Description

Technical Field

[0001] This utility model relates to the field of tea seedling cultivation technology, and more specifically to an automatic irrigation seedling raising frame for tea seedlings. Background Technology

[0002] In the field of tea seedling cultivation, seedling racks are important equipment to ensure the healthy growth of tea seedlings. Among them, automatic irrigation seedling racks are widely used in large-scale tea seedling cultivation because they can provide a stable water supply for tea seedlings and reduce manual intervention.

[0003] Existing automatic irrigation seedling racks for tea seedlings typically include a frame for placing tea seedling containers, and a water storage structure on the frame for storing irrigation water, which provides the tea seedlings with the water needed for growth.

[0004] However, in actual use, the water storage structure of existing seedling racks presents many inconveniences in water changing operations. For example, the water storage area of ​​some seedling racks is tightly integrated with the rack structure, lacking a dedicated drainage channel or outlet design. When water needs to be changed, it is often necessary to manually tilt the rack or use additional tools to scoop water, which is not only cumbersome and time-consuming, but also prone to water spillage, affecting the cleanliness of the seedling environment. In addition, the water storage structure of some seedling racks is located too low or is blocked by seedling containers, which hinders both water inlet and drainage processes, making it difficult to complete water changing operations quickly and thoroughly.

[0005] The inconvenience of water exchange can lead to the water in the storage structure not being effectively renewed for a long time, which can easily breed microorganisms, accumulate impurities and salts, thereby affecting the growth environment of tea seedling roots, increasing the risk of tea seedling infection, and hindering the healthy cultivation of tea seedlings, which in turn has an adverse effect on seedling efficiency and quality. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic irrigation seedling rack for tea seedlings, which realizes automatic water replacement in the water storage tank, saves labor and time costs, and ensures a clean seedling environment.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An automatic irrigation seedling raising frame for tea seedlings includes a frame body, a clear water tank, and a return water tank. The frame body has multiple placement plates arranged from top to bottom. A water storage trough is formed on the upper surface of each placement plate. Seedling boxes are placed in the water storage trough. An installation cylinder is fixedly installed inside the water storage trough. Multiple water passage grooves are formed on the side wall of the installation cylinder. A connecting pipe is connected to the bottom of the installation cylinder. A first water pump is installed in the clear water tank. The output end of the first water pump is connected to a main water inlet pipe. Multiple water inlet branch pipes are connected to the main water inlet pipe, and each water inlet branch pipe corresponds to one of the connecting pipes. A main drainage pipe is connected to the return water tank. Multiple drainage branch pipes are connected to the main drainage pipe, and each drainage branch pipe corresponds to one of the connecting pipes. The connecting pipe, water inlet branch pipes, and drainage branch pipes are connected by a T-junction. A first solenoid valve and a second solenoid valve are respectively installed on the water inlet branch pipe and the drainage branch pipe. A return water pipe and a second water pump are connected between the clear water tank and the return water tank.

[0009] Furthermore, a filter screen is placed inside the return water tank, and the main drain pipe is located above the filter screen.

[0010] Furthermore, the bottom surface of the water storage tank is provided with multiple placement protrusions.

[0011] Furthermore, the seedling box is provided with multiple seedling troughs, and the bottom of the seedling troughs is provided with water-permeable holes.

[0012] Furthermore, a liquid level sensor is installed inside the water storage tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application constructs a complete automatic water circulation system by setting up a clear water tank and a return water tank, along with a first water pump, a second water pump, an inlet main pipe, inlet branch pipes, a drainage main pipe, drainage branch pipes, and a first solenoid valve and a second solenoid valve. This structure enables automatic water replacement in the storage tank, eliminating the need for manual emptying or scooping, significantly simplifying the water changing operation and saving labor and time costs. Simultaneously, it avoids water spillage problems that occur during manual water changing, ensuring a clean seedling environment. Furthermore, the return water pipe and the second water pump can transport water from the return water tank back to the clear water tank, achieving water resource recycling and conforming to the principles of energy conservation and environmental protection.

[0019] like Figures 1 to 3 As shown, an automatic irrigation seedling raising frame for tea seedlings includes a frame body 1, a clear water tank 2, and a return water tank 3. The frame body 1 has multiple placement plates 4 arranged from top to bottom. A water storage trough 401 is formed on the upper surface of each placement plate 4. Seedling boxes 5 are placed inside the water storage trough 401. An installation cylinder 6 is fixedly installed inside the water storage trough 401. Multiple water passages 601 are formed on the side wall of the installation cylinder 6. A connecting pipe 7 is connected to the bottom of the installation cylinder 6. A first water pump 8 is installed inside the clear water tank 2. The output end of the first water pump 8 is connected to a main water inlet pipe 9. Multiple inlet branch pipes 10 are connected to the pipe 9, and each inlet branch pipe 10 corresponds to the connecting pipe 7. A main drain pipe 11 is connected to the return water tank 3, and multiple drain branch pipes 12 are connected to the main drain pipe 11, each drain branch pipe 12 corresponding to the connecting pipe 7. The connecting pipe 7, the inlet branch pipes 10, and the drain branch pipes 12 are connected by a tee pipe 13. A first solenoid valve 14 and a second solenoid valve 15 are respectively installed on the inlet branch pipes 10 and the drain branch pipes 12. A return water pipe 16 and a second water pump 17 are connected between the clean water tank 2 and the return water tank 3.

[0020] A filter screen 18 is placed inside the return water tank 3, and the drain pipe 11 is located above the filter screen 18. This allows the old water discharged from the water storage tank 401 to be filtered by the filter screen 18 when it enters the return water tank 3, effectively removing matrix debris, impurities, etc., and purifying the water in the return water tank 3. This makes it easier for the water to be sent back to the clean water tank 2 for recycling through the return water pipe 16 and the second water pump 17, thereby improving the quality of the circulating water.

[0021] The bottom surface of the water storage tank 401 is provided with multiple placement protrusions 19; when the seedling box 5 is placed on the water storage tank 401, the placement protrusions 19 support the seedling box 5, leaving a gap between the seedling box 5 and the bottom of the water storage tank 401, which is conducive to air circulation, ensures the respiration of the tea seedling roots, and also facilitates better water circulation in the water storage tank 401.

[0022] The seedling box 5 has multiple seedling troughs 501, and the bottom of the seedling trough 501 has a water-permeable hole 502.

[0023] A liquid level sensor is installed inside the water storage tank 401.

[0024] Working principle:

[0025] When water needs to be supplied to the water storage tank 401, the first solenoid valve 14 is opened and the second solenoid valve 15 is closed. The first water pump 8 starts and sends the clean water in the clean water tank 2 into the water storage tank 401 through the main water inlet pipe 9, the branch water inlet pipe 10, the three-way pipe 13 and the connecting pipe 7 in sequence until the water level in the water storage tank 401 reaches a suitable height. After the liquid level sensor detects the corresponding water level, the first water pump 8 stops working and the first solenoid valve 14 is closed.

[0026] When it is necessary to replace the water in the water storage tank 401, close the first solenoid valve 14 and open the second solenoid valve 15. Under the action of gravity, the old water in the water storage tank 401 flows sequentially through the connecting pipe 7, the tee pipe 13, the drain branch pipe 12, and the drain main pipe 11 into the return water tank 3. After being filtered by the filter screen 18, it is retained in the return water tank 3. After the old water is drained, close the second solenoid valve 15 and open the first solenoid valve 14. The first water pump 8 starts again to send clean water into the water storage tank 401, completing the water replacement process.

[0027] In addition, when the water level in the return water tank 3 reaches a certain level, the second water pump 1 starts and transports the filtered water in the return water tank 3 back to the clean water tank 2 through the return water pipe 16, so as to realize the recycling of water resources.

[0028] This invention achieves automatic water replacement in the water storage tank 401 by constructing an automatic water circulation system, which completely solves the problem of inconvenient water replacement in existing seedling racks. It requires no manual intervention, reduces labor intensity, and improves water replacement efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
