DETAILED DESCRIPTION

[0025] The embodiment of the utility model provides a greenhouse internal ventilation device for smart agriculture.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A smart agricultural greenhouse internal ventilation device comprises an outer shell 1 and a ventilation pipe 2 installed at one end of the outer shell 1, a plurality of ventilation holes 21 are provided on the ventilation pipe 2, one end of the ventilation pipe 2 is fixedly connected with a mounting plate 22, the mounting plate 22 is detachably connected to one end of the outer shell 1 by bolts, one end of the outer shell 1 is fixedly connected with a filter screen cylinder 3 connected to the outer shell 1, the interior of the outer shell 1 is fixedly connected with a fixing frame 4, an air induction mechanism is installed on the fixing frame 4, the outside air is sucked into the interior of the outer shell 1 through the air induction mechanism inside the outer shell 1, and then is evenly filled into the interior of the greenhouse through the ventilation holes 21 on the ventilation pipe 2, so as to ventilate the greenhouse. The interior of the shed is ventilated. By removing the bolts on the mounting plate 22, ventilation pipes 2 of different lengths can be selected according to the size of the shed. The air induction mechanism includes a rotating rod 41 rotating on a fixing frame 4, and one end of the rotating rod 41 is fixedly connected to a fan 42. The interior of the outer shell 1 is fixedly connected to a driving motor 43 for driving the rotating rod 41 to rotate. By starting the driving motor 43 to drive the rotating rod 41 to rotate, the fan 42 draws outside air into the interior of the outer shell 1, and the inhaled air is filtered through the filter cylinder 3. The filter cylinder 3 is cylindrical and the impurities and dust that are adsorbed and filtered will remain on the outer surface of the filter cylinder 3.

[0027] Please refer again Figure 1 and Figure 3 A connecting rod 7 is rotatably connected to the fixed frame 4, one end of the connecting rod 7 extends to the outside of the outer shell 1, one end of the connecting rod 7 is installed with a tension spring, the other end of the tension spring is fixedly connected to an impact ball 71, the other end of the connecting rod 7 is fixedly connected to a driven wheel, and a driving wheel is fixedly connected to the rotating rod 41, and the driving wheel and the driven wheel are connected by a transmission belt. When the rotating rod 41 rotates, the connecting rod 7 is driven to rotate under the action of the set driving wheel, driven wheel and transmission belt, and the impact ball 71 stretches the tension spring under the action of centrifugal force, so that the impact ball 71 repeatedly knocks the filter screen cylinder 3 to shake off the dust and impurities adhered to the filter screen cylinder 3, thereby preventing the filter screen cylinder 3 from being blocked and affecting the ventilation effect.

[0028] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 A fixing plate 5 and an electric heating tube 6 are fixedly connected inside the outer shell 1. A ventilation slot 51 is opened on the fixing plate 5. A movable baffle 52 for shielding the ventilation slot 51 is hinged on the fixing plate 5 through a pin shaft. The air sucked into the outer shell 1 is heated by starting the electric heating tube 6 to prevent cold air from directly entering and affecting the crops. When ventilation is not needed, the ventilation slot 51 is shielded by the movable baffle 52 to keep the interior of the greenhouse warm.

[0029] Please refer again Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The outer shell 1 is provided with a flipping mechanism for controlling the movable baffle 52 to flip and open. The flipping mechanism includes a connecting rope 8 fixed to the movable baffle 52. The top of the connecting rope 8 is fixedly connected to the iron block 81. The inner top wall of the outer shell 1 is fixedly connected with an electromagnet 82. The electromagnet 82 is arranged just above the iron block 81. There are multiple movable baffles 52, and the multiple movable baffles 52 are connected by the connecting rope 8. The outer shell 1 is fixedly connected with a controller 9. By energizing the electromagnet 82, the electromagnet 82 generates magnetism, and the iron block 81 is adsorbed by the electromagnet 82 to pull the connecting rope 8 up. Under the connection action of the multiple connecting ropes 8, the multiple movable baffles 52 are driven to flip and open the ventilation slot 51 to allow air to circulate normally. When the greenhouse needs to be insulated, the electromagnet 82 is powered off and loses its magnetism. Under the action of gravity, the movable baffle 52 automatically flips to block the ventilation slot 51.

[0030] Working principle: the outer shell 1 is installed at a suitable position on the greenhouse, and the ventilation pipe 2 is installed inside the greenhouse. When the inside of the greenhouse needs to be ventilated, the driving motor 43 is started to drive the rotating rod 41 to rotate, and the fan 42 draws the outside air into the inside of the outer shell 1, and filters the air through the filter screen cylinder 3. The air sucked into the inside of the outer shell 1 passes through the ventilation slot 51 and then is heated by the electric heating pipe 6, and is discharged through the ventilation holes 21 on the ventilation pipe 2 so that the air is evenly filled into the interior of the greenhouse for ventilation. The connecting rotating rod 7 is driven to rotate under the action of the set active wheel, driven wheel and transmission belt, and the impact ball 71 stretches the tension spring under the action of centrifugal force, so that the impact ball 71 repeatedly knocks the filter screen cylinder 3 to shake off the dust and impurities adhered to the filter screen cylinder 3. When ventilation is not needed, the electromagnet 82 is powered off and loses its magnetism. Under the action of gravity, the movable baffle 52 automatically flips to cover the ventilation slot 51 to keep the inside of the greenhouse warm.
