Description

Technical Field

[0001] This utility model relates to the field of agricultural cultivation technology, specifically to an agronomic cultivation drainage device. Background Technology

[0002] In the prior art, such as Chinese Patent Publication No. CN214430870U, an agronomic cultivation drainage device is disclosed, which includes a cultivation pipe, a second filter plate placed inside the cultivation pipe, and a first filter plate fixedly connected to one side of the second filter plate.

[0003] Although it can cultivate vegetables, debris will fall into the water storage tank and enter the drainage device with the water flow. Because it is inconvenient to clean the debris, it will rot in the drainage device over time, thus polluting the incoming water, affecting the water quality, and contaminating the vegetables, thus affecting the quality of the vegetables. Therefore, we propose a new type of agronomic cultivation drainage device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an agricultural cultivation drainage device that uses a filter box in conjunction with a filter cylinder to filter the drainage. This not only ensures smooth drainage but also facilitates the collection and cleaning of debris and fallen leaves in the cultivation trough, preventing them from accumulating at the drainage point and mixing with the influent, thus affecting water quality.

[0005] This utility model is achieved through the following technical solution:

[0006] A drainage device for agronomic cultivation is provided, including a drainage pipe installed at the drainage outlet at the bottom of the cultivation trough. The drainage pipe includes an L-shaped connecting pipe and an inverted U-shaped siphon pipe connected in sequence. A filter box is connected to the water inlet end of the connecting pipe. A filter cylinder is connected to the top wall of the inner cavity of the filter box. A water inlet pipe is embedded in the top wall of the filter box. The lower end of the water inlet pipe extends into the inside of the filter cylinder. A cleaning ring is connected to the inside of the filter cylinder through a drive assembly. A cleaning brush that can fit against the inner wall of the filter cylinder is installed on the outer ring wall of the cleaning ring.

[0007] Furthermore, the drive assembly includes a motor housing installed at the center of the top wall inside the filter cartridge, a drive motor installed inside the motor housing, a threaded rod vertically connected to the output end of the drive motor, a nut threaded onto the threaded rod, and a connection between the nut and the cleaning ring via a connecting plate. It also includes a smooth rod vertically installed on the top wall inside the filter cartridge and on the side of the drive motor, with the lower end of the smooth rod penetrating the connecting plate and slidably connected to the connecting plate.

[0008] The drive assembly uses a drive motor to drive the lead screw to rotate. The lead screw nut is fixedly connected to the cleaning ring through a connecting plate. The connecting plate is slidably connected to the guide rod. When the lead screw rotates, the lead screw nut can drive the cleaning ring to move up and down along the length of the lead screw under the vertical guidance of the guide rod. Then, the cleaning bristles on the cleaning ring can be used to brush the inner wall of the filter cylinder, which can wash off the impurities attached to the filter screen and ensure the filtration stability of the filter cylinder.

[0009] Furthermore, an annular filter screen is embedded in the circumferential sidewall of the filter cartridge, which connects the inner cavity of the filter cartridge with the inner cavity of the filter box. Connecting seats are provided on both sides of the bottom of the filter cartridge. The bottom of the filter cartridge is open and a base plate is detachably installed. An annular sealing groove is formed on the inner wall of the bottom opening of the filter cartridge. The radius of the base plate is larger than the radius of the filter cartridge. An annular insertion part that matches the inner wall of the filter cartridge is formed on the upper surface of the base plate. A sealing ring that matches the sealing groove is fitted on the annular insertion part. Connecting blocks are formed on the base plate opposite the connecting seats. The connecting blocks and the connecting seats are connected by bolts and nuts.

[0010] The inner wall of the filter cartridge is embedded with a ring-shaped filter screen to filter the water entering the cartridge. The bottom of the filter cartridge is open and equipped with a removable base plate, which can be easily removed to clean the inside of the filter cartridge and remove the filtered impurities. The base plate and the inner wall of the filter cartridge are sealed together by a plug-in part and a sealing ring to ensure the stability of filtration. The base plate and the filter cartridge are connected by bolts, which can be easily disassembled and installed.

[0011] Furthermore, an inspection door is movably installed on the filter box, directly opposite the filter cartridge.

[0012] The filter box has a movable inspection door corresponding to the filter cartridge. The bottom plate of the filter cartridge can be removed periodically by opening the inspection door to remove the filtered impurities from the filter box, thus preventing the filter cartridge from becoming clogged.

[0013] Furthermore, a drain pipe is connected to the connection between the connecting pipe and the siphon pipe via a tee, and a normally closed valve is installed on the drain pipe.

[0014] The connection between the connecting pipe and the siphon pipe is connected to the drain pipe via a T-junction, which allows for convenient one-time water draining of the cultivation trough. This facilitates water draining and cleaning when changing the cultivation trough to other plants. Opening the normally closed valve allows for rapid emptying of the cultivation trough.

[0015] Furthermore, the inverted U-shaped top of the siphon tube is connected to a positioning air tube that extends into the cultivation trough, and a filter screen is installed at the end of the positioning air tube.

[0016] By connecting the positioning air pipe to the top of the siphon tube, the position of the positioning air pipe in the cultivation trough can be used to continuously supply water to the cultivation trough. This allows for convenient intermittent siphon drainage of the cultivation trough, enabling rapid water exchange. A filter screen is installed at the end of the positioning air pipe to facilitate filtration and prevent impurities in the trough from entering the positioning air pipe, which could cause blockage and affect the siphon effect.

[0017] The beneficial effects of this utility model are:

[0018] This invention installs a siphon pipe at the drain outlet of the cultivation trough. The water level in the cultivation trough can be set as needed, and the siphon principle enables powerless drainage. Simultaneously, a filter box is installed at the upper end of the connecting pipe. The filter cartridge within the filter box filters the drainage. The annular brush inside the filter cartridge moves up and down under the drive of a motor, brushing the annular filter screen on the inner wall of the filter cartridge. This removes impurities adhering to the filter screen, effectively ensuring the filtration effect of the filter cartridge. The filter cartridge filters impurities and fallen leaves in the water. Periodically removing impurities from the filter cartridge through the inspection door effectively prevents fallen leaves and other impurities from accumulating and rotting at the drain outlet, thus avoiding mixing with the incoming water and causing water quality degradation. This achieves powerless automatic drainage while ensuring the stability and flexibility of the drainage process. Attached Figure Description

[0025] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] Example 1:

[0027] An agronomic cultivation drainage device includes a drainage pipe installed at the drainage outlet at the bottom of the cultivation trough 1. The drainage pipe includes an L-shaped connecting pipe 2 and an inverted U-shaped siphon pipe 3 connected in sequence. The water inlet end of the connecting pipe 2 is connected to a filter box 7. The top wall of the inner cavity of the filter box 7 is connected to a filter cylinder 8. The outer top wall of the filter box 7 is embedded with a water inlet pipe 9. The lower end of the water inlet pipe 9 extends into the interior of the filter cylinder 8. A cleaning ring 13 is connected to the filter cylinder 8 through a drive assembly. A cleaning brush bristle 14 that can fit against the inner wall of the filter cylinder 8 is installed on the outer ring wall of the cleaning ring 13.

[0028] In this embodiment, the drive assembly includes a motor housing 10 installed in the center of the top wall of the filter cartridge 8, a drive motor 11 installed in the motor housing 10, a threaded rod 15 vertically connected to the output end of the drive motor 11, a nut 22 threadedly connected to the threaded rod 15, and the nut 22 and the cleaning ring 13 connected by a connecting plate 21. It also includes a smooth rod 12 vertically installed in the top wall of the filter cartridge 8 on one side of the drive motor 11, and the lower end of the smooth rod 12 passes through the connecting plate 21 and is slidably connected to the connecting plate 21.

[0029] An annular filter screen 16 is embedded in the circumferential side wall of the filter cylinder 8, which connects the inner cavity of the filter cylinder 8 with the inner cavity of the filter box 7. Connecting seats 18 are provided on both sides of the bottom of the filter cylinder 8. The bottom of the filter cylinder 8 is open and a base plate 17 is detachably installed. An annular sealing groove is formed on the inner wall of the bottom opening of the filter cylinder 8. The radius of the base plate 17 is larger than the radius of the filter cylinder 8. An annular insertion part that matches the inner wall of the filter cylinder 8 is formed on the upper surface of the base plate 17. A sealing ring 20 that matches the sealing groove is fitted on the annular insertion part. Connecting blocks are formed on the base plate 17 opposite to the connecting seats 18. The connecting blocks and the connecting seats 18 are connected by bolts and nuts 19.

[0030] To facilitate the removal of filtered impurities and fallen leaves from the filter cartridge 8, a maintenance door is movably installed on the filter box 7, directly opposite the filter cartridge 8. The inside of the filter cartridge 8 can be cleaned periodically by opening the maintenance door and disassembling the bottom plate 17 of the filter cartridge 8, thus smoothly discharging the impurities.

[0031] To facilitate the complete emptying of the water in the cultivation trough 1, a drain pipe 5 is connected to the connection between the connecting pipe 2 and the siphon pipe 3 via a tee 4. A normally closed valve 6 is installed on the drain pipe 5. The cultivation trough 1 can be quickly emptied by opening the normally closed valve 6.

[0032] The working principle of this utility model:

[0033] When the water level in the cultivation trough 1 reaches the siphon level of the siphon pipe 3, siphon drainage can be triggered. The water in the cultivation trough 1 enters the filter box 7 through the inlet pipe 9, passes through the filter cylinder 8, and the annular filter screen 16 on the filter cylinder 8 filters the inlet water. The filtered water enters the filter box 7 and enters the siphon pipe 3 through the upper end of the connecting pipe 2. It is discharged from the other end of the siphon pipe 3 by siphon action. When the liquid level in the cultivation trough 1 drops below the siphon level, the siphon drainage automatically stops, which can ensure the stability of the liquid level in the cultivation trough 1.

[0034] During filtration, impurities and fallen leaves in the cultivation trough 1 adhere to the inner wall of the annular filter screen 16 under the impact of the water inlet pipe 9. Over time, this can easily cause blockage of the annular filter screen 16. The drive motor 11 can be started periodically to drive the lead screw 15 to rotate. The lead screw nut 22 is connected to the cleaning ring 13 through the connecting plate 21. Under the sliding guide action of the smooth rod 12, the lead screw 15 can drive the lead screw nut 22 to move up and down along the length of the lead screw 15 when it rotates in both directions, thereby driving the cleaning ring 13 and the cleaning bristles. Brush 14 cleans the inner wall of the annular filter screen 16 by brushing it up and down, and washes the impurities into the filter cylinder 8. Then, the impurities and fallen leaves that have been brushed down can be removed from the filter cylinder 8 by opening the bottom plate of the filter cylinder 8 and cleaned through the maintenance door. This ensures the normal operation of the filter cylinder 8, thereby achieving the filtration and cleaning of the drainage, effectively preventing drainage blockage and removing impurities from the drainage. This prevents the impurities from accumulating at the drain outlet, rotting, and mixing with the inlet water, thus affecting the water quality.

[0035] Example 2:

[0036] Based on Example 1, this embodiment adds a positioning air pipe 23. The positioning air pipe 23 is connected to the inverted U-shaped top of the siphon pipe 3 and extends into the cultivation trough 1. A filter screen is installed at the end of the positioning air pipe 23. In this embodiment, by designing the positioning air pipe 23, an intermittent siphon effect can be achieved when water is continuously injected into the cultivation trough 1. The water in the cultivation trough 1 can be changed by using the intermittent siphon drainage, thereby improving the water quality in the cultivation trough 1.

[0037] The principle is as follows: water is continuously introduced into the cultivation tank 1, causing the water level to rise until the water level overflows at the top of the siphon pipe 3. The overflow time of the siphon pipe 3 varies depending on the amount of water introduced. Then, an automatic siphon is formed. When the water level drops to the end of the positioning air pipe 23, the siphon stops and water continues to be introduced to build up energy for the next siphon start. After water is introduced, the water level rises again and the siphon is started again. This cycle repeats. If it is necessary to completely empty the tank, the normally closed valve 6 can be opened.

[0038] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
