[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The present invention is further described in detail below in conjunction with the embodiments.

[0022] like Figure 1-4 As shown, a specific embodiment of the granary ventilation window opening system provided by the utility model is as follows:

[0023] An out-of-warehouse opening system for a granary ventilation window comprises a window body 1, a window opening pulling mechanism and a window closing pulling mechanism;

[0024] One side of the window body 1 is mounted on the window frame 6 through a hinge 2, with the interior of the granary as the inside and the exterior of the granary as the outside. The window body 1 can be opened toward the inside of the granary through the hinge 2. A latch assembly is provided between the inner side of the window body 1 and the window frame 6, such as Figure 3 and Figure 4 As shown, the latch assembly includes a latch 3, a lock sleeve 4 and a sleeve 5, the lock sleeve 4 is fixed on the window frame 6, the sleeve 5 is fixed to the edge of the inner side of the window body 1, the latch 3 is inserted into the sleeve 5, the end of the latch 3 is a wedge-shaped structure 7, the wedge-shaped structure 7 is inserted into the lock sleeve 4, a limit ring 8 is also fixed on the latch 3, a spring 9 is sleeved on the latch 3, and the spring 9 is located between the limit ring 8 and the sleeve 5;

[0025] The window opening pulling mechanism includes a first pull rope 10, a first installation box 11 and a first driving mechanism. A first drum 12 is rotatably installed in the first installation box 11. The first driving mechanism is used to drive the first drum 12 to rotate. The first pull rope 10 is wound around the first drum 12, and the end of the first pull rope 10 is connected to the end of the latch 3.

[0026] The window closing pulling mechanism includes a second pull rope 13, a second installation box 14 and a second driving mechanism. A second drum 15 is rotatably installed in the second installation box 14. The second driving mechanism is used to drive the second drum 15 to rotate. The second pull rope 13 is wound around the second drum 15, and the end of the second pull rope 13 is connected to the outside of the window body 1; in order to facilitate the position installation of the second installation box 14 and the connection of the second pull rope 13, a door-shaped bracket 16 is fixed on the outside of the window body 1, and a guide sleeve 17 is fixed on the door-shaped bracket 16. The second pull rope 13 passes through the guide sleeve 17 and is connected to the outside of the window body 1; a plurality of guide pulleys 18 are installed on the wall of the granary, and the second pull rope 13 is wound around the guide pulley 18; the setting of the guide pulley 18 and the guide sleeve 17 is to change the direction of the second pull rope 13 and facilitate its connection.

[0027] The second driving mechanism is a main gearbox 19, which is installed outside the granary. The main gearbox 19 has a power input shaft and two power output shafts. The power input shaft is connected to a handle or a main shaft of a motor. One of the power output shafts of the main gearbox 19 is connected to the second reel 15 through a second clutch 20.

[0028] The first driving mechanism includes a first gearbox 21 and a second gearbox 22. The first gearbox 21 is installed outside the granary, and the second gearbox 22 and the first mounting box 11 are installed inside the granary. Another power output shaft of the main gearbox 19 is connected to the first gearbox 21 through a first clutch 23 and a first transmission shaft 24. The first gearbox 21 is connected to the second gearbox 22 through a second transmission shaft. The second gearbox 22 is connected to the first reel 12 through a one-way coupling 25.

[0029] It should be noted that the main gearbox 19, the first gearbox 21 and the second gearbox 22 all have a gear transmission assembly inside, and the gear transmission assembly is used for power transmission. The gear transmission assembly is not limited to a spur gear transmission pair, but can also be a bevel gear transmission pair to change the direction of power transmission according to the installation situation. The above structures are all conventional technologies in the field, so the specific structure will not be repeated here.

[0030] During operation, the main gearbox 19, the first clutch 23 and the second clutch 20 are mainly arranged outside the granary. The operator does not need to enter the granary and can operate outside the granary. When the window is in a closed state, the latch 3 locks the window through the cooperation of the wedge structure 7 and the lock sleeve 4. The main gearbox 19 can be driven manually by the handle or by a motor. When the window of the granary needs to be opened for ventilation, the first clutch 23 is in an engaged state, and the second clutch 20 is in a disengaged state. The power input shaft of the main gearbox 19 is rotated, and the two power output shafts of the main gearbox 19 output power. Since the second clutch 20 is in a disengaged state, one of the power output shafts cannot transmit power to the second reel 15, while the other power output shaft cannot transmit power to the second reel 15. The shaft transmits power to the first gear box 21 through the first clutch 23 and the first transmission shaft 24. The first gear box 21 transmits power to the second gear box 22 through the second transmission shaft. The second gear box 22 drives the first drum 12 to rotate through the one-way coupling 25. Then the first drum 12 winds the first pull rope 10. The first pull rope 10 can pull the bolt 3, so that the wedge structure 7 at the end of the bolt 3 is separated from the lock sleeve 4. The bolt 3 is continued to be pulled to open the window. During the whole process of opening the window, the window will also pull the second pull rope 13. The second pull rope 13 pulls the second drum 15 to rotate. However, since the second clutch 20 between the second drum 15 and the main gear box 19 is in a separated state, the rotation of the second drum 15 will not affect the main gear box 19.

[0031] After ventilation is completed, the first clutch 23 is disengaged and the second clutch 20 is engaged to drive the power input shaft of the main gear box 19. The power is transmitted to the second drum 15 through the second clutch 20. The second drum 15 rotates and starts to pull the second pull rope 13. The second pull rope 13 pulls the window to close. During the closing process, since the end of the latch 3 is a wedge-shaped structure 7, the wedge-shaped structure 7 can be smoothly inserted into the lock sleeve 4. As the window is closed, the first pull rope 10 is pulled, and the first pull rope 10 pulls the first drum 12 to rotate. Since a one-way coupling 25 is arranged between the first drum 12 and the second gear box 22, the rotation of the first drum 12 does not affect the second gear box 22. Finally, under the pull of the second pull rope 13, the window is closed.

[0032] In order to facilitate the understanding of ventilation time, the following components can also be set: a door and window magnetic induction switch 26 is also provided between the inner side of the window body 1 and the window frame 6, and a timer 27 is installed outside the granary. The timer 27 is connected to the door and window magnetic induction switch 26. The door and window magnetic induction switch 26 is used to monitor the window opening state, and the timer 27 is used to time the window opening time; when the window is opened, the door and window magnetic induction switch 26 transmits the monitoring information to the timer 27, and the timer 27 starts timing. The operator can know the window opening time by observing the timer 27.
