Description
Technical Field
[0001] The utility model relates to the technical field of crop planting, in particular to a temperature-insulating and humidity-controlling seedling raising device. Background Art
[0002] Seedling cultivation refers to the cultivation of seedlings in a nursery, hotbed or greenhouse in preparation for transplanting to the land for planting. Wet seedling cultivation is to sow the coated seeds directly into the seedling tray filled with substrate in a greenhouse or greenhouse. The seedling tray is in a seedling pool. Before the tobacco seedlings are sealed, the nutrients and water required for seed germination and seedlings are supplied by the nutrient solution at the bottom of the pool (1-2 cm deep) through the capillary action of the substrate. After the tobacco seedlings are sealed, the required water and nutrients are supplied by artificial spraying on the tray surface, and the dry and wet alternation is maintained. Wet seedling cultivation is an agricultural planting technology mostly used for green leafy vegetables, tobacco and other plants with a short growth period. It can ensure the consistency of plant growth and avoid soil pests and diseases caused by traditional cultivation methods. It is widely used in greenhouse cultivation around the world. In the wet seedling cultivation process, a seedling pool is usually used as a seedling raising device.
[0003] The patent with the announcement number CN219125023U discloses an automatic temperature-control and water-control floating seedling system, including a waterproof pool membrane, the waterproof pool membrane is arranged in a seedling water tank, a heating pad is attached under the waterproof pool membrane, a timer switch is installed on the heating pad, and an automatic water-adding device is connected to the top of the waterproof pool membrane through a water pipe. The automatic water-adding device includes a water level control device, a water tank, and a water pump, and the heating pad and the automatic water-adding device are connected to a power supply. The automatic temperature-control and water-control floating seedling system automatically adds water by setting an automatic water-adding device to prevent the seedlings from being drought-stricken. In actual use, the seedling system can only add water when the water level in the waterproof pool membrane is low. When the water level in the waterproof pool membrane is high, the drainage operation is inconvenient and the water level cannot be quickly lowered, which easily causes a high humidity in the seedling pool, affecting the seedling cultivation. Utility Model Content

[0005] The technical solution of the utility model is achieved in this way:
[0006] A temperature-insulating and humidity-controlling seedling raising device comprises a seedling raising pool, a temperature-insulating component is provided at the bottom of the seedling raising pool, and a humidity-control component for controlling the water level in the seedling raising pool is provided on the side of the seedling raising pool. The temperature-insulating component can reduce the temperature loss at the bottom of the seedling raising pool to ensure the seedling raising temperature, and the humidity-control component can control the water level in the seedling raising pool. When the water level in the seedling raising pool exceeds the set height, the water in the seedling raising pool is automatically discharged to avoid excessive humidity.
[0007] The humidity control assembly includes a baffle, which is slidably connected to the side wall of the seedling pool, slides in a vertical direction, is provided with a through hole, and a side water outlet hole is provided on the side of the seedling pool, and the through hole corresponds to the side water outlet hole.

[0008] The side wall of the seedling raising pool is provided with a plurality of vertically arranged limit bars, and the baffle is located between the limit bars and the side wall of the seedling raising pool. The limit bars limit the baffle in the horizontal direction to prevent the baffle from being separated from the seedling raising pool, and the baffle can move up and down inside the limit bars.
[0009] The limit bar is threadedly connected with a locking bolt, which passes through the limit bar and is pressed and matched with the baffle. After the baffle is moved into place, the locking bolt is tightened so that the locking bolt presses the baffle to fix the baffle and keep the baffle stable during use.
[0010] The side water outlet holes are long strip holes, and the long strip holes are arranged vertically. During the up and down movement of the baffle plate, the through holes on the baffle plate are always connected with the side water outlet holes.
[0011] A sealing ring is arranged between the baffle plate and the side wall of the nursery pool, and the side water outlet is located inside the sealing ring. The sealing ring ensures the sealing between the baffle plate and the side wall of the nursery pool, and prevents water from seeping out from the gap between the baffle plate and the side wall of the nursery pool.
[0012] The side wall of the seedling raising pool is provided with scale lines, and the upper edge of the baffle corresponds to the scale lines. The height of the through hole can be determined by checking the corresponding position of the upper edge of the baffle and the scale lines, and then the water level in the seedling raising pool can be determined.
[0013] The heat preservation component is a hollow interlayer arranged at the bottom of the nursery pool. The hollow interlayer can reduce the heat transfer efficiency, thereby reducing the temperature loss at the bottom of the nursery pool.
[0014] The bottom of the seedling raising pool is provided with a drainage hole, and a plug is detachably connected to the drainage hole. After the seedling raising pool is used, the plug is removed, and the water in the seedling raising pool can be completely discharged from the drainage hole, which is convenient for cleaning the seedling raising pool.
[0015] The seedling pool is provided with a plurality of seedling trays, and the side length of the seedling pool is an integral multiple of the side length of the seedling tray. The seedling tray is adapted to the size of the seedling pool, so that there is no extra space in the seedling pool after the seedling tray is placed, the evaporation of water in the seedling pool is reduced, the humidity in the seedling pool is easily ensured, and the exposure of the inside of the seedling pool is reduced to prevent the growth of moss.
[0016] The beneficial effects of the utility model are as follows: the heat preservation component can reduce the temperature loss at the bottom of the nursery pool to ensure the nursery temperature, and the humidity control component can realize the control of the water level in the nursery pool. When the water level in the nursery pool exceeds the set height, the water in the nursery pool is automatically discharged to avoid excessive humidity, thereby realizing true wet nursery. By sliding the baffle up and down on the nursery pool, the height of the through hole is changed, and the relative position of the through hole and the side water outlet hole is changed, thereby realizing the adjustment of the water outlet height of the nursery pool.
[0017] After the baffle is moved into place, tighten the locking bolts so that the locking bolts press the baffles tightly to fix the baffles and keep the baffles stable during use. After the nursery pool is used, remove the plug and drain all the water in the nursery pool from the drainage hole, which is convenient for cleaning the nursery pool.
[0018] The size of the seedling tray is adapted to the size of the seedling pool, so that there is no extra space after the seedling tray is placed in the seedling pool, reducing the evaporation of water in the seedling pool, making it easy to ensure the humidity in the seedling pool, and at the same time reducing the exposure of the inside of the seedling pool to prevent moss growth.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1, as Figure 1 , Figure 2 As shown, a temperature-insulating and humidity-controlling seedling raising device comprises a seedling raising pool 1, a temperature-insulating component is provided at the bottom of the seedling raising pool 1, and a humidity-control component 3 for controlling the water level in the seedling raising pool 1 is provided on the side of the seedling raising pool 1. The temperature-insulating component can reduce the temperature loss at the bottom of the seedling raising pool 1 to ensure the seedling raising temperature, and the humidity-control component 3 can control the water level in the seedling raising pool 1. When the water level in the seedling raising pool 1 exceeds the set height, the water in the seedling raising pool 1 is automatically discharged to avoid excessive humidity.
[0027] Furthermore, a plurality of seedling trays 2 are provided in the seedling pool 1, and the side length of the seedling pool 1 is an integer multiple of the side length of the seedling tray 2. Figure 1 As shown, in the present embodiment, four seedling raising trays 2 are arranged in the seedling raising pool 1, and the seedling raising trays 2 are adapted to the size of the seedling raising pool 1. After the seedling raising trays 2 are placed in the seedling raising pool 1, there is no redundant space in the seedling raising pool 1, which reduces the evaporation of water in the seedling raising pool 1, makes it easy to ensure the humidity in the seedling raising pool 1, and reduces the exposure of the interior of the seedling raising pool 1 to prevent the growth of moss.
[0028] Embodiment 2, based on embodiment 1, a temperature-keeping and humidity-controlling seedling raising device, such as Figure 3 , Figure 4 As shown, the humidity control component 3 includes a baffle 31, which is slidably connected to the side wall of the seedling pool 1, and slides in the vertical direction. A through hole 33 is provided on the baffle 31, and a side water outlet 11 is provided on the side of the seedling pool 1, and the through hole 33 corresponds to the side water outlet 11. In this embodiment, the baffle 31 is located outside the seedling pool 1, and the baffle 31 slides up and down to adjust the height of the through hole 33, and at the same time change the relative position of the through hole 33 and the side water outlet 11, thereby realizing the adjustment of the water outlet height of the seedling pool 1. Specifically, the height of the through hole 33 is the water level height in the seedling pool 1. When the amount of water in the seedling pool 1 is large and the water level is higher than the height of the through hole 33, the water in the seedling pool 1 is automatically discharged from the through hole 33 to avoid excessive water and affect the humidity of the seedlings. In addition, water can be continuously poured into the nursery pool 1 during the seedling raising process. When the water level in the nursery pool 1 is lower than the through hole 33, water is poured to supplement the water. When too much water is poured, the water in the nursery pool 1 is directly discharged from the through hole 33 to avoid the water level being too high. The operation process is simple and convenient.
[0029] Furthermore, a plurality of vertically arranged limiting strips 32 are provided on the side wall of the seedling raising pool 1, and the baffle 31 is located between the limiting strips 32 and the side wall of the seedling raising pool 1. Figure 4 As shown, in this embodiment, two limit bars 32 are provided on the side wall of the seedling pool 1, and the two ends of the limit bars 32 are connected to the side wall of the seedling pool 1 by screws. The limit bars 32 can limit the horizontal direction of the baffle 31, so that the baffle 31 can only move up and down. The limit bars 32 are threadedly connected with locking bolts, which pass through the limit bars 32 and are pressed and matched with the baffle 31. After the baffle 31 is moved into place, the locking bolts are tightened so that the locking bolts press the baffle 31, thereby fixing the baffle 31 and keeping the baffle 31 stable during use.
[0030] Furthermore, the side water outlet holes 11 are long holes, and the long holes are arranged vertically. The long holes correspond to the through holes 33. When the baffle plate 31 moves up and down, the through holes 33 on the baffle plate 31 are always connected with the side water outlet holes 11, so as to avoid the situation that the side water outlet holes 11 and the through holes 33 are misaligned and cause the through holes 33 to be blocked.
[0031] Furthermore, a sealing ring 34 is provided between the baffle 31 and the side wall of the nursery pool 1, and the side water outlet 11 is located inside the sealing ring 34. The sealing ring 34 ensures the sealing between the baffle 31 and the side wall of the nursery pool 1, and prevents water from seeping out from the gap between the baffle 31 and the side wall of the nursery pool 1.
[0032] Furthermore, the side wall of the nursery pool 1 is provided with a scale line 13, and the upper edge of the baffle 31 corresponds to the scale line 13. By checking the corresponding position of the upper edge of the baffle 31 and the scale line 13, the height of the through hole 33 can be determined, and then the water level in the nursery pool can be determined, which is convenient for controlling the water level in the nursery pool 1.
[0033] Embodiment 3, based on embodiment 1 or 2, the heat preservation component is a hollow interlayer 12 arranged at the bottom of the nursery pool 1. The hollow interlayer 12 can reduce the heat transfer efficiency, thereby reducing the temperature loss at the bottom of the nursery pool 1, and achieving the heat preservation of the nursery pool 1.
[0034] Further, a drainage hole is provided at the bottom of the nursery pool 1, and a plug 4 is detachably connected to the drainage hole. After the nursery pool 1 is used, the plug 4 is removed, and the water in the nursery pool 1 can be completely discharged from the drainage hole, which is convenient for cleaning the nursery pool 1.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
