A cleaning and separation system for an integrated water and fertilizer surface irrigation system

Abstract

This invention discloses a cleaning and separation system for an integrated water and fertilizer surface irrigation system, relating to the field of cleaning and separation technology. It includes an integrated water and fertilizer irrigation device comprising a water storage tank, a pump, a sand and gravel filter, a water and fertilizer tank, an integrated water and fertilizer machine, and irrigation pipelines. A drive mechanism is installed on one side of the water storage tank, and an extension plate is installed inside the tank. During rainy weather, the drive mechanism is activated to move the extension plate out of the water storage tank. The design of the extension plate effectively increases the water-receiving area of ​​the water storage tank, reducing the amount of additional water needed for irrigation and making it more energy-efficient. When the extension plate moves out of the water storage tank, it synchronously drives a movable rod through a linkage mechanism, causing the movable rod to drive the main brush at the bottom of the movable plate and the fixed plate to clean the top of the top plate. This prevents garbage from accumulating on the top of the top plate and also prevents garbage from entering the water storage tank through the water inlet, reducing subsequent filtration steps and making it more energy-efficient and environmentally friendly.

Description

Technical Field

[0001] This invention relates to the field of cleaning and separation technology, specifically to a cleaning and separation system for an integrated water and fertilizer surface irrigation system. Background Technology

[0002] Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. It utilizes a pressure system (or natural terrain gradient) to mix soluble solid or liquid fertilizers, tailored to soil nutrient content and crop requirements, with irrigation water. This mixture is then supplied through a controllable pipeline system, allowing the water and fertilizer to blend. The resulting solution, delivered via pipes and drip emitters, forms a sprinkler or drip irrigation system, evenly, regularly, and quantitatively irrigating the crop's root zone. This ensures the soil around the main root system remains loose and has suitable moisture content. Furthermore, based on the specific nutrient requirements of different crops, soil conditions, nutrient content, and the water and fertilizer needs at different growth stages, the system designs the supply of water and nutrients to the crops at specific times and in appropriate proportions.

[0003] Integrated water and fertilizer irrigation systems are relatively mature irrigation systems on the market, with water-saving and high-efficiency functions. However, the water storage tanks of existing integrated water and fertilizer irrigation systems mostly use manual water filling. The water storage tanks are exposed to the air and are affected by external sunlight and hot air, which easily leads to the evaporation of water inside the water storage tanks. At the same time, a large amount of pollutants will enter the water storage tanks. For example, leaves, fruit peels and other garbage may be blown into the water storage tanks by the wind. Due to the lack of automatic cleaning and separation devices, the water inside the water storage tanks becomes smelly. More filtration steps are required later to make the water quality meet the irrigation requirements, resulting in unsatisfactory use effect. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a cleaning and separation system for an integrated water and fertilizer surface irrigation system, which has the following beneficial effects:

[0020] 1. The cleaning and separation system of this integrated water and fertilizer ground irrigation system allows the extension plate to be moved out of the water storage tank during rainy weather by activating the drive mechanism. The design of the extension plate can effectively increase the water receiving area of ​​the water storage tank, reduce the amount of additional water for irrigation, and make it more energy-efficient. The top plate design can cover the top of the water storage tank, and the lifting baffle can block the water inlet, reducing the contact between the water storage tank and air and light, and reducing the loss of water inside the water storage tank.

[0021] 2. The cleaning and separation system of this integrated water and fertilizer ground irrigation system, when the extension plate is moved out of the inside of the water storage tank, the extension plate drives the movable rod to move synchronously through the linkage mechanism, so that the movable rod drives the main brush at the bottom of the movable plate and the fixed plate to clean the top of the top plate, avoiding the accumulation of garbage on the top of the top plate, and also preventing garbage from entering the inside of the water storage tank through the water inlet, reducing the subsequent filtration steps, and making it more energy-saving and environmentally friendly.

[0022] 3. The cleaning and separation system of this integrated water and fertilizer ground irrigation system features specially designed stepped concave and convex platforms. When the drive head moves up or down inside the drive groove, it causes the movable plate to vibrate up and down and move back and forth multiple times. This allows the main brush at the bottom of the movable plate to perform high-frequency vibration cleaning on the top of the top plate, removing stubborn pollutants and greatly improving the cleaning effect.

[0023] 4. The cleaning and separation system of this integrated water and fertilizer ground irrigation system, through the automatic lifting design of the coarse filter and stainless steel filter, can automatically clean the inside of the extension plate when the extension plate is stored. At the same time, when the stainless steel filter is stored, the auxiliary brush can also clean the stainless steel filter, making it more convenient to use.

[0024] 5. The cleaning and separation system of this integrated water and fertilizer surface irrigation system has a drive mechanism that drives the extension plate to move. When the extension plate moves, it automatically triggers the linkage mechanism to drive the cleaning mechanism. At the same time, the extension plate automatically drives the baffle to disengage from the inside of the water inlet. The structure is ingeniously designed and only requires one drive source, making it more energy-efficient and environmentally friendly, and meeting the design requirements of the integrated water and fertilizer surface irrigation system.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-13 A cleaning and separation system for an integrated water and fertilizer surface irrigation system includes an integrated water and fertilizer irrigation device 1.

[0041] A drive mechanism 21 is provided on one side of the water storage tank 2. An extension plate 22 is provided inside the water storage tank 2. A movable hole 23 and a movable hole 29 located below the movable hole 23 are provided on one side of the water storage tank 2. One end of the extension plate 22 extends into the interior of the movable hole 29, and sliding shafts 221 are provided on the top of both sides of the other end. A top plate 24 is provided on the top of the water storage tank 2. Several water inlet holes 241 are provided inside the top plate 24. A drive groove 243 is provided on the top of both sides of the top plate 24. The drive mechanism 21 is used to drive the extension plate 22 to move out or into the interior of the water storage tank 2. Toothed grooves 222 are provided on both sides of the extension plate 22.

[0042] A cleaning mechanism 25 is provided on the top of the water storage tank 2. The cleaning mechanism 25 includes a movable rod 251 movably disposed inside the movable hole 23. One end of the movable rod 251 extends to the outside of the movable hole 23 and is provided with at least two support rods 252. The end of the support rod 252 away from the movable rod 251 extends to the top of the top plate 24 and is provided with at least two fixed plates 254. A movable plate 253 is movably disposed between the two fixed plates 254. A groove 254 is provided on the side of the fixed plate 254 facing the movable plate 253. 1. Several buffer rods 257 are fixedly installed on both sides of the movable plate 253. The end of the buffer rod 257 away from the movable plate 253 extends into the interior of the slide groove 2541 and is provided with a slider 258. The slider 258 is provided with springs located on both sides of one end of the buffer rod 257. A spring is provided at the top of the inner wall of the slide groove 2541. A main brush 255 is provided at the bottom of both the fixed plate 254 and the movable plate 253. A drive head 256 matching the drive groove 243 is provided at the bottom of both ends of the movable plate 253.

[0043] Both sides of the inner wall of the water storage tank 2 are provided with limiting grooves 26, and the two limiting grooves 26 are respectively located on both sides of the extension plate 22. A lifting plate 261 is movably arranged inside the limiting groove 26. A slide 262 is provided inside the lifting plate 261. The end of the slide 262 near the second movable hole 29 is bent upward to form an inclined track 265. One end of the sliding shaft 221 extends into the interior of the slide groove 2541. A transmission cavity 266 is provided at the end of the limiting groove 26 near the second movable hole 29. A linkage mechanism 28 is jointly provided inside the limiting groove 26 and the transmission cavity 266.

[0044] The water storage tank 2 is equipped with a mesh frame 27, which is located above the extension plate 22. Both ends of the mesh frame 27 are fixedly connected to two lifting plates 261. The top of the mesh frame 27 is equipped with baffles 271, which are the same number as the water inlet holes 241 and are one-to-one opposite each other. The top of the baffles 271 extends into the interior of the water inlet holes 241.

[0045] The linkage mechanism 28 includes a large gear 281, a small gear 282, and a secondary lead screw 283. One end of the small gear 282 extends into the interior of the tooth groove 222. The small gear 282, the large gear 281, and the secondary lead screw 283 are connected to each other for transmission. A nut seat 284 with one side connected to one end of the movable rod 251 is threaded on the secondary lead screw 283.

[0046] As a specific technical solution in this embodiment, the bottom of the inner wall of the drive groove 243 is arc-shaped, and several stepped recesses 2431 are provided on both sides of the inner wall of the drive groove 243. The top of the stepped recesses 2431 is inclined, and two adjacent stepped recesses 2431 are connected by inclined surfaces. The bottom of the drive head 256 is arc-shaped, and several stepped protrusions 2561 are provided on both sides of the bottom of the drive head 256. The bottom of the stepped protrusions 2561 is semi-circular, and two adjacent stepped protrusions 2561 are staggered by the height and width of one stepped protrusion 2561.

[0047] In this implementation plan, please refer to Figure 6-7The spring at the top of the inner wall of the slide 2541 continuously abuts against the uppermost slider 258. When the drive head 256 slides at the bottom of the top plate 24, the spring abuts against the slider 258, causing it to descend. The slider 258, through the buffer rod 257, drives the movable plate 253 to descend. This design allows the driven head 256 to quickly descend into the drive groove 243 when it is facing the drive groove 243. When the auxiliary lead screw 283 rotates, it drives the nut seat 284 to move along its axial direction. The nut seat 284, through the movable rod 251, drives the support rod 252 to move. The movable plate 253 and the fixed plate 254 move together, and the main brushes 255 at the bottom of the movable plate 253 and the fixed plate 254 clean the top of the top plate 24. At the same time, the drive head 256 at the bottom of the movable plate 253 moves and inserts into the drive groove 243. When the drive head 256 enters the drive groove 243, multiple stepped protrusions 2561 on one side of the bottom of the drive head 256 contact multiple stepped recesses 2431 on one side of the inner wall of the drive groove 243 in sequence. Due to the pressure of the spring, the multiple stepped protrusions 2561 on one side of the bottom of the drive head 256 contact the groove. When 561 contacts the multiple stepped recesses 2431 on one side of the inner wall of the drive groove 243 in sequence, it will produce a rapid, step-by-step descent effect, pausing briefly with each descent. As the movable rod 251 moves, after the drive head 256 is fully inside the drive groove 243, the stepped boss 2561 on the other side of the bottom of the drive head 256 and the stepped recesses 2431 on the other side of the inner wall of the drive groove 243 begin to contact, and are connected to adjacent stepped recesses 2431 through inclined planes, causing the stepped boss 2561 to rise step by step along the inclined planes. As the movable rod 251 moves, it causes... The multiple stepped protrusions 2561 on one side of the bottom of the drive head 256 pause briefly each time it rises. This design causes the drive head 256 to move up and down inside the drive groove 243, which in turn causes the movable plate 253 to vibrate up and down. This causes the main brush 255 at the bottom of the movable plate 253 to perform high-frequency vibration cleaning on the top of the top plate 24, removing stubborn contaminants and greatly improving the cleaning effect. Together with the main brush 255 at the bottom of the fixed plate 254, the contaminants on the top of the top plate 24 can be swept to one side of the top plate 24 and pushed away, eliminating the need for manual cleaning.

[0048] Furthermore, because the top of the uppermost slider 258 is pressurized by a spring, the speed at which the drive head 256 rises from inside the drive groove 243 is slower than the speed at which it descends. Since the movable rod 251 moves forward at a constant speed, this results in a speed difference between the upward speed of the drive head 256 from inside the drive groove 243 and the horizontal movement speed of the support rod 252 and the movable rod 251. At this time, the movable plate 253 is pressed and moves laterally towards one of the fixed plates 254. The buffer rods 257 on both sides of the movable plate 253 move along with the movable plate 253. The lateral movement of the sliding block 258 compresses the spring inside the slider 258. When the drive head 256 rises from the inside of the drive groove 243, the movable plate 253 is released from the lateral pressure. The spring inside the slider 258 rebounds and contacts the buffer rod 257 to quickly reset, so that the movable plate 253 quickly resets to the middle position of the two fixed plates 254. During the reset process of the movable block, it will drive the main brush 255 at its bottom to perform a quick sweeping action on the top of the top plate 24, further ensuring the cleaning effect of the main brush 255 on the stubborn pollutants on the top of the top plate 24.

[0049] As a specific technical solution of this embodiment, it also includes a conveyor belt 231. One side of the conveyor belt 231 is slidably fitted inside the movable hole 23, and the other side is slidably attached to one side wall of the water storage tank 2. The part of the movable rod 251 that passes through the movable hole 23 is sleeved inside the conveyor belt. An end cap 259 is provided between the fixed plate 254 and the support rod 252. The length of the movable plate 253 is less than the length of the fixed plate 254. A sealing sleeve 2531 is fitted around the top and bottom of the movable plate 253. Both ends of the fixed plate 254 have end caps 259. The end caps 259 and the support rod 252 can be connected by screws, which facilitates the disassembly of the end caps 259, the movable plate 253 and the fixed plate 254 together in the later stage, which facilitates the later maintenance.

[0050] In this embodiment, the sealing sleeves 2531 at the top and bottom of the movable plate 253 are made of rubber, which will not affect the up-down and back-down movement of the movable plate 253. The outer ring of the sealing sleeve 2531 is fixedly connected to the fixed plate 254 and the end cover 259, ensuring the sealing of the slide groove 2541. The front and rear sides of the inner wall of the slide groove 2541 are also provided with grooves. The front and rear sides of the slider 258 are provided with protrusions that slide and engage with the inside of the grooves, so that the slider 258 can only slide up and down in the slide groove 2541 and cannot move back and forth, thus ensuring the stability of the slider 258. The function of the conveyor belt 231 is mainly to block the movable hole 23, preventing debris from entering the movable hole 23 and the interior of the transmission cavity 266. At the same time, it will not affect the movement of the movable rod 251. When the movable rod 251 moves with the nut seat 284, the movable rod 251 drives the conveyor belt 231 to rotate, so that the conveyor belt 231 always blocks the movable hole 23.

[0051] As a specific technical solution of this embodiment, the bottom of the lifting plate 261 is provided with a plurality of stabilizing rods 263, the bottom of the inner wall of the limiting groove 26 is provided with stabilizing grooves 264, which are the same number as the stabilizing rods 263 and correspond one-to-one, and a plurality of ball bearings are movably embedded in the inner wall of the stabilizing groove 264. The bottom end of the stabilizing rod 263 extends into the interior of the stabilizing groove 264 and the surface of the stabilizing rod 263 slides in contact with the ball bearings. The bottom of the water inlet hole 241 is conical, and the top of the baffle 271 is provided with a sealing gasket 272.

[0052] In this embodiment, the ball bearings inside the stabilizing groove 264 make the lifting and lowering process of the stabilizing rod 263 smoother. The bottom of the water inlet hole 241 is conical, which makes it easier for the baffle rod 271 to descend and detach from the obstruction of the water inlet hole 241, and to re-insert into the water inlet hole 241. The sealing gasket 272 at the top of the baffle rod 271 ensures the sealing effect of the baffle rod 271 on the water inlet hole 241. When the baffle rod 271 descends, the gap between the sealing gasket 272 at the top of the baffle rod 271 and the water inlet hole 241 is only enough for rainwater to flow, preventing garbage such as fruit peels, paper peels, and leaves from entering the top of the water storage tank 2. If garbage such as fruit peels, paper peels, and leaves enter the water inlet hole 241, when the baffle rod 271 rises again, it will push the garbage inside the water inlet hole 241 back to the top of the top plate 24 and finally be swept away.

[0053] As a specific technical solution of this embodiment, the large gear 281 is rotatably disposed inside the transmission cavity 266. A small gear 282 is provided on one side of the large gear 281, inside the limiting groove 26, and at the end of the auxiliary lead screw 283. The small gear 282 located inside the limiting groove 26 meshes with the tooth groove 222. The small gear 282 located inside the limiting groove 26 and the small gear 282 on one side of the large gear 281 are connected by a toothed belt drive. The large gear 281 and the small gear 282 at the end of the auxiliary lead screw 283 are connected by a toothed belt drive.

[0054] In this embodiment, the number of extension plates 22 inside the water storage tank 2 is two, and the two extension plates 22 are arranged symmetrically. (See reference...) Figure 8Two limiting grooves 26 are provided on both sides of the inner wall of the water storage tank 2. The four limiting grooves 26 are paired and correspond to the two extension plates 22 respectively. Since the stroke of the extension plate 22 moving out of the water storage tank 2 is less than the stroke of the movable plate 253 driving the main brush 255 to move from one side of the top plate 24 to the other side, the large gear 281 is used for speed change. When the tooth groove 222 drives the small gear 282 to rotate one revolution, the small gear 282 drives the large gear 281 to rotate one revolution. The number of teeth of the large gear 281 is greater than that of the small gear 282. When the large gear 281 rotates one revolution, the large gear 281 drives the auxiliary lead screw 28. The small gear 282 at one end of the extension plate 22 rotates multiple times. This design allows the small gear 282 to mesh with the tooth groove 222 when the extension plate 22 moves. One rotation of the small gear 282 will drive the auxiliary lead screw 283 to rotate multiple times. When the extension plate 22 moves out of the water tank 2 into place, the auxiliary lead screw 283 also drives the movable rod 251 to move from one end of the movable hole 23 to the other end through the nut seat 284. This allows the support rod 252 to drive the fixed plate 254 and the movable plate 253 to complete the cleaning of the top plate 24. The bottom of the inner wall of the tooth groove 222 is inclined, which makes it difficult for pollutants to accumulate inside the tooth groove 222.

[0055] As a specific technical solution of this embodiment, the auxiliary lead screw 283 is rotatably disposed inside the transmission cavity 266 and located on one side of the movable hole 23. The transmission cavity 266 is also fixedly disposed inside a limiting rod 285 located on one side of the auxiliary lead screw 283 and a partition plate 267 located below the limiting rod 285 and the auxiliary lead screw 283. The surface of the limiting rod 285 is slidably sleeved with the inside of the nut seat 284. The top and one end of the nut seat 284 are movably embedded with at least one ball bearing.

[0056] In this embodiment, the toothed belt passes through the partition 267, which is used to separate the transmission cavity 266, further preventing contaminants from entering the interior of the transmission cavity 266 through the movable hole 23. The setting of the limiting rod 285 further ensures the stability of the nut seat 284, so that the nut seat 284 can only move axially along the auxiliary lead screw 283. The setting of the ball bearings allows the nut seat 284 to contact the inner wall of the transmission cavity 266 through the ball bearings, reducing sliding resistance.

[0057] As a specific technical solution of this embodiment, the driving mechanism 21 includes a motor housing 211 with a drive motor installed inside. A transmission box 212 is provided at the bottom of the motor housing 211. A main lead screw 213 is provided inside the transmission box 212. The two ends of the main lead screw 213 extend to the two sides of the water storage tank 2 respectively, and the threads of the two ends of the main lead screw 213 are opposite. Both ends of the main lead screw 213 are connected to a transmission rod 215 through a nut sleeve. The transmission rod 215 is located below the main lead screw 213. A connecting rod 216 is provided at the end of the transmission rod 215 away from the nut sleeve. The end of the connecting rod 216 away from the transmission rod 215 is fixedly connected to one side of the extension plate 22. Protective plates 214 are fixedly provided on both sides of the motor housing 211. The protective plates 214 are located above the main lead screw 213.

[0058] In this embodiment, the two transmission rods 215 on the main lead screw 213 are used to drive the two extension plates 22 respectively, and the threads at both ends of the main lead screw 213 are opposite, so that when the main lead screw 213 is driven to rotate by the motor, the transmission rods 215 at both ends of the main lead screw 213 move relative to each other or move in opposite directions. There are two drive mechanisms 21, which are respectively set on both sides of the water storage tank 2, and the two motors are controlled by the controller to rotate synchronously. This design means that both ends of one side of the extension plate 22 are provided with connecting rods 216, so that when the extension plate 22 is moved out and put back, the force is more even and the jamming is avoided. The protective plate 214 protects the main lead screw 213.

[0059] As a specific technical solution of this embodiment, a receiving cavity 291 is provided at the top of the inner wall of the second movable hole 29. A coarse filter 292 and a stainless steel filter 293 located on one side of the coarse filter 292 are arranged inside the receiving cavity 291 by a spring. A secondary brush 294 is provided at the bottom of one side of the inner wall of the receiving cavity 291. One side of the secondary brush 294 is in contact with one side of the stainless steel filter 293. A pushing inclined surface 223 is provided on one side of the inner wall of the extension plate 22.

[0060] In this embodiment, the coarse filter screen 292 is made of a relatively soft material. To prevent the coarse filter screen 292 from deforming due to the pressure from its top spring, a stainless steel filter screen 293 is installed on one side of the coarse filter screen 292. The stainless steel filter screen 293 is made of a hard material and can effectively protect the coarse filter screen 292 from deformation. The top plate 24 is fixed to the top of the water storage tank 2 with screws. When backwashing the coarse filter screen 292 and the stainless steel filter screen 293 is required, the top plate 24 can be removed for rinsing. During the removal or retraction of the extension plate 22, the support rod 252 simultaneously drives the main brush 255 to clean the top of the top plate 24. When the extension plate 22 is fully retracted, the coarse filter screen 292 and the stainless steel filter screen 293 compress the springs at their tops and are completely submerged inside the storage cavity 291. When the drive mechanism 21 is activated to move the extension plate 22 out, one end of the top of the extension plate 22 is removed from obstructing the coarse filter screen 292 and the stainless steel filter screen 293. At the same time, as the extension plate 22 moves... The coarse filter screen 292 and the stainless steel filter screen 293 descend along the pusher slope 223 into the interior of the extension plate 22. In rainy weather, rainwater entering the interior of the extension plate 22 is filtered by the stainless steel filter screen 293 and the coarse filter screen 292 and then flows into the interior of the water storage tank 2. When the drive mechanism 21 is activated to move the extension plate 22 into the interior of the water storage tank 2, the stainless steel filter screen 293 intercepts the pollutants inside the extension plate 22 and pushes them out when it passes through the pusher slope 223. At the same time, the pusher slope 223 abuts against the stainless steel filter screen 293, which will cause the stainless steel filter screen 293 and the coarse filter screen 292 to rise. The auxiliary brush 294 can clean the stainless steel filter screen 293 during the rising process without manual operation, making it more convenient to use. The structure is cleverly designed. By driving the extension plate 22 to move through the drive mechanism 21, the cleaning of the top plate 24 and the extension plate 22 as well as the cleaning of the stainless steel filter screen can be completed simultaneously, making it more convenient and energy-saving to use.

[0061] As a specific technical solution of this embodiment, both ends of the top plate 24 are provided with guide slopes 242, one of which is located between two movable plates 253. Both sides of the inner wall of the water storage tank 2 are provided with support bars 201, and the two support bars 201 are respectively located at the bottom of the two sides of the extension plate 22. A filter plate 202 is also movably arranged inside the water storage tank 2. One end of the filter plate 202 extends to one side of the water storage tank 2. The filter plate 202 is located below the extension plate 22. Both sides of the inner wall of the water storage tank 2 are fixedly provided with support bars 203 whose tops are movably connected to the bottoms of the filter plate 202. The support bars 201 and 203 are relatively narrow and are mainly used to support the extension plate 22 and the filter plate 202.

[0062] In this implementation plan, please refer to Figure 2-4There are four support rods 252 on the two movable rods 251. The four support rods 252 are opposite each other. When the movable rods 251 move to either end of the movable hole, there are always two opposite support rods 252 that extend beyond the top of the top plate 24. This design allows the contaminants on the top of the top plate 24 to be effectively swept off the top plate 24 when cleaning the top plate 24. The contaminants between the two movable plates 253 will automatically slide off due to the slope of the guide ramp 242, further improving the cleaning effect. The filter plate 202 is used to filter the water entering through the water inlet 241. The filter plate 202 can be cleaned by pulling it out from one side of the water tank 2.

[0063] In use, on rainy days, the drive mechanism 21 is activated. The drive mechanism 21 moves the extension plate 22 out of the water storage tank 2. When the extension plate 22 moves, it drives the sliding shaft 221 to move inside the slide rail 262. Because the inclined rail 265 is close to the second movable hole 29, the extension plate 22 does not drive the lifting plate 261 to descend when it first starts to move, so the stop rod 271 continues to block the water inlet hole 241. However, when the extension plate 22 first starts to move, it will drive the pinion 282 to rotate. The pinion 282 drives the auxiliary lead screw 283 to rotate through the large gear 281. The auxiliary lead screw 283 drives the nut seat 284 and the movable rod 251 to move. The movable rod 251, through the support rod 252, drives the main brush 255 at the bottom of the fixed plate 254 and the movable plate 253 to clean the top plate 24. As the movable plate 253 moves, the drive head 256 at the bottom inserts into the drive groove 243. When the drive head 256 enters the drive groove 243, multiple stepped protrusions 2561 on one side of the bottom of the drive head 256 contact multiple stepped recesses 2431 on one side of the inner wall of the drive groove 243 in sequence. When the spring pressure causes the multiple stepped protrusions 2561 on one side of the bottom of the drive head 256 to contact the multiple stepped recesses 2431 on one side of the inner wall of the drive groove 243 in sequence, a rapid, step-by-step descent effect occurs, with a brief pause at each descent. As the movable rod 251 moves, and the drive head 256 is fully inserted into the drive groove 243, the stepped protrusions 2561 on the other side of the bottom of the drive head 256 and the stepped recesses 2431 on the other side of the inner wall of the drive groove 243 begin to contact, and also contact two adjacent stepped recesses 2431. 431 is connected by a ramp, which allows the stepped protrusions 2561 to rise step by step along the ramp. As the movable rod 251 moves, the multiple stepped protrusions 2561 on the bottom side of the drive head 256 will pause each time they rise. This design means that when the drive head 256 moves up or down inside the drive groove 243, it will drive the movable plate 253 to vibrate up and down. This causes the main brush 255 at the bottom of the movable plate 253 to perform high-frequency vibration cleaning on the top of the top plate 24, removing stubborn pollutants and greatly improving the cleaning effect.

[0064] When the extension plate 22 is almost completely removed, the sliding shaft 221 slides into the interior of the inclined chute 265. Due to the design of the inclined chute 265, the sliding shaft 221 slides into the interior of the inclined chute 265, causing the lifting plate 261 to descend. When the lifting plate 261 descends, it drives the baffle 271 to disengage from the interior of the water inlet 241 through the mesh frame 27, allowing rainwater to enter the interior of the water storage tank 2 through the water inlet 241. At the same time, the extension plate 22 is also completely removed, so that the interior of the water storage tank 2 can collect rainwater during rainy days and filter the rainwater, reducing the need for subsequent filtration steps and making it more convenient to use. After the rainy day ends, the drive is activated. Mechanism 21 drives the two extension plates 22 to retract into the water storage tank 2 simultaneously. At the same time, the auxiliary lead screw 283 reverses and drives the nut seat 284 to move. The nut seat 284 drives the movable plate 253 and the fixed plate 254 to clean the top of the top plate 24 again. When the extension plate 22 is initially retracted, the sliding shaft 221 disengages from the inclined rail 265 and enters the sliding rail 262, which causes the lifting plate 261 to rise. The lifting plate 261 drives the baffle 271 to block the water inlet hole 241, preventing contaminants on the top of the top plate 24 from entering the water storage tank 2 through the water inlet hole 241 when cleaning the top plate 24.

[0065] In summary, the cleaning and separation system of this integrated water and fertilizer ground irrigation system allows the extension plate 22 to be moved out of the water storage tank 2 during rainy weather by activating the drive mechanism 21. The design of the extension plate 22 can effectively increase the water receiving area of ​​the water storage tank 2, reduce the amount of additional water for irrigation, and make it more energy-efficient.

[0066] In this integrated water and fertilizer ground irrigation system, when the extension plate 22 is moved out of the water storage tank 2, the extension plate 22 drives the movable rod 251 to move synchronously through the linkage mechanism 28. This causes the movable rod 251 to drive the main brush 255 at the bottom of the movable plate 253 and the fixed plate 254 to clean the top of the top plate 24. This prevents garbage from accumulating on the top of the top plate 24 and also prevents garbage from entering the water storage tank 2 through the water inlet 241, reducing the need for subsequent filtration steps and making the system more energy-efficient and environmentally friendly.

[0067] The cleaning and separation system of this integrated water and fertilizer ground irrigation system features a specially designed stepped concave platform 2431 and stepped convex platform 2561. When the drive head 256 moves up or down inside the drive groove 243, it drives the movable plate 253 to vibrate up and down and move back and forth multiple times. This causes the main brush 255 at the bottom of the movable plate 253 to perform high-frequency vibration cleaning on the top of the top plate 24, removing stubborn pollutants and greatly improving the cleaning effect.

[0068] The cleaning and separation system of this integrated water and fertilizer surface irrigation system, through the automatically lifting design of the coarse filter 292 and the stainless steel filter 293, can automatically clean the inside of the extension plate 22 when it is stored. At the same time, when the stainless steel filter 293 is stored, the auxiliary brush 294 can also clean the stainless steel filter 293, making it more convenient to use.

[0069] The cleaning and separation system of this integrated water and fertilizer ground irrigation system has a drive mechanism 21 that drives the extension plate 22 to move. When the extension plate 22 automatically triggers the linkage mechanism 28 to drive the sweeping mechanism 25 to run, the extension plate 22 also automatically drives the baffle 271 to disengage from the water inlet hole 241. The structure is ingeniously designed and only requires one drive source, the drive mechanism 21. It is more energy-efficient and environmentally friendly, and meets the design requirements of the integrated water and fertilizer ground irrigation system.
