Description

Technical Field

[0001] This utility model relates to the field of seedling raising device technology, and in particular to a water-saving and drought-resistant seedling raising device. Background Technology

[0002] Seedling raising refers to the process of cultivating plant seedlings under controlled conditions. This is an important technical measure in agricultural production, and seedling raising simply means cultivating seedlings. Originally, it referred to cultivating seedlings in nurseries, hotbeds, or greenhouses in preparation for transplanting them into the ground.

[0003] For example, Chinese utility model patent application number 202321561339.X discloses a water-saving irrigation device for plant seedling cultivation, specifically relating to the field of irrigation technology. It includes a support frame, a water storage tank fixedly connected to one side of the support frame, and an extraction pipe penetrating through the inner wall of the water storage tank. A water pump is installed at the other end of the extraction pipe, and a spray pipe is penetrating through the other end of the delivery pipe. A fixing frame is fixedly connected to the outer wall of the support frame, and a motor is installed above the fixing frame. The output shaft of the motor is connected to a transmission rod via a coupling. This water-saving irrigation device for plant seedling cultivation, through its spray nozzles, fixing rod, and cultivation box, facilitates uniform irrigation of plant seedlings by workers, thereby reducing the cost of irrigation and preventing uneven irrigation that could affect plant growth. This ensures the stability of the overall device in irrigating plant seedlings.

[0004] The aforementioned patent filters and recycles excess water after irrigation. However, since the filter plate can only perform simple filtration, the filtered water still contains a large number of small particulate impurities, making the water turbid and easily polluting the clear water in the reservoir. When the turbid water is used to irrigate seedlings, the impurities are adsorbed onto the seedling leaves. The impurities in the turbid water adhere to the leaf surface, blocking the leaf stomata and affecting the plant's gas exchange (such as carbon dioxide absorption and oxygen release). In the long term, this may lead to a decrease in photosynthetic efficiency and affect the growth and development of seedlings.

[0005] Therefore, it is necessary to provide a water-saving and drought-resistant seedling raising device to solve the above-mentioned technical problems. Summary of the Invention

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1-7The present invention provides a water-saving and drought-resistant seedling raising device, comprising a water storage tank 1, the inner cavity of which is divided into a clear water chamber 3 and a turbid water chamber 4 by a partition 2, a support frame 5 fixedly installed at each of the four corners of the top of the water storage tank 1, a plurality of water collection trays 6 fixedly installed between the four support frames 5, a turbid water return mechanism 7 provided between the plurality of water collection trays 6 and the turbid water chamber 4, a drive mechanism 8 and a water supply mechanism 9 fixedly installed on the back of the water storage tank 1, a vertical frame 10 fixedly installed on the drive mechanism 8, and a clear water irrigation mechanism 11 and a turbid water irrigation mechanism 12 respectively provided on the left and right sides of the vertical frame 10.

[0035] The water collection tray 6 is connected to a seedling tray 13, which has two rows of seedling chambers 14 inside. A filter plate 15 is fixedly connected to the bottom of the seedling tray 13.

[0036] The drive mechanism 8 includes two mounting brackets 801 fixedly installed on the back of the water storage tank 1. A servo motor 802 is fixedly installed on one of the mounting brackets 801. A threaded rod 803 is fixedly connected to the output end of the servo motor 802. A threaded block 804 is threadedly connected to the outer surface of the threaded rod 803. Guide rods 805 are movably inserted inside the threaded block 804 and located on the upper and lower sides of the threaded rod 803. The guide rods 805 are fixedly connected to the mounting bracket 801. The vertical frame 10 is fixedly installed on the back of the threaded block 804. The output end of the servo motor 802 rotates clockwise or counterclockwise, driving the threaded rod 803 to rotate. Under the limiting action of the guide rod 805 on the threaded block 804, the threaded block 804 moves to the left or right along the axis of the threaded rod 803, thereby driving the vertical frame 10, the clear water irrigation mechanism 11 and the muddy water irrigation mechanism 12 to move synchronously, so that the clear water irrigation mechanism 11 and the muddy water irrigation mechanism 12 can evenly irrigate the seedlings in the seedling tray 13.

[0037] The water irrigation mechanism 11 includes a water supply pipe 1101 fixedly installed on one side of the vertical frame 10. Multiple irrigation pipes 1102 are fixedly connected to the water supply pipe 1101. Several water outlets 1103 are opened at the bottom of the irrigation pipes 1102. The number of irrigation pipes 1102 and irrigation pipes 1202 is the same as the number of seedling trays 13. Each seedling tray 13 is equipped with irrigation pipes 1102 and irrigation pipes 1202. Through the cooperation of the water irrigation mechanism 11 and the water supply mechanism 9, the water is used to water the entire seedlings in the seedling trays 13.

[0038] The turbid water irrigation mechanism 12 includes a water supply hard pipe 1201 fixedly installed on one side of the vertical frame 10. Several irrigation pipes 1202 are fixedly connected to the water supply hard pipe 1201. Two watering pipes 1203 are fixedly connected to the other end of the irrigation pipes 1202. The two watering pipes 1203 are inclined and face the two rows of seedling chambers 14 on the seedling tray 13 respectively. The end of the irrigation pipe 1202 away from the water supply hard pipe 1201 extends to the middle of the seedling tray 13 and the distance between it and the seedling tray 13 is 3-5 cm. Through the cooperation of the turbid water irrigation mechanism 12 and the water supply mechanism 9, it is used to directionally water the cultivation substrate in the seedling tray 13, that is, to directionally replenish the water to the plant roots. This realizes the utilization of recycled turbid water, avoids the waste of water resources, and avoids the use of turbid water to water the plant leaves, which would cause impurities in the turbid water to block the leaf stomata.

[0039] The water supply mechanism 9 includes a water pump 901 fixedly installed on the back of the water storage tank 1. The pumping end of the water pump 901 is fixedly connected to a Y-shaped pipe 902. The two ends of the Y-shaped pipe 902 away from the water pump 901 are respectively connected to the clear water chamber 3 and the turbid water chamber 4. A solenoid valve 903 is installed at the end of the Y-shaped pipe 902 near the clear water chamber 3, and a solenoid valve 904 is installed at the end of the Y-shaped pipe 902 near the turbid water chamber 4. The water outlet end of the water pump 901 is fixedly connected to a water supply hose 905. The other end of the water supply hose 905 is fixedly connected to a Y-shaped pipe 906. A solenoid valve 907 is fixedly installed at the end of the Y-shaped pipe 906 near the water supply hard pipe 1101, and a solenoid valve 908 is fixedly installed at the end of the Y-shaped pipe 906 near the water supply hard pipe 1201.

[0040] The turbid water return mechanism 7 includes a return main pipe 701, which is connected to the turbid water chamber 4. Multiple return branch pipes 702 are fixedly connected to the return main pipe 701. The number of return branch pipes 702 is the same as the number of water collection trays 6 and their positions are set in a one-to-one correspondence. The return branch pipes 702 are connected to the bottom of the water collection trays 6.

[0041] A battery 16 and a control panel 17 are provided on one side of the water storage tank 1. The front of the battery 16 is provided with two water inlets 18, which are connected to the clear water chamber 3 and the turbid water chamber 4 respectively. Solenoid valve 1 903, solenoid valve 2 904, solenoid valve 3 907, solenoid valve 4 908, water pump 901 and servo motor 802 are all electrically connected to the battery 16 through the control panel 17. In the initial state, water pump 901, servo motor 802, solenoid valve 1 903, solenoid valve 2 904, solenoid valve 3 907 and solenoid valve 4 908 are all in the closed state.

[0042] Working principle: First, the staff cultivates and plants the seedlings in the seedling cavity 14 of the seedling tray 13. The filter plate 15 set at the bottom of the seedling tray 13 filters and intercepts large particles of seedling substrate to prevent them from entering the pipeline and causing blockage. Then, an appropriate amount of clean water is injected into the clear water cavity 3 and the turbid water cavity 4 from the water inlet 18 for later use.

[0043] When it is necessary to water the leaves of the plants cultivated in the seedling tray 13, the solenoid valve 903, solenoid valve 907, water pump 901 and servo motor 802 are activated through the control panel 17. The water pump 901 uses the Y-shaped pipe 902 to draw water stored in the clear water chamber 3 and delivers it to the irrigation pipe 1102 through the water supply hose 905, the Y-shaped pipe 906 and the water supply hard pipe 1101 in sequence. Then it flows out downward through the blow nozzle. At the same time, the output end of the servo motor 802 rotates clockwise or counterclockwise, driving the threaded rod 803 to rotate. Under the limiting action of the guide rod 805 on the threaded block 804, the threaded block 804 moves to the left or right along the axis of the threaded rod 803, thereby driving the vertical frame 10, the clear water irrigation mechanism 11 and the muddy water irrigation mechanism 12 to move synchronously, so as to achieve uniform irrigation of the seedlings in the seedling tray 13.

[0044] After watering, excess water in the seedling tray 13 drips into the water collection tray 6, and then flows back into the turbid water chamber 4 through the return branch pipe 702 and the return main pipe 701 in sequence, so as to achieve separate collection of excess water.

[0045] When it is necessary to water the roots of the seedlings in the seedling tray 13, the control panel 17 is used to open the solenoid valve 904, solenoid valve 908, water pump 901 and drive mechanism 8. The water pump 901 uses the Y-shaped pipe 902 to draw the turbid water stored in the turbid water chamber 4 and delivers it to the irrigation pipe 1202 through the water supply hose 905, the Y-shaped pipe 906 and the water supply hard pipe 1201. Then, the turbid water is poured directly onto the seedling substrate through the irrigation pipe 1203, so as to achieve directional watering of the roots of the seedlings. This avoids the turbid water passing through the leaves of the plants, which would cause the leaf surface to absorb a large number of impurities and block the stomata. This is conducive to the photosynthesis and growth and development of the seedlings. In addition, watering the seedlings can also help with drought resistance.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
