Description

Technical Field

[0001] This utility model relates to the field of seedling bed technology, specifically a temperature-controlled seedling bed. Background Technology

[0002] A seedbed (or nursery bed) is a specialized facility used for cultivating seedlings. It provides an ideal environment for seed germination and seedling growth by controlling environmental conditions. Temperature control is a common function of seedbeds, and its purpose is to allow for setting different temperatures according to different seeds, thereby achieving the best seedling results.

[0003] However, the current temperature control methods for temperature-controlled seedling beds are relatively simple. For example, some seedling beds control the temperature of the entire seedling bed by controlling the temperature of the air around the window, while others control the temperature of the water. These temperature control methods are too simple and the temperature control effect is poor. Utility Model Content

[0027] 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.

[0028] Please see Figures 1-5 This utility model provides a technical solution:

[0029] A temperature-controlled seedling bed includes an insulated box 1 and a partition 2, as shown in the figure. The insulated box 1 is a rectangular box-shaped structure with an open top. The partition 2 is a rectangular plate-shaped structure that divides the insulated box 1 into upper and lower chambers. The top of the upper chamber is the opening of the top of the insulated box 1, while the lower chamber is filled with water to provide moisture for the seedlings. The water in the lower chamber is heated by a heating rod 7. The heating rod 7 can be heated using an electric heating principle. Electric heating is a conventional technology, and its specific model is not limited here.

[0030] Several seedling bowls 4 are all set on the horizontal partition 2, and the bottom of the seedling bowls 4 extends into the interior of the lower chamber; the horizontal partition 2 is vertically and slidably set on the inner top of the heat preservation box 1 through a driving device, and the bottom of the seedling bowls 4 can be made to contact water by lowering the height of the horizontal partition 2; the edge of the horizontal partition 2 is sealed and slidably connected to the inner wall of the heat preservation box 1 through a sealing ring; furthermore, the driving device includes a lifting rod 3 and a connecting frame 31, the lifting rod 3 is fixedly installed on the heat preservation box 1, and the connecting frame 31 is fixedly connected between the top of the lifting rod 3 and the horizontal partition 2; the lifting rod 3 can be an electric push rod, and the model of the lifting rod 3 can be the S909 from Wuxi Maiyu Transmission Technology Co., Ltd.

[0031] The lower chamber is equipped with multiple air inlet pipes 61. The blower delivers external air into the lower chamber through the air inlet pipes 61. After exchanging heat with the water in the lower chamber, the external air enters the upper chamber through several first air outlet pipes 5. The blower is not shown in the diagram. It may be an air pump with model number HBBC from Xuzhou Huayan Gas Equipment Co., Ltd.

[0032] The first air outlet pipe 5 includes a cylindrical side wall 51 and a top wall 52 fixed to the top of the side wall 51. Several air outlet holes 53 are provided on the side wall 51. The first air outlet pipe 5 can blow air with a certain temperature horizontally toward the seedlings adjacent to it through the air outlet holes 53.

[0033] Multiple sub-intake pipes 61 are fixedly connected to the main intake pipe 6. The main intake pipe 6 is located outside the insulation box 1. The blower first blows air into the main intake pipe 6, and then the air enters the multiple sub-intake pipes 61 through the main intake pipe 6.

[0034] The working principle of the above technical solution is as follows: the heating rod 7 heats the water inside the lower chamber to a suitable temperature, and then the blower delivers external air into the lower chamber through the air inlet pipe 61. This air exchanges heat with the water inside the lower chamber, and after the temperature rises, it enters the upper chamber through the first air outlet pipe 5, realizing synchronous temperature control of water and air. Since the air is heated by water, the temperature difference between the two is small, which is more conducive to seedling cultivation. When water needs to be provided to the seedlings, the lifting rod 3 is directly activated, which moves the horizontal partition 2 and the seedling bowls 4 on it downward, so that the bottom of the seedling bowls 4 comes into contact with the water. The water temperature remains constant throughout the process.

[0035] In the above scheme, by setting up a slidingly connected heat preservation box 1 and a horizontal partition 2, in conjunction with a lifting rod 3, it is convenient to provide the seedlings inside the seedling bowl 4 with a constant temperature and suitable moisture. Furthermore, the moisture in the heat preservation box 1 at a certain temperature is used to heat the air in the air inlet pipe 61, and then the air at a suitable temperature is delivered to the area around the seedlings through the first air outlet pipe 5, realizing synchronous temperature control of water and air, which is more conducive to seedling cultivation. In addition, the air through the first air outlet pipe 5 also carries a certain amount of water vapor, providing a humid environment for the growth of the seedlings.

[0036] The partition plate 2 has several through holes 21; the top of the seedling bowl 4 has an outwardly extending edge 41; the diameter of the through hole 21 is smaller than the diameter of the edge 41 and larger than the top diameter of the seedling bowl 4, so that the edge 41 can be used to block the through hole 21, and at the same time, it can prevent the seedling bowl 4 from falling into the heat preservation box 1 due to gravity.

[0037] Several second air outlets 62 are fixed to the top of the main air inlet pipe 61. The top of the second air outlets 62 are located above the water surface inside the lower chamber. "Above the water surface" means that regardless of the state of the seedling bowl 4 (which may have its bottom in contact with water or not), the top of the second air outlets 62 will always be above the water surface inside the lower chamber, thus preventing water from entering the main air inlet pipe 61. Furthermore, the air outlet at the top of the second air outlet 62 is offset from the first air outlet 5. This allows the air discharged from the second air outlet 62 to first enter the lower chamber and then be discharged through the first air outlet 5, thus carrying the moisture in the lower chamber to the upper chamber.

[0038] The intake pipe 61 includes an upper pipe 612 and a lower pipe 611 that are arranged at the top and bottom and connected to each other. The second exhaust pipe 62 is fixedly connected to the upper pipe 612. The purpose of this arrangement is to prolong the heat exchange time between air and water, ensure that the temperature of the air discharged through the second exhaust pipe 62 is basically the same as the temperature of the water, and reduce the temperature difference between water and air.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
