Description

Technical Field

[0001] The invention relates to the technical field of hydroponic planting equipment, and in particular to an automatic flushing system for a hydroponic cucumber planting tray rack. Background Art

[0002] As an important part of hydroponic vegetable production, cleaning of the planting tray is one of the key technical measures to improve the comprehensive benefits of vegetable production. In order to achieve the planting effect, nutrient solution or nutrient soil will be stored in the planting tray, and the nutrient solution and nutrient soil need to be replaced at regular intervals. Before replacement, the planting tray needs to be thoroughly cleaned.

[0003] At present, the cleaning work is done manually, which is inefficient, has poor cleaning effect, requires a large amount of labor, and is highly dependent on labor. In addition, planting trays are generally provided with planting holes. Therefore, when cleaning the planting trays, if the water pressure is too high, water will overflow and affect the surrounding environment and cause a waste of water resources. However, if the water pressure is too low, it will be difficult to clean the impurities attached to the inner wall of the planting tray, which will affect the next vegetable production effect. In addition, the general cleaning of the planting trays is to circulate the cleaning liquid once, and it will not be repeatedly cleaned, which will waste water resources. Therefore, the present invention solves the shortcomings of the above technical problems. Summary of the invention

[0004] Based on the above-mentioned existing technical problems, the present invention proposes an automatic flushing system for a hydroponic cucumber planting tray rack.

[0005] The present invention proposes an automatic flushing system for a hydroponic cucumber planting tray rack, comprising a rack for cucumber vines to wrap around, a support frame being installed on the upper surface of a bottom plate of the rack, hydroponic tubes being evenly spaced and arranged on the upper surface of the support frame, planting tubes being fixedly connected and distributed in a linear array on the upper surface of the hydroponic tubes, backwashing mechanisms being arranged at both ends of the hydroponic tubes, a brushing mechanism being arranged inside the hydroponic tubes, and a sealing mechanism being arranged on the inner wall of the upper end of the planting tubes.

[0006] The backwashing mechanism filters the cleaning liquid flushed into the hydroponic tube and then backwashes the hydroponic tube.

[0007] The scrubbing mechanism is opened and rotated inside the hydroponic tube to scrub the inner wall of the tube.

[0008] Wherein, the sealing mechanism performs a sealing action on the feed opening of the planting tube during flushing.

[0009] Preferably, the backwashing mechanism includes a water tank arranged on the upper surface of the bottom plate of the frame, and the upper surface of the water tank is evenly distributed and fixedly connected with Y-shaped conduits, each branch of which is equipped with a one-way valve. The connecting pipe of the Y-shaped conduit is fixedly connected to the inside of the corresponding hydroponic tube, and a collection box is installed on the upper surface of the water tank.

[0010] Through the above technical scheme, in order to realize the reuse of hydroponic tubes, they can be rinsed after planting to facilitate their continued use next time. A water tank with a water pump inside is set at the frame, and the one-way valve on the Y-shaped conduit is controlled to open, so that cleaning liquid can be pumped into the hydroponic tube. When the cleaning liquid flows in the hydroponic tube, the flushing action can be achieved. In order to recycle the cleaning liquid and save water resources, the cleaning liquid is reversely circulated in the hydroponic tube. The reversely circulated cleaning liquid flows into the collection box along the other branch of the Y-shaped conduit, and after being filtered in the collection box, it enters the water tank through a connecting pipe with a valve for reuse.

[0011] Preferably, the backwash mechanism also includes a drainage pipe fixedly connected to one end of the hydroponic tube opposite to the Y-shaped conduit, the lower ends of the plurality of drainage pipes are fixedly connected to a water distribution pipe, one end of the water distribution pipe is fixedly connected to a T-shaped branch pipe through a branch pipe, the transverse branch end face of the branch pipe is fixedly connected to a water inlet pipe with a one-way valve, and the radial branch end face of the branch pipe is fixedly connected to a reverse water pipe with a one-way valve.

[0012] Through the above technical scheme, in order to filter the cleaning liquid flushed in the hydroponic tube and then reversely flush the hydroponic tube, the circulating cleaning liquid is concentrated from the drainage pipe into the water distribution pipe, and then blocked by the one-way valve of the reverse water pipe, so that the circulating cleaning liquid is concentrated through the water inlet pipe, and after the filtration is completed, it flows back from the reverse water pipe to the water distribution pipe, so that the liquid in the water distribution pipe is dispersed to the drainage pipe, and reversely circulates through the hydroponic tube to realize its circulation cleaning.

[0013] Preferably, one end of the water inlet pipe is fixedly connected to a Y-shaped filter, the water outlet end of the Y-shaped filter is fixedly connected to a T-shaped elbow, one end of the T-shaped elbow is rotatably sealed with an end cover, and the other end of the T-shaped elbow is fixedly connected to a Z-shaped branch pipe with a one-way valve.

[0014] Through the above technical scheme, in order to filter the circulating cleaning liquid and then circulate it in reverse to automatically flush the hydroponic tube again, the one-way valve on the water inlet pipe is opened, so that the cleaning liquid flows to the Y-shaped filter. The Y-shaped filter is a common pipeline filter, which is usually used to filter impurities in liquid fluid systems. The Y-shaped filter is usually installed on the pipeline, and the fluid is allowed to flow in a certain direction through the water outlet in the center, while the impurities therein are trapped inside the filter. The filtered cleaning liquid then enters the Z-shaped branch pipe through the T-shaped elbow to achieve reverse circulation, and after the hydroponic tube is cleaned, the excess liquid is discharged by opening the end cover.

[0015] Preferably, the backwash mechanism further comprises a filter tube with a filter core, one end of the filter tube is fixedly connected to the upper end of the Z-shaped branch pipe, and the water outlet end of the filter tube is fixedly connected to the water inlet end of the reverse water pipe.

[0016] Through the above technical scheme, in order to further filter the cleaning liquid and improve the cleaning effect of the hydroponic tube, the water level of the initially filtered cleaning liquid is raised through the Z-shaped branch pipe. The cleaning liquid with the raised water level falls into the filter tube due to gravity and is filtered by the filter element inside it. Then the one-way valve of the reverse water pipe is opened, and the filtered cleaning liquid flows in reverse to the hydroponic tube for cleaning.

[0017] Preferably, the scrubbing mechanism includes fixed blocks fixedly connected to the symmetrical surfaces at both ends of the hydroponic tube, wherein one side surface of the fixed blocks close to the inside of the hydroponic tube is rotatably connected to a supporting round block through a bearing, and another side surface of the fixed block close to the inside of the hydroponic tube is connected to another supporting round block through the output shaft of a motor installed inside the fixed block, and the opposite side surfaces of the two supporting round blocks are rotatably connected to adjusting discs.

[0018] Through the above technical solution, when the cleaning liquid is flushing the hydroponic tube, in order to peel off and clean the impurities adhered to the inner wall of the hydroponic tube, the two supporting round blocks can be rotated simultaneously, so that the inside of the hydroponic tube can be scraped and swept. In order to prevent the unfolded brushing mechanism from affecting the insertion of cucumbers during hydroponic planting, the two adjusting discs can be rotated synchronously to achieve the contraction of the brushing mechanism.

[0019] Preferably, the brushing mechanism also includes telescopic grooves distributed in a circular array on the surface of one side of the supporting circle block close to the adjusting disc, a telescopic rod is slidably connected to the inner wall of the telescopic groove, and a brushing rod is fixedly connected to the outer surface of the telescopic rod corresponding to the two ends of the hydroponic tube.

[0020] Through the above technical scheme, when cleaning the hydroponic tube, the brushing mechanism is unfolded and contacts the inner wall of the hydroponic tube, so that the impurities adhered to the inner wall can be peeled off and then washed when it rotates, so that the telescopic rod moves outward on the inner wall of the telescopic slide and extends, so that the brushing rod attached to the outer surface of the supporting round block is unfolded and contacts the inner wall of the hydroponic tube, and then the inner wall of the hydroponic tube can be cleaned when the brushing rod rotates.

[0021] Preferably, a servo motor is fixedly installed inside one of the supporting round blocks, and a rotating rod is fixedly connected to the outer surface of the output shaft of the servo motor. The rotating rod extends through the supporting round block at this end and is fixedly connected to the surfaces of the two adjusting discs. The surfaces of the adjusting discs are distributed in a ring array and are provided with arc-shaped adjusting grooves. An adjusting rod is fixedly connected to one side surface of the telescopic rod. The outer surface of the adjusting rod passes through the adjusting groove and is slidably engaged with the inner wall thereof.

[0022] Through the above technical scheme, in order to control the telescopic rod to move on the inner wall of the telescopic slide groove to realize the unfolding of the brush rod, the rotation of the rotating rod is controlled by the servo motor. Since the two ends of the rotating rod are connected to the adjusting disk, the two adjusting disks can be driven to rotate, so that the adjusting rod moves along the path of the adjusting groove, and then the telescopic rod connected to the adjusting rod is pulled to move in the telescopic slide groove to drive the brush rod to unfold.

[0023] Preferably, the sealing mechanism includes a fixing ring fixedly connected to the inner wall of the upper end of the planting tube, the upper surface of the fixing ring is distributed in a circular array with sealing blocks in sliding contact, the upper surface of the sealing blocks is provided with limiting grooves distributed in a circular array, the surface of the sealing block is fixedly connected to a limiting rod, and the outer surface of the lower end of the limiting rod is slidably connected to the inner wall of the limiting groove.

[0024] Through the above technical scheme, in order to facilitate the effective cleaning of the inside of the hydroponic tube, multiple sealing blocks are moved toward the center of the fixed ring at the same time during cleaning, and then the multiple sealing blocks can form a closed circular block to seal the circular hole of the fixed ring. When the sealing block moves, the limit rod can slide on the inner wall of the limit groove.

[0025] Preferably, the sealing mechanism also includes an adjusting tooth ring rotatably connected to the outer surface of the upper end of the planting tube through a bearing, the inner top surface of the adjusting tooth ring is in sliding contact with the upper surface of the sealing block, the upper surface of the adjusting tooth ring is distributed in an annular array and is provided with movable holes, the inner wall of the movable hole is slidably connected to the outer surface of the upper end of the limiting rod, the upper surface of the support frame is rotatably connected with a plurality of adjusting screws through a support plate, a plurality of the adjusting screws are meshed with the corresponding adjusting tooth rings, the upper surface of the support frame is installed with a linkage shell through a support column, and the outer surfaces of the plurality of adjusting screws are rotatably connected to the surface of the linkage shell through bearings.

[0026] Through the above technical scheme, in order to drive the sealing block to move and realize the closing and opening of the pipe mouth of the planting tube, the adjusting gear ring is rotated, so that the limit rod can be moved on the inner wall path of the movable hole, and then the sealing block is pulled to move on the surface of the fixed ring, so that the pipe mouth of the planting tube can be adjusted, and in order to realize the synchronous rotation of multiple adjusting gear rings, the meshing adjusting gear rings can be rotated by the synchronous rotation of the adjusting screw, and a pulley assembly is provided inside the linkage shell, so that the synchronous rotation of multiple adjusting screws can be realized, and then the sealing adjustment of the hydroponic tube can be completed when the hydroponic tube is cleaned.

[0027] The beneficial effects of the present invention are:

[0028] 1. By setting up a backwashing mechanism, the cleaning liquid can be filtered and then backwashed to the hydroponic tube. During the adjustment process, the cleaning liquid flows to the Y-shaped filter for filtration and then enters the Z-shaped branch pipe through the T-shaped elbow to achieve reverse circulation. The water level of the initially filtered cleaning liquid is raised through the Z-shaped branch pipe. The cleaning liquid with the raised water level falls into the filter tube due to gravity and is filtered by the filter element inside it. Then the one-way valve of the reverse water pipe is opened, and the filtered cleaning liquid flows back to the hydroponic tube for cleaning, thereby saving water resources and making the hydroponic tube cleaning effect better.

[0029] 2. By setting up a brushing mechanism, the inner wall of the hydroponic tube can be scraped when flushing it, so that impurities can be peeled off. During the adjustment process, the rotation of the rotating rod is controlled by the servo motor. Since the two ends of the rotating rod are connected to the adjusting disc, the two adjusting discs can be driven to rotate, so that the adjusting rod moves along the path of the adjusting groove, and then the telescopic rod connected to the adjusting rod is pulled to move in the telescopic slide groove to drive the brushing rod to unfold and contact the inner wall of the hydroponic tube. Then, when the brushing rod rotates, the inner wall of the hydroponic tube can be scraped, and the scraped impurities flow to the Y-shaped filter and the filter tube with the cleaning liquid for filtration, or flow to the collection box for filtration, thereby realizing the automation of hydroponic tube cleaning and improving the cleaning effect.

[0030] 3. By setting up a sealing mechanism, the hydroponic tube can be sealed during cleaning, so that the flushing effect of the hydroponic tube is better when the cleaning water pressure is increased. During the adjustment process, by rotating the adjusting gear ring, the limit rod can be moved along the inner wall path of the movable hole, and then the sealing block is pulled to move on the surface of the fixed ring. Therefore, the tube mouth of the planting tube can be adjusted to achieve its sealing action, which can prevent the cleaning liquid from seeping out during flushing.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Reference Figure 1-Figure 12 A hydroponic cucumber planting tray rack automatic flushing system comprises a rack 1 for cucumber vine winding, a support frame 2 is installed on the upper surface of the bottom plate of the rack 1, hydroponic tubes 3 are evenly distributed on the upper surface of the support frame 2, and planting tubes 4 are fixedly connected to the upper surface of the hydroponic tubes 3 in a linear array, backwashing mechanisms 5 are provided at both ends of the hydroponic tubes 3, a brushing mechanism 7 is provided inside the hydroponic tubes 3, and a sealing mechanism 9 is provided on the inner wall of the upper end of the planting tube 4.

[0046] The backwashing mechanism 5 filters the cleaning liquid flushed into the hydroponic tube 3 and then backwashes the hydroponic tube 3 .

[0047] In order to realize the reuse of the hydroponic tube 3, it is rinsed after the planting is completed, so that it can be used next time. The backwashing mechanism 5 includes a water tank 51 arranged on the upper surface of the bottom plate of the frame 1. The upper surface of the water tank 51 is evenly distributed and fixedly connected with Y-shaped conduits 52, each branch of which is equipped with a one-way valve. The connecting pipe of the Y-shaped conduit 52 is fixedly connected with the inside of the corresponding hydroponic tube 3. The water tank 51 with an internal water pump is arranged at the frame 1. The one-way valve on the Y-shaped conduit 52 is controlled to open, and cleaning liquid can be pumped into the hydroponic tube 3. When the cleaning liquid flows in the hydroponic tube 3, the flushing action can be achieved. In order to recycle the cleaning liquid and save water resources, a collecting box 53 is installed on the upper surface of the water tank 51. The cleaning liquid flows back through the hydroponic tube 3. The reversely circulated cleaning liquid flows into the collecting box 53 along the other branch of the Y-shaped conduit 52, and after being filtered in the collecting box 53, it enters the water tank 51 through the connecting pipe with a valve for reuse.

[0048] In order to filter the cleaning liquid flushed in the hydroponic tube 3 and then backwash the hydroponic tube 3, the backwashing mechanism 5 also includes a drain pipe 54 fixedly connected to one end of the Y-shaped conduit 52 opposite to the hydroponic tube 3, and the lower ends of the multiple drain pipes 54 are fixedly connected to a water distribution pipe 55, and one end of the water distribution pipe 55 is fixedly connected to a T-shaped branch pipe 56 through a branch pipe, and the transverse branch pipe end face of the branch pipe 56 is fixedly connected to an inlet pipe 57 with a one-way valve, and the radial branch pipe end face of the branch pipe 56 is fixedly connected to a reverse water pipe 58 with a one-way valve. The circulating cleaning liquid flows from the drain pipe 54 into the water distribution pipe 55, and then is blocked by the one-way valve of the reverse water pipe 58, so that the circulating cleaning liquid is concentrated through the inlet pipe 57, and after filtering, it flows back from the reverse water pipe 58 to the water distribution pipe 55, so that the liquid in the water distribution pipe 55 is dispersed to the drain pipe 54 again, and flows back through the hydroponic tube 3 to achieve its circulation cleaning.

[0049] In order to filter the circulating cleaning liquid and then circulate it in reverse to automatically rinse the hydroponic tube 3 again, one end of the water inlet pipe 57 is fixedly connected to the Y-shaped filter 59, and the water outlet end of the Y-shaped filter 59 is fixedly connected to a T-shaped elbow 60. One end of the T-shaped elbow 60 is rotatably sealed with an end cover 61, and the other end of the T-shaped elbow 60 is fixedly connected to a Z-shaped branch pipe 62 with a one-way valve. The one-way valve on the water inlet pipe 57 is opened to allow the cleaning liquid to flow to the Y-shaped filter 59. The Y-shaped filter 59 is a common pipeline filter, which is usually used to filter impurities in a liquid fluid system. The Y-shaped filter 59 is usually installed on a pipeline, and the water outlet at the center allows the fluid to flow in a certain specific direction, while retaining the impurities therein inside the filter. Then, the filtered cleaning liquid enters the Z-shaped branch pipe 62 through the T-shaped elbow 60 to achieve reverse circulation, and after the cleaning of the hydroponic tube 3 is completed, the excess liquid is discharged by opening the end cover 61.

[0050] In order to further filter the cleaning liquid and improve the cleaning effect of the hydroponic tube 3, the backwashing mechanism 5 also includes a filter tube 63 with a filter core. One end of the filter tube 63 is fixedly connected to the upper end of the Z-shaped branch pipe 62, and the water outlet end of the filter tube 63 is fixedly connected to the water inlet end of the reverse water pipe 58. The water level of the initially filtered cleaning liquid is raised through the Z-shaped branch pipe 62. The cleaning liquid with the raised water level falls into the filter tube 63 due to gravity and is filtered by the filter core inside the filter tube 63. Then the one-way valve of the reverse water pipe 58 is opened, and the filtered cleaning liquid flows in reverse to the hydroponic tube 3 for cleaning.

[0051] By setting up the backwashing mechanism 5, the cleaning liquid can be filtered and then backwashed to the hydroponic tube 3. During the adjustment process, the cleaning liquid flows to the Y-shaped filter 59 for filtration and then enters the Z-shaped branch pipe 62 through the T-shaped elbow 60 to achieve reverse circulation. The water level of the initially filtered cleaning liquid is raised through the Z-shaped branch pipe 62. The cleaning liquid with the raised water level falls into the filter tube 63 due to gravity and is filtered by the filter element inside it. Then the one-way valve of the reverse water pipe 58 is opened, and the filtered cleaning liquid flows back to the hydroponic tube 3 for cleaning, thereby saving water resources and making the cleaning effect of the hydroponic tube 3 better.

[0052] The scrubbing mechanism 7 is opened inside the hydroponic tube 3 and rotates to scrub the inner wall of the tube.

[0053] When the cleaning liquid is flushing the hydroponic tube 3, in order to peel off and clean the impurities adhered to the inner wall of the hydroponic tube 3, the scrubbing mechanism 7 includes fixed blocks 71 fixedly connected to the symmetrical surfaces at both ends of the hydroponic tube 3, one of the fixed blocks 71 is rotatably connected to a supporting round block 72 on a side surface close to the inside of the hydroponic tube 3 through a bearing, and the other fixed block 71 is connected to another supporting round block 72 on a side surface close to the inside of the hydroponic tube 3 through the output shaft of the motor installed inside it. By rotating the two supporting round blocks 72 at the same time, the inside of the hydroponic tube 3 can be scraped and swept. In order to prevent the unfolded scrubbing mechanism 7 from affecting the insertion of cucumbers during hydroponic planting, the opposite side surfaces of the two supporting round blocks 72 are rotatably connected to adjusting discs 73. The two adjusting discs 73 rotate synchronously to achieve the contraction of the scrubbing mechanism 7.

[0054] In order to enable the scrubbing mechanism 7 to unfold and contact the inner wall of the hydroponic tube 3 when cleaning the hydroponic tube 3, so that the impurities adhered to the inner wall can be peeled off and then rinsed when rotating, the scrubbing mechanism 7 also includes telescopic slide grooves 74 distributed in a ring array and arranged on the surface of one side of the supporting round block 72 close to the adjusting disk 73. The inner wall of the telescopic slide groove 74 is slidably clamped with a telescopic rod 75. The outer surfaces of the telescopic rods 75 corresponding to the two ends of the hydroponic tube 3 are fixedly connected with scrubbing rods 76. The telescopic rods 75 move outwardly and extend along the inner wall of the telescopic slide groove 74, so that the scrubbing rods 76 attached to the outer surface of the supporting round block 72 are unfolded and contact the inner wall of the hydroponic tube 3. Then, the inner wall of the hydroponic tube 3 can be cleaned when the scrubbing rods 76 rotate.

[0055] In order to control the telescopic rod 75 to move on the inner wall of the telescopic slide 74 and realize the expansion of the scrubbing rod 76, a servo motor 77 is fixedly installed inside one of the support round blocks 72, and a rotating rod 78 is fixedly connected to the outer surface of the output shaft of the servo motor 77. The rotating rod 78 extends through the support round block 72 at this end and is fixedly connected to the surfaces of two adjusting disks 73. The surfaces of the adjusting disks 73 are distributed in a ring array and penetrated by arc-shaped adjusting grooves 79. An adjusting rod 80 is fixedly connected to the surface of one side of the telescopic rod 75. The outer surface of the adjusting rod 80 penetrates the adjusting groove 79 and is slidably engaged with the inner wall thereof. The rotation of the rotating rod 78 is controlled by the servo motor 77. Since the two ends of the rotating rod 78 are connected to the adjusting disk 73, the two adjusting disks 73 can be driven to rotate, so that the adjusting rod 80 moves along the path of the adjusting groove 79, thereby pulling the telescopic rod 75 connected with the adjusting rod 80 to move in the telescopic slide 74 and drive the scrubbing rod 76 to expand.

[0056] By providing the scrubbing mechanism 7, the inner wall of the hydroponic tube 3 can be scraped when flushing the hydroponic tube 3, so that impurities can be peeled off. During the adjustment process, the rotating rod 78 is controlled to rotate by the servo motor 77. Since the two ends of the rotating rod 78 are connected to the adjusting disc 73, the two adjusting discs 73 can be driven to rotate, so that the adjusting rod 80 moves along the path of the adjusting groove 79, and then the telescopic rod 75 connected to the adjusting rod 80 is pulled to move in the telescopic slide groove 74 to drive the scrubbing rod 76 to unfold and contact the inner wall of the hydroponic tube 3. Then, when the scrubbing rod 76 rotates, the inner wall of the hydroponic tube 3 can be scraped, and the scraped impurities flow to the Y-shaped filter 59 and the filter tube 63 for filtration with the cleaning liquid, or flow to the collection box 53 for filtration, thereby realizing the automation of the cleaning of the hydroponic tube 3 and improving the cleaning effect.

[0057] The sealing mechanism 9 performs a sealing action on the feed opening of the planting tube 4 during flushing.

[0058] In order to facilitate the effective cleaning of the inside of the hydroponic tube 3, the sealing mechanism 9 includes a fixing ring 91 fixedly connected to the inner wall of the upper end of the planting tube 4. The upper surface of the fixing ring 91 is distributed in a circular array and is in sliding contact with sealing blocks 92. The upper surface of the sealing block 92 is distributed in a circular array and has limiting grooves 93. The surface of the sealing block 92 is fixedly connected to a limiting rod 94. The outer surface of the lower end of the limiting rod 94 is slidably connected to the inner wall of the limiting groove 93. During cleaning, multiple sealing blocks 92 are simultaneously moved toward the center of the fixing ring 91, and then multiple sealing blocks 92 can form a closed circular block to seal the circular hole of the fixing ring 91. When the sealing block 92 moves, the limiting rod 94 can slide on the inner wall of the limiting groove 93.

[0059] In order to drive the sealing block 92 to move and realize the closing and opening of the tube mouth of the planting tube 4, the sealing mechanism 9 also includes an adjusting toothed ring 95 which is rotatably connected to the outer surface of the upper end of the planting tube 4 through a bearing. The inner top surface of the adjusting toothed ring 95 is in sliding contact with the upper surface of the sealing block 92. The upper surface of the adjusting toothed ring 95 is distributed in an annular array and is penetrated by moving holes 96. The inner wall of the moving hole 96 is slidably connected to the outer surface of the upper end of the limiting rod 94. By rotating the adjusting toothed ring 95, the limiting rod 94 can be moved along the inner wall path of the moving hole 96, thereby pulling the sealing block 92. 2 moves on the surface of the fixing ring 91, so that the pipe mouth of the planting tube 4 can be adjusted. In order to realize the synchronous rotation of the multiple adjusting toothed rings 95, the upper surface of the supporting frame 2 is rotatably connected with multiple adjusting screws 97 through the supporting plate. The multiple adjusting screws 97 are meshed with the corresponding adjusting toothed rings 95. Through the synchronous rotation of the adjusting screws 97, the meshed adjusting toothed rings 95 can be rotated, and a pulley assembly is arranged inside the linkage housing 98, so that the synchronous rotation of the multiple adjusting screws 97 can be realized, and then the sealing adjustment of the hydroponic tube 3 can be completed when the hydroponic tube 3 is cleaned.

[0060] By setting up the sealing mechanism 9, the hydroponic tube 3 can be sealed during cleaning, so that the flushing effect of the hydroponic tube 3 is better when the cleaning water pressure is increased. During the adjustment process, by rotating the adjusting gear ring 95, the limit rod 94 can be moved along the inner wall path of the movable hole 96, thereby pulling the sealing block 92 to move on the surface of the fixed ring 91, so that the pipe mouth of the planting tube 4 can be adjusted to achieve its sealing action, which can prevent the cleaning liquid from seeping out during flushing.

[0061] Working principle: In a specific embodiment of the present invention, after the nutrient solution in the hydroponic tube 3 is processed, the inside thereof is flushed. During flushing, the two ends of the hydroponic tube 3 are closed by the fixed block 71, and the sealing mechanism 9 closes the pipe opening of the planting tube 4. Therefore, when the sealing mechanism 9 is actuated, the three adjusting screws 97 are controlled to rotate by the pulley assembly inside the linkage housing 98, so that the corresponding meshing multiple adjusting tooth rings 95 rotate on the outer surfaces of their respective planting tubes 4, so that the limiting rod 94 moves on the inner wall path of the moving hole 96, thereby driving the sealing block 92 to move toward the center of the circle on the upper surface of the fixed ring 91, and then the multiple sealing blocks 92 can form a closed circular block to seal the pipe opening of the planting tube 4;

[0062] After the hydroponic tube 3 is closed, the scrubbing rod 76 is unfolded inside the hydroponic tube 3. When it is unfolded, the rotating rod 78 is controlled to rotate by the servo motor 77. Since both ends of the rotating rod 78 are connected to the adjusting disc 73, the two adjusting discs 73 can be driven to rotate, so that the adjusting rod 80 moves along the path of the adjusting groove 79, and then the telescopic rod 75 connected to the adjusting rod 80 is pulled to move in the telescopic slide groove 74, so that the scrubbing rod 76 attached to the outer surface of the supporting round block 72 is unfolded and contacts the inner wall of the hydroponic tube 3.

[0063] Then, the hydroponic tube 3 is flushed. A certain amount of cleaning liquid is introduced into the hydroponic tube 3 through the Y-shaped conduit 52 by the pump body in the water tank 51. Due to the water pressure, the cleaning liquid flushes inside the hydroponic tube 3. During the flushing, the motor installed inside the other fixed block 71 drives one of the supporting round blocks 72 to rotate, and the other supporting round block 72 rotates under the connection of the brush rod 76, so that the brush rod 76 brushes the inner wall of the hydroponic tube 3, and the impurities dropped by the brushing are flushed away together with the cleaning liquid.

[0064] The circulating cleaning liquid flows from the drainage pipe 54 into the water distribution pipe 55, and then is blocked by the one-way valve of the reverse water pipe 58, so that the circulating cleaning liquid is concentrated through the water inlet pipe 57. The one-way valve on the water inlet pipe 57 is opened to allow the cleaning liquid to flow to the Y-shaped filter 59, which can retain impurities in the cleaning liquid inside the filter. Then, the filtered cleaning liquid enters the Z-shaped branch pipe 62 through the T-shaped elbow 60, and the water level of the initially filtered cleaning liquid is raised through the Z-shaped branch pipe 62. The cleaning liquid with the raised water level falls into the filter pipe 63 due to gravity and is filtered by the filter element inside it. Then, the one-way valve of the reverse water pipe 58 is opened, and the filtered cleaning liquid flows in reverse to the hydroponic tube 3 for cleaning, and finally flows into the collection box 53 along the other branch of the Y-shaped conduit 52, and after being filtered in the collection box 53, it enters the water tank 51 through the connecting pipe with a valve for reuse;

[0065] After one backwashing is completed, a certain amount of cleaning liquid is continuously pumped into the hydroponic tube 3 by the pump body in the water tank 51 for further cleaning until the hydroponic tube 3 is cleaned.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
