[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, an embodiment of the utility model provides a greenhouse for controlling temperature and humidity for crop planting, comprising a greenhouse body 1, a bracket 3 being fixed inside the greenhouse body 1, a centrifugal fan 5 being fixed on one side of the bracket 3, an air outlet of the centrifugal fan 5 being rotatably connected to a rotating tube 6, a mounting tube 7 being fixed on one side outer wall of the rotating tube 6, a circular tube 10 being fixed inside the mounting tube 7, a nozzle 11 being symmetrically distributed in the center being connected to the outer wall of one side of the circular tube 10, a driven gear 14 being fixed to the bottom outer wall of the rotating tube 6, a box body 4 being fixed on the top of the bracket 3, a rotating shaft 15 being connected to the top outer wall of the box body 4 through a bearing, a driving gear 16 being fixed on the top of the rotating shaft 15, the driving gear 16 being meshed with the driven gear 14, and a swinging mechanism being provided inside the box body 4.

[0023] Specifically, in this embodiment, it includes a greenhouse body 1, a bracket 3 is fixed inside the greenhouse body 1, a centrifugal fan 5 is fixed on one side of the bracket 3, the air outlet of the centrifugal fan 5 is rotatably connected to a rotating tube 6, the rotating tube 6 can rotate, and a mounting tube 7 is fixed to the outer wall of one side of the rotating tube 6. A circular tube 10 is fixed inside the mounting tube 7. The circular tube 10 is annular, and one side outer wall of the circular tube 10 is connected to a nozzle 11 distributed symmetrically with the center. The nozzle 11 is a humidifying atomizing nozzle in the prior art, which can spray finer droplets, which is conducive to the evaporation of water mist. A driven gear 14 is fixed to the bottom outer wall of the rotating tube 6, and a box body 4 is fixed to the top of the bracket 3. The top outer wall of the box body 4 is connected to a rotating shaft 15 through a bearing. A driving gear 16 is fixed to the top of the rotating shaft 15.

A swing mechanism is provided inside the box body 4, and the swing mechanism drives the rotating shaft 15 to swing.

[0024] The utility model provides a greenhouse with controlled temperature and humidity for crop planting, which uses a nozzle 11 to spray water mist to increase the contact area between water and air, and accelerates the water mist sprayed by the nozzle 11 through a centrifugal fan 5, so that the wind speed accelerates the evaporation of the water mist and carries the water mist to a distant place, and then drives the driving gear 16 to swing through the swing mechanism, and drives the mounting pipe 7 to swing through the driven gear 14, thereby achieving the effect of spraying water mist farther and wider when humidifying the greenhouse body 1, making the humidity control efficiency in the greenhouse body 1 higher and more uniform, which is conducive to the planting of crops inside the greenhouse body 1.

[0025] In another embodiment provided by the present invention, the inner wall of the mounting tube 7 is fixed with uniformly distributed heating wires 9, which can generate heat after being energized, so that the heat can be used to heat up the greenhouse, so that the greenhouse can maintain an appropriate temperature in winter. A retaining ring 8 is fixed inside the mounting tube 7, and the retaining ring 8 serves to isolate the heating wires 9 and the circular tube 10 to prevent water droplets on the mounting tube 7 from contacting the heating wires 9. The heating wires 9 are located on the side of the retaining ring 8 away from the circular tube 10; the swing mechanism includes a motor 20 fixed to the top of the box body 4, and the output shaft of the motor 20 extends to the inside of the box body 4 and is fixed with a turntable 17, and a connecting column 19 is fixed to the bottom outer wall of the turntable 17, and the connecting column 19 is biased towards the center of the turntable 17, and the bottom of the rotating shaft 15 is fixed to the bottom outer wall of the turntable 17. The end extends to the interior of the box body 4 and is fixed with a connecting plate 18. The bottom outer wall of the connecting plate 18 is provided with a connecting groove 23. The connecting column 19 extends to the inside of the connecting groove 23. When the turntable 17 rotates, the connecting plate 18 can be driven to swing through the connecting column 19 and the connecting groove 23, so that the connecting plate 18 drives the rotating shaft 15 to rotate back and forth. The heating wire 9 is fixed inside the mounting tube 7, so that the centrifugal fan 5 can carry out the heat generated by the heating wire 9 when working, thereby achieving the effect of controlling the heat inside the greenhouse body 1, and the driven gear 14 with a smaller diameter is driven by the larger diameter driving gear 16 to rotate, so that the amplitude of the swing driven by the driven gear 14 is increased, so that the range of the hot air heating the greenhouse is increased.

[0026] In another embodiment provided by the present invention, a filling nozzle 21 is provided on the top outer wall of the box body 4, and lubricating oil can be added to the interior of the box body 4 through the provided filling nozzle 21, so that the lubricating oil can lubricate the friction between the connecting column 19 and the connecting plate 18, thereby reducing the wear between the connecting column 19 and the connecting plate 18. A pillar 2 is fixed inside the greenhouse body 1, and the pillar 2 supports the greenhouse body. A temperature and humidity detection device 22 is fixed on one side outer wall of the pillar 2. The temperature and humidity detection device 22 is used to detect the temperature and humidity inside the greenhouse body 1, so that the staff can easily regulate the temperature and humidity inside the greenhouse body 1 according to the temperature and humidity values. A water inlet pipe 12 is fixed on the top outer wall of the box body 4, and the water inlet pipe 12 is connected to the water pump so that the water pump transports water to the inside of the water inlet pipe 12. One end of the water inlet pipe 12 is connected to a switch valve 13, and the switch valve 13 is connected to the annular pipe 10 by a hose. The hose is used to prevent interference when the installation pipe 7 moves.

[0027] Working principle: When in use, connect the water inlet pipe 12 to the outlet of the water pump through a pipe, and introduce water into the water inlet pipe 12 through the water pump, so that the water enters the inside of the circular tube 10 through pressure, and then the water is sprayed out from the nozzle 11 on one side of the circular tube from the mounting tube 7; at the same time, the centrifugal fan 5 delivers wind to the inside of the mounting tube 7 when working, and then blows wind out from the inside of the mounting tube 7, so that the wind can carry the water mist to a farther distance, and then the motor 20 drives the turntable 17 to rotate, so that the turntable 17 drives the connecting plate 18 to swing back and forth through the connecting column 19, so that the connecting plate 18 drives the driving gear 16 to move forward and backward. The reciprocating rotation causes the driving gear 16 to drive the driven gear 14 and the rotating tube 6 to rotate back and forth, thereby achieving the effect of reciprocating swing of the mounting tube 7, thereby achieving a wider range of water mist sprayed from the mounting tube 7, and improving the efficiency of humidification inside the greenhouse body 1; when it is necessary to heat the inside of the greenhouse body 1, the power supply of the heating wire 9 is turned on, and the switch valve 13 is closed, so that the wind blown out from the inside of the mounting tube 7 can carry out the heat generated by the heating wire 9, thereby achieving the effect of heating the inside of the greenhouse body 1, and the reciprocating swing of the mounting tube 7 makes the greenhouse body 1 more uniform when controlling the temperature and humidity.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
