Description

Technical Field

[0001] This utility model relates to the field of temperature and humidity control, and in particular to a temperature and humidity control device for crop seedling greenhouses. Background Technology

[0002] Agricultural products are frequently consumed in our daily lives, and as time goes by, seasonal foods are often insufficient to satisfy our voracious appetites. Therefore, greenhouse crop seedling cultivation has emerged. By adjusting different temperatures and humidity levels, different seasonal foods can be grown. Greenhouse plants are known for their high yield, low production costs, simple cultivation methods, and high nutritional and medicinal value.

[0003] A search revealed the Chinese patent "A Temperature and Humidity Control Device for Agricultural Greenhouses" (authorization announcement number CN220915951U). The patent describes a greenhouse body with two connecting rods fixedly connected to its inner wall. These two rods are jointly connected to a mixing tank. A water inlet pipe, also fixedly connected to the mixing tank, runs through the greenhouse body. A T-shaped rod, rotatably connected to the mixing tank, runs through the mixing tank. This patent utilizes the T-shaped rod to drive the corresponding spray nozzles to rotate, thus controlling the discharge of water and gas at different temperatures and achieving temperature and humidity regulation. However, this method has the following drawbacks in practical use: while the rotating spraying method increases the spraying range, the fixed range makes it difficult to adapt to different planting areas of crop seedlings within the greenhouse, and it is also not easily compatible with greenhouses of varying sizes.

[0004] Therefore, a temperature and humidity control device for crop seedling greenhouses is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a temperature and humidity control device for crop seedling greenhouses to solve the above-mentioned problems, thereby improving the difficulty in adjusting the spraying range according to the crop planting area and the size of the greenhouse.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a temperature and humidity control device for a crop seedling greenhouse, comprising a temperature control box, a water-air dual-purpose pump disposed on its outer side, and an adjustment mechanism, wherein a set of spray pipes is disposed at the bottom of the water-air dual-purpose pump; the adjustment mechanism is used to adjust the spraying range of the spray pipes; wherein, the adjustment mechanism comprises a drive disc and a set of movable drive bars, one end of the drive bar is hinged to the inside of the drive disc, the other end of the drive bar is hinged to a slider, and the spray pipes are slidably connected to the drive bars.

[0007] Preferably, the adjustment mechanism further includes a mounting plate on which a hydraulic rod connected to the top of the drive plate is mounted, and the slider is slidably connected to the bottom of the mounting plate.

[0008] Preferably, an electric push rod is mounted on the drive bar, and one end of the electric push rod is fixedly connected to the outside of the nozzle.

[0009] Preferably, the output end of the water-air dual-purpose pump is equipped with a transfer pipe, a flexible hose passing through the mounting plate is installed between the transfer pipe and the nozzle, and the input end of the water-air dual-purpose pump is equipped with a three-way pipe communicating with the temperature control box.

[0010] Preferably, the temperature control box is equipped with a partition, and the top and bottom of the partition are provided with electric heating tubes and semiconductor cooling chips installed on the temperature control box. The heating end of the semiconductor cooling chip is located on the outside of the temperature control box, and the cooling end of the semiconductor cooling chip is located inside the temperature control box.

[0012] Preferably, the temperature control box has two through holes on one side.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting a drive disc, the drive disc can be moved up and down when adjusting the water spray range, thereby changing the tilt angle of the nozzles on the drive bar, so that a set of nozzles moves outward to adjust the spray range.

Detailed Implementation

[0020] 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.

[0021] In practical implementation: such as Figure 1-4 As shown, a temperature and humidity control device for a crop seedling greenhouse includes a temperature control box 100, a water-air dual-purpose pump 200 disposed on its outer side, and an adjustment mechanism 300. A set of spray pipes 210 is provided at the bottom of the water-air dual-purpose pump 200, and the adjustment mechanism 300 is used to adjust the spraying range of the spray pipes 210. The adjustment mechanism 300 includes a drive disk 310 and a set of movable drive bars 320. One end of the drive bar 320 is hinged to the inside of the drive disk 310, and the other end of the drive bar 320 is hinged to a slider 321. The spray pipes 210 are slidably connected to the drive bar 320.

[0022] like Figure 1 and Figure 2 As shown, the adjustment mechanism 300 also includes a mounting plate 330, on which a hydraulic rod 331 connected to the top of the drive plate 310 is mounted, and a slider 321 is slidably connected to the bottom of the mounting plate 330.

[0023] When adjusting the temperature and humidity inside the greenhouse, the user can adjust the temperature of the water source and gas inside the temperature control box 100 and then output them through the water-gas dual-purpose pump 200. This gas is then sprayed using the spray nozzle 210 to achieve the desired temperature and humidity control. When adjusting the spray range of the spray nozzle 210, the drive disc 310 can be moved downwards, driving the hydraulic rod 331 to operate and causing the drive bar 320 to change angle. At this time, the slider 321 will follow the drive bar 320 and slide adaptively on the mounting plate 330, continuously supporting the drive bar 320 and ensuring its stability. When the drive bar 320 is adjusted, the spray nozzle 210 will follow the movement, resulting in a corresponding tilt change, which alters its spray range.

[0024] like Figure 3As shown, an electric push rod 322 is mounted on the drive bar 320, and one end of the electric push rod 322 is fixedly connected to the outside of the nozzle 210.

[0025] After adjusting the tilt angle of the nozzle 210, the user can also activate the electric push rod 322 to drive the nozzle 210 to move horizontally on the drive bar 320, thereby expanding and contracting its spraying range to further achieve the effect of adjusting the spraying range. The adjustment range is wider and the usage is more diversified.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the output end of the water-air dual-purpose pump 200 is equipped with a transfer pipe 220, and a flexible hose 221 passing through the mounting plate 330 is installed between the transfer pipe 220 and the nozzle 210. The input end of the water-air dual-purpose pump 200 is equipped with a three-way pipe 230 that connects to the temperature control box 100.

[0027] The use of hose 221 facilitates the introduction of gas or water for temperature and humidity control into nozzle 210 without affecting its normal adjustment movement.

[0028] like Figure 4 As shown, a partition 110 is installed inside the temperature control box 100. Electric heating tubes 120 and semiconductor cooling chips 130 are installed on the top and bottom of the partition 110. The heating end of the semiconductor cooling chip 130 is located outside the temperature control box 100, and the cooling end of the semiconductor cooling chip 130 is located inside the temperature control box 100. The two ends of the three-way pipe 230 away from the water-air dual-purpose pump 200 are respectively located on both sides of the partition 110.

[0029] When temperature needs to be adjusted up or down, the heating element 120 and the semiconductor cooling chip 130 above the partition 110 can be used to change the temperature of the gas, which is then discharged by the water-gas dual-purpose pump 200. When humidity needs to be adjusted, the water source below the partition 110 can be discharged along the water-gas dual-purpose pump 200. In addition, when adjusting humidity, the heating element 120 and the semiconductor cooling chip 130 below the partition 110 can also be used to adjust the temperature of the water source. Temperature adjustment is carried out simultaneously during humidity adjustment, which is suitable for different usage situations.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a solenoid valve 211 is installed on the outside of the nozzle 210, and a set of nozzles 212 is installed on the outside of the nozzle 210.

[0031] The use of nozzle 212 facilitates the increase of water and air spray range, making the spraying area larger. In addition, the use of solenoid valve 211 allows users to select the corresponding spraying area according to the planting status of crop seedlings and the internal conditions of the greenhouse, making it more adaptable.

[0032] like Figure 4 As shown, two through holes 140 are provided on one side of the temperature control box 100.

[0033] External gas is introduced through the top through-hole 140, and the bottom through-hole 140 is used to connect with the external water source pipe to ensure the water source introduction effect.

[0034] Working principle: Before use, the user can install the temperature control box 100 on the outside of the greenhouse, install the water and air dual-purpose pump 200 on the inner top wall of the greenhouse, and use the mounting bracket to hoist the transfer pipe 220 and the mounting plate 330 into the greenhouse, and then carry out temperature and humidity control operations.

[0035] When regulating the temperature and humidity inside the greenhouse, water and gas can be regulated inside the temperature control box 100 and then discharged through the water-gas dual-purpose pump 200, and sprayed using the spray nozzle 210 to achieve the desired temperature and humidity control. When adjusting the spray range of the spray nozzle 210, the drive disc 310 can be moved downwards, driving the hydraulic rod 331 to operate, causing the drive bar 320 to change angle. At this time, the slider 321 will follow the drive bar 320, adaptively sliding on the mounting plate 330 to continuously support the drive bar 320 and ensure its stability. When the drive bar 320 is adjusted, the spray nozzle 210 will follow the movement, resulting in a corresponding tilt change along the drive disc 310. The 10-axis outward expansion movement changes its spraying range. After adjusting the tilt angle of the nozzle 210, the user can also activate the electric push rod 322 to drive the nozzle 210 to move horizontally on the drive bar 320, thereby expanding and contracting its spraying range to further achieve the effect of adjusting the spraying range. The adjustment range is wider and the usage is more diversified. The setting of the nozzle 212 makes it easier to increase the water and air spraying range, making the spraying range larger. In addition, the setting of the solenoid valve 211 makes it easier for users to select the corresponding spraying area according to the planting of crop seedlings and the internal conditions of the greenhouse, so as to ensure that the water and air outlet diffusion effect is more uniform and the adaptability is stronger.

[0036] It should be noted that the number of adjustment mechanisms 300 in this application can be increased according to the length of the greenhouse, so that the water-air dual-purpose pump 200 can be equipped with a corresponding number of transfer pipes 220 with valves. The specific installation and use depends on the usage requirements.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
