integrated irrigation machine is a modern agricultural device that integrates irrigation and fertilization. It aims to achieve synchronous supply and precise management of water and nutrients through an intelligent control system. At the same time, the water-fertilizer integrated irrigation machine can reasonably control the irrigation volume, reduce the loss of chemical fertilizers and pesticides with water, and reduce the risk of pollution to groundwater and water bodies.

[0003] During long-term storage and stockpiling, fertilizers may accumulate large solid particles due to compression. In existing integrated water and fertilizer irrigation systems, these larger solid particles cannot be completely dissolved, leading to sediment formation during subsequent mixing. This sediment flows through the pipes during spraying and eventually accumulates at the outlet, causing blockages. Solving these problems is a pressing issue for those skilled in the art. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a mobile sprinkler irrigation water and fertilizer precision control device, which aims to solve the problem that large solid particles clump into the interior of the integrated machine, causing the particles to be unable to be dissolved and clogging the outlet in subsequent processes.

[0005] This invention is implemented as follows:

The push rod is fixedly connected to the outer wall of the screen, and the connecting piece is installed at the end of the push rod away from the screen. The U-shaped tube is fixedly connected to the outer wall of the funnel. The outer rod is fixedly connected to the outer wall of the screen. The output rod is located inside the funnel. The actuating plate is fixedly connected to the bottom of the output rod. The spring push rod is located inside the funnel. The striking pad is fixedly connected to the inner wall of the funnel. The slide rail is opened inside the funnel. The slider is fixedly connected to the outer wall of the screen.

[0011] Preferably, the bottom of the inner wall of the silo is concave from all sides to the center, the bottom of the fertilizer tank is fixedly connected to an output pipe and communicates with a funnel, the inner wall of the funnel is fixedly connected to a guide plate, and the top of the screening screen is fixedly connected to the bottom of the guide plate.

[0012] By adopting the above technical solution, the fertilizer entering the bottom silo will flow under the action of the inclined inner wall of the bottom silo, assisting the fertilizer conveying pump to transport the fertilizer. The presence of the guide plate can ensure that the fertilizer accumulates on the top of the screening screen through the output pipe.

[0013] Preferably, the outer wall of the screening screen is slidably connected to the inner wall of the funnel, and the slider is located inside the slide rail and is slidably connected to the inner wall of the slide rail.

[0014] By adopting the above technical solution, when the screening screen slides inside the funnel, it can drive the slider to slide inside the slide rail. At the same time, the slider and the slide rail can support the screening screen.

[0015] Preferably, the end of the push rod away from the screening screen passes through the funnel and extends to the outside of the funnel. The outer wall of the push rod is slidably connected to the inner wall of the funnel through which it passes. The two ends of the traction rod are rotatably connected to the outer wall of the rotating plate and the connecting piece, respectively.

[0016] By adopting the above technical solution, when the rotating plate rotates under the action of the motor, the screening screen can be driven to shake through the traction rod, connecting parts and push rod.

[0018] By adopting the above technical solution, the screening mesh can push the outer rod to slide inside the U-shaped tube when it moves.

[0019] Preferably, one end of the output rod passes through the funnel and extends into the interior of the U-shaped tube, and the outer wall of the output rod is slidably connected to the inner wall of the U-shaped tube.

[0020] By adopting the above technical solution, when the outer rod slides, the output rod will slide under the action of the air pressure inside the U-shaped tube.

[0021] Preferably, the bottom of the actuating plate has a serrated design, and the bottom of the actuating plate contacts the top of the screening screen.

[0022] By adopting the above technical solution, when the output rod moves, it can push the actuating plate to move on top of the screening screen, thereby spreading the material piled on top of the screening screen.

[0023] Preferably, the spring push rod is located on the left front and back sides of the screening mesh and the right front and back sides of the screening mesh, and is fixedly connected to the outer wall of the screening mesh.

[0024] By adopting the above technical solution, when the screening screen moves, it can push the spring push rod to move and collide with the striking pad. The impact force generated by the collision can assist the fertilizer inside the bottom hopper to flow.

[0025] The beneficial effects of this invention are:

[0026] 1. By installing a screening screen and a toggle plate inside the fertilizer supply component and controlling the motor operation, the screening screen will shake, causing the material accumulated on top of the screening screen to roll. This allows the material to be filtered through different positions on the screening screen, accelerating the filtration effect of the screening screen on the fertilizer. At the same time, the presence of the screening screen also prevents larger particle clumps from entering the bottom chamber, ensuring that the fertilizer inside the mixing tank is fully mixed with the liquid. This solves the problem that existing large solid particle clumps would enter the integrated machine, causing the particle clumps to not be dissolved and block the outlet in subsequent processes.

[0027] 2. By employing UAV multispectral technology to capture multispectral images of crops, and using sensor technology to monitor crop environmental information, the system analyzes crop growth and soil nutrients, establishes a fertilization decision model based on crop growth and soil nutrients, optimizes the amount of water and fertilizer required for different growth stages of crops in real time, allocates appropriate fertilizer concentrations to crops in different regions, avoids excessive or insufficient fertilization, improves irrigation efficiency, reduces manual labor, and is highly intelligent.

[0047] The water and fertilizer mixing control system includes: water supply component 6, fertilizer supply component 8, and fertilizer mixing component 7; the mobile sprinkler irrigation system includes: mobile sprinkler irrigation machine 3.

[0048] The water supply assembly 6 includes a water tank 601, a water pump 602, a water delivery pipe 603, and a water meter 604. The water tank 601 is fixedly connected to the inside of the outer casing 1, the water pump 602 is fixedly connected to the bottom of the water tank 601, the water delivery pipe 603 is installed at the output end of the water pump 602, and the water meter 604 is fixedly connected to the outer wall of the water delivery pipe 603. The water supply assembly 6 is used to deliver liquid to the inside of the fertilizer mixing assembly 7.

[0049] The fertilizer mixing assembly 7 includes a mixing tank 701 and a mixing pump 702. The mixing tank 701 is fixedly connected to the inside of the outer casing 1, and the mixing pump 702 is fixedly connected to the top of the mixing tank 701. The fertilizer mixing assembly 7 is used to mix fertilizer with liquid.

[0050] The fertilizer supply assembly 8 includes a fertilizer tank 801, a fertilizer filter assembly 802, and a fertilizer delivery pump 803. The fertilizer tank 801 is fixedly connected to the inside of the outer shell 1. The fertilizer filter assembly 802 is located below the fertilizer tank 801. The fertilizer delivery pump 803 is fixedly connected to the bottom of the fertilizer filter assembly 802. The fertilizer supply assembly 8 is used to deliver the filtered fertilizer to the inside of the fertilizer mixing assembly 7.

[0051] The fertilizer filter assembly 802 consists of a bottom chamber 8021, a funnel 8022, a support plate 8023, a motor 8024, a screening screen 8025, a rotating plate 8026, a traction rod 8027, a push rod 8028, a connector 8029, a U-shaped tube 80210, an outer rod 80211, an output rod 80212, a toggle plate 80213, a spring push rod 80214, a striking pad 80215, a slide rail 80216, and a slider 80217. The bottom chamber 8021 is fixedly connected to the inside of the outer casing 1. The funnel 8022 is fixedly connected to the top of the bottom chamber 8021. The support plate 8023 is fixedly connected to the top of the funnel 8022. The motor 8024 is fixedly connected to the top of the support plate 8023. The screening screen 8025 is installed inside the funnel 8022. The rotating plate 8026 is installed on the motor. At the output end of 8024, the traction rod 8027 is installed on the outer wall of the rotating plate 8026, the push rod 8028 is fixedly connected to the outer wall of the screening screen 8025, the connecting piece 8029 is installed on the end of the push rod 8028 away from the screening screen 8025, the U-shaped tube 80210 is fixedly connected to the outer wall of the funnel 8022, the outer rod 80211 is fixedly connected to the outer wall of the screening screen 8025, the output rod 80212 is set inside the funnel 8022, the actuating plate 80213 is fixedly connected to the bottom of the output rod 80212, the spring push rod 80214 is set inside the funnel 8022, the striking pad 80215 is fixedly connected to the inner wall of the funnel 8022, the slide rail 80216 is opened inside the funnel 8022, and the slider 80217 is fixedly connected to the outer wall of the screening screen 8025.

[0052] It should be noted that the bottom inner wall of the bottom hopper 8021 is concave from all sides towards the center. Fertilizer entering the bottom hopper 8021 will flow under the influence of the inclined inner wall, assisting the fertilizer transport pump 803 in transporting the fertilizer. An output pipe is fixedly connected to the bottom of the fertilizer tank 801 and communicates with the funnel 8022. A guide plate is fixedly connected to the inner wall of the funnel 8022. The top of the screening screen 8025 is fixedly connected to the bottom of the guide plate. The presence of the guide plate ensures that fertilizer accumulates on top of the screening screen 8025 through the output pipe. The outer wall of the screening screen 8025 is slidably connected to the inner wall of the funnel 8022. The slider 80217 is located inside the slide rail 80216 and is slidably connected to the inner wall of the slide rail 80216. When the screening screen 8025 slides inside the funnel 8022, it can drive the slider 80217 to slide inside the slide rail 80216. Simultaneously, the slider 80217 and slide rail 80216 cooperate to support the screening screen 8025. One end of the push rod 8028, away from the screening screen 8025, passes through the funnel 8022 and extends to the outside of the funnel 8022. The outer wall of the push rod 8028 is slidably connected to the inner wall of the funnel 8022 through which it passes. Both ends of the traction rod 8027 are rotatably connected to the outer wall of the rotating plate 8026 and the connecting piece 8029, respectively. When the rotating plate 8026 rotates under the action of the motor 8024, it can be driven by the traction rod 8027, the connecting piece 8029, and the push rod 8028. The screen 8025 shakes, and the end of the outer rod 80211 away from the screen 8025 passes through the funnel 8022 and extends into the U-shaped tube 80210. The outer wall of the outer rod 80211 is slidably connected to the inner wall of the U-shaped tube 80210. When the screen 8025 moves, it can push the outer rod 80211 to slide inside the U-shaped tube 80210. One end of the output rod 80212 passes through the funnel 8022 and extends into the U-shaped tube 80210. The outer wall of the output rod 80212 is slidably connected to the inner wall of the U-shaped tube 80210. When the outer rod 80211 slides, the output rod 80212 will slide under the action of the air pressure inside the U-shaped tube 80210. The actuating plate 80... The bottom of 213 has a serrated design. The bottom of the actuating plate 80213 contacts the top of the screening screen 8025. When the output rod 80212 moves, the serrated actuating plate 80213 moves on the top of the screening screen 8025, which can spread the material piled on the top of the screening screen 8025. The spring push rod 80214 is located on the left front and back and right front and back of the screening screen 8025, and is fixedly connected to the outer wall of the screening screen 8025. When the screening screen 8025 moves, it can push the spring push rod 80214 to move and collide with the striking pad 80215. The impact force generated by the collision can assist the flow of fertilizer inside the bottom hopper 8021.

[0053] By setting a screening screen 8025 inside the fertilizer supply assembly 8 and controlling the motor 8024 to operate, the motor 8024 drives the rotating plate 8026 to rotate. Since the two ends of the traction rod 8027 are connected to the rotating plate 8026 and the connecting piece 8029 respectively, when the rotating plate 8026 rotates, the traction rod 8027 will drive the push rod 8028 to move back and forth through the connecting piece 8029. At this time, the push rod 8028 will drive the screening screen 8025 to slide back and forth inside the funnel 8022. At this time, the fertilizer accumulated on the top of the screening screen 8025 will roll under the inertia generated during the movement of the screening screen 8025 and be screened through different areas of the screening screen 8025, thereby speeding up the speed at which the fertilizer passes through the screening screen 8025 and improving the screening efficiency of the screening screen 8025.

[0054] By installing a U-shaped tube 80210 on the outer wall of the funnel 8022, when the screening screen 8025 shakes, it will drive the outer rod 80211 to slide inside the U-shaped tube 80210 and apply pressure to the air inside the U-shaped tube 80210. When the pressure inside the U-shaped tube 80210 changes, the output rod 80212 will drive the actuating plate 80213 to reciprocate on the top of the screening screen 8025 under the action of air pressure, and the movement trajectory is opposite to that of the screening screen 8025. At this time, the screening screen 8025 can spread the fertilizer accumulated on the top of the screening screen 8025 evenly, so that the fertilizer cannot accumulate on the top of the screening screen 8025, thus ensuring the shaking screening effect of the screening screen 8025 on the fertilizer.

[0055] By installing a spring push rod 80214 and a striking pad 80215 inside the funnel 8022, when the screening screen 8025 reciprocates inside the funnel 8022, one end of the spring push rod 80214 will collide with the striking pad 80215. The impact force generated by the impact will be transmitted through the funnel 8022 to the inside of the bottom hopper 8021. Since the inner wall of the bottom hopper 8021 is concave from both sides to the center, the fertilizer that has been screened inside the bottom hopper 8021 will move along the inclined inner wall under the force of the impact, assisting the fertilizer conveying pump 803 in conveying the fertilizer.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
