Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation, and in particular to a smart agricultural water-saving irrigation and fertilization device. Background Art

[0002] Planting is one of the main components of agriculture, including the cultivation of crops such as wheat, rice, corn, cotton, oil crops, sugar crops, vegetables, and fruits. In traditional agriculture, irrigation and fertilization have always been key links in agricultural production. However, traditional methods often lead to water waste and low fertilizer utilization due to problems such as extensive irrigation methods and uneven fertilization. In recent years, with the continuous development of smart agricultural technology, a new type of water-saving irrigation and fertigation technology has emerged. This technology installs multiple nozzles on the pipeline and equips it with control valves to accurately control the amount of water, so that fertilizer can be evenly sprayed onto the seedlings with the water flow. In addition, tracks are installed in the greenhouse, and the pipeline moves along the tracks to achieve comprehensive fertilization of the seedlings. In modern agricultural irrigation and fertilization practices, although water-soluble fertilizers can be sprayed onto the surface of seedlings through nozzles on pipes, this method has certain limitations. Part of the water-soluble fertilizers sprayed onto the seedlings only adhere to the surface of the seedling leaves or stems, and fail to directly act on the root system. Since water-soluble fertilizers are fast-acting and have a short lasting effect, if they are not absorbed by crops in time, some nutrients will easily volatilize, resulting in waste of water-soluble fertilizers and reducing fertilizer utilization.

[0003] In order to solve the above problems, this application proposes a smart agricultural water-saving irrigation and fertilization device. Summary of the Invention

[0004] The present invention proposes an intelligent agricultural water-saving irrigation and fertilization device, which solves the problem in related technologies that part of the water-soluble fertilizer sprayed on the seedlings only adheres to the surface of the seedling leaves or stems, but fails to directly act on the root system. Since the water-soluble fertilizer has strong fast-acting properties and a short lasting effect, if it is not absorbed by the crops in time, some nutrients will easily volatilize, resulting in waste of water-soluble fertilizer and reduced fertilizer utilization rate.

[0005] The present invention proposes a smart agricultural water-saving irrigation and fertilization device, which includes an irrigation box, a slide rail, an irrigation component, a self-propelled stirring component, a scraping and blowing component, and a cartridge filter element: The irrigation box is arranged on two slide rails, the cartridge filter is arranged in the irrigation box, and the irrigation assembly is installed on one side of the irrigation box and is in communication with the interior thereof for spraying water and fertilizer on crops; The self-propelled stirring assembly includes a roller, a rod-type stirring member and a driving member.

One end of the hose is connected to one end of the scraper tube, and one end of the air guide pipe is connected to the inside of the cartridge filter element.

[0008] As a further optimization solution of the present invention, the cartridge filter element includes a filter cartridge and filter holes. The filter cartridge is horizontally installed in the irrigation box. The outer circumference of the filter cartridge is provided with densely arranged filter holes. The air duct is connected to the filter cartridge. A one-way valve is installed on the air duct to prevent liquid from entering the air duct.

[0009] As a further optimization solution of the present invention, the rod-type stirring member includes a stirring rod and a blade. The stirring rod is horizontally arranged in the filter cartridge. The two ends of the stirring rod respectively rotate through the two ends of the irrigation box. The two rollers are respectively installed at the two ends of the stirring rod. The driving member is used to drive the stirring rod to rotate.

[0010] As a further optimization solution of the present invention, the driving member includes a driven gear, a driving gear and a motor. The driven gear is fixed to one end of the stirring rod and is located between the irrigation box and the roller. The motor is installed on the top of one end of the irrigation box. The output end of the motor is connected to the driving gear that meshes with the driven gear.

[0011] As a further optimization solution of the present invention, the irrigation assembly includes a spraying member and a liquid guiding member. The spraying member is installed on the side of the irrigation box. The irrigation box is installed with a liquid guiding member that is connected to the interior of the irrigation box and guides the liquid into the spraying member.

[0012] As a further optimization solution of the present invention, the spraying member includes a mounting rod, a spraying pipe and a nozzle. A horizontally arranged spraying pipe is installed on the side of the irrigation box through the mounting rod. The bottom of the spraying pipe is connected to a plurality of nozzles arranged at intervals. The liquid guiding member is used to guide the liquid in the irrigation box into the spraying pipe.

[0013] As a further optimization solution of the present invention, the liquid guiding member includes a first water pump and a liquid guiding tube. The first water pump connected to the interior of the irrigation box is installed on the side thereof, the liquid outlet end of the first water pump is connected to the liquid guiding tube, and one end of the liquid guiding tube is connected to one end of the spraying pipe.

[0014] As a further optimization scheme of the present invention, the liquid supply assembly includes a liquid supply tank, a second water pump, a liquid supply pipe and an end cover. The liquid supply tank is installed on the top of the irrigation box. A second water pump connected to the interior of the liquid supply tank is installed on the side of the liquid supply tank. The liquid outlet end of the second water pump is connected to the liquid supply pipe, and one end of the liquid supply pipe is connected to the filter cartridge. A liquid inlet is opened on the top of the liquid supply tank, and the end cover is sealed in the liquid inlet.

[0015] The above technical solution of the present invention has the following beneficial technical effects: 1. The slide rail can be arranged along the length direction of the crop, and the driving member drives the rod-type stirring member to drive the roller to roll along the slide rail, and the irrigation box then slides along the slide rail. The water-soluble fertilizer can be sprayed on the crops through the irrigation assembly. When spraying water-soluble fertilizer on the crop seedlings, the distance between the scraping and blowing assembly and the irrigation box can be adjusted so that the scraping and blowing assembly contacts the upper part of the seedlings. When the irrigation box moves, the scraping and blowing assembly can scrape the water-soluble fertilizer droplets sprayed on the seedlings, so that the water-soluble fertilizer attached to the surface of the seedlings falls to the bottom of the seedlings, reducing the waste of water-soluble fertilizer. At the same time, the water-soluble fertilizer can act more directly on the root system of the seedlings and be fully absorbed by the crops, thereby improving the utilization rate of the water-soluble fertilizer; 2. When scraping water droplets of water-soluble fertilizer on the surface of the seedlings through the scraping and blowing assembly of the present invention, the air supply assembly can be used to guide the air into the scraping and blowing assembly. The scraping and blowing assembly blows the air directly toward the seedlings, scraping the seedlings while blowing the water-soluble fertilizer, further removing water droplets attached to the surface of the leaves and stems of the seedlings, allowing the water-soluble fertilizer to better act on the root system of the seedlings, and reducing the problem of nutrient volatilization caused by the strong fast-acting and short-lasting effect of the water-soluble fertilizer; 3. When irrigating and fertilizing the seedlings, the stirred water-soluble fertilizer is generally sprayed through the irrigation assembly. However, the water-soluble fertilizer is easy to precipitate during use, and if some particles melt slowly, the granular fertilizer will enter the irrigation assembly. The present invention directly guides the water-soluble fertilizer into the cartridge filter element through the liquid supply assembly, which can filter the unmelted particles in the water-soluble fertilizer, and then sprays it to the seedlings through the irrigation assembly, which can effectively prevent the particles from entering the irrigation assembly and causing blockage. When the driving member drives the rod-type stirring member to rotate and drive the roller to roll along the slide rail, the rod-type stirring member can stir the water-soluble fertilizer entering the cartridge filter element, thereby promoting the distribution of substances in the water-soluble fertilizer, so that the nutrients in the water-soluble fertilizer can evenly act on the seedlings, further reducing the risk of clogging of the irrigation assembly, ensuring the normal operation of the irrigation and fertilization system, and improving the quality and efficiency of irrigation and fertilization; 4. The present invention provides an air supply component, which can supply air to the scraping and blowing component at the same time and guide the gas into the cylindrical filter element, thereby generating bubbles in the water-soluble fertilizer and increasing the dissolved oxygen content in the water. At the same time, the stirring effect of the bubbles accelerates the dissolution process of the water-soluble fertilizer, so that the nutrients in the fertilizer are dissolved in the water more quickly. The stirring of the bubbles can further prevent the precipitation of solid particles in the water-soluble fertilizer and reduce the risk of pipeline blockage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0029] like Figure 1-11 As shown, the present invention proposes a smart agricultural water-saving irrigation and fertilization device, including an irrigation box 1, a slide rail 2, an irrigation component 3, a self-propelled stirring component 4, a scraping and blowing component 5 and a cartridge filter 6: The irrigation box 1 is set on two slide rails 2, the cartridge filter 6 is set in the irrigation box 1, and the irrigation assembly 3 is installed on one side of the irrigation box 1 and communicated with the interior thereof for spraying water and fertilizer on crops; The self-propelled stirring assembly 4 includes a roller 41, a rod-type stirring member 42 and a driving member 43. The rod-type stirring member 42 is arranged horizontally in the cylindrical filter element 6. The two ends of the rod-type stirring member 42 are respectively equipped with rollers 41 that roll with the two slide rails 2. The driving member 43 is used to drive the rod-type stirring member 42 to rotate and drive the rollers 41 to roll along the slide rails 2. The scraper and blower assembly 5 is installed at the bottom of the irrigation box 1, and the distance between the scraper and blower assembly 5 and the irrigation box 1 is adjustable. The air supply assembly 7 is installed at the bottom of the irrigation box 1, and the air supply assembly 7 ventilates the scraper and blower assembly 5 and the cartridge filter 6 respectively. When the irrigation box 1 moves along the slide rail 2, the scraper and blower assembly 5 moves with it and scrapes and blows the crops. A liquid supply assembly 8 for supplying liquid to the cartridge filter element 6 is mounted on the irrigation box 1 .

[0030] The irrigation box 1 is set on two slide rails 2, providing a mobile basic framework for the entire device, so that it can move in a specific direction in the farmland, facilitating comprehensive irrigation and fertilization of crops. The cartridge filter 6 is placed in the irrigation box 1 to filter impurities in the water-soluble fertilizer, ensuring the purity of the fertilizer solution entering the irrigation component 3, preventing pipe blockage, and ensuring smooth irrigation and fertilization. The irrigation component 3 is installed on the irrigation box 1 and connected to the box, responsible for spraying the treated water-soluble fertilizer onto the crops to achieve fertilization operation. The roller 41 of the self-propelled stirring component 4 rolls with the slide rail 2, and the rod stirring member 42 is in the cartridge filter 6. When the driving member 43 drives the rod stirring member 42 to rotate, it can drive the roller 41 to roll. The wheel 41 moves the irrigation box 1 and stirs the water-soluble fertilizer in the cylindrical filter element 6, promoting uniform distribution of the fertilizer, preventing precipitation and blockage, and improving the fertilization effect. The scraping and blowing assembly 5 is installed at the bottom of the irrigation box 1 and the distance is adjustable. During the movement of the irrigation box 1, the crops can be scraped and blown to shake off the water-soluble fertilizer attached to the surface of the seedlings to the bottom, which is beneficial to root absorption and reduces fertilizer waste. The air supply assembly 7 ventilates the scraping and blowing assembly 5 and the cylindrical filter element 6, enhancing the effect of removing water droplets of water-soluble fertilizer during scraping and blowing, increasing dissolved oxygen in the cylindrical filter element 6, accelerating fertilizer dissolution and preventing precipitation. The liquid supply assembly 8 supplies liquid to the cylindrical filter element 6 to ensure that the water-soluble fertilizer is filtered before irrigation and fertilization.

[0031] In this embodiment, the scraping and blowing assembly 5 includes an electric push rod 51, a scraping tube 52 and an air nozzle 53. The electric push rod 51 is installed at the bottom of the irrigation box 1. The driving end of the electric push rod 51 is connected to the scraping tube 52. The bottom of the scraping tube 52 is connected to a plurality of air nozzles 53 arranged at intervals. When the irrigation box 1 slides along the slide rail 2 and the water-soluble fertilizer is sprayed on the crops through the irrigation assembly 3, the distance between the scraping tube 52 and the crops can be adjusted by telescoping the electric push rod 51 so that the scraping tube 52 contacts the upper part of the seedling. In order to adapt to the needs of crops at different growth stages or varieties, when the irrigation box 1 is moved, the water-soluble fertilizer droplets sprayed on the seedlings can be scraped through the scraping tube 52, so that the water-soluble fertilizer attached to the surface of the seedlings is shaken off to the bottom. The multiple air nozzles 53 connected to the bottom of the scraping tube 52 can blow out the gas evenly when the air supply component 7 supplies air, and cooperate with the scraping action to effectively remove the water-soluble fertilizer droplets on the surface of the seedlings, so that the fertilizer can better act on the root system, improve the fertilizer utilization rate, and reduce the waste caused by the volatilization of the water-soluble fertilizer.

[0032] In this embodiment, the air supply assembly 7 includes an air pump 71, an air supply pipe 72, a diverter ball 73 and an air guide pipe 74. The air pump 71 is installed at the bottom of the irrigation box 1. The air outlet end of the air pump 71 is connected to the air supply pipe 72. The end of the air supply pipe 72 away from the air pump 71 is connected to the diverter ball 73. The diverter ball 73 is connected to the air guide pipe 74 and the hose 75. One end of the hose 75 is connected to one end of the scraper tube 52, and one end of the air guide pipe 74 is connected to the inside of the cartridge filter 6. The air pump 71 serves as the air supply source. , installed at the bottom of the irrigation box 1, the generated gas is transported to the diverter ball 73 through the air supply pipe 72, and the diverter ball 73 plays the role of distributing the gas. The gas is transported to the cylindrical filter element 6 through the air guide pipe 74, which increases the dissolved oxygen in the water, accelerates the dissolution of water-soluble fertilizer, and prevents the precipitation of solid particles. At the same time, the gas is sent to the scraping pipe 52 of the scraping and blowing assembly 5 through the hose 75, providing power for scraping and blowing, enhancing the effect of removing water-soluble fertilizer on the surface of the seedlings, and ensuring the efficient operation of the irrigation and fertilization device.

[0033] In this embodiment, the cartridge filter element 6 includes a filter cartridge 61 and filter holes 62. The filter cartridge 61 is installed horizontally in the irrigation box 1. The outer periphery of the filter cartridge 61 is provided with densely arranged filter holes 62. The air duct 74 is connected to the inside of the filter cartridge 61. A one-way valve is installed on the air duct 74 to prevent liquid from entering the air duct 74. The filter cartridge 61 is installed horizontally in the irrigation box 1. The densely arranged filter holes 62 on its outer periphery can effectively intercept unmelted particles in the water-soluble fertilizer and prevent these particles from entering the irrigation component 3 and causing blockage. The air duct 74 is connected to the inside of the filter cartridge 61 and is equipped with a one-way valve to ensure that gas can smoothly enter the filter cartridge 61 to generate bubbles, promote the dissolution and mixing of the water-soluble fertilizer, and prevent the liquid from flowing back into the air duct 74, thereby maintaining the normal working state of the device and ensuring the stability and reliability of irrigation and fertilization.

[0034] In this embodiment, the rod-type stirring member 42 includes a stirring rod 421 and a blade 422. The stirring rod 421 is horizontally arranged in the filter cartridge 61. The two ends of the stirring rod 421 rotate through the two ends of the irrigation box 1 respectively. Two rollers 41 are respectively installed at the two ends of the stirring rod 421. The driving member 43 is used to drive the stirring rod 421 to rotate; the driving member 43 includes a driven gear 431, a driving gear 432 and a motor 433. The driven gear 431 is fixed to one end of the stirring rod 421 and is located between the irrigation box 1 and the roller 41. The motor 433 is installed at the top of one end of the irrigation box 1. The output end of the motor 433 is connected to the driving gear 432 that meshes with the driven gear 431. After the motor 433 is started, it drives the driving gear 432 to rotate, driving the driven gear 431 to rotate, and then drives the stirring rod 421 to rotate. During the rotation process, the stirring rod 421 drives the roller 41 to roll on the slide rail 2, thereby realizing the movement of the irrigation box 1 and covering a wider range of irrigation and fertilization. On the other hand, the blades 422 on the stirring rod 421 fully stir the water-soluble fertilizer in the filter cartridge 61, accelerating the dissolution and uniform distribution of the fertilizer, reducing the risk of fertilizer precipitation, and improving the uniformity and effect of irrigation and fertilization.

[0035] In this embodiment, the irrigation assembly 3 includes a spraying member 31 and a liquid guiding member 32. The spraying member 31 is installed on the side of the irrigation box 1.

The spraying member 31 is installed on the side of the irrigation box 1 and is responsible for evenly spraying the water-soluble fertilizer onto the crops. The liquid guiding member 32 connects the interior of the irrigation box 1 and the spraying member 31. Under its action, the processed water-soluble fertilizer in the irrigation box 1 is transported to the spraying member 31, and the water-soluble fertilizer is sprayed onto the crops through the spraying member 31.

[0036] In this embodiment, the spraying member 31 includes a mounting rod 311, a spraying pipe 312, and a nozzle 313. The side of the irrigation box 1 is mounted with a horizontally arranged spraying pipe 312 via the mounting rod 311.

The liquid guiding member 32 is used to guide the liquid in the irrigation box 1 into the spraying pipe 312. The liquid guiding member 32 includes a first water pump 321 and a liquid guiding pipe 322. The first water pump 321 is mounted on the side of the irrigation box 1 and is connected to the interior of the irrigation box 1. The liquid outlet of the first water pump 321 is connected to the liquid guiding pipe 322. One end of the liquid guiding pipe 322 is connected to one end of the spraying pipe 312. The first water pump 321 is mounted on the side of the irrigation box 1 and is connected to the interior of the box. When activated, the first water pump 321 generates suction to draw in the water-soluble fertilizer in the irrigation box 1 and delivers it to the spray pipe 312 through the liquid conduit 322 connected to the liquid outlet. The nozzles 313 arranged at intervals at the bottom of the spray pipe 312 disperse the fertilizer solution into fine droplets and spray them onto the crops, thereby increasing the contact area between the fertilizer and the crops, improving the fertilization effect, and enabling the fertilizer to be more effectively absorbed and utilized by the crops, thereby promoting the growth and development of the crops.

[0037] In this embodiment, the liquid supply assembly 8 includes a liquid supply tank 81, a second water pump 82, a liquid supply pipe 83 and an end cover 84. The liquid supply tank 81 is installed on the top of the irrigation box 1, and a second water pump 82 connected to the interior of the liquid supply tank 81 is installed on the side of the liquid supply tank 81. The liquid outlet end of the second water pump 82 is connected to the liquid supply pipe 83, and one end of the liquid supply pipe 83 is connected to the filter cartridge 61. A liquid inlet is provided on the top of the liquid supply tank 81, and the end cover 84 is sealed in the liquid inlet; the liquid supply tank 81 is installed on the top of the irrigation box 1 to store water-soluble fertilizer solution, and the second water pump 82 installed on the side extracts the water-soluble fertilizer in the liquid supply tank 81 and transports it to the filter cartridge 61 through the liquid supply pipe 83.

This liquid supply method ensures that the water-soluble fertilizer can enter the filtration and irrigation fertilization process in an orderly manner, providing sufficient fertilizer supply for the continuous operation of the entire device.

[0038] The specific working principle of the present invention is as follows: First, the slide rail 2 is arranged along the length direction of the crop. The second water pump 82 of the liquid supply assembly 8 extracts water-soluble fertilizer from the liquid supply box 81 and transports it to the filter cartridge 61 of the cartridge filter element 6 through the liquid supply pipe 83.
