Description

Technical Field

[0001] The utility model relates to the technical field of agricultural seedling cultivation, in particular to a seedling cultivation greenhouse with floor heating. Background Art

[0002] With the continuous development of agricultural science and technology, more and more modern agricultural technologies are being applied to crop planting, among which greenhouses are one of the most commonly used technologies. For example, in the process of sweet potato planting, sweet potato seedlings are generally grown in greenhouses. In order to increase the temperature inside the greenhouse, existing greenhouses will be equipped with floor heating to increase the temperature inside the greenhouse. Although the floor heating system can adjust the temperature according to the growth needs of different crops, it still has certain defects.

[0003] For example, in a Chinese patent with the announcement number "CN 218604245 U", a vegetable greenhouse with floor heating is disclosed. Although the device can increase the temperature inside the greenhouse, the seedlings are placed in seedling trays when they are grown, so the seedlings are at a high distance from the ground. After the floor heating pipes generate heat, more heat will be dissipated into the air. Although the temperature is increased, the heating efficiency is low. When the temperature near the seedlings reaches the standard, more thermal resources need to be wasted, which increases the cost of use. Utility Model Content

[0027] 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.

[0028] like Figure 1-Figure 8 As shown, a seedling greenhouse with floor heating includes a greenhouse body 1. A hot water conveying member for conveying hot water along a first preset channel and a cold water conveying member for conveying cold water along a second preset channel are arranged inside the greenhouse body 1. N seedling raising members 6 are detachably connected between the hot water conveying member and the cold water conveying member, N ≥ 1. A heat exchange space for exchanging heat with the outside is formed inside the seedling raising member 6, and a placement cavity for placing seedlings is formed on the seedling raising member 6, and the heat exchange space is connected to the first preset channel and the second preset channel.

[0029] Through the above technical scheme, when personnel need to grow sweet potato seedlings, the pipes for conveying hot water and the pipes for conveying cold water of the floor heating system (not shown in the figure) are connected to the hot water conveying member and the cold water conveying member respectively, and then the seedling raising member 6 is connected to the hot water conveying member and the cold water conveying member, and the hot water is discharged through the floor heating system and conveyed to the hot water conveying member, and the hot water is guided by the hot water conveying member to be conveyed to the seedling raising member 6, and then the seedling raising tray containing the sweet potato seedlings is placed in the placing cavity on the seedling raising member 6. When the hot water passes through the seedling raising member 6, the seedling raising member 6 exchanges heat with the outside world, thereby heating the vicinity of the seedling raising member 6, so that the temperature near the seedling raising member 6 is increased, so as to carry out sweet potato seedling cultivation, and the temperature of the hot water inside the seedling raising member 6 is reduced after heat exchange, and the cold water is discharged through the cold water conveying member, and the cold water is conveyed back to the floor heating system for reheating, so as to circulate. Since the distance between the seedlings and the heat source is short, the device can quickly heat up without wasting more thermal resources, thereby reducing resource consumption and improving the efficiency of temperature rise near the seedlings.

[0030] In addition, in the present invention, regarding the above-mentioned hot water conveying member and cold water conveying member:

[0031] like Figure 1-Figure 3 As shown, the hot water delivery member includes a hot water input pipe 51, and a plurality of hot water branch pipes 52 are fixedly connected to one side of the hot water input pipe 51.

[0032] The cold water delivery member includes a cold water output pipe 55, one side of which is fixedly connected to a plurality of cold water branch pipes 54, and the top of the cold water branch pipe 54 is sunken to form a plurality of water inlet heads 57 for connecting to the seedling raising member 6;

[0033] The tops of the water inlet head 57 and the water outlet head 56 are both screwed together with detachable sealing heads 53 .

When the hot water passes through the seedling raising part 6, it exchanges heat with the outside through the seedling raising part 6, thereby heating the vicinity of the seedling raising part 6, so that the temperature near the seedling raising part 6 is increased, so as to raise seedlings. After the heat exchange, the temperature of the hot water inside the seedling raising part 6 is reduced, and the cold water is transported to the cold water branch pipe 54, and the cold water is discharged through the cold water branch pipe 54, so that the cold water is transported back to the floor heating system for reheating, thereby circulating.

[0035] And in order to make the greenhouse body 1 easy to light, Figure 1 As shown, the top of the greenhouse body 1 is opened to form a light-transmitting groove 2, and a transparent blocking cloth 3 is bonded to the light-transmitting groove 2.

[0037] Through the above technical solution, when the interior of the greenhouse is heated by floor heating, the efficiency of heat dissipation from the inside of the greenhouse body 1 to the outside is reduced by the thermal insulation component 4, thereby improving the thermal insulation performance of the inside of the greenhouse body 1.

[0038] Specifically, in one embodiment, regarding the above-mentioned seedling raising part 6:

[0039] like Figure 5-Figure 8 As shown, the seedling raising member 6 includes a hot water pipe 62 for connecting to the water outlet 56 and a cold water pipe 63 for connecting to the water inlet 57;

[0040] A plurality of heat conducting plates 61 are connected between the cold water pipe 63 and the hot water pipe 62 .

Sealing rings 66 are provided inside the first flexible joint 64 and the second flexible joint 65 .

[0041] Through the above technical scheme, when personnel install the seedling raising part 6, they remove the sealing head 53 at the required position to expose the water inlet head 57 and the water outlet head 56 at the required position, and then place the hot water pipe 62 above the water outlet head 56, and place the cold water pipe 63 above the water inlet head 57, screw the first flexible joint 64 to the water outlet head 56, and screw the second flexible joint 65 to the water inlet head 57, so that the heat transfer plate 61 is connected to the hot water input pipe 51 and the cold water output pipe 55, and the hot water is output to the inside of the heat transfer plate 61 through the hot water input pipe 51 and the hot water branch pipe 52, and heat is exchanged with the outside through the heat transfer plate 61, so that the temperature near the seedling raising tray is heated, and after the temperature of the heat transfer plate 61 is reduced, the cold water is discharged through the cold water branch pipe 54 and the cold water output pipe 55, so that the cold water is transported to the floor heating system for circulation and heating, and the position and number of the seedling raising parts 6 installed can be adjusted according to personnel needs.

[0042] In addition, in the present utility model, regarding the above-mentioned thermal insulation member 4:

[0043] like Figure 4 As shown, the heat-insulating component 4 includes a heat-insulating pad 41 , and the bottom of the heat-insulating pad 41 is convex to form an anti-slip protrusion 42 .

[0044] Through the above technical solution, the heat preservation inside the greenhouse body 1 is increased by the heat preservation mat 41, and the anti-slip protrusions 42 cooperate to make the heat preservation mat 41 more stable after laying.

[0045] 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.
