Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to a greenhouse ventilation and temperature control device. Background Technology

[0002] A greenhouse is a facility used to cultivate plants. In seasons unsuitable for plant growth, it provides a growing period and increases yield. It is mostly used for the cultivation or seedling raising of warm-season plants such as vegetables, flowers, and trees during cold seasons. A plastic greenhouse is simply a plastic film and frame structure with few internal facilities and does not have the high requirements of a greenhouse. Therefore, strictly speaking, greenhouses have higher equipment requirements than plastic greenhouses.

[0003] A search revealed that patent application number CN202320906613.6 provides a greenhouse ventilation and temperature control device. This device can automatically and flexibly discharge air to achieve comprehensive and uniform temperature coverage, which is beneficial for rapidly raising the temperature of the greenhouse. However, this device has certain shortcomings. For example, the device can only discharge air evenly in all directions, while hot air rises, which can lead to insufficient temperature in the area at the bottom of the air outlet, which is not conducive to plant growth. Therefore, we propose a greenhouse ventilation and temperature control device to solve the above problems. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0022] like Figure 1-3As shown, this utility model provides a greenhouse ventilation and temperature control device, including an installation plate 1. The bottom of the installation plate 1 is connected to a support base 2, and the top is provided with a temperature control mechanism 3. The temperature control mechanism 3 includes a pole 31, a box 32, a fan 33, a heating pipe 35, an air collecting hood 36, a connecting pipe 37, and an air duct 38. The pole 31 is connected to the top of the installation plate 1, and the box 32 is connected to the top of the pole 31. The fan 33 and the heating pipe 35 are both installed inside the box 32. The left end of the connecting pipe 37 is connected to the right side of the air collecting hood 36, and the air collecting hood 36 is connected to the right side of the box 32. The rear end of the connecting pipe 37 is located inside the air duct 38 and is rotatably connected to the air duct 38. The top of the installation plate 1 is connected to a vertical plate 315. A motor 314 is installed on the left side of the vertical plate 315. The left end of the output shaft of the motor 314 is connected to the right end of the air duct 38. An air outlet 39 is provided on the air duct 38.

[0023] Specifically, by starting the fan 33 and energizing the heating tube 35 to generate heat flow, the heat flow passes through the air collector hood 36 and connecting pipe 37 and is blown into the interior of the air duct 38, and then blown out from the air outlet 39 on the air duct 38 for temperature control. During temperature control, the motor 314 is started simultaneously to drive the air duct 38 to rotate, so that the hot air is blown out evenly from different directions to achieve the purpose of full coverage, which is beneficial to the growth of plants in the greenhouse. The air duct 38 is equipped with multiple air outlets 39, which are arranged in two groups at the top and bottom of the air duct 38. Filters are installed in the air outlets 39 to prevent debris and dust from entering the air duct 38.

[0024] In this embodiment, the interior of the housing 32 is connected to a partition 34, the fan 33 is located on the left side of the partition 34, and the fan blades on the fan 33 are located on the right side of the partition 34. The heating tube 35 is located on the right side of the partition 34.

[0025] Specifically, by setting up a partition 34, the fan 33 can be separated from the heating tube 35, reducing the impact of the heating tube 35 on the fan 33. When the fan 33 starts, it drives the fan blades to rotate, thereby blowing the heat generated by the heating tube 35 into the connecting pipe 37.

[0026] In this embodiment, a rotating seat 313 is connected to the top of the mounting plate 1, and a circular shell 310 is rotatably connected to the top of the rotating seat 313. The circular shell 310 is connected to the left end of the air duct 38, and a connecting pipe 37 passes through the circular shell 310 and is rotatably connected to the circular shell 310. A bearing 311 is connected to the inner wall of the circular shell 310, and the connecting pipe 37 passes through the bearing 311. The outer wall of the connecting pipe 37 is connected to the inner ring of the bearing 311. A sealing sleeve 312 is connected to the left side of the circular shell 310, and the sealing sleeve 312 is rotatably fitted onto the connecting pipe 37.

[0027] Specifically, the top of the rotating seat 313 is provided with an arc-shaped groove, which fits against the outer wall of the round shell 310, so that the round shell 310 rotates stably with the air duct 38. By setting the round shell 310, bearing 311 and rotating seat 313, the rotation of the connection between the connecting pipe 37 and the left end of the air duct 38 is more stable. The sealing sleeve 312 is set to prevent leakage at the penetration point between the round shell 310 and the connecting pipe 37.

[0028] In this embodiment, a U-shaped plate 316 is connected to the top of the mounting plate 1, and a bearing 317 is fixedly sleeved on the outer wall of the air duct 38. The bearing 317 is installed inside the U-shaped plate 316 through a fixing rod 318.

[0029] Specifically, the bearing 317, U-shaped plate 316, and fixing rod 318 are designed to make the air duct 38 more stable when it rotates, thus providing support.

[0030] In this embodiment, a dustproof mechanism 4 is provided on the left side of the housing 32. The dustproof mechanism 4 includes a dustproof net 41. An installation hole is provided on the left side of the housing 32. The dustproof net 41 is disposed inside the installation hole. A rectangular groove 42 is provided at the top and bottom of the inner wall of the installation hole. A spring 43 is disposed inside the rectangular groove 42 and a retaining strip 44 is slidably connected thereto. The two ends of the spring 43 are respectively connected to the outer wall of the retaining strip 44 and the inner wall of the rectangular groove 42. The outer wall of the retaining strip 44 abuts against the outer wall of the dustproof net 41.

[0031] Specifically, dustproof netting 41 is installed to prevent dust and impurities from entering the housing 32 and affecting the operation of the fan 33. The rectangular groove 42, springs 43, and clamping strips 44 allow for secure installation of the dustproof netting 41 by using the upper and lower clamping strips 44. This makes installation convenient, and disassembly is easy by pulling the dustproof netting 41 to the left for cleaning. A handle (not shown in the diagram) can be installed on the outer wall of the dustproof netting 41 for easy pulling. Multiple springs 43 within the rectangular groove 42 provide sufficient clamping force for the clamping strips 44. After installation, the clamping strips 44 are embedded within the rectangular groove 42, ensuring that the dustproof netting 41 aligns with the mounting hole. The clamping strips 44 do not detach from the rectangular groove 42 after the dustproof netting 41 is removed.

[0032] It is worth noting that all the technologies not described in the above manual are existing technologies and are not the main innovations, so they will not be described in detail here.
