Description

Technical Field

[0001] The invention relates to the technical field of cleaning and separation, and in particular to a cleaning and separation system for a water-fertilizer integrated ground irrigation system. Background Art

[0002] Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. Integrated water and fertilizer technology uses a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types. The fertilizer solution is mixed with irrigation water and supplied through a controllable pipeline system. After the water and fertilizer are mixed, sprinkler irrigation or drip irrigation is formed through pipelines and drippers to evenly, regularly and quantitatively infiltrate the root development and growth area of ​​the crop, so that the main root soil always maintains looseness and appropriate water content; at the same time, according to the fertilizer requirements of different crops, soil environment and nutrient content, the water requirements of crops in different growth periods, and the fertilizer requirements, the demand design for different growth periods is carried out, and water and nutrients are provided to crops directly in a regular and quantitative manner in proportion.

[0003] The integrated water-fertilizer irrigation system is a relatively mature irrigation system on the market, with water-saving and high-efficiency functions. However, the water tanks of the existing integrated water-fertilizer irrigation systems are mostly stored by artificial water injection. The water tanks are retained under the air and are affected by external light and hot air, which can easily cause the water inside the water tank to evaporate. At the same time, a large amount of pollutants will enter the interior of the water tank. For example, garbage such as leaves, fruit peels, etc. may be blown into the interior of the water tank by the wind. Due to the lack of automatic cleaning and separation of debris, the water inside the water tank becomes smelly. In the later stage, more filtration steps need to be added to make the water quality meet the irrigation requirements, and the use effect is not ideal. Summary of the invention

The design of the extension plate can effectively increase the water receiving area of ​​the water reservoir, reduce the additional water injection irrigation volume, and use more energy-saving. Through the design of the top plate, the top of the water reservoir can be shielded, and the lifting barrier rod can block the water inlet, reducing the contact of the water reservoir with air and light, and reducing the loss of water inside the water reservoir.

[0016] 2. The cleaning and separation system of the water-fertilizer integrated ground irrigation system, when the extension plate is moved out from the interior of the water reservoir, the extension plate synchronously drives the movable rod to move 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 the entry of garbage into the interior of the water reservoir through the water inlet hole, reducing the later filtering steps, and being more energy-saving and environmentally friendly.

[0017] 3. The cleaning and separation system of the integrated water-fertilizer ground irrigation system has specially designed stepped concave and stepped convex platforms, so that when the driving head moves down or up inside the driving groove, it will drive the movable plate to vibrate up and down and move back and forth multiple times, so that the main brush at the bottom of the movable plate can vibrate and clean the top of the top plate at a high frequency, thereby removing stubborn pollutants and greatly improving the cleaning effect.

[0018] 4.

[0019] 5. The cleaning and separation system of the water-fertilizer integrated ground irrigation system, when the driving mechanism drives the extension plate to move, the extension plate automatically triggers the linkage mechanism to drive the cleaning mechanism to operate, and at the same time the extension plate automatically drives the baffle rod to separate from the inside of the water inlet hole.

The bottom of both ends of the movable plate 253 are both provided with driving heads 256 matching the driving groove 243.

[0026] Limiting grooves 26 are provided on both sides of the inner wall of the water reservoir 2, and the two limiting grooves 26 are respectively located on both sides of the extension plate 22, and a lifting plate 261 is movably provided inside the limiting groove 26, and a slide 262 is provided inside the lifting plate 261, and the end of the slide 262 close to the movable hole 29 is bent upward to form a ramp 265, and one end of the sliding shaft 221 extends to the inside of the slide groove 2541, and a transmission cavity 266 is provided at the end of the limiting groove 26 close to the movable hole 29, and a linkage mechanism 28 is provided inside the limiting groove 26 and the transmission cavity 266.

[0027] A grid 27 is provided inside the water reservoir 2, and the grid 27 is located above the extension plate 22. The two ends of the grid 27 are fixedly connected to two lifting plates 261. The top of the grid 27 is provided with blocking rods 271 whose number is the same as and opposite to the water inlet holes 241, and the top of the blocking rod 271 extends to the inside of the water inlet hole 241.

[0028] The linkage mechanism 28 includes a large gear 281, a small gear 282 and a secondary screw rod 283. One end of the small gear 282 extends to the inside of the tooth groove 222. The small gear 282, the large gear 281 and the secondary screw rod 283 are connected to each other in a transmission manner. A nut seat 284 is threadedly sleeved on the secondary screw rod 283, one side of which is connected to one end of the movable rod 251.

[0029] As a specific technical solution of this embodiment, the bottom of the inner wall of the driving groove 243 is in an arc shape, and a plurality of stepped recesses 2431 are arranged on both sides of the inner wall of the driving groove 243. The top of the stepped recess 2431 is an inclined surface, and two adjacent stepped recesses 2431 are connected by the inclined surface. The bottom end of the driving head 256 is in an arc shape, and a plurality of stepped bosses 2561 are arranged on both sides of the bottom of the driving head 256. The bottom end of the stepped boss 2561 is semicircular, and two adjacent stepped bosses 2561 are staggered from each other by a distance equal to the height and width of a stepped boss 2561.

[0030] In this implementation plan, refer to Figure 6-7The spring at the top of the inner wall of the slide groove 2541 continuously resists the uppermost slider 258. When the driving head 256 slides at the bottom of the top plate 24, the spring resists the slider 258 to move down, and the slider 258 drives the movable plate 253 to move down through the buffer rod 257. This design method allows the driving head 256 to be pressed and quickly drop into the driving groove 243 when it is opposite to the driving groove 243. When the auxiliary screw rod 283 rotates, it drives the nut seat 284 to move along its axial direction. The nut seat 284 drives the support rod 252 to move through the movable rod 251. The support rod 252 The movable plate 253 and the fixed plate 254 are driven to move, 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 driving head 256 at the bottom of the movable plate 253 is inserted into the driving groove 243 as it moves. When the driving head 256 enters the driving groove 243, the multiple stepped bosses 2561 at the bottom of one side of the driving head 256 contact the multiple stepped recesses 2431 on the inner wall of one side of the driving groove 243 in sequence. Since the driving head 256 is resisted by the pressure of the spring, the multiple stepped bosses 2561 at the bottom of one side of the driving head 256 contact the multiple stepped recesses 2431 on the inner wall of one side of the driving groove 243. When the movable rod 251 contacts with the multiple stepped recesses 2431 on the inner wall of one side of the driving groove 243 in sequence, a step-by-step rapid descent effect will be produced, and each descent will pause. As the movable rod 251 moves, the driving head 256 completely enters the driving groove 243, and the stepped boss 2561 at the bottom of the other side of the driving head 256 begins to contact the stepped recess 2431 on the other side of the inner wall of the driving groove 243, and is connected with two adjacent stepped recesses 2431 through an inclined plane, so that the stepped boss 2561 rises step by step along the inclined plane, and as the movable rod 251 moves, the stepped boss 2561 The multiple stepped bosses 2561 at the bottom of one side of the driving head 256 will pause each time they rise. This design method allows the driving head 256 to drive the movable plate 253 to vibrate up and down when it moves downward or upward inside the driving groove 243, so that the main brush 255 at the bottom of the movable plate 253 performs high-frequency vibration cleaning on the top of the top plate 24 to remove stubborn pollutants, greatly improving the cleaning effect. The main brush 255 at the bottom of the fixed plate 254 can clean the pollutants on the top of the top plate 24 to one side of the top plate 24 and push them away without manual cleaning. Since there is a spring pressure on the top of the uppermost slider 258, the speed at which the driving head 256 rises from the driving groove 243 is slower than the speed at which the driving head 256 descends, and the movable rod 251 moves at a uniform speed, which results in a speed difference between the speed at which the driving head 256 rises from the driving groove 243 and the speed at which the support rod 252 and the movable rod 251 move horizontally. At this time, the movable plate 253 is pressed to move sideways, and the movable plate 253 moves toward one of the fixed plates 254. The buffer rods 257 on both sides of the movable plate 253 move with the movable plate 253. The lateral movement of the slider 258 resists the compression of 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 freed from the lateral pressure, and the spring inside the slider 258 rebounds and resists the buffer rod 257 to quickly reset, so that the movable plate 253 is quickly reset to the middle position between the two fixed plates 254. In the process of resetting the movable block, the main brush 255 at the bottom thereof will be driven to quickly sweep 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.

[0031] As a specific technical solution of this embodiment, it also includes a conveyor belt 231, one side of which is slidably sleeved inside the movable hole 23, and the other side is slidably fitted with a side wall of the water reservoir 2, the movable rod 251 passes through the movable hole 23 and is sleeved with the inside of the transmission belt, an end cover 259 is arranged 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, the top circle and the bottom circle of the movable plate 253 are both sleeved with sealing sleeves 2531, both ends of the fixed plate 254 are provided with end covers 259, the end covers 259 and the support rod 252 can be connected by screws, which is convenient for later disassembly together with the end covers 259, the movable plate 253 and the fixed plate 254, and convenient for later maintenance.

[0032] In this embodiment, the sealing sleeve 2531 at the top and bottom of the movable plate 253 is made of rubber material, which will not affect the up and down, front and back movements 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, and the front and rear sides of the slider 258 are provided with protrusions that are slidably sleeved with the inside of the groove, so that the slider 258 can only slide up and down in the slide groove 2541, and cannot move forward and backward, thereby ensuring the stability of the slider 258. The function of the conveyor belt 231 is mainly to block the movable hole 23 to prevent debris from entering the movable hole 23 and 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 simultaneously drives the conveyor belt 231 to rotate, so that the conveyor belt 231 always blocks the movable hole 23.

[0033] As a specific technical solution of this embodiment, a plurality of stabilizing rods 263 are arranged at the bottom of the lifting plate 261, and a plurality of stabilizing grooves 264 which are the same in number and correspond one to one with the stabilizing rods 263 are arranged at the bottom of the inner wall of the limiting groove 26, and a plurality of balls are movably embedded on the inner wall of the stabilizing groove 264, and the bottom end of the stabilizing rod 263 extends to the interior of the stabilizing groove 264 and the surface of the stabilizing rod 263 is in sliding contact with the balls, the bottom of the water inlet hole 241 is conical, and a sealing gasket 272 is arranged on the top of the blocking rod 271.

[0034] In this embodiment, the ball bearings inside the stabilizing groove 264 make the lifting and lowering process of the stabilizing rod 263 smoother, and the bottom of the water inlet hole 241 is tapered, so that the blocking rod 271 can be lowered to break away from the obstruction of the water inlet hole 241 and can be inserted into the water inlet hole 241 again more smoothly. The sealing gasket 272 on the top of the blocking rod 271 ensures the sealing effect of the blocking rod 271 on the water inlet hole 241, and when the blocking rod 271 is lowered, the gap between the sealing gasket 272 on the top of the blocking rod 271 and the water inlet hole 241 is just enough for rainwater to flow, thereby preventing garbage such as fruit peels and leaves from entering the top of the water reservoir 2. If garbage such as fruit peels and leaves enter the inside of the water inlet hole 241, when the blocking rod 271 rises again, the garbage inside the water inlet hole 241 will be pushed back to the top of the top plate 24 and finally swept away.

[0035] As a specific technical solution of this embodiment, the large gear 281 is rotatably arranged inside the transmission chamber 266, and small gears 282 are arranged on one side of the large gear 281, inside the limiting groove 26, and at the end of the auxiliary screw rod 283. The small gear 282 located inside the limiting groove 26 is meshed with the tooth groove 222, and 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 transmission, and the large gear 281 is connected to the small gear 282 at the end of the auxiliary screw rod 283 by a toothed belt transmission.

[0036] In this embodiment, the number of the extension plates 22 inside the water reservoir 2 is two, and the two extension plates 22 are symmetrically arranged. Figure 8Two limiting grooves 26 are provided on both sides of the inner wall of the water reservoir 2. The four limiting grooves 26 are opposite to each other and correspond to the two extension plates 22 respectively. Since the travel of the extension plate 22 moving out of the water reservoir 2 is less than the travel of the main brush 255 driven by the movable plate 253 to move from one side of the top plate 24 to the other side, the gear 281 is changed in speed so that when the tooth groove 222 drives the small gear 282 to rotate one circle, the small gear 282 drives the large gear 281 to rotate one circle. The number of teeth of the large gear 281 is greater than that of the small gear 282, so that when the large gear 281 rotates one circle, the large gear 281 drives the auxiliary screw rod 28 3, the pinion 282 at one end rotates multiple times. This design method allows the extension plate 22 to engage the transmission pinion 282 through the tooth groove 222 when it moves. One rotation of the pinion 282 will drive the auxiliary screw rod 283 to rotate multiple times. When the extension plate 22 is moved out of the water reservoir 2, the auxiliary screw rod 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, so that the support rod 252 drives 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 an inclined surface, which is not easy to hide pollutants inside the tooth groove 222.

[0037] As a specific technical solution of this embodiment, the auxiliary screw rod 283 is rotatably arranged inside the transmission chamber 266 and located on one side of the movable hole 23. The interior of the transmission chamber 266 is also fixedly provided with a limit rod 285 located on one side of the auxiliary screw rod 283 and a partition plate 267 located below the limit rod 285 and the auxiliary screw rod 283. The surface of the limit rod 285 is slidably sleeved with the interior of the nut seat 284, and the top and one end of the nut seat 284 are movably embedded with at least one ball.

[0038] In this embodiment, the toothed belt passes through the partition 267, and the partition 267 is used to separate the transmission chamber 266, further preventing contaminants from entering the interior of the transmission chamber 266 through the movable hole 23. The setting of the limit rod 285 further ensures the stability of the nut seat 284, so that the nut seat 284 can only move axially along the secondary screw 283. The setting of the ball makes the nut seat 284 contact with the inner wall of the transmission chamber 266 through the ball, thereby reducing sliding resistance.

[0039] As a specific technical solution of this embodiment, the driving mechanism 21 includes a motor box 211 with a driving motor installed inside, a transmission box 212 is arranged at the bottom of the motor box 211, and the internal transmission of the transmission box 212 is provided with a main screw 213, and the two ends of the main screw 213 extend to the two sides of the water reservoir 2 respectively, and the threads at the two ends of the main screw 213 have opposite directions; both ends of the main screw 213 are connected with a transmission rod 215 through a nut sleeve, and the transmission rod 215 is located below the main screw 213, and a connecting rod 216 is arranged at the end of the transmission rod 215 away from the nut sleeve, and the end of the connecting rod 216 away from the transmission rod 215 is fixedly connected to one side of the extension plate 22, and protective plates 214 are fixedly arranged on both sides of the motor box 211, and the protective plates 214 are located above the main screw 213.

[0040] In this embodiment, the two transmission rods 215 on the main screw 213 are respectively used to drive the two extension plates 22, and the threads at both ends of the main screw 213 have opposite directions, so that when the main screw 213 is driven to rotate by the motor, the transmission rods 215 at both ends of the main screw 213 perform relative movement or opposite movement. The number of the driving mechanisms 21 is two, which are respectively arranged on both sides of the water reservoir 2 and the two motors are controlled by the controller to rotate synchronously. This design method enables connecting rods 216 to be provided at both ends of one side of the extension plate 22, so that when the extension plate 22 is moved out and stored, the force is more uniform to avoid jamming, and the protective plate 214 protects the main screw 213.

[0041] As a specific technical solution of this embodiment, a storage chamber 291 is arranged at the top of the inner wall of the movable hole 29, and a coarse filter screen 292 and a stainless steel filter screen 293 located on one side of the coarse filter screen 292 are arranged inside the storage chamber 291 through a spring, and an auxiliary brush 294 is arranged at the bottom of one side of the inner wall of the storage chamber 291, and one side of the auxiliary brush 294 is in contact with one side of the stainless steel filter screen 293, and a pushing slope 223 is arranged on one side of the inner wall of the extension plate 22.

[0042] In the present embodiment, the coarse filter 292 is made of a relatively soft material. In order to prevent the coarse filter 292 from being deformed by the pressure of the spring on its top, a stainless steel filter 293 is arranged on one side of the coarse filter 292. The stainless steel filter 293 is made of a hard material and can effectively protect the coarse filter 292 from deformation. The top plate 24 is fixed to the top of the water reservoir 2 by screws. When the coarse filter 292 and the stainless steel filter 293 need to be backwashed, the top plate 24 can be disassembled to perform the flushing operation. During the removal or storage of the extension plate 22, the support rod 252 synchronously drives the main brush 255 to clean the top of the top plate 24. When the extension plate 22 is fully stored, the coarse filter 292 and the stainless steel filter 293 compress the spring on their top and are completely immersed in the storage chamber 291. When the driving mechanism 21 is started to drive the extension plate 22 to move out, the top end of the extension plate 22 is separated from the cover of the coarse filter 292 and the stainless steel filter 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 pushing inclined surface 223 to the inside of the extension plate 22. On rainy days, rainwater entering the extension plate 22 is filtered by the stainless steel filter screen 293 and the coarse filter screen 292 and flows into the water reservoir 2. When the driving mechanism 21 is started to drive the extension plate 22 to be stored in the water reservoir 2, the stainless steel filter screen 293 intercepts the pollutants inside the extension plate 22 and pushes the pollutants out when passing through the pushing inclined surface 223. At the same time, the pushing inclined surface 223 hits the stainless steel filter screen 293 and drives the stainless steel filter screen 293 and the coarse filter screen 292 to rise. The auxiliary brush 294 is set to clean the stainless steel filter screen 293 during the rising process. No manual operation is required, which is more convenient to use. The structural design is ingenious. The extension plate 22 is driven to move by the driving mechanism 21, so that the cleaning of the top plate 24 and the extension plate 22 and the cleaning of the stainless steel filter screen can be completed at the same time, which is more convenient to use and energy-saving.

[0043] As a specific technical solution of this embodiment, both ends of the top of the top plate 24 are provided with guide slopes 242, one of the guide slopes 242 is located between the two movable plates 253, support bars 201 are provided on both sides of the inner wall of the water reservoir 2, and the two support bars 201 are respectively located at the bottom of both sides of the extension plate 22, and a filter plate 202 is also movably arranged inside the water reservoir 2, one end of the filter plate 202 extends to one side of the water reservoir 2, and the filter plate 202 is located below the extension plate 22, and both sides of the inner wall of the water reservoir 2 are fixedly provided with support bars 203 movably connected to the top and the bottom of the filter plate 202, and the support bars 1 201 and 203 are narrow, and are mainly used to support the extension plate 22 and the filter plate 202.

[0044] In this implementation plan, refer to Figure 2-4There are four support rods 252 on the two movable rods 251, and the four support rods 252 are opposite to each other. When the movable rod 251 moves to any one end of the two ends of the movable hole, there are always two opposite support rods 252 exceeding the top of the top plate 24. This design makes it possible to effectively sweep the pollutants on the top of the top plate 24 off the top plate 24 when cleaning the top plate 24, and the pollutants between the two movable plates 253 automatically slide down due to the slope of the guide slope 242, and the cleaning effect is further improved. The filter plate 202 is used to filter the water entering the water inlet hole 241, and the filter plate 202 can be cleaned by pulling it out from one side of the water reservoir 2.

[0045] When in use, on rainy days, the driving mechanism 21 is started, and the driving mechanism 21 drives the extension plate 22 to move out of the water reservoir 2. When the extension plate 22 moves, it drives the sliding shaft 221 to move inside the slideway 262. Since the ramp 265 is close to the movable hole 29, when the extension plate 22 starts to move, it will not drive the lifting plate 261 to move down, so that the blocking rod 271 continues to block the water inlet hole 241. However, when the extension plate 22 starts to move, it will drive the small gear 282 to rotate, and the small gear 282 drives the auxiliary screw rod 283 to rotate through the large gear 281. The auxiliary screw rod 283 drives the nut seat 284 and the movable rod 251 to move, and the movable rod 251 drives the fixed plate 254 and the main brush 255 at the bottom of the movable plate 253 through the support rod 252 to clean the top plate 24, and the driving head 256 at the bottom of the movable plate 253 is inserted into the driving groove 243 as it moves. When the driving head 256 enters the driving groove 243, the multiple stepped bosses 2561 at the bottom of one side of the driving head 256 contact the multiple stepped recesses 2431 on the inner wall of one side of the driving groove 243 in sequence. The spring 256 is pressed against the drive head 256, so that the multiple stepped bosses 2561 at the bottom of one side of the drive head 256 contact the multiple stepped recesses 2431 on the inner wall of one side of the drive groove 243 in turn, which will produce a step-by-step rapid descent effect and pause each time it descends. As the movable rod 251 moves, the drive head 256 completely enters the drive groove 243, and the stepped bosses 2561 at the bottom of the other side of the drive head 256 begin to contact the stepped recesses 2431 on the other side of the inner wall of the drive groove 243, and contact the two adjacent stepped recesses 2431. 431 is connected by an inclined plane, so that the stepped boss 2561 rises step by step along the inclined plane, and as the movable rod 251 moves, the multiple stepped bosses 2561 at the bottom of one side of the driving head 256 will pause each time they rise. This design method makes the driving head 256 drive the movable plate 253 to vibrate up and down when it moves down or up inside the driving groove 243, so that the main brush 255 at the bottom of the movable plate 253 performs high-frequency vibration cleaning on the top of the top plate 24 to remove stubborn pollutants, and the cleaning effect is greatly improved; When the extension plate 22 is almost completely moved out, the sliding shaft 221 slides into the interior of the ramp 265. Due to the design of the ramp 265, the sliding shaft 221 slides into the interior of the ramp 265 and drives the lifting plate 261 to descend. When the lifting plate 261 descends, the blocking rod 271 is driven by the grid 27 to separate from the interior of the water inlet hole 241, so that rainwater enters the interior of the water reservoir 2 through the water inlet hole 241. At the same time, the extension plate 22 is also completely moved out, and the interior of the water reservoir 2 can be used to collect rainwater on rainy days and filter the rainwater, thereby reducing the later filtering steps and making it more convenient to use. After the rainy day is over, the drive is started. The mechanism 21 drives the two extension plates 22 to be synchronously retracted into the interior of the water tank 2, and at the same time, the auxiliary screw 283 reverses to drive the nut seat 284 to move, and 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 ramp 265 and enters the slide 262, which will cause the lifting plate 261 to rise, and the lifting plate 261 drives the blocking rod 271 to block the water inlet hole 241, thereby preventing pollutants on the top of the top plate 24 from entering the interior of the water tank 2 through the water inlet hole 241 when cleaning the top plate 24.

[0046] To sum up, in the cleaning and separation system of the water-fertilizer integrated ground irrigation system, when it rains, the driving mechanism 21 is started to drive the extension plate 22 to move out from the inside of the water reservoir 2. The design of the extension plate 22 can effectively increase the water receiving area of ​​the water reservoir 2, reduce the additional water injection irrigation amount, and use more energy-saving.

[0047] In the cleaning and separation system of the water-fertilizer integrated ground irrigation system, when the extension plate 22 is moved out from the interior of the water reservoir 2, the extension plate 22 synchronously drives the movable rod 251 to move through the linkage mechanism 28, so that the movable rod 251 drives the movable plate 253 and the main brush 255 at the bottom of the fixed plate 254 to clean the top of the top plate 24, thereby avoiding the accumulation of garbage on the top of the top plate 24 and avoiding the garbage from entering the interior of the water reservoir 2 through the water inlet hole 241, reducing the later filtering steps, and being more energy-saving and environmentally friendly.

[0048] The cleaning and separation system of the water-fertilizer integrated ground irrigation system has specially designed stepped recesses 2431 and stepped bosses 2561, so that when the driving head 256 moves downward or upward inside the driving groove 243, it will drive the movable plate 253 to vibrate up and down and move back and forth multiple times, so that the main brush 255 at the bottom of the movable plate 253 can vibrate and clean the top of the top plate 24 at a high frequency, thereby removing stubborn pollutants and greatly improving the cleaning effect.

[0049] The cleaning and separation system of the water-fertilizer integrated ground irrigation system can automatically clean the inside of the extension plate 22 when the extension plate 22 is stored through the coarse filter 292 and the stainless steel filter 293 with automatic lifting design. At the same time, when the stainless steel filter 293 is stored, the auxiliary brush 294 can also clean the stainless steel filter 293, which is more convenient to use.

[0050] In the cleaning and separation system of the water-fertilizer integrated ground irrigation system, when the driving mechanism 21 drives the extension plate 22 to move, the extension plate 22 automatically triggers the linkage mechanism 28 to drive the cleaning mechanism 25 to operate, and at the same time, the extension plate 22 automatically drives the blocking rod 271 to separate from the inside of the water inlet hole 241. The structural design is ingenious, and only one driving source, the driving mechanism 21, is required. It is more energy-saving and environmentally friendly, and meets the design requirements of the water-fertilizer integrated ground irrigation system.
