A spring is sleeved on the outer side of the protruding piston rod, and a protruding plate is fixedly installed at equal intervals on the left side of the outer casing corresponding to the protruding piston rod.

[0008] Preferably, a second spring is fixedly installed at the upper end of the lower circulating water tank, and the upper end of the second spring is fixedly installed on the hollow tube.

[0009] Preferably, an inclined plate is fixedly installed at the lower end of the lower circulating water tank, and a top block is provided on the left side of the inclined plate. The top block is fixedly installed on the right end of the protrusion piston rod.

[0010] Preferably, an inlet groove is provided on the lower front side of the lower circulating water tank, and a fixing plate is fixedly installed on the front side of the hollow pipe corresponding to the inlet groove.

[0011] Preferably, a central groove is provided at the middle of both the left and right ends of the incubation box, and a guide plate is fixedly installed at each of the left and right ends of the incubation box corresponding to the central groove. The guide plate is located below the circulating nozzle.

[0012] Preferably, a movable blocking plate is provided on the rear side of the lower end of the circulating nozzle, and a guide rod is slidably installed through the middle of the movable blocking plate. The guide rod is fixedly installed on the rear end of the circulating nozzle.

[0013] Preferably, grooves are provided on both the front and rear sides of the lower end of the outer casing, and baffles are slidably installed on the corresponding grooves at the lower end of the outer casing. Movable rods are fixedly installed on the ends of the baffles that are close to each other.

[0014] Preferably, the movable rods are all slidably installed on the front and rear ends of the outer casing, and springs are fixedly installed between the movable rods and the outer casing. A cleaning plate is fixedly installed at the lower end of the hollow tube corresponding to the movable rod, and the lower end of the cleaning plate is attached to the bottom of the inner end of the outer casing.

[0015] Preferably, the lower circulating water tank has a closing plate at the upper rear part, an electric push rod is fixedly installed between the closing plate and the rear end of the lower circulating water tank, a movable strip is slidably installed on the front side of the closing plate, a plurality of sliding through grooves are opened at the rear end of the lower circulating water tank corresponding to the movable strip, a spring is fixedly installed between the movable strip and the closing plate, and a clamping plate is fixedly installed at the upper end of the protrusion piston rod corresponding to the movable strip.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the starting motor drives the screw to rotate, which in turn drives the movable plate and the circulating nozzle to reciprocate back and forth. The circulating nozzle drives the hollow tube and the protruding piston rod to reciprocate back and forth synchronously. The protruding piston rod is squeezed by the protruding plate, causing it to slide in the hollow tube. The spring is adaptively compressed and resets the protruding piston rod. Water at the bottom of the outer box automatically enters the hollow tube through the inlet, causing the water in the hollow tube to move back and forth through the circulating nozzle and be evenly sprayed onto the upper side of the incubator. At the same time, the sprayed water from the circulating nozzle is also evenly sprayed onto the guide plate. The guide plate evenly permeates the sprayed water into the middle of the incubator through the central groove. Water at the bottom of the outer box also automatically enters the lower circulating water tank from the inlet groove. As the protruding piston rod reciprocates left and right, it drives the top block to move synchronously. The top block intermittently pushes against the inclined plate. The lower circulating water tank rises at the right end of the hollow tube, compressing the second spring, which then resets. As the lower circulating water tank rises rapidly, the water in it rises synchronously. The fixed blocking plate prevents water leakage from the lower circulating water tank. The water in the lower circulating water tank is evenly distributed to the lower side of the cultivation box, ensuring uniform distribution of circulating water to the upper, middle, and lower sides. This ensures that the soil in the cultivation box receives circulating water evenly from three different locations, improving the cultivation quality and efficiency of the produce. It also prevents uneven absorption of water in the soil, which can affect the quality of the produce and reduces the risk of root rot and death due to prolonged soaking of the soil. Furthermore, it avoids soil loss caused by prolonged soaking.

[0017] 2. In this invention, the starting motor drives the screw to rotate, which in turn moves the movable plate, circulating spray pipe, hollow pipe, and cleaning plate to the inner front side of the outer casing. The cleaning plate presses against the movable rod and spring three, causing the movable rod to move the baffle outward, opening the drain trough and allowing the water that has been used for a long time in the outer casing to be drained and refilled with cleaning and disinfecting solution. The movable blocking plate moves forward to block the lower opening of the circulating spray pipe, and the drain pipe is connected to the circulating spray pipe through the valve. The starting electric actuator moves the closing plate forward, covering the upper side of the lower circulating water tank. At the same time, the movable strip extends into the lower circulating water tank and is engaged with the clamping plate. The starting motor drives the circulating spray pipe, hollow pipe, and cleaning plate to move back and forth synchronously. The cleaning and disinfecting solution at the bottom of the outer casing will be discharged to the outside through the circulating spray pipe and drain pipe multiple times, which is beneficial for cleaning and disinfecting the inside of the circulating spray pipe. The cleaning plate will remove the accumulated water at the bottom of the outer casing. The material is scraped and discharged through the drains on both sides. At the same time, the cleaning and disinfecting solution in the lower circulating water tank is blocked by the closed plate and will not splash upwards into the lower side of the cultivation box. Because the movable strip is engaged with the plate, the movable strip will move back and forth left and right in the lower circulating water tank along with the protruding piston rod and the plate. This is beneficial for scraping and rinsing the accumulated material on the bottom and inner wall of the lower circulating water tank, improving the cleaning quality of the lower circulating water tank. The above is beneficial for cleaning and disinfecting the inside of the outer box, the circulating spray pipe and the inside of the lower circulating water tank. It saves time and effort, and eliminates the need to disassemble the cultivation box for cleaning and disinfection. This reduces the impact on the quality of agricultural product cultivation caused by repeated handling, disassembly and installation of the cultivation box. Moreover, the cleaning process is simple and efficient, which can reduce the situation of cultivation failure or poor cultivation quality caused by factors such as the failure to clean and disinfect the agricultural products in the cultivation box in time due to the pollution of the circulating water.

Therefore, they should not be construed as limitations on this invention.

[0021] Reference Figures 1-12An agricultural product cultivation box with a built-in water circulation mechanism includes an outer box 1, inside which a cultivation box 2 is disposed, the cultivation box 2 being slidably engaged with the upper end of the outer box 1; it also includes a circulation mechanism for spraying water to circulate the agricultural products inside the cultivation box 2, the circulation mechanism including a circulation nozzle 3 disposed on the upper side of the cultivation box 2, a movable plate 4 fixedly installed on the middle of the circulation nozzle 3, a screw 5 threadedly installed on the middle of the movable plate 4, a motor 6 disposed at the front end of the screw 5, the motor 6 being fixedly installed on the front end of the outer box 1, a hollow tube 7 fixedly connected to the lower end of the circulation nozzle 3, a lower circulating water tank 12 slidably installed on the right end of the hollow tube 7, inlet holes 8 evenly spaced on the left side of the hollow tube 7, and protrusion piston rods 9 slidably installed through the left and right ends of the hollow tube 7, the protrusion piston rods 9 being slidably installed through ... A spring 10 is fitted on the outer side of the piston rod 9, and a protruding plate 11 is fixedly installed at equal intervals on the left side of the outer box 1 corresponding to the protruding piston rod 9. A spring 2 13 is fixedly installed on the upper end of the lower circulating water tank 12, and the upper end of the spring 2 13 is fixedly installed on the hollow tube 7. An inclined plate 14 is fixedly installed on the lower end of the lower circulating water tank 12, and a top block 15 is provided on the left side of the inclined plate 14. The top block 15 is fixedly installed on the right end of the protruding piston rod 9. An inlet groove 16 is opened on the lower side of the front end of the lower circulating water tank 12, and a fixed blocking plate 17 is fixedly installed on the front side of the hollow tube 7 corresponding to the inlet groove 16. A middle groove 18 is opened in the middle of both the left and right ends of the incubation box 2, and a guide plate 19 is fixedly installed in the middle groove 18 at both the left and right ends of the incubation box 2. The guide plate 19 is located on the lower side of the circulating spray pipe 3. During operation, the starter motor 6 drives the screw 5 to rotate. The screw 5 drives the movable plate 4 and the circulating nozzle 3 to reciprocate back and forth. The circulating nozzle 3 drives the hollow tube 7 and the protruding piston rod 9 to reciprocate back and forth synchronously. The protruding piston rod 9 is squeezed by the protruding plate 11, causing it to slide in the hollow tube 7. The spring 10 is adaptively compressed and resets the protruding piston rod 9. Water at the bottom of the outer casing 1 automatically enters the hollow tube 7 through the inlet 8, thus... Water inside the hollow tube 7 moves back and forth through the circulating spray pipe 3, spraying evenly onto the upper side of the incubator 2. Simultaneously, the sprayed water from the circulating spray pipe 3 also evenly sprays onto the guide plate 19. The guide plate 19 guides the sprayed water through the central groove 18 to evenly penetrate into the middle of the incubator 2. Water at the bottom of the outer box 1 also automatically enters the lower circulating water tank 12 from the inlet groove 16. As the piston rod 9 reciprocates left and right, it drives the top block 15 to move synchronously. The top block 15 moves against the inclined plate 14. Intermittent jacking forces the lower circulating water tank 12 to rise at the right end of the hollow tube 7, compressing the second spring 13, which then acts as a reset mechanism. As the lower circulating water tank 12 rises rapidly, the water within it rises synchronously. The fixed blocking plate 17 blocks the inlet 16, preventing water leakage from the lower circulating water tank 12. The water in the lower circulating water tank 12 is then evenly distributed to the lower side of the cultivation box 2, facilitating uniform distribution of circulating water to the upper, middle, and lower sides of the cultivation box 2. This ensures that the soil in the cultivation box 2 receives circulating water evenly from three different locations, improving the cultivation quality and efficiency of the agricultural products. It also prevents uneven absorption of water in the soil, which could negatively impact the quality of the cultivated products. Furthermore, it reduces the risk of root rot and death due to prolonged soaking of the soil, which could lead to uncontrolled water absorption and soil loss.

[0022] As an embodiment of the present invention, a cleaning mechanism for cleaning the outer casing 1, the circulating nozzle 3, and the lower circulating water tank 12 is also provided. The cleaning mechanism includes a drain pipe 20 fixedly connected to the right end of the circulating nozzle 3, a valve 21 provided on the drain pipe 20, a movable blocking plate 22 provided on the rear side of the lower end of the circulating nozzle 3, a guide rod 23 slidably installed through the middle of the movable blocking plate 22, and the guide rod 23 fixedly installed on the rear end of the circulating nozzle 3. Drainage grooves 24 are provided on both the front and rear sides of the lower end of the outer casing 1, and baffles 25 are slidably installed on the lower end of the outer casing 1 corresponding to the drainage grooves 24. Movable rods 26 are fixedly installed on the close ends of the baffles 25, and the movable rods 26 are slidably installed through the grooves 24. At both ends of the outer casing 1, springs 27 are fixedly installed between the movable rod 26 and the outer casing 1. A cleaning plate 241 is fixedly installed at the lower end of the hollow tube 7 corresponding to the movable rod 26. The lower end of the cleaning plate 241 is attached to the bottom of the inner side of the outer casing 1. A closing plate 30 is provided on the upper rear side of the lower circulating water tank 12. An electric push rod 31 is fixedly installed between the closing plate 30 and the rear end of the lower circulating water tank 12. A movable strip 32 is slidably installed on the front side of the closing plate 30. Multiple sliding through slots are opened at the rear end of the lower circulating water tank 12 corresponding to the movable strip 32. A spring 33 is fixedly installed between the movable strip 32 and the closing plate 30. A clamping plate 34 is fixedly installed at the upper end of the protrusion piston rod 9 corresponding to the movable strip 32. During operation, the starter motor 6 drives the screw 5 to rotate. The screw 5 moves the movable plate 4, the circulating spray pipe 3, the hollow pipe 7, and the cleaning plate 241 to the inner front side of the outer casing 1. The cleaning plate 241 squeezes the movable rod 26 and the spring 3 27. The movable rod 26 moves the baffle 25 outward, opening the drain trough 24 to drain the water that has been used for a long time in the outer casing 1 and refill it with cleaning and disinfecting solution. The movable blocking plate 22 moves forward to block the lower opening of the circulating spray pipe 3. The drain pipe 20 is connected to the circulating spray pipe 3 through the valve 21. When the ring nozzle 3 is connected, the electric actuator 31 drives the closing plate 30 forward, covering the upper side of the lower circulating water tank 12. At the same time, the movable strip 32 extends into the lower circulating water tank 12 and is engaged with the clamping plate 34. The motor 6 is started, driving the circulating nozzle 3, hollow tube 7, and cleaning plate 241 to move back and forth synchronously. The cleaning and disinfection solution at the bottom of the outer casing 1 will pass through the circulating nozzle 3 and drain pipe 20 multiple times and be discharged to the outside, which is beneficial for cleaning and disinfecting the inside of the circulating nozzle 3. Plate 241 scrapes away the accumulated material at the bottom of the outer box 1, allowing it to drain through the drainage channels 24 on both the front and rear sides. At the same time, the cleaning and disinfecting solution in the lower circulating water tank 12 is blocked by the closing plate 30, preventing it from splashing upwards into the lower side of the cultivation box 2. Because the movable strip 32 is engaged with the clamping plate 34, the movable strip 32 moves back and forth in the lower circulating water tank 12 along with the protruding piston rod 9 and the clamping plate 34. This facilitates scraping and rinsing away the accumulated material at the bottom and inner wall of the lower circulating water tank 12, improving the cleaning quality of the lower circulating water tank 12. The above methods are beneficial for cleaning and disinfecting the interior of the outer box 1, the circulating spray pipe 3, and the interior of the lower circulating water tank 12, saving time and effort. It eliminates the need to disassemble the cultivation box 2 for cleaning and disinfection, reducing the impact on the quality of agricultural product cultivation caused by repeated handling, disassembly, and installation of the cultivation box 2. Moreover, the cleaning process is simple and efficient, reducing the chances of cultivation failure or poor cultivation quality caused by factors such as untimely cleaning and disinfection of the circulating water in the cultivation box 2.

[0023] Working principle: In use, the starting motor 6 drives the screw 5 to rotate, which in turn drives the movable plate 4 and the circulating nozzle 3 to reciprocate back and forth. The circulating nozzle 3 drives the hollow tube 7 and the protruding piston rod 9 to reciprocate back and forth synchronously. The protruding piston rod 9 is squeezed by the protruding plate 11, causing it to slide in the hollow tube 7. The spring 10 is adaptively compressed and resets the protruding piston rod 9. Water at the bottom of the outer box 1 automatically enters the hollow tube 7 through the inlet 8, allowing the water in the hollow tube 7 to move back and forth through the circulating nozzle 3 and be evenly sprayed onto the upper side of the incubator 2. At the same time, the sprayed water from the circulating nozzle 3 is also evenly sprayed onto the guide plate 19, which guides the sprayed water to permeate evenly into the middle of the incubator 2 through the central groove 18. Inside, water at the bottom of the outer box 1 will automatically enter the lower circulating water tank 12 from the inlet 16. As the piston rod 9 moves back and forth, it will drive the top block 15 to move synchronously. The top block 15 will exert intermittent upward force on the inclined plate 14, causing the lower circulating water tank 12 to rise at the right end of the hollow tube 7, compressing the second spring 13. The second spring 13 will play a reset role. When the lower circulating water tank 12 rises rapidly, it will drive the water in the lower circulating water tank 12 to rise synchronously. The fixed block plate 17 will block the inlet 16 to prevent the water in the lower circulating water tank 12 from leaking out. The water in the lower circulating water tank 12 will be evenly thrown to the lower side of the cultivation box 2, which is conducive to the even spraying of circulating water on the upper, middle and lower sides of the cultivation box 2, and helps to ensure the soil of agricultural products in the cultivation box 2. The ability to uniformly obtain circulating water from three different locations improves the cultivation quality and efficiency of agricultural products in cultivation box 2. It also avoids uneven soil absorption, which could negatively impact cultivation quality and reduce the risk of root rot and death due to prolonged soil soaking. Furthermore, it minimizes soil loss caused by uncontrolled water absorption. The starting motor 6 drives the screw 5 to rotate, which in turn moves the movable plate 4, circulating nozzle 3, hollow pipe 7, and cleaning plate 241 to the inner front of the outer box 1. The cleaning plate 241 presses against the movable rod 26 and spring 3 27, causing the movable rod 26 to move the baffle 25 outwards, opening the drain trough 24 to drain the water that has been used for a long time in the outer box 1, allowing for the refilling of the cleaning water. Disinfectant pushes the movable blocking plate 22 forward, blocking the lower opening of the circulating spray pipe 3. Valve 21 connects the drain pipe 20 to the circulating spray pipe 3. The electric actuator 31 moves the closing plate 30 forward, covering the upper side of the lower circulating water tank 12. Simultaneously, the movable strip 32 extends into the lower circulating water tank 12 and engages with the clamping plate 34. The motor 6 is activated, causing the circulating spray pipe 3, hollow pipe 7, and cleaning plate 241 to move synchronously back and forth. The cleaning and disinfecting solution at the bottom of the outer casing 1 is repeatedly discharged through the circulating spray pipe 3 and drain pipe 20, facilitating cleaning and disinfection of the inside of the circulating spray pipe 3. The cleaning plate 241 scrapes away the accumulated material at the bottom of the outer casing 1, discharging it through the drain channels 24 on both the front and rear sides. Meanwhile...The cleaning and disinfecting solution in the lower circulating water tank 12 is blocked by the closing plate 30 and will not splash upwards into the lower side of the cultivation tank 2. Because the movable strip 32 is engaged with the clamping plate 34, the movable strip 32 moves back and forth in the lower circulating water tank 12 along with the protruding piston rod 9 and the clamping plate 34. This facilitates scraping and rinsing of accumulated debris on the inner bottom and inner wall of the lower circulating water tank 12, improving the cleaning quality of the lower circulating water tank 12. This process is beneficial for cleaning and disinfecting the interior of the outer tank 1, the circulating spray pipe 3, and the interior of the lower circulating water tank 12, saving time and effort. It eliminates the need to disassemble the cultivation tank 2 for cleaning and disinfection, reducing the impact on agricultural product cultivation quality caused by repeated handling, disassembly, and installation of the cultivation tank 2. Furthermore, the cleaning process is simple and efficient, reducing the likelihood of cultivation failure or poor cultivation quality due to factors such as untimely cleaning and disinfection of the circulating water.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
