Description

Technical Field

[0001] This invention relates to the field of irrigation equipment technology, specifically to an integrated water and fertilizer irrigation device for greenhouses. Background Technology

[0002] A greenhouse, also known as a polytunnel, is a facility used for growing plants. It typically has a transparent covering material to provide light and can regulate environmental factors such as temperature, humidity, light intensity, and gas composition. Greenhouse technology is widely used in agricultural planting, scientific research, and ornamental plant display, which can improve crop yield and quality. Integrated water and fertilizer management is a technology that combines irrigation and fertilization. It supplies crops with the water and fertilizer they need through a pipeline system on a timed and quantitative basis, improving fertilizer utilization, saving water resources, increasing crop yield and quality, and reducing environmental pollution and production costs.

[0003] According to patent document CN220935670U, a water-fertilizer integrated irrigation device for easy and thorough mixing includes a main body and a mixing component. The main body has casters at its bottom and a water inlet on its upper left side. The mixing component, located inside the main body, includes a servo motor, a sun gear, planetary gears, a stirring rod, a conveying frame, a drive motor, and a threaded rotating rod. The servo motor has a sun gear connected to its front end, and planetary gears are connected to the outside of the sun gear. A stirring rod is installed at the lower end of the sun gear. A conveying frame is located on the upper right side of the main body, and a drive motor is installed on the right side of the conveying frame. This water-fertilizer integrated irrigation device, through the mixing component, avoids the problem of uneven fertilizer-water mixing common in many irrigation devices, which leads to inconsistent pesticide absorption by crops during irrigation, thus improving the overall efficiency of the irrigation device.

[0004] In the process of using the aforementioned patent, when applying fertilizer, some fertilizer tends to clump due to its high solubility and high moisture content. Furthermore, because the fertilizer is not applied in a dispersed manner, uneven mixing with water can still occur, resulting in uneven fertilizer content in the mixture absorbed by crops. To further improve the efficiency of thorough mixing of water and fertilizer, a water and fertilizer integrated irrigation device for greenhouses is now provided, which can eliminate the drawbacks of existing devices.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In one embodiment, such as Figures 1-7 As shown, an integrated water and fertilizer irrigation device for greenhouses includes a tank 1, a discharge pipe 7 installed at the bottom of the tank 1, an irrigation component installed at the end of the discharge pipe 7 away from the tank 1, an electric valve installed at the bottom of the inner wall of the tank 1, the electric valve being electrically connected to an external controller via a wire, a top cover 4 installed at the top of the tank 1, a conveying pipe 5 and a water conveying pipe 6 arranged above the top cover 4, the conveying pipe 5 being located at one end of the water conveying pipe 6, and a stirring mechanism for fully mixing clean water and fertilizer on the tank 1.

[0040] The stirring mechanism includes: a connecting bottom plate 207 disposed inside the tank 1, and two arc-shaped scrapers 206 symmetrically fixedly connected to the top of the connecting bottom plate 207, both of which are in contact with the inner wall of the tank 1.

[0041] The stirring mechanism also includes: a stirring component disposed inside the tank 1;

[0042] The stirring assembly includes: two second spiral stirring rods 205 symmetrically rotatably connected to the top of the connecting base plate 207, the two second spiral stirring rods 205 being located between two arc-shaped scrapers 206, and a first spiral stirring rod 204 fixedly connected to the top of the connecting base plate 207, the first spiral stirring rod 204 being located between the two second spiral stirring rods 205;

[0043] A connecting assembly is provided on the first spiral stirring rod 204;

[0044] The top cover 4 is equipped with a dispensing mechanism for grinding and evenly dispensing fertilizer;

[0045] In this embodiment, during use, clean water can be transported into the inner cavity of the tank 1 through the stirring mechanism and the water supply pipe 6, which allows for convenient delivery of clean water and control of the fertilizer concentration in the clean water. Then, the stirring mechanism drives the first spiral stirring rod 204 to stir the clean water and fertilizer and scrape the inner wall of the tank 1, which can prevent some fertilizer from adhering to the inner wall of the tank 1 during the stirring and mixing process. During this process, the stirring mechanism can cause the two second spiral stirring rods 205 to move and rotate around the first spiral stirring rod 204 as the axis, which can efficiently stir the clean water and fertilizer.

[0046] When fertilizer is fed into the inner cavity of tank 1 through conveying pipe 5, the fertilizer can be ground by the cooperation of stirring mechanism and feeding mechanism. After grinding, the fertilizer is evenly fed into the inner cavity of tank 1, which can further improve the efficiency of mixing water and fertilizer and effectively avoid blockage caused by some fertilizer clumping, which would prevent subsequent fertilizer from being fed.

[0047] After the water and fertilizer are mixed, the electric valve is opened by the external controller, and the water and fertilizer mixture is transported through the discharge pipe 7 and the irrigation components, so that the crops can be irrigated in the greenhouse.

[0048] In one embodiment, such as Figures 1-7 As shown, the connecting assembly includes: a drain pipe 2015 fixedly connected to the top end of the first spiral stirring rod 204, the drain pipe 2015 extending to the outside of the top end of the top cover 4, the drain pipe 2015 being rotatably connected to the top cover 4, a second connecting ring 2010 fixedly connected to the top end of the drain pipe 2015, a limiting rotating ring 2013 fixedly connected to the top end of the second connecting ring 2010, the limiting rotating ring 2013 having a T-shaped vertical cross-section, a first connecting ring 201 provided on the upper surface of the second connecting ring 2010, the first connecting ring 201 slidingly sleeved on the outer wall of the limiting rotating ring 2013, and the first connecting ring 201 located at the bottom end of the water supply pipe 6. The first connecting ring 201 is fixedly connected to the water supply pipe 6. Two drain outlets 2014 are symmetrically opened on the outer wall of the drain pipe 2015. The inner walls of the two drain outlets 2014 that are close to each other are both inclined. The water supply pipe 6, the first connecting ring 201, the second connecting ring 2010, the drain outlets 2014 and the inner cavity of the drain pipe 2015 are all interconnected. Through the cooperation of the first connecting ring 201, the second connecting ring 2010 and the limiting rotating ring 2013, the water supply pipe 6 can be prevented from rotating synchronously with the drain pipe 2015 during the rotation of the drain pipe 2015, thereby effectively preventing adverse effects on the delivery of clean water.

[0049] A drive assembly is installed on the drain pipe 2015;

[0050] In one embodiment, such as Figures 1-6 As shown, the drive assembly includes: a bevel ring 202 fixedly connected to the outer wall of the drain pipe 2015, the bevel ring 202 being located above the top cover 4, a bevel gear 2011 meshing with the outer wall of the bevel ring 202, a dual-head motor 2012 being provided at one end of the bevel gear 2011 away from the bevel ring 202, the dual-head motor 2012 being mounted on the top of the top cover 4, and one output end of the dual-head motor 2012 being fixedly connected to the bevel gear 2011;

[0051] A support assembly is installed on the drain pipe 2015;

[0052] The support assembly is a support turntable 208 fixedly connected to the outer wall of the drain pipe 2015. The support turntable 208 is located inside the tank 1. The support turntable 208 is sleeved on the outer wall of the two second spiral stirring rods 205. Both second spiral stirring rods 205 are rotatably connected to the support turntable 208.

[0053] A transmission assembly is provided on the support turntable 208;

[0054] The transmission assembly includes: a fixed gear ring 209 disposed above the support turntable 208, the fixed gear ring 209 being fixedly connected to the top cover 4, and two spur gears 203 being symmetrically meshed on the outer wall of the fixed gear ring 209. The two spur gears 203 are respectively located at the top ends of the two second spiral stirring rods 205, and the two spur gears 203 are respectively fixedly connected to the two second spiral stirring rods 205. Through the mutual cooperation of the drive assembly, the support assembly, and the transmission assembly, the two second spiral stirring rods 205 can be displaced and rotated around the first spiral stirring rod 204 as the axis, so as to achieve the purpose of efficient mixing of water and fertilizer.

[0055] In one embodiment, such as Figures 1-4 As shown, the feeding mechanism includes: a grinding assembly installed on the feeding pipe 5;

[0056] The grinding assembly includes: a grinding box 305 fixedly connected to the bottom end of the feed pipe 5, the grinding box 305 being fixedly connected to the top cover 4, the grinding box 305 being located at the end of the dual-head motor 2012 away from the bevel gear 2011, the dual-head motor 2012 being mounted on the outer wall of the grinding box 305, a grinding roller 304 being rotatably connected inside the grinding box 305, the grinding roller 304 being fixedly connected to the other output end of the dual-head motor 2012, the inner cavity of the grinding box 305 communicating with the inner cavity of the feed pipe 5, and a grinding groove formed inside the grinding box 305 for accommodating the grinding roller 304. Through the cooperation between the grinding groove and the grinding roller 304, the blockage caused by the clumping of some fertilizer can be prevented, thus preventing the subsequent fertilizer from being conveyed.

[0057] The grinding box 305 is equipped with a material conveying assembly;

[0058] In one embodiment, such as Figures 2-6 As shown, the material conveying assembly includes:

[0059] A feeding pipe 301 is fixedly connected to the bottom of the grinding box 305. The feeding pipe 301 passes through the top cover 4 to the inside of the tank 1. A support ring 302 is fixedly connected to the outer wall of the feeding pipe 301. A fixed slip ring 307 is integrally formed on both the inner and outer walls of the support ring 302. The inner cavity of the feeding pipe 301 is interconnected with the inner cavity of the grinding box 305.

[0060] A feeding assembly is provided on the support ring 302;

[0061] The feeding assembly includes a feeding rotating ring 303 that is slidably sleeved on the outer wall of the support ring 302. The feeding rotating ring 303 is slidably connected to the fixed sliding ring 307. The feeding rotating ring 303 is located on the outside of the support turntable 208 and is fixedly connected to the support turntable 208. Multiple feeding slots 306 are equidistantly opened on the bottom end of the feeding rotating ring 303. The inner walls of the multiple feeding slots 306 are all frustoconical. Through the cooperation of the conveying assembly and the feeding assembly, fertilizer can be evenly fed into the inner cavity of the tank 1, thereby effectively improving the mixing efficiency of water and fertilizer.

[0062] The above embodiment discloses an integrated water and fertilizer irrigation device for greenhouses. In use, clean water is transported to the inner cavity of the drain pipe 2015 through the water supply pipe 6, the first connecting ring 201, and the second connecting ring 2010. Then, the clean water can enter the inner cavity of the tank 1 through the drain outlet 2014. This allows for convenient delivery of clean water and enables control of the fertilizer concentration in the clean water during the stirring process.

[0063] Then, the dual-head motor 2012 is started, which drives the bevel gear 2011 to rotate through one output end. At this time, the bevel gear ring 202 drives the drain pipe 2015 to rotate under the meshing drive of the bevel gear 2011. At the same time, the limiting rotating ring 2013 rotates along the inner wall of the first connecting ring 201 through the second connecting ring 2010 under the drive of the drain pipe 2015. At this time, the first spiral stirring rod 204 and the support turntable 208 rotate synchronously under the drive of the drain pipe 2015. At the same time, the connecting bottom plate 207 drives the two arc-shaped scrapers 206 to scrape the inner wall of the tank 1 under the drive of the first spiral stirring rod 204. This can prevent some fertilizer from adhering to the inner wall of the tank 1 during the mixing process.

[0064] During this process, the two second spiral stirring rods 205 are driven by the connecting base plate 207 and the supporting turntable 208 to move around the first spiral stirring rod 204 as the axis. At this time, the spur gear 203 is driven by the second spiral stirring rod 205 to mesh with the fixed gear ring 209, so that the second spiral stirring rod 205 can rotate while moving, thereby efficiently stirring the water and fertilizer.

[0065] At this time, the feeding rotating ring 303 rotates along the outer wall of the support ring 302 and the fixed slip ring 307 under the drive of the support turntable 208. At the same time, the grinding roller 304 rotates inside the grinding box 305 under the drive of the double-head motor 2012 through another output end. When fertilizer is conveyed into the grinding box 305 through the conveying pipe 5, the grinding roller 304 can grind the fertilizer, thereby effectively avoiding the clumping of some fertilizer.

[0066] When the ground fertilizer passes through the grinding box 305 and the feeding pipe 301 into the inner cavity of the feeding ring 303, the multiple feeding troughs 306, driven by the feeding ring 303, move the granular fertilizer in the inner cavity of the feeding trough 306. During this process, the centrifugal force of the feeding ring 303 can evenly distribute the granular fertilizer in the inner cavity of the feeding trough 306 into the inner cavity of the tank 1, thereby further improving the efficiency of fully mixing water and fertilizer.

[0067] After the water and fertilizer are mixed, the electric valve is opened by the external controller, and the water and fertilizer mixture is transported through the discharge pipe 7 and the irrigation components, so that the crops can be irrigated in the greenhouse.

[0068] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
