Description

Technical Field

[0001] The utility model belongs to the technical field of seedling raising devices, and in particular relates to a seedling raising device capable of automatically storing water. Background Art

[0002] Seedling cultivation means the cultivation of seedlings. It originally means cultivating seedlings in a nursery, hotbed or greenhouse in preparation for transplanting them into the land for planting. Irrigation is required during seedling cultivation to ensure the water needed for seedling production.

[0003] In the prior art, a Chinese patent with a reference publication number of CN 217826104 U discloses an alfalfa seedling raising device capable of automatically storing water, comprising a seedling raising box and a water pump, wherein legs are arranged at both the left and right sides and the front and rear ends of the seedling raising box, and a storage box is installed under the legs, and humidity detection components are arranged at both the left and right ends of the lower interior of the seedling raising box. The utility model can detect the water source in the storage box through a liquid level sensor, and can understand the amount of water in the storage box. When the water source is less, an alarm can be sounded through a buzzer alarm to remind the operator to add water.

[0004] The comparative document provides an alfalfa seedling raising device that can automatically store water, but the humidity sensor in the above patent is in a fixed state inside the seedling raising box. Due to the uncertainty of the flow of water in the soil, it is easy for one area to have high humidity and another area to have low humidity. This makes the detected soil moisture data inaccurate, and it is easy for water accumulation or water shortage in the soil to occur in subsequent irrigation.

[0005] Therefore, a seedling raising device which can automatically store water is proposed. Utility Model Content

[0008] Preferably, the water storage tank and the seedling raising box are both hollow rectangular parallelepiped structures with open tops.

[0009] Preferably, the probe on the soil moisture sensor can pass through the through hole.

[0010] Preferably, the other end of the ball screw is rotatably connected to an inner wall of one side of the seedling box.

[0011] Preferably, the cross section of the protective cover is a U-shaped structure.

[0012] Preferably, the irrigation rack consists of two parallel irrigation pipes and a connected irrigation pipe.

[0013] Preferably, the motor, micro electric push rod, soil moisture sensor and water pump are all electrically connected to the PLC controller.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] By moving the soil moisture sensor horizontally inside the nursery box and then raising and lowering it, multi-point humidity detection of the soil inside the nursery box can be achieved, thereby obtaining the true humidity state of the soil, ensuring the accuracy of the soil humidity detection results, avoiding the problem of uneven soil dryness and wetness in the nursery box affecting the subsequent irrigation amount, and avoiding waterlogging or lack of water in the soil causing seedling death or slow growth.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model provides a seedling raising device capable of automatically storing water, such as Figure 1-4As shown, it includes a water storage tank 1, the top of the water storage tank 1 is fixedly connected to four support columns 2 by bolts, the tops of the four support columns 2 are fixedly connected to a seedling box 3 by bolts, the water storage tank 1 and the seedling box 3 are both hollow rectangular structures with open tops, a protective cover 4 is located at the central position of the bottom of the inner part of the seedling box 3, the cross-section of the protective cover 4 is a U-shaped structure, a through hole 5 is opened on the top of the protective cover 4, a motor 6 is fixedly connected to a side position of the outer wall of one side of the seedling box 3 near the protective cover 4 by bolts, the motor 6 is fixedly connected to a ball screw 7 through its output end, the other end of the ball screw 7 is rotatably connected to the inner wall of one side of the seedling box 3, a nut seat 8 is provided on the outer wall of the ball screw 7, and the top of the nut seat 8 is fixedly connected to the inner wall of the seedling box 3 by a nut A micro electric push rod 9 is fixedly connected, and a soil moisture sensor 10 is fixedly connected to the micro electric push rod 9 through its output end. A water pump 11 is fixedly connected to the outer wall of one side of the seedling box 3 near the motor 6 through a nut. A water suction pipe 12 is fixedly connected between the input end of the water pump 11 and the water storage tank 1 through bolts. An irrigation rack 13 is fixedly connected to the output end of the water pump 11 through bolts. An irrigation hole 14 is provided at the bottom of the irrigation rack 13. A PLC controller 15 is fixedly connected to the outer wall of the seedling box 3 adjacent to the water pump 11 through bolts. The motor 6, the micro electric push rod 9, the soil moisture sensor 10 and the water pump 11 are all electrically connected to the PLC controller 15. A filter hole 16 is provided at the bottom of the seedling box 3.

[0024] It should be noted that, since the humidity sensor in the existing seedling raising device is in a fixed state inside the seedling raising box, due to the uncertainty of the flow of water in the soil, it is easy to have a problem of high humidity in one area and low humidity in another area. This makes the detected soil moisture data inaccurate, and it is easy to have problems of soil waterlogging or water shortage in subsequent irrigation. In this embodiment, the soil moisture sensor 10 is raised and lowered after horizontal movement inside the seedling raising box 3, so as to realize multi-point humidity detection of the soil inside the seedling raising box 3, thereby obtaining the true humidity state of the soil, ensuring the accuracy of the soil humidity detection results, avoiding the problem of uneven soil dryness and wetness in the seedling raising box 3 affecting the subsequent irrigation amount, and avoiding the death or slow growth of seedlings caused by soil waterlogging or water shortage.

[0025] Specifically, in this embodiment, this scheme mainly includes a protective cover 4. When in use, the soil is spread flat on the inside of the seedling box 3, water is injected into the water storage tank 1 for water storage, and seedlings are planted in the soil. Before irrigation, the motor 6 drives the ball screw 7 to rotate through its output end, and the nut seat 8 on the ball screw 7 moves horizontally, and the micro-electric push rod 9 on the nut seat 8 and the soil moisture sensor 10 move synchronously. When the nut seat 8 moves a certain distance, the motor 6 stops working, and the probe on the soil moisture sensor 10 and the through hole 5 are on the same vertical plane. At this time, the micro-electric push rod 9 drives the soil moisture sensor 10 through its output end. The soil humidity sensor 10 moves upward, and the probe on the soil moisture sensor 10 passes through the through hole 5 and is inserted into the soil. The soil humidity sensor 10 detects the humidity of the soil. Through the lateral movement of the soil humidity sensor 10 in the seedling box 3, multi-point humidity detection of the soil inside the seedling box 3 can be achieved, thereby obtaining the true humidity state of the soil. According to the lack of soil, the PLC controller 15 controls the working time of the water pump 11. The water pump 11 can draw a certain amount of water from the water storage tank 1 into the water pump 12, and irrigate and drip into the soil in the seedling box 3 under the guidance of the irrigation rack 13 and the irrigation hole 14, thereby realizing seedling irrigation.

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the probe on the soil moisture sensor 10 can pass through the through hole 5.

[0027] In this embodiment, the probe on the soil moisture sensor 10 can be inserted into the soil after passing through the protective cover 4, so as to detect the moisture in the soil.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the irrigation rack 13 is composed of two parallel irrigation pipes and a connected irrigation pipe.

[0029] In this embodiment, water can be evenly irrigated and dripped into the seedling box 3, thereby ensuring that the soil in the seedling box 3 is evenly irrigated.
