DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Example

[0025] like Figure 1-4 As shown, a greenhouse heating device includes a frame 1, the inner bottom end of the frame 1 is fixedly connected to a motor 2, the output end of the motor 2 is fixedly connected to a shaft rod 3, the upper end of the shaft rod 3 is fixedly connected to a mounting seat 31, the upper end of the mounting seat 31 is rotatably connected to an air outlet tube 4, the upper end of the frame 1 is fixedly connected to a special-shaped guide rail 5, the upper end of the special-shaped guide rail 5 is in contact with the outer circumferential surface of the air outlet tube 4, the outer circumferential surface of the special-shaped guide rail 5 is fixedly connected to a mounting frame 6, one end of the mounting frame 6 is fixedly connected to a hot air blower 7, one side of the hot air blower 7 is fixedly connected to an air collecting hood 8, one side of the air collecting hood 8 is fixedly connected to a hose 9, and one end of the hose 9 is rotatably connected to the air outlet tube 4.

[0026] When in use, for a larger greenhouse, first place the entire device in the center of the greenhouse. After starting the hot air blower 7, the hot air flow output by the hot air blower 7 will enter the air outlet 4 through the air collecting hood 8 and the hose 9, and then blow to the outside, so as to heat the greenhouse. When the hot air blower 7 is turned on, the motor 2 is also turned on synchronously. The motor 2 cooperates with the shaft 3 to drive the air outlet 4 to rotate 360°. At the same time, the rotating air outlet 4 will swing up and down synchronously under the guidance of the special-shaped guide rail 5, so that the hot air flow output from the air outlet 4 can be actively blown to various areas in the entire greenhouse, greatly improving the heating effect.

[0027] The hot air blower 7 has an electric heating tube and a fan therein. The hot air blower 7 belongs to the existing known technology, and the specific principle of how to produce hot air will not be described in detail.

[0028] like Figure 1-2 As shown, one end of the hose 9 is fixedly connected to a connecting tube 91, the outer circumferential surface of the connecting tube 91 is fixedly connected to a sealing bearing 92, the outer circumferential surface of the air outlet tube 4 is fixedly connected to a connecting tube 43, the central axis of the connecting tube 43 is consistent with the central axis of the shaft 3, and the connecting tube 43 is fixed to the outer circumferential surface of the sealing bearing 92.

[0029] When in use, the air outlet tube 4 and the hot air blower 7 are connected by the hose 9. When the air outlet tube 4 swings up and down, the air outlet tube 4 is not limited by the hose 9, ensuring that the air outlet tube 4 can swing up and down. Under the connection of the sealed bearing 92, the hose 9 will not be entangled when the air outlet tube 4 rotates.

[0030] like Figure 1-3 As shown, the outer circumference of the air outlet cylinder 4 is fixedly connected to the second mounting seat 41 , the inner wall of the second mounting seat 41 is rotatably connected to the roller 42 , and the upper end of the special-shaped guide rail 5 is provided with a rubber layer 51 , which contacts the outer circumference of the roller 42 .

[0031] During use, when the air outlet tube 4 rotates along the upper end of the special-shaped guide rail 5 , the roller 42 is in contact with the rubber layer 51 , and the roller 42 can rotate under the friction resistance of the rubber layer 51 , thereby reducing the wear on the rubber layer 51 .

[0032] like Figure 1 and 4 As shown, the rubber layer 51 matches the shape of the upper end of the special-shaped guide rail 5 , and the rubber layer 51 is specifically embedded in the upper end of the special-shaped guide rail 5 .

[0033] During use, when the rubber layer 51 is damaged, it is convenient to disassemble and replace the rubber layer 51 .

[0034] In summary, the specific working process of this scheme is as follows: when targeting a larger greenhouse, first place the entire device in the center of the greenhouse. After starting the hot air blower 7, the hot air flow output by the hot air blower 7 will enter the air outlet 4 through the wind collecting hood 8 and the hose 9, and then blow to the outside, thereby heating the greenhouse. When the hot air blower 7 is turned on, the motor 2 is also turned on synchronously. The motor 2 cooperates with the shaft 3 to drive the air outlet 4 to rotate 360°. At the same time, the rotating air outlet 4 will swing up and down synchronously under the guidance of the special-shaped guide rail 5, so that the hot air flow output from the air outlet 4 can be actively blown to various areas in the entire greenhouse, greatly improving the heating effect.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
