Traditional greenhouses have a lot of daily operations. In summer, the sunshine intensity is relatively large and the temperature in the greenhouse rises relatively quickly. At this time, in order to keep the temperature in the greenhouse constant, the greenhouse needs to be ventilated and heat-dissipated.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] Example 1

[0026] In this embodiment, the blower motor 27 is fixed inside the blower structure 2 by the cooperation of the blower housing 25 and the cross bar 26. When the blower motor 27 rotates, suction is generated to absorb external air through the air inlet 21. The protective net 23 prevents debris in the air from being sucked in. The air inlet neck 24 can prevent rain while preventing birds from building nests inside it. The air inlet neck 24 is fixed inside the top surface of the greenhouse 1 and acts as a gas conveying conduit. The air duct 22 conveys the absorbed gas to the inside of the wind direction adjusting device 29, and the wind direction adjusting device 29 discharges the gas.

[0028] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the wind direction adjusting device 29 includes an air outlet housing 291, the input end of the air outlet housing 291 is fixedly connected to the output end of the air guide 22, the inner side of the air outlet housing 291 is fixedly connected with a spring rod 299, the output end of the spring rod 299 is fixedly connected with a clamping plate 2910, the side of the clamping plate 2910 is fixedly connected with a pull rod 2911, the inner side of the air outlet housing 291 is fixedly connected with a fixing rod 292, the inside of the fixing rod 292 is fixedly connected with a bearing 293, the inside of the bearing 293 is fixedly connected with a rotating rod 294, the side of the rotating rod 294 is fixedly connected with a wind shield 295, the side of the wind shield 295 is fixedly connected with a control rod 296, the side of the control rod 296 is movably connected with a connecting rod 297, the bottom surface of the connecting rod 297 is fixedly connected with a power rod 298, and the power rod 298 is movably connected in a slide groove opened on the inner bottom surface of the air outlet housing 291.

[0029] In this embodiment, gas can flow inside the air outlet housing 291, and stepping on the power rod 298 causes the connecting rod 297 to drive the control rod 296 to deflect downward. The side of the wind shield 295 fixedly connected to the control rod 296 is fixedly connected with a rotating rod 294, and the rotating rod 294 is fixed in the bearing 293, so that when the wind shield 295 is driven by the connecting rod 297, it can only rotate around the bearing 293 as the axis to guide the wind direction. The splint 2910 limits the power rod 298 under the action of the pull rod 2911. When the wind direction needs to be adjusted, it can be adjusted by pulling up the pull rod 2911.

[0030] Example 3

[0031] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the ventilation mechanism 3 includes an air outlet 31, the air outlet 31 is fixedly connected to the other end of the top surface of the greenhouse 1, the top surface of the air outlet 31 is fixedly connected with an air guide cap 32, the bottom surface of the air outlet 31 is fixedly connected with an air outlet neck 33, one end of the air outlet neck 33 passes through the inside of the top surface of the greenhouse 1 and is fixedly connected with an air blowing shell 34, the inner bottom end of the air blowing shell 34 is fixedly connected with a cross bar 37, the middle part of the top surface of the cross bar 37 is fixedly connected with an air outlet motor 38, and the air outlet motor The output shaft of 38 is fixedly connected to the fan blade 2 39, the bottom end of the blowing shell 34 is fixedly connected to the air outlet pipe 35, the bottom surface of the air outlet pipe 35 is fixedly connected to the air outlet device 36, the air outlet device 36 includes an output port 362, the output port 362 is fixedly connected to the input end of the air outlet pipe 35, the outer surface of the output port 362 is fixedly connected to the air intake shell 361, the side of the air intake shell 361 is movably connected to the filter shell 363, the interior of the filter shell 363 is fixedly connected to the filter 364, and the side of the filter shell 363 is fixedly connected to the handle 365.

[0032] In this embodiment, the suction force generated by the fan blades 39 driven by the air outlet motor 38 absorbs the air in the greenhouse 1 through the air outlet device 36. Since the hot air is generally located above the cold air, and there is a blower mechanism 2 at the bottom of the greenhouse 1 for blowing air, the air outlet device 36 can absorb most of the air inside the greenhouse 1, and cooperate with the blower mechanism 2 to circulate the air and discharge the indoor air through the air guide cap 32. The air guide cap 32 can guide the exhaust gas to the outside of the ventilation mechanism 3 to prevent the exhaust gas from flowing back. The filter 364 will filter the absorbed indoor air to prevent clogging the ventilation mechanism 3. When the ventilation efficiency of the filter 364 is poor, the filter housing 363 can be replaced by a new filter housing 363 by removing the filter housing 363 through the handle 365.

[0033] The following is a detailed description of the working principle of the agricultural circulating ventilation greenhouse.

[0034] like Figure 1-5As shown, the fan blade 28 is driven by the blower motor 27 to absorb external air. The external air enters the interior of the blower mechanism 2 from the inside of the air inlet 21, and is transported to the inside of the wind direction adjustment device 29 through the air duct 22. The power rod 298 is moved to make the connecting rod 297 drive the control rod 296 to move. Since the side of the wind shield 295 is fixed inside the bearing 293, the wind shield 295 can only rotate around the bearing 293 as the axis under the drive of the connecting rod 297. The inclination angle of the wind shield 295 can be adjusted by adjusting the height of the power rod 298 to adjust the wind direction. The air outlet motor 38 drives the fan blade 2 39 to rotate, absorbs indoor air from the inside of the air outlet device 36, and discharges it through the air outlet 31. The air guide cap 32 will guide the air for easy discharge. When the ventilation performance of the filter 364 is poor, the filter housing 363 can be pulled out by grasping the handle 365 to replace the new filter 364.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
